All streets and thoroughfares shall be graded to their full width, including side slopes, and improved in accordance with the standards outlined or referred to in these regulations. Plans and specifications for street improvements shall be subject to approval by the Engineer.
(A) Subgrade. The subgrade shall be free of sod, vegetation matter or other similar material. Where poor subsurface drainage conditions exist, adequate drainage shall be installed. The subgrade shall be rolled with a roller of not less than seven tons in weight. Sub-base grade tolerance shall be not more than one inch in 16 feet. Sub-base construction shall be subject to the approval of the Engineer.
(B) Width of pavement.
(1) The width of pavement will vary, depending upon the character of the development served and the amount of traffic expected to utilize the street. The following are the minimum street pavement widths:
Type of Street | Minimum Pavement Width |
Major streets and highways | *Variable (See Major Thoroughfare Plan) |
Secondary or collector streets | 36' - 44' |
Minor or local urban streets | 27' - 36' |
Rural roads and streets serving low-density suburban development | 24' - 27' |
Service streets | 16' |
* To conform to applicable cross-sections of Major Thoroughfare Plan, as determined by the Commission and the Engineer. | |
(2) In certain instances, especially where a commercial area is involved and no off-street parking facilities are provided and no parking is permitted on the street at any time, a parking lane at least eight feet wide on each side of the street and paved to the satisfaction of and in accordance with the specifications approved by the Engineer may be required in addition to the necessary number of lanes for moving traffic. Where pavement widths greater than those specified above are necessary, provision of same shall be discussed with the public officials having jurisdiction over the planning and construction of public ways to determine whether or not public expenditures for such additional width can or should be made simultaneously with the subdivider's improvement program.
(C) Base course. The base course shall be the type known as B119, as set forth by the current Construction and Material Specifications of the Department of Highways, State of Ohio. Thickness of base course after rolling shall not be less than the following:
Type of Street | Minimum Thickness of Base Course |
Major streets and highways | *Variable |
Secondary or collector street | 8 in. |
Minor or local urban streets | 6 in. |
All other streets and highways | 6 in. |
* To be determined by the authority having jurisdiction. A primer cost with chipping shall be required prior to surfacing. | |
(D) Surface course - asphaltic concrete. Upon the expiration of the established maintenance period for the base course, the surface course shall be constructed in accordance with the specifications for T-35* asphaltic concrete as set forth by the current Construction and Material Specifications of the Department of Highways, State of Ohio. The thickness of the surface course after rolling shall not be less than the following:
Type of Street | **Minimum Thickness of Surface Course |
Type of Street | **Minimum Thickness of Surface Course |
Major streets and highways | *** Variable |
Secondary or collector street | 2-1/2 in. |
Minor or local urban streets | 2 in. |
Streets serving low density suburban development | 2 in. |
Alleys | 2 in. |
* T-35 is required for streets with curb and gutters. | |
T-34 may be used on streets where ditches are used, provided the minimum thickness of the surface course is increased by 1/2 in. from the above specifications. | |
** For intersections and parking strips on minor or local streets, use secondary or collector street specifications.
| |
*** To be determined by the authority having jurisdiction. | |
(E) Concrete pavement. If the subdivider elects to construct a concrete pavement, or if such type of pavement is required by the municipality in order to meet traffic needs, such concrete pavement shall meet the current Construction and Material Specifications manual requirements, Department of Highways, State of Ohio, for T-70 Portland Cement Concrete Pavement. The preparation of the subgrade and the insulation course as may be required shall meet the approval of the responsible governmental officer. The thickness specifications are as follows:
Type of Street | Design Thickness |
Major street or highway | *Variable |
Secondary or collector street | 8 in - 5-1/2 in. - 8 in. |
Minor or local urban street | 7-1/2 in - 5 in. - 7 in. |
Streets serving low density suburban development | 7-1/2 in. - 5 in. - 7-1/2 in. |
Service streets | 7-1/2 in. - 5 in. - 7-1/2 in. |
* To be determined by the authority having jurisdiction. | |
All intersections shall be of uniform design using edge thickness.
(F) Curbs and gutters.
(1) Curbs shall be required on all streets designed to serve areas where the existing or anticipated residential density of the area surrounding the proposed subdivision equals or exceeds three families per acre, exclusive of streets and public properties.
(2) In commercial developments or where other similar intensive urban uses exist or are anticipated, curbs shall be required. The installation of curbs may be required on major, secondary, and minor highways if such construction is deemed necessary for public safety.
(3) Where curbs exist on abutting properties, their extension will be required throughout the proposed subdivision.
(4) Curbs shall not be constructed where pavements are less than 24 feet in width. Where curbs are not required, adequate gutters shall be graded and protected by seeding or appropriate surfacing.
(5) Curbs may be of a wall type or may be combined with gutters built of concrete. Curbs, combined curbs and gutters, and graded gutters shall be constructed in conformance with the current Construction and Material Specifications of the Department of Highways, State of Ohio, as they pertain to this type of improvement.
