Council approves code changes to require repair of failed sewer laterals, dissolves offset program

San Luis Obispo — The City Council voted to amend Title 13 of the municipal code on April 19, 2026, directing a new mandatory approach for private sewer laterals identified in poor or failed condition and ending the city’s mandatory wastewater flow offset program.

Under the ordinance changes approved 3–0 (Mayor Erica A. Stewart recused; one absence), property owners whose private sewer lateral is determined by a city inspection to be in “poor” or “failed” condition will be required to replace the lateral within 180 days of issuance of a Notice to Correct. The code amendment includes director discretion to grant time extensions when property owners demonstrate a good‑faith inability to complete work within the deadline.

Council also voted to dissolve the 2019 wastewater flow offset program that required certain new or intensified development in capacity‑constrained parts of the city to secure offsets by funding or performing lateral replacements elsewhere. Staff told the council they estimate that 90–95% of projects would no longer require offset actions under the new approach. Instead, moderate and major development proposals in modeled, capacity‑constrained areas will be evaluated on a case‑by‑case basis using the city’s updated hydraulic wastewater model; only projects shown by modeling to create capacity concerns will receive conditioned mitigation requirements.

Why the change: Staff and many representatives of the development and realtor communities told the council the offset program had proven difficult to administer and to match offsets to projects. Deputy Director of Wastewater Chris Leman said the city’s long‑range model (updated in late 2025) gives staff the ability to identify which projects actually require mitigation and to tailor conditions, rather than the blanket offset requirement that had been in place since 2019.

Rebates and transition: Staff described existing and expanded rebate tools to limit the financial impact on property owners. The city currently offers a $350 inspection rebate for camera/video inspections in capacity‑constrained areas and a $4,000 replacement rebate that applies citywide to single‑family homes and was expanded to multifamily and commercial properties in constrained zones. Staff said roughly 369 inspection‑upon‑sale results have been classified as poor or failed (about 116 of those in constrained areas); 114 laterals have been replaced through the offset program since 2019 and roughly 518 replacements have occurred voluntarily with rebate support.

Timing and implementation: To allow outreach, clarification of procedures and contractor coordination, staff recommended and the council set the effective date for the new mandatory replacement requirement to be Jan. 1, 2027. For projects currently in the pipeline, staff recommended authority be given to the Public Works and Utilities Director to waive pending offset improvement requirements while the program transitions.

Council reaction: Councilmembers expressed concern about implementation logistics, contractor availability and how rebate checks would be disbursed in real‑estate transactions. Councilmember Shoresman, who moved the motion, said the 180‑day compliance window and director discretion should provide practical flexibility during rollout. Realtor and developer groups in public comment largely supported dissolving the offsets while urging targeted mitigation in constrained areas.

What happens now: Property transfers that trigger inspection requirements will continue to require camera inspections. For laterals found in poor or failed condition, the city will issue the Notice to Correct and the 180‑day clock will begin. Property owners who complete qualifying replacements can apply for the rebate, which staff said is issued to the current owner at the time the rebate is awarded (that may be the seller or buyer depending on timing). For larger development projects, discretionary, model‑based mitigation requirements may still be imposed where modeling shows a capacity shortfall.

The council’s vote amends the municipal code to require the replacements, expands the practical use of rebates, dissolves the mandatory offset program and directs staff to continue outreach and to help transition projects already in process.
