Tahja, P/W- Co. Hydr. Engr. DCD WO#9933 SUBJ: Stormwater Report Review NAME: North Mason Eagles BLD99-33 Allan, A Parking Lot Storm Drainage Analysis was received and reviewed by Public Works and a response delivered to DCD on April 29, 1999. A copy of the review IDC was faxed to Kurtis Carpenter who represents the North Mason Eagles(NME) organization on May 4, 1999. Public Works review of the drainage plan found that flow attenuation in the form of proposed g downstream erosion control discharge rates is being required by WSDOT as the recipient of runoff from this project. The site plan delivered to Public Works with work order#9933 indicates a pond is located or is to be created between the proposed parking area and State Highway 3. The sketch doesn't indicate whether the pond is existing or proposed, or give any indication of its dimensions. At this time,Public Works is awaiting delivery of a revised stormwater plan that either conforms to WSDOT's downstream erosion control discharge rates, or a plan developed by an engineer indicating how runoff is intended to be retained on the site. Please feel free to contact me at County extension 461 if you have any questions regarding this review, or if I can be of any assistance. Sir cerely, 1 64 ). - /5&1, Alan A.
