Receiving Water Condition Assessments <br /> The ultimate goal of stormwater trash management in the Bay Area is to significantly reduce <br /> the amount of trash found in receiving waters. In the last decade, San Mateo County Permittees <br /> and volunteers have collected data on the amounts of trash removed during cleanup events. <br /> More recently, Permittees have conducted trash assessments in creek and shoreline hotspots <br /> using standardized assessment methods. In an effort to answer the core management question <br /> Have trash problems in receiving waters been resolved?,the City of Redwood City plans to <br /> continue conducting receiving water condition assessments at trash hot spots a minimum of <br /> one time per year.Assessment will be conducted consistent with Permit hot spot cleanup and <br /> assessment requirements.Additional information on receiving water assessment methods can <br /> be found in the SMCWPPP Pilot Trash Assessment Strategy(SMCWPPP 2014). <br /> 4.2 BASMAA "Tracking California's Trash" Project <br /> The SMCWPPP Pilot Assessment Strategy described in the previous section recognizes that <br /> outcome-based trash assessment methods needed to assess progress toward trash reduction <br /> targets are not well established by the scientific community. In an effort to address these <br /> information gaps associated with trash assessment methods,the Bay Area Stormwater <br /> Management Agencies Association (BASMAA),in collaboration with SMCWPPP,the 5 Gyres <br /> Institute, San Francisco Estuary Partnership,the City of Los Angeles,and other stormwater <br /> programs in the Bay Area,developed the Tracking California's Trash Project.The Project is funded <br /> through a Proposition 84 grant awarded to BASMAA by the State Water Resources Control Board <br /> (SWRCB) who recognized the need for standardized trash assessment methods that are robust and <br /> cost-effective. <br /> The Project is intended to assist BASMAA member agencies in testing trash assessment and <br /> monitoring methods needed to evaluate trash levels in receiving waters,establish control measures <br /> that have an equivalent performance to trash full capture devices,and assess progress in trash <br /> reduction over time.The following sections provide brief descriptions of tasks that BASMAA will <br /> conduct via the three-year Project. Full descriptions of project scopes, deliverables,and outcomes <br /> will be developed as part of the task-specific Sampling and Analysis Plans required by the SWRCB <br /> during the beginning of the Project.The Project is currently underway and will continue through <br /> 2016. <br /> 4.2.1 Testing of Trash Monitoring Methods <br /> BASMAA and the 5 Gyres Institute will evaluate the following two types of assessment methods as <br /> part of the Project: <br /> 62 <br />
