Chapter 153 — FLOOD HAZARD AREA REGULATIONS

§ 153.022 FLOODWAYS.

Eureka Zoning Code · 2026-06 edition · updated 2026-07-25 · Eureka

Since floodways are an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following provisions apply:

(A) Until a regulatory floodway is adopted, no new construction, substantial development, or other development (including fill) shall be permitted within Zones A1-30 and AE, unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other development, will not increase the water surface elevation of the base flood more than one foot at any point within the city.

(B) Within an adopted regulatory floodway, the city shall prohibit encroachments, including fill, new construction, substantial improvements, and other development, unless certification by a registered civil engineer is provided demonstrating that the proposed encroachment shall not result in any increase in flood levels during the occurrence of the base flood discharge.

(C) If § 153.022(A) and (B) are satisfied, all new construction, substantial improvement, and other proposed new development shall comply with all other applicable provisions for flood hazard reduction.

(Ord. 767-C.S., passed 4-19-11)
