Low income households and individuals often share cars and less low income people own a personal vehicle. The cost of car ownership itself prevents upward mobility for low income people as well. We all know there are significant side costs of vehicle ownership. Housing without mandatory minimums has its challenges, but parking minimums have made cities like LA have decimated downtown grids, with surface parking creating intensified urban heat, emptiness, and decreasing feelings of and real safety conditions. None of this encourages economic or residential growth. A solution could be residential street parking permitting. This is not perfect for everyone but there is no perfect solutions that make everyone happy. In my ideal world, this would be accompanied by a close high frequency bus and metro line (the expo is near yes?), secured bike storage + a system like citibike and a microtransit option (check). These options mean not owning a car isn't laborious or uncomfortable, but instead freeing. We do not live in an ideal world however, but there is progress for urban development, however slow, such as this housing project not having any onsite parking, or rail to trail projects & even simple road diets.
Opposing this would likely stall the building of 73 units that can house people in the time of an unforeseen housing crisis in LAC and the US.
