Where in Austin are streets with no trees?

In downtown Austin, 59 of 576 street segments, about 4.4 miles in total, have no inventoried street tree within 30 m. Two-thirds of that length is I-35 with its frontage roads and ramps. The rest is short stretches of Baylor St, N Lamar Blvd, Brushy St and a few downtown blocks.

Street	Segments	Length
I-35 main lanes, frontage roads & ramps	29	4.7 km
Baylor St	5	0.49 km
N Lamar Blvd (and its 15th St ramps)	6	0.47 km
Parkway	2	0.25 km
Brushy St	2	0.21 km
Holly St	2	0.12 km
13 other streets (one segment each)	13	0.9 km

The farthest segment, on Enfield Rd, is about 167 m from the nearest inventoried tree. On average, the treeless segments are 88 m from one.

How this was worked out

• We used the City of Austin downtown public street tree inventory (7,295 trees) and City of Austin street centrelines.
• We kept the 576 street segments inside the area the tree inventory covers, then measured the distance from each to the nearest tree. Segments with none within 30 m are counted as treeless.

Limitation: this tree inventory covers downtown only, and it records public trees, not private yards.
