Poor sidewalk tree pits. The tiny patches of dirt that give rise to Pike/Pine’s tree-lined blocks are often ignored receptacles of urban waste until cursed at for tripping up hurried pedestrians.
Now some of those Pike/Pine dirt patches are getting an upgrade. The Seattle Department of Transportation has started installing “flexible porous pavementâ over 19 tree pits along E Pike between Broadway and 12th Ave. The goal of the project is to improve pedestrian safety by smoothing over the sidewalk surface while offering greater protection to E Pike’s trees. SDOT promises no trees will be harmed in the installation.
An SDOT flyer about the project says, âthis innovative solution is one of several efforts to expand our use of these new materials as an alternative to traditional mulches and tree grates.â The permeable pavement also requires significantly less maintenance work.
All sidewalks will remain open during the project. Contractors may take up a few parking spots during the installation, which is expected to wrap-up May 6th. The project is one of the many funded by the $930 million Move Seattle levy, approved by voters last year. CHS previously looked at some of the other levy-powered Council District 3 projects.
Even with healthier reinforced bases, many urban trees will be chopped down before their time. In 2014, Broadway’s big, old tree had to go after it began leaning too far over the sidewalk. A potentially “exceptional” red cedar is also on track to come down to make way for a new development at 19th and Mercer.
