STANDARDS
§ 152.275 STREETS.
(A) All streets shall be designed in substantial relation to topographic conditions and drainage; public convenience and safety; and proposed uses of land to be served by the streets.
(B) Except within a Comprehensive Plan Development District, a public street shall be provided for convenient access to all property within the subdivision and access to adjacent properties as may be needed.
(C) Private streets shall not be permitted, except when the subdivider submits sufficient evidence that there can be no public interest in the private roads or streets. The developer or owner is required to place road name signs at intersections in accordance with city regulations. All private streets shall be sufficiently illuminated to ensure the security of property and the safety of persons using the streets.
(D) The arrangements of the streets in a subdivision shall either provide for the alignment and continuation, or appropriate projection of existing streets in surrounding areas, or conform to an approved plan for the neighborhood which meets a particular situation where topography or other conditions make continuation of, or conformance to, existing streets impracticable. In any event, where a centerline offset (jog) occurs at an intersection, the distance between centerlines of the intersecting streets shall not be less than 150 feet.
(E) Streets that are extensions of or obviously in alignment with existing streets shall bear the names of the existing streets; however, no other streets shall bear names which duplicate, or so nearly duplicate so as to be confused with the names of existing streets. The street names shall be subject to approval of the Planning and Zoning Commission.
(F) Courts, dead-end streets or other arrangements may be provided if proper access is given to all lots from a dedicated street or court. All dead-end streets shall be developed as cul-de-sacs having a minimum radius of 40 feet of paved surface and a minimum radius of 50 feet of right-of-way. Dead-end streets shall not exceed 1,000 feet in length.
(G) The location of major streets shall conform to the locations designated on the transportation plan.
(H) The minimum width for rights-of-way shall be as follows:
Table 152.275: Minimum Right-of-Way Widths | |||
Type of Street | Description | Right-of-Way Width (Ft.) | Projected Avg. Annual Daily Traffic (ADT) |
Limited access road | Has the sole purpose of carrying traffic and provides no direct access to abutting properties | 100 ft. | >5,000* |
Major street | Primary purpose of carrying through traffic and secondary purpose of providing access to abutting property | 80 ft. | >5,000* |
Collector street | Collects traffic from streets that intersect and brings cars to major streets | 70 ft. | 1,500 - 5,000* |
Residential local street | Primary purpose is to serve abutting land use | 60 ft. | 100 - 1,500* |
* The ADT listed in this table are rough estimates and are not intended as design criteria | |||

§ 152.276 EASEMENTS.
(A) Utility easements shall be provided at the rear of all residential lots and along the side lot lines and shall be at least ten feet wide, and normally centered upon the rear or side lot lines; provided that transformers be located on or behind the front yard setback line. Evidence shall be furnished to the Planning and Zoning Commission that easement provisions to be incorporated on the plat or in the deed have been reviewed by the individual utility companies or the organizations responsible for furnishing the service involved.
(B) An unobstructed easement, not less than ten feet wide, may be required by the Planning and Zoning Commission through the center of blocks more than 900 feet long where deemed necessary to provide circulation or access to schools, playgrounds, shopping centers, transportation and other community facilities. Walking area must be paved at time of installation and a sign indicating the area as a pedestrian crosswalk easement is required.
(C) Where a subdivision is traversed by a watercourse, by a drainage way, channel or stream, or other body of water, appropriate dedications or easement provisions, with adequate width or construction to accommodate observed, computed or anticipated stormwater drainage through and from the subdivision shall be made. The width of the easement or dedication shall be dependent on the area of land drained by the watercourse but shall not be less than 15 feet wide to allow access for construction and maintenance equipment.
(D) Whenever any street planned to be continuous has been temporarily dead-ended awaiting subdivision of adjacent land, a temporary turnaround shall be provided by means of an easement which will terminate upon extension of the street. The dimensions of the turnaround shall be a minimum of 50 feet in radius.
(Ord. 10-3277, § 4-3.2, passed 1-4-2010)
§ 152.277 BLOCKS.
No block shall be longer than 1,300 feet between cross-streets.
(Ord. 10-3277, § 4-3.3, passed 1-4-2010)
§ 152.278 LOTS.
(A) Lots shall generally front or abut on a public street, unless:
(1) Otherwise approved as a part of a Comprehensive Plan Development District; or
(2) It is determined by the Director of Community Development or his or her designee that it is impractical to serve a single lot using a city street. In that case, a permanent access easement must be provided connecting a city street to the subject property.
(B) All lots shall meet the minimum depth, width and area requirements of the DO.
(C) The size, shape and orientation of lots shall be appropriate for the location of the subdivision, and for the type of development and use contemplated.
(D) Flag lots are prohibited.
(E) Depth and width of properties reserved or laid out for commercial and industrial purposes shall be adequate to provide for the off-street service and parking facilities required by the applicable zoning regulations.
(F) The fronting of residential lots onto major streets and highways is to be discouraged; however, where this does occur, the lots should be platted with extra depth and building setback to permit generous distance between the building and the traffic way.
(G) Excessive depth in relation to width shall be avoided. A proportion of two and one-half to one shall be normally considered as a desirable maximum for lot widths of 100 feet or more.
(H) Side lot lines shall be substantially at right angles or radial to street lines.
(Ord. 10-3277, § 4-3.4, passed 1-4-2010; Ord. 17-3538, passed 2-6-2017; Ord. 20-3609, passed 4-6-2020)
