This increase in runoff volume is likely to only occur in the George Watch Lake Watershed because the storm water management plan establishes a drainage system that routes nearly all runoff from the site to the east and into the George Watch Lake Watershed. Runoff from impervious surfaces that are within the Marshan Lake Shoreland District is directed to a series of infiltration basins/ponds that eventually outlets to a wetland, which is tributary to another extensive wetland complex located in the George Watch Lake watershed. Therefore, the increase in runoff volume from the site will have no net effect on the Marshan Lake Watershed and Shoreland District.
