Description: This feature class contains the geographic bounds and attribute information of wellhead protection overlay districts. These districts are each made through County ordinances and serve to protect an area of 1000 feet surrounding the wells that are listed in each ordinance. The feature class includes the name of the wells that are protected by each district, the zoning change application number, and the ordinance number that each district is approved under.

Description: Created FEMA's flood zone. A field was created called Label_Field in order to symbolize floodway fringe (AE, no floodway), floodway (AE, with floodway) and density floodway (AE, with area of special consideration floodway). Spatial elements representing the boundaries of the flood hazard areas depicted on the Flood Insurance Rate Map (FIRM) are lines. Definition source: FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix L: Guidance for Preparing Draft Digital Data and DFIRM Databases.The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). In addition to the preceding, required text, the Abstract should also describe the projection and coordinate system as well as a general statement about horizontal accuracy.
