Hacienda Green Street Improvements
The project scope included street narrowing, installation of linear parkway serving as stormwater infiltration areas, roadway reconstruction using the Full Depth Reclamation (FDR), installation of 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.

The Person Street Greenscape project consists of a redevelopment of a two-block, quarter-mile stretch of urban street in downtown Fayeteville, North Carolina. The project is part of an ongoing effort to revitalize the downtown core and make its streets friendlier to multiple user modes as well as the environment. The width of the existing road has been reduced to implement a host of LID techniques including permeable pavements, silva cells, filterra units, and bio-infiltration. The previously existing sidewalks have also been widened to create a 10' multi-use path which ties in to local trail systems. The City of Fayetteville partnered with the Department of Biological and Agricultural Engineering at North Carolina State University to help design the layout of the street and the LID systems, and conduct monitoring of water quality following completion of construction. The resulting collaboration provides a great example of what can be achieved by a "green street" project.

Person Street Greenscape and Roundabout
The City of Fayetteville has been working on revitalizing its downtown corridors in stages with added vegetation and street amenities, stormwater treatment facilities, and improved pedestrian, cycling, and parking facilities. The Person Street Greenscape and Roundabout Project is the City's first green infrastructure technology showcase. It has a laundry list of LID BMPs including permeable pavements, bioretentions, Silva Cells, and Filterra units, all within the right of way. The street improvements will also reduce the total impervious area within this three block section of downtown Fayetteville by a projected 13%, and treat and manage more than 85% of the stormwater from the project and offsite for nitrogen and phosphorus before it gets to impaired Blounts Creek. The project will also construct a roundabout and reduce street width on this major downtown corridor, providing traffic calming effects in the busy downtown area.
What we really love about this project is the collaboration between the City of Fayetteville and North Carolina State University's Bio & Agriculture Department, who helped to design the innovative layout AND will be installing monitoring systems for water quality. This means after the project is built we'll be able to get immediate proof of performance information about how well some of these LID systems are working for the City, on a block by block, and dollar for dollar, basis.
Other great features of the project include:

Todd Lane Improvements Pilot Project
This Pilot Project study was completed in 2014 for the City of Austin. As with most Pilot Projects, there is a pretty large gap between the raw score for the project (what we are shown and what is discussed) and what is potentially obtainable based on the scope of work. Todd Lane has a potential with a deliberate effort and low- to no-cost additions to reach that elusive Gold mark (54 points). It would be pretty tough to do this though, especially since the bid administration already was in progress, and a more reasonable target for pursuit of Certification was Bronze.
