§ 26-8. Drainage.
(1)
Permit to construct or alter drainageways. No person shall construct, deepen, widen, fill, reroute or alter any existing drainageway, ditch, drain or canal without first obtaining a written permit from the city. Plans for all such work shall comply with the engineering design standards manual and rights-of-way for such work must be dedicated to the use of the public or deeded in fee simple or by easement as may be required by the city to a proper governmental water control district. Such dedication or deed shall be made prior to any such construction or alteration.
(2)
Rights-of-way and easements. Whenever any drainageway, stream or surface drainage course is located or planned in any area that is being subdivided, the subdivider shall dedicate in fee simple or easement such stream or drainage course with an adequate right-of-way necessary for maintenance, future expansion and other purposes along each side of such stream or drainage course as is determined by uniform standards prescribed by the engineering design standards manual. Utility easements and drainage easements should not be combined or overlap and drainage easements shall take precedence.
(3)
Stormwater. Adequate provision shall be made for the disposal of stormwater subject to standards prescribed in the engineering design standards manual and in conformance with the city's master secondary drainage plan.
(4)
Contour map and drainage of adjacent areas. A contour map shall be prepared and submitted by a state-registered land surveyor or engineer for the area comprising the subdivision and such additional areas as may be required by the city's civil engineer necessary to include all watersheds which drain into or through the property to be developed, provided that this map of the adjacent areas may be prepared from existing maps or other data available to and acceptable by the city's civil engineer. The design for drainage of the subdivision must be adequate to provide for drainage of adjacent watershed areas, and design or drainage structures must provide for drainage of adjacent watersheds after complete development of the total area. Where ditches and canals are required, rights-of-way shall be provided for future needs in accordance with uniform standards prescribed in the engineering design standards manual. The developer may be permitted by the city's civil engineer to excavate, open or construct necessary drainage facilities of sufficient capacity to provide for existing drainage needs whenever the developed or undeveloped status of adjacent watersheds may warrant as determined by the city's civil engineer.
(5)
Off-site drainage. Off-site drainage shall be mutually coordinated by and between the subdivider, the development services director and the city's civil engineer.
