This preliminary report describes the characteristics of urban runoff affecting Coyote Creek, sources of urban runoff pollutants, effects of urban runoff and potential controls for urban runoff. Local urban runoff characterization information is summarized, and sources of urban runoff pollutants are being investigated and include sampling from source areas such as street surfaces, parking lots, landscaped areas and rooftops. Various biological sampling techniques were used to evaluate the fish, benthic macroinvertebrates and attached algae conditions in the creek, above and within the urban area. Creek water and sediment samples were also obtained and analyzed for a broad list of parameters. In most cases, very pronounced gradients of these creek quality indicators were observed, with the urbanized portion of the creek being significantly degraded. Current additional monitoring is being conducted to identify the urban runoff control goals necessary to improve creek quality to adequate levels.
