Resource Layer Data1

Natural Resources - Water Resources 

Wetland: This data layer shows those areas on the Fort Belvoir Main Post that are inundated or saturated 

by surface or ground water at a frequency and duration sufficient to support, and that under normal 

conditions do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. 

This data was prepared for planning level purposes only and does not represent jurisdictionally delineated 

wetland boundaries. 

For EPG and the hospital site on the Main Post, wetlands were jurisdictionally delineated in January 2007 

(USACE, 2007). More information on wetlands can be found in Section 4.8.1.2 of the Fort Belvoir EIS. 

RPA: Resource Protection Areas (RPAs) are designated under the Chesapeake Bay Preservation 

Ordinance. RPAs are regulatory zones along streams protected from most forms of development to 

preserve their function as biological filters and buffers. RPAs generally include major floodplains, 

riparian areas, and vegetated lands within 100 feet of tidal and nontidal wetlands, tidal shores, and 

perennial streams. RPAs outside the installation were provided by Fairfax County GIS (2006). For EPG 

and the hospital site on the Main Post, RPAs were field delineated and reviewed for perenniality in 

January 2007 (USACE, 2007). More information on RPAs can be found in Section 4.7.1.5.1. 

100-year Floodplain: Areas designated by the Federal Emergency Management Agency (FEMA) as 

having potential for flooding at least once during a 100-year span. More information on floodplains can 

be found in Section 4.7.1.5.2.This data was obtained from FEMA (1990). 

Riparian Buffer: Riparian areas are generally areas of land adjacent to a body of water, stream, river, 

marsh, or shoreline that are a transition zone between the aquatic and terrestrial environment. Riparian 

buffers were delineated by Fort Belvoir Directorate of Public Works (DPW)-Environmental and Natural 

Resources Division (ENRD) using the following criteria: 35-foot buffer around intermittent and perennial 

streams, soils with slopes greater than 15 percent, and alluvial soils. More information on riparian buffers 

can be found in Section 4.8.2.4.2 of the Fort Belvoir EIS. 

Natural Resources – Sensitive Habitat 

Special Species Area: Buffers for flora identified by the USFWS and VDGIF as special species (on 

federal and state threatened and endangered species lists) and potential habitat for threatened and 

endangered fauna species known to occur on Fort Belvoir. More information on special species areas can 

be found in Section 4.8.2.3.2 of the Fort Belvoir EIS. 

Migration Corridor: The forest and wildlife migration corridor is a tract of contiguous forested land in 

which aggregate of fauna species are known to migrate from one habitat to another. The corridor was a 

mitigation measure in the BRAC 88 EIS and ROD and again to offset impacts from the siting of the 

Defense Logistics Agency (DLA) complex. More information on the migration corridor can be found in 

Section 4.8.2.1.2 of the Fort Belvoir EIS.

 Source: All data unless otherwise noted is from Fort Belvoir GIS, 2006. There are no maps of the GSA Parcel in 

this appendix because the site does not contain any of the resources shown on the maps in this appendix or resource 

information was not available.

Fort Belvoir, Virginia June 2007 

 J-7

Wildlife Management Area: There are two wildlife refuges (Accotink Bay and Jackson Miles Abbott 

Wetland Refuge) and seven other areas designated as Wildlife Management Areas (WMAs) on Fort 

Belvoir’s Main Post. These areas are habitat for several rare animals, plants, plant communities, and 

habitats, including bald eagle, peregrine falcon, and wood turtle and includes all of the resource protection 

areas along Dogue Creek main stem in the North Post. More information on wildlife management areas 

can be found in Section 4.8.2.2.2 of the Fort Belvoir EIS. 

Environmental Quality Corridor (EQC): The (EQC) on EPG is an open space system designed to link 

and preserve natural resource areas and provide passive recreation. The EQC has been set aside in an 

agreement between Fort Belvoir and Fairfax County to protect and restore environmentally-sensitive 

lands, including 100-year floodplains, steep slopes (gradients of 15% or greater), and riparian areas. The 

EQC is broader in area and extends further upstream than areas afforded protection under the County’s 

floodplain and RPA regulations. EQCs are not enforced by regulation, therefore this policy is not 

implemented for “by right” development. Although the policy is not enforceable on federal property, Fort 

Belvior respects the policy and abides by it to the maximum extent practicable (Fort Belvoir DPW 

ENRD, 2005c). However, according to the Fairfax County Comprehensive Plan, development on EPG 

should occur outside of the EQC. For EPG and the hospital site on the Main Post, EQCs were field 

delineated in January 2007 (USACE, 2007). No EQCs are available elsewhere on the Main Post. More 

information on the EQC can be found in Section 4.8.2.4.2 of the Fort Belvoir EIS. 

Grassland Management Area: Grassland management areas are unimproved open fields or areas that 

are infrequently mowed. More information on grassland management areas can be found in Section 

4.8.1.1 of the Fort Belvoir EIS. 

Other Conservation Area: Other conservation areas identified in the INRMP include wetland 

conservation areas, buffers for flora identified by the USFWS and VDGIF as special species (on federal 

and state threatened and endangered species lists) and potential habitat for threatened and endangered 

fauna species known to occur on Fort Belvoir. These total about 3,990 acres. More information on 

conservation areas can be found in Section 4.8.1.5 of the Fort Belvoir EIS. 

PIF Priority Area: Areas designated as buffers to bird nesting grounds for 61 different priority bird 

species. Species and habitat are designated by DoD and VDGIF. More information can be found in 

Section 4.8.1.4.2. 

Cultural Resources 

Historic Building: Buildings or structures protected under the National Historic Preservation Act as 

having historical significance or value. More information can be found in Section 4.9.1.2.5. 

Cemetery: Areas currently or previously used as cemeteries. More information can be found in Section 

4.9.1.3.2. 

Historic District: Districts protected under the National Historic Preservation Act as having historical 

significance or value. More information can be found in Section 4.9.1.4. 
Final Environmental Impact Statement 

Fort Belvoir, Virginia June 2007

Historic Overlay District2: Areas designated by Fairfax County surrounding adjacent off-post historic 

properties: Woodlawn Plantation/Friends Meeting House, Pohick Church, and Mount Air. The overlay 

districts are 1⁄4 mile buffers surrounding the properties. More information can be found in Section 4.9.1.4. 

Archaeological Site: Sites recognized by National Register of Historic Places as being eligible or 

potentially eligible for listing on the National Register of Historic Places (NRHP). Note: due to concerns 

with disturbing sites, archaeological sites are not shown on the figures. More information on 

archaeological sites can be found in Section 4.9.1.3. 

Operational Constraints 

Fuel Tank: This data layer, also known as petroleum storage areas (PSAs), depicts the geographic 

locations of aboveground or underground storage tanks (ASTs and USTs) for holding fuels on a 

temporary basis prior to transfer or use. More information can be found in Section 4.13.2.2. 

Pollution Release Site (PRS): Of the more than 1,000 Petroleum Storage Areas at Fort Belvoir, about 

150 have released petroleum into the environment, resulting in designation of PRSs. Fort Belvoir is 

actively addressing these releases. Site investigations are performed to delineate the impacted areas of 

soil and groundwater. More than 10 sites have been actively remediated to the remedial endpoints with 

many of the sites of releases gaining acceptance of no further action by VDEQ. Fort Belvoir is actively 

managing their PRSs under the VDEQ Petroleum Program. More information can be found in Section 

4.13.1.1

SWMU: Solid Waste Management Units are any unit which has been used for the treatment, storage, or 

disposal of solid waste at any time. These units include storage tanks, dumpsters, waste piles, drain 

fields, waste treatment units, surface impoundments, and any other unit that satisfies the above definition. 

More information can be found in Section 4.13.1.3. 

Former Range: Areas that were once used for military training or testing. These include those that have 

already undergone cleaning and clearing as well as those that still may possess hazards related to their 

former use. More information can be found in Section 4.13.2.1. 

Air Restriction Zone: These areas have some level of restrictions on air space. This can range from 

limits on building heights to controlling access of unauthorized aircraft. More information can be found 

in Section 4.2.1.2.3.
