General Information

1.0 Background

United States Department of Agriculture, Agricultural Research Service (USDA-ARS) operates the Beltsville Agricultural Research Center (BARC) in Beltsville, Maryland. BARC is considered an historic district and is eligible for inclusion in the National Register of Historic Places (NRHP). USDA-ARS intends, per USDA-ARS’s obligation to dispose of surplus property in compliance with the 2015 Reduce the Footprint Policy (Executive Office of the President, Office of Management and Budget, 2015), to demolish 14 buildings that contribute to the NRHP-eligible historic district. As a Federal agency, USDA- ARS is required to comply with Section 106 of the National Historic Preservation Act (NHPA), which requires the agency to consider the effects of Federal undertakings on properties included in or eligible for the NRHP.

The USDA-ARS has determined that disposal of surplus properties that contribute to the NRHP-eligible BARC Historic District will have an adverse effect on the NRHP-eligible BARC Historic District, and the Maryland State Historic Preservation Office (SHPO) agreed. USDA-ARS has a Programmatic Agreement (PA) to minimize and mitigate the effects of the proposed demolition program on historic properties, including the buildings themselves and the overall NRHP-eligible historic district. This Statement Of Work (SOW) addresses Phase I of the PA.

2.0 Scope

Following guidelines defined here, provide demolition of buildings site improvement, and utility connection up to point of utility infrastructure tap, and after removal of demolished material, restore of building site to natural contours and vegetation. There are additional requirements identified for removal and disposal of hazardous material, removal and storage (as Value Salvaged Materials) of reclaimed material, and preparation of documentation for compliance with historical preservation requirements.

Building Descriptions

1. Building 009 consists of a long, horizontal headhouse. Originally, the building had six greenhouses attached at right angles to the headhouse. However, since the completion of the 1995 Maryland Inventory of Historic Properties Form and National Register of Historic Places (NRHP) Determination of Eligibility, the six greenhouses attached to the rear of the building have been demolished. Because of its sloped site, and to prevent shading of the greenhouses, the

2024-05-08 Page 4 of 11 building is stepped to follow the contours of the topography. The 1-1/2-story Georgian Revival headhouse is of concrete block construction with brick veneer walls and concrete foundations. All downspouts and gutters are copper; the roof is covered with rubber slate shingles that originally had slate throughout. Decorative detailing is of limestone, with the exception of windowsills and interior door lintels, which are of cast stone. The building, vacant since 2009, is in poor/fair condition. Per attached HAZMAT report, the following is noted for removal and disposal:

Asbestos-Containing Materials (ACM), Lead-Based Paint (LBP), and Other Potentially Regulated Materials (OPRM).

2. Building 018 is located at the North Farm of BARC and was constructed in 1933-1934 by the USDA as a foreman’s cottage for early superintendents and facility staff. The residential building is a one-story, wood-frame bungalow clad with painted horizontal cement board siding. It features a concrete-block foundation, a gable roof with a south-facing cross-gable, and an interior brick chimney. The roof is clad with asphalt shingles and features overhanging soffits. A screened façade porch is supported by brick piers, covers the entry, and spans three of the elevation’s four bays (south to north). The fourth bay contains an exterior storm window sash over plywood, and the remaining fenestration is covered with plywood. The building features full-sized and one half-sized windows that are filled with exterior storm sashes over plywood and double-hung six-over-one wood window sash with exterior storm windows.

The south elevation of the basement story features an overhead panel garage door. The garage is accessed by a ramp with poured concrete walls. This feature was likely added when the building was moved in the 1940s, as it was not mentioned in the 1935 description. Per attached HAZMAT report, the following is noted for removal and disposal: LBP and OPRM.

Reclamation: The pier on the right side of the porch when standing facing the house from the street. See photo-reclaim pier from the top of the porch/door frame (there is a small capital at the top, include this) to the porch floor.
