2002 Comprehensive Stormwater Implementation Program Plan

In March of 2002, staff completed a well-written, comprehensive document describing a wide array of successful projects accomplished under a grant received from the WA Dept. of Ecology's Centennial Clean Water Fund.  This report identified components of a comprehensive stormwater program, including elements to be identified under the upcoming NPDES Phase II permitting.
