California Natural Resources Agency Headquarters in Sacramento

Tetra Tech’s High Performance Buildings Group is currently providing mechanical, electrical, plumbing, energy analysis, and commissioning for a new, modern office building in Sacramento for the State of California Department of General Services.


  • Size: 838,000 square feet
  • Construction Cost: $598 million
  • Client/Owner: State of California Department of General Services
  • Architect: AC Martin
  • Contractor: Turner Construction
  • Completion Date: 2021

The P Street Building will serve as the new 20-story, 838,000-square-foot headquarters for the Department of Natural Resources. The tower, which will encompass a 300-seat auditorium, will be the workplace of 3,500 state employees.

The most defining characteristic of the development will be its achievements as a sustainable building. The property is designed to meet LEED Platinum and zero-net energy standards. Tetra Tech designed energy-efficiency and water-efficiency features such as radiant floor heating and chilled beams, as well as reclaimed water systems. The building will perform at an energy use intensity of no more than 30 kilo-British thermal units (kBtu) per square foot per year and use at least 50 percent less water than a typical, comparable office building.

The building will operate using 100 percent solar energy. This is part of a first-of-its-kind agreement with the Sacramento Municipal Utility District in which California’s Sacramento portfolio will move toward solar power.

As part of the overall project, the Department of General Services will make some exterior improvements to the historic Heilbron house, which will remain on site.

The project also includes construction of a childcare facility to accommodate 120 children. Enabled by Senate Bill 401, this will be the largest childcare facility constructed by the state. A single level of below-grade parking will provide approximately 50 spaces for agency vehicles.
