2020 Flood Response

04/09/20

High river levels and rain in the forecast could cause the closure of River Dr east of 3rd and 4th Streets due to water over the road. For your safety and the safety of responders, please do not drive through water over the road. 

Keep in mind with S Marquette closed at River Dr, the Dog Off-Leash Park south of River Dr will be closed until river levels recede, and the road is re-opened. There is another option, though.  Consider social distancing in new surroundings on higher ground at the off-leash park at 3200 N Marquette. 

As a reminder:

  • River Dr is closed between Division and 3rd/4th Streets due to water over the road and the installation of the temporary flood defense system between Iowa and Pershing.  View current flood detour at this link. 
  • Many riverfront locations can still be accessed using north/south streets.
  • S Concord is closed between River Dr and Wapello. You will need to access the Compost Facility via Rockingham Rd/Hwy 22 to Wapello.
  • Sand and sandbags are available for pick up. You will need to place a request for service by calling 563.326.7923 during business hours or online at https://yourgov.cartegraph.com/ to arrange for pick up.

We are monitoring conditions as always and are prepared to respond as needed to changing conditions. 

04/08/20

The City is updating the current flood detour to better accommodate traffic while river levels allow. The detour will change if River Dr begins to further cover near Federal with river rise.  View a copy of the current detour at this link. 

Flash flooding on River Dr is possible during rain events. For your safety, please do not drive through water over the road.

04/07/20

As a City positioned on the Mississippi River, flooding is part of our reality. And we are ready.

Due to forecast river levels of 17.5 FT by Fri Apr 10 and the possibility for active weather to set up over the next two weeks, we are initiating the next steps in our flood plan. These actions require closing River Dr between Division St and Bridge Ave for public safety, and the installation of the City’s temporary flood defense system between Pershing and Iowa.  The closure and detour will go into effect at 2 PM Tue Apr 7. Access riverfront locations not impacted at these levels using north/south streets.

As closures are placed, please be reminded driving or walking through floodwater is not safe. Even when the water looks really shallow and passable, you never know what is beneath that water or how deep it may be.

The City continues to monitor conditions closely with the National Weather Service and is prepared to respond to changing river levels.

Are you an impacted property owner?

  • Sand and sandbags are available for pick up. You will need to place a request for service by calling 563.326.7923 during business hours or online at https://yourgov.cartegraph.com/ to arrange for pick up.

We will issue another update as conditions change.


04/01/20

Saturday morning’s downpour resulted in flash flooding and spiking river levels.  Things have quieted a bit, but we are not out of the woods yet.  The Mississippi is forecast to hover around 16/16.5 FT into next week; however, run-off and snowmelt to the north may contribute to further river rise next week.  Too early to tell.

The City continues to monitor conditions closely with the National Weather Service and are prepared to respond to changing river levels. 

Are you an impacted property owner?

  • Sand and sandbags are available for pick up. You will need to place a request for service by calling 563.326.7923 during business hours or online at https://yourgov.cartegraph.com/ to arrange for pick up.

The Mississippi River forecast has fluctuated a bit since last week.  The current river level is hovering 15 FT and expected to reach 15.5 FT around Thu Mar 26.  That being said, the river may see additional rises later this week and early next week, depending on precipitation expected later this week.  Public works remain prepared and encourage anyone in the river floodplain below 18 FT to keep an eye on things.

Are you an impacted property owner?

  • Sand and sandbags will be available for pick up beginning at 7 AM Mon Mar 23. You will need to place a request for service by calling 563.326.7923 during business hours or online at https://yourgov.cartegraph.com/.

Watch for updates later this week.

Crews are prepared to respond to arriving conditions. 

03/20/20

The Mississippi is on the rise. Time to activate that flood plan. As crews prepare for the river to rise, we encourage individuals affected at river levels below 18 FT to begin preparing too. At last check, the river is predicted to reach 16 FT late next week and possibly crest near 17.5 FT by Wed Apr 1. At these river levels, there are certain things you may want to know about.

Are you an impacted property owner?

  • Sand and sandbags will be available for pick up beginning at 7 AM Mon Mar 23. You will need to place a request for service by calling 563.326.7923 during business hours or online at https://yourgov.cartegraph.com/.

Do you travel near the riverfront?

  • S Concord will be closed between River Dr and Wapello at the end of the day, Fri Mar 20. This means you will need to access the Compost Facility via Rockingham Rd/Hwy 22 to Wapello.

Do you recreate near the riverfront?

  • Credit Island will likely be closed to the public beginning Mon Mar 23.
  • Expect the riverfront bike path between Credit Island and Marquette to close sometime over the weekend.

Additional actions will occur as the river rises into next week. 

In the Downtown, expect various lane reductions along River Dr as the river swells above 16.5 FT. At this time, the City does not plan to set its temporary flood defense system between Iowa and Pershing because it is not necessary at predicted river levels. The river will just be allowed to seek its own level over River Dr. Should predictions exceed 18 FT, the focus will shift, and the defense system will be installed.

Staff will begin setting the temporary flood wall around Modern Woodmen Park sometime Mon, Mar 23. When this happens, Gaines St south of River Dr will be closed. 

Watch for updates next Mon, Mar 23.

Crews are prepared to respond to arriving conditions.

Property owners impacted at 24 FT river level and below, will be receiving a letter in the mail about a first-floor elevation survey that is being conducted. The survey is being conducted to gather data that supports the analysis and evaluation of future flood mitigation and defense options. Property owners will be provided a copy of the survey when the survey portion of the project is complete sometime in May. Contact public works by e-mail at dpw@davenportiowa.com if you live in the floodplain along the riverfront and have not received a letter by Tue Mar 19.

We were thrilled to see so many Davenport property owners, organizations and public entities come together for the LEAP into Flood Preparation event that took place this weekend. 

As a city along the banks of the Mississippi River, flooding is a reality. The good news is this: we’re resilient. And, we’re ready. To help you prepare for potential spring flooding, please visit www.BePreparedDavenport.com

02/27/20

Chances remain high for moderate to major flooding this spring, according to our friends at the National Weather Service, who issued their 2nd of 3 spring flood briefings. Keep in mind the forecast is still several weeks out.  Preferable snowmelt activity and less than average precipitation could be in our favor as we monitor conditions through March.

As the city prepares for flooding, property owners located in the flood plain should consider preparing for the possibility of a flood, too. An excellent opportunity to prepare is this Sat Feb 29 at the LEAP into Flood Preparedness event being held at Modern Woodmen Park. City staff, the American Red Cross, flood mitigation system vendors, the National Weather Service, and many other agencies and vendors will be available to discuss available resources.  

As an adaptive and resilient community located on the banks of the Mississippi River, we will adjust and recover should river levels rise above 18 FT again this year.

Watch for more updates in the coming weeks.

02/23/20

Build a wall, keep River Dr open, and resource and funding limitations were all topics of discussion at a Mayor and Council work session on Sat Feb 22.  

The work session was held to discuss the objectives for a request for proposals (RFP) to enhance the City’s flood plan and identify flood risk reduction measures that might be implemented in the future.

Operational considerations, climate trends, an open riverfront, feasibility, and downstream impacts were at the heart of the conversation that resulted in direction for the RFP.

Discussion about what should be included was supported by input from Larry Weber of the University of Iowa IIHR and Iowa Flood Center and Jason Smith with the Corps of Engineers and Silver Jackets.

The RFP is expected to go out for bid soon and be followed by selecting a consultant within the next three to four months.  The scope of work for the RFP will incorporate information from existing plans and studies and include public input to develop an overall vision and objective for Davenport’s riverfront and flood fighting.

Completion of the scope of work under the RFP is expected before the end of 2021 and will include several options for the Mayor and Council to consider.  Options to consider will include boundaries for over-land flooding and may include public/private partnerships as well as structural and non-structural risk reduction measures.

Highlights of the work session included staff updates on preparations for 2020, including the launch of a new flood information tool to assist property owners in the floodplain, beprepareddavenport.com.

02/18/20
There will be a Council Work Session on Flooding on Sat Feb 22 beginning at 8:30 AM in Council Chambers to discuss flooding and planning efforts.  The event is open to the public; however, time for public comment is not provided.

Flood Season 2020 Begins with Preparing to be an Even More Resilient Community

Our friends at the National Weather Service issued their 1st of 3 spring flood briefings this morning, and chances are high there may be flooding in our community this spring. Last year’s flood was intense. But above all else, Davenport is resilient, and we came out of it with more strength!

Keep in mind the forecast is early, but be reassured we are ready. Experiences from 2019 have been incorporated into the City’s flood plan, and we are already preparing for the upcoming flood season. We have ensured all flood response methods are in proper working order, and recently conducted refresher training with the Corps of Engineers.

Be aware adjustments will need to be made by everyone should river levels rise above 18 FT again this year. Planned construction activities, detours, and special events impacts are possible.

If you are a property or business owner in the floodplain, begin thinking about preparing for the possibility of a flood. An excellent opportunity to prepare is coming up, when the City and Scott County EMA host a LEAP into Flood Preparedness event on Sat Feb 29 at Modern Woodmen Park.  City staff, the American Red Cross, flood mitigation system vendors, the National Weather Service, and many other agencies and vendors will be available to discuss available resources.   The event is also a great informational opportunity for those located in the flood plain along the City’s many miles of creeks and streams.

Like any big city, Davenport has had hard times. But, as history has demonstrated, we’re also resilient, emerging from hardship with more strength, courage, and knowledge to prepare us for the future.

Expect more updates as we prepare for the 2020 flood season.

Preparing now for a more resilient community tomorrow.
