Description: <DIV STYLE="text-align:Left;font-size:12pt"><DIV><P><SPAN>This map estimates the percent land covered by impervious surfaces within 50 meters of hydrologically connected non-coastal waters in each census block group. Impervious surfaces are materials that do not allow the penetration of water and include buildings, roads, and sidewalks.
