Flood Plan Policy Report 1974 • Vera • • FLOOD PLAIN POLICY 'REPORT February 19 , 1974 • This report is intended to serve as a guide to- the Planning Commission in making a determination of whether or not to recommend to the appropriate governing body participation in either the Flood Insurance Program or Flood Plain Zoning. The Planning Commission has already done the following: April: 24 , 1973 - Special meeting of the Planning Commission - A motion approved recommending denial of the flood plain concept as a part of the Land Use Plan. - dA motion approved recommending that the general concept of flood plains be written down with a warning about the flood plain area and giving-non- . mandatory elevations as guidelines. - , A motion approved that residential development shall not be encouraged to occur in areas subject to flooding. May' 10 , 1973 - Meeting with the Corps of Engineers and . • Kansas Board of Water Resources . ,• Explanation of the Flood Insurance Program of 1968 . May 22; ±973 ,- Special meeting of the Planning Commission Attion"approved that the Planning Commission accept the recommendation of Oblinger and Smith, : whereby the .Planning Commission will direct Oblinger and .Smith to draw up flood plain zoning regulations in accordance with their recommendation that two zoned_ be. adopted : (1) Floodway (2) Fringe Area of the Floodway January 14 , 1974 - Meeting with the Corps of Engineers and Kansas Board of Water Resources . • More detailed information concerning amount of development permitted in the flood plain (encroachment study) . • Brief explanation of implication of new federal legislation (Flood .Disaster Protection Act -of 1973) . In summary then, the status of flood plain zoning is that two (2) zones will be included in the proposed zoning ordinance now being proposedby Oblinger-Smith and a decision was made not to include the flood plain concept in the proposed Land Use - Plan. No firm decision has been reached regarding Salina ' s participation in the Liood Insurance Program. . A brief summary of the new legislation follows. - 1 - 4 • Flood Disaster Protection Act of 1'973 A Summary The Flood Disaster Protection Act of 1973 (P.L. 93-234) , which was signed into law by the President on December 31, 1973 , • significantly expands the availability of flood insurance and will force from 10, 000 to 12 , 000 flood-prone communities into measures designed to minimize their flood hazard or be faced with the loss of federal assistance. Salina is one of these communities . A-White House statement, . released as the law was signed, said that the Act "will call upon owners of property in flood-prone areas to purchase flood insurance if they are to benefit from financial assistance for their property from the federal government or from any federally-insured, regulated, or supervised lending institution. It will also encourage forward-looking officials to adopt and to enforce adequate and appropriate land use and other control .measures to reduce the probability of losses resulting from floods. " ' The program establishes several significant dates : July 1, 1974 HUD Must identify flood-prone communities and notify their chief executive officers . - • January 1 , 1975- - date to prove that a community is not flood prone or to apply for participation. July 1, 1975 - federal money is to longer available to businesses and individuals for construction or purchase purposes (incl. FDIC, FSLIC, FHA, etc. ) , unless the community has qualified for the program. (See attached timetable for more detailed breakdown) In order to qualify for the Flood Insurance Program, communities must adopt, or have in effect, a building permit system which allows for review of new construction to guard against obvious , locally-known flood hazards. It will probably be advisable for each community to initiate some sort of flood plain zoning in order to effectively complement the permit system. Some of the other features of the law are : • - Structures in existence or started before the area was identified as hazardous are not required to have insurance. - The subsidized coverage limit for residential buildings is $35, 000 for single. family residences -and $100 , 000 for others . - 2 - • - Consultation with local officials when determining flood-prone areas and the application of land manage- ment criteria . - Both individuals and communities have a period during which they may appeal HOD ' s determinations . As should be apparent, any attempt at control of flood plains will necessitate detailed engineering- studies (see attached report from Engineering Department) in order to accurately determine the limits of flood-prohibited construction .and the extent of -restrictions to be placed on construction occuring within buildable areas . Without it, no realistic "elevation guidelines" can be determined. Therefore, in order to effectively comply with the previous intentions of the Planning Commission and warn developers and builders of a flood hazard by giving these elevation guidelines , active participation in .the Flood Insurance Program should be encouraged . It is the recommendation of the Planning Department staff that this course of action be vigorously pursued. • • • 3 - • . • Timetable for Participation in Flood Insurance Program • fHUD identifies community as flood prone. (All such communities are to 1 be identified within 6 months after enactment of the legislation . ) I The community applies for eligibility. Application includes proof of a building permit system in force which allows reviece of new construction to guard against obvious , locally-known flood hazards. • . . 0 'IUD approves application. Subsidized flood insurance becomes " available . for existing structures and new construction regardless of location - in community. (An equal amount of unsubsidized insurance will not be available until after completion of a time-consuming actuarial study. ) (HUD identifies special flood hazard areas within the community (usually within 3 to 6 monthsaatter community applies for eligibility) . 0 New construction within special flood hazard areas is no longer eligible for subsidized insurance, but must wait for completion of actuarial studies to determine insurance rates . The community 's flood hazard ordinances must take precedence over all other laws and ordinances within special flood hazard areas. • THUD provides water surface elevations for the community ' s 100-year flood and makes available the results of the actuarial study (usually 1 to 2 years after community enters the program) . Within 6 months, the community must require all residential new construction or substantial improvements (50 percent or more of cash value) to have lowest floor, including basement, elevated to or above the 100-year flood level. For nonresidential construction there is an option of either elevation or floodproofing. In riverine situations, any use •must be prohibited that will increase water surface elevation more than 1 foot : at' any point .. Flood insurance- is made available at actuarial rates • to new construction in flood hazard areas (also available to all others . in community) . No -federal financial assistance or federally related assistance is available for new acquisition or- construction projects in special flood hazard areas unless fully covered by available insurance . • THUD provides floodway data for specific community. 1 Community has 6 months to (1) designate floodway for passage of water of 100-year flood so as not to increase water surface elevation more than 1 foot , (2) prohibit expansion of non-conforming uses in floodway, and (3) prohibit fill or encroachments in floodway that would impair its ability to carry or discharge water. • - 4 - . • • • • • FLOOD PLAIN MANAGEMENT - Engineering Department Report RE : Petition No. 3332 - J. Barton Webster P . I .P . Development - The Lee Hardware Company It would appear to be an impossible task for the City Engineering Staff to establish elevations for flood plains at this time . To establish these elevations requires a detailed hydrologic study of the entire drainage area . These elevations then become: ve- ry • critical in establishing the areas to which flood plain zoning would apply. These elevations would define the boundary between the area of the flood plain which could be encroached upon • under certain conditions and the area of the flood plain which • must be designated as a floodway and prohibiting any development that would inhibit the flow of flood waters in any manner. The above referenced developments are both in an area that would be part of the Dry Creek Flood Plain. Any attempt to state an elevation at• this time to which they should build their development would be a hazardous guess at best. Any valid study which would define areas and elevations for flood plain zoning would have to include the entire potential flood plain area-. Any infringement • on the flood plain in one area would have to be compatible with an infringement which could be allowed in another area. • For the City to attempt to establish flood plains and flood elevations on our own would probably cost around $250 , 000 .00 and take approximately a years time. In addition, I do not know what liability the City may incur_. from such action. • • • - 5 -
