1111.04 UTILITY AND STREET IMPROVEMENTS.
(a) Water Lines.
(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 it with such public water supply and provide a connection for each lot. All new streets shall be improved with six-inch water lines, provided, however, that the Planning Commission in its discretion may require larger lines within the subdivision where necessary or desirable. In such case, the excess cost of the larger lines shall be borne by the developer. Where larger line sizes are required for servicing areas outside the subdivision, the excess cost of the larger lines shall be borne by the City.
(2) Test wells. Where public water supply is not available, at least one test well shall be made in the area being platted for each 100 lots or each twenty-five acres of area, whichever is the smaller. In cases where copies of the logs of existing wells located within the area being platted are available, this may be submitted in lieu of making test wells. Test wells shall be at least twenty-five feet in depth and shall produce safe potable drinking water at a rate of not less than five gallons per minute per family.
A copy of the well log, which shall include the name and address of the well driller, shall be submitted with the plat to the Planning Commission.
(3) Location and construction of individual private wells. Individual private wells shall be located at least twenty-five feet from property lines; fifty feet from all septic tanks, approximately fifty feet from all tile disposal fields and other sewage disposal facilities; ten feet from all cast iron, vitrified or equivalent watertight pipe, as approved by the County Board of Health; and shall not be located within any flood plain unless the source is above the flood level and properly sealed.
As a precaution against seepage, an approved watertight seal shall be provided around the pump mounting.
All abandoned wells shall be sealed in a manner that will render them watertight as prescribed by the County Health Department.
In all cases where it has been determined that individual water supplies from private wells are not feasible, a public water distribution system will be required.
(4) 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. 3701.18 to 3701.21, inclusive.
(b) Sanitary Sewers.
(1) Sanitary sewers. 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 ten or more housing units must have a central sewerage system, approved by the Ohio Department of Health and accepted by Council. Where a public sanitary sewer is not reasonably accessible, the subdivider, the owner or the 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 City Engineer. Eight-inch sewer lines will normally be required, but the Planning Commission may, at its discretion, require larger lines where necessary or desirable. In such case, the excess cost of the larger lines shall be borne by the City.
(2) Individual sewage disposal facilities. In the event the installation of individual disposal systems shall be considered, the absorption ability of the soil, surface drainage and topography shall be the criteria for determining whether or not the installation of individual septic tank disposal systems is permissible. At least one percolation test shall be made for each lot area being platted, and each test shall be located in close proximity to the proposed sewage disposal unit. Each test shall be numbered and its location shown on the plat. Tests shall be made by an authority recognized by the County Health Department.
The general types of soil encountered in making the tests and the depth of ground water, if found, shall be documented and submitted with the plat together with the actual percolation time of each test hole and the name and address of the registered engineer or surveyor or other qualified persons acceptable to the County Health Department making the test and the dates on which they were made.
(3) Percolation tests. All percolation tests shall be performed in accordance with the requirements of the City Planning Commission and the County Board of Health.
The percolation test shall be made by the following method:
A. Dig or bore holes approximately six to ten inches wide, straight sides to a minimum depth of thirty inches or a maximum depth of forty-eight inches.
B. Keep filling holes with water until ground becomes soaked and allow all water to seep away. Then fill holes with water to a depth of twelve inches.
C. Record the time, in minutes, required for the last six inches of water to completely seep away. Divide the time by six to obtain the average time for water to fall one inch.
D. Determine the size of tile disposal field:
Lineal Feet of Tile Required | ||||
Average Time Required for Water to Fall One Inch as Shown by Percolation Test | Type of Leaching Soil | 2 or less Bedrooms | 3 to 4 Bedrooms | 5 to 6 Bedrooms |
Less than ten minutes | Good | 100 | 200 | 300 |
Ten to thirty minutes | Fair | 200 | 400 | 600 |
Thirty to sixty minutes | Poor | 300 | 600 | 900 |
Over sixty minutes | Leaching devices are not permitted. | |||
The general types of soil encountered in making the test and the depth of ground water, if found, shall be documented and submitted with the plat together with the actual percolation time of each test hole and the names and addresses of the registered surveyor and/or engineer making the test, as well as the dates on which they were made.
(4) Public sewer distribution systems. Group sewage disposal systems shall meet the requirements of the State Department of Health as prescribed by the laws of Ohio.
(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.
(1) Standards and specifications for drainage facilities. The construction of storm water drainage improvements shall be subject to the approval of the City 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 such storm sewer systems are not accessible, adequate storm water drainage shall be provided by natural drainage channels with easements of adequate width as approved by the City 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 least 0.20 of a foot grade per 100 feet, or otherwise approved.
B. If the permitted roadway ditch is in excess of two percent, an approved type 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 City Engineer. The minimum diameter of a culvert pipe shall be twelve inches. Head walls, 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 scaled joints having a diameter of not less than twelve inches. When special drainage designs are necessary, such as masonry or concrete structures, etc., such designs in detail must be submitted to the City Engineer and Conservancy District for approval in advance of the completion of the construction plans. The driveway culverts shall be laid so as to maintain the flow line of the ditch or gutter. Head walls 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 curb is used. (Ord. 45-67. Passed 8-7-67.)
(4) Subsurface water drains. Drain lines for conveying subsurface water shall be installed in all subdivisions that are constructed on moderate or poorly drained soils (clay, silt, shale, etc.) as defined by the United States Soil Conservation Report for Tuscarawas County. Where subdivisions are constructed on well drained soils (sand and gravel) as defined by the same soils report, drain lines for conveying subsurface water will not be required. Also, wherever subdivisions have creeks in them to which subsurface water can be directly discharged, drain lines will not be required.
A. The subject drain lines shall be polyvinyl chloride plastic pipe with o-ring joints conforming to the latest requirements of A.S.T.M. D 3034 and A.S.T.M. D 3212 and have a minimum Standard Dimension Ration (SDR) of 35. The minimum size of the drain lines shall be six inches in diameter and shall be large enough to convey all of the subsurface waters which they are receiving. The pipe shall be installed in an encasement of pea gravel which shall extend a minimum of four inches below the pipe and above the pipe. The pipe lines shall be installed on each side of the street, where such is required, between the curbs and sidewalks at a distance of two feet from the back of the curbs.
B. Subsurface waters from springs, seep holes and basement sump pumps shall be piped into the subject lines from each source or home from which it emanates. The drain lines themselves shall be connected into the street storm sewer catch basins wherever they occur.
C. In the case where creeks are located adjacent to lot boundaries, springs, seep holes and basement sump pumps shall be piped directly into the creeks.
D. It is the intent of this subsection (4) to convey all subsurface waters in a subdivision via pipe lines to the storm drainage system for the subdivision, and to prohibit the discharge of any subsurface waters to flow openly into the streets of the subdivision.
(Ord. 37-94. Passed 5-2-94.)
(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 Subdivision Regulations, except that the street improvements for areas remotely situated with respect to City services may conform to the standards specified in the Subdivision Regulations of Tuscarawas County.
(1) 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 Streets | Right of Way | Width of Pavement |
Urban: | ||
Major streets and highways | eighty feet or over | Variable* |
Secondary and collector streets | seventy feet | thirty-eight feet |
Local streets serving medium- (six families per net acre or more) density suburban development | sixty feet | thirty-six feet |
Local streets serving low-density suburban development | fifty feet | thirty feet |
Alleys | twenty feet | sixteen feet |
Rural areas remotely situated with respect to City sewers: | ||
Secondary rural roads | seventy feet | twenty-two feet |
Local rural roads | sixty feet | twenty feet |
*To conform to the applicable standards of the Major Highway Plan, as determined by the City Planning Commission and the City Engineer.
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, provisions 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 simultaneously with the subdivider's improvement program.
(2) Subgrade. The subgrade shall be free of sod, vegetation 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.
(Ord. 45-67. Passed 8-7-67.)
(3) Pipe underdrains. Pipe underdrains shall be placed on each side of the street 1'-0" behind the curbs and at a depth which will provide 1'6" of aggregate cover over the top of the pipe. The trench excavated for the underdrains shall be excavated to provide a 1'0" wide opening to a depth which will provide 4" of aggregate under the pipe. The trench shall be completely filled with No. 57 size gravel. The aggregate shall extend to the top of the gutters of the curbs and over to the back of the curbs and the edge of the street base course. Underdrain pipe shall be either perforated concrete pipe, perforated vitrified clay pipe or perforated polyvinyl chloride plastic pipe. The underdrain pipe shall be connected into the storm water drainage system for the streets. Pipe underdrains shall be perforated P.V.C. pipe with a minimum of four (4) rows of perforations. The pipe and fittings shall conform to ASTM F758, Type PS46 and as applicable, to Item 605 of the latest edition of the State of Ohio Department of Transportation Construction and Materials Specifications.
(Ord. 60-08. Passed 1-5-09.)
(Ord. 60-08. Passed 1-5-09.)
A. Pipe underdrains for streets shall be installed where streets are constructed on top of moderate and poorly drained soils (clay, silt, shale, etc.) as defined by the United States Soil Conservation Report for Tuscarawas County. Where streets are constructed on top of well drained soils (sand and gravel) as defined by the same soils report, pipe underdrains will not be required.
(4) Base course. A compaction test on road sub base shall be required prior to acceptance by the City for installation of a new asphalt base. The base course for streets shall consist of a four inch layer of asphaltic concrete placed on top of the limestone. Both layers shall be individually compacted in place with a vibratory roller. Unless otherwise stated herein, the limestone aggregate shall conform to item 304 of the latest edition of the State of Ohio Department of Transportation Construction and Material Specifications, and the asphaltic concrete shall conform to item 301 of the latest edition of the State of Ohio Department of Transportation Construction and Material Specifications.
A. Depending upon the soil conditions and the type of traffic which the street is expected to receive, the City may require, in its discretion, greater thickness for the base courses.
B. Streets constructed over moderately or poorly drained soils (including, but not limited to clay, silt, or shale), as said term is defined by the United States Soil Conservation Report for Tuscarawas County, shall require a four inch thick layer of limestone aggregate base course. Streets constructed over well drained soils (including but not limited to sand and gravel), as said term is defined by the United States Soil Conservation Report for Tuscarawas County, shall not require a limestone aggregate base course.
C. In those circumstances wherein a limestone aggregate base course is required, said base course shall extend to the underside of the concrete gutters, having a minimum thickness there under of four inches.
(5) Surface course. The surface course for streets shall consist of a three inch thick layer of asphaltic concrete applied in layers of 1 3/4 inch and 1 1/4 inch layers, compacted in place with a vibratory roller. Unless otherwise noted herein, the asphaltic concrete surface course shall conform to item 404 of the latest edition of the State of Ohio Department of Transportation Construction and Material Specifications.
A. Such asphaltic concrete surface shall not be constructed until all ditches have settled and the street surface is approved by the City, but not later than eighteen months following the installation of water mains, sewer mains, lateral sewers and service lines.
B. The right is reserved to the City 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 City for the completion of the required improvements as provided in subsection (j) hereof. The subdivider shall give three days’ notice to the City as to the time when the construction of the base and surface courses is to be started so that the work may be inspected by the City or its duly authorized agents. After the final rolling, the street or road shall be closed to traffic for twenty-four hours. (Ord. 26-02. Passed 5-20-02.)
(6) Concrete pavement. If the subdivider elects to construct concrete pavement or if such type pavement is required by the City in order to meet traffic needs, such concrete pavement shall have a minimum thickness of eight inches and shall meet Item 451, Reinforced Portland Cement Concrete Pavement, of the latest edition of the State of Ohio Department of Transportation Construction and Material Specifications.
(7) Curbs and gutters. Concrete curbs and gutters are required on all new streets; except, the City may choose to delete such on streets serving industrial parks or similar uses. Where curbs are not required, adequate drainage ditches shall be graded and protected by seeding or appropriate surfacing. Curbs and gutters shall conform to the applicable parts of Chapter 902 of these Codified Ordinances.
(8) Driveways. The maximum grade on driveways shall not exceed ten percent (10%). Driveway pipe shall be concrete pipe with a minimum diameter of twelve inches and a minimum length of twenty feet, or larger as required by the drainage condition and the City. The subdivider or developer shall place approved drainage structures under intersecting roads, drives, lanes or property entrances and at other locations, where required. (Ord. 37-94. Passed 5-2-94.)
(e) Utilities and Other Improvements. Electrical service, gas mains and other utilities should 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. (Ord. 5-85. Passed 2-18-85.)
(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. However, the Planning Commission together with Council pursuant to subsection (f)(l) herein may waive this requirement and allow sidewalks along only one side of any new street where it determines that sidewalks on both sides of such new street are not necessary. Council may reject a plat where sidewalks have been waived pursuant to this provision unless Council by resolution has given authorization to the Planning Commission for the waiver as set forth above. Beyond the corporation limits, in areas where the predominant lot width is 100 feet or more, the Planning Commission, at its discretion and without consultation with Council may waive the requirement for any sidewalks.
(1) When the Planning Commission receives a preapplication sketch requesting a waiver for sidewalks in a subdivision in the City pursuant to the above paragraph, the Commission shall immediately notify Council together with its recommendation and Council shall then consider the waiver request. In the event that Council, by resolution, approves the waiver request and finds that such waiver would not substantially detract from the purpose and intent of the Dover City Planning Code, then the Planning Commission may proceed with the preliminary application as set forth in the preceding paragraph. If, however, Council shall reject the proposed waiver, then the Planning Commission shall not grant the waiver requested for the subdivision, but shall then proceed to consider the preliminary plat for all other purposes as set forth above.
(2) No waiver of sidewalk requirements as set forth in this subsection (f) shall be granted except by the above procedure and except as included on the preliminary plat submitted pursuant to Section 1107.02.
(Ord. 74-89. Passed 10-16-89.)
(3) Sidewalks shall be installed on a lot within one year after a building permit has been issued, or two years after the subdivision developer has sold or transferred a lot if no building permit has been issued. If a lot has not been sold or transferred within a two-year period by the developer, or the sidewalk has not been installed within one year of the issuance of the building permit, the Building and Zoning Codes Administrator may grant a sidewalk completion time waiver, if requested in writing by the developer, and if the health, safety and welfare of the citizens of Dover will not be adversely impacted. The waiver may be granted in twelve-month increments.
(Ord. 60-08. Passed 1-5-09.)
(Ord. 60-08. Passed 1-5-09.)
(g) Street Name Signs. Street name signs of a type similar to those in use throughout the City, shall be erected by the City at all intersections.
(h) Street Lighting. Plans for street lights, if any, shall be submitted to the City Engineer for approval.
(i) Trench Backfilling. All trenches for water lines, sewers, utilities, etc., 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 curb is used.
(1) The improvements listed in the sections of these Subdivision Regulations have been satisfactorily completed prior to such approval; or
(2) The subdivider shall file with the Director of Public Service a surety bond, cashier's or certified check for the estimated amount of construction cost which shall be approved by the City Engineer, guaranteeing to the City that such improvements will be constructed and completed in a satisfactory manner and within a period specified by the City Engineer, but such period shall not exceed one year beyond completion. Such bond or checks shall be approved by the City Solicitor and shall be made payable to and enforceable by the City.
Upon satisfactory completion of the improvements and approval of the same in writing by the City 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 City 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 City 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 City Planning Commission for the proper and continuous maintenance and supervision of such facilities by the lot owners in the subdivisions. (Ord. 45-67. Passed 8-7-67.)
(l) Any new street developed by a private developer and dedicated to the City shall have a street tree plan approved by the Shade Tree Commission. As an alternative, the developer may permit the Shade Tree Commission to develop the street tree plan with the cost of all trees to be paid by the developer. In either case, the improvements bond required in subsection (j) hereof shall include an amount sufficient to cover the cost of compliance with such plan as estimated by the Shade Tree Commission. (Ord. 5-85. Passed 2-18-85.)
