Post-Construction Stormwater Guidebook


The County’s Department of Public Works and Department of Planning & Building are updating the County’s Low Impact Development Handbook. The Low Impact Development (LID) Handbook was first published in 2014 to support project developers with integration of the Central Coast Post-Construction Stormwater Requirements (Resolution R3-2013-0032).

The updated Post-Construction Stormwater Guidebook will serve as the guidance document that communicates the County’s expectations for post-construction stormwater management and strategies that meet the Central Coast Post-Construction design requirements. Once completed, the new Post-Construction Guidebook will replace the existing Low Impact Development Handbook.

The update effort includes the release of a Preliminary Draft and Final Draft versions for public comment. The final adopted Guidebook is expected to be released in 2024. The County will host a public webinar in conjunction with the launch of the completed Guidebook.

County staff welcome your questions and comments on this update process via email to [email protected]
