Watershed Assessments

The detailed Watershed Assessments in this part provide specific maps and descriptions on all the subwatersheds within each of the 22 watershed groupings.

Each of the 22 assessments follows the same eight page format. Map 1 shows watershed land use, streams and subwatersheds. Map 2 is actually two maps which compare the average existing and projected imperviousness percentages (the percentage of paved area to overall subwatershed area) for each subwatershed. Map 3 shows rankings of existing stream resource conditions based on biological indicators with a companion table showing details on biological integrity, habitat conditions, and management categories assigned to each subwatershed. Map 4 shows the watershed management categories for each subwatershed and the ranges of projected imperviousness for the watershed based on the actual location by zone. A companion map shows the management categories assigned by subwatershed with a written explanation of the assigned watershed management categories.
