PRIORITIZED PLANTING ANALYSIS
Social Equity Factors
Urban Heat Island Reduction
Prioritized Planting Map Now Available A prioritized planting analysis was conducted to identify areas of the city most in need of canopy cover based on city and community priorities. The analysis used a social equity analysis (see page 17), along with urban heat island and stormwater factors, to determine priority areas to plant trees. From this analysis, more than 600,000 potential tree planting sites were identified in Columbus. Over 65% of potential planting sites are located on private property and 35% on City-owned property. The City and its partners can use this data set as a starting point to identify areas for tree planting. However, it is necessary to field verify for tree planting suitability as these sites were determined using a model.
Notes on Planting Map
Stormwater Benefits
1. Sites were identified using 2015 Urban Tree Canopy land cover data and aerial imagery 2. Tree spacing was based on planting in a landscape setting. 3. Sites are potential planting locations, however, not all sites identified will be suitable for tree planting. Field verification of potential planting sites will be required. 4. This analysis can be rerun once an updated canopy assessment is completed.
Figure 4.16 | Priority Planting Map in ArcGIS The data for the priority planting map is accessed and edited in ArcGIS. ▲ Figure 4.17 | Prioritized Planting Components The priority planting map is composed of three factors: a social equity index, urban heat island temperatures and stormwater needs. The composite of these three factors is shown in Map 4.3. ◄
