When progressives can be really "flawed"
(Flawed = the other F word)
One of the things that people don't seem to understand is that newly constructed housing is always more expensive than extant housing, because it is new and cost more to build at today's prices than did comparable housing constructed decades ago. From the article:
Nearly 1,000 new apartment units have been constructed in the Columbia Pike corridor over the past three years, all significantly more upscale than what has been seen in the corridor in the past. So far, the new development has been in addition to - not in place of - existing housing units.
The point is to deal with this reality, rather than try to keep our heads stuck in the sand. I can't claim to be an expert on housing supply, but the proscriptions for maintaining access to lower cost housing stock aren't difficult to figure out and provide. Trying to not add better transit won't do anything in terms of "warding off" intensification of land use and increases in rents and the conversion of rental housing to owner-occupied housing. Here are some possibilities:
Note that these are the same issues faced by Langley Park/Takoma Crossroads in the face of the coming of light rail there. See "Crossroads community in cross hairs for developers, immigrant advocates: Immigrant groups fear gentrification along Montgomery-Prince George’s line" from the Gazette.
