Approve Plans and Specifications for Coulter Boulevard; Authorize
Advertising for Bids - Project No. 97-1B-2
The project consultant engineer, Bonestroo & Associates, has prepared the project
plans and specifications for Coulter Boulevard Phase II Extension, Project No. 97-1B-
2 as authorized by the Chanhassen City Council at their regular meeting on February 9,
1998.
The public improvements will consist of the construction of Coulter Boulevard from
its current terminus at the west end of the Autumn Ridge development west to the
intersection with Century Boulevard. Based on input staff received from Council,
there will be trail on one side of the roadway only (the south side) and street lighting
will be shoebox-type with 150 watt luminaires spaced at 300 feet on the south side of
the trail. The boulevard trees will be a mixture of deciduous, coniferous and
ornamental trees with the seeding mix being a dry prairie mix on the upland slope and
wetland mix directly adjacent to the wetlands. Also included in the design is a storm
sewer collection system which will convey road runoff to nutrient removal (NURP)
and sedimentation ponds to be constructed with the project.
The estimated construction costs for this project are in line with the feasibility report
for Project No. 97-1. Specifically, the feasibility report provides a project cost
estimate of $791,000 for the street construction.
The proposed schedule is as follows:
Council approved plans
Plans to bidders
Bid opening
A ward contract
Begin construction
Complete base paving
Final project completion
May 11, 1998
May 26, 1998
June 16, 1998 (9:30 a.m.)
June 22, 1998
July 6, 1998
October 2, 1998
July 1, 1999
A complete set of project plans and specifications are available in the City Engineer's
office should any of the Councilmembers care to obtain more detailed information.
City of Chanhassen. A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, and beautiful parks. A great place to live, work, and play.

As indicated above, the City Council authorized the preparation of plans and
specifications for this improvement project on February 9,1998. The focus of an
agenda item to approve project plans and specifications would normally entail
reviewing the consistency of project plan elements as compared with that originally
authorized by the Council at the feasibility hearing. EstiIl)ated project costs are also
verified to be consistent with the previous estimates. With these criteria being met, the
project plans and specifications are then approved and the project is put out for bids.
This particular project is somewhat unusual in that it has drawn out some late (11 th
hour) controversy as to whether or not the project should proceed. (It is important to
note that public hearings were held last summer and fall.) A number of letters, both
pro and con, regarding this proposed project have been received since the City Council
authorized the preparation of plans and specifications. These letters have been
included in the Administration Section of this City Council packet.
The transportation analysis related to this proposed improvement project has
confirmed the findings of previous local comprehensive transportation studies which
have concluded that this road is a vital element of the City's local transportation
system. The ramifications of not building this road are significant, however, for those
not well versed in the transportation field, the magnitude of resulting problems for this
community may be difficult to comprehend.
Engineering and Planning Department staff recommend the City Council approve the
plans and specifications for the Coulter Boulevard Extension Project No. 97-1B-2
dated May 11, 1998 and authorize advertisement for bids.
