To quell the frustration and annoyance of traffic in the Phoenix area, the city of Glendale built a new park-and-ride facility across the street from the Arizona Cardinals' football stadium. The city's goal was to use as much of the available space as possible and do so in an environmentally friendly way.
Glendale wanted to keep costs low and explore using pervious concrete as a sustainable stormwater management solution. At the time of bidding, Progressive Concrete Works was the only Arizona-based company with experience installing pervious concrete.
The contractor installed 144,000 square feet of its trademark DrainScape pervious concrete as the primary paving system at the facility, making it the largest installation of pervious concrete in the Southwest. Pervious concrete provides first-flush pollution mitigation by eliminating runoff and directing surface water into the subgrade below, where it recharges groundwater aquifers beneath the site. Pervious concrete also reduces the lot's urban heat island effect.
DrainScape's mix design allows for a 15% to 30% void structure, through which up to eight gallons of water per square foot can pass through in a minute. USGBC's LEED program recognizes it as integrating paving and drainage to manage onsite stormwater, thereby allowing a smaller development footprint.
In 2008, the Glendale Park & Ride earned a Grand Award from the American Council of Engineering Companies of Arizona and was named the Best 2008 Concrete project by Southwest Contractor magazine.
