Environmental indicator assessment for smart growth. (20th April 2005) - Roper, William E.
Two of the major environmental indicators evaluated in this study are changes in fragmented forests and increase in impervious surfaces. Both of these indicators have important implications for adverse environmental impact in the county. Satellite imagery and airborne photography were used to collect information on ground characteristics for these two indicators. Change detection analysis of the digital sensor data was conducted over selected time intervals to determine land characteristic changes throughout the county. Study results showed significant changes in the increase in impervious surfaces with annual increases of over 2, 230 acres or just over six acres per day between 2000 and 2001. The data and analysis resulting from this study were used by Loudoun County to assist in the development of land use guidelines, community planning, zoning, and development policy.
