§ 66-341. Drainage facilities.  


Latest version.
  • Pursuant to section 66-342, the subdivider shall provide stormwater drainage facilities which include curb and gutter, manholes, catchbasins and inlets, storm sewers, storm sewer laterals from the main to the lot line, road ditches and open channels, as may be required. All such facilities are to be of adequate size and grade to hydraulically accommodate maximum potential volumes of flow, the type of facility required, the design criteria and the sizes and grades to be approved by the common council designee. The design shall be based on current state stormwater rules. Such required improvements shall be dedicated to the city upon such terms and conditions as the common council may determine. Storm drainage facilities shall be so designed as to present no hazard to life or property, minimize shoreland erosion and siltation of surface waters, shall prevent excess runoff on adjacent property and shall provide positive drainage away from on-site sewage disposal facilities. There shall be no increase in stormwater runoff as a result of the development; the city may specify base runoff curve standards. The size, type and installation of all stormwater drain and sewers proposed to be constructed shall be in accordance with this chapter and plans and standard specifications approved by the common council designee. Storm drainage facilities shall be so designed as to minimize hazards to life or property, and the size, type and installation of all stormwater drains and sewers proposed to be constructed shall be in accordance with the plans and specifications approved by the common council designee. Storm sewers oversized to handle runoff from offsite properties will be installed by the subdivider; however, the cost of oversizing above a 24-inch diameter storm sewer shall be paid by the developer, with a right of recoupment when other users, other than the city, connect to the system.
