The project includes office space for 400 employees and combined maintenance and storage facilities for over 500 municipal service vehicles.

This facility receives several community visitors on a daily basis and it was a goal of City leaders to showcase innovative and energy efficient design. For instance, storm water management is handled through infiltration processes within bio-retention cells dispersed among the parking area. These cells include a free draining soil medium and native plantings to help remove silt and harmful chemicals before the rain water leaves the site.

Project Features
• LEED Silver
• Bio-retention cells
• Native landscaping
• Entry plaza and courtyard
• Floodplain management

Being within the McCleod Run watershed, special consideration was taken to minimize the impacts this urban site would have on our water systems and the overall environment.

Mitigating storm water run-off and increase on-site infiltration, required several storm water management practices to be incorporated across the entire site. Curb cuts leading into abio-swale island captured substantial runoff contaminants from the parking lot. Another bioretention area near the front entrance managed site run-off from the south half of the parking area, the surrounding lawn is graded into a filtration cell. The rear parking lot uses porous concrete within the parking stalls to remove pollutants coming from vehicles and the surrounding site.

Native forbs and grasses keep maintenance low and provide visual interest throughout the season.
