Just mandate all new builds have a parking garage under them. Seattle is my closest big city which has notoriously bad public transit, extremely steep hills, bad and wet weather most of the year, and parking 20 minutes walk for your location is very very common. I used to be disabled, used portable oxygen and the lack of parking combined with these other things essentially made the whole city off limits to me. People like to call others lazy, entitled or stupid for wanting parking but having adequate accessible parking is a real issue that impacts more than just able bodied people. Even some medical clinics don’t have on sight parking. Accessible parking is part of a socially responsible plan for inter city transportation.
