City sewer and water came in and the people were still living in the house at that time. They have since moved the house and sold the lot. Original address: 16220 Northwood Road Annexed in 2004 and became 2956 Hawk Ridge Road Bluffs of Northwood plat approved in December of 2006: 16046 Tahinka Place 411 Lynda S.

This subdivision created a new street called Hawk Ridge Road NW, which provides access to your property located in Spring Lake Township, which was previously accessed via a private drive from Northwood Road. The public street, which serves your property, has changed and it is necessary to change your address. Your new address will be: 2956 Hawk Ridge Road NW I realize the inconvenience that changing an address can cause and I apologize for this. My primary concern is in providing the most efficient emergency response possible. To do this it is necessary to change your address. Please change your records to reflect this. You will also need to inform your telephone company and post office of this change. (The telephone company and post office will only accept this address change when contacted by the customer.) Please call me if you have any questions.

ISTS applications are valid for one year, unless an extension is approved by our office. Our records indicate that an ISIS has yet to be installed on your property. If you still intend to install an ISIS please contact our office by December 15, 2000 for an extension. We will void your permit after this date if you have not received an application extension. This means that you would have to reapply and pay the permit fee again. If you have any questions or concerns please feel free to contact me at (952) 496-2265.
