The purpose of this chapter is to protect and enhance the water quality in the city of San Pablo’s watercourses through the implementation of the municipal regional stormwater permit (MRP), as issued by the California Regional Water Quality Control Board (RWQCB) for the San Francisco Bay region in order to comply with the National Pollutant Discharge Elimination System (NPDES) program under the Federal Clean Water Act.
(Ord. 2020-002 § 11 (part), 2020)
The MRP is applicable in all areas of the city on all projects that meet or surpass the development thresholds identified in the most recent iteration of the MRP and detailed in the most recent edition of the Contra Costa Clean Water Program Stormwater C.3 Guidebook. All development within the city must comply with Chapter 8.40 (Stormwater Management and Discharge Control).
(Ord. 2020-002 § 11 (part), 2020)
The city of San Pablo green infrastructure (GI) plan was adopted in May 2019 by resolution of the city council, as required by the MRP 2.0 (RWQCB San Francisco Bay Region MRP Order No. R2-2015-0049, NPDES Permit No. CAS612008). Development of GI facilities within the city of San Pablo, either as a voluntary project feature or as required for projects regulated by Chapter 3 (New Development and Redevelopment) of the MRP, shall refer to the city’s GI plan for guidelines and specifications for GI facilities.

A. 
City feasibility review zone. The “city feasibility review” zones in the city of San Pablo GI plan identify areas within the city in which a city feasibility review is required for the development of GI facilities. Projects located in a city feasibility review zone that are regulated under Chapter 3 (C.3) of the MRP are not exempt from C.3 requirements. On-site compliance with C.3 requirements for projects located in a city feasibility review zone may be required by the city to incorporate special structural elements in order to address local geotechnical conditions and ensure integrity of GI construction. Approval by city engineer is required for on-site development of GI or for an off-site compliance alternative.
B. 
Geotechnically sensitive zone. The “geotechnically sensitive” zone identified in the city of San Pablo GI plan identifies areas within the city in which projects may be prohibited from installing on-site GI due to geotechnical concerns. Projects located in a geotechnically sensitive zone that are regulated under Chapter 3 (C.3) of the MRP are not exempt from C.3 requirements. On-site compliance with C.3 requirements for projects located in a geotechnically sensitive zone may be required by the city to incorporate special structural elements in order to address local geotechnical conditions and ensure integrity of GI construction. Approval by the city engineer is required for on-site development of GI or for an off-site compliance alternative.
