The tax parcel number is 7652500000. Introduction; This storm drainage technical information report has been prepared to address the City of Auburn's site development and storm drainage requirements for the proposed 'The Seasons" project located at 12722 SE 312" Street. The site has an area of approximately 15.7 acres and is currently undeveloped. The subject site will be developed for commercial retail space and multi family dwelling units. The subject site proposes 22 buildings with approx. 38,500 at commercial space, 330 dwelling units, on-grade parking for approx. 598 cars, and 11,625 at recreation building. The western portion of the site will remain undeveloped as part of a wetland complex. According to the 2005 King County Surface Water Design Manual for storm water management, the County 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, building and pavement areas in a series of catch basins. This water will be conveyed by storm drainage pipe to (3) separate storm water detention/water quality vaults, Vault E2 located at the northeast corner of the site, Vault El and Vault W1 located adjacent to SE 312'" Street below the parking area. The storm water from Vault E2 will be released into to a dispersion trench east of the vault and surface flow approx. 100 feet to an existing stream. Storm water from Vault El discharges to a stormflter catch basin system which then discharges to SiWa4rRa eut and Malnteni Ameres Peg,7MIx a 12' pipe system heading easterly and connects to an existing catch basin within SE 312" Street near the southeast corner of the site. The storm water from Vault W1 discharges at the southeast corner of the vault and heads south to a stormfiller vault system, then discharges in a 12' pipe and heads southerly approx. 73 feet to a connection to the public drainage system within SE 312th Street. 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 1425-649-7000. 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, August 2001) No. 3 - Closed Detention Vault No. 4 - Control Structure/Flow Restrictor No. 5 - Catch Basins No. 12 - Welvaults No. 15 - Stormflter Treatment BMP'S: Three combined detention/water quality vaults have been installed to treat runoff for conventional pollutants. The wetvaults were designed to treat 64% of the 2-year storm event (water quality storm) for water quality treatment. In addition, the detention pond was 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. A stormfilter system also provides enhanced basic storm water om meat sm Wintaw¢e Agme ante Page& fIs water quality treatment following each welvault. The stormflter vault for Vault E1 is integrated inside the detention vault, all other stormfilters are in separate catch basins or vaults. InspectionlMaintenance Regular inspections of the drainage facilities should be carried oultwice 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. 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 (3) underground combined detentionMeNault facilities 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 Person of Responsibility The Seasons I, LLC Attn: Tom Neubauer 375 118th Ave SE Bellevue, WA 98005 Phone: (425) 453-9551 Design Engineer: CPH Consultants,LLC Adn.

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.
