ECC UGENE ITY OUNCIL AIS GENDA TEM UMMARY Work Session: Stormwater Development Standards Meeting Date: March 13, 2006 Agenda Item Number: C Department: Public Works Engineering Staff Contact: Peggy Keppler www.eugene-or.gov Contact Telephone Number: 682-2869 ISSUE STATEMENT The purpose of this work session is to present the stormwater development standards to the council and open discussion on the proposed code amendments to Chapter 9 (Attachment A: Draft Ordinance and Exhibit A of the Draft Ordinance) in preparation for the public hearing scheduled for April 10, 2006. The proposed stormwater development standards are regulations for locating, designing, constructing, and maintaining stormwater facilities, applicable to new development. A companion design manual, the Eugene Stormwater Management Manual, sets forth approved stormwater facilities (Attachment D) and is being prepared for the engineering design community. The Stormwater Management Manual will be adopted administratively and staff anticipates that the manual will be adopted concurrent with adoption of the ordinance. BACKGROUND The proposed code amendments are intended to implement stormwater development standards as a component of the City’s Stormwater Program initiated with the adoption of the Comprehensive Stormwater Management Plan (CSWMP) and as required through the Department of Environmental Quality (DEQ)’s issuance of the City’s National Pollutant Discharge Elimination System (NPDES) Permit. In 1999 and early 2000, a Stormwater Department Advisory Committee (DAC) worked with Public Works staff to review the stormwater management strategies developed as part of the stormwater basin planning. The stormwater management strategies included a long-term multiple objective capital improvement projects list, proposed waterway protection measures, and basic concepts for proposed stormwater development standards for water quality. A summary of the DAC recommendations related to stormwater development standards is provided in Attachment B. On July 10, 2000, staff presented the proposed stormwater management strategies to the council, including DAC-recommended stormwater development standards concepts, and the related financial impacts analysis. The council approved the proposed stormwater management strategies and directed staff to proceed with broader public outreach. Following the DAC recommendations and subsequent public outreach on the stormwater management strategies, staff developed a draft ordinance and a draft Best Management Practices (BMP) Manual for stormwater development standards. Although City projects were beginning to incorporate water quality BMPs, implementation of stormwater development standards for private development was put on hold until after the implementation of Land Use Code Update in 2001.
