Des Moines is more flood resilient than just a few years ago, public works director Jonathan Gano told the City Council during a presentation last month.

Why it matters: Homes and businesses are better protected against floods, which have caused billions of dollars in damages and multiple deaths caused in recent decades.

Driving the news: Flood insurance will no longer be required for about 170 homeowners in the Highland Park neighborhood once a $20.5 million storm system project is completed next year.

  • That can save owners upwards of $1,400 annually, Patrick Beane, DSM's clean water administrator, tells Axios.

Catch up fast: The city tripled the rate of stormwater projects for flood mitigation after more than 1,800 homes were damaged in 2018.

  • Multiple phases of projects in Beaverdale, Easter Lake and near the Iowa State Fairgrounds are now complete.
  • Polk County also expanded its flood prevention efforts and incentivized a land buffer program in farm areas.

Follow the money: DSM's initiatives cost more than $150 million over a six-year period.

Reality check: Floods remain a concern.

What's next: More than $100 million in additional levee improvements and stormwater projects are in DSM's five-year budget.
