Route 17 Corridor & Gateway
Location: Santa Clara County & City of Campbell
When the Santa Clara Valley Transportation Authority realigned and widened White Oaks Boulevard and Highway 17 from Camden to Hamilton, PGAdesign prepared a tree removal and protection report, as well as PS&E, for the replacement plantings.
PGAdesign focused on protecting large mature redwoods and California pepper trees growing along a slope soon to be partially excavated and replaced with a retaining wall. PGAdesign worked with the engineers to customize the retaining wall, preserve existing trees (saving 45 mature redwoods originally slated for removal), and erosion control. Where trees had to be removed, PGAdesign mitigated the loss with new plantings. The final design provided vegetative cover to the newly cut slopes, absorbed and reduced stormwater runoff, screened the freeway from adjacent residents, filtered freeway dust, buffered noise, and sequestered carbon—a less tangible but important feature to counter the effects of car exhaust on the environment.
