Abstract

Estimates of 2010 impervious cover (New Hampshire) and 2011 impervious cover (Maine) were generated to extend the coverage of previous work in Rockingham and Strafford Counties, New Hampshire, to include all of the Piscataqua Region Estuaries Partnership (PREP) footprint. The newly mapped area comprised the town of Alton in Belknap County, New Hampshire, the towns of Brookfield, Wakefield, and Wolfeboro in Carroll County, New Hampshire, and the towns of Acton, Berwick, Eliot, Kittery, Lebanon, North Berwick, Sanford, Shapleigh, South Berwick, Wells, and York in York County, Maine1. With these new data, standardized, high resolution impervious cover estimates are now available for the entire PREP watershed.

Impervious features covered 3,026 acres (2.7%) in the New Hampshire towns and 13,612 acres (4.9%) in the Maine towns, with a total of 16,637 (4.3%) acres mapped in the entire study area. As expected, the more urbanized towns of Kittery (11.3%), Sanford (7.9%), Eliot (7.0%), and York (6.2%) contained the highest percentage of impervious cover.
