The regulations within this section shall control the manner in which streets, lots and other elements of a subdivision are arranged on the land. These design controls shall help insure convenient and safe streets, creation of usable lots, provisions of space for public utilities and restriction of land for public use, such as park land, open space, historical and archaeological purposes. The planning of attractive and functional neighborhoods, shall be promoted, minimizing the undesirable features of unplanned growth patterns. The Commission may approve an innovative design concept in subdivision planning or engineering design following evaluation of a proposed plan.
(a) Comprehensive Development. When a Comprehensive Development Plan has been adopted by the Commission, then such plan will be used in reviewing and evaluating proposed subdivisions of land within Mahoning County under the Commission's jurisdiction.
(b) Suitability of Land. If the Commission determines that land proposed to be subdivided is unsuitable for subdivision development due to flooding, poor drainage, topography, soil, inadequate supply of water, heating fuels or other required utilities, transportation facilities, abandoned mines, high pressure and/or combustible transmission lines, gas and/or oil facilities which create a poor safety situation and other such conditions which may endanger health, life or property; and if from investigations conducted by the agencies or companies concerned it is determined that the land should not be developed for the purposes proposed in the best interest of the public, the Commission may disapprove the land for subdivision until adequate methods are furnished by the applicant for solving the problems that will be created by the development of the land.
(c) Lot Design.
(1) Dimensions.
Minimum lot dimensions shall be as follows:
Sanitary Sewer | Width | Depth | Area |
Not Available | 100' | 200' | 1.2 Acre |
Available | 60' | 140' | 9,000 sq. ft. |
(2) Minimum frontage on cul-de-sac.
Sanitary Sewer Available | 35' |
Not Available | 50' |
(3) Type of street based on minimum lot widths.
Type A Street | 100' or less |
Type B Street | Over 100' |
NOTE: The Commission approves the type of street construction which is suitable to the area being subdivided.
(4) Board of Health approval. The County Board of Health shall approve all lots where sanitary sewers are not available, and may require additional lot frontage and/or area for proper installation of an individual sewerage system. It is recommended that the owner or legal representative contact the Planning Office in order to find out if additional frontage and/or lot area is required before a final plat is prepared.
(d) Township Standards. In zoned townships, the lot dimensions and building setback lines shall conform to the Zoning Ordinance where the standards are higher than required by these regulations.
(e) Incorporated Area Under a Planning Assistance Contract. The Commission and the officials of an incorporated unit of government shall jointly administrate these Subdivision Regulations in the incorporated area, where a lawfully adopted contract of joint cooperation has been signed by both parties and lawfully recorded in the office of the Mahoning County Recorder.
(f) Determination of Lot Width. The lot width shall be measured at the minimum building setback line.
(g) Building Setback Line. The minimum building setbacks shall be as follows:
RESIDENTIAL | COMMERCIAL AND INDUSTRIAL |
40 Feet | 35 Feet |
(1) All setbacks shall be measured from the front property line (street right-of-way line).
(2) Where a proposed widening of an existing right-of-way is planned according to the Mahoning County Major Thoroughfare Plan, then the building setback line shall be established based on the proposed right-of-way width and not the existing.
(3) Where there are already dwellings constructed and on line within a zoned township, then the subdivider must conform to the setback requirement or method established in the valid township ordinance at the time of platting. Where there is no zoning, the Commission's decision is final.
(h) Lot Lines.
(1) All side and rear lot lines shall be straight. Side lot lines shall be substantially at right angles or radial to street lines. The lot arrangement and design shall be such that all lots will provide satisfactory building sites properly related to topography and the character of surrounding development.
(2) Rear lot lines shall have a minimum length of fifteen feet to eliminate pointed lots in order to insure proper maintenance of the lot and avoid encroachment onto adjacent property.
(3) The width to depth ratio shall not exceed one to five.
(i) Street Frontage. All lots shall abut by their full frontage on a dedicated street.
(j) Corner Lots. Corner lots shall have a minimum width of seventy-five feet and a minimum residential side building setback line of twenty feet as measured from the side street right-of-way or property line.
(k) Lots to be Avoided.
(1) Double frontage lots shall be avoided except where necessary because of topography, and in areas used for business and industry.
(2) Butt lots shall be avoided except where they are necessary to meet existing conditions.
(3) Lots with extreme angle points and unusual shapes shall be avoided.
