The F-1 district is established and delineated on the zoning map to meet the needs of the Calumet Sag Channel, Stony Creek, Lucas Ditch and their tributaries to carry the abnormal flow of water at times of flood; to insure that the taxable value of land and buildings throughout the city are conserved; to prevent encroachments into the district which will unduly increase flood height and damage, and to prevent the loss of life and excessive damage to property in the area of greatest flood hazard.

(Ord. 280 § 7.00(1), 1968.)

The following uses are permitted:

A.

Open-type uses, such as loading and unloading areas, parking lots, storage of motor vehicles (new and used) for not more than twenty-four (24) hour periods, and gardens, auxiliary to uses permitted in adjoining district;

B.

Storage yards for equipment and materials in movable containers and not subject to major damage by flood, provided such uses are permitted in an adjoining district, but not including acids, caustics, flammable liquids, trash, rags, bottles, scrap metal or any other materials commonly referred to as junk;

C.

Open-type public and private recreational facilities, such as public parks, forest preserves, golf clubs, golf driving ranges, drive-in theaters, recreational lakes and other similar recreational uses, subject to all other provisions of this title;

D.

Agricultural uses, including farming, grazing and livestock raising, provided such uses are permitted in adjoining district;

E.

Any other uses customarily accessory or incidental to the above uses;

F.

Railroad rights-of-way and trackage;

G.

Planned residential developments in unsubdivided areas only; provided, that subsequent conditions of use have been satisfied;

H.

Single-family residences on lots of record prior to June 15, 1959; provided, that subsequent conditions of use have been satisfied.

(Ord. 280 § 7.00(2), 1968.)

The following special uses are permitted:

Seasonal residential uses, summer cabins, camps and cottages for seasonal and not permanent or year-round occupancy. The lot area and width of lot for such uses shall be as specified with the special use permit but in no case shall the lot area be less than 4000 square meters (one acre).

In the F-1 district, the following conditions of use shall pertain:

No filling of land shall be permitted except when approved by the plan commission and following a report from the city engineer and subject to such conditions as may be stipulated by Chapter 15.32 relating to flood hazards.

B.

The natural drainage grade shall not be substantially altered.

C.

Any structures permitted shall be placed on the lot so as to offer the minimum obstruction to the flow of water and shall be firmly anchored to prevent the structure from floating away and thus threatening to further restrict bridge openings and other restricted sections of the stream.

D.

Where, in the opinion of the plan commission, topographic data, engineering data and other studies are needed to determine the effects of flooding on a proposed structure and the effect of the structure on the flow of water, the plan commission may require the applicant to submit such data or other studies prepared by competent engineers or other studies prepared by competent engineers or other technicians.

E.

All uses permitted shall be subject to approval of the plan commission and to such conditions as may be stipulated to protect the public interest.

F.

No basement or other floor shall be constructed below the floodplain elevation.

G.

No building or structure shall be erected and no existing building or structure shall be moved unless the main floor elevation of said building or structure is established with a finished first floor elevation not less than that of the floodplain elevation.

H.

Planned single-family residential developments, where permitted, shall contain adequate storm drainage or other facilities capable of protecting the area from flooding.

I.

All planned single-family residential developments shall be subject to the final approval of the city council, based on recommendations from the plan commission and the city engineer that all of the foregoing requirements of this section have been complied with.

J.

All buildings and structures shall comply with the requirements stipulated in the chapter relating to flood hazards, Chapter 15.32.

(Ord. 280 § 7.00(4), 1968.)

Areas lying outside of and immediately adjacent to the floodplain district, as shown on the zoning map, shall be subject to the following regulations:

A.

No basement floor or other floor shall be constructed below or at a lower elevation than the elevation of the high-water mark for the ten-year recurrence interval.

B.

Land may be filled within the floodplain fringe areas, provided such fill shall extend at least 7½ meters (twenty-five feet) beyond the limits of any structure erected thereon.

C.

Foundations of all structures shall be designed to withstand flood conditions at the site.

(Ord. 280 § 7.00(5), 1968.)
