DNS BLD2021-1482+SWPPP+11.3.2021_10.40.54_AM+2499280Stormwater Pollution Prevention Plan (SWPPP) Short Form For Small and Medium Construction Projects Introduction A Stormwater Pollution Prevention Plan (SWPPP) is a document that explains the potential for stormwater pollution caused by construction activities and the methods required to control those problems. With properly planned, installed and maintained Best Management Practices (BMPs), stormwater impacts such as heavy stormwater flows, soil erosion, and degradation of water quality can be minimized. All projects of any size must manage the stormwater runoff from construction sites, demolition, clearing and grading projects, or other activity that exposes soils. This guide page describes the main parts of a SWPPP for Small and Medium Impact projects, which include: • The SWPPP Short Form (this form), and • The applicable BMP details (located at the end of this form), and • An Erosion and Sediment Control (ESC) plan. The purpose of the SWPPP is to outline the actions that will be implemented on construction sites to reduce or eliminate discharge of sediment and other pollutants into receiving waters. Completing this checklist will ensure a well -prepared plan that meets City of Renton standards. Managing construction stormwater runoff and pollution on project sites is required by the Western Washington Phase II Municipal Stormwater Permit issued to the City of Shoreline by the Washington State Department of Ecology. Eligibility and Requirements The SWPPP Short Form is required for all Small and Medium Impact Projects. This includes any project that: • Disturbs up to 7,000 square feet of land, or • Creates less than 5,000 square feet of hard surface, or Grades/fills less than 500 cubic yards. 2/2019 Stormwater Pollution Prevention Plan (SWPPP) Short Form For Small and Medium Construction Projects Site Inspections Projects that disturb one or more acres must have site inspections conducted by a Certified Erosion and Sediment Control Lead (CESCL). Project sites less than one -acre (not part of a larger common plan of development or sale) may have a person without Certified Erosion and Sediment Control Lead (CESCL) certification conduct the site inspections. The CESCL or inspector must have the skills to assess the: • Site conditions and construction activities that could impact the quality of stormwater. • Effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges. The CESCL or inspector must inspect all areas disturbed by construction activities, all BMPs, and all stormwater discharges at least once every calendar week and within 24 hours of any discharge from the site. The CESCL or inspector must examine stormwater visually for the presence of suspended sediment, turbidity, discoloration, and oil sheen. The CESCL or inspector must complete the Site Inspection Form and attach all completed SWPPP Site Inspection Forms to the SWPPP for reporting and recordkeeping. 2/2019 Stormwater Pollution Prevention Plan (SWPPP) Short Form For Small and Medium Construction Projects Section 1: Background Information Project Title: Burdett SFR Site Address: 332 Sunset Ave N.

If site conditions render an element unnecessary, check "other" and briefly describe why it is not needed. 1. Mark Clearing Limits — Prior to beginning land disturbing activities, all projects must visibly mark clearing limits, critical areas and their buffers, and any trees to be preserved. Clearly mark limits both in the field and on the plans. Do not staple or wire fences to trees. Applicable BMPs include: ❑Preserve existing vegetation — BMP C101 ❑High Visibility Plastic or Metal Fence — BMP C103 *Tree Protection During Construction — BMP T101 *Other: Silt fence BMP C233 2. Establish Construction Access — All construction projects subject to vehicular traffic shall provide a means of preventing vehicle tracking of soil from the site onto City streets. At a minimum, access to the site shall be stabilized with a quarry spall pad, or other equivalent BMP, to minimize tracking sediment into the roadway. If the existing paved access to the site is used as the construction access, it must be clearly labeled on the plans. If sediment is tracked off -site, sweep or shovel the affected roadway thoroughly. Street washing is not permitted. After sediment is recovered, transport it to a controlled sediment disposal area. Applicable BMPs include: * Stabilized Construction Entrance — BMP C105 ❑ Wheel Wash — BMP C106 ❑ Construction Road/Parking Area Stabilization — BMP C107 * Other: Use existing paved driveway for demo and site clearing then install construc 3. Control Flow Rates — Flow control BMPs must be used to protect properties and waterways downstream of construction sites from erosion and discharge of turbid waters. A combination of drainage swales and possibly a sediment trap may be used to control runoff and trap associated sediment before it leaves the construction site. Applicable BMPs include: ❑ Interceptor Dike and Swale — BMP C200 ❑ Straw Wattles — BMP C235 ❑ Sediment Trap — BMP C240 ❑ Other: 4. Install Sediment Controls — Sediment barriers should be used downslope of disturbed areas. Sediment barriers are intended to create a barrier to slow the sheet flow of stormwater and allow the sediment to settle out behind the barrier. Do not used sediment 2 2/2019 Stormwater Pollution Prevention Plan (SWPPP) Short Form For Small and Medium Construction Projects barriers in streams, channels, ditches, or around inlets/outlets of culverts. Sediment barriers shall be clearly identified on the plan. Design, install, and maintain effective erosion and sediment control BMPs to minimize the discharge of pollutants from the site. BMPs must address factors such as the amount, frequency, intensity, and duration of precipitation. Applicable BMPs include: R Silt Fence — BMP C233 ❑ Vegetated Strip — BMP C234 ❑ Straw Wattles — BMP C235 ❑ Other: 5. Stabilize Soils — Protect exposed and unworked soils to reduce erosion from rainfall and wind. Between October 1 and April 30, no soil shall remain uncovered for more than 2 days. From May 1 to September 30, no soil shall remain exposed for more than 7 days. Mulch can be applied to any site where soil has been disturbed and the protective vegetation has been removed. Erosion control blankets may be suitable for post - construction site stabilization or for temporary stabilization of highly erosive soils, such as on steep slopes and areas where vegetation is slow to establish. Applicable BMPs include: ❑ Temporary and Permanent Seeding — BMP C120 0 Mulching — BMP C121 ❑ Nets and Blankets — BMP C122 � Plastic Covering — BMP C123 ❑ Sodding — BMP C124 ❑ Topsoiling — BMP C125 ❑ Other: 6. Protect Slopes — Design, construct, and phase projects in a manner to minimize erosion. Protect slopes by diverting water at the top of slopes. Reduce runoff velocity by minimizing the length of the slope. This can be done by terracing and roughening slope sides. Seeding and establishing vegetation can also help protect slopes. Applicable BMPs include: ❑ Temporary and Permanent Seeding — BMP C120 ❑ Nets and Blankets — BMP C122 � Plastic Covering — BMP C123 ❑ Interceptor Dike and Swale — BMP C200 ❑ Other: 3 2/2019 Stormwater Pollution Prevention Plan (SWPPP) Short Form For Small and Medium Construction Projects 7.

Inlet protection shall be installed on all drains within 500' of the project site, including those that become operable during construction. Maintain 2/3 of the available storage in inlet protection devices at all times. Inlet protection shall be removed after final stabilization of the site. Applicable BMPs include: 0 Storm Drain Inlet Protection — BMP C220 ❑ Other: 8. Stabilize Channels and Outlets — Design, construct, and stabilize all on -site drainage channels to prevent erosion from a 10-year 24-hour frequency storm for the developed conditions. Provide stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent stream banks, slopes and downstream reaches at the outlets of all conveyance systems. The best method of stabilizing channels is to line the channel completely with a blanket product and then add check dams as necessary to function as an anchor and slow the flow of water. Applicable BMPs include: ❑ Channel Lining — BMP C202 ❑ Outlet Protection — BMP C209 ❑ Other: 9. Control Pollutants — Handle and dispose of all pollutants, including waste materials and demolition debris that occur on -site in a manner that does not contaminate surface water.
