Following is a recap and status of the ongoing Lake
Spivey silt removal project.
February 1 - 11
Work officially began on Tuesday February 1, 2010 as McEachern Dredging staged
their equipment and dug a release trench to drain the water beside the
peninsula. On Wednesday February 2, 2011 they started removal of sediment from
the Forest Estates canal -- placing the removed silt on the peninsula.
McEachern continued to work in the canal and completed the removal of 390 cubic
yards of soil on Friday February 11, 2011. All work was done with one long
reach front-end loader.
RCI engineers inspected the work and signed off on the
completion.
February 12 -18
McEachern Dredging staged their equipment -- one long reach front-end loader
and two dump trucks -- at RMS-6 to begin the removal of 791 cubic yards of
silt. Muddy conditions rendered the peninsula temporarily inaccessible to
trucks so in order to keep the project moving forward, dirt was instead hauled
to Walker Nursery. Mr. Walker was
able to establish a gravel trap to assure that dump truck tires were
sufficiently cleaned before re-entering Walt Stephens Rd. This portion of the
project was wrapped up on February 18, 2011.
RCI Engineering will take measurements next week and certify
that the work was completed as outlined in the contract.
In addition, LSCA has contacted the Corp of Engineers to request permission for
two additional dredging areas -- the area in front of The Landings Subdivision
(1,492 cubic yards) and the Lost Valley canal (333 cubic yards). We should have
an answer and direction early next week on the feasibility of adding these
areas.
February 19 - 26
Completed silt removal of two small areas -- RMS-2 and South Bay -- totaling
just over 100 cubic yards. At this point McEachern staged the rest of their
equipment - three long reach front-end loaders -- at the Bay View Marina and
began work on the Bay View Marina and canal. Weather permitting; the Bay View
project should be completed by March 11, 2011.
Next steps:
McEachern will be moving to Rum and Vaughan Creek sites.
February 27 - March 5
The Bay View canal and Marina were completed ahead of the March
11 anticipated date and on Friday March 4, 2011; the dredging equipment was
moved to the Vaughn Creek sites to begin removing 9,000+ cubic yards of
sediment. McEachern Dredging is utilizing three long reach front-end loaders
and two tracked dump trucks. Due
to rain and wet conditions, no work could be performed on Saturday, March 5.
March 6 - March 12
Unfortunately four out of the six working days were
rainouts. McEachern Dredging utilized one of the rain days to reposition their
equipment from Bay View to Rum and Vaughn Creeks. They also added one long
reach excavator and purchased a sweeper truck to keep the roadways clean.
They were able to work Tuesday and began building access
roads in the lakebed by utilizing support mats. The heavy rains on Wednesday, Thursday and Friday washed out
most of the work performed on Tuesday. They spent the majority of Saturday repairing the roadways
and they were able to restart the Rum Creek project.
March 13 - March 26
McEachern Dredge now has their full compliment of equipment
available for the project. This includes (5) long reach excavators, (3) tracked
dump trucks and (2) round wheeled dump trucks. With their equipment now
available and on site they are able to work both the Rum and Vaughn Creek
project areas.
The Rum Creek sediment areas were almost completed with the
exception of the 100' sediment basin within Rum Creek. Their goal is to have
Rum Creek finalized by Monday�removing a total of 5,179 cubic yards. They have
completed approximately 30% of Vaughn Creek silt removal.
Next week their plans are to move equipment being used at
Rum Creek to the North Shore Project and continue to work on the completion of
Vaughn Creek.
As of today they have had a total of (16) non-workable days.
Even with inability to perform work on the rain days. McEachern is still
confident that they can have the sediment removal project completed by the April 15, 2011 dead line.
March 27 - April 2
Monday the equipment was moved and stage at North Shore Canal to begin dredging. Tuesday, Wednesday and Thursday no work was preformed due to rain. On Thursday March 31, 2011 LSCA received the approval letter from the COE to add the two additional dredging sites, Lost Valley Marina and The Landings. April 1, 2011 the peninsula job site was issued a STOP WORK ORDER by the EPD. The reason was a Lake Spivey resident issued a formal compliant.
April 3 - April 16
No silt could be be deposited on the Camp Rd peninsula nor could work be preformed on the seawall. McEachern dredging continued working on the North Shore Canal, The Landings and Lost Valley. The sediment spoils were hauled to homeowners and Walkers Nursery. On Friday March 15, 2011 the STOP WORK ORDER was removed and LSCA was allowed to work on the peninsula.
April 17 - April 23
The Landings, Lost Valley and North Shore dredging projects were completed on Tuesday April 19, 2011. Wednesday McEachern continued to work on the Vaughn Creek project while re-staging equipment used for the other projects to Vaughn Creek and the Camp Road Peninsula. Due to the stop work order and the new 25' buffer zone, the original Camp Rd Peninsula could no longer be utilized. McEachern Dredging spend two days constructing a new access road. The cost for this additional work was $4,525.00 bring the total cost of the buffer zone compliance to over $20,000.00.
On Saturday April 23, 2011 the spillway valve was closed to allow the lake to begin to refill!
April 24 - April 30
McEachern Dredging continued work on the Vaughn Creek project. Only one day of work was missed due to day.
May 1 - May 15
Vaughn Creek sediment removal and RMS-8 access road completed. All dredging has been completed.
June 17
All work has been completed including final grading... seeding will begin next week
Seawall Update
There was not a lot of visible activity to report for the
first few weeks� however Vertical Earth did present LSCA detailed construction
plans and wall drawings that were reviewed and approved by both RCI Engineering
and LSCA. Once approved, initial
prep work began. Vertical Earth's
Geo Engineers reviewed the soil report provided by RCI Engineering in order to
address the pre-construction work and wall footings needed to support the wall.
Vertical Earth has continued to make steady progress on the
wall and is on schedule to be out of the lake bed by the agreed upon date of
April 15, 2011. The Stop Work Order has delayed the completion until May 9, 2011
April 1 - April 23
No work could be performed due to lack of access due the EPD stop work order and the lack of an access road.
April 24 - April 30
Vertical Earth had a survey stake out the position of the new Camp Road Peninsula heavy equipment access ramp. They then dug out the ramp area and placed the footings. On Wednesday and Thursday they constructed the forms. Friday the concrete was poured and Steve Schroeder inspected the final product. It met all our requirements.
May 1 - May 21
Seawall and Sidewalks were completed
June 17
All work has been completed including inspection by LSCA hired engineers.
Other News
Two tree removal projects have been initiated as well. Trees situated in a low-lying area
dividing the landmass of the Camp Road Peninsula were cleared and removed. The low area is being filled with sediment
to level the peninsula. This tree
removal will also enhance the view of adjacent property owners.
The second tree removal area is located inside the mitigated
lake area that was approved by the COE. It was necessary to remove a stand of small trees impeding the placement of the new seawall that crosses what
was once lake bed.
All tree work will be completed by March 11, 2011.
I encourage you to
drive to the Forest Estates Marina and look for yourself� it provides a great
view of the progress of the Seawall project
