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 Facility Building project located at 12401 SE 320th Street, Auburn, WA 98092. The site has an area of approximately 0 3 acres and is currently undeveloped with some areas of existing pavement. The subject site is situated between two existing building on the campus. The subject site will be developed to accommodate the community college facilities department. The subject site will be composed of a new building surrounded by a new access driveway and paved parking area. A 5 -foot wide paved walkway will be constructed. 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, building and pavement areas in a series of catch basins. Roof runoff will be conveyed by storm drainage pipe to two 50 -foot long dispersion trenches located within the forested area south of the new facilities building. Storm Water Easement and Maintenance Agreement Page 7 of 13 Here the storm water will be dispersed downstream through the existing vegetation for more than 50 feet. Runoff eventually reaches the Green River Pavement runoff is filtered through the permeable pavement to the underlying soil or conveyed to the existing storm system that discharges to an existing detention vault. Flow control and water quality are not required for this project because the developed peak discharges are below the threshold requirements. 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 City of Auburn Surface Water Storm Manual, November 2009) No. 5 — Catch Basins No. 24 — Pervious Pavements Treatment BMP'S: Water quality treatment is not required for this project because the majority of the new impervious area is non - pollution generating surface. The majority of the runoff will be filtered through the existing underlying soil layer Storm Water Easement and Maintenance Agreement Page 8 of 13 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. 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 filtration of runoff into the underlying soil layer, the dispersion trenches and permeable pavers must be properly maintained. Be careful to avoid introducing landscape fertilizer to receiving waters or groundwater If wetpond side slopes become eroded over 2" deep, stabilize by using appropriate erosion control measures (e.g., rock reinforcement, planting of grass, compaction) Catch basins shall be cleaned when sump is 1/3' full of sediment or debris Person of Responsibility: Mike Bingisser, Facilities Project Officer Green River Community College 12401 SE 3201h Street Auburn, WA 98092 (253) 288 -3329 Design Engineer: Reid Middleton, Inc. 728134 th Street SW, Suite 200 Everett, WA 98204 Attn. Mark Davis (425) 741 -3800 Plan and/or Information Updates: The City of Auburn Storm Drainage Utility section is to review and approve any changes to this Storm Water 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 Storm Drainage Utility section.

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.
