Chapter 18.132

The regulations set out in this chapter shall apply to land lying outside the boundaries of all airports in the city, or located contiguous thereto, where the takeoff or landing patterns involve flight over land within the city. (Ord. 1000 § 44, 1955)

A. No building or structure may be erected, structurally altered or enlarged within lines which define the flight zone for landing strips or aircraft runways unless the height of such building shall be below a line defined as the angle of glide.

B. The "angle of glide" means and is defined as beginning at the end of the takeoff or landing strip and having an angle described by a one foot (1') vertical rise for every forty feet (40') of horizontal run. All existing buildings lying within this area which do not comply with this provision are hereby declared to be nonconforming, and are subject to such action as may be prescribed by law.

C. No building shall be more than one story or twenty feet (20') in height within one thousand feet (1,000') of the exterior boundaries of any airport.

D. The provisions of the Redlands municipal airport airspace zoning ordinance regulating and restricting the height of structures, object of natural growth, and otherwise regulating the use of airspaces, shall apply to land lying outside the boundaries of the Redlands municipal airport. (Ord. 1000 § 44.00(a)–(c), 1955)

The purpose of the FP floodplain district is to provide for the protection of the public health, safety and general welfare in those areas of the city which, under present conditions, are subject to periodic flooding and accompanying hazards. (Ord. 1000 § 31.60, 1955)

The objectives of the floodplain district shall be:

A. To prohibit occupancy or the encroachment of any structure, improvement or development that would obstruct the natural flow of floodwaters within a designated floodway on the floodplain;

B. To keep developments in the remainder of the floodplain above the design flood flow elevation;

• C. To prevent economic loss caused by excessive flooding, and to prevent loss of life or property. (Ord. 1000 § 31.61, 1955)

As used in this chapter:

DESIGN FLOOD: The selected flood against which protection is provided, or eventually will be provided, by means of flood protective or control works. When a federal survey has been authorized, the design flood will be determined by the appropriate federal agency, and in all other cases it will be determined by the San Bernardino County flood control district. It is the basis for design and operation of a particular project after full consideration of flood characteristics, frequencies and potentials, and economic and other practical considerations.

FLOOD: Any temporary rise in stream flow or water surface level that results in significant adverse effects in the floodplain. "Adverse effects of floods" may include damages from overflow of land areas, effects of temporary backwater on sewers and local drainage channels, bank erosion or channel shifts, unsanitary conditions, or other unfavorable conditions resulting from deposition of materials in stream channels during flood recessions, rise of ground water coincident with increased stream flow, and interruption of traffic at bridge crossings.

FLOODPLAIN: The relatively flat area or lowlands adjoining the channel of a stream or watercourse, and subject to overflow by floodwaters.

FLOODPLAIN ZONING: The floodplain of the design flood shall be divided into two (2) zones for regulation purposes:

A. Zone FP-1, Designated Floodway: The channel of a stream and that portion of the adjoining floodplain required to reasonably provide for the construction of a project for passage of the design flood, including the lands necessary for construction of project levees;

B. Zone FP-2, Restrictive Zone: The portion of the natural floodway between the limits of the designated floodway and the limits of the floodplain, as determined by the selected flood, where inundation may occur but where depths and velocities are generally low. (Ord. 1000 § 31.62, 1955)

No building, structure or land shall be used, and no building or structure shall be hereafter erected, structurally altered or enlarged, except for the purposes set out in sections 18.136.050 through 18.136.070 of this chapter. (Ord. 1000 § 31.63, 1955)

Principal permitted uses include:

A. FP-1 district:

Flood control channels, levees and spreading grounds, and basins, roads, bridges and diversion drains, where plans are approved by the San Bernardino County flood control district.

Grazing, field crops, truck gardening, berry and bush crops, flower gardening, wildlife preserves, forest preserve, and similar open or agricultural uses.

B. FP-2 district:

All uses permitted in the FP-1 district.

Orchards, tree crops, nurseries for producing trees, vines and other horticultural stock, and similar open or agricultural uses. (Ord. 1000 § 31.63(A), 1955)

The commission may, by resolution of record, permit any other uses which it may determine to be similar to those listed in section 18.136.050 of this chapter, in conformity with the intent and purpose of the FP zone, and not more obnoxious or detrimental to the public health, safety and welfare, or other uses permitted in this zone. (Ord. 1000 § 31.63(B), 1955)

The following uses are permitted by conditional use permit:

A. FP-1 district:

None.

B. FP-2 district:

Excavation and removal of rock, sand and gravel.

Recreation areas, parks, playgrounds, fishing lakes, golf courses, polo fields, baseball and football fields, parking lots, and similar uses involving the open use of land without structures or improvements, where it can be shown that the natural flow of floodwaters or storm waters would not be obstructed. (Ord. 1000 § 31.63(C), 1955)

Structures existing at the effective date of any application of the FP zone which are inconsistent with the provisions thereof, will be allowed to remain under the conditions set forth in chapter 18.184 of this title, except that:

A. If the useful life of a structure has not expired by a date fifteen (15) years after the effective date of the application of the FP zone, the life of the structure shall be considered to have expired automatically, and the structure shall be removed;

B. Any existing structure damaged in excess of seventy five percent (75%) of its reasonable value, by fire, explosion, floods, acts of God or the enemy, shall be removed;

C. The enlargement, expansion, extension or change in use of any structure is not permitted. (Ord. 1000 § 31.65, 1955)

For nonconforming uses of land in the FP zones, the provisions of section 18.184.030 of this title shall apply. (Ord. 1000 § 31.66, 1955)
