... a Class 4 Rating, consistent with Fort Collins, the annual savings could exceed $120,000 (offsetting staff costs in community benefits). In addition, affordable policies could encourage greater flood insurance purchases and this would produce increased premium savings. c) Implement a Comprehensive Internet Web Site for floodplain information and e-business. With the high level ofInternet access and usage in Boulder this tool could provide direct public access to important floodplain information, such as floodplain maps, letters of map revision, flood insurance information and a record of elevation certificates for buildings. Staffwill be releasing an interactive floodplain map in the near future that will allow a citizen to search fora specific address to be shown on the GIS-based floodplain map over the Internet. The web site may also provide valuable links to other floodplain agencies such as FEMA. d) Create a Flood Proofing Program to help citizens protect their property through onsite staff consultation, the provision of self-help information and possible low-interest loan programs to construct flood proofing. 4. "Prevent Adverse Impacts and Unwise Uses in the Floodplain" through appropriate regulation and land zoning, open land preservation and acquisition, multi-objective planning, acquisition and relocation of high hazard structures, and prohibiting unacceptable encroachments. Tools for Implementation: a) Consider Recommended Floodplain Regulation Revisions that include: · Maintaining the current high hazard zone standards prohibiting new structures intended for human occupancy. · SOO-year protection for critical facilities (consistent with development of the new Boulder Community Hospital and Foothills Housing development). Critical facilities would include among others publicly owned buildings, hospitals, managed care facilities and schools. · Prohibiting adverse floodplain encroachments and impacts that would increase flood depths (consistent with the conveyance zone restrictions) or velocities, or reduce flood storage, to maintain the current canying capacity of the floodplain, prevent creating high hazard conditions or increasing downstream flooding. · Requiring safe emergency access routes to buildings during floods and ensuring that functional emergency exits during flooding are provided from flood proofed buildings. · Requiring multiple storm level protection measures to account for flooding from storms greater than 100-year magnitude · Lowering zoning densities in floodplains and offering possible transfer of development rights to avoid new floodplain encroachments · Adopting a floodplain buffer to address mapping uncertainties and avoid future flood impacts. b) Consider Guiding Principals to apply to floodplain mitigation planning that support multiple objectives, community goals and public involvement. Such guiding principals are emerging from IRP and CAG efforts on the Fourmile Canyon Creek and South Boulder Creek master plan studies. c) Expand Property Acquisition and Urban Open Lands Preservation activities for the most hazardous floodplain areas and areas with beneficial floodplain functions. Such acquisition applications would be for non- structural floodplain management and would not involve land purchases for structural mitigation (such as excavating channels). d) Enhance Storm Water Management Activities to ensure ongoing monitoring and maintenance of drainage systems and flood areas by clarifying specific maintenance practices for designated locations to ensure that Open Space and open lands preserving floodplains are maintained differently from improved drainage facilities. 5. "Seek to Accommodate Floods. Not Control Them" through planned and monitored system maintenance, nonstructural flood proofing, opening non-containment corridors, overbank land shaping to train flood waters, and limited structural (channelization) measures at constrained locations.
