SD-13 <br />Storm Drain Signage <br />— DRAINS TO OCEAN" and/or other graphical icons to discourage illegal dumping. <br />■ Post signs with prohibitive language and/or graphical icons, which prohibit illegal dumping <br />at public access points along channels and creeks within the project area. <br />Note - Some local agencies have approved specific signage and/or storm drain message placards <br />for use. Consult local agency stormwater staff to determine specific requirements for placard <br />types and methods of application. <br />Redeveloping Existing Installations <br />Various jurisdictional stormwater management and mitigation plans (SUSMP, WQMP, etc.) <br />define "redevelopment" in terms of amounts of additional impervious area, increases in gross <br />floor area and/or exterior construction, and land disturbing activities with structural or <br />impervious surfaces. If the project meets the definition of "redevelopment", then the <br />requirements stated under " designing new installations" above should be included in all project <br />design plans. <br />Additional Information <br />Maintenance Considerations <br />Legibility of markers and signs should be maintained. If required by the agency with <br />jurisdiction over the project, the owner/operator or homeowner's association should enter <br />into a maintenance agreement with the agency or record a deed restriction upon the <br />property title to maintain the legibility of placards or signs. <br />Placement <br />■ Signage on top of curbs tends to weather and fade. <br />■ Signage on face of curbs tends to be worn by contact with vehicle tires and sweeper brooms. <br />Supplemental Information <br />Examp les <br />■ Most MS4 programs have storm drain signage programs. Some MS4 programs will provide <br />stencils, or arrange for volunteers to stencil storm drains as part of their outreach program. <br />Other Resources <br />A Manual for the Standard Urban Stormwater Mitigation Plan (SUSMP), Los Angeles County <br />Department of Public Works, May zooz. <br />Model Standard Urban Storm Water Mitigation Plan (SUSMP) for San Diego County, Port of <br />San Diego, and Cities in San Diego County, February 14, zooz. <br />Model Water Quality Management Plan (WQMP) for County of Orange, Orange County Flood <br />Control District, and the Incorporated Cities of Orange County, Draft February 2003. <br />Ventura Countywide Technical Guidance Manual for Stormwater Quality Control Measures, <br />July zooz. <br />2 of 2 California Stormwater BMP Handbook January 2003 <br />New Development and Redevelopment <br />www.cabmphandbooks.com <br />
