Local Agency Management Program (LAMP)
The Local Agency Management Program (LAMP) develops minimum standards for the treatment and disposal of sewage through onsite wastewater treatment systems. The LAMP is the culmination of the actions required by Assembly Bill 885 and the State Water Resources Control Board to develop regulations and standards for onsite wastewater treatment systems. The County of San Luis Obispo LAMP is designed to protect surface water and groundwater from contamination while providing flexibility in design criteria in consideration of local conditions.
Design Requirements for New & Replacement Septic Systems:
The County has created a Local Agency Management Program (LAMP)
The complete Tier 1 standards are contained within the State OWTS Policy.
Additional information is available at the California Central Coast Water Board site.
Subdivision Parcel Size Requirements:
LAMP standards also include requirements for minimum subdivision parcel size for parcels served by septic systems. The minimum parcel size for septic systems and community water is based upon average annual rainfall. Updated rainfall data is available online for review on the County of San Luis Obispo LandUseView application. The minimum parcel size for Onsite Wastewater Treatment Systems and onsite well is 2.5 acres. Planning area standards, zoning standards, and other requirements also apply.

The Local Agency Management Program (LAMP) is the culmination of the actions required by Assembly Bill 885 (AB 885) which directed the State Water Resources Control Board (SWRCB) to develop regulations or standards for onsite wastewater treatment systems (Septic Treatment Systems) to be implemented by qualified local agencies. The SWRCB adopted the Water Quality Control Policy for Siting, Design, Operation, and Maintenance of Onsite Wastewater Treatment Systems on June 19, 2012 (OWTS Policy). The OWTS Policy allows local agencies, such as the County of San Luis Obispo, to permit and approve Septic Treatment Systems, based on a local ordinance, after approval of a LAMP by the Central Coast Regional Water Quality Control Board (Central Coast Water Board).
The County of San Luis Obispo LAMP is designed to protect groundwater sources and surface water bodies from contamination through the proper design, placement, installation, maintenance, and assessment of individual Septic Treatment Systems.
The LAMP develops minimum standards for the treatment and ultimate disposal of sewage though the use of Septic Treatment Systems in non-sewered unincorporated areas of San Luis Obispo County. The LAMP will also expand the ability of Planning & Building to permit and regulate alternative Septic Treatment Systems while protecting water quality and public health.
