space; bridge construction and rehabilitation that increases safety; enhanced wetlands;
reassignment of Town staff time due to reduced floodplain management and floodplain mitigation.

The Town Council and staffhas conducted a number of meetings with potentially interested
parties including:

1) Larimer County Staff
2) City of Fort Collins Staff
3) Town and County Residents
4) State and Federal Agency Staff

Specifically, the Undetained Diversion to Boxe1der Creek alternative addresses the following
points of the town's comprehensive plan (please reference the comprehensive plan for the
bracketed, numbered items).

1) Support economic development (Principle 10)
2) Accommodate pedestrians and bicyclist (Principle 12)
3) An abundance of open space (Principle 17)
4) Create a strong favorable impression and community identity (Principle 19)
5) Encourage the expansion of community services and amenities) (Principle 21)
6) Improve or expand park facilities (principle 24)

Alternative Five also has the support and cooperation of impacted land owners, County and Town
residents. Several landowners that will be impacted by the construction of facilities and asked for
right-or-way have been cooperative and will provide right of way or easements. County and
Town residents have voiced their opinions of the proposed project at several public forums. The
residents are in support of the project because of its multi-use functionality, potential for open-
space and because of the reduced flood hazard to a large part of town.

One other important part of an overall Flood Mitigation Program is a Flood Detection Network
(FDN). The typical installations include Automated Stream Gaging stations based on channel
volume, radio signal range and major population areas. The City of Fort Collins has a FDN and is
studying the installation of additional monitoring stations along the Boxelder Creek. The preferred
alternative includes the construction of 4 monitoring stations within the Coal Creek and Boxelder
Basins. These monitoring stations would relay information to Wellington Town Hall and be
compatible with the Fort Collins system. This system is considered a pro-active step to a complete
Flood Mitigation Program and highly recommended for inclusion in the selected Alternative.

ENGINEERS ESTIMATE OF PROBABLE PROJECT COSTS

Provided in Appendix A are the spreadsheets for each of the structural alternatives showing the
specifically attributable project costs. The identified project costs include soft project costs in
addition to hard project costs. For purposes of this report, soft project costs include legal fees,
engineering fees and financing costs. Hard project costs include the construction of project
features and land acquisition. Stated another way, the Engineers Estimate of Probable Project
Costs provide a feasibility level view of the total costs attributable to make a complete
