I can never get enough Donald Shoup. Here are some policies he suggested at a recent talk in Philadelphia:

• parking benefit districts, where parking revenues go to street and pedestrian improvements, so people can see what they are paying for
• parking permit blacklists – essentially, people who move into new buildings without parking are not allowed to apply for city parking permits. This might seem unfair, but in my neighborhood in Philadelphia one way existing residents are able to hold up new development is by raising parking concerns with their elected politician. So this could be politically practical in that it might remove one of the sticking points between long-established residents and newcomers. At least, alleviating this one concern might allow people to move on and tackle others. It would force the new developments to either provide onsite parking, or just develop in places and ways where people are not going to demand as much parking. You could drop any minimum parking requirements and let the market decide.
• Parking cash-out – employees who choose not to use company-paid parking can opt for a cash payment instead. California has done this apparently and it makes sense to me. It removes a perverse incentive for some people to choose driving to work over other options.
