Mainstreet storm Sewer
11th to 13th Avenues
Proposed Action.
Staff recommends adoption of the following motion: Move
that Council adopt Resolution 92-26. Resolution Approving
Plans and Authorizing Bids, Mainstreet storm Sewer Between
11th and 13th Avenues.
Overview.
When the issue of redevelopment of the Suburban Chevrolet
site first arose, staff reviewed the site for any potential
utility conflicts, similar to the reviewal process used with
the Bursch Restaurant property. Indeed, it came to light
that a large 60 inch storm sewer was located in the vacated
alley of the 1100 and 1200 blocks south of Mainstreet.
Furthermore, a building addition at Suburban Chevrolet was
allowed to be constructed over a portion of the storm sewer
pipe.
Aside from addressing the problem of a structure built over
the storm sewer, staff immediately perceived benefits to
relocating the pipe to Mainstreet. with that in mind RLK
Associates were engaged to study the feasibility of
relocation and to develop a proposal to carry out the
construction.

Analysis.
0 What are the benefits?
Other than remediating the problem of a Suburban
Chevrolet structure situated over the storm sewer,
staff sees several advantages in a relocation project:
I. storm sewer systems of this size are better
located within roadways for ease in maintenance
access.
2. Relocation of the pipe into the roadway has
the potential to reduce intersection ponding on
Mainstreet.
3. Mainstreet reconstruction west of 11th Avenue
necessitates major trenching for other utility
work and this affords an opportunity to take
advantage of that fact.
4. storm sewer located in the approximate middle
of a site limits building pad options. Relocation
greatly enhances development potential for the
Suburban Chevrolet site.
0 What are RLK's recommendations?
The proposal and adjunct plans call for relocation of
the 60 inch pipe to Mainstreet from 11th Avenue to 13th
Avenue during Mainstreet utility construction scheduled
for this spring. Existing storm sewer in 11th Avenue
north of the parking ramp would be relaid to redirect
street and ramp runoff northward to Mainstreet.
Several new catch basins would be constructed in
Mainstreet and existing structures connected to the new
pipe. The large pipe would then be installed in 13th
Avenue south of Mainstreet and be connected again to
the existing system flowing into Nine Mile Creek. The
existing pipe adjacent to Suburban Chevrolet and the
American Legion Post would be bulkheaded and abandoned.
RLK recommends the public bidding process for the
purchase of the new pipe and structures and negotiation
with C.S. McCrossan, the prime contractor on Mainstreet
reconstruction, for a price to install the storm sewer.
The attached plans and bid documents for Council
approval reflect that recommendation. Council at this
juncture would approve material purchase by the bidding
process. Staff could approach Council with a change
order to address pipe and structure installation costs
at a future date.
0 What is the estimated cost and how will construction be
funded?
RLK estimates the purchase of pipe and structures at
roughly $~04,545. The negotiated price for
installation is estimated at an additional $87,365.
The total cost, including overhead, is estimated at
$204,400.
The current storm sewer utility is hard pressed to
underwrite these construction costs. However, TIF
funds are available and staff recommends this as a
source of funding.

MEMORANDUM
DATE: December 11, 1991
TO: Tom Harmening, community Development Director
Jim Kerrigan, Director of Planning
Dick Koppy, RLK & Associates
FROM: Lee Gustafson, Public Works Directo~
SUBJECT: Suburban Chevrolet Storm Sewer
It came to my attention this week that a large storm sewer
pipe located behind the Suburban Chevrolet building should
be relocated to Mainstreet if the city wanted to maximize a
redevelopment project on that site. It was furthermore my
understanding that the city was going to strongly consider
relocating this pipe to Mainstreet during the 1992
Mainstreet construction in order to take advantage of this
street being torn up.
These ideas were discussed at the Public works staff meeting
this week. I thought I would pass along the comments of the
meeting to all of you so you would be aware of our initial
reaction.
1. Good idea to have large pipes such as this within the
roadways, and not behind buildings for ease of access.
2. If the pipe is relocated to Mainstreet, an analysis
should be completed to maximize the benefits of moving
this pipe. The most significant benefit would be to
further reduce intersection ponding on Mainstreet.
3. Probably the only negative reaction is that the storm
sewer fund is broke, and alternative funding for this
project would be needed.
Let me know if you need further information on this matter.

SUBJEC'l': SUBURBAN CHEVROLET STORM SEWER
---------------------------------
Attached is the letter from Dick Koppy which provided a couple of
alternatives on undertaking the relocation of the Suburban
Chevrolet storm Sewer into Mainstreet. Mr. Koppy recommended,
primarily due to cost ,saving measures, that the city consider
using Alternative No. 2. The concern which I had with using this
alternative pertained to whether or not the city could legally
utilize this process due to the large change order which would
need to be negotiated with C.S. McCrossan with respect to the
installation of the storm sewer pipe.
I have discussed this matter with Jerre Miller, City Attorney.
It was Mr. Miller's opinion that Alternative No.2, involving a
change order with McCrossan, was acceptable due to the following
reasons:
0 It seems that we can link the relocation of the storm
sewer to the Mainstreet project.
0 Feels it is a logical method to deal with the storm
sewer problem.
0 The storm sewer relocation project is very similar to
being part of the Mainstreet project.
I would request that we discuss this matter further with respect
to the initiation of a project to relocate the storm sewer to
Mainstreet. I would suggest that perhaps we should establish a
meeting between you and I as well as Jim Gessele and Jim
Kerrigan. Please contact me and let me know of your thoughts
regarding this matter.

SUBJECT: STORM SEWER - SUBURBAN CHEVROLET SITE
---------------------------------
Attached is a map of the Suburban Chevrolet site which
illustrates the location of the 60 inch storm sewer which runs
east/west through the site. You will note that the storm sewer
is located in the approximate middle of the site. Based upon a
very rough estimate from RLK and Associates,itis expected that to
relocate the storm sewer onto Mainstreet between 11th Avenue and
13th Avenue wilr cost approximately $210,000 plus other overhead
costs.
Due to the opportunity which the Mainstreet reconstr~ction
project provides to relocate the storm sewer, and due to the
City's interest in redeveloping the Suburban Chevrolet site, I
have taken the liberty of asking RLK Associates to provide a
proposal to the city for engineering services to prepare the
necessary plans and other support services to undertake the
relocation of the storm sewer. The proposal will include an
estimate for the cost to prepare plans and specs including a
bidding process and not including a bidding process. I would be
interested in hearing your thoughts on possibly obtaining a
proposal from another engineer to provide these same services to
the city.
It does appear we have some time to deal with this issue,
including how this project could be funded, as construction
between 11th and 13th Avenues is not scheduled to occur until
after the Raspberry Festival. However, I felt it appropriate to
begin the planning process now sp that we are ready to deal with
the issue when the time comes.

City of Hopkins

Hopkins, Mn. 55343
Dear Mr. Harmening:
You requested a proposal on the Suburban Chevrolet storm sewer from
RLK Associates. Earlier in December at a City staff meeting we
discussed the problems that this pipe creates. Our focus in
reviewing the solutions has been to place the storm sewer pipe in
Mainstreet during the period this coming construction season that
Mainstreet will be reconstructed. Lee Gustafson's memorandum dated
December 11, 1991 provides adequate background on the storm sewer
problem. It is attached for your review.
We have focussed on two alternatives that could be pursued, depending
upon the City's decision, I will explain each of the alternatives in
the following section and then present a short cost estimate,
Alternative #1 -- Normal tlOesiqn-Bid-Construct" method:
utilizing this approach, RLK would commence design activities in
February. The feasibility study and preliminary design would be
completed by February 15, 1992. The report could be submitted to the
City Council at that time for approval to complete final design plans
and specifications. These should be completed by March 7. Bids
could be advertised and opened on March 27, with the award of bid
made by the City Council at the first City Council meeting in April.
Construction would. take place during the construction season of 1992,
Our estimate of cost is shown below if this method is used.
S5 connee-tion to old system $1,000
Remove storm manholes 650
Construct new storm manholes 6,000
Place 60" RCP sewer (0-8' deep) 159,600
Fill existing sewer pipe with sand 21,000
Bulkhead existing manhole 1,500
Salvage castings 150
Sub-total 189,900
10% Contingency 18,900
Total Construction Cost 208,890
Design/Construction Manage/Survey Fee 8% 16,710
Total Project Cost $225,600
Alternative #2 -- Desiqn/Build Construction Manaqement approach:
U.sing this approach, RLK would begin the design phase in February
with the feasibility study being completed by February 15. As in
'. Civil Engineering · Transportation · Infrastructure Redevelopment
. I <:lnrlC:::,.,::lnA Ar,.,hitp.,.,tIJrp. . Cnn~trllrti/"\n M<:ln",.,=~~~'
Page 2, Suburban Chevrolet Storm Sewer Proposal, Tom Hannening
the previous alternative, the feasibility study could be submitted to
the City Council on February 18 or the first meeting in March for
authorization to proceed into final design and construction.
However, the difference with this proposal is that we would negotiate
a price to install the storm sewer with C.S. McCrossan, the
Mainstreet utility contractor. The City would purchase the storm
sewer pipe and manholes directly from a concrete pipe manufacturer
and deliver it to the project site at the commencement of this phase
of the utility construction. It would be advisable to use the public
bidding process during the purchase of the pipe, but a supplemental
agreement procedure with the Mainstreet construction project is
recommended. The following estimate of cost is estimated if this
method is used:
Purchase of the 60 " RCP storm sewer pipe $67,000
Purchase of manholes 2,000
Installation of Pipe and Manholes by McCrossan 75,000
Fill existing storm sewer pipe with sand 20,000
Sub-total 164,000
Contingency 10% 16,400
Total Construction Estimate 180,400
Design/Construction Management/Survey Fee 6.5% 11 ,700
Total Project Cost $192,100
These costs have been reviewed by several sources, so they have some
degree of reliability. The big question mark concerns the design,
since this has not been approached at this time. Of the two methods,
I think the second alternative has the most opportunity of achieving
the biggest cost savings to the City. My guess is we may be able
to lower the cost by another $20 to $25,000.
In any event, both alternatives are within twenty percent of one
another. This represents the estimated range of costs the project
should fall within, If you have other questions, concerns or you
wish to have me prepare a sketch of the design alignment, please
advise.
Sincerely,
RLK ASSOCIATES, LTD.
