Report Designation: Final Environmental Impact Statement

Abstract: The U.S. Army Corps of Engineers, Kansas City District, has developed an Environmental Impact

Statement (EIS) for the National Geospatial-Intelligence Agency (NGA). The EIS analyzes the potential

environmental impacts associated with siting, constructing, and operating the Next NGA West Campus in

the metropolitan St. Louis, Missouri, area. NGA needs to construct the Next NGA West Campus because its

current facilities at South 2nd Street in St. Louis are constrained and functionally obsolete. Four alternative

locations for the Next NGA West Campus are under review, including the Fenton Site (St. Louis County,

Missouri), Mehlville Site (St. Louis County, Missouri), St. Louis City Site (City of St. Louis, Missouri), andSt. Clair County Site (St. Clair County, Illinois). Environmental resources and concerns considered in the EIS

include socioeconomics, land use and community cohesion, health and safety, traffic and transportation,

noise, hazardous materials and solid waste, utilities, cultural resources, visual resources, water resources,

biological resources, geological and paleontological resources, air quality and climate change, and airspace.

Executive Summary

ES-1 IntroductionThe National Geospatial-Intelligence Agency (NGA) is investigating sites for the construction and operation

of the Next NGA West Campus in the greater St. Louis metropolitan area. This effort is required to replace

mission critical facilities at the current St. Louis facility (South 2nd Street facility), which have exceeded their

service life and can no longer support the technology changes required for the NGA mission.

The Kansas City District of the U.S. Army Corps of Engineers (USACE) has developed the enclosed

environmental impact statement (EIS) in accordance with the National Environmental Policy Act of 1969

(NEPA) to evaluate the social and environmental impacts associated with the construction and operation of

the Next NGA West Campus. NGA is the proponent of this action and the U.S. Air Force (USAF) is a

cooperating agency under NEPA because the USAF may be the ultimate property owner of the Next NGA

West Campus. The Federal Aviation Administration (FAA) is a coordinating agency on this action because it participated in the purchase of the St. Clair County Site and has associated grant assurance obligations. The

FAA is also acting as the airspace authority for this EIS.

The scope of this EIS includes the potential environmental impacts caused by the proposed construction and

operation of the Next NGA West Campus in the St. Louis metropolitan area. The intent of the EIS is to

inform the NGA decision makers of the potential project impacts through a complete and objective analysis of

the alternatives. Four site alternatives that would meet the purpose and need of the project, as well as a No

Action Alternative, are considered in the analysis.

The Agency Preferred Alternative was identified as the St. Louis City Site based on its ability to deliver a

location that met the schedule, reduced costs, delivered a location that best served the mission and vision for

NGA’s future, and minimized impacts to the environment.

If NGA moves from its existing location, the current property owner, the USAF, in conjunction with the NGA

and General Services Administration, will be responsible for addressing the future use of the vacated South

2nd Street facilities. Insufficient information is available to discuss possible future uses of the South 2nd Street

facilities at this time; therefore, use of these facilities after NGA vacates is not part of this EIS. The General

Services Administration will prepare the necessary NEPA documentation and conduct the National HistoricPreservation Act Section 106 consultation for the future use of the South 2nd Street facilities when potential

alternative uses have been identified.

ES-2 Purpose and Need for Action

ES-2.1 Purpose

The purpose of Next NGA West Campus is to enhance current and future missions, improve resiliency, and

resolve security challenges associated with the South 2nd Street facilities. Challenges associated with the

EXECUTIVE SUMMARY

ES093014083520ATL ES-3

• Data center (may be constructed sometime in the future)

• Central utility plant

• Visitor control center

• Remote inspection facility

• Primary and secondary access control points

•

Security fence or wall around the site perimeter

• Supporting infrastructure, such as parking, interior roads, and sidewalks

ES-4 Description of the No Action AlternativeUnder the No Action Alternative, the NGA would not construct or operate a new campus. NGA would remain

at the South 2nd Street location and these facilities would not be renovated or upgraded. Further, it is assumed

the current conditions at each of the proposed sites would continue. The No Action Alternative does not meet

the purpose and need of the Proposed Action. The No Action Alternative analysis serves as the baseline for

the comparison of environmental impacts.

ES-5 Alternatives Carried Forward for AnalysisSiting, construction, and operation of the Next NGA West Campus at one of four alternative locations

(Figure ES-1) are considered in the EIS. The alternative locations are described in detail in the following

subsections.

ES-5.1 Fenton Site

The Fenton Site (1050 Dodge Drive, Fenton, Missouri) is located in south St. Louis County, Missouri, on a

167-acre tract adjacent to Interstate 44/U.S. Route 50. This site is located within a larger 294-acre parcel

proposed for redevelopment as mixed-use build to suit industrial/commercial use along the Meramec River.

This property is the former location of a Chrysler automobile assembly plant that was demolished in 2009.

The existing site is flat and covered almost entirely in concrete and asphalt, which would be removed under

the Proposed Action. The property is unoccupied with the exception of a trailer used by the site developers as

a sales office. The Fenton Site is owned by a private developer and is currently for sale.

ES-5.2 Mehlville Site

The Mehlville Site (13045 Tesson Ferry Road, St. Louis, Missouri) encompasses a 101-acre tract in south

St. Louis County, Missouri. The site is slightly graded with an existing 645,520-square-foot two-story officecomplex with interconnected buildings constructed for Metropolitan Life Insurance Company beginning in

1976. The Mehlville property has a well-maintained office setting and grounds with parking, infrastructure,

and interior stormwater retention pond. Along the southern border of the Mehlville Site, the property contains

natural forested conditions. Because of NGA’s unique requirements, the existing office complex cannot be

renovated. The building, structures, and infrastructure would be removed as part of the Proposed Action. The

Mehlville Site is owned by private interests.

sites for the public and agencies. A detailed summary of the scoping and DEIS public comment meetings are

presented in Appendices 1B, 1C, and 1D.

ES-7 Environmental JusticeEach alternative site location was assessed in consideration of Executive Order (E.O.) 12898 Federal Actions

to Address Environmental Justice in Minority Populations and Low-Income Populations. Section 5.0, Environmental Justice, presents a description of the community around each site, along with the comparative

proportion of minority and low-income populations. U.S. Environmental Protection Agency’s (USEPA)

environmental justice screening and mapping tool (EJSCREEN) and Census data were used to determine

whether there are environmental justice concerns present at each site.

The St. Louis City Site is the only site with substantial minority and low-income populations that may be

affected by the Next NGA West Campus, based on the EJSCREEN tool results and Census data. If the

St. Louis City Site is selected, the short-term impacts of relocation for residents and business would be borne

primarily by minority and low-income populations. However, this impact is not high and adverse in light of

the Missouri relocation statutes (Sections 523.200–215, RSMo, 2014), which also meet the requirements of

the federal Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970, as amended.

Additionally, the Next NGA West Campus is consistent with the City of St. Louis’ redevelopment plans for

the area and may provide a stabilizing effect, indirectly leading development attraction and eventual

momentum toward enhancing the NorthSide community resources.

E.O. 12898 calls for federal agencies to provide opportunities for stakeholders to obtain information and

provide comment on federal actions. NGA is complying with E.O. 12898 by conducting a public involvement

program that includes targeted efforts to engage, inform, and solicit input from minority and low-income

populations as demonstrated through additional meetings in the St. Louis City Site neighborhood and added

outreach to community leaders. Additional public outreach is being conducted as part of the cultural resources

mitigation as described in Section ES-11.3, St. Louis City Site, and Section 4.8, Cultural Resources.

ES-8 Selection of Preferred Alternative NGA chose the preferred site after gathering information from agencies, the public, and others through the

NEPA process and by performing the environmental impact analysis shown in this EIS. NGA considered the

information gathered during the EIS, along with other critical factors such as its ability to perform its mission,

maintain a secure environment, retain and recruit employees, and meet the construction schedule. The final

selection process and decision is described in detail in Sections 2.7 and 2.8 of this FEIS and documented in

the Record of Decision, which will be distributed after publication of the Final EIS (FEIS).

NGA has selected the St. Louis City Site as its Preferred Alternative.

ES-9 Approach to Environmental AnalysisThe direct, indirect, and cumulative impacts of implementing NGA’s Proposed Action are evaluated in

accordance with the CEQ’s guidance for implementing NEPA (CEQ, 1983, 1997). The construction of the

proposed project would occur over a 5-year period and would include direct and indirect effects on the human

and natural environments. Direct effects are caused by the action and occur at the same time and place,

whereas indirect effects are caused by the action, reasonably foreseeable, and occur later in time. Cumulative

impacts result from the incremental impact of the action when added to other past, present, and reasonably

foreseeable actions, which may be undertaken by other private or public entities. Fourteen natural and human

resource areas are analyzed in the EIS.

ES-10 Comparison of Environmental Impacts by AlternativeTable ES-1 presents the direct/indirect impacts, cumulative impacts, and the environmental protection

measures by resource area to illustrate the impact differences between the alternatives. Table ES-1

summarizes the areas where potential environmental impacts are present; impacts that were deemed

no/negligible in the analysis are not described in detail.

There have been a number of revisions to the impact findings shown in this table since the publication of the

DEIS. These revisions were based on analysis performed in response to input received from public and

agency comments. For an explanation of changes made, please see the comment response summary provided

in Appendix 1D.
