Introduction
At the November 6-7, 1995 Board Meeting, approval was given by the Board to grant requests for
easements in CWCB's right-of-way along the Chatfield Downstream Channel Improvement Project
(Project) on a case-by-case basis. In addition, at the November 21, 2001 Board Meeting, the Board
adopted the "Easement Guidelines for the Chatfield Downstream Channel Improvement Project" dated
November 2001. In addition, the Board at its May 2005 approved changes to the Easement Fee
Structure.

. There are three methods available to the Board for establishing easement fees for applicants. Method 1
is the Market Value Method and is based on surveys and appraisals, Method IT is the Impact Method
and considers what percent impact will be realized to the CWCB lands for the proposed area and use,
and Method III is the Special Use Consideration that provides the Board with flexibility and discretion
to set a fee based on extenuating circumstances.

Backe:round
On May 16, 2006 the Town of Columbine Valley hired Icon Engineering Inc. for the design and
construction of an outfall pipeline for stormwater discharges into the South Platte River. This projeclt is
approximately one mile upstream of Bowles Avenue on the east bank of the South Platte River. This
outfall pipe will upgrade the drainage conditions provided by a 24-inch diameter corrugated metal pipe
that was constructed in 1956. The new outfall pipe is approximately tOO-feet upstream of the existing
outfall pipe that will remain in use. The new 36-inch reinforced concrete pipe allows for installation of a
sediment trap and oil-water separator for drainage from the adjacent golf course maintenance area. On
August 22, 2006 representatives from Icon Engineering met with staff from the CWCB, the UDFCD,
Roxborough Park Metropolitan District, Columbine Valley Golf Club and the Attorney General's
Office. The purpose of the meeting and site visit was to ensure that the proposed easement request was
properly aligned to cross over the Roxborough Park Metropolitan District waste water pipeline that was
previously approved by the CWCB and is scheduled for construction in early 2007.

.

The applicant was advised to follow UDFCD design specifications for maintenance eligibility.
Representatives from Icon Engineering stated that this project is to be maintained by the Town of
Columbine Valley. On September 8, 2006 staff received an official easement request from Icon
Engineering, Inc. on behalf of the Town of Columbine Valley. Attached to this memo for Board
