Dry Creek Trail Bridge Across the South Platte River

Dear Bill:

With respect to the requirements for the proposed easement within the Colorado Water Conservation
Board (CWCB) owned right-of-way along the South Platte River, this letter is intended to describe our
understanding of, and compliance with, the relevant environmental and floodplain regulations for this
area.

We have prepared construction plans and specifications for the proposed bridge that will span the South
Platte River at the confluence with Big Dry Creek, connecting the Big Dry Creek Greenway trail with the
Mary Carter Greenway trail along the west bank of the river, The project will be bid between March 6 and
March 27, 2002, and award of the construction contract is planned for the April 10, 2002 meeting of the
South Suburban Board, The following describes the procedures completed and/or underway with respect
to floodplain and environmental regulations,

Research was completed to document the 100-year floodplain for the South Platte River and Big Dry
Creek at the proposed bridge site. A report was prepared (February 13, 2002) to present this information
and to show that the proposed bridge does not adversely impact 100-year flood elevations, This report has
been submitted to the Colorado Water Conservation Board, the Urban Drainage and Flood Control.
District, the City of Englewood, and the South Suburban Park and Recreation District. The proposed
bridge design will conform to all state, local and federal floodplain regulations,

Environmental Regulations

Nationwide 33 permit on March 18, 2002, A copy of the permit will be made available to prospective
