The City of Campbell is home to the fifth certified Greenroads Project in Northern California and several firsts for Greenroads. A great before and after story, here are some highlights:
Construction Cost: $4.99 million
Length: 0.9 mi (1.8 lane-miles)
Primary Owner/Design: City of Campbell, CA
Funders/Stakeholders: Federal Transportation Enhancements (TE) grant, California Department of Water Resources
Design Support: Callander Associates
Prime Contractor: Ghilloti Bros (prime)
Subcontractors: Reed & Hanson, Graniterock, Granite Construction, Bortolussi & Watkin, St. Francis Electric, and Chrisp Co.
Functional Class: Minor Collector
Greenroads Version: 1.5
The project scope included will perform street narrowing, installation of linear parkway serving as stormwater infiltration areas, reconstruct roadway using recycle method such as Full Depth Recycling (FDR), install sidewalk infill and dedicated bike lanes.
The City of Campbell started working with Greenroads very early in design and had a great sustainability strategy throughout their first Certification process. Their goals were to reconstruct and restore failed asphalt pavement, improve connectivity between neighborhoods, and encourage more active transportation along the improved linear parkway connecting to Los Gatos Creek County Park and Trail. They started with the environment in mind and explicit goals to minimize long term environmental impacts through low impact development (LID) stormwater features, reducing impervious areas and adding vegetation.
This is also the first project to note specifically a desire to "reduce the roadway carbon footprint" as a performance measure. The average energy consumption and carbon footprint of a roadway (one lane wide, one kilometer long) is about equivalent to that of 100 average American households per year (4 terajoules and 300 MT CO2). Did they do it? Let's see their stats.
