I would like to limit the amount of surface parking at a yet to be built hospital campus. The site is currently undeveloped and does have natural constraints to development. Neverthess I don't want to wait until the land under the cars becomes valuable enough to warrant structured parking so additional development can ocurr where the parking is (will be). Ideas I have include bonuses against impervious area requirements and outright limits. Does anyone have any ideas or experience in forcing structured parking?
