Minutes for Trustee Special Meeting – August 1, 2014

The Combined Lake Delhi Recreational Facility and Water Quality District

Board of Trustees Meeting

Friday, August 1, 2014– 3:00 pm.

Heritage Bank Conference Room

Delhi, IA

A special meeting of the Combined Lake Delhi Recreational Facility and Water Quality District Board of Trustees was called to order by President Steve Leonard at 3:15pm at the Heritage Bank Conference Room.

Trustees present: Burger, Colgan, Davidson, Gifford, Leonard, Kramer  

Trustees absent:  Kray

Visitors: Lou & Sue Christensen, Ken & Barbara DeKlotz, Greg Colgan, Chloe Colgan, Ed Schmidt, Pat & Don Dede, Jason Wenger, Larry & Kathy Aschbrenner, Sara Millhouse, Lola Galiher

The agenda was presented by President Leonard.  Burger made motion to approve agenda, Davidson second.  Motion carried.

Leonard welcomed Pat Colgan as a newly elected Trustee and expressed his gratitude to Bruce Schneider, who decided not to run for re-election, for his years of service as a member of the Trustee board.

The first item on the agenda was election of officers.  Leonard asked for a motion to discuss the process of the election of officers.  Burger made a motion that we continue with the current officers for the next 60 days so that we can hold some work sessions with goal settings and then hold a permanent election after that.  Davidson seconded the motion.  A lengthy discussion was held which included how elections have been held in the past and how committees have been set, the vagueness of what is spelled out in Chapter 357E of the Iowa Code, which defines our recreational water quality district, and how we want to proceed going forward in working as a board.  After more discussion, Gifford recommended amending the motion to set the re-election of officers by October 1st, Burger seconded the motion.  Motion carried.

The next agenda item was to consider and approve change order #3 from Lunda Construction in the amount of $2,338.50.  The work is required due to the advantage of using the two tubes to dewater the upstream side of the project for both Phase 1 and Phase 2 work. This may help Phase 2 bids to be significantly less due to a potentially smaller main channel cofferdam required of the Phase 2 contractor. Colgan and Stanley Engineering recommended this change order and three of the trustees signed off on it earlier this week per the resolution we approved previously giving the Board the ability to do so.  Leonard asked for a motion to officially approve change order #3.  Davidson made the motion to approve, Burger second.  Motion carried.

Jason Wenger from The Burrington Group, Inc., provided the board with a summary of the bids for the Rock Nook Association Water Treatment solution.  The board received one bid from Groth Services in the amount of $242,431.05.  Wenger said the board could either accept the bid as received or reject and ask to have the project rebid.  He indicated that there were four other bidders who declined to bid at the last minute because of the November timeline.  Gifford indicated his disappointment in having only one bid.  Following discussion, a motion was made by Colgan, second by Burger to accept the bid from Groth Services.  Burger, Colgan, Leonard and Kramer voted yes. Davidson and Gifford voted no.  Motion carried.

Leonard opened the meeting up for public comment.  There being none, Burger made the motion to adjourn, second by Davidson.  Motion carried.

A work session followed immediately after the special meeting.  Two items were scheduled for discussion.

The first item was discussion of funding for various lake activities. Gifford asked for this item to be put on the agenda.  He spoke of conversations he’s had with various people regarding whether or not the District should invest in lobbyists or not.  He commented that one of the key things lobbyists can do for the District is help gain funding from various state and federal agencies.  Gifford said he thought there was a varying opinion among the Trustees as to whether we should pursue funding and that was why he asked for some discussion. 

Burger expressed his concern about funding sources and if there would be matching funds associated with different grants and, if so, how much would the District have to come up with and where would those monies come from.  He would like more information on the matching amounts and would like to have more discussion at our future work sessions.

Colgan expressed his support to keep the lobbyists until at least next summer and likened them to be somewhat of an “insurance policy” during the reconstruction period.  He also said he needs more information regarding the funding sources and the matching fund but at this point he feels it’s prudent to continue working with our lobbyists. 

Leonard commented that the District has needs and is always going to have needs even after the dam is built.  He feels the District has lots of goals with limited funding ability.  He feels we need to find a balance.  He also mentioned his concern that dredging is becoming an increasing frequent need and the District is going to have to have a plan for this and will need to be prepared.

Gifford felt this discussion was helpful.  Leonard asked that next step be to define what our projects are and assign project managers.   Lola Galiher reminded the Trustees that quite awhile back there were sign-up sheets for various projects and wondered if those lists still existed.  Leonard responded that the District still had those volunteer sign-up sheets and will use them moving forward.

Leonard reminded the group that when the three-member board went to a seven-member board we were in an emergency situation.  Colgan said he did not want to disparage what the past board has done and said it was incredible, when the dam went out, how things were very chaotic but then how so many things got organized and so much was accomplished.  He then said now is a good time to look forward and decide how we want to operate moving forward.  He asked Gifford and Colgan discuss their thoughts.  Colgan again said he thinks we need a work session and need to be pro-active as a board and his hope is that we can work together as a unified board to get our goals accomplished.  Gifford asked if we wanted to have these discussions at our next work session and Colgan said yes.  Leonard ask if, at this meeting, Colgan and Gifford could talk about what their ideas are so that we could set a date for another work session and have an objective for that meeting of what we need to accomplish.  Colgan said he wanted it understood that he is more about what we need to do versus how it gets done.  Gifford said how he is seeing this, from a chart standpoint, is that we need to determine our value / goals and beneath that we need to determine the necessary projects and beneath that we need to choose our project manager/s and team members.  He also asked if this was going to be done at a future meeting.  Colgan thought we should have a meeting in the next several weeks. Burger said he feels we need to identify and then prioritize our projects by money and by year.  There will be things we can’t do right now. There are things we don’t have funding for.  Some projects may be conditional based on funding.

Leonard said he envisioned a work session that could last anywhere from 3-4 hours.  Colgan expressed an interest in having the work session away from our current meeting place to allow the board members to more freely express themselves.  Gifford agreed that a change of venue is a good idea and that we could facilitate our own meeting and sees this as an annual process.

Leonard asked for dates that might work and the general consensus was to hold it on the date of our next regular meeting, which is Thursday, August 21st earlier in the day at a location to be determined.

Barb DeKlotz raised the question of why we need the lobbyists when we have people on the lake who are able to write grants.  Leonard explained that the lobbyists won’t write the grants but they will take a well-written grant and turn it into a great application and have higher probability of success.

Larry Aschbrenner asked if the board as the board reviews project objectives would they be asking for thoughts from folks on the lake. Leonard said as we define the high level projects we will need ideas and help from the community.  Gifford thought a survey might be a great way to ask for information.   Several thoughts were shared on how and when we send out a survey.  The general consensus was that we need to get the survey out fairly quickly before our September 21 meeting.  Gifford suggested that rather than present specifics issues on the survey for feedback from residents, the Board ask for general input.  As an example, “What to do think are the biggest issues facing Lake Delhi and tag them as urgent, not urgent, etc.”  It was generally agreed that the survey ask this question first and after tallying the information another survey could be sent out asking for volunteers who have expertise in the project areas to step forward.

Burger made a motion to adjourn from the work session at 5:45 p.m., Gifford seconded.  Motion carried.

Dam Construction Update July 24, 2014

Delhi Dam Construction Progress Report #5

July 24, 2014

General Project Information

Phase 1 was awarded to Lunda Construction Company in April 2014.

The DNR permit allowing the entire project to be constructed including Phase 2 has been received clearing the way to complete the project.

The important critical goal of Phase 1 work is to complete enough refurbishing work on the concrete structure to allow river water flow to be diverted from the current river bed through the concrete structure.

We are now reasonably confident that Phase 1 work will be substantially complete by October  2014 allowing for the river to be diverted through the refurbished concrete structure. Therefore, the Trustees at a meeting on July 24, 2014, approved going out for bids the week of July 28, 2014. Bid period will be four weeks and with a week or so to evaluate the bids, the work on Phase 2 will mobilize in early September.

Project completion date is dependent on several factors including river flows being average or below, few weather extremes in the next 12 months, selecting a quality contractor for Phase 2 equivalent to our Phase 1 contractor and finally that the flow in the river at the time needed to refill the lake is sufficient.

Right now, again for planning purposes, we are planning for a July 4, 2015, date to resume enjoyment of Lake Delhi. It could be ready sooner if everything listed above goes great.

Specific Progress by Lunda on Phase 1 work through July 8, 2014 includes:

River flows are returning to more normal summer flows and have been at average flows. This high river flow has slowed work on the project due to flooding of the upstream and downstream cofferdam areas.

The upstream cofferdam has been strengthened to reduce leakage to a tolerable amount allowing work to proceed on upstream side of work area.

Saw cutting continues on pier removal. Here workman is making a vertical cut with his 4 foot diameter saw. You can see the gray saw blade protected by a large shield with the workman behind. You can also see the beginning of the horizontal cut mid way down n the lier. The saw rides on tracks attached to the concrete pier.

Work returns to the upstream side following cofferdam fixes. Here the rebar is being installed and the wooden forms are being place to allow the anchor block to be filled with concrete. This is required to meet Corps of Engineers permit stability requirements.

 

Pumping concrete into anchor block form. Top picture is concrete pump on top of spillway. Bottom picture is the large anchor block being poured in one operation. This is one of the largest pours  for Phase 1, over 60 cubic yards of concrete.

Finally, View from downstream side taken July 24, 2014 showing workman on upstream side preparing to remove concrete on the bottom of the spillway opening. Also, you can see water flowing through the two openings midway down the spilway. These are the functioning 37 inch diameter tubes connecting the upstream and downstream areas on teh work area. This is how the contractor is able to manage the upstream cofferdam leakage by allowing it to flow out through these two tubes. These tubes were also used in 1928 when the original structure was first built.

Work Progress through July 24, 2014

Lunda has poured Rock Anchor Block north of Sluice Gates. Concrete sawing for pier removal is approximately 80% complete. Lunda has removed all but the bottom 6.5 ft. of the north and south Pier Noses.

 

The Concrete Condition Survey on the Spillways and Spillway walls continues.

 

Lunda continues to install sheet pile shoring at the northwest corner of the Powerhouse.

 

Lunda’s priorities are as follows:

 

Continue Pier Nose removals, saw cut concrete at abutment walls, and begin demo & rehab on spillway walls following the Concrete Condition Survey for the spillway walls.

 

Setting Tie-backs for shoring at the NW corner of the dam..

 

Continue dewatering. Complete pouring Rock Anchor Block.

 

Begin Rock Anchor Foundation Grouting.

Burger says the building needs a new roof and we should understand the plan for that.  Burger also indicated a 28E agreement would be in order to understand the agreements between us and the school board.

Finance committee – no update

Dam Construction/Timeline – Leonard said the water backup permit has been signed and is on its way to us.  Colgan gave update and advised 3 weeks of rain did impact construction.  Lunda has repaired the coffer dam and as of Monday, all of the extra water was drained down again.  Lunda has been working on the concrete pier removal.  An inspection of the silting basin floor shows it was intact and in good shape.  The ordered gates may be delivered early.  Phase II is ready to go out for bids.  Gifford said Colgan’s pictures and reports are all posted to the District web site.   Leonard said the construction committee members met with Colgan and discussed potential next steps for dredging.  We should do core drillings and there will be recommendations coming to the board soon.  Stanley is working to get an estimated cost of the primary areas of the lake bed.  Colgan said we have the measurements of the tops of the sediment, but not the bottom.  We need to know the depth of the sediment to know the volumes.  The sand is less at Linden acres now than right after the breach but is building up at the Maples.  Colgan said Stanley is putting together a bid proposal for us to hire someone to do the shallow borings.

Lake bed – Gifford did a kayak trip from Baileys Ford to Linden Acres for data collection and to  identify which items have debris or tree issues.  Gifford said he was surprised that there still is a significant tree issue and he is now in the process of working with the road associations to get the trees removed.

Legislative –  3 Trustees met with Gary Grant to talk about next steps. Leonard and Gifford gave presentation of where funds may be available and the benefits of advocacy.  Burger suggested we have a work session at the next regular session to discuss how the lobbyists would work with us to accomplish it.

Property Management – There is a large wash out at the driveway of the office building down by the dam.  Pat Dede suggested talking to the county for  help.

Public comment – Ben Pasker indicated he thought erosion mitigation on the road should be done when the spillway is completed.

Ed Schmidt said he had provided a newspaper article regarding federal money for dredging.  Kramer indicated she had the document and would forward to Leonard. 

Jim Locke would like to see if the Trustees would agree to add LDRA information on our web site.  The LDRA web site is having issues and the cost is too high for what needs to be done.  The LDRA would like to abandon their web site.  Gifford said it could be done with little trouble.  Trustees will put this item on their next agenda. 

Motion to adjourn by Burger, Kramer second, all ayes, motion passed. Meeting adjourned at 7:57 pm.

Delhi Dam Construction Progress Report July 8, 2014

Delhi Dam Construction Progress Report #4

July 8, 2014

General Project Information

As has been discussed, Phase 1 was awarded to Lunda Construction Company, a large and experienced heavy structural midwest firm from Wisconsin in April 2014.

The DNR permit allowing the entire project to be constructed including Phase 2 has been received clearing the way to complete the project.

The important critical goal of Phase 1 work is to complete enough refurbishing work on the concrete structure to allow river water flow to be diverted from the current river bed through the concrete structure.

The timing of the Phase 2 bidding depends on being confident that Phase 1 work will be substantially complete by October  2014 allowing for the river to be diverted through the refurbished concrete structure. Right now in looks like Phase 2 work will be bid in July 2014 for an August 2014 contract mobilization to begin this work.

Project completion date is dependent on several factors including river flows being average or below, few weather extremes in the next 12 months, selecting a quality contractor for Phase 2 equivalent to our Phase 1 contractor and finally that the flow in the river at the time needed to refill the lake is sufficient.

Right now, again for planning purposes, we are planning for a July 4, 2015, date to resume enjoyment of Lake Delhi. It could be ready sooner if everything listed above goes great.

Specific Progress by Lunda on Phase 1 work through July 8, 2014 includes:

River flows are returning to more normal summer flows although they are still higher than average. This high river flow has slowed work on the project due to flooding of the upstream and downstream cofferdam areas. Temperatures have been from the 60’s to the mid 80‘s. Several rain events have also slowed progress.

The upstream cofferdam had to be strengthened following the high water event of the last week or so to reduce leakage to a tolerable amount.

Lunda has had to use Swamp Mats to bridge the mud on the upstream side of the dam so a track hoe could access the SW corner of the dam to set sheet piling in the existing upstream cofferdam to stop water from leaking into the Rock Anchor excavation.

Following driving sheet pile at this location, Lunda is drilling a grout curtain to stop water from entering the excavation hopefully allowing the area to be made ready to resume work on the rock bolting requirements for Phase 1.

Concrete sawing has continued on existing pier noses for their removal. Lunda has removed the top 6.5 ft. of the north pier nose and hauled it to the farm up X31 at the top of the hill.

Work Progress from June 20, 2014, to July 8, 2014

Excavation for the Rock Anchor Block is 90% complete and on hold until the area can be dewatered.

Lunda has finished assembling scaffolding and placing it on top of spillways for pier nose removal.

Eastern Iowa Concrete Sawing has been sawing on existing pier noses for removal.

B&J will continue pumping ground water from stilling basin.

Downstream Silt removal required for inspection is complete.

Finally, Lunda is constantly moving equipment and material to and from the site from their headquarters in Little Shute, WI, as needed due to the tight working conditions on the north side on the dam w here Phase 1 work is happening. Below the large track hoe shown above left the site today as it’s work is done for now. Sightseers are doing a good job of staying away from this work area and it is appreciated by the project.

Next Dam Construction Report – Thursday, July 24, 2014

Pat Colgan

Dam Construction Update for June 23rd – June 27th 2014

Monday, June 23 was a lost work day due to all the upstream and downstream work areas being flooded from the previous Friday flood of over 8000 cfs. Normal flow for this time of year is 350 cfs. The upstream and downstream cofferdams remained in tact but repair work was required. Downstream the settling basin needed to be restored before the pumping could begin to pump out the loser area. By mid week the area was restored for construction.

Also, notice that the two sluice tubes near the bottom the first spillway were pressure water cleaned of all soil debris and the sluice gate on the upstream side of the dam was opened successfully. These tubes will be used on Phase 1 to keep the upstream area dewatered and for Phase 2 to help divert the river flow around the major cofferdam through these openings under the dam. This remains a pleasant surprise for the work required to restore Lake Delhi.
