Home My WebLink About_2025-07-09-Doc_Enclave Lot 25_WPCP_signed_v1 (1) (For Select Building Projects Less Than 1 Acre) PURPOSE: This plan can only be used for minor building projects (SFR - new, remodels, additions; and/or commercial remodels). Newly constructed commercial buildings under 2019 CalGreen Codes require the development and implementation of a WPCP similar to the standards of a State submitted SWPPP. This plan is only to serve as a guide, if the applicant elects to use it. The BMPS specified herein shall be considered just the “Minimum BMPs” and during the course of the project additional BMPs (Necessary BMPs) may be required to protect water quality. Please note that an in-fill new single family home project may require additional plan elements. This plan shall be used in accordance with CGP 2009-0009-DWQ, City Stormwater Permit & 2019 CalGreen Building Codes.
