A few folks have informed us that the City of Columbus is not mailing residential parking permit renewal forms to University Area Districts such as the "NK" parking district this year. Instead, residents are required to go to the City's Service Center to purchase the permits. Apparently, the new approach is to cut down on permits being issued to former residents.
The current permits expire on 9/30, so if you depend on one, you'll need to go for a new one soon.
Here's the link: http://columbuspvb.com/Residential-Parking-Permit.htm
Please note that the facility is open Saturday from 9 a.m. - 7 p.m. You'll need $25, a driver's license, your car registration, and some proof that you live in your house (i.e. utility bill, mortgage statement, etc.). The website also has more info and a form you can fill out in advance.
Good luck!
PS The info will be up on http://www.necko.org as well, so feel free to forward or share!
