I'm fairly confident they will not build low income housing.
I think you should do some research then. Being a semi-local, Measure LC is only a temporary reprieve from future developments, and the park that is proposed would be temporary until they rezone the area, and there is a HUGE push in Santa Monica right now for affordable housing, since nearly none exists. There was a proposal that was out there (I can't find it, but I'm still looking) that was put forth by the city counsel a few years back for low income housing. Then, a few people came up with the idea of "well, let's build a park! Maybe that will go over better than housing. We'll call it 'Measure LC' and let the people vote on it!" I've been following this for ten years now. Trust when I tell you that a park site would only be temporary. They "need" low income housing much more than they need a park. Santa Monica is ripe with places for recreation. The beach and parks are only minutes away from any spot in the city by bike, car, or rail. I live out this way, I speak from experience. This rodeo has become old and tiresome. Bill Dunn (AOPA) had almost an entire tenure with AOPA before he finally retired recently, defending keeping the airport open.
These low income housing proposals, if memory serves, were put forth circa '12-14. Then, Friends of Sunset Park got involved in the mess and everything changed, for the short term. These guys are a bunch of NIMBY's, that will say whatever they want, to get what they want.
They want low income housing, because they will get a big chunk of state money if they build it. They took $250k in federal money that they are considering paying back so they can take $1.2m in state money for the proposed development. (this is all from memory, and like I said, I am looking for the link)
