City ofForl Collins Hazard Mitigation 404 Grant Application The April 30, 1999 event, other stonn events, past, and future storm drainage master planning are useful in identifying areas subject to shallow flooding_ The City currently offers a floodplain infonnation service that gives the public information on both FEMA and City designated floodplains_ The City also currently offers staff site visits to help answer homeowner's questions and give technical guidance. In the future it may be possible to include floodproofing information in the City's GIS database. The City can then alert the applicant to the potential need for floodproofing during review of building pennit applications. The project is expected to be completed 2 years from the date of the disaster declaration, which is May 17,2001. D. Floodproofing as a Mitigation Alternative - Hazard Reduction The specific causes of shallow flooding of buildings in ,Fort Collins that were identified above all have to do with drainage conveyance. One kind of mitigation strategies would be based on improving flow conveyance, whether it be in streets, storm sewers or channels_ The Fort Collins Utilities already has a long history of such conveyance projects_ Such a strategy will be considered as an alternative for addressing shallow flooding of buildings_ In some instances in Fort Collins, however, it is most practical and cost effective to floodproof existing floodproof structures. ~ Floodproofing includes any effort property owners may take to reduce flood damage to buildings and their contents. According to the US Army Corps of Engineers publication, Flood Proofing, How to Evaluate Your Options, "Floodproofing may be designed to either reduce the nwnber of times the building is flooded or limit the potential damage to the building and its contents when it is flooded. There are three general approaches to floodproofing: . Raising or moving the building . Constructing floodwalls or levees to stop floodwaters from entering the building . Modifying the building and relocating contents to minimize flood damage_" Generally, floodproofing is most cost effective where flooding is shallow (less than three feet deep} Most flood damage occurring in Fort Collins on a regular basis is due to shallow flooding. The Old Town Master Drainage Basin Plan (1993) identified areas where significant flows and depths of floodwater will occur, and typically the 100-year flooding will be less than 1.5 feet in depth. Those areas where flooding periodically is greater than three feet have generally either been demolished or relocated due to the frequency of flood events in Fort Collins. New construction must adhere to current drainage criteria which precludes or greatly restricts development in flood hazard areas. 19
