United States Forest Service Building, Art Deco federal building in Ogden, United States.

The United States Forest Service Building is a four-story Art Deco structure at 507 25th Street, clad in eight shades of brick that darken from beige at the top to tan at the base. Its rectangular lower floors give way to a U-shaped light court on stories two through four, and the facade carries terra-cotta spandrels with projecting vertical apexes.

The building was constructed between 1933 and 1934 using New Deal funding to fight the Great Depression. This investment in public construction projects provided work for many laborers during this economically difficult period.

A Utah historical marker in the main lobby notes the building's place among Ogden's Art Deco structures. The Forest Service has kept offices here since the 1930s, now joined by the IRS and the USDA Office of General Counsel, and the Ogden Ranger District and Intermountain Research Station staff still work in the building.

The building stands at 507 25th Street, on the southeast corner of 25th Street and Adams Avenue, within the Ogden Central Bench Historic District. It still houses Forest Service, IRS and USDA offices, so interior access is limited; the facade facing 25th Street is the one to study from the sidewalk.

The building's granite foundation comes from the Raymond Granite quarry in California, and a terra-cotta water table with a matching gray glaze tops it. The architects chose eight brick shades and supervised their placement themselves to achieve the color gradation.
