East Bethel City Zoning Code

SECTION 58

- FLOODPLAIN MANAGEMENT FP OVERLAY DISTRICT

1.- Title, applicability and authority.

A.

Purpose. The purpose of the floodplain (FP) management district is to regulate the use of creeks, associated lakes, drainageways, and adjacent properties in order to minimize the loss of life, loss of 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 caused by the periodic inundation by flood waters. The intent is to apply the regulations and standards of this district as an overlay zone, further regulating the use of land as allowed by the other use districts of this ordinance.

A.[B.]

Applicability. This district shall apply to those areas in East Bethel which are identified in this subdivision as being subject to inundation by the 100-year flood as established in subpart 3 of this subdivision [section 58].

2. - Conditional uses.

Electric power and communications transmission lines.

3. - General provisions.

A.

Warning and disclaimer of liability. This subdivision does not imply that properties outside the floodplain areas or land uses permitted within such areas will be free from flooding or flood damages. This subdivision shall not create liability on the part of the city or any officer or employee for any flood damages that result from reliance on this subdivision or any administrative decision made concerning this subdivision of this ordinance.

A. [B.]

Permits. Permits from the city are required by this subdivision for the use of land and for the construction, addition, or alteration of any structure, obstruction, public or private sewage treatment system, and the grading and filling of the natural topography. Permit applications shall include elevations of the lot and lowest floor of all structures, and the location of the stream channel, its floodplain, and flood fringe.

A. [C.]

Water supply and sewage disposal. The provisions of Chapter 4725, Department of Health Water Well Construction Code and MPCA Water Quality Division, Individual Sewage Treatment Systems Standards, Chapter 7080, shall apply to all properties within the FP district.

4. - FP zoning district.

A[1].

FP district boundaries. The boundaries of the FP zoning districts shall be as shown in the Flood Insurance Study (November 1979), Flood Insurance

A[2].

Rate maps (May 15, 1980), and flood boundary and floodway maps (May 15, 1980) for East Bethel prepared by the Federal Insurance Administration which are on file with the city are hereby adopted by reference and made a part of this ordinance.

B.

The areas delineated in the official zoning map as studied areas and/or numbered A zones, shall be considered a general delineation of the area subject to the "regional flood" or "base flood" and shall be subject to field evaluation of the actual conditions. Where there appears to be a conflict between the mapped boundary and the regional flood elevation, the city may use whichever delineation establishes the greater flood protection. If adequate soil borings and elevations show a possible error in the mapping, and after reviewing the date and site evaluation, a waiver for development may be granted or greater restrictions imposed.

C.

The areas delineated in the official zoning map as unnumbered A zones shall be considered a general delineation of the area subject to the "regional flood" or "base flood" and shall be subject to field evaluation based on the specific soil conditions present. The general floodplain boundary may be expanded or reduced as may be justified by the presence or absence of soils, in or adjacent to the mapped area, that may be subject to flooding.

D.

Applicants for permits in delineated floodplain areas where the regional flood elevation has not been established by this subdivision may be required to submit an engineering report and plans establishing the elevation of the regional flood with the application.

[A[2]. 1) and 2)], or any use of land that does not comply with the standards in b.3.) and 4.) of this subpart [A[2]. 3) and 4)], shall only be allowable as a conditional or interim use.

A[4].

Standards for FF area conditional and interim uses. The following standards shall apply to conditional uses in the FF area:

1)

Alternative elevation methods other than the use of fill may be utilized to elevate a structure's lowest floor to or above the RFPE. These alternative methods may include, but are not necessarily limited to, the use of stilts, pilings, parallel walls, or above-grade enclosed areas such as crawl spaces or tuck-under garages. The base or floor of an enclosed area shall be considered above-grade and not a structure's basement or lowest floor if the enclosed area is: 1) above-grade on at least one side of the structure, 2) is designed to internally flood and is constructed with flood resistant materials, and 3) is used solely for parking of vehicles, building access, or storage. The above-noted alternative elevation methods are subject to the following additional standards:

a)

The structure's design and as-built condition must be certified by a registered professional engineer, certified building official, or architect as being in compliance with the general design standards of the state building code and, specifically, that all electrical, heating, ventilation, plumbing, air conditioning equipment, and other service facilities must be at or above the RFPE or be designed to prevent flood water from entering or accumulating within these components during times of flooding.

b)

Above-grade, fully-enclosed areas such as crawl spaces or tuck-under garages must be designed to internally flood and the design plans must stipulate:

(1)

The minimum area of openings in the walls where internal flooding is to be used as a flood-proofing technique. When openings are placed in a structure's walls to provide for entry of flood waters to equalize pressures, the bottom of all openings shall be no higher than one foot above grade. Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of flood water.

(2)

That the enclosed area will be built with flood-resistant materials in accordance with the FP-3 or FP-4 classifications in the state building code and shall be used solely for building access, parking of vehicles, or storage.

2)

Basements as a conditional or interim use shall be subject to the following standards:

a)

Residential basement construction shall not be allowed below the RFPE.

b)

Non-residential basements may be allowed below the RFPE provided the basement is structurally dry flood-proofed in accordance with b.3.) [A[2].3)] of this subpart.

3)

All areas of non-residential structures including basements to be placed below the RFPE shall be flood-proofed in accordance with the structurally dry flood-proofing classifications in the state building code. Structurally dry flood-proofing must meet the FP-l or FP-2 flood-proofing classification in the state building code and this shall require making the structure watertight with the walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy. Structures flood-proofed to the FP-3 or FP-4 classification shall not be permitted.

4)

When at any one time more than 1,000 cubic yards of fill or other similar material is located on a parcel for such activities as on-site storage, landscaping, sand and gravel operations, landfills, roads, dredge spoil disposal, or construction of flood control works, an erosion/sedimentation control plan must be submitted. The plan must clearly specify methods to be used to stabilize the fill on-site for a minimum 100-year flood level event. The plan must be prepared and certified by a registered professional engineer or other qualified individual acceptable to the city. The plan may incorporate alternative procedures for removal of the material from the floodplain if adequate flood warning time exists.

5)

Storage of materials and equipment as a conditional use shall be subject to the following standards:

a)

The storage or processing of materials that are, in time of flooding, flammable, explosive, or potentially injurious to human, animal, or plant life is prohibited.

b)

Storage of other materials or equipment may be allowed if readily removable from the area within the time available after a flood warning and in accordance with a plan approved by the city.

6)

The provisions of subpart e. of this subpart [A[5] of this item 6] shall also apply.

A[5].

Standards for all flood fringe (FF) uses. The following standards shall apply to all uses in the FF district:

1)

All new principal structures must have vehicular access at or above an elevation not more than two feet below the RFPE. If a variance to this requirement is granted, the planning commission must specify limitations on the period of use or occupancy of the structure during times of flooding. A variance may be granted only after a finding is made by the city council that adequate flood warning time and local flood emergency response procedures exist.

2)

Accessory commercial land uses, such as yards, railroad tracks, and parking lots may be at elevations lower than the RFPE. Such uses are allowed only by permit issued by the city. However, a permit for such facilities to be used by the employees or the general public shall not be granted in the absence of a flood warning system that provides adequate time for evacuation if the area would be inundated to a depth greater than two feet or be subject to flood velocities greater than four feet per second upon occurrence of the regional flood.

3)

Measures shall be taken to minimize interference with normal manufacturing and industrial plant operations, especially along streams having protracted flood durations. Certain accessory land uses such as yards and parking lots may be at lower elevations subject to requirements set out in 2.) above. In considering permit applications, due consideration shall be given to needs of an industry whose business requires that it be located in floodplain areas.

4)

Fill shall be properly compacted and the slopes shall be properly protected by the use of riprap, vegetative cover, or other acceptable method. The Federal Emergency Management Agency (FEMA) has established criteria for removing the special flood hazard area designation for certain structures and property elevated on fill above the 100-year flood elevation. FEMA's requirements incorporate specific fill compaction and side slope protection standards for multi-structure or multi-lot developments. These standards should be investigated prior to the initiation of site preparation if a change of special flood hazard area designation will be required.

5)

Development in the floodplain shall not adversely affect the hydraulic capacity of the channel and adjoining floodplain of any tributary, watercourse, or drainage system where a floodway or other encroachment limit has not been specified on the official zoning map.

6)

Travel trailers and travel vehicles shall comply with the requirements contained in subpart 7.e [A[5] of item 7 of this section 58].

7)

All manufactured homes must be securely anchored to an adequately anchored foundation system that resists flotation, collapse, and lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state or local anchoring requirements for resisting wind forces.

7. - General floodplain (GF) district.

A[1].

Permitted uses. The following shall be permitted uses in the general floodplain (GF) district:

1)
