SEP11 -0016 GRA NO. GRA11 -0021 Site Address. The project is located in NW '/< of Section 18, T21 N, RSE, W M., at 727 A Street NE in Auburn WA. The tax parcel numbers are 605340 -0525 & - 0520 Introduction- This storm water pollution prevention plan has been prepared to address the City of Auburn's site development and storm drainage requirements for the proposed Terry Home II located at 727 A Street NE. The site will have an area of approximately 0 50 acres after the proposed street vacation and is currently a level grass field after the prior single family residence was demolished. The subject site will be developed to include a 5,478sf building along with associated parking, maneuvering, and landscape areas. The building will be single story wood framed (type 5B construction) and will be used as a licensed boarding home (R -2 occupancy) According to the City of Auburn's Construction Standards for storm water management, the city requires storm water quantity and quality control to all proposed developments, unless exempt. Due to the small size of the site, the project is exempt from detention requirements. We have proposed to collect all of the storm water runoff from the landscape, building and pavement areas in a series of catch basins connected by perforated pipes in washed rock trenches. Parking lot water will flow thru a grassed area for approximately 60 feet and to a catch basin with an oil /water separator elbow prior to entering the trench system. Site water will be conveyed to the public storm system at the NE corner of the site. Here the storm water will be released into 24" diameter truck line that flows to the East. Storm Water Easement and Maintenance Agreement Page 7 of IS Plan Goal: The specific purpose for the storm water facility is to minimize pollution that is typically associated with modern development. In general, pollution from motor vehicles and pollution generated from erosion. Attached to this narrative is a maintenance manual, which offers guidelines to the owner for storm water facility maintenance. Prevention BMP'S The catch basins shall have stenciled on them "DUMP NO WASTE — DRAINS TO STREAM." The owner shall be responsible for sweeping the lot, installing storm drainage stenciling and provide spill control procedures. In case of spill call DOE at 1-425- 649 -7000 The catch basins, detention /wetpond, and control structures will be visually inspected for accumulation of debris and silt and will be maintained as required by this pollution prevention plan and attachments. • Maintenance Standards for Drainage Facilities (from the Department of Ecology Storm Water Manual, February 2005) No 5 —Catch Basins No 8 — Grass Swale No 10 —Filter Strip No 24 — Pervious Concrete Treatment BMP'S: A grass swale / filter strip area combined with an oil /water separator catch basin has been installed to treat runoff for conventional pollutants. The walks have been designed as pervious concrete to eliminate runoff, and the entire site collects to a perforated pipe / wash rock trench system that will allow storm water to infiltrate as /if possible before release to the public storm system. The site is exempt from detention requirements. Inspection /Maintenance: Regular inspections of the drainage facilities should be carried out twice per year, in the spring and fall. The responsible party should keep records of these inspections available for review by the City Additional inspections may be required after severe storms. Storm Water Easement and Maintenance Agreement Page 3 of 15 Routine maintenance of the site will include mowing, care of landscaping and the removal of trash and debris from the drainage system. The parking lots and driveways should be kept clean and in repair Events such as major storms or heavy winds will require immediate inspections for damages. To ensure proper water quality and treatment, the grass swale / filter strip area and catch basins must be properly maintained. Be careful to avoid introducing landscape fertilizer to receiving waters or groundwater Catch basins shall be cleaned when sump is 1/3' full of sediment or debris.

The facility - specific maintenance standards contained in this section are intended to be conditions for determining if maintenance actions are required as identified through inspection. They are not intended to be measures of the facility's required condition at all times between inspections. In other words, exceeding these conditions at any time between inspections and /or maintenance does not automatically constitute a violation of these standards. However, based upon inspection observations, the inspection and maintenance schedules shall be adjusted to minimize the length of time that a facility is in a condition that requires a maintenance action.
