Rank-Ordering Proactive Tree Maintenance for Emergency Response Routing for the City of Austin Urban Forestry Program


Austin parks and recreation department

Austin Parks and Recreation Department

  • The City of Austin Parks and Recreation Department wishes to be proactive and not reactive in the identification and subsequent removal of potential tree hazards from the city of Austin’s roadways. The identification and removal of potential tree hazards will help optimize the cities tree removal services and clear potential hazards for emergency service vehicles.


Purpose

Purpose

  • Generate a comprehensive tree hazard inventory

  • A ranking system will be used to highlight areas with the greatest threat potential in order to prioritize preventative tree maintenance

  • T.E.E.G.S. will accomplish this by utilizing a GIS to analyze the existing tree shade index and identifying areas of high tree density which intersect or overlay with emergency service routes
