Most of the proposed sewer lines will be installed under public streets, but a few segments cross undeveloped land with wetlands and their buffers. These segments that cross sensitive areas are located near 42nd Ave S just south of SR 518 and east of the service area just north of Crystal Springs Park; both sensitive areas are connection points to existing sewer lines. All impacts to sensitive areas will be temporary impacts related to the construction and installation of the sewer mains. After installation of the sewer lines, the trenches will be covered and the areas that were disturbed with construction equipment can be restored. Routine maintenance of the sewer lines is not anticipated to cause ongoing or repeated sensitive area disturbance; manholes will provide adequate points of access should maintenance be needed in the future. Over ninety percent of the proposed sewer loop line segments will be installed via open trench and in a few areas, directional drilling will be used to install the lines. Directional drilling minimizes disturbance to the ground and sensitive areas by drilling the path for the pipes underneath the ground. Open trench technique consists of digging a deep trench with heavy construction equipment, placing the pipes, then covering with the dirt displaced to create the trench. For open trench construction, the areas disturbed will be limited to 10 feet on either side of the pipe location for a maximum width of 20 feet. Manhole installation will disturb a 20 ft2 x 20 ft2 area at each manhole site. All sensitive areas that will be disturbed for the construction of the sewer loop project will be restored to pre -construction grades and replanted with native species. Tukwila Municipal Code Chapter 18.54- Tree Regulations applies to this project. Construction of the sewer loop will require the removal of 48 trees in sensitive areas. As this application was received on January 26, 2018- the old tree regulations apply and the project is not subject to the newly passed ordinance for tree removal, Ordinance 2570. Trees removed from wetlands and wetland buffers in the sewer loop project area are subject to the replacement ratios below. Diameter of Existing Tree Removed No. of Replacement Trees Required 4 - 8 inches 1 8 -12 inches 2 12-18inches 4 18 - 24 inches 6 >24 inches 8 The removal of 48 trees in sensitive areas will require 149 replacement trees. A recommended condition of approval is that after the areas needed for construction of the sewer infrastructure are cleared, areas suitable for replacement trees will be identified by City Planning and Valley View representatives together. It is crucial that replacement trees in Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 3 sensitive areas be planted in areas not anticipated to be disrupted again for routine sewer maintenance and will not interfere or disrupt the new sewer infrastructure. After the areas needed for construction are cleared and the site visit identifying good locations for replacement trees has occurred, the District will submit revised mitigation/planting plans for City approval. Of the 149 replacement trees required, whatever is not able to be planted in onsite sensitive areas will require payment into the City's in -lieu tree fund. At the time of this writing, the in -lieu fee is $124 per replacement tree. BACKGROUND The soil in the project area is poor for infiltration and many septic systems have failed over the years, resulting in fecal bacteria levels unsafe for direct contact found downstream from the homes. Valley View Sewer has submitted and received funding from the Clean Water State Revolving Fund administered by the Washington State Department of Ecology to fund the majority of costs related to sewer installation. Because the project will result in cleaner stormwater and the planting plans for disturbed areas will replace nonnative species with native shrubs and trees, the project is expected to maintain or improve the habitat and filtering functions of the small areas of wetlands and wetland buffers that will be disturbed with construction. DECISION CRITERIA This report provides an overview of project consistency with applicable criteria for allowed uses in sensitive areas, followed by discussion of the mitigation plan, comments, conclusions, and recommendations. Criteria Staff Analysis 18.45.070 Sensitive Area Permitted Uses B. PERMITTED USES SUBJECT TO ADMINISTRATIVE REVIEW. Sewer infrastructure is classified as a utility by the Tukwila Municipal Code, and installation of new facilities is a The following uses may be permitted only after administrative review permitted use subject to Director and approval by the Director: approval. 1. Maintenance and repair of existing uses and facilities where alteration or additional fill materials will be placed or heavy The proposed sewer infrastructure construction equipment used. New surface water discharges to sensitive areas or their routing has considered the presence of buffers from detention facilities, pre -settlement ponds or streams, wetlands and their buffers and other surface water management structures may be the routing has been changed from the allowed provided that the discharge meets the clean water original design to minimize the standards of RCW 90.48 and WAC 173.200 and 173.201 disturbance of these sensitive areas. as amended, and does not adversely affect water level Despite several Type 4 streams located fluctuations in the wetland or adversely affect watercourse within the project boundary, the sewer Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 4 habitat and watercourse flow conditions relative to the existing rate. Water quality monitoring may be required as a condition of use 3. Bioswales and dispersion outfalls are the only storm water facilities allowed in wetland or watercourse buffers. Water quality monitoring may be required as a condition of use 4. Enhancement or other mitigation including landscaping with native plants. 5. Essential Utilities. a. Essential utilities must be constructed to minimize, or where possible avoid, disturbance of the sensitive area and its buffer. b. All construction must be designed to protect the sensitive area and its buffer against erosion, uncontrolled storm water, restriction of groundwater movement, slides, pollution, habitat disturbance, any loss of flood carrying capacity and storage capacity, and excavation or fill detrimental to the environment. c. Upon completion of installation of essential utilities, sensitive areas and their buffers must be restored to pre- project configuration, replanted as required and provided with maintenance care until newly planted vegetation is established. In addition, mitigation to offset impacts to sensitive areas or their buffers must be carried out in accordance with the standards and mitigation ratios of this chapter. d. All crossings must be designed for shared facilities in order to minimize adverse impacts and reduce the number of crossings. Dredging, Digging or Filling. a. Dredging, digging or filling within a sensitive area or its buffer may occur only with the permission of the Director and only for the following purposes: (1) Uses permitted by TMC Sections 18.45.080, 18.45.090, 18.45.110, 18.45.130; (2) Maintenance of an existing watercourse; (3) Enhancement or restoration of habitat in conformance with an approved mitigation plan identified in a sensitive area study; (4) Natural system interpretation, education or research when undertaken by, or in cooperation with, the City; (5) Flood control or water quality enhancement by the City; (6) Maintenance of existing water quality controls, for normal maintenance needs and for any diversion, rerouting, piping or other alteration permitted by TMC Chapter 18.45; (7) Filling of abandoned mines. b. Any dredging, digging or filling shall be performed in a manner that will minimize sedimentation in the water. Every effort will be made to perform such work at the time of year when the impact lines will temporarily disturb only small sections of Category 4 wetlands and wetland buffers, with minimal crossings. The District will utilize directional drilling to install sewer lines under the Type 4 watercourse identified east of the service area, north of Crystal Springs Park. By using directional drilling, impacts to the area are minimized and the only disturbance will be the movements of the drilling equipment. It is not economically feasible to use directional drilling for all of the sewer lines, so the most sensitive areas have been identified for the technology. Traditional open -trench construction will be used in most of the other areas within the project area, and impacts limited to a 20-foot wide swath where the heavy equipment will travel and construction take place. Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 5 can be lessened. c. Upon completion of construction, the area affected must be restored to an appropriate grade, replanted according to a plan approved by the Director, and provided with care until newly planted vegetation is established. 18.45.080 Wetlands Designations, Ratings, and Buffers A. WETLAND DESIGNATIONS. 1. For the purposes of TMC Chapter 18.45, "wetlands" are defined in the Definitions chapter of this title. A wetland boundary is the line delineating the outer edge of a wetland established by using the approved federal wetland delineation manual and applicable regional supplements. 2. Wetland determinations and delineation of wetland boundaries shall be made by a qualified professional, as described in TMC Section 18.45.040. 3. Wetland areas within the City of Tukwila have certain characteristics and functions and have been influenced by urbanization and related disturbances. Wetland functions include, but are not limited to, the following: a. Improving water quality; b. Maintaining hydrologic functions (reducing peak flows, decreasing erosion, groundwater recharge, flood storage); and c. Providing habitat for plants, mammals, fish, birds, and amphibians. B. WETLAND RATINGS Wetlands shall be designated in accordance with the Washington State Wetlands Rating System for Western Washington, (Washington State Department of Ecology, August 2004, Publication #04-06-025) as Category I, II, III, or IV as listed below: 1. Category I wetlands are those that: i) represent a unique or rare wetland type; or ii) are more sensitive to disturbance than most wetlands; or iii) are relatively undisturbed and contain ecological attributes that are impossible to replace within a human lifetime; or iv) provide a high level of functions. The following types of wetlands listed by Washington Department of Ecology and potentially found in Tukwila are Category I: a. Estuarine wetlands (deepwater tidal habitats with a range of fresh -brackish -marine water chemistry and daily tidal cycles, salt and brackish marshes, intertidal mudflats, bays, sounds, and coastal rivers); b. Wetlands that perform many functions well and score at least 70 points in the Western Washington Wetlands Rating System. 2. Category II wetlands are difficult, though not impossible, to replace and provide high levels of some functions. These wetlands occur more commonly than Category I wetlands, but still need a relatively high level of protection. The following types of wetlands listed by Washington Department of Ecology and potentially found in Tukwila The proposed loop sewer project will cross or travel through several wetlands and buffers identified as Wetlands NB, C, X, Z and 2 (Attachment B). These Wetlands are all Category 3 or 4 wetlands, with 80 ft. and 50 ft. wide buffers, respectively. Rating forms for the wetlands and streams can be found in Attachment B, Revised Critical Area Report. The rating forms and categories of wetlands described are consistent with the City's Sensitive Areas Inventory. The functions and categories of the wetlands present will not decrease with project approval, nor will the buffer widths be altered. It is possible that the functions of the wetlands could increase over time, as the project will improve water quality and enhance the landscape with native plants. Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 6 are Category II wetlands: a. The wetland is documented as regionally significant waterfowl or shorebird areas by the State Department of Fish and Wildlife. b. Wetlands that perform functions well. Wetlands scoring between 51-69 points (out of 100) on the questions related to the functions present. 3. Category III wetlands have a moderate level of functions (scores between 30 and 50 points). Wetlands scoring between 30-50 points generally have been disturbed in some ways and are often Tess diverse or more isolated from other natural resources in the landscape than Category II wetlands. 4. Category IV wetlands have the lowest levels of functions (scores less than 30 points) and are often heavily disturbed. While these are wetlands that should be able to be replaced or improved, they still need protection because they may provide some important functions. Any disturbance of these wetlands will be considered on a case by case basis. WETLAND BUFFERS — A buffer area shall be established adjacent to designated wetland areas. The purpose of the buffer area shall be to protect the integrity and functions of the wetland area. Any land alteration must be located out of the buffer areas as required by this section. Wetland buffers are intended in general to: 1. Minimize long-term impacts of development on properties containing wetlands; 2. Protect wetlands from adverse impacts during development; 3. Preserve the edge of the wetland and its buffer for its critical habitat value; 4. Provide an area to stabilize banks, to absorb overflow during high water events and to allow for slight variation of aquatic system boundaries over time due to hydrologic or climatic effects; 5. Reduce erosion and increased surface water runoff; 6. Reduce loss of or damage to property; 7. Intercept fine sediments from surface water runoff and serve to minimize water quality impacts; and 8. Protect the sensitive area from human and domestic animal disturbances. An undisturbed sensitive area or buffer may substitute for the yard setback and landscape requirements of the TMC Chapter 18.50 and 18.52. WETLAND BUFFER WIDTHS — The following standard buffers shall be established from the wetland edge: Category I and II Wetland: 100-foot buffer. Category III Wetland: 80-foot buffer. Category IV Wetland: 50-foot buffer. 18.45.090 Wetlands Uses, Alterations and Mitigation A. No use or development may occur in a Category I, Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 7 Category II, Category III or Category IV wetland or its buffer except as specifically allowed by TMC Chapter 18.45. Any use or development allowed is subject to review and approval by the Director. Where required, a mitigation plan must be developed and must comply with the standards of mitigation required in TMC Chapter 18.45. In addition, federal and/or state authorization is required for direct impacts to waters of the United States or the State of Washington. The proposed use of new sewer infrastructure (essential utilities) is a permitted use in wetlands and their buffers subject to Director approval. B. ALTERATIONS 1. Alterations to wetlands are discouraged and are limited to the minimum necessary for project feasibility. Requests for alterations must be accompanied by a mitigation plan, are subject to Director approval, and may be approved only if the following findings are made: a. The alteration will not adversely affect water quality; b. The alteration will not adversely affect fish, wildlife, or their habitat; c. The alteration will not have an adverse effect on drainage and/or storm water detention capabilities; C. MITIGATION SEQUENCING — Applicants shall demonstrate that reasonable efforts have been examined with the intent to avoid and minimize impacts to wetlands and wetland buffers. When an alteration to a wetland or its required buffer is proposed, such alteration shall be avoided, minimized or compensated for in the following order of preference: 1. Avoiding the impact altogether by not taking a certain action or parts of an action; 2. Minimizing wetland and wetland buffer impacts by limiting the degree or magnitude of the action and its implementation, by using appropriate technology, or by taking affirmative steps to avoid or reduce impacts; 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 the life of the action; 5. Compensating for the impact by replacing, enhancing, or providing substitute resources or environments; and/or 6. Monitoring the impact and taking appropriate corrective measures. All impacts proposed are temporary in nature. Wetlands or their buffers will not be permanently altered with project approval. The temporary alterations to wetlands resulting from construction of the sewer lines will not adversely affect water quality, fish, wildlife or their habitat, or have an adverse effect on drainage and stormwater detention capabilities. The applicant has demonstrated consideration to sensitive areas by routing the sewer loop lines around streams and their buffers and minimizing routing in or near wetlands and their buffers. Additionally, the use of directional drilling in the most sensitive areas (Wetland 2) will minimize disturbances to natural areas and limit impacts of construction. Proposed mitigation will take place after construction of the sewer infrastructure. All ground disturbances will be restored to prior elevations and native plants including trees will be planted in the disturbed areas. D. WETLAND MITIGATION PLAN CONTENT. 1. The mitigation plan shall be developed as part of a sensitive area study by a specialist approved by the Director. Wetland and/or buffer alteration or relocation may be allowed only when a mitigation plan clearly demonstrates that the changes would be an improvement of Valley View Sewer has prepared and submitted plans for the restoration and replanting of sensitive areas disturbed Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 8 wetland and buffer quantitative and qualitative functions. The plan shall follow the performance standards of TMC Chapter 18.45 and show how water quality, wildlife and fish habitat, and general wetland quality would be improved. 2. The scope and content of a mitigation plan shall be decided on a case -by -case basis taking into account the degree of impact and the extent of the mitigation measures needed. As the impacts to the sensitive area increase, the mitigation measures to offset these impacts will increase in number and complexity. 3. For wetlands, the format of the mitigation plan should follow that established in Wetland Mitigation in Washington State, Part 2 — Developing Mitigation Plans (Washington Department of Ecology, Corps of Engineers, EPA, March 2006 or as amended). 4. The components of a complete mitigation plan are as follows: a. Baseline information of quantitative data collection or a review and synthesis of existing data for both the project impact zone and the proposed mitigation site. b. Environmental goals and objectives that describe the purposes of the mitigation measures. This should include a description of site selection criteria, identification of target evaluation species and resource functions. c. Performance standards of the specific criteria for fulfilling environmental goals and for beginning remedial action or contingency measures. They may include water quality standards, species richness and diversity targets, habitat diversity indices, or other ecological, geological or hydrological criteria. d. A detailed construction plan of the written specifications and descriptions of mitigation techniques. This plan should include the proposed construction sequence and construction management and be accompanied by detailed site diagrams and blueprints that are an integral requirement of any development proposal. e. A monitoring and/or evaluation program that outlines the approach for assessing a completed project for the specified monitoring period. An outline shall be included that spells out how the monitoring data will be evaluated by agencies that are tracking the mitigation project's progress. f. Contingency plan identifying potential courses of action and any corrective measures to be taken when monitoring or evaluation indicates project performance standards have not been met. g. Performance security or other assurance devices as described in TMC Section 18.45.210. by construction activities (Attachment D). These plans show a 20' wide maximum area where construction impacts will occur. The planting plans show native plants suitable for wetland areas including vine maple, redosier dogwood, honeysuckle, Indian plum, and snowberry plants. On a site visit with Valley View District staff on April 26th, the City's Urban Environmentalist discussed the absence of tree species from the replanting plans. The plantings plans submitted show many shrub species, but no trees. Because it is difficult to discern what areas might be most suitable for tree plantings (out of the way of areas that will not be disturbed later with sewer maintenance activities, areas where deeper roots will not interfere with future system maintenance, etc.) with the land forested and undisturbed, we agreed to visit the site again once it has been cleared for the sewer pipe installation and identify the locations where trees will be planted after construction is finished and the land restored to pre -development grades. These tree species and their locations will then be submitted by the District via revised planting/mitigation plans for City review and approval. E. MITIGATION STANDARDS. 1. Types of Wetland Mitigation: a. Mitigation for wetlands shall follow the mitigation sequencing steps in this chapter and may include the following types of actions: (1) Restoration: All impacts to the sensitive areas (wetlands and wetland buffers) will be temporary impacts related to construction of the sewer lines. As Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 9 a) Re-establishment. The manipulation of the physical, chemical or biological characteristics of a site with the goal of restoring wetland functions to a former wetland, resulting in a net increase in wetland acres and functions; b) Rehabilitation. The manipulation of the physical, chemical or biological characteristics of a site with the goal of repairing historic functions and processes of a degraded wetland, resulting in a gain in wetland functions but not acreage; (2) Creation (establishment). The manipulation of the physical, chemical or biological characteristics to develop a wetland on an upland or deepwater site, where a biological wetland did not previously exist; (3) Enhancement. The manipulation of the physical, chemical or biological characteristics to heighten, intensify, or improve specific functions (such as vegetation) or to change the growth stage or composition of the vegetation present, resulting in a change in wetland functions but not in a gain in wetland acreage. (4) A combination of the three types. b. Required mitigation ratios are described in TMC Section 18.45.090.E.b.(1). Alternate mitigation ratios may be accepted by the Director upon presentation of justification based on best available science that shows the proposed compensation represents a roughly proportional exchange for the proposed impacts. (1)Alterations are not permitted to Category I or II wetlands unless specifically exempted under the provisions of this program. When alterations are allowed, mitigation ratios for Category I wetlands shall be at a 4:1 for creation or re- establishment, 8:1 for rehabilitation, and 16:1 for enhancement. Mitigation ratios for Category II wetlands shall be at 3:1 for creation or re-establishment, 6:1 for rehabilitation and 12:1 for enhancement. Creation or re-establishment shall be contiguous to the wetland, unless an exception is authorized by the Director. For Category II estuarine wetlands, re-establishment, creation and enhancement ratios will be decided on a case -by -case basis. (2) Alterations to Category III wetlands are prohibited except where unavoidable and mitigation sequencing in accordance with this chapter has been utilized and where mitigation is carried out in accordance with the standards in the section. Mitigation for any alteration to a Category III wetland must be provided at a ratio of 2:1 for creation or re- establishment, 4:1 for rehabilitation and 8:1 for enhancement alone. (3) Mitigation for alteration to a Category IV wetland will be 1.5:1 for creation or re-establishment, 3:1 for rehabilitation or 6:1 for enhancement. Where only a portion of a Category IV wetland is filled, the potential functionality of the remaining reduced wetland must be considered in mitigation planning. 2. The following shall be considered the minimum performance standards for approved wetland alterations: a. Wetland functions improved over those of the original conditions. conditions will be restored as much as possible after construction, native shrubs and trees will be planted over areas disturbed by construction equipment, and the stormwater will be cleaner due to the removal of failing septic systems/elimination of fecal bacteria, the wetlands and their buffers are anticipated to have improved wetland functions (water filtration and habitat) post -project than they do currently. Proposed mitigation for temporary impacts are a mix of rehabilitation and enhancement methods. Mitigation monitoring will occur for five years after the initial planting inspection. A revised mitigation plan with performance schedules for plant survival and contingencies will be submitted once the construction areas are cleared and sites and species for tree replanting are identified. Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 10 b. Hydrologic conditions and hydroperiods are improved over existing conditions and the specific hydrologic performance standards specified in the approved mitigation plan are achieved. c. Acreage requirements for creation, re- establishment, rehabilitation or enhancement and for proposed wetland classes are met. d. Vegetation native to the Pacific Northwest is installed and vegetation survival and coverage standards over time are met and maintained. e. Habitat features are installed, if habitat is one of the functions to be improved. f. Buffer and bank conditions and functions exceed the original state. 3. Maintenance and monitoring of mitigation shall be done by the property owner for a period of no less than five years and for ten years when the mitigation plan includes establishing forested wetland and/or buffers. Maintenance shall be carried out in accordance with the approved mitigation plan. Monitoring reports must be submitted to the City for review with the frequency specified in the approved mitigation plan. F. WETLAND AND BUFFER MITIGATION LOCATION. 1. In instances where portions of a wetland or wetland buffer impacted by development remain, mitigation for buffer impacts shall be provided on -site. Where an essential public road, street or right-of-way or essential public utility cannot avoid reducing a buffer by more than 50%, additional buffer enhancement must be carried out at other locations around the impacted wetland. 2. On -site mitigation for wetland impacts shall be provided, except where the applicant can demonstrate that: a. On -site wetland mitigation is not scientifically feasible due to problems with hydrology, soils, waves or other factors; or b. Mitigation is not practical due to potentially adverse impact from surrounding land uses; or c. Existing functions created at the site of the proposed restoration are significantly greater than lost wetland functions; or d. Regional goals for flood storage, flood conveyance, habitat or other wetland functions have been established and strongly justify location of mitigation at another site. 3. Off -site mitigation shall occur within the same watershed where the wetland loss occurred. 4. Mitigation sites located within the Tukwila City limits are preferred. However, the Director may approve mitigation sites outside the city upon finding that: a. Adequate measures have been taken to ensure the non - development and long-term viability of the mitigation site; and b. Adequate coordination with the other affected local jurisdiction has occurred. All proposed mitigation will occur onsite, only in areas disturbed by construction equipment. Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 11 5. In selecting mitigation sites, applicants shall select a site in a location where the targeted functions can reasonably be performed and sustained and shall pursue sites in the following order of preference: a. Sites within the immediate drainage sub -basin; b. Sites within the next higher drainage sub -basin; and c. Sites within Green/Duwamish River basin. G. MITIGATION TIMING — Mitigation projects shall be completed prior to activities that will permanently disturb wetlands and either prior to or immediately after activities that will temporarily disturb wetlands. Construction of mitigation projects shall be timed to reduce impacts to existing wildlife, flora and water quality, and shall be completed prior to use or occupancy of the activity or development. The Director may allow activities that permanently disturb wetlands prior to implementation of the mitigation plan under the following circumstances: 1. To allow planting or re -vegetation to occur during optimal weather conditions; 2. To avoid disturbance during critical wildlife periods; or 3. To account for unique site constraints that dictate construction timing or phasing. 18.45.210 Assurance Device A. In appropriate circumstances, such as when mitigation is not completed in advance of the project, the Director may require a letter of credit or other security device acceptable to the City to guarantee performance and maintenance requirements of TMC Chapter 18.45. All assurances shall be on a form approved by the City Attorney and be equal to 150% of the cost of the labor and materials for implementation of the approved mitigation plan. B. When alteration of a sensitive area is approved, the Director may require an assurance device, on a form approved by the City Attorney, to cover the cost of monitoring and maintenance costs and correction of possible deficiencies for five years. In the event that more than five years monitoring and maintenance is required, the amount of security required will be for the first five years and years 7 and 10. If at the end of five years performance standards are not being achieved, an increase in the security device may be required by the Director. When another agency requires monitoring beyond the City's time period, copies of those monitoring reports shall be provided to the City. C. The assurance device shall be released by the Director upon receipt of written confirmation submitted to the Department from the applicant's qualified professional that the mitigation or restoration has met its performance standards and is successfully established. Should the mitigation or restoration meet performance standards and be successfully established in the third or fourth year of monitoring, the City may release the assurance device early. The assurance device Mitigation measures will occur post - construction. Construction will occur, then the ground restored to pre - construction conditions, then native plants will be planted in areas disturbed by the sewer infrastructure installation. As a public entity, the District is exempt from any requirement that they provide surety bonds for projects, including sewer installation. The first 3 years after tree planting are the most critical; during the initial 3 years a newly -planted tree will take root and adjust to the soil and growing conditions in the new environment. Typically, trees are watered during the dry season for the first three years after planting. The sensitive areas that will be disturbed for the sewer loop project are in undeveloped areas, far away from municipal water service connections; watering won't be an option. To address this concern, the planner and the District will seek to plant the replacement trees in shady areas whenever possible. Because the disturbed areas are wetlands and buffers, it is more than likely that retained soil moisture will be sufficient to establish good tree health Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 12 may be held for a longer period, if at the end of the monitoring period, the performance standards have not been met or the mitigation has not been successfully established. In such cases, the monitoring period will be extended and the bond held until the standards have been met. D. Release of the security does not absolve the property owner of responsibility for maintenance or correcting latent defects or deficiencies or other duties under law. and growing conditions for the initial three years after planting, the five-year monitoring period, and beyond. COMMENTS A Notice of Application was mailed on March 13th, 2018 to all property owners and tenants within 500' of the project boundaries. One person commented on the project (Attachment F) and two people requested to be parties of record for the project (Attachment G). A few others receiving postcards came to the front counter or called to get project information but did not request to be parties of record and did not submit comments for consideration. In addition to the City's Notice of Application process, Valley View Sewer District has led extensive outreach efforts including larger community meetings and individual meetings with homeowners to discuss the proposed project, hookup costs, and construction schedules. The outreach efforts undertaken by Valley View Sewer District have occurred over several years, from the concept stage through project design and financing. CONCLUSIONS 1. Sewer infrastructure (utility installation and maintenance) is a permitted use subject to administrative review and approval. The proposed sewer infrastructure routing has considered the presence of streams, wetlands and their buffers and the routing has been changed from the original design to minimize the disturbance of these sensitive areas. The project is consistent with TMC 18.45.070- Sensitive Area Permitted Uses. 2. The project routing and construction details protect the sensitive area and its buffer against erosion, uncontrolled storm water, restriction of groundwater movement, slides, pollution, habitat disturbance, any loss of flood carrying capacity and storage capacity, and excavation or fill detrimental to the environment. The project is consistent with TMC 18.45.090- Wetland Uses, Alterations, and Mitigation. 3. Wetlands and their buffers that will be disturbed by this project will be restored to pre- project configuration, replanted with native vegetation and provided with maintenance care until newly planted vegetation is established. With recommended condition #1, the proposal meets the requirements of TMC 18.45.090.D- Wetland Mitigation Plan Content. With the addition of native trees to the proposed mitigation plan, no Toss of habitat functions is anticipated because of this project. Several years after the sewer lines have been installed, the functioning of the wetlands and their buffers is anticipated to be increased due to enhanced water quality and native plantings, including trees, resulting from this project. The proposal is consistent with TMC 18.45.090.E- Mitigation Standards.

After the construction area has been cleared, sites for the planting of the 149 required replacement trees will be identified and revised planting plans submitted to the City. If not all replacement trees can be accommodated in the wetlands and wetland buffer spaces, the District will pay the in -lieu fee into the City's Tree Fund. The proposal is consistent with TMC 18.54- Tree Regulations. RECOMMENDATIONS Staff recommends approval of the Special Permission permit allowing the installation of sewer lines (essential utilities) in wetlands and wetland buffers with the following conditions: 1. After the construction area has been cleared, sites for the planting of the 149 required replacement trees will be identified and revised planting plans submitted to the City. If not all replacement trees can be accommodated in the wetlands and wetland buffer spaces, the District will pay the in -lieu fee into the City's Tree Fund. Valley View Sewer District and City of Tukwila Planning staff will walk the project site once it has been cleared for the sewer pipe installation and identify the locations where replacement trees will be planted after construction is finished and the land restored to pre -development grades. These tree species and their locations will then be marked on revised Mitigation/Planting Plans (Sheets 47-50 of Attachment D) and submitted for city's approval. 2. Mitigation monitoring will occur for 5 years from mitigation acceptance by the City. Yearly monitoring reports shall be submitted to the City by November 30th of the monitoring year. The City shall then conduct annual inspections to ensure performance standards are being met.

January 2018 PROJECT AND SITE DESCRIPTION The Valley View Sewer District (District) is proposing to extend sewer to an area of Tukwila within the District's service area currently served by septic systems. The area is referred•to as -the Loop. The proposed sewer system extension would construct approximately 12,000 linear feet (If) of 6- and 8-inch gravity sewer by open cut, 1,6001f of 6- and 8-inch gravity sewer by horizontal directional drill, 6001f of 1.5- and 2-inch sewer force main, 7 individual pump stations, 50 manholes, and 20 cleanouts. The project provides the opportunity for connection to 145 existing homes and provides future connections for full development under existing zoning. Water sampling has documented fecal coliform (FC) bacteria in drainages present downstream of the project area. FC counts above 200 colony forming units (CFU) per 100 milliliters (mL) are considered unsafe for direct contact. Readings as high as 4,900 CFU/100 mL have been documented in this area. The Loop area is one of the last remaining unsewered pockets in the District's service area. During application for project funding from the Clean Water State Revolving Fund (SRF) in October 2015, administered by the Washington State Department of Ecology (Ecology), the Loop project was ranked third out of 150 applications submitted statewide for water quality improvement. This signifies a great need for implementation of the project and construction of sewers in this unsewered area. In subsequent SRF application in the fall of 2017, the Loop project received full funding because of the established need for sewers in this area. The project site is located entirely within Tukwila city limits. It is bordered by State Route (SR) 518 to the north, 42nd Avenue South to the west, 48th Avenue South to the east, and South 160th Street to the south. Sewer will be constructed within public rights -of -way (ROW) and private utility easements. SENSITIVE AREA ORDINANCE COMPLIANCE The northern end of the project contains several wetland areas, as well as two Type Ns streams, delineated by Sewall Wetland Consulting, Inc. (Sewall) in February and April of 2016, and January and October of 2017. Due to constraints of the project area, sewer mains will be partially routed through the three wetlands and their associated buffers. Methods have been employed in the design and alignment of the proposed sewer to avoid and minimize impacts to wetlands and streams where possible, as well as limiting construction around wetland areas. These efforts have resulted in avoidance of the northern lobe of Wetland A/B, Wetland Z, and the two Type Ns stream; and minimization of impacts to the southern lobe of Wetlands A/B, C, X, and 2. Directional drilling is proposed beneath the east Type Ns stream and associated Wetland 2, which will avoid and minimize impacts to that sensitive area. The impacts to wetlands and buffers due to sewer construction will be fully restored upon project completion; thus, these impacts are considered temporary only. Tree and shrub removal in wetlands, buffers and associated streams is proposed to be replaced through wetland restoration efforts. Since 1 1/9/2018 4:18 PM J:\DATA\VSD\1 I5-005\SW LOOP (CODD-TAPIO) AND TUKWILA LOOP SEWER\PERMITTING\TUKWILA-LOOPLOOP PROJECT NARRATIVE FOR SPDA.DOCX 'r r` i • 1 •t.1 Valley View Sewer District Project Narrative for SPDA The Loop Sewer Extension Project January 2018 replacement vegetation will be directly over the installed sewer line, species have been limited to native shrubs and small trees. Trees proposed for removal in critical areas have been documented in the attached Tree Removal in Critical Areas spreadsheet. No permanent impacts are anticipated. The extent of impacts to wetland and buffer areas and a plan for restoration have been detailed by Sewall in a Critical Areas Report and Restoration Plan. Per Tukwila Municipal Code (TMC) 18.45.070(B)(5), essential utilities are permitted uses in a sensitive area only after administrative review and approval by the Director, and must demonstrate compliance with the provisions of that title. Any alteration to a wetland is subject to the additional requirements of TMC 18.45.090(B). Compliance with these requirements is addressed as follows. Response to Decision Criteria TMC 18.45.070(B)(5) — Permitted Uses Sanitary sewers will be constructed in a manner that minimizes disturbance to wetlands and their buffers. Construction of sewers will primarily utilize open cut methods; trenching through wetlands and their buffers will be minimized by limiting excavation to the width of a standard excavator (10 feet on either side of the proposed sewer main trench, for a total of 20 feet wide). Similarly, the impact area for manhole installation will be limited to a 20-foot-wide square surrounding the proposed structure. The sewer alignment has been modified where possible to route open cut trenching outside of the wetland boundary. Work will be conducted in the dry season, minimizing impacts to natural stormwater and groundwater movement, reducing erosion, and mitigating landslide risk. Native soil will be stockpiled outside of the wetlands and their buffers and replaced in the same location and grade as pre -disturbance conditions. While slope wetlands already have minimal flood carrying and storage capacity, impacts are further minimized by restoring pre -disturbance grades. Upon completion of sewer installation, the wetlands and their buffers will be restored to pre -project condition or better, replanted with native plants, and provided with maintenance care until newly planted vegetation is established. By installing native plants in the place of non-native invaders, a functional uplift of habitat in the wetlands and their buffers is anticipated. No permanent impacts are expected; therefore, no additional mitigation is proposed. TMC 18.45.090(B) — Alterations to Wetlands Only temporary alterations to wetlands for sewer utility installation are proposed. The alteration will not adversely affect water quality; in fact, the completed project is expected to benefit water quality by removing septic systems in the project area, which are a known source of environmental contaminants when improperly located and/or maintained. The wetlands are located in an urbanized area and habitat functions are low; fish, wildlife, and their habitat will not be adversely affected. The project will not have an adverse effect on drainage and/or stormwater detention capabilities. Surfaces will be restored to pre -construction elevations and no additional impervious surfaces are proposed. The project will not lead to unstable earth conditions, create an erosion hazard, or contribute to scouring actions. A Trenchless Feasibility Technical Memorandum (Staheli Trenchless Consultants, May 2017) and Engineering Geology Technical Memorandum (RH2 Engineering, Inc., January 2017) for the project area provide geotechnical investigation findings and recommendations for reducing the risk of impacts to soil stability. The project will not be materially detrimental to any other property and will not have adverse effects on any other sensitive area. 1 /9/2018 4:18 PM SPDA.DOCX 2 J:\DATA\VSD\115-005\SW LOOP (GOOD-TAPIO) AND TUKWILA LOOP SEWER\PERMITTING\TUKWILA-LOOP\LOOP PROJECT NARRATIVE FOR 1106„,, 8111 January 5, 2018 Dana Dick Valley View Sewer District PO Box 69550 Seattle, Washington 98168 Sewall Wetland Consulting, Inc.

Field observations The majority of the Loop sewer system goes through existing roads, yards and developed areas. The only natural area is located along the north edge of the Loop within several private parcels and the property owned by WSDOT. As depicted on the attached Existing Conditions map, there are four wetlands as well as two streams passing through this section of the project. Below is a description of these critical areas; Wetland A/B 86 X A single emergent and scrub -shrub wetland was observed in the study area crossing over the proposed alignment in three areas. These areas were delineated with flags A1-A8, B1-B4 and X1-X11 and XX1-XX10. The western lobe is a sloping emergent wetland dominated by reed canary grass and some bamboo. This section is located within a highly disturbed area where a demolished home is located. An old decorator pond is located just upslope of the wetland and water from this pond appears to seep out on the hillside creating wetland conditions. This water seeps northerly through the wetland to a roadside ditch along the south side of SR518. Valley View Loop/# I 5-161 Sewall Wetland Consulting, Inc. January 5, 2018 Page 6 The eastern lobe is located just north of an abandoned shed and consists of a seeping hillside vegetated with sitka willow and Himalayan blackberry. The narrow portion delineated as Wetland X appears to be a swale like feature that formed alongside an old overgrown logging road. Soil pits excavated within the wetland revealed a saturated clay -loam with low chroma (10YR 2/1 ) and redoximorphic concentrations. Using the US Fish and Wildlife Wetland Classification Method (Cowardin et al. 1979), this wetland would be classified as PEM1E and PSS1E. Using the 2004 revised WADOE Wetland Rating system and rating the wetland as a slope type wetland, this wetland scored a total of 31 points with 13 for habitat. This indicates a Category III wetland. According to Tukwila Municipal Code (TMC) 18.45.080.C, Category III wetlands have an 80' buffer measured from the wetland edge. Using the 2014 WADOE Wetland Rating system and rating the wetland as a slope type wetland, this wetland scored a total of 14 points with 3 for habitat. This indicates a Category IV wetland.

January 5, 2018 Page 10 WETLAND "2" CATEGORY IV WETLAND 50FT BUFFER A single, intermittent stream was identified along the WSDOT land south of SR 518. The ordinary high water mark of the stream was flagged with blue flagging labeled E1-E4 and W1-W5. This stream drains down a moderately steep slope to the north in a braided channel before going over the bank into the drainage ditch system along SR518. The channel is approximately 4' in width and has a mix of mud and gravel bottom and was observed flowing approximately 1" deep during our site visit. This stream is not mapped or classified in any inventory system. Due to small size, apparent intermittent flow, and steep portion (>15% slope) to the north, this channel does not appear to support any fish species. This stream best meets the criteria of a Type Ns stream based upon WDFW classification. Using the criteria in TMC 18.45.100.A, this stream best meets the criteria of a Type 4 Watercourse due to intermittent flow Valley View Loop/#15-161 Sewall Wetland Consulting, Inc. January 5, 2018 Page 11 and lack of fish use. Type 4 watercourses have a 50' buffer measured from the ordinary high water. East Stream A small intermittent channel originates in a seep below an existing single family home on the far eastern end of the project approximately 100' east of Wetland #2. This stream flows in a dug ditch type channel to the north from a seep located in dense blackberry and drains into the asphalt lined trough which drains east and then under the WSDOT access road in a 12" cmp. This stream is not mapped or classified in any inventory system. Due to small size, apparent intermittent flow, and steep portion (> 15% slope) to the north, this channel does not appear to support any fish species. This stream best meets the criteria of a Type Ns stream based upon WDFW classification. Using the criteria in TMC 18.45.100.A, this stream best meets the criteria of a Type 4 Watercourse due to intermittent flow and lack of fish use. Type 4 watercourses have a 50' buffer measured from the ordinary high water. Proposed Project The proposed project is the construction of sewer extensions to service numerous homes in this area that are currently on septic systems which are degrading water quality in wetlands and streams in the area. Avoidance and minimization Due to locations of existing sewer lines as well as acquired easements and existing topography, there is very little variation from the proposed alignment that is possible that would result in a functional sewer line. As a result it is impossible to avoid impacting wetlands and their buffers completely. Due to the required location of the alignment for proper flow and function, some unavoidable temporary impacts to Wetland A/B/X/Z, Wetland C and Wetlands #2 will occur during the construction. The impacts include 1,066sf of impact to Wetland A/B, 1,256sf to Wetland X, 62sf of Wetland C and 16sf to Wetland #2. These impacts are temporary; Valley View Loop/#15-161 Sewall Wetland Consulting, Inc. January 5, 2018 Page 12 no there are no permanent impacts. In addition, 17,505sf of wetland buffer will be temporarily impacted as well. WETLAND & BUFFER IMPACT SUMMARY 1,066 SF - WETLAND A/B 62 SF - WETLAND C 1,256 SF - WETLAND X 16 SF - WETLAND 2 2,386 SF - TOTAL TEMPORARY WETLAND IMPACT 17,505 SF - TOTAL WETLAND BUFFER IMPACT There is no way to avoid these impacts and construct the project. In order to minimize impacts the portion of the line that will be near the Type 4 Watercourse will be bored under the stream and its associated 50' buffer. No impacts to the stream or buffer will occur The portions of the line through Wetland A/B, C, and X and their associated buffers have been minimized to the width of a standard excavator. The line will need to be constructed with an open trench. This work will be conducted in the dry season. After placement of the line, native soil that has been stockpiled outside the wetland and its buffer will be replaced in the same location and grades as the wetland prior to disturbance. The area near Wetland #2 will be bored and will result only in a small impact to the wetland and buffer. The area will then be replanted with a mix of native plants as depicted on the attached "Critical Areas Restoration Plan for the Loop Sewer". The area will then be monitored for 5 years as required by Code. There is no permanent road or path through the alignment. Access for monitoring and maintenance will be on foot through the easement. The restored areas plantings will be within a dense forest canopy that should provide sufficient shade to allow the plantings to survive despite not having irrigation. There is no water source to allow irrigation to be used. If plants appear stressed during the monitoring period hand watering could be utilized if needed. Valley View Loop/#15-161 Sewall Wetland Consulting, Inc. January 5, 2018 Page 13 Due to the fact that the plantings are being installed over a sewer line, no trees were utilized in the restoration plan as the roots of trees can interfere with utility lines such as this. US Army Corps and WDFW Permits It is probable a Section 404 Nationwide Permit will be required for the proposed impacts to Wetlands from this project. In addition, it is possible an HPA will be required from WDFW to bore under the Type Ns stream (Type 4 Watercourse) as well. The Corps and WDFW should be consulted to determine if these permits will be required.

If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the spatial characteristics found in the wetland. SPI. Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered attinsal or plant species (T/E species)? For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category I Natural Heritage Wetlands (seep. 19 of data form). SP3. Does the wetland unit contain indtviduals of Priority species listed by the WDFW for the state? / SP4. Does the wetland unit have a local significance in addittcrr to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydrogeomorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands.

YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system arc called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Gro r and surface water runoff are NOT sources of water to the unit. O YES - The wetland class is Flats our wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; st 30% of the open water area is deeper than 6.6 fl (2 m)? NO - to 4 YES - The wetland class is Lake -fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ,The wetland is on a slope (slope can be very gradual), water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being Impounded?

Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding NO - go to 6 YES - The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clues. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a dpressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit classify the wetland using the class that represents more than 90s/o of the total area. ?' >YxN'n'''m.'".'r" mn 1'4.0'?",^ .•.7r.;el•: Y'et ',4'.^/ -�e:..Yaf :S p. c. � 'at�' .."Ir :'.na�ri.: .

Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlanda have changed (see p. ). 2.

NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding NO - go to 6 YES - The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressions! 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM closes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit, classify the wetland using the class that represents more than 90% of the total area.

NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 YES - The wetland class is RIverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland NO - go to 7 YES - The wetland class is Depresslonal 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depresstonal 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM closes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide).

Are the water levels in the entire unit usually controlled by tides except during floods? ENO - go to YES - the wetland class is Tidal Fringe - go to 1.1 1.1 is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and Is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit Is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. YES - The wetland class is Flats r wetland can be classified as a Flats wetland use the form for Depressional wetlands 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland Is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; .......At least 30% of the open water area is deeper than 6.6 ft (2 m). NO - 0 4 Yes- The wedand class is Lake Fringe (Lacustrine Fringe) 4. Do to entire wetland unit meet all of the following criteria? wetland is on a slope (slope can be very gradual), _- Th ter flows through the wedand in one direction (unidirectional) and usually comes from eps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, _- The water leaves the wetland without being Impounded. NO - go to 5 -The wetland class e NOTE: Surface water does not pond in these type of wetla • c • - . nay in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective lanuary 1. 2015 3 Wetland name or number (41-- NO - go to 6 YES - The wedand class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression In which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet if present is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few Inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wedand class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate lass to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. if the area of the HGM lass listed in column 2 is less than 10% of the unit; classify the wetland using the lass that represents more than 90% of the total area.

This means that any outlet, If present is higher than the interior of the wetland NO - go to 7 YES - The wetland class is Depresslonal 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depresslonal 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM Basses. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depresslonal wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to Identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM lass listed in column 2 1s less than 10% of the unit; classify the wetland using the lass that represents more than 90%of the total area. ` 10g1. daaaesw$ iln_the:wegaOQt Mt ! bNri[ rat ' t'f t}.to • Sae Windt* Slope • Riverine Riverine Slope + Depressional Depresslonal Slope + Lake Fringe Lake Fringe Depresslonal + Riverine along stream within boundary of depression Depresslonal Depresslonal + Lake Fringe Depresslonal Rlverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland or Ifyou have more than 2 HGM daises within a wetland boundary, classify the wetland as Depresslonal for the rating.

Are the water levels In the entire unit usually controlled by tides except during floods? YES - the wetland class is Tidal Fringe - go to 1.1 e salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. if it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to It. Groundwater and surface water runoff are NOT sources of water to the unit. YES - The wetland class is Flats d can be classified as a Flats wetland, use the form for Depresslonal wetlands 3. Does the entire wetland unit meet all of the following cnteria? _The vegetated part of the wetland Is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; __,At-leest10%o of the open water area is deeper than 6.6 ft (2 m). (JO - go to 4 YES - The wetland class is Lake Fringe (lacustrine Fringe) 4. D e entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), water flows through the wetland in one direction (unidirectional) and usually comes from seps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impoynded- - -•-_ :.\` NO - go to 5 YES - The wetland class is Slo e NOTE: Surface water does not pond in these type of wetlands ecxe p oiT aslonaily in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 3 Wetland name or number NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depresslonal 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depresslonal 8. Your wedand unit seems to be difficult to classify and probably contains several different HGM lasses. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNiT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that Is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is Jess than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

The improvements will bring gravity sewer service to approximately 138 residential lots currently using on -site septic systems. The Tukwila Loop Sewers project consists of constructing 3,500 feet of 6-inch-diameter and 8,500 feet of 8-inch-diameter polyvinyl chloride (PVC), and 150 feet of 6-inch and 420 feet of 8-inch-diameter high density polyethylene (HDPE) gravity sewer at depths ranging from 8 to 12 feet below ground surface (bgs) constructed in open -cut excavations. The project also includes approximately 1,500 feet of 8-inch-diameter HDPE gravity sewer constructed using directional drilling methods. Seven lots would be served with individual pump stations and approximately 570 feet of 1.5-inch-diameter I /I1/2018 3:20 PM J.\Dan\VSD \115-005\SV1' Loop (Codd-Tapio) and Tukwila Loop Scu'cr\Gco\Tech ?Icmo rc I.nop Gcotechnical Grabaacon.docs Technical Memorandum RE: Engineering Geology Review January 11, 2018 Page 2 force mains. In addition, 47 48-inch-diameter concrete manholes would be completed at depths ranging from 8 to 16 feet bgs (Figure 1). This technical memorandum summarizes the geologic, groundwater and geotechnical conditions, and geologic hazards of the project site, which includes a review of available geologic information and geotechnical site explorations related to the project. Constructing the project would likely encounter a variety of geologic conditions, ranging from loose sand and silty sand (glacial outwash and glacial lakebed sediment) to very dense sandy silt with gravel (glacial till). Little groundwater is expected to occur in open excavations or directional drill borings. Construction using open trenches likely would require trench boxes and groundwater control to stabilize the open excavations. Trenchless methods may require excavations at both ends of the segment of pipe installed by horizontal directional drilling (HDD). Location and Existing Conditions The site is located in Tukwila, Washington, just south of State Route (SR) 518 west of its intersection with Interstate 405 at the north end of a ridge between SeaTac Airport to the west and Southcenter valley to the east. The project area generally slopes downward to the north, is benched or undulating, and ranges in elevation of approximately 435 feet above mean sea level (AMSL) (North American Datum of 1983) along S 160`h Street to elevation 300 feet AMSL at the north end of 44`h Place S (Figure 1). The site and surrounding area are developed for residential use. SITE INVESTIGATION Exploration Methods and Strategy RH2 reviewed available geologic maps compiled by the Washington State Department of Natural Resources (WADNR), soil maps published by the Natural Resources Conservation Service (NRCS), and drillers' logs for the local area stored on the Washington State Department of Ecology (Ecology) well log database. RH2 reviewed available geologic and geotechnical investigations by Shannon and Wilson, Inc. (S&W, 1968) on behalf of WSDOT in support of the design and construction of SR 518. Four soil borings were completed in the northern portion of the project site (S&W, 1968). RH2 reviewed the findings of two geotechnical site investigations conducted by Earth Solutions NW, LLC. (ESNW) in March and June, 2017, which consisted of six soil borings (labeled B 1 to B3 and B l * to B3*, respectively) to depths of 26.5 feet bgs (ESNW, 2017a; ESNW, 2017b). RH2 reviewed the findings and recommendations of a technical memorandum regarding the feasibility of trenchless construction for a portion of the gravity sewer (Staheli Trenchless Consultants, 2017). 1/11/2018 3:20 PM J:\Dam\VSD\115-005\SW Loop (Cold- Papio) and Tukwila Coop Seiner\Gcu\Tech Memo ro Loop Gcorcchnical Evaluarion.docs Technical Memorandum RE: Engineering Geology Review January 11, 2018 Page 3 RH2 conducted a site reconnaissance along the northeast, east, and southeast perimeter of the project area to observe soil, geologic, and groundwater conditions, and to inspect the area for indications of landslide risk. Figure 1 shows the site layout and the locations of the soil borings completed in the project area. Boring logs from ESNW (2017a, 2017b) are attached. INTERPRETATION, ANALYSIS, AND EVALUATION OF SITE GEOLOGY Geologic Units The project site is underlain by several distinct geologic units, as illustrated on Figure 1. Glacial Till — Dense to very dense, silty sand with gravel and cobbles, generally moist, no stratification, thin zones of groundwater seepage. Cobble size typically ranges from 2 to 4 inches, but could contain occasional boulders 6 to 18 inches in diameter. Glacial Advance Outwash — Dense sand with silt and silty sand, moist to wet, stratified, may contain groundwater bearing zones. Glacial Recessional Outwash — Loose to dense sand with silt, silty sand, and sandy silt, moist to wet, stratified, may contain groundwater bearing zones. Glacial Lacustrine Silt — Soft to stiff or hard silt and sandy silt, moist, stratified, may contain groundwater bearing zones. These units mapped by WADNR are shown as general locations in the project area (Figure 1). The lateral boundaries between the units are imprecise and irregular. Observations of septic drainfield failure and subsurface utility construction generally confirm the soil and moisture characteristics; septic systems have failed in areas of low permeability glacial till and lacustrine silt, and septic systems are functioning as designed in areas of permeable outwash units. Soil borings completed in the project area generally encountered loose to dense sand, silty sand, and sand, which were identified as either recessional or advance glacial outwash (ESNW, 2017a; ESNW, 2017b). Groundwater Conditions Groundwater was observed at B1 and B2 (ENSW, 2017a; Figure 1) and described as minor seepage or perched groundwater within permeable zones encountered during drilling. The groundwater zones entering the borings generally occurred at depths below 7 feet bgs. The borings were drilled in March 2017, and the seepage may indicate seasonally elevated groundwater levels during late winter -early spring. No groundwater was observed in the three upland borings B1*, B2*, and B3* (ENSW, 2017b; Figure 1). Actively flowing natural springs exist to the east of the project area, as shown on Figure 1. The source of water discharging from Crystal Springs is likely precipitation falling on the uplands above the project site, which then migrates into the outwash and moves laterally to a zone of groundwater discharge.

Landslide Risks at the Site Mapping by S&W (1968) on behalf of WSDOT identified recent scarps north of and below the project site, and an apparent "prehistoric [more than 10,000 years ago] slide scarp" near the north limits of the project site (Figure 1). The recent scarps appear to be small shallow soil/colluvium slides common to landslide prone areas along steep slopes in the Puget Sound lowlands, and were likely triggered through excavation for borrow material and excavation for SR 518 (S&W, 1968). The prehistoric scarp appears to be defined as the transition from gentle to steep slopes at the north end of the project area. WADNR has not mapped any slide areas for the project area in the current statewide landslide database. RH2 inspected the northeast, east, and southeast borders of the project area for indications of historic and active landslide conditions. The area is densely vegetated, and wetlands and persistent seeps are scattered about the area. There were no indications of recent soil slides or slumps, no indications of tilted or "pistol -butted" trees demonstrating slow soil creep, and no indications of hummocky soil, soil cracks, or other topographic features suggesting soil movement. In contrast, S&W (1968) described significant landslide features and recent shallow slides on the slopes approximately 50 feet lower in elevation and 200 to 300 feet in horizontal distance from the edge of the project area. The greatest landslide risk along the northeast, east, and southeast borders of the project area likely consist of persistent seepage of groundwater discharging from slopes that tend to weaken soil strength and lead to small soil slides. WSDOT installed a continuous 10- to 20-foot-deep drain along the WSDOT right of way, just north of the project area boundary, and installed multiple 100- to 400-foot-long horizontal drains into the underlying sand units below the slope between the project area and SR 518 to collect and convey groundwater seepage from the slope to mitigate slide risk (S&W, 1968). WSDOT also removed soil from the same slope, regraded/flattened the slope, and covered the slope with a quarry spall rock blanket to facilitate drainage off the slope. The conversion of 138 homes from on -site septic wastewater discharge to off -site wastewater transfer and treatment mitigates much of the landslide risk in the project area. Assuming that each home discharges on average 200 gallons per day to a septic drainfield, approximately 11 million gallons of water per year will be collected and conveyed away from the site instead of infiltrating into the shallow soil of the project area. The effluent from drainfields currently recharges the shallow groundwater system below the project area, and this groundwater ultimately discharges downgradient of the project area to the north and northeast towards the steep slopes between the project area and SR 518. Construction of the sewer mains using open -cut excavation methods will not alter the topography or loading of the soil on the site. Equivalent weight materials will be used to backfill the 4-foot-wide trenches used to install the gravity sewers. l/11/20183:20001 ):\ Data \\'SD\IIS-005\SW Ioop (Codd-Tapio) and Tukwala Ioop Sewer \Gco\Tech 0tcrno re loop Gcocechnical Evalaanon_doca Technical Memorandum RE: Engineering Geology Review January 11, 2018 Page 5 Construction of the sewers using open -cut excavation methods may alter the hydrology of the project area by creating subsurface utility trenches that in some areas may be more permeable than surrounding soil and may convey infiltrated precipitation along the utility trenches. Constructing trench dams in the excavated trenches to detain infiltrated water would allow the water to drain deeper into underlying soil. Constructing drainage outlets that route trench water to surface stormwater collection would mitigate any risk that the utility trenches might have on increasing the moisture content and groundwater volumes in the project area. Construction of the gravity sewer using trenchless methods will not substantially alter the hydrology of the project area. The borehole constructed for the gravity sewer would be constructed with low permeability mud, and the same mud will surround the annular space between the borehole and gravity sewer upon completion. Natural Geologic Hazards and Risks at the Site • The risks of landslides and mass wasting affecting the construction and operation of the project are low in the central and southern portions of the project area, and low to moderate in the northern portions of the project area. • The risk of flooding from ephemeral creeks and swales is low; most of the area is served by a stormwater collection system that discharges collected stormwater away from the project area. • The risk of groundwater seepage into open excavations deeper than 5 feet and affecting the construction of the project is low in areas mapped as underlain by glacial till, and moderate in areas mapped as underlain by glacial outwash. RECOMMENDATIONS FOR DESIGN AND EARTHWORK OF THE PROJECT Approach The gravity sewer and manholes will be constructed in 6- to 15-foot-deep excavations cut into a variety of native granular soil, ranging from dense to very dense sandy silt with gravel (glacial till), loose to dense sand and silty sand, and firm to stiff silt. These soil types may be excavated using backhoe and tracked excavators. An occasional large boulder or layer of loose running sand may be encountered in the excavations. Trenchless construction, depending on the method, likely will encounter loose to dense sand and silty sand that is moist to wet, and stratified. Horizontal directional drilling (HDD) likely would be the suitable method for installing HDPE gravity sewer, which would not require excavating jacking and receiving pits to facilitate construction. Conditions Likely Encountered During Construction Gravity sewer excavations in areas underlain by glacial outwash may encounter stratified layers with occasional groundwater bearing zones that could affect the rate of excavation or dewatering requirements. Soil conditions are generally consistent at the site exploration locations along the northern perimeter of the project area. 1 /11/2018 3:20 PM J:\Data\VSD\11 5-005\SW Loop (Cold Tapio) and Tukwila Loop Sewer \Geo\Tech Mcrno rc Loop Gcotcchnical Evilnauon.doc, Technical Memorandum RE: Engineering Geology Review January 11, 2018 Page 6 There were no observed conditions (large boulders, highly variable stratification or density) that suggested the infeasibility of tunneling or boring, but some variability in soil grain size and occasional cobbles and boulders should be expected that could affect the rate or methods for areas scheduled for trenchless construction (Staheli Trenchless Consultants, 2017). Although not observed, there is a possibility that larger cobbles and boulders may exist in excavations for gravity sewer installation in the upland areas of the project underlain by glacial till. Open -cut Excavation Most of the gravity sewer and manholes would be constructed using open -cut excavation methods requiring shoring and occasionally groundwater control to maintain the excavation. Based on the relatively narrow width of trench excavations, the moderately cohesive and moist fine-grained soil, and the loose to very dense soil conditions, shoring likely would be accomplished using trench boxes to maintain the integrity of open -trench excavations. The type and methods for shoring should be designed by the contractor, as necessary, to protect workers inside excavations and support temporarily excavated slopes. All excavations should comply with all Occupational Safety and Health Administration (OSHA) and Washington Industrial Safety and Health Act (WISHA) safety requirements. Groundwater Control in Open Excavations Excavations below depths of 5 to 7 feet bgs may encounter zones or lenses of perched groundwater or groundwater -saturated conditions. Installation of shallow vacuum wellpoints may be necessary in a few of the deepest excavations in glacial outwash soil if groundwater sump pumps cannot maintain dry conditions in the excavations; however, for most of the project, groundwater control for trench excavations may be effectively maintained using one or more groundwater sump pumps inside the excavation, as these short excavations will not be open for extended periods. Trench dewatering rates could range from 5 to 25 gallons per minute (gpm), depending on the length and depth of the open excavation. Discharged groundwater should not be allowed to collect on the site or to run off the site. Groundwater discharge should be managed through settlement and filtering so that it is free of sediment and does not exceed discharge limits at the point of discharge. Trenchless Methods Installing the sewer using trenchless methods would require designing an approach that would maintain the required grade. Recommendations for the approach and risks of trenchless methods are summarized by Staheli Trenchless Consultants, Trenchless Feasibility Technical Memorandum, Loop Sewer Project, Valley View Sewer District (May 2017). 1/11/2018 Sao PM J:\Datawslw l5-005\sr' Loop (Cod,i T,pio) and Tukwila Loop Sower \GcoTech Memo m Loop Gcumchnic:J Ev:duation.doas Technical Memorandum RE: Engineering Geology Review January 11, 2018 Page 7 Excavation to the Subgrade • Excavation for the sewer and manholes may be readily accomplished with typical excavation equipment capable of reaching a depth of 15 feet bgs. • Excavation should proceed until a uniformly dense surface that is free of organic material has been cut into the native soil at or below the design depth. Excavated soil use • Excavated soil from areas underlain by glacial outwash may be used for excavation trench backfill in areas not underlain by pavement and not in the City of Tukwila Right of Way if the soil is free of organic material, contains less than 10 percent fines, and is maintained at an optimum moisture content. Native soil replaced in the excavations should be placed in 6-inch lifts, and compacted with a plate compactor or equivalent. Each lift should be compacted to a firm and unyielding surface to achieve 92 percent of maximum dry density (MDD), as determined by the modified proctor test (American Society for Testing and Materials (ASTM) D1557). • Excavated soil from areas underlain by glacial till and glacial lacustrine silt are not likely suitable for reuse at the site due to the high percentage of silt and/or large cobbles. Inspection and Treatment of In -situ Earth • Site inspection by a Licensed Engineering Geologist (LEG) or Professional Engineer with geotechnical experience (PEG) during excavation is recommended to evaluate whether the native soil exposed during excavation is consistent with the site conditions described in this technical memorandum and favorable for proceeding with the project as planned. • Once the excavations have attained final subgrade depth, the excavated surface should be tested by probing, if accessible, inspected for soil composition and quality, and approved by a qualified inspector before placement of pipe bedding or structures. Subgrade Preparation and Structural Backfill Placement and Compaction • Any structural fill used to replace loose or soft native soil, or otherwise unsuitable material at the subgrade, and structural fill used to replace native soil in excavations, should meet the requirements of Select Borrow, 9-03.14(2) in WSDOT 2018 Standard Specifications Manual 41-10, or equivalent, placed in 6-inch lifts, and compacted with a plate compactor or equivalent. Each lift should be compacted to a firm and unyielding surface to achieve 95 percent of MDD, as determined by the modified proctor test (ASTM) D1557. • Structural fill should be within plus or minus 2 percent of its optimum moisture content when placed.

Gravity Sewer Pipe -zone Backfill • Pipe -zone backfill should envelop the gravity sewer completely and should consist of crushed surfacing top course (CTSC) or 5/8-inch minus; placement and compaction should follow Pipe Bedding, 7-08.3(1)C in WSDOT 2018 Standard Specifications Manual 41-10. Trench Excavation Backfill • Trench excavation backfill placement and compaction should follow Trenches, 7-08.3(1)A in WSDOT 2018 Standard Specifications Manual 41-10. • All imported structural fill material (other than CSBC) should be inspected to confirm that composition and moisture content are within an acceptable range, just prior to placement. • In areas underlain by glacial outwash, trench dams may be used to detain infiltrated water and minimize downslope conveyance of trench water. • In areas underlain by glacial till, use of trench dams should be designed to minimize potential accumulation of water behind the trench dams; in certain favorable areas, trench drains should be placed to allow trench water to discharge to stormwater or sewer systems. Trench Excavation Restoration • The trench excavations could become areas where precipitation could infiltrate into deeper soil and migrate along trenches. Where feasible, trench excavations should be restored at the surface to minimize infiltration into the trench using low permeability amendments to soil, and the surface should be contoured to convey surface water away from the backfilled trench and into the stormwater system.

The only natural area is located along the north edge of the Loop within several private parcels and the property owned by WSDOT. As depicted. on the attached Existing Conditions map, there are four wetlands as well as two streams passing through this section of the project. Below is a description of these critical areas; Wetland. A/B & X A single emergent and scrub -shrub wetland was observed in the study area crossing over the proposed alignment in three areas. These areas were delineated with flags A1-A.8, Bl-B4 and Xl-X11. and XX1.-XX10. The western lobe is a sloping emergent wetland dominated by reed canary grass and some bamboo. This section is located within a highly disturbed area where a demolished home is located.. An old decorator pond is located just upslope of the wetland and water from this pond. appears to seep out on the hillside creating wetland conditions. This water seeps northerly through the wetland to a roadside ditch, along the south side of SR51.8. Valley View Loop/ti I 5-161 Sewall Wetland Consulting, Inc. January 5, 2018 Page 6 The eastern lobe is located just north of an abandoned shed and consists of a seeping hillside vegetated with sitka willow and Himalayan blackberry. The narrow portion delineated as Wetland X appears to be a swale like feature that formed alongside an old overgrown logging road. Soil pits excavated within the wetland revealed a saturated clay -loam. with low chrorna. (10YR 2/1. ) and red.oximorphic concentrations. Using the US Fish and Wildlife Wetland Classification Method (Cowardin et al. 1.979), this wetland would be classified as PEM:1E and PSS1E. Using the 2004 revised WADOE Wetland Rating system and rating the wetland as a slope type wetland, this wetland scored a total of 31 points with 13 for habitat. This indicates a Category III wetland. According to Tukwila Municipal Code (TMC) 18.45.080.C, Category in wetlands have an 80' buffer measured from the wetland edge.

January 5, 2018 Page, 10 WETLAND "2" CATEGORY IV WETLAND 5OFT BUFFER A single, intermittent stream was identified along the WSDOT land south. of SR 518. The ordinary high water mark of the stream was flagged with blue flagging labeled El.-E4 and WI-W5. This stream drains down a moderately steep slopeto the north in a. braided channel before going over the bank into the drainage ditch, system along SR51.8. The channel is approximately 4' in width and has a mix of mud and gravel bottom and was observed flowing approximately. 1" deep during our site visit. This stream is not mapped or classified in any inventory system. Due to small size, apparent intermittent flow, and steep portion (>15% slope) to the north, this channel does not appear to support any fish species. This stream best meets the criteria of a Type Ns stream based upon WDFW classification. Using the criteria in TMC 18.45.100.A, this stream best meets the criteria of a Type 4 Watercourse due to intermittent flow Valley View Loop/# 15-161 Sewall Wetland Consulting, Inc. January 5, 2018 Page 11 and lack of fish use. Type 4 watercourses have a 50' buffer measured from the ordinary high water. East Stream A small intermittent channel originates in a seep below an existing single family home on the far eastern end of the project approximately 100' east of Wetland #2. This stream flows in a dug ditch type channel to the north from a seep located in dense blackberry and drains into the asphalt lined trough which drains east and then under the WSDOT access road in a 12" cmp. This stream is not mapped or classified in any inventory system. Due to small size, apparent intermittent flow, and steep portion (>15% slope) to the north, this channel does not appear to support any fish species. This stream best meets the criteria of a Type Ns stream based upon WDFW classification.

Type 4 watercourses have a 50' buffer measured from the ordinary high water. Proposed Project The proposed project is the construction of sewer extensions to service numerous homes in this area that are currently on septic systems which are degrading water quality in wetlands and streams in the area. Avoidance and minimization Due to locations of existing sewer lines as well as acquired easements and existing topography, there is very little variation from the proposed alignment that is possible that would result in a functional sewer line. As a result it is impossible to avoid impacting wetlands and their buffers completely. Due to the required location of the alignment for proper flow and function, some unavoidable temporary impacts to Wetland A/B/X/Z, Wetland C and Wetlands #2 will occur during the construction. The impacts include 1,065sf of impact to Wetland A/B, 1,523sf to Wetland X, 70sf of Wetland C and 16sf to Wetland #2. These impacts are temporary; Valley View Loop/#15-161 Sewall Wetland Consulting, Inc. January 5, 2018 Page 12 no there are no permanent impacts. In addition, 24,055sf of wetland buffer will be temporarily impacted as well. WETLAND & BUFFER IMPACT SUMMARY 1,065 SF - WETLAND A/B 70 SF - WETLAND C 1,523 SF - WETLAND X 16 SF - WETLAND 2 2,674 SF - TOTAL TEMPORARY WETLAND IMPACT 24,055 SF - TOTAL WETLAND BUFFER IMPACT There is no way to avoid these impacts and construct the project. In order to minimize impacts the portion of the line that will be near the Type 4 Watercourse will be bored under the stream and its associated 50' buffer. No impacts to the stream or buffer will occur The portions of the line through Wetland A/B, C, and X and their associated buffers have been minimized to the width of a standard excavator. The line will need to be constructed with an open trench. This work will be conducted in the dry season. After placement of the line, native soil that has been stockpiled outside the wetland and its buffer will be replaced in the same location and grades as the wetland prior to disturbance. The area near Wetland #2 will be bored and will result only in a small impact to the wetland and buffer. The area will then be replanted with a mix of native plants as depicted on the attached "Critical Areas Restoration Plan for the Loop Sewer". The area will then be monitored for 5 years as required by Code. There is no permanent road or path through the alignment. Access for monitoring and maintenance will be on foot through the easement. The restored areas plantings will be within a dense forest canopy that should provide sufficient shade to allow the plantings to survive despite not having irrigation. There is no water source to allow irrigation to be used. If plants appear stressed during the monitoring period hand watering could be utilized if needed. Valley View Loop/# 15-161 Sewall Wetland Consulting, Inc. January 5, 2018 Page 13 Due to the fact that the plantings are being installed over a sewer line, no trees were utilized in the restoration plan as the roots of trees can interfere with utility lines such as this. US Army Corps and WDFW Permits It is probable a Section 404 Nationwide Permit will be required for the proposed impacts to Wetlands from this project. In addition, it is possible an HPA will be required from WDFW to bore under the Type Ns stream (Type 4 Watercourse) as well. The Corps and WDFW should be consulted to determine if these permits will be required.

For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. co SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category I Natural Heritage Wetlands (see p. 19 of data form). / SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? / SP4. Does the wetland unit have a local significance in adc tiar to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hvdrogeomorphic Class of the wetland being rated The hdrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. Sec p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Fonn - western Washington 2 version 2 Updated with new WDFW definitions Oct 2008 August 2004 4 Wetland name or number _ Classification of Wetland Units in Western Washington 1. Are the wait r 1e\ Is in the entire unit usually controlled by tides (i.e. except during floods)? ego to YES - the wetland class is Tidal Fringe f yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES- Freshwater Tidal Fringe NO - Salhrater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and tI estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Grou dastcr and surface water runoff are NOT sources of water to the unit. YES - The wetland class is Flats our wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; st 30% of the open water arca is deeper than 6.6 fl (2 m)? N to 4 YES - The wetland class is Lake -fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? /The wetland is on a slope (slope can be very gradual), .?he water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions cr behind hummocks (depressions are usually <3) 4,rreteranettess thmr-1 NO - go to 5 t YES - The wetland class is Slo Wetland Rating Form - western Washington 3 version 2 Updated with new WDFW definitions Oct 2008 August 2004 Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding NO - go to 6 YES - The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit scems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine tloodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit, classify the wetland using the class that represents more than 90% of the total area.

For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part pi -the data sheet you will need to determine the NYdrogeomorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands.

YES— Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. nd surface water runoff are NOT sources of water to the unit. YES — The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; east 30% of the open water area is deeper than 6.6 fl (2 m)? \ NO 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe) 4.

Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 YES — The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland NO — go to 7 YES — The wetland class is Depressions] 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO — go to 8 YES — The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressions] wetland has a zone of flooding along its sides. CrO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydrogeomorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands.

YES — Freshwater Tidal Fringe NO — Saltwater Tidal !hinge (Estuarine) If your wetland con be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system arc called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire and unit is flat and precipitation is the only source (>90%) of water to it. surface water runoff are NOT sources of water to the unit.

Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. NO - go to 6 YES — The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland NO — go to 7 YES — The wetland class is Depressional 7. Ls the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO — go to 8 YES — The wetland class is Depressions! 8. Your wetland unit seems to be difficult to classify and probably contains several different HOM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depresslonal 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide).

The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depresslonal 8. Your wedand unit seems to be difficult to classify and probably contains several different HGM Basses. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along tts sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED iN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS iN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM dass listed in column 2 is less than 10% of the unit; classify the wetland using the Bass that represents more than 90% of the total area.

Are the water levels in the entire unit usually controlled by tides except during floods? YES - the wetland class is Tidal Fringe - go to 1.1 e salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? N0 - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe !f your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. !fit is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. YES - The wetland class is Flats nd can be classified as a Flats wetland use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; . 4eest30 of the open water area is deeper than 6.6 ft (2 m). �JO - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. D e entire wetland unit meet all of the following criteria? .....The wetland is on a slope (slope can be very gradual), _•,‘ifie water flows through the wetland in one direction (unidirectional) and usually comes from seeeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, _The water leaves the wetland without being impo,Rnded7------ NO - go to 5 •.. YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except -occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 3 Wetland name or number 2 NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a nverne floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED iN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. lithe area of the HGM lass listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90S'6 of the total area. r a Nia�If�C ,we'th tthlgwetland 0., r? t �) ..N, c_`r,;> _ ' betnfaiedr",.. 14, ., ' .... . r l .

January 2018 PROJECT AND SITE DESCRIPTION f E C r r a, r D JAN 2 6 2C 3 The Valley View Sewer District (District) is proposing to extend sewer to an area of Tukwila( � within the District's service area currently served by septic systems. The area is referre t as)theit Loop. The proposed sewer system extension would construct approximately 12,000 linear feet Of) of 6- and 8-inch gravity sewer by open cut, 1,6001f of 6- and 8-inch gravity sewer by horizontal directional drill, 6001f of 1.5- and 2-inch sewer force main, 7 individual pump stations, 50 manholes, and 20 cleanouts. The project provides the opportunity for connection to 145 existing homes and provides future connections for full development under existing zoning. Water sampling has documented fecal coliform (FC) bacteria in drainages present downstream of the project area. FC counts above 200 colony forming units (CFU) per 100 milliliters (mL) are considered unsafe for direct contact. Readings as high as 4,900 CFU/100 mL have been documented in this area. The Loop area is one of the last remaining unsewered pockets in the District's service area. During application for project funding from the Clean Water State Revolving Fund (SRF) in October 2015, administered by the Washington State Department of Ecology (Ecology), the Loop project was ranked third out of 150 applications submitted statewide for water quality improvement. This signifies a great need for implementation of the project and construction of sewers in this unsewered area. In subsequent SRF application in the fall of 2017, the Loop project received full funding because of the established need for sewers in this area. The project site is located entirely within Tukwila city limits. It is bordered by State Route (SR) 518 to the north, 42nd Avenue South to the west, 48th Avenue South to the east, and South 160th Street to the south. Sewer will be constructed within public rights -of -way (ROW) and private utility easements. SENSITIVE AREA ORDINANCE COMPLIANCE The northern end of the project contains several wetland areas, as well as two Type Ns streams, delineated -by Sewall Wetland Consulting, Inc. (Sewall) in February and April of 2016, and January and October of 2017. Due to constraints of the project area, sewer mains will be partially routed through the three wetlands and their associated buffers. Methods have been employed in the design and alignment of the proposed sewer to avoid and minimize impacts to wetlands and streams where possible, as well as limiting construction around wetland areas. These efforts have resulted in avoidance of the northern lobe of Wetland AB, Wetland Z, and the two Type Ns stream; and minimization of impacts to the southern lobe of Wetlands AB, C, X, and 2. Directional drilling is proposed beneath the east Type Ns stream and associated Wetland 2, which will avoid and minimize impacts to that sensitive area. The impacts to wetlands and buffers due to sewer construction will be fully restored upon project completion; thus, these impacts are considered temporary only. Tree and shrub removal in wetlands, buffers and associated streams is proposed to be replaced through wetland restoration efforts. Since 1 1/9/2018 4:18 PM J:\DATA\VSD\115-005\SW LOOP (CODD-TAPIO) AND TUKWILA LOOP SEWER \PERMITTING\TUKWILA-LOOP\LOOP PROJECT NARRATIVE FOR SPDA.DOCX Valley View Sewer District Project Narrative for SPDA The Loop Sewer Extension Project January 2018 replacement vegetation will be directly over the installed sewer line, species have been limited to native shrubs and small trees. Trees proposed for removal in critical areas have been documented in the attached Tree Removal in Critical Areas spreadsheet. No permanent impacts are anticipated. The extent of impacts to wetland and buffer areas and a plan for restoration have been detailed by Sewall in a Critical Areas Report and Restoration Plan. Per Tukwila Municipal Code (TMC) 18.45.070(B)(5), essential utilities are permitted uses in a sensitive area only after administrative review and approval by the Director, and must demonstrate compliance with the provisions of that title. Any alteration to a wetland is subject to the additional requirements of TMC 18.45.090(B). Compliance with these requirements is addressed as follows. Response to Decision Criteria TMC 18.45.070(B)(5) — Permitted Uses Sanitary sewers will be constructed in a manner that minimizes disturbance to wetlands and their buffers. Construction of sewers will primarily utilize open cut methods; trenching through wetlands and their buffers will be minimized by limiting excavation to the width of a standard excavator (10 feet on either side of the proposed sewer main trench, for a total of 20 feet wide). Similarly, the impact area for manhole installation will be limited to a 20-foot-wide square surrounding the proposed structure. The sewer alignment has been modified where possible to route open cut trenching outside of the wetland boundary. Work will be conducted in the dry season, minimizing impacts to natural stormwater and groundwater movement, reducing erosion, and mitigating landslide risk. Native soil will be stockpiled outside of the wetlands and their buffers and replaced in the same location and grade as pre -disturbance conditions. While slope wetlands already have minimal flood carrying and storage capacity, impacts are further minimized by restoring pre -disturbance grades. Upon completion of sewer installation, the wetlands and their buffers will be restored to pre -project condition or better, replanted with native plants, and provided with maintenance care until newly planted vegetation is established. By installing native plants in the place of non-native invaders, a functional uplift of habitat in the wetlands and their buffers is anticipated. No permanent impacts are expected; therefore, no additional mitigation is proposed. TMC 18.45.090(B) — Alterations to Wetlands Only temporary alterations to wetlands for sewer utility installation are proposed. The alteration will not adversely affect water quality; in fact, the completed project is expected to benefit water quality by removing septic systems in the project area, which are a known source of environmental contaminants when improperly located and/or maintained. The wetlands are located in an urbanized area and habitat functions are low; fish, wildlife, and their habitat will not be adversely affected. The project will not have an adverse effect on drainage and/or stormwater detention capabilities. Surfaces will be restored to pre -construction elevations and no additional impervious surfaces are proposed. The project will not lead to unstable earth conditions, create an erosion hazard, or contribute to scouring actions. A Trenchless Feasibility Technical Memorandum (Staheli Trenchless Consultants, May 2017) and Engineering Geology Technical Memorandum (RH2 Engineering, Inc., January 2017) for the project area provide geotechnical investigation findings and recommendations for reducing the risk of impacts to soil stability. The project will not be materially detrimental to any other property and will not have adverse effects on any other sensitive area. 1 /9/2018 4:18 PM SPDA.DOCX 2 J:\DATA\VSD\115-005\SW LOOP (CODD-TAPIO) AND TUKWILA LOOP SEWER\PERMITTING\TUKWILA-LOOP\LOOP PROJECT NARRATIVE FOR • CITY OF TUKWILA Department of Community Development 6300 Southcenter Boulevard Tukwila, WA 98188 Telephone: (206) 431-3670 SPECIAL PERMISSION - DIRECTOR INFORMATION The Tukwila Zoning Code and Sign Code have established "Special Permission" decisions, which are more complex than straightforward applications of code standards, but do not require a public hearing.

Planning Division Staff are available to discuss the decision criteria you must respond to and necessary supporting materials. PARKING DEVIATION • Covenant Parking: where required parking is provided off -site (TMC 18.56.070(B)); • Complementary Parking: where up to 10% of a development's useable floor area is determined to be linked to remaining area, such that it need not provide the normally required parking (TMC 18.56.070(D)); • Reduction of the minimum required parking of up to 10%, through an administrative variance (TMC 18.56.140). A parking reduction may be allowed after: 1. All shared parking strategies are explored. 2. On -site park and ride opportunities are fully explored. 3. The site is in compliance with the City's commute trip reduction ordinance or, if not an affected employer as defined by the City's ordinance, agrees to become affected. 4. The site is at least 300 feet away from a single-family residential zone. 5. A report is submitted providing a basis for less parking and mitigation necessary to offset any negative effects. In addition to the above requirements, the Director may require specific measures not listed to ensure that all impacts with reduced parking are mitigated. Any spillover parking that cannot be mitigated to the satisfaction of the Director will serve as the basis for denial. LANDSCAPE DEVIATIONS • The landscape perimeter may be averaged if the total required square footage is achieved, unless the landscaping requirement has been increased due to proximity to LDR, MDR or HDR. Landscape perimeter averaging may be allowed as a Type 2 special permission decision if all of the following criteria are met: 1. Plant material can be clustered to more effectively screen parking areas and blank building walls. 2. Perimeter averaging enables significant trees or existing built features to be retained. 3. Perimeter averaging is used to reduce the number of driveways and curb cuts and allow joint use of parking facilities between neighboring businesses. 4. Width of the perimeter landscaping is not reduced to the point that activities on the site become a nuisance to neighbors. 5. Averaging does not diminish the quality of the site landscape as a whole. • In the MDR and HDR zones up to 20% of the minimum required front yard landscaped area may be developed for pedestrian and transit facilities. • In the RCC and TUC zones required landscaping may include a mix of plant materials, pedestrian amenities and features, outdoor cafe -type seating and similar features. Required plant materials will be reduced in proportion to the amount of perimeter area devoted to pedestrian oriented space. \\deptstore\City Common\Teri\Revisions In Progress\Special Permission Director -March 2011.docx 3-4-11 SENSITIVE AREA ORDINAL` ,. — Deviations, Alterations or Uses Requiring rdministrative Review and Approval • Setbacks TMC 18.45.080(E) and TMC 18.45.100(D). All commercial and industrial developments shall be set back 15 feet and all residential development shall be set back ten feet, measured from the foundation to the buffer's edge. The Director may waive setback requirements when a site plan demonstrates there will be no impacts to the buffer zone from construction or occasional maintenance activities. • Buffer Reductions TMC 18.45.080(F) and TMC 18.45.100(E). (Please note, no buffer reduction is permitted where the buffer consists of undisturbed, native vegetation.) The Director may reduce the standard wetland/watercourse buffers on a case -by -case basis, provided the buffer does not contain slopes 15% or greater. Under certain circumstances, a buffer reduction may be considered for property with slopes less than 15% (see TMC 18.45.080(F) and 18.45.100(E)). The approved buffer width shall not result in greater than a 50% reduction in width. Any buffer reduction proposal must demonstrate to the satisfaction of the Director that it will not result in direct or indirect, short-term or long-term adverse impacts to wetlands or watercourses, and that: 1. Additional protection to wetlands will be provided through the implementation of a buffer enhancement plan; 2. The existing condition of the buffer is degraded; 3. Buffer enhancement includes, but is not limited to the following: (a) Planting vegetation that would increase value for fish and wildlife habitat or improve water quality; (b) Enhancement of wildlife habitat by incorporating structures that are likely to be used by wildlife, including wood duck boxes, bat boxes, snags, root wads/stumps, birdhouses and heron nesting areas; or (b) Removing non-native plant species and noxious weeds from the buffer area and replanting the area subject to TMC 18.45.080(F)(2)(c)(1). • Uses Requiring Administrative Review and Approval The following uses may be permitted only after administrative review and approval by the Director — see TMC 18.45.070(B) or TMC 18.45.110(B) for additional guidance: 1. Maintenance & repair of existing uses/facilities where additional fill will be placed or heavy equipment used; 2. New surface water discharges to a sensitive area; 3. Placement of bioswales and dispersion outfalls in a wetland or watercourse buffer; 4. Enhancement or other mitigation including landscaping with native plants; 5. Construction of essential utilities; 6. Construction of new essential public streets, roads and rights of way; 7. Public or private use and access; 8. Dredging, digging or filling in a sensitive area or its buffer; 9. Removal of hazardous trees from a sensitive area; 10. Transfer of wetland mitigation to a wetland mitigation bank (TMC 18.45. 090(E)) or other off -site mitigation. • Alterations Requiring Administrative Review and Approval by the Director (TMC 18.45.090(B), TMC 18.45.110(B)). 1. Piping, rerouting or diverting a watercourse 2. Any alteration to a sensitive area or its buffers, including vegetation removal, or alterations to wetlands less than 1,000 sq. ft. (see TMC 18.45.090(B)(5)); 3. Approval of a Sensitive Area Master Plan or any alteration to an approved Sensitive Area Master Plan \\deptstore\City Common\Teri\Revisions In Progress\Special Permission Director -March 2011.docx 3-4-11 CARGO CONTAINERS Approval criteria for cargo containers to be installed in the LDR, MDR, and HDR zones for institutional uses and in the RC, RCM, TUC or C/LI zones for permitted or conditional uses: • Only two cargo containers will be allowed per lot, maximum length 40 feet. • The container is located to minimize the visual impact to adjacent properties, parks, trails and rights -of -way as determined by the Director. • The cargo container is sufficiently screened from adjacent properties, parks, trails and rights -of -way, as determined by the Director. Screening may be a combination of solid fencing, landscaping, or the placement of the cargo containers behind, between or within buildings. • If located adjacent to a building, the cargo container must be painted to match the building's color. • Cargo containers may not occupy any required off-street parking spaces. • Cargo containers shall meet all setback requirements for the zone. • Outdoor cargo containers may not be refrigerated. • Outdoor cargo containers may not be stacked. SINGLE-FAMILY DESIGN STANDARD EXCEPTIONS The design standards required at 18.50.050 (5) and (6) may be modified by the DCD Director. • The criteria for approval of a roof pitch flatter than 5:12 are as follows: 1. The proposed roof pitch is consistent with the style of the house (for example modern, southwestern); 2. If a flat roof is proposed, the top of the parapet may not exceed 25 feet in height; 3. If a sloped roof is proposed, it must have at least 24-inch eaves; and 4. The house exhibits a high degree of design quality, including a mix of exterior materials, detailing, articulation and modulation. • The criteria for approval of a house with a front door that faces the side or rear yard are as follows: 1. The topography of the lot is such that pedestrian access is safer or more convenient from the side or rear yard; 2. The house will be set back at least twice the minimum front yard setback; 3. The entrance is oriented to take advantage of a site condition such as a significant view; or 4. The entry feature is integral to a unique architectural design. \\deptstore\City Common\Teri\Revisions In Progress\Special Permission Director -March 2011.docz 3-4-11 „, ,,,'/„i///' ,//, ,ri ,,,,//„///ri/, „/,ri„i„ ,r„,„//rr"/; / // //rri//'„' ,r'///r//r iri//,"r / a L„', r,/„• //// „° ,e/ ,r / "/ / / r• /r/ rr ,ri rir /O%90/G�r�i//%/.///O%OJ/L//G/D///O/////L//d0//%////O/%✓�i/L✓6�✓///G//OU,�LL/!%!O/rr///%%/O�/6/JU/UG//r,4 r //r. ,i,/d/4 40U//rOU //l //l////l/1,%////////////,.00�///%%/%%/ ,// / //, / / / / / / / ,/ / / /%/%//Ol%/O/////�%/%O///%/O///////%///O//O/O/O/O/l%l/%O//l0/O%// /�///O//%D/%/,///i/O/D//O/////l/O,/////%%%l/////,////////%O/O/// //%//////, / / // / / / � // / /i / % //O/////////D///////////,,/,% //////%/ /%%/%/ /////////%%/////////%/Ol/O//////O/O///////,.///////////%/////////%/////i///O///r//,%/////////�/%%%/////00//i/////%%/0//////O///%%//////i/O//r%%///O% //////////O/,/////%%///% *PI FIROJII'f„ T SITE /;,/�� „ //,,,/r///////�0%�/%/�/�i//%/ol///,////%%/OQ//Oj f/rb,///01/, ,/I,r,g///0/ ,,I;lliJe,r�0 l %Ir/44.” %i/ 'yi / 1 / / f / � / %oil% / PROJECT VICINITY MAP KING COUNTY TUKWILA, WA /" J '-/ / / , / / / r �;",/�/ /r, �,,.,alb/////ii�//ii/////l„�„/�Te////%i/%T////,l///%%/////////1/O///%D%O//////////////////%r/l/GJ/,////////%%iT2,/�///„?�% Buren Normandy Park I�'lu�ll4 uu�w�r¢ i Y " L 'r.p�iwo V UmmN111111 L 111vg11111111111111111111111,1,1111111111 I, r;Sr;!F'M ION Marcor Island Newcastle Valley View Sewer District Project Manager RH2 Engineering Project Manager RH2 Engineering Project Engineer RH2 Engineering Project Engineer Dana Dick John Hendron, P.E.

' IN ADDITION TO DESCRIBING AS -BUILT CONDITIONS, BASELINE MONITORING DATA SHALL BE COLLECTED AND PERMANENT PHOTO POINTS SHALL BE ESTABLISHED TO DOCUMENT REPRFSF.NTATIVE CONDITIONS WITHIN EACH RI STORATION AREA. BASELINE MONITORING DATA COLLECTED AND REPORTED AS PART OF THE A5 BUILT SHALL BE CONSISTENT WITH THAT DESCRIBED FOR "ANNUAL MONITORING" (SEE BELOW). THE AS -BUILT REPORT AND BASELINE MONITORING DATA SHALL BE SUBMITTED TO THE CITY OF TUKWILA NO IATER THAN 30 DAYS FROM THE DATE THAT THE WORK SHOWN ON THIS PLAN HAS BEEN COMPLETED. ANNUAL MONITORING - 5 YEARS: ANNUAL COMPLIANCE MONITORING SHALL BE COMPLETED BY A QUALIFIED PROFESSIONAL AND SHALL COMPRISE A SITE INVESTIGATION IN AUGUST OR SEPTEMBER AND REPORTING TO THE CITY OF TUKWILA NO LATER THAN 30 DAYS FOLLOWING EACH MONITORING ASSESSMENT. THE MONITORING TERM 155 YEARS. THE PURPOSE OF EACH MONITORING ASSESSMENT IS TO EVALUATE CONDITIONS WITHIN THE RESTORATION AREA PER THE CURRENT YEAR'S PERFORMANCE STANDARDS. THE FOLLOWING INFORMATION SHALL BE COLLECTED AND ASSESSED RELATIVE TO THE PERFORMANCE STANDARDS ESTABLISHED FOR THE PROJECT: • THE PERCENT SURVIVAL OF INSTALLED PLANT STOCK (YEARS 1, 2, & 3). A DIRECT COUNT INVENTORY AND ASSESSMENT OF ALL INSTALLED PLANTS SHALL BE USED TO EVALUATE PERCENT SURVIVAL. THE RATIONALE FOR POOR CONDITIONS, IF PRESENT, WILL BE DETERMINED TO THE EXTENT FEASIBLE. • THE PERCENT COVERAGE PROVIDED BY INSTALLED PLANT SPEOES (ALL YEARS). INSTALLED PLANT STOCK PERCENT COVERAGE SHALL BE ASSESSED USING APPROPRIATELY SIZED SAMPLE PLOTS OR LINE INTERCEPT TRANSECTS. • THE SPECIES COMPOSITION OF AND PERCENT COVERAGE PROVIDED BY NOXIOUS WEED SPECIES (ALL YEARS). SPECIES COMPOSITION AND PERCENT COVERAGE BY NOXIOUS WEEDS SHALL BE ASSESSED USING SAMPLE PLOTS OR LINE INTERCEPT TRANSECTS. IN ADDITION, PHOTOGRAPHS OF BUFFER AREAS SHALL BE TAKEN FROM THE PERMANENT PHOTO POINTS ESTABLISHED DURING THE AS -BUILT. THE RESULTS OF EACH MONITORING ASSESSMENT SHALL BE SUMMARIZED IN A WRITTEN REPORT AND SUBMITTED TO THE OTY OF TUKWILA NO LATER THAN 30 DAYS FOLLOWING EACH MONITORING ASSESSMENT. CONTINGENCY PLAN SHOULD ANY MONITORING ASSESSMENT REVEAL THAT THE PERFORMANCE STANDARDS FOR THE RESPECTIVE YEAR ARE NOT SATISFIED, THE PERMITTEE SHALL WORK WITH THE CITY OF TUKWILA TO DEVELOP A CONTINGENCY PLAN TO ADDRESS THE DEFICIENCY(IES). CONTINGENCY PLANS CAN INCLUDE, BUT ARE NOT LIMITED TO, THE FOLLOWING ACTIONS: 1) ADDITIONAL PLANT INSTALLATION; 2) EROSION CONTROL; 3) HERBIVORY PROTECTION; 4) MODIFICATION TO THE IRRIGATION REGIME; AND/OR 5) PLANT SUBSTITUTIONS OF TYPE, SIZE, QUANTITY, AND LOCATION. SUCH CONTINGENCY PLAN SHALL BE SUBMITTED TO THE CITY OF TUKWILA BY JANUARY 31 OF ANY YEAR WHEN DEFICIENCIES ARE DISCOVERED.
