JRA Runoff Calculation

The James River Association has a website that allows residents of the James River Watershed to calculate the water run off of their properties. The website asks a series of questions about the size of the lot, the land use type, the percent cover of roofs, impervious surfaces and  open space. It also takes into account if water spouts or green roofs are in place. The site then generates a report telling the user about their lot, amount of runoff, ways to mitigate their impact and use their rainwater.
