Offset Requirements:

Approved by the City Council in September 2019, the Wastewater Flow Offset Program was developed to accommodate new or intensified development in capacity constrained areas by replacing laterals in poor condition. Capacity constrained areas are areas the City where the existing sewer system infrastructure (pipelines) cannot accommodate additional wastewater flow. These areas are identified in the City’s General Plan Water and Wastewater Management Element.

The Wastewater Flow Offset Program requires all new development to replace existing sewer laterals in the same capacity constrained area to offset the additional wastewater generated by the project. The number of lateral replacements is based on the size of the residential unit(s) or commercial space proposed to be added on a property.

The Sewer Lateral Portal is a resource for locating sewer laterals within capacity constrained areas that need replacement.
