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.
The subdivider or developer shall present on tracing cloth or paper, using India or equal quality ink, a plan and profile showing proposed street and road grades and drainage structures.
(a) Width of Pavement. 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 | Width of Pavement |
Major streets and highways | To conform to applicable cross-sections of the Official Highway Plan, as determined by the City Planning Commission and the City Engineer. |
Collector streets | 36 feet |
Local streets serving medium-high density development (eight families or more per net acre) | 36 feet |
Local streets serving medium density development (four to seven families per net acre) | 30 feet |
Local streets serving low density suburban development (three families or less per net acre) | 20 feet |
Alleys | 16 feet |
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 City 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.
(b) 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 sixteen feet. Sub-base construction shall be subject to the approval of the City Engineer.
(c) Residential Local and Collector Streets. These streets shall be constructed in accordance with subsection (c)(1) or (2) hereof, except in unusual circumstances which are based on the decision of the City Engineer as specified in subsection (c)(3) hereof.
(1) Portland cement concrete pavement having a minimum thickness of six inches, constructed on a properly prepared subgrade.
(2) Bituminous concrete pavement having a sub-base of "I-22" five inches thick and a base course of "B-19" four inches thick and a bituminous concrete wearing surface having a minimum thickness of two and one-half inches.
(3) The City Engineer has the authority to require higher standards where he deems unusual sub-base conditions made it necessary, or to permit lower standards where excellent natural sub-base conditions exist.
(d) Major Streets or Streets Servicing Commercial and Industrial Areas. These streets shall be constructed in accordance with subsection (d)(1) or (2) hereof, except in unusual circumstances which are based on the decision of the City Engineer as specified in subsection (d)(3) hereof.
(1) Portland cement concrete pavement having a minimum thickness of seven inches, constructed on a properly prepared subgrade.
(2) Bituminous concrete pavement having a sub-base of "I-22" six inches thick and a base course of "B-19" five inches thick and a wearing surface having a minimum thickness of two and one-half inches.
(3) The City Engineer has the authority to require higher standards where he deems unusual sub-base conditions make it necessary, or to permit lower standards where excellent natural sub-base conditions exist.
(e) Curbs and Gutters. The requirement of curbs or curbs and gutters will vary in accordance with the character of the area and the density of development involved. In urban or suburban areas curbs are necessary to control storm water runoff and to clearly define driving and parking areas.
(1) Curbs shall be required on all streets designed to serve areas where the existing or anticipated net residential density of the proposed subdivision equals or exceeds three families per net acre.
(2) In commercial developments, or where other similar intensive urban uses exist or are anticipated, curbs shall ordinarily be required. The installation of curbs may be required on major or minor highways if such construction is deemed necessary for public safety.
(3) Where curbs exist on abutting properties, their extension will ordinarily be required throughout the proposed subdivision.
(4) Where curbs are not required, adequate gutters shall be graded and protected by seeding or appropriate surfacing.
(5) Curbs may be of the 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 volume of "Construction and Material Specifications" of the Department of Transportation, State of Ohio, as they pertain to this type of improvement.
(f) Driveways. The maximum grade on driveways shall not exceed fifteen percent. Driveway pipe shall be reinforced concrete pipe or its equal with a minimum diameter of twelve inches and a minimum length of twenty feet. The subdivider or developer shall place approved drainage structures under intersecting roads, drives, lanes or property entrances and at other locations where required.
