Such certification and verification shall be provided to the Floodplain Administrator.
(Code 2002, § 34-94. Ord. No. 10-1)
15.75.210 Floodways.
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 1 foot at any point within the city; or establish a setback from the stream bank equal to five times the width of the stream at the top of the bank or 20 feet on each side from the top of the bank, whichever is greater.
(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 subsections 15.75.210(a) and 15.75.210(b) are satisfied, all new construction, substantial improvement, and other proposed new development shall comply with all other applicable flood hazard reduction provisions of this Article IV.
(Code 2002, § 34-95. Ord. No. 10-1)
Article V. Pine and Galindo Creek Floodway Regulations
15.75.220 Definitions.
The definitions set forth in the Colby-Alquist Flood Plain Management Act, Water Code §§ 8400-- 8415, are incorporated in this section as if specifically set forth herein. (Code 2002, § 34-121. Ord. No. 10-1)
15.75.230 Designation of floodway.
The definitions set forth in the Colby-Alquist Flood Plain Management Act, Water Code §§ 8400-- 8415, are incorporated in this section as if specifically set forth herein. (Code 2002, § 34-122. Ord. No. 10-1)
15.75.240 Structures subject to regulation.
(a) The provisions of this section shall not apply to any structure which is located within the designated floodway on the effective date of Ordinance No. 1181, September 8, 1980. However, an existing structure shall be deemed to be a nonconforming structure and shall conform to the provisions of this section if the structure is not used for a continuous six-month period or the structure is damaged or destroyed to the extent of more than 50 percent of its reasonable value. (b) The construction of structures in the designated floodway which may endanger life or significantly restrict the carrying capacity of the designated floodway shall be prohibited. (c) No structures shall be constructed within the areas of any temporary construction right-of-way established within the designated floodway. However, upon the completion of acceptance of floodway improvements, structures may be allowed in the area of the temporary construction right- of-way, provided there is no conflict with the provisions of this section and the Colby-Alquist Flood Plain Management Act.
(d) As used herein, “structures” does not include public utility electric, gas, or communication lines which may be located within the designated floodway.
(Code 2002, § 34-123. Ord. No. 10-1)
Article VI. Violations; Penalties.
15.75.250 Unlawful to violate chapter.
(a) It shall be unlawful for any person, firm, or corporation to construct, locate, extend, convert, or alter any structure or land without full compliance with the terms of this chapter and all other applicable regulations.
(b) Any person, firm, or corporation violating any of the provisions of this chapter shall be deemed guilty of an infraction and, upon conviction of any such violation, shall be punishable in accordance with section 1.05.220 of the Concord Municipal Code.
(Code 2002, § 34-141. Ord. No. 10-1)
Article VII. Variance Procedure
15.75.260 Nature of variances.
The issuance of a variance is for floodplain management purposes only. Insurance premium rates are determined by statute according to actuarial risk and will not be modified by the granting of a variance.
The variance criteria set forth in this section of the ordinance are based on the general principle of zoning law that variances pertain to a piece of property and are not personal in nature. A variance may be granted for a parcel of property with physical characteristics so unusual that complying with the requirements of this ordinance would create an exceptional hardship to the applicant or the surrounding property owners. The characteristics shall be unique to the property and not be shared by adjacent parcels. The unique characteristic shall pertain to the land itself, not to the structure, its inhabitants, or the property owners.
It is the duty of the city to help protect its citizens from flooding. This need is so compelling and the implications of the cost of insuring a structure built below flood level are so serious that variances from the flood elevation or from other requirements in the flood ordinance are quite rare. The long term goal of preventing and reducing flood loss and damage can only be met if variances are strictly limited. Therefore, the variance guidelines provided in this ordinance are more detailed and contain multiple provisions that shall be met before a variance can be properly granted. The criteria are designed to screen out those situations in which alternatives other than a variance are more appropriate.
(Code 2002, § 34-151. Ord. No. 10-1)
15.75.270 Conditions for variances.
(a) Generally, variances may be issued for new construction, substantial improvement, and other proposed new development to be erected on a lot of one half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing that the procedures of Articles IV and V of this chapter have been fully considered. As the lot size increases beyond one half acre, the technical justification required for issuing the variance increases. (ba) Variances may be issued for the repair or rehabilitation of “historic structures” (as defined in section 15.75.050 of this chapter) upon a determination that the proposed repair or rehabilitation will
not preclude the structure’s continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure. (cb) Variances shall not be issued within any mapped regulatory floodway if any increase in flood levels during the base flood discharge would result.
(dc) Variances shall only be issued upon a determination that the variance is the “minimum necessary” considering the flood hazard, to afford relief. “Minimum necessary” means to afford relief with a minimum of deviation from the requirements of this ordinance. For example, in the case of variances to an elevation requirement, this means the Floodplain Administrator need not grant permission for the applicant to build at grade, or even to whatever elevation the applicant proposes, but only to that elevation which the city believes will both provide relief and preserve the integrity of the local ordinance.
(ed) Any applicant to whom a variance is granted shall be given written notice over the signature of a community official that:
(1) The issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance up to amounts as high as $25 for $100 of insurance coverage, and
(2) Such construction below the base flood level increases risks to life and property. It is recommended that a copy of the notice shall be recorded by the Floodplain Administrator in the Office of the Contra Costa County Recorder and shall be recorded in a manner so that it appears in the chain of title of the affected parcel of land. (fe) The Floodplain Administrator will maintain a record of all variance actions, including justification for their issuance, and report such variances issued in its biennial report submitted to FEMA. (Code 2002, § 34-152. Ord. No. 10-1)
15.75.280 Denial of variance; appeal to City Council.
Denials of variances may be appealed to the City Council pursuant to section 2.05.050. (a) In hearing appeals for variances, the City Council shall consider all technical evaluations, all relevant factors, standards specified in other sections of this ordinance, and the:
(1) Danger that materials may be swept onto other lands to the injury of others; (2) Danger of life and property due to flooding or erosion damage; (3) Susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the existing individual owner and future owners of the property; (4) Importance of the services provided by the proposed facility to the community; (5) Necessity to the facility of a waterfront location, where applicable;
(6) Availability of alternative locations for the proposed use which are not subject to flooding or erosion damage;
(7) Compatibility of the proposed use with existing and anticipated development; (8) Relationship of the proposed use to the comprehensive plan and floodplain management program for that area;
(9) Safety of access to the property in time of flood for ordinary and emergency vehicles; (10) Expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters expected at the site; and
(11) Costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water system, and streets and bridges.
(b) Variances shall only be issued upon a:
(1) Showing of good and sufficient cause;
(2) Determination that failure to grant the variance would result in exceptional “hardship” (section 15.75.050) to the applicant; and
(3) Determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, or extraordinary public expense, create a nuisance (see “Public safety and nuisance” section 15.75.050), cause “fraud and victimization” (section 15.75.050) of the public, or conflict with existing local laws or ordinances. (c) Variances may be issued for new construction, substantial improvement, and other proposed new development necessary for the conduct of a functionally dependent use provided that the provisions of subsections 15.75.280(a) through 15.75.280(d) are satisfied and that the structure or other development is protected by methods that minimize flood damages during the base flood and does not result in additional threats to public safety and does not create a public nuisance. (d) Upon consideration of the factors of subsection 15.75.270(a) and the purposes of this ordinance, the City Council may attach such conditions to the granting of variances as it deems necessary to further the purposes of this ordinance.
(Code 2002, § 34-153. Ord. No. 10-1)
Article VIII. Other Measures
15.75.290 Hazard mitigation plan and evacuation plan.
The city shall consider the following when reviewing floodplain development applications:
(a) Hazard mitigation plan. The city shall weigh all requests for future floodplain development against the city’s General Plan. Consideration of the following elements is required before approval:
(1) Determination of whether or not a proposed development is in, or affects, a known floodplain;
(2) Determine if there is a practicable alternative or site for the proposed activity; (3) Identify impact of the activity on the floodplain;
(4) Provide a plan to mitigate the impact of the activity. (b) Evacuation plan. There is on file, with the city’s Director of Emergency Services, an evacuation plan, alternate vehicular access and escape route for the benefit of the residents of manufactured home parks and manufactured home subdivisions which are located within zone A of the map identified in section 15.75.070 above.
