The Clatsop County Transportation & Development Services prepared the following 2010 Addressing Guide with assistance from the Clatsop County Sheriff's Office. Although initially designed to meet the needs of emergency responders, this information will be useful to anyone attempting to locate a rural address. This guide is made available through many County departments in printed format or online at www.co.clatsop.or.us.
Clatsop County’s Rural Addressing System is based on a premise of using dedicated road names coupled to numbers derived from the State’s Plane Grid Coordinates. With the exceptions of highways, loops, drives and courts, if a roadway runs primarily east and west, it will be labeled as a "Lane," and if it runs primarily North and South it will be labeled as a "Road."
Address numbering for north-south roadways range from 77200 at the county’s Southern border to 95300 at the Northern border. When traveling north along these routes, odd numbers will appear on the east side of the road and even numbers on the west side (does not apply to Loops). Consequently, address numbers on East/West roadways running West to East will range from 31800 furthest West to 49400 on the County’s Eastern border with odd numbers appearing on the North side of the roadway and even numbers appearing on the South side.
All directions in this guide are given from the nearest State highway. This guide relies heavily on established milepost markers (MP) in the directions. On State highways (Hwy), mile markers vary as to their point of origin depending on where the highways originate. Due to road realignment, some milepost markers have been eliminated. This has occurred on Hwy 101 where markers 11 and 12 have been eliminated and the distance from marker 10 to 13 is approximately 1 mile. Also, markers 90 and 91 on Hwy 30 have been eliminated and the distance between 89 and 92 is approximately 1.1 miles. Mile markers for County roads generally begin at their origin from a State highway and, in the case of a loop or interconnecting road, the origin is usually at the point nearest to Astoria.
Zones listed in the Guide are primarily for law enforcement use but may be helpful to you in identifying general areas of the County.
- Zone 1 is the Northeast portion of the County and is accessible by Hwy 30 and includes those communities from Tongue Point to Westport.
- Zone 2 is the Northwest portion of the County and includes the communities of Astoria, Warrenton, Clatsop Plains, Gearhart, Lewis and Clark and Olney.
- Zone 3 is the Southwest portion of the County and includes Seaside, Cannon Beach, Hamlet and Hwy 53.
- Zone 4 is the Southeast portion of the County and contains the communities of Elsie, Jewell, Fishhawk Lake and Birkenfeld. Run numbers reflect those addresses which can be found on that roadway.
