Flooding History

Red River of the North, 1897 Mississippi River Headwaters at Itasca State Park

City of Rushford, 2007

City of Minneapolis 2014 Oslo, 2019

Between 1957 and 2018, there have been 49 flood-related presidential disaster declarations in Minnesota. Nineteen of those have occurred since 2004.

help make flood risk reduction locally affordable.

  • Established by the Minnesota Legislature in 1987 to help make

flood risk reduction locally affordable.

  • Provides state cost share funding to local

units of government to plan and implement a host of measures that reduce flood risk to public and private improvements.

  • Established by the Minnesota Legislature in 1987 to help

make flood risk reduction locally affordable.

  • Provides state cost share funding to local units of government

to plan and implement a host of measure that reduce flood risk to public and private improvements.

  • Eligible projects include acquisition and

removal of flood prone structures, levees, diversions, floodwalls, pumping stations, impoundments, flood mapping, warning systems, etc.

  • Flexibility & allocation discretion ensure the

funds are directed to those at greatest risk, and ready to act.

  • Projects are locally grown, locally managed.
  • Partnerships = possibilities, key to program

success

The program works because….

  • Facilitated by the Minnesota Department of

Public Safety – Division of Homeland Security & Emergency Management

  • ad hoc group of federal, state and local agencies

working together to efficiently and effectively coordinate disaster recovery.

Minnesota Funding for Flood Hazard Mitigation 1988 - 2018

$544 million in state funding since 1988, in addition to close to $700 million in federal and local matching funds Historic 1997 Red River flood

Enabling legislation requires an equal non-state match from grantee

Local match can be in form of in-kind contribution, federal or other local funds, private donations, local option sales tax, assessment to benefitted properties. Cannot match state funds with state funds.

Rider language in the past several appropriation bills has limited the local share for municipalities, making flood mitigation a reality in many places that otherwise could not afford it.

Mitigation Successes So... what have we accomplished since 1987?

slide-24
SLIDE 24

Mitigation Successes

  • Acquisition and removal of at-risk structures
  • Levees
  • Diversions
  • Floodwalls
  • Flood and multi-purpose impoundments
  • Structural flood proofing
  • Ecological restoration of floodplains
slide-25
SLIDE 25

Mitigation Successes

  • Improved mapping, including statewide LiDAR
  • Communicating risk
  • Better land use planning and watershed

management

  • Improved flood forecasting
  • Promotion of higher floodplain standards
  • Actively encouraging flood insurance

Mitigation Successes

Acquisition and removal of flood prone structures is a high program priority

Over 3,600 structures physically removed from the

  • floodplain. Thousands more protected by

elevation, diversions, floodwalls, levees, pumping stations and flood storage.

Moorhead used 60% fewer sandbags in 2011 for same level of protection in 2009 because of flood reduction projects and use of LiDAR.

Future Challenges

48

  • Memories are short ….. Flood amnesia.
  • Climate change may necessitate additional risk reduction efforts, or higher

levels of protection. The old design standards may no longer be good

  • enough. Is the 1% chance flood the appropriate level of protection?
  • Continued commitment of the legislature. The funding appetite is waning.

When does it end? The most vulnerable/at-risk communities in Minnesota have some level of flood risk reduction.

  • Impoundments are a tough sell. Nameless & faceless. Less impact to the

legislature than a family sobbing in front of a destroyed house with their wet belonging piles at the curb.

slide-49
SLIDE 49

Future Challenges

49

  • Communities with aging flood risk reduction infrastructure may face

changing standards /requirements to maintain certifiable flood protection, but can they afford it?

  • Changes to the National Flood Insurance Program (NFIP) increasing flood

insurance premiums may burden those living in high-risk areas

  • Development pressure
