Peoria stormwater issue reaches a tipping point

June 7th, 2016 by

Forty people gathered in a conference room at the Peoria Riverfront Museum on a snowy January day. Artists, activists, public officials, union representatives, academics, and retirees were there to participate in the first of several planning workshops. They were taking a hard look at the city they call home, and imagining the city they would like it to become.

“The potential is so amazing, its geography, its natural and cultural history,” said Anthony Corso, Peoria’s chief innovation officer and director of the Innovation Team that helped organize the meeting. “It’s a sad state we’re in right now, but with the right motivations we can change direction.”

Corso was charged with addressing one of the most pressing issues Peoria has: combined sewer overflow. When a wet-weather condition arises and rain and melting snow overwhelm the system, this can result in raw sewage dumping into the Illinois River.

The problem, which for years has plagued the city, is being closely watched by the United States and Illinois Environmental Protection Agencies. The message the agencies gave the city was clear: Develop a plan to fix it.

Kara Salazar, sustainable communities Extension specialist with IISG, led that visioning session workshop using a complex, web-based planning tool, Tipping Points and Indicators. The tool is a collaboration of 22 scientists and nine institutions. It compiles research from around the Great Lakes that identifies impacts on water quality from multiple land uses—agriculture and urban—in various locations, particularly near lakes and streams.

Tipping Points uses data to help communities and planners understand how close their watershed is to ecological thresholds and what the watershed will look like if land-use decisions continue on the same course. Cross a tipping point, and you risk not being able to rehabilitate an impacted region.

Before this Peoria project, Tipping Points had not been used on such a heavily urbanized location. Purdue PhD student Jingqiu Chen studied the impacts urbanization has on water quality and developed an additional modeling tool specifically based on Peoria’s stormwater issues. The tool’s ultimate goal is to help communities determine the best way possible—ecologically and economically—to maintain and restore healthy water conditions.

“Peoria has an issue they’re trying to resolve and there are very costly solutions to it, but we’re helping them explore alternatives that are less costly and would provide other environmental benefits as well,” said Dr. Bernie Engle, Purdue department head of Agricultural and Biological Engineering leading the project with Jingqiu Chen.

One way to do that is green infrastructure, which can include parks and open spaces, or installing more porous surfaces. Each of those choices will have positive and negative effects on the community and the goal is to pick the suite that match community values.

The city’s goal is to resolve its problem with 100 percent green infrastructure. If the plan is successful, Peoria would be the first in the nation.

Tipping Points is helping Peoria figure out not only what environmental variables need attention, but how to go about choosing among the many green infrastructure options. The program is so targeted, it can, for instance, even help a community like Peoria set aside land for agritourism or rehabilitate wildlife populations.

Peoria will be getting lots of help along the way. University of Illinois Extension and Illinois Water Resources Center will offer guidance to the city to do its part in addressing the state’s ongoing nutrient loss reduction strategy as well as provide education opportunities.

“We plan to help residents of all ages learn how to manage stormwater in a different way by showing them what they can do—even in their own homes,” said Eliana Brown, IISG stormwater specialist. “They have an opportunity to be part of the stormwater solution that will help protect the Illinois River.”

Asian carp lure new business ideas to Peoria

August 31st, 2015 by

Optimism was high at the International Conference Asian Carp in Peoria a week ago Friday. The goal of this event, sponsored by the Greater Peoria Economic Development Council, was to bolster the economy of the region by networking and sharing ideas and information on marketing Asian carp. And many of the attendees were very interested in exploiting this fishery.

Natural resource managers and entrepreneurs have a similar goal at this point, which is to remove Asian carp from the Illinois River. This bodes well for the river’s future.

IISG was in the room to share outreach information about Asian carp to participants from as far away as China and South America. The audience also represented a variety of professions, including researchers, food service professionals, processors, investors, and more.

In recent years, several Midwest businesses have jumped into the carp market. Schafer Fisheries, for example, has developed new products, such as dog treats and liquid fertilizer, but also processes fillets. Asian carp species have a mild flavor, and the conference crowd was treated to a variety of inventive carp dishes, from spring rolls to chili, which were all delicious.

The “if you can’t beat ‘em, eat ‘em” mantra has reaped some rewards. Matt O’Hara, with Illinois Department of Natural Resources, reported that the three-year catch at Marsielles Pool along the Illinois River has steadily declined. The leading edge of Asian carp moving towards the Great Lakes has stayed miles away from this critical freshwater resource.

If the enthusiasm at the conference translates to successful businesses, at some point they will need to be prepared to diversify when carp species have been reduced to manageable levels. At that point, they may be able to shift to native fish, which, in fact, are more lucrative.

Peoria was also the host for the annual Asian carp bowfishing tournament on Saturday, and IISG was there to talk with participants about how to prevent the spread of Asian carp and other invasive species. Both events were rescheduled from July due to high waters earlier in the summer. As it turns out, flood waters are very good for spawning. It’s likely that we’ll see Asian carp numbers increase in the future because they had a good spawn this year.
