STORM WATER SYSTEM, FLOODPLAIN AND OTHER STANDARDS, SOIL EROSION CONTROL
The City is not responsible for providing drainage facilities on private properly for the management of storm water on said property. It shall be the responsibility of the property owner to provide for, and maintain, private storm water runoff facilities serving the property and to prevent or correct the accumulation of debris that interferes with the drainage function of a water body.
(Ord. 07-2002-10. Passed 7-2-02.)
The City is authorized to establish minimum design standards for storm water discharge release rates and to require dischargers to implement on-site retention, detention or other methods necessary to control the rate and volume of surface water runoff discharged into the storm water drainage system, in the following circumstances:
(a) A parcel of land is being developed an a manner that increases the impervious surface area of the parcel; or
(b) The discharge exceeds the City-calculated pre-development discharge characteristics for the subject property, and the City determines that the discharge is a violation of the drainage, flooding or soil erosion regulations of this chapter.
(Ord. 07-2002-10. Passed 7-2-02.)
(a) All new buildings and substantial improvements to existing buildings shall be protected from flood damage up to the Flood Protection Elevation (FPE) and shall be in accordance with all applicable Federal, State and local ordinances, and rules and regulations. Floodway alteration shall be permitted only upon review and approval by the City, in accordance with an approved drainage plan.
(b) A drainage plan. providing for the filling or alteration of a floodway may include provisions for maintaining stability of the banks of streams or other water bodies, by means of the establishing of buffer zones and other means of providing protection of the slopes and banks of water bodies.
(c) Within any required buffer zone, no earth change shall take place except in accordance with the approved drainage plan. Such a plan may also include provisions for the replacement of floodplain storage volume, where such storage volume is lost or diminished as a result of approved development.
(Ord. 07-2002-10. Passed 7-2-02.)
(a) All persons who cause, in whole or in part, any earth change to occur shall provide soil erosion and sedimentation control so as to adequately prevent soils from being eroded and discharged or deposited onto adjacent properties or into a storm water drainage system, a public street or right-of-way, wetland, creek, stream, water body, or floodplain. All development shall be in accordance with all applicable Federal, State and local ordinances, rules and regulations.
(b) During any earth change which exposes soil to an increased risk of erosion or sediment track-out, the property owner and other persons causing or participating in the earth change shall do the following:
(1) Comply with the storm water management standards of this chapter.
(2) Obtain and comply with the terms of a soil erosion and sedimentation control permit if required by law.
(3) Prevent damage to any public utilities or services within the limits of grading and within any routes of travel or areas of work of construction equipment.
(4) Prevent damage to or impairment of any water body on or near the location of the earth change or affected thereby.
(5) Prevent damage to adjacent or nearby land.
(6) Apply for all required approvals or permits prior to the commencement of work.
(7) Proceed with the proposed work only in accordance with the approved plans and in compliance with this chapter.
(8) Maintain all required soil erosion and sedimentation control measures, including but not limited to, measures required for compliance with the terms of this chapter.

(a) No building opening shall be constructed below the following elevations:
(1) One foot above the 100-year floodplain.
(2) The building opening established at the time of plat or development approval and on file in the City Engineering Department.
(3) Three feet above the top of any downstream culvert.
(4) Four feet above the bottom of any permanent and defined drain.
(b) A waiver from elevations stated in Section 1043.19(a) may be granted by the City Engineer following receipt of a certification from a registered professional engineer demonstrating that the proposed elevation does not pose a risk of flooding.
(c) Upon completion of construction of the structure's foundation and/or slab on grade, a registered land surveyor shall certify any minimum building opening elevation specified by this chapter. This certificate shall attest that the building opening elevation complies with the standards of this chapter. The permittee for the building permit shall submit the certificate to the City Building Inspections official prior to the commencement of framing and/or structural steel placement. If the surveyor should find that the minimum building opening elevation is below the elevation specified in division(a)(2) or (3) of this section, that opening must be raised using a method that meets with the approval of the City. After reconstruction, a registered land surveyor or engineer shall re-certify that the minimum building opening elevation complies with the standards of this chapter prior to the commencement of framing and or structural steel placement.
