  10. FEDERAL PROCESS CHANGESS Emerging Urban Flood Management Policy Changes • Simplify the paper work process • paperwork and process for mitigation grants is excessive, and a huge time burden for local communities • Streamline the Post Disaster Hazard Mitigation Process for buyout properties • takes a long period of time before real assistance is available, and often leaves property owners with very few options at a time when they need immediate assistance • Allow local program expenditures to be reimbursed if FEMA guidelines are followed. • local match is difficult to budget for, allow some form of repayment

  11. FEDERAL PROCESS CHANGESS Emerging Urban Flood Management Policy Changes • Pre-flood mitigation programs are preferable, and more are needed • Encourage watershed-wide approach to flood management, and allow regulation to be imposed that causes development to consider and mitigate the downstream impact • A means to offset the local impact of purchase/maintenance of City-owned flood plain • As more and more property is bought out and deed restricted and returned to the flood plain, it adds more and more property that a city owns and must maintain, while further reducing taxable property values.
