Briefing on the Cotton Belt Corridor

Committee-of-the-Whole

November 28, 2017

Chad Edwards, AVP Capital Planning

1

• 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

• 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

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

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

• 25 crossings advanced to LOS and queue impact analysis

– 13 crossings identified as ITE category 2 or 3 require additional analysis

– 12 additional crossings identified for analysis based on proximity of nearby intersections to rail crossing:

o East Belt Line, MacArthur, Luna, DNT Frontage Roads (2), Davenport (2), Hillcrest, Alma, PGBT Frontage Roads (2), K Avenue

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

F >50 >80

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


69

Equipment Maintenance FacilitySite Inventory (2012)

70

• 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

Relocation of Mercer Yard

72

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

Station BackgroundNCTCOG Conceptual Engineering Study City Coordination Efforts (2009-2010)

• Based on prior feedback, DART has continued to assume only one station in Carrollton

77


• Richardson supports moving Custer to UT-Dallas Station and connection with CityLine/Bush

78


• Addison concerned Knoll Trail and Preston are too close for regional rail application

79


• City of Dallas supports stations contained in 2006 resolution

• Supports Coit Road Station location
