Post-Construction Stormwater Management Ordinance

Consistent with the recommendations outlined within the recently approved Walnut Creek Watershed Master Plan, the City has recently revised its Postconstruction Stormwater Management Ordinance and adopted the Clive Stormwater Management Manual.  The new postconstruction stormwater management regulations are focused on maintaining or restoring stable hydrology in the receiving waters by ensuring that the developed site mimics the natural hydrology of the pre-development site.  These new regulations look at several stormwater impacts (volume, rate, duration, frequency) rather than being solely focused on rate control.
