Local Area Management Plan (LAMP)

For Onsite Wastewater Treatment Systems (Septic Systems)

The Draft Local Area Management Program (LAMP) has been prepared to guide the permitting and oversight of Onsite Wastewater Treatment Systems (OWTS, also known as septic systems). This LAMP is produced in accordance with requirements set forth by the State Water Resources Control Board (State Board) in the State OWTS Policy (2013) for County permitting of OWTS.

The purpose of the LAMP is to provide for the continued use of OWTS in Santa Cruz County while providing protection of water quality and public health. Due to historical development patterns, local climate, geology and soils, a majority of the 27,700 existing OWTS could not meet the State Tier 1 Standards for Low Risk systems. However, with appropriate standards and management approaches, systems can be upgraded and utilized to continue to meet housing needs, recharge groundwater basins, and protect water quality. The LAMP is an expansion, refinement, and update of successful wastewater management approaches conducted by Santa Cruz County since 1985.

The initial Draft LAMP was released for public review and comment on December 10, 2019. Comments were received and taken into account during follow up discussion with staff of the Central Coast Regional Water Quality Control Board (Regional Board). A new draft has been prepared and is available through the links below. Comments or questions should be directed to both County Environmental Health and Regional Board staff.  Comments submitted at this time will become part of the record for consideration by the Regional Board. Comments are due December 13, 2020, to be considered in preparation of the final LAMP.

Once review is completed, the final LAMP will be prepared and submitted for approval to the County Board of Supervisors and the Regional Board. Implementation of the LAMP will commence upon Regional Board approval.
