San Diego County’s Final 2025 Local Agency Management Program changed how homeowners should think about permits, setbacks, and system limits. Joseph Bartkowski, founder of Solid State Septic in Ramona, walks owners through what the updated LAMP means in practice.
The County Board of Supervisors approved the updated program, and San Diego Water Board Resolution R9-2024-0130 approved the County LAMP for regulating OWTS, with the Final 2025 LAMP effective February 1, 2025. The points below draw on the County septic program page, that LAMP, the resolution, State OWTS Policy context, and EPA septic education.
Know Why the 2025 LAMP Matters Locally
A LAMP lets the County apply alternative standards to the statewide OWTS Policy while still protecting water quality and public health. Joseph Bartkowski stresses that owners should use the County document—not informal contractor lore—as the baseline.
- Read the Final 2025 LAMP summary of changes alongside the full program text.
- Confirm whether a planned repair or replacement is reviewed under the new standards.
- Keep links to DEHQ applications with the property’s permit file.
San Diego County’s San Diego County DEHQ Septic Systems page hosts the Final 2025 LAMP effective February 1, 2025, and San Diego Water Board Resolution R9-2024-0130 is the regional approval that authorized the County to implement that program under the statewide OWTS Policy.
Expect Tighter Flow and Siting Expectations
Updated local standards affect new and replacement systems, including flow thresholds and setbacks that protect surface water and groundwater. Sites that passed under older practices may need redesign today.
- Ask whether proposed daily flow sits within current LAMP limits for the project type.
- Verify horizontal setbacks to water bodies and wells early in planning.
- Budget for slope stability or groundwater evaluation when DEHQ requires it.
The Final 2025 LAMP sets the County’s detailed siting, design, and operating standards, while California’s State Water Board OWTS Policy remains the statewide policy framework that local agency management programs must still satisfy.
Use DEHQ Applications Before Construction Starts
Installation permits, repair authorizations, and related forms are how DEHQ reviews designs and tracks work. Starting excavation without authorization risks stop-work orders and incomplete records.
- File the correct DEHQ application for new work, modifications, or repairs.
- Submit layouts and supporting data that match LAMP technical expectations.
- Schedule required inspections before covering tanks or dispersal components.
DEHQ’s San Diego County DEHQ Septic Systems applications and program services implement the County LAMP day to day, and EPA’s EPA Septic Systems homeowner guidance reinforces that proper design, installation, and maintenance prevent premature failure.
Keep Operating Records After Approval
Approval is not the end of compliance. Standard systems still need pumping and solids control, and systems with supplemental treatment carry additional operating-permit and monitoring duties.
- Retain pumping invoices and inspection notes for the LAMP retention period.
- Update the property file when components or service providers change.
- Ask DEHQ which operating plan applies before assuming a three-year rule of thumb.
The Final 2025 LAMP describes operation, maintenance, and recordkeeping expectations that owners and service providers share, and Resolution R9-2024-0130 directs the County to implement that approved LAMP consistent with the OWTS Policy.
