FINDINGS OF FACT AND CONCLUSIONS A. Setting 244th Street SW is a minor arterial connecting the Firdale Village and Westgate areas to Highway 99, and 1-5 further to the east (Attachment 3). The project site was rezoned in 2012 to Multifamily Residential (RM-2.4). To the east are properties zoned Multifamily Residential (RM-1.5) and General Commercial (CG). To the north and west are single family neighborhoods. South of 244th Street is the City of Shoreline. B. Environmental Assessment 1. Critical Area: The subject property was reviewed and inspected for critical areas under file CRA20170034. It was determined that the site does not contain any critical areas and so a waiver from further critical area study was granted. 2. Shoreline: The subject property is not located within shoreline jurisdiction. 3. SEPA: Review under the State Environmental Policy Act (SEPA) was completed with the design review for the project under permit PLN20170017. A determination of nonsignificance was issued on April 28, 2017 and was not 244th Street Preliminary Unit Lot Plat File No. PLN20170047 Page 2 of 13 Packet Pg. 4 2.1.a appealed. The existing checklist and determination are adopted as part of this unit lot subdivision because that determination addressed the environmental impacts of the project and no additional environmental impacts are anticipated from the unit lot plat (Attachment 8). C. Comments 1. Technical Comments In addition to the Planning Division, this project was reviewed by the Building and Engineering Divisions as well as South Snohomish County Fire & Rescue. Fire noted several dimensional requirements and the requirement for a fire hydrant at the entrance to the complex. Building indicated requirements for demolition permits (which have already been issued and acted upon) and park impact fees (Attachments 11 & 12). The Engineering Division had a number of comments and corrections on the initial submittal (Attachment 13) and additional comments on the first resubmittal (Attachment 19). The second resubmittal on August 20, 2018 (Attachment 20) resolved the issues and so Engineering noted the revised preliminary unit lot plat shows general engineering feasibility (Attachment 21), These groups are also reviewing the associated building permits and will verify compliance with their codes as part of those reviews. 2. Public Notice and Comme This application was submitted on September 28, 2017 (Attachment 1) and determined to be incomplete on October 26, 2017 (Attachment 14). The applicant requested a 90-day application extension on January 17, 2018 (which was granted - Attachment 15) and responded to the incomplete notice on April 20, 2018 (Attachment 16). The application was determined to be complete on May 3, 2018 (Attachment 17). Pursuant to ECDC 20.03, a "Notice of Application" was posted at the subject site, Public Safety Complex, Development Services Department, and Library on May 17, 2018. The notice was also published in the Herald Newspaper and mailed to property owners within 300 feet of the site using a mailing list provided by the applicant (Attachment 18). A "Notice of Public Hearing" was published in the Everett Herald, posted at the subject site, Public Safety Complex, Development Services Department, and Library on September 25, 2018. The notice was also mailed to property owners within 300 feet of the site using the mailing list provided by the applicant (Attachment 22). Notice of the application and hearing were also provided to the City of Shoreline and Snohomish County because those jurisdictions are within one mile of the unit lot subdivision project. 244th Street Preliminary Unit Lot Plat File No. PLN20170047 Page 3 of 13 Packet Pg. 5 2.1.a To date, no public comments have been received. D. ECDC 20.75.045 Unit Lot Subdivision Staff's findings regarding ECDC 20.75.045 are described below. 1. Purpose. The unit lot subdivision process provides opportunities for dividing fee simple ownership of land to create townhouses, rowhouses and similar fee - owned dwelling units as an alternative to both condominium ownership and traditional single-family detached subdivision. Unit lot subdivisions determine compliance with the relevant dimensional standards of ECDC Title 16 by analyzing whether the parent lot complies, but not requiring that each newly created lot within the unit lot subdivision (the unit lot) complies, with those dimensional standards. A unit lot subdivision does not permit uses or densities that are not otherwise allowed in the zoning district in which the unit lot subdivision is proposed. As described in the following sections, the proposed preliminary plat meets the purposes of the unit lot standards. 2. Applicability. The provisions of this section apply exclusively to the subdivision of land for single-family dwelling units, townhouse, and rowhouses and may be applied only in the following zones: multiple residential, general commercial, and Westgate mixed -use. A single lot within a unit lot subdivision may contain multiple dwelling units when the unit lot contains all such dwelling units within one building. Flats are permitted as an element of a unit lot subdivision only when a single lot within a unit lot subdivision contains the entire building in which flats are located. The site is zoned Multifamily Residential (RM-2.4) and the development consists of 11 stand-alone dwelling units around a central access tract. A dwelling unit and area of privately -owned open space will be contained within each unit lot (Attachment 4). No flats are proposed, as can be seen on the proposed plan sheets from a representative building permit (Attachment 5). Each of the dwelling units is organized similarly and contains two levels of living space about a two -car garage. 3. Association with Site Development — Application Timing. In the case of a vacant lot or a redevelopment site, a preliminary unit lot subdivision can only be submitted in conjunction with or subsequent to a development site plan as required by Chapter 20.10, 20.11, or 20.12 ECDC, or in the case described in ECDC 20.10.020(8)(3) submitted in conjunction with or subsequent to a building permit. The Architectural Design Board reviewed the design of the infill project and issued approval on June 21, 2017 (PLN20170017). The associated building permits (civil site improvements in BLD20171333 and dwelling units in BLD20171334 — BLD20171344) are currently under review. 244th Street Preliminary Unit Lot Plat File No. PLN20170047 Page 4 of 13 Packet Pg. 6 2.1.a 4. Conformance with Standards of the Parent Lot. The parent lot must comply with and is vested to the applicable development standards (ECDC20.75.030(E)) in effect at the time a complete application for preliminary unit lot subdivision is submitted. As a result of the unit lot subdivision, the individual unit lots within the subdivision may be nonconforming with respect to the bulk and dimensional standards required by ECDC Title 16. As with dimensional standards, compliance with access standards, including but not limited to fire lanes, drive aisles, turn-arounds, and access of/to the parent lot from/to the street will be evaluated based on the parent lot's compliance with such requirements, and not based on whether individual unit lots meet such standards. ECDC 16.30.030 contains the site development standards applicable to the subdivision (distances in feet): Minimum Minimum Zone Lot Area Street per DU Setback RM-2.4 2,400 sq. 15 ft. Minimum Minimum Side Rear Setback Setback 10 15 Maximum ' Maximum Height Coverage 25 + 51 45% 1 Roof only may extend five feet above the stated height limit if all portions of the roof above the stated height limit have a slope of four inches in 12 inches or greater. Setbacks: The project site has a street setback from the south property line, side setbacks on the east and west, and a rear setback from the north. As shown on the preliminary plat map in Attachment 4, the exterior of the project meets the required setbacks. The units have small patios within their private open space areas which project slightly into required setbacks. Per ECDC 16.30.010.C.2, patios may encroach into required setbacks 1/3 of the required distance or 4 feet, whichever is less. The patio projections shown satisfy that exception. Per ECDC 16.30.010.C.1, eaves, chimneys and similar minor improvements may also project into required setbacks up to 30 inches. A number of the buildings have projecting eaves which meet the exception. There is no parking located within a street setback as prohibited by ECDC 16.30.030.C. MaxlnlL1111 Coverage: The maximum structural lot coverage for the zone is 45%. As shown on the preliminary plat map in Attachment 4, buildings will cover 15,224 sq. ft., which is 39% of the parent lot area of 39,012 sq. ft. 244th Street Preliminary Unit Lot Plat File No. PLN20170047 Page 5 of 13 Packet Pg. 7 2.1.a Height: Height will be verified by staff with each of the building permits (BLD20171334 — BKD20171344). Future Additions and Modifications. Subsequent platting actions, additions or modifications to the structure(s) may not create or increase any nonconformity of the parcel lot. Changes requiring permitting that affect only the interior of building units will be evaluated for compliance with the requirements only for that unit. Any exterior changes will be evaluated for compliance by considering whether the parent lot would still comply with applicable development standards. Any application for such external changes will require authorization of all owners of affected unit lots or approval of the HOA where changes to commonly owned tracts are proposed. Documentation describing how additions and modifications are managed by the homeowners' association created for the project will be required with the submittal of the final plat. 6. Homeowners' Association Ownership of Common Areas. Any commonly used areas or facilities within a unit lot subdivision, including but not limited to common access, garage or parking areas, common open space or recreation space, common courtyards, commonly used storm water facilities or side sewers and other similar features, must be owned and maintained by a homeowners' association with the right to assess the individual unit lot owners as necessary to properly maintain and repair such areas. Appropriate documentation regarding the rights of the homeowners association must be submitted for recording with the final plat. Documentation describing the homeowners' association will be required with the submittal of the final plat for the project. 7. Maintenance Agreements for Building Exteriors. Maintenance agreements must be executed and recorded as an element of the final unit subdivision plat or short plat for maintenance of all building exteriors except in cases where all dwelling units are detached. The maintenance agreement must require equal participation by all owners within any one building and must be recorded on the final unit lot plat. The requirement does not apply to detached single family dwelling units. Common wall construction must meet currently adopted building codes. Because the 11 dwelling units are detached, maintenance agreements for building exteriors are not required with the submittal of the final plat for the project. Each homeowner will be responsible for the exterior of the building on their lot. 8. Parking on Different Unit Lots Allowed. Within the parent lot, required parking for a dwelling unit may be provided on a different unit lot than the lot with the dwelling unit as long as the right to use that parking is formalized by an easement on the final plat. 244th Street Preliminary Unit Lot Plat File No. PLN20170047 Page 6 of 13 Packet Pg. 8 2.1.a The 11 dwelling units each require two off-street parking spaces for a total of 22 stalls. Each unit has a two car garage so the minimum requirement is met. An additional 10 off-street guest stalls are proposed throughout the site (Attachment 4). Easements must be established for these stalls and a condition to that effect is proposed. The use and maintenance of the guest parking stalls must be described in the homeowners' association documentation. 9. Notice of Unit Lot on the Final Plat. The fact that the unit lot is not a separate buildable lot and that additional development of the individual unit lots may be limited as a result of the application of development standards to the parent lot must be noted on the final plat. A note to this effect must be added to the face of the final plat. 10. An application for final unit lot plat will not be accepted until all foundations, including common wall foundations, are installed and located on the face of the final plat by the land surveyor of record. A condition to this effect is proposed. 11. Review. Unit lot subdivisions of four or fewer lots are processed and reviewed as short subdivisions while five or more lots are formal subdivisions pursuant to Chapter 20.01 ECDC and the requirements of this chapter. As noted previously, this is an 11-lot plat with access tract and so is a formal unit lot subdivision where the Hearing Examiner issues the Type III-B decision on the preliminary plat. E. ECDC 20.75.080 General Findings A proposed subdivision may only be approved if all the general findings listed in ECDC 20.75.080 can be made for the proposal as approved or as conditionally approved. Staff's findings in regard to ECDC 20.75.080 are described below. 1. Subdivision Ordinance. The proposal is consistent the purposes of this chapter (ECDC 20.75) and meets all requirements of this chapter. The proposed unit lot subdivision is consistent with Sections 20.75.020 and 20.75.045.A and 045.13 ECDC. The proposed subdivision will not negatively impact public health, safety or general welfare, will not negatively impact congestion on streets and highways, has adequate access to water, utilities, sewerage, storm drainage and provides proper ingress and egress and will be uniformly monumented. The anticipated improvements are currently under review by staff and the improvements can only be constructed if staff finds that the permits satisfy all applicable code requirements. 2. Comprehensive Plan. The proposal is consistent with the provisions of the Edmonds Comprehensive Plan, or other adopted city policy, and is in the public interest. 244th Street Preliminary Unit Lot Plat File No. PLN20170047 Page 7 of 13 Packet Pg. 9 2.1.a The Comprehensive Plan designation for this site is "Multi Family — Medium Density". Applicable goals, objectives and policies in the 2016 Comprehensive Plan include: Sustainability Goal G Develop housing policies, programs, and regulations designed to support and promote sustainability. Support and encourage a mix of housing types and styles which provide people with affordable housing choices geared to changes in life style. Housing Goal F Provide for a variety of housing that respects the established character of the community. F.1. Expand and promote a variety of housing opportunities by establishing land use patterns that provide a mixture of housing types and densities. F.1.b. Provide for mixed use, multifamily and single family housing that is targeted and located according to the land use patterns established in the land use element. Residential Goal A High quality residential development which is appropriate to the diverse lifestyle of Edmonds residents should be maintained and promoted. The options available to the City to influence the quality of housing for all citizens should be approached realistically in balancing economic, social, aesthetic and environmental considerations. Residential Goal B A broad range of housing types and densities should be encouraged in order that a choice of housing will be available to all Edmonds residents, in accordance with the following policies: B.2 Multiple. The City's development policies encourage sustainable high quality site and building design to promote coordinated development and to preserve the trees, topography and other natural features of the site. Stereotyped, boxy multiple unit residential (RM) buildings are to be avoided. The proposed unit lot plat will create additional home ownership opportunities in a transitioning area served by transit between Firdale Village and Highway 99. The unit lot sites should be relatively more affordable than traditional single family development because the parcels and dwelling units are smaller. While the site could be platted through the condominium process (which the City does not review), the City is able to review the unit lot plat and related maintenance agreements and homeowners' association documents to ensure that future maintenance of the development is appropriately addressed. 24411 Street Preliminary Unit Lot Plat File No. PLN20170047 Page 8 of 13 Packet Pg. 10 2.1.a The overall proposal should not cause any adverse impacts and appears to be consistent with the residential development goals and policies of the Comprehensive Plan. Therefore, staff finds that the proposal is consistent with the Comprehensive Plan and is in the public interest. 3. Zoning Ordinance. The proposal meets all requirements of the zoning ordinance, or a modification has been approved as provided for in this chapter. Staff finds the proposal is consistent with the zoning requirements for the RM- 2.4 zone (ECDC 16.30). No modification requests were proposed. 4. Flood Plain Management. The proposal meets all requirements of the Edmonds Community Development code relating to flood plain management. The proposed project is not located within a designated flood plain management area. F. ECDC 20.75.085 — Review Criteria. Pursuant to ECDC 20.75.085, the following criteria shall be used to review proposed subdivisions: 1. Environmental. a. Where environmental resources exist, such as trees, streams, ravines or wildlife habitats, the proposal shall be designed to minimize significant adverse impacts to resources. Permanent restrictions may be imposed on the proposal to avoid impact. b. The proposal shall be designed to minimize grading by using shared driveways and by relating street, house site and lot placement to the existing topography. c. Where conditions exist which could be hazardous to the future residents of the land to be divided, or to nearby residents or property, such as flood plains, steep slopes or unstable soil or geologic conditions, a subdivision of the hazardous land shall be denied unless the condition can be permanently corrected, consistent with paragraphs A(1) and (2) of this section. d. The proposal shall be designed to minimize off -site impacts on drainage, views and so forth. The dwelling units and site improvements could be constructed whether or not individual fee -simple lots were created for each unit. There will be no change to the buildings and site improvements through this unit lot plat (if the building permits are eventually approved) so there will be no additional environmental impacts. 2. Lot and Street Layout. a. Lots shall be designed to contain a usable building area. If the building area would be difficult to develop, the lot shall be redesigned or eliminated, unless special conditions can be imposed on the approval which will ensure that the lot is developed properly. 244th Street Preliminary Unit Lot Plat File No. PLN20170047 Page 9 of 13 Packet Pg. 11 2.1.a Each of the proposed unit lots will contain a dwelling unit and a small private yard. b. Lots shall not front on highways, arterials or collector streets unless there is no other feasible access. Special access provisions, such as shared driveways, turnarounds or frontage streets may be required to minimize traffic hazards. All 11 proposed unit lots will access the central drive aisle (Tract 999) which connects with 2441h Street SW. This arrangement was approved as part of the associated design review and is being reviewed with the associated building permits. c. Each lot shall meet the applicable dimensional requirements of the zoning ordinance. Since this is a unit lot plat, the parent lot must comply with the development standards for the zone but the individual unit lots do not. In this case, there is no minimum lot width requirement in the RM-2.4 zone. The minimum lot area requirement of 2,400 sq. ft. per dwelling unit is met across the parent parcel. The parent lot is 39,012 sq. ft. and dividing by 2,400 sq. ft. would yield a maximum of 16 possible dwelling units at the site; 11 units are proposed. d. Pedestrian walks or bicycle paths shall be provided to serve schools, parks, public facilities, shorelines and streams where street access is not adequate Sidewalks currently exist along both sides of 244t' Street SW. Per the City Engineering Division requirements (Attachment 21), the existing sidewalks adjacent to the development will be reconstructed to current standards as part of the project. 3. Dedications a. The city council may require dedication of land in the proposed subdivision for public use. Only the city council may approve a dedication of park land to satisfy the requirements of ECDC 20.75.090. The council may request a review and written recommendation from the planning advisory board. c. Any approval of a subdivision shall be conditioned on appropriate dedication of land for streets, including those on the official street map and the preliminary plat. No dedications are required nor offered. 4. Improvements. a. Improvements which may be required, but are not limited to, streets, curbs, pedestrian walks and bicycle paths, sidewalks, street landscaping, water lines, sewage systems, drainage systems and underground utilities. 244th Street Preliminary Unit Lot Plat File No. PLN20170047 Page 10 of 13 Packet Pg. 12 2.1.a b. The person or body approving a subdivision shall determine the improvements necessary to meet the purposes and requirements of this chapter, and the requirements of: i. ECDC Title 18, Public Works Requirements; ii. Chapter 19.75, Fire Code, as to fire hydrants, water supply and access. This determination shall be based on the recommendations of the community development director, the public works director, and the fire chief. All civil improvements for the site are currently under review through building permit BLD20171333. The permit has not been issued and improvements have not been constructed. If approved, construction per plan will be verified by field inspections. c. The use of septic systems maybe approved if all of the following conditions are met: i. It is more than 200 feet, multiplied by the number of lots in the proposed subdivision, from the nearest public sewer main to the nearest boundary of the land to be divided. ii. The land to be divided is zoned RS-20. iii. The public works director and city health officer determine that soil, drainage and slope conditions are satisfactory for septic use and that all requirements of WAC 248-96-090 are met. No septic systems are proposed. 5. Flood Plain Management. All subdivisions shall comply with the criteria set forth in the Edmonds community Development code for flood plain management. The subject property is not located within a Flood Plain Management area. G. ECDC 20.75.090 — Park Land Dedication. According to ECDC 20.75.090, before or concurrent with the approval of the final plat of any subdivision, the subdivider shall dedicate land, pay a fee in -lieu of dedication, or do a combination of both, for park and recreational purposes. With the adoption of Ordinance 3934 in 2013, park impacts are addressed through the assessment of park impact fees in accordance with Edmonds City Code (ECC) Chapter 3.36. Park impact fees will be assessed for the 244th Street buildings at the time of issuance of building permits (Attachment 11). IV.

Call (425) 771-0220- Revised on 8122112 B - Land Use Application Page I of I Attachment 1 - PLN20170047 Packet Pg. 16 2.1.a SEP 232017 CFiIELOPivjc-NT SERVICFg C(3,!NrFf-i INSIGHT ENGINEERING CO. i 244TH ST — COVER LETTER The proposed project 244th St is located at 8609 244th SW, Edmonds in Snohomish County, Washington. The site is currently developed with three houses, a garage, a shop, and two sheds. The remainder of the site is trees, landscaping, and access drives. This proposal is for 11 detached single-family dwelling units on one 0.90 acre lot, in a unit -lot subdivision. Zoning The standards for RM 2.4 are being followed for this project. The minimum number of square feet per unit is 2400. The lot is 39,012 square feet. Thus, the maximum number of units would be 16. As previously stated, this proposal is for 11 unit lots, which is well within the limit. The setbacks shown follow the zone, with 15 feet at the rear of the lot, 10 feet at the sides, and 15 feet at the front. As this is a unit -lot subdivision, setbacks apply only to the parent lot and not to the individual unit lots within it. The building height has a maximum of just under 29 feet. While the standard maximum height is 25 feet, per ECDC 16.030.A(1), a building may have an additional 5 feet of height if all the roof above 25 feet has a slope of at least 4 inches in 12 inches of greater. Per our attached building elevations, this condition will be met, thus our buildings follow the code. The buildings as shown cover 14,579 square feet, or 37.37% of the lot, below the maximum lot coverage of 45%. As previously stated, as this is a unit lot subdivision, if the parent lot meets standards, the unit lots within are not subject to the lot coverage standards. In addition, while some of the units have patios that protrude into the setback area, these never protrude more than 40 inches, or 3.33 feet, in the case of the side yards, or 4 feet in the case of the rear yard. Parkin Each unit has two parking spaces, provided per ECDC 17.50.020.A. In addition, 10 guest spaces have been provided. Landscaping Landscaping has been provided per the landscaping code, see the landscape plan. While, because of all the units being on one lot, the project needs to file under multifamily/townhome, in spirit, it is a single-family development. It is not a super -dense project. The homes will be two stories high. Thus, because of these factors, type II landscape buffers have been provided on all sides that border other lots, with type III landscaping between the buildings and the street. Comprehensive Plan This proposal is in the spirit of the goals of the residential policy of the comprehensive plan. The proposal does not impose upon the view of others, being only two stories high. The site presents few environmental constraints. Finally, every effort is being made to harmonize the proposal with the existing neighborhoods around it. In addition, this proposal could be considered infill, given the site's current zoning versus its current use.

Established setbacks have been followed, buildings are oriented toward the internal street, and landscaping has been used to soften sharp edges around the site. Overall, this letter demonstrates that not only does the proposal meet zoning requirements; it also meets the intent of the code and the comprehensive plan.

An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions for Applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of checklist for nonproject proposals: For nonproject proposals complete this checklist and the supplemental sheet for nonproject actions (Part D). the lead agency may exclude any question for the environmental elements (Part B) which they determine do not contribute meaningfully to the analysis of the proposed nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposer," and "affected geographic area," respectively.

More generally, the site is located in Section 31, Township 27 North, and Range 4 East of the Willamette Meridian in Snohomish County, Washington. Please refer to the Vicinity Map attached later in the section. This report follows the City of Edmond's requirements and the requirements defined in DOE's 2012 SWMMWW as amended in Dec 2014. The existing site contains three existing houses with garage, shed and an existing asphalt driveway from the 244th St. S. W. The third house has a shop attached to the shed and an existing gravel driveway from the 244th St. S. W. The remainder of the site contains lawn and few trees. The site is generally flat and appears to slope slightly towards the north. Please refer to the downstream analysis map for more details. Per NRCS survey of Snohomish County, the project site contains Alderwood soil that have a hydrologic classification of Type "C". Please refer to the soils map and descriptions attached later in this report for more details. The site area contains 0.90 Acres. The proposal is to construct eleven new single family homes and an access drive aisle from 244th St. SW. The project is greater than 5,000 SF, and therefore per Figure 2.2, (flow chart for new development requirements) Volume I SWMMWW, Minimum requirements #1 through 9 shall apply for this project. The yard and roof drains will be connected towards the pervious pavement. Flow Control (MR#7) and Onsite Stormwater Management (MR#5) requirements will be met by full infiltration using pervious asphalt provided under the private road. An infiltration rate of 0.75-in/hr was used for the hydraulic calculations per the recommendations from the Geotech report attached under the Appendix D. For water quality supplementing the underlying soils with a soil that meets the water quality objective is proposed. The pervious asphalt requires a minimum value of 5meg/100g towards Cation Exchange capacity for water quality. The construction plans specify supplementing the underlying soils with a soil that meets the water quality objective. See "Permeable Asphalt Pavement" detail on construction plan sheet C3.0. Post -Construction Soil Quality and Depth BMP T.5.13 are proposed towards additional onsite stormwater management.

Refer to the executive summary within Section 1.0 . MR #2 SWPPP Narrative: A SWPPP has been included in the Appendix B under Section 6. MR #3 Water Pollution Source Control for New Development: No source control pollutants pertains to the proposed single family project, therefore no BMP's are required for the project. MR #4 Preservation of Natural Drainage Systems and Outfalls: Pervious asphalt allows the runoff to be directly infiltrated into ground. Therefore no drainage is anticipated to leave the site. The overflow will discharge to a dispersion trench to drain to the north and continue the natural drainage path of the site. MR #5 Onsite Stormwater Management: The yard and roof drains will be connected towards the pervious pavement. Post -Construction Soil Quality and Depth BMP T.5.13 are proposed towards additional onsite stormwater management. Refer to Appendix E for the soil amendment calculation. MR #6 Runoff Treatment: For water quality supplementing the underlying soils with a soil that meets the water quality objective is proposed. The pervious asphalt requires a minimum value of 5meg/100g towards Cation Exchange capacity for water quality.

Page 18 Attachment 10 - PLN20170047 Packet Pg. 126 2.1.a 2.1.3 Element 3: Control Flow Rates In order to protect the properties and waterways downstream of the project site, stormwater discharges from the site will be controlled. In general, discharge rates of stormwater from the site will be controlled where increases in impervious area or soil compaction during construction could lead to downstream erosion, or where necessary to meet local agency stormwater discharge requirements (e.g. discharge to combined sewer systems). Will you construct stormwater retention and/or detention facilities? Yes ❑ No Will you use permanent infiltration ponds or other low impact development (example: rain gardens, bio-retention, porous pavement) to control flow during construction? ® Yes❑ No List and describe BMPs: Temporary Sediment Trap (BMP C240) Installation Schedules: Construct the temporary sediment trap, according to the approved construction plans, prior to any grading activities. ;r spection and Maintenance Plan: Maintain until the upper gadiant areas of the lot have been stabilized. Responsible Staff. Contractor %4 g 9 Attachment 10 - PLN20170047 Packet Pg. 127 2.1.a 2.1.4 Element 4: Install Sediment Controls Whenever possible, sediment laden water shall be discharged into onsite, relatively level, vegetated areas (BMP C240 paragraph 5, page 4-102). La some cases, sediment discharge in concentrated runoff can be controlled using permanent stormwater BMPs (e.g., infiltration swales, ponds, trenches). Sediment loads can limit the effectiveness of some permanent stormwater BMPs, such as those used for infiltration or bio- filtration; however, those BMPs designed to remove solids by settling (wet ponds or detention ponds) can be used during the constniction phase. When permanent stormwater BMPs will be used to control sediment discharge during construction, the structure will be protected from excessive sedimentation with adequate erosion and sediment control BMPs. Any accumulated sediment shall be removed after construction is complete and the permanent stormwater BMP will be re -stabilized with vegetation per applicable design requirements once the remainder of the site has been stabilized. The following BMP will be implemented as end -of -pipe sediment controls as required to meet permitted turbidity limits in the site discharge(s). Prior to the implementation of these technologies, sediment sources and erosion control and soil stabilization BMP efforts will be maximized to reduce the need for end -of -pipe sedimentation controls. In addition, sediment will be removed from paved areas in and adjacent to construction work areas manually or using mechanical sweepers, as needed, to minimize tracking of sediments on vehicle tires away from the site and to minimize wash -off of sediments from adjacent streets in runoff. List and describe BMPs: Storm Drain Inlet Protection (BMP C220) Temporary Sediment Trap (BMP C240) Silt Fence (BMP C233) Installation Schedules: Install silt fencing, according to the approved plans, prior to any clearing or grading activities. Install catch basin filters, according to the approved construction plans, as catch basins are installed and become operable. Construct the temporary sediment trap, according to the approved construction plans, prior to any grading activities. Inspection and Maintenance plan: Maintain Silt Fence and Storm Drain Inlet Protection until all construction activities are completed. Maintain Temporary Sediment Trap until the upper gadiant areas of the lot have been stabilized. Responsible Staff: Contractor. P Esg10 Attachment 10 - PLN20170047 Packet Pg. 128 2.1.a 2.1.5 Element 5: Stabilize Soils The project site is located west of the Cascade Mountain Crest. As such, no soils shall remain exposed and unworked for more than 7 days during the dry season (May 1 to September 30) and 2 days during the wet season (October 1 to April 30). Regardless of the time of year, all soils shall be stabilized at the end of the shift before a holiday or weekend if needed based on weather forecasts. In general, cut and fill slopes will be stabilized as soon as possible and soil stockpiles will be temporarily covered with plastic sheeting. All stockpiled soils shall be stabilized from erosion, protected with sediment trapping measures, and where possible, be located away from storm drain inlets, waterways, and drainage channels.

Anticipated project dates: Start date: May 1, 2018 End date: March 10, 2019 Will you construct during the wet season? YU Yes❑ No List and describe BMPs: Exposed and un-worked soils shall be stabilized with the application of effective BMPs to prevent erosion throughout the life of the project. The specific BMPs for soil stabilization that shall be used on this project include: Temporary and Permanent Seeding (BMP C120) Installation Schedules: Apply temporary hydro -seed to exposed and un-worked soils, according to the approved construction plans, as needed to prevent erosion during site grading. Inspection and Maintenance plan: Apply permanent hydro -seed to areas at final grade as site grading is completed. • Mulching (BMP C 121) Installation Schedules: Apply mulching to exposed and un-worked soils, according to the approved construction plans, as needed to prevent erosion during site grading. Inspection and Maintenance plan: Maintain until site grading is completed and permanent hydro -seed is applied. • Plastic Covering (BMP C123) Installation Schedules: Cover stockpiles with plastic sheeting, according to the approved construction plans, as needed to prevent erosion during site grading. FF < �� - �.; ., 111 Attachment 10 - PLN20170047 Packet Pg. 129 2.1.a Inspection and Maintenance plan: Maintain until stockpiles are removed from site. • Dust Control (BMP C140) Installation Schedules and Inspection and Maintenance plan: ❑ Vegetate or mulch areas that will not receive vehicle traffic. In areas where planting, mulching, or paving is impractical, apply gravel or landscaping rock. ❑ Limit dust generation by clearing only those areas where immediate activity will take place, leaving the remaining area(s) in the original condition. Maintain the original ground cover as long as practical. ❑ Construct natural or artificial windbreaks or windscreens. These may be designed as enclosures for small dust sources. ❑ Sprinkle the site with water until surface is wet. Repeat as needed. To prevent carryout of mud onto street, refer to Stabilized Construction Entrance (BMP C 105). ❑ Irrigation water can be used for dust control. Irrigation systems should be installed as a first Step on sites where dust control is a concern. ❑ Spray exposed soil areas with a dust palliative, following the manufacturer's instructions and cautions regarding handling and application. Used oil is prohibited from use as a dust suppressant. Local governments may approve other dust palliatives such as calcium chloride or PAM. ❑ PAM (BMP C126) added to water at a rate of 0.5 lbs. per 1,000 gallons of water per acre and applied from a water truck is more effective than water alone. This is due to increased infiltration of water into the soil and reduced evaporation. In addition, small soil particles are bonded together and are not as easily transported by wind. Adding PAM may actually reduce the quantity of water needed for dust control. Use of PAM could be a cost-effective dust control method. Techniques that can be used for unpaved roads and lots include: ❑ Lower speed limits. High vehicle speed increases the amount of dust stirred up from unpaved roads and lots. ❑ Upgrade the road surface strength by improving particle size, shape, and mineral types that make up the surface and base materials. ❑ Add surface gravel to reduce the source of dust emission. Limit the amount of fine particles (those smaller than .075 mm) to 10 to 20 percent. ❑ Use geotextile fabrics to increase the strength of new roads or roads undergoing reconstruction. ❑ Encourage the use of alternate, paved routes, if available. ❑ Restrict use of paved roadways by tracked vehicles and heavy trucks to prevent damage to road surface and base, ❑ Apply chemical dust suppressants using the admix method, blending the product with the top few inches of surface material. Suppressants may also be applied as surface treatments. Pave unpaved permanent roads and other trafficked areas. ❑ Use vacuum street sweepers. ❑ Remove mud and other dirt promptly so it does not dry and then turn into dust. ❑ Limit dust -causing work on windy days. Page 112 Attachment 10 - PLN20170047 Packet Pg. 130 2.1.a ❑ Contact your local Air Pollution Control Authority for guidance and training on other dust control measures. Compliance with the local Air Pollution Control Authority constitutes compliance with this BMP. • Early application of gravel base on areas to be paved Place gravel base on roadways, according to the approved construction plans, after roadways are graded to sub -grade. Maintain until roads are paved. Responsible Staff. Contractor.

Contractor Page 114 Attachment 10 - PLN20170047 Packet Pg. 132 2.1.a 2.1.7 Element 7: Protect Drain Inlets All storm drain inlets and culverts made operable during construction shall be protected to prevent unfiltered or untreated water from entering the drainage conveyance system. However, the first priority is to keep all access roads clean of sediment and keep street wash water separate from entering storm drains until treatment can be provided. Storm Drain Inlet Protection (BMP C220) will be implemented for all drainage inlets and culverts that could potentially be impacted by sediment -laden runoff on and near the project site.

If any BMP's are provideded, the project site is located west of the Cascade Mountain Crest. As such, all temporary on -site conveyance channels shall be designed, constructed, and stabilized to prevent erosion from the expected peak 10 minute velocity of flow from a Type IA, 10-year, 24- hour recurrence interval storm for the developed condition. Alternatively, the 10-year, 1-hour peak flow rate indicated by an approved continuous runoff simulation model, increased by a factor of 1.6, shall be used. Stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent stream banks, slopes, and downstream reaches shall be provided at the outlets of all conveyance systems. Provide stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent stream banks, slopes, and downstream reaches, will be installed at the outlets of all conveyance systems.

Concrete and grout: ❑ Process water and slurry resulting from concrete work will be prevented from entering the waters of the State by implementing Concrete Handling measures (BMP C 151). Sanitary wastewater: F1 Portable sanitation facilities will be firmly secured, regularly maintained, and emptied when necessary. Solid Waste: ❑ Solid waste will be stored in secure, clearly marked containers. Other: ❑ Other BMPs will be administered as necessary to address any additional pollutant sources on site. A SPCC plan is required for this site. As per the Federal regulations of the Clean Water Act (CWA) and according to Final Rule 40 CFR Part 112, as stated in the National Register, a Spill Prevention, Control, and Countermeasure (SPCC) Plan is required for construction activities. A SPCC Plan has been prepared to address an approach to prevent, respond to, and report spills or releases to the environment that could result from construction activities. This Plan must: ❑ Be well thought out in accordance with good engineering; List and describe BMPs: BMP C151, BMP C152, BMP C153, BMP C140 and BMP C220. Installation Schedules: Inspection and Maintenance plan: All pollutants, including waste materials and demolition debris, that occur onsite shall be handled and disposed of in a manner that does not cause contamination of stormwater. Good housekeeping and preventative measures will be taken to ensure that the site will be kept clean, well organized, and free of debris. Achieve three objectives - prevent spills, contain a spill that occurs, and clean up the spill; ❑ Identify the name, location, owner, and type of facility; Include the date of initial operation and oil spill history; ❑ Name the designated person responsible; ❑ Show evidence of approval and certification by the person in authority; and ❑ Contain a facility analysis.

Transparency is 33 cm (or greater). Compliance with the water quality limit for turbidity is achieved. 0 1 - 5 NTU over background turbidity, if background is less than 50 NTU 0 1% - 10% over background turbidity, if background is 50 NTU or greater • The discharge stops or is eliminated. y;28 Attachment 10 - PLN20170047 Packet Pg. 138 2.1.a 4.2.2 pH Sampling pH monitoring is required for "Significant concrete work" (i.e., greater than 1000 cubic yards poured concrete over the life of the project). The use of recycled concrete or engineered soils (soil amendments including but not limited to Portland cement -treated base [CTB], cement kiln dust [CKD] or fly ash) also requires pH monitoring. For significant concrete work, pH sampling will start the first day concrete is poured and continue until it is cured, typically three (3) weeks after the last pour. For engineered soils and recycled concrete, pH sampling begins when engineered soils or recycled concrete are first exposed to precipitation and continues until the area is fully stabilized. If the measured pH is 8.5 or greater, the following measures will be taken: 1. Prevent high pH water from entering storm sewer systems or surface water. 2. Adjust or neutralize the high pH water to the range of 6.5 to 8.5 su using appropriate technology such as carbon dioxide (CO2) sparging (liquid or dry ice). 3. Written approval will be obtained from Ecology prior to the use of chemical treatment other than CO2 sparging or dry ice.

A copy of the SWPPP or access to the SWPPP will be provided to the public when requested in writing in accordance with Special Condition S5.G.2.b of the CSWGP. 6.1.3 Updating the SWPPP The SWPPP will be modified if- * Found ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. • There is a change in design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutants to waters of the State. The SWPPP will be modified within seven (7) days if inspection(s) or investigation(s) determine additional or modified BMPs are necessary for compliance. An updated timeline for BMP implementation will be prepared. 6.2 Reporting 6.2.1 Discharge Monitoring Reports Cumulative soil disturbance is one (1) acre or larger; therefore, Discharge Monitoring Reports (DMRs) will be submitted to Ecology monthly. If there was no discharge during a given Page 131 Attachment 10 - PLN20170047 Packet Pg. 141 2.1.a monitoring period the DMR will be submitted as required, reporting "No Discharge". The DMR due date is fifteen (15) days following the end of each calendar month. DMRs will be reported online through Ecology's WQWebDMR System. 6.2.2 Notification of Noncompliance If any of the terms and conditions of the permit is not met, and the resulting noncompliance may cause a threat to human health or the environment, the following actions will be taken: 1. Ecology will be notified within 24-hours of the failure to comply by calling the applicable Regional office ERTS phone number "Regional office numbers listed below). 2. Immediate action will be taken to prevent the discharge/pollution or otherwise stop or correct the noncompliance. If applicable, sampling and analysis of any noncompliance will be repeated immediately and the results submitted to Ecology within five (5) days of becoming aware of the violation. 3.

Disease can become established through damaged limbs, trunks, roots, and freshly cut stumps. Diseased and weakened trees are also susceptible to insect attack. Maintenance Standards Inspect flagged and/or fenced areas regularly to make sure flagging or fencing has not been removed or damaged. If the flagging or fencing has been damaged or visibility reduced, it shall be repaired or replaced immediately and visibility restored. . If tree roots have been exposed or injured, "prune" cleanly with an appropriate prun- ing saw or loppers directly above the damaged roots and recover with native soils. Treatment of sap flowing trees (fir, hemlock, pine, soft maples) is not advised as sap forms a natural healing barrier. BMP C102: Buffer Zones Purpose Creation of an undisturbed area or strip of natural vegetation or an established suitable planting that will provide a living filter to reduce soil erosion and runoff velocities. Conditions of Use Natural buffer zones are used along streams, wetlands and other bodies of water that need protection from erosion and sedimentation. Vegetative buffer zones can be used to protect natural swales and can be incorporated into the natural landscaping of an area. Critical -areas buffer zones should not be used as sediment treatment areas. These areas shall remain completely undisturbed. The local permitting authority may expand the buffer widths temporarily to allow the use of the expanded area for removal of sed- iment. Design and Installation Specifications Preserving natural vegetation or plantings in clumps, blocks, or strips is generally the easiest and most successful method. . Leave all unstable steep slopes in natural vegetation. . Mark clearing limits and keep all equipment and construction debris out of the nat- ural areas and buffer zones. Steel construction fencing is the most effective method in protecting sensitive areas and buffers. Alternatively, wire -backed silt fence on steel posts is marginally effective. Flagging alone is typically not effective. . Keep all excavations outside the dripline of trees and shrubs. Do not push debris or extra soil into the buffer zone area because it will cause 2014 Stormwater Management Manual for Western Washington Volume // - Chapter 4 - Page 268 Attachment 10 - PLN20170047 Packet Pg. 146 2.1.a damage from burying and smothering. Vegetative buffer zones for streams, lakes or other waterways shall be established by the local permitting authority or other state or federal permits or approvals. Maintenance Standards Inspect the area frequently to make sure flagging remains in place and the area remains undisturbed. Replace all damaged flagging immediately. BMP C103: laugh Visibility Fence Purpose Fencing is intended to: 1. Restrict clearing to approved limits. 2. Prevent disturbance of sensitive areas, their buffers, and other areas required to be left undisturbed. 3. Limit construction traffic to designated construction entrances, exits, or internal roads. 4. Protect areas where marking with survey tape may not provide adequate pro- tection. Conditions of Use To establish clearing limits plastic, fabric, or metal fence may be used: At the boundary of sensitive areas, their buffers, and other areas required to be left uncleared. . As necessary to control vehicle access to and on the site. Design and Installation Specifications High visibility plastic fence shall be composed of a high -density polyethylene material, and shall be at least four feet in height. Posts for the fencing shall be steel or wood and placed every 6 feet on center (maximum) or as needed to ensure rigidity. The fencing shall be fastened to the post every six inches with a polyethylene tie. On long continuous lengths of fencing, a tension wire or rope shall be used as a top stringer to prevent sag- ging between posts. The fence color shall be high visibility orange. The fence tensile strength shall be 360 lbs./ft. using the ASTM D4595 testing method. If appropriate install fabric silt fence in accordance with BMP C233: Silt Fence (p_.36to act as high visibility fence. Silt fence shall be at least 3 feet high and must be highly vis- ible to meet the requirements of this BMP. 2014 Stormwater Management Manual for Western Washington Volume ll - Chapter 4 - Page 269 Attachment 10 - PLN20170047 Packet Pg. 147 2.1.a Metal fences shall be designed and installed according to the manufacturer's spe- cifications. Metal fences shall be at least 3 feet high and must be highly visible. Fences shall not be wired or stapled to trees. Maintenance Standards If the fence has been damaged or visibility reduced, it shall be repaired or replaced immediately and visibility restored. BMP C105: Stabilized Construction Entrance / Exit Purpose Stabilized Construction entrances are established to reduce the amount of sediment transported onto paved roads by vehicles or equipment. This is done by constructing a stabilized pad of quarry spalls at entrances and exits for construction sites. Conditions of Use Construction entrances shall be stabilized wherever traffic will be entering or leaving a construction site if paved roads or other paved areas are within 1,000 feet of the site. For residential construction provide stabilized construction entrances for each residence, rather than only at the main subdivision entrance. Stabilized surfaces shall be of suf- f rient length/width to provide vehicle access/parking, based on lot size/configuration. On large commercial, highway, and road projects, the designer should include enough extra materials in the contract to allow for additional stabilized entrances not shown in the initial Construction SWPPP. It is difficult to determine exactly where access to these projects will take place; additional materials will enable the contractor to install them where needed. Design and Installation Specifications See Figure 11-4.1.1 Stabilized Construction Entrance .273 for details. Note: the 100' minimum length of the entrance shall be reduced to the maximum practicable size when the size or configuration of the site does not allow the full length (100'). Construct stabilized construction entrances with a 12-inch thick pad of 4-inch to 8-inch quarry spalls, a 4-inch course of asphalt treated base (ATB), or use existing pavement. Do not use crushed concrete, cement, or calcium chloride for construction entrance sta- bilization because these products raise pH levels in stormwater and concrete discharge to surface waters of the State is prohibited. 2014 Stormwater Management Manual for Western Washington Volume // - Chapter 4 - Page 270 Attachment 10 - PLN20170047 Packet Pg. 148 2.1.a . Storm drain inlets shall be protected to prevent sediment -laden water entering the storm drain system (see BMP C220: Storm Drain Inlet Protection .357 . Maintenance Standards Inspect stabilized areas regularly, especially after large storm events. Crushed rock, gravel base, etc., shall be added as required to maintain a stable driving surface and to stabilize any areas that have eroded. Following construction, these areas shall be restored to pre -construction condition or bet- ter to prevent future erosion. Perform street cleaning at the end of each day or more often if necessary. BMP C120: Temporary and Permanent Seeding Purpose Seeding reduces erosion by stabilizing exposed soils. A well -established vegetative cover is one of the most effective methods of reducing erosion. Conditions of Use Use seeding throughout the project on disturbed areas that have reached final grade or that will remain unworked for more than 30 days. The optimum seeding windows for western Washington are April 1 through June 30 and September 1 through October 1. Between July 1 and August 30 seeding requires irrigation until 75 percent grass cover is established. Between October 1 and March 30 seeding requires a cover of mulch with straw or an erosion control blanket until 75 percent grass cover is established. Review all disturbed areas in late August to early September and complete all seeding by the end of September. Otherwise, vegetation will not establish itself enough to provide more than average protection. Mulch is required at all times for seeding because it protects seeds from heat, mois- ture loss, and transport due to runoff. Mulch can be applied on top of the seed or simultaneously by hydroseeding. See BMP C 121: Mulching (p.284) for spe- cifications. . Seed and mulch, all disturbed areas not otherwise vegetated at final site sta- bilization. Final stabilization means the completion of all soil disturbing activities at the site and the establishment of a permanent vegetative cover, or equivalent per- 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter - Page 278 Attachment 10 - PLN20170047 Packet Pg. 149 2.1.a manent stabilization measures (such as pavement, riprap, gabions, or geotextiles) which will prevent erosion. Design and Installation Specifications Seed retention/detention ponds as required. Install channels intended for vegetation before starting major earthwork and hydroseed with a Bonded Fiber Matrix. For vegetated channels that will have high flows, install erosion control blankets over hydroseed. Before allowing water to flow in vegetated channels, establish 75 percent vegetation cover. If vegetated channels cannot be estab- lished by seed before water flow; install sod in the channel bottom —over hydromulch and erosion control blankets. . Confirm the installation of all required surface water control measures to prevent seed from washing away. . Hydroseed applications shall include a minimum of 1,500 pounds per acre of mulch with 3 percent tackifier. See BMP C 121: Mulching .284 for specifications. . Areas that will have seeding only and not landscaping may need compost or meal - based mulch included in the hydroseed in order to establish vegetation. Re -install native topsoil on the disturbed soil surface before application. . When installing seed via hydroseeding operations, only about 1/3 of the seed actu- ally ends up in contact with the soil surface. This reduces the ability to establish a good stand of grass quickly. To overcome this, consider increasing seed quantities by up to 50 percent. . Enhance vegetation establishment by dividing the hydromulch operation into two phases: 1. Phase 1- Install all seed and fertilizer with 25-30 percent mulch and tackifier onto soil in the first lift. 2. Phase 2- Install the rest of the mulch and tackifier over the first lift. Or, enhance vegetation by: 1. Installing the mulch, seed, fertilizer, and tackifier in one lift. 2. Spread or blow straw over the top of the hydromulch at a rate of 800-1000 pounds per acre. 3. Hold straw in place with a standard tackifier. Both of these approaches will increase cost moderately but will greatly improve and enhance vegetative establishment. The increased cost may be offset by the reduced need for: 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 279 Attachment 10 - PLN20170047 Packet Pg. 150 2.1.a Irrigation. 0 Reapplication of mulch. W Repair of failed slope surfaces. This technique works with standard hydromulch (1,500 pounds per acre minimum) and BFM/MBFMs (3,000 pounds per acre minimum). 6 Seed may be installed by hand if: . Temporary and covered by straw, mulch, or topsoil. . Permanent in small areas (usually less than 1 acre) and covered with mulch, topsoil, or erosion blankets. . The seed mixes listed in the tables below include recommended mixes for both temporary and permanent seeding. © Apply these mixes, with the exception of the wetland mix, at a rate of 120 pounds per acre. This rate can be reduced if soil amendments or slow - release fertilizers are used. . Consult the local suppliers or the local conservation district for their recom- mendations because the appropriate mix depends on a variety of factors, including location, exposure, soil type, slope, and expected foot traffic. Altern- ative seed mixes approved by the local authority may be used. 0 Other mixes may be appropriate, depending on the soil type and hydrology of the area.

Roughening and Rototilling: The seedbed should be firm and rough. Roughen all soil no matter what the slope. Track walk slopes before seeding if engineering purposes require 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 282 Attachment 10 - PLN20170047 Packet Pg. 153 2.1.a compaction. Backbiading or smoothing of slopes greater than 4H:1 V is not allowed if they are to be seeded. Restoration -based landscape practices require deeper incorporation than that provided by a simple single -pass rototilling treatment. Wherever prac- tical, initially rip the subgrade to improve long-term permeability, infiltration, and water inflow qualities. At a minimum, permanent areas shall use soil amendments to achieve organic matter and permeability performance defined in engineered soil/landscape systems. For systems that are deeper than 8 inches complete the rototilling process in multiple lifts, or prepare the engineered soil system per specifications and place to achieve the specified depth. Fertilizers: . Conducting soil tests to determine the exact type and quantity of fertilizer is recommended. This will prevent the over -application of fertilizer. . Organic matter is the most appropriate form of fertilizer because it provides nutrients (including nitrogen, phosphorus, and potassium) in the least water- soluble form. . In general, use 10-4-6 N-P-K (nitrogen -phosphorus -potassium) fertilizer at a rate of 90 pounds per acre. Always use slow -release fertilizers because they are more efficient and have fewer environmental impacts. Do not add fer- tilizer to the hydromulch machine, or agitate, more than 20 minutes before use. Too much agitation destroys the slow -release coating. . There are numerous products available that take the place of chemical fer- tilizers. These include several with seaweed extracts that are beneficial to soil microbes and organisms. If 100 percent cottonseed meal is used as the mulch in hydroseed, chemical fertilizer may not be necessary. Cottonseed meal provides a good source of long-term, slow -release, available nitrogen. . Bonded Fiber Matrix and Mechanically Bonded Fiber Matrix: On steep slopes use Bonded Fiber Matrix (BFM) or Mechanically Bonded Fiber Matrix (MBFM) products. Apply BFM/MBFM products at a minimum rate of 3,000 pounds per acre of mulch with approximately 10 percent tackifier. Achieve a minimum of 95 percent soil coverage during application. Numer- ous products are available commercially. Installed products per man- ufacturer's instructions. Most products require 24-36 hours to cure before rainfall and cannot be installed on wet or saturated soils. Generally, products come in 40-50 pound bags and include all necessary ingredients except for seed and fertilizer. 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 283 Attachment 10 - PLN20170047 Packet Pg. 154 2.1.a . BFMs and MBFMs provide good alternatives to blankets in most areas requir- ing vegetation establishment. Advantages over blankets include: . BFM and MBFMs do not require surface preparation. Helicopters can assist in installing BFM and MBFMs in remote areas. . On slopes steeper than 2.5H:1 V, blanket installers may require ropes and harnesses for safety. . Installing BFM and MBFMs can save at least $1,000 per acre com- pared to blankets. Maintenance Standards Reseed any seeded areas that fail to establish at least 80 percent cover (100 percent cover for areas that receive sheet or concentrated flows). If reseeding is ineffective, use an alternate method such as sodding, mulching, or nets/blankets. If winter weather pre- vents adequate grass growth, this time limit may be relaxed at the discretion of the local authority when sensitive areas would otherwise be protected. Reseed and protect by mulch any areas that experience erosion after achieving adequate cover. Reseed and protect by mulch any eroded area. Supply seeded areas with adequate moisture, but do not water to the extent that it causes runoff.

BMP C121: Mulching Purpose Mulching soils provides immediate temporary protection from erosion. Mulch also enhances plant establishment by conserving moisture, holding fertilizer, seed, and top- soil in place, and moderating soil temperatures. There is an enormous variety of mulches that can be used. This section discusses only the most common types of mulch. Conditions of Use As a temporary cover measure, mulch should be used: 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 284 Attachment 10 - PLN20170047 Packet Pg. 155 2.1.a . For less than 30 days on disturbed areas that require cover. . At all times for seeded areas, especially during the wet season and during the hot summer months. . During the wet season on slopes steeper than 3H:1 V with more than 10 feet of ver- tical relief. Mulch may be applied at any time of the year and must be refreshed periodically. For seeded areas mulch may be made up of 100 percent: cottonseed meal; fibers made of wood, recycled cellulose, hemp, kenaf; compost; or blends of these. Tack- ifier shall be plant -based, such as guar or alpha plantago, or chemical -based such as polyacrylamide or polymers. Any mulch or tackifier product used shall be installed per manufacturer's instructions. Generally, mulches come in 40-50 pound bags. Seed and fertilizer are added at time of application. Design and Installation Specifications For mulch materials, application rates, and specifications, see Table II-4.1.8 Mulch Standards and Guidelines .286 . Always use a 2-inch minimum mulch thickness; increase the thickness until the ground is 95% covered (i.e. not visible under the mulch layer). Note: Thickness may be increased for disturbed areas in or near sensitive areas or other areas highly susceptible to erosion. Where the option of "Compost" is selected, it should be a coarse compost that meets the following size gradations when tested in accordance with the U.S. Composting Council "Test Methods for the Examination of Compost and Composting" (TMECC) Test Method 02.02-B. Coarse Compost Minimum Percent passing 3" sieve openings 100% Minimum Percent passing 1"sieve openings 90% Minimum Percent passing 3/" sieve openings 70% Minimum Percent passing Y4" sieve openings 40% Mulch used within the ordinary high-water mark of surface waters should be selected to minimize potential flotation of organic matter. Composted organic materials have higher specific gravities (densities) than straw, wood, or chipped material. Consult Hydraulic Permit Authority (HPA) for mulch mixes if applicable. Maintenance Standards . The thickness of the cover must be maintained. Any areas that experience erosion shall be remulched and/or protected with a net 2014 Stormwater Management Manual for Western Washington Volume 11- Chapter 4 - Page 285 Attachment 10 - PLN20170047 Packet Pg. 156 2.1.a or blanket. If the erosion problem is drainage related, then the problem shall be fixed and the eroded area remulched.

BMP C122: 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 (commonly called matting) are strands of material woven into an open, but high -tensile strength net (for example, coconut fiber 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: . To aid permanent vegetated stabilization of slopes 2H:1 V or greater and with more than 10 feet of vertical relief. For drainage ditches and swales (highly recommended). The application of appro- priate netting or blanket to drainage ditches and swales can protect bare soil from channelized runoff while vegetation is established. Nets and blankets also can cap- ture a great deal of sediment due to their open, porous structure. Nets and blankets can be used to permanently stabilize channels and may provide a cost-effective, environmentally preferable alternative to riprap. 100 percent synthetic blankets manufactured for use in ditches may be easily reused as temporary ditch liners. Disadvantages of blankets include: . Surface preparation required. . On slopes steeper than 2.5H:1V, blanket installers may need to be roped and har- nessed for safety. . They cost at least $4,000-6,000 per acre installed. Advantages of blankets include: 2014 Stormwater Management Manual for Western Washington Volume II - Chapter 4 - Page 288 Attachment 10 - PLN20170047 Packet Pg. 159 2.1.a BMP C123: Plastic Covering Purpose Plastic covering provides immediate, short-term erosion protection to slopes and dis- turbed areas. Conditions of Use Plastic covering may be used on disturbed areas that require cover measures for less than 30 days, except as stated below. . 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 (greater than six months) applications. . Due to rapid runoff caused by plastic covering, do not use this method upslope of areas that might be adversely impacted by concentrated runoff. Such areas include steep and/or unstable slopes. . Plastic sheeting may result in increased runoff volumes and velocities, requiring additional on -site measures to counteract the increases. Creating a trough with wattles or other material can convey clean water away from these areas. . To prevent undercutting, trench and backfill rolled plastic covering products. . While plastic is inexpensive to purchase, the added cost of installation, main- tenance, removal, and disposal make this an expensive material, up to $1.50-2.00 per square yard. . Whenever plastic is used to protect slopes install water collection measures at the base of the slope. These measures include plastic -covered berms, channels, and pipes used to covey clean rainwater away from bare soil and disturbed areas. Do not mix clean runoff from a plastic covered slope with dirty runoff from a project. . Other uses for plastic include: 1. Temporary ditch liner. 2. Pond liner in temporary sediment pond. 3. Liner for bermed temporary fuel storage area if plastic is not reactive to the type of fuel being stored. 4. Emergency slope protection during heavy rains. 5. Temporary drainpipe ("elephant trunk") used to direct water. 2014 Stormwater Management Manual for Western Washington Volume 11- Chapter 4 - Page 294 Attachment 10 - PLN20170047 Packet Pg. 160 2.1.a Design and Installation Specifications . Plastic slope cover must be installed as follows: 1. Run plastic up and down slope, not across slope. 2. Plastic may be installed perpendicular to a slope if the slope length is less than 10 feet. 3. Minimum of 8-inch overlap at seams. 4. On long or wide slopes, or slopes subject to wind, tape all seams. 5. Place plastic into a small (12-inch wide by 6-inch deep) slot trench at the top of the slope and backfill with soil to keep water from flowing underneath. 6. Place sand filled burlap or geotextile bags every 3 to 6 feet along seams and tie them together with twine to hold them in place. 7. Inspect plastic for rips, tears, and open seams regularly and repair imme- diately. This prevents high velocity runoff from contacting bare soil which causes extreme erosion. 8. Sandbags may be lowered into place tied to ropes. However, all sandbags must be staked in place. • Plastic sheeting shall have a minimum thickness of 0.06 millimeters. . If erosion at the toe of a slope is likely, a gravel berm, riprap, or other suitable pro- tection shall be installed at the toe of the slope in order to reduce the velocity of run- off. Maintenance Standards . Torn sheets must be replaced and open seams repaired. . Completely remove and replace the plastic if it begins to deteriorate due to ultra- violet radiation. . Completely remove plastic when no longer needed. Dispose of old tires used to weight down plastic sheeting appropriately.

Conditions of Use In areas (including roadways) subject to surface and air movement of dust where on -site and off -site impacts to roadways, drainage ways, or surface waters are likely. Design and Installation Specifications . Vegetate or mulch areas that will not receive vehicle traffic. In areas where plant- ing, mulching, or paving is impractical, apply gravel or landscaping rock. . Limit dust generation by clearing only those areas where immediate activity will take place, leaving the remaining area(s) in the original condition. Maintain the ori- ginal ground cover as long as practical. . Construct natural or artificial windbreaks or windscreens. These may be designed as enclosures for small dust sources. . Sprinkle the site with water until surface is wet. Repeat as needed. To prevent carryout of mud onto street, refer to BMP C105: Stabilized Construction Entrance / Exit (p.270). . Irrigation water can be used for dust control. Irrigation systems should be installed as a first step on sites where dust control is a concern. . Spray exposed soil areas with a dust palliative, following the manufacturer's instructions and cautions regarding handling and application. Used oil is pro- hibited from use as a dust suppressant. Local governments may approve other dust palliatives such as calcium chloride or PAM. . PAM BMP C126: Poi ac lamide PAM for Soil Erosion Protection .300 ) added to water at a rate of 0.5 lbs. per 1,000 gallons of water per acre and applied from a water truck is more effective than water alone. This is due to increased infilt- ration of water into the soil and reduced evaporation. In addition, small soil particles are bonded together and are not as easily transported by wind. Adding PAM may actually reduce the quantity of water needed for dust control. Use of PAM could be a cost-effective dust control method. Techniques that can be used for unpaved roads and lots include: 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 310 Attachment 10 - PLN20170047 Packet Pg. 162 2.1.a Lower speed limits. High vehicle speed increases the amount of dust stirred up from unpaved roads and lots. Upgrade the road surface strength by improving particle size, shape, and mineral types that make up the surface and base materials. Add surface gravel to reduce the source of dust emission. Limit the amount of fine particles (those smaller than .075 mm) to 10 to 20 percent. Use geotextile fabrics to increase the strength of new roads or roads undergoing reconstruction. Encourage the use of alternate, paved routes, if available. . Restrict use of paved roadways by tracked vehicles and heavy trucks to prevent damage to road surface and base. . Apply chemical dust suppressants using the admix method, blending the product with the top few inches of surface material. Suppressants may also be applied as surface treatments. . Pave unpaved permanent roads and other trafficked areas. . Use vacuum street sweepers. . Remove mud and other dirt promptly so it does not dry and then turn into dust. e Limit dust -causing work on windy days. . Contact your local Air Pollution Control Authority for guidance and training on other dust control measures. Compliance with the local Air Pollution Control Authority constitutes compliance with this BMP. Maintenance Standards Respray area as necessary to keep dust to a minimum. BMP C150: Materials on Hand Purpose Keep quantities of erosion prevention and sediment control materials on the project site at all times to be used for regular maintenance and emergency situations such as unex- pected heavy summer rains. Having these materials on -site reduces the time needed to implement BMPs when inspections indicate that existing BMPs are not meeting the Con- struction SWPPP requirements. In addition, contractors can save money by buying some materials in bulk and storing them at their office or yard. 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 311 Attachment 10 - PLN20170047 Packet Pg. 163 2.1.a Conditions of Use Construction projects of any size or type can benefit from having materials on hand. A small commercial development project could have a roll of plastic and some gravel available for immediate protection of bare soil and temporary berm construction. A large earthwork project, such as highway construction, might have several tons of straw, several rolls of plastic, flexible pipe, sandbags, geotextile fab- ric and steel "T" posts. Materials are stockpiled and readily available before any site clearing, grubbing, or earthwork begins. A large contractor or developer could keep a stockpile of mater- ials that are available for use on several projects. If storage space at the project site is at a premium, the contractor could maintain the materials at their office or yard. The office or yard must be less than an hour from the project site. Design and Installation Specifications Depending on project type, size, complexity, and length, materials and quantities will vary. A good minimum list of items that will cover numerous situations includes: Material Clear Plastic, 6 mil Drainpipe, 6 or 8 inch diameter Sandbags, filled Straw Bales for mulching, Quarry Spalls 'Washed Gravel Geotextile Fabric Catch Basin Inserts Steel "T" Posts Silt fence material Straw Wattles Maintenance Standards All materials with the exception of the quarry spalls, steel "T" posts, and gravel should be kept covered and out of both sun and rain. . Re -stock materials used as needed. 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 312 Attachment 10 - PLN20170047 Packet Pg. 164 2.1.a BMP C151: Concrete Handling Purpose Concrete work can generate process water and slurry that contain fine particles and high pH, both of which can violate water quality standards in the receiving water. Concrete spillage or concrete discharge to surface waters of the State is prohibited.

Dispose of contained concrete in a manner that does not violate ground water or surface water quality standards. . Always use forms or solid barriers for concrete pours, such as pilings, within 15- feet of surface waters. . Refer to BMP C252: High pH Neutralization Using CO2 (p.4M and BMP C253: pH Control for High pH Water (p.412) for pH adjustment requirements. Refer to the Construction Stormwater General Permit for pH monitoring require- ments if the project involves one of the following activities: . Significant concrete work (greater than 1,000 cubic yards poured concrete or recycled concrete used over the life of a project). . The use of engineered soils amended with (but not limited to) Portland cement -treated base, cement kiln dust or fly ash. . Discharging stormwater to segments of water bodies on the 303(d) list (Cat- egory 5) for high pH. Maintenance Standards Check containers for holes in the liner daily during concrete pours and repair the same day. SNIP C152: Sawcutting and Surfacing Pollution Prevention Purpose Sawcutting and surfacing operations generate slurry and process water that contains fine particles and high pH (concrete cutting), both of which can violate the water quality standards in the receiving water. Concrete spillage or concrete discharge to surface waters of the State is prohibited. Use this BMP to minimize and eliminate process water and slurry created through sawcutting or surfacing from entering waters of the State. Conditions of Use Utilize these management practices anytime sawcutting or surfacing operations take place. Sawcutting and surfacing operations include, but are not limited to, the following: . Sawing . Coring . Grinding . Roughening 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 314 Attachment 10 - PLN20170047 Packet Pg. 166 2.1.a . Hydro -demolition Bridge and road surfacing Design and Installation Specifications . Vacuum slurry and cuttings during cutting and surfacing operations. Slurry and cuttings shall not remain on permanent concrete or asphalt pavement overnight. . Slurry and cuttings shall not drain to any natural or constructed drainage con- veyance including stormwater systems. This may require temporarily blocking catch basins. • Dispose of collected slurry and cuttings in a manner that does not violate ground water or surface water quality standards. • Do not allow process water generated during hydro -demolition, surface rough- ening or similar operations to drain to any natural or constructed drainage con- veyance including stormwater systems. Dispose process water in a manner that does not violate ground water or surface water quality standards. Handle and dispose cleaning waste material and demolition debris in a manner that does not cause contamination of water. Dispose of sweeping material from a pick-up sweeper at an appropriate disposal site. Maintenance Standards Continually monitor operations to determine whether slurry, cuttings, or process water could enter waters of the state. If inspections show that a violation of water quality stand- ards could occur, stop operations and immediately implement preventive measures such as berms, barriers, secondary containment, and vacuum trucks. BMP C153: Material Delivery, Storage and Containment Purpose Prevent, reduce, or eliminate the discharge of pollutants to the stormwater system or watercourses from material delivery and storage. Minimize the storage of hazardous materials on -site, store materials in a designated area, and install secondary con- tainment. Conditions of Use These procedures are suitable for use at all construction sites with delivery and storage of the following materials: 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 315 Attachment 10 - PLN20170047 Packet Pg. 167 2.1.a . Petroleum products such as fuel, oil and grease . Soil stabilizers and binders (e.g., Polyacrylamide) Fertilizers, pesticides and herbicides Detergents Asphalt and concrete compounds . Hazardous chemicals such as acids, lime, adhesives, paints, solvents, and curing compounds . Any other material that may be detrimental if released to the environment Design and Installation Specifications The following steps should be taken to minimize risk: . Temporary storage area should be located away from vehicular traffic, near the con- struction entrance(s), and away from waterways or storm drains. Material Safety Data Sheets (MSDS) should be supplied for all materials stored. Chemicals should be kept in their original labeled containers. . Hazardous material storage on -site should be minimized. . Hazardous materials should be handled as infrequently as possible. During the wet weather season (Oct 1 — April 30), consider storing materials in a covered area. . Materials should be stored in secondary containments, such as earthen dike, horse trough, or even a children's wading pool for non -reactive materials such as deter- gents, oil, grease, and paints. Small amounts of material may be secondarily con- tained in "bus boy" trays or concrete mixing trays. Do not store chemicals, drums, or bagged materials directly on the ground. Place these items on a pallet and, when possible, and within secondary containment. . If drums must be kept uncovered, store them at a slight angle to reduce ponding of rainwater on the lids to reduce corrosion. Domed plastic covers are inexpensive and snap to the top of drums, preventing water from collecting. Material Storage Areas and Secondary Containment Practices: • Liquids, petroleum products, and substances listed in 40 CFR Parts 110, 117, or 302 shall be stored in approved containers and drums and shall not be overfilled. Containers and drums shall be stored in temporary secondary containment facil- ities. • Temporary secondary containment facilities shall provide for a spill containment 2014 Stormwater Management Manual for Western Washington Volume 11- Chapter 4 - Page 316 Attachment 10 - PLN20170047 Packet Pg. 168 2.1.a volume able to contain 10% of the total enclosed container volume of all con- tainers, or 110% of the capacity of the largest container within its boundary, whichever is greater. Secondary containment facilities shall be impervious to the materials stored therein for a minimum contact time of 72 hours. Secondary containment facilities shall be maintained free of accumulated rain- water and spills. In the event of spills or leaks, accumulated rainwater and spills shall be collected and placed into drums. These liquids shall be handled as haz- ardous waste unless testing determines them to be non -hazardous. Sufficient separation should be provided between stored containers to allow for spill cleanup and emergency response access. During the wet weather season (Oct 1 — April 30), each secondary containment facility shall be covered during non -working days, prior to and during rain events. Keep material storage areas clean, organized and equipped with an ample supply of appropriate spill clean-up material (spill kit). The spill kit should include, at a minimum: 1-Water Resistant Nylon Bag 3-Oil Absorbent Socks 3" x 4' 2-Oil Absorbent Socks 3"x 10' 12-Oil Absorbent Pads 17"x19" 1-Pair Splash Resistant Goggles 3-Pair Nitrile Gloves 10-Disposable Bags with Ties Instructions BMP C154: Concrete Washout Area Purpose Prevent or reduce the discharge of pollutants to stormwater from concrete waste by con- ducting washout off -site, or performing on -site washout in a designated area to prevent pollutants from entering surface waters or ground water. Conditions of Use Concrete washout area best management practices are implemented on construction projects where: 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 317 Attachment 10 - PLN20170047 Packet Pg. 169 2.1.a BMP C160: Certified Erosion and Sediment Control Lead Purpose The project proponent designates at least one person as the responsible representative in charge of erosion and sediment control (ESC), and water quality protection. The des- ignated person shall be the Certified Erosion and Sediment Control Lead (CESCL) who is responsible for ensuring compliance with all local, state, and federal erosion and sed- iment control and water quality requirements. Conditions of Use A CESCL shall be made available on projects one acre or larger that discharge storm - water to surface waters of the state. Sites less than one acre may have a person without CESCL certification conduct inspections; sampling is not required on sites that disturb less than an acre. . The CESCL shall: Have a current certificate proving attendance in an erosion and sediment con- trol training course that meets the minimum ESC training and certification requirements established by Ecology (see details below). Ecology will maintain a list of ESC training and certification providers at: hftp://www.ecy.wa.9ov/programstwq/stormwater/cescl.html OR . Be a Certified Professional in Erosion and Sediment Control (CPESC); for additional information go to: http://www.enyirocertintl.org/cpesc/ Specifications . Certification shall remain valid for three years. . The CESCL shall have authority to act on behalf of the contractor or developer and shall be available, or on -call, 24 hours per day throughout the period of con- struction. The Construction SWPPP shall include the name, telephone number, fax number, and address of the designated CESCL. A CESCL may provide inspection and compliance services for multiple con- struction projects in the same geographic region. Duties and responsibilities of the CESCL shall include, but are not limited to the fol- lowing: 2014 Stormwater Management Manual for Western Washington Volume Il - Chapter 4 - Page 325 Attachment 10 - PLN20170047 Packet Pg. 170 2.1.a Maintaining permit file on site at all times which includes the Construction SWPPP and any associated permits and plans. Directing BMP installation, inspection, maintenance, modification, and removal. . Updating all project drawings and the Construction SWPPP with changes made. Completing any sampling requirements including reporting results using WebDMR. • Keeping daily logs, and inspection reports. Inspection reports should include: . Inspection date/time. Weather information; general conditions during inspection and approximate amount of precipitation since the last inspection. . A summary or list of all BMPs implemented, including observations of all erosion/sediment control structures or practices. The following shall be noted: 1. Locations of BMPs inspected. 2. Locations of BMPs that need maintenance. 3. Locations of BMPs that failed to operate as designed or intended. 4. Locations of where additional or different BMPs are required. • Visual monitoring results, including a description of discharged stormwater. The presence of suspended sediment, turbid water, discoloration, and oil sheen shall be noted, as applicable. . Any water quality monitoring performed during inspection. . General comments and notes, including a brief description of any BMP repairs, maintenance or installations made as a result of the inspection. • Facilitate, participate in, and take corrective actions resulting from inspections per- formed by outside agencies or the owner. BMP C162: Scheduling Purpose Sequencing a construction project reduces the amount and duration of soil exposed to erosion by wind, rain, runoff, and vehicle tracking. Conditions of Use The construction sequence schedule is an orderly listing of all major land -disturbing activities together with the necessary erosion and sedimentation control measures 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 326 Attachment 10 - PLN20170047 Packet Pg. 171 2.1.a planned for the project. This type of schedule guides the contractor on work to be done before other work is started so that serious erosion and sedimentation problems can be avoided. Following a specified work schedule that coordinates the timing of land -disturbing activ- ities and the installation of control measures is perhaps the most cost-effective way of controlling erosion during construction. The removal of surface ground cover leaves a site vulnerable to accelerated erosion. Construction procedures that limit land clearing provide timely installation of erosion and sedimentation controls, and restore protective cover quickly can significantly reduce the erosion potential of a site. Design Considerations Minimize construction during rainy periods. Schedule projects to disturb only small portions of the site at any one time. Com- plete grading as soon as possible. Immediately stabilize the disturbed portion before grading the next portion. Practice staged seeding in order to revegetate cut and fill slopes as the work progresses. 11-4.2 Runoff Conveyance and Treatment BMPs This section contains the standards and specifications for Runoff Conveyance and Treat- ment BMPs.

The maximum spacing between the dams shall be such that the toe of the upstream dam is at the same elevation as the top of the downstream dam. . Keep the maximum height at 2 feet at the center of the dam. b Keep the center of the check dam at least 12 inches lower than the outer edges at natural ground elevation. Keep the side slopes of the check dam at 2H:1 V or flatter. Key the stone into the ditch banks and extend it beyond the abutments a minimum of 18 inches to avoid washouts from overflow around the dam. Use filter fabric foundation under a rock or sand bag check dam. If a blanket ditch liner is used, filter fabric is not necessary. A piece of organic or synthetic blanket cut to fit will also work for this purpose. In the case of grass -lined ditches and swales, all 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 check dams shall be seeded and mulched immediately after dam removal. . Ensure that channel appurtenances, such as culvert entrances below check dams, are not subject to damage or blockage from displaced stones. F4ure II-4.2.7 Rock Check Dam (p.354) depicts a typical rock check dam. Maintenance Standards Check dams shall be monitored for performance and sediment accumulation during and after each runoff producing rainfall. Sediment shall be removed when it reaches one half the sump depth. o Anticipate submergence and deposition above the check dam and erosion from high flows around the edges of the dam. If significant erosion occurs between dams, install a protective riprap liner in that portion of the channel.

Conditions of Use . Maybe used on soil or pavement with adhesive or staples. . TSDs have been used to build temporary: 1. sediment ponds; 2. diversion ditches; 3. concrete wash out facilities; 4. curbing; 5. water bars; 6. level spreaders; and, 7. berms. Design and Installation Specifications Made of urethane foam sewn into a woven geosynthetic fabric. It is 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. . Install with ends curved up to prevent water from flowing around the ends. . The fabric flaps and check dam units are attached to the ground with wire staples. Wire staples should be No. 11 gauge wire and should be 200 mm to 300 mm in length. . When multiple units are installed, the sleeve of fabric at the end of the unit shall overlap the abutting unit and be stapled. . Check dams should be located and installed as soon as construction will allow. . Check dams should be placed perpendicular to the flow of water. . When used as check dams, the leading edge must be secured with rocks, sand- bags, or a small key slot and staples. 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 355 Attachment 10 - PLN20170047 Packet Pg. 177 2.1.a In the case of grass -lined ditches and swales, check dams and accumulated sed- iment 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 check dams shall be seeded and mulched immediately after dam removal. Maintenance Standards . Triangular silt dams shall be inspected for performance and sediment accu- mulation during and after each runoff producing rainfall. Sediment shall be removed when it reaches one half the height of the dam. Anticipate submergence and deposition above the triangular silt dam and erosion from high flows around the edges of the dam. Immediately repair any damage or any undercutting of the dam. BMP C209: Outlet Protection Purpose Outlet protection prevents scour at conveyance outlets and minimizes the potential for downstream erosion by reducing the velocity of concentrated stormwater flows. Conditions of Use Outlet protection is required at the outlets of all ponds, pipes, ditches, or other con- veyances, and where runoff is conveyed to a natural or manmade drainage feature such as a stream, wetland, lake, or ditch. Design and Installation Specifications The receiving channel at the outlet of a culvert shall be protected from erosion by rock lin- ing a minimum of 6 feet downstream and extending up the channel sides a minimum of 1—foot above the maximum tailwater elevation or 1-foot above the crown, whichever is higher. For large pipes (more than 18 inches in diameter), the outlet protection lining of the channel is lengthened to four times the diameter of the culvert. . Standard wingwalls, and tapered outlets and paved channels should also be con- sidered when appropriate for permanent culvert outlet protection. (See WSDOT Hydraulic Manual, available through WSDOT Engineering Publications). . Organic or synthetic erosion blankets, with or without vegetation, are usually more effective than rock, cheaper, and easier to install. Materials can be chosen using manufacturer product specifications. ASTM test results are available for most products and the designer can choose the correct material for the expected flow. . With low flows, vegetation (including sod) can be effective. . The following guidelines shall be used for riprap outlet protection: 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 356 Attachment 10 - PLN20170047 Packet Pg. 178 2.1.a 1. If the discharge velocity at the outlet is less than 5 fps (pipe slope less than 1 percent), use 2-inch to 8-inch riprap. Minimum thickness is 1-foot. 2. For 5 to 10 fps discharge velocity at the outlet (pipe slope less than 3 per- cent), use 24-inch to 48-inch riprap. Minimum thickness is 2 feet. 3. For outlets at the base of steep slope pipes (pipe slope greater than 10 per- cent), an engineered energy dissipater shall be used. . Filter fabric or erosion control blankets should always be used under riprap to pre- vent scour and channel erosion. New pipe outfalls can provide an opportunity for low-cost fish habitat improve- ments. For example, an alcove of low -velocity water can be created by con- structing the pipe outfall and associated energy dissipater back from the stream edge and digging a channel, over -widened to the upstream side, from the outfall. Overwintering juvenile and migrating adult salmonids may use the alcove as shel- ter during high flows. Bank stabilization, bioengineering, and habitat features may be required fot' disturbed areas. This work may require a HPA. See Volume V ip 765) for more information on outfall system design. Maintenance Standards a Inspect and repair as needed. . Add rock as needed to maintain the intended function. . Clean energy dissipater if sediment builds up. BMP C220: Storm Drain Inlet Protection Purpose Storm drain inlet protection prevents coarse sediment from entering drainage systems prior to permanent stabilization of the disturbed area. Conditions of Use Use storm drain inlet protection at inlets that are operational before permanent sta- bilization of the disturbed drainage area. Provide protection for all storm drain inlets downslope and within 500 feet of a disturbed or construction area, unless conveying run- off entering catch basins to a sediment pond or trap. Also consider inlet protection for lawn and yard drains on new home construction. These small and numerous drains coupled with lack of gutters in new home construction can add significant amounts of sediment into the roof drain system. If possible delay installing lawn and yard drains until just before landscaping or cap these drains to pre- 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 357 Attachment 10 - PLN20170047 Packet Pg. 179 2.1.a vent sediment from entering the system until completion of landscaping. Provide 18- inches of sod around each finished lawn and yard drain. Table II-4.2.2 Storm Drain Inlet Protection (.358) lists several options for inlet protection. All of the methods for storm drain inlet protection tend to plug and require a high fre- quency of maintenance. Limit drainage areas to one acre or less. Possibly provide emer- gency overflows with additional end -of -pipe treatment where stormwater ponding would cause a hazard.

This struc- ture does not provide an overflow. Use a hardware cloth or comparable wire mesh with Y2-inch openings. . Use coarse aggregate. . Provide a height 1-foot or more, 18-inches wider than inlet on all sides. . Place wire mesh over the drop inlet so that the wire extends a minimum of 1-foot beyond each side of the inlet structure. Overlap the strips if more than one strip of mesh is necessary. . Place coarse aggregate over the wire mesh. . Provide at least a 12-inch depth of gravel over the entire inlet opening and extend at least 18-inches on all sides. Catchbasin Filters — Use inserts designed by manufacturers for construction sites. The limited sediment storage capacity increases the amount of inspection and maintenance required, which may be daily for heavy sediment loads. To reduce maintenance require- ments combine a catchbasin filter with another type of inlet protection. This type of inlet protection provides flow bypass without overflow and therefore may be a better method for inlets located along active rights -of -way. . Provides 5 cubic feet of storage. . Requires dewatering provisions. . Provides a high -flow bypass that will not clog under normal use at a construction site. • Insert the catchbasin filter in the catchbasin just below the grating. Curb Inlet Protection with Wooden Weir— Barrier formed around a curb inlet with a wooden frame and gravel. . Use wire mesh with 1/2-inch openings. . Use extra strength filter cloth. . Construct a frame. . Attach the wire and filter fabric to the frame. . Pile coarse washed aggregate against wire/fabric. • Place weight on frame anchors. Block and Gravel Curb Inlet Protection — Barrier formed around a curb inlet with concrete blocks and gravel. See Figure II-4.2.9 Block and Gravel Curb Inlet Protection .363 . 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 361 Attachment 10 - PLN20170047 Packet Pg. 183 2.1.a . Use wire mesh with'/2-inch openings. . Place two concrete blocks on their sides abutting the curb at either side of the inlet opening. These are spacer blocks. . Place a 2x4 stud through the outer holes of each spacer block to align the front blocks. . Place blocks on their sides across the front of the inlet and abutting the spacer blocks. . Place wire mesh over the outside vertical face. . Pile coarse aggregate against the wire to the top of the barrier. Curb and Gutter Sediment Barrier— Sandbag or rock berm (riprap and aggregate) 3 feet high and 3 feet wide in a horseshoe shape. See Figure II-4.2.10 Curb and Gutter Barrier (p 364). . Construct a horseshoe shaped berm, faced with coarse aggregate if using riprap, 3 feet high and 3 feet wide, at least 2 feet from the inlet. . Construct a horseshoe shaped sedimentation trap on the outside of the berm sized to sediment trap standards for protecting a culvert inlet. Maintenance Standards . Inspect catch basin filters frequently, especially after storm events. Clean and replace clogged inserts. For systems with clogged stone filters: pull away the stones from the inlet and clean or replace. An alternative approach would be to use the clogged stone as fill and put fresh stone around the inlet. . Do not wash sediment into storm drains while cleaning. Spread all excavated material evenly over the surrounding land area or stockpile and stabilize as appro- priate.

Conditions of Use Where a temporary measure is needed to retain sediment from rights -of -way or in traffic areas on construction sites. Design and Installation Specifications Berm material shall be 3/ to 3 inches in size, washed well -grade gravel or crushed rock with less than 5 percent fines. . Spacing of berms: Every 300 feet on slopes less than 5 percent Every 200 feet on slopes between 5 percent and 10 percent Every 100 feet on slopes greater than 10 percent Berm dimensions: 1 foot high with 3H:1V side slopes 8 linear feet per 1 cfs runoff based on the 10-year, 24-hour design storm Maintenance Standards Regular inspection is required. Sediment shall be removed and filter material replaced as needed. BMP C233: 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. See Figure II-4.2.12 Silt Fence_( for details on silt fence con- struction. Conditions of Use Silt fence may be used downslope of all disturbed areas. 2014 Stormwater Management Manual for Western Washington Volume 11 - Chapter 4 - Page 367 Attachment 10 - PLN20170047 Packet Pg. 187 2.1.a Silt fence shall prevent soil carried by runoff water from going beneath, through, or over the top of the silt fence, but shall allow the water to pass through the fence. Silt fence is not intended to treat concentrated flows, nor is it intended to treat sub- stantial amounts of overland flow. Convey any concentrated flows through the drainage system to a sediment pond. . Do not construct silt fences in streams or use in V-shaped ditches. Silt fences do not provide an adequate method of silt control for anything deeper than sheet or overland flow. 2014 Stormwater Management Manual for Western Washington Volume II - Chapter 4 - Page 368 Attachment 10 - PLN20170047 Packet Pg. 188 2.1.a C.

Tbese, methods are discussed below. Storage and Reuse Roof runoff may be stored in cisterns or barrels during rainstorms. Water stored may be used later for watering plants and irrigating lawns. Splash Blocks The proposed residences are of limited total impervious area. Therefore, using Splash blocks under roof downspouts to spread roof ninoff onto grass covered yards would be sufficient to dispose roof runoff. Downspouts should be extended to at least 6 feet away from the structures where splash blocks are placed to create sheet flow onto the yards. The yards should be re -graded as necessary to allow disposed stormwater to iflow away from the townhornes. Infiltration Trenches The project site is underlain at shallow depth by a very -dense, cemented, glacial till deposit of extremely low permeability. Therefore, using infiltration trenches or rain gardens to dispose stormwater solely by infiltration would require a large infiltration bottom area, will be inefficient and may not work well. If used, infiltration trenches LIU & ASSOCIATES, INC.

Because the SWMMWW does not always include clear itemization of project procedural and/or submittal requirements, the City of Edmonds developed Appendix B of this Addendum (Methods for Determining Design Infiltration Rates) as well as this accompanying checklist to aid project proponents and plan reviewers in complying with the applicable S WMM W W requirements. In addition, City -specific requirements (i.e., requirements presented in ECDC 18.30 and the Addendum that are not included in the SV1N MWW) are also included in the appendix and checklist. This checklist reflects most, but not necessarily all, of the items that shall be performed by the project proponent, and documented for review by the Engineering Division. It is intended to be used as an aid for developers and plan reviewers by providing a foundation for clear and consistent infiltration evaluation processes in the City of Edmonds.

Falling Bead Percolation Test Procedure (as Modified for the City of Edmonds; for performance verification only) Space tests uniformly throughout the area. If soil conditions are highly variable, more tests may be required. Pre aration of Test Hole 4 The diameter of each test hole is 8 inches. The depth of each test is to the proposed depths of the absorption systems or to the most limiting soil horizon. To expose a natural soii surface, scratch the bottom of the hole with a sharp pointed instrument and remove the loose material from the test hole. Set a PVC pipe (6 inch -inner -diameter, 4 foot long) into the hole and press into the soil 6 inches. 1 f Place 2 inches of 0.5- to 0.75-inch rock in the pipe to protect the bottom from scouring when water is added. Soaking Period In sandy soils with little or no clay, soaking is not necessary (proceed to Measurement of the Percolation [lace). Carefully fill the pipe with at least 12 inches of clear water. Maintain the depth of water for at least 4 hours (and preferably overnight if clay soils are present). If, after filling the pipe twice with 12 inches of water, the water seeps completely away in less than 10 minutes, the test can proceed immediately (proceed to Measurement of the Percolation Rate).

Adjust the water level to 6 inches above the gravel (or S inches above the bottom of the F?i hole). At no time during the test is the water level allowed to rise more than 6 inches above the gravel, Immediately after adjustment, measure the water level from a fixed reference point to the nearest l/ 16th inch at 30-minute intervals. Continue the test until two successive water level drops do not vary by more than 1 /16 inch within a 90-minute period. At least three measurements are to be made. After each measurement, readjust the water level to the 6-inch level. Use the last water level drop to calculate the percolation rate. In sandy soils or soils in which the first 6 inches of water added after the soaking period seeps away in less than 30 minutes, make water level measurements at 10-minute intervals for a 1-hour period. Use the last water level drop to calculate the percolation rate. Calculate the Design Infiltration Rate Calculate the percolation rate for each test site by dividing the time interval used between measurements by the magnitude of the last water level drop. This calculation results in a .; $ percolation rate in minutes/inch. To determine the percolation rate for the area, average the rates obtained from each hole. (If tests in the area vary by more than 20 minutes/inch, variations in soil type are indicated. Under these circumstances, percolation rates should not be averaged.) ;BHP j To compute the design infiltration rate (Ksatae,;�,), adjust the final percolation rates by the 1V appropriate correction factors outlined above. Method 3 — Soil Grain Analysis (SWMMWW Volume III, Section 3.3.6) For infiltration basins and trenches, perform the grain size analysis for each defined layer 53 below the infiltration facility to a depth below the facility bottom of 2.5 times the maximum depth of water in the pond, but not less than 10 feet. For large infiltration facilities serving drainage areas of 10 acres or more, soil grain size 3 analyses are performed on layers up to 50 feet deep (or no more than 10 feet below the water table). For bioretention areas, each defined layer is analyzed below the top of the final bioretention j area subgrade to a depth of at least 3 times the maximum ponding depth, but not less than 3 feet (1 meter). For permeable pavement, each defined layer is analyzed below the top of the final subgrade— :>; to a depth of at least 3 times the maximum ponding depth within the base (reservoir) course, but not less than 3 feet (I meter). If the licensed professional conducting the investigation determines that deeper layers will influence the rate of infiltration for the facility, soil layers at greater depths may be considered when assessing the site's hydraulic conductivity characteristics.

Zack Richardson, P.E., Stormwater Engineer 121 5th Ave N Edmonds, WA 98020 Re: 244th St. Townhomes — BLD20171333 IECO No. 16-0800 Dear Mr. Richardson, March 5, 2018 APR 20 2010 DEVELORMT SEfli010ES COUWFFt The project referenced above is revised in response to the review comments dated November 20, 2017. The review comments are numbered on the letter and have been addressed in italics as follows: Review Comments: 1. Geotechnical Report: It is not clear what testing method was used to determine the design infiltration rate or that the design infiltration rate includes the correct adjustment factors. Update report to include more thorough description of infiltration testing and ensure design rate calculations are consistent with City of Edmonds SWMMWW Addendum Checklist #4. Refer to the latest geotechnical report completed by Liu & Associates, Inc. dated 312112018 included in the appendix of the revised drainage report. a. It is also unclear how the engineer determined varied rates for different BMP types; provide calculations to support each rate provided or remove non -pertinent rates. Refer to the latest geotechnical report completed by Liu & Associates, Inc. dated 312112018 included in the appendix of the revised drainage report. 2. Drainage Report: It is unclear why the designer omitted all pervious areas from the hydrologic modelling; update modelling to reflect entire site or provide clarification as needed. PO Box 1478 • Everett, WA 98206 • Phone: (425) 303-9363 Fax: (425) 303-9362 • Email:info@insightengineering.net Attachment 16 - PLN20170047 Packet Pg. 238 2.1.a a. If areas are to by-pass the infiltration facility, the calculations must be updated to demonstrate that the flow control and LID requirements are met at a downstream point of compliance which considers the by-pass flows. No by-pass areas are contained within the site. 3. Drainage Report: It is unclear why the modelled 0.66 acres was further reduces to 0.44 areas for the mitigated W WHM run (page 4 of W WHM report); update or provide clarification as needed. The pavement contains a surface area of 9,792 SF (0.22 Acres), this area is accounted for within the permeable pavement element. Therefore, it was taken out of the developed basin. The total developed basin = perm pav area + remainder of site. 4. Drainage Report: Engineer shall provide explanations of how the void ratios of each material were selected for the WWHM model. a. Pre SWMMWW, porous asphalts are typically 16% - 25% (page 929) b. The 0.4 value used for the rock layer is typical of rounded (Type 26) rock; crushed rock would typically be assumed to have less void space than rounded rock. The void ratios within the WWHM model have been adjusted accordingly. Drainage Report: It appears that the engineer included both rock layers in the storage volume of the pervious pavement facility; typically the structural or choker course are not included in this volume. Engineer shall update text of report to address potential impacts for planning on stored water within this course layer (or update design to only utilize lower storage course). The choker course has been removed from the calculation. 6. Drainage Report: The modelled slope of the pervious pavement doers not appear to match the plan sheet; update calculations as needed. a. Note that check damns are required for slopes exceeding 3% which may further reduce capacity of the system; update plans and calculations. Refer to note #6 within the Permeable Asphalt Notes on sheet C3.0. 7. C2.0: The SWPPP notes a sediment trap/pond in several locations which is not currently shown on the plans; show sediment trap/pond and sizing calculation or revise SWPPP for consistency. a. If pond trap is not provided, expand drainage report to explain why engineer believes no flow control is needed and why silt fence, alone, is anticipated to be sufficient for sediment control. PO Box 1478 • Everett, WA 98206 • Phone: (425) 303-9363 Fax: (425) 303-9362 • Email:info@insightengineering.net Attachment 16 - PLN20170047 Packet Pg. 239 2.1.a A sediment trap has been shown on sheet C2.0. C2.0: It is unclear how the infiltration areas will be protected or sequenced during construction; update plans and notes as needed to provide direction to contractor to ensure adequate infiltration capabilities at end of construction. a. Since soil remediation is required and will remove the top 2' from the site, it is recommended that over excavation of the driveway areas and soil remediation work occur at the very tail end of the construction process. Refer to Element #13 of the 12 Elements of TESC BMP on sheet C2.0. 9. C2.0: It appears that there is no proposed control for runoff from pervious areas; address runoff from pervious areas or update drainage report to address impacts of drainage to adjacent parcel from these areas (and remove all statement of "no discharge from the site"). Interceptor swales are now proposed and will be directed to the sediment trap. 10. C3.0: Include or reference a dispersion trench detail as needed for construction of the facility. A cross-section detail of the dispersion trench has been referenced and has been added to sheet C5.1. 11. C3.0: Utilities installed within or under infiltration facilities must include trench check - damns to prevent the horizontal movement of runoff along the pipe trenches; update plans and provide details as needed. (Also recommended in the "infiltration trenches" part of the geotechnical report). Refer to note 12 on sheet C3.0. A Check Dam detail has been added to sheet C5.1. The geotechnical report has been updated accordingly. 12. C3.0: It is unclear what is proposed for discharge of the footing drains; update plans as needed to show how footing drains will outlet. a. If discharging to the infiltration system, provide elevations sufficient to verify that footing drains will not be backwatered by the infiltration facility. The footing drains for each home will be connected to the corresponding yard drain. The yard drain elevations have been list in the "Storm Yard Drain" table on sheet C3.0. 13. C3.0: It appears from the information provided, that the yard drain outlet pipes do not have the minimum 2' cover required under traffic rates surfaces; update to provide adequate cover and/or provide additional info to demonstrate adequate pipe strength (manufacturers spec, geotechnical evaluation, etc.).

Per manufactures requirements, only I' of cover is required. Refer to the appendix of the drainage report for the Technical Note from ADS for the HDPE pipe. 14. C3.0: Update permeable asphalt section to reference note #4 (instead of note #5) for soils information. The permeable asphalt section has new referenced note #4. 15. C3.0: Provide full specification for contractor to meet the soil water quality treatment requirement (spec particular product type, mixing ratio, etc.); current direction is too vague to ensure organic content/cat-ion exchange rate is achieved. Specification based on the geotechnical recommendation has been added. Refer to note #4 within the permeable pavement notes. 16. C3.1: As noted in checklist #11, check damns are required for pervious pavement slopes exceeding 3%; update plans to provide check damns and details as needed. Refer to detail 7 on sheet C4.0 17. C3.1: The proposed low spot of Road A does not align with the crossing flow line of Road B; update plans as needed and/or provide additional spot elevations on the grading plan for all "non -typical" areas of grading/sloping. The low point along Road -A has been revised to be located at the intersection of Road-B. Refer to the revised profile for Road A on sheet C3.1. 18. C3.1: It appears the outlet pipe from CB #1 does not have the minimum 2' cover required under traffic rates surfaces; update to provide adequate cover and/or provide addition info to demonstrate adequate pipe strength (manufacturers spec, geotechnical evaluation, etc.). The minimum 2' of cover has now been proposed. Please feel free to contact me with any questions or comments you may have. Sincerely, /ZZ/ an Kalab, P.E.

Review Comments: 1. It is not clear that infiltration can function as proposed due to invert elevation constraints. In generally appears that the top of ponded surface (ie. top of storage rock) is above the invert elevations of the adjacent yard drains; therefore it is not clear that the roof or footing runoff can achieve positive flow into the system without backwatering. Update and or address as needed. a. Roof (solid) drains may still function with backwatered yard drains as long as positive flow is achieved with the piping but additional information is needed. b. Footing (perforated) drain pipes cannot be backwatered at all. 2. It is not clear that the impacts of utility trenches are adequately addressed and will not impact the storm design proposal. It appears the water line has between 3 and 3.5 feet of cover which would align it directly within the pervious pavement section shown and reduces the capacity of the system (either to storage capacity or treatment capacity depending on exact elevations); update plan or address potential impacts to the storm drain function as a result. 3. It is not clear that infiltration is feasible due to depth of impervious layer. It appears that the pervious pavement section (with treatment layer) is 42" deep and the till layer was identified at 39", 48", and 57" and therefore it does not Attachment 19 - PLN20170047 Packet Pg. 255 2.1.a appear that adequate separation is maintained to the impervious layer. Update and or address as needed. a. Note that the plate 2 of the submitted geotechnical report does not show IT-3 or include any IT-3 information despite being referenced in the text pertaining to the infiltration test; update or include as needed. Prior Construction Approval: The following comments were noted by the reviewer as issues that will likely require revision prior to construction approval, but do not necessarily required attention prior to feasibility approval. A. Specify edge treatments around permeable pavement (COE detail SD-625 & SD- 626). B. Additional protections for utilities lines near and within the infiltration section will be needed: a. Additional 'collar' or'flow-stop' type check -dams will be needed for utility penetrations within the pervious pavement; these are slightly larger than the utility trench section in order to completely stop flow in the trench. b. Any utilities below the infiltration surface which are within 5' feet, horizontal or vertical, of the infiltration limits must be protected from infiltration water; include impervious liners on top or side of trenches as needed. C. Show location and or spacing of all check damns. D. Ensure slope of road is accurately reflected in modelling (road slope is currently 2.99% but only modelled at 2.0%).
