Properties in the Poudre River floodplain in the City of Fort Collins are subject to different regulations than those located in Larimer County. City and County staffs have developed recommendations that would address most of the problems created by the different regulations. Public outreach was performed during the formulation of the regulation changes which included notices to owners of properties in the floodplain in both the City and the County about an open house,presentations to special interest groups,review by City and County boards and commissions and information posted on the City's 7eb page. City C ut�,i disfussed this item at its December 12, 2006 work session. t!, 9ji X �EI' BACKGROUND Floodplain regulations were first adopted in the City in the mid 1970's for the Poudre River. The City of Fort Collins entered the National Flood Insurance Program in 1979 with the adoption of floodplain regulations for the Poudre River, Spring Creek, and Dry Creek basins. Undeveloped properties located in a floodplain can develop as long as they comply with the floodplain regulations. January 16, 2007 -2- Item No. 28 Properties in the Poudre River floodplain in the City of Fort Collins are subject to different regulations than those located in Larimer County. This creates numerous problems during development and annexation processes. The approved East Mulberry Corridor Plan directed City and County staffs to review the f�,eudr�, R},w,flpodglei reg latiops to make them as consistent as possible. Floodplain Maps and Property Statlsti A map of the Poudre River floodplain within the City's Growth Management Area is Attachment 1. The 100-year 0.5-foot floodway(areas of greatest risk with high depths and velocities)are shown in dark blue. The 0.1-foot floodway is shown in the yellow outside of the 0.5-foot floodway. The Product Corridor is delineated by a red line. The 100-year flood fringe is shown in light blue. The moderate risk areas,shown in green,are either the existing Federal Emergency Management Agency (FEMA)500-year floodplains or areas of sheet flow in the 100-year floodplain with less than 1-foot of depth. Attachment 2 shows this same information with properties in public ownership highlighted. Attachment 3 is a table showing a detailed summary of the areas in the floodplain comparing private and public ownership and the various floodway configurations. The table and maps illustrate that there is a great deal of public land in the floodplain and the regulation changes affect a relatively small amount of developable 1 p �sery ng is,: arg amount of land through public open space, Fort Collins has providq�a hig�� vel o o p tec pu,because of the limited amount of development subject to floodirl Proposed Floodplain Regulation Changes Staffs from both the City and County compared their respective regulations. There were eight areas of disagreement between the City and County regulations identified as a part of this project. Keeping in mind there are some areas where both the City would become less restrictive and the County would become more restrictive, the recommended changes include five areas where the City's regulations would become less restrictive, four areas where the County's regulations would become more restrictive, and one area where City and County staffs could not reach agreement, resulting in an ongoing difference in regulation. Attachment 4 is a summary table listing the proposed changes for both the City and County. These recommendations represent a negotiated compromise while still balancing risk with regulation. The importance of protecting and enhancing the natural features and functions of the river were also considered. Attachment 5, "Pre se4 FI pdpl in- egtl�atijt s fb�pthe Poudre River Quick Guide„ was prepared to help illustratero d re at nsP111' III Of the five areas where City stalm»is•reco t�mity regwl�tions be made less restrictive, two are proposed to be totally eliminated because they do not balance risk with regulation and are ineffective or are technically difficult to administer. Details of the proposed changes and the sections of City Code to be modified are as follows. January 16, 2007 -3- Item No. 28 Changes to Align City-County Regulations Floodway Definition ,a'Syl�i '�fI 'rats Current City Code defines th I oodwa for t�P d iuRi a rise of 0.1-foot. The current County floodway rise definiti is 0.5-f t. Tent offic FEMA floodway is based on a 1- pj foot rise definition. It is propos nthwcitj wort d c ge its flobdway to the County's 0.5-foot rise definition. • Section 10-16 Definitions—Floodway Floodway Modification Current City Code states that only the City can modify the floodway for public infrastructure or publicly owned recreation facilities as long as there is a no-rise condition, channel stability is maintained and the natural environment along the river is either protected or enhanced. Current County regulations state that floodway modification is allowed byboth the public and private sectors as long as the no-rise criterion is met. It is proposed the County would add the channel stability and environmental considerations criteria. The City would not change its criteria except to allow floodway modification by both public and private entities. • Section 10-27(d)�,5r)°Srtgbil'Aty°aq#,lys '11 • Section 10-45 F 6dway odifi tti �f • Section 10-71( Flood mc, c ion • Section 10-72(2, 14„and 5 fFillryrE .• 11h.. �.. • Section 10-80(a)(1) LOMR/PMR Critical Facilities in the 100-year Floodplain Critical facilities are made up of three categories: life safety, emergency response and hazardous materials. The County does not have regulations pertaining to critical facilities in the 100-year floodplain. The City has regulations prohibiting critical facilities in the 100-year floodplain. It is proposed the County add the provision that life safety and emergency response critical facilities not be allowed in the 100-year floodplain. However, City and County staff have not reached an agreement on the hazardous materials criteria. City staff believes that it should be included and County staff is hesitant to include the provision due to the anticipated large number of parcels with hazardous materials in the Airpark area. At the work session some members of Council encouraged the County to adopt the City standard for hazardous materials. City staff recommends the City Code not be changed regarding this issue. MTh r,yresutt m y l� that, City and County regulations do not agree on this issue. ,CII' i,' Critical Facilities in the 500-Ye�r,Flo6dnihinr, I - 11 Current City Code does not allow critical facilities, including life safety, emergency response, and hazardous materials facilities in the 500-year floodplain. The County does not regulate critical facilities in the 500-year floodplain. The County would begin regulating life safety and emergency response critical facilities in the 500-year floodplain. The City would continue to regulate life safety and emergency response critical facilities but would allow hazardous material critical facilities in the 500-year floodplain. January 16, 2007 -4- Item No. 28 • Section 10-81 Specific standards for Poudre River five-hundred-year floodplain and zone X shaded areas Freeboard Level The current freeboard requirem�etkt,iaaAhe burnt is-Ili-inches. a City's requirement is 24-inches. It is proposed the County will change the freeboard requirement to 24-inches consistent with the City's. Letter of Map Revision (LOMR)-Fill Requirements Currently FEMA requires local governments to sign off on LOMR-Fill applications stating that structures are safe from flooding when structures are removed from the floodplain through the LOMR-Fill process. Currently the City has a provision requiring that structures must be elevated 24-inches above the flood elevation and not allowing critical facilities in LOMR-Fill areas. The County currently doesn't have these provisions. It is proposed the County would add the 24-inch freeboard and the no new critical facilities criteria in LOMR-Fill areas. Changes to Balance Risk with Regulation and Remove Ineffective Provisions (Also Aligns City-County Regut#,ti ) ,,,, ,,,{;,, ,,. Product Corridor �� ; Current City Code defines the Product Corridor using 500-year discharges as an area when the velocity times the depth is six. No encroachment and no variances are allowed in the Product Corridor. Staff has found this regulation to be excessive,not allowing for special circumstances and technically impractical to administer due to difficulty in making accurate determinations. The product corridor is also a redundant layer of regulation, since the area in the 500-year product corridor is substantially the same as the 100-year floodway. Currently the County does not have a product corridor regulation. It is proposed the City would remove from the Code the provisions or references pertaining to the Product Corridor. • Section 10-16 Definitions - Product Corridor • Section 10-16 Definitions—Floodway modification • Section 10-19 Flood hazard area designation • Section 10-27(a) Floodplain use permit • Section 10-27(c)4�)Flpod i 1, se t vjl Section 10-27( 3) Floo�lain a I� • Section 10-29(fNHConditi s for 'ces S,, • Section 10-42(a)"Specific standards Ibr recreatitlnal vehicles Section 10-45 Floodway evaluations • Section 10-45(b) Floodway evaluations • Section 10-71 Specific standards for development in Poudre River floodway • Section 10-71(8) Floodway modification • Section 10-72 Specific standards for nonstructural development in Poudre River floodway • Section 10-72(4) Fill January 16, 2007 -5- Item No. 28 • Section 10-73 Floodway encroachments in Poudre River floodway • Section 10-74 Change of use in Poudre River floodway • Section 10-201 Designation of erosion buffer zones Dryland Access „i! GG) ,r• Current City Code states that n6v.develo merit must have dr}aaccess to any new structure. Staff has found that often times offsite roads leading to a property are underwater making the requirement irrelevant and variances are often granted. Current County regulations do not have a dryland access regulation. It is proposed that the City remove from the Code the provisions or references pertaining to the dryland access. Section 10-16 Definitions—Dryland access • Section 10-71(10)Dryland access Section 10-75(9) Dryland access • Section 10-76(9) Dryland access • Section 10-77(9) Dryland access Section 10-80(a)(2) LOMR-F Housekeeping Changes There are some minor "house eping4', iems t e it(clu dAn the proposed changes. These changes are needed to make thql ontext the Ce guage c sistent throughout. The definition for redevelopment was change' +1ato xri it ¢nnsi el with., a definition that applies to other floodplains citywide. The LOMR-Fill section was reworded to make it consistent as well. Changes to the code have also been made to include reference to FEMA's Physical Map Revision (PMR) process. Community Rating System and Flood Insurance Considerations All structures in Fort Collins are eligible for flood insurance regardless of whether they are located in a floodplain or not. The cost of flood insurance depends on many variables including amount of coverage,deductibles,type of structure,and how high the structure is elevated above the flood level. The FEMA Community Rating System (CRS) is a voluntary incentive program that encourages communities to go beyond FEMA minimum requirements for floodplain management. Based on a rating of numerous stormwater management activities (public outreach, higher regulatory standards, drainage system mai enauge, ood„E am' re rvat�;on of open space, etc.)residents and businesses of a communit G eceive isco t t�r flId insurance premiums. The City of Fort Collins currentlyhas one high CR at gs m the tion,providing our customers with a 30% discount on flood insurance'j remiun . .•,It• is anticioated the changes included in the Ordinance would not change the City's CRS rating. None of the proposed changes are below FEMA minimum standards. Public Outreach A variety of communication tools such as floodplain property owner customer notices, information on the City's web page, a press release, public meetings and open houses, and outreach to both January 16, 2007 -6- Item No. 28 internal and external groups potentially affected were used. Presentations were made to four City Boards and Commissions and to City Council at a work session to solicit comments and recommendations. A joint City and County open house was held to solicit comments from the public on the proposed change �,t::M� ti s-W re p& el4 1th!0e Mulberry Corridor Owner's Association and the Chamber' cal�islah ai�Cittee. The County held meetings with County boards and comn�sions a ell �I, E hi 41 Gil; 91 The City of Fort Collins Following is a summary of discussion of the various boards and commissions. Excerpts of the minutes from the Water Board, Land Conservation and Stewardship Board and Natural Resources Advisory Board are included as Attachment 6. There are no minutes available from the Planning and Zoning Board because they discussed this item at a study session. The Water Board formally passed a motion (7-2) in support of the proposed changes with Alternative 2, to not allow hazardous materials critical facilities in the 100-year floodplain. Two members did not support the motion because they felt the City shouldn't lower any of its regulations for the Poudre River. The Planning and Zoning Board discussed this item at a study session and it was the consensus of the members present to support Jhegfop aed e an as, itl411 ltemative 2, to not allow hazardous materials critical facilities in�e 100-'y,Q�r flo pl n.i,�ne ethber did not voice their opinion because they felt they did not ve enou info a on to exp ss an opinion. The Land Conservation and Stewardship Board did not act on the proposed changes as a whole. They supported staff's minimum recommendation to remove the product corridor and dryland access regulations. They also supported staff s proposal to add stability and environmental factors to the County's floodway modification regulations.Finally,they recommended Council adopt Alternative 2, to not allow hazardous material critical facilities in the 100-year floodplain. The Board did not take action on the other staff recommendations because they felt it was not under their area of expertise to offer a recommendation. The Natural Resources Advisory Board discussed this item at two of its meetings and formally passed a motion unanimously in support of Alternative 2, the regulation of hazardous materials in the 100-year floodplain due to concerns about the environmental impacts of hazardous materials in flood waters. The Board chose not to take a position on the other recommended changes. On December 12, 2006 City Council held two senl i�a onghe pupposed regulation revisions(see Attachment 7). The following, ey disc ' lion p i w�e r� ell' • Development of the recormaaende '�chatiges•�as done.•l the spirit of compromise of trying to bring the City and County regulations closer together. January 16, 2007 -7. Item No. 28 • The approach to balancing risk with regulation for the floodplain regulations seemed reasonable to protect people and property, however, it was also pointed out that floodplain regulations also protect the natural beneficial functions of the river. • The proposed changes w' l allq�v l ye, alogg the river corridor,but will also have some environme '1 ben ef m e nheeacorridor as well. • One member of Counci aised a nee el ity was g ng lower to the County level,when the County should be go ing„,to"the"�itYn le I.of flood ,lain regulation. • A majority of the Council supported the staff recommendation; however, concerns were expressed regarding the elimination of the product corridor regulations and going from a 0.1- foot floodway to a 0.5-foot floodway. Larimer County The Board of County Commissioners and County Planning Commission held a work session on November 8, 2006 to discuss the proposed changes. County staff presented history and salient points of the proposed changes to the floodplain regulations. Clarification was made that on a lot with an existing structure, any new structure would need to be 24-inches above the flood elevation or an increase of 6-inches over the current regulations. The question was raised if the proposed requirements for floodway modification would prevent "channelization" or narrowing of the floodway and staff responded that the language regarding stability was intended to do just that, although additional language rsta'�f,' t a prop at JET eft was made given the degree of effort that has been expended t y wo Jd l se li;,ho effort move forward in a timely manner if possible. 41! The County Planning Commission is scheduled to consider this item on January 17, 2007. The Board of County Commissioners is scheduled to consider this item on January 22,2007. Any adjustments to the City's proposed changes resulting from the County Commissioner's action on January 22, 2007 will be made between the City's First and Second Reading. Other Outreach A joint open house for both the City and County was held on November 14th at the Lincoln Center. Approximately 3,500 notices were mailed to city and countyproperty owners in the floodplain along with a press release in the newspaper advertising the open house. Approximately 55 property owners attended the open house. At the open house comment sheets were available to solicit comments from those attending the open house. Three comment sheets were returned requesting copies of the open house materi sand on •stag th ,m a 'me,ishould be directed toward flood control projects. One citizens ed verb ' y tha eXtid' pti floatable material should be less restrictive. Other verbal cots rece pd by a�Were ove�l in favor of the proposed changes. On December 12, 2006 City and County staff presented the proposed revisions to the Mulberry Corridor Owner's Association. A few clarification questions were raised and no adverse comments were received. On December 1, 2006 City staff presented the proposed revisions to the Chamber of Commerce Local Legislative Affairs Committee. During the discussion questions were answered clarifying the proposed changes with comments overall in favor of the recommendations. January 16, 2007 -8- Item No. 28 ATTACHMENTS 1.
