During construction, we are concerned with erosion that can contribute excess sediments to the storm drainage system and local creeks. Other pollutants can also be generated at construction sites, such as paints, solvents and concrete slurry.
Dust is also a problem, since it can end up in local waterways.
Construction projects disturbing one acre or more are required to comply with the provisions of the County's Land Grading and Erosion Control Ordinance . Erosion and sediment control standard specifications may be obtained from the County by calling 874-8366. You can also obtain a copy of the checklist used daily by County inspectors to inspect and verify compliance at construction sites. In addition to complying with the County requirements, construction projects in the county disturbing five acres or more need to obtain coverage under the State Water Resources Control Board's general construction stormwater permit . Failure to get a general permit could result in significant daily fines.
