Calf Pasture Pumping Station Complex
Why it's listed
Overlooking Dorchester Bay from Columbia Point, this granite pumping station was built in 1883 as the heart of Boston's new main drainage system. Designed by City Architect George A. Clough, it housed huge steam-driven Leavitt pumping engines that lifted sewage so it could flow to Moon Island and be released with the outgoing tide. The L-shaped building has rough-cut, rock-faced granite walls, a 26-foot round-arch window, and castellated turrets that vented steam. Its heavy proportions and castle-like profile reflect Richardson's Romanesque influence along with medieval-inspired Queen Anne elements. A wing was added in 1905. A gatehouse with filth hoist and a brick west shaft entrance complete the complex. It was the city's first sewage pumping station and the only 19th-century building left on Columbia Point. Windows were bricked in during 1968, and the roof and ironwork have deteriorated, but the original granite is largely intact.
Significance in brief: It was Boston's first sewage pumping station and the keystone of the city's first major comprehensive public sewage system. It is also a good example of Richardsonian Romanesque design with Queen Anne influences, by City Architect George Clough, and it is the only remaining 19th-century building on Columbia Point.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
