NEW BUSINESS
Discuss Modified Design & Associated Costs for the Catalina Storm Sewer Project – City
Engineer Simpson stated as was discussed at previous meeting, the engineer’s estimate for
the original proposed storm sewer route was much more than original budgeted. The
2
original route was planned to go through Kurth Park. As design was nearing completion, we
found that the original cost estimate of $250,000 was going to be exceeded by more than
$250,000. GRAEF resized and relocated the proposed route straight down Cornell Drive at
their own cost. We also intend on keeping the existing pipe and making any spot repairs as
needed. There are two options - the first is a 21” pipe that will protect against the July 22,
2011 rain event for an estimated cost of $193,000. The second is a 24” pipe that will
provide added protection for a cost of $214,000. Ald. Soltysiak made a motion to move
forward with design and bidding of a 24” storm sewer and the additional cost for the
redesign. Ald. Werner seconded. Motion carried 3-0.
Recommend Award of Bid for Luehring & Hillview Drive Drainage Project – City Engineer
Simpson stated bids were received July 7, 2011, for the Luehring and Hillview Drives
Drainage Improvements and Road Reconstruction Project. We received six bids. Musson
Brothers was the low bidder. The low bid falls within our budgeted scope of which we
estimated $250,000, which also includes inspection and design work. Musson Brothers is a
large company and do State work. They have plenty of equipment and plenty of experience
for this type of job. Ald. Werner made a motion to award the Luehring Drive and Hillview
Drive Drainage and Road Project to Musson Brothers. Seconded by Ald. Soltysiak. Motion
carried 3-0.
Recommend Award of Bid for 2011 Road Improvement Program – City Engineer Simpson
advised bids were opened July 14, 2011 for the 2011 Road Improvement Program. We had
three bidders. Bids came in very low. Payne & Dolan was $477,890. The actual budget
was $625,000, which includes inspection and design work. Most of design work was done
in house. We will have extra money in this years budget to add additional road work. Ald.
Soltysiak made a motion to award the 2011 Road Improvement program to Payne & Dolan
and use staff discretion to bring the next on the list road projects with the balance of the
funds. Ald. Werner seconded. Motion carried 3-0.
Discuss City’s Position on the Tess Corners Creek Pond Project – The Mayor received a
letter from the City of New Berlin dated June 14, 2011. It discusses the Tess Corners Creek
Pond project that was originally discussed in 2000 per City Engineer Simpson. This project
was intended to be built in New Berlin and serve both New Berlin and Muskego. Essentially
the pond would act as water quality pond for New Berlin and water quantity pond for the City
of Muskego. This would reduce the storm event flows by approximately 37%. Back then a
grant was given, but expired and was revoked by the DNR. New Berlin backed out in 2004.
They said they would keep it in their plan and developers would build a plan in the future.
They thought by 2008 it would be part of a development area. Nothing has developed. New
Berlin is now saying that the reduction in total suspended solids is not cost effective for them
and that they do not feel that moving forward with the project is cost effective for that
reason. It would be a very costly investment, but one that the City may wish to make at
some point. Recommend staff to write a letter to New Berlin regarding considering mutually
beneficial projects.

From: Engineering Department, David Simpson, P.E., City Engineer
Subject: Tess Corners Drive Reconstruction Design Proposal (Janesville to
Woods)
Date: September 16, 2011
The pavement condition of Tess Corners Drive, from Janesville Road to Woods Road, is
quickly deteriorating. The roadway was rehabilitated in 2003 utilizing a subgrade
stabilization method that mixed fly ash with the existing soils. I was not involved in the
road program at the time, but records indicate that there was insufficient granular base
course material and potentially poor subgrade issues at the time that were not dealt
with properly.
Tess Corners Drive is now the worst pavement condition rated roadway in the City and
is deteriorating rapidly. Last year’s road program combined with this year’s program
will result in approximately $200,000 in excess funds that are proposed to be applied to
next year’s road program budget. This combined with the capital dollars budgeted for
the additional paved shoulders will result in a budget that should accommodate the full
reconstruction. Soil boring may determine that the budget may be greater than
anticipated, but that will not be known until after we begin design and soil borings.
I prepared and dispersed the attached Request for Proposals to seven different design
firms. All firms submitted proposals and these proposals were reviewed by a committee
of three staff members and two Aldermen. The proposals were s cored based on the
following:
(a) Consultant’s professional qualifications 5%
(b) Experience and qualification of your project team 30%
(c) Consultant’s present and committed work load 10%
(d) Project approach 20%
(e) Consultant Effort 10%
(f) Cost 25%
Not all reviewer’s scores were completed at the time of writing this memorandum, so I
will prepare the results and bring them to the Committee meeting.
Recommendation for Action:
Recommend awarding the design contract to the highest scoring company.

Woods Road including any necessary storm water management plans, minor intersection
reconfigurations. The design speed for Tess Corners Drive will be 40 m.p.h.
Both rural and urban typical sections are expected including continuous paved five foot wide
shoulders/additional width for pedestrian and bike users. It is anticipated that all reconstruction efforts
will be within existing right-of-way. The reconstruction will include the incorporation of the City’s
storm water management in accordance with Municipal Ordinance Chapter 34, and applicable WDNR
and MMSD permit requirements.
Meetings. The consultant shall attend or hold an Operational Planning Meeting (OPM) to discuss the
organization and processing of the services under the contract. The consultant shall meet with the City to
coordinate soils and sub-surface investigation work efforts. Monthly meetings shall be held to plan,
review, and coordinate the project with the City's staff. The consultant shall conduct meetings with
utilities having facilities on the project sufficient enough to ensure proper coordination. A Final Plan
Review Meeting with the City shall be held approximately 45 - 60 days ahead of the P.S. & E. submittal
date. The consultant shall attend the pre-construction conference as scheduled by the City.
Approximately three meetings shall be attended to explain various facets of the project to the common
council or other committee. One public informational meeting shall be planned and staffed.
Survey Work. Topographic information shall include, but not be limited to, edges of pavement,
driveways, and shoulders; all buildings and appurtenances; trees (with sizes in inches); woods or brush
limits; water courses and drainage facilities; and the location of all utilities.
Subsurface Investigations & Pavement Design. Subsurface soil investigations shall include approximately 20
soil borings to a depth of 10 feet below the existing surface. The borings shall be taken along the proposed
roadway centerline and/or driving lane centerlines and shall note the depth of and location of all soil layers,
bearing strength, and presence of ground water. All boring and sounding locations shall be referenced to the
project stationing and project elevation datum. The investigation shall also include the extent and classification of
wetlands. It should be noted that the soil borings and pavement design will be critical as the roadway was
rehabilitated in 2003 and is prematurely failing due to what is believed to be a either a failed subgrade
stabilization method (fly ash), a lack of base course material or a combination of both.

From: Engineering Department, David Simpson, P.E., City Engineer
Subject: Simandl Drive Lift Station Control Module purchase and installation
Date: September 16, 2011
At the September 20, 2010 Public Works Committee meeting staff requested that the
controls for the Simadl Drive Lift Station be replaced and relocated above ground.
Currently, the controls are located inside the control structure approximately 25 feet
below ground. During emergency operations, it becomes very difficult to operate this
facility because of the below grade controls (as was demonstrated during the July 22,
2010 storm event). The motor controls are at the end of their useful life and are in need
of replacement at this time, therefore this is the opportune time to relocate them above
ground.
Staff has been looking for the best way to relocate these controls above ground and have
determined that a prefabricated structure will provide all of the needs that this type of
conversion have. Starnet Technologies, Inc has worked with the City in the past and is
able to produce a prewired module that will deliver a cost savings to the City. City staff
will prepare the site and install the module. We will nee d to hire an electrician to
complete the connection of the controls to the station without interruption to the station.
The cost of the module is shown on the attached proposal for $53,000. Additional costs
will be for materials purchased by City staff to complete the site work and for the
electrical work (bids should be received by meeting time for this work).
Recommendation for Action:
Recommend purchase and installation of the Simandl Drive Lift Station Control
Module manufactured by Starnet Technologies.

Subject: Work Plan #3 Approval- Mitigation of PPII at Circle Drive and Richdorf
Drive/Racine Avenue Areas
Date: September 16, 2011
Background Information:
Two areas previously identified as high potential for flooding with impacts to the
sanitary sewer system are S75 W19020 Circle Drive and W191 S7608-7626 Racine
Avenue. These properties consist of one single family home and two 2-family
homes. Staff has been working with the MMSD to allow funding of the study and
design of mitigation measures to be granted from the allocated funding from the
MMSD through the PPII program. The attached documentation outlines “Work
Plan #3” that I have sent to the MMSD for their review and potential approval . I
am hoping to have an official opinion by meeting time.
Please refer to all attached documents to view the summary of work and scope of
services to be provided by Brown & Caldwell for these areas. The total estimated
cost is $41,947.00 and will be funded by the MMSD.
Recommendation for Action by Committee:
Approve the work plan as attached and recommend approval of an agreement (to be
reviewed by the City Attorney) to move forward with these projects.

Subject: City of Muskego Private Property Inflow and Infiltration (PPII) Reduction Work Plan #3 –
Mitigation of PPII at Circle Drive and Richdorf Drive/Racine Avenue Areas
Dear Jerome,
Please find attached the aforementioned Work Plan #3 for investigation work related to the City’s PPII
program. This work plan presents a strategic approach to investigating two specific areas which have
recurring drainage problems that are causing excess I/I by contributing storm flows in large quantities
against or into residences which then contribute high inflow and infiltration from private property sources.
The City has completed preliminary studies and desires to further those studies through this program to
refine the evaluation and mitigation recommendations of these two areas, culminating in designs and
related construction efforts to solve these problems. A complete project background, scope, and map of
the study area can be found in the attached Work Plan.
The City anticipates carrying out W ork Plan #3 using the District’s selected consultant team (Brown and
Caldwell/AECOM).
Please contact me at (262) 679-5686 or by email at dsimpson@ci.muskego.wi.us with any questions or
comments on this work plan.
Sincerely,
David Simpson

Municipality: City of Muskego
Type of Work: Primarily Planning and Investigation
Title: Private Property Inflow and Infiltration (PPII) Reduction Work Plan #3 – Mitigation of PPII at Circle
Drive and Richdorf Drive/Racine Avenue Areas
Background
The City of Muskego has experienced inflow and infiltration into its sanitary sewer system from a variety
of sources. Many of these sources are believed to be related to private property s ituations. Two
especially problematic areas are in the vicinity of Little Muskego Lake at Circle Drive and to the southwest
near the intersection of Richdorf Drive and Racine Avenue. A recent study by Graef characterized the
problem area at Circle Drive as such:
“This area is approximately 750 feet east of the intersection of Racine Avenue and
Richdorf Drive in a fully developed single family residential subdivision. The affected area
abuts Little Muskego Lake.
Stormwater generally flows easterly to this location from areas west of Racine Avenue
and from the north; eventually draining to both an existing 48-inch by 70-inch corrugated
metal culvert that discharges to Little Muskego Lake and to an existing 30-inch storm
sewer that also discharges to the lake.
The specific location where overland flooding has occurred during significant rain events,
events at and above the 10-year recurrence interval storm event, is the residence located
at S75 W19020 Circle Drive (Figure 4). It is believed by the City of Muskego that there
are other residences in the area that have experienced flooding that has been
unreported. Overland flooding has occurred at this residence; specifically, stormwater
runoff has drained into the garage of this tri-level home. This flooding within their
driveway has caused 4 feet of water in their basement during wet-weather events.
Stormwater that overtops Circle Drive in this location easily flows towards this garage
because the garage floor is at or below the adjacent roadway elevation.”
In addition, the City has received several complaints related to two properties at the intersection of Racine
Avenue and Richdorf Drive which, which as mentioned in the previous text, is just upstream from the
Circle Drive problem area. The Richdorf/Racine problem area situation it not too dissimilar from the Circle
Drive situation in that excess drainage from between private homes is causing water to enter buildings (in
this case, the lower level on the east side of the buildings) and causing the lower le vels to flood and enter
the sanitary sewer system through the flood drains. These drainage problem areas are clearly
interconnected and need to be considered together to try and resolve the drainage concerns and reduce
or eliminate the inflow and infiltration problem that exists. The Circle Drive has had flood insurance
claims but the problem persists. Sandbags are likely still present at the Richdorf/Racine homes in an
effort to keep water from the buildings. The accompanying map shows the relationship between the two
problem areas, buildings, pavement, and generalized topography and drainage in the area.
The City would like to engage the District’s selected consultant team of Brown and Caldwell/AECOM for
this effort. In general, the scope of work described in the following section will describe the effort to
review the alternatives and recommendations of the Graef study, consider improvements to the current
recommended alternative for Circle Drive and/or recommend additional alternatives, and to evaluate
alternatives and recommendations that also correct the drainage and I/I problem at the Richdorf/Racine
area. After this analysis, the project team will make a final recommendation on how to address the two
problem areas. After review and approval of the City and MMSD, the team will develop design plans to
correct the situation. Plans will be suitable for public bidding. Since the final recommendation is not
currently known, the level of effort for survey, design, and other services is estimated at th is time to
provide an approximate magnitude of the project. Following the acceptance of the recommended
solution, the level of effort will be re-evaluated and adjusted as needed to fit the scope of the design
needs.
Scope of Work
The Scope of Work for this Work Plan consists of providing investigation and design of two related and
connected drainage problem areas that are causing significant inflow and infiltration into the sanitiary
sewer system. The following basic steps for the Work Plan include:
1. Provide general project management and coordination activities.
2. Review the Graef study, computer models, and collect other relevant information related to the
site.
3. Conduct a site visit to review the problem area. Take photographs, review drainage systems and
patterns, and consider the recommended alternative as presented in the Graef report.
4. Conduct home inspections of three properties with known/reported impact from the flooding. (No
sanitary sewer lateral televising is currently proposed for this study.)
5. Meet with City staff to discuss potential alternatives for consideration.
6. Modify models provided by Graef for the expanded analysis of the Richdorf/Racine area. In
particular, it appears that the model did not include a drainage pathway between the properties
on Richdorf/Racine and a property to the east that appears to be contributing to the problem in
this location. This is not part of any designated or designed municipally owned drainage way.
7. Using available GIS data managed by the City (topography, utilities, parcels, etc) and the
aforementioned modeling evaluate the current Circle Drive alternatives and recommendation and
develop a set of alternatives that would address both problem areas. Alternatives may include
the following: floodproofing (or other related home modifications based on project findings
including home inspections), modifying ditches and culverts/storm sewers to increase
conveyance capacities, additional swales or berms to direct drainage around or away from
structures, and potentially other components (such as area/yard drains, sump pumps, etc).
8. Develop a brief memorandum reviewing the problems and alternatives.
9. Meet with City staff (and potentially MMSD) to review the alternatives and selected a
recommended approach for design.
10. Attend one neighborhood meeting to discuss the project with affected property owners.
11. With approval of the City and MMSD, proceed to design the recommended solution components.
Design includes the following anticipated components:
a. Survey the areas impacted by the recommended solution. This assumes project
components at or near the two problem areas that will result in grading, vegetation
restoration, and potential culvert or storm sewer modifications. It also assumes the need
to develop temporary construction easements for at least 5 properties. (Cost estimate
developed as based on assumptions as noted.)
b. Develop plans and specifications suitable for bidding. (Design level of effort similar to
extent as noted above.)
Develop a basemap for the design using the survey collected for this project with
other existing data. We will utilize the size and invert elevation data, determined from
our modeling efforts for storm sewer, ditch, berm, and other infrastructure
improvements.
If necessary, flood proofing improvements such as glass block windows or other
items will be detailed or added as notes to the plans depending on the complexity of
the design component.
Present a draft set of documents to the City at 60% completion for review and
comment. Review comments will then be incorporated into a final set of bidding
documents, which will be produced and delivered to the City of Muskego for
distribution to prospective bidders (If requested, AECOM can provide the added
service of plan distribution). The Contract Documents will consist of the “front end”
documents, instructions to bidders, bid form and technical specifications. It is
assumed that AECOM will develop technical specifications and an initial set of “front
end” documents will be provided by the City (If requested, AECOM can develop the
“front end” documents as an additional service.) Drawings will be produced at a 24” x
36” size and 15 copies will be provided to the City. AECOM will also apply for a
Prevailing Wage Rate Determination as required by the Wisconsin Department of
Workforce Development.
At this point, it is uncertain if WDNR, or other permits or approvals will be required.
However, because of the proximity to the lake, depending on the amount of grading
or structure work, permitting requirements may be triggered. An allowance of $5,000
is set aside for permitting related activities.
c. Bid Support and Construction Services (Currently not included in this Scope of Services)
Schedule and Estimated Timeline for Expenses
The City desires to conduct the planning/analysis and field work in 2011 before snow impedes survey,
with design to follow during the winter and construction in early spring.
Since the City will be utilizing the District’s PPII Consulting Team (Brown and Caldwell/AECOM), it is
anticipated that the District will see expenses related to this Work Plan starting approximately 30 days
after initiation of the work plan (first invoice assumed to be early November based on an October 3rd start)
and final expenses approximately 30 days after completion of the construction and final acceptance of
contractor work. Assuming that project construction begins March 5th with a 6-week construction period,
the construction would be complete about April 13th with a final payment request coming May 15th or early
June depending on the final acceptance and payment approval process. The actual timeline may vary
depending on the final design components selected, contactor schedule, and approvals processes.
Budget
A budget estimate of $41,947 is established for this project and allocated to the District’s Consultant
Team (Brown and Caldwell/AECOM). Breakdown for this work is as follows:
1. Develop and Manage Work Plan - $2,192
2. Planning - $9,135
3. Inspection - $655
4. Design - $15,291
5. Implementation - $0
6. GIS - $0
7. Technical Assistance (survey/permitting) - $14,674
8. Public Involvement (M03063E03) - $0
Data Collection
Home inspection data will be collected following the Home Inspection Manual and protocols developed
under Work Plan #2.
Field survey and other project data will be collected in accordance with normal engineering and survey
standards of care.
Goals and Anticipated Outcomes
It is the City’s goal to inspect the impacted properties, review and update existing reports, and ultimately
develop an approach to relieve the drainage situations that are causing storm water to enter these homes
and contribute significant quantities of inflow into the sanitary sewer system. It is anticipated that success
would be proven by the lack of storm water directly entering the affected homes and a corresponding
reduction in private property inflow into the sewer system during significant storms.
Reporting
The City will provide a summary report to the District consisting of the number of homes inspected,
provide a copy of the summary memorandum that documents the problem areas, evaluates alternatives,
and develops recommendations. The City will also provide a copy of the design plans to the District.

MMSD PRIVATE PROPERTY INFILTRATION AND INFLOW REDUCTION PROGRAM
MMSD CONTRACT M03044P02
The City of Muskego commissioned and completed a study investigating
sanitary and storm water related inflow problems throughout areas of the city.
A second study identified two storm water related inflow problems that
appear can be mitigated through a design solution. The two areas are:
Circle Drive and Racine Avenue/Richdorf Drive Private Drainage Projects.
Each of these two private drainage
projects has unique circumstances in which overland storm flows are
entering properties and causing inflow sources. Each has one or more
potential mitigation measures that can be applied.
Property inspection would be a component of the project. The city would like
assistance with the evaluation, survey, inspection, and design of these sites.
