Memorandum
TO: Mayor & City Council
Mark McNeill, City Administrator
FROM: Bruce Loney, Public Works Director
SUBJECT: River District Trunk Sewer Line Reconstruction - Phase ill,
from Adams Street to Fuller Street, Project No. 2007-1
DATE: April 18, 2006
INTRODUCTION:
Attached is Resolution No. 6410, a resolution ordering the preparation of plans and
specifications on improvements to the River District Trunk Sewer Line Reconstruction -
Phase ill, from Adams Street to Fuller Street, Project No. 2007-1.
BACKGROUND:
On October 2, 2001, the City Council ordered the preparation of a feasibility report for
the River District trunk sewer, essentially from Adams Street to L-16 (Met Council lift
station).
The feasibility report has been completed and the report was accepted by Council on
January 21, 2003. Attached is Resolution No. 6410 , which orders the preparation of
plans and specifications for Phase ill of the River District Sewer Line Reconstruction,
from Adams Street to Fuller Street. Funding of this project will be out of the Sanitary
Sewer Fund, as a sanitary sewer replacement project and Storm Drainage Fund for storm
water improvements. Since no assessments are involved, a public hearing is not
necessary.
This project was initiated by the spring flood of 2001 and the high III the City of
Shakopee experienced. Engineering staff did an estimate on the III cost and determined
$135.000.00 for this flood. The new rules from FEMA are such that excessive III in
major flood events are not reimbursable any longer. Also, in the Phase ill project area,
the existing sanitary sewer trunk line is extremely close to the riverbank and is in danger
of being undermined by riverbank erosion. Pictures of the river and location of the sewer
pipe are enclosed with this memo.
Currently the sewer flows on Lift Station No. 16 have increased from 900,000 gallons a
day on April 5, 2006 to 1,500,000 gallons a day from April 7-13, 2006. The city pays the
MCES $1.55/1,000 gallons for treatment of sewage.
On Phase ill, from Adams Street to Fuller Street" it is proposed to reconstruct and realign
the sewer main away from the river as much as possible. In some segments, relocation
may be difficult and expensive. Riverbank stabilization may be necessary to protect the
sewer if relocation is not feasible. During final design, construction options will be
analyzed and reviewed for cost effectiveness. The proposal from Bonestroo includes an
alternate route report to analyze future alignments and costs versus riverbank stabilization
or a combination of pipe relocation and riverbank stabilization. Bonestroo's proposal is
to provide the design services at a maximum fee of $106,904.00, which includes an
allowance of $12,000.00 for soil investigation work.
Staff is also requesting City Council action on authorizing an extension agreement with
Bonestroo, Rosene, Anderlik & Associates, Inc. to prepare the plans and cost analysis for
relocation ofthe pipe versus riverbank stabilization.
ALTERNATIVES:
1. Adopt Resolution No. 6410.
2. Deny Resolution No. 6410.
3. Authorize the appropriate City officials to execute an extension agreement with
Bonestroo. Rosene, Anderlik & Associates, Inc., to prepare plans and specifications
for this project.
4. Do not authorize an extension agreement with Bonestroo, Rosene, Anderlik &
Associates, Inc.
5. Table for a specific reason.
RECOMMENDATION:
Staff recommends Alternative No.1 and No.3, to adopt Resolution No. 6410, so that the
sanitary sewer relocation design can begin for construction. Also, it is recommended to
execute an extension agreement with Bonestroo, Rosene, Anderlik & Associates, Inc. to
prepare the plans and specifications and provide the design engineering expertise for
relocation of pipe or riverbank stabilization or combination of both.
ACTION REQUESTED:
1. Offer Resolution No. 6410, A Resolution Ordering Plans & Specifications for the
River District Trunk Sewer Line Reconstruction - Phase ill, from Adams Street to
FuIIer Street, Project No. 2007-l.
2. Authorize the appropriate City officials to execute an extension agreement with
Bonestroo, Rosene, AnderIik & Associates, Inc., in providing design engineering
services, as necessary for this project, and as per their proposa1.

Desi~n Flow
Bon~stroo will revisit the design flowpr:pjeclipn~ in the City's Comprehensive Sewer Plan to
confirm the proper capacity and .size of the replacement interceptor. We will meet with City st.afHo
review future development plans for the areas ttibutary to this interceptor system. Rahr.Malting has
a connection to. the City sanitary system within the project area. It is. our understanding that Rahr
may be coming off the City system in the near future. We will meet with City staff and, if
necessary, coordina,te a, meeting with Rahr.Malting.and the. City to determineJu{ure flows that
should be anticipated from the R~hr facility,
Interoeptor Replacement
. The Phase II Interceptor .(Segment 3) will need to be replaced and up-sized, The 2003. Feasibility
RepOlt fo.r this segment no.ted that the existing line has "sags and poor joints as well as manholes that
are \;Jnder ground co.ver." Infiltration/Inflow (III) has been identified as a major problem that steals
cap&city for future growth and has a major impact on the cost of 9perations. In addition, access for
operations and maintenance is extremely difficult due to pOl1ions of the pipe near an unstable
riverbank, surrounded by heavy vegetation and downed trees, or routed through areas with soft soils
and wetl~nds.
The Bonestmo team will conduct additional investigations of the existing;line and aqjacent lands to
determine the most effective options. to reco.nstruct the sewer. At least three alternative alignments
il)dudingtheLeveeDrivero\lte will be evaluated?nd summarized i.n a AIternativeRoute :Report
that willbe'v,re$ented to'City staff and Council for revi~w prior to. the start of preliminary design.
The capacity of the P:hase II improvements will be designed to handle cun.entand future flows
generated in the service area up to the 6.7 cfs (4.3 mgd) de$ign capaCity of thePbase 1
impro:\lements. Since this will be a replacement of an existing 'interceptor S1'stem, the upstream and
downstrea~ eJev~tionsarefixed. The Phase II Interceptor system will have an upstream invert
elevation of approximately 706;0 and. a downstream invert elevation of700.7.
B.one.stroo wiWevaluate constfl;1ctipn techniques including open-out excavation using a trench box
and alternative'trenchles$ technologies such .asjaqkiijg or directional drilling in the constticted areas.
Oue to the weak organic soils anticipated alo.ng the alignment, Bonestmo will evaluate subcutting
the unsuitable soils and replacing these soils with .granular backfill; both with and without geotextile
to provide a stable foundation for the new pipe.
Bonestl'Oo will evaluate the following types of pipe material for the replacement interceptor: FRP,
PVC and HDPE. These pipe matetials feature fewel' joints than l'einfol'ced concrete pipe, are
resistant to COll'Osian and are. known for their resistance to 1/1. Bonestroo will also evaluate lined
reinforced concrete manholes, as well as, monolithic fibergl~ss manholes,
Continuous sanitary se,wer service l!1ust be, provided by the Phase II Interceptor; A scheme to keep
the e~istinginterceptor in operation until the replacement interceptor can be placed in service, or
bypassing depending upon the final location of the new sewer~ will be developed during desigl) and
incotpdr.Efted into thebiddittg documents. Temporary 1;>ypass pumping and remporary connections
will be .specified and detailed, asnecessaty.

Sanitary Sewer Laterals
At least three existing sanitary sewer laterals will be disconnected from the existing intel'ccptorand
recQnnectedt6 the replacement interceptOl:. Bonestroowill research whether additional lateral
sewers exist. Bonestroowill specify and detail how these disconnections andreconnections are to
be accomplished. It;s likely that a pOItion ofthe III being canted by the existing intei'ceptor is
enteri~gthesyste:m through defects in theclateral $ewers. Bonestroo will evaluate the lower pOltion
of each of the laterals to determine whether they should be replaced tofurtl1erexclude liT. If a
de.cision is.made to replace the lower portions of the sanitary laterals, Bonestroo will prepare the
necessary specifications, drawin,gs,and details. .
Sanitary Sewer Services
It is unknown whether existing sanitary sewer services from homes and bllsinesses are connected
directly to the existing. Phase II interceptor. Bonestroo will research whether any services are
connected. If so, Bonestroo will prepare specifications, drawings, and details for disconnecting
th(fSe services from the existinginterceptonmdrecQnnecting them.to. the replacementinterceptor.
Also, these s~rvices may bethe source ofsignificant volumes of III. Bonestroo will compare the
elevation of the services to river stage during flood events. If the services are subject to hi gh water
head during flood events, it may be beneficial to replace the. services to exclude III. Ifi! is
deteffilin.ed. to'be beneficial to r,eplace the services, Bonestroo will. prepat'e specifications, drawings,
and details for the replacement ~ervices.
. Storm SewerOutfalls;
The stol'mwater outlets in the project area will need to be re.constructed as. part of the Phase II
prdject.Bo'nestroo will evaluate ,each situation and developstormwater outlet designs that will
convey stoffilw~terf1ow \0 the river side of the interceptor while effectively dissipating energy in
the. stonnwater 3;l)d:mitigatil1g erosion potential. The stonnwater design details will be incorporated
.info the bidding documents. .
Restoration
DesignwilIil1clude site restor~tiot:1 jn areas thlit are impacted~ It is our understanding that the City
has already had discussions with the COE on Section 14 funding available for river bank
stabilization for the project. It is assumed that design of any river bank stabilization will be
provided hy COE. Bonestroo will incorporate COE river bank stabilization design into the City
sanitary sewerproject. We wi.lI coordinate; additional meetings with the COE if deemed necessary.
Downed trees, rubbi~b and tr~sh will be removed from the .site as part of the construction contract.
Installation of the new pipe will require some ofthe trail system to be reconstructed, Bonestroo will
coordinate replacement trail design with MnDNR and the City Parks Depaitment.

Reconstruction of the City's River District Trunk Sanitary Sewer line from Rahr Malting
f to Scott Street.
~ SITE
LOCATION
Justification:
The River District Trunk Sanitary Sewer needs reconstruction in order to maintain the
integrity ofthe system from inflow/infiltration.
Other Comments:
Current system is in need of repair, which leads to inflow and infiltration problems during
river flooding. Existing concrete pipe and manholes are not adequate to withstand the hydraulic
pressure from high river elevations. It may be advantageous to delay project until Rahr Malting
completes their wastewater treatment plant.
Operatina Costs:
Reduction in inflow/infiltration sewer treatment costs and possible penalties from EPAlMPCA.
