A Five-Year Study of IDDE Data

Pierce County’s Surface Water Management (SWM) division is charged with maintaining both the natural surface water systems and the stormwater collection and conveyance infrastructure within its unincorporated 1,800-square-mile service area (population 380,000). These areas include an impressive variability in landscapes: from glacial streams of Mt. Rainier to fertile farmlands of

When I say “dumbing down,” what I mean is that we (the stormwater profession) are telling engineers to use pre-computer, simple methods and techniques to size stormwater facilities. I recently asked a noted, national stormwater expert this question, and his response was
