Offsite Stormwater Alternative Compliance Program for Meeting New Development Requirements

Technical Advisory Committee

The Municipal Permit provides Offsite Alternative Compliance, as an option for Priority Development Projects in lieu of implementing onsite structural best management practices to comply with pollutant control and hydromodification management requirements. The City will implement the alternative compliance program in two phases:

  • Phase I: Applicant Implemented Alternative Compliance Projects where the project applicant would propose an offsite alternative compliance project and be fully responsible for the project’s design, construction, operation, and long-term maintenance. Phase I implementation coincides with Feb. 16, 2016, the effective date of the Stormwater Standards Manual Update.
  • Phase II: Independent Alternative Compliance Projects includes another option, a credit trading system. This phase is currently in the initial planning stage.

Stormwater Ordinance Amendment and Minimum Best Management Practices

Current and Existing Development

The City is required to amend its Stormwater Management and Discharge Control Ordinance per PDF icon San Diego Municipal Code Section 43.03 to conform to the requirements of the  PDF icon 2013 Municipal Separate Storm Sewer System (MS4) Permit Order R9-2013-0001 issued by the San Diego Regional Water Quality Control Board. The amendments include updates to the list of non-storm water discharges (including conditions for the discharges) allowed into the City's storm drain system. The amended list is consistent with the list from the 2013 MS4 Permit. Each of the discharges described in the ordinance require minimum best management practices (BMPs) before they are deemed allowable into the storm drain system. BMPs are required implementation activities to prevent pollution from leaving a property and entering the storm drain system. Public information sessions about the draft Ordinance and Minimum BMPs were held in January 2015. Public comments received following these meetings were reviewed and incorporated into the documents below, as appropriate.
