(A) The street layout shall provide access to all lots and parcels of land within the subdivision. Street jogs at intersections of less than 125 feet shall be avoided. Street terminations in a cul-de-sac shall not exceed 700 feet in length unless necessitated by site topography. The measurement shall be taken from the center of the closest intersection that allows two or more alternative access routes from the entrance of the subdivision to the center of the cul-de-sac.
(B) Local or marginal streets shall be designed by pattern and layout so as to discourage through traffic unless otherwise noted in the Comprehensive Plan.
(C) Proposed streets shall be adjusted to the contour of the land so as to produce usable lots and streets of reasonable gradient.
(D) Proposed streets, where appropriate, shall be extended to the boundary of the tract to be subdivided so as to provide for normal circulation of traffic with adjacent existing or future subdivisions or developed areas.
(E) Wherever a dedicated or platted portion of a street or alley exists within the proposed subdivision, the street or alley shall be platted to the prescribed width within the proposed subdivision unless such use is vacated.
(F) Widths of interstate highways, major and minor arterials, collector and local street rights-of-way shall conform to the widths specified in the typical right-of-way sections provided herein. These widths may be increased or decreased or varied in unusual circumstances by the Planning Commission as recommended by the City Engineer
(1) Additional right-of-way may be required by the Planning Commission to accommodate adjacent storm water runoff and drainage.
(2) Pavement width shall be measured from back of curb to back of curb.
(G) The minimum right-of-way of local streets, including marginal access streets and cul-de-sacs, shall be 50 feet. All cul-de-sacs shall terminate in a circular right-of-way with a minimum diameter of 110 feet; minimum pavement width shall be 86 feet on turnaround. No parking shall be permitted in a cul-de-sac terminus. The developer shall be required to place "No Parking" signs at the beginning radius, center and ending radius of the cul-de-sac with signs approved by the Ohio Manual of Uniform Traffic Control Devices.
(H) Where a street having two or more lots fronting thereon ends at a subdivision line for future extension, it shall be provided with a temporary paved turnaround until such extension is completed. The size of the turn-around shall not be less than 60 feet in diameter.
(I) Subdivisions that include, or border on, existing streets that do not conform to the required widths shall dedicate additional width along either or both sides of such street. The half width of all public rights-of-way abutting the proposed subdivision shall be brought to all applicable city improvement standards.
(J) All street intersections shall be a 90-degree angle of intersection unless special conditions warrant consideration and approval of other design.
(K) At all street intersections, the roadway turning radii shall be adequate to allow all motor vehicles, trucks, and emergency vehicles adequate room to turn into a development in a single movement.
(L) At street intersections the right-of-way line shall be rounded by an arc, the minimum radius of which shall be 20 feet. Street curb intersection shall be rounded by radii of at least 30 feet.
(M) Intersection of more than two streets at one point shall not be permitted.
(N) In the interest of public safety, and as a matter of policy, all points of ingress and egress shall be located as far as possible from the intersection of two or more major thoroughfares. Access control at major thoroughfares shall be taken into consideration in the design of the subdivision plat. The city or ODOT has the right to define access along major thoroughfares as shown in the Transportation Master Plan set forth in the Comprehensive Plan.
(O) Where parkways or special types of streets are involved, the Planning Commission may apply special standards to be followed in the design of such parkways or streets.
(P) Whenever the subdivision contains or is adjacent to a railroad right-of-way, or a highway designated as a limited access highway by the appropriate highway authorities, provision shall be made for either a marginal access street or a parallel street at a distance adequate to permit use of adjoining land.
(Q) Horizontal visibility on curved streets and vertical visibility on all streets shall be maintained along the centerlines as follows:
(1) Major highways and thoroughfares: 500 feet*.
(2) Collector streets and parkways: 300 feet*.
(3) Residential access streets: 100 feet*.
* Where topographic or other conditions warrant, the Planning Commission may, with the recommendation of the City Engineer, reduce these requirements.
(R) Horizontal curvature measured along the centerline shall have a minimum radius as follows:
(1) Major highways and thoroughfares: 500 feet*.
(2) Collector streets and parkways: 300 feet*.
(3) Residential access streets: 150 feet*.
* Where topographic or other conditions warrant, the Planning Commission may, with the recommendation of the City Engineer, reduce these radii requirements.
(S) All changes in grades shall be connected by vertical curves of sufficient radii to provide smooth transitions and required sight distances.
(T) Between reverse curves on major arterial streets there shall be a tangent of not less than 100 feet, and on collector and local streets such tangent shall be not less than 40 feet. For hillside areas between reverse curves on major arterial streets there shall be a tangent of not less than 50 feet, and on collector streets such tangents shall not be less than 20 feet.
(U) Maximum grades for streets shall not be greater than those shown below unless approved by the City Engineer and the Planning Commission.
TYPE OF STREET | MAXIMUM GRADE |
Major arterials | 4% |
Minor arterials | 7% |
Collector streets | 7% |
Local streets | 10% |
Pedestrian ways or crosswalks | 12% |
(V) The minimum grade of any street gutter shall not be less than 0.5%.
(W) New streets may be called avenue, circle, court, drive, place, street and way, but they shall not be called roads.
(X) Alleys shall not be permitted in residential areas but shall be included in commercial and industrial areas where needed for loading and unloading or access purposes where required; alley rights-of-way shall be at least 20 feet in width and shall be fully paved.
(Y) Dead-end alleys shall be avoided, but if unavoidable, shall be provided with adequate turnaround facilities at the dead-end, as determined by the Planning Commission.
(Z) The street approach to any proposed stub streets or cul-de-sac street shall not exceed more than 5% grade.
(AA) The use of cul-de-sac street designs shall be utilized only when physical features of the site warrant the use this design. Generally, a grid style street network is encouraged including the use of curvilinear design elements.
(BB) Each major subdivision shall provide for multiple access points to provide more efficient traffic flow, greater connectivity between adjacent developments and an adequate number of access points for fire, EMS and police personnel.
(CC) Medians shall not be located within any cul-de-sac street.
