Design standards - see P. & Z. Ch. 1113
Within the corporate limits, all plats and subdivisions of land within the Village shall conform to the rules and regulations contained herein as adopted by Council and/or the Planning Commission, and the subdivider shall provide, construct, install, and pay for the minimum improvements required by the Village and specified herein. All detailed design plans for the proposed improvements shall be prepared by a Professional Engineer registered in the State of
Ohio. (Ord. 574. Passed 5-21-97.)
Plans and profiles and cross-sections shall be prepared at a horizontal scale of not less than one (1) inch equals 50 feet and a vertical scale of not less than one (1) inch equals five (5) feet for all proposed streets and sewers, with typical cross-sections indicating proposed crowns and slopes and shall be included in the detailed design plans for the proposed improvements.
(Ord. 574. Passed 5-21-97.)
All lots shall be graded to carry surface water away from all proposed building sites and to an approved water course or storm sewer. Preliminary lot grading shall be completed at the time of street and utility installation to prevent water ponding on undeveloped lots. Finished grade at building foundation for all structures shall be a minimum of one foot above grade at the sidewalk or front lot line and shall be shown on the site grading plan for each lot. All structures are to be constructed at elevations that conform with Floodplain Regulations.
A grading and drainage plan shall be submitted, showing all existing and proposed storm sewers, manholes, catch basins, water courses, culverts, and other underground structures within the tract and immediately adjacent thereto, with pipe sizes and grades or waterway openings shown. Topographic contours to one foot shall be shown thereon. The plan shall show the method to be used for adequate disposal of all storm sewer water, including drainage outlets, and shall include a typical lot cross section drawn perpendicular to the street indicating lot grading and such other data as may be required by the Village Engineer. Such plans shall be drawn at a scale not less than 50 feet to the inch.
(Ord. 574. Passed 5-21-97.)
All streets within a subdivision shall be improved with a hard surface pavement with mountable concrete curb and gutter along each side. (Refer to illustration of "Typical Pavement" in Table 1 following Chapter 1113. The minimum width as measured from back of curb to back of curb shall be 25 feet.
The surface course of the street shall be constructed of either asphaltic concrete, bituminous mix, or Portland cement concrete. At a minimum, three-and-a-half (3.5) inches of asphaltic concrete on ten (10) inches of 304 aggregate base is required, or if concrete streets are proposed, a minimum of six ( 6) inches of Item 452 plain Portland cement concrete pavement on a four (4) inch item 310 subbase is required. Alternative materials and thicknesses may be approved or required as determined by the Village Engineer. All construction and materials specifications shall be in accordance with State of Ohio Department of Transportation Construction and Materials Specifications.
Minimum pavement gutter elevations shall be at or above hydraulic grade line for a ten (10)-year frequency storm.
Streets abutting the subdivisions that are not presently paved or curbed nor have a design grade on them will normally not be required to be paved at the time the subdivisions are to be constructed. However, all lots in the plat abutting such streets shall have included in their deeds or portions thereof, a waiver of objection for the assessment for paving, curbing, and draining. This waiver of objection is to be recited on the plat, and is to be an instrument of record affecting future title of properties.
All temporary dead end streets shall be provided with a T-type turnaround and a barricade consisting of a guardrail with adequate night reflectors at the end of the street.
(Ord. 574. Passed 5-21-97.)
In accordance with EPA regulations, a storm water permit may be required for discharge of storm water. Evidence of compliance with this requirement shall be provided.
Drainage laterals which include an adequate outlet shall be designed and constructed to provide for disposal of all surface water. Such design shall accommodate a five (5)-year frequency storm with the sewer pipe flowing full and a ten (10)-year frequency hydraulic grade line below the pavement low point. The drainage system shall, in addition, provide a drainage outlet a minimum of three (3) feet below the mean ground level for each lot. Drainage ditches shall be enclosed to accommodate the estimated ten (10)-year storm when the enclosure is equivalent in capacity to 48 inches in diameter or less. Such enclosures shall be constructed, installed and paid for by the subdivider. All ditches shall be enclosed within the new street right-of-way. Such enclosures shall be adequate to handle the storm drainage and shall be constructed, installed and paid for by the subdivider. Copies of calculations illustrating estimated volumes and peak flows of runoff shall be provided for review by the Village Engineer.
Detention of storm water runoff on-site may be required if, in the opinion of the Village Engineer, such detention is required to prevent down stream flooding.
Where flood plains are being reduced or eliminated by the site grading of the proposed subdivision, approval shall be obtained from the applicable agency as to the water course's adequacy to handle the additional water due to the altered land use collections. The 100-year flood plain elevation shall be shown on the preliminary drawing as well as on the final plat. The lowest finished floor elevations shall be a minimum of one foot above the regulatory 100-year flood plain. (Ord. 574. Passed 5-21-97.)
