The Fundamentals of Addressing II Rural
Addressing Systems

What is anAddressing System?

• An Addressing System is an overall guideline for
  assigning addresses across a broad geographic
  area.
• The two most common addressing systems are
  variants on Equal Interval and Grid addressing

3
What is Equal IntervalAddressing?

• Equal Interval Addressing is addressing based on
  linear distance driven on a specific road.
• Low potential address on road is usually 1
• Addresses increment by a known, set interval
  (usually 100 or 1000 per mile)
• Sometimes called odometer-based addressing or
  distance-based addressing

4
What is Equal IntervalAddressing? cont

• EIA is appropriate for any road network but is
  recommended especially for irregular road
  networks
• Road Names or Numbers are possible
• Address does not convey where in county resident
  is located but does convey how far along road
  resident is located
• Generally results in lower (smaller) address
  numbers and easier-to-remember addresses

5
What is Grid Addressing?

• Grid addressing is addressing based on a regular
  grid overlaid on the county, usually following
  section lines
• Low address per road is based on road origin
  related to position on grid
• Addresses increment by a known interval per grid
  line (usually one mile) as the crow flies, not as
  the road is driven
• Road segments broken at grid lines as well as at
  intersections

6
What is Grid Addressing? cont

• Grid addressing is most appropriate for a gridded
  road network that is generally based on section
  line roads
• Best with gridded road numbers/can be used with
  road names

Equal AddressingRoad Origins

• Every road is assigned an origin (where low
  numbers originate) based on addressing guidelines
  established for county
• From major road to minor road
• From south to north/west to east (or similar)
• From closer to ZIP Code city of origin
• From center of county outward or from chief city
  in county outward

Grid AddressingRoad Origins

• The grid itself has an origin and roads take
  their low/high ranges from position on the grid.
  Grid origin is usually in a corner of a square
  made by drawing a rectangle around the county but
  can be in them middle for quadrant addressing.

Grid AddressingRoads off the Grid

• In grid addressing, all roads must be designated
  either north/south or east/west
• Designation can be made on rise over total length
  of road OR on direction at start (low end) of
  road

What do Addresses Mean(in a true grid)

• In true grid, road numbers are meaninful
• Addresses interpret houses position relative to
  the grid (and thus road names)
