Geospatial analysis for the Urban Forest Sustainability issue was performed similar to what was done for Important Forest Resource Areas and the other issues, which was described in the Overview of Spatial Analysis section of this document. Specifically, weighted raster overlay analysis was performed using thirteen layers to prioritize cities and communities where urban forestry technical assistance should be emphasized. Layers and the weights assigned them are provided in Table 19. Only three layers—Development Threat, Forest to Faucet, and Riparian Areas—from the Southern Forest Land Assessment and other issue analyses were used here. The remaining 10 were built specifically for the urban analysis. Descriptions of these layers and all other layers are provided in the appendix.
Although this analysis was similar to that done for the other issues, there was one significant difference. While all other analyses produced a “wall-to-wall” output layer across the whole state with urban and water areas masked out, the urban analysis was done for cities and communities (2018 US Census Places) and their extraterritorial jurisdictions (ETJs). This allowed for considering the likely future growth zones for each city or community along with area within each one’s respective boundary. Another difference was the use of five quantiles for aggregating the resulting priority index values into classes as opposed to Natural Breaks as done for other issues. In addition, instead of summarizing by county, the urban analysis summarized by place and its ETJ. ETJs were clipped from the final priority-by-place map.
