Recent and Upcoming Meetings

9

• Maintain a unified identity for the entire alignment while also encouraging unique individual characteristics of each station

• Explore partnering with private developers to develop air rights above all proposed stations while also ensuring station design can accommodate future development

• Try to reduce escalator runs and distance to Commerce Station platform

• Design Pegasus Plaza headhouse to be minimalist in style and design the headhouse and park as one space to minimize impact on the park

• Explore developing the East Transfer Center as a future development site

• Design of the space at Swiss/Good Latimer wye junction with landscaping and public art to prevent it from becoming a purely utilitarian space

Urban Design Peer Review PanelKey Comments

10

• Key topics at April 16, 2020 meeting included:

1. Review D2 Subway current design

2. Discussion of two City of Dallas ideas for alignment and roadway modifications if the D2 Subway portal was to move into downtown to allow for at-grade crossing under I-345

3. Review early concepts for I-345 below-grade options to understand how they would interface with D2 Subway and city streets

4. Discuss next steps to advance both projects in coordinated manner

City of Dallas Concept #1D2 Subway At-Grade under I-345

DART •

DART Review of City of Dallas Concept #1 Pacific Portal (Plan)

13

DART

• Actual length of portal would raise Elm Street about 5 feet

• Profile under Commerce Street is raised by about 14 feet

– Cut-and-cover through Main Street Garden, along Commerce for station and likely for entire alignment given short length of mined sections (including cut-and-cover through Belo Garden)

• Requires displacement of two Elm Street Parking Garages with long standing opposition of property owners and businesses who use garages

• Undesirable at-grade crossing of major arterial at portal exit location due to reconstruction of Cesar Chavez Boulevard & Pearl Street

• Bisects DART East Transfer Center potential development site

DART Review of Concept #1

City of Dallas Concept #2 Elm Portal

DART Review of Concept #2

16

• New vertical profile developed from portal placed east of Cesar Chavez along Elm

• Actual length of portal extends under I-345

• Portal would impact I-345 columns and northbound I-345 ramp to Elm

• Station within Elm Street would close Elm and create tight station platforms along sidewalk (Epic access eliminated)

• Double track LRT within Elm would possibly allow for one lane on Elm

• Undesirable 10 mph curve at Elm/Good Latimer to be able to place junction within Marquis apartments

• Station under Elm Garages would require displacement and relocation of garage to nearby site like Concept #1

DART Review of Concept #2

17

• TxDOT is still in feasibility study phase but developed several concepts that appear to work with current design of D2 Subway

• There would be a requirement for a pump station, ongoing operating costs of pump station, and infrastructure for taller walls due to deeper facility

– Opportunity for cost-sharing of agencies as contingency program for future facility

TxDOT I-345 Options

18

Path Foward

19

• Agencies will continue to meet bi-weekly especially related to I-345 options and city street interface

• DART will continue to advance project as currently contained in 20% and in SDEIS

• Potential schedule changes to both D2 Subway and TxDOT Feasibility Study may allow more time for collaboration and resolution of details

• City of Dallas may want to present the D2 Subway alternatives at future meetings as part of process and documentation

CIG Program Status

Capital Investment Grant (CIG) Status Update

21

• Staff are continuing to coordinate with FTA towards a Core Capacity submittal in August/September timeframe

– Submittal will include 6-month advance notice to request entry into Engineering phase

• It is unknown if FTA will be changing process due to the COVID-19

• DART staff is coordinating internally on required readiness documents that need to be complete before FTA would authorize DART into Engineering

• Project schedule changes will factor into the decision to advance project past this Project Development phase into Engineering
