LANGLEY, FAIRFAX COUNTY, VIRGINIA -
MODIFICATION TO THE MASTER PLAN,
OFF-SITE ROAD IMPROVEMENTS TO ROUTES 123 AND 193
AND MAIN ENTRANCE IMPROVEMENTS
Report to the General Services Administration and
the Central Intelligence Agency
Decemb+~t ~+, -1486
The Commission approves
1. the modification to the Master Plan. for the Central Intelligence
Agency, Langley, Fairfax County, Virgiirita, ,providing for off-site road
improvements to Routes 123 and 193, as shown on NCPC Map File No. 2201.10(05.12)-
29843;
2. the preliminary :and final off-site road improvement plans for
Routes 123 and 193 along the sate of the Central Intelligence Agency, Langley,
Fairfax County, Virginia, as shown on NCPC Map File No. 2201.1Ot44.00)-29844; and
3. the revised final site development plan for the main entrance
improvements at the Central Intelligence ;Agency, Langley, Fairfax County,
Virginia, as shown on NCPC Map File No. Z2?1I0(44.00.)-29844.
Description of Proposal
The proposal provides for off-site road improvements to Routes 123 and 193 and
the main entrance to the Central Intelligence Agency (CIA)'Headquarters. The
proposal also includes a modification to the master plan to reflect the proposed
off-site road improvements. Based on previous Commission action and the
forecasted construction and occupation of the new CIA Headquarters Building, the
approved expansion will result in an increase in the number of persons entering
and leaving the site by motor vehicle. The CIA and the General Services
Administration have submitted this proposal in an effort to mitigate the impact

on existing traffic patterns and circulation, and the surrounding residential
community.
The off-site road improvements are an at-grade solution wherein traffic flow
would be controlled by interconnected signalization and intersection
channelization. The eastbound lanes of Route 123 would be relocated northerly,
adjacent to existing westbound Route 123. Route 193 would be realigned to
intersect with Route 123 opposite Potomac School Road. Two lanes in each
direction would be provided on Route 123. A variable width median would be
provided to separate the eastbound and westbound lanes of Route 123, and the
present median width would be retained at each end of the project. A third
westbound lane to be provided along Route 123 through the intersection with the
CIA entrance would drop as a free flow right turn lane to Route 193.
Dual turning lanes would be provided for left turns into and right turns out of
the CIA entrance. The entrance would be widened to a four-lane divided cross
section. A single turn lane would be for left turns out of the CIA, and dual
left turn lanes would be required for the Route 193 turn onto eastbound
Route 123. The left turn lane for turns into the Federal Highway
Administration/CIA (Turkey Run Farm) access road would be retained, and this
access roadway would widen at the intersection of Route 193 to provide two
outbound lanes--an exclusive lane for both left and right turning movements.
Traffic signals would be installed at the Route 123/CIA entrance, the
Route 193/Potomac School Road and Route 123 intersection, and the Savile Lane and
Route 123 intersection.
The proposal also provides for the usual signing and pavement markings. General
landscaping would be provided along the highway in various locations augmenting
the seven-foot precast barrier wall which would buffer the adjacent properties
including all homes in the Evermay development. The area along the south side of
Route 123, at the CIA entrance intersection, would be extensively landscaped with
existing and new planting.
Previous Commission Action
At its June 28, 1984 meeting, the Commission:
1. approved the final site and building plans for the Headquarters
Consolidation, Phase I, Bid Package No. 2, at the Central Intelligence Agency,
Langley, Fairfax County, Virginia, as shown on NCPC Map File No. 2201.10(38.00)-
29494, except the portion of the south access road extending northward from State
Route 123 fora distance of 400 feet, pending review and approval by the
Commission of the selected plan for off-site road improvements, including
required adjustments to the south entrance road, if any;
2. took no action on the proposals for off-site road improvements, which
were still in the form of alternatives; and
3. requested that the Central Intelligence Agency submit the preferred
plan for off-site road improvements for Commission review immediately upon its
selection and the revision, as required, of plans for the southernmost portion of
the south entrance road, with appropriate back-up calculations.

Response to Commission Action
In response to previous Commission action, the CIA continued its efforts, in
conjunction with the Virginia Department of Highways and Transportation (VDH&T)
and a Traffic Advisory Committee (TAC), to identify and select a preferred plan
for the off-site road improvements to Routes 123 and 193. At its October 17,
1986 meeting, the TAC reviewed and raised no objections to the final project
plans. Both the VDH&T and Fairfax County concurred with the selection, as
members of the TAC. Some of the major resolutions include a traffic signal at
Savile Lane, additional landscaping in buffer areas, provision of a precast
barrier architecturally finished on both sides, and extension of the barrier to
include all homes in the Evermay development. Back-up calculations associated
with the road improvements have been provided with the present submission.
Conformance with the Comprehensive Plan
The proposals are consistent with the Comprehensive Plan for the National
Capital. The Federal Facilities element designates the site of the CIA for
Executive Branch Administrative Facilities Principal Offices.
Conformance with the Master Plan
The proposed projects are consistent with the proposed Modification to the Master
Plan for the Central Intelligence Agency, which is included for Commission action
as part of this submission.
Conformance with the Federal Capital Improvements Program
The proposed projects are not included in the 1987-1991 Federal Capital
Improvements Program. The Central Intelligence Agency Headquarters Consolidation
project first appeared in the 1983-1987 Federal Capital Improvements Program.
The CIA Headquarters Consolidation project also appeared in the 1984-1988 FCIP
and included the following statement: "Funds for off-site road improvements at
Route 123-Route 193 intersection are included in the overall scope of the
project."
Environmental Impact
Pursuant to P.L. 91-190, the CIA has determined that an environmental impact
statement is not required for the proposal. Instead, an environmental assessment
prepared by the Virginia Department of Highways and Transportation has been
submitted. In addition, the CIA has submitted two technical memorandums which
describe the traffic effects of the proposal.
The traffic analysis, prepared by VDH&T, examines the effect of the CIA expansion
on nearby roadways serving the CIA. The analysis involves determining the
existing and projected traffic volumes on roadways within the study area, with
and without CIA expansion. In addition, certain assumptions regarding the
operating condition of the George Washington Memorial Parkway (GWMP), a major
traffic carrier in the study area, are given to identify potential spillover
effect on Route 123. A level-of-service (LOS) analysis is used to identify
operating conditions and specific problem areas in 1986 and 2005. The overall
traffic growth identified during the process of developing level-of-service

conditions is used to assess the effects of a number of alternative
transportation improvements on traffic conditions.
The proposed road improvements along Route 123 consolidate intersections and
essentially eliminate weaving areas both eastbound and westbound. The entrance
to the CIA in the morning peak hour is projected to operate at acceptable levels
(C or D) in 2005. During the evening peak hour, level-of-service is expected to
be marginally acceptable or level of service "D". The GWMP and its interchange
with I-495 will continue to experience major traffic congestion during the P.M.
peak hour even with the proposed improvements on Route 123. The recently
completed acceleration lane at the CIA/GWMP interchange and the reconstruction of
the Cabin John Bridge will ease traffic flow somewhat. However, the significant
amount of traffic which is projected to use the I-495/GWMP interchange during the
evening rush hour and the physical constraints associated with widening the
Beltway in the vicinity of the GWMP make it unlikely an improvement on the GWMP
will be seen in 2005.
Regional Referral
Prior to approving the existing master plan on January 21, 1982, the Commission
circulated it for regional review and comment to affected local, State and
regional agencies. At that time, questions were raised about the adequacy of
proposed access improvements to the site. A restudy was, therefore, initiated by
the CIA in conjunction with the VDH&T and TAC, which included representatives of
several McLean citizen groups (Nancy Falk and Shiva K. Pant of Fairfax County,
Congressman Frank R. Wolf, State Senator Clive Duval, Fairfax Delegate Robert
Andrews, and representatives of the National Park Service and this Commission).
The TAC met in a number of both formal and informal sessions to review the off-
site road improvement proposals to be funded by the CIA and community concerns.
At the October 17, 1986 meeting of the TAC, the final project plans were reviewed
and no objections were raised. Some of the major concerns resolved in favor of
the community were the inclusion of a traffic signal at Savile Lane, additional
landscaping in buffer areas, provision of a precast barrier architecturally
finished on both sides, and extension of the barrier to include all homes in the
Evermay development. Both VDH&T and Fairfax County approved the plans as part of
the TAC review and indicated the Commission need not circulate the proposed plans
to them for another review.
The proposed plans were transmitted to the Metropolitan Washington Council of
Governments and the Northern Virginia Planning District Committee on November 13,
1986, for review and comment with a request fora waiver of the usual 60-day
review period because VDH&T is to advertise for bids in mid-November and award a
construction contract in January. No comments have been received from either
reviewing agency as of this time.
Historic Preservation
The General Services Administration and the Central Intelligence Agency have
determined that the proposals are not subject to Section 106 of the National
Historic Preservation Act of 1966, as amended.

Evaluation
No major issues are raised by the final site development plans for the off-site
road improvements contained in the submission. During the course of the
preparation of the project plans, the CIA has effectively responded to all of
the concerns and recommendations of the Commission regarding the project plans.
As noted, the final plan for the off-site road improvements is consistent with
the proposed modification to the master plan which includes improvements to the
CIA main entrance.
The CIA has worked extensively with the Virginia Department of Highways and
Transportation, the Traffic Advisory Committee, which included representatives of
several citizen groups, and the Commission staff to identify a plan that
satisfies all concerns to the extent possible. The proposed improvements have
been approved by Fairfax County.
