Agency Approvals

Before your Sewer Area Study can be approved you may need to approach various jurisdictional agencies to obtain peak discharge Q or outlet approval depending on the boundary of the sewer shed. Lastly, Los Angeles County Sanitation District Will Serve Letter is always required as part of the approval package.

What happens after Sewer Area Study Approval?

Depending on which entitlement you’re trying to get approval for, the approved sewer area study will determine if there will be mitigation or not. You may need to submit a sewer plan as part of your development or improvements of the existing sewers to have a better capacity. The findings on the approved report will be the basis on proper design of the sewer system.
The approved sewer area study shall be invalidated should there be an increase in the total number of dwelling units, an increase in the density, a change in the proposed sewer alignment, an increase in the tributary sewershed, a change in the sewer connection points, or the adoption of a land use plan or a revision to the current plan. A revision to the approved sewer area study may be allowed at the discretion of the Director of Public Works. The approved sewer area study shall remain valid for two years from the date of sewer area study approval. After this period of time, an update of the area study shall be submitted by the applicant if determined to be warranted by Public Works.
