SvR provided site planning, civil engineering and green infrastructure services for Kitsap County’s new administration building. The project encompasses a steeply-sloped city block in the heart of Port Orchard. Working collaboratively, SvR, Miller Hull Architects and Site Workshop incorporated sustainable design solutions throughout the project including three green roofs, an innovative rainwater harvesting system, and stream-like water features.
In order to reduce the need for domestic water to irrigate the site’s landscaped areas and green roof, SvR designed a storage and conveyance system for rainwater runoff from the building’s roof. During storm events, runoff is distributed to the site’s five cisterns. Calculations suggest the rainwater harvesting system will ease domestic water demand on-site by 270,000 gallons – approximately half the volume of an Olympic sized swimming pool – cutting irrigation costs nearly in half each year.
