(a) Street Improvements. All streets shall be graded to their full width, including side slopes, and improved in conformance with the standards given or referred to in these regulations.
(b) Street Subgrade. The subgrade shall be free of sod, vegetative or organic matter, soft clay, and other objectionable materials for a depth of at least two feet below the finished surface. The subgrade shall be properly rolled, shaped, and compacted and shall be subject to the approval of the Mahoning County Engineer.
(c) Pavement Design. The developer has the option of using any of the pavement design provided in Part Four of these regulations (Typical Sections - Design Standards). The Planning Commission may require pavement of greater width and thickness upon recommendation of the County Engineer, based on his evaluation of subgrade, traffic and wheel load conditions. There are no typical section pavement examples for a commercial or industrial street. The designs will vary depending upon the use intended.
(d) Grading. Streets shall be graded to the full width of the right of way with side slopes not steeper than a ratio of four feet horizontally to one foot vertically.
(e) Guard Rails. Guard rails shall be installed by the subdivider where required by the County Engineer.
(f) Upright Curbs and Curbs and Gutters. Curbs or combination curb and gutters shall be required on all type "A" streets (See Typical Sections, Part Four for specifications). Where curbs exist on abutting properties, their extension shall be required by the subdivider throughout the new subdivision.
(g) Curb Cuts.
(1) Drop curb shall be provided for driveways during the initial construction or by saw cutting after the curb is placed. If roof drain outlets into the curb are approved by the Commission, then an opening of sufficient diameter shall be provided. Saw cutting shall be used at all times to avoid curb damage and to avoid unsightly construction procedures and shall be on an angle.
(2) Drop curbs shall be constructed at all intersections for the handicapped and at other areas where the Commission deems it necessary to assist the handicapped person.
(h) Sidewalks.
(1) Sidewalks shall be provided where considered desirable by the Commission for protection of the public, such as in the vicinity of schools, churches, public open space areas and commercial development. A modified sidewalk system could possibly be required in a planned industrial park complex.
(2) A. Normally the sidewalk location shall be parallel to and one foot within the right-of-way line, but the Commission may consider approval of an innovative sidewalk design pattern involving a complete, overall master plan for a parcel of real estate.
B. Some of the points the Commission will be evaluating in regards to an innovative sidewalk design would be the ultimate connection points, topography, proximity to planned structures, privacy to dwelling occupants and safety of the persons using the walkway system, especially at night.
(i) Driveway Grade. Driveways shall have a maximum grade of eight percent (8%). See Section 1109.04
(c) for additional driveway requirements.
(j) Street Signs.
(1) Street name signs of a type throughout the County shall be provided and erected by the subdivider at all intersections immediately upon the written request of the Commission.
(2) In order to achieve uniformity in street sign design and construction within a specific township, it is recommended that the developer contact the township road supervisor.
Note: No street will be accepted for public use until the proper street signs are installed.
(k) Trees.
(1) Existing trees shall be retained in new subdivisions wherever possible and new plantings shall be furnished by the subdivider in areas as requested by the Commission. Plantings at street shall be so located as to maintain adequate sight distance. An improvement guarantee may be requested by the Commission.
(2) The voluntary assistance of a State Urban Forester is available upon the request of the Commission.
