SUBJECT:
Dogwood Road/Tanadoona Street and Utilities, Project No. 06-06:
Approve Plans and Specifications; Authorize Ad for Bids
REQUESTED ACTION (Simple majority vote required)
City Council is recommended to approve plans and specifications and authorize
ad for bid.
BACKGROUND
On November 13,2006, Council officially authorized Kimley-Hornto prepare the
feasibility report. This was the same feasibility report paid for by a property
owner in February, 2006.
On January 22, 2007, Council approved the preliminary plat of The Arbors, the
proposed development south of Dogwood Road and west of West 78th Street,
contingent upon the approval and construction of City Project 06-06.
On March 12,2007, Council held the public hearing and authorized the
preparation of plans and specifications.
DISCUSSION
Roadway
At the public hearing, Council directed staff to design Tanadoona Drive and
Dogwood Road north of the Arbors Development to a width of 26 feet. Also,
Council directed staff to design Dogwood Road in the Arbors Development to the
City's standard 31-foot width. The roadway sections were decided to be
urbanized with curb and gutter.
Sanitary Sewer and Watermain
All homes are currently served by individual wells. Three of the northern
properties are served by a small, City-owned and maintained lift station and
forcemain; the remaining properties are served by individual septic systems.
The City of Chanhassen . A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

The proposed utility improvements will provide service to the proposed
development at the southern end of Dogwood Road, The Arbors. Gravity sanitary
sewer will be installed within Dogwood Road and will connect to the lift station at
the southeast corner of Dogwood Road and Tanadoona Drive. The lift station is
proposed to be replaced to handle the ultimate flows for this area. The forcemain
from the lift station to the gravity sewer within Tanadoona Drive is also proposed
to be replaced to convey the additional flow.
Drainage and Runoff
The runoff from the Arbors Development will be conveyed to a storm water pond
constructed with the development. This pond will be constructed and paid for by
the developer. The runoff outside of the development will be directed to the
corner of Dogwood Road and Tanadoona Drive. Staff has contacted Camp
Tanadoona to pursue a drainage and utility easement over the low area of land on
the southwest corner of the Camp property for ponding. If an easement cannot be
acquired, an environmental manhole would be installed to remove some of the
sediment from the roadway prior to draining into Lake Minnewashta. An
appraisal has been completed for the proposed easement area.
ASSESSMENTS/METHOD OF FINANCING
Special assessments are proposed to be levied against benefiting properties for the
improvements included in this project. The City will assess benefiting property
owners based on the construction bid amount of the improvements. The costs for
the improvements are proposed to be assessed to the benefiting properties on a per
unit basis. The development will be assessed 100% of the benefit from the
project. 100% of the water and sanitary sewer improvements will be assessed
back to the benefiting property owners. 40% of the roadway improvements will
be assessed back to the existing benefiting property owners consisting with the
City's assessment practice. The estimated assessment for existing properties is
$30,106.81 per unit and $17,455.45 per unit for properties that have existing City
sanitary sewer service. Assessments are proposed for 10 years at 6% interest.
Funding for this project is proposed as follows:
Special assessments
Revolving Assessment Fund
Storm Sewer Utility Fund
Total:
$ 1,541,362
$ 431,163
$ 365,075
$2,337,600
