The numbering of the road system and the issuance of property addresses shall be based on the “Grid Coordinate System”. The grid coordinate system utilizes two base lines which run at approximate right angles to each other to divide the county into quadrants. Most of the county roads are numbered based on their distance from the north-south and east-west base lines. Each mile portion of roadway becomes a “block” for uniform numbering purposes. Specifically, the following standards shall be employed.
(A) Grid lines. The general shall be 1,000 addresses per mile, except in certain areas where the direction of the county roadways makes variations necessary. Beginning from the point of origin a house number shall be assigned for each interval, with each interval on the right side of the roadway as one leaves the point of origin being assigned an even number, and each interval on the left side as one leaves the point of origin being assigned an odd number. Left and right shall be determined from the perspective of a traveler moving away from the road point of origin in a forward motion.
(B) Street addresses. Street addresses are to be assigned based on a measurement of the distance from the nearest grid line to the main access way or drive to the structure. A structure shall, whenever possible, be addressed to the street or road where the main access way intersects.
(C) County road numbers and names. Existing posted county road numbers or names will be used to delineate an assumed distance in feet from a base line or each other (grid lines) even though a true measurement to the road is not exactly the distance stated on the road sign. All address measurements shall be taken from the middle of the intersection.
(D) Property numbering intervals. Street and road addresses are assigned in increasing order from each base and grid line. In general, 1,000 potential property addresses shall be allowed between each grid line.
(E) Determining a property address. As a general rule, an official street address shall contain no more than five digits with the first digit [or the first two digits if the structure is located ten or more miles from the baseline] indicating the milepost or distance from the base lines. The second or third digit shall indicate the block number, which will change each 528 linear feet. The last two digits indicate the number of 10.56-foot intervals from the structure to the nearest block or grid line. Deviations from the general rule may occur to take into account variations in section grids.
