Why are DART representatives presenting material like exhibit 1 which shows that betterments and mitigation go all the way (or almost all the way) to the intersection when they've known about this limitation? Don't you think a resident would have been upset if they voted on a betterment wall and at installation time see a chain link fence was put up?

A: The exhibits are identifying the limits of the betterment walls defined by residential adjacent property lines at the 10% level. The details related to the specific configuration at each at-grade crossing is a final design issue. DART is working with the design build team to optimize the limits of the betterments wall near the at-grade crossing and comply with safety requirements. This design activity will include review of equivalent measures that may be available as an alternate to the required sight distance.

There have been numerous betterment meetings that have been restarted because of lack of communication, the entire 1st round of 5 meetings. When, if ever, was DART going to notify those Residents that live within the estimate distance from an intersection (TBD based on DART calculations), that they will get a chain link fence instead of a wall?

As noted in the response to question No. 1, the details related to the specific configuration at each at-grade crossing is a final design issue and has not been defined. It is premature to reach the conclusions cited above regarding a chain link fence. DART will not suggest a chain link fence instead of a wall.

At what distance from each of the intersections from Preston Road to Coit, will the betterment or mitigation walls start? There are 8 crossings. We need the distance for each corner of the 8 crossings or 32 distances. This will need to be calculated and communicated thoroughly to all the residents that live in these unique situations. The longer this is delayed, the more jarring this will be for residents in Far North Dallas.

As noted in the response to question No. 1, DART is working with the design build team to optimize the limits of the betterments wall or sound wall near the at-grade crossing and comply with safety requirements. This design activity will include review of equivalent measures that may be available as an alternate to the required sight distance. For the next round of betterment meetings in July, DART will show the in-progress design for at-grade crossings.

There are now some residents who will not receive a mitigation or betterment wall based on the resident’s findings. This impacts the number of people per group and per segment that have to vote. Does this mean we have to restart the Group 1 meetings, 5 meetings for 5 groups, again (2nd time) since the number of people in each group has changed?

No. The number of residential adjacent property owners will not change.
