14th Avenue streetscape Improvements, Oakland

The City of Oakland hired Sandis to provide engineering and beautification services along 14th Avenue, spanning 18 blocks from 12th Street through 27th Street. The four-lane streetscape improvements included traffic signalization (at four intersections), roadway restriping, a reworking of sidewalks, new bulbouts and street trees, improvements to bring ADA ramps up to code, adjustment/realignment of bus stop locations, widening and roadway realignment at one intersection, minor storm drain improvements, and the conversion of existing medians to planted medians along 14th Avenue, spanning 18 blocks from 12th Street through 27th Street.

Beautification efforts included the installation of shade-providing street trees (lowering heat island effect and reducing greenhouse gas), improvements to medians including new street trees, the addition of no-mow turf areas in localized sites, identification and layout of bicycles routes, use of structural soil at street trees (to increase soil volume for the trees while supporting the sidewalk), use of non-chemical soil amendments and non-chemical weed barrier (cardboard sheet mulching).
