4 Things You Need to Know About D2: Working Together

We need your input and support as we continue planning D2. A subway presents a unique set of challenges we will have to work through to make the best use of our resources, balance everyone’s interests, and position the downtown Dallas and North Texas communities for success. We will all need to work together to achieve the best possible outcome.

#OurDART needs input from the entire region as we continue project development for D2.

Why does your help matter to D2?

Public transit systems are built to serve the entire community. It’s important that everyone who uses and is affected by the DART system contribute their feedback on the D2 subway design.

Usability: D2 will be the underground second rail alignment built to alleviate the current bottlenecking of rail transit lines in downtown Dallas.  We want to hear from you about how the design of this alignment would best serve the greatest number of people — both riders and non-riders alike. As DART refines the route of the Locally Preferred Alternative (LPA), we need input on everything from route placement to station locations.  DART’s goal for D2 is to make sure everyone is able not only to use the system to get to where they need to go efficiently and affordably but also to benefit from the system even if they don’t use it regularly themselves.

Safety: Underground transportation can present unique safety concerns. In addition to ensuring the safety of the subway, cars, tracks, and movement underground, DART wants to make sure everyone is safe to ride D2 no matter what time of day it is. The community can help DART keep D2 safe and secure by raising awareness if there are areas of the system that may require greater security than others.

Underground obstacles: We may not realize it, but there are more things underneath our feet than just soil or rock. Cities like Dallas have all sorts of infrastructure underground that helps us live our daily lives.  Pipes delivering natural gas, building foundations, underground parking garages and electric utility lines will all be obstacles DART will have to work around as the construction of D2 begins.  Having input from experts in these areas will be critical.

The key to D2’s success is collaboration and feedback from the public, stakeholders, policy-makers, and technical staff.  Together, we can make sure #D2will be a successful transit solution for our region.

    I am a supporter of DART moving forward with the D2 Line Section as a critical element in keeping the overall system operational in the event of a downtown line shutdown. D2 can also serve to promote future downtown transit-oriented development in southern downtown.

    Usability: To maximize D2’s value it should provide connectivity to the exisitng downtown convention and hotel developments, to the growing downtown urban residential developments, evolving downtown higher education centers, and to future points of multi-modal connectivity.

    Safety: Dallas citizens are generally unaccustomed to boarding mass transit 50Ft underground. With growing public concern about terrorism, and the media’s constant promoting of confrontation and disregard for law enforcement, the underground D2 Line should portray and be designed as a safe environment. Underground spaces should be bright and visually interactive, possibly incorporating natural illumination via vertical light shafts. The stations should be well-monitored, provide a sense of passenger security, and be well provisioned for emergency.

    Underground obstacles: The Underground D2 Line is expensive and will involve issues with existing utilities, surface traffic, and protection of adjacent building structures due to the deep excavation occurring between them. This could all translate to high levels of liability exposure for DART and its design/construction teams.

    Side Note …

    In contrast, a Surface D2 Line, though less expensive still involves issues with utilities, surface traffic, and supposedly noise at certain locations. An Elevated D2 Line seems to be a compromise expense-wise, with less impact to utilities and surface traffic, but apparently some concern expressed by downtown building owners over its visual and noise impact; both of which are largely addressable through design. A well-designed elevated line could in fact become a visual asset, incorporating such elements as architectural lineal screens/enclosure systems, catenary supports, stations canopies, and providing opportunities for elevated pedestrian walkways/bike paths, lineal green spaces, pocket parks, retail kiosks, and elevated connectivity to future adjacent developments. Property owners of Downtown Dallas may be unaware of examples that exist globally of elevated rail lines in high density urban areas, some of which incorporate these same features and amenities.
