Impervious Surface Analysis for NEMO Program
Funded by Minnesota Sea Grant and the Center for Community and Regional Research.
September 2003 - July 2004.
Jesse Schomberg (MN Sea Grant), Stacey Stark (Geography), Mark White (NRRI)
This project will prepare the impervious surface calculations to implement the NEMO (Nonpoint Education for Municipal Officials) program in many communities in the Minnesota Lake Superior basin. The quantity of impervious surface in a watershed is an effective indicator of water quality, and its calculation is one of the most time-intensive steps in NEMO. This project will provide an assessment of four different procedures for obtaining impervious surfaces using aerial photography and Geographic Information Systems technology, will compare the accuracy and efficiency of each, and use the most accurate to calculate current impervious surface amounts for the coastal zone region. The mapping of impervious surfaces on a regional basis will reduce both the cost and the time required to bring the NEMO program to all communities in this region. The result of this project will make NEMO available to all interested communities in this region, and allow them to identify potential surface and ground water quality hazards in various development scenarios.
