Appendix | ENVISION FRANKLIN 145 The land suitability analysis was performed using the CommunityViz software plugin for ArcGIS and data sets provided by the City of Franklin. Relative suitability was calculated for 11 individual suitability factors. These factors were then weighted to calculate an overall suitability score for each parcel in the City of Franklin Urban Growth Boundary. Suitability scores are calculated as a number between 0 and 100 with higher scores representing greater development suitability. The suitability scores are relative, and it is important to keep in mind that parcels with low suitability scores may not or should not be considered totally undevelopable. It may be that a large portion of the site is undevelopable but not the whole site. Also, as utility infrastructure is extended and roadways are constructed or improved, development suitability may change. APPENDIX B: DEVELOPMENT SUITABILITY ANALYSIS SUITABILITY FACTORS The nine suitability factors used in the analysis are: FACTOR DESCRIPTION Floodway and Floodplain Special Flood Hazard Areas defined as the area to be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year (Zones A and AE). Hillsides and Hilltops Defined as areas included in the Hillside/Hillcrest Overlay (HHO) District. Fires Stations Location of current fire stations as listed on the City of Franklin’s official website. Sewer Service Existing water and sewer lines as provided by the City of Franklin. Employment Center Defined as the McEwen character area. Commercial Centers Groups of non-office commercial land use as determined by the “GLU” designation on the “PARCELSLCS” shapefile. Riparian Buffers Areas included within a 60-foot buffer on either side of water resources using GIS data from the USGS National Hydrography Dataset. Primary Thoroughfares Interstate 65, SR 96/Murfreesboro Road, and Mack Hatcher Parkway Secondary Thoroughfares Thoroughfares with access to Interstate 65 (Moores Lane, Cool Springs Blvd., McEwen Drive, Peytonsville Road/Goose Creek Bypass) Parks Location of city and county parks as provided by the City of Franklin. Trails Location of multi-use paths as provided by the City of Franklin. FACTOR TYPE Two types of factors were used in the analysis. The first type is proximity based; the closer the parcel is to the target area for each factor (i.e. commercial center, thoroughfare, fire station), the higher the suitability score. The second type of factor is overlay based. For these factors, the amount of overlap between the parcel and the target area (i.e. floodplain, hillside) is calculated. For example, parcels with higher amounts of overlap with hillsides and hilltops result in lower suitability scores.
