Staff recommendation: Pilot project on 20-30 streets that applied for Neighborhood Speed Management projects, study other communities, study of crash data, public process
$102,500 in 2020
+$60K to install new signs in 2021
$65,000 cost total
Summer 2020 completion
TAB unanimously recommended this option.
$38,500 cost in 2020 for prelim work
Plus $60,000 to install signs in 2021 ($98,500 total)
Here's why: 9 of 10 pedestrians hit by cars going 20 mph will survive
At 40 mph, it's 1 of 10
We need wider change.
20 is Plenty is one of those things.
What would we study if other cities have already implemented this? They have real-world experiences; do we think drivers are Dif in Boulder and we'd learn something new?
Chuckles from Bill Cowern, transportation director. "Yes, we could do that, and it would be less expensive."
AND the design of the 20mph Vision Zero sign "had a variety of things built into it."
"It will be worth that $$ if you believe this is something we should do."
"We're not seeing a ton of speed-related crashes on residential streets," is his takeaway.
Neighbors will want cars to go slower; they'll come to the city and request other speed mitigation efforts that have been shown to work.
"These are not neighborhood tests; the bulk of them are just a block or two."
"Some of those streets are shorter in nature." BUT transportation is looking to study longer pieces of roadway.
But it does cost an awful lot, he says.
Noles: Not that I recall.
Cowern: There was one: In England. They "lamented spending their $$" bc it didn't lower speeds.
Noles: The citywide speed limit is 25mph, unless otherwise posted. On bigger streets with higher limits, it would require study and coordination with CDOT, in some cases.
Yes, Cowern says.
What would our enforcement plans be?
Young: Are enforcement costs included in these estimates we saw?
No, Cowern says: Not the costs or the revenue.
Weaver: So if we make these changes, we're going to be running a big experiment. We'll have something to compare to.
He'll support option 3: Do a pilot program now before lowering the limits citywide. "It's the cheapest cost in year 2020 in which we are in a financial crisis."
If there's no speed limit sign, the default speed limit is 20mph, just as it is now.
Damn, council and staff were SHOOKETH by that.
Cowern: It is a bit. I wouldn't take the signs down and leave the posts up with no sign; we'd have to take those down as well.
