DART Lake Highlands LRT Station
CATEGORICAL EXCLUSION
(1995) and Local Environmental Assessment (LEA), (1997). This station was
included in the Final LEA but deferred until Blue Line ridership warranted
expansion. A major funding source for this proposed station is $10.75 million in
Congestion Mitigation and Air Quality (CMAQ) funds plus the local match.
This CE is limited to the evaluation of the impacts and benefits of the proposed
station, Phase I and Phase II parking areas, and eastside access pedestrian
walkway located within DART-owned Right-of-Way (ROW), the Walnut Hill Lane
ROW, and a portion of the Prescott Realty property. Plans-foro -Other elements
outside of the DART ROW include a bus circulation facility to be served by Route
583 and Kiss-and-Ride spaces that would be provided by the Lake Highlands
Town Center development. These elements are being designed and funded by
the developer with coordination and review by DART.
Site Description
The proposed station's limits would extend approximately 750 feet north and 250
feet south of Walnut Hill Lane. Walnut Hill Lane is grade separated approximately
21 feet above the existing DART Blue LRT line. Because of track modifications
required to accommodate the vertical curve described in the "Trackway
Modifications" section, the proposed 365-foot platform would be 20 feet shorter
than the current DART criterion of a 385-foot platform that would accommodate
three standard LRT vehicles or may accommodate three Super Light Rail
Vehicles (SLRV). A design exception to DART Design Criteria would be required
for this element. The surrounding grade outside of the ROW and proposed
platform is steep. The grade slopes up 16 feet to White Rock Trail on the east
and down 39 feet to White Rock Creek on the west.
In addition to the above improvements, DART would construct a parking lot to the
north and west of the station platform. This parking area would be constructed in
two phases. Phase I would included .45 acres of parking with approximately 62
general use parking spaces and five handicap parking spaces. Phase II would
include approximately an additional .45 acres of parking area and approximately
62 general use parking spaces. Phase II would be constructed on property
owned by Prescott Realty Group (or its successor) at a later date. Phase II will
only be implemented if parking demand warrants the additional spaces.
South of the proposed station platform, a walkway would be constructed to allow
pedestrians to access the station from Walnut Hill Lane and White Rock Trail
Road. Pedestrian crossing facilities and ADA ramps would be constructed at the
intersection of White Rock Trail and Walnut Hill Lane. The pedestrian walkway
would begin at this intersection and continue west within the City of Dallas ROW
for approximately 360 feet. The walkway would then turn north beneath the
Walnut Hill bridge, within DART-owned ROW, for approximately 160 feet to the
southern edge of the station platform.Page 2
