Dear Ms. Wehner,
We have reviewed your letter of January 9, 2020 requesting additional information. We
have revised and/or added the appropriate information that was requested. Please review
the included information to see that it is satisfactory. Should there be any more
additional requests, please reach out directly and we will ensure that it is provided
timely.
Sincerely,

Provide proof that your company has obtained the buffer authorization from
the Division of Water Resources for impacts to the buffer from the access road
and fencing.
Paul Stimpson coordinated with Sue Homewood, DWR on 1/22/20; the
perimeter security fencing will be exempt because trees will not be cut in the
areas of the stream buffer. The perimeter security fencing will be meandered
as needed. A note has been added on sheet C301 E that no trees will be cut
where the perimeter security fencing is within a stream buffer area
Provide details on the installation of the arch culvert installation and the work
across the stream to prevent sedimentation during installation and
construction.
Paul Stimpson coordinated with Tamara Eplin on 1/21/20. The construction
sequence for the Arch span culvert has been updated, on sheet C301 B, to
include the temporary culvert equipment crossing on the west side of the
proposed arch culvert. Also, a detail for the temporary culvert equipment
crossing has been added to sheet C301 B
3. Show the sediment basin baffle placement on the plans indicative of field
conditions. Proper baffle placement in the basins affects the desired volume
between baffles and allows access for maintenance.
Paul Stimpson coordinated with Tamara Eplin on 1/21/20. The skimmer basin
detail has been modified on sheet C502 to adjust the baffle spacing for 25%
increments. The baffle placement for each skimmer basin has been modified
on plan sheet C302. Also, construction specifications and maintenance
information for the porous baffles has been added to sheet C502
4. Please re -contact the 20 well owners that did not respond to your company's
well survey and obtain the well survey data provided for most wells within the
zone of influence. Please detail in your written response your efforts to contact
these well owners.
Groundwater Management Associates has completed the residential water -
supply well survey, the report is attached.
