RE: Possible 1988 Improvement Project Report
Following is a synopsis of projects proposed for 1988 construction with estimated costs, including
22 percent for City expense. The projects are being proposed due to direction from the Council,
requests from adjacent affected property owners, for maintenance reasons, and /or based on
engineering considerations.

Subdivision Agreement (1986)
b.) School Road from 7th Ave. N.W. to California St. as $
requested in a letter from Mr. Tyrone Relland. A
portion of the cost is eligible for Municipal State
Aid Funds because of the street being wider and thicker
in structure than a local street. City Cost is MSA
eligible.
c.) Campbell Lane from approximately 300 feet north of $
Hilltop Lane to Connecticut Street in Clark's 2nd
Addition. Paving the east -west portion of this street
may need to be delayed until utility installation is
completed to the McClure property north of Campbell
Lane and west of Connecticut St., the subdividing of

2nd Ave. S.W. from Franklin St. to Dale St. The County $ 457,500.00
has budgeted $150,000 as its share of the project cost.
State Aid regulations require that for a minor
arterial, which is the present functional
classification of 2nd Ave. S.W., with projected traffic
from 5,000 to 10,000 vehicles per day, the curb to curb
width be 48 feet with parking on both sides, or 38 feet
with parking on one side only. Present street widths
vary from 40 feet to 46 feet. Any street widening
would result in removing a number of boulevard trees.
Rate to equally allocate cost between assessable
frontage and non - assessable frontage is $61.00 per
front foot, in which case the City Cost would be
$91,000.00. Assessment rate is $38.00 per front foot
for City Cost shown. City Cost is eligible for
Municipal State Aid Funds. The County has budgeted
$150,000.00, as its share of the project cost, which
will reduce the City Cost to $1759000.00.

to the school district frontage on the west side of
Glen Street because that distance is the long dimension
of the parcel. If the Council chooses to assess the
long school frontage less 1501 abutting Washington
Avenue, and also, 2nd Avenue S.W., the City Cost would
be $131,300.009 assuming an assessment rate of $38.00

assessment rate of $45.00 per front foot for 3,326
feet of frontage. City Cost is eligible for Municipal
State Aid Funds.
Dakota Rail intends to set a dining train on their
tracks on the north side of 3rd Avenue N.W. between
Main Street and Glen Street. They will likely be
requesting angle parking in the street. The
assessable frontage that was determined does not
include any frontage of railroad right -of -way.

North therefrom,,which is eligible for State Aid
(Deferred $138,700.00)
Funding and possible MN /DOT Funding through a
. cooperative agreement. It is assumed that 15x9 which
is $64,155.00, of the cost can be funded by MSA and
MN /DOT cooperative agreement. Assessment rates are
then estimated to be $0.033 per square foot for trunk
storm sewer, and $0.164 per square foot for trunk and
lateral storm sewer to achieve zero City Cost. See
accompanying map for approximate assessment areas.
It is noteworthy that parcels abutting 3rd Avenue N.W.
were assessed $0.065 per square foot for a storm sewer
-
project in 1975. Other properties in the drainage area
=
were not reviewed for previous assessments. There
presently are deferred assessments on parcels abutting
3rd Avenue N.W. from 1968 for sanitary sewer and water

main that could be activated.
k.) Frontage Road South Side of T.H. 7 from School Road
$ 108,900.00 $ 86,300.00
to approximately 900 feet West of School Road,
reconstruction of the frontage road, and providing a
connection to T.H. 7 about 900 feet West of School
Road as requested by Super America. MN /DOT approval
must be obtained for roadway connection to T.H. 7.
City Cost shown is based on estimated assessable
,frontage as determined from present and possible

rM. Director of Engineering
RE: Surfacing Les Rouba Parkway
At the direction of several members of the City Council and the Director of
Parks and Recreation, this department has studied Les Rouba Parkway for the
purpose of determining a cost to surface the roadway. The dust and rough
uneven roadway surface results in maintenance problems and an environment
that is contrary to the predominantly park and recreational useage.
The roadway was also studied to determine potential geometric and safety
4 improvements.
Roadway improvements
The unpaved portion of Les Mouba Parkway from the inplace pavement of Mater
Street to the frontage Road along T.H. 7 is one mile in length. In May,
1987, this department obtained twelve soil borings along the roadway.
Information obtained from the borings is used in designing pavement structure,
thicknesses and to estimate earthwork that may be required for removing
unstable or undesirable soil in the roadway.
A preliminary proposed typical section is attached. Bituminous pavement
2 -3/4" in thickness with 12" of gravel base beneath should be sufficient
pavement structure for the soils encountered. Geotextile fabric would also be
used beneath the gravel base to alleviate the influence of unstable soils.
The recommended pavement width is 24 feet. Such a width will not encourage
high speeds, as would be the tendancy with wider pavements, but will allow for
twc wav traffic and the occasional passage of a recreational vehicle cr
trailer an two wart traffic. A cavemen= narrow=_. tsar. 24 feet is not
recommended because such a roadway would pzcbel., sustain. damage to the edge
_`.e cavement due _c traffic consistently dr' °inc on. or near the edge.

On the northwesterly and of Les Kouba Parkway, the paved roadway would be
widened to 3E feet with curb on both sides. The pavement would also be thicker
to accommodate commercial traffic.
Drainage
To the maximum extent feasible, drainage will be provided overland.
Installation of storm sewers would increase the project cost, and our
preliminary study shows that the majority of drainage on the project can be
accommodated on the surface, thereby negating the need for storm sewer. The
notable exception is at the nortbwast corner of the wildlife sanctuary where a
culvert must be installed across the roadway that will drain into the
sanctuary ponds. This department will pursue the acquisition of an easement
from the sanctuary that will permit drainage onto the sanctuary property.
Geometric improvements
we reco®nend that the following improvements be made in conjunction with the
surfacing project. The improvements are sham schematically on the attached
drawing.
1. Access to the intersection of 3rd Avenue N.N. and Glen Street via Les
xouba Parkway should be closed. The intersection provides for east -west
and north -south traffic flan and Les ltouba parkway being a second leg on
the west side of the intersection and at an acute angle creates a safety
problem. Closing access to the intersection will tend to reduce speeds on
Les Kouba parkway vest of the intersection where people gather to watch
wildlife and the scenic river area.
2. The east access to Les Kouba Parkwav could be constructed across the
railroad tracks at either James Street or at Lind Street. The latter
presently has a vehicular crossing at the ttacks but it is narrow and in
poor condition, and it should be replaced.
Whichever crossing is chosen, the portion of Les Kouba Parkway between the
crossing and Glen Street would serve as a parking area. This area is
-
presently a popular site for people to park and enjoy the natural setting.
3. At the intersection of Les Kouba Parkway and the Frontage Road alona T.H.
7, Les Kouba Parkway would be realigned so as to meet the existing roadway
openine onto T.H. 7. To accomclis`: the realignment, the roadwav would be
_ved westerly onto the Hutchineor. ^-c -o, prorert_'. A riaht- cf-way easer*nt

highest traffic volume was 400 vehicles per day. Althouah no actual observation
was done regardinc tae percentage of traff ;.c that is through traffic with no
oarticular interest in the park or the wildlife area, it is safe to assume that
a certain percentage of the traffic stream fits such a description. With the
park and recreational type of setting, through traffic should be discouraged.
The City Council has expressed concern for the deteriorated condition of 3rd
Avenue N.W. from Main Street to the Hutch Computer site, and bas directed this
department to propose a street reconstruction project for 1988. However, such
a project would be the subject of discussions at two public hearings, after
which the Council would take official action, either ordering construction of
improvements or deleting the project. Also, the transportation plan calls for
the ultimate connection of 3rd Avenue N.W. at Hutch Coapyter to the T.H. 7
Frontage Road where it presently terminates east of the victories Inn.
Right -of -way easements are needed for the Frontage Road extension, and the
needed right -of -ray is presently the sajor problem in realizing a project for
the connection.
When the 3rd Avenue N.W. - T.P. 7 Frontage Road is ultimately completed, a
direct route will be provided for through traffic rather than the circuitous
parkway. Through trips will be greatly reduced, if not eliminated.
Estimated Project Cost
The estimated total construction cost for the project is $266,700. With the
usual addition of 22 percent for City Expense, the total project cost is
$327,800. To reduce the financial impact, the project could be scheduled for
more than one year. Two alternatives follow.
Alternative 1:
In 1988, construct aggregate base, curb and gutter and bituminous
surfacing frgm Luce Line Trail to the T.H. 7 Frontage toad, and excavate
and backfill unstable areas complete with geotextile fabric and
aggregate base. Estimated construction cost is $122,100; estimated
total cost is $149,000.
In 1989, complete excavation, placing geotextile fabric, aggregate base,
and bituminous sui_fac:nc. Estimated construction is $146,690;
estimated total cost is 5178,800.

• Whatever schedule of constrjctior is chosen, we recommend that areas of
unstable soils, which total approximately- 150. , feet in lencth, be excavated
and backfilled the first year. By so doxnc, sufficient time will elapse,
even if it is only one winter, to enable an analysis as to whether the planned
subgrade treatment is adequate.
sumary
The one mile length of Les Rouba Parkway is currently a maintenance problem
and dust resulting from the existing gravel surface is not conducive to
promoting a,clean environment and to the useage of adjacent park and
recreational areas. The plan contained herein will provide a safe roadway at
an economical cost, based on conditions at the site. When a decision is made
on a plan of action, a recommendation will be presented to the City Council.
if additional information is needed or if there are suggestions, please call

pear Mr. Xjonaas:

As we discussed previously. the City of Hutchinson may be reconstructing 2nd
Avenue S.w. from Franklin Street to Dale Street, a distance of about 2,840 feet
in 1988. The entire project would require approval of the City Council before
plans would be prepared for a contract. Meanwhile,itis safe to asI me aware that
the City Council will request Canty Part P i t Prof e
of the County's policy for participation in the center 24 feet of the roadway
construction. That construction cost is estimated to be $130,000. In addition,
storm sewer reconstruction may be required at an estimated construction cost of
nty
=50,000. The State Aid Office will likely determine the Perco Cage of Counonld
participation in the storm sewer, but for budgeting purpo
be adequate. Also, State Aid does allow 10% for preliminary engineering and
st for construction engineering, for which we would likewise request County
participation.
Please take the appropriate steps to assure that funds will be available for
the County's share, should this project be authorized to proceed. if you have
any questions, or if additional information is needed, please call me at

August 6, 1984
Hutchinson City Council
Hutchinson, Mi. 55350
Dear Council Members:
The purpose of this letter is to urge the Council to recommend that
steps be taken to remedy a faulty storm sewer situation at Gioebel Fixtures.
At the time we built our 25.000 square foot addition in 1978 -79, we
were informed by Juul Contracting that the storm sewer in Lake Street
might not be deep enough to adequately drain our premises. Juul installed
two 10" connections to the Lake Street storm as best as they could under
the circumstances. Since that time, our outside loading dock fills up
with water with any substantial rainfall. (This dock at Lake Street
should not be confused with the new indoor docks constructed this past
winter.)
The problem is normally not so bad insofar as damage to property as
long as a truck is not sitting in the below-grade loading ramp. If a
truck happens to be in the ramp during a dowtpoor, water can rise over
the hood of the cab; since we frequently leave trucks parked in the ramp,
this is likely to happen at any time.
This past June, however, we had a torrential rain which totally filled
up the ramp. The water then literally gushed up through our dock leveler - -
board and flooded the entire back end of our building. Because of some
quick- thinking and acting people we managed to 'sandbag" the inrushing
water to keep the flooding to a minimum.
The net result was water in a fourth of our plant (up to 2" deep).
Fortunately we had people in the building when the water first started
coning in who got anything that could be damaged by water up off the
floor. Since our main materials are wood. you can see our concern. The
enclosed pnotos illustrate this point. We do not believe that there is
anything we can do ourselves to eliminate this problem; the problem is
w: ;h tte storm sewer in Lake Street.
It is cur understanding that +Then the huge story sewer project on

• in talking with city officials and Juul Construction we also
understood that it was always intended to correct the problem some -
time. We feel that the time is now - before Lake Street and Roberts
Road undergo resurfacing. What will it take to get this project off
the back- burner?
We would appreciate an answer as quickly as possible and will give
the City any assistance necessary to get the project underway. Thank
you.

Dear Gary,
REF: Enclosed Copies of Previous Correspondence
Since August of 1984, nothing has really changed in the storm sewer
situation here at the plant. Fortunately we have not had any 9" rainfalls
like Bloomington had, but again this scorning we had some flooding in our
building (for the third time this year).
Some things have happened in regard to this matter:
a. The project was assigned to Marlow Priebe for study.
b. I went over the situation with Juul Construction.
c. The 16" storm sewer section in Roberts Road was replaced from the
St. Anastasia parking lot to Larson Street with new 20". (The 16"
was nearly plugged by tree roots).
d. We have decided to better equip ourselves with a permanent "flood
cart" that has all the necessary equipment to do battle with
incoming water. (Which only protects us during occupied bours.)
None of these steps have yet solved the problem. My suggestion at this
time is to reassign the new City Engineer to the project.
I. talking to Juul Construction, they suggested that during a heavy rain to
pull: a manhole cover in Lake Street to see if it is full. I did this
mvself a while back during a moderate rain storm and found the storm sewer
near;: a . k? believe it is only a 14" and we alone have two 10" going

Meeting opened at 9:00 AM by Chairman DuWayne Peterson
II. Chair called on Ron McGraw to explain a 'buy -out" proposal of Burlington Northern
Railroad by Dakota Rail, Inc.' He explained to the committee the need for local match funding
required by the state will match dollars to "buy -out" the railroad. In order to get the most
favorable price from the Burlington Railroad a financial package acceptable to all parties
must be finalized by Dec. 31, 1987. McGraw emphasized to those present that any
suggestion of financial commitment on the part of local parties should be communicated to
him as soon possible.
III. The chairman then brought up the item of financial proposals concerning the Main Street
revitilization project.
City engineer, Gene Anderson, explained the scope of one part of the project, the installing of
new water entrances to all lots and sprinkling of all basements in the targeted area.
(4th Ave. So. to the river and Hassen St. to Franklin St.) see enclosure *1
Ken Merrill, City Finance Director, briefed the group on the status of various city funds. He
indicated the Revolving Loan Fund would have available in 1988 the amount of $500,000 as
set forth in the Revolving Loan Fund document. He also indicated the Sewer and Water Fund
was a possible source of funds. Consideration needs to be given as to future commitments
from the fund previously established based on sources and uses of the monies in the fund.
Bernhagen reviewed with the committee the general scope of the revitilization project. He
indicated that in order for commercial and apartment revitilization to take place, a
favorable funding package must be implemented in order to not strain already strapped
budgets on the part of the business and building owner.
Based on interest to date of 42 building owners there could be upwards of $260,000 of need
from the Revolving Loan Fund and $350,000 from the Grant. In addition, $100,000 from
the Revolving Loan Fund has been previousl y committed by the City Council for energy need.
Those dollars will also be used in the overall uptown revitilization.

The following is a possible funding proposal under a Small Cities Development Program
Grant:
Total available under the grant $1,400,000
Grant
1. Water entrances & sprinkling basements
$920,000 $ 500,000
11. Commercial & Apartment Rehab
$650,000 385,000
III. Hotel Rehab to LMI Apartments
& Commercial Rehab $800,000 400,000
$2,359,000
Administration 50,000
Project Director (2 years) 65,000
$1,400,000
The committee discussed the need to continue the Revolving Loan Fund as 'Revolving" rather
than depleting the fund by grants. They also considered certain parts of the water project
that would normally come directly from the water fund with no future assessments
($140,000). Review of dollars needed for the commercial, apartment and hotel portions of
the grant was also reviewed. Members were informed that of the commerical, apartment and
hotel grant dollars in a period of 20 years over $200,000 will be paid into the Revolving
Loan Fund.
The following was agreed to by all present as a recommendation to the City Council on the use
of various city funds for the Uptown Revitilization Program:
Water entrances & sprinkling $920,000
Grant
Revolving Loan Fund (not to exceed $200,000) 21% $ 193,200
SCDP Grant 55% 506,000
City Water Fund 24% 220,800
100% $ 920,050
The state has indicated that a percentage of the grant can be used toward payment of the water
entrances and sprinkling of those buildings out of compliance of the code only. Other funding
needs to be found for all other buildings in order to treat all owners on an equal basis to have
access to water for regular consumption and sprinkling.
Pat Stall man of Citizens Bank, expressed a strong need to erase the dark cloud over all the
property in the uptown area because of fire code /sprinkling problem.
There being no further business the meeting adjourned at 11:00 A.M.

Dear Gary:
I'm enclosing herewith a copy of a proposed resolution governing the
implementation of the committee.
I would like to offer the following comments with regard to the
proposed committee.
First, I believe the resolution should specify that the committee's
responsibilities are limited to review and that the committee is
acting in an advisory capacity only. It is my understanding that at
this time the city is not interested in enacting mandatory rules and
regulations on this subject. If I am not correct in this regard,
please advise.
Second, I have avoided specifying in detail the manner in which the
committee will operate since I'm not certain those decisions have
been made yet. I assume the Mayor can make the appointments with
the appropriate recommendations of downtown merchants, city offi-
cials and so forth.
Third, I am still waiting to hear from Duluth and I have contacted
them and asked them to send me as soon as possible the necessary
documents.
Gary D. Plotz

MEMORANDUM
DATE: November 24, 1987
TO: ✓Mayor and City Council Members
FROM: Director of Engineering
RE: REPORT ON COPPER WATER SERVICE CORROSION AND EROSION
During at least the past ten years the city has experienced a problem with
is copper water services leaking due to the pipes becoming thin or porous.
Although incidents have occurred throughout the city, the most notable
occurrences have been on Main Street at the following locations:
- The former North Star Gas Station in 1977
- Post Office at 245 Main St. S. in 1981
- Lang's Wig Shop at 2 Main St. N. in 1985
- Mike's Mobil at 105 Main St. N in 1986
- Gold Coin at 35 Main St. N. in 1987
In judging pipe samples obtained from the most recent leak at Gold Coin, it
appears that the city is experiencing a corrosion and /or erosion problem. In a
report prepared for the influent (inflow) at the waste treatment plant and of
domestic sewage discharge at various points in the city's sewage collection
system showed abnormally high concentrations of suspended copper in the sewage.
Concentrations were of such magnitude in domestic sewage that, given allowable
copper concentrations in the treatment plant effluent (outflow) as established
by the Minnesota Pollution Control Agency and the efficiency of the treatment
plant in removing suspended copper, no suspended copper can be allowed in the
industrial sewage, thus placing a burden on industries to attempt to remove all
copper from its effluent. The elevated concentrations of dissolved copper were
not present in samples obtained from the treated water at the water treatment
plant, and are evidence of the erosion and corrosion of copper water services.

Memo - 11/24/87
Sources of Information
In an effort to determine causative factors of the apparent erosion/corro-
sion problem, various sources of information were consulted. Among them are
"Copper For Hot and Cold Portable Water Systems ", a Penton /IPC Reinhold Publica-
tion; "Conditions Contributing to Underground Copper Corrosion ", a paper
published in the American Water Works Association Journal; "Mitigating Copper
Pitting Through Water Treatment ", a paper published in the American Water Works
Association Journal; "Mitigation of Copper Tube Cold Water Pitting By Water
Treatment ", a paper prepared for the 1984 International Corrosion Forum; and the
"Copper Water Service Corrosion Study" prepared for the City by RCM Associated,
Inc. Also the problem was discussed with local contractors and personal obser-
vations were made at Gold Coin.
Potential Factors Causing Erosion /Corrosion
Some or all of the following factors may be contributing to the loss of
copper in water services.
1. Agressive soils, usually soils high in organic content. This is not a
problem on Main Street where sand, gravel, or small amounts of clay are
prevalent, which seldom possess the properties associated with corrosion. A
high water table, also not present on most of Main Street, is also needed to
allow corrosion to occur.
2. Varying types of soil through which a copper service is installed can
cause an electrochemical corrosion to occur. However, since in the vast
Majority of city projects the soils are similar in a given area, and backfill
• operations require uniformity of soils in the pipe zone, the effects of varying
soils are all but eliminated.
3. Stray direct current, such as from high voltage direct current
transmission systems, welding facilities and cathodic protection systems, can
flow in the earth through paths other than those intended. Should stray
currents flow onto an underground structure such as a water line, corrosion loss
would occur at the point where the direct current leaves the water line and re-
enters the earth. Although such corrosion would not result in copper being lost
to the water supply, this type of corrosion could have contributed to the
problem at Mike's Mobile where the underground fuel tanks have a cathodic
protection system.
4. Alternating current action on the corrosion of copper pipe is not yet
well understood. Investigators disagree as to whether, and to what extent,
corrosion is enhanced in copper pipes by alternating current. But many believe
that it is reasonable to assume that the commonly used practice of grounding
electrical systems to underground copper water systems can lead to corrosion.
Unfortunately such a practice is presently required by the state electrical
code. Corrosion by this occurrence would be an the pipe exterior and would not
contribute to high copper concentrations in the water.
5. Workmanship and materials used during pipe installation can effect
longevity. Residual burrs left on pipe seating surfaces can cause turbulence in
the water flow that may erode the pipe. Certain soldering flux compounds can
have a corrosive effect on copper. Copper material itself could have
manufacturing deficiencies that could cause problems under certain circumstances
2
Memo - 11/24/87
but over all the industr considers copper to be an excellent material due to
its immunity to corrosion.
6. The concentration of dissolved carbon dioxide in the water can have a
detrimental effect if above a certain threshold. In the case of the city's
water supply, dissolved carbon dioxide is two to three times greater than levels
considered to exist in nonaggressive waters. Decreasing dissolved carbon
dioxide would decrease pitting corrosion on the interior of the pipe.
Pit initiation, investigators believe, seems to be connected with
intermittent use where the system remains stagnant for several hours, like
overnight in a residential situation. This tends to reinforce the findings of
the Pace report in which high copper concentrations were found in domestic
sewage outflow. Installations where there is a continuous demand for water are
less likely to experience pitting corrosion.
7. Water hardness will not usually determine whether a water is corrosive,
but if the level of hardness is slightly greater than the level the water can
hold some of the mineral hardness will form on the pipe interior. Investigators
believe the coating to be beneficial in deterring pitting corrosion and erosion
because of the protective barrier it forms.
8. Excessive flow velocity of water within the pipe can result in
deterioration of the pipe. Water whose chemistry may not be quite sufficient to
cause a problem at a low velocity may create a problem at a higher velocity.
The protective scale normally observed in copper pipes exposed to stable water
can be eroded away by fast flowing water leaving the underlying copper surface
unprotected. The pipe can then literally erode away.
• Although erosion and corrosion of copper pipes can be caused by any one or
a combination of these factors, and possibly more, the City's problem would seem
to be due to inordinately high concentrations of dissolved carbon dioxide and by
high flow velocities. Several past repairs, including that at Gold Coin, showed
the pipe badly deteriorated in the five or six feet nearest to the water main,
while the balance of the water service was in good condition. The portion of
the water service near the main is subject to turbulent flows which, when
combined with the water chemistry can and have eroded and corroded away the
pipe.

Inspector does not believe that
Proposed Solutions
The concentration of dissolved carbon dioxide should be reduced to make the
water less aggressive. One attempted solution was initiated at the water treat-
ment plant this summer, that being a better more thorough means of aerating the water
prior to it entering the distribution system. In so doing the intent was to
release excessive amounts of dissolved carbon dioxide. However improved aera-
tion had little if any effect. The addition of caustic chemicals to the water
at the treatment plant will result in a reduction of dissolved carbon dioxide.
Included in the water department's 1988 budget request was $26,000. for equip-
ment to store and to feed caustic into the water. The estimated annual chemical
cost at present day cost is $84,000., which translates to about $1.09 per capita
per quarter assuming average useage. An alternative solution to the aggressive
Memo - 11/24/87
water problem is the addition of phosphates to the water which would neutralize
the electrcal nature of the corrosion process. Equipment to store and to feed
the chemicals should cost less than ;5,000., and the chemicals themselves about
$8,000. per year. The basic difference between the processes is that the first
mitigates corrosion at the water treatment plant while the second process acts
to minimize corrosion throughout the system. Inbalances in flows and usage
throughout the system could make the second alternative less dependable, al-
though the estimated annual cost is about one -tenth that of the caustic chemical
alternative.
A second solution to the problem is to reduce the velocity of flow in the
water service to a level that would be unlikely to cause pipe deterioration.
One way of so doing is to install larger diameter service pipes. The
engineering department began installing 1" diameter water services to homes on
construction projects in 1987. Previously the standard service size was 3/4 ".
Summary
The copper erosion /corrosion that the city is experiencing is a complicated
problem. But from all indications, reducing system velocities and altering the
chemistry of the water will, if not cure the problem, greatly prolong service
life.
We will continue to investigate this problem in an effort to determine any
other possible causes, and whether other potential solutions could be effected.

DATE: November 25, 1987
TO: ,*ayor and City Council
FROM: Director of Engineering
RE: Downtown Water Distribution Project
As was recently presented to the Council by the Executive Director of the
Hutchinson Community Development Corporation, in conjunction with the
downtown revitalization project, we recommend that water service pipes to
all buildings be replaced, due to the corrosion and erosion problems
experienced on Main Street in the past ten years. A portion of the project
cost could be funded through a Small Cities Development Program Grant and
the balance by the Water Fund, assessments and/or the improvement bond.
• A preliminary plan and cost estimate has been prepared for installation of
new water services to buildings within the project area which is bounded by
the river on the north, Fourth Avenue South on the south, the west side of
Hassan Street on the east, and the east side of Franklin Street on the
west. The goal of the plan is to install sprinkler services to all buildings
not presently served thusly and whose basements are larger than 1500 square
feet, as required by the Life Safety Code, a portion of which is attached.
However, the scope of the plan was enlarged to provide sprinkler service to
all buildings and buildable sites in the project area, thereby foregoing the
potential need to excavate Main Street in the future to do so.
Costs were determined for installation of 4" water services -from the main in
the street to the building. Services would generally be installed side -by -side,
within three or four feet of each other, and would approach buildings thusly in
hairs in line with the common wall of the buildings. Near the buildings the
services would be redirected so that one pipe would be installed to one building
and the other pine to the adjacent building. The 4" service would function as
a sprinkler service. A connection would be made to the sprinkler service just
outside of the building and a shut-off provided for the domestic water service.
Both service pipes would be installed through the foundation wall or into the
basement, as the case may be, for connection by the property owner. A waiver
of tresspass or similar document will be needed from each owner to allow
installation into the building. It is unlikely that the point of service thus
provided will match the existing point of service, so it can be assumed that
at the very leas'_, the domestic water service will need to be reconnected inside
the building. Exhibits "A" through "D" show the proposed installations in the
street. One disadvantage of installing services in the street is the disruption
of traffic. An advantage to this method of installation is that the sidewalk
will be maintain<_d _'or pedes=trian traffic the majority of the time.
is
Downtown Water Distribution Project
November 25, 1987

Costs were also determined for installing water mains in the sidewalk on both
sides of the street, cross connecting those mains to the Main Street water main
with services installed to buildings and buildable sites as described above.
Exhibits "E" through "G" show the proposed installations in the sidewalk. An
advantage of installing the mains in the sidewalk area is that vehicular traffic
can be maintained for the majority of the project duration, albeit one lane in
each direction, which will increase congestion problems. Some disadvantages of
this alternative are disruption to pedestrian traffic for lengthy periods of
time, and increase water main footage with associated maintenance, while the
Main Street water main exists nearby.
Accompanying is a cost estimate for each alternative, and for a combination of
the two alternatives, which includes the least cost of each. Also, included is
the estimated cost for installing water mains on certain side streets contiguous
to Main Street. Those streets are Second Avenue North from Hassan Street to
Franklin Street, Franklin Street from First Avenue Northwest to Second Avenue
Northwest, Washington Avenue from Main Street to Franklin Street, Second Avenue
Southwest from Main Street to Franklin Street, and Third Avenue Southeast from
Hassan Street to Main Street. In addition to providing sprinkler service to
establishments for system looping, thereby enhancing reliability of the
distribution system. All estimated costs include 22% for City expenses.
There have been discussions in the past of removing the sidewalks along Main
Street as part of the revitalization improvement and constructing decorative
sidewalk, such as with paving brick or granite slabs, or of providing an
exposed aggregate surface. If that were to occur, the sidewalk replacement may
be totally grant eligible, in which case the estimated water main cost could be
reduced as follows:
Estimated Total Sewer and Water Cost
Less Estimated Sidewalk Reconstruction Cost
Estimated Net Sewer and Water Cost

Street and
Under Sidewalk Sidewalk
$ 798,200 $ 717,400
$ 59,900 $ 24,400
S 738,300 $ 693,000
Presently, a number of buildings fronting on Main Street are served from the water
main in the alley west of Main Street. We recommend that in conjunction with main
Street revitalization and improvement project, those buildings be reconnected to
services that will be provided from the Main Street water main or from a side
street main, as the case may be. In so doing, the City would be able to ultimately
abandon the alley water mains.
mains in the alleys present problems from the standpoint of maintenance and main
or service freeze-ups. These problems are magnified in the Central Business
District where gas mains, telephone cables, and-electrical conductors are alreadv
present in the alley, making any need for maintenance excavation difficult.
Installation of new mains in t--- alleys alleys is nct recommended for the same reasons,
and because t::ne nrcximity of building on either side or both sides of the alleys
confine available working space and the buildings themselves or their foundations
could sustain damaae during construction.

• One block of sanitary sewer must be reconstructed or rehabilitated. The sewer
is on Main Street from Second Avenue North to the river. Costs incurred are
evidently not eligible for grant funding.
An estimate of cost for sprinkling only the basement of the building in the
project area is attached. A cost near the lower estimated figure could be
expected if all of the owners hired one contractor, or possibly two or three,
to do the work. On the other hand, if each owner hired a different contractor,
the cost would likely be near the higher figure.
The downtown water main improvement project could be completed in 1989.
Suggested sources of funding are the small cities grant assuming the City's
application is accepted, the water fund, the revolving loan fund, and the
improvement bond.

RE: Northwest Water Tower Inspection
Attached for your information is a summary of the tank inspection performed
by the firm of AEC Engineers & Designers. Section 2 of the summary shows a
cost estimate for the project. Some of the items of work can be performed
by the City, including preparation of plans and specifications and
construction inspection, and some of the interior and exterior structural
repairs. By so doing, the City could save $20,000 to $25,000 in estimated
cost.
Due to the condition of the inplace coatings, this project should be done
in the next one or two years.

ELEVATED WATER TANK INSPECTION .,. _ .:
Hutchinson Client: City of
Northwest Tank Location: County Road 12 - Fifth Avenue
Tank Description: • MMG Sino - edestal Spheroid
Type of Coatings: Interior: Coal Tar Epoxy
Exterior: Alkvd Paint System
Inspected by: Jack Kollmer
Date of Inspection: October 13. 1987
INSPECTION RESULTS
1.0 Conclusions and Recommendations
The following repairs or modifications are recommended:
1.1 Interior Structural
1.1.1 Remove by air arc gouging or cutting torch the
approximately twenty -one (21) 4" x 6 rigging
brackets located on the tank shell near the equa-
tor. Many of these brackets have been broken off
by ice damage, or are bent or flattened against
the tank shell. The broken brackets have left a
jagged weld scab mark on the tank shell and are
rusting. See Photo Nos. 2,3,and 4. Repair the
scab marks on the tank shell per Surface Prepara-
tion Requirements as found in Appendix C.
1.1.2 Install a tank bowl drain plug and piping system
connected to the overflow pipe to allow ease of
cleaning and draining the tank bowl area. See
Photo NO.5.
1.1.3 Weld or epoxy caulk unwelded bottom side of three
(Z) stiffenerz located on the drywell tube. See
Photo No.e. This is required to nalt corrosion in
this a-ea.

i
• 1.2 Interior Coating
1.2.1 we recommend that after structural repairs are
completed, the entire reservoir surfaces be pro-
perly prepared and the coating replaced with a
light-colored polymide epoxy system, similar to
Rust -Oleum Series 9500 Epoxy, Koppers Hi- Guard, or
the Tnemec Series 20 Pota -Pox Epoxy.
1.3 Exterior Structural
1.3.1 Repair minor spalling to concrete grout under the
tank base plate. See Photo Nos. 9 and 10.
1.3.2 Caulk porosity in the base plate around anchor
bolts to halt rust and corrosion from water trapped
in this corrosion pocket. See Photo No.10.
1.3.3 Install locking devices on roof access manways.
The Minnesota Health Department recommends that
"Fencing, locks on access manholes, and other
necessary precautions shall be provided to prevent
trespassing, vandalism, and sabotage."
• 1.3.4 Install circular handrailing system on tank roof
around drywall tube and roof manway. See Photo No.
S. The Minnesota Health Department recommends:
"Railings or handholds shall be provided on-eleva-
ted tanks where persons must transfer from the
access tube to the water compartment."
•
AEC
1.3.5 Install one (1) 24" round AWWA hinged ventilation
roof manway as directed by the engineer, similar to
BMT Standard 0-014 or equivalent. See Appendix B.
This vent is required to provide proper ventilation
during abrasive blasting and coating.
1.3.6 Remove restriction at overflow pipe opening and
install overflow pipe screen. See Photo Nos.11 and
12. Use corrosion resistant one -in -four mesh
screening.
i
•
0
1.4 Exterior Coating
1.4.1 Due to age, chalking, deterioration, lack of inter -
coat adhesion, and lack of resistance to mechanical
damage (rocks) and graffiti, the entire exterior
coating should be removed and replaced with an
epoxy /urethane coating system, similar to those
manufactured by the Koppers or Tneme� companies.
2.0 Engineering COS Estimates 4
2.1 Interior structural repairs r $ 6.600.00
2.2 Interior coating - wet area v 9f �Q_ru�0.00
Type of coating - epoxy system
2.3 Interior coating - dry area
None required 1.04 $ 0
O
2.4 Exterior structural repairs C 'e- $ 5.200.00
2.5 Exterior coating - dry area
Type of coating - epoxy /urethane system 44.500.00
2.6 Engineering specifications and 18.500.00
inspection fee
2.7 Estimated Total Cost $107-800.00
2.8 Estimated job duration 5 - 6 weeks.
2.9 These cost estimates represent the current pricing struc-
ture. If you plan to proceed with the coating of this
tank, the sooner the specifications are ready for bidding,
the more competitive the bids will be.
AEC
• 3.0 Future Inspection Schedule
3.1 The tank painting should be first inspected within the
warranty period, and every three years thereafter.
4.0 Life of G ^� *� ^a System
4.1 with the recommended paint system and a regularly
scheduled tank inspection and maintenance program, the
tank interior and exterior should not require complete
recoating for the next fifteen to twenty years.
