Stormwater Monitoring Program – Beach Cities Watershed Management Group |
The Beach Cities Stormwater Monitoring Project consists of implementing the Beach Cities Watershed Management Group’s (BCWMG) Stormwater Monitoring Program in accordance with the Los Angeles County Municipal Separate Storm Sewer System (MS4) Permit mandated by Section 402 of the Federal Clean Water Act. The BCWMG includes the southern California coastal cities of Manhattan Beach, Hermosa Beach, Redondo Beach, and Torrance. The objective of the MS4 Permit is to ensure that discharges in the County of Los Angeles do not cause or contribute to the exceedance of water quality standards in regional water bodies. The MS4 Permit includes monitoring requirements for applicable TMDL standards, receiving water quality, stormwater outfall flows, and non-stormwater (dry weather) flows.
Since 2016, EcoKai has been providing monitoring services to BCWMG that include performing field water quality sampling during storm events, installation and maintenance of instrumentation within storm drains to measure water flow, dry weather flow source investigations, dry weather microbiological source tracking investigations, coordinating laboratory analyses for water quality constituents of concern, and data analysis and preparation of annual integrated monitoring compliance reports.
