(a) It shall be unlawful for any person or organization to construct, enlarge, alter, repair, relocate, or demolish a storm sewer, natural watercourse, or other storm water facility without first filing an application and obtaining a proper permit from the City. Permits for minor repairs, as defined in the rules and regulations, shall not be required.
(b) (1) Permits are required and may be granted by the City for the following improvement categories:
A. Connection into the public storm water system, except unimproved creeks or streams.
B. Improvements which are or will become public facilities.
C. Improvements within dedicated but unimproved street rights-of-way.
D. Improvements which require retention or detention facilities.
(2) Notwithstanding anything to the contrary herein, permits issued under this division (b) shall not be required in instances where the City's approval of the proposed storm sewer improvements are obtained by an owner as part of the City's subdivision approval process.
(c) Plans for all improvements made within the City that require storm water facilities or changes or alterations to existing storm water facilities must be submitted to the City Engineer or his or her designee for review and approval. Plans and applications may be submitted directly to the City Engineer or his or her designee or through the building permit process. All improvements must conform to the provisions of this chapter or rules or regulations promulgated hereunder and the master plan. The City Engineer, or his or her designee shall have 30 days after the date of application to review each plan submitted. Plans that are not approved may be resubmitted after revisions are made. No permit shall be issued until a plan is approved or the need for a permit is waived by the City Engineer or his or her designee.
(d) Every improvement shall be provided with a storm water system capable of handling storm waters flowing onto the improvement site from other areas as well as storm water from the site itself. The drainage system shall be designed to discharge into a watercourse, drainage channel or other existing storm water facility. These designs shall conform to the guidelines listed below and the specifications prescribed in the rules and regulations.
(e) For lots to be developed and where new structures, additions, or changes are to be made, adequate surface grading shall be extended or runoff shall be collected in inlets and then connected to sewers or drains. The proposed grading and necessary drains shall be shown on the building permit site plan. The plan shall then be reviewed by the City Engineer or his or her designee and approved when sufficient revisions are made as deemed necessary.
(f) For all lots being developed, plans will designate that all areas shall be graded and drained to prevent the standing of storm water, except lakes, lagoons, or retention reservoirs approved by the City. Where necessary, drainage channels or sewers shall be provided to convey the water to an existing watercourse or outlet. The method and means of drainage, including the handling of both paved and unpaved areas, shall be subject to approval by the City Engineer or his or her designee.
(g) Facilities shall be provided to drain all street intersections, and to care for roof downspouts and drains from yards and driveway aprons. Where foundation drains are installed, the foundation drains must discharge to the drainage system directly or through a sump pump installation. In no case will pumped storm water be discharged directly to or through the curb or to a public or private road.
(h) The storm water drainage system shall not be combined with any part of the sanitary sewer system, nor shall sanitary waste water be discharged to the storm water drainage system.
(i) Connection into a storm sewer shall be by permit only and in the presence of the City Inspector to ensure proper methods are observed in accordance with City standards.
(j) Contractors must post a bond in the amount required by the Director of Public Service. Such amount shall not exceed the amounts required by the City for work done in any right-of-way.
