Rio de Flag composite channel could alleviate floods, keep aesthetics

Rio de Flag composite channel could alleviate floods, keep aesthetics

Arizona Daily Sun • September 3rd, 2017 • Corina Vanek

A composite channel that carries some water underground while keeping a visible riverbed above ground could be the solution to flooding issues from the Rio de Flag as well as concerns about the aesthetics of the project.

In a presentation meant to update the public on the flood control project as well as gather ideas for what the public would like to see around the Rio, city project manager James Duval said that while most of the specifics of the project have not changed over the years, citizens now have a chance to weigh in on how they would like the upper portion of the Rio to look.

“I’m happy to see they’re looking at the composite channel,” Rick Miller, a board member of Friends of the Rio de Flag said. “The Friends of the Rio would like to see as much as possible of the natural channel.”

Fellow board member Kathy Flaccus echoed Miller’s sentiment, saying she was glad the city and the Army Corps of Engineers seemed to be listening to what the people wanted to see done with the Rio channel.

“We like seeing the water when it’s running,” Flaccus said. “The Rio is such a wonderful attribute for Flagstaff, it links the entire town.”

Flaccus said earlier plans involved putting all of the water in underground culverts, instead of the composite channels, which was worrisome for her.

“The Rio is too much of an amenity for that,” she said.

Miller said he has been able to track flood control studies for the Rio back to 1972, which were created then as a way to make the decision of what to do to mitigate flooding problems.

Along the upper stem of the river, which runs through downtown Flagstaff, many homes back up nearly to the Rio’s bank. Many of the nearby homes have been purchased by the city, Miller said. The city could use part of the lots for the improved Rio channel and use the remainder for a public amenity, including a FUTS trail similar to the one there now, pocket parks or riparian areas.

According to city calculations, a heavy storm and subsequent flooding could cause nearly $1 billion in damages, with much of the cost coming from an almost complete inundation of Northern Arizona University in the event of a 100-year flood, which means a flood that has a 1 percent chance of happening in any given year.

The composite channels are one of several solutions that have been floated throughout the years of the project, but so far, they have been a favorite of many people who are actively involved in preserving the Rio while looking for ways to mitigate flood damage.

So far, the city has invested bout $15.5 million into flood mitigation from the Rio de Flag, Duval said in his presentation. The Army Corps of Engineers, which will take on the largest financial burden for the project, has spent about $25.2 million so far of what is estimated to be a $106 million project. The remaining cost to the city is about $30 million, Duval said in his presentation. The army Corps of Engineers was authorized to spend more than $100 million on the project in 2016, but that money has not yet been allocated.

Once the improvements are completed, the Southside and much of NAU should no longer be in a floodplain. This would eliminate mandatory flood insurance for residents who live in the area and would make it easier and more cost-effective for building or improving buildings in the area.

Miller said the Friends of the Rio have shifted much of their focus to the social justice issues involved with the Rio’s flooding, and said the improvements on the main stem of the Rio, much of which would happen north of Frances Short Pond, could help alleviate the worry for Southside residents.

“We have to retain the current channel in the Southside, but it would only be carrying the local flow,” Miller said. Without the improvement, water that runs down from north of the city limits flows through the Rio and ends up in the Southside, causing heavy flooding in residential areas.

“It’s an environmental justice issue for the Southside,” Flaccus said. “They must have flood insurance and people can’t sell for the full value of their property. It’s very valuable property, near downtown and the university, but what brings the value down is the flood hazard.”

At the meeting, Duval said he plans to come before the city council in November to discuss funding options for the city. City Manager Josh Copley said the options could include a bond question on the 2018 ballot, a specialized fee or a tax.

“It depends on what council will be inclined to send to voters,” Copley said.

The city does not have ongoing funding budgeted for the Rio project, and Copley said the city must continue contributing to the project to pay for a contractor’s services and to keep the Army Corps of Engineers involved.

“As the money has come through, we have been able to piecemeal the project,” Copley said. “Now it’s time to put it all together.”

THANK YOU!

A big thanks to all of the hard-working volunteers who came out to cleanup and pull weeds along the Rio de Flag on Sunday, September 3rd as part of Colorado River Days! This motivated group of 10 people picked up 5 bags of trash and 1 bag of recycling along a half-mile stretch of watershed including the Rio de Flag and one of its tributaries, Switzer Canyon Wash.

Continue celebrating Colorado River Days with more interesting events through September 15th at: http://www.coloradoriverdaysflagstaff.org/
