The U.S. Army Corps of Engineers (USACE), Baltimore District, in coordination with the USACE Mission Support Battalion (UMSB), is preparing an Environmental Assessment (EA) to evaluate the potential environmental impacts associated with undertaking the following projects outlined within the Area Development Plan (ADP) for the Humphreys Engineer Center (HEC), which is managed by the USACE Mission Support Battalion:

• Renovate Kingman, Casey, & Cude Buildings
• Construct Conference & Activities Center
• Secondary Egress
• HEC Warehouse – HPTC
• Perimeter Fence
• Sidewalk Improvements
• Implement Pedestrian Spaces
• Demolition of Bunkers
• Auditorium
• Battalion Operations Facility

The EA will also assess the potential impacts of the No Action Alternative, in which USACE does not implement the projects outlined within the ADP.

What is an Area Development Plan? 

An Area Development Plan (ADP) is a strategic framework used in urban and regional planning to guide the growth, organization, and use of land in a specific area. Its purpose is to create a comprehensive, long-term plan that integrates land use, infrastructure, environmental sustainability, and community needs to support economic, social, and environmental goals. This ADP aims to balance the demands of future HEC (Humphreys Engineer Center) development with current resource management, ensuring that space is used efficiently while enhancing the quality of life for tenants and promoting sustainable growth.

The purpose of the Area Development Execution Plan (ADEP), which will be provided in the Prefinal Submittal after further validation of the Preferred Alternative, is to outline a phased and actionable strategy for implementing the proposed projects within this ADP. As a strategic framework, the ADP guides the growth, organization, and land use at HEC, integrating land use, infrastructure, environmental sustainability, and community needs. By addressing current resource management and anticipating future development, the ADEP ensures efficient space utilization, enhances quality of life for tenants, and supports sustainable growth. This approach balances the installation’s missiondriven priorities with long-term resilience and adaptability.

USACE Baltimore District, in coordination with the USACE Mission Support Battalion (UMSB), will hold a public meeting to discuss the proposed implementation of activities outlined in the ADP for the Humphreys Engineer Center (HEC).

HEC is located in Alexandria, Virginia, situated along the western bank of the Potomac River, approximately 10 miles south of Washington, D.C. This area is part of the broader Washington Metropolitan Region, a significant urban and suburban zone characterized by its proximity to the nation’s capital and various federal installations. HEC is close to major transportation corridors, including Interstate 95 (I-95) and the Capital Beltway (I-495), which connect HEC to many urban centers in the region.

HEC’s existing campus consists of a series of research and development facilities constructed in the 1980s. HEC includes modern office buildings, research laboratories, and conference facilities equipped with the latest technology to support its mission. Existing buildings at HEC include:

• Cude Building: Completed in 1988, the Cude building serves as the central administrative hub for HECSA (Humphreys Engineer Center Support Activity). It houses offices for various USACE (United States Army Corps of Engineers) divisions and departments, including project management, planning, and administration support.

• Kingman Building: Kingman serves as an administrative center for HEC and provides offices for USACE’s civic works mission. The building also supports training programs and workshops aimed at advancing USACE’s capabilities in water resource engineering.

• Casey Building: Completed in 1981, the Casey Building has historically been used as a classroom training facility. Today, the building houses the USACE Finance Center and the Institute for Water Resources, a non-USACE tenant conducting research and development at HEC.
