LLC 1803 154d'Street Ct.N W Gig Harbor,Washington 98332 Reference: Stormwater Quality for Proposed Church Located on NE Gladwin Road,Parcel 12331- 32-00040,Belfair,Washington,98528 Dear Mr.Christensen, Envirotech Engineering (Envirotech) is providing this letter concerning the stormwater quality for the future development of the proposed church that will be located at the referenced property. Due to the size of the development, an engineered stormwater management plan will be required to address both quantity and quality of stormwater due to the expected development. Per Mason County Code, an engineered plan will completed and accepted by the regulating agency which will include provisions for mitigating pollution generated on-site by following the 2005 Washington State Department of Ecology Stormwater Manual. Pollution may be mitigated by various drainage facilities including bio-infiltration swales, bio-infiltration ponds, bio-filter strips, detention facilities and/ or other Department of Ecology accepted methods. In addition, Ecology requires that the bottom of any bio-infiltration facility shall be a minimum of 3 feet above any perched ground water and/or relatively impermeable substrate such as clay or glacial till. It is deemed by Ecology that appropriate drainage facilities plus 3 feet of free draining soil below the drainage facility is adequate pollution mitigation. Based on our site and subsurface observations, pollution mitigating drainage facilities are feasible for this project and are required for development. Please contact Michael Staten at 360-275-9374 if you have any questions or require additional information.
