Impervious Surfaces

Impervious surfaces associated with the “built environment,” like asphalt, roofing and cement, disrupt the water cycle and are widely accepted as a reliable indicator of urbanization and its impacts on natural resources, particularly water resources. CLEAR researchers have developed several ways to estimate and measure impervious surfaces, in support of their outreach programs for local land use officials; all of these techniques are described in the NEMO Program Impervious Surface website. The impervious surface model uses the land cover data from the first phase of Connecticut’s Changing Landscape, in combination with advanced remote sensing analytical techniques, to assess the amount of these materials.

This work is partially funded by the Long Island Sound Study, a National Estuary Program that is a collaboration of the federal EPA and the states of Connecticut and New York.
