PAC Recommends Argo Dam Bypass

Ann Arbor park advisory commission meeting (Oct. 19, 2010): Though the proposal facing park advisory commissioners wasn’t directly related to the question of whether to keep or remove Argo Dam, PAC heard from nearly a dozen people during public commentary who aired their views on that topic.

The resolution that PAC ultimately approved was a recommendation to build a bypass channel in the Argo Dam headrace for $988,170, and to add whitewater features for an additional $180,000. The $1,168,170 project would be designed by Gary Lacy of Boulder, Colo., and built by TSP Environmental, a Livonia firm.

City staff said this was the only proposal submitted that met the requirements laid out in the city’s request for proposals (RFP). The plan calls for removing the canoe portage, replacing it with a series of “drop pools” so that no portage is required. The project will also improve accessibility of the path – which is part of Washtenaw County’s Border-to-Border trail – and address problems in the headrace embankment that were identified by state officials. The work is tied to a consent agreement that the city reached with the state in May, laying out steps that the city must take to deal with some long-outstanding structural issues.

Commissioner Tim Berla voted against the resolution, calling it a “protest vote” because removal of Argo Dam hadn’t been considered as an option – that same point was made by several speakers during public commentary. Park staff has indicated that this project doesn’t preclude removing Argo Dam in the future, if that’s a decision that the community makes.

Funding for the project is available from the city’s Parks Rehabilitation & Development millage and the drinking water fund, according to city staff. An additional $50,000 might be available from the Washtenaw County Parks & Recreation Commission, to help pay for a portion of the project related to the county’s Border-to-Border trail.

Several people – both commissioners and speakers during public commentary – questioned the appropriateness of using the water fund for this purpose, saying that Argo dam has nothing to do with drinking water. Local attorney Scott Munzel argued that using the water fund to pay for dam-related projects might be illegal, based on case law, because it’s being used as a way to skirt the Headlee Amendment. Munzel is a board member of the Huron River Watershed Council, which has lobbied vigorously to remove the dam for environmental reasons.

The proposal for reconstruction of the headrace and embankment will now be forwarded to city council.

Also at Tuesday’s meeting, PAC members heard an update from parks staff about this season’s activities at the city’s three outdoor public pools – at Buhr, Fuller and Veterans Memorial parks. The former supervisor for Buhr Park Pool, Gayle LaVictoire, also gave a brief presentation to commissioners about her new job as volunteer outreach coordinator for the parks system, a newly created position.

And at the end of the meeting, Colin Smith, manager of parks and recreation, announced that the Ann Arbor Senior Center received more residents’ votes than other city facilities in a recent contest sponsored by Stonyfield Farm, and will receive $15,000 from that firm. [Full Story]

MDEQ to Ann Arbor: Close Argo Millrace

As part of an intro to an interview with the chair of the Ann Arbor Park Advisory Commission, Scott Rosencrans, which The Chronicle published on Aug. 25, we reported that a letter from the Michigan Department of Environmental Quality had been sent to the city of Ann Arbor. The MDEQ letter included an order to close the millrace at Argo Dam.

The communication from the state agency didn’t come out of the blue – it was a reply to a request sent to MDEQ by the city of Ann Arbor asking for an extension to a July 31, 2009 deadline for action on Argo Dam.

With the text of both letters now available, we take a look at those communications, after briefly considering some historical context. That context dates back to a 2004 letter from the MDEQ about toe drains in the earthen berm next to the dam, and includes formation of a study committee, a public engagement process that extended over most of the first half of this year, recommendations from the city’s Park Advisory Commission and Environmental Commission, and a city council work session.

A key date from the most recent MDEQ letter is Nov. 1, 2009, by which time it has ordered the city of Ann Arbor to close off and drain the millrace. But it leaves both the dam-in and dam-out options available to the city. On a dam-in scenario, the MDEQ wants the toe drains in the earthen berm repaired by Dec. 31, 2010. On a dam-out scenario, the MDEQ wants the removal completed by December 2012. Either way, the city is supposed to have its study of options completed by April 30, 2010.

Based on a Tuesday phone conversation with Matt Naud, the city’s environmental coordinator, one possible timeline for next steps would have the city council conducting a mid-September work session on the topic, with clear direction coming at the council’s second meeting in September. Whatever that direction from council is, said Naud, it’s going to start costing money to implement the next steps – on the order of five-figure dollar amounts at least. [Full Story]
