pursued at the spillway to effect a lowering of the lake.

John,
The site visit to the North Lake project area (Task 1) is required in order to write the preliminary
jurisdictional determination (Task 3), as stated in the scope of services. This said, we will need vehicular
and pedestrian access to the project area, including the perimeter of the reservoir, in order to assess and
document the following:
0 All inflows to the reservoir;
0 The design spillway and the functioning outflow;
0 Any other water bodies (i.e., wetlands, etc.) within the project area; and
• The receiving stream for the outflow.
These data will be needed for the pre - application meeting with the U.S. Corps of Engineers (USAGE) in
order to provide them with a clear understanding of the existing conditions (presence and location of
waters of the U.S.). We will also assess the existing conditions of the project area in order to provide the
USAGE with a habitat evaluation within the project area in regard to the presence /absence of federally
listed threatened /endangered species for Dallas County.
Please contact me if you have any questions or need additional information.

Can you get a one page scope of work explanation from Freese detailing the inspection and work they
need to do under the access agreement we are seeking from Luminant? We need it asap. Thanks!

The saga continues. Just got off phone with our attorney and he stated that the Luminant attorneys
want a list of the exact test to be performed on the site. When you list the test, you might as well list
out how the test is performed, i.e., drill hole xx feet deep to extract soil to test, ..... Not sure what exact
test you are proposing, but try to identify them. Our attorney will try to put some it room in the
agreement to provide some latitude once we are on the property.
Thanks

Well at least it's still moving. This specific site visit will be visual only, no tests.
However, given the trouble, we might as well get permission to do the drilling, though that won't happen
until we're authorized for the final design. The text below is form the proposed scope. The attached figure
shows the location of the inlet and outlet and the other two holes would be along the pipeline.
Perform up to 4 geotechnical borings at the dam, which would include one at the inlet, two along the
pipeline alignment, and one for the outlet structure. Lengths will vary from 35 to 70 feet.
a. Subcontract with a drilling contractor to drill the borings at the proposed locations. The borings will
be drilled with either continuous flight or hollow -stem augers. Obtain soil samples for laboratory testing
using thin - walled sampler tubes in fine - grained soils, perform Standard Penetration Tests in
coarse - grained soils to obtain samples and perform cone penetrometer tests on rock in the field. Backfill
borings with cement- bentonite grout and plug the upper foot of each boring with concrete sack mix to
prevent a tripping hazard.
This would probably be 2 or 3 days on site for a drilling rig.
Whether you want to mention the drilling permission at some future visit is up to you, but this initial
request is just for two folks to walk around and take pictures so they can describe the habitat and the
environmental impact of lowering the lake.
