Description:
This dataset was calculated using American Forests’ Tree Equity Score Methodology. 
Tree canopy (2015) and heat severity (2013-2015) data provided by Pima Association of Governments.
Census data (2019 ACS) was obtained using ESRI’s Enrich tool, which estimates census variables on irregular polygons. 

The scores are a metric that informs the city on how well we are delivering equitable tree cover to all our residents. The score combines "measures of tree canopy cover need and priority for trees in urban neighborhoods. It is derived from tree canopy cover, climate, demographic and socioeconomic data." (American Forests, 2020) 

Definitions: 
Tree Equity Score (0-100): A score of 100 means tree equity has been achieved in this neighborhood. Lower scores indicate neighborhoods in greatest need of improved canopy. This metric is only calculated in populated neighborhoods. 

Priority Index (0-1): Higher scores indicate higher vulnerability. Includes 5 equally weighted variables: 
Purpose 
This layer was developed to assist the Green Stormwater Infrastructure identify vulnerable neighborhoods and focus GSI projects in those neighborhoods.
