(1) The location, design, construction, and management of all shoreline uses and activities shall protect the quality and quantity of surface and groundwater adjacent to the site.

(2) When applicable all shoreline development should comply with the requirements of the latest version of the Washington State Department of Ecology’s (Ecology) Stormwater Management Manual for Eastern Washington.

(3) Potentially harmful materials, including but not limited to oil, chemicals, tires, or hazardous materials, shall not be allowed to enter any body of water or wetland, or to be discharged onto the land. Potentially harmful materials shall be maintained in safe and leak-proof containers.

(4) When applicable, new development shall provide stormwater management facilities designed, constructed, and maintained in accordance with the latest version of the Washington State Department of Ecology’s (Ecology) Stormwater Management Manual for Eastern Washington, including the use of BMPs. Additionally, new development shall implement low impact development techniques where feasible and necessary to fully implement the core elements of the Surface Water Design Manual.

(5) For development activities with the potential for adverse impacts on water quality or quantity in a fish and wildlife habitat conservation area, a critical area report as prescribed in Article V, Critical Areas, of this chapter shall be prepared. Such reports should discuss the project’s potential to exacerbate water quality parameters which are impaired and for which total maximum daily loads (TMDLs) for that pollutant have been established, and prescribe any necessary mitigation and monitoring.

(6) All materials that may come in contact with water shall be constructed of materials, such as untreated wood, concrete, approved plastic composites or steel, that will not adversely affect water quality or aquatic plants or animals. Materials used for decking or other structural components shall be approved by applicable state agencies for contact with water to avoid discharge of pollutants from wave or boat wake splash, rain, or runoff. Wood treated with creosote, copper chromium, arsenic, or pentachlorophenol is prohibited in shoreline waterbodies. (Ord. 484 § 2, 2014)
