The results of this technique are show here on the left, for the
town of Old Saybrook, CT. Estimates of % impervious cover are averaged
by local watershed (thick black lines), and depicted in the “stoplight”
color scheme shown on the key. |

This current snapshot can be compared with a zoning-based build-out
analysis, which estimates future imperviousness based on zoning
designations. The same technique is used, except that imperviousness
land cover/land use coefficients are applied not to the remote
sensing-based land cover, but to zoning categories (i.e., all
rural residential, 2 acre areas will have x % of impervious surface). |
