Addressing

    What Is Site Addressing?

    Site addressing is the system employed to assign a unique identifier, typically a street number, name, or code, to a property, building, or parcel of land. This official address serves as a crucial means of identifying the physical location of a site.

    Why Addressing is Important

    Local governments or municipalities generally implement site addressing for a variety of essential purposes, including:

    • Emergency Services - The prompt response of police, fire departments, and ambulance services depends on precise geographical data.

    • Utility Services - Essential services such as electricity, water, and internet require specific addresses for installation and ongoing maintenance.

    • Mail Delivery - Accurate site addresses are necessary for postal services to ensure effective and reliable delivery.

    • Property Records - Accurate addressing is vital for the management of taxation, zoning regulations, and property deeds.

    Promote Uniformity

    Use a uniform property identification system to describe locations throughout community.

    Improve Services

    Help public safety and other government agencies quickly respond to calls for service.

    Locate Destinations

    Facilitate the location of structures, properties and destinations for residents and visitors.

    Having your address easily visible at the end of your driveway AND on your home will ensure that first responders are not left wondering if they are at the right location. Be sure to follow the Mat-Su Borough Code 11.20.060 on address posting requirements. Police, Firefighters, EMS responders cannot provide services to you or your family if we cannot find you.

    Address Assignment

    Addresses are assigned to new developments during the development review process, before construction begins. For more details about the specific guidelines and procedures, refer to Borough code 11.20: Street names and address numbers.

    What is the process? 

    As land in the Mat-Su Borough gets developed, it is common for larger properties to be subdivided during the borough platting process. Once the development meets all the requirements outlined in the subdivision construction manual, it is recorded with the state of Alaska. After the new development is recorded, the borough can assign site addresses to the new lots.

    Additionally, any new lots that access a borough right-of-way must apply for a borough driveway permit. This requirement is especially important for corner lots or lots with road frontage on multiple sides, as the address must be assigned based on the road that provides access to the property.
