UTRI Data Process and GIS Tool Description
Complete narrative discussion of UTRI that includes: an overview, GIS approach and data, the model "step-by-step" table, additional processing notes, and raster calculator hints for implementation.
The objective of the Urban Tree Risk Index model (UTRI) is to prioritize street segments of a community for more detailed (comprehensive or intense) risk assessment, mitigation, and management. In addition, the UTRI and resulting urban tree risk management is a critical component in the Vegetation Risk Management Plan.
CARPDC has developed a relatively simple GIS approach to rank areas of the community for their likely risk to infrastructure and human life in the event of a natural disaster (e.g. hurricanes, ice storms, straight-line winds) based on the publication Urban Tree Risk Management: A Community Guide to Program Design (Pokorny, NA-TP-03-03, 2003)
