Low Impact Development Techniques Required for the Puget Sound Region
Washington Pollution Control Hearings Board issued a ruling on 8/8/08 requiring that cities and counties around Puget Sound take significantly more aggressive steps to reduce stormwater runoff.
The Board concluded that the permit’s focus on traditional engineered stormwater management facilities like detention ponds was inadequate to protect Puget Sound and meet the law’s requirements. The decision reads,
“The Board concludes that the Phase I Permit fails to require that the municipalities control stormwater discharges to the maximum extent practicable and does not require application of all known, available and reasonable methods to prevent and control pollution, because it fails to require more extensive use of low impact development techniques.”
WWHM3 PRO Basic includes the low impact development (LID) techniques required to meet the Board’s requirements. For more information go to WWHM3 PRO BASIC
