Iowa Water Center City Spotlight: Cedar Rapids

By Joe Otto, Communications Specialist at the Iowa Water Center

The City Spotlight series highlights ongoing efforts by Iowans living in cities to address water issues impacting their neighborhoods.

 2019 will be a big year for flood control planning in downtown Cedar Rapids. The city’s budget for the 2020 fiscal year includes $35 to $40 million-dollars for flood protection – nearly double the amount of last year. With the 2020 fiscal year beginning on July 1 of this year, officials are actively exploring various options and drawing up plans. On top of the significant jump in local funding is an infusion of federal dollars amounting to $76 million in grants and $41 million in low-interest loans.

Already underway is the construction of a $14.2 million-dollar floodwall and pump station to protect the Quaker Oats factory, which sits downtown on the banks of the Cedar. This project was started during the previous fiscal year and is the largest and most expensive currently underway. Because rail access is crucial to the manufacturing facility, the tracks of the Union Pacific Railroad will be realigned and outfitted with a floodgate. The railroad floodgate was partially funded by a grant from the Iowa Department of Transportation.

The city’s goal is to withstand another Flood of 2008. At the present, the city prepares for floods by setting up temporary defenses: movable barriers and portable pumping stations. The long-term vision is to integrate these defenses into a more permanent system. Additional pumps at existing pumping stations would reduce the city’s reliance on portable pumps, and enable city staff to focus on other tasks during times of emergency.

Future plans include large, rolling floodgates along major streets – similar to that constructed near Birdland Park and Guthrie Ave. in downtown Des Moines after the Floods of 1993.  A floodgate on 16th Ave where it spans the Cedar River would effectively link two sections of concrete wall on either side of the bridge. In the event of a flood, the gate would roll into place and seal up a vulnerable breach in the city’s flood defenses.

But the city is also committed to keeping the Cedar River connected to the downtown area. The 8th Avenue bridge is slated for replacement, which may also include pump stations, restrooms for the city’s outdoor amphitheater, a scenic overlook of the city’s riverscape, or possibly a vendor space for restaurants or shops. Upgrades to a recreational trail along the Sinclair Levee will include more benches and monuments honoring local historical figures. The city’s flood control manager, Rob Davis, has stated that the city intends to stick to its master plan, “which is not to wall us off from the river.” By incorporating economic and recreational development of the riverfront area into its flood protection planning, the city believes interaction with the Cedar River will remain a valuable attraction, despite the ongoing struggle to control its more uncontrollable elements.

Cedar Rapids has successfully directed state and federal funding streams into their downtown flood protection plans. Part of their success hinges on the city’s use of bonding and property taxes to raise matching funds from local sources – often a requirement for high-dollar, competitive grant programs. In 2018 the City Council approved a $264 million-dollar bonding plan, spread out over ten years, to raise the necessary local funds. The plan involves property tax raises of about 22 cents per year. As reported by the Cedar Rapids Gazette, the sale of these bonds will be subject to a future vote by the City Council.

Anyone interested in commenting on the planning process as it moves forward is encouraged to attend regular City Council meetings. The City Council also intends to gather public input by scheduling public hearings, which residents are also encouraged to attend.

Iowa Water Center City Spotlight: Mason City

By Joe Otto, Communications Specialist at the Iowa Water Center

The City Spotlight series highlights ongoing efforts by Iowans living in cities to address water issues impacting their neighborhoods.

Suburbanization in Iowa’s cities and towns has been well underway since the 1990s and beyond. Homeowners in the suburbs enjoy closer-knit neighborhoods and quieter streets, but recently residents in two subdivisions of Mason City took action to combat a lingering exposure to flooding that has recently become more problematic.

Following a wet summer of 2018, Mason City is exploring options to better combat flooding on its east side. Residents in the Asbury and Eastbrooke neighborhoods met to hear the City’s plans to help protect their homes from future flooding. Damaging floods during the summer of 2018 caused the City to explore upgrades to their storm water and drainage infrastructure that was unable to hold back the rising waters.

The two suburban neighborhoods are located right next to one another. Both are in the Winnebago River watershed, but only Asbury is right along the Winnebago River. Five hundred and ninety-seven square miles of land in the Winnebago river valley drains into the Asbury neighborhood, including Clear Lake and the upper course of the Winnebago, from Mason City, past Forest City and Fertile, to its source at Bear Lake in Minnesota (Iowa Flood Center). Eastbrooke, on the other hand, sits along a small branch of the Winnebago, Ideal Creek, that outlets into the river just downstream from the subdivision. The drainage area of the Ideal Creek watershed above Eastbrooke is 9.4 square miles, which spans northward as far as 305th Street in Cerro Gordo County (Iowa Flood Center). Although these watersheds are very different in size, they do share a common problem. When floodwaters threaten homeowners on the banks of the Winnebago, the river is too swollen to allow water from Ideal Creek to discharge. The result is that both neighborhoods experience flooded basements and overworked sump pumps.

Two plans are under consideration. The first is to build a new drain with sufficient capacity. The current one was built in the 1980s, before these neighborhoods existed. In the 1980s the lands in question were farmed and tiled with 16-inch drains, but when then subdivisions were formed in the 1990s the tile was abandoned and left in place. In response to complaints, in 2016 the City redirected some of the tile into a storm sewer and cleared the system of tree roots. The cost to replace the old system is about $300,000.

The second plan is for the property owners to petition their City government to form a drainage district. Under Iowa law, residents seeking relief from overflow on their lands can form a special taxing district that exists apart from the city’s general taxing structure. Property within the district is taxed to pay for new drainage systems. Option two would require close cooperation with the Cerro Gordo County Supervisors and the Mason City Council, as both have jurisdiction in drainage district matters. Other cities have followed this route, such as the City of Storm Lake in Buena Vista County. If homeowners explore this option they might consider reaching out to their neighbors to the west to learn more about the pros and cons of forming a drainage district. Another source of information is the City of Spirit Lake in Dickinson County, where a drainage district includes much of the city as well as neighboring agricultural land. Mason City officials have experience in drainage matters as well, as part of a Cerro Gordo County drainage district, No. 17, lies within the city limits on the west side. The outlet of the ditch is Chelsea Creek, just downstream from the Mason City Country Club. An area of 2 square miles drains into this district (Iowa Flood Center). This option is expected to cost at minimum $50,000 and would enable residents to more easily request and pay for future maintenance and repairs.

The problems faced by residents of Asbury and Eastbrooke show the unintended consequences of developing suburbs in flood-prone areas. Their efforts to work with local governments, both city and county, to solve these problems is laudable and may provide an example to other Iowans living in similarly-impacted areas.

City Officials commissioned the Mason City-based engineering firm of WHKS to perform the study. As first reported by KAAL-TV, the recent public meeting was held on December 5th and was part of the planning process.  City Officials are accepting public comments on this project and expect to issue a final report by the end of December. Readers interested in commenting or learning more about Mason City’s planning process should contact the Mason City engineer’s office at engr@masoncity.net or 641-421-3605. To learn more about the county’s management of a drainage district that includes lands within the limits of a city, contact the Cerro Gordo County Auditor’s office at webdrainage@cgcounty.org or 641-421-3064.
