Redwood City <br /> Water Quality Monitoring Program Plan <br /> <br /> <br />© 2014 DKF Solutions Group, LLC Page 8 of 41 <br /> <br /> Stulsaft Branch <br /> Jefferson Branch (upper) <br /> Kensington Branch <br /> Cordilleras Creek <br /> Little River Creek <br /> <br />2. Background monitoring will occur twice each year, once in dry weather and once in wet <br />weather conditions <br /> <br />3. Background monitoring will measure the following constituents: <br /> Enterococcus, Total Coliform/Fecal <br /> BOD (biological oxygen demand) <br /> pH <br /> Temperature <br /> <br />4. Background monitoring will be performed by assigned staff in the Wastewater Division <br /> <br />5. Samples will be analyzed in accordance with Sections 6.0 and 7.0. <br /> <br />6. Sample results will be retained in the City’s files located Wastewater Day Room and on <br />the Public Works shared network drive. <br /> <br /> <br /> B. Surface Waters of Concern <br /> <br />For the purposes of this Plan, surface waters are defined as all waters whose surface is naturally <br />exposed to the atmosphere, for example, rivers, lakes, reservoirs, ponds, streams, <br />impoundments, seas, estuaries, etc., and all springs, wells, or other collectors directly influenced <br />by surface water. In addition, the City will also identify and evaluate areas where collection <br />system pipelines and force mains cross over or under waterways as these crossings can require <br />additional resources and equipment to properly address any SSO from these collection system <br />assets. <br /> <br />Surface waters of concern are those surface waters within the City’s service area that may be <br />impacted by a sanitary sewer overflow from the City’s sanitary sewer collection system. Prior <br />planning, review and evaluation of potential failure mechanisms can help minimize any potential <br />impacts to surface waters or storm water infrastructure when and if the WQMP must be invoked. <br />Any review of these important areas of potential surface water contamination in advance of an <br />SSO should allow the City to be better prepared to respond to an SSO with the proper equipment <br />and a better understanding of the procedures that may need to be invoked during the SSO such <br />as flow rate of a creek or stream, and potential areas of significant environmental concern such <br />as shell fish beds or fish habitats. In addition, having all storm water infrastructure located on the <br />collection system field maps will help the City’s responders quickly determine if SSOs may flow <br />into storm drains reach and impact surface waters. <br /> <br />The following (Table 5.1) are the surface waters of concern within the City’s jurisdiction: <br />6.2.A. - Page 174
