Summary
Redding's 'FP' Floodplain Overlay District, adopted to keep the city eligible for the National Flood Insurance Program, splits every mapped floodplain into a floodway where development is largely prohibited and a flood fringe where only limited or use-permitted activity is allowed. Structures other than those specifically listed cannot be located in the floodway at all under Section 18.51.040.
A.Applicability. The regulations of this chapter provide seven levels of protection within and along waterways of the "FP" Floodplain Overlay District by (1) generally prohibiting development within the floodway, (2) allowing only limited use and development in the flood fringe, (3) regulating uses and development on properties contiguous to the flood fringe and outside of the floodplain, which do not meet the minimum protection standards...Structures or insurable improvements other than those listed in Sections 18.51.060 and 18.51.070 of this chapter shall not be located within the floodway.

Full Breakdown
51 layers seven levels of protection onto property in and along Redding's waterways: it generally bars development in the floodway, allows only limited uses in the flood fringe, imposes lesser standards on land contiguous to the flood fringe, adds scenic-corridor review, and requires every development permit in the district to be checked for flood safety and flood-carrying capacity before approval. Inside the floodway and flood fringe, uses such as storage of buoyant, explosive, or toxic materials, parking or storing recreational vehicles, fences or walls other than street-arterial walls with flood openings, and swimming pool equipment are flatly prohibited unless the site is raised to the flood protection elevation through an approved encroachment application.
A short list of uses is permitted outright without a use permit, including emergency actions ordered by the city manager, removal of flood-deposited debris under a grading permit, normal maintenance of existing channels and levees, and bridges engineered to pass a hundred-year flood without impeding floodwaters. 080. Outside the floodway and flood fringe but still inside the FP district, new construction must set back thirty feet from the Sacramento River or fifteen feet from any creek, with the lowest floor at least one foot above the base floodplain elevation.
Violations & Fines
Grading, filling, or building in the base floodplain without the approvals this chapter requires is prohibited outright under Section 18.51.030(B)(1). Development that would raise the base flood elevation is barred unless the applicant obtains a FEMA map revision and written consent from every property owner affected by the higher water level, and any structure placed in the floodway that is not on the permitted-use list can be required to be raised to the flood protection elevation or removed as a nonconforming use.
