The article says the city claims the biggest issue is federal regulations (the ADA) not city regulations.

My neighborhood in NJ just got those fancy ADA compliant curb ramps last year, along with a repaving. It did take them much longer to install the curb ramps (like a week or two?) than it did to pave (one day) so I can imagine there is a significant cost, even if it's a smaller amount of materials.

One wonders if you could prefabricate kerb ramps and drop them in, rather than (I assume) casting them in place.

Maybe they'd settle badly if vehicles drive over them, kick up in the opposite corners and become a trip hazard.

The UK mostly skirts this by using tarmac and paving slabs instead of concrete.

I don't think there's a way to do this without casting something to connect the pre-fab to the surrounding concrete sidewalk. Like how do you precisely cut out the existing curb so the prefab just fits (including elevation/slope) without excessive gaps or something? And if you're pouring concrete anyway, might as well pour the curb itself.

Or make the asphalt "ride up" onto the sidewalk itself, so the complicated part is made of asphalt.

Likely this won't be terribly faster, and I did see the company near us using a machine that was building curb cuts directly.

Very few sites are going to be flat or square. I suspect prefabbed parts mostly wouldn't fit without custom adapters around the edges.

Damn. I've been curious what the deal is with the rubber lego knob coverings on sidewalk ramps and here it is. I mostly notice because they're such hell for skateboarding, so it never occurred to me they'd be an ADA thing as I assume they're equally hard to navigate in a wheelchair, but apparently the idea is to provide a tactile warning that the street is nearby for people with vision impairments.

Why do you think so? Even the front wheels of wheelchairs are much larger than those of skateboards, and their main wheels typically are pneumatic (front ones, too, probably, but cheaper ones might skimp on that)

"Be hell for skateboarding" wasn't likely considered a bonus by the disability people because it would rally "those sort of people" to their (otherwise legitimate) cause.

According to the cdc 1 million.people are blind and 7 million people have serious vision impairment.

It would be cheaper to pay 60k a year per blind person to hire them a full time guid for waling outside.

Ok, but curb cuts also positively impact wheelchair users, people with canes or walkers, people with injuries that require crutches or a knee scooter, parents with strollers, people with rolling bags, cyclists, delivery workers and more. They are widely understood to benefit many many people beyond just people with disabilities (so much so that their benefit has given a name to the "curb cut effect").

Also, $60k/year is a) not nearly enough to pay a contractor full time living wage and b) not enough to cover the greater than full time necessary to assist someone. Blind people need to navigate the world at all hours on all days...
