(4) In general, service connections shall be provided for each proposed consumer at the time the water main is constructed. Service connections shall terminate seven feet within the right-of-way lines. Service lines shall have a minimum of four feet of cover.
(5) Plans for the construction of water mains, services and appurtenances shall be submitted to and approved by the Ohio Water Service Company and the Lake County Sanitary Engineer prior to submittal for approval by the Village.
(b) Sanitary Sewage and Sewerage. Each residential, commercial or industrial unit shall be serviced by an adequate sanitary sewage collection and disposal system. Individual household sewage disposal systems may be allowed, but only with the approval of the Lake County Board of Health.
(1) In general, all sanitary sewage collection and disposal systems shall be constructed in accordance with the rules, regulations and specifications of the Lake County Sanitary Engineer, the Lake County Board of Health and the Ohio Department of Health.
(2) Individual household sewage disposal systems shall be permitted and constructed by and in accordance with the rules, regulations and specifications of the Lake County Board of Health, except that the Village reserves the right to review and approve or disallow the installation of any such individual household system.
(3) All public sanitary sewers shall be eight inches in diameter or larger, constructed at such a gradient as to maintain a minimum velocity of flow of two feet per second or greater when flowing at fifty percent (50%) capacity using Kutter's "n" value of 0.013. All sewers shall be designed and installed so that at maximum rate of flow, the flow shall not exceed seventy percent (70%) of absolute theoretical capacity.
(4) After construction and cleaning, all main sewers including the manholes, laterals and house connections, shall undergo an infiltration or exfiltration test. The controlling water level shall not be less than three feet above the top of the pipe or the ground water table at the upper end of the section being tested. The maximum allowable rate of infiltration or exfiltration shall not exceed 400 gallons/inch diameter/mile of sewer/day.
(5) All service connections to public sanitary sewers shall be six inches in diameter or larger with a minimum slope of one-eighth inch per lineal foot of pipe, and shall extend from the main sewer to the limits of the dedicated right-of-way. The last two bell ends and the stopper for each connection shall be painted yellow for purposes of identification.
(6) Unless otherwise specifically authorized, the minimum depth of the invert of the sanitary sewer connection at the right-of-way line shall be six feet below the established center line grade of the pavement.
(7) In general, sanitary manholes shall be constructed at all changes in alignment and grade of the sewer, and at maximum intervals of 350 feet on sewers to twenty-four inches diameter and at maximum intervals of 450 feet on sewers over twenty-four inch diameter.
(8) Plans for the construction of sewage collection and disposal systems shall be submitted to and approved by the Lake County Sanitary Engineer, the Lake County Board of Health and the Ohio Department of Health, prior to submittal for approval by the Village.
(c) Storm Drains. An adequate storm drainage system shall be constructed for each subdivision. Where new streets are dedicated, the storm drainage system shall consist of a system of road and surface drainage or underground conduits which provide adequate runoff for all adjacent premises and for road drainage as shall be determined necessary by the Planning and Zoning Commission after consultation and in conformity with the recommendations of the Village Engineer.
(1) All public storm conduits shall be a minimum of twelve inches in diameter and constructed at such a gradient as to maintain a minimum velocity of flow of two feet per second or greater when flowing at fifty percent (50%) capacity.
(2) All service connections to public storm conduits shall be six inches in diameter or larger, and shall extend from the main conduit to the limits of the dedicated right-of-way. Downspouts from structures shall not be connected to the curb.
(3) Unless otherwise specifically authorized, the minimum depth of the invert of the storm service connection at the right-of-way line shall be six feet below the established center line grade of the pavement.
(4) When grate type inlets are used:
A. Slots shall run parallel to the direction of the flow;
B. Slots shall be at least twelve inches long; and
C. Areas of opening shall be at least fifty percent (50%) of the area of the grate.
(5) All areas which contribute or may contribute storm water, either in conduits or by overland flow, to the proposed storm drainage system shall be considered in the determination of the size of the proposed storm conduits or channels.
(6) The design and construction of all storm drainage systems shall be correlated with the Master Storm Drainage Plan of the Village.
(d) Pavements. All streets shall be improved with pavement having a width of not less than twenty feet, except minor streets having a length of less than 750 feet which do not presently or under the Village Comprehensive Plan will not connect with or provide access to or from more than one arterial, collector or marginal street, in which case the improved pavement shall be not less than eighteen feet in width, constructed in accordance with State of Ohio Department of Highway construction and material specifications in force at the time of construction.
(1) Minimum requirements shall be as set forth in the following schedules, the items referred to being those presently prescribed by the State of Ohio Department of Highway construction and material specifications:
Subgrade: | Item 203. |
Aggregate Base: | Minimum of eight inches; Item 304. |
Asphalt Intermediate Course: | Item 403. |
Asphaltic Concrete Surface: | Item 404; slope one-fourth inch per one foot from center to each side. |
Berm: | Each side minimum six feet width, except minor streets having a length of less than 750 feet which do not presently or under the Village Comprehensive Plan will not connect with or provide access to or from more than one arterial, collector or marginal access street, in which case the berm shall be not less than six feet on each side, of stabilized crushed stone; Item 411; slope one- half inch per foot. |
(2) At all intersections, the pavements shall be joined by a circular curve or "turnout" of a minimum radius of thirty-two and one-half feet, measured to the outside of the pavement. It is recommended that wherever feasible, the radius point of the pavement turnout be made coincident with that of the right-of-way.
(3) Pavement gradients shall not exceed seven percent (7%), with due allowance for reasonable vertical curves to insure a minimum sight distance of 500 feet.
(4) No pavement grade shall be less than four-tenths of one percent (0.40%) and changes of gradient of one percent (1%) or more shall be connected by a vertical curve.
(5) Approved monument boxes and monuments shall be installed at all points of intersection and change of alignment in the center lines of streets under the direction and responsibility of a Registered Surveyor.
(e) Grading. Each residential lot or parcel shall be so graded as to allow no ponding whatsoever of any surface water.
(1) Wherever feasible, grading shall be accomplished in such fashion that all surface water shall drain into inlets constructed within limits of the right-of- way.
(2) Where necessary, inlets and conduits draining into storm conduits shall be constructed in areas outside the limits of the right-of-way.
(3) The methods outlined in subsections (e)(1) and (2) hereof, are not to be construed as to prohibit any drainage, wherever feasible, into natural or constructed drainage channels.
(4) Particular attention shall be given all grading so as to avoid any ponding on or excessive runoff to contiguous property of any surface water, both during and subsequent to the period of construction.
(f) General Requirements.
(1) Unless specifically waived by the Village, all utilities and improvements constructed shall terminate only at the end of all streets proposed to be dedicated or on easements beyond such point, with the provision for necessary future extensions.
(2) Unless specifically waived by the Commission, all electrical and telephone lines shall be constructed and installed underground.
(3) Wherever feasible, all principal trenches for underground utilities shall be constructed outside of future paved roadways.
