This report is one of ten volumes that make up the Sourcebook for Local Water Resources Management, which provides a wide range of information to assist localities in Virginia. The compendium was produced by a team from the College of Architecture and Urban Studies at Virginia Tech with a grant from the Virginia Environmental Endowment (VEE). The objective of the project is to help localities develop the means to respond to local water-related problems and to incorporate water resources information into land use and comprehensive planning.
