The Legislature of the State of California has in Government Code Sections 65302, 65560, and 65800 conferred upon local government units authority to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. 15.24.020 Findings of fact. A. The flood hazard areas of the City are subject to periodic inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of whjch adversely affect the public health, safety and general welfare. B. These flood losses are caused by the cumulative effect of obstructions in areas of special flood hazards which increase flood heights and velocities, and when inadequately anchored, damage uses in other areas. Uses that are inadequately floodproofed, elevated or otherwise protected from flood damage also contribute to the flood loss. 15.24.030 Statement of purpose. It is the purpose of this Chapter to promote the public health, safety, and general welfare, and to minimize public and private losses due to flood conditions in specific areas by provisions designed: A. To protect human life and health; B. To minimize expenditure of public money for costly flood -control projects; C. To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; D. To minimize prolonged business interruptions; E. To minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in areas of special flood hazard; ' F. To help maintain a stable tax base by providing for the second use and development of areas of special flood hazard so as to;minimize future flood blight areas; G. To insure that potential buyers are notified that property is in an area of special flood hazard; and H. To insure that those who occupy the areas of special flood hazard assume responsibility for their actions. 15.24.040 Methods of reducing flood losses. In order to accomplish its purposes, this Chapter includes methods and provisions for: A. Restricting or prohibiting uses which are dangerous to health, safety, and property due to water or erosinn hazards, or which result in damaging increases in erosion or flood heights or velocities; B. Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; C. Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel flood waters; D. Controlling filling, grading, dredging, and other development which may increase flood damage; and E. Preventing or regulating the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards in other areas. II.

Tris Chapter shall apply to all areas of special flood hazards and areas of mudslide (i.e., mudflow) hazards within the jurisciction of the City. 15.24.070 Basis for establishing the areas cf special flood hazard. The areas of special flood hazards and areas of mudslide (i.e., mudflow) hazards identified by the Federal Emergency Management Agency or the Federal Insurance Adminstration in a scientific and engineering report entitled "Flood Insurance Study for the City of Beaumont", dated October 17, 1978, with an -5- accompanying Flood Insurance Rate Map is hereby adopted by reference and declared to be a part of this Chapter. This Flood Insurance Study is on file at the Building Department, City of Beaumont, 550 East 6th Street, Beaumont, California 92223. This Flood Insurance Study is supplemented by studies for other areas which allow implementation of this Chapter and which are recommended to the City Council by the Building Director. 15.24.080 Compliance. No structure or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of this Chapter and other applicable regulations. Violations of the provisions of this Chapter by failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with conditions) shall constitute a misdemeanor.

Review all Development Permits to determine that the permit requirements of this Chapter have been sati=sfied; 2. All other required State and Federal ;hermits have been obtained; 3. The site is reasonably safe from flooding; and 4. The proposed development does not adversely affect the carrying capacity of the areas where base flood elevations have been determined but a floodway has not been designated. For purposes of this Chapter, "adversely affects" means that the cumulative effect of the proposed development when combined with all other existing and anticipated developments will not increase the water surface elevation of the base flood more than one (1) foot at any point. B. Use of Other Base Flood Data. When base flood elevation data has not been provided in accordance with Section 15.24.070, the Building Inspector shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a Federal, State or other source, in order to administer Sections 15.24.170 through 15.24.250. Any such information shall be submitted to the City Council for adoption. C. Whenever a watercourse is to be altered or relocated: 1. Notify adjacent communities and the California Department of Water Resources prior to such alteration or relocation of a watercouse, and submit evidence of such notification to the Federal Insurance Administration; 2. Require that the flood carrying capacity of the altered or relocated portion of said watercourse is maintained. D. Obtain and maintain for public inspection and make available as needed: 1. The certification required in Section. 15.24.200.A (floor elevations); 2. The certification required in Section. 15.24.200.B (elevations in areas of shallow flooding); 3. The certification required in Section 15.24.200.0 (elevation or floodproofing of nonresidential structions); 4.

Make interpretations where needed, as to the exact location of the boundaries of the areas of special flood hazards or areas of mudslide (i.e., mudflow) (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in Sections 15.24.150 and 15.24.160. F. Take action to remedy violations of this Chapter as specified in Section 15.24.080 herein. IV. VARIANCE PROCEDURE 15.24.150 Appeal board. A. The City Council shall hear and decide appeals and requests for variances from the requirements of th:Ls Chapter. B. The City Council shall hear and decide appeals when it is alleged there is an error in any requirement, dQcision, or determination made by the Building Inspector in thou? enforcement or administration of this Chapter. C. In passing upon such applications, the Ci:y Council shall consider all technical evaluations, all rele',ant factors, standards specified in other Sections of this Chapter, and: 1. The danger that materials may be swep: onto other lands to the injury of . others; 2. The danger to life and property due tp flooding or erosion damage; 3. The susceptibility of the proposed fa;ility and its contents to flood damage and the effect of such danage on the individual owner; 4. The importance of the services provided by the proposed facility to the community; 5. The necessity to the facility of a waterfront location, where applicable; 6.

The safety of access to the property in time of flood for ordinary and emergency vehicles; 10. The expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters expected at the site; and 11. The 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. D. Generally, variances may be issued for new construction and substantial improvements 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 subdivisions 1 through 11 of subsection C of this Section have been fully considered. As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases. E. Upon consideration of the factors of subsection C of this Section and the purposes of this Chapter, the City Council may attach such conditions to the granting of variances as it deems necessary to further the purposes of this Chapter. F. The Building Department shall maintain the records of all appeal actions and report any variances to the Federal Insurance Administration upon request. 15.24.160 Conditions for variances. A. Variances may be issued for the reconstruction, rehabilitation or restoration of structures listed in the National Register of Historic Places or the State Inventory of Historic Places, without regard to the procedures set forth in the remainder of this Section. B. Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. C. Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. D. Variances shall only be issued upon: 1. A showing of good and sufficient cause; 2. A determination that failure to grant the variance would result in exceptional hardship to the applicant; and 3. A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, -8- cause fraud on or victimization of the public, or conflict with existing local laws or ordinances. E. Variances may be issued for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that the provisions of subsections A through D of this Section are satisfied and that the structure or other developm.nt is protected by methods that minimize flood damages daring the base flood and create no additional threats to public safety. F. Any applicant to whom a variance is grantad shall be given written notice that the structure will be permitted to be built with a lowest floor elevation below the regulatory flood elevation and that the cost of flood insurance will be commensurate with the increased risk resulting fron the reduced lowest floor elevation. A copy of the notice shall be recorded by the Floodplain Board in the office of the Riverside County Recorder and shall be recorded in a manner so that it appears in the chain of title of the affected parcel of land.
