Administrative Procedure #7.08 - Street Naming and Addressing Policies and Procedures

Street numbering within the current and future city limits, as expanded through annexation, will be based on a quadrant system of north, south, east, and west with the following street center lines being the dividing lines:

1. A line running east and west, following Monroe Avenue between the Willamette River and 26th Street and Orchard Avenue between 26th Street and the westerly projection of Orchard to the Urban Growth Boundary (UGB); and a line running north and south, following Highway 99W from the north limit of the UGB south to a point approximately 400 feet north of Polk Avenue, then running south-southeast to the Willamette River, then south to the Marys River, west to South Third Street and south along South Third Street to the UGB boundary.

Parcels in the City shall be numbered on a grid system. The system shall use the "baseline" streets as beginning points. The older central blocks shall maintain their 100-numbers-per-block system, with the remainder of the area being divided into one-mile grids. Each one mile shall be allocated 1,000 numbers which shall be divided into ten grid sections with 100 numbers per grid. The grid need not be rigid. Adjustments can be made to facilitate more appropriate breaks in the numbering system, with divisions between units of hundreds falling at street intersections.

The numbering shall be even numbers on the south and west sides and odd numbers on the north and east sides of streets. Exceptions should be made so that the system is continuous on a winding or circular street. For diagonal streets, the dominate direction is determined and the general rule is applied.

Building contractors shall be responsible for displaying temporary addresses visible from the street right-of-way during construction.

Street Naming

Street names shall be reviewed, approved, and assigned during the sub-division plat approval process. All proposed names for streets in the City shall be approved by the City Manager or their designee, who shall seek input from the Benton County Surveyor prior to final approval. No street name shall be used which will duplicate or be confused with the names of existing streets in the City, County, or surrounding emergency services area. Numbered streets will be reserved for streets running north and south. Those running east and west or diagonally will be named. Streets which provide access for more than four platted lots shall be named and signed. Naming shall occur at the time of platting.

Approved street names shall be limited to a length of 12 letters (excluding prefix and suffix) to facilitate use of standard signing materials. Requests for street names of a longer length must be approved by the City Manager or their designee.

Each street name will be preceded by the appropriate quadrant prefix, and the following suffixes are required to indicate the type of street:

• Street........................................... North and south
• Avenue........................................ East and west
• Way................................................... Diagonal 45 degrees or OSU
• Circle........................................... "U" or circular
• Drive.............................................. Meandering
• Boulevard.................................... Arterial route
• Place............................................ Cul-de-sac
• Highway................................................... Regional route

Private streets will have the designation (PVT) shown on the street sign following the suffix.

Street Name and Address Assignment and Changes

In accordance with administrative procedures, changes may be made in the street naming or addressing system when initiated by City staff to alleviate inconsistencies or irregularities or where it is found that there is conflict with another City or County street name.

An applicant requesting a street name change or address change when the above conditions are not met will be charged a fee to process the request as specified in the Corvallis Municipal Code Section 8.03.300.070. If the proposed change is in conflict with consistency or duplication criteria, the requested change will be denied.

Changes will be checked to assure consistency with the overall system and to prevent duplication between City and County. When processing a request for a street name or address assignments and changes, notification will be sent to the following affected parties for information and comment:

• City Manager and Mayor/Council (information only for street name changes)
• City Community Development Department
• City Finance Department, including City Services Division
• City Fire Department
• City Police Department
• City Information Technology Department, including GIS Division
• County Assessor
• County Elections Office
• County Records Office
• County Surveyor
• United States Postal Service
• Utility Service Providers, including telephone, cable, electricity, gas, and solid waste

Comment to City staff shall be provided not more than 15 working days from the date of notification.
