(a) Water Supply.
(1) Public water supply. Where public water supply is available as determined by the Planning Commission, the subdivider or developer shall construct a system of water mains and connect with such public water supply and provide a connection for each lot. Any area or subdivision of twenty or more single-family housing units must have a central water system and central sewerage system, approved by the State Department of Health and the Municipality.
Six-inch water lines will normally be required, but the Planning Commission may, at its discretion, require larger lines where necessary or desirable, in which case, the excess cost of the larger lines shall be borne by the Municipality.
(2) Public water distribution systems. Public wells and other public water distribution systems shall meet the requirements of the State Department of Health as cited in Ohio R.C. 3701.21.
(b) Sanitary Sewers.
(1) Public sewer extensions. If a subdivision can be reasonably served by the extension of an existing public sanitary sewer, as determined by the Commission, the subdivider or developer shall provide a system of sanitary sewer mains and shall provide lateral connections for each lot. Any area or subdivision of twenty or more housing units must have a central sewerage system, approved by the State Department of Health and accepted by Council. Where a public sanitary sewer is not reasonably accessible, the subdivider, owner or developer may provide a package plant for the group, or septic tanks for each lot, provided that such package plants or septic tanks are installed in accordance with State and County or local Board of Health requirements. Whenever main lines are installed, sewer and water shall be extended to property lines. Connections to public sanitary sewer lines shall be subject to the approval of and according to the specifications of the Municipal Engineer and the Municipal Utility Department.
Eight-inch sewer lines will normally be required, but the Planning Commission may, at its discretion, require larger lines where necessary or desirable, in which case, the excess cost of the larger lines shall be borne by the Municipality.
(2) Percolation tests. All percolation tests shall be performed in accordance with the requirements of the Planning Commission and the County Board of Health.
(3) Public sewer distribution systems. Group sewage disposal systems shall meet the requirements of the State Department of Health as prescribed by the laws of the State.
(c) Drainage. All necessary facilities, including underground pipe, inlets, catch basins or open drainage ditches shall be installed to provide for the adequate disposal of subsurface and surface water and maintenance of natural drainage courses. All storm drainage facilities within the subdivision shall connect to an adequate drainage outlet. A drainage plan shall be submitted simultaneously with the plat of any subdivision, showing the proposed scheme of surface drainage. Storm drainage shall be separate from the sanitary sewer system.
(1) Standards and specifications for drainage facilities. The construction of storm water drainage improvements shall be subject to the approval of the Municipal Engineer.
(2) Storm sewers and storm water. A drainage system adequate to serve the needs of the proposed new streets and the entire subdivision will be required in the new subdivisions. Where an adequate public storm sewer main is available at the plat boundary, the subdivider shall construct a storm sewer system and connect with such storm sewer main. If the storm sewer systems are not accessible, adequate storm drainage shall be provided by natural drainage channels with easements of adequate width as approved by the Municipal Engineer.
(3) Culverts and bridges. When natural drainage channels intersect any street right of way, it shall be the responsibility of the subdivider to have satisfactory bridges and culverts designed and constructed. Where culverts are required, the following minimum requirements shall be observed:
A. Where drainage ditches are permitted, they must have at leat 0.20 of a foot grade per hundred feet, or otherwise approved.
B. If the permitted roadway ditch is in excess of two percent (2%) an approved gutter using concrete, stone, sod or underground drainage must be used, with sufficient inlets spaced so as to keep the volume of water at a low level. All culverts shall extend across the entire right-of-way width of the proposed road. The cover over the culvert and its capacity shall be approved by the Municipal Engineer. The minimum diameter of a culvert pipe shall be twelve inches. Headwalls, depending on existing drainage conditions, may be required.
C. Driveway culverts shall have a minimum length of twenty feet. Driveway culverts shall be double strength vitrified pipe or equal, with a sealed joint having a diameter of not less than twelve inches. When special drainage designs are necessary, such as masonry or concrete structures, such designs in detail must be submitted to the Municipal Engineer for approval in advance of the completion of the contruction plans. The driveway culverts shall be laid so as to maintain the flow line of the ditch or gutter. Headwalls may be required.
D. All trenches for water lines, sewers, utilities, etc., within the pavement or driveway areas shall be backfilled with grit to a point within a minimum of six inches of the subgrade and to a point three feet outside the pavement edge or three feet back of the curb, if a curb is used.
(d) Street Improvements. 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, except that the street improvements for areas remotely situated with respect to Municipal services may conform to the standards specified in the Subdivision Regulations of Tuscarawas County.
(1) Width of pavement. The width of the pavement will vary depending upon the character of the development served and the amount of traffic expected to utilize the street.
A. The following are the minimum street pavement widths:
Type of Streets | Right of way (Feet) | Width of Pavement (Feet) |
Urban: | ||
Major streets and highways | Variable* | Variable* |
Secondary and collector | 70 | 38 |
Local streets serving medium density (8 families per net acre or more) suburban development | 60 | 36 |
Local streets serving low- density suburban development | 50 | 30 |
Alleys | 20 | 16 |
Rural areas remotely situated with respect to Municipal sewers: | ||
Secondary rural roas | 70 | 22 |
Local rural roads | 60 | 20 |
* To conform to applicable standards of the Major Highway Plan, as determined by the Municipal Planning Commission and Municipal Engineer.
B. 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 Municipal Engineer may be required in addition to the necessary number of lanes for moving traffic. Where pavement widths greater than those specified herein are necessary, provision of the 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 simultaneosly with the subdivider's improvement program.
(2) 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. Subbase grade tolerance shall be not more than one inch in sixteen feet. Subbase construction shall be subject to the approval of the Municipal Engineer.
(3) Base course. Base course shall consist of one layer of bankrun gravel three inches thick and a final layer of D-6 aggregate two inches thick, each thoroughly compacted and graded with a crown of approximately one quarter of an inch per footbase. A greater thickness may be required depending upon the type of subsoil and subsurface drainage conditions and other pertinent factors. All materials and construction procedures shall be subject to approval by the Municipal Engineer.
(4) Surface course. Upon the expiration of the established maintenance period for the base course, the surface course shall be constructed in accordance with the appropriate standards as determined by the Municipal Engineer. The minimum surface course shall consist of the following:
A. A primer or tack coat of bituminous oil, of 0.60 gallons per square yard. That prime shall be allowed to cure for at least five days before applications of a double seal coat of 0.30 gallons of MC-4, MC-5, RS-2 or another approved bituminous seal. Each application shall be covered with thirty pounds of #6 crushed limestone or its equal for each course per square yard.
B. The right is reserved for the Municipal Engineer to determine the proper type and time for the application of the surface course, but in no event will the subdivider be required to defer the construction of the surface course for a period in excess of that specified by the Municipal Engineer for the completion of the required improvements as provided in subsection (j) hereof.
The subdivider shall give three days' notice to the Municipal Engineer as to the time when the construction of the base and surface courses is to be started so that work may be inspected by the Muncipal Engineer or his duly authorized agents. After the final rolling, the street or road shall be closed to traffic for twenty-four hours.
(5) Concrete pavement. If the subdivider elects to construct concrete pavement or if such type of pavement is required by the Municipality in order to meet traffic needs, such concrete pavement shall have a minimum thickness of six inches and shall meet the current T-70 Portland Cement Concrete Pavement Specifications of the State Department of Highways.
(6) Curbs and gutters.
A. The requirements of 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.
B. Curbs shall be required on all streets designed to serve areas where the existing or anticipated net residential density of the area surrounding the proposed subdivision equals or exceeds three families per net acre.
C. Where residential lot frontages are less than eighty-five feet 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.
D. Where curbs exist on abutting properties, their extension will ordinarily be required throughout the proposed subdivison.
E. When curbs are not required, adequate gutters shall be graded and protected by seeding or appropriate surfacing.

Curbs, combined curbs, gutters and graded gutters shall be constructed in conformance with the current construction and material specifications of the State Department of Highways as they pertain to this type of improvement.
(7) Driveways.
A. The maximum grade on driveways shall not exceed ten percent (10%). Driveway pipe shall be concrete pipe except that, other than for the gutter, it may be extra-vitrified pipe or equal, with a minimum diameter of twelve inches and a minimum length of twenty feet.
B. The subdivider or developer shall place approved drainage structures under intersecting roads, drives, lanes or property entrances and at other locations where required.
(e) Utilities and Other Improvements. Electrical service, gas mains and other utilities shall be provided within each subdivision. Whenever such facilities are reasonably accessible and available, they may be required to be installed within the area as required. Trees may be planted along the streets outside the right of way.
(f) Sidewalks. Concrete sidewalks having a minimum width of four feet and having a minimum thickness of four inches shall be installed on both sides of all new streets, provided, however, that the Planning Commission may waive this requirement and allow sidewalks along only one side of any new street where in its sole and absolute discretion it determines that sidewalks on both sides of such new street are not necessary.
(g) Street Name Signs. Street name signs, of a type similar to those in use throughout the Municipality, shall be erected by the Municipality at all intersections.
(h) Street Lighting. Plans for street lights, if any, shall be submitted to the Municipal Engineer for approval.
(i) Trench Backfilling. All trenches for water lines, sewers and utilities within the pavement or driveway areas shall be backfilled with granular material to a point within a minimum of six inches of the subgrade and to a point three feet outside the pavement edge or three feet back of the curb, if a curb is used.
(j) Improvements Bond. The improvements and standards therefor described in Section 1117.03 and this section have been adopted by Council, and no final subdivision shall be approved unless the improvements listed in the sections of these Regulations have been satisfactorily completed prior to such approval or the subdivider shall file with the Service Director a surety bond, cashier's or certified check for the estimated amount of the construction cost which shall be approved by the Municipal Engineer and Utility Department, guaranteeing to the Municipality that such improvements will be constructed and completed in a satisfactory manner and within a period specified by the Municipal Engineer. Such period shall not exceed one year beyond completion. The bond or checks shall be approved by the Law Director and shall be made payable to and enforceable by the Municipality. Upon satisfactory completion of the improvements and approval of the same in writing by the Municipal Engineer, and with the presentation of letters of certification of payment in full of all contractors, subcontractors, suppliers of materials, engineers, surveyors and all inspection fees or other fees incurred by the installation of the improvements by the subdivider, the bonds may be released in writing by the Clerk of the Municipality or the cashier's or certified check may be returned to the developer.
(k) Provisions for Maintenance and Operation. Where the subdivision contains sewers, sewage treatment plants, water supply systems, park areas, street trees or other physical facilities necessary or desirable for the welfare of the area and which are of common use or benefit and which are of such character that the Municipality or other public agency does not desire to maintain them, provisions shall be made by trust agreements, which are a part of the deed restrictions and which are acceptable to the Planning Commission, for the proper and continuous maintenance and supervision of such facilities by the lot owners in the subdivision.
