Mike and others,
DWR accepts the documentation that has been provided today, and previously via emails regarding the dewatering
technique to be used at the large stream crossings within this project As discussed during the pre - construction
meeting, please notify me of the date you expect to perform the work at the first location Upon completion of the
installation at the first crossing we will evaluate whether this method remains an appropriate alternative dewatering
method for the other large crossings
Thanks,
Sue Homewood

Sue,
Per our previous conversations, please see emails below and attached for revised creek crossing plan
prepared by Layne Heavy Civil for their work on the Muddy Creek Influent Transfer Force Main
project As discussed, Layne has prepared a revised plan which B &V has reviewed and has noted no
exceptions to it I have spoken with Layne and confirmed that the emails below and attached represent
Layne's plan in its entirety
By copy of this email, I am asking CCUC to reply and formally request a modification to the 401 WQ
Permit for the project to allow the revised creek crossings You had previously indicated that you could
issue a revised permit via email
I am also asking Layne Heavy Civil to keep everyone updated on their project schedule and when they
expect to install the first creek crossing
Feel free to contact me if you have any questions or comments
Thanks,
Matt

Matt,
B &V has reviewed the revised creek crossing plan and has the following comments
1 Confirm that Layne will have at least one extra silt bag on site during creek crossing Yes
2 Confirm that Layne will confine construction operations to a 40 -foot width as indicated in Detail
E on Drawing D -03 (bypass pumps and discharge hose can be outside this 40 -foot width) Yes
3 Confirm size of pump Drawing markup indicates a 10 -inch quiet flow pump and narrative below
says 6" or 8" My supplier salesman with Sunbelt Pumps is on vacation this week. I am
meeting with him next Monday 7 -27 -15 to confirm what sizes we will actually need and all
materials and parts as well to have the bypass pumps set up like we discussed. [Skidmore,
Matt] (See attached pump sizing email)
4 Provide stream flow calculations to justify bypass pump size selected. Can provide once the site
meeting with Sunbelt Pumps on next Monday 7- 27- 15[Skidmore, Matt] (See attached stream
flow calculation email)
5 Provide narrative information on plans for dewatering the coffer dam and trenches during
construction Same as #'s 3 and 4. But my plan is to have the bypass pumps set up pumping
from coffer dam and pumping back into creek down stream of work like discussed. I will have
Additional Silt Bags on site as well if we need we will use. The dewatering of trenches will be
done by pumping into silt bag and letting the water discharge towards the creek or however it
is needed to be set up as we progress throughout the project, in making sure no silt in getting
in creeks.
6 Provide narrative information on how concrete encasement of force main will be placed and
allowed adequate time to cure prior to backfilling
When Layne is completing the Creek Crossing, as the pipe is installed all the way across creek.
Layne will order Concrete from our Supplier and have the Concrete Plant add Calcium Fluoride
Chloride to the Concrete mix, this will make the concrete set up and cure very fast as well
pour the concrete encasement over the new pipe. Layne has equipment on site to be able to
perform this work from either side of the creek with using a concrete bucket that will be
attached to the Excavator boom out over the new installed pipe to pour the concrete

encasement. At that time Layne will have 1 Excavator on both sides of the creek installing the
Backfill / Rip Rap per the plan details and cleaning up areas and restoring all dirt areas and
erosion in place.
7 Confirm that this creek crossing revision will not require revisions to the Contract Times and /or
Contract Price Correct, No additional time or additional charges.
Please respond to these comments and provide additional information as requested
Thanks,
Matt

Subject: Muddy Creek Project - Creek Crossing Plan
Sue,
The attached file is a marked up plan, stating our plan on completing the creek crossing for the Muddy
Creek Project
Summary, for work to be complete
Layne is installing 1 complete coffer dam across the entire creek crossing at one time per the
construction details and like we discussed I am going to have a 6" or 8" Bypass Pump System set up
with the proper suction and discharge hoses to handle the water flow of the creeks at the time we plan
to start this work I will also have a secondary bypass pump setup in same location that we can use if the
15` pump malfunctions or problems occur during the bypass pumping of the creek while work is being
completed to cross the creek with the new force main I will also have extra pumps on site for the worse
case of an emergency " mayor rain event" taking place if they are needed I will have all the materials
such as Rip -Rap, Sand Bags, Silt Bags, Pumps, all hoses, force main pipe and fittings to be installed,
concrete for encasement on new force main under creek and Rip -Rap for the restoration of the creek
bed/ banks per the construction details/ specs and like we discussed in our meeting yesterday I will
have enough staff on site to complete 1 creek crossing in 1 day, we will start the crossing at 7 am and
will work all day until we have completed the scheduled work per the construction plans and will
complete in 1 day no matter what it takes Also I will be taking pictures next week of the existing
conditions throughout the site and will also be taking pictures daily before and after all work Before any
of the above work starts Layne will have all erosion control measures in place before work starts and will
also maintain during the creek crossings to protect the creek at all times and throughout the site as work
takes place I will let you know a day or so before we plan to actually start this process in completing
work in crossing all the creeks as work progresses to the crossings Let me know if you have any
questions
Thanks) Matt
