Storm Water Easement and Maintenance Agreement Page 5 of 19 EXHIBIT `B' Stormwater Pollution Prevention Plan For Auburn Volkswagen SEPA# 01-0036 FAC #01-0042 BLD #01-0296 Site Address: The project is located in Section 6, Township 21 North, and Range 5 East, WM., on the West Side of Auburn Way North and approximately 500 feet north of the intersection of Auburn Way North and 30`h Street NE in the city of Auburn. The site address is 3025 Auburn Way North, Auburn, WA 98002. The tax Parcel Number is 000400 0039. aoIntroduction: o The project proposes to construct a new Subaru Dealership on lot 1 of short plat (file no. SPL00-0001). The site is located at 3025 Auburn Way North (see figure 1). Zoning of the site is C-3, which allows the intended use out right. The site occupied by the existing Auburn m Volkswagen Dealership building. The existing dealership will be removed as part of this project. The site occupies Lot 1 (zoned C-3) of the short plat. The site is bound by light industrial on the West (zoned M1) and the Volkswagen dealership on the North (zoned C-3). ' The dealership will consist of a 20,000 SF building with approximately 2.5 acres of paved parking, display space, and access isles. The completed project will provide a combination wet/detention pond for storm water treatment and detention of storm water. The pond will be located along the west property line. See tributary area map in appendix B for delineation of these areas. The on-site storm water will be collected in a series of catch basins and discharged into the storm pond. The proposed site grades will not allow for gravity flow to the pond for the entire site. A small area at the entrance from Auburn Way wil}discharge directly to Auburn Way due to grades. Based on our grading plans, this area consists of approximately 1,600 SF of area. The site plan concept allows for vehicular traffic across the property line. To allow the movement, the grades must match between the two sites. Currently the Subaru dealership is paved with an on-site storm system. The existing system provides only an inverted tee for treatment with little or no detention. 'The runoff is discharged to the city's storm system in Auburn Way North. The proposed conditions will improve the drainage in the area by providing storm water treatment and detention for the areas draining to the new facilities. The 1,600 SF at the entrance can not gravity flow to the pond. This areas is currently paved and will continue to discharge to the city systems with out change. The proposed drainage system consists of expanding the existing storm pond for the Volkswagen and discharging the runoff from both the Volkswagen and Subaru sites into the Storm Water Easement and Maintenance Agreement Page 6 of 18 pond. The existing Volkswagen pond is a combination wet pond / detention pond. The pond discharges to a catch basin along the Auburn Way frontage. The discharge system for the pond includes an oil water separator tee fitting. The city system ultimately discharges into the Green River. Plan Goal: The plan has two goals; 1) limit the contact between pollutants and stormwater runoff and 2) direct as much of the runoff as possible to the combination detention/wet pond for peak flow control and treatment. Prevention BMP's Prevention Best Management Practice's (BMP's) are actions taken by a person or business to reduce the amount of pollution reaching surface and ground waters. BMP's for this site could include: C93, Altering the activity (e.g., substitute non-toxic products, recycle used oil, route floor drains to sanitary sewer from storm sewer) C53 Enclosing or covering the activity that may introduce pollution to stormwater (e.g., a~ building a roof) a co ' 03 Segregating the activity (e.g., diverting runoff away from an area that is contaminated) o; cz The catch basins shall have stenciled next to them "DUMP NO WASTE - DRAINS TO STREAM" ~1 0_4 C-3 The parking lot shall be swept on a regular basis to remove debris. C,S The conveyance system and storm pond shall be cleaned to remove trash and sediments. c>s Routing runoff from the activity to a treatment alternative (e.g., to a wastewater treatment facility, sanitary sewer, or stormwater treatment area) Research on urban runoff in the Puget Sound area and elsewhere has found oil and grease, nutrients, organic substances, toxic metals, bacteria, viruses, and sediments at unacceptable levels. Effects of contaminated runoff include closure of shellfish harvesting areas and swimming areas, mortality of young fish and other aquatic organisms, tumors on fish, and impairment of fish reproduction. Of Particular interest are drives and parking areas. Because of heavy vehicle usage, the concentration of oil and grease in stormwater may exceed the Ecology guidelines of 10 mg/1. Although there are no local data to confirm this view, limited research in the San Francisco Bay area found the mean concentration of oil and grease in stormwater •to exceed 10 mg/ 1. Storm Water Easement and Maintenance Agreement Page 7 of 18 Treatment BMP's tg~ erl co 0 co cn N .Q cca. Different types of ponds are designed for different purposes. For example, wet ponds primarily provide treatment of stormwater. Dry ponds or detention ponds are designed to provide storage for stormwater and gradually release it downstream or allow it to filter into the ground. The Auburn Volkswagen Storm system includes a combination detention/wet pond. This type of pond provides stormwater treatment at the bottom of the pond and detention on the top. The wet pond or treatment portion of the pond was designed to meet current City of Auburn standards. The treatment portion of the pond provides a permanent pool of water for pollution up take. The pool of water allows for sediments to drop out, and supports plant live, which filters and provides biological uptake of pollution. This pool of water provides00 volume greater than the volume of the 6-month 24-hour rainfall event, a minimum depth of 3-feet, and a surface area greater than I% of the paved parking lot as required by city standards. The detention pond portion stores the runoff generated by the site and releases the run off at predevelopment rates. An outlet control devise regulates the discharge from the pond and is located in a manhole on the south end of the pond. The control devise consists of holes with diameters calculated to limit the flows to the pre-existing rates. The pond and control manhole must be kept clear of trash and other debris to prevent blockages of the system. YOUR STORMWATER FACILITIES This section consists of two parts that are to be used together: the Facility Key and the Site Plan. Look on the site plan and identify the numbers denoting a feature of the system. Then look on the facility key to see what that feature is called and which checklist applies. FACILITYKEY The stormwater facility in your neighborhood is comprised of the following elements: Type offeature & Checklist Name Location o4n Site. Plan Pond 1 Catch Basins, Manholes, and Inlets 2 Grounds and Landscaping 3 Conveyance Pipes, Ditches, and Swales 4 Storm Water Easement and Maintenance Agreement Page 8 of 18 QUICK LIST The following list is an abbreviated checklist of the most common types of maintenance you should have to do. Please try and go over this checklist after heavy rains. This is a bare minimum and should be done in conjunction with the other checklists in order to make your maintenance program effective. Check catch basin grates to see that they are not clogged or broken. Remove twigs, leaves, or other blockages. Contact the local jurisdiction to replace the grate if it is broken. Check inlet and outlet pipes for blockages. Clear all blockages. 40 011 ~ Check filter strip, swale and pond walls for erosion or caved in areas. 0 oar Check riprap (rocks) at the inlets and outlets of culverts and other pipes.

This packet has been. customized so that only the checklists for your facilities are included. If you feel you are missing a checklist, or you have additional facilities not identified or addressed in this packet, please contact your local jurisdiction. The checklists are in tabular format for ease of use and brevity. Each checklist tells you what part of the feature to check, how often to check it, what to check for, and what to do ,.'",out it. Log sheets are included toward the end of the chapter to help you keep track of when you last surveyed the storm drainage system. Although it is not intended for the maintenance survey to involve anything too difficult or strenuous, there are a few tools that will make the job easier and safer. These tools include: to er'A cs A flashlight. c~ c,>3 A long pole or broom handle. ca c, c,3 Some kind of pry bar or lifting tool for pulling manhole and grate covers. vescr3 Gloves. 17 ri c*4; . ate. A listing of resources is included in the next chapter. Here you will find the phone numbers of the agencies referred to in the tables, as well as the contractor and consultants that designed and constructed your facilities. SAFETY WARNING: Due to OSHA regulations you should never stick your head or any part of your body into a manhole or other type of confined space. When looking into a manhole or catch basin, stand above it and.use the flashlight to help you see. Use a pole or broom handle that is long enough when you are checking sediment depths in confined spaces. NO PART OF YOUR BODY SHOULD BREAK THE PLANE OF THE OPEN HOLE.
