PAC unanimously recommended awarding a nearly $1 million contract to RMD Holdings of Chesterfield, Michigan, for renovation of ballfields at Veterans Memorial Park, West Park and Southeast Area Park. If approved by the city council, work would begin after the 2012 summer season. Ann Arbor Rec & Ed – a unit of the Ann Arbor Public Schools – plans to cancel its fall season in light of the project. Teams playing in Rec & Ed programs are the primary users of these fields.

Commissioners also got an update on the status of West Park renovations – specifically, how problems with an underground stormwater system are being addressed. City engineer Nick Hutchinson described plans for repairing the system, saying that legal issues are still being worked out, but the project will likely be completed by July of 2012. A public forum will be held on Feb. 13 at Slauson Middle School to update residents. At a similar meeting held in mid-January, residents raised concerns over whether the situation in West Park has caused flooding in nearby basements.

Also at PAC’s Jan. 24 meeting, commissioner Gwen Nystuen urged the group to consider taking action on the Allen Creek greenway, in light of remarks made by mayor John Hieftje at the city council’s Jan. 23 meeting regarding the city-owned 415 W. Washington property. Colin Smith, the city’s manager of parks and recreation, reported that there’s been discussion about possibly applying for a state grant to help fund the greenway, but the timeline for applying this year is tight. He also suggested that an initial step would be to develop a master plan for the greenway, as recommended in the city’s parks, recreation and open space plan.

Near the beginning of the meeting, commissioner Sam Offen introduced the new executive director for the Leslie Science & Nature Center, Susan Westhoff, who spoke briefly to commissioners. Offen is a board member of the center, a nonprofit that’s located on city property.

Ballfield Renovations

The main action item on the Jan. 24 agenda was a resolution recommending a nearly $1 million contract to renovate softball and baseball fields at three city parks.

If approved by the city council, the $982,333 contract would be awarded to RMD Holdings of Chesterfield, Michigan. That amount includes a $893,030 base bid plus a 10% contingency of $89,303. It was the lowest of four bids received for the project, which will focus on the fenced ballparks at Veterans Memorial Park, West Park and Southeast Area Park. Originally, the city had intended to include fields at Allmendinger Park as well, but bids came in higher than expected, and that work was eliminated from the project.

The renovations have been in the works for more than two years. At PAC’s September 2010 meeting, commissioner David Barrett gave a report on the condition of the city’s ballparks after personally surveying them. [.pdf file of Barrett's ballpark report] According to a staff memo accompanying the Jan. 24 resolution, no major restoration work has been done on the fields in more than 10 years.

Staff from Ann Arbor Rec & Ed, a unit of the public school system, will work with city staff on this project – Rec & Ed programs are the primary users of these fields. Construction will likely begin in mid-August of 2012, with fields ready for use again in early spring of 2013. Rec & Ed plans to cancel its fall season to accommodate the project.

Funding will be drawn from three sources: (1) $250,000 from the approved FY 2012 parks maintenance and capital improvements millage budget; (2) $64,000 from an unobligated remaining fund balance in the expired park repair and restoration millage; and (3) $668,333 from the unobligated fund balance of the existing parks maintenance and capital improvements millage.

Deputy parks manager Jeff Straw and Matt Warba, the city’s supervisor of field operations, briefed PAC on the proposal. Straw noted that in collecting feedback for the 2010 update to the parks, recreation and open space (PROS) plan, the city heard loud and clear that people wanted better maintenance of the fields. The fields – used for baseball, softball and kickball – drew more than 5,000 players during the summer and fall seasons in 2011, Straw said.

Warba noted that when the city had a larger parks staff, renovations of the fields occurred every 10 years. Now, that’s no longer possible to do in-house, he said. Describing the current conditions of the fields, Warba said they are poorly graded, with poor drainage that results in water pooling in the infield, which limits play. The material used for the infield makes it dusty in the summer, and doesn’t allow water to drain quickly when it rains.

For the outfields, the playing surfaces are uneven, Warba said, the turf is in poor condition, and the warning tracks are filled with weeds. Fencing is deteriorating and damaged, and many of the backstops don’t have overhangs.

Upgrades will include regrading the infields, removing the infield lip, replacing the existing infield material with red clay, and installing drainage around the infield’s perimeter. Fencing will be replaced, automated irrigation systems will be installed, field turf will be restored, and concrete will be used for floors of the dugouts and bleacher pads.

Warba told commissioners that Stantec had drawn up designs for the project, and that the lowest “responsible” bid came from RMD Holdings, a company with prior experience doing this work.

Ballfield Renovations: Commission Discussion

Karen Levin asked whether other fields in the city’s parks system can be used to play on during the renovations. Warba said there are 24 other neighborhood fields available. The next phase of this project will be upgrading those as well, he said. Straw added that Rec & Ed decided to cancel its fall season in part because lighting would be a challenge – most of the other ballfields don’t have lights.

Colin Smith, the city’s manager of parks and recreation, noted that no matter how the renovations are handled, it will be inconvenient. Rec & Ed staff felt this would be the best approach, he said. Rec & Ed director Sara Aeschbach told commissioners that players had been surveyed about their preferences, and the strong preference was to preserve the summer season. Using the neighborhood ballparks is too difficult in the fall, because it gets dark earlier. She said players are excited that the fields will be improved.

Gwen Nystuen asked about the material that would be used under the team benches. Will it be a pervious surface? Water drainage is important, she noted. Warba replied that the area will be designed with an angle to allow water to flow off the surface. Pervious materials weren’t considered, he said, though there’s still time to make changes.

Colin Smith, Ann Arbor's parks and recreation manager.

Smith noted that the majority of players wear cleats, which would create problems for any pervious surface. He also pointed out that significant stormwater improvements will be made in that section of Veterans Memorial Park, as part of the Dexter-Ann Arbor street repair project.

Nystuen said that in general, whenever they can install pervious surfaces, it will make a difference in helping address stormwater runoff.

Christopher Taylor asked whether the ballpark renovations would coordinate in any way with the possible skatepark construction at Vets. Smith replied that it’s unlikely the skatepark construction will begin by August – it’s more likely that work on the project will start in the spring of 2013. In response to another query from Taylor, Smith indicated that construction equipment used to build the skatepark isn’t expected to damage the work done on the ballfields.

Mike Anglin said he assumed that the parks staff had coordinated this project with the road work being done along Dexter-Ann Arbor. Yes, Smith said. The stretch of Dexter-Ann Arbor along Veterans Memorial Park, east of Maple, will likely be closed from April through November. That’s another good reason for the fall season to be canceled, Smith said, adding that a lot of coordination will be needed.

Julie Grand observed that rates for using the fields at Fuller and Olson parks increased after those fields were renovated. Would rates also be increased at the ballfields after renovations?

Aeschbach said that Rec & Ed charges fees to cover the cost of prepping the fields for play, and those costs won’t change. It’s up to the city, she said, to set the actual rental rates for the fields. Many user groups no longer play on city fields because of the damaged conditions, she said, so demand isn’t high. Perhaps after the fields are renovated, the city can check to see if those groups will return and pay a higher rate.

Smith noted that this project is in line with the philosophy of taking care of and restoring what the city already owns. The ballfields are eyesores, he said, and not good for playing. In addition, Veterans Memorial Park is located at one of the major entry points into town – the corner of Maple and Dexter-Ann Arbor roads. The area needs attention, he said, and the city is undertaking a major effort to do that, in part to respond to feedback from users.

Outcome: Commissioner voted unanimously to recommend approval of the $982,333 contract with RMD Holdings for ballfield renovations at Veterans Memorial Park, West Park and Southeast Area Park. The recommendation will be forwarded to city council for consideration.

West Park Update

Commissioners had received an update on problems at West Park nearly a year ago, when Craig Hupy – head of systems planning for the city – spoke at PAC’s February 2011 meeting. At that time, Hupy had described the situation with the stormwater infrastructure there as a “catastrophic failure.”

PAC got a more detailed briefing at its Jan. 24 meeting. Parks planner Amy Kuras introduced Nick Hutchinson, a civil engineer and one of the project managers in the city’s public services unit, who was on hand to give an update on the status of swirl concentrators at West Park. It was a shortened version of a similar presentation he’d given at a public forum on the topic earlier in January. Kuras reported that forum had been well-attended.

Nick Hutchinson, an engineer and project manager with the city of Ann Arbor, updated PAC on the status of infrastructure renovations at West Park.

Hutchinson began by giving a brief history of stormwater management in West Park. Originally, north and south branches of Allen Creek flowed over the surface through the land that’s now West Park. In the early 20th century, Washtenaw County built drains through the park to collect stormwater, and directed the flow of Allen Creek into underground pipes. There’s also a sanitary sewer main that runs underground through the park. Hutchinson showed a map that indicated the location of the floodway and floodplain running through the park, as well as the location of the sewer main and county drains.

Over the years, conditions worsened. Deteriorating recreational facilities and uncontrolled flooding in the park led to certain areas being underused.

In 2010, the city renovated West Park, including its bandshell, basketball courts and pathways. The project also included upgrades for stormwater management, Hutchinson said. [The total project, supported in part by federal stimulus funds, cost about $4 million.]

The stormwater portion of the project included installation of some water treatment units – swirl concentrators – on the west side of the park, in the north and south branches of the Allen Creek drain. The purpose was to divert some of the water from the stormwater system, treat it, and remove pollutants before reintroducing it into the system to flow eventually into the Huron River.

Another part of the stormwater management was to remove a nominal amount of water from the stormwater pipes by disconnecting the inlets from North Seventh Street and sending some of the water back to the surface, as it had flowed historically. Water was diverted to a series of bioswales that led to wetlands and ponds as it flowed east through the park.

When construction was being completed around November 2010, Hutchinson reported, a sinkhole appeared on the west side of the park near the drain’s north branch, where the swirl concentrators were located. “These are maybe some of the things that didn’t go quite right on the project,” he said, “that we are still trying to address now.”

The contractor investigated and discovered that the lid on a swirl concentrator had caved in. Cameras were sent down into the other units and it was discovered that all four units on the north branch were in some stage of failure.

This photo, part of the meeting packet for the Jan. 24 park advisory commission, shows the installation of a swirl concentrator at West Park in the summer of 2010.

Hutchinson explained how the swirl concentrators are supposed to work. Water is diverted from the main stormwater pipe through a device called a diversion manhole, containing a 3.5-foot “weir wall” that prevents the water from flowing directly into the main stormwater system. Instead, the diverted water flows into a large cylinder, where it swirls around in a vortex. The solids in the water are forced to the center of the unit, where the velocity of the swirling is slower and the solids settle down to the bottom. The water exits into a pipe on the other side of the unit and is reintroduced into the stormwater system.

During normal conditions or a light rain, most of the water is diverted. But in heavy rainfall, only a portion of the water is diverted – the rest flows over the weir wall and continues directly through the stormwater system, without passing through the swirl concentrators.

A total of eight swirl concentrators were installed – four on the north branch, and four on the south branch. Each unit cost about $66,000, including construction. They were initially installed in June of 2010.

In August of 2010, the four units in the south branch were taken offline because of concerns that the weir wall wasn’t operating correctly, Hutchinson said. The wall wasn’t allowing higher flows to pass through the system during heavy rains. Then in November of 2010, after the swirl concentrator collapsed on the north branch, all four of those units were also taken offline. The weir wall was removed from the diversion manhole, and a bulkhead was installed to block the pipe that led to the swirl concentrators. Since then, water has flowed directly through the stormwater pipes – none of it is diverted to the swirl concentrators. The stormwater system is functioning as it did prior to 2010, Hutchinson said.

In late 2010, the city hired Orchard Hiltz & McCliment (OHM) to look into the situation. OHM began by doing a forensic investigation of the swirl concentrator failures, and determined that the lids of those units were too thin, causing the collapse. ”It was essentially a manufacturing flaw,” Hutchinson said.

OHM also reviewed the prior design of the diversion manholes and weir walls, and conducted some site-specific stormwater modeling to get an understanding of how stormwater behaves in the system. They used that information to present some ideas for improving the system, Hutchinson said. [In November 2010, city council authorized an additional $119,000 for OHM to complete these tasks. That brought total payment to OHM for the West Park project to $324,000. An August 2011 city staff memo indicated that the city expects to recover any additional costs due to the failures, either from the manufacturer or the firm that made the initial design, Beckett & Raeder Inc.]

With a failure of this magnitude there are legal issues, Hutchinson said, including disputes regarding who’s at fault – the contractor (Site Development Inc.) or the manufacturer (AquaShield Inc. and L.F. Manufacturing). He said he couldn’t discuss those issues, except to say that the parties seem to be getting very close to reaching a resolution. The legal issues shouldn’t hold up completion of the project, he said.

Next steps include refining the design of the diversion manholes and weir walls. In addition, residents have raised concerns about manhole covers being popped off during heavy rains, because of pressure from excess water in the system. So OHM is looking at redesigning the system to provide some relief options so that pressure will be eased during storms.

Another public meeting will be held on Feb. 13 at Slauson Middle School. At that meeting, city staff will review OHM’s draft design, and discuss the technical issues that led to the design, Hutchinson said.

In May and June of 2012, the manufacturer will make repairs on the units. Following that, the city will hire a contractor to make the changes that OHM proposes to the diversion manholes and weir walls. City staff hope to have that work completed by July of 2012, Hutchinson said.

West Park Update: Commission Discussion

John Lawter asked whether there are concerns that the shutdown of the swirl concentrators is affecting water detention capability, making it difficult to control floodwater. No, Hutchinson said – the purpose of the swirl concentrators isn’t water detention, but rather to improve the water quality as it flows through.

Are there problems in terms of how much water the units can handle? Lawter asked. If too much water is sent through the units, Hutchinson replied, the water will simply bypass the units and flow over the weir wall, going directly into the stormwater system. Capacity is not a concern. The redesign of the weirs and diversion manholes will ensure that the right amount of water gets in, he said.

Lawter raised the issue of basements flooding in that area, and wondered whether that problem is related to the situation at West Park. An improperly designed weir structure could cause back-ups upstream, Hutchinson said. Any design that’s installed in the future will be studied to ensure that it doesn’t cause any upstream disturbances, he added.

Sam Offen noted that this concern was raised by residents at the January public meeting on West Park. Offen agreed that the issue either needed to be resolved through the new design, or that information should be provided to residents to explain the situation.

Offen also asked how construction would affect the active areas of the park. The work will happen on the park’s west side, Hutchinson said. Access to the ballfield, bandshell and paths will be undisturbed. Kuras added that there are three entrances to the park off of Seventh Street. The north and south entrances will be closed, but the middle entrance will remain open.

Mike Anglin asked whether there was any data related to water flow through the system that was collected prior to the installation of the swirl concentrators. OHM collected flow data in the spring and summer of 2011, Hutchinson said, by putting monitoring devices in the stormwater pipes.

Anglin asked whether the city was making an effort to talk with residents whose basements have flooded. Hutchinson replied that the current project doesn’t entail working with residents. The project is specific to West Park infrastructure.

Kuras added that at the recent public forum on the West Park situation, some people brought up the issue of basement flooding. City staff knows that they need to address the broader issues related to the entire Allen Creek area upstream from West Park, she said.

Hutchinson noted that some neighborhoods – like Maple Ridge – experienced flooding in 2011. At that time, the pipes had been returned to their pre-2010 condition, he said, so the flooding they experienced wasn’t related to changes at West Park, he said.

Report on Fuller & Olson Athletic Fields

Commissioners received an update on conditions of the city’s Fuller Park and Olson Park athletic fields, which were renovated in 2009-2010. The first post-renovation scheduling of play occurred in 2011, from March through November.

From left: Jeff Straw, Ann Arbor deputy parks and recreation manager; Matt Warba, supervisor of field operations; and Jessica Black, parks and recreation customer service manager.

Jessica Black, parks and recreation customer service manager, described how the six Fuller Park fields were used during the spring, summer and fall playing seasons. [.pdf of Fuller fields layouts in 2011] She noted that the two fields at Olson Park are always used as full fields, but that some Fuller Park fields are split into half fields. There are also seasons when the fields are taken out of play and allowed to “rest.”

Black provided a breakdown of the types of users, noting that “soccer is definitely our No. 1 use.” Teams playing soccer accounted for 65% of the use of fields, 15% were lacrosse teams, and the remaining 20% was split between flag football and ultimate frisbee.

A total of 15 teams used the fields throughout 2011, including eight teams that returned from previous years and seven new teams. There were youth and adult teams, and University of Michigan club sports.

City staff had determined that 35 games per field per season was the maximum number of games that should be allowed, in order to maintain the condition of the fields, Black reported. For the three seasons in 2011, Olson and Fuller fields were used at about 79% capacity, she said. At the six Fuller fields, 679 games were played out of a possible 875. At Olson’s two fields, 175 games were played out of 210 possible games.

Jeff Straw, the city’s deputy manager of parks and recreation, briefed commissioners on revenues from the fields. Rates were set at $60 per hour for most of the full fields at Fuller and for the two Olson fields. Half-field rates at Fuller were $40 per hour. For field #6 at Fuller, the rental fee was $32 an hour for a full field, and $20 an hour for a half field. [Previously, rates ranged from $16 an hour to a high of $31.50 an hour, depending on a variety of factors, including residency (Ann Arbor residents were charged lower rates) and time of day (rates for prime time, between 4-8 p.m., were higher). PAC recommended rate increases at its January 2010 meeting.]

Based on the maximum number of games allowed, the six Fuller fields could have brought in a maximum of $70,280. But because the fields were not used at full capacity, Fuller fields recorded $54,608 in revenues during 2011. Of that, $5,400 was later refunded due to weather cancellations, Straw said.

For Olson’s two fields, $21,000 in revenue was collected, but $1,500 was refunded because of cancellations. Those two fields had the potential to bring in $25,200 in revenues, if played to capacity.

Factoring in refunds, the eight fields at Fuller and Olson had a total of $68,708 in revenues during 2011.

Total estimated expenses were $82,688. Major line items were administration and scheduling costs ($25,000), mowing ($18,368) and fertilizing/aerification/overseeding ($18,800).

Commenting on the financials, Matt Warba – the city’s supervisor of field operations – said he didn’t think it was anyone’s intent to make the fields self-sufficient. But it’s getting close, he added, and that’s encouraging.

Warba also noted that April and May of 2011 were especially rainy months – the city had to cancel play on 25 days out of a 45-day period because of rain. Warba also noted that the irrigation system at Olson failed during the summer, resulting in turf loss. That system has been repaired.

Report on Fuller & Olson Athletic Fields: Commission Discussion

Karen Levin asked how 2012 expenses are expected to compare to 2011. Warba replied that costs generally are expected to remain static.

Sam Offen wondered how revenues compared to previous years. Colin Smith, manager of parks and recreation, said it would be difficult to compare since the rates were lower in the past, prior to the renovations. He hadn’t asked his staff to bring those figures.

Gwen Nystuen asked how long it would be before the city would need to invest in another major renovation of the fields. Warba replied that it would be possible to maintain the fields without major renovations. They’re taking a cautious approach, he said, by resting fields periodically so that they can be kept in good condition. The city staff has to balance demand for the fields against maintenance.

Julie Grand, chair of the Ann Arbor park advisory commission.

Nystuen noted that because the fields are fenced in, that keeps people off when it’s raining. That was the intent, Warba said. Olson fields aren’t fenced, however, and in some cases players have jumped the fences at Fuller, he said. One field had to be taken out of play for a month because of the damage caused when people played on a field that was supposed to be closed. Warba said the city will likely hire a temporary worker next season to patrol the fields – it would be cheaper than having to repair damage to a field if players jump the fence.

John Lawter asked whether the city is meeting the need for this kind of play, or could they do more? Smith noted that the fields are at 79% capacity, so there’s space available. However, there’s more demand than capacity for prime time slots – between 4-8 p.m. Black reported that the staff has set the maximum number of games at 35 per field per season. If the city were to add more games in order to accommodate more teams, that might not ultimately meet the teams’ needs, because the condition of the fields would deteriorate. “It’s a balancing act,” Black said.

Smith said the city wants to avoid having to make another major investment in renovating the fields. If demand is high, it’s possible to look at adding fields in other parks, he added, or possibly to acquire more land for that purpose.

Julie Grand asked if the city is doing outreach to groups that might have a lower impact on the fields – sports that don’t involve as much running and kicking as soccer, for example. Black said that at this point, there hasn’t been that kind of outreach.

Gwen Nystuen called the overall report encouraging.

Communications: Allen Creek Greenway, Leslie Science Center

Every meeting includes opportunities for public commentary and communications from commissioners and staff. No one spoke during either of the slots for public commentary at the Jan. 24 meeting.

Communications: Allen Creek Greenway

Gwen Nystuen brought up the issue of the Allen Creek Greenway. She noted that mayor John Hieftje had mentioned there might be action taken soon on the city-owned 415 W. Washington property, which has been identified as a potential part of a greenway. He’d made these comments at the Jan. 23 city council meeting. She wondered if there was any additional information about that.

[Hieftje had indicated that talks were continuing with the group that had been formed to look at the city-owned 415 W. Washington lot. The council passed a resolution giving direction for the effort at its Feb. 1, 2010 meeting, nearly two years ago. The resolution calls for the arts and greenway communities to lead fundraising and development of a vision for the parcel’s use. The site, across from the YMCA, is currently providing revenue to the city as a surface parking lot. It was previously the city’s maintenance yard. At the Jan. 23, 2012 council meeting, Hieftje said the group continues to meet – the biggest challenge remains the building. He said a report on the status of the project would be given at the end of February.]

Christopher Taylor, an ex-officio member of PAC who also serves on city council, said he didn’t have any further information at all. Nystuen then reminded commissioners that the greenway is one of PAC’s priorities. The City Apartments project at First and Washington, by the developer Village Green, is moving ahead, she said. That residential development will include parking spaces, she added, which will free up the need for spaces at the city-owned First and William surface lot that’s located in a floodway. That lot could become part of a greenway, she observed.

Park commissioner Gwen Nystuen and city councilmember Mike Anglin, an ex-officio member of the commission.

The time has come for PAC to actively pursue the greenway, Nystuen said, adding that the city council passed a resolution recently in support of a greenway.

Colin Smith, the city’s parks and recreation manager, noted that a council resolution was passed on Aug. 4, 2011 expressing general support for the idea of a greenway. There have been conversations, he said, about applying for a grant from the Michigan Dept. of Natural Resources Trust Fund, to turn the 415 W. Washington site into a park. The city staff is looking into that. The process would be similar to the way that the trust fund application for the skatepark had been handled, Smith explained. Staff would first come to PAC for a recommendation to apply. That recommendation would be forwarded to city council, which would need to approve the application.

Smith noted that one issue for the 415 W. Washington property is that it’s located in a historic district – the Old West Side. So in addition to PAC, the city would need a recommendation from the historic district commission too, he said.

Finally, Smith reminded commissioners that the parks, recreation and open space (PROS) plan, which PAC approved, recommends that the first action should be development of a master plan to guide the creation of a greenway. That point bears consideration, he said.

Nystuen responded by asking what PAC could do to move this process along. This year her term on the commission ends, she said, and the greenway has been a priority for her for both of her terms on PAC. That’s why she feels some urgency about this issue, she added.

What PAC decides as a body is up to commissioners, Smith replied. They can give direction to develop a greenway master plan, or tell staff to move ahead on the grant application before a master plan is developed. Nystuen asked how other commissioners felt – should they put forward a resolution?

Mike Anglin, a city councilmember who’s a non-voting ex-officio member of PAC, noted that the city’s environmental commission – on which he also serves has previously served – sometimes deals with issues related to parks. Perhaps a subcommittee of the two commissions could be formed to discuss the greenway, he said. There’s federal funding available for water management, he said, which might be one aspect of the greenway. Anglin also noted that the arts community has been interested in that site – they should be included in the dialogue, too.

There are several interested parties, Smith said – parks, the county drain commissioner, the University of Michigan, the Ann Arbor Downtown Development Authority, the railroad owners, the Arts Alliance and others. That’s why having a master plan would be useful.

Julie Grand asked about a timeline for the grant application. It’s due April 2, Smith said. That means it would be necessary to secure a PAC recommendation in February, and city council approval in March. It’s also unclear how the historic district commission would fit into this process.

No doubt there’s strong interest in the community, Smith said. But it’s uncertain how to manage the project at this point. He noted that a task force had been formed in 2007 to evaluate development of a greenway that might incorporate the 415 W. Washington site as well as city property at 721 N. Main and First & William. The group couldn’t come to a consensus for the best use of 415 W. Washington, he said, so no decision was made. It seems like a public dialogue is needed to figure out the best option, he said.

Nystuen said she wanted to point out that the near-downtown area on the city’s west side has a shortage of green space. New residential developments will be bringing hundreds of young people downtown, so there will be an increased interest in recreational areas, she said. It makes sense to move forward with a greenway adjacent to downtown. Nystuen said it sounded like the best approach would be to put together a resolution for PAC’s February meeting.

Smith said he’s still waiting on direction regarding whether to apply for the grant. If he gets that direction, then of course the staff would bring a resolution to PAC, he said. Separately, PAC can do what it wants regarding the greenway – that’s not for him to say, Smith told commissioners.

Communications: Leslie Science & Nature Center

At the beginning of the Jan. 24 meeting, commissioner Sam Offen introduced the new executive director for the Leslie Science & Nature Center, Susan Westhoff. [Offen is a board member of the center.]

Sam Offen, an Ann Arbor park advisory commissioner, and Susan Westhoff, executive director of the Leslie Science & Nature Center. Offen also serves on the center's board.

Offen said that Westhoff started about a month ago and is already doing an excellent job. He noted there had been a recent public meeting at the center to discuss a master plan for pedestrian access there. [The center was previously part of the city's parks system, but was spun off as a separate nonprofit in 2007. The city continues to own the center’s property and buildings.]

Westhoff spoke briefly to commissioners, noting that the center and the city had a long history. She said she’s been working in nonprofit administration for about 15 years. She grew up in Canton and graduated from the University of Michigan. Her first nonprofit experience was at the University Musical Society, and she said she’s glad to be back in Ann Arbor.

Westhoff said she’d be happy to share the plans for the pedestrian pathway improvements that are being developed. Among other things, it will make paths to the center’s raptor enclosures ADA compliant. She also noted that the center has many great public programs, and highlighted the Feb. 12 “Hoo’s Your Valentine?” event that features the center’s barn owl.

Julie Grand, PAC’s chair, thanked Westhoff for coming and said she looked forward to collaborating.

Present: Doug Chapman, Julie Grand, Karen Levin, Gwen Nystuen, John Lawter, Sam Offen, councilmember Mike Anglin (ex-officio), councilmember Christopher Taylor (ex-officio). Also Colin Smith, city parks manager.

Absent: David Barrett, Tim Berla, Tim Doyle.

Next meeting: PAC’s meeting on Tuesday, Feb. 28, 2012 begins at 4 p.m. in the city hall second-floor council chambers, 301 E. Huron St., Ann Arbor. [confirm date]

The swirl concentrators, which help remove suspended solids from water entering the city’s stormwater system, were a part of major renovations to the park’s landscaping and draining systems. Federal stimulus funds helped pay for much of the work.

A recent city staff memo indicates that the city expects to recover any additional costs due to the failures – either from the manufacturer or the design firm. Replacement of the swirl concentrator units is not expected to be complete until early in the 2012 construction season, with the park restored to full public use at that time.

Meanwhile, the park enjoyed a grand re-opening earlier this summer, and is accessible for all functional purposes, including performances in the bandshell.

Two theater groups are sharing the stage this summer: Blackbird Theatre and the Penny Seats Theatre Company.

This weekend wraps up the Penny Seats production of “Goodnight, Desdemona (Good Morning, Juliet).” Performances still remain on Saturday and Sunday (Aug. 13-14). The Chronicle shares a few images from the comedy after the jump.

Before the meeting, park advisory commissioner John Lawter receives the final draft of the PROS plan from park planner Amy Kuras. Looking on is commissioner Gwen Nystuen. (Photos by the writer.)

Before approving the plan, the commission heard public commentary on the issue, as well as an update from park planner Amy Kuras about how some concerns had been addressed in revisions to earlier drafts. Later in the evening, the city’s planning commission also signed off on the plan. The PROS plan is set to come before the city council on March 7.

Heard during public commentary was criticism of the PROS plan for language it contains describing public-private partnerships for park services. One example of a potential partnership arose later in the meeting, when parks and recreation deputy manager Jeff Straw outlined a request for proposals, currently in draft form, that would explore interest from vendors in providing food concessions at park facilities.

The commission also approved a recommendation to raise fees slightly at the city’s golf courses for some items. Consideration of the fee increase came prior to the year’s regular budget decisions, so that the city council can consider and give final approval to the fee increases before the city’s golf courses open for play in the spring.

Also at the meeting, parks and recreation manager Colin Smith reviewed the parks budget presentation that had been made at a Jan. 31, 2011 city council work session. Smith also gave commissioners an update on two items concerning Argo Dam. He described how intake lines for a well that’s used for measuring water levels in the pond – so that the dam gates can regulate that level – had become clogged, and had ultimately required hiring a diver to unclog one of them.

The second Argo-related item was an update on the planned bypass channel which was recommended by the city’s park advisory commission and approved by the city council last year. Insurance issues are still being worked out with the contractor, Smith said, and construction will not start as early has had been hoped. Construction is not expected to be complete before the end of the construction season – in November.

Commissioners also agreed that before the city council approves the operating agreement between the city and the University of Michigan for the planned Fuller Road Station, they would like an opportunity to review that agreement.

At the meeting, commissioners also heard about a setback in a construction project that’s already nearing completion – renovations to the drainage system in West Park. Eight swirl concentrators were installed as a part of the project – four near the north Seventh Street entrance and four near the south entrance on Seventh. Craig Hupy, head of systems planning for the city, reported that four out of the eight swirl concentrators were in some state of failure, and that one of the four had experienced a catastrophic failure. The other four are also suspected to have problems.

West Park Swirl Concentrators: Catastrophic Failure

During the 2010 construction season, the city undertook major renovations to the drain system in West Park. Craig Hupy, head of systems planning for the city, seemed glum as he gave an update to park commissioners about a setback in the work. Most of the work in the park is complete, he said. The work around the park amenities, like the play area and the bandshell, is complete. The plantings for the wetland basins are not yet done, because spring is a better time to set them out.

View looking northeast from Seventh Street at the edge of West Park: site of the failed swirl concentrator. The backhoe had departed by the time this photograph was taken.

He began the discouraging part of the report by describing how there is currently a big yellow backhoe at the northwest end of the park on Seventh Street. The presence of the backhoe, he said, was due to a “catastrophic failure” in the new stormwater infrastructure that had been installed. During the construction work in the park, Hupy said, changes were made to the drain system. Eight swirl concentrator units – which help remove solids in the stormwater stream – had been installed as part of the drain system improvements, he explained. Four units were installed near the north Seventh Street entrance of the park and four units were installed near the south entrance on Seventh.

He told commissioners that one of the units on the north end had failed catastrophically and that the three other units on the north end were in some state of failure. They also suspect that the four units on the south end may be suffering similar failures. It’s not clear what caused the failure, Hupy said – the city has used such units at various other locations around the city. There are lawyers and engineers involved, he said, so there’s not yet any public statement that’s available.

Hupy also described how during heavy rains last year, the side of Seventh Street opposite the park had experienced a backup of water. It’s not completely clear, he said, whether the water backup was due to the construction configuration, or if it was due to changes in the park drainage system. The intent of the project, Hupy said, was of course to improve the drainage, not make it worse.

The use of the park amenities like the bandshell or the play area, he said, should not be affected by the work that will be required to put the swirl concentrators back in working order. They’d need to be dug up and rehabbed or replaced. Hupy indicated that the city hoped to be able to use the same source of funds that had paid for the project – a combination of federal stimulus and revolving loan – to effect the repairs.

Commissioner Tim Berla asked what exactly “failure” meant. Hupy told him the unit simply collapsed – nobody was hurt, though. Sam Offen wanted to know how long the repair would take – weeks or months? Hupy estimated that it would take until the end of the construction season – November.

Commission chair Julie Grand wanted to know what the implications for flooding are, with the swirl concentrators out of commission. Hupy explained that the walls directing water into the concentrators have been removed. The stormwater flow into the grates in Seventh Street was converted to overland flow through the park as a part of the project, he continued, so that should give an improvement in the stormwater management.

PROS Plan

The Parks and Recreation Open Space (PROS) plan, which provides an inventory, needs assessment and action plan for the city’s parks system, is updated every five years. The updated document is required by the state in order for the city to be eligible to apply for certain grants. The process – led by park planner Amy Kuras – began in late 2009. The city’s park advisory commission was scheduled to vote on the plan at its Jan. 18, 2011 meeting, but that vote was postponed, because the time for public input had been set to last through Jan. 24.

PROS Plan: Public Comment

Dorothy Nordness led off public commentary by citing three areas of disappointment with the draft PROS plan. First, she cited a lack of commitment to a downtown greenway in the plan. It’s important to think well into the future, she said, not just about how to get through the next year or two. She said she grew up in Minneapolis, where planners had thought ahead and the city had developed a park system that led people to love it at first sight. She challenged Ann Arbor to do the same. Her second criticism was that Ann Arbor settles for parks without a special designation as “parkland” with accompanying protective language preventing sale or lease of the land. The general “public land” designation used by the city is not sufficient to prevent the altered use of parkland. She gave as an example the Fuller Road Station site, which she called “under siege.”

As her time elapsed, Nordness addressed the language in the plan dealing with public-private partnerships, saying that any such partnerships needed to have periodic evaluation. [.pdf of remarks by Nordness]

PROS Plan: Staff, Commissioner Comment – Public-Private

Park planner Amy Kuras summarized for commissioners a series of revisions she’d made to the plan since they’d seen it at their January meeting. Highlights included:

• Section I: open space inventory now includes non-city open space; language about the city’s transportation plans and its open space millage has been added.
• Section II: language has been added to include relationships between the parks system and independent nonprofits like Leslie Science and Nature Center.
• Section III: information about the FY 2011 budget has been moved to an appendix; information on budget trends has been added.
• Section IV: references to the “drain commissioner” have been updated to “water resources commissioner;” the font size for maps had been increased; the fact that Narrow Gauge is a nature area has been made clear; the relationship between Dicken Woods and the schools has been made clear.
• Section V: language has been added about how park acquisition standards are developed; the section on downtown parks has been expanded; information on the city’s parkland charter amendment has been added; a map showing just the greenbelt boundary area has been replaced with one showing the specific properties protected by investments from the greenbelt millage.
• Section VI: projects that are now known will be completed are described that way (like the Argo Dam bypass channel); a section on public-private partnerships has been added, which includes language about evaluating the risks of such partnerships.
• Section VIII: a section about the greenway has been added, but no map has been included, because it’s not yet a part of any of the city’s master plans.

When Kuras finished ticking through the revisions, commissioner Tim Doyle wanted to know what the next step is. Kuras explained that later that day the planning commission would vote on the plan. Then it would be forwarded to the city council for their consideration on March 7. In connection with grant applications, the state’s deadline for final approval of the PROS plan, Kuras said, is actually March 1. She’s received an extension from the state, and later that evening she’d be FedEx-ing the plan to the state office, with a note saying that it is stilling pending approval by the city council.

The city will still be inside a different deadline for expiration of the current plan, which is April 1, Kuras explained.

Commissioner Gwen Nystuen wanted to know if there were any grants the city wanted to apply for that could be affected by not having the PROS plan approved. Yes, said Kuras, giving the Gallup Park canoe livery and a skatepark proposal as examples.

Mike Anglin, one of two city council ex-officio members of PAC, expressed concern about the exploration of public-private partnerships mentioned in the plan. Any RFP that would include divestment by the city in its parks should include input from PAC, he said. Anglin alluded to the RFP for the privatization of Huron Hills golf operations as an example of inadequate input from the public and PAC.

Kuras clarified that the added language she’d mentioned about public-private partnerships simply reflected the feedback from the planning commission for the section of the PROS plan that summarizes their input as a focus group. That section reads:

4) Staff should explore all opportunities to generate revenue, including public/private partnerships. A balanced view must include all possible risks inherent with acceptance of private funding.

Colin Smith stressed that inclusion of the concept of public-private partnerships is not new to the revised version of the PROS plan that PAC was being asked to consider. It’s been included in previous versions, and it’s also been emphasized that the risks must be balanced with the benefits.

Mike Anglin, an Ann Arbor city councilmember representing Ward 5 who also serves as an ex-officio member of the park advisory commission.

Smith addressed Anglin’s specific complaint about the RFP for Huron Hills golf operations by pointing out that the proposal had been discussed by the city’s golf task force and also by PAC itself. It had been a very public process, Smith said, and feedback from the public had been incorporated into the RFP.

The idea, said Smith, is that the city needs to look at opportunities for public-private partnerships, which is not to say that the city must take every one of those opportunities.

Commission chair Julie Grand also took exception to Anglin’s description of the Huron Hills RFP process, saying that she’d been present on the golf task force representing PAC for the RFP discussions, and had represented PAC at the interview with Miles of Golf, a local business that had responded to the RFP. She concluded that the Huron Hills RFP illustrated well that the city had weighed the risks and the benefits – the city ultimately rejected the Miles of Golf proposal.

Smith then gave various examples of public-private partnerships in the park and recreation system. Bryant Community Center and Leslie Science and Nature Center are operated by independent nonprofits, he said. The city’s recent promotion with Stonyfield Farm yogurt is another example, he said, as well as Zingerman’s products sold at Gallup canoe livery.

Gwen Nystuen said she thought Anglin’s point was important. She’d heard comments that the inclusion of public-private partnerships in the PROS plan made it sound like there was pressure to make money from the parks. Proposals like parking cars at Allmendinger and Frisinger parks on football Saturdays and the Huron Hills RFP were different from smaller, less permanent issues like concessions in the parks. She was concerned that permanent changes be treated differently from more minor decisions. Nystuen felt that PAC should have been more involved in the Huron Hills RFP than they were.

Smith responded to Nystuen by saying that the reality of the city’s situation is that it’s in a hard spot. They need to ask the question about whether to have a public-private partnership – even though they might answer, “No.” They need to look under every rock, he concluded.

Commissioner Tim Berla gave the city’s farmers market as another example of a public-private partnership. He noted that there had been a lot of upheaval in the community about the Huron Hills proposal, but in the end, nothing happened. It’s always important to weigh whether a proposal is good for the community or rather is simply good for some business. That could be done, he felt, without trying to impose a lot of rules for how public-private partnerships had to operate. The important thing is to make sure everything in the decision-making process is transparent, he said. He said the Huron Hills proposal showed that they’re doing a good job of that.

The discussion on the PROS plan concluded with a clarification from Smith, in response to some questions from Nystuen, about some budget information included in the plan. Administrative costs are not included in the costs of operating individual facilities, he explained.

Outcome: The park advisory commission voted unanimously to recommend adoption of the PROS plan.

Golf Course Fees

Before the commission was a recommendation to raise certain fees at the city’s golf courses. Power golf cart rentals for 9 holes at Leslie Park and Huron Hills would increase from $7 to $8; for 18 holes, the rental fee would increase from $13 to $14. City staff estimate the increases would generate $25,000 in additional revenue per season.

Weekend fees for 9 and 18 holes at Leslie Park golf course would increase by $2 and $1, respectively, and the twilight fee would increase to $16, up from $15. These increases would generate an estimated additional $12,500 in revenue per season. In addition, the commission approved raising the senior citizen qualification age to 59 for the 2011 season. That’s part of a consultant’s proposal to incrementally increase the qualification age from 55 to 62 by adding one year to the minimum age annually.

By way of introducing the proposed fee increases, Colin Smith told commissioners that the idea was to make sure that fees are still in line with other courses in the area. The fee increase for 18 holes of golf on the weekend would put Leslie at $30, Smith said, which is what the Pierce Lake course charges. The proposed increases had received unanimous support from the city’s golf task force two months ago, but they had not come easily to that conclusion.

Smith explained that the fee increase was coming to PAC in advance of the regular budget, because they wanted to get the fee increase in front of city council for final approval before the courses open in the spring.

Commissioner David Barrett got clarification that the budget impact was expected to be an extra $25,000 annuallyl from cart rentals and an extra $12,500 annually from the increase in fees for play. Commissioner Karen Levin wanted to know how often the fees were set. Smith explained that they’re reviewed every year to make sure they are in line with the competition.

Commissioner Tim Doyle wanted to know if there was a difference in price between city residents and non-city residents. Smith told Doyle that there was no difference. A recommendation from Golf Convergence had been to eliminate the different fees. Especially for Leslie, Smith said, differentiating between residents and non-residents on price was perceived negatively. It didn’t seem to make sense to pay more because you drive farther to get there.

Doyle wondered if there might be an impact on season pass sales if the price per round went up. Smith allowed that the fee increases could be a very minor additional economic incentive to purchase a season pass, but he did not think it would amount to more than a couple of extra passes sold.

Commissioner Sam Offen asked if there was any kind of combined season pass for various area municipal golf courses. Smith said there was not a season pass available, but that there was discussion of trying to coordinate marketing efforts.

Smith also clarified that once fees are set, staff has the flexibility to be creative about creating “specials.” He gave as an example a special deal where golfers could play 18 holes of golf for $18 if they started before 8 a.m. The tee timesheet between 7-8 a.m. is now full, he reported.

Mike Anglin wanted to know what the expected number of rounds would be at Huron Hills for the upcoming season. Smith put the numbers in perspective: In 2007, Huron Hills had seen 13,000 rounds played. Last year that number had risen to 22,000 rounds. This coming year, he’s hoping for 25,000 rounds, he said.

Commission chair Julie Grand asked for some explanation for the use of full-time year-round staff for the golf courses. Smith explained that the analysis of the previous season and planning for the upcoming season is done during the time the courses are closed. Smith said it’s not just the golf task force that has been instrumental in improving the number of rounds played over the last three years at the city’s golf courses. He attributed a lot of the success to the efforts of the city’s full-time golf course staff.

Smith also pointed out that the golf courses are not unique in having year-round staff, despite being open only part of the year. Canoe liveries follow that staffing strategy as well, he said. It’s during the off-season that programs are upgraded, and trends are studied. During the season, there’s only time to implement what has been developed during the off-season.

Commissioner Gwen Nystuen was curious to know if the off-season planning by the golf staff included use of Huron Hills for winter activities like cross-country skiing. Smith said he’s asked staff to contact local businesses that sell cross-country skis and snowshoes to begin a conversation about some kind of partnership, but indicated that he was not optimistic that it would generate revenue.

Outcome: PAC voted unanimously to recommend raising some of the fees associated with the city’s golf courses.

Budget Review

On the commission’s agenda was an update from parks and recreation manager Colin Smith on the parks and recreation planned FY 2012 budget. He reported from the city council’s budget work session on Jan. 31, 2011, which focused on the community services area, of which parks and recreation is a part. [.pdf of parks and recreation budget impact sheet]

Budget Review: Public Comment – Golf Courses

A large part of the discussion at the city council’s budget work session focused on options for the Huron Hills golf course. [.pdf of staff memos on golf course options and a $287,000 general fund supplement to the parks] At the park advisory commission meeting on Tuesday, commissioners heard public comment from two speakers who addressed the topic of Huron Hills golf course.

Nancy Kaplan told the commissioners that she was pleased with the apparent consensus reached by the city council at their Jan. 31. 2011 budget work session that Huron Hills would continue to be used as a park and that it also seemed agreed that the best economic use of the land is its current use – as a golf course. She expressed some concern about the fact that the city employs full-time, year-round employees for Huron Hills when the golf course is only open for part of the year. She suggested exploring additional opportunities for recreation at Huron Hills during the winter – ice-skating, cross-country skiing and snowshoeing. She stressed that she was pleased that Huron Hills remains parkland.

Ann Schriber told the commissioners that she was pleased that the Miles of Golf proposal had been turned down. She described how there are more than 100 people involved in the effort to make sure that Huron Hills is kept as parkland, yet “nobody has ever asked us” for their input on ways to ensure its future as parkland. She said the city had spent $50,000 on a consultant and that her group, Ann Arbor for Parkland Preservation, had spent $10,000. With $60,000, she said, surely they could come up with something.

Budget Review: Staff, Commissioner Discussion

Smith laid out for the commission the main points of the city council work session presentation:

• Ways that parks and recreation would be meeting its roughly 2.5% reduction target. [Energy savings in FY 2012 and increased revenues due to the construction of the Argo Dam bypass channel, in FY 2013]
• A question about whether to continue a $287,000 supplement to the parks and recreation budget, which began in FY 2008 amid controversy over the interpretation of an October 2006 city council resolution about the administration of the parks capital improvements and maintenance millage.
• Options for the future of Huron Hills golf course.

[For detailed coverage of the work session itself, see Chronicle coverage: "Ann Arbor 2012 Budget: Parks, Plans, People"]

With respect to the $287,000 parks supplement, Tim Berla recalled how the city’s chief financial officer had addressed PAC in 2007 in preparation for the FY 2008 budget planning and had explained how the parks budget does not increase at as high a rate as, for example the police department, which has a greater percentage of its costs due to personnel. He also recalled how part of the explanation for the apparent disparity in parks funding that year, compared to other parts of the budget, was related to the idea that a department can’t count savings for activities that had been discontinued.

In broad strokes, the controversy that resulted in the $287,000 parks supplement involved the language of the October 2006 resolution, which indicated that parks would be treated the same as other parts of the budget with respect to any increases or decreases.

Before the meeting started, Colin Smith, manager of parks and recreation for the city Ann Arbor, distributes written material to commissioners.

Smith told Berla that an accounting of how the parks budget had been treated the same as other parts of the budget since 2007 was now prepared in draft form. Berla had requested a report on that at PAC’s Nov. 16, 2010 meeting.

Commissioner David Barrett recalled that he’d been there during the 2007 “kerfuffle” and that the concern had been that the newly-passed millage was being swallowed up by reductions of general fund support to the parks. He gave credit to then-councilmember Bob Johnson for working it out. There’d been a feeling that the public voted and was then being hornswoggled, Barrett said.

Smith said that the city’s accounting at the time had been correct, but that perceptions had been otherwise and so the $287,000 had been supplemented to make the parks whole.

Summarizing the apparent council consensus that Huron Hills would remain a golf course for the next two years at least, Smith said that the cost to the city to use the property as a golf course was in line with, if not less than, any non-golf uses.

Argo Dam Update: Bypass, Funding, Water Levels

Parks and recreation manager Colin Smith gave commissioners updates on two different Argo Dam-related issues. The first was news that the hoped-for construction start for the Argo Dam bypass channel would not be realized. The city was meeting with the contractor and is still working out insurance issues, he said. It will take until the end of the 2011 construction season to complete the work, he said.

In response to a question from John Lawter, Smith said that the issue of the parks responsibility for funding dam maintenance would be addressed during the budget process. [At issue is whether the funding for dam maintenance at Argo is appropriately taken from the city's drinking water utility fund, even though Argo is considered a recreational dam. The city council debated the issue most recently at its Nov. 15, 2010 meeting, when the council approved the construction of the bypass channel at Argo, which will eliminate the need for canoeists to portage around the dam.]

Smith also reported that near Argo, intake lines for a well that’s used for measuring water levels in the pond – so that the dam gates can regulate that level – had recently become clogged, and had ultimately required hiring a diver to unclog one of them. When the water level in the well is low, the dam gates close in order to raise the level. When the water level in the well is high, the dam gates open to lower the level. If the intake pipes – which are between 1.5-2.0 inches in diameter – become clogged, the water level of the pond cannot be properly regulated.

The city’s first attempt to clear the lines was to use compressed air to blow out the lines. Ultimately a diver had to be hired to dive into the water, Smith said, to clear one of the lines. Work on the other line, which is a backup, will wait until warmer weather. All the dams have such regulators, he said, and they do become clogged from time to time. Clearing out the lines is a routine event, though he allowed that hiring a diver in the middle of winter made it “non-routine routine.”

Park Concessions RFP

Jeff Straw, deputy manager of parks and recreation, briefed commissioners on a draft of a request for proposals (RFP) he’s working on for concessions in the city’s park’s facilities. In light of the concerns about public-private partnerships that had been expressed earlier in the meeting, Smith playfully asked commissioners to “be kind” to Straw.

By way of backround, Straw told the commission that a few years ago the city had discontinued most of the concessions in the parks. They’d instead provided vending machines. That had allowed staff to focus on programs and services. Concessions weren’t completely eliminated, he explained, giving the golf courses, canoe liveries and Veteran’s Memorial Park ice rink (but not the pool) as examples.

The staff has heard feedback from park users that it would be nice to have concessions available. So the RFP would be to provide concessions. Straw said that except for the Veterans Memorial Park pool, the locations where the city is soliciting concessions proposals have dedicated space and facilities for concessions – it would be a win-win, he said. There would be no expense to the city. He hopes to be able to issue the RFP in the spring, and if there are responses that are agreeable, the city might be able to implement concessions operated by a private vendor starting with the new fiscal year, which is July 1, 2011, if not sooner.

Straw emphasized that the idea is not to commercialize the parks – it’s to provide a service that park users want. For a swimmer who wants to spend the afternoon at the pool, to get food they’d have to leave and come back. The RFP would include Buhr Park ice rink and pool, Veterans Memorial Park ice rink and pool, Fuller Park pool and athletic fields, and the Southeast Area Park.

They would entertain proposals involving “mobile carts,” too, he said. [In subsequent commissioner deliberations, they clarified that this did not mean that a vendor would be wandering up to park users soliciting purchases, but rather it means something akin to a food cart on the street – it'd be hauled to a location, and then at the end of the day would be put away.]

The city is not looking to discontinue the vending machines, because concessions might not be staffed for the entire time a facility is open, Straw explained. The RFP will include an expectation that some kind of sponsorship donation be made for exclusive use of the facilities and that donation would be put towards the city parks scholarship program.

Sam Offen said he thought issuing the RFP for concessions is a great idea. In response to a question from Offen, Smith said that he thought the city stopped selling concessions at its parks sometime around 2003 or 2004. He said when it was done by the city, it simply wasn’t done very well.

Offen wanted to know if someone responding to the RFP had to bid on all the locations – yes, said Straw. But if they don’t have success with that approach, they might have to try something else. Offen was also curious to know what the financial arrangement with a vendor would be like. Straw said that under the RFP, the vendors would make some kind of proposal – a percentage of gross, percentage of net, flat rental or sponsorship.

In response to another question from Offen, Straw said that the RFP does not provide any preference for Ann Arbor businesses right now.

Gwen Nystuen called offering concessions a good idea – it’s a nice thing that people enjoy, she said. She wouldn’t want to limit it just to vendors who would handle all locations. She said she liked the idea of a local business handling it.

Christopher Taylor, one of two city council ex-officio representatives to PAC, kidded Straw about what he meant by “no expense to the city.” Straw allowed that there would be some cost of utilities like gas, electricity and water. But there would be no inventory, supplies or staff costs, he said. Taylor confirmed further with Straw that utilities could not be charged to vendors because they’re not separately metered. There would be some amount of oversight and compliance, but basically whatever revenue the city realized would be “all margin.”

Tim Doyle wanted to know if the impact of clean-up costs had been factored into projections. He figured there would be some additional cost to cleaning up after park users who used the concessions. He said his first thought was to require that soda only be sold in cans with a deposit to ensure that someone had an incentive to go around and pick them up – but it had quickly occurred to him that there were many other kinds of trash that the strategy would not cover. He suggested that the RFP include a provision that any contract awarded to a vendor have a clause requiring a “re-look” after a certain period of time.

John Lawter suggested that recycling be thought about in connection with the clean-up issue. Doug Chapman drew out from Straw the fact that vendors would need to pass a health code inspection.

Doyle suggested that vendors would need to be sensitive to price – people might be turned off if costs were prohibitive. They’d hear complaints if a vendor were charging $7.50 for a hot dog, he said. Straw assured Doyle that the city wanted to make sure there are affordable options. Straw also said that they wanted to make sure there are healthy options, as well.

Julie Grand expressed some concern about the idea of mobile concessions, saying that it’s a challenge as a parent when options are presented in a manner where they are “in your face.” Straw clarified that once the concession is set up on a given day, it would not move around.

Straw concluded by saying he thought the RFP would be issued sometime in the month of March.

Fuller Road Station

During the slot for commissioner-proposed business, Gwen Nystuen expressed concern about how Fuller Road Station would be moving ahead. She reviewed many of the issues associated with the project, chief among them, the fact that the location – which is currently a 250-space surface parking lot – is city parkland. The city-university project would include around 1,000 total parking spaces as well as bus bays in its first phase and is later expected to include a train station.

Despite what the name plate says, this is park advisory commissioner Gwen Nystuen.

A point of  agreement among commissioners was the importance of the resolution that they’d passed at their June 15, 2010 meeting about the Fuller Road Station project. [Chronicle coverage: "Park Commission Asks for Transparency"]

Colin Smith told commissioners that currently the city attorney’s office is still working on the Fuller Road Station operating agreement between the city and the University of Michigan. He said he did not think, as Mike Anglin suggested, that it was on the agenda for the city council’s second meeting in March.

Commissioners made clear they want to make sure they have a chance to review the operating agreement before the city council votes on it. David Barrett drew an analogy to pouring cement on a deal – it shouldn’t begin to harden before PAC can have an impact on it.

Nancy Kaplan returned to the podium at the conclusion of the meeting during the second opportunity for public comment, and said she’d attended all the public meetings on the Fuller Road Station, and that the public who’d attended had almost universally objected to the station. She told commissioners that a group of UM graduate students is also opposed to building the station.

Present: David Barrett, Doug Chapman, Tim Berla, Tim Doyle, Julie Grand, Karen Levin, Sam Offen, Gwen Nystuen, John Lawter, councilmember Mike Anglin (ex-officio) , councilmember Christopher Taylor (ex-officio). Also Colin Smith, city parks manager.

Next meeting: PAC’s meeting on Tuesday, March 15, 2011 begins at 4 p.m. in the Washtenaw County administration building boardroom, 220 N. Main St. [confirm date]

Pat Cody looks a bit cold working on the drilling rig in the Pioneer High School field diagonally across from Michigan Stadium.

When Steve Bean filed a Stopped. Watched. item reporting a drilling rig putting holes in the Pioneer High School lawn, The Chronicle sprang into action. We figured we already knew what it was about: a project to improve the water quality of the Allen Creek watershed, which the Ann Arbor city council had approved at its Nov. 17 meeting. Just the same, the possibility of a giant drill in action is hard to resist.

Bean’s description was dead-on. When The Chronicle arrived on the scene, Pat Cody was leading a three-man crew drilling a total of eight holes to a depth of 40 feet. They were working on the fifth one. The point of these bores was to find out exactly what was down there in order to make decisions about optimal placement of the giant tanks that will eventually be buried underground at the site.

When The Chronicle made phone contact with Harry Sheehan, environmental manager with the Washtenaw County Drain Commissioner’s office, we reported to him that during the brief time we watched the drilling in action, it seemed like Cody’s team was coming up with sand, sand, sand. Sheehan said that was good news, because some previous test bores under the Pioneer parking lot had found clay, clay, clay.

Sheehan also gave us some additional detail on the Pioneer project, which he’d presented to the Ann Arbor Public Schools Board of Education at their regular meeting just two days prior on Dec. 3.

Why was sand good news? It has everything to do with what the tanks are for. Storm water that is currently carried via 42-inch and 54-inch underground pipes to Allen Creek (which is also an underground pipe, despite the nomenclature) will be diverted to holding tanks to be installed at the Pioneer location. And if the tanks can be located over a sand seam, the water diverted to the tanks for treatment can be allowed to infiltrate through the existing sand substrate – allowing nature’s own filters to do their work – with no additional engineering of the soil required.

Xs and red dots marked the spots where Cody and his team were drilling.

Treatment? What sort of treatment does the storm water need? The Huron River has too much phosphorus, and the project at Pioneer is part of an attempt to respond to a mandate from the state to reduce phosphorus loading in the Huron River by 50%. Part of the strategy is to remove phosphorus from the Allen Creek watershed, which feeds the Huron.

The phosphorus to be removed is in solid suspended form, and the amount of phosphorus correlates highly with the amount of total suspended solids (TSS). So the actual treatment process doesn’t target phosphorus per se, but rather all suspended solids. It’s a purely mechanical process that uses swirl concentrators, as opposed to a chemical reaction. When the water is spun, the suspended solids concentrate in the center of the swirl. When velocity is reduced to zero, additional settling out of solids occurs. All this solid matter will need to be sucked out periodically with a vacuum. The swirl concentrators will be located out of view, under the surface in a manhole.

Where the manholes and the tanks will be located has not yet been determined, but Sheehan presented two detailed options to the school board last Wednesday. Option 1 would put two tanks – one connected to the 42-inch pipe and the second connected to the 54-inch pipe – in the grassy field in the northeast corner of the Pioneer property, just southwest of Michigan Stadium. Option 2 would also include two tanks, one for each pipe, but would put the tank for the 54-inch pipe under the paved parking lot just to the south of the grassy field.

The sections of the bore that emerged while The Chronicle was watching were filled with sand, which was good news to Harry Sheehan.

Location is not the only difference between the two options. Because of the added cost involved in dealing with the unfavorable soil conditions under the parking lot, the 54-inch pipe on Option 2 would divert to a tank about half as big as on Option 1. Tank sizes for the 54-inch pipe on the two different options would be 196,000 cft on Option 1 versus 100,000 cft on Option 2. In terms of gallons, that’s around 1.4 million versus 0.7 million gallons.

Another difference between the two options is the possible construction schedule. On Option 1, the main constraint is the UM football season – the grassy area is used for RV parking and tailgating. So construction could begin after the last football game of the season in November 2009. For Option 2, construction on the parking area location could proceed only during summer months when school is not in session. Key dates coming up for the project:

• Jan. 20, 2009: Prepare draft plans and specifications in partnership with AAPS for review by the Michigan Department of Environmental Quality (MDEQ)
• March 27, 2009: Continue to work with AAPS to revise plans for final approval by MDEQ
• June 22, 2009: Loan closing ($4.4 million)
