Here's the list of unfunded segments, according to
the pdf:
Code:
CORRIDOR COST
I-225 to Aurora City Center $220m
SW extension $150m
SE extension $150m
Central extension $55m
North to 72nd Ave $245m
Northwest to 72nd exceeds available funds
Boulder BRT $168m
You can automatically cross off the NW line. I think you cross off the SW and SE extensions too, since those lines already extend far into the suburbs. That leaves these:
Code:
CORRIDOR COST
I-225 to Aurora City Center $220m
Central extension $55m
North to 72nd Ave $245m
Boulder BRT $168m
I'd rank them in this order of importance:
1. The North corridor is at the top since all the others have service on them already. This is the only corridor where the possibility exists for really screwing over the locals by not giving them anything. That would not be advisable.
2. The Central corridor is important from a system connectivity perspective, if nothing else.
3. The Boulder corridor will get good ridership, but the rail line is funded and existing RTD bus service to Denver is pretty good already. This is a hard line to cut. You could make an argument it should be higher than Central, but the presence of so much other stuff in the corridor means it has to be below North.
4. The I-225 extension is only getting you three more stations on an existing line. It's pretty comparable to the SE and SW extensions, and it's on a corridor that was never all that great to begin with. This one screams low priority to me.
Coincidentally, you can do my first two priorities for almost exactly the amount RTD has available, so I'd say do that. Use your $300 million to build the first segment of the North corridor and to finish the Central. Since there's not enough money available to build both North and Boulder, that makes the decision to pick Central over Boulder as the #2 priority easier.
