Does anyone know where I could find some inventory of on-street parking spaces? I'm looking for per city, or per neighborhood, or per street, or whatever data sources are out there for the Boston area.
Clearly on-street parking comes up all the time in fights about bike lanes, bus lanes, and new housing. My hunch is that in big parts of Boston/Cambridge/Somerville, there are only enough on-street parking spaces for a small minority (10-20%?) of housing units. But I don't know, and I'd be curious to see what the limits of that are.
And either way, since this gets fought over a lot, it'd be interesting to see some data.
I only know of datasets that encompass metered spots, not including the other types such resident only / loading etc. Granted, meter spots are usually the focus of the small business opposition crowd, but if you're looking for totals and resident spaces... Frankly, I'm not sure that the cities have an comprehensive inventory of those, especially since in my experience, resident spaces aren't really delimitated - people will tend to squeeze in and use the full available curb length as 3 Honda Fits take up the same space as 2 Chevy Suburbans.

That said... I needed to drive & park downtown today, (not by choice) and encountered several garages that were full. While off street parking in Boston is already expensive at ~$39 per day, true market determinant pricing should mean that price should increase when demand outstrips supply - yet it doesn't except for occasional event pricing. But it occurs to me that its possible to implement an ad-hoc proxy "congestion fee" through increasing the cost of parking by taxing it - we're rather alone amongst large cities for
not. I know
MAPC and the transportation funding task force suggested it before Healey shot it and other new revenues down, but Boston itself can do some of that via nothing more than adjusting meter pricing.
Meters are $3.75/hr in Back Bay and Seaport, $2-2.50/hr everywhere else. Compared to an off street garage that charges 40+ a day, 20 for a 1 hour stay yet is full, I'd contend that there's plenty of upwards space in downtown parts of Boston, especially if you also extend meter hours. Chicago's infamous meter privatization deal took street meters from $3 to $7, private garages pay 22% tax, and people still pay it. Boston last increased meter rates in 2019 - due to inflation, that $3.75 should at a minimum be $5 by now.
I know it's not politically realistic, but meters really should be priced similarly to private garages. Even not touching things like the public good that the street represents, they're substitute goods in econ speak; the "service" is functionally identical, and pricing should reflect that. If nothing else, it'll prevent some amount of VMT from people driving laps hoping for a meter to become available.
