(A) Advantages of a property address numbering system. A street numbering system and corresponding property addresses provide individual structures with an exact geographic location in the county. City-type street/road addresses are necessary in order to provide a structure with a specific and more accurate identification for efficient mail delivery; to provide an easily identifiable geographic reference point for quick dispatch of police, fire and emergency rescue equipment; to provide utility companies with a permanent address record for billing and service calls tied to a specific structure; and to provide ease of location identification for friends, service vehicles or other individuals trying to locate a specific structure or a county road. A numbering system should make it easy for anyone to find the location of a county road or residential property in a short period of time and allow for a systematic expansion of address numbers as community growth occurs.
(B) The grid coordinate system. The county has structured the naming of its road system and the issuance of property addresses based on the Lyman/Purdue Street Numbering System. The system is better known as the Grid Coordinate System. The 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.
(C) County road names and numbers. Existing county road/street names will be retained, where feasible. Some names will have to be changed to correct duplications, multiple namings of the same road and other factors causing confusion. Road names will be used to delineate an assumed distance in feet from a base line or each other (grid line). All address measurements will be taken from the middle of an intersection.
(D) Property numbering intervals. Street addresses are assigned in increasing order from each base and grid line. In the county, 1,000 potential property addresses exist for each 5,280 feet (one mile) of distance from the base lines. There are approximately 50 address numbers that will be available for each side of the street/road within each tenth of a mile. All of those available numbers will probably not be needed, depending on the density of development along the street/road. Therefore, addresses occur at each 10.56-foot interval and block numbers change every 528 linear feet along a street/road. A specific street/road address is determined by measuring the number of 10.56-foot intervals between the nearest grid line or county street/road signpost to the front entrance of a structure. Crooked roads and roads running at angles (not true north-south or east-west) will be addressed with the predominant north-south-east-west direction. Distances between address numbers will vary in these cases.
