Maybe the most remarkable thing about the Cedar Rapids Flood Control System Master Plan is the most obvious. The leaders and decision-makers put the people before the project.
“What’s the community going to look like?” is how Rob Davis, P.E., M.ASCE, Cedar Rapids’ flood control program manager, described the top priority. “Not ‘What’s the flood system going to look like?’ but ‘What’s the neighborhood going to look like?’”
Cedar Rapids has taken a holistic approach to flood control, and the result is an innovative, flexible master plan and, ultimately, a safer, more resilient community.
ASCE recently added the Iowa flood control system to its Infrastructure #GameChangers, a group of groundbreaking projects representing trends in transportation, water, freight, and energy infrastructure.
The system’s origins go back to 2008 when the Cedar River overflowed its banks and flood levels in the city were 11 feet above the previous record height.
City leaders recognized immediately the need for permanent flood control – “There was never a question of should we do this project. The question’s been how we do this project,” Davis said.
The community was part of the process from the start, with several meetings to discuss solutions strategy.
“We kept talking about that three-legged stool with cost, environmental issues, and social issues,” Davis said. “We really focused on that triple bottom line.”
Davis and his team envisioned a flood plan that would both protect and enhance the city, with a 7.5-mile system of removable walls to maintain natural views and levees that incorporate green space and parks. They developed a concept, in partnership with the U.S. Army Corps of Engineers, and in 2009 began buying properties near the river – about 1,400 in all – to clear the flood plain and prepare the rebuild.
“Our City Council adopted a resolution fairly early on when we were in the recovery stage that gave city staff flexibility to build in sustainability elements,” Davis said. “It wasn’t a blank check, but it was a strong statement by our leaders that they wanted to come back better in the long term.”
Nearly eight years later, the property purchase portion of the project is almost complete. The group worked on the design in 2014-15, with the project bid process underway this year. The holistic approach and collaborative nature of the project have allowed Davis to remain flexible as the master plan develops.
After reconsidering the plan’s potential transportation limitations, the city proposed raising an existing bridge 14 feet to secure a vital river crossing. The state endorsed the plan and it’s been added to the master plan.
“We’re trying to find ways we can tweak our system and make it better while we design it,” Davis said. “Everyone’s in agreement of what we’re going to build. Now it’s up to the engineers to carry it out.”
The project celebrated a tangible sign of progress with a groundbreaking last month.
“It’s an exciting time,” Davis said. “We’ve gotten through all the discussions and the acquisitions and debate.”
The benefits of keeping the flood control plan as part of the community and not separate from the community are already showing as a neighborhood near the river has grown into a city hub for events and retail.
It might not have been part of the master plan, but it’s not a coincidence either.
“The community is reinvesting with the confidence that they will be protected,” Davis said.
