SUBJECT: 2008 Street Reconstruction, Project No. 08-02: Accept Feasibility
Report and Call the Public Hearing
REQUESTED ACTION (Simple majority vote required)
City Council is recommended to accept the feasibility study for the 2008 Street
Improvement Project and call the public hearing for January 28, 2008.
BACKGROUND
On September 24, 2007, City Council awarded the consultant contract to Kimley-
Horn and Associates and authorized the preparationofthe.feasibility study.
A neighborhood meeting was held on November 14, 2007. Eighty-six (86) notices
were sent out for the meeting. Approximately 40 residents attended the meeting.
DISCUSSION
The City's pavement management program recommends that streets in the Laredo
Drive area be reconstructed in 2008. The City receives the most complaints about the
condition of Laredo Drive from residents and the traveling public then other
street in the system. The public utilities in the area are old, have had problems
and should be replaced or repaired. Approximately 1.35 miles of stre _ are proposed
to be reconstructed. The area for improvements include: Laredo Drive, Laredo Lane,
Longview Circle, Cimarron Circle and Highland Drive (west of Laredo Drive).
Street Improvements
All the streets are proposed to be reconstructed approximately the same width as the
existing streets. Laredo Drive between West 78th Street and Saratoga Drive is
proposed to be built to a 36-foot wide urban street section.Streets.frPlllS~ratO,ga
Dri ve to Frontier Trail are proposed to be 31' wide. The streets are proposedtobe
urbanized and reconstructed with concrete curb and gutter. Most streets currently
have bituminous curb and gutter. Replacement of the existing sidewalk panels is
included in the project. No additional sidewalk or trail improvements are included in
the project at this time. No included in the project.
The City of Chanhassen · A growing community with clean lakes, quality schools, a channing downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

Public Utilities
The reconstruction project will include the improvement or replacement of most
public utilities within the reconstruction project area. The project includes
replacement and adding additional storm sewer to the streets. Environmental
manholes are proposed with the project to help treat the runoff prior to discharging
into adjacent water bodies. Because the street reconstruction area is built out, typical
stormwater ponding in the area is limited.
Staff has looked into constructing raingardens in the area to treat the street
stormwater runoff. A raingarden is a relatively small area of plantings near the drain
spout of a building or paved area. Rainwater (or snow melt) is routed to the garden
and filtered naturally by the plants and soils in the garden. This filtration process
removes nutrients and pollutants. By acting as a micro-detention pond, the
raingarden plants and soils provide an easy, natural way of reducing the amount of
water that flows from rooftops, lawns, and driveways. Then, using the concept of
bioretention, these gardens remove pollutants from storm water and help restore
natural infiltration. Because of the tight soils, street grades, little right-of-way and
future maintenance concerns, staff has not included raingardens in the project at this
time.
Draintile is included in various areas along the street to pick up residential sump
pump water discharge and reduce the amount of groundwater in the street subgrade.
Reducing the amount of groundwater in subsoils typically increases the pavement
strength.
The watermain in this area is old cast iron pipe which has experienced numerous
breaks. It is proposed to replace all the watermain with PVC watermain pipe. Water
service pipes and curb stop boxes are proposed to be replaced.
The sanitary sewer service has been televised and approximately 1000' of sanitary
sewer pipe is proposed to be replaced. Most of the pipe proposed to be replaced is
old clay pipe that has off set joints, cracks or infiltration problems. By replacing this
pipe it is anticipated that the city will see reduction of inflowlinfiltration (1&1). This
reduction will be quantified and included in the City's MCES 1&1 surcharge reduction
plan for credits. Along with the sanitary sewer pipe, sanitary sewer services will be
replaced.
Estimated Assessments
Per the City assessment practice, forty percent (40%) of the street costs are proposed
to be assessed to the benefiting property owners; the City will be responsible for the
remaining 60%. One hundred percent (100%) of the utility costs will be paid for by
the respective enterprise funds. The residential assessment is the same for all
benefiting residential properties. The estimated assessment at this time is $7,075.00
and was calculated based on the residential areas. The assessments will be
recalculated with actual bids and prior to the assessment hearing. The street

oversizing for 31' to 36' was not included in the residential assessment calculation
the City and commercial properties pick up the oversizing costs. The preliminary
assessment is only for the residential equivalent street section.
The costs for the improvements are proposed to be assessed to the benefiting
properties on a per unit basis. Costs incurred by individual lots are 40% of the total
project cost for street improvements divided among 80 single-family residential
property owners, and 6 commercial property owners.
The total assessment to benefiting properties is proposed as follows:

$1,763,400 x 40% =

$1,763,400

$705,400
$705,400
There are 80 residential and 6 commercial properties proposed to be assessed for the
street improvements. The total assessable front footages for residential and
commercial properties were measured as a basis for determining the assessments on a
unit basis. To determine each commercial equivalent front footage, first an average
property area to average front footage ratio was determined for the residential
properties:
Average Lot Area
Average Front Footage
Ratio
12,560 SF

The property area to total front footage ratio was then determined for each
commercial property:

= 87.44
= 140.84
= 108.05
= 69.33
= 94.77
= 172.50
The ratio calculated for the average residential property was divided by the ratio to
each commercial property to determine a Residential Factor:

This Residential Factor was then applied to the actual affected front footage for each
commercial property to determine an Equivalent Front Footage for each commercial
property:
