Foothill Retarding Basins Operations and Maintenance Manual

PlaceWorks prepared a mitigated negative declaration for OC Public Works’ manual for operation and maintenance of nine retarding basins in the foothills of the Santa Ana Mountains. Sensitive species and habitats in several of the basins include riparian and coastal sage scrub habitats and least Bell’s vireo, a federal and state endangered species. We provided a biological resources assessment and botanical survey of the nine project sites in addition to CEQA documentation.
