14.48.050 - Stormwater Management Manual for Western Washington adopted.

The minimum requirements of the 2005 Edition of Ecology's Stormwater Management Manual for Western Washington are adopted by reference for the Allyn and Belfair urban growth areas (UGA's) and other areas as defined or added pursuant to Chapter 14.46. As the boundaries of the Mason County stormwater utility are amended to include additional area, the minimum requirements of the 2005 manual shall apply to those additional areas. For information about the utility boundaries, responsibilities, and financial management see Chapter 14.46.

In addition to the minimum requirements of the 2005 manual, for new development and redevelopment, no additional stormwater runoff shall be allowed from the property due to added impervious surfaces or disturbed land. The stormwater runoff from new impervious surfaces or disturbed land shall be treated and prevented from flowing off the property being developed.
