MEMORANDUM
TO: Park and Recreation Commission
FROM: Todd Hoffman, Director of Parks and Recreation ,~f//
DATE: March 17, 1999
SUB J: Bluff Creek Trail
The Bluff Creek Trail was postponed in 1998 due to easement problems and an
effort to reroute the trail. The attached plan set reflects the revised (and
improved) alignment. Upon completing city review of these plans, Hoxvard R.
Green Company will seek to obtain a quote to complete the work as a change
order to the 1998 Trail PrQject. Midwest Asphalt holds a contract with the city to
complete this project; however, their pricing was only good through the close of
1998. In the event that Midwest's quote is unacceptable, we will open the project
up to additional bidders.

REVISED PLAN SET - BLUFF CREEK TRAIL ALIGNMENT
Attached to this memo please find a copy of the revised trail alignment for the Bluff
Creek trail segment in Chanhassen. The revised alignment includes minimum trail
surface elevations of 882.0 feet south of the 60" culvert crossing and 884.0 feet north of
the 60" culvert crossing. The project includes installation of two 15" culverts at station
8+80 and 12+50 to allow drainage through the trail embankment to the creek. No culvert
extension modifications are proposed to the existing 60" culvert along Bluff Creek. As
shown on cross-section 18+50 of the plans, the trail fits across the existing width of the
culvert.
Please note that for flooding to occur to an elevation of 884.0 feet north of the culvert it
will be necessary to berm across this culvert to a higher elevation in the future.
Currently, with the trail constructed directly over the 60" culvert, the new trail surface
would not prevent water from flowing over the top of the 60" culvert prior to reaching
elevation 884.0 feet if conditions allowed for this much water in the ditch. We assume
that at some future date the culvert would be extended on each side with a berm
constructed across the culvert extending to the west and connecting into higher ground
to provide for a higher ponding elevation of 884.0 feet north of the culvert.
The future parking area near Audubon Road has been removed from the plans and will
be constructed as a future improvement. The trail is shown connecting directly to
Audubon Road at a location near where the future parking area will be constructed.
We have also included a revised cost estimate of the project showing costs estimated
from the 1998 Chanhassen Trail Improvements project bid by Midwest Asphalt.
We are currently drafting a new easement for lot 5, block 1 and should have this ready to
forward to the attorney later this week. Easements on the two lots near the north end of
the trail remain unchanged.
