Accent Feasibilitv Report/1988 Sidewalk Reolacement. Citv Proiect #186
On April 5, 1988 the Council authorized Staff to prepare a feasibility report
regarding repair and replacement of existing sidewalks. Staff has completed this
report and a copy of this report is attached for Councils information.
The major issue regarding this project concerns funding. The City has the
authority to notify residents whose sidewalks are in need of repair that the
resident is responsible for repairing that sidewalk. If the resident does not
repair the sidewalk, then the City has the authority to repair it and bill the
resident. However, I believe there is precedent in having the City share in the
cost of repair and replacement of these sidewalks. Tb the best of my knowledge
this was a 50-50 split. I would recommend maintaining this policy for sidewalk
that we have to remove and replace. However, in areas where the sidewalk is in
good condition and is out of alignment at the contraction joints, then I would
recommend that the cost to repair (by mudjacking) be 100% of the City's cost. I
feel that the repair of misaligned joints is more in the area of repair and
maintenance and should be a function of the City.
If the Council agrees that the cost for repair and replacement should be split
with the property owners then the recommended action would be to receive the
feasibility report and order a public hearing for June 21, 1988 at 8:00 p.m.
If Council would decide not to assess any of the cost then the appropriate action
would be to receive the feasibility report and not make any motion for any public
hearing. Staff would then have to work with existing and future budgetary
restraints.
If Council desires I will be available to give a brief presentation on this
project. If Council has any questions or concerns regarding this matter prior to
the meeting, please feel free to contact me at Councils convenience.

EXECUTIVE SUMMARY
`City Project # 186 provides for the replacement of severely cracked and
deteriorated concrete sidewalk in the City of Rosemount. This improvement
consist of all concrete sidewalk within the cities right of way or declared as
part of the cities maintenance responsibilities. The project is located in
Section 29 within a perimeter of Chili Avenue thru Burma Avenue and 143rd Street
West thru Lower 147th Street West. The project is feasible from an engineering
standpoint.
The project includes approximately 8,000 square feet of the total 108,000 square
feet of concrete sidewalk in the City. These figures are approximately 7.5% of
the total sidewalk. The total estimated project cost is $40,658.
PART 1 - INTRODUCTION
1.1 AUTHORIZATION
On April 5, 1988 the Rosemount City Council, upon recommendation by the City
Engineer, authorized the preparation of an engineering feasibility report
for sidewalk replacement. This project has been designated as City Project
No. 186.
1.2 SCOPE
The purpose of this report is to determine the engineering feasibility of
this project based upon the review of the data available, and to make
recommendations and provide cost estimates for the replacement of severely
cracked and deteriorated sidewalk.
PART 1 - 1
PART 2 - GENERAL BACKGROUND
2.1 LOCATION
The project area is located in Section 29 and lies between Chili Avenue thru
Burma Avenue (West to East) and 143rd Street West to Lower 147th Street
West (North to South) as shown on Drawing No. 1
2.2 PROJECT AREA
All badly cracked and deteriorated concrete sidewalks within the project
area of the City of Rosemount. More specifically, the sidewalks on 143rd
Street West, 144th Street West, 145th Street West, 146th Street West, Lower
147th Street West, Burma Avenue, South Robert Trail, Cameo Avenue and Canada
Avenue.
2.3 EXISTING CONDITIONS
Staff surveyed the conditions of existing sidewalk within the project area
with respect to levels of cracking, spalling, pitting and differential
settlement of adjacent sidewalk panels. Staff classified them as light,
moderate or severe. It is the severe areas that Staff is recommending
repair or replacement of.
The project area is currently used as walkways for residential and
commercial purposes. For reasons of safety for our residents and liability
of the City, all areas of sidewalk which are unsafe because of being in poor
condition should be repaired or replaced.
PART 2 - 1
PART 3 - PROPOSED IMPROVEMENTS
3.1 SIDEWALK
The replacement and repairing of existing city sidewalks will be either by
mud jacking or complete replacement. Mud jacking will be used in areas of
differential settlement between sidewalk panels. The lower slab will be
raised to meet the grade of the adjacent slab. Sidewalks where severe
spalling, pitting or cracking exists will be completely removed and
replaced. The standard replacement will be 4" thick concrete, mix no. 3A32,
except for driveways where the thickness will be 6".

PART 4 FINANCING
4.1 COST ESTIMATES
Detailed cost estimates for all improvements proposed herein are included in
the Appendix of this report. These estimates are based on projected 1988
unit costs and include allowances for contingencies and anticipated overhead
costs.
A summary of these cost isasfollows:
Sidewalk Removal $ 8,847.00
Concrete Sidewalk 27,951.00
Mud Jacking 3,861.00
TOTAL $ 40,658.00
4.2 ASSESSMENTS
Staff recommends assessing the benefited property owners for a portion of
the sidewalk repair and replacement. Resolution No. 1971-29 was passed
October 5, 1971 establishing a method and procedure for billing for sidewalk
repairs and replacements. However, this resolution did not specifically'
state what portion of the costs were assessed. We are assuming 50 per cent.
Applying this procedure, to this project, would mean the City would pay 100%
of the concrete raising cost and 50% of the sidewalk removal and
replacement. The benefited property owners would pay the other 50% of the
sidewalk removal and replacement. See maps in the appendix for benefited
property owners. The total estimated City share would be $18,399.
This estimated assessment rate based on 50/50 cost sharing would be as
follows:
4' Wide --------------------- $ 6.00/l.f.
5' Wide --------------------- $ 7.50/l.f.
4' Wide Driveway ------------ $ 8.00/1.f.
5' Wide Driveway ------------ $10.00/1.f.
