Re: Roxborough Park Metropolitan District
Wastewater Regionalization Project

Dear Mr. Lang:

Please find attached a Colorado Water Conservation Board (CWCB) Easement Request Application for
CWCB Right-of-Way along the South Platte River, Chatfield Downstream Channel Improvement Project.
This request is to accommodate construction of a proposed pipeline for transmission of wastewater from
Roxborough Park Metropolitan District (RPMD) to the Littleton Englewood Wastewater Treatment Plant
(WWTP). As part ofthe proposed project, RPMD will provide wastewater service to Lockheed Martin Space
Systems (LMSS), which will permit closure of both the RPMD and LMSS wastewater treatment facilities.
Currently, both treatment plants discharge into the South Platte River upstream of Chatfield Reservoir. The
proposed WWTP regionalization project will result in a reduction in the discharge of phosphorus and other
nutrients to Chatfield Reservoir which will provide water quality benefits to the reservoir and South Platte .
River downstream of the reservoir. Attached is a vicinity map showing the overall scope of the project from
the City of Littleton connection point to the RPMD wastewater treatment plant.

The proposed pipeline will connect to an existing City of Littleton wastewater pipeline at the intersection of
Belleview Avenue and Frontage Road F, west of Santa Fe Drive, run west to and across the South Platte River,
then generally parallel the west side of the South Platte River past the southerly limits of CWCB permanent
right-of-way. Accompanying this easement request application are preliminary plan and profile construction
drawings which show the location and extent of the .20-foot wide easement within the CWCB permanent right-
of-way. Legal descriptions and exhibits of the pipeline easement(s) will be prepared as construction of the
pipeline is completed. The tota11ength of the 20-foot wide easement within CWCB permanent right-of-way is
9,618 feet, which equates to a total area of 192,360 square feet or 4.416 a~res. Construction of the pipeline is
tentatively scheduled. for completion by December,2006.

,
There were a number of concerns and issues outlined in your memorandum to the Board dated November 4,
2004. Most if not all offuese issues have since been addressed and/or resolved as the coordination, design and
approval processes for the project have progressed. These issues/concerns are noted in italics followed by
RPMD's response and work progress:

I. Tying up a large portion of CWCB right-ofway for one project. The preliminary construction
drawings show the 20-foot wide easement impacting only 4.416 acres over a'tota1 pipeline length
within CWCB right-of-way of 13,400 feet or 2.54 miles. In addition the pipeline alignment is
typically along the edge of the CWCB right-of-way and in areas where there is existing maintenance
access.
2. Reclamation and mitigation measures during construction. The project plans and specifications will .
describe all reclamation and property protection requirements of impacted property owners
