Part 21 — F-P FLOODPLAIN DISTRICT

The purpose and intent of the Floodplain District is to protect the public health, safety, and welfare through regulations of uses in areas which are unprotected from flooding or are required to carry the flood flows of a stream. New construction in the Floodplain District is regulated so that it is protected against damage and located to avoid causing excessive increases in flood heights or velocities. This section of the Zoning Ordinance is also part of the Local Coastal Implementation Plan. (Ord. 94-33 § 49, 1994: Ord. 85-05 § 1 (part), 1985).

1. Accessory dwelling units on parcels with an approved residential use, subject to the provisions of Chapter 24.16, Part 2;

   2. Agriculture;

   3. Crop and tree farming;

2. Nurseries.

(Ord. 2024-17 § 29, 2024; Ord. 85-05 § 1 (part), 1985).

Garages, barns, and other structures customarily appurtenant to a permitted use. (Ord. 85-05 § 1 (part), 1985).

1. The following uses are subject to approval of an administrative use permit and

may also require a design permit per Section 24.08.410:

a. Ranch and farm dwellings incidental to a principal agricultural use.

b. Wireless telecommunications facilities, subject to the regulations in Chapter 24.12, Part 15.

2. The following uses are subject to approval of a special use permit and a design permit:

a. Recreational facilities, bridges, roads, utility transmission lines;

b. Riding stables for the keeping of horses on sites at least five acres in size. (Ord. 2022-19 § 33, 2022; Ord. 85-05 § 1 (part), 1985).

Any other use or service establishment determined by the zoning administrator to be of the same general character as the foregoing uses, and which will not impair the present or potential use of adjacent properties, may be permitted. If the zoning administrator determines that the proposed use is more in character with the conditional uses for this zone, then a use permit shall be required and processed pursuant to Part 1, Chapter 24.08, Use Permits. The decision as to whether the use determination requires an administrative use permit or a special use permit shall be based on the use category that is most similar to the proposed use as determined by the zoning administrator.

(Ord. 2022-19 § 34, 2022; Ord. 85-05 § 1 (part), 1985).

The following requirements will be observed in the F-P District for the type of use proposed; except as otherwise provided in this title.

d. Fill incidental to a principally permitted or conditional use must be accompanied by a plan showing the uses to which the fill land will be placed, final dimensions of proposed fill, and effects on the capacity of the floodway and flood heights.

e. Environmental assessment shall be required of conditional uses to determine the requirements of the use permit that minimize hazards to public health and safety. (Ord. 2024-17 § 30, 2024; Ord. 85-05 § 1 (part), 1985).
