Know Before You Go, Part 3.
Part 3 of 3: Grant County Cartography
To help locals and others understand the addressing of unincorporated Grant County, here’s the third of three cartography (map) lessons. This is especially helpful for those who may be new to Grant County.
This third lesson helps explain distance and addresses east to west from Division. Each mile is represented by a letter that coincides with its sequence in the alphabet. For instance, Road A (the first letter of the alphabet) is one mile from Division. Road B (the second letter of the alphabet) is two miles from Division. Road B.5 is 2.5 miles, Road B.7 is 2.7 miles, and so on.
This numbering will help determine the address of a home or business on a north-to-south county road.
• Division = 0 (zero), addresses between Division and Road A are 0-999
• Road A = 1 mile, addresses are 1000-1999
• Road B = 2 miles, addresses are 2000-2999
• Road K.2 = 11.2 miles, address 11200 (K is the 11th letter of the alphabet)
So, to put it all together:
• 26212 Road A NW is about 26.2 miles north of Baseline. (Baseline represents zero, so the farther north or south you go from Baseline, the higher the numbers become).
• 5206 Road 12 NE is about 5.2 miles east of Division (the 5000 block because E is the fifth letter of the alphabet). Division represents zero, so the farther east or west you are from Division, the higher the numbers become).
Incidentally, the furthest west county road is Road Road Y.5 SW in Sunland Estates. The furthest east county roads are Road X NE east of Wilson Creek and Road X SE east of Warden.
The outliers in this plan are roads that are named and not numbered. Named roads include Martin Road NW, Lazy Acres Road NW, Potato Frontage Road SE, Adams Road NW and SW, and many others.
Roads like Adams Road that run north to south have numbering based on the distance from Baseline (explained in Lesson 2).
Roads like Martin Road NW run east to west, so numbering is based on the distance from Division (explained in this lesson).
Named roads can be almost anywhere in the county. Perhaps the easiest way to find the location of an address on a named road is to consult an app such as Google Maps.
