The planning commission, in numbering the houses and buildings upon the streets and thoroughfares of the city, shall adhere to the following:
A. Initial Point Of Intersection: The initial point of intersection in the citywide grid system shall be the junction of Toquer Boulevard (meridian street) and Center Street (baseline street) in the city, and the numbering shall extend thence east, west, north and south. Address numbers shall be even on the north and west sides of the street and odd on the east and south sides of the street. One hundred (100) numbers shall be assigned to each identified grid block with the lowest number beginning at a point nearest the initial point of intersection in the citywide grid system. Address numbers shall be determined by the number grid in which the property is located. Address numbers in central areas with no grid shall be assigned in relation to adjacent addressing.
B. New Residential Subdivisions: In new residential subdivisions, each standard sized lot shall be given a preassigned street number by the planning commission upon final plat approval. Address numbers shall be assigned to large lots relative to their capacity to be subdivided into two (2) or more minimum sized lots for the minimum width allowed by the zoning district. In commercial areas, addresses will be assigned as development plans for those lots are approved, prior to building permits being issued.
C. Calculation Of Address Number: Address numbers shall be determined by calculation. The distance from the center of the property to the last corner of the citywide grid shall be measured to get a thoroughfare number. The thoroughfare number is then added to the block number to get the address (i.e., if the block number is 1200 and the location number is 43, the address is 1243 or 1244, depending upon which side of the thoroughfare the building is placed. In other words, the address is the percent of the total distance into the block, plus the block number).
D. Series In Thoroughfare Intersections: When thoroughfare intersections are within one hundred twenty feet (120') of a grid line, the number series change shall be made at the intersection to be more logical to the public. When a long block faces two (2) blocks divided by a street or thoroughfare, the number series on the long block shall change at the intersecting street or thoroughfare so that houses or buildings facing each other have compatible addresses.
E. Diagonal, Curving Streets: Diagonal streets which run forty five degrees (45°) or less from a north/south line will be numbered by the north/south grid, and those more than forty five degrees (45°) from the north/south line will be numbered by the east/west grid. Curving streets will be assigned numbers based upon the grid of their greatest length. For instance, if the beginning is more south than west of the end, then the north/south grid will be used.
F. Loop Streets, Thoroughfares And Cul-De-Sac Streets: On loop streets and thoroughfares and cul-de-sac streets, address numbering shall begin at the entrance nearest the initial point of intersection within the citywide grid system and increase to the opposite end as if the street were in a straight line. Block number changes will be made every three hundred thirty feet (330'), with odd and even number remaining on the same side of the street as they began.
G. Apartments:
1. Apartment buildings on thoroughfares shall be assigned individual addresses. Apartments clustered about a central parking area immediately facing a public street shall also be assigned separate addresses.
2. When apartments are arranged along a private street or thoroughfare, addresses can be assigned from this private street or thoroughfare. A sign showing the apartment complex name, with the street address below it, must be posted at the entrance.
3. Each apartment must be identified on the exterior entrance by number or building letter and number for multiple buildings. The numbers shall be in sequence (i.e., 1, 2, 3, etc.). Apartments in lettered buildings shall have the building letter as part of each apartment number, such as B-210. When units are on multiple floors, ground floor numbers shall be in the 100 series (101, 102, 103), second floor numbers shall be in the 200 series (201, 202, 203), etc. If a common hallway is used for several apartments, the external hallway entrance to each apartment shall contain a list of the apartments served. When addressing townhouses and other buildings containing units separately owned, each address shall be placed on the principal external entryway to the unit.
4. The official address for each apartment shall be the building address, as described in subsection G3 of this section, followed by the apartment number (for example, "223 Greenway Dr., Apt. 3"). Addresses for units in apartment buildings not on a public thoroughfare shall include the public thoroughfare address and the building number with the apartment designation. The official address for each apartment will be the public thoroughfare address followed by the building letter, a dash and the apartment number (for example, "223 Greenway Dr., Apt. B-111").
H. Mobile Home Parks:
1. When trailers are arranged along a private thoroughfare within mobile home parks, each private thoroughfare within the mobile home park shall be named and a sign, as required by this chapter, shall be erected on each private street within the mobile home park.
2. Each mobile home on such a private thoroughfare shall then be identified in numerical sequence as determined by calculation, as described in this chapter. The number shall be placed in a conspicuous place on the part of the trailer closest to the thoroughfare, and all mobile homes within the mobile home park shall be marked in the same location of the trailer. Address numbers shall be a minimum of three inches (3") high with block letters and shall be visible from the street. All other provisions of this chapter on the installation of identification numbers shall be applicable to mobile homes.
3. It shall be the requirement of the mobile home park owners, who are registered with the city, to make sure that each private street within the mobile home park is properly named and such name shall be approved in advance by the planning commission or its designated representative, and it is further the responsibility of the mobile home park operator to make sure that each mobile home is properly addressed and the number posted as set out in this chapter.
I. Commercial Or Office Buildings:
1. Commercial or office buildings on public thoroughfares or private thoroughfares shall be assigned individual addresses. Commercial or office buildings clustered about a central parking area immediately facing a public thoroughfare shall also be assigned separate street addresses.
2. When a commercial building or office building complex is arranged along a private driveway or around a private parking area, the complex shall be addressed off the public or private thoroughfare serving the complex.
3. Each suite or unit in a commercial or office building must be identified on the exterior entrance by number or building letter and number for multiple buildings. The numbers shall be in sequence (i.e., 1, 2, 3, etc.). Suites or units in lettered buildings shall have the building letter as part of each suite or unit number, such as B-203. When units are on multiple floors, ground floor numbers shall be in the 100 series (101, 102, 103), second floor numbers shall be in the 200 series (201, 202, 203), etc. If a common hallway is used for several suites or units, the external hallway entrance to each commercial or office building shall contain a list of the suites or units served.
4. The official address for each commercial or office suite or unit shall be the building address followed by the suite or unit number (for example, "223 Greenway Dr., Suite 3"). Addresses for suites or units in commercial or office buildings not on a public thoroughfare shall include the public thoroughfare address and the building number with the suite or unit designation. The official address for each suite or unit will be the public thoroughfare address followed by the building letter, a dash and the suite or unit number (for example, "223 Greenway Dr., Suite B-2").
J. Content Of Identification: Each property identification number must contain:
1. A frontage number component which is numerically sequenced and assigned to a structure or parcel according to subsections A through H of this section;
2. A direction component referencing the city grid quadrant and the compass direction in which the frontage numbers run, abbreviated with the single letter equivalent for its compass direction (N, E, S or W);
3. A thoroughfare name component consisting of either an alphabetic name or a number name, but not both;
4. Thoroughfare type component, which modifies the name to distinguish specific locational, functional and physical characteristics of the thoroughfare;
5. A unit, suite, apartment or mobile home locator component if required by subsections G through I of this section. (Ord. 2008.02, 3-13-2008, eff. 3-13-2008; amd. 2014 Code)
