Transportation follows development could be equally valid.
I'd like to address that, again. Development following transportation assumes people have a choice but do they really. Like I said, much of inner Boise is zoned R1 and R2 and is already mostly built out. There's not much for sale at any price relative to the total valley wide demand.
Due to the limited supply of land/housing in inner Boise, or any inner city, only one thing can happen and that's price goes up. A lot. So now we're faced with choosing increased density where it's allowed, which isn't a whole lot of places. I'd like to point out that nearly all our denser cities have higher housing costs. With the densest, like NYC and SF being the most expensive. So is density really a solution to housing problems? And SF City has severe construction limits.
One problem with increased density is that construction costs rise considerably. A few of the cost burdens are things like mandated fire walls, fire sprinklers, elevators, handicap provisions and a lot more, which are not mandated for R1 or R2 housing. Some infill housing depending on density incurs other costs mandated by the city such as paving the alley or completing sidewalks which aren't even adjacent to the property.
This isn't meant to be a $100,000 study on the issue, it's a quick look at what I see to be all the root causes of sprawl. Zoning laws and building codes and plain population growth really don't get enough credit, er, discredit. About 5000 a year graduate from TV area high schools and what-- 1300 or so from BSU and then there's the net migration to the area.
Remember also, as the radius of a circle grows the area of land contained within grows by a factor of πr^2. A one mile radius from the capitol contains only 3.14 sq miles of land. 2 mile radius contains 12.56 sq miles of land. 20 miles away from downtown contains 1256 sq miles. That's 20 times farther away but it contains 400 times the land area.
