Anne Arundel County Impervious Areas Our “greatest challenge” is restoration of those areas developed in an era when storm water management was non-existent or much less than it is today... Historical Urbanization vs. New Development

Severn River Watershed Impervious Cover Landcover Acres Impervious Acres Impervious % of Landcover % of Total Impervious Commercial (Private Lands) 1,9711, %16 % Industrial (Private Lands) %4 % Residential (Private Lands) 16,3324,00124 %43 % Gov’t Owned (Public Lands) 10,2192,95629 %32 % Other (Private Lands) 15, %5 % Total44,3539,29021 %100 %

Severn River Watershed Total Nutrient Loads from Stormwater and Septics Total Nitrogen (TN) TN (lbs/yr) - Existing TN (lbs/yr) - Buildout % Increase Total Phosphorous (TP) TP (lbs/yr) - Existing TP (lbs/yr) - Buildout % Increase = 449,629 = 490,257 = 9 % = 25,594 = 27,117 = 6 %
