The city is introducing changes to the neighborhood Residential Parking Zone program this year. Come March, it will be easier to check if you need a parking permit on your block and apply for a permit online. Newly issued decals include the registered vehicle’s plate number, assisting in parking enforcement. (Existing permits will continue to be valid through their expiration date.) Which vehicles must be registered, the number of single-day guest permits, and the number of permits allowed per address are changing as well. No permit will be required for motorcycles and scooters, but a couple of challenging restrictions are coming: no more than four permits per address, and vehicles must be parked within six blocks of the registered address. More information on the 2010 RPZ program changes is available from seattle.gov.
