The County’s Stormwater Program is pleased to provide an updated Post-Construction Stormwater Guidebook for new and redevelopment projects within the County’s Phase II Municipal Stormwater Management Areas. The Post-Construction Stormwater Guidebook replaces the County’s LID Handbook, which was initially released in 2014.

The Guidebook serves as a guidance document that communicates the County’s expectations for post-construction stormwater management and strategies that meet the Central Coast Region Post-Construction Stormwater Requirements. The Central Coast Region Post-Construction Stormwater Requirements prevail as the authority on design standards that the County is required to enforce.

Incorporated cities within in the Central Coast Region are welcomed to adopt the strategies, forms and templates included in the Guidebook and this page at their discretion. Please note: the County’s authority for plan check is limited to unincorporated areas and the County is not affiliated or involved with plan reviews or code interpretations made by separate permitting jurisdictions.
