US Post Office-Potsdam
Also known as: Potsdam Post Office

Why it's listed
Located at 21 Elm Street in Potsdam, New York, this post office was built in 1932-33 and opened for business on March 6, 1933. The two-story, U-shaped building is clad in yellow brick with limestone trim. Its main facade has a colossal seven-bay recessed portico with fluted Greek Doric columns, reached by granite stairs flanked by cast-iron urns. Funds of $135,000 were appropriated under the Public Buildings Act, and Rosen & Fischel of Chicago served as builder. The design came from the office of James A. Wetmore, Acting Supervising Architect of the Treasury. Most small New York post offices of the era used a Colonial Revival style, so this Classical Revival design is unusual and recalls earlier work by James Knox Taylor, such as the Fulton Post Office. The interior has been heavily altered, though parts of the lobby keep terrazzo floors, marble baseboards and cast-stone walls. The exterior still fits the scale and materials of the nearby Market Street Historic District.
Significance in brief: The nomination argues it is an outstanding example of federal Depression-era public works architecture. It is one of few New York post offices of its period designed in the Classical Revival style, with a colossal Greek Doric portico, rather than the more common Colonial Revival. It also complements nearby buildings in the Market Street Historic District in scale, color and materials.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
