The 141,000-square-foot William Jack Hernandez Sport Fish Hatchery in Anchorage, Alaska, uses 95% less water and energy than conventional hatcheries.

Designed by HDR Inc. on a former military brownfield site, the hatchery is the first completed project to be assessed using the Institute of Sustainable Infrastructure's rating system. It incorporates many of the 60 elements that comprise Envision's checklist and earned a Gold rating by:

  • Forming a partnership to transfer waste from hatchery operations as input to another facility
  • Repurposing existing water and sewer infrastructure
  • Creating connections to existing bike trails and adding a trail through a park-like setting while clarifying traffic flow and protecting a stream
  • Providing wayfinding and educational signage
  • Piloting and then implemending a recirculated aquaculture system that reduced the energy needed to heat  process water, ventilation, and building heating by 88%
  • Lowering pesticide and fertilizer impacts with landscaping with native plant species.

ISI was founded several years ago by the American Society of Civil Engineers, American Council of Engineering Companies, American Public Works Association, and the Zofnass
Program for Sustainable Infrastructure at Harvard University Graduate School of Design.
