(a) The subdivider shall construct a storm sewer system and connect with an adequate public storm sewer main. If such storm sewer systems are not accessible, adequate provision shall be made for the disposal of storm waters, subject to the specifications of the Municipal Engineer, in accordance with the Storm Water Design Manual. However, in subdivisions containing residential lots less than 15,000 square feet in area and in all commercial and industrial districts, underground storm sewer systems shall be constructed to service all street and parking lot storm water runoff and be conducted to an approved outfall.
(b) In all cases where no storm sewer mains exist, but their extension is planned, in accordance with information contained in the current Comprehensive Plan and the sewer facilities plan, then the developer must provide an underground storm sewer system with approved outfall to service all streets and parking lots, until such extension is made, at which time connection shall be made.
(c) The size of storm sewers should not be based solely on present needs, but rather on the contemplated population density of the drainage basin. The reimbursement to the developer for the oversized portion of the storm sewer line shall be made in accordance with the procedures established by the Planning and Zoning Commission with the approval of Council. It is the intent of these Subdivision Regulations that future benefitting developers shall reimburse the original developer, or the Municipality if the Municipality participated in the financing of the original over sizing of the storm sewer. Storm drainage, including drain tile around basements shall not be permitted to discharge into any sanitary sewer facility.
