When an adequate public storm sewer is available at a plat boundary, the subdivider shall construct a storm sewerage system and connect such system with the line of such public storm sewer. If such a public storm sewer is not accessible, natural drainage channels with easements of adequate width shall be provided, as determined by the Municipal Engineer and approved by the Planning Commission. Paved gutters or storm sewers shall be required if velocities of flow are greater than specified in § 1250.21 or cause destructive erosion. Storm drainage, including drain tile around basements, shall not be permitted to discharge into any sanitary sewer facility, but shall connect to an adequate drainage outlet.
(Ord. 74-O-129, passed 10-17-1974)
Where natural drainage channels intersect a street right-of-way, the subdivider shall have satisfactory bridges and/or culverts constructed. Where culverts are required, the following minimum requirements shall be observed.
(a) All culverts shall extend across the entire right-of-way width of the proposed street. The cover over the culvert and its capacity shall be determined by the Municipal Engineer. The minimum diameter of a culvert pipe shall be 18 inches. Depending on existing drainage conditions, head walls may be required.
(b) Driveway culverts shall have a minimum length of 20 feet and a minimum diameter of 12 inches. Driveway culverts shall be laid so as to maintain the flow lines of the ditch or gutter. Head walls may be required.
(Ord. 74-O-129, passed 10-17-1974)
(a) Electric service and telephone service shall be provided within each subdivision. Gas service may be required where reasonably accessible and available. Whenever such facilities are reasonably accessible and available, they may be required to be installed within the area prior to the approval of the final plat. Telephone, electric and street lighting wires, conduits and cables shall be constructed underground, except in cases where the Municipal Engineer determines that topographic, bedrock or underground water conditions would result in excessive costs to the subdivider.
(b) Overhead utility lines, where permitted, shall be located at the rear of all lots. The width of the easement per lot shall be not less than five feet and the total easement width shall be not less than ten feet.
(c) Whenever a sanitary sewer line and an electric and/or telephone line are each placed underground in the same utility easement, the following provisions are applicable:
(1) The total easement width shall be not less than 20 feet.
(2) The sanitary sewer line shall be installed within three feet of one side of the easement and the electric and/or telephone lines shall be installed within three feet of the opposite side of the easement.
(Ord. 74-O-129, passed 10-17-1974)
The utilities, pavements and other land improvements required for a proposed subdivision shall be designed of oversize and/or with extensions provided to serve nearby land which is an integral part of the neighborhood service or drainage area, as determined by the municipality or County Engineer, whoever or whichever has jurisdiction.
(Ord. 74-O-129, passed 10-17-1974)
A subdivider shall be required to pay for only that part of the construction costs for the arterial streets, trunk sewers or water lines which are serving the proposed subdivision, as determined by the municipality or County Engineer. The municipality or county shall pay the difference between the cost of the required improvements for the proposed subdivision and the improvements required to service the surrounding areas specified in § 1250.24.
