The Tax Parcel # 158060-0240 Introduction: This stormwater pollution prevention plan has been prepared to address the City of Auburn's site development and storm drainage requirements for the proposed Chadek Building project located at 3416 B Street NW. The site has an area of approximately 4.085 acres. The proposed project will construct a 52,640 sf commercial building with associated paved parking, utilities and landscaping on the South portion of the property. The North 98 or feet of the site will be enhanced / remain as wetlands per plans by J.S. Jones & Associates. The existing site is vacant and has no storm drainage system other than (2) pipes under B Street NW that cross connect the site to the drainage ditch on the West side of the road. Existing utilities are located on or near the site and do not require any major extensions and only minor work in the R.O.W. Site access will be from B Street NW. A detention pond is proposed to provide storm water detention for the paved areas and landscaping South of the building, and a Model AS-3 Aqua-Swirl Concentrator to provide water quality control for this storm runoff. The building roof runoff will drain to the wetland area to maintain the existing hydrology. 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. We have proposed to collect all of the storm water runoff from the landscaped and pavement areas South of the building in a series of catch basins. Storm Water Easement and Maintenance Agreement Page 8 of 19 This water will be conveyed by storm drainage pipe to the storm water detention pond located in the SW corner of the site, and then to the Aqua-Swirl. The water will then be released through the existing 18" pipe under B Street NW and flow North in the ditch. Should overflow occur the water would flow over the public sidewalk and enter the existing storm drainage system in B Street NW. The runoff from the building roof will be "clean" and will discharge directly into the wetland to maintain existing hydrology. 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 GROUND". 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 pond, control structure, and Aqua-Swirl 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 No. 1 - Detention Pond No. 4 - Control Structure/Flow Restrictor No. 5 - Catch Basins Aqua-Swirl System Document (attached) (Department of Ecology Storm Water Manual, August 2001). Storm Water Easement and Maintenance Agreement Page 9 of 19 Treatment BMP'S An Aqua-Swirl AS-3 has been installed to treat runoff for conventional pollutants. The Aqua-Swirl was designed to treat 1.8cfs. In actuality the Aqua-Swirl will treat 100% of the 100 year storm peak flow of 0.86cfs and provide over 80%TSS removal. In addition, the detention pond has been designed to detain the volume created from releasing half the existing 2-year, 10, 25, and 100-year storm events, while holding the developed 2-year, 10, 25, and 100-year storm volumes. The City of Auburn Utilities Section is to review and approve any changes to this stormwater Pollution Prevention Plan prior to changes in its implementation. Additionally, any changes in ownership or person of responsibility are to be reported to the City Utilities Sections. Storm Water Easement and Maintenance Agreement Page 10 of 19 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 seasonal storms. 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 stormwater detention pond, catch basins, pipes and Aqua-Swirl 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.

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.
