Briefing on the Cotton Belt Corridor
Committee-of-the-Whole

• Information reviewed today is currently the basis of the draft 10% design and associated impact analyses, and will be included the Draft EIS which is under development; and included in the financial plan
• Changes to project elements may require a reassessment of impacts and mitigation for inclusion in the Draft EIS
• Board consensus and direction is needed on:
– Alignment deviations?
– Proposed stations? (add, eliminate, defer, relocate)
• Pending city coordination and public comments on:
– Proposed traffic mitigation, including grade separations
– Inclusion of current Equipment Maintenance Facility (EMF) site in Draft EIS with caveat that additional sites are being identified and evaluated

Alignment DeviationCypress Waters Alignment
• Provides station opportunity within DART Service Area within 10-mile segment
• Two miles of new alignment• Freight remains on mainline• Supported by cities of Dallas and Coppell

• Provides grade separation from BNSF freight corridor to ensure no schedule impacts
• Provides area for potential future Frisco line platform

• DFW Airport is constructing DFW Airport Terminal B Station
• TEXRail is constructing:
– DFW North Station Platform for Cotton Belt/TEX Rail transfers
– DFW North Station park-and-ride for shared parking with Cotton Belt
– Single-track connection to DFW Airport Station at Terminal B
Coordination with FWTA TEXRail Project

Operating Plan
• Initial operating plan:
– 5:30 am to 12:15 am
– 30/60-minute service
• Long term operations:
– 20-minute peak service
• Opportunity for through service to Fort Worth on some trains with shuttle connection to terminal

Freight Operations
• Freight operations within Cotton Belt Corridor limit ability for single-track
• 10% design in development assumes full double-track

Stations
17
Proposed Station Locations
• 1983 DART Service Plan identified “fixed guideway” along all corridors; it did not differentiate for light rail, commuter rail or regional rail
• 1989 Transit System Plan discussed technology, noting access only to large business districts for commuter rail
– Generally, stations are typically 3 to 5 miles apart, with exceptions to serve major destinations/employment centers
18
DART Service Plan
• DART Service Plan included criteria adopted to use in locating stations:
– Good accessibility by pedestrians, buses, autos, bikes
– Minimize land acquisition and displacement of people/businesses
– Not located in environmental sensitive areas
– Minimize negative impacts on adjacent neighborhoods
– Comply with community plans/policies and encourage concentration of appropriate development next to station
– Physically integrate stations into existing fabric of communities, especially major activity centers
– Balance the need for access points to population and activities with the station spacing to permit high speed operations

• Existing station/transit center locations to support bus-rail, rail-rail transfers
• April 2010 NCTCOG Cotton Belt Conceptual Engineering and Funding Study
• July 2010 DART Scoping meetings in preparation for the Environmental Impact Statement (EIS)
• Served as basis for project budget

Traffic Analysis and Grade Separations
47
Traffic Analysis Guidance
• Institute of Transportation Engineers (ITE) Light Rail Transit Grade Separation Guidelines (January 2003)
• Transportation Research Board Highway Capacity Manual (HCM, 2000)
• SYNCHRO Software Version 9.0• DART Grade Separation Policy
48
Traffic Impact Methodology
1. Identify all at-grade crossings2. Document existing Average Daily Traffic (ADT) volumes
and estimate future year 2040 ADT using growth factorsa) Growth rates based on ADT trends and socio-economic data for higher
ADT roadways. For lower ADT roadways, a 2% growth rate was used
3. Conduct ADT grade separation warrant screening using ITE threshold guidelines
4. Advance crossings meeting ITE thresholds or that have intersections close to rail crossing for more detailed analysis in accordance with HCM and SYNCHRO software to assess Level of Service (LOS) and/or queue impacts

DART Grade Separation Policy IV.10 Warrants
• Subject to a determination that other reasonable and effective traffic mitigation measures are not feasible, two specific warrants can effectively measure if a street intersecting a rail line should be grade separated. These grade separation warrants are:
– Queuing impacts: “If the presence of DART’s rail line causes vehicular traffic on streets adjacent to the rail line to queue through adjoining intersections or queue through the LRT intersection a queuing impact may exist.”
– Level of Service (LOS) impacts: “If the presence of DART’s rail line causes the level of service (LOS) on streets adjacent to the rail line to drop two or more levels or cause the street to have a LOS of “F”, a LOS impact may exist.”
60
Queuing Definition
• Queuing impacts are identified where:
– Stopped traffic backs up into an adjacent signalized intersection
– Traffic from adjacent intersection backs up onto tracks
61
Level of Service (LOS) Definition
• LOS describes performance of a facility from motorist’s perspective with “A” being best free-flow conditions to “F” representing the worst, congested condition
Level of ServiceUnsignalized Signalized
Average Control Delay (seconds/vehicle)
A ≤ 10.0 ≤ 10.0
B >10.0 and ≤ 15.0 >10.0 and ≤ 20.0
C >15.0 and ≤ 25.0 >20.0 and ≤ 35.0
D >25.0 and ≤ 35.0 >35.0 and ≤ 55.0
E >35.0 and ≤ 50.0 >55.0 and ≤ 80.0

DART Grade Separation Policy IV.10Unwarranted Grade Separation
• For grade crossings that do not meet warrants or where other reasonable and effective traffic mitigation measures are feasible but the city still desires a grade separation:
– DART will design and construct
– DART will contribute a maximum of $1.5 million (1998$) toward construction adjusted for inflation at the time of construction (2017$ - $2.8 million @ 3.5% per year)
– City must agree to pay remainder of incremental cost prior to beginning design
67
Equipment Maintenance Facility
(EMF)
68
• Prior 5% design effort documented and evaluated 11 potential sites
• Key criteria:
– Distance to the Cotton Belt corridor
– Site geometry, size, and topography
– Compatibility with surrounding land uses
– Accessibility of the site
– Potential environmental impacts
– Anticipated cost, ease of implementation
Equipment Maintenance Facility

Equipment Maintenance FacilitySite Inventory (2012)

• Current 10% design effort identifies Luna Road site in Carrollton as it best meets criteria and future needs
• City of Carrollton not supportive; other sites being identified

71
• Existing rail yard in downtown Carrollton to be relocated approximately two miles to the east

Proposed Schedule and Next Steps
73
• Public Meetings November 29, 30 and December 7
– Draft noise/vibration, visual, traffic analysis and mitigation
– Review of stations and alignment
• December 12
– Planning Committee review of public meetings comments
– COTW/Board approves Call for Public Hearing
• Continue development of Draft EIS based on Board direction
• Administrative Draft EIS will undergo Federal agency review
– All three agencies (FTA, FAA, FRA) will review for legal sufficiency prior to publishing for public review
• After public review of Draft EIS, staff will bring comments back to the DART Board for discussion and guidance on Final EIS approach
