The impairment of the tax base.(B) These provisions are designed to accomplish the above purposes by:1. Regulating uses, activities, and development which, acting alone or in combination with other existing or future uses, activities, and development, will cause unacceptable increases in flood heights, velocities, and frequencies;2. Restricting or prohibiting certain uses, activities, and development from locating within areas subject to flooding;3. Requiring all those uses, activities, and developments that do occur in flood-prone areas to be protected and/or floodproofed against flooding and flood damage;4.

School Districts is a polygon feature used to denote the district boundaries of Elementary Schools in the County of Roanoke.School Districts are maintained within the Administration Feature and is dissolved out weekly.Administration is a polygon feature consisting of the smallest statistical areas bounded by visible features such as roads, streams, railroad tracks, and mountain ridges, as well as by non-visible boundaries such as jurisdictional limits, school district, public safety boundaries, voting precincts, and census blocks. This methodology allows for single stream editing to move coincidental boundaries across many aggregate datasets simultaneously. Administration is maintained though an ArcGIS topology class in conjunction with County Parcels and Zoning. The topology prevents self-intersection and gaps, while ensuring complete coverage among the participating features.
