Eureka City Zoning Code
ARTICLE II
A St. Louis County Floodplain Non-Urban
Section 23-27 Purpose and Intent.
[Ord. No. 1511 §1, 2-20-2001]
(a)
The flood hazard areas of St. Louis County, Missouri, are subject to periodic inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare. These flood losses are caused by the cumulative effect of obstructions in flood plains causing increases in flood heights and velocities and by the occupancy of flood hazard areas by uses vulnerable to floods or hazardous to other lands which are inadequately elevated, floodproofed, or otherwise protected from flood damages.
(b)
This Section is therefore necessary to protect human life and health; to minimize expenditure of public money for costly flood control projects; to minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; to minimize prolonged business interruptions; to minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains; and to help maintain a stable tax base by providing for the sound use and development of flood-prone areas in such a manner as to minimize future flood blight areas.
(c)
It is the purpose of this Section to promote the public health, safety and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to restrict or prohibit uses which are dangerous to health, safety and property due to water or erosion or in flood heights or velocities; to require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; to control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of floodwaters; and to control filling, grading, dredging, and other development which may increase erosion or flood damage.
Section 23-27.1 Scope of Provisions.
[Ord. No. 1511 §1, 2-20-2001]
(a)
This Section contains the regulations for the "FP" Floodplain District of St. Louis County. Property zoned "FP" is also zoned under another applicable district governed by the St. Louis County zoning ordinance. The "FP" District constitutes an "overlay" district, and the other applicable zoning district constitutes the underlying zoning. This Section controls in the case of any conflict between the regulations contained in this Section and the regulations otherwise applicable to any property by virtue of its "underlying" zoning.
(b)
All of the area within the "FP" District is the floodplain, as defined in this Chapter, and is subject to all of the provisions of this Section. A portion of the area within this district is designated as the floodway, as established by the maps applicable to this district. Property within the floodway is subject to those provisions of this Section which so state.

[Ord. No. 1511 §1, 2-20-2001]
All development or use of the floodway is prohibited involving any encroachment, including fill, new construction or material improvement of any existing structure unless certification by a registered professional engineer is provided to and approved by the Department of Highways and Traffic that the development will not result in any increase in flood levels during occurrence of the base flood discharge. If and only if this Section is complied with, use or development of the floodway may be carried out subject to the restrictions of the remainder of this Article.
Section 23-28.6 Use and Development Under Underlying District Regulations.
[Ord. No. 1511 §1, 2-20-2001]
Property in this district may be used and developed in accordance with the regulations of the underlying zoning upon compliance with the following procedure:
(1)
The property is placed in such conditions as to effectively and without increasing the flooding problems of other properties, remove the property from flooding based on the flood elevation study approved by the United States Federal Emergency Management Agency ("FEMA") and used as basic data for determining the boundaries of the Flood Hazard Boundary Map, being the "FP" Floodplain District as governed by this Section. Effective removal of the property from flooding requires provision of adequate freeboard as determined by the Department of Highways and Traffic in light of the reasonably anticipated ultimate development of the watershed. If the standards required by this Subsection are satisfactorily met in respect to any lot or tract of land in the "FP" Floodplain District, the property may then be used for such uses and under such regulations as are contained in the district regulations of the district designated after the "FP" code designation as the underlying district for the particular property.
(2)
(a)
The property owner or user shall submit to the Department of Highways and Traffic a plan for flood protection. The plan shall be approved if its implementation would adequately protect against the amount of water that would flow past the property in cubic feet per second during the base flood, as determined by the flood elevation study approved by FEMA and used as basic data for determining the boundaries of the Flood Insurance Rate Map and the Flood Hazard Boundary Map, and if the plan further demonstrates that its implementation will not increase the flooding problems of other properties. With respect to any stream for which a floodway has not been designated, except the Mississippi River, the flooding problems of other properties will be deemed increased if implementation of the plan would decrease the water storage or conveyance capacity of the stream.
(b)
The plan must include a report by a registered professional engineer of demonstrated competence in hydrology as to the adequacy of the proposed plan for flood protection relative to the elevation of the floodplain and the flow as determined in the flood elevation study approved by FEMA, the effect of the proposed improvement on the flood problems of other properties, and such other hydrologic problems as may result from the improvements. Where the plan only delineates the floodplain elevation on the ground and no change or construction is proposed involving land below the floodplain elevation, the plan may be submitted under the seal of a registered land surveyor.
(c)
The Department of Highways and Traffic may require such additional data or engineering studies from the applicant as may be necessary to determine the adequacy of the proposed plan for flood protection.
Section 23-28.7 Use and Development in the "FP" Floodplain District.
[Ord. No. 1511 §1, 2-20-2001]
No use or development in this district shall increase the flooding problems of other properties. Prior to any use or development of property pursuant to the permitted or conditional uses designated in this district, if such use or development involves manmade change to real property below the flood elevation, including construction or erection of any building or structure, or any filling, grading, paving, mining, dredging, excavation or drilling, the following procedure shall be complied with:
(1)
The property owner or user shall submit to the Department of Highways and Traffic a development plan. The plan shall be approved if it demonstrates that its implementation will not increase the flooding problems of other properties. With respect to any stream for which a floodway has not been designated, the flooding problems of other properties will be deemed increased if implementation of the plan would decrease the water storage or conveyance capacity of the stream.
(2)
The plan shall include a report by a registered professional engineer of demonstrated competence in hydrology as to the adequacy of the proposed plan to avoid flooding problems of other properties and such other hydrologic problems as may result from the improvements. Where the plan only delineates the floodplain elevation on the ground and no change or construction is proposed involving land below the floodplain elevation, the plan may be submitted under the seal of a registered land surveyor.
(3)
The Department of Highways and Traffic may require such additional data or engineering studies from the applicant as may be necessary to determine the adequacy of the proposed plan.
Section 23-28.8 Effect of Plan Approval.
[Ord. No. 1511 §1, 2-20-2001]
(a)
The approval by the Department of Highways and Traffic of such plans for flood protection does not constitute a representation, guarantee or warranty of any kind by St. Louis County, the Department of Highways and Traffic, the St. Louis County Planning Commission or by any officer or employee of either as to the practicality or safety of any protective measure and shall create no liability upon or cause of action against such public body, officers or employees for any damage that may result pursuant thereto.
(b)
Approval of the plan by the Department of Highways and Traffic does not relieve an owner or user from fulfilling the requirements set forth in any other County ordinance regarding construction or development within the floodplain.
