1. PROJECT SUMMARY
In January 2018, the Common Council approved the sale of approximately 33 acres of the former Lakeshore
Golf Course to the Oshkosh Corporation. Shortly thereafter, Council chartered a new path for Lakeshore,
determining that the golf course’s remaining 70 acres would be redeveloped as a community park.
Beginning in January of 2019 the City of Oshkosh initiated a three-part planning process for Lakeshore Park. The
first steps in that process included data collection, meetings with city staff, and site analysis. This process of
collecting quantitative site-specific information was followed by a robust public outreach process consisting
of an online Polco survey and a Public Visioning Meeting. These channels were leveraged to ascertain subjective
input, and the community was invited to help shape big picture goals for the Lakeshore Park Master Plan.
Based upon public input, it became clear that the community’s vision tended toward a park focused on passive
recreation and characterized by restored native habitats and ecosystems; a place where park users could engage
with nature. Those who participated in the public engagement process also clearly articulated the importance
of art, history, culture, and community in shaping the form and function of Lakeshore’s next iteration.
Together with input from Parks Department Staff, the Advisory Park Board, the Pedestrian and Bicycling
Advisory Committee, and the Sustainability Advisory Board, the community’s feedback was translated
into three Conceptual Design Alternatives. These initial concepts varied with respect to: required monetary
investment; strategy for handling and ultimately reorganizing/restoring existing water bodies; scale of
flexible/open gathering spaces such as lawns and plazas; locations, types, and sizes of buildings; parking
locations and counts; pathway network hierarchy and extents; shoreline restoration treatments; water
access; landform manipulation; and means of acknowledging the site’s important cultural history.
Feedback from the Advisory Park Board, and ongoing coordination with Parks and Engineering Staff resulted in
a hybrid plan that borrowed preferred plan components from each of the three Conceptual Design Alternatives.
This hybrid plan reimagines the former Lakeshore Golf Course as a community destination with two distinct
halves. The West Park is introverted and focused on a Great Lawn, and its earthworks mitigate freeway noise
and focus the attention of park patrons on the network of restored and connected ponds rather than traffic
and Oshkosh Corporation parking areas. The largest of these earthworks is also leveraged as a lookout and a
location for an art installation in an effort to create an iconic community identifier at Oshkosh’s front door.
LAKESHORE PARK MASTER PLAN | OSHKOSH, WISCONSIN4
The East Park is more developed and extroverted, focused on Lake Butte des Morts and extending to physically and
programmatically connect to and complement its neighbors, Mary Jewell Park and Rainbow Memorial Park. This
half of the park includes the catalytic phase one improvements, including a four-season multipurpose building for
community and private events, a splash pad, plaza, and water access by way of a fishing/personal watercraft pier
and a cobble beach. The East Park includes parking areas that are intended to serve its neighboring parks, and it
includes an area dedicated to recognizing and honoring the site’s rich cultural history, and a nature play playground.

HISTORY
The first step in the Lakeshore Park master planning process was an inventory and analysis of the property’s
unique features, defining characteristics, and practical limitations. The planning team processed city-
provided files, county GIS data, NOAA bathymetry, related city planning documents, and other sources to
build a comprehensive picture of Lakeshore’s potential and understand the nuance of the project site.
While a great many sets of data and maps were processed and reviewed with Parks Department staff, the
most relevant analyses concerned the site’s history, its physical characteristics, and its water resources.
2. SITE ANALYSIS
Figure 2.1 Archaeological sites around the Fox and Wolf River confluence. The map above is derived from Figure 2.39, "Previously
reported archaeological and burial sites along Lake Buttes des Morts," in Archaeological Investigations at 47WN0049 (BWM-
0210) Golf Course, Winnebago County, Wisconsin.
LAKESHORE PARK MASTER PLAN | OSHKOSH, WISCONSIN6
The Fox River, and the lakes around its
confluence with the Wolf, have long held
significance to Native Americans and early
settlers thanks, in part, to the travel route
the Fox affords. Prior to the development of
railways and roadways, the Fox provided an
almost continuous water route connecting
Lake Michigan to the Mississippi River
by way of Green Bay, the Lower Fox, Lake
Winnebago and Lake Butte des Morts,
the Upper Fox, and the Wisconsin River.
The 13 ponds that were part of the former
golf course appear to be remnants of a
"slough" or "meander scar" created by
the Fox River. Prior to the construction
of the Doty Island dams in 1850, Lake
Butte des Morts was a combination
of wetland and braided river channels
similar to the aerial view of a portion
of the Upper Fox shown below.
Figures 2.3 and 2.4. 1938 aerial photograph of Lakeshore Park (top); the Fox
River near Berlin, Wisconsin (bottom) .
Like many sites scattered around the confluence of the Wolf and Fox River systems, the project site was
important to pre-settlement Native American cultures and holds significance for those communities
today. Archaeological sites at the margins of Lake Butte des Morts are shown in orange on page six. The
Lakeshore Park property contains portions of one such site, which is primarily located on high ground at
the northeast corner of the Oshkosh Corporation property but extends east into the northwest corner of
the East Park. This site has yielded both artifacts and burial features, some of which were inadvertently
encountered and documented but most of which, presumably, have been preserved in place.

Lakeshore Park resides at the confluence of two watersheds – the Wolf River and The Upper Fox River Watersheds.
These watersheds drain vast portions of the state and contribute to the quality of the water in Oshkosh’s
lakes. While the Wisconsin DNR considers the quality of Lake Winnebago’s water "fair" for a shallow lowland
lake, and rates its aquatic ecosystem health as average (see map on page nine), it none-the-less recognizes
that the lake system is highly vulnerable to climate change related influences (see map on page nine).
The scale of the project site, the fact that it has extant water bodies that are former meanders of the Fox, and the
fact that the project site possesses 4,550 linear feet of Lake Butte des Morts shoreline all suggest that Lakeshore
Park can play a significant role in contributing to the health of the watershed, especially if it leads by example.

SITE CHARACTER + USER EXPERIENCE
500 FT
The existing park’s character, and one’s experience of the park, is still very much defined by its
former life as a golf course. Existing vegetation types are very limited, with a pastoral golf course
landscape (mown turf and trees) yielding to delineated wetland at the margins of the existing
ponds, and feral brush along the west half of the park’s Lake Buttes des Morts shoreline.
Due to the former golf course layout and the locations of trees that once framed fairways, one’s attention
and the orientation of the park’s view corridors parallel the waterfront rather than engage it.

The site’s proximity to the Interstate 41 corridor has a significant impact on the experience of the West Park. During
the team’s initial site walk, their route through the park began by scaling a berm at the south edge of the West Park;
the noise at that location was intense and had a significant impact on the team’s experience of the space. However,
as the team descended the berm and walked north to the West Park ponds, the freeway noise became much less
intrusive and no longer dominated the experience of the park. This first hand observation, tied to the site’s topography
and its relationship to the adjacent freeway, informed the development of an earthworks concept for the West Park.

3. PUBLIC PROCESS
The project’s robust public engagement process has utilized three avenues – an online Polco survey, a Public
Visioning Meeting, and public dialog at all committee and board meetings. The Polco survey was opened
for input on May 17th, 2019, and collected data for two and half weeks from over 420 individuals, closing on
5 June. For each survey taker, the line of questioning was intended to solicit data on user demographics,
current park use, and desired park program. The Polco results summarized and excerpted here align
with input collected on sticky notes, comment cards, and boards during the Public Visioning Meeting.
Specifically, the community clearly and collectively articulated a desire for a passive recreational park
built around restored habitats and ecosystems and focused on art, community, and cultural history.

4. MASTER PLAN
Figure 4.1. Lakeshore Park Master Plan.
LAKESHORE PARK MASTER PLAN | OSHKOSH, WISCONSIN18
The Lakeshore Park Master Plan
reflects the community’s vision
for a primarily passive park that
affords parkgoers an opportunity to
experience nature. It is comprised
of an East and West Park connected
by the Riverwalk and a restored and
renaturalized Lake Butte des Morts
shoreline along the north edge of the
Oshkosh Corporation property, and a
green corridor at the southernmost
boundary of the Oshkosh Corporation
property. Both halves of the park
leverage the existing golf course
ponds, restoring and reshaping
their margins and linking them
with wetland corridors to form a
functioning ecological backbone for
the park. The relatively homogeneous
golf course topography is resculpted
to reinforce this wetland spine,
define space, orient views, and
mitigate the presence of the
adjacent freeway. At the West Park
the improved topography takes
the form of significant earthworks,
which are intended to block noise
from Interstate 41 and views to
the Oshkosh Corporation parking
lot and create an opportunity
for an iconic hilltop feature –
an art installation, overlook, or
other community identifier.

Large lawns are distributed throughout the park to provide flexible, functional space for picnicking,
events, play, and sport. Sweeping pathways provide a hierarchy of accessible routes through
the park, creating multiple loops for walking, running, accessing the park’s shoreline and
restoration areas, and connecting to amenity buildings, parking areas, and regional trails.
The Master Plan includes five structures. The West Park contains a hilltop overlook structure at the west
earthworks, two open-air picnic shelters at the Great Lawn, and a restroom building at the southwest corner
of the park. The East Park contains a single, larger multipurpose building. Unlike the West Park structures,
this is a conditioned, four-season building sized to accommodate a large multi-purpose room for public
and private functions. The East Park building also includes public restrooms and storage space.
Parking for the West Park is accessed via Rath Lane; it includes space for approximately 40 cars. Parking for
the East Park is distributed across three areas. A main lot, at the north end of Punhoqua Street, serves the
four-season building, accommodates approximately 80 vehicles, and includes two drop-off zones. A smaller
+/- 20-car lot off of North Eagle Street, near the lift station/restroom building at the northern edge of Mary
Jewell Park. And approximately 20 parking spaces are included off of Veterans Trail, at the north end of Rainbow
Memorial Park. These latter two lots are strategically located to serve both Lakeshore Park and the contiguous
Mary Jewell and Rainbow Memorial Parks, whose ballfields are not currently served by off-street parking.
Additional park amenities include: an occupiable, stepped shoreline revetment at the shoreline connector north of
the Oshkosh Corporation property; a nature play playground north of Mary Jewell Park, a splash play area adjacent
to the four-season building, a fishing and personal watercraft pier near the north end of Punhoqua Street; and a
combination cobble and perched sand beach where the Lakeshore Park and Rainbow Memorial Park shorelines meet.
An area dedicated to the recognition of the park’s cultural history is located at the northwest corner of the
East Park, near the boundary between the Oshkosh Corporation property and the city-owned parkland.

5. PHASING + BUDGET TARGETS
The implementation of the Master Plan is coarsely portioned into five phases.
Phase One is tied to existing funds, which were secured via the sale of the land
to the Oshkosh Corporation. Phase One is thus more immediate and will be
implemented following the adoption of the Master Plan, though the full cost of
the Phase One implementation, as indicated in this section, is contingent on
fundraising efforts for select improvements (such as the splash play area).
The latter phases (phases two through five) are intended to create sets of
priorities and sequence those priorities such that critical infrastructure –
parking, trailheads, and connecting pathways – is established and ready
to support future park improvements such as multipurpose lawns, picnic
structures, and pier. The priorities represented by these phases may be
built out as identified herein, or each phase may be built out as funding or
staff resources are available. The budgeting exercise is intended to guide
a logical implementation sequence, prioritize the community’s values
(as ascertained during the planning process), and define the baseline
targets for public investment required to execute the Master Plan.
PHASING THE MASTER PLAN
LAKESHORE PARK MASTER PLAN | OSHKOSH, WISCONSIN32
PHASE ONE
The catalytic Phase One project includes the Punhoqua Terminus improvements at the East Park.
These improvements are intended to create a flexible, year-round community space, leverage
existing infrastructure, and complement the adjacent park program. Phase One includes:
●a four-season multipurpose building and associated terraces and outdoor spaces
●a public plaza
●a splash pad
●+/- 80-car parking lot and drop-off, and a cul-de-sac with on-street parking at the north end of Punhoqua Street
●two large multipurpose lawns
●pathways defining and connecting the Phase One improvements to one another and to the Riverwalk
●the articulation and restoration of the ponds north of the four-season building
●a +/- 20-car parking lot at Veterans Trail, at the northwest corner of Rainbow Memorial Park
Figure 5.1. Phase one extents.
33
PHASE TWO
Phase Two is understood as the West Park complement to Phase One: an initial investment
meant to establish access for and create activity within the west half of Lakeshore Park.
These improvements provide vehicle access to the West Park and establish a trailhead/
orientation point for the Lakeshore Park connections to the Riverwalk and the Tribal
Heritage Crossing of the Wiouwash Trail. Phase two also includes the West Park’s Great
Lawn, a flexible space for picnicking, lounging, sport, and community activities.
Importantly, phase two also creates a setting for the recognition of the parkland’s rich cultural
history. Whereas the specific physical definition of this site and the interpretive message it will carry
will require its own process of community engagement and outreach, research, and design, phase two
includes a home for this piece of the Master Plan as the community clearly articulated its importance..
Figure 5.2. Phase two extents..
LAKESHORE PARK MASTER PLAN | OSHKOSH, WISCONSIN34
PHASE THREE
The third phase of the Master Plan implementation is focused on water. The existing golf course
ponds are revamped, their margins regraded and reconfigured to increase the amount of pond-
wetland ecotone, visually link the water bodies, and create wetland restoration areas which link the
ponds thematically without altering their underground infrastructure or decreasing their capacity.
Phase three includes the removal of the concrete rubble rip rap along the Lake Butte des
Morts shoreline. In its place, a combination of stone revetment, stepped stone revetment, and
vegetation-stabilized shoreline provides necessary protection by reducing the amount of hardened
edge and introducing water-edge habitat in lieu of broken concrete and feral vegetation.
The final water-centric phase three master plan component is the fishing/personal watercraft
pier. This extension of the phase one overlook may include fishing platforms, seating, side/tie
dockage for canoes, kayaks, and other personal watercraft, and an accessible kayak launch.
Figure 5.3. Phase three extents..
35
PHASE FOUR
Figure 5.4. Phase four extents. .
Phase four includes the build-out of the remainder of the West Park, including the small
multipurpose lawn, earthworks, landscape restoration, the hilltop icon, and the remaining West
Park pathways. Phase four also includes three structures – a restroom building west of the West
Park parking lot and two open-air picnic shelters at the Great Lawn. Phase four leverages the phase
two investment (West Park access) and reinforces the Great Lawn as a place and destination. The
earthworks improve the quality and experience of the West Park core, while prairie, savanna, and oak
woodland habitat restoration transforms the remaining golf course turf into functional habitat.
LAKESHORE PARK MASTER PLAN | OSHKOSH, WISCONSIN36
PHASE FIVE
Figure 5.5. Phase five extents. .
The final phase of the Master Plan implementation completes the East Park. Phase five
includes the remaining East Park pathways and multipurpose lawns, as well as the restoration
of the East Park acreage that wasn’t revamped in phase one. Lakeshore Park’s complement
to Mary Jewell Park is also included in phase five. The last remaining parking area – the lot
off North Eagle Street for approximately 20 cars – is completed in this phase of work, as
is the nature play playground. The grouping of playground, parking, and lawn just north of
Mary Jewell Park and the lift station/restroom building is meant to expand the combined
program offerings of the two parks in the vicinity of an existing amenity building.
37
BUDGET TARGETS
The coarse grain nature of a master plan or concept-level design, and the number of unknowns at this point in the
planning and design process, create challenges for accurately estimating construction costs for improvements
described in Sections Four and Five of this document. Consequently, the Master Plan proposes budget targets
rather than opinions of probable construction cost. These targets are based upon plan-derived quantities
(takeoffs) and associated unit costs but, in some cases, they are also the result of reasonable assumptions, or
placeholder allowances. Where assumptions are made, unknown costs omitted, or allowances used, they are
clearly noted. The numbers that follow exclude design and engineering fees, and costs for mobilization and
site preparation. A 35% design contingency has been included with the phase-by-phase targets that follow.
Moving forward, the phased implementation of the Master Plan should target funding partnerships to ensure public
dollars are fully leveraged and to expedite the implementation process. Numerous programs are available that could
provide funding support for the design and construction of key master plan components such as infrastructure,
water access, shoreline stabilization and restoration, stormwater management, and habitat restoration.
Phase One: Punhoqua Terminus Improvements
Four-season Building: $1,250,000
The phase one four-season building is budgeted at $500/SF. It is projected to contain a large
multipurpose event room for 120 – 150 people, two sets of restrooms (one accessible from the
interior of the building, the other from the exterior), and mechanical/storage space.
Terraces at Four-season Building: $310,000
The terraces at the four-season building are assumed to be concrete pavement with cast-
in-place concrete walls, stairs, and ramps. Associated planting areas are included
in the above cost, and the budget accounts for a high level of finish.
Public Plaza: $250,000
The public plaza is primarily pavement with planting areas and cast-in-
place concrete seatwalls at the perimeter of the space.
LAKESHORE PARK MASTER PLAN | OSHKOSH, WISCONSIN38
Splash Pad: $300,000
Splash pad costs vary greatly contingent on their complexity, whether or not water is recirculated, and
the degree to which lighting, stepped walls, or other site features are integrated into the water play area.
The $300,000 allowance is intended to cover in-grade water jets and associated infrastructure.
East Parking Lot, Drop-off, Punhoqua Cul-de-sac: $217,000
All vehicular pavements area assumed to be asphalt pavement. Curbing is limited to Punhuqua and the drop-off loop.
Multipurpose Lawns: $53,000
Seeded lawn.
Pathways: $210,000
Concrete pavement.
Articulation and Restoration of Ponds: $226,500
The ponds are maintained in place, and the recently upgraded pond pipe network remains. The budget
was generated by projecting a grading work area (30 feet wide) and depth (6 feet deep) along the length
of the pond edges. To account for edges that will remain as-is, the total volume was reduced by 50%.
On-Street Parking at Rainbow Memorial Park: $16,000
Asphalt pavement.
Phase One Budget Target: $2,800,000
Phase One Budget Target + Contingency: $3,800,000
39
Phase Two: West Park Access and Cultural History Recognition Area
West Parking Lot: $65,000
Asphalt pavement, no curbing.
Trailhead: $75,000
An allowance for an information kiosk, benches, and bicycle racks.
Large Multipurpose Lawn: $138,000
Seeded lawn.
Pathways: $465,000
Asphalt pavement.
Cultural History Recognition Area: $150,000
Any means of recognizing the site’s rich cultural history will require an in-depth process of
outreach, engagement, and design. The budgeting exercise contains an allowance for this
important Master Plan component, but the figure offered above should be reassessed when
the scope and scale of the Cultural History Recognition Area project is defined.
Grading Allowance: $100,000
Create a level, functional lawn and prepare the site for parking and pathways.
Assume a balanced site: earthwork cut = earthwork fill.
Phase Two Budget Target: $1,000,000
Phase Two Budget Target + Contingency: $1,300,000
LAKESHORE PARK MASTER PLAN | OSHKOSH, WISCONSIN40
Phase Three: Pond Network Enhancement + Shoreline Restoration
Articulation and Restoration of West Park Ponds: $760,000
Consistent with the phase one pond restoration, the remaining ponds are maintained in-place,
and the recently upgraded pond pipe network remains. The budget was generated by projecting
a grading work area (30 feet wide) and depth (6 feet deep) along the length of the pond edges. To
account for edges that will remain more or less as-is, the total volume was reduced by 50%.
Removal of Rubble Revetment: $628,000
This figure assumes the entire 4,550 linear feet of shoreline is consistently revetted with a
3-foot depth of concrete rubble. The budget figure above accounts for the removal of this
rubble, as well as the additional excavation required for a new revetment profile.
Shoreline Stabilization and Restoration: $1,902,000
Without the benefit of a coastal analysis of the Lakeshore Park shoreline, the Master Plan budget exercise assumes
that 25% of the total 4,550 LF of shoreline will be protected with new stone revetment. The remainder of the shoreline
– which averages 30 feet between the water’s edge and the new Riverwalk – will be stabilized by vegetation and
restored to promote fish and wildlife habitat. $1,650,000 of the total cost of shoreline protection is stone revetment.
Stepped Revetment at Center Reach of Shoreline: $750,000
Approximately 500 LF of stepped stone revetment is proposed at the center of the restored Lake Butte
des Morts shoreline. This revetment is comprised of large rectangular blocks of stone, quarried to roughly
consistent dimensions, that are stacked to form an edge that can be occupied or used for water access.
Fishing/Personal Watercraft Pier: $250,000
Allowance for a permanent structure with accessible fishing platforms, seating, side-tie dockage, and kayak launch.
Phase Three Budget Target: $4,300,000
Phase Three Budget Target + Contingency: $5,800,000
41
Phase Four: West Park Amenities
Restroom Building: $200,000
Small building with a minimum of two unisex restrooms and an extended
roof that creates 400 SF of sheltered/shaded space.
(2) Open-air Picnic Shelters: $350,000
Permanent structures with large roof overhangs that create 1,200 SF of sheltered/shaded
space. Includes partial windbreak walls. Budget target based on $150/SF.
Remaining West Park Pathways: $250,000
Concrete pavement.
Earthworks: $230,000
Primarily imported fill for geometric mounds ranging from ten to thirty feet tall.
Hilltop Community Icon: $100,000
