Information in this report is provided per the conditions of our approved drawings. The baseline report was submitted to you on 1/10/17. 1.0 PROJECT SUMMARY The project is a 7 -lot short plat adjacent to two wetlands; Wetland A (Category IV wetland) and Wetland B (Category IV wetland). An off-site stream within Wetland B has been classified by the City as a Type 3 (Np) watercourse. The mitigation plan included conifer supplementation within the buffers along the east side of the plat. 2.0 VEGETATION MONITORING Three photo -points were established during our 11/14/17 baseline monitoring assessment. These are used to provide a visual assessment of individual trees. Survival is determined through live plant count. Following is the performance standard for the mitigation as approved by the City. 2.1 OBJECTIVE A Increase the habitat value of the buffer over current conditions. 2.1A Performance Standard A Per the approved plan, monitoring is required for 5 years — through fall 2021. At Year 1 there will be 100% survival of all planted species Following Years 2-5, there will be 80% survival of planted species or equivalent replacement of a combination of planted and re -colonized native species. Andrea Cummins June 18, 2018 Page 2 of 3 2.1B Status of Performance Standard A at Year 1 Forty-four woody plants were installed within the buffer and restoration areas. 6 cedar, 5 Douglas fir and 24 scouler willow cuttings did not survive through the first year and were replanted in February 2018. Replanting led to meeting the performance standards. 3.0 PHOTOS FROM ESTABLISHED PHOTO -POINT LOCATIONS During the baseline monitoring event three photo -points were established that will be monitored throughout the five-year performance monitoring period. The photos, whose locations are depicted on the attached as -built plan, will be taken throughout the monitoring period to document the general appearance and progress in plant community establishment. Review of the photos over time will provide a semi -quantitative representation of success of the planting plan. Following are the photos taken during the baseline review. Photo -point 1. View looking SE to SW over the restoration area on 2/22/18. Photo -point 2. View looking north to south over the restoration area on 2/22/18. Photo -point 3. View looking north to south over the restoration area on 2/22/18. Andrea Cummins June 18, 2018 Page 3 of 3 4.0 MAINTENANCE RECOMMENDATIONS The following items need to be completed during the ongoing maintenance visits each year to ensure continued success of the mitigation areas. 1. Remove weeds within a 5' diameter of each tree within the growing season. 2. Weekly hand -watering during July, August, and September ensuring complete saturation of the root zone. 3. Plant counts will be conducted by AOA in the fall of this year to determine if replacement plants are necessary. 5.0 SUMMARY & MONITORING SCHEDULE The site is meeting the performance standards at Year 1 due to the recent replanting of the plantings that died. Recommended maintenance should be implemented to ensure survival. Monitoring is required for 5 years through Fall 2021 per the approved plan.

There are two Category P/ wetlands and associated 50 -foot buffers on the project site, and there is one Type 3 watercourse running adjacent to the east property line of the project and associated 80 -foot wide buffer. The project proposes installation of a storm drainage system connecting from lots 2 and 3 into wetland buffer and stream buffer areas at the northeastern corner of the project site. Proposed mitigation includes invasive species management and installation of native species plantings. SEPA This project is categorically exempt from a SEPA threshold determination under WAC 197-11-800 (1) Minor new construction and RCW 43.2C.0383. BACKGROUND This project involves work within sensitive area buffers for installation of a storm drainage system that will serve seven new single family homes. Sensitive areas located on the project site include two Category P/ wetlands and a Type 3 watercourse. Wetland A is located in the northeastern corner of the project site, and Wetland B is located in the southeastern corner of the project site. The watercourse runs along the east side of the project site on the east side of the wetlands. The watercourse and wetland areas are located at the bottom of a steep slope area that covers the eastern half of the site. Sensitive area buffers are located within the steep slope area, extending all the way up to the top of the slope. Work within sensitive areas includes installation of a portion of the storm drainage system in the northeastern corner of the site where the buffers of Wetland A and the watercourse are overlapping. The new homes will be located outside of sensitive buffer areas, and a wooden fence is proposed along the edge of the buffer to clearly identify the edge of the wetland buffer area. On Lot 7, the applicant is requesting to reduce the required buffer setback for structures from 10 feet to 5 feet. Lot 7 is the lot most constrained by the watercourse buffer. The applicant has submitted a site plan of the future home on Lot 7 to demonstrate how a single family home will be configured on the lot. The size of the new home on Lot 7 will be small in order to comply with required building and sensitive area buffer setback requirements. A conceptual mitigation plan that includes invasive species management and native species plantings has been prepared for the project and submitted with application materials. DECISION CRITERIA Alterations to sensitive areas are discouraged and are only allowed for specific uses. The uses permitted within sensitive areas and their buffers are listed in section 18.45.070. New surface water discharges to sensitive areas or their buffers from detention facilities is listed as number 2 under section (B) Permitted Uses Sicbject to Administrative Review. Use of sensitive areas dr their buffers for new surface water discharges is subject to a Type 2 Decision and subject to meeting the remaining criteria in TMC Chapter 18.45. This project requests administrative approval for alterations to a wetland buffer and watercourse buffer areas. Alterations to wetlands and wetland buffers are subject to the criteria in 18.45.090, including (B) Alterations, (C) Mitigation Sequencing, and (E) Mitigation Standards, and (F) Wetland and Buffer Mitigation Location. Discussion of project consistency with criteria for alterations to wetlands and wetland buffers are contained in Section I of this report. Alterations to watercourse buffer areas are subject to the criteria of TMC 18.45.110. Discussion of project! consistency with watercourse alteration criteria is in Section II of this report, followed by a discussion of the mitigation plan in Section III, and comments, conclusions and recommendations. SECTION I: WETLAND USES, ALTERATIONS AND MITIGATION (TMC 18.45.090) The mitigation plan submitted with application materials indicates all impacts to wetland buffers will be temporary and total area of temporary buffer impacts is 929 square feet. Impacts to the wetland buffer proposed with this project will mostly be temporary because the majority of the storm drainage system will be located underground. However, the storm drainage pipe will be day lighted adjacent to the dispersion pad next to the edge of Wetland A. The area where the pipe will be day lighted and the area where the rip rap/dispersion pad will be constructed are permanent impacts. Alterations (TMC 18.45.090B(1)) a. The alteration will not adversely affect water quality; A detention tank is proposed to contain water collected from the sidewalk and roadway along Macadam Rd S prior to discharging it to Wetland A. The detention tank is being added to provide water quality treatment prior to the storm water being released into Wetland A. Storm drainage on the project site shall meet the requirements of the 2009 King County Storm water Pollution Prevention Manual. b. The alteration will not adversely affect fish, wildlife, or their habitat; Existing wetland and wetland buffer areas affected by this project are currently degraded due to a combination of nearby urban land uses, low habitat diversity, and the presence of invasive species vegetation. Mitigation objectives of wetland buffer enhancement required with this project include improving the complexity of wetland wildlife habitat by increasing the structural diversity of the native wetland plant community and protecting wetlands and their buffers from erosion and sedimentation. Page 2 of 7 c. The alteration will not have an adverse effect on drainage and/or storm water detention capabilities; The project is required to meet or exceed the requirements of the 2009 King County Surface Water Design Manual. d. The alteration will not lead to unstable earth conditions or create an erosion hazard or contribute to scouring actions; A geotechnical report was submitted with application materials, which assesses site conditions and prpvides recommendations for subgrade preparation, earthwork during wet weather conditions, and ground improvement to prevent unstable earth conditions, erosion hazards or scouring from occurring. A temporary erosion and sedimentation control plan will be reviewed and implemented as part of the construction permit, and the project shall follow the recommendations of the geotechnical report. e. The alteration will not be materially detrimental to any other property; and Existing drainage from the roadway of Macadam Rd. S. flows onto the site and naturally flows to the wetland and stream areas on the site. The neighboring property owner to the north commented during the notice of application period for this project on the large amount of storm water flowing onto her property from Macadam Rd S. Installation of a catch basin at the north end of the new sidewalk proposed with this project will capture some of the storm water that is currently flowing across Macadam Rd S towards the property to the north. This storm water, along with storm water collected from the driveways of each of the new homes, will be directed to the underground storage tank where it will be held prior to discharging to the wetland in order to maintain the existing rate of flow. Storm water from the rooftops of the new homes will be captured and directed into a piped storm drain system that will ultimately be discharged into Wetland A. These improvements should have the effect of reducing the amount of storm water that flows from the project site onto adjacent properties. f. The alteration will not have adverse effects on any other sensitive areas. The proposed alteration is in an area where a wetland and watercourse buffer overlap. A discussion of project consistency with 18.45.110 Watercourse Alterations and Mitigation Standards is in Section II of this staff report. The storm system will retain storm water collected from pollution -generating paved areas. This should improve the water quality of the storm water entering the wetland and stream associated with the project site. The watercourse on the property is part of a stream system that eventually connects to the Duwamish River. Mitigation Sequencing (TMC 18.45.090 C) When an applicant proposes a use with potential wetland and/or buffer impacts, they must demonstrate that they have undergone the following mitigation sequencing. (TMC 18.45.090(C)) Applicants must demonstrate that reasonable efforts have been examined with the intent to avoid and minimize impacts to wetland and buffers. If a wetland/buffer alteration cannot be avoided, then an alteration to a wetland or its required buffer shall be minimized or compensated for and must satisfy the Alteration Criteria. (TMC 18.45.090(B) All of these steps must occur in the following sequence. Page 3 of 7 1. Avoiding the impact altogether by not taking a certain action or parts of an action. 2. Minimizing wetland and buffer impacts by limiting the degree or magnitude of the action. 3. Rectifying the impact by repairing, rehabilitating or restoring the affected environment. 4. Reducing or eliminating the impact over time by preservation and maintenance operations during life of the action. 5. Compentating for the impact by replacing, enhancing or providing substitute resources or environments. 6. Monitoring the impact and taking appropriate corrective measures. All of the new homes in the project are proposed to be constructed at the front of the lots, outside 'of sensitive area buffers. All work for installation of the utilities and construction of the homes will also be located outside of the sensitive areas and sensitive area buffers, with the exception of installation of the storm drainage pipe and riprap dispersion pad. Page 2 of the mitigation plan prepared by Altmann Oliver Associates includes the following description of avoidance and minimization for this project: ' "The proposed Macadam Short Plat has been designed to avoid all permanent impacts to the sensitive areas and their buffers. The only work that must occur within the buffer is the installation of an above -ground storm water conveyance pipe and associated dispersion pad along the islope in the northeastern portion of the site. This pipe would be installed within a heavily disturbed portion of the buffer and would be designed to avoid any significant native vegetation. It is my understanding that a storm water filtration system has been designed by Azure/Green Consultants LLC that would also treat all collected storm water runoff prior to release into the wetland." This project avoids construction of the new homes within buffer areas. Construction within buffer areas is limited to storm drainage improvements designed to improve storm drainage conditions on site and on surrounding properties. Disturbed buffer areas will be restored and enhanced with native plantings, and native species conifer trees will be planted throughout the entire buffer area. Monitoring and maintenance of the mitigation will occur for five years following final installation of the plantings. Mitigation Standards (TMC 18.45.090 E) There are a variety of types of mitigation that may be provided for wetland alterations, following mitigation sequencing steps. The different types of wetland mitigation are listed in TMC 18.45.090 (E) (1), and include Restoration (re-establishment and/or rehabilitation), Creation, and Enhancement. A combination of these mitigation types may be used to achieve mitigation requirements. The amount of mitigation required is dependent on the wetland Category proposed for alteration and the type of mitigation proposed. Permanent wetland buffer impacts shall be mitigated at a ratio of 1:1 for all wetland Categories when feasible. Buffers temporarily disturbed shall be restored to better than pre -project conditions. Restoration and enhancement are the types of mitigation proposed for impacts to wetland buffers proposed with this project. The existing wetland buffers are degraded, and the proposed mitigation to the buffers of wetlands A and B will improve buffer conditions and functions over the original state. Per page 3 of the mitigation plan, the disturbed area will be restored with Red Fescue seed after installation of the storm drainage system. Black Twinberry (Lonicera involucrate) cuttings will be installed along the outfall pad. Within the entire buffer area, invasive species (monotypic blackberry Page 4 of 7 patches) are proposed to be mowed, and 20 conifer trees will be planted. In order that the new trees and cuttings are able to thrive within the restored buffer area, a condition of approval of this permit is that the specifications on Sheet 3 of 3 of the mitigation plan be modified according to redlined mark-ups in the attached sheets of the mitigation plan to (1) include removal of roots of invasive plants in the immediate tree planting areas prior to planting; and (2) to change the language of the Container Tree Planting Detail from "do not disturb Irootball" to "loosen root ball and prune any circling roofs prior to planting". Additionally, one sign per lot that complies with TMC 18.45.060 shall be placed on the fence to ensure future homeowners are aware of the presence of sensitive areas located on their properties, and to promote stewardship of these areas. 1 Maintenance and monitoring of the mitigation area is required for a minimum of five years. Mitigation plan sheets 3-4 include information on the proposed monitoring methodology and maintenance plan. A five-year maintenance and monitoring period is proposed, with maintenance to be conducted on a routine, year-round basis, and a contingency plan is specified in case plantings within the area do not survive. A monitoring report will be submitted every year for the duration of the five-year period. SECTION II: WATERCOURSE DESIGNATIONS, RATINGS AND BUFFERS (TMC 18.45.I00) This project does not propose a variation of the watercourse buffer width, but instead proposes use of the watercourse buffer area for storm drainage purposes. Use of the buffer area for storm drainage is considered an alteration. Below are the criteria applicable to alterations proposed within watercourse buffer areas, followed by a review of project compliance with each of the criteria. Alterations (TMC 18.45.110 B) 1. Diverting or rerouting may only occur with the permission of the Director and an approved mitigation plan. There is no diverting or rerouting of the watercourse proposed as part of this project. 2. Any watercourse that has critical wildlife habitat, or is necessary for the life cycle or spawning of salmonids, shall not be rerouted unless it can be shown that the habitat will be improved for the benefit of the species. The watercourse will not be rerouted as part of this project. 3. A watercourse may be rerouted or day lighted as a mitigation measure to improve watercourse function. The watercourse is currently day lighted and will not be rerouted as part of this project. 4. As a condition of approval, the Director may require water quality monitoring for storm water discharges to streams, and additional treatment of storm water if water quality standards are not being met. Storm drainage design for this project is required to meet the 2009 King County Surface Design Manual. Driveways and a portion Macadam Road will collect in a water detention system and be retained prior to discharging to a dispersion pad connected to Wetland A. House roof drains will be connected to a private storm system which ultimately connects to the same pipe that discharges storm water from the detention system to Wetland A. Page 5 of 7 5. Piping of any watercourse shall be avoided. Relocation of a watercourse or installation of a bridge is preferred to piping. If piping occurs in a watercourse sensitive area, it shall be limited to requirements for stream crossings for access and shall require approval of the Director. Piping is not proposed for watercourses within the project area. Mitigation Standards (TMC 18.45.110 D 2) The following shall be considered the minimum standards for approved stream alterations: a. Maintenance or improvement of stream channel habitat and dimensions such that the fisheries habitat functions of the compensatory stream reach or exceed that of the original stream; Impacts and mitigation associated with this project are proposed within the stream buffer. There is no work proposed within the stream channel. b. Bank and buffer configuration restored to an enhanced state; The west side of the watercourse is the portion located on the project site, and is in a degraded state. The east side of the watercourse was enhanced by Sound Transit as part of Link Light Rail construction. Proposed installation of native species cuttings and hydro seed within the areas to be directly disturbed, along with removal of invasive species plants, and the addition of 20 conifer trees to the buffer area will restore the watercourse buffer to an enhanced state. c. Channel, bank and buffer areas replanted with native vegetation that improves the original in species diversity and density; The existing stream buffer condition is degraded due to the presence of invasive species within the project area. Buffer area enhancement, including invasive species management and native plantings to enhance the area around the watercourse will provide an improvement over original species diversity and density. d. Stream channel bed and biofiltration systems equivalent to (in the case of public drainage maintenance projects) and better than in the original stream (in the case of other kinds of projects); There are not proposed alterations to the stream channel bed as part of this project. All impacts and mitigation will occur within the stream buffer. e. Original fish and wildlife habitat enhanced unless technically not feasible. The watercourse buffer will be enhanced with native species plantings. This will improve wildlife habitat over existing conditions. COMMENTS A Notice of Application was mailed on June 9, 2014 to the applicant and to departments and agencies with jurisdiction pursuant to TMC 18.104.090, and to property owners and tenants within 500 feet of the project site pursuant to 18.104.120. The site was posted on June 9, 2014 pursuant to TMC 18.104.110. One comment letter on the project, from Mrs. Thelma Davis, was submitted to the City of Tukwila during the Notice of Application period. A copy of Mrs. Davis' letter is attached, along with responses to comments from both the applicant and the City. Page 6 of 7 CONCLUSIONS 1. New surface water discharges to sensitive areas or their buffers from detention facilities or other surface water management structures is permitted subject to the clean water standards of RCW 90.48 and WAC 173.200 and 173.201, and provided the discharge does not adversely affect water level fluctuations in the wetland or adversely affect watercourse habitat and watercourse flow conditions relative to the existing rate. 2. The applicant has demonstrated compliance with mitigation sequencing. 3. The area of permanent buffer impacts is being mitigated at a ratio that is greater than 1:1 and the entire buffer area restored and enhanced to better than pre -project conditions through the addition of 20 conifer 'trees. 4. The applicant has submitted a site plan showing how the new home on Lot 7 will be configured on the lot so as not to encroach within the wetland and stream buffer areas. Per TMC18.45.080 E, the Director may waive buffer setback requirements when a site plan demonstrates there will be no impacts to the buffer from construction or occasional maintenance activities. 5. In order that the new trees and cuttings are able to thrive within the restored buffer areas, a condition of approval of this permit is that the specifications on Sheet 3 of 3 of the mitigation plan be modified according to redlined mark-ups in the attached sheets of the mitigation plan to (1) include removal of roots of invasive plants in the immediate tree planting areas prior to planting; and (2) to change the language of the Container Tree Planting Detail from "do not disturb root ball" to "loosen root ball and prune any circling roots prior to planting". 6. Additionally, one sign per lot that complies with TMC 18.45.060 shall be placed on the fence to ensure future homeowners are aware of the presence of sensitive areas located on their properties, and to promote stewardship of these areas. RECOMMENDATIONS Staff recommends approval of the Special Permission permit for work within wetland and stream buffers, and for a reduction in the buffer setback width, with the following conditions: 1. Sheet 3 of 3, Specification 2. Add: "Roots of invasive plants in the immediate tree planting areas shall be removed prior to planting." 2. Sheet 3 of 3, Container Tree Planting Detail. Change language that states "do not disturb rootball" to "loosen root ball and prune any circling roots prior to planting". 3. One sign per lot that complies with TMC 18.45.060.6 shall be placed on the fence separating the homes from buffer areas. ATTACHMENTS: a.

Davis 13806 Macadam Rd.3 Tukwila, WA June 20, 2014 City of Tukwila Department of Community Development ATTN: Jaimie Reavis 6300 Southcenter Blvd, #100 Tukwila, WA Re: File #5 L13-029 (Short Plat) L14-0001 (Special Permission) Project #13-0028 Dear Jaimie: Thank you for meeting with me and my sister, Donna Morris, on June 12th regarding the project site. The major issue I have with the proposed project is regarding the "project site" is water drainage. A. Background My property is located at 13806 Macadam Rd and adjacent to the project site. It is North of project site and is currently at a lower elevation than the project site. Since the project site was filled in and the construction of the 3 houses on the opposite side of Macadam Rd, I have had to deal with a lot of surface water running down across the road and onto my property causing me to have a wet basement. I have had a lot of expense from water draining onto my property. When the land above the road is saturated with water and it rains, water has no place to go except on my property since the City has not put in any storm drains nor changed the road to have it drain into a ditch on the opposite side of Macadam Road. In the 1980's an old barn (See attachment, Photo copy #1) and a small pond were on the project site. The area was at a lower elevation than my property. I never had any problems with water draining from the project site nor the road. The prior landowner of the project site in his anticipation of a subdivision into 7 lots and constructing seven houses, had material dumped to raise the level. My husband (deceased) and I watched many of the loads of material being dumped. There was concrete, roofing material, dirt, rocks, etc. On the south end of the "site" the fire department caught barrels being dumped which required "hazmat" removal. That only 1 of 5 raises a question as to whether other barrels had been dumped at the "site" and were not previously discovered. Additionally, we never saw the barn removed, so it is unknown if it contained anything inside of it as it was presumably crushed from the weight of the material dumped on top of it. Although, there has been some environmental testing of soil samples, it might behoove the city to require additional testing of soil at deeper levels at random locations. Not long after the project site was mounded up, we had a mud slide from that "mountain of dirt" made by prior landowner. The mud damaged our fence and came halfway to the house (See attachment, photo copies # 2&3). In the past few years, since the construction of the 3 houses across Macadam Rd, I have had to contact the fire department regarding the water running down from Macadam Rd. The firemen looked to see where the water was coming from and they found that a storm drain had been constructed higher than Macadam Rd further south and that a steady stream flowing from the hillside and across Macadam causing the water to flow over into the corner of my property which ran down like a waterfall. As the city is aware, the hillside across Macadam Rd contains a lot of water from the springs in the hillside. The ground becomes saturated from the springs and when it rains, the problem is compounded and surface water drains across Macadam Rd and onto my property. Storm drains are badly needed. B. Drainage of surface water from Macadam Road and Project Site Reading plat maps is not an easy task for a layman and therefore not absolutely sure about our interpretations. In review of the plans for the project site, it appears they have drains planned In another drawing, it shows drains but appears to just end with water draining down the hillside and that is not acceptable. In further review of the plat maps/drawings, in particular Lot #1 - Macadam Short Plat #S3, it appears that there is to be a leader to connect roof and driveway drainage to a pipe that is to run to a storm drain that will ultimately drain the water to the proposed wetland area. However, Lots 1 &2, especially Lot #1 would need to be filled to raise the level of the drain line to ensure water will be flowing down to the storm drain that is currently at the top, water does not flow uphill. The plat maps are not clear as to what is going to happen on proposed Lots #1 & 2. It appears that Lot #1 will be entirely on the slope next to my property. Will the trees and other foliage be removed, more fill be added to raise the level of that lot to that of the other lots? If so, will a retaining wall must be built to hold the dirt back from my property. If not, what will be done to ensure that water drainage during rain and lawn watering will not run down on my property? How will the dirt, etc be held back during the excavation and construction phases? Water running off the lots above will most likely contain contaminates from engine oil and coolants from vehicles which will contaminate all soil below it along with the proposed wetland area. 2 of 5 We were told the project site will have curbing, this will only mean that water from the street will run around the corner and down on my property. As shown in S3 Short Plat, it appears that the pavement and sidewalk would end at the end or at the edge of the project site. This will cause water to become a waterfall on my property during prolonged and/or heavy rain. Water flowing along the curb on the project site would need to be diverted through a pipe to the wetland area or sewer since there are no storm drains along Macadam Road to handle the surface water. C. Trees and foliage on Project Site: The trees that are currently growing on the hillside area designated as Lot #1 are "volunteer" trees. No trees were growing prior to the mudslide as can be seen in attached photo copies #1-3. The trees drop leaves and limbs and blackberry vines also grow in the ditch that was made along the outside of my fence to carry surface water from the road away from my property. The ditch was done by the city or prior landowner of the project site quite some time ago and needs to be cleaned out. - Some trees are quite large and tall enough that if they were blown down during heavy windstorm, the could fall into my house. Also would construction cause some of the Targe trees to fall towards my house? - Removal of small trees and other vegetation could cause the soil to become loose and therefore a mud/dirt slide. I do not want another mud slide like occurred in 1985. - Blackberry vines are very invasive and I do not want them on my property. Who will maintain the area to prevent the vines from growing and spreading to my property? - Who will ensure the trees do not become so tall that they will fall over damaging my property? My house is on the Tukwila Historical Society listing of historical homes and therefore, should be protected and not be damaged by falling trees and mudslides. The landowner and City must address my concerns regarding surface water and drainage along with the Targe trees to prevent further damage to my property. It would be negligent to not address the concerns about the debris that was dumped at the project site and to allow water containing contaminates to be dumped onto adjacent landowners causing damage to their homes. 3 of 5 D. Parking Parking will need to be addressed. Will there be sufficient parking for at least 2 vehicles without anyone having to park on the road? If a family has one or two teenagers who drive, that will increase the number of vehicles in their driveway. I would like to be able to get to the mailbox without having to work my way around parked vehicles blocking the gate and path to the mailbox. I have problems with walking on uneven surfaces and do not wish to fall because someone parked a car in a manner that causes me to step into a hole. Also, parking in front of my house would hamper mail delivery and emergency vehicles since there are no curbs to paint to tell people not to park there. I am assuming that the houses are to be "single family homes" and not ones that will contain multiple family members, parents, kids, grand parents, aunts, uncles and cousins, etc. Multiple family members will impact the number of vehicles. I already have neighbors with multiple family members and about 12 vehicles parked all over and some those vehicles seem to never be moved. I realize the current landowner is wanting to make a quick turnaround and gain the most profit. I realize that they are in it to make money from their investment. However, their profit should not cause harm to the neighboring properties since it will only devalue his properties in the end. It is my opinion that seven homes on the project site is too many. - Proposed Lot #1 is not a good building site as it stands. It is a hillside full of trees and other foliage that would need removal. Any drain lines connecting to a storm drain at the top of the hill will fail since water does not flow up hill. The only way it could be made into a proper building site is to build a retaining wall and fill the area to raise it to the same level as the other proposed lots. You should take a good look at this area before a decision is made about the subdivision and approval of any building permits. - Houses within 10-20 feet of each other is a fire hazard. If one catches fire, it will quickly spread to the others. - Houses placed so close only make unhappy homeowners since they will hear noises from the next house. 4 of 5 E. Requests I do want to receive a copy of the City's decision on the project. If the project is approved, I ask that the landowner or person in charge of construction to give me a 2 week notice of the beginning of the construction and an estimate of the length of the construction. Since construction is quite noisy and my health requires me to have adequate rest, I also request that: - I know my mimmosa tree is quite large and a limb may be over the fence and may need to be trimmed back. I ask that the tree not be damaged during construction. The tree is quite old and the tree means a lot to me as my father gave me the tree. When the tree blooms, it is a huge pink umbrella. - construction be done Monday through Friday, between the hours of 8:00 am and 5:00 pm. - the construction begin on the site designated as Lot #1 on the plans, closest to my property so that the house can help buffer some of the noise from the construction of the other houses and that Lot 7 be the last to be constructed. - Additionally, I ask that the construction crew not block the area in front of my gate to allow for emergency vehicles should I need one. I pray there will not be such a need. Thank you for your consideration of my concerns about the proposed project. am not opposed to having ood neighbors.

Davis I I 13806 Macadam Rd. S. Tukwila, WA 98168 Re: Comments submitted during the Notice of Application period for the Macadam Short Plat (Short Plat L13-029, Special Permission L14-0001, and Project File PL13-0028) Dear Mrs. Davis, Thank you for submitting your comment letter, dated June 20, 2014 on the Macadam Short Plat project. Multiple departments within the City, including Public Works, Fire, Building, and Planning, are reviewing the permits above. The City has code requirements to address many of the issues raised in your letter. I've coordinated with the Public Works Department to include the information below related to your concerns. The City's responses are grouped into different categories based on the comments you submitted. Storm Drainage and Slope Stability The applicant has submitted a storm drainage analysis and plan for the project, as well as a geotechnical report to assess slope stability. Along the portion of project site adjacent to Macadam Road, "The runoff from the west will be collected by the new curb and gutter that is proposed for Macadam Road and will be piped directly into the wetland/stream along the eastern property line" (p. 15, Macadam Short Plat Technical Information Report). There is a large detention system designed as part of the project which will collect the storm water from the new sidewalk and adjacent roadway area. The storm water from the road and the sidewalk will be released from the detention system into the wetland at a rate that maintains the site's pre -development rate of flow. This drainage system should have the effect of reducing the amount of storm water that flows onto your property. The location of the catch basin at the north side of the sidewalk shown on Sheet 3 of 7, and the location of the pipes connecting from the new lots to the drainage system is conceptual at this time. These will be reviewed in more detail as part of the Public Works construction permit to determine the location that will best capture the runoff from the new sidewalk and the adjacent area of Macadam Rd S and for gravity flow from individual lots to the private drainage system. Street and onsite infrastructure will be constructed per City standards, 2009 King County Surface Design Manual, and Geotechnical Reports and recommendations. Driveways and a portion of Macadam Road will collect in a storm drainage system and be retained prior to discharging to an outlet at the northeastern corner of the project site. Curb, gutter, and sidewalk will be constructed along Macadam Road. New catch basins within the street will collect the surface water and flow into the new Public storm drainage system. Future houses will be built close to Macadam Road per Geotechnical Reports and recommendations House roof drains will be connected to a Private storm drainage system and meet the 2009 King County Surface Design Manual requirements. Water quality will be provided as applicable under the 2009 King County Surface pesign Manual. Civil plan sheet 3 by Azure Green Consultants is a preliminary Road and Storm Improvements design as part of Preliminary Short Plat number L13-029. The final storm drainage design and construction will be part of alfuture Public Works permit. The houses will be constructed as part of future Building permits. Please contact David McPherson at (206) 431-2448 if you have any questions regarding storm drainage and slope stability. Trees and foliage on the project site Trees located along the north side of the project site adjacent to your property line are located within areas mapped as steep slope sensitive areas. Trees located further to the east are located within steep slope and stream buffer areas. Proposed tree removals within sensitive areas require a tree removal permit and planting of replacement trees. Trees that are not located within sensitive areas are those along the street frontage of Macadam Rd. S. Up to four significant trees may be removed for construction of the project, and removal of additional trees not located in sensitive areas may be approved if necessary for construction of the sidewalk and/or utilities. We will work with the applicant as part of review of the short plat to determine whether any trees on the project site will need to be removed. We will also work with the applicant as part of short plat review to determine whether trimming portions of the tree on your property that hang over the property line will be necessary. Parking Part of the City's review of the short plat includes making sure the project meets the parking requirements of the Tukwila Municipal Code (TMC). At least two parking spaces will be required for each new home. New homes often have two -car garages with additional paved area outside the garage for extra parking. Parking is not allowed in the right-of-way of Macadam Rd. S. In the event that any vehicles are parked in the right-of-way or on your property, they would be subject to enforcement. Additionally, one of the erosion control measures identified in the applicant's Erosion and Sediment Control Analysis is construction of an on-site temporary construction entrance and construction parking area (Macadam Short Plat Technical Information Report, page 22). Fire and Home Spacing Concerns On page 4 of your letter, you write that you're concerned about the potential for the houses to be within 10-20 feet of each other for two reasons (1) fire hazards, and (2) potential for noise. The side yard setback requirement on each lot is 5 feet, so the minimum amount of space between the homes will be 10 feet. This requirement applies to all development within the LDR zoning district, and this setback standard has been in place for some time. Since 2011, all new single-family homes are required to have an automatic sprinkler system. Project plans and building permits will be reviewed by the Fire Department for compliance with fire code requirements. The minimum lot size in the LDR zone is 6,500 square feet. The lots proposed with this short plat meet the minimum lot size requirement; lot sizes shown on plan sheets range from 7,070 to 15,205 square feet. The minimum loft width in the LDR zone is 50 feet, and the proposed loth also meet this requirement. The developable area of some of the lots are impacted due to the location of sensitive areas; however, the project is being reviewed for potential impacts to sensitive areas and proposed mitigation measures as part of the Special Permission Permit. The geotechnical report contains information on soil and slope stability, and is used to determine the areas on each lot that are best suited to the development proposed, or measures that must be taken in order for a lot to be buildable. Requests Your requests to receive a two-week notification prior to the start of construction, to have construction of the project start with Lot 1, and to limit the hours of construction to Monday through Friday between the hours of 8:00 a.m. and 5:00 p.m. are outside of what the City can require of the developer. The City limits construction noise to the hours of 7:00 a.m. to 10:00 p.m. Monday through Friday and 8:00 a.m. to 10:00 p.m. on Saturday, Sunday, and State -recognized holidays. Attached is the developer's letter in response to your comments and requests. You will receive a copy of the City's decisions on the Special Permission and Short Plat permits.

Davis File #5 L13-029 (Short Plat) 114-0001 (Special Permission) Project #13-0028 Dear Jaimie: We are writing letter in response to the one you received from Thelma F. Davis, the neighbor to the north of our project. Mrs. Davis said her primary concern was storm drainage. Our project should actually improve her situation some. We are proposing curb and gutter along our frontage which will collect any drainage on Macadam Road along our frontage and convey it to our proposed detention pipe. The proposed outfall from our detention system is below her house near a wetland located in the NE corner of our project site. The drainage from the roofs and driveways on our project site will also be conveyed to the proposed detention pipe and will also bypass her property. The net result should be Tess drainage from our site impacting her property. It appears the majority of her storm drainage concerns are problems that our site does not contribute to. Her concerns about seepage/drainage from the hillside west of her house and the lack of an adequate storm system in Macadam Road are not problems to which we contribute and will not be addressed by our project. She also mentioned slope stability and a concern about unsuitable fill material being placed on the project site. There are several geotechnical reports addressing these two items that are public records. We will adhere to the recommendations in the reports for our project. There are numerous other concerns about parking, single family residences, working hours, etc. that are all covered by the Zoning Code and existing regulations which we feel it is not necessary to respond to. We will try to construct the house on proposed lot 1 first to the best of our ability. We cannot guarantee that will be the case but we will certainly take her comment into account in our planning for the home construction phase. a z u r e g r e e n c o n s u l t a n t s c o m Please contact our office if you need any additional information.

There are two Category IV wetlands and associated 50 -foot buffers on the project site, and there is one Type 3 watercourse running adjacent to the east property line of the project and associated 80 -foot wide buffer. The project proposes installation of a storm drainage system connecting from lots 2 and 3 into wetland buffer and stream buffer areas at the northeastern corner of the project site. Proposed mitigation includes invasive species management and installation of native species plantings. SEPA This project is categorically exempt from a SEPA threshold determination under WAC 197-11-800 (1) Minor new construction and RCW 43.2C.0383. BACKGROUND This project involves work within sensitive area buffers for installation of a storm drainage system that will serve seven new single family homes. Sensitive areas located on the project site include two Category IV wetlands and a Type 3 watercourse. Wetland A is located in the northeastern corner of the project site, and Wetland B is located in the southeastern corner of the project site. The watercourse runs along the east side of the project site on the east side of the wetlands. The watercourse and wetland areas are located at the bottom of a steep slope area that covers the eastern half of the site. Sensitive area buffers are located within the steep slope area, extending all the way up to the top of the slope. Work within sensitive areas includes installation of a portion of the storm drainage system in the northeastern corner of the site where the buffers of Wetland A and the watercourse are overlapping. The new homes will be located outside of sensitive buffer areas, and a wooden fence is proposed along the edge of the buffer to clearly identify the edge of the wetland buffer area. On Lot 7, the applicant is requesting to reduce the required buffer setback for structures from 10 feet to 5 feet. Lot 7 is the lot most constrained by the watercourse buffer. The applicant has submitted a site plan of the future home on Lot 7 to demonstrate how a single family home will be configured on the lot. The size of the new home on Lot 7 will be small in order to comply with required building and sensitive area buffer setback requirements. A conceptual mitigation plan that includes invasive species management and native species plantings has been prepared for the project and submitted with application materials. DECISION CRITERIA Alterations to sensitive areas are discouraged and are only allowed for specific uses. The uses permitted within sensitive areas and their buffers are listed in section 18.45.070. New surface water discharges to sensitive areas or their buffers from detention facilities is listed as number 2 under section (B) Permitted Uses Subject to Administrative Review. Use of sensitive areas Or their buffers for new surface water discharges is subject to a Type 2 Decision and subject to meeting the remaining criteria in TMC Chapter 18.45. This project requests administrative approval for alterations to a wetland buffer and watercourse buffer areas. Alterations to wetlands and wetland buffers are subject to the criteria in 18.45.090, including (B) Alterations, (C) Mitigation Sequencing, and (E) Mitigation Standards, and (F) Wetland and Buffer Mitigation Location. Discussion of project consistency with criteria for alterations to wetlands and wetland buffers are contained in Section I of this report. Alterations to watercourse buffer areas are subject to the criteria of TMC 18.45.110. Discussion of project' consistency with watercourse alteration criteria is in Section II of this report, followed by a discussion of the mitigation plan in Section III, and comments, conclusions and recommendations. SECTION I: WETLAND USES, ALTERATIONS AND MITIGATION (TMC 18.45.090) The mitigation plan submitted with application materials indicates all impacts to wetland buffers will be temporary and total area of temporary buffer impacts is 929 square feet. Impacts to the wetland buffer proposed with this project will mostly be temporary because the majority of the storm drainage system will be located underground. However, the storm drainage pipe will be day lighted adjacent to the dispersion pad next to the edge of Wetland A. The area where the pipe will be day lighted and the area where the rip rap/dispersion pad will be constructed are permanent impacts. Alterations (TMC 18.45.090B(1)) a. The alteration will not adversely affect water quality; A detention tank is proposed to contain water collected from the sidewalk and roadway along Macadam Rd S prior to discharging it to Wetland A. The detention tank is being added to provide water quality treatment prior to the storm water being released into Wetland A. Storm drainage on the project site shall meet the requirements of the 2009 King County Storm water Pollution Prevention Manual. b. The alteration will not adversely affect fish, wildlife, or their habitat; Existing wetland and wetland buffer areas affected by this project are currently degraded due to a combination of nearby urban land uses, low habitat diversity, and the presence of invasive species vegetation. Mitigation objectives of wetland buffer enhancement required with this project include improving the complexity of wetland wildlife habitat by increasing the structural diversity of the native wetland plant community and protecting wetlands and their buffers from erosion and sedimentation. Page 2of7 c. The alteration will not have an adverse effect on drainage and/or storm water detention capabilities; The project is required to meet or exceed the requirements of the 2009 King County Surface Water Design Manual. d. The alteration will not lead to unstable earth conditions or create an erosion hazard or contribute to scouring actions; A geotechnical report was submitted with application materials, which assesses site conditions and provides recommendations for subgrade preparation, earthwork during wet weather conditions, and ground improvement to prevent unstable earth conditions, erosion hazards or scouring from occurring. A temporary erosion and sedimentation control plan will be reviewed and implemented as part of the construction permit, and the project shall follow the recommendations of the geotechnical report. e. The alteration will not be materially detrimental to any other property; and Existing drainage from the roadway of Macadam Rd. S. flows onto the site and naturally flows to the wetland and stream areas on the site. The neighboring property owner to the north commented during the notice of application period for this project on the large amount of storm water flowing onto her property from Macadam Rd S. Installation of a catch basin at the north end of the new sidewalk proposed with this project will capture some of the storm water that is currently flowing across Macadam Rd S towards the property to the north. This storm water, along with storm water collected from the driveways of each of the new homes, will be directed to the underground storage tank where it will be held prior to discharging to the wetland in order to maintain the existing rate of flow. Storm water from the rooftops of the new homes will be captured and directed into a piped storm drain system that will ultimately be discharged into Wetland A. These improvements should have the effect of reducing the amount of storm water that flows from the project site onto adjacent properties. f. The alteration will not have adverse effects on any other sensitive areas. The proposed alteration is in an area where a wetland and watercourse buffer overlap. A discussion of project consistency with 18.45.110 Watercourse Alterations and Mitigation Standards is in Section II of this staff report. The storm system will retain storm water collected from pollution -generating paved areas. This should improve the water quality of the storm water entering the wetland and stream associated with the project site. The watercourse on the property is part of a stream system that eventually connects to the Duwamish River. Mitigation Sequencing (TMC 18.45.090 C) When an applicant proposes a use with potential wetland and/or buffer impacts, they must demonstrate that they have undergone the following mitigation sequencing. (TMC 18.45.090(C)) Applicants must demonstrate that reasonable efforts have been examined with the intent to avoid and minimize impacts to wetland and buffers. If a wetland/buffer alteration cannot be avoided, then an alteration to a wetland or its required buffer shall be minimized or compensated for and must satisfy the Alteration Criteria. (TMC 18.45.090(B) All of these steps must occur in the following sequence. Page 3 of 7 1. Avoiding the impact altogether by not taking a certain action or parts of an action. 2. Minimizing wetland and buffer impacts by limiting the degree or magnitude of the action. 3. Rectifying the impact by repairing, rehabilitating or restoring the affected environment. 4. Reducing or eliminating the impact over time by preservation and maintenance operations during life of the action. 5. Compensating for the impact by replacing, enhancing or providing substitute resources or environments. 6. Monitoring the impact and taking appropriate corrective measures. All of the new homes in the project are proposed to be constructed at the front of the lots, outside of sensitive area buffers. All work for installation of the utilities and construction of the homes will also be located outside of the sensitive areas and sensitive area buffers, with the exception of installation of the storm drainage pipe and riprap dispersion pad. Page 2 of the mitigation plan prepared by Altmann Oliver Associates includes the following description of avoidance and minimization for this project: ' "The proposed Macadam Short Plat has been designed to avoid all permanent impacts to the sensitive areas and their buffers. The only work that must occur within the buffer is the installation of an above -ground storm water conveyance pipe and associated dispersion pad along the ,slope in the northeastern portion of the site. This pipe would be installed within a heavily disturbed portion of the buffer and would be designed to avoid any significant native vegetation. It is my understanding that a storm water filtration system has been designed by Azure/Green Consultants LLC that would also treat all collected storm water runoff prior to release into the wetland." This project avoids construction of the new homes within buffer areas. Construction within buffer areas is limited to storm drainage improvements designed to improve storm drainage conditions on site and on surrounding properties. Disturbed buffer areas will be restored and enhanced with native plantings, and native species conifer trees will be planted throughout the entire buffer area. Monitoring and maintenance of the mitigation will occur for five years following final installation of the plantings. Mitigation Standards (TMC 18.45.090 E) There are a variety of types of mitigation that may be provided for wetland alterations, following mitigation sequencing steps. The different types of wetland mitigation are listed in TMC 18.45.090 (E) (1), and include Restoration (re-establishment and/or rehabilitation), Creation, and Enhancement. A combination of these mitigation types may be used to achieve mitigation requirements. The amount of mitigation required is dependent on the wetland Category proposed for alteration and the type of mitigation proposed. Permanent wetland buffer impacts shall be mitigated at a ratio of 1:1 for all wetland Categories when feasible. Buffers temporarily disturbed shall be restored to better than pre -project conditions. Restoration and enhancement are the types of mitigation proposed for impacts to wetland buffers proposed with this project. The existing wetland buffers are degraded, and the proposed mitigation to the buffers of wetlands A and B will improve buffer conditions and functions over the original state. Per page 3 of the mitigation plan, the disturbed area will be restored with Red Fescue seed after installation of the storm drainage system. Black Twinberry (Lonicera involucrate) cuttings will be installed along the outfall pad. Within the entire buffer area, invasive species (monotypic blackberry Page 4 of 7 patches) are proposed to be mowed, and 20 conifer trees will be planted. In order that the new trees and cuttings are able to thrive within the restored buffer area, a condition of approval of this permit is that the specifications on Sheet 3 of 3 of the mitigation plan be modified according to redlined mark-ups in the attached sheets of the mitigation plan to (1) include removal of roots of invasive plants in the immediate tree planting areas prior to planting; and (2) to change the language of the Container Tree Planting Detail from "do not disturb Irootball" to "loosen root ball and prune any circling roots prior to planting". Additionally, one sign per lot that complies with TMC 18.45.060 shall be placed on the fence to ensure future homeowners are aware of the presence of sensitive areas located on their properties, and to promote stewardship of these areas. Maintenance and monitoring of the mitigation area is required for a minimum of five years. Mitigation plan sheets 3-4 include information on the proposed monitoring methodology and maintenance plan. A five-year maintenance and monitoring period is proposed, with maintenance to be conducted on a routine, year-round basis, and a contingency plan is 'specified in case plantings within the area do not survive. A monitoring report will be submitted every year for the duration of the five-year period. SECTION II: WATERCOURSE DESIGNATIONS, RATINGS AND BUFFERS (TMC 18.45.I00) This project does not propose a variation of the watercourse buffer width, but instead proposes use of the watercourse buffer area for storm drainage purposes. Use of the buffer area for storm drainage is considered an alteration. Below are the criteria applicable to alterations proposed within watercourse buffer areas, followed by a review of project compliance with each of the criteria. Alterations (TMC 18.45.110 B) 1. Diverting or rerouting may only occur with the permission of the Director and an approved mitigation plan. There is no diverting or rerouting of the watercourse proposed as part of this project. 2. Any watercourse that has critical wildlife habitat, or is necessary for the life cycle or spawning of salmonids, shall not be rerouted unless it can be shown that the habitat will be improved for the benefit of the species. The watercourse will not be rerouted as part of this project. 3. A watercourse may be rerouted or day lighted as a mitigation measure to improve watercourse function. The watercourse is currently day lighted and will not be rerouted as part of this project. 4. As a condition of approval, the Director may require water quality monitoring for storm water discharges to streams, and additional treatment of storm water if water quality standards are not being met. Storm drainage design for this project is required to meet the 2009 King County Surface Design Manual. Driveways and a portion Macadam Road will collect in a water detention system and be retained prior to discharging to a dispersion pad connected to Wetland A. House roof drains will be connected to a private storm system which ultimately connects to the same pipe that discharges storm water from the detention system to Wetland A. Page 5 of 7 5. Piping of any watercourse shall be avoided. Relocation of a watercourse or installation of a bridge is preferred to piping. If piping occurs in a watercourse sensitive area, it shall be limited to requirements for stream crossings for access and shall require approval of the Director. Piping is not proposed for watercourses within the project area. Mitigation Standards (TMC 18.45.110 D 2) The following shall be considered the minimum standards for appro fed stream alterations: a. Maintenance or improvement of stream channel habitat and dimensions such that the fisheries habitat functions of the compensatory stream reach or exceed that of the original stream; Impacts and mitigation associated with this project are proposed within the stream buffer. There is no work proposed within the stream channel. b. Bank and buffer configuration restored to an enhanced state; The west side of the watercourse is the portion located on the project site, and is in a degraded state. The east side of the watercourse was enhanced by Sound Transit as part of Link Light Rail construction. Proposed installation of native species cuttings and hydro seed within the areas to be directly disturbed, along with removal of invasive species plants, and the addition of 20 conifer trees to the buffer area will restore the watercourse buffer to an enhanced state. c. Channel, bank and buffer areas replanted with native vegetation that improves the original in species diversity and density; The existing stream buffer condition is degraded due to the presence of invasive species within the project area. Buffer area enhancement, including invasive species management and native plantings to enhance the area around the watercourse will provide an improvement over original species diversity and density. d. Stream channel bed and biofiltration systems equivalent to (in the case of public drainage maintenance projects) and better than in the original stream (in the case of other kinds of projects); There are not proposed alterations to the stream channel bed as part of this project. All impacts and mitigation will occur within the stream buffer. e. Original fish and wildlife habitat enhanced unless technically not feasible. The watercourse buffer will be enhanced with native species plantings. This will improve wildlife habitat over existing conditions. COMMENTS A Notice of Application was mailed on June 9, 2014 to the applicant and to departments and agencies with jurisdiction pursuant to TMC 18.104.090, and to property owners and tenants within 500 feet of the project site pursuant to 18.104.120. The site was posted on June 9, 2014 pursuant to TMC 18.104.110. One comment letter on the project, from Mrs. Thelma Davis, was submitted to the City of Tukwila during the Notice of Application period. A copy of Mrs. Davis' letter is attached, along with responses to comments from both the applicant and the City. Page 6 of 7 CONCLUSIONS 1. New surface water discharges to sensitive areas or their buffers from detention facilities or other surface water management structures is permitted subject to the clean water standards of 1 RCW 90.48 and WAC 173.200 and 173.201, and provided the discharge does not adversely affect water level fluctuations in the wetland or adversely affect watercourse habitat and watercourse flow conditions relative to the existing rate. 2. The applicant has demonstrated compliance with mitigation sequencing. 3. The area of permanent buffer impacts is being mitigated at a ratio that is greater than 1:1 and the entire buffer area restored and enhanced to better than pre -project conditions through the addition of 20 conifer }trees. 4. The applicant has submitted a site plan showing how the new home on Lot 7 will be configured on the lot so as not to encroach within the wetland and stream buffer areas. Per TMC18.45.080 E, the Director may waive buffer setback requirements when a site plan demonstrates there will be no impacts to the buffer from construction or occasional maintenance activities. 5. In order that the new trees and cuttings are able to thrive within the restored buffer areas, a condition of approval of this permit is that the specifications on Sheet 3 of 3 of the mitigation plan be modified according to redlined mark-ups in the attached sheets of the mitigation plan to (1) include removal of roots of invasive plants in the immediate tree planting areas prior to planting; and (2) to change the language of the Container Tree Planting Detail from "do not disturb root ball" to "loosen root ball and prune any circling roots prior to planting". 6. Additionally, one sign per lot that complies with TMC 18.45.060 shall be placed on the fence to ensure future homeowners are aware of the presence of sensitive areas located on their properties, and to promote stewardship of these areas. RECOMMENDATIONS Staff recommends approval of the Special Permission permit for work within wetland and stream buffers, and for a reduction in the buffer setback width, with the following conditions: 1. Sheet 3 of 3, Specification 2. Add: "Roots of invasive plants in the immediate tree planting areas shall be removed prior to planting." 2. Sheet 3 of 3, Container Tree Planting Detail. Change language that states "do not disturb rootball" to "loosen root ball and prune any circling roots prior to planting". 3. One sign per lot that complies with TMC 18.45.060.6 shall be placed on the fence separating the homes from buffer areas. ATTACHMENTS: a.

Tukwila, WA 98168 Re: Comments submitted during the Notice of Application period for the Macadam Short Plat (Short Plat L13-029, Special Permission L14-0001, and Project File PL13-0028) Dear Mrs. Davis, Thank you for submitting your comment letter, dated June 20, 2014 on the Macadam Short Plat project. Multiple departments within the City, including Public Works, Fire, Building, and Planning, are reviewing the permits above. The City has code requirements to address many of the issues raised in your letter. I've coordinated with the Public Works Department to include the information below related to your concerns. The City's responses are grouped into different categories based on the comments you submitted. Storm Drainage and Slope Stability The applicant has submitted a storm drainage analysis and plan for the project, as well as a geotechnical report to assess slope stability. Along the portion of project site adjacent to Macadam Road, "The runoff from the west will be collected by the new curb and gutter that is proposed for Macadam Road and will be piped directly into the wetland/stream along the eastern property line" (p. 15, Macadam Short Plat Technical Information Report). There is a large detention system designed as part of the project which will collect the storm water from the new sidewalk and adjacent roadway area. The storm water from the road and the sidewalk will be released from the detention system into the wetland at a rate that maintains the site's pre -development rate of flow. This drainage system should have the effect of reducing the amount of storm water that flows onto your property. The location of the catch basin at the north side of the sidewalk shown on Sheet 3 of 7, and the location of the pipes connecting from the new lots to the drainage system is conceptual at this time. These will be reviewed in more detail as part of the Public Works construction permit to determine the location that will best capture the runoff from the new sidewalk and the adjacent area of Macadam Rd S and for gravity flow from individual lots to the private drainage system. Street and onsite infrastructure will be constructed per City standards, 2009 King County Surface Design Manual, and Geotechnical Reports and recommendations. Driveways and a portion of Macadam r - Road will collect in a storm drainage system and be retained prior to discharging to an outlet at the northeastern corner of the project site. Curb, gutter, and sidewalk will be constructed along Macadam Road. New catch basins within the street will collect the surface water and flow into the new Public storm drainage system. Future houses will be built close to Macadam Road per Geotechnical Reports and recommendations House roof drains will be connected to a Private storm drainage system and meet the 2009 King County Surface Design Manual requirements. Water quality will be provided as applicable under the 2009 King County Surface Design Manual. Civil plan sheet 3 by Azure Green Consultants is a preliminary Road and Storm Improvements design as part of Preliminary Short Plat number L13-029. The final storm drainage design and construction will be part of a1future Public Works permit. The houses will be constructed as part of future Building permits. Please contact David McPherson at (206) 431-2448 if you have any questions regarding storm drainage and slope stability. Trees and foliage on the project site Trees located along the north side of the project site adjacent to your property line are located within areas mapped as steep slope sensitive areas. Trees located further to the east are located within steep slope and stream buffer areas. Proposed tree removals within sensitive areas require a tree removal permit and planting of replacement trees. Trees that are not located within sensitive areas are those along the street frontage of Macadam Rd. S. Up to four significant trees may be removed for construction of the project, and removal of additional trees not located in sensitive areas may be approved if necessary for construction of the sidewalk and/or utilities. We will work with the applicant as part of review of the short plat to determine whether any trees on the project site will need to be removed. We will also work with the applicant as part of short plat review to determine whether trimming portions of the tree on your property that hang over the property line will be necessary. Parking Part of the City's review of the short plat includes making sure the project meets the parking requirements of the Tukwila Municipal Code (TMC). At least two parking spaces will be required for each new home. New homes often have two -car garages with additional paved area outside the garage for extra parking. Parking is not allowed in the right-of-way of Macadam Rd. S. In the event that any vehicles are parked in the right-of-way or on your property, they would be subject to enforcement. Additionally, one of the erosion control measures identified in the applicant's Erosion and Sediment Control Analysis is construction of an on-site temporary construction entrance and construction parking area (Macadam Short Plat Technical Information Report, page 22). Fire and Home Spacing Concerns On page 4 of your letter, you write that you're concerned about the potential for the houses to be within 10-20 feet of each other for two reasons (1) fire hazards, and (2) potential for noise. The side yard setback requirement on each lot is 5 feet, so the minimum amount of space between the homes will be 10 feet. This requirement applies to all development within the LDR zoning district, and this setback standard has been in place for some time. Since 2011, all new single-family homes are required to have an automatic sprinkler system. Project plans and building permits will be reviewed by the Fire Department for compliance with fire code requirements. The minimum lot size in the LDR zone is 6,500 square feet. The lots proposed with this short plat meet the minimum lot size requirement; lot sizes shown on plan sheets range from 7,070 to 15,205 square feet. The minimum loft width in the LDR zone is 50 feet, and the proposed lots also meet this requirement. The developable area of some of the lots are impacted due to the location of sensitive areas; however, the project is being reviewed for potential impacts to sensitive areas and proposed mitigation measures as part of the Special Permission Permit. The geotechnical report contains information on soil and slope stability, and is used to determine the areas on each lot that are best suited to the development proposed, or measures that must be taken in order for a lot to be buildable. Requests Your requests to receive a two-week notification prior to the start of construction, to have construction of the project start with Lot 1, and to limit the hours of construction to Monday through Friday between the hours of 8:00 a.m. and 5:00 p.m. are outside of what the City can require of the developer. The City limits construction noise to the hours of 7:00 a.m. to 10:00 p.m. Monday through Friday and 8:00 a.m. to 10:00 p.m. on Saturday, Sunday, and State -recognized holidays. Attached is the developer's letter in response to your comments and requests. You will receive a copy of the City's decisions on the Special Permission and Short Plat permits. Please contact me at (206) 431-3659 or Jaimie.Reavis@TukwilaWa.gov with any additional comments or questions.

Davis 13806 Macadam Rd.$ Tukwila, WA June 20, 2014 $i (of- '- - 00 l o hyo (— 077 10 --2(b v4- -2 7 .4s3 -c?S Thank you for meeting with me and my sister, Donna Morris, on June 12th regarding the project site. The major issue I have with the proposed project is regarding the "project site" is water drainage. A. Background My property is located at 13806 Macadam Rd and adjacent to the project site. It is North of project site and is currently at a lower elevation than the project site. Since the project site was filled in and the construction of the 3 houses on the opposite side of Macadam Rd, I have had to deal with a lot of surface water running down across the road and onto my property causing me to have a wet basement. I have had a lot of expense from water draining onto my property. When the land above the road is saturated with water and it rains, water has no place to go except on my property since the City has not put in any storm drains nor changed the road to have it drain into a ditch on the opposite side of Macadam Road. In the 1980's an old barn (See attachment, Photo copy #1) and a small pond were on the project site. The area was at a lower elevation than my property. I never had any problems with water draining from the project site nor the road. The prior landowner of the project site in his anticipation of a subdivision into 7 lots and constructing seven houses, had material dumped to raise the level. My husband (deceased) and I watched many of the loads of material being dumped. There was concrete, roofing material, dirt, rocks, etc. On the south end of the "site" the fire department caught barrels being dumped which required "hazmat" removal. That only 1 of 5 raises a question as to whether other barrels had been dumped at the "site" and were not previously discovered. Additionally, we never saw the bam removed, so it is unknown if it contained anything inside of it as it was presumably crushed from the weight of the material dumped on top of it. Although, there has been some environmental testing of soil samples, it might behoove the city to require additional testing of soil at deeper levels at random locations. Not long after the project site was mounded up, we had a mud slide from that 'mountain of dirt" made by prior landowner. The mud damaged our fence and came halfway to the house (See attachment, photo copies # 2&3). In the past few years, since the construction of the 3 houses across Macadam Rd, I have had to contact the fire department regarding the water running down from Macadam Rd. The firemen looked to see where the water was coming from and they found that a storm drain had been constructed higher than Macadam Rd further south and that a steady stream flowing from the hillside and across Macadam causing the water to flow over into the corner of my property which ran down like a waterfall. As the city is aware, the hillside across Macadam Rd contains a lot of water from the springs in the hillside. The ground becomes saturated from the springs and when it rains, the problem is compounded and surface water drains across Macadam Rd and onto my property. Storm drains are badly needed. B. Drainage of surface water from Macadam Road and Project Site Reading plat maps is not an easy task for a layman and therefore not absolutely sure about our interpretations. In review of the plans for the project site, it appears they have drains planned In another drawing, it shows drains but appears to just end with water draining down the hillside and that is not acceptable. In further review of the plat maps/drawings, in particular Lot #1 - Macadam Short Plat #S3, it appears that there is to be a leader to connect roof and driveway drainage to a pipe that is to run to a storm drain that will ultimately drain the water to the proposed wetland area. However, Lots 1&2, especially Lot #1 would need to be filled to raise the level of the drain line to ensure water will be flowing down to the storm drain that is currently at the top, water does not flow uphill. The plat maps are not clear as to what is going to happen on proposed Lots #1 & 2. It appears that Lot #1 will be entirely on the slope next to my property. Will the trees and other foliage be removed, more fill be added to raise the level of that lot to that of the other lots? If so, will a retaining wall must be built to hold the dirt back from my property. If not, what will be done to ensure that water drainage during rain and lawn watering will not run down on my property? How will the dirt, etc be held back during the excavation and construction phases? Water running off the Tots above will most likely contain contaminates from engine oil and coolants from vehicles which will contaminate all soil below it along with the proposed wetland area. 2 of 5 We were told the project site will have curbing, this will only mean that water from the street will run around the comer and down on my property. As shown in S3 Short Plat, it appears that the pavement and sidewalk would end at the end or at the edge of the project site. This will cause water to become a waterfall on my property during prolonged and/or heavy rain. Water flowing along the curb on the project site would need to be diverted through a pipe to the wetland area or sewer since there are no storm drains along Macadam Road to handle the surface water. C. Trees and foliage on Project Site: The trees that are currently growing on the hillside area designated as Lot #1 are "volunteer" trees. No trees were growing prior to the mudslide as can be seen in attached photo copies #1-3. The trees drop leaves and limbs and blackberry vines also grow in the ditch that was made along the outside of my fence to carry surface water from the road away from my property. The ditch was done by the city or prior landowner of the project site quite some time ago and needs to be cleaned out. - Some trees are quite large and tall enough that if they were blown down during heavy windstorm, the could fall into my house. Also would construction cause some of the large trees to fall towards my house? - Removal of small trees and other vegetation could cause the soil to become loose and therefore a mud/dirt slide. I do not want another mud slide like occurred in 1985. - Blackberry vines are very invasive and I do not want them on my property. Who will maintain the area to prevent the vines from growing and spreading to my property? - Who will ensure the trees do not become so tall that they will fall over damaging my property? My house is on the Tukwila Historical Society listing of historical homes and therefore, should be protected and not be damaged by falling trees and mudslides. The landowner and City must address my concerns regarding surface water and drainage along with the large trees to prevent further damage to my property. It would be negligent to not address the concems about the debris that was dumped at the project site and to allow water containing contaminates to be dumped onto adjacent landowners causing damage to their homes. 3 of 5 D. Parking Parking will need to be addressed. Will there be sufficient parking for at least 2 vehicles without anyone having to park on the road? If a family has one or two teenagers who drive, that will increase the number of vehicles in their driveway. I would like to be able to get to the mailbox without having to work my way around parked vehicles blocking the gate and path to the mailbox. I have problems with walking on uneven surfaces and do not wish to fall because someone parked a car in a manner that causes me to step into a hole. Also, parking in front of my house would hamper mail delivery and emergency vehicles since there are no curbs to paint to tell people not to park there. I am assuming that the houses are to be "single family homes" and not ones that will contain multiple family members, parents, kids, grand parents, aunts, uncles and cousins, etc. Multiple family members will impact the number of vehicles. I already have neighbors with multiple family members and about 12 vehicles parked all over and some those vehicles seem to never be moved. I realize the current landowner is wanting to make a quick turnaround and gain the most profit. I realize that they are in it to make money from their investment. However, their profit should not cause harm to the neighboring properties since it will only devalue his properties in the end. It is my opinion that seven homes on the project site is too many. - Proposed Lot #1 is not a good building site as it stands. It is a hillside full of trees and other foliage that would need removal. Any drain lines connecting to a storm drain at the top of the hill will fail since water does not flow up hill. The only way it could be made into a proper building site is to build a retaining wall and fill the area to raise it to the same level as the other proposed lots. You should take a good look at this area before a decision is made about the subdivision and approval of any building permits. - Houses within 10-20 feet of each other is a fire hazard. If one catches fire, it will quickly spread to the others. - Houses placed so close only make unhappy homeowners since they will hear noises from the next house. 4 of 5 E. Requests I do want to receive a copy of the City's decision on the project. If the project is approved, I ask that the landowner or person in charge of construction to give me a 2 week notice of the beginning of the construction and an estimate of the length of the construction. Since construction is quite noisy and my health requires me to have adequate rest, I also request that: - I know my mimmosa tree is quite Targe and a limb may be over the fence and may need to be trimmed back. I ask that the tree not be damaged during construction. The tree is quite old and the tree means a lot to me as my father gave me the tree. When the tree blooms, it is a huge pink umbrella. - construction be done Monday through Friday, between the hours of 8:00 am and 5:00 pm. - the construction begin on the site designated as Lot #1 on the plans, closest to my property so that the house can help buffer some of the noise from the construction of the other houses and that Lot 7 be the last to be constructed. - Additionally, I ask that the construction crew not block the area in front of my gate to allow for emergency vehicles should I need one. I pray there will not be such a need. Thank you for your consideration of my concerns about the proposed project. I am not opposed to having good neighbors.

Two wetlands (Wetlands A and B) were identified and delineated in the northeastern and southeastern portions of the site during the field investigations and subsequently surveyed (Figure 1). On March 28, 2013 we conducted a site meeting to review the wetland delineation and classification with Sandra Whiting, City of Tukwila Urban Environmentalist. The wetland delineation and standard buffers as depicted on Figure 1 were preliminarily approved by Sandra during this meeting. Also during this site visit the ordinary high water of the stream located to the east of the property was mapped and is depicted on Figure 1. Attachment A contains data sheets prepared for representative locations in both the upland and wetland. These data sheets document the vegetation, soils, and hydrology information that aided in the wetland boundary delineation. 2.0 EXISTING CONDITIONS 2.1 Wetland A Wetland A is located in the northeastern corner of the site and consists of a Slope Hydrogeomorphic Class containing a Palustrine Emergent plant community dominated by reed canarygrass (Phalaris arundinacea). At the time of the field investigations soils within the wetland were generally saturated to the surface. Fred Herber March 24, 2014 Page 2 Runoff within the wetland appears to infiltrate and is separated from the off-site stream by a small berm. Wetland A meets the criteria for a Category IV wetland (Attachment B) and requires a standard 50 -foot buffer plus 10 -foot building setback per TMC 18.45.080.D. 2.2 Wetland B and Off -Site Stream Wetland B is located in the southeastern corner of the site and also consists of a Slope Hydrogeomorphic Class. Vegetation within Wetland B consisted of a small Palustrine Forested plant community that contained a canopy of red alder (Alnus rubra) with an understory of red elderberry (Sambucus racemosa), Indian plum (Oemleria cerasiformis), and rose (Rosa sp.). Groundcover was dominated by reed canarygrass. Soils within the wetland were generally saturated to the surface and runoff drains east directly into the off-site stream. This stream flows from south to north along the east side of a chain link fence located under the Sound Transit rail line. It is my understanding that native plantings along the riparian corridor of the stream were installed as mitigation associated with construction of the rail line. Wetland B meets the criteria for a Category IV wetland (Attachment B) and requires a standard 50 -foot buffer plus 10 -foot building setback per TMC 18.45.080.D. The off-site stream has been classified by the City as a Type 3 (Np) watercourse and requires a standard 80 -foot buffer plus 10 -foot structure setback from the ordinary high water of the stream per TMC 18.45.100.C. 3.0 Proposed Project Impacts The proposed Macadam Short Plat has been designed to avoid all permanent impacts to the sensitive areas and their buffers. The only work that must occur within the buffer is the installation of an above -ground stormwater conveyance pipe and associated dispersion pad along the slope in the northeastern portion of the site. This pipe would be installed within a Jleavily disturbed portion of the buffer and would be_designed.to-. avoid any significant native;vegetat n. ft is my understanding that a stormwater fiftra-tion system has been designed by Azure/Green Consultants LLC that would also treat all collected stormwater runoff prior to release into the wetland. A 6 -foot tall solid wooden fence is proposed along the edge of the buffer to clearly identify the edge of the protected area. Gates within this fence could be installed as necessary to allow access to individual lots for limited maintenance and pedestrian access. All temporary buffer impacts associated with the installation would be restored following construction. In addition, a mitigation plan has been prepared (see Section 4 below) to increase the habitat value of the buffer over current conditions. Fred Herber March 24, 2014 Page 3 3.1 Structure Setback Reduction for Lot 7 As part of the proposed project, the standard 10 -foot structure setback on Lot 7 would be reduced to 5 feet. This 5 -foot setback would continue to allow maintenance access around the back of the residence, with additional maintenance access provided along the south side of the residence. Since a 6 -foot wooden fence would be installed along the edge of the buffer, there should be no intrusion into the wetland buffer as part of the proposed structure setback reduction. 4.0 Proposed Proiect Mitigation Mitigation for the minor buffer impacts associated with installation of the stormwater conveyance line would occur through: 1) planting of black twinberry (Lonicera involucrata) cuttings along the outfall pad, 2) mowing patches of monotypic blackberry, within the buffer and 3) planting 20 native conifer trees scattered throughout the mowed monotypic blackberry patches (Figures 1 through 3). It was determined that planting conifers scattered throughout the buffer would provide for a greater increase in habitat value of the overall buffer than planting native species within the narrow strip adjacent the proposed stormwater conveyance pipe. 4.1 Goal, Objectives, and Performance Standards for Enhancement Area The primary goal of the enhancement plan is to increase the habitat value of the buffer over current conditions. To meet this goal, the following objective and performance standard has been incorporated into the design of the plan: Objective A: Replace invasive species with native trees and shrubs. Performance Standard: There will be 100% survival of all woody planted species throughout the enhancement area at the end of the first year of planting. Following Year 1, success will be based on an 80% survival rate of all initially planted tree and shrub species or equivalent replacement of a combination of planted and recolonized native species. 4.2 Construction Management Prior to commencement of any work in the enhancement area, the clearing limits will be staked and any existing vegetation to be saved will be clearly marked. A pre - construction meeting will be held at the site to review and discuss all aspects of the project with the landscape contractor and/or the owner. A consultant will supervise plan implementation during construction to ensure that objectives and specifications of the enhancement plan are met. Any necessary significant modifications to the design that occur as a result of unforeseen site conditions will be jointly approved by the City of Tukwila and the consultant prior to their implementation. 4.3 Monitoring Methodology The monitoring program will be conducted for a period of five years, with the submittal of annual reports. Fred Herber March 24, 2014 Page 4 Photo -points will be established from which photographs will be taken throughout the monitoring period. These photographs will document general appearance and progress in plant community establishment in the enhancement area. Review of the photos over time will provide a visual representation of success of the enhancement plan. 4.4 Maintenance Plan Maintenance will be conducted on a routine, year round basis. Additional maintenance needs will be identified and addressed following periodic maintenance reviews. Contingency measures and remedial action on the site shall be implemented on an as -needed basis at the direction of the consultant or the owner. Routine maintenance of planted trees shall be performed. Measures include resetting plants to proper grades and upright positions. Tall grasses and other competitive weeds shall be weeded at the base of plants to prevent engulfment. Woody plants shall only be pruned at the direction of the consultant or to remove pest infestations. 4.5 Contingency Plan All dead plants will be replaced with the same species or an approved substitute species that meets the goal of the enhancement plan. Plant material shall meet the same specifications as originally -installed material. Replanting will not occur until after reason for failure has been identified (e.g., moisture regime, poor plant stock, disease, shade/sun conditions, wildlife damage, etc.). Replanting shall be completed under the direction of the consultant, City of Tukwila, or the owner. 4.6 As -Built Plan Following completion of construction activities, an as -built plan for the enhancement area will be provided to the City of Tukwila. The plan will identify and describe any changes in relation to the original approved plan. If you have any questions, please give me a call.

At the meeting I indicated that I would follow up with you regarding your proposal for lot seven to reduce the setback from the buffer from ten feet to five feet. The required buffers for both the wetland and stream would remain unchanged. The City is fine moving ahead with this proposal, provided some additional items are submitted to the City as part of the short plat review. Please provide a conceptual home site plan and floor plan for proposed lot #7. As we discussed yesterday, one of the concerns that the City has is the ability to construct a house on lot #7 that can meet the fire egress requirements. This issue might be able to be solved by having the required bedroom egress windows on the front of the house. Please note that the Fire Department will have to review and approve the floor plan and if a house cannot be constructed on lot #7 that meets these, or other standards, the City will not allow this lot be created. Also, to reduce the chances of the buffer being disturbed, the City would like to see a six foot tall fence constructed along the rear of all the lots proposed with this short plat. I think the design that Fred proposed yesterday would be a good fit. Please update your plans to show the location and design of the fence. We also discussed the stormwater line on lot #1. As Sandra discussed in the meeting, before the water is discharged into the sensitive area it must meet water quality standards. Please update your plans to reflect this requirement. Also, please update the plans to show cedar plantings throughout the buffer area. I think this email provides the next steps in moving forward. Please let me know if you have any questions.

What you have proposed would not be permitted by code. The City cannot create a lot through a platting process that would require a variance in order to meet minimum setback requirements. I would like to suggest that you look at the Planned Residential Development (PRD) standards. Perhaps the PRD standards could be used to provide some flexibility in the lot design. I have attached the applicable code language. Regards, Brandon J.

From: Jim Job Sent: Monday, February 03, 2014 10:04 AM To: 'Brandon Miles' Cc: Fred Herber; 'john@altoliver.com' Subject: RE: Macadam Road Short Plat Hi Brandon, Here is another idea for lot 7. What if we propose a reduced wetland buffer building setback to 5 feet so there is room for maintenance of the house and the fence on the buffer line? Then we would also apply for a variance for a front yard setback reduction to the house portion of the structure only, leaving the setback at the garage at 20 feet but using a 10 - foot setback on the house. Please see the attached exhibit. This quick sketch nets us 384 sq feet in the garage, 494 square feet of living area on the first floor, and roughly 900 square feet on the second floor. 1 We can get a yard area on the side and a patio there for entertaining. The green hatching did not work out like I wanted but I think you get the idea. We would have a reasonable area on the side of the house for kids and pets. We would still not be proposing any mitigation here since we are just reducing the building setback to the buffer. We would not have any impact to the wetland/stream buffers. Please let me know if this is an idea you think you can support. If it is, we can prepare a variance package for the front yard setback reduction to go along with the special permissions we submitted for the reduced wetland/stream buffer building setback.

Sandra is just one person of a team who has to review land use applications. In order to ensure that we have proper communication please direct any submissions to me. That way I can make sure they get routed to the proper Departments. Furthermore, please cc me on emails with the City regarding this project. You are welcome to talk with subject matter experts. Letting me know that these discussions are taking place ensures that the project is moving forward. Best Regards, Go Seahawks! Brandon J.

There were 4 sheets of wetland mitigation for our storm outfall and our proposed layout. We are not sure if John Altman submitted this or if Sandra have ever reviewed it. Can you let us know the status on this. One we work the outfall location out and the Lot 7 2 concerns, we can finish the engineering and get this project into construction.

I have no idea exactly what is being requesting in the application. Cleary, you are requesting to install a stormwater discharge pipe within the buffer area; however, it is unclear what is being proposed for lot seven. The application checklist asks for a "written description of the project, the deviation or approval being requested and response to the applicable decision criteria." I am not so concerned with having this for the stormwater pipe, but something needs to be provided. Providing an email chain doesn't do the job. Please provide a specific narrative of what exactly is being proposed on lot seven. In your narrative please also provide a response to the applicable criteria (see attached). The City still has concerns regarding lot seven and the ability to have a house fit on the property. As currently shown, it appears the house would have a very small backyard. Furthermore, if the buffer setback is reduced it is unclear how maintenance activities to the house would be accomplished. I also need to know how many trees are going to be removed in order to place the stormwater pipe. Thanks, Brandon Go Seahawks! Brandon J.

The short plat application was subsequently deemed completed in an email dated June 26, 2013. City staff, composed of representatives of the Departments of Community Development, Fire, and Public Works, has completed review of the short plat application. Additional information is needed prior to preliminary approval being granted for the short plat application. Please note that these comments are major substantive comments regarding the short plat application. Minor required edits and notes to be added to the short plat will eventually be provided, once the issues outlined below are addressed. Sensitive Area Impacts As you are aware, the project site contains two category IV wetlands as defined by Tukwila Municipal Code (TMC) 18.45.080 (B) (4). Additionally, there is an offsite type 3 watercourse as defined by TMC 18.45.100 (C). Category IV wetlands are required to have a 50 foot buffer and a ten foot setback from the buffer for all residential structures (TMC 18.45.080(D) and (E)). The type 3 watercourse is required to have an 80 -foot buffer and a ten foot setback from the buffer for all residential structures (TMC 18.45.100 (C) and (D)). The "Critical Areas Map" included in the "Macadam Short Plat, Sensitive Area Study (hereinafter "Sensitive Area Study")," prepared by Altmann Oliver Associates, LLC shows the locations of the wetlands, streams, buffers, and respective setbacks. As shown on this map, all of the lots of the proposed short plat will include a large wetland buffer on their individual lots. Furthermore, a stormwater conveyance system is proposed to be discharged into the buffer area. A note is provided on the plans that states, "All Temporary Buffer Impacts to Be Restored." The proposed work within the buffer area and the short plat application itself is inconsistent with TMC 18.45 "Environmentally Sensitive Areas". First, discharging the surface water into the buffer area of the stream and/or wetland buffer is only permitted with Special Permission of the Director and then only with mitigation, including enhancement of the buffer area (TMC 18.45.070 (B)). Simply restoring the buffer area to pre -project conditions is insufficient in meeting the requirements of TMC 18.45.070 (B). Finally, proposed lot seven of the short plat, as shown on the survey documents, is severely constrained by the required sensitive area buffer and associated setback. When the required structure setbacks of TMC 18.10 are applied to proposed lot seven the lot appears to be unbuildable. If your intent is to request a buffer reduction then that application must be submitted and reviewed with the pending short plat application. Please note that the City may not approve proposed lot seven, but instead may require that the lot area be merged with proposed lot six (TMC 17.20.030). The City's decision will largely be influenced on the quality and scope of the enhancement plan submitted to the City. Corrective Action Required: Submit a Special Permission Application, which would include a revise Sensitive Area Study and mitigation plan, including a planting plan. Landscaping Plats of five or more Tots are required to have one tree planted in the front yard (TMC 17.20.030 (G)). Credit can be given for retaining any existing trees in the front yard area. Corrective Action Required: Provide a plan that outlines how the one tree requirement will be met. Emphasis should be placed, where possible on retaining existing trees. Public Works Comments The following comments from the City's Public Works Department need to be addressed prior to a decision on the short plat application. Corrective Action Required: Provide a Traffic Concurrency Certificate Application and pay the required $1,200 fee (see enclosed) Provide a current Sanitary Sewer Availability Certificate from Valley View Sewer District. Provide a current Water Availability Certificate from Water District 125. Update the plans to show all existing utilities being underground or request a waiver from the requirement. Enclosed with this letter are some additional comments from the City's Fire Department. Please note that you do not need to address these additional comments at this time. Fire Comments The following comments from the City's Fire Department need to be addressed prior to a decision on the short plat application. Corrective Action Required: Verify that the required fire flow of 500 GPM can be met for the new project. Page 2 of 3 Next Step As outlined above, the short application submitted for the subject property cannot be approved. Your next step in moving the project forward is to address the comments outlined in this letter and provide a formal correction response to the City. Corrections need to be submitted directly to the Department of Community Development.

All lots will access directly off the existing public road: Macadam Rd. A public storm drainage system will be installed to control runoff rates for the frontage improvements and home construction. Runoff will be collected in catch basins in Macadam and in roof drains on the lots and connected to a detention tank. The detention tank will be sized for duration control to match pre -developed runoff rates. The release will be into an onsite wetland. Topography: The site includes a relatively flat plateau area along the Macadam Rd. frontage. This plateau varies in width from about 90 feet on the north end of the property down to about 40 feet at the south end of the property. From the edge of the plateau the site slopes steeply to the east with average slopes of about 25%. Grade flattens out in the northeast and southeast corners. Based on the geotechnical engineering report prepared by Golder Associates, the site has been filled multiple times over the years and therefore the existing topography is not necessarily natural. The site's topography limits effective development to the plateau area. Ground Cover: The upper plateau area is mainly covered with pasture grass and includes a gravel parking area. The sloped portion of the site is covered with brush and trees. Drainage: The frontage of Macadam Road is currently open drainage and sheet flows runoff onto the site. Runoff follows the topography as described above as sheet flow. In the flat areas at the northeast and southeast corners of the site are existing wetlands. Immediately offsite to the east, within the 1-5 right-of- way, is an existing stream that collects the onsite runoff and drains north. Per the Sensitive Area Study prepared by Altmann Oliver Associates, the stream will have an 80 foot buffer and the two wetlands will each have 50 foot buffers. These buffers effectively eliminate the majority of the slope are from potential development. Soils: Per the Geotechnical Report prepared by Golder Associates the native soils onsite consist of "recessional lacustrine deposits" underlain by "dense to very dense till and stiff glacialacustrine deposits." However, the flat upper area consists primarily of fill with depths ranging from 12 to 27 feet. Based on the soils preset at the site, infiltration of runoff is not feasible and special attention is required for building foundations. See Geotechnical Report for additional information and recommendations. Floodplain Based on the FEMA FIRM map, the site does not include a regulated floodplain.

Storm Drainage Requirements: The project will require overl 9,000 square feet of new impervious area. Therefore, Full Drainage Review is required. Following is a summary of the Core and Special Requirements and how each is addressed: • Core Requirement #1 — Discharge at Natural Location: In existing conditions, runoff sheet flows to the east, with the majority flowing straight into the existing stream just off the east property line. A small portion of onsite runoff flows directly into the two wetlands at the northeast and southeast corners of the site. Each wetland discharges into the stream which flows northerly. The proposed detention facility will release directly into the northeast wetland. While the development will result in some re -direction of runoff, the altered areas are minimal and will have no negative impact on natural flow rates. • Core Requirement #2 — Offsite Analysis: The offsite analysis makes up Section 3 of this report to address this requirement. • Core Requirement #3 — Flow Control: The site is within the City's Southgate Creek Basin, therefore Level 2 Flow Control with Conservation to Forested is required. See Section 4 of this report for Detention Tank sizing. • Core Requirement #4 — Conveyance System: The project will include a closed conveyance system in Macadam Road, a roof drain conveyance pipe, and a detention tank discharge pipe. See Section 5 for conveyance system analysis. • Core Requirement #5 — Erosion & Sediment Control: An Erosion and Sediment Control plan is included with the grading plan in the construction drawings. See Section 8 for additional discussion. • Core Requirement #6 — Maintenance & Operations: The Macadam Road conveyance system, detention tank, and discharge pipe will be owned and operated by the City of Tukwila. The roof drain collection system will be owned and operated by the Homeowners' Association. An Operation and Maintenance Manual will be prepared and submitted for City approval prior to final approval of construction plans. • Core Requirement #7 — Financial Guarantees & Liability A surety bond for 1 50% of the value of the proposed right-of-way work will be required. A financial guarantee for 10% of the project costs for erosion prevention and sediment control may be required. • Core Requirement #8 — Water Quality The project includes 4,346 sf of PGIS. Since this is less than 5,000 sf, the project is exempt from water quality requirements. Macadam Short Plat TIR May 31, 2013 Page 12 of 25 • Special Requirement #1 — Other Adopted Requirements There are no known applicable other adopted requirements for the project. • Special Requirement #2 — Flood Hazard Area Delineation The site does not contain a flood hazard area per the FEMA FIRM map for the site. • Special Requirement #3 — Flood Protection Facilities This project does not include any flood protection facilities. • Special Requirement #4 — Source Control The project does not require a commercial building or commercial site development permit, therefore this requirement does not apply. • Special Requirement #5 — Oil Control This project does not trigger oil control requirements. Sensitive Areas: The site does include wetlands and an adjacent stream. A sensitive area report has been prepared to address these areas with 50 foot wetland and 80 foot stream buffers required. Macadam Short Plat TIR May 31, 2013 Page 13 of 25 Section 3 — Off -Site Analysis During the previous application for development of this parcel, a preliminary drainage plan was designed by Jaeger Engineering in 2000. The associated Drainage Report dated October 20, 2000 included the required off-site analysis. That analysis is still relevant and it does not appear additional analysis is necessary. Therefore, the original off-site analysis is adopted verbatim, with one exception: a shallow ditch with culverts and closed conveyance system exists in Macadam on the opposite side from the site. This system appears to intercept any upstream offsite flows. Therefore, the drainage basin for drainage analysis extends only to the road centerline. Macadam Short Plat TIR May 31, 2013 Page 14 of 25 III. OFFSITE ANALYSIS REVIEW OF RESOURCES The following resources were used in the preparation of this section: 1. King County Wetland Inventory Reports: ' There are no wetlands shown in this report, but small wetlands were field located on the site. 2. King County Surface Water Management Reconnaissance Report shows the beginning of an un -named stream along the eastem edge of the site. 3. Generalized topog. map from the City of Tukwila. 4. King County Sensitive Area Map Folio - Dec.. 1990 ▪ Wetlands: none shown, but field mapped. • Streams and 100 year floodplain: un -named stream, • Erosion Hazard: none on site. • Landslide Hazard: none on site. • Seismic Hazard: none on site. • Coal Mine Hazard: none on site. 5. USGS topography map 6. USDA Soil Conservation Service soils survey. FIELD INSPECTION A visual reconnaissance of the site and the offsite drainage system was performed on Sept 12. The weather was dry. UPSTREAM OFFSITE DRAINAGE CONTRIBUTION There is a rather targe upstream area to the west that drains down onto Macadam Road with some of the runoff extending onto the site and into the stream along the eastern property line. The stream also begins south of the site and travels along the eastem property line, the common line with the freeway right-of-way. The stream will not be altered by this project because the eastern portion of the site will remain undeveloped. The runoff from the west will be collected by the new curb and gutter that is proposed for Macadam Road and will be piped directly into the wetland/stream along the eastern property line. Macadam Short Plat TIR May 31, 2013 Page 15 of 25 DOWNSTREAM DRAINAGE ANALYSIS The site has some minor drainage improvements that include catch basins and piping that was installed as part of the previous grading permit. The catch basins are located along the top edge of the fill and are piped to the lower wetland at the northeast property corner. The stream that runs along the eastern edge of the site and the freeway right-of-way is the primary component of the downstream drainage system. 1. Drainage leaves the site within the stream and travels to the north for approx. 500 ft. This portion of the stream is adjacent to the freeway ROW and flows past the end of S. 138th St. It flows into a wetland area that is approx. 300 ft. north of S. 138th St. This wetland area collects smaller swales coming in from the west and southwest. 2. The wetland area has an outlet to the north. This also is in the form of a stream than flows within a deeper swale. The stream crosses under S. 136th St. at approx. 1000 ft. past the site within a culvert. The stream then continues to the north for approx. 500 ft. and crosses under 48th Ave. S. within a culvert. 3. The stream continues within a network of culvert sections and open ditch sections behind the houses and buildings along the west side of S. 134th Pl. There have been reports of occasional overtopping within sections of this segment of the stream corridor. SUMMARY The downstream drainage from this site will be discharged into the Stream that flows along the western edge of the 1-5 corridor. This is a major drainage channel and continues to be a main drainage corridor until its discharge into the Duwamish River. The stream is well defined and is maintained by the City as necessary. The history of problems along S. 134th PI. is said to be a result of an undersized culvert at the north end of S. 134th PI. If is also said that the problem is cured when this culvert is periodically cleaned. The developed drainage system will include a Level 1 flow control structure and as such, should not have any significant effect on the downstream drainage system. Macadam Short Plat TIR May 31, 2013 Page 16 of 25 it '41 ov`n3nO " 1 _ • Macadam Short Plat May 31, 2013 TIR Page 17 of 25 Section 4 — Flow Control and Water Quality Facility Analysis and Design Part A - Existing Site Hydrology In existing conditions, any runoff travels across the site as sheet flow from west to east. Approximately 0.124 acres of existing pavement drains onto the site from Macadam Road. Runoff sheet flows into the stream immediately offsite to the east as well as directly into wetlands at the northeast and southeast corners. The site soils consist of fill over a till soil. Therefore the soils are modeled as C soils in the WWHM analysis. Existing ground cover consists of pasture on the upper flat area and brush and trees on the existing slope. As required for flow control sizing, pre -developed conditions are modeled as forest; with the exception of the existing paving run-on area, which is modeled as actual coverage, flat road. For the WWHM analysis the run-on area and project area are entered as two basins with the following areas: PRE -DEVELOPED sf acre RUN-ON sf acre C, Forest, Steep 7734 0.178 Road, Flat 5405 0.124 C, Forest, Mod 6079 0.140 C, Forest, Flat 17045 0.391 Total 30858 0.708 1 1 1 I Macadam Short Plat TIR 1 May 31, 2013 Page 18 of 25 Part B - Developed Site Hydrology The project includes widening of Macadam Road with installation of curb, gutter, and sidewalk. Runoff will be collected in the gutter, including existing improvements included in this analysis as run-on, and collected in catch basins and a closed conveyance system that will be routed to a detention tank for flow control. A separate, private onsite collection system will be installed for roof runoff and also tied to the detention tank. Essentially, only the upper flat plateau area will be disturbed as the majority of the slope area is within the stream and/or wetland buffers. This area will continue to sheet flow to the east and is ignored in the hydrologic analysis. The resulting areas for the WWHM analysis are: DEVELOPED sf acre RUN-ON sf acre Road, Flat 1382 0.032 Road, Flat 5405 0.124 Sidewalk, Flat 1786 0.041 Driveway, Flat 3500 0.080 Roof, Flat 12600 0.289 Total Impery 19268 0.442 C, Lawn, Flat 8690 0.199 C, Lawn, Steep 2900 0.067 Total Pery 11590 0.266 Total 30858 0.708 The resulting peak runoff rates are: Flow Frequency Flow(CFS) 2 Year = 0.1549 5 Year = 0.1918 10 Year = 0.2159 25 Year = 0.2464 50 Year = 0.2691 100 Year = 0.2919 1 1 1 1 1 Macadam Short Plat TIR May 31, 2013 Page 19 of 25 Part C — Performance Standards The site is within the City's Southgate Creek Basin, therefore Level 2 Flow Control with Conservation to Forested is required. This requires that the developed release durations do not exceed those of pre - developed conditions from 1/2 of the 2 -year event through the 50 year event, with pre -developed conditions considered as forested. WWHM will be used to calculate flow rates and durations as well as analysis of the proposed detention tank. Part D — Flow Control System WWHM was used to calculated peak runoff rates and flow durations for pre -developed and developed conditions per the parameters above. A 96 -inch diameter detention tank will be used to detain flows to limit the release durations as required. The tank will be located along the front yard area of two lots and run between two lots. Due to the relatively steep natural slope, the discharge pipe will consist of HDPE extending to daylight on the surface of the slope with a release on a rip rap pad at the edge of Wetland A in the northeast portion of the site. This will allow for minimal disturbance of the slope and wetland buffer. The results of the WWHM Analysis can be found in Appendix A. The results show that 164 feet of 96 - inch diameter tank is required to provide the necessary detention volume. See sheet S3 and S5 for storm detention system design and details. Part E — Water Quality System The project includes 4,346 sf of PCIS. Since this is less than 5,000 sf, the project is exempt from water quality requirements. Macadam Short Plat TIR May 31, 2013 Page 20 of 25 Section 5 — Conveyance System Analysis and Design With only 0.153 acres of impervious area draining to the roadway storm system and 0.289 acres of roof to the roof drain system, we feel a detailed storm conveyance system analysis is not warranted. The 12 -inch storm pipe for roadway drainage and 6 -inch pipe for roof drainage are typical of conveyance systems in this area Section 6 — Special Reports and Studies A Sensitive Area Study dated May 14, 2013 was prepared by Altmann Oliver Associates, LLC to address the existing wetlands and stream, required buffers. A Geotechnical Report was originally prepared for the project on March 21, 2002 by Golder Associates. An addendum to this report was prepared on March 29, 2013 by Golder Associates. Section 7 — Other Permits A right-of-way permit will be required for the improvements to Macadam Road. Building permits will be required for the individual residences. Macadam Short Plat TIR May 31, 2013 Page 21 of 25 Section 8 — CSWPPP Analysis and Design Part A — ESC Plan Analysis and Design ESC Measures: 1. Clearing Limits — The clearing limits will be the edge of the wetland and stream buffers plus the area within the buffer needed to install the discharge pipe. Along the buffers, silt fence will provide dual duty as perimeter protection and marking clearing limits. Orange construction fencing will be used to mark clearing limits within the buffer. 2. Cover Measures — Typical options for cover include plastic sheeting, mulch, and jute mat. All are appropriate options for this project and should be chosen at the contractor's discretion. 3. Perimeter Protection — Silt fence will be used at the edge of the wetland and stream buffers both to provide perimeter protection and mdrk clearing limits. Silt fence will wrap around the north end of the grading limits as well. 4. Traffic Area Stabilization — A temporary construction entrance and construction parking area will be created onsite. 5. Sediment retention — due to the limited scope of the project, the silt fence as perimeter protection is also adequate for sediment retention. 6. Surface Water Collection — due to the limited scope of the project, surface water collection is not necessary. Runoff should be allowed to sheet flow through the silt fence to avoid concentration of runoff. 7. Dewatering control — Per the Geotechnical Report for the site, seepage was not typically encountered at the expected depths of excavation required for this project. 8. Dust Control — Periodic watering of the site will be required to provide dust control. 9. Flow Control — Due to the limited scope of the project, flow control is not necessary as part of the ESC facilities. Part B — SWPPS Plan Sheet S4 of the construction drawings show the required ESC BMP's and applicable notes.

Golder Associates May 2, 2013 Fred Herber High Country Homes PO Box 188 Puyallup, WA 98371 RE: GEOTECHNICAL REPORT ADDENDUM MACADAM ROAD SOUTH RESIDENTIAL PLAT TUKWILA, WASHINGTON Dear Mr. Herber: Project No. 13-00007.000 RECEIVED JUN 13 2013 REC'1IC® f .�, Y AIN 2 5 2013 DEVELOPMENT TUK�LI PUBLIC W,RKS Golder Associates Inc. (Golder) is pleased to provide this addendum report to High Country Homes for a proposed residential housing plat located due south of South 138th St along Macadam Road in Tukwila, Washington (subject property). Golder completed a geotechnical report for the subject property titled Geotechnical Design Report: Macadam Road South Residential Plat, Tukwila, Washington dated March 21, 2002. The report was for a proposed residential development that consisted of seven single family homes. We understand that High Country Homes has secured the rights to the report and the property and is proposing slight modifications to the plat design and requested an update of our 2002 report. The scope of this addendum was completed in accordance with our Proposal No. P1300007 dated March 21, 2013 and was based on discussions with Mr. Fred Herber on March 19, 2013. 1.0 BACKGROUND AND PURPOSE In March of 2002 Golder completed a geotechnical site investigation and provided foundation design recommendations for construction of a seven lot single family residential development at the subject property. A copy of Golder's 2002 report is included in Appendix A. The property consists of an approximate 1.58 -acre lot (Job 2013) located between Interstate 5 (1-5) and Macadam Road in Tukwila. Site elevation ranges from approximately 128 feet above mean sea level (MSL) at the portion of the property adjacent to Macadam Road to about 96 feet above MSL in the northeast corner of the property adjacent to 1-5 (Job 2013). The approximate western half of the property is graded level adjacent to Macadam Road before sloping downward towards 1-5 and includes a small area covered with gravel. The 2002 geotechnical investigation included eight test pits (TP -1 through TP -8) and three borings (GB -1 through GB -3). Results of the subsurface investigation identified up to 27 feet of fill materials onsite. Recommendations were provided in our report for supporting the house foundations on augercast piles that extended through the fill and into the native soil below. During our 2002 investigation we identified evidence of a shallow scarp from a slump along the eastern facing fill slope on the property. The slump was described as occurring approximately in the late 1980's and then was covered or filled back in with fill. The purpose of this addendum report is to provide an update of the seismic code recommendations, and discuss any changes that we observed on the site that would result in any changes to the recommendations contained in our 2002 report. The current site development plans are preliminary but appear to closely match the 2002 development plans. The number of lots will remain the same but we have not been furnished with a grading or foundation plan for this report. 050113jawtl report addendum.docx Golder Associates Inc. 18300 NE Union Hill Road, Suite 200 Redmond, WA 98052 USA Tel: (425) 883-0777 Fax: (425) 882-5498 www.golder.com Golder Associates: Operations in Africa, Asia, Australasia, Europe, North America and South America Golder, Golder Associates and the GA globe design are trademarks of Golder Associates Corporation Fred Herber May 2, 2013 High Country Homes 2 13-00007.000 2.0 DATA REVIEW Golder reviewed the Washington State Geologic Information Portal and the Department of Ecology Well Log Database for any geologic information on the site since 2002. No new information was found on the databases. During our site visit we observed a vertical 5 -inch diameter PVC casing with a cap at the northwest corner of the property. The purpose of the casing is unknown. We searched the well log database for any record of a monitoring well being installed on the subject property but no wells were recorded. 3.0 SITE RECONNAISSANCE A site reconnaissance of the subject property was performed by a Golder geotechnical engineer on March 25, 2013 to observe any changes in site conditions since our 2002 report. We observed the area of the scarp described in the 2002 report, the remaining slopes and the upland portion of the site. Currently the property contains a small gravel parking area to the south adjacent to Macadam Road. To the north of the gravel parking area, the lot is lightly vegetated with grass. Some of the upland area is rutted out due to off-road vehicles. Drainage within this rutted area is poor and as a result the ground surface is soft. The northern and eastern crest and subsequent slopes are vegetated with blackberry and young Alder trees. The northern boundary of the site slopes downward toward the northeast from Macadam Road. The northern boundary is separated by a chain link fence from the adjacent property. The ground surface between the chain link fence and the toe of the fill slope was saturated with some areas of standing water. Sand bags were stacked along the base of the chain link fence likely to prevent water from draining into the adjacent property. An area of standing water was observed along the northeastern corner of the property. The eastern boundary of the property borders the elevated track of the King County Link Light Rail (light rail) from Seattle -Tacoma International Airport. The light rail maintains an easement adjacent to the property which extends along the toe of the fill embankment. The easement is landscaped with small shrubs and trees on a moderate eastern sloping face. The easement is sloped to drain surface water into a ditch that is oriented parallel with the centerline of the light rail. The ditch is lined with cobbles and is outside of the property boundary. A chain link fence exists adjacent to the light rail and the subject property. The slopes are heavily vegetated with grass, blackberry and young trees. The crest of the fill slope embankment did not display any obvious signs of displacement as noted previously in our 2002 report. The slope was heavily vegetated and there were no signs of recent slumps or slope movement. Due to the thickness of the vegetation it is possible that surface erosion or small scale slumps may be obscured. However, if they occur they would be small and unlikely to have a significant impact on the overall slope stability. In our opinion, the slope conditions appear relatively unchanged since our 2002 investigation. 4.0 SEISMIC DESIGN This section provides updated seismic design parameters that supersede those in our 2002 report. The 2009 Seattle Building Code (SBC) is available online and was referenced on March 26, 2013 for seismic site class designation determination (http://ecodes.biz/ecodes support/free resources/Seattle2009/ 09seattle building/09seattle building main.htm). The seismic design section provides information to be used as a basis for seismic design of structures. 4.1 Site Class Section 1613 of the 2009 SBC provides information on earthquake loads and site ground motion needed for liquefaction potential assessment. Based on the SBC 2009 design criteria, sites are classified based on the average soil profile properties in the first 100 feet below the ground surface. The deepest boring 050113jawtl _report addendum.docx C04," Golder Associates Fred Herber May 2, 2013 High Country Homes 3 13-00007.000 for this project was advanced to a depth of 40 feet below the existing ground surface (bgs). It is our opinion that the site should be classified as a Class E site based on SBC Table 1613.5.2. 4.2 Ground Motion Parameters Ground motion parameters used for design per the SBC include the site coefficient and mapped spectral accelerations, which can be found in section 1613.5. The mapped spectral accelerations correspond to Class B conditions. Accordingly, the spectral response accelerations should be adjusted for the site- specific Class E soil conditions. The following design parameters are based on the SBC Maximum Considered Earthquake (MCE) Ground Motion, the 0.2 -second spectral acceleration (Ss), and the 1.0 -second spectral acceleration (S1) for the project site. The interpolated probabilistic ground motion values in percent gravity were obtained from the USGS java application Seismic Hazard Curves and Uniform Hazard Response Spectra, Version 5.1.0 - March 25, 2013 (http://earthquake.usgs.gov/hazards/designmaps/javacalc.php). The following results were obtained for latitude 47.478415 and longitude -122.272886 (a point located near the center of the site): Short (0.2 -second) Spectral Response (Ss): 1.462g Long (1.0 -second) Spectral Response (S1): 0.502g Note that these numbers correspond to Site Classification B and must be adjusted for Site Classification E using the International Building Code (IBC) procedures. Values adjusted for Site Class E (adjusted using the USGS java application) are as follows: Spectral Response Accelerations: Short (0.2 -second) Spectral Response (SMs): Long (1.0 -second) Spectral Response (SM1): Design Spectral Response Accelerations: Short (0.2 -second) Spectral Response (Sos): Long (1.0 -second) Spectral Response (SA: 1.316g 1.205g 0.877g 0.804g 050113jawtl _report addendum.docx Golder Associates Fred Herber May 2, 2013 High Country Homes 4 13-00007.000 5.0 CLOSING This geotechnical report addendum has been prepared exclusively for the use of High Country Homes and applies specifically to our 2002 Geotechnical Report for Macadam Road South Residential Plat included in Appendix A.

INTRODUCTION Golder Associates Inc (Golder) is pleased to present the results of our geotechnical design report for the Macadam Road South Residential Plat. The site is located between Interstate 5 and Macadam Road in Tukwila, Washington as shown on Figure 1. The scope of work for this project was presented in our proposal to you dated February 12, 2002. We proceeded with our study based on your signed authorization dated February 15, 2002. We had completed a previous report for the site titled Preliminary Geotechnical Study, Macadam Road South Residential Plat, Tukwila, Washington dated January 15, 2002. The earlier report recommended that additional explorations and engineering be completed for final design and construction. Thus the main purpose of the work presented in this report was to complete the additional work and develop recommendations suitable for permitting, design and construction of the project. The scope of this report included additional borings, additional test pits, laboratory testing, engineering analyses and development of geotechnical design and construction criteria. Our work addresses the specific site development concept depicted on the proposed Plat Plan by Jaeger Engineering dated 11/3/01 (note: we understand that the large -diameter detention pipe shown on the 11/3/01 plan has been relocated to the west away from the slope). We have conduded that the project can be developed as planned but it will be required that the buildings be pile supported due to the thickness and poor quality of the fills underlying the site. We also recommend that the structures are off set from the top of the fill slope due to the risk of shallow sloughing failures of the slopes. Alternatively, the piles could be designed to resist the lateral forces developed by these shallow slides. Golder Associates March 21, 2002 2 023-1014-100.100 2. SITE DESCRIPTION AND PROPOSED DEVELOPMENT 2.1 Proposed Development Based on the Jaeger Engineering plan, the site will be divided into seven lots fronting along Macadam Road as shown on Figure 2. We understand that three of the houses (Lots 1, 6, and 7) located on sloping ground will include a daylight basement. Some limited filling and cutting will be required to construct the houses and grade the final lots. We understand that there will be a stormwater-detention pipe some six feet in diameter and about 300 feet long. It has been relocated from its original design location near the crest of the fill slope to a new location in front of the houses. At the time we prepared this report, the exact location and design of the houses had not been determined. However, we have assumed that they will be conventional one- to two- story wood -frame structures, some with a daylight basement. In addition, we had not reviewed the revised plans showing the new detention -pipe location. 2.2 Site Description The site consists of approximately 1-3A acres, which is roughly rectangular in shape and is located between Interstate 5 (I-5) and Macadam Road in Tukwila, Washington as shown on Figure 1. Site elevation ranges from approximately 195 feet at the level portion of the property adjacent to Macadam Road to about 164 feet in the northeast corner of the property adjacent to 1-5. The site has a relatively level portion adjacent to Macadam Road. The topography then slopes down to the east towards I-5 at about 3H:1V to 4H:1V to a small swale located adjacent to 1-5. Currently the level portion of the site is mainly open with tall grasses and small brush. The sloping portion is covered with brush and small trees. We reviewed plans developed by Arnett and Associates dated 1990 showing general site layout, lot subdivisions, a proposed subsurface cut-off drain, and a proposed surface drainage system. We understand that the sub drain and surface drainage system were installed. We observed some of the surface drainage features shown on the Arnett and Associates plans during our recent investigation. These include a catch basin and a manhole located at the top of the existing fill slope in Lot 2. We understand that the site has been filled at least three times over the years. This appears to include fill placed prior to 1986, fill placed between 1986 and 1990, and some re- grading of the fill after 1990. Our aerial photographic review (Section 2.2.1) generally supports this history. Based on this information supplanted with some older topographic plans and sections, we were able to estimate the elevation of the original ground and depth of current fill. We observed evidence of a shallow scarp along the east -facing fill slope as shown on Figure 2. The scarp averages about 1.5 feet in height and extends north -south across the full length of the fill slope. Anecdotal information indicated that a slide may have occurred within the fill in the late 1980's requiring excavation of material from the drainage swale Golder Associates March 21, 2002 3 023-1014-100.100 adjacent to 1-5. In addition, it appears that the debris may have been placed back onto the fill slope. Our aerial photographic review (Section 2.3) generally supports this history. 2.3 Aerial Photograph Review As part of our study, we performed a review of aerial photographs from 1936 to 2000. The aerial photographs were available at Walker and Associates located in Tukwila, Washington. A list of the aerial photos we reviewed, along with a summary of our observations, is presented in the table below. Date of Photo Approximate Scale Comments/Observations 1936 1 inch = 1000 feet Black -and -white photos. Pre -highway 1-5 and SR -599. Pre -fill. Macadam Road present. Cultivated orchards up slope of road. Tall trees observed on old slope below road. No evidence of disturbed ground. April 10,1956 1 inch = 1000 feet Black -and -white photos. Same observations as 1936 except no orchards observed up slope of Macadam Road. Slope above road looks to be recently cleared. May 4,1980 1 inch = 1000 feet Black -and -white photos.

July 10,1990 1 inch = 1000 feet Color photos. Fill has been recently placed on portions of the site. Very limited vegetative cover observed on the fill (older fill surface only). Possible scarps observed in the vicinity of Lots 3, 4, and 5 near crest in east -facing fill slope (Figure 3) These possible scarps are located in the area of the scarps observed on the site during this investigation. October 7, 2000 1 inch = 2000 feet Color photos. Site is well vegetated with light brown grasses on flat portion of site and dark green (young trees) on fill slopes. No evidence of disturbed ground. Ground surface obscured by vegetative cover. Golder Associates March 21, 2002 4 023-1014-100.100 3. FIELD EXPLORATION 3.1 Subsurface Explorations The subsurface explorations included eight test pits and three borings. The locations are shown on Figure 2 and the logs are included in Appendix A. Golder excavated 6 test pits (TP -1 to TP -6) in 1999 located in the flat portion of the property adjacent to Macadam Road. These test pits were excavated to depths of between 10 and 15 feet below the existing ground surface (bgs). The most recent geotechnical subsurface exploration program was performed between February 25 and February 27, 2002. The work consisted of two additional test pits (TP -7 and TP -8) excavated adjacent to 1-5 at the toe of the existing fill slope. In addition, we completed three borings located near the crest of the existing fill slope in Lots 1, 4, and 7. The location of the test pits and borings are shown on the Site Plan (Figure 2). Samples were obtained from the borings using a SPT split -spoon sampler. Bag samples were taken from the test pits. The borings were performed by Boretec Drilling out of Spokane, Washington using a custom-built MM 45 drill rig to depths of between 36.5 and 40 feet bgs. The test pits were excavated to depths of about 13 feet with a Komatsu PC 120 excavator. At test pit TP -8, the excavator became stuck in soft, saturated soils. This required another excavator to aid in extracting the excavator. The test pits and borings were located in the field based on hand measurements and pacing from existing site features and should be considered approximate. The field explorations were performed under the full-time observation of a representative of our firm who recorded soils information including depths, stratigraphy, soil engineering characteristics and groundwater occurrence. The observed conditions were recorded on Golder Field Test Pit Log forms and Record of Borehole forms (See Appendix A). Disturbed but representative samples were collected and returned to our laboratory for further examination and testing. The exploration test pits were backfilled immediately after the subsurface conditions were recorded. Some settlement of the backfill in the test pits should be expected. 3.2 Laboratory Testing Laboratory testing consisted of washed sieves and minus #200 washed sieves. The results are included in Appendix B. Golder Associates March 21, 2002 5 023-1014-100.100 4. SUBSURFACE CONDITIONS 4.1 Soil Waldron (1962)' mapped the geology in the area of the site as undifferentiated pre- Vashon drift overlain by Vashon-aged ground moraine deposits (till). These deposits are generally hard and/or very dense as they have been deposited in front of or beneath the advancing glacier and have been overridden by the full weight of the glacier. Recessional outwash and lacustrine silt, clay, and peat are mapped by Waldron on the east side of the site in the area of I-5. These units are generally loose to compact and/or soft to very stiff as they were deposited during the recession of the Vashon glacier and were generally not overridden by the full weight of the glacier. Based on the soil conditions observed in our test pits and borings, the site is mantled by compact to very loose fill underlain by recessional lacustrine deposits. These units are then underlain by dense to very dense till and stiff glaciolacustrine deposits. Soil units encountered during our geotechnical exploration program are summarized in more detail below: • Fill — Fill was encountered in all the test pits and borings. The depth of the fill ranges from about 12 feet bgs adjacent to Macadam Road, to about 27 feet bgs at the crest of the fill slope in Lot 4. The fill encountered was variable but can be split into two units. • Upper Fill: The upper 5 to 15 feet beneath the flat portion of the site consisted primarily of compact to dense fine to coarse sand with varying amounts of silt and gravel and minor organics. Some of the 1999 test pits encountered building debris in the fill including bricks, chunks of asphalt, pieces of concrete, pipe, etc. This upper compact to dense fill layer may represent the newer fill placed after 1983 as discussed in Section 2.3. • Lower Fill: Underlying the upper fill, the explorations encountered very soft and very loose finer -grained fill. This unit was also observed in the two test pits excavated at the toe of the fill slope adjacent to I-5 and in the borings. The lower very loose and very soft fill unit consists of primarily silt ranging to silty day with a trace to little sand and gravel and a little to some fine-grained organics. The lower fill unit can vary to fine to coarse sand with some clayey silt and a trace of organics. The more organic -rich fill was observed in the areas of Lot 1 and the toe of the fill slope adjacent to I-5. • Recessional Lacustrine Deposit — This unit was observed in boring GB -1 located in Lot 4 between about 26.5 feet and 28.5 feet bgs, and in the test pits located at the base of the fill slope in Lots 2 and 4. The unit consists of interbedded loose to compact, silt, fine to medium sand, and firm to very stiff, dayey silt. The unit contains a trace of gravel throughout and is commonly iron oxide stained. Pocket penetrometer readings in this unit range from about 1.5 to 3.5 tsf (tons per square foot). ' Waldron, Howard H., 1962. Geology of the Des Moines Quadrangle, Washington: U. S. Geological Survey Map GQ -159. Golder Associates March 21, 2002 6 023-1014-100.100 • Till - We encountered this unit underlying the fill in all the borings at depths of between 22 and 28.5 feet bgs. The unit consisted of generally compact to dense, nonstratified, silty, fine to coarse sand with a little fine to coarse rounded gravel. The till can vary to clayey silt and is iron oxide stained. • Glaciolacustrine Deposit — This unit was encountered underlying the till in boring GB -3. This unit consists of very stiff, massive to faintly laminated, clay ranging to silty day with thin interbeds of fine to medium sand. The unit contains ice -loading features such as jointing and contorted bedding. 4.2 Surface Water and Groundwater Surface water was observed in the drainage swale at the base of the fill slope bordering the eastern property line. No surface water was observed on the fill slope or in the swale adjacent to Macadam Road. No evidence of seepage was observed on the existing fill slope. Groundwater seepage was observed in all but one of our test pits and likely represents the groundwater levels at that time. We measured the groundwater level in GB -1 at the time of drilling. In the other holes, groundwater did not stabilize in the hole during drilling. In these boreholes we estimated the depth to groundwater by the depth where we first encountered soils that appeared saturated. The approximate depth and elevation of groundwater occurrence in our test pits and borings is summarized below. Test Pit/Borehole Number Date of Groundwater Observation Approximate Ground Surface Elevation (feet MSL) Approximate Depth to Groundwater (feet bgs) Approximate Groundwater Elevation (feet MSL) TP -2 4/8/99 198 9.5 188.5 TP -3 4/8/99 197 13 184 TP -4 4/8/99 1% 13 183 TP -5 418/99 195 8 187 TP -6 4/8/99 194 7 187 TP -7 2/28/02 166 2 164 TP -8 2/28/02 174 4.5 169.5 GB -1 2/25/02 195 12.5 182.5 GB -2 2/25/02 195 10 185 GB -3 2/26/02 193 10 183 Note: The groundwater depths and elevations shown above are approximate and are for the time and date shown. The depth to groundwater in the borings is interpreted based on observed wet soil conditions in the samples. Based on this information, the groundwater levels were about 10 feet below the ground surface on the western level portion of the site becoming shallower near the toe of the fill slope. Groundwater levels should be expected to fluctuate depending on the time of year. The groundwater levels at this site would generally be the highest during late winter and spring depending on precipitation. Golder Associates March 21, 2002 7 023-1014-100.100 5. ENGINEERING EVALUATIONS 5.1 Liquefaction And Lateral Spreading Assessment Loose granular soils below the water table can be susceptible to liquefaction and lateral spreading during a major seismic event. Accordingly, we completed an evaluation of these risks for the proposed site development. These risks can be assessed based on the SPT blow counts and the composition of the soils. Typically, fine-grained soils and/or soils with SPT values in excess of about 10 have a low liquefaction risk Based on the exploration, loose/soft soils below the water table occurred the lower fill unit as described in Section 41. This unit is primarily fine-grained consisting of silt ranging to silty clay with a trace to little sand and gravel and a little to some fine-grained organics. In some areas it varies to fine to coarse sand with some dayey silt and a trace of organics. In general organic and plastic soils are considered to have a low susceptibility to liquefaction. The more granular soils still had relatively high percentage of silt. We completed a liquefaction evaluation of these soils using the general Seed procedures, which takes into account the high silt content. The results indicated that these materials generally have a low liquefaction potential except for a few lorali7ed areas of deaner loose sands within the lower fills. We considered the risk of lateral spreading or slope failure caused by liquefaction. Conservatively assuming a continuous zone of liquefiable soils in the slope area, the calculations indicate a low risk of seismically induced slope failure. This was based on the likely range in the liquefied undrained sand strengths and the limited fill heights. Thus the only credible failure mode would be some localized sloughing. In summary, the credible risks associated with liquefaction include localized shallow sloughing of slopes. Although some post -liquefaction settlement is theoretically possible, due to the localized nature of liquefiable zones and the depth to these zones, it is unlikely that any settlement effects would actually occur. 5.2 Stability We completed several stability evaluations using the computer code XSTABL. The results indicated a factor of safety of a deep-seated failure was adequate, generally in excess of 1.5 for even very conservative strength assumptions in the lower fill. These included +'=24 degrees, c'=0 for drained conditions and (0=0, c'=500 psf for the undrained conditions. However, the calculated factor of safety was relatively low for shallow sloughing failures along the slopes where the lower loose/soft soils are exposed. This is not surprising and is consistent with the observed scarp that likely occurred about the time that the fill was placed. Calculated seismic stability is adequate related to a deep-seated failure but some localed sloughing could occur. We discussed the possible effects of liquefaction on the slope stability in Section 5.1 above. Golder Associates March 21, 2002 8 023-1014-100.100 For a range of possible strength parameters, the static and seismic factor of safety against shallow sloughing type of failures is considered marginal for areas where the lower loose/soft fill is exposed and the fill slope is steeper than about 3.5H:1V (16 degrees). 5.3 Foundation and Development of Stable Slopes We considered supporting the houses on spread footings bearing in the upper compact to dense fills. However, we were concerned about the poor quality of the underlying fills and the risk of settlement induced by loads, creep in the organic portions of the fill and/or seismic vibrations. Thus, we recommend that the structures be supported on piles founded in the dense, stiff native soils underlying the fill. Specific design criteria are presented in Section 6 below. Although the fill slopes are considered stable with respect to a deep-seated failure, as discussed in Section 5.2 above, areas of steep slopes with exposed loose/soft soils are susceptible to shallow sloughing failures. In general, this risk is considered low as evidenced by the current slopes exhibiting no evidence of recent movement with the current scarp having likely occurred shortly after the fill was placed. However, we recommend that the slopes be modified to reduce these risks in areas that are in dose proximity to the proposed houses such as Lots 6 and 7. Section 6 below presents specific recommendations. Golder Associates March 21, 2002 9 023-1014-100.100 6. DESIGN RECOMMENDATIONS 6.1 Foundation Recommendations We recommended that the houses be supported on pile foundations. There are many pile foundation options available. Based on our experience, we recommended that auger -cast piles be used. Small -diameter driven piles may have difficulty driving through the upper dense fills and conventional -sized driven piles are likely more expensive than auger -cast piles. Below, we present design criteria for auger -cast piles. ff other pile types are found top be more economical, we can develop alternative design criteria. Auger cast piles should be augered through the fill and recessional soils into the underlying dense/stiff glacially overridden soils. Figure 4 shows the estimated elevations to the top of this bearing layer. In general, the depth from the existing ground surface to this bearing layer varies from about 10 to 15 feet along the front of the proposed house locations to about 20 to 25 feet on the backside of the house locations. We present the following auger -cast -pile design criteria: • MINIMUM DIAMETER: We recommend that the piles have a minimum diameter of 14 -inches • MINIMUM DEPTH: All piles should be advanced at least 4 feet into the bearing material. For budgeting purposes Figure 4 can be used to estimate pile lengths. The actual installed pile lengths may vary depending on conditions encountered in the field. • PILE CAPACITIES: The following table presents the allowable axial compression load based on pile diameter and depth of penetration into bearing. Since the loads are likely small, the design will probably be based on 14 -inch -diameter piles with the minimum 4 -foot penetration into dense/stiff bearing. Penetration Into Bearing ft• Allowable Axial Capacity - kips Diameter — in 14 16 18 4 49 61 73 5 53 65 78 6 57 69 82 7 60 73 87 8 64 77 92 9 68 82 97 10 71 86 101 * Estimated elevation to top of bearing based on figure 4 For short-term transient loads, the above values can be increased by 1/3. If a load factor design is used, the ultimate axial loads can be assumed to be twice the allowable loads. Settlement is expected to be less than '/z -inch. Golder Associates March 21, 2002 10 023-1014-100.100 • MINIMUM REBAR: Regardless of the structural requirements, we recommended that as a minimum of one small rebar is placed full depth into the grout after auger removal as a check on hole "necking". If the rebar cannot be installed full depth, the pile should be rejected. 6.2 Slab On Grade The first -floor slab and garage slab can be designed as a normal slab -on -grade provided that the existing subgrade is prepared as discussed in Section 5.6. All slabs should be underlain by a capillary break, which consists of at least six inches of sand drainage blanket overlain by plastic sheeting. The drainage blanket should meet the requirements of section 9-03.13(1) of the 1991 Washington State Standard Specifications for Road, Bridge and Municipal Construction. At the contractor's option, the plastic can be overlain by about two inches of drainage sand. It has been our experience that some contractors feel that the upper sand layer is necessary for proper curing of the concrete. 6.3 Foundation Drainage Normal footing and wall drains should be provided for any building that has interior slabs below the elevation of the adjacent finished ground surface. Below -grade basement walls should be provided with drainage provisions consisting of either a drainage fabric or a dean well graded sand and gravel backfill. Foundation drains should consist of a four -inch -diameter, perforated, rigid, plastic pipe embedded in dean, free -draining sand and gravel, meeting the requirements of Section 9.03.13 and Section 9.03.12(4), respectively, of the 1998 Washington State Standard Specifications for Road, Bridge, and Municipal Construction. A positive means of draining the sand below adjacent floor slabs should also be provided. This could be done with either a separate slab drainage system or cutouts in the footings. Roof drains should be connected to a separate system and not drain into the under drain or wall drain system. 6.4 Slope Setbacks and Regrading As discussed in Sections 5.2 and 5.3, areas of steep slopes with exposed loose/soft soils are susceptible to shallow sloughing failures. In general, this risk is considered low as evidenced by the current slopes exhibiting no evidence of recent movement. However, we recommend the following to minimize the risk of any slope impacts on the utilities or houses: Golder Associates March 21, 2002 11 023-1014-100.100 • HOUSE SET BACKS: The pile caps for all house structures should be located at least 10 horizontal feet from the top of a projected imaginary 3H:1V line from the toe of the slope (18 degrees). This criterion can be met by locating the house away from the top of the slope, by lowering the grades on the backside of the house to create the setback (likely requires a daylight basement), and/or flattening the slopes. In general, this will impact Lots 1, 5, 6 and 7. • UTILITIES: In general, utilities should meet the same setback criteria as presented above. If any utilities must cross the slope, they should be aligned down the fall line of the slope and placed at a depth of at least 5 feet (3 feet at the toe area of the slope), which should be below any active sloughing zones. • DRAINAGE: It is essential to limit any surface runoff down the slope or ponding of water above the slopes. Thus all surface drainage should be controlled and tight lined before draining down the slope or drained towards the front of the site. Golder Associates March 21, 2002 12 023-1014-100.100 7. CONSTRUCTION CONSIDERATIONS 7.1 Subgrade Preparation Since the structure will be pile supported, the existing fills need not be removed. However, the subgrade needs to be stabilized in order to provide adequate support for construction equipment, the slab -on -grade and pavement areas. In general, the near -surface fills are well -graded sand and gravel with minimal silt. Except during very wet weather, this material should provide an adequate subgrade. However, in areas where the upper fill is thin, on the slopes, and/or in areas where the grade is lowered the lower fill may be encountered. This lower fill is generally a wet, fine-grained material that will provide an inadequate subgrade for equipment and construction activities particularly during wet weather. The contractor should anticipate that over -excavation and replacement or a stabilizing layer of fill or ballast may be required in these areas. Use of heavy woven geotextiles in these areas may be warranted. If the soft lower fills are exposed in the excavation for a lower slab the subgrade will need to be stabilize. This should consist of some over -excavated, placement of a heavy woven geotextile, and backfilled with compacted structural fill. The depth of the over - excavation depends on the nature of the unsuitable areas with the intent to provide an adequate subgrade for the slab. In general, the maximum depth of over -excavation will likely be on the order of 18 -inches. 7.2 Fill In general mass earthworks will be minimal. Fills placed in areas of pavements and inside the building footprint should be well graded sand and gravel placed in maximum 12 -inch -thick loose lifts and compacted to at least 95 percent of maximum dry density as determined by ASTM 1557, Method D. The upper granular on-site excavated fill can generally be used for structural fill provided they can be properly moisture conditioned and contain no organic debris, building debris, or other unsuitable materials. 7.3 Auger Cast Piles Auger cast piles are particularly sensitive to the installation methods and contractor experience. Poor equipment and/or inexperienced contractors can result in piles that are improperly installed and, in the worst case, piles that are completely "necked" providing essentially no significant resistance. Thus, it is essential that auger cast piles be installed by qualified, experienced contractors with the full time construction monitoring of experienced geotechnical field engineers. General monitoring requirements include the auger down pressure, identification of cuttings, grout pressure, the rate of auger withdrawal, and grout take. It is also Golder Associates March 21, 2002 13 023-1014-100.100 recommended that as a minimum one small rebar is placed full depth into the grout after auger removal as a check on hole "necking". If the rebar cannot be installed full depth, the pile should be rejected. 7.4 Construction Monitoring Critical geotechnical aspects of construction should be monitored by a qualified geotechnical field engineer. This includes pavement and slab subgrade preparation, placement and compaction of structural fills, construction of wall and footing drains, and installation of the auger cast piles.

USE OF REPORT This report has been prepared exclusively for the use of John Nalewajek and his consultants for specific application to this project. The condusions and recommendations presented in this report are based on the explorations accomplished for this study and conversations regarding the proposed development of the site. Once the site project plans are finalized, we recommend that we be given the opportunity to review the plans and specifications to verify that they are in accordance with our recommendations. The integrity and performance of the auger cast pile foundation system and the development of a suitable pavement/slab subgrade depends greatly on proper construction procedures. Therefore, it is recommended that a geotechnical engineer be retained to provide geotechnical services during the critical aspects of the project. The Golder field borings were performed in general accordance with locally accepted geotechnical engineering practice to provide information for the areas explored. There are possible variations in the subsurface conditions between the borings and variations with in the groundwater conditions with time. We recommend that a contingency for unanticipated conditions be included in the construction schedule and budget.

Two wetlands (Wetlands A and B) were identified and delineated in the northeastern and southeastern portions of the site during the field investigations and subsequently surveyed (Figure 1). On March 28, 2013 we conducted a site meeting to review the wetland delineation and classification with Sandra Whiting, City of Tukwila Urban Environmentalist. The wetland delineation and standard buffers as depicted on Figure 1 were preliminarily approved by Sandra during this meeting. Also during this site visit the ordinary high water of the stream located to the east of the property was mapped and is depicted on Figure 1. Attachment A contains data sheets prepared for representative locations in both the upland and wetland. These data sheets document the vegetation, soils, and hydrology information that aided in the wetland boundary delineation. Wetland A Wetland A is located in the northeastern corner of the site and consists of a Slope Hydrogeomorphic Class containing a Palustrine Emergent plant community dominated by reed canarygrass (Phalaris arundinacea). At the time of the field investigations soils within the wetland were generally saturated to the surface. Fred Herber May 14, 2013 Page 2 Runoff within the wetland appears to infiltrate and is separated from the off-site stream by a small berm. Wetland A meets the criteria for a Category IV wetland (Attachment B) and requires a standard 50 -foot buffer plus 10 -foot building setback per TMC 18.45.080.D. Wetland B and Off -Site Stream Wetland B is located in the southeastern corner of the site and also consists of a Slope Hydrogeomorphic Class. Vegetation within Wetland B consisted of a small Palustrine Forested plant community that contained a canopy of red alder (Alnus rubra) with an understory of red elderberry (Sambucus racemosa), Indian plum (Oemleria cerasiformis), and rose (Rosa sp.). Groundcover was dominated by reed canarygrass. Soils within the wetland were generally saturated to the surface and runoff drains east directly into the off-site stream. This stream flows from south to north along the east side of a chain link fence located under the Sound Transit rail line. It is my understanding that native plantings along the riparian corridor of the stream were installed as mitigation associated with construction of the rail line. Wetland B meets the criteria for a Category IV wetland (Attachment B) and requires a standard 50 -foot buffer plus 10 -foot building setback per TMC 18.45.080.D. The off-site stream has been classified by the City as a Type 3 (Np) watercourse and requires a standard 80 -foot buffer plus 10 -foot structure setback from the ordinary high water of the stream per TMC 18.45.100.C. Proposed Proiect The proposed Macadam Short Plat has been designed to avoid all permanent impacts to the sensitive areas and their buffers. The only work that must occur within the buffer is the installation of an above -ground stormwater conveyance pipe and associated dispersion pad along the slope in the northeastern portion of the site. This pipe would be installed within a heavily disturbed portion of the buffer and would be designed to avoid any significant native vegetation. All temporary buffer impacts associated with the installation would be restored following construction.

PRELIMINARY APPROVAL CONDITIONS (to be addressed prior to final short plat approval) Sensitive areas mitigation approved in permit L14-0001 for work within wetland and stream buffers shall be completed as part of the Public Works construction permit. As part of the Public Works Permit, provide a plan for how maintenance and monitoring of the mitigation area will occur and how access for maintenance and monitoring will be maintained if ownership of individual lots changes during the five-year maintenance and monitoring period. A bond shall be submitted by the property owner as part of the Public Works Permit for 150% of the maintenance and monitoring cost for the five-year period. The following note was added to Sheet 1 of the short plat "The City and JK Monarch, LLC are hereby granted an easement with the right to access any property on this short plat for a period of 5 years or until the wetland performance bond is released. The purpose of this easement is for the monitoring and maintenance of wetland mitigation plantings." A performance bond will be provided before short plat recording. w w w. a t u r e g r e e n c o n s u i t a n t s. c o m 2) The neighbor to the north of the project site, Thelma Davis, submitted comments on this short plat as part of the Notice of Application period. Some of her concerns related to whether any existing trees would need tobe removed as part of construction work, whether any existing trees could become unstable as a result of the site work, and whether one of her trees will need to be trimmed. As part of the Public Works Permit, please submit a plan indicating which trees are proposed to be removed and which are proposed to be retained. Note that a permit is required for removal of trees located within sensitive areas, including wetland, watercourses, steep slopes, and sensitive area buffers. See sheet S10 of the engineering drawings for tree removal and protections. 3) Make the following changes to the Macadam Short Plat survey sheets: a. All easements should be shown with the information on Sheet 3 of 5. Please transfer the information shown on Sheet 5 of 5 to Sheet 3 of 5, excluding the tree information on the left side of the plan sheet. The tree information is important for review and should be submitted with materials submitted part of the Public Works construction permit. However, the tree information does not need to be included on the survey that is recorded for the short plat. Adding the Public and Private Storm Easements to page 3 at the current drawing scale would make the drawings very hard to read due to the size and locations of the easements. We believe that to change the scale of the drawing would create a disconnect of the Short Plat as a whole, making it more difficult for future surveyors and engineers to recreate the boundary and easements. Having the boundary on page 3 gives a clear and readable map of the entire Short Plat, with clear and readable dimensions. An additional note added to page 3 directs the user to page5 for Public and Private Storm Easements. Once on page 5, they can view the entirety of the system with ties to the boundary making it easier for future users to recreate the easements and their relation to the boundary. All tree information has been removed. Can sensitive areas information shown on the right side of Sheet 4 of 5 be added to Sheet 3 of 5? The topography information on the left side of Sheet 4 of 5 should be included in plans submitted for the Public Works construction permit, but it does not need to be included on the survey that will be recorded for the short plat. If adding the sensitive areas information to Sheet 3 of 5 is not possible or makes Sheet 3 of 5 difficult to read, please revise Sheet 4 of 5 to add the new lot lines proposed with the short plat. For the same reasons stated above, we believe it is best for the Sensitive Areas to stand alone, for clear, readable dimensions, with ties to the Enw w w. a z u r e g r e e n t o n s u 1 t a n t s. c o m boundary. In taking this approach we believe the Public Welfare is better protected by creating maps that are easier to read and reproduce the boundary, easements, and sensitive areas, while showing the subdivision as a whole Setback note on Sheet 3 of 5: Revise to say "The rear setback will be 10' from the wetland and/or stream buffer, except for Lot 7, on which the rear setback from the wetland and /or stream buffer may be 5', as approved under Special Permission Permit L14-0001." Revise the 10' setback distance line shown on Sheet 4 of 5 (or Sheet 3 if transferred) to reflect this. Setback Note has been revised. d. Environmentally Sensitive Area Notice: Add the following note on Sheet 2 of 5: (Note was added to sheet 1) Environmentally Sensitive Area Notice This property contains environmentally sensitive areas and/or environmentally sensitive area buffers, as defined by the City of Tukwila Environmentally Sensitive Areas Ordinance No. 2301, codified in Title 18 of the Tukwila Municipal Code. The provisions of the Tukwila Environmentally Sensitive Areas Ordinance apply to this property. Limitations may exist on actions and developments in or near the environmentally sensitive area or buffers present on this property. For further information regarding limitations, please contact the City of Tukwila Department of Community Development or its successor agency. This Notice shall run with the land and shall not be removed except upon specific written authorization by the City of Tukwila or its successor agency.

The City SEPA Responsible Official has previously determined that this application does not require a SEPA threshold determination because it is categorically exempt. This letter serves as the Notice of Decision per TMC 18.104.170. Based on the latest project submittal, preliminary approval is granted subject to the conditions stated below. The conditions imposed are to ensure the short plat is consistent with the Criteria for Preliminary Approval listed at TMC 17.12.020 C in the Tukwila Subdivision Code. PRELIMINARY APPROVAL CONDITIONS (to be addressed prior to final short plat approval) 1) Sensitive areas mitigation approved in permit L14-0001 for work within wetland and stream buffers shall be completed as part of the Public Works construction permit. As part of the Public Works Permit, provide a plan for how maintenance and monitoring of the mitigation area will occur and how access for maintenance and monitoring will be maintained if ownership of individual lots changes during the five-year maintenance and monitoring period. A bond shall be submitted by the property owner as part of the Public Works Permit for 150% of the maintenance and monitoring cost for the five-year period. 2) The neighbor to the north of the project site, Thelma Davis, submitted comments on this short plat as part of the Notice of Application period. Some of her concerns related to whether any existing trees would need to be removed as part of construction work, whether any existing trees could become unstable as a result of the site work, and whether one of her trees will need to be trimmed. As part of the Public Works Permit, please submit a plan indicating which trees are proposed to be removed and which are proposed to be retained. Note that a permit is required for removal of trees located within sensitive areas, including wetland, watercourses, steep slopes, and sensitive area buffers. 3) Make the following changes to the Macadam Short Plat survey sheets: a. All easements should be shown with the information on Sheet 3 of 5.

(Golder) is pleased to provide this addendum report to High Country Homes for a proposed residential housing plat located due south of South 138th St along Macadam Road in Tukwila, Washington (subject property). Golder completed a geotechnical report for the subject property titled Geotechnical Design Report: Macadam Road South Residential Plat, Tukwila, Washington dated March 21, 2002. The report was for a proposed residential development that consisted of seven single family homes. We understand that High Country Homes has secured the rights to the report and the property and is proposing slight modifications to the plat design and requested an update of our 2002 report. The scope of this addendum was completed in accordance with our Proposal No. P1300007 dated March 21, 2013 and was based on discussions with Mr. Fred Herber on March 19, 2013. 1.0 BACKGROUND AND PURPOSE In March of 2002 Golder completed a geotechnical site investigation and provided foundation design recommendations for construction of a seven lot single family residential development at the subject property. A copy of Golder's 2002 report is included in Appendix A. The property consists of an approximate 1.58 -acre lot (Job 2013) located between Interstate 5 (1-5) and Macadam Road in Tukwila. Site elevation ranges from approximately 128 feet above mean sea level (MSL) at the portion of the property adjacent to Macadam Road to about 96 feet above MSL in the northeast corner of the property adjacent to 1-5 (Job 2013). The approximate western half of the property is graded level adjacent to Macadam Road before sloping downward towards 1-5 and includes a small area covered with gravel. The 2002 geotechnical investigation included eight test pits (TP -1 through TP -8) and three borings (GB -1 through GB -3). Results of the subsurface investigation identified up to 27 feet of fill materials onsite. Recommendations were provided in our report for supporting the house foundations on augercast piles that extended through the fill and into the native soil below. During our 2002 investigation we identified evidence of a shallow scarp from a slump along the eastern facing fill slope on the property. The slump was described as occurring approximately in the late 1980's and then was covered or filled back in with fill. The purpose of this addendum report is to provide an update of the seismic code recommendations, and discuss any changes that we observed on the site that would result in any changes to the recommendations contained in our 2002 report. The current site development plans are preliminary but appear to closely math the 2002 development plans. The number of lots will remain the same but we have not been furnished with a grading or foundation plan for this report. 050113jawtl report addendum.docx Golder Associates Inc. 18300 NE Union Hill Road, Suite 200 Redmond, WA 98052 USA Tel: (425) 883-0777 Fax: (425) 882-5498 www.golder.com Golder Associates: Operations in Africa, Asia, Australasia, Europe, North America and South America Golder, Golder Associates and the GA globe design are trademarks of Golder Associates Corporation Fred Herber May 2, 2013 High Country Homes 2 13-00007.000 2.0 DATA REVIEW Golder reviewed the Washington State Geologic Information Portal and the Department of Ecology Well Log Database for any geologic information on the site since 2002. No new information was found on the databases. During our site visit we observed a vertical 5 -inch diameter PVC casing with a cap at the northwest corner of the property. The purpose of the casing is unknown. We searched the well log database for any record of a monitoring well being installed on the subject property but no wells were recorded. 3.0 SITE RECONNAISSANCE A site reconnaissance of the subject property was performed by a Golder geotechnical engineer on March 25, 2013 to observe any changes in site conditions since our 2002 report. We observed the area of the scarp described in the 2002 report, the remaining slopes and the upland portion of the site. Currently the property contains a small gravel parking area to the south adjacent to Macadam Road. To the north of the gravel parking area, the lot is lightly vegetated with grass. Some of the upland area is rutted out due to off-road vehicles. Drainage within this rutted area is poor and as a result the ground surface is soft. The northern and eastern crest and subsequent slopes are vegetated with blackberry and young Alder trees. The northern boundary of the site slopes downward toward the northeast from Macadam Road. The northern boundary is separated by a chain link fence from the adjacent property. The ground surface between the chain link fence and the toe of the fill slope was saturated with some areas of standing water. Sand bags were stacked along the base of the chain link fence likely to prevent water from draining into the adjacent property. An area of standing water was observed along the northeastern corner of the property. The eastern boundary of the property borders the elevated track of the King County Link Light Rail (light rail) from Seattle -Tacoma International Airport. The light rail maintains an easement adjacent to the property which extends along the toe of the fill embankment. The easement is landscaped with small shrubs and trees on a moderate eastern sloping face. The easement is sloped to drain surface water into a ditch that is oriented parallel with the centerline of the light rail. The ditch is lined with cobbles and is outside of the property boundary. A chain link fence exists adjacent to the light rail and the subject property. The slopes are heavily vegetated with grass, blackberry and young trees. The crest of the fill slope embankment did not display any obvious signs of displacement as noted previously in our 2002 report. The slope was heavily vegetated and there were no signs of recent slumps or slope movement. Due to the thickness of the vegetation it is possible that surface erosion or small scale slumps may be obscured. However, if they occur they would be small and unlikely to have a significant impact on the overall slope stability. In our opinion, the slope conditions appear relatively unchanged since our 2002 investigation. 4.0 SEISMIC DESIGN This section provides updated seismic design parameters that supersede those in our 2002 report. The 2009 Seattle Building Code (SBC) is available online and was referenced on March 26, 2013 for seismic site class designation determination (http://ecodes.biz/ecodes support/free resources/Seattle2009/ 09seattle building/09seattle building main.htm). The seismic design section provides information to be used as a basis for seismic design of structures. 4.1 Site Class Section 1613 of the 2009 SBC provides information on earthquake Toads and site ground motion needed for liquefaction potential assessment. Based on the SBC 2009 design criteria, sites are classified based on the average soil profile properties in the first 100 feet below the ground surface. The deepest boring 050113jawtl_report addendum.docx Golder Associates Fred Herber May 2, 2013 High Country Homes 3 13-00007.000 for this project was advanced to a depth of 40 feet below the existing ground surface (bgs). It is our opinion that the site should be classified as a Class E site based on SBC Table 1613.5.2. 4.2 Ground Motion Parameters Ground motion parameters used for design per the SBC include the site coefficient and mapped spectral accelerations, which can be found in section 1613.5. The mapped spectral accelerations correspond to Class B conditions. Accordingly, the spectral response accelerations should be adjusted for the site- specific Class E soil conditions. The following design parameters are based on the SBC Maximum Considered Earthquake (MCE) Ground Motion, the 0.2 -second spectral acceleration (Ss), and the 1.0 -second spectral acceleration (S1) for the project site. The interpolated probabilistic ground motion values in percent gravity were obtained from the USGS java application Seismic Hazard Curves and Uniform Hazard Response Spectra, Version 5.1.0 - March 25, 2013 (http://earthquake.usgs.gov/hazards/desianmaps/javacalc.php). The following results were obtained for latitude 47.478415 and longitude -122.272886 (a point located near the center of the site): Short (0.2 -second) Spectral Response (Ss): 1.462g Long (1.0 -second) Spectral Response (Si): 0.502g Note that these numbers correspond to Site Classification B and must be adjusted for Site Classification E using the International Building Code (IBC) procedures. Values adjusted for Site Class E (adjusted using the USGS java application) are as follows: Spectral Response Accelerations: Short (0.2 -second) Spectral Response (SMs): Long (1.0 -second) Spectral Response (SM1): Design Spectral Response Accelerations: Short (0.2 -second) Spectral Response (Sos): Long (1.0 -second) Spectral Response (Sol): 1.316g 1.205g 0.877g 0.804g 050113jawtl_reportaddendum.docx • \:-Golder Associates Fred Herber May 2, 2013 High Country Homes 4 13-00007.000 5.0 CLOSING This geotechnical report addendum has been prepared exclusively for the use of High Country Homes and applies specifically to our 2002 Geotechnical Report for Macadam Road South Residential Plat included in Appendix A.

INTRODUCTION Golder Associates Inc. (Golder) is pleased to present the results of our geotechnical design report for the Macadam Road South Residential Plat. The site is located between Interstate 5 and Macadam Road in Tukwila, Washington as shown on Figure 1. The scope of work for this project was presented in our proposal to you dated February 12, 2002. We proceeded with our study based on your signed authorization dated February 15, 2002. We had completed a previous report for the site titled Preliminary Geotechnical Study, Macadam Road South Residential Plat, Tukwila, Washington dated January 15, 2002. The earlier report recommended that additional explorations and engineering be completed for final design and construction. Thus the main purpose of the work presented in this report was to complete the additional work and develop recommendations suitable for permitting, design and construction of the project. The scope of this report included additional borings, additional test pits, laboratory testing, engineering analyses and development of geotechnical design and construction criteria. Our work addresses the specific site development concept depicted on the proposed Plat Plan by Jaeger Engineering dated 11/3/01 (note: we understand that the large -diameter detention pipe shown on the 11/3/01 plan has been relocated to the west away from the slope). We have concluded that the project can be developed as planned but it will be required that the buildings be pile supported due to the thickness and poor quality of the fills underlying the site. We also recommend that the structures are off set from the top of the fill slope due to the risk of shallow sloughing failures of the slopes. Alternatively, the piles could be designed to resist the lateral forces developed by these shallow slides. Golder Associates March 21, 2002 2 023-1014-100.100 2. SITE DESCRIPTION AND PROPOSED DEVELOPMENT 2.1 Proposed Development Based on the Jaeger Engineering plan, the site will be divided into seven lots fronting along Macadam Road as shown on Figure 2. We understand that three of the houses (Lots 1, 6, and 7) located on sloping ground will include a daylight basement. Some limited filling and cutting will be required to construct the houses and grade the final lots. We understand that there will be a stormwater-detention pipe some six feet in diameter and about 300 feet long. It has been relocated from its original design location near the crest of the fill slope to a new location in front of the houses. At the time we prepared this report, the exact location and design of the houses had not been determined. However, we have assumed that they will be conventional one- to two- story wood -frame structures, some with a daylight basement. In addition, we had not reviewed the revised plans showing the new detention -pipe location. 2.2 Site Description The site consists of approximately 1-% acres, which is roughly rectangular in shape and is located between Interstate 5 (I-5) and Macadam Road in Tukwila, Washington as shown on Figure 1. Site elevation ranges from approximately 195 feet at the level portion of the property adjacent to Macadam Road to about 164 feet in the northeast corner of the property adjacent to I-5. The site has a relatively level portion adjacent to Macadam Road. The topography then slopes down to the east towards I-5 at about 3H:1V to 4H:1V to a small swale located adjacent to I-5. Currently the level portion of the site is mainly open with tall grasses and small brush. The sloping portion is covered with brush and small trees. We reviewed plans developed by Arnett and Associates dated 1990 showing general site layout, lot subdivisions, a proposed subsurface cut-off drain, and a proposed surface drainage system. We understand that the sub drain and surface drainage system were installed. We observed some of the surface drainage features shown on the Arnett and Associates plans during our recent investigation. These include a catch basin and a manhole located at the top of the existing fill slope in Lot 2. We understand that the site has been filled at least three times over the years. This appears to include fill placed prior to 1986, fill placed between 1986 and 1990, and some re- grading of the fill after 1990. Our aerial photographic review (Section 2.2.1) generally supports this history. Based on this information supplanted with some older topographic plans and sections, we were able to estimate the elevation of the original ground and depth of current fill. We observed evidence of a shallow scarp along the east -facing fill slope as shown on Figure 2. The scarp averages about 1.5 feet in height and extends north -south across the full length of the fill slope. Anecdotal information indicated that a slide may have occurred within the fill in the late 1980's requiring excavation of material from the drainage swale Golder Associates 1 March 21, 2002 ) 3 ) 023-1014-100.100 adjacent to I-5. In addition, it appears that the debris may have been placed back onto the fill slope. Our aerial photographic review (Section 2.3) generally supports this history. 2.3 Aerial Photograph Review As part of our study, we performed a review of aerial photographs from 1936 to 2000. The aerial photographs were available at Walker and Associates located in Tukwila, Washington. A list of the aerial photos we reviewed, along with a summary of our observations, is presented in the table below. Date of Photo 1 Approximate Scale Comments/Observations 1936 1 inch = 1000 feet Black -and -white photos. Pre -highway I-5 and SR -599. Pre -fill. Macadam Road present. Cultivated orchards up slope of road. Tall trees observed on old slope below road. No evidence of disturbed ground. April 10, 1956 1 inch = 1000 feet Black -and -white photos. Same observations as 1936 except no orchards observed up slope of Macadam Road. Slope above road looks to be recently cleared. May 4,1980 1 inch = 1000 feet Black -and -white photos. Highways I-5 and SR -599 exist. Pre -fill. Turnout adjacent to Macadam Road in northwest corner of property. Tall trees on slope below road look straight. Remainder of site to east is low-lying with low vegetative growth (grasses?). Drainage swale and fence line present adjacent to I- 5. No evidence of disturbed ground in or around site. July 10,1990 1 inch = 1000 feet Color photos. Fill has been recently placed on portions of the site. Very limited vegetative cover observed on the fill (older fill surface only). Possible scarps observed in the vicinity of Lots 3, 4, and 5 near crest in east -facing fill slope (Figure 3) These possible scarps are located in the area of the scarps observed on the site during this investigation. October 7, 2000 1 inch = 2000 feet Color photos. Site is well vegetated with light brown grasses on flat portion of site and dark green (young trees) on fill slopes. No evidence of disturbed ground. Ground surface obscured by vegetative cover. Golder Associates March 21, 2002 4 023-1014-100.100 3. FIELD EXPLORATION 3.1 Subsurface Explorations The subsurface explorations included eight test pits and three borings. The locations are shown on Figure 2 and the logs are included in Appendix A. Golder excavated 6 test pits (TP -1 to TP -6) in 1999 located in the flat portion of the property adjacent to Macadam Road. These test pits were excavated to depths of between 10 and 15 feet below the existing ground surface (bgs). The most recent geotechnical subsurface exploration program was performed between February 25 and February 27, 2002. The work consisted of two additional test pits (TP -7 and TP -8) excavated adjacent to I-5 at the toe of the existing fill slope. In addition, we completed three borings located near the crest of the existing fill slope in Lots 1, 4, and 7. The location of the test pits and borings are shown on the Site Plan (Figure 2). Samples were obtained from the borings using a SPT split -spoon sampler. Bag samples were taken from the test pits. The borings were performed by Boretec Drilling out of Spokane, Washington using a custom-built MM 45 drill rig to depths of between 36.5 and 40 feet bgs. The test pits were excavated to depths of about 13 feet with a Komatsu PC 120 excavator. At test pit TP -8, the excavator became stuck in soft, saturated soils. This required another excavator to aid in extracting the excavator. The test pits and borings were located in the field based on hand measurements and pacing from existing site features and should be considered approximate. The field explorations were performed under the full-time observation of a representative of our firm who recorded soils information induding depths, stratigraphy, soil engineering characteristics and groundwater occurrence. The observed conditions were recorded on Golder Field Test Pit Log forms and Record of Borehole forms (See Appendix A). Disturbed but representative samples were collected and returned to our laboratory for further examination and testing. The exploration test pits were backfilled immediately after the subsurface conditions were recorded. Some settlement of the backfill in the test pits should be expected. 3.2 Laboratory Testing Laboratory testing consisted of washed sieves and minus #200 washed sieves. The results are included in Appendix B. Golder Associates March 21, 2002 5 023-1014-100.100 4. SUBSURFACE CONDITIONS 4.1 Soil Waldron (1962)' mapped the geology in the area of the site as undifferentiated pre- Vashon drift overlain by Vashon-aged ground moraine deposits (till). These deposits are generally hard and/or very dense as they have been deposited in front of or beneath the advancing glacier and have been overridden by the full weight of the glacier. Recessional outwash and lacustrine silt, day, and peat are mapped by Waldron on the east side of the site in the area of I-5. These units are generally loose to compact and/or soft to very stiff as they were deposited during the recession of the Vashon glacier and were generally not overridden by the full weight of the glacier. Based on the soil conditions observed in our test pits and borings, the site is mantled by compact to very loose fill underlain by recessional lacustrine deposits. These units are then underlain by dense to very dense till and stiff glaciolacustrine deposits. Soil units encountered during our geotechnical exploration program are summarized in more detail below: • Fill — Fill was encountered in all the test pits and borings. The depth of the fill ranges from about 12 feet bgs adjacent to Macadam Road, to about 27 feet bgs at the crest of the fill slope in Lot 4. The fill encountered was variable but can be split into two units. • Upper Fill: The upper 5 to 15 feet beneath the flat portion of the site consisted primarily of compact to dense fine to coarse sand with varying amounts of silt and gravel and minor organics. Some of the 1999 test pits encountered building debris in the fill including bricks, chunks of asphalt, pieces of concrete, pipe, etc. This upper compact to dense fill layer may represent the newer fill placed after 1983 as discussed in Section 2.3. • Lower Fill: Underlying the upper fill, the explorations encountered very soft and very loose finer -grained fill. This unit was also observed in the two test pits excavated at the toe of the fill slope adjacent to I-5 and in the borings. The lower very loose and very soft fill unit consists of primarily silt ranging to silty clay with a trace to little sand and gravel and a little to some fine-grained organics. The lower fill unit can vary to fine to coarse sand with some clayey silt and a trace of organics. The more organic -rich fill was observed in the areas of Lot 1 and the toe of the fill slope adjacent to I-5. • Recessional Lacustrine Deposit — This unit was observed in boring GB -1 located in Lot 4 between about 26.5 feet and 28.5 feet bgs, and in the test pits located at the base of the fill slope in Lots 2 and 4. The unit consists of interbedded loose to compact, silt, fine to medium sand, and firm to very stiff, dayey silt. The unit contains a trace of gravel throughout and is commonly iron oxide stained. Pocket penetrometer readings in this unit range from about 1.5 to 3.5 tsf (tons per square foot). ' Waldron, Howard H., 1962. Geology of the Des Moines Quadrangle, Washington: U. S. Geological Survey Map GQ -159. Golder Associates March 21, 2002 6 023-1014-100.100 • Till - We encountered this unit underlying the fill in all the borings at depths of between 22 and 28.5 feet bgs. The unit consisted of generally compact to dense, nonstratified, silty, fine to coarse sand with a little fine to coarse rounded gravel. The till can vary to clayey silt and is iron oxide stained. • Glaciolacustrine Deposit — This unit was encountered underlying the till in boring GB -3. This unit consists of very stiff, massive to faintly laminated, clay ranging to silty clay with thin interbeds of fine to medium sand. The unit contains ice -loading features such as jointing and contorted bedding. 4.2 Surface Water and Groundwater Surface water was observed in the drainage swale at the base of the fill slope bordering the eastern property line. No surface water was observed on the fill slope or in the swale adjacent to Macadam Road. No evidence of seepage was observed on the existing fill slope. Groundwater seepage was observed in all but one of our test pits and likely represents the groundwater levels at that time. We measured the groundwater level in GB -1 at the time of drilling. In the other holes, groundwater did not stabilize in the hole during drilling. In these boreholes we estimated the depth to groundwater by the depth where we first encountered soils that appeared saturated. The approximate depth and elevation of groundwater occurrence in our test pits and borings is summarized below.

The depth to groundwater in the borings is interpreted based on observed wet soil conditions in the samples. Based on this information, the groundwater levels were about 10 feet below the ground surface on the western level portion of the site becoming shallower near the toe of the fill slope. Groundwater levels should be expected to fluctuate depending on the time of year. The groundwater levels at this site would generally be the highest during late winter and spring depending on precipitation. Golder Associates March 21, 2002 7 023-1014-100.100 5. ENGINEERING EVALUATIONS 5.1 Liquefaction And Lateral Spreading Assessment Loose granular soils below the water table can be susceptible to liquefaction and lateral spreading during a major seismic event. Accordingly, we completed an evaluation of these risks for the proposed site development. These risks can be assessed based on the SPT blow counts and the composition of the soils. Typically, fine-grained soils and/or soils with SPT values in excess of about 10 have a low liquefaction risk. Based on the exploration, loose/soft soils below the water table occurred the lower fill unit as described in Section 41. This unit is primarily fine-grained consisting of silt ranging to silty day with a trace to little sand and gravel and a little to some fine-grained organics. In some areas it varies to fine to coarse sand with some clayey silt and a trace of organics. In general organic and plastic soils are considered to have a low susceptibility to liquefaction. The more granular soils still had relatively high percentage of silt. We completed a liquefaction evaluation of these soils using the general Seed procedures, which takes into account the high silt content. The results indicated that these materials generally have a low liquefaction potential except for a few lorali7ed areas of leaner loose sands within the lower fills. We considered the risk of lateral spreading or slope failure caused by liquefaction. Conservatively assuming a continuous zone of liquefiable soils in the slope area, the calculations indicate a low risk of seismically induced slope failure. This was based on the likely range in the liquefied undrained sand strengths and the limited fill heights. Thus the only credible failure mode would be some localized sloughing. In summary, the credible risks associated with liquefaction include localized shallow sloughing of slopes. Although some post -liquefaction settlement is theoretically possible, due to the localized nature of liquefiable zones and the depth to these zones, it is unlikely that any settlement effects would actually occur. 5.2 Stability We completed several stability evaluations using the computer code XSTABL. The results indicated a factor of safety of a deep-seated failure was adequate, generally in excess of 1.5 for even very conservative strength assumptions in the lower fill. These included +'=24 degrees, c'=0 for drained conditions and =0, c'=500 psf for the undrained conditions. However, the calculated factor of safety was relatively low for shallow sloughing failures along the slopes where the lower loose/soft soils are exposed. This is not surprising and is consistent with the observed scarp that likely occurred about the time that the fill was placed. Calculated seismic stability is adequate related to a deep-seated failure but some localed sloughing could occur. We discussed the possible effects of liquefaction on the slope stability in Section 5.1 above. Golder Associates March 21, 2002 8 023-1014-100.100 For a range of possible strength parameters, the static and seismic factor of safety against shallow sloughing type of failures is considered marginal for areas where the lower loose/soft fill is exposed and the fill slope is steeper than about 3.5H:1V (16 degrees). 5.3 Foundation and Development of Stable Slopes We considered supporting the houses on spread footings bearing in the upper compact to dense fills. However, we were concerned about the poor quality of the underlying fills and the risk of settlement induced by loads, creep in the organic portions of the fill and/or seismic vibrations. Thus, we recommend that the structures be supported on piles founded in the dense, stiff native soils underlying the fill. Specific design criteria are presented in Section 6 below. Although the fill slopes are considered stable with respect to a deep-seated failure, as discussed in Section 5.2 above, areas of steep slopes with exposed loose/soft soils are susceptible to shallow sloughing failures. In general, this risk is considered low as evidenced by the current slopes exhibiting no evidence of recent movement with the current scarp having likely occurred shortly after the fill was placed. However, we recommend that the slopes be modified to reduce these risks in areas that are in close proximity to the proposed houses such as Lots 6 and 7. Section 6 below presents specific recommendations. Golder Associates l March 21, 2002 6. DESIGN RECOMMENDATIONS 6.1 Foundation Recommendations 9 0234014-100.100 We recommended that the houses be supported on pile foundations. There are many pile foundation options available. Based on our experience, we recommended that auger -cast piles be used. Small -diameter driven piles may have difficulty driving through the upper dense fills and conventional -sized driven piles are likely more expensive than auger -cast piles. Below, we present design criteria for auger -cast piles. If other pile types are found top be more economical, we can develop alternative design criteria. Auger cast piles should be augered through the fill and recessional soils into the underlying dense/stiff glacially overridden soils. Figure 4 shows the estimated elevations to the top of this bearing layer. In general, the depth from the existing ground surface to this bearing layer varies from about 10 to 15 feet along the front of the proposed house locations to about 20 to 25 feet on the backside of the house locations. We present the following auger -cast -pile design criteria: • MINIMUM DIAMETER: We recommend that the piles have a minimum diameter of 14 -inches • MINIMUM DEPTH: All piles should be advanced at least 4 feet into the bearing material. For budgeting purposes Figure 4 can be used to estimate pile lengths. The actual installed pile lengths may vary depending on conditions encountered in the field. • PILE CAPACITIES: The following table presents the allowable axial compression load based on pile diameter and depth of penetration into bearing. Since the loads are likely small, the design will probably be based on 14 -inch -diameter piles with the minimum 4 -foot penetration into dense/stiff bearing. Penetration Into Bearing ft* Allowable Axial Capacity - kips Diameter — in 14 16 18 4 49 61 73 5 53 65 78 6 57 69 82 7 60 73 87 8 64 77 92 9 68 82 97 10 71 86 101 * Estimated elevation to top of bearing based on figure 4 For short-term transient loads, the above values can be increased by 1/3. If a load factor design is used, the ultimate axial loads can be assumed to be twice the allowable loads. Settlement is expected to be less than 1/z -inch. Golder Associates March 21, 2002 10 023-1014-100.100 • MINIMUM REBAR: Regardless of the structural requirements, we recommended that as a minimum of one small rebar is placed full depth into the grout after auger removal as a check on hole "necking". If the rebar cannot be installed full depth, the pile should be rejected. 6.2 Slab On Grade The first -floor slab and garage slab can be designed as a normal slab -on -grade provided that the existing subgrade is prepared as discussed in Section 5.6. All slabs should be underlain by a capillary break, which consists of at least six inches of sand drainage blanket overlain by plastic sheeting. The drainage blanket should meet the requirements of section 9-03.13(1) of the 1991 Washington State Standard Specifications for Road, Bridge and Municipal Construction. At the contractor's option, the plastic can be overlain by about two inches of drainage sand. It has been our experience that some contractors feel that the upper sand layer is necessary for proper curing of the concrete. 6.3 Foundation Drainage Normal footing and wall drains should be provided for any building that has interior slabs below the elevation of the adjacent finished ground surface. Below -grade basement walls should be provided with drainage provisions consisting of either a drainage fabric or a dean well graded sand and gravel backfill. Foundation drains should consist of a four -inch -diameter, perforated, rigid, plastic pipe embedded in clean, free -draining sand and gravel, meeting the requirements of Section 9.03.13 and Section 9.03.12(4), respectively, of the 1998 Washington State Standard Specifications for Road, Bridge, and Municipal Construction. A positive means of draining the sand below adjacent floor slabs should also be provided. This could be done with either a separate slab drainage system or cutouts in the footings. Roof drains should be connected to a separate system and not drain into the under drain or wall drain system. 6.4 Slope Setbacks and Regrading As discussed in Sections 5.2 and 5.3, areas of steep slopes with exposed loose/soft soils are susceptible to shallow sloughing failures. In general, this risk is considered low as evidenced by the current slopes exhibiting no evidence of recent movement. However, we recommend the following to minimize the risk of any slope impacts on the utilities or houses: Golder Associates March 21, 2002 11 023-1014-100.100 • HOUSE SET BACKS: The pile caps for all house structures should be located at least 10 horizontal feet from the top of a projected imaginary 3H:1V line from the toe of the slope (18 degrees). This criterion can be met by locating the house away from the top of the slope, by lowering the grades on the backside of the house to create the setback (likely requires a daylight basement), and/or flattening the slopes. In general, this will impact Lots 1, 5, 6 and 7. • UTILITIES: In general, utilities should meet the same setback criteria as presented above. If any utilities must cross the slope, they should be aligned down the fall line of the slope and placed at a depth of at least 5 feet (3 feet at the toe area of the slope), which should be below any active sloughing zones. • DRAINAGE: It is essential to limit any surface runoff down the slope or ponding of water above the slopes. Thus all surface drainage should be controlled and tight lined before draining down the slope or drained towards the front of the site. Golder Associates March 21, 2002 12 023-1014-100.100 7. CONSTRUCTION CONSIDERATIONS 7.1 Subgrade Preparation Since the structure will be pile supported, the existing fills need not be removed. However, the subgrade needs to be stabilized in order to provide adequate support for construction equipment, the slab -on -grade and pavement areas. In general, the near -surface fills are well -graded sand and gravel with minimal silt. Except during very wet weather, this material should provide an adequate subgrade. However, in areas where the upper fill is thin, on the slopes, and/or in areas where the grade is lowered the lower fill may be encountered. This lower fill is generally a wet, fine-grained material that will provide an inadequate subgrade for equipment and construction activities particularly during wet weather. The contractor should anticipate that over -excavation and replacement or a stabilizing layer of fill or ballast may be required in these areas. Use of heavy woven geotextiles in these areas may be warranted. If the soft lower fills are exposed in the excavation for a lower slab the subgrade will need to be stabilize. This should consist of some over -excavated, placement of a heavy woven geotextile, and backfilled with compacted structural fill. The depth of the over - excavation depends on the nature of the unsuitable areas with the intent to provide an adequate subgrade for the slab. In general, the maximum depth of over -excavation will likely be on the order of 18 -inches. 7.2 Fill In general mass earthworks will be minimal. Fills placed in areas of pavements and inside the building footprint should be well graded sand and gravel placed in maximum 12 -inch -thick loose lifts and compacted to at least 95 percent of maximum dry density as determined by ASTM 1557, Method D. The upper granular on-site excavated fill can generally be used for structural fill provided they can be properly moisture conditioned and contain no organic debris, building debris, or other unsuitable materials. 7.3 Auger Cast Piles Auger cast piles are particularly sensitive to the installation methods and contractor experience. Poor equipment and/or inexperienced contractors can result in piles that are improperly installed and, in the worst case, piles that are completely "necked" providing essentially no significant resistance. Thus, it is essential that auger cast piles be installed by qualified, experienced contractors with the full time construction monitoring of experienced geotechnical field engineers. General monitoring requirements include the auger down pressure, identification of cuttings, grout pressure, the rate of auger withdrawal, and grout take. It is also Golder Associates March 21, 2002 13 023-1014-100.100 recommended that as a minimum one small rebar is placed full depth into the grout after auger removal as a check on hole "necking". If the rebar cannot be installed full depth, the pile should be rejected. 7.4 Construction Monitoring Critical geotechnical aspects of construction should be monitored by a qualified geotechnical field engineer. This includes pavement and slab subgrade preparation, placement and compaction of structural fills, construction of wall and footing drains, and installation of the auger cast piles.

USE OF REPORT This report has been prepared exclusively for the use of John Nalewajek and his consultants for specific application to this project. The conclusions and recommendations presented in this report are based on the explorations accomplished for this study and conversations regarding the proposed development of the site. Once the site project plans are finalized, we recommend that we be given the opportunity to review the plans and specifications to verify that they are in accordance with our recommendations. The integrity and performance of the auger cast pile foundation system and the development of a suitable pavement/slab subgrade depends greatly on proper construction procedures. Therefore, it is recommended that a geotechnical engineer be retained to provide geotechnical services during the critical aspects of the project. The Golder field borings were performed in general accordance with locally accepted geotechnical engineering practice to provide information for the areas explored. There are possible variations in the subsurface conditions between the borings and variations with in the groundwater conditions with time. We recommend that a contingency for unanticipated conditions be included in the construction schedule and budget.
