MEMORANDUM

FROM: Alyson Fauske, Assistant City Engineer rf�lv
DATE: October 24, 2016 DG'
SUBJ: Minnewashta Manor Reconstruction Project 16-01: Approve the Plans
and Specifications and Authorize the Advertisement for Bids
PROPOSED MOTION
"The City Council adopts a resolution approving the plans and specifications and
authorizing ad for bids for City Project 16-01, Minnewashta Manor Street and
Utility Improvement Project."
City Council approval requires a super majority vote of the City Council present.
BACKGROUND
At the June 22, 2015 work session, staff reviewed with Council the proposed 2016
Street Reconstruction project.
On August 24, 2015, the City Council authorized preparation of the feasibility study.
On November 18, 2015, an open house was held to discuss the proposed project.
On December 14, 2015, the City Council accepted the feasibility study and called the
public hearing.
At the January 25, 2016 meeting, the City Council held the public hearing and
authorized the preparation of plans and specifications.
On February 22, 2016 the City Council approved the plans and specifications and
authorized the advertisement for bids.
The bid opening for this project was held on March 24, 2016. Only one bid was
submitted and was over the engineer's estimate and the budget for the project.
On April 24, 2016 the City Council rejected the bid. Property owners were notified
of the project delay.

DISCUSSION
Approximately 1.1 miles of streets are proposed to be reconstructed due to the condition of the
pavement and the utility work that is required within the project area. The Minnewashta Manor
area is located in the northwest corner of the city. The streets were constructed in 1971 and were
sealcoated in 1994 and 1999. The pavement condition indices (PCIs) from the 2014 pavement
condition survey are shown below. A PCI of 100 represents a new street; a PCI of 0 represents a
completely deteriorated street. A PCI below 45 typically indicates distresses that require
reconstruction of the street.

The street widths vary between 20' and 28' within 50' or 60' wide right of way. The drivable
portion of the streets (i.e. the bituminous surface and the concrete gutter) is proposed to be the
same as the existing widths. The proposed pavement section includes 18" of sand, 10" of Class
5 and 3.5" of bituminous as recommended by the soils engineer.
It has been the City's practice to install concrete curb and gutter in reconstruction projects
whenever possible. New developments always include concrete curb and gutter. Concrete curb
and gutter effectively conveys drainage from the bituminous section of the street which helps to

prolong the life of the street. It also provides a delineation between the street and yard which
helps snow and ice control operations minimize yard damage. The addition of curb and gutter
also directs run off to storm water features so the water can be treated and not end up in side or
back yards where it can cause problems. Staff recommends high back, B-618 curb in this area
due to the hydraulics of the style.
Water Main Improvements
The water main in this area
is either cast or ductile iron
pipe. Locations of 10
documented water main
breaks are shown on the
graphic below.
Staff proposes to replace
the water main with PVC
water main. All services
would also be replaced.
Alternatives to open cut
installation, such as pipe
bursting and directional
drilling, will be bid as a
potential time and cost-
saving measure.
Sanitary Sewer Improvements
Staff has investigated and
televised the condition of the
sanitary sewer in this area.
Approximately 50 feet of
sewer is proposed to be
replaced due to the condition
of the pipe.
The remaining sewer pipe is in
good structural condition,
although some require mineral
removal, grouting and/or lining
to reduce the incidence of
inflow and infiltration. These
minor repair areas are also
proposed to be fixed at this
time.

A 10" diameter sanitary sewer force main extends from Lift Station #4 and under the north -south
section of Washta Bay Road. The Utility Department potholed the ductile iron force main and
confirmed that the pipe is in good condition. An anode bag will be added to act as a sacrificial
material to prolong the life of the force main.
Storm Sewer Improvements
The existing corrugated metal pipe within the Washta Bay Road and Sandpiper Trail right of
way is in poor condition and is proposed to be abandoned and filled with sand. Reinforced
concrete pipe is proposed to be installed within these streets. The corrugated steel pipe that
serves TH 7 and is along Washta Bay Road is in poor condition and should be replaced.
The project area is fully developed, therefore, there is minimal space to provide traditional
stormwater management, namely treatment ponds. The project includes a rain garden at the
corner of Washta Bay Road, SAFL baffles and improvements within the vacant right of way
from the Tanagers Lane/Sandpiper Trail intersection to Lake Minnewashta. Restoration of the
wetland south of Sandpiper Trail is proposed to be completed in-house next year for budget
purposes.

The plans and specifications have been updated to reflect the City's current specifications and
detail plates; the changes are minor. Copies of the plans and specifications are available in the
engineering department.
PROJECT FUNDING
Assessments will be based on the City's assessment practice of assessing 40% of the street
improvement cost to the benefitting properties on a per lot basis. The assessments would be
proposed for a 10 -year term at a preliminary interest rate of 5.25%.

Budgets for the proposed work have been included in the 2016 CIP. The City's engineering
consultant has updated the estimated cost of the project based on the current bidding climate.
The proposed project schedule has the bid opening three months earlier than usual in effort to
attract numerous bidders and competitive pricing. A summary of the engineer's estimate and
CIP budget is below:

City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends tht
of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective.
abilitation projects extend the life of the street. In cases when utilities or poor sub grade needs to be replaced or where streets have
xiorated to a point where rehabilitation will no longer be practical, reconstruction of the street is necessary. A feasibility study is written to
sider the merits of the project and scope of work.
Highway 212 improvement project included a pedestrian trail along the first 2,500 feet of Bluff Creek Drive. The resulting "gap" represents a
ging link in the City's trail system south to Flying Cloud Drive. Bluff Creek Drive is a difficult stretch of road to negotiate as a pedestrian in
Lbsence of a trail. This trail segment is nlanned to he nnnam,nted ainnn v ith ti,a,)ni v nese

replacement may be the most cost effective option. Given the highly corrosive soils in the City, water main replacement is an ongoing
