ATTACHMENT B E4 BMP Fact Sheet Stormwater Development Standards Responsible Department/Division: BMP Contact: Public Works / Engineering Engineering Division Director BMP Description: Finalize, implement, and enforce stormwater development standards: regulations for locating, designing, constructing, and maintaining water quality facilities for new development and significant re-development. (Note: Stormwater development standards are controls for postconstruction water quality. Standards for erosion control during construction related to new development are covered under BMP E2). Background: There is a direct link between impervious surfaces associated with stormwater runoff from urban development and the quality of the City’s surface and ground waters. As properties develop, the impervious surfaces that are created increase the amount of runoff during rainfall events, disrupting the natural hydrologic cycle. Without control, these conditions erode stream channels and limit groundwater recharge. New and expanded parking lots, roadways, and rooftops increase the pollution levels in stormwater runoff that is transported to streams, rivers, and groundwater resources. Protecting these waters is vital for a great number of uses, including fish and wildlife habitat, recreation, and drinking water. The City’s proposed stormwater development standards will: address future water quality impacts from new development; address the existing water quality condition through redevelopment; ensure that sensitive headwater streams are not further impacted from new development; and address high pollutant land uses and activities. Stormwater development standards will be implemented by adoption of an ordinance and associated design manual, establishment of an inspection/enforcement program, identification and budgeting of necessary resources to implement the new program, training related to the new requirements, evaluation, and adaptive management. BMP Activities: Complete review process with Stormwater Department Advisory Committee, a group of • citizens providing feedback on City staff recommendations. Conduct presentations to stakeholder groups and host an open house to obtain feedback • on the proposed standards in advance of the adoption process. Determine personnel needs to oversee the design review, inspection, enforcement, • monitoring and maintenance of water quality facilities. Review Street Design Standards for consistency with water quality standards; evaluate the • need for any revisions to street design standards or related implementation processes. Finalize the draft stormwater development standards and process for adoption by elected • officials by the end of Permit Year Three. Provide education and training for City staff and the design and development community. • Second Annual Report Part II – Evaluation Report December 2005 Page II-92
