RE: Proposal for Bird of Prey Occupying Trees On-site Survey and Black-footed Ferret
Survey at the Hokestra Gravel Pit Expansion Site in Weld County, Colorado
Dear Mr. Nelson:
This letter serves as a proposal for a Birds of Prey survey and a black-footed ferret survey to
be conducted at a gravel mine expansion site located near the St. Vrain River in Weld County.
I understand that the scope of work for the birds of prey survey would include:
* ground reconnaissance of the project area;
* determination of any birds of prey nests at the project area, including the species
occupying the nest;
• prepare report of results of the survey; and
* submit report to Weld County.
I understand that die scope of work for the black-footed ferret survey would include:
* ground reconnaissance of the project area;
* determination of density of black-tailed prairie dogs on-site and acreage of
continuous prairie dog colony extent;
* if density and acreage of prairie dog colony is found to be sufficient, night
surveys would be conducted;
* prepare report of results of the survey;, and
* submit report to Weld County.

The estimated cost for the birds of prey survey and the black-footed ferret survey at the
Hokestra gravel pit would be $300.00 and $700.00 total fixed cost, respectively. This cost does
not include the night surveys for the ferret since preliminary field reconnaissance indicates the
acreage and density do not meet requirements for that level of surveying. The cost estimates
include the tasks outlined above and drafting, review, and other direct costs. If you have any
questions, or require additional information, please feel free to call me at 970-635-9183.
Sincerely,

SUBJECT: Professional Services Contract with Dar Tiglas
COLORADO
Attached is a proposal from Darcy Tiglas for a biological survey to be performed at the liokestra Pit.
The survey for birds of prey and the black-footed ferret was required as a condition of approval for
the pit, but it was never accomplished. I am requesting your assistance in obtaining approval of this
proposal.
The Public Works Department has extensive experience with Ms. Tiglas on biological
surveys/studies and found her work to be highly regarded by State and Federal agencies responsible
for review of this type of work.
I have reviewed the scope. It is acceptable and consistent with the requirements set forth in the
Hokestra Pit conditions for approval.
It is our experience that Ms. Tiglas' fees arc typically very nominal, which is again the case for these
surveys. It is my judgement that her proposed fee of$1,000.00 is less than any other firm could
propose.
