Current local parking example is a new apartment block - ~500 units, ~800 spaces required, developer thinks ~600 is enough because the building is adjacent to a subway stop and across the street from a massive mixed development. This is an area with almost zero on-street parking - there's no risk of tragedy of the commons here because there's no street parking to "steal". Why is the county requiring more parking than the market value? The developer has no incentive to under-build parking - nobody would rent in the building if there wasn't enough parking available. Edit - Des Moines has 19.4 parking spaces per household. Seattle has >5 per household.
