FLOOD: IC/Coralville Flood Info
IOWA CITY, IA (CBS2/FOX28) -- The United States Army Corps of Engineers reports that the inflows into the Coralville Reservoir have peaked today, Friday, July 4, at 29,000 cfs, with outflows at 18,000 cfs. The reservoir is currently predicted to crest at 710 feet above sea level -- two feet below the emergency spillway -- on Thursday, July 10. Although this news is encouraging, it is important to note that the river projections can change quickly if there are additional heavy rains in the next few weeks.
Citizens are reminded to stay away from riverbanks and barricaded areas. The river forecast for Iowa City can be monitored at http://water.weather.gov/ahps2/hydrograph.php?wfo=dvn&gage=iowi4. Projections are based on 24-hour rainfall forecast and will change based on additional precipitation totals.
Current road conditions
North Dubuque Street is closed from Foster Road to Park Road until further notice. North Dodge Street (Highway 1), including the Interstate 80 interchange, is the recommended detour route for motorists who typically use Dubuque Street to access Iowa City.
Because of the closure, the Weekday & Night/Weekend Manville Heights bus routes will be significantly altered. More information about the transit changes can be found here: http://www.icgov.org/apps/news/?newsID=9762.
City officials continue to monitor Rocky Shore Drive and South Gilbert Street. With current weather conditions, these locations should remain accessible, though additional rainfall may impact travel on these roads.
All motorists through the Iowa City metropolitan area are requested to be patient due to changing traffic patterns as a result of road closures, and are encouraged to allow for extra time when traveling.
Parks and trail closures
Lower City Park is closed until further notice. Upper City Park is still open. Terrill Mill Park, including the skateboard park, is closed. Citizens are asked to stay out of both parks for their own safety, as water may be deeper than it appears and currents deceptive.
The City has closed the Iowa River Corridor trail from Napoleon Park to Burlington Street due to flood waters until further notice.
Sand bagging efforts
The City of Iowa City has had a good turnout of sand bagging volunteers this morning. This, combined with the revised reservoir forecast has allowed for the production of enough sand bags to meet the City's current needs. The City will suspend its sand bagging operations at noon today and will not resume unless or until the weather changes.

CORALVILLE, IOWA--The U.S. Army Corps of Engineers has indicated that, based on recent and
projected rainfall, the Coralville Reservoir may go over the emergency spillway in the coming
Daily rainfall in the Iowa River watershed can affect this type of event significantly. The City of
Coralville is in daily communication with the Corps of Engineers and National Weather Service for
updates, and works with Johnson County Emergency Management and other local governments to
develop a coordinated response for this type of event.
The Corps will increase outflow rates to 15,000 cubic feet per second today; outflows are
anticipated to increase to 20,000 cubic feet per second on Friday, July 4.
Community Flood Response
Following flooding in 1993 and 2008, the City of Coralville has made significant improvements
and investments in flood mitigation infrastructure for protection of low-lying areas from
floodwaters on Clear Creek and the Iowa River. City staff are currently monitoring the release
rates on the Iowa River and water flows on Clear Creek, in conjunction with the current status of
flood mitigation infrastructure improvements, to determine the most efficient and appropriate
response to this event.
Today and tomorrow, in cooperation with Johnson County Emergency Management and with
assistance from the City of North Liberty, the City of Coralville will deploy 1,300 feet of HESCO
barriers on the south side of Clear Creek from 1st Avenue westward to protect the properties and
infrastructure in that area, including the south side of Highway 6.
The City is also reviewing river levels at which temporary floodwalls will need to be installed to
protect certain areas from flooding. At this time, temporary floodwalls will be installed along the
Iowa River behind the Iowa River Power Restaurant. The City will continue to monitor elevations
and the Corps' projections and install temporary protective measures as necessary.
Sandbagging of individual properties is not necessary in Coralville. The City is coordinating an
area-wide response based on land elevations and permanent flood protection measures to
maximize the available resources. As a result, Coralville does not have sandbags available for
residents to pick up.
Construction on Coral Ridge Avenue and 1st Avenue in Coralville, along with the likely closure of
Dubuque Street in Iowa City, may require that motorists allow extra time as they travel to their
Coralville 4thFEST activities will continue as scheduled from July 3 through 6. For more
information, visit www.coralville.org/4thFEST.
Flood Protection Infrastructure
A summary of the improvements made since 2008 for flood protection include:
[?] Reconstructed 1st Avenue bridge over Clear Creek: The bridge is higher and longer to
allow the 100 year flood to pass underneath.
[?] Improved storm sewer system on 1st Avenue from Clear Creek to 6th Street.
[?] Constructed four storm water pump stations along the Iowa River from Clear Creek to
[?] Constructed flood protection walls and berms along the former Edgewater Drive.
[?] Installed duckbills and sluice gates in 10 locations in the existing storm water system to
prevent back-up of high water levels in the Iowa River and Clear Creek from flooding
[?] Constructed earthen berms, permanent and removable flood walls along the west side
of Clear Creek from Highway 6 to 1st Avenue and along Biscuit Creek from Clear Creek
to 5th Street, and ponds along Biscuit Creek.
[?] Constructed two new storm water pump stations on Clear Creek, upgraded two existing
storm water pump stations, and flood-proofed the 3rd Avenue sanitary sewer lift
[?] Constructed flood protection improvements along the Iowa River from west of Rocky
Shore Drive to the north end of the Iowa River Power Company Restaurant parking lot.
This project raised the CRANDIC railroad embankment, raised and lengthened the
CRANDIC railroad Clear Creek Bridge, and constructed earthen berms and concrete
flood walls along the Hawkeye Ready Mix and MidAmerican substation sites,
permanent and removable flood walls along the river side of the Iowa River Power Co.
Restaurant, and removable flood walls along the IRP Restaurant parking lot.

Detours and street information
North Dubuque Street has been reduced to one southbound lane between Foster Road and Park Road and northbound lanes are currently flooded. One lane of the southbound section is being used to facilitate the installation of a Hesco flood barrier wall in front of Mayflower Residence Hall. Northbound travelers should use the Dodge Street exit (exit 246) on Interstate 80, to exit Iowa City. Due to the rising river level predicted by the U.S. Army Corps of Engineers, it is anticipated that Dubuque Street will close completely to traffic later today. All motorists through the Iowa City metropolitan area are requested to be patient due to changing traffic patterns as a result of road closures, and are encouraged to allow for extra time when traveling.
* Do not play in flood waters. This is especially true for children and pets. Flood waters may contain snakes, insects, sharp objects and debris, oil, gasoline, industrial waste, and raw sewage. Seek immediate medical attention if anyone in your family becomes injured or ill. Wash hands with soap and clean water or use an alcohol-based sanitizer if you come in contact with flood waters.
* Do not walk through moving water. As little as 6 inches of moving water can make you fall.
* Do not drive across a flooded road. Avoid areas already flooded, especially if the water is flowing fast. Never attempt to cross flowing streams. Six inches of water will reach the bottom of most passenger cars causing loss of control and possible stalling. It only takes 18 inches of water to lift your car or SUV. Once your vehicle becomes buoyant, the water will easily push it sideways. Most vehicles will then tend to roll over, trapping those inside and washing them downstream.
Governor's Proclamation of Disaster Emergency
Governor Terry Branstad issued a proclamation of disaster emergency for Johnson County in response to flooding and severe weather. The governor's proclamation allows State resources to be utilized to respond to and recover from the effects of these storms. In addition, the proclamation activates the Iowa Individual Assistance Program. The Iowa Individual Assistance Program provides grants of up to $5,000 for households with incomes up to 200 percent of the federal poverty level, or a maximum annual income of $39,580, for a family of three. Grants are available for home or car repairs, replacement of clothing or food, and for the expense of temporary housing. Original receipts are required for those seeking reimbursement for actual expenses related to storm recovery. The grant application and instructions are available on the Iowa Department of Human Services website. Potential applicants have 45 days from the date of the proclamation to submit a claim. Individuals who are eligible for state assistance can contact HACAP at 319-393-7811.
Iowa City officials will continue to closely monitor Iowa River and area creek levels.
