STORM DRAINAGE DEVELOPMENT STANDARDS & EROSION CONTROL

Storm Water Post Construction Standards (1.2 MiB)

The City Council of the City of Watsonville enacted new post construction requirements for managing storm runoff from new development and redevelopment projects.  These were approved January 28, 2014 and the ordinance and the new Post Construction Requirements improvement standard became effective February 27, 2014.  The  new regulations closely follow the requirements adopted by the Central Coast Regional Water Quality Control Board July 12, 2013.   If you have comments or questions regarding the Post Construction Requirements, please contact Tom Sharp at 831-768-3076

A Homeowners Guide to Greening Stormwater Runoff (7.1 MiB)
