Your letter raised concerns regarding tree clearing and wetland filling on the site and some questions regarding an existing fence. In light of your comments and other information on the site, the City made a request to the applicant to hire a wetland biologist and provide a wetland delineation and determination. The report, completed in January of this year, concluded that the fill placed on the site was not placed over wetland conditions on the property. A Technical Information Report was submitted with the application that indicates that during heavy rainfalls, stormwater on the site flows in a northerly direction towards a series of catch basins and underground pipes. The current City code does not regulate tree removal from private property unless the property has sensitive areas which this site does not. You also asked if the applicant would be moving the existing fence, which is located on his property, to your shared property line. Nothing in the application discusses the fence and the City does not require relocation of the fence. Fences six feet or less do not require a permit to erect. Aside from some very specific circumstances, an applicant is generally not limited as to where he may locate his fence on his property. I want to thank you for making your concerns known and taking the time to raise them with the City. Should you have further comments or questions, please do not hesitate to contact me at 206- 433 -7166.

The property is identified as King County Parcel No. 5537200116. The purpose of this work was to complete a site evaluation to make a determination if wetland conditions were present on the property prior to recent grading activity on the property. The scope of work included a site visit on November 18, 2008, at which time we completed our site observations. In completing the field work for the property I excavated a series of eight shallow test holes to depths up to 4.5ft using a post hole digger. I also reviewed aerial photographs from 1936, 1998, 2000, 2002, and 2005, which are available from the King County web site. The aerial photos were used to review historical conditions on the property. It is my understanding that there was recent grading activity on the property. The City of Tukwilla has requested additional information regarding possible wetland conditions on the property before the grading was completed. General Site Conditions The subject property is an irregularly shaped parcel of approximately 0.6 acre. It is located at 14213 33rd Avenue South in the City of Tukwilla. The location is illustrated on the Vicinity Map (Figure 1). There is an existing residence on the property with a gravel driveway providing access from 33rd Avenue South, near the northeast property corner. Adjacent properties to the north and west are occupied by single family residences. There is an apartment building with asphalt paving on the property to the south. Vegetation on the property includes several large Douglas fir (Pseudotsuga menziesii) trees around the existing residence. There is a line of trees including Douglas fir along the south property line between the apartment parking area and the subject property. There has been recent grading activity on the southern section of the 812 NE 83rd Street, Seattle, Washington 98115• Phone (206)334 -1338 email aldernw @comcast.net Mr. Beano Banakes January 20, 2009 • • property. Groundcover vegetation reflects the recent activity and is sparse across the property. Some lawn and landscaping surrounds the existing residence. There is no direct indication that there is wetland on nearby adjacent properties. There are standing Douglas fir trees along the south property line and adjacent properties to the east are occupied by maintained lawn and landscaping. Historical Aerial Photograph Review I reviewed aerial photographs which are available from the King County Web site. Photos taken in 1936, 1998, 2000, 2002, and 2005, are available for viewing at the web site. Photos from 1936, 2002, and 2005 are included with this report as Figures 1 through 5. Photos taken in 1998 and 2002 are available but they are of lower quality and it is difficult to see details on the subject property. Examination of the 1936 photo shows the property and surrounding lands to be in agricultural use. The existing house on the property is present. Roads surrounding the property had been constructed at the time of the 1936 photo. The photos do not show indications of wetland conditions on the property or in the immediate vicinity. Conditions on the subject property appear similar in the 2002 and 2005 photos. There appears to be a mix of shrub and herbaceous groundcover on the property and the house appears to have been added to. The apartment building and asphalt parking had been constructed prior to the 1998 aerial photo. While the quality of the image is low, conditions on the property appear similar to that shown on the 2002 photos. It is not possible to identify the species composition of the vegetation across the property. There is no indication of wet surface conditions on the property in the photos. There is some indication that there may have been some grading activity on the property before the 1998 photo. Soil Conditions The King County Soil maps do not cover the Tukwilla area and therefore do not provide information regarding soil conditions on the property prior to any recent grading activity. I excavated a series of 8 shallow test holes on the property at locations indicated on the attached Site Map (Figure 5). In general, conditions encountered in the test holes are similar at each of the locations. At each of the locations, there was a change in soil conditions at depths of 24" to about 36" below the surface. Surface soils were generally brown sandy soils with inclusions of wood bits and other debris. Soils below this surface soil, and extending to the depth explored were generally gray or dark gray and were more dense than the overlying soils. The lower soils also included wood pieces and some debris indicating the presence of fill. The distinct change in soil conditions indicate that there had been two grading events on the property. Soils to the depth excavated were generally wet to moist. There was no free water or saturated soils present. Observations of the near surface conditions, as observed in the test holes indicate that recent grading activity on the property placed up to about 36" of soil on the property. Below the most recently placed fill soils, there is older Project No. 111108 Page No. 2 Mr. Beano Banakes January 20, 2009 • • fill material which extends to depths below the depth of the test holes. This observation of an earlier level of fill is generally consistent with conditions observed in the aerial photographs. Based on the results of my review of historical record available from the series of aerial photographs, and observations from the series of test holes excavated on the property, it is my conclusion, that the recent grading activity did not place fill over wetland conditions on the property.

Please find enclosed with this letter the revised TIR and SEPA checklist addressing your comments. Comments from the letter have been addressed below in bold. Environmentalist Review Comments: 1. Hire a qualified wetland biologist with training and experience in wetland determination and delineation to do the following: Garet Munger, a wetland biologist with AldersNW, was hired to perform a field study to determine the possible existence if wetlands on the property. His letter dated January 12, 2009 and full report outlining his findings is enclosed with this re- submittal package. a. Evaluate the presence of wetland hydrology in at least four sample locations, in accordance with the Washington State Wetlands Identification and Delineation Manual— particularly Section F for Atypical Situations. It will be necessary to reach the native soils beneath the fill material. The biologist should use the original site topography information as a guide to determine the location of the sample plots. A map should be presented showing the sampling locations. A total of eight shallow test holes were excavated across the site. These holes were excavated to depths of up to about 4.5 ft. These test holes indicated that there had been recent filling to depths of about 3ft over older fills. A map showing the !cation of the test holes is included with the report. No map of the original topography is available at this time. T H E C O N C E P T G R O U P • • Banakes Short Plat 01/19/09 Page 2 b. Evaluate the presence of hydric soil conditions in the native soils below the fill in the same sample locations. Although the applicant submitted results of a soil test from LabCor Portland Inc. in the Draft Technical Report, aside from the fact that no information is presented as to the location of the soil sample, this report does not provide the information needed to make the determination of the presence or absence of hydric soils. The soils below the recently placed fills do not show hydric soil characteristics. c. If hydric soil and hydrologic indicators are observed, an attempt should be made to determine the approximate boundaries of the former wetland and the estimated size of the former wetland. Observations indicate that the recent filling did not cover wetland. d. Obtain historic information about soil ponding, previous vegetation, and other factors that would contribute to a determination of the presence or absence of wetland. Examination of the aerial photos available from the King County Web site do not show definitive indication that there wetlands present before the recent grading activity. The aerial photo from 1938 shows that the property and immediately surrounding areas were in agricultural use. SEPA Checklist /Draft Technical Report Comments: 2. The soil classification (SEPA Checklist Environmental Elements, Earth) does not appear to be correct. Soils in this location have not been mapped by NRCS, as it is considered to be an urban area. The same incorrect classification is presented in the Draft Technical Report, page 1. Both the SEPA checklist and the TIR have been revised to state, `The United States Department of Agriculture Natural Resource Conservation Service (NRCS), did not map soils information in the project vicinity because it is an urban area. A soil sieve analysis was performed by LabCor Portland, Inc. The soil is categorized to be coarse sand." 3. The Draft TIR, page 2, states in Section 2 that "during heavy rainfall events, stormwater sheet flows in an easterly direction towards the drainage ditches on Military Road South" and in Section 3 that "during heavy rainfall events, stormwater from the property sheet flows in an northerly direction towards 34th Avenue South." The SEPA checklist, Section2. Water, c. Water Runoff, (1) lists the latter. Section 2 of the TIR has been revised to state, "During heavy rainfall events, stormwater from the property sheet flows in a northerly direction toward 34th Avenue South." The statement in Section 3 and the SEPA checklist are correct. No revisions made to those two areas. T H E C O N C E P T G R O U P • • Banakes Short Plat 01/19/09 Page I 3 4. The SEPA Checklist, Earth (e) estimates 65 cy of cut, 10 cy of fill while the TESC Plan, sheet EC1 of the TIR estimates 65 cy of cut and 550 cy of fill. The applicant has already placed 490 cy of fill on the site without a permit. The SEPA checklist has been revised to reflect the quantities stated on sheet EC1. Cut and fill quantities were estimated based on existing topographic information from the site survey. 5. Section 4, Infiltration Facility Design of the Draft TIR says that "soils are not conducive to infiltrating stormwater from roofs." The SEPA checklist, Section 3 Water, b. Ground, (1) states that "surface water will continue to infiltrate to native soils and /or sheet flow to its natural location of discharge." This is an area that allows infiltration; a perk test will be required with a building application. The SEPA checklist, Section 3b has been revised to state, "Surface water will continue sheet flow to its natural location of discharge along 34th Avenue South." Although infiltration is allowed in this area, infiltration trenches will not be proposed for the roof stormwater. We appreciate your assistance with this project. Please feel free to contact me if you have questions regarding this re- submittal. Sincerely, The Concept Group, Inc. Anna Nguyen, P.E.

We live on Lot 6 at the end of S. 142" Place directly behind the project. Our first concern is the removal of trees and raising the elevation of the project lot(s) to fill in a wetland will cause the majority of the rain on the project lot(s) to drain onto our now even lower lot, which is saturated in the rainy season as it is. We are concerned that what the developer has already done may cause flooding under our home and by building three homes on the project lot(s) would acerbate the problem. We are unsure what, if any, changes may take place regarding draining of rainwater in our yard and how that may affect our property, as I am sure you could understand our concern. Our second concern is an old wood fence that belongs to the original home on the existing lot where the project will be built. Our neighbors have been in their house since it was built in 1963, a year before ours home was built, and they stated that fence was there before our home was built and belonged to the house on the project lot(s). The fence is very old, not sturdy and needs to be replaced onto the recently surveyed property line which is 7 of the project lot(s) feet to west of its current location. We would like to find out if a new fence will be built to replace the old existing fence on the proper east line of our lot? Please feel free to contact us with any questions. Thank you.

Two neighbors to the project sent letters to the City during the SEPA comment period. Both letters (attached) raised concerns that, prior to placing fill at the site, a wetland was on the property. Additionally, the city's drainage maintenance supervisor, John Howat, has observed water 7 -10' deep on the property during heavy rains. In 1999, the city put a drainage pipe into the property in 1999 to deal with the overflow and in an attempt to control the flooding onto the neighboring property to the south. In light of this information, the city requires additional information regarding the presence of a former wetland to process this application. Our urban environmentalist reviewed the application and requests the following: 1. Hire a qualified wetland biologist with training and experience in wetland determination and delineation to do the following: a. Evaluate the presence of wetland hydrology in at least four sample locations, in accordance with the Washington State Wetlands Identification and Delineation Manual, particularly Section F for Atypical Situations. It will be necessary to reach the native soils beneath the fill material. The biologist should using the original site topography information as a guide to determine the location of the sample plots. A map should be presented showing the sampling locations.

If hydric soil and hydrologic indicators are observed, an attempt should be made to determine the approximate boundaries of the former wetland and the estimated size of the former wetland. d. Obtain historic information about soil ponding, previous vegetation, and other factors that would contribute to a determination of the presence or absence of wetland. The above information should be submitted to the City for evaluation. Comments on SEPA Checklist/Draft Technical Report Staff also noticed a number of inconsistencies and issues with the SEPA checklist and Draft Technical Information Report (Draft TIR). Please address the following comments. 2. The soil classification (SEPA Checklist Environmental Elements, Earth) does not appear to be correct. Soils in this location have not been mapped by NRCS, as it is considered to be an urban area. The same incorrect classification is presented in the Draft Technical Report, page 1. 3. The Draft TIR, page 2, states in Section 2 that "during heavy rainfall events, stormwater sheet flows in an easterly direction towards the drainage ditches on Military Road South" and in Section 3 that "during heavy rainfall events, stormwater from the property sheet flows in an northerly direction towards 34th Avenue South." The SEPA checklist, Section2. Water, c. Water Runoff, (1) lists the latter. 4. The SEPA Checklist, Earth (e) estimates 65 cy of cut, 10 cy of fill while the TESC Plan, sheet ECI of the TIR estimates 65 cy of cut and 550 cy of fill. The applicant has already placed 490 cy of fill on the site without a permit. 5. Section 4, Infiltration Facility Design of the Draft TIR says that "soils are not conducive to infiltrating stormwater from roofs." The SEPA checklist, Section 3 Water, b. Ground, (1) states that "surface water will continue to infiltrate to native soils and/or sheet flow to its natural location of discharge." This is an area that allows infiltration; a perk test will be required with a building application.

Because two neighbors have reported that the site had wetland where the fill was placed, I think investigation is warranted. It is possible that a wetland existed in the low spot on the property, even if it was maintained as lawn. In order to evaluate the presence of the wetland the owner needs to hire a qualified wetland biologist with training and experience in wetland determination and delineation to do the following: 1. Evaluate the presence of wetland hydrology in at least four sample locations, in accordance with the Washington State Wetlands Identification and Delineation Manual, particularly Section F for Atypical Situations. It will be necessary to reach the native soils beneath the fill material. The biologist should using the original site topography information as a guide to determine the location of the sample plots. A map should be presented showing the sampling locations. 2. Evaluate the presence of hydric soil conditions in the native soils below the fill in the same sample locations. Although the applicant submitted results of a soil test from LabCor Portland Inc. in the Draft Technical Report, aside from the fact that no information is presented as to the location of the soil sample, this report does not provide the information needed to make the determination of the presence or absence of hydric soils. 3. If hydric soil and hydrologic indicators are observed, an attempt should be made to determine the approximate boundaries of the former wetland and the estimated size of the former wetland. 4.

Be specific in describing the types of changes you want made to the plans. When referencing codes, please identify the actual requirement and plan change needed. The Planning Division review does not supplant each department's ability to administer its own regulations and permits. However, project consistency at the Planning review stage is important to minimize significant later design changes. More than minimal design changes require further Planning Commission review, even if alteration is required to satisfy a City requirement. This further review is typically a minimum 60 -day process. Requirements based on SEPA (e.g., not required by an adopted development regulation) MUST identify the impact being mitigated, the policy basis for requiring mitigation, and the method used to calculate the mitigation required. Calculations of project impacts and the mitigation required (e.g., water capacity, road level of service analyses, or turning analyses) may be required of the applicant.

This report is based on limited subsurface exploration. During construction, if soils conditions are found that are significantly different from those identified in this report, construction should stop until those items affected by the changed conditions can be identified and adjusted, if needed to reflect the changed conditions. 3. This report is prepared for the sole use of client for the purpose of subdividing the property located at 14213 — 34th Avenue South in Tukwila, Washington. All other uses are expressly prohibited without prior written approval from the engineer. 4. All construction related to the drainage system for this project will be in accordance with the 1998 King County Surface Water Design Manual and the City of Tukwila current standards unless specifically mentioned in this report and /or approved by the City of Tukwila. Banakes Short Plat - Preliminary TIR January 2009 SECTION 1: PROJECT OVERVIEW The property is located at 14213 — 34th Avenue South in the City of Tukwila, Washington. There is currently one (1) single family residence on the property. The project proposes to short plat the existing parcel into three (3) single family residential lots. The existing house will remain. Proposed improvements include the construction of two (2) single - family structures, a Private Access /Utility tract, associated utilities and stormwater management facilities. Site Information Refer to Appendix A for the Vicinity Map and site photos of this project. Location: 14213 — 34th Avenue South; Tukwila, Washington 98003 Section/Township /Range: SW 'A of SW 'A Sec. 15, T.23N, R.4E of W.M. Size: 24,227 sq ft (approximately 0.56 acre) City, County, State: Tukwila, King County, Washington Governing Agency: City of Tukwila Design Criteria: 1998 King County Surface Water Manual Water District: #125 Sewer District: Valley View Drainage Basin The entire property drains to one basin with a contributing area of 0.56 acres. The general topography of the site slopes from south to north. Elevations on the site vary from a high point of 360 feet at the southern property line to 356 feet at the northern property line, with grades varying from 4.0% to 10.0 %. Soils Information Soils Survey The United States Department of Agriculture Natural Resource Conservation Service (NRCS), did not map soils information in the project vicinity because it is an urban area. A soil sieve analysis was performed by LabCor Portland, Inc. The soil is categorized to be coarse sand. Refer to Appendix B for the sieve analysis. The Concept Group Page 1 Banakes Short Plat - Preliminary TIR January 2009 SECTION 2: CONDITIONS AND REQUIREMENTS Existing Site Hydrology There is currently one (1) single family residence on the property. The site grades generally from northeast to southwest. During heavy rainfall events, stormwater from the property sheet flows in a northerly direction toward 34th Avenue South. Developed Site Hydrology The project proposes to short plat the existing parcel into three (3) single family residential lots. Each of the new residential lots will consist of a total of approximately 2,400 sq ft of new impervious surface with the remainder of the new lots consisting of landscape and lawns. Design Requirements The 1998 King County Surface Water Manual sets forth the drainage requirements for this project. The proposed drainage facilities have been designed to meet or exceed the city standards using the design procedures set forth in the 1998 KCSWM. The drainage requirements are summarized in Table 1. Table 1 - Jurisdictional Requirements Peak Run -off Control: N/A — based on 0.1 cfs exemption Water Quality: N/A — based on square footage exemption Conveyance: 25- year developed flow Downstream Analysis: Level 1 SECTION 3: LEVEL 1 OFFSITE ANALYSIS Downstream Analysis A downstream analysis was conducted on July 14, 2008. The weather was sunny with temperatures in the high 70's degree Fahrenheit. During heavy rainfall events, stormwater from the property sheet flows in a northerly direction toward 341h Avenue South. Stormwater runoff is conveyed in a series of catch basins and underground pipes before discharging to the drainage system located along Military Road South. Stormwater is entirely contained in the public storm drainage system for the entire quarter mile analysis. There is no sign of erosion within a quarter mile of the project. Discharge at Natural (Existing) Location During heavy rainfall events, stormwater will continue to sheet flow toward 341h Avenue South. The Concept Group Page 2 Banakes Short Plat - Preliminary TIR January 2009 SECTION 4: FLOW CONTROL / WATER QUALITY ANALYSIS & DESIGN Flow Control This project will create approximately 9,295 square feet of new impervious surface. Flow control facilities are not required because the project creates less than 0.10 cfs increase in discharge from the existing condition for the 100 -year storm event per the KCRTS data below. Refer to Appendix D for flow control calculations. Infiltration Facility Design Onsite soils are not conducive to infiltrating stormwater from the roofs. No infiltration facility is proposed for the new residential structures. However, an infiltration trench is proposed for the access driveway stormwater. Drainage Analysis (KCRTS) The King County Runoff Time Series (KCRTS) Hydrologic Model is the required methodology under the 1998 King County Surface Water Design Manual for sizing detention facilities. The project is located in the Basic Flow Control Area. Tables 2 -4 summarize the KCRTS inputs. Table 2 - Existing Conditions Areas (acres) Till Forest Till Grass Impervious 0.00 0.527 0.030 Table 3 - Developed Conditions Areas (acres) Till Forest Till Grass Impervious 0.00 0.344 0.213 Table 4 - KCRTS Inputs Rainfall Region SeaTac Scale Factor 1.0 Tables 6 summarizes the KCRTS output. Table 5 - 100 Year Peak Runoff Rates (cfs) Existing Condition Developed Condition Difference in Discharge 0.125 0.173 0.048 Water Quality Although the project will create 9,295 square feet of new impervious surface, approximately 3,995 square feet is pollution - generating impervious surface (PGIS). PGIS is defined as "an impervious surface considered to be a significant source of pollutants in surface and storm water runoff. Such surfaces include those subject to The Concept Group Page 3 Banakes Short Plat - Preliminary TIR January 2009 vehicular use or storage of erodible or leachable materials, wastes, or chemicals, and which receive direct rainfall or the run -on or blow -in of rainfall." Non -metal rooftops are not considered PGIS; therefore, are not included in the PGIS area calculations. Water quality is not required for this project because the project does not create more than 5,000 sq ft of pollution generating impervious surfaces as defined in the KCSWM section 1.2.8. SECTION 5: CONVEYANCE SYSTEM No conveyance system will be constructed for this project. SECTION 6: SPECIAL REPORTS AND STUDIES There are no special reports or studies are expected to be prepared for this project. SECTION 7: OTHER PERMITS Permit for this project included: • Short Plat Approval • Building Construction Permit • Clearing & Grading Permit SECTION 8: CSWPP (EROSION CONTROL) ANALYSIS AND DESIGN All erosion and sediment control measures shall be governed by the requirements of the City of Tukwila. An Erosion and Sedimentation Control plan has been prepared to assist the contractor in complying with these requirements and designed to prevent sediment -laden run -off from leaving the site during construction. Refer to Appendix E for Erosion Control plans and details. The erosion potential of the site is influenced by four major factors: soil characteristics, vegetative cover, topography, and climate. Erosion/ sedimentation control is achieved by a combination of structural measures, cover measures, and construction practices that are tailored to fit the specific site. Construction Sequence and Procedure Prior to the start of any grading activity upon the site, all erosion control measures, including installation of a stabilized construction entrance, shall be installed in accordance with the construction documents. The best construction practice will be employed to properly clear and grade the site and to schedule construction activities. The planned construction sequence for the construction of the site is as follows: 1. Pre - construction meeting. 2. Post sign with name and phone number of ESC supervisor (may be consolidated with the required notice of construction sign). 3. Flag or fence clearing limits. The Concept Group Page 4 Banakes Short Plat - Preliminary TIR January 2009 4. Install catch basin protection if required. 5. Grade and install construction entrance(s). 6. Install perimeter protection (silt fence, brush barrier, etc.). 7. Construct sediment ponds and traps. 8. Grade and stabilize construction roads. 9. Construct surface water controls (interceptor dikes, pipe slope drains, etc.) simultaneously with clearing and grading for project development. 10.Maintain erosion control measures in accordance with King County standards and manufacturer's recommendations. 11. Relocate erosion control measures or install new measures so that as site conditions change the erosion and sediment control is always in accordance with the King County Erosion and Sediment Control Standards. 12.Cover all areas that will be unworked for more than seven days during the dry season or two days during the wet season with straw, wood fiber mulch, compost, plastic sheeting or equivalent. 13.Stabilize all areas that reach final grade within seven days. 14. Seed or sod any areas to remain unworked for more than 30 days. 15.Upon completion of the project, all disturbed areas must be stabilized and BMPs removed if appropriate. Trapping Sediment Structural control measures will be used to reduce erosion and retain sediment on the construction site. The control measures will be selected to fit specific site and seasonal conditions. The following structural items will be used to control erosion and sedimentation processes: • Temporary gravel construction entrance • Filter fabric fences (Silt fences) • Ground cover measures such as straw cover and /or hydroseeding • Inlet protection Vehicle tracking of mud off -site shall be avoided. Installation of a gravel construction entrance will be installed at a location to enter the site. The entrances are a minimum requirement and may be supplemented if tracking of mud onto public streets becomes excessive. SECTION 9: BOND QUANTITIES AND DECLARATIONS OF COVENANTS None known at the time this report was prepared. SECTION 10: OPERATIONS AND MAINTENANCE The owner or operator of the project shall be responsible for maintaining the stormwater facilities in accordance with the requirements as attached in Appendix F. Proper maintenance is important for adequate functioning of the stormwater facilities. If it is unclear whether a problem exists, contact a Professional Engineer.

After samples were sufficiently dry, the samples were passed through a series of sieves and the fraction remaining on each sieve was weighed. The fraction of the sample that was left in the pan after sieving represents fine silt and clays. To further break down this fraction requires hydrometer analysis at an extra cost. General classification of soil types were as follows: Classification Particle diameter Coarse Gravel >19.0mm Medium Gravel >9.5mm Fine Gravel >4.75mm Very Fine Gravel >2.0mm Very Coarse Sand >850pm Coarse Sand >425pm Medium Sand >250pm Fine Sand >106pm Very Fine Sand >75pm Silt >63pm Clay <63pm 1.2.

A perforated pipe connection is a length of drainage conveyance pipe with holes in the bottom, designed to "leak" runoff, conveyed by the pipe, into a gravel filled trench where it can be soaked into the surrounding soil. The connection is intended to provide opportunity for infiltration of any runoff that is being conveyed from an impervious surface (usually a roof) to a local drainage system such as a ditch or roadway pipe system. The size and composition of the perforated pipe connection as depicted by the flow control BMP site plan and design details must be maintained and may not be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. The soil overtop of the perforated portion of the system must not be compacted or covered with impervious materials.

For projects in Small Project Drainage Review, these measures may be used if no more than 3 acres of soil will be disturbed by the project. Other ESC measures may be allowed or required by DDES if these are inappropriate for the project or fail to contain sediment on the project site. A description of other measures and a more detailed description of those included here can be found in the ESC Standards. Projects that disturb 3 acres or more of soil will require an ESC plan developed by a civil engineer under a Targeted Drainage Review. Intent of ESC Measures The intent of ESC measures is to prevent, to the maximum extent practicable, the transport of sediment and other construction- related pollutants to streams, wetlands, lakes, drainage systems, and adjacent properties during and after construction. Erosion of disturbed areas on construction sites can result in excessive sediment transport to adjacent properties and to surface waters. This sediment can result in major adverse impacts, such as flooding due to obstructed drainage ways, smothering of salmonid spawning beds, creation of algal blooms in lakes, and violation of State water quality standards for turbidity. In addition to sediment, other construction- related pollutants can be generated by uncovered waste materials, stockpiles, and demolition debris; de- watering; maintenance and operation of heavy equipment; chemical spills; oil spills; placement of concrete; and application of fertilizers and pesticides. Such pollutants can be toxic to both fish and humans and may violate State water quality standards and the prohibited discharges section of KCC 9.12. Stabilization of the site after construction and prior to the wet season is also important to preventing these impacts. Organization of Section C.3 The ESC measures in this section are divided into two categories, those used during construction and those used after. Those measures used during construction are referred to as temporary ESC measures while those used after construction are referred to as permanent or final stabilization measures. Thus, the section is organized as follows: • Section C.3.1, "Temporary ESC" (p. C -79) • Section C.3.2, "Final Stabilization" (p. C -90) C.3.1 TEMPORARY ESC Temporary ESC measures are used during construction to minimize the amount of sediment mobilized and trap any mobilized sediment before it leaves the project site. This section presents the requirements and specifications for those temporary ESC measures typically applied to projects in Small Project Drainage Review. They include the following: • "Stabilized Construction Entrance," Section C.3.1.1 (p. C -80) • "Mulching," Section C.3.1.2 (p. C -81) • "Nets and Blankets," Section C.3.1.3 (p. C -83) • "Plastic Covering," Section C.3.1.4 (p. C -85) • "Mark Clearing Limits/Minimize Clearing," Section C.3.1.5 (p. C -86) • "Silt Fence," Section C.3.1.6 (p. C -86) • "Vegetated Strip," Section C.3.1.7 (p. C -88) 2005 Surface Water Design Manual — Appendix C 1/24/2005 C -79 SECTION C.3 EROSION AND SEDIMENT CONTROL (ESC) MEASURES • "Triangular Silt Dike," Section C.3.1.8 (p. C -89) • "Winter Stabilization," Section C.3.1.9 (p. C -90) The above measures must be implemented as needed to prevent the discharge of sediment -laden water from the construction site. Proposed measures must be shown on the small site ESC plan required to be submitted with the small project drainage plans. Site - specific conditions during construction may require additional measures as deemed necessary by DDES. As noted in Section C.3 above, other temporary ESC measures found in Appendix D of the SWDM may be needed or may be more appropriate for the project site as determined by DDES. C.3.1.1 STABILIZED CONSTRUCTION ENTRANCE Purpose Construction entrances are stabilized to reduce the amount of sediment transported onto paved roads by motor vehicles or runoff by constructing a stabilized pad of quarry spalls at the entrances to construction sites. Application Construction entrances shall be stabilized wherever traffic will be leaving a construction site and traveling on paved roads or other paved areas within 1,000 feet of the site. Design and Installation Specifications 1. See Figure C.3.1.A for details. 2. A separation geotextile shall be placed under the spalls to prevent fine sediment from pumping up into the rock pad. The geotextile shall meet the following standards: Grab Tensile Strength (ASTM D4751) 200 psi min. Grab Tensile Elongation (ASTM D4632) 30% max. Mullen Burst Strength (ASTM D3786 -80a) 400 psi min. AOS (ASTM D4751) 20 -45 (U.S. standard sieve size) 3. Hog fuel (wood based mulch) may be substituted for or combined with quarry spalls in areas that will not be used for permanent roads. The effectiveness of hog fuel is highly variable, but it has been used successfully on many construction sites. It generally requires more maintenance than quarry spalls. Hog fuel is not recommended for entrance stabilization in urban areas. The inspector may at any time require the use of quarry spalls if the hog fuel is not preventing sediment from being tracked onto pavement or if the hog fuel is being carried onto pavement. Hog fuel is prohibited in permanent roadbeds because organics in the subgrade soils cause difficulties with compaction. 4. Whenever possible, the entrance shall be constructed on a firm, compacted subgrade. This can substantially increase the effectiveness of the pad and reduce the need for maintenance. Maintenance 1. Quarry spalls (or hog fuel) shall be added if the pad is no longer in accordance with the specifications. 2. If the entrance is not preventing sediment from being tracked onto pavement, then alternative measures to keep the streets free of sediment shall be used. This may include street sweeping, an increase in the dimensions of the entrance, or the installation of a wheel wash. If washing is used, it 1/24/2005 2005 Surface Water Design Manual — Appendix C C -80 C.3.1 TEMPORARY ESC shall be done on an area covered with crushed rock, and wash water shall drain to a sediment trap or pond. 3. Any sediment that is tracked onto pavement shall be removed immediately by sweeping. The sediment collected by sweeping shall be removed or stabilized onsite. The pavement shall not be cleaned by washing down the street, except when sweeping is ineffective and there is a threat to public safety. If it is necessary to wash the streets, a small sump must be constructed. The sediment would then be washed into the sump where it can be controlled and discharged appropriately. 4. Any quarry spalls that are loosened from the pad and end up on the roadway shall be removed immediately. FIGURE C.3.1.A STABILIZED CONSTRUCTION ENTRANCE RO p0 Ex�s�\NG R = 25' MIN.

THICKNESS - -. C.3.1.2 MULCHING . PROVIDE FULL WIDTH OF INGRESS /EGRESS AREA Purpose The purpose of mulching soils is to provide immediate temporary protection from erosion. Mulch also enhances plant establishment by conserving moisture, holding fertilizer, seed, and topsoil in place, and moderating soil temperatures. There is an enormous variety of mulches that may be used. Only the most common types are discussed in this section. Conditions of Use As a temporary cover measure, mulch should be used: 1. On disturbed areas that require cover measures for less than 30 days 2. As a cover for seed during the wet season and during the hot summer months 3. During the wet season on slopes steeper than 3H: 1 V with more than 10 feet of vertical relief. 2005 Surface Water Design Manual — Appendix C 1/24/2005 C -81 SECTION C.3 EROSION AND SEDIMENT CONTROL (ESC) MEASURES Design and Installation Specifications For mulch materials, application rates, and specifications, see Table C.3.1.A. Note: Thicknesses may be increased for disturbed areas in or near critical areas or other areas highly susceptible to erosion. Maintenance Standards 1. The thickness of the mulch cover must be maintained. 2. Any areas that experience erosion shall be re- mulched and/or protected with a net or blanket. If the erosion problem is drainage related, then the drainage problem shall be assessed and alternate drainage such as interceptor swales may be needed to fix the problem and the eroded area re- mulched. 1/24/2005 C -82 2005 Surface Water Design Manual — Appendix C TABLE C 31 MULCH STANDARDS AND GUIDELINES 3 , i 9 si �i , ha x Mulch Material Quality Standards Application Rates Remarks Straw Air - dried; free from undesirable seed and coarse material 2 " -3" thick; 2 -3 bales per 1000 sf or 2 -3 tons per acre Cost - effective protection when applied with adequate thickness. Hand - application generally requires greater thickness than blown straw. Straw should be crimped to avoid wind blow. The thickness of straw may be reduced by half when used in conjunction with seeding. Wood Fiber Cellulose No growth inhibiting factors Approx. 25 -30 lbs per 1000 sf or 1000 -1500 lbs per acre Shall be applied with hydromulcher. Shall not be used without seed and tackifier unless the application rate is at least doubled. Some wood fiber with very long fibers can be effective at lower application rates and without seed or tackifier. Compost No visible water or dust during handling. Must be purchased from supplier with Solid Waste Handling Permit. 2" thick min.; approx. 100 tons per acre (approx. 800 lbs per cubic yard) More effective control can be obtained by increasing thickness to 3 ". Excellent mulch for protecting final grades until landscaping because it can be directly seeded or tilled into soil as an amendment. Sources for compost are available from the King County Commission for Marketing Recyclable Materials at (206) 296 -4439. Hydraulic Matrices (Bonded Fiber Matrix) This mulch category includes hydraulic slurries composed of wood fiber, paper fiber or a combination of the two held together by a binding system. The BFM shall be a mixture of long wood fibers and various bonding agents. Apply at rates from 3,000 lbs per acre to 4,000 lbs per acre and based on manufacturers recommendations The BFM shall not be applied immediately before, during or immediately after rainfall so that the matrix will have an opportunity to dry for 24 hours after installation. Application rates beyond 2,500 pounds may interfere with germination and are not usually recommended for turf establishment. BFM is generally a matrix where all fiber and binders are in one bag, rather than having to mix components from various manufacturers to create a matrix. BFMs can be installed via helicopter in remote areas. They are approximately $1,000 per acre cheaper to install. Chipped Site Vegetation Average size shall be several inches. 2" minimum thickness This is a cost - effective way to dispose of debris from clearing and grubbing, and it eliminates the problems associated with burning. Generally, it should not be used on slopes above approx. 10% because of its tendency to be transported by runoff. It is not recommended within 200 feet of surface waters. If seeding is expected shortly after mulch, the decomposition of the chipped vegetation may tie up nutrients important to grass establishment. 1/24/2005 C -82 2005 Surface Water Design Manual — Appendix C C.3.1 TEMPORARY ESC C.3.1.3 NETS AND BLANKETS Purpose Erosion control nets and blankets are intended to prevent erosion and hold seed and mulch in place on steep slopes and in channels so that vegetation can become well established. In addition, some nets and blankets can be used to permanently reinforce turf to protect drainage ways during high flows. Nets are strands of material woven into an open, but high - tensile strength net (for example, jute matting). Blankets are strands of material that are not tightly woven, but instead form a layer of interlocking fibers, typically held together by a biodegradable or photodegradable netting (for example, excelsior or straw blankets). They generally have lower tensile strength than nets, but cover the ground more completely. Coir (coconut fiber) fabric comes as both nets and blankets. Conditions of Use Erosion control nets and blankets should be used: 1. For permanent stabilization of slopes 2H:1 V or greater and with more than 10 feet of vertical relief. 2. In conjunction with seed for final stabilization of a slope, not for temporary cover. However, they may be used for temporary applications as long as the product is not damaged by repeated handling. In fact, this method of slope protection is superior to plastic sheeting, which generates high - velocity runoff. 3. For drainage ditches and swales (highly recommended). The application of appropriate netting or blanket to drainage ditches and swales can protect bare soil from channelized runoff while vegetation is established. Nets and blankets also can capture a great deal of sediment due to their open, porous structure. Synthetic nets and blankets may be used to permanently stabilize channels and may provide a cost - effective, environmentally preferable alternative to riprap. Design and Installation Specifications 1. See Figure C.3.1.B and Figure C.3.1.0 for typical orientation and installation of nettings and blankets. Note: Installation is critical to the effectiveness of these products. If good ground contact is not achieved, runoff can concentrate under the product, resulting in significant erosion. 2. Jute matting must be used in conjunction with mulch. Excelsior, woven straw blankets, and coir (coconut fiber) blankets may be installed without mulch. There are many other types of erosion control nets and blankets on the market that may be appropriate in certain circumstances. Other types of products will have to be evaluated individually. In general, most nets (e.g., jute matting) require mulch in order to prevent erosion because they have a fairly open structure. Blankets typically do not require mulch because they usually provide complete protection of the surface. 3. Purely synthetic blankets are allowed but shall only be used for long -term stabilization of waterways. The organic blankets authorized above are better for slope protection and short-term waterway protection because they retain moisture and provide organic matter to the soil, substantially improving the speed and success of re- vegetation. Maintenance Standards 1. Good contact with the ground must be maintained, and there must not be erosion beneath the net or blanket. 2. Any areas of the net or blanket that are damaged or not in close contact with the ground shall be repaired and stapled. 3. If erosion occurs due to poorly controlled drainage, the problem shall be fixed and the eroded area protected. 2005 Surface Water Design Manual — Appendix C 1/24/2005 C -83 SECTION C.3 EROSION AND SEDIMENT CONTROL (ESC) MEASURES FIGURE C.3.1.B WATERWAY INSTALLATION DO NOT STRETCH BLANKETSIMATTINGS TIGHT - ALLOW THE ROLLS TO MOLD TO ANY IRREGULARITIES SLOPE SURFACE SHALL BE SMOOTH BEFORE PLACEMENT FOR PROPER SOIL CONTACT ANCHOR, STAPLE, AND INSTALL CHECK SLOTS AS PER MANUFACTURER'S RECOMMENDATIONS AVOID JOINING MATERIAL IN THE CENTER OF THE DITCH LIME, FERTILIZE AND SEED BEFORE INSTALLATION MIN. 4" OVERLAP 111-41 111 -1. - III =III= 111��1 =1 11 =1 11 =1 I I -1 11 1 11= � � I_iTi 1 � 111 =' MIN. 6' OVERLAP FIGURE C.3.1.0 SLOPE INSTALLATION SLOPE SURFACE SHALL BE SMOOTH BEFORE PLACEMENT FOR PROPER SOIL CONTACT STAPLING PATTERN AS PER MANUFACTURER'S RECOMMENDATIONS MIN. 2" OVERLAP IF THERE IS A BERM AT THE TOP OF SLOPE, ANCHOR UPSLOPE OF THE BERM ANCHOR IN 6 "x6" MIN.

Conditions of Use 1. Plastic covering may be used on disturbed areas that require cover measures for less than 30 days. 2. Plastic is particularly useful for protecting cut and fill slopes and stockpiles. Note: The relatively rapid breakdown of most polyethylene sheeting makes it unsuitable for long -term applications. 3. Clear plastic sheeting may be used over newly - seeded areas to create a greenhouse effect and encourage grass growth. Clear plastic should not be used for this purpose during the summer months because the resulting high temperatures can kill the grass. 4. Due to rapid runoff caused by plastic sheeting, this method shall not be used upslope of areas that might be adversely impacted by concentrated runoff. Such areas include steep and/or unstable slopes. Note: There have been many problems with plastic, usually attributable to poor installation and maintenance. However, the material itself can cause problems, even when correctly installed and maintained, because it generates high - velocity runoff and breaks down quickly due to ultraviolet radiation. In addition, if the plastic is not completely removed, it can clog drainage system inlets and outlets. It is highly recommended that alternatives to plastic sheeting be used whenever possible and that its use be limited. Design and Installation Specifications 1. See Figure C.3.1.D for details. 2. Plastic sheeting shall have a minimum thickness of 0.06 millimeters. 3. If erosion at the toe of a slope is likely, a gravel berm, riprap, or other suitable protection shall be installed at the toe of the slope in order to reduce the velocity of runoff. FIGURE C.3.1.D PLASTIC COVERING f10' MAX.

PROVIDE ENERGY DISSIPATION AT TOE WHEN NEEDED 2005 Surface Water Design Manual — Appendix C C -85 1/24/2005 SECTION C.3 EROSION AND SEDIMENT CONTROL (ESC) MEASURES Maintenance Standards for Plastic Covering 1. Torn sheets must be replaced and open seams repaired. 2. If the plastic begins to deteriorate due to ultraviolet radiation, it must be completely removed and replaced. C.3.1.5 MARK CLEARING LIMITS/MINIMIZE CLEARING Purpose Minimizing clearing is the most effective method of erosion control. Undisturbed vegetation intercepts and slows rainwater. Plant roots hold soil in place, and dead vegetation on the ground acts as a mulch. Applications Clearing limits shall be marked and clearing minimized on any site where significant areas of undisturbed vegetation will be retained. Design Specifications Minimizing clearing should be incorporated into the site design. Clearing limits must be marked on the small site ESC plan. On the ground, clearing limits must be clearly marked with brightly colored tape or plastic or metal safety fencing. If tape is used, it should be supported by vegetation or stakes, and should be about 3 to 6 feet high and highly visible. Equipment operators should be informed of areas of vegetation that are to be left undisturbed. Maintenance Fencing shall be inspected regularly and repaired or replaced as needed. C.3.1.6 SILT FENCE Purpose Use of a silt fence reduces the transport of coarse sediment from a construction site by providing a temporary physical barrier to sediment and reducing the runoff velocities of overland flow. Conditions of Use Silt fence may be used downslope of all disturbed areas. Silt fence is not intended to treat concentrated flows, nor is it intended to treat substantial amounts of overland flow. Design and Installation Specifications 1. See Figure C.3.1.E and Figure C.3.1 .F for details. 2. The geotextile used must meet the standards listed below. A copy of the manufacturer's fabric specifications must be available onsite. AOS (ASTM D4751) 30 -100 sieve size (0.60 -0.15 mm) for slit film 50 -100 sieve size (0.30 -0.15 mm) for other fabrics Water Permittivity (ASTM D4491) 0.02 sec-1 minimum Grab Tensile Strength (ASTM D4632) 180 lbs. min. for extra strength fabric 100 lbs. min. for standard strength fabric Grab Tensile Elongation (ASTM D4632) 30% max. Ultraviolet Resistance (ASTM D4355) 70% min. 1/24/2005 2005 Surface Water Design Manual — Appendix C C -86 C.3.1 TEMPORARY ESC 3. Standard strength fabric requires wire backing to increase the strength of the fence. Wire backing or closer post spacing may be required for extra strength fabric if field performance warrants a stronger fence. 4. Where the fence is installed, the slope shall be no steeper than 2H:1 V. 5. If a typical silt fence (per Figure C.3.1.E) is used, the standard 4 x 4 trench may not be reduced as long as the bottom 8 inches of the silt fence is well buried and secured in a trench that stabilizes the fence and does not allow water to bypass or undermine the silt fence. Maintenance Standards 1. Any damage shall be repaired immediately. 2. If concentrated flows are evident uphill of the fence, they must be intercepted and conveyed to a sediment trap or pond. 3. It is important to check the uphill side of the fence for signs of the fence clogging and acting as a barrier to flow and then causing channelization of flows parallel to the fence. If this occurs, replace the fence or remove the trapped sediment. 4. Sediment must be removed when the sediment is 6 inches high. 5. If the filter fabric (geotextile) has deteriorated due to ultraviolet breakdown, it shall be replaced. FIGURE C.3.1.E SILT FENCE JOINTS IN FILTER FABRIC SHALL BE SPLICED AT POSTS.

Conditions of Use Vegetated strips may be used downslope of all disturbed areas. Vegetated strips are not intended to treat concentrated flows, nor are they intended to treat substantial amounts of overland flow. Design and Installation Specifications 1 The vegetated strip shall consist of a 25 -foot minimum width continuous strip of dense vegetation with a permeable topsoil. Grass - covered, landscaped areas are generally not adequate because the volume of sediment overwhelms the grass. Ideally, vegetated strips shall consist of undisturbed native growth with a well - developed soil that allows for infiltration of runoff. 2. The slope within the strip shall not exceed 4H:1 V. 3. The uphill boundary of the vegetated strip shall be delineated with clearing limits as specified in Section C.3.1.5 (p. C -86). 1/24/2005 2005 Surface Water Design Manual — Appendix C C -88 C.3.I TEMPORARY ESC Maintenance Standards 1. Any areas damaged by erosion or construction activity shall be seeded immediately and protected by mulch. 2. If more than 5 feet of the original vegetated strip width has had vegetation removed or is being eroded, sod must be installed. C.3.1.8 TRIANGULAR SILT DIKE Purpose Triangular silt dikes (TSDs) may be used as check dams, for perimeter protection, for temporary soil stockpile protection, for drop inlet protection, or as a temporary interceptor dike. Silt dikes, if attached to impervious surfaces with tack or other adhesive agent may also be used as temporary wheel wash areas, or concrete washout collection areas. Conditions of Use 1. May be used for temporary check dams in ditches. 2. May be used on soil or pavement with adhesive or staples. 3. TSDs have been used to build temporary sediment ponds, diversion ditches, concrete washout facilities, curbing, water bars, level spreaders, and berms. Design and Installation Specifications 1. TSDs must be made of urethane foam sewn into a woven geosynthetic fabric. 2. TSDs are triangular, 10 inches to 14 inches high in the center, with a 20 -inch to 28 -inch base. A 2- foot apron extends beyond both sides of the triangle along its standard section of 7 feet. A sleeve at one end allows attachment of additional sections as needed 3. Install TSDs with ends curved up to prevent water from flowing around the ends 4. Attach the TSDs and their fabric flaps to the ground with wire staples. Wire staples must be No. 11 gauge wire or stronger and shall be 200 mm to 300 mm in length. 5. When multiple units are installed, the sleeve of fabric at the end of the unit shall overlap the abutting unit and be stapled. 6. TSDs must be located and installed as soon as construction will allow. 7. TSDs must be placed perpendicular to the flow of water. 8. When used as check dams, the leading edge must be secured with rocks, sandbags, or a small key slot and staples. 9. When used in grass -lined ditches and swales, the TSD check dams and accumulated sediment shall be removed when the grass has matured sufficiently to protect the ditch or swale unless the slope of the swale is greater than 4 percent. The area beneath the TSD check dams shall be seeded and mulched immediately after dam removal. Maintenance Standards 1. Triangular silt dikes shall be monitored for performance and sediment accumulation during and after each runoff producing rainfall event. Sediment shall be removed when it reaches one half the height of the silt dike. 2. Anticipate submergence and deposition above the triangular silt dike and erosion from high flows around the edges of the dike /dam. Immediately repair any damage or any undercutting of the dike /dam. 2005 Surface Water Design Manual — Appendix C 1/24/2005 C -89 SECTION C.3 EROSION AND SEDIMENT CONTROL (ESC) MEASURES C.3.1.9 WINTER STABILIZATION Purpose In order to minimize sediment -laden runoff, as much of the bare and disturbed portions of the project site as possible should be covered during any period of precipitation. Once sediment is mobilized, it is much more difficult to effectively control. Application All project sites require winter stabilization between October 1 and April 30 (the wet season). Design Specifications During the above time frame, slopes and stockpiles 3H:1 V or steeper and with more than 10 feet of vertical rise shall be covered if they are to remain unworked for more than 12 hours. Other disturbed areas shall be covered or mulched according to Table C.3.1.A (p. C -82) if they are to remain unworked for more than two days. Cover material sufficient to cover all disturbed areas shall be stockpiled on the site at the beginning of the wet season. Areas that are to be left unworked during the winter shall be seeded prior to September 23. Maintenance The project site should be inspected weekly and immediately before, during, and after storms. Cover and other erosion control measures shall be repaired and enhanced as necessary to prevent or minimize sediment runoff and transport. C.3.2 FINAL STABILIZATION Purpose Final stabilization minimizes sediment -laden runoff from the project site after construction has been completed. Application All sites require final stabilization prior to final construction approval. Design Specifications Prior to final construction approval, the project site shall be stabilized to prevent sediment -laden water from leaving the project site after project completion. All disturbed areas of the project site shall be vegetated or otherwise permanently stabilized. At a minimum, disturbed areas must be seeded and mulched to ensure that sufficient cover will develop shortly after final approval. Mulch without seeding is adequate for small areas to be landscaped before October 1. All permanent surface water facilities (including catch basins, manholes, pipes, ditches, channels, flow control facilities, and water quality facilities) impacted by sedimentation during construction must be cleaned. Maintenance Permanent erosion control is the responsibility of the owner. The project site must be kept stabilized using landscaping, mulch, or other measures to prevent sediment -laden water from leaving the project site and to prevent sediment from being transported onto adjacent properties and roads. 1/24/2005 2005 Surface Water Design Manual — Appendix C C -90 Banakes Short Plat - Preliminary TIR January 2009 Appendix F Maintenance Procedures The Concept Group Appendices APPENDIX A MAINTENANCE STANDARDS FOR PRIVATELY MAINTAINED DRAINAGE FACILITIES NO.2 - INFILTRATION Maintenance Component General Storage Area Defect Conditions When Maintenance Is Needed Results Expected When Maintenance Is Performed Filter Bags Rock Filters Side Slopes of Pond Emergency Overflow Spillway Settling Ponds and Vaults Trash & Debris Poisonous Vegetation Pollution Unmowed Grass/ Ground Cover Rodent Holes Insects Sediment Sheet Cover (If Applicable) Sump Filled with Sediment and Debris (If Applicable) Filled with Sediment and Debris Sediment and Debris Erosion Rock Missing Sediment See "Ponds" Standard No. 1 See 'Ponds" Standard No. 1 See "Ponds" Standard No. 1 See "Ponds" Standard No. 1 See "Ponds" Standard No. 1 See "Ponds" Standard No. 1 A percolation test pit or test of facility indicates facility is only working at 90% of its designed capabilities.

They are required for any pipe connection of roof downspouts to the local drainage system regardless of the extent to which flow control BMPs are required or being used onsite. Perforated pipe connections are intended to provide for some infiltration during drier periods (late spring through early fall), which may help dampen the flashiness of stream flows in developed areas and provide some groundwater recharge. During the wet winter months, however, this BMP likely provides little or no flow control benefits. Therefore, it is not credited with mitigating target impervious surface. Applicable Surfaces Subject to the minimum design requirements below, the perforated pipe connection may be applied to concentrated runoff from any impervious surface or non - native pervious surface. Operation and Maintenance See Section C.2.11.2 (below). C.2.11.1 MINIMUM DESIGN REQUIREMENTS Figure C.2.11.A (p. C -78) illustrates a perforated pipe connection for a typical single family residence. Impervious areas larger than 10,000 square feet and non -native pervious areas larger than 35,000 square feet may require larger pipe to adequately convey flows and should be designed by a civil engineer. Perforated pipe connections must be installed according to the following requirements: 1. Where possible, the perforated pipe connection must be placed in native soil to maximize infiltration of water, and must not be located under impervious surfaces, except as a last resort. 2. The gravel filled trench must be at least 10 -feet in length for every 10,000 square feet of impervious surface or 35,000 square feet of non- native pervious surface from which runoff is conveyed. 3. The perforated portion of the system may not be placed in a critical area buffer or on slopes steeper than 25 %. Any proposed placement of the perforated portion on slopes steeper than 15% or within 50 feet of a steep slope hazard area or landslide hazard area must be approved by a geotechnical engineer or engineering geologist unless otherwise approved by the DDES staff geologist. 4. For sites with septic systems, the perforated portion of the system must be down slope of the drainfield primary and reserve areas. DDES permit review staff can waive this requirement if site topography clearly prohibits subsurface flows from intersecting the drainfield. 5. The perforated pipe connection must not create flooding or erosion impacts as determined by DDES. If the system discharges toward or is near a landslide hazard area, erosion hazard area, steep slope hazard area, or a slope steeper than 15 %, DDES may require evaluation and approval of the proposal by a geotechnical engineer or engineering geologist. C.2.11.2 MAINTENANCE INSTRUCTIONS If the perforated pipe connection flow control BMP is required for a project, the following maintenance and operation instructions must be recorded as an attachment to the required declaration of covenant and grant of easement per Requirement 3 of Section C.1.3.3 (p. C -18). The intent of these instructions is to explain to future property owners, the purpose of the BMP and how it must be maintained and operated. These instructions are intended to be a minimum; DDES may require additional instructions based on site - specific conditions. Also, as the County gains more experience with the maintenance and operation of these BMPs, future updates to the instructions will be posted on King County's Surface Water Design Manual website. 2005 Surface Water Design Manual — Appendix C C -77 1/24/2005 • • SAAPLE After recording, please return to: Sandra J.

The checklist includes a series of "Yes" or "No" questions about your project, organized into four parts. Starting with Part A on Page 1, read each question carefully, circle "Yes" or "No," and proceed to the next question as directed by the checklist. To answer these questions, you may need to refer to site plans, grading and drainage plans, critical areas studies, or other documents you have prepared for your project. The City will evaluate your responses to determine if "take" is indicated. Part A: Please review and answer each question carefully. Consider all phases of your project including, but not limited to, construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 1 -0 Will the project require any form of grading? Grading is defined as any excavating, filling, clearing, or creation of impervious surface, or any combination thereof, which alters the existing ground surface of the earth (TMC 18.06.370). Please circle appropriate response. NO - Continue to Question 2 -0 Continue to Question 1 -1 (Page 3) 2 -0 Will the project require any form of clearing? Clearing means the removal or causing to be removed, through either direct or indirect actions, any vegetation from a site (18.06.145). Please circle appropriate response. NO - Continue to Question 3 -0 COontinue to Question 2 -1 (Page 4) 3 -0 Will the project require work, during any time of the project, below the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers or in wetlands? Ordinary high water mark is the mark that is found by examining the bed and banks of a stream and ascertaining where the presence and action of waters are so common and usual as to distinctly mark the soil from that of the abutting upland, in respect to vegetation (see TMC Chapter 18.06, ' ..e 18 -15). Please circle appropriate response. NO - ontinue to Question 4 -0 YES - Continue to Question 3 -1 (Page 5) 4-0 Will the project result in the processing or handling, storage, or treatment of hazardous substances? This does not include the proper use of fuel stored in a vehicle's fuel tank. Hazardous substances are any liquid, solid, gas, or sludge, including any material, substance, product, commodity, or waste, regardless of quantity, that exhibits the characteristics or criteria of hazardous waste as defined by Washington Administrative Code 173 -303 (TMC 18.06.385). This includes fuel or other chemicals stored on -site during construction.

Checklist Complete — Checklist Complete Part B: Please answer each question below for projects that include grading. Review each question carefully, considering all phases of your project including, but not limited to construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 1 -1 Will the project involve the modification of a watercourse bank or bank of the Green/Duwamish or Black Rivers between the ordinary high water mark and top of bank? This includes any projects that will require grading on any slope leading to a river or stream, but will not require work below the ordinary high water mark. Work below the ordinary high water mark is covered in Part C. Please circle appropriate response. Continue to Question 1 -2 YES - Continue to Question 1 -2 1 -2 Could the construction, operation, or maintenance of the project result in sediment transport off site or increased rates of erosion and/or sedimentation in watercourses, the Green/Duwamish rivers, or the Black River? Most projects that involve grading have the potential to result in increased erosion and/or sedimentation as a result of disturbances to the soil or earth. If your project involves grading and you have not prepared a Temporary Erosion and Sedimentation Control Plan specifically designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please circle appropriate response. Continue to Question 1 -3 YES - Continue to Question 1 -3 1 -3 Will the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development. Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development (TMC 18.06.445). Please circle appropriate response. N Continue to Question 2 -0 (Page 2) Continue to Question 1 -4 City of TukwilISA Screening Checklist Part B (continued) 1 -4 Will your project generate stormwater from the creation of impervious surfaces that will not be infiltrated on site?

Review each question carefully, considering all phases of your project including, but not limited to, construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 3 -1 Will the project involve the direct alteration of the channel or bed of a watercourse, the Green/Duwamish rivers, or Black River? For the purpose of this analysis, channel means the area between the ordinary high water mark of both banks of a stream, and bed means the stream bottom substrates, typically within the normal wetted -width of a stream. This includes both temporary and permanent modifications. Please circle appropriate response. NO - Continue to Question 3 -2 YES - Continue to Question 3 -2 3 -2 Will the project involve any physical alteration to a watercourse or wetland connected to the Green/Duwamish River? For the purpose of this analysis, "connected to the river means" flowing into via a surface connection or culvert, or having other physical characteristics that allow for access by salmonids. This includes impacts to areas such as sloughs, side channels, remnant oxbows, ditches formed from channelized portions of natural watercourses or any area that may provide off channel rearing habitat for juvenile fish from the Duwamish River. This includes both temporary construction alterations and permanent modifications. Watercourses or wetlands draining to the Green/Duwamish River that have a hanging culvert, culvert with a flap gate, diversion, or any entirely man-made or artificial structure that precludes fish access should answer Yes to this question. Please circle appropriate response. NO - Continue to Question 3 -3 YES - Continue to Question 3 -3 3 -3 Will the project result in the construction of a new structure or hydraulic condition that could be a barrier to salmonid passage within the watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis, a barrier means any artificial or human modified structure or hydraulic condition that inhibits the natural upstream or downstream movement of salmonids, including both juveniles and adults. Please circle appropriate response. NO - Continue to Question 3 -4 YES - Continue to Question 3 -4 3 -4 Will the project involve a temporary or permanent change in the cross - sectional area of a watercourse or the Green/Duwamish or Black Rivers?
