Purpose Statement To update the City of Austin Urban Forestry Program on the progress of Austin Canopy and Water Quality towards the completion of the Austin Tree-Canopy Resource, Phase II Project.

The City of Austin’s Urban Forestry Program approached ACWQ seeking information about the relationship between tree canopy and the water quality of creeks within the greater Austin area. Background

 The objective of ACWQ is to determine the percentage of tree canopy coverage within the stream reach buffers.  Create a tool  Time permitting, clip datasets Project Description

 Initial Research  Table 1  Distribution of tree canopy coverage  We have determined stream flow direction  We have established a website template Work Completed

Proposed Timeline

Current Timeline

Overall the progress of the team has slowed as further clarification is needed on several issues. Once feedback is provided, the team is confident that we will be able to move forward and complete the project by the May 4 th deadline. Summary
