Statement of proposed use of property, with pertinent facts regarding the size of area involved, extent of development, type of operation, etc.: Project 1a Play/Space Playground The proposed playground is a custom-designed project created by Monstrum (Copenhagen Denmark) and will be one of only 19 Monstrum-designed playgrounds in the United States to date. The nearest playground designed by the firm will open in 2027 at the Obama Center in Chicago. The playground consists of three play areas and a small building embedded in the forest to the SE of Yerkes with a combined total site boundary of 38,300 square feet (0.88 acre). Overall: • The playground meets all ASTM safety standards and be ASTM certified. • The playground significantly exceeds ADA (Americans with Disabilities Act) standards, providing integrated mixed play for children of all ages and abilities. • The playground has been designed for year-round use. • The playground and amenities have been designed for a maximum capacity of 80 children in simultaneous use. • The playground contains illustrations and/or texts sharing basic concepts of astronomy, science and space. • The play areas are installed over a foundation comprised of a mix of compressed gravel, poured concrete and compacted earth. • The play surfaces are covered with a mix of permeable surfacing (details below) and integrate landscaping utilizing native Wisconsin species and reflecting aesthetics derived from the historic Olmsted garden designs for Yerkes. • The three play areas are connected via ADA compliant ramps, stone stairs, scramble stones for children, a child-scaled bridge and a hidden forest path. • The playground drains to two engineered, planted detention ponds to mitigate runoL and help clean stormwater of any surface contaminants through natural filtration. • The design includes low cast-in-place concrete walls with integrated wood benches along with stone block seating and shaded picnic tables. • An irrigation line for manual hose and sprinkler connections will be installed. • A fence with a latched gate will limit small children’s ability to leave the site through the trail leading downhill (southeast) without their parent’s knowledge. • Based on a GPS survey of trees, the project has been designed and the location altered significantly to minimize the number of desirable trees requiring removal or put at risk. The three play areas: The Blair Family Foundation Supernova A 28’ high play structure made of certified sustainable hardwood and stainless steel resting on a permeable poured-in-place rubber surface. The main structure includes a raised “stage, ” climbing elements, transfer platforms, stairs, a bridge, an internal maze and three slides. Also included are
Page 8 of 104

bounce platforms, monkey bars, climbing posts, and a seating area for 32 for visiting class and home-schooling groups. This area is designed primarily for children aged 6-13. The Planetary Zone A series of planetary shapes small children can play on, in and around, situated on a combination of poured-in-place rubber and ADA compliant engineered wood chips. Included are a walk-in, low-fi planetarium showing star patterns from Williams Bay, a sun with interactive elements, two climbing planets, and climbing posts. This area is designed primarily for children aged 3-7. The Nature Zone A forested child-configurable play area consisting of moveable natural elements including stumps, branches, sticks and materials, along with a 6-bay swing-set, situated primarily on ADA compliant engineered wood chips with a poured-in-place rubber pathway to mark the route to the accessible swing(s). This area is designed for all ages. Operations The playground has been designed for a maximum capacity of 80 children and will operate on a set schedule identical to that implemented for the landscape overall (currently expected to be from 8am to dusk (summer) and 9am – 5pm (winter)). If necessitated by demand during peak periods YFF plans to further control access by requiring patrons arriving by car to book one of a limited number of AM or PM daily time slots to utilize the playground. Fees In order to ensure its ongoing financial sustainability as a non-profit YFF anticipates that in the coming years it will implement an admission charge to the park, akin to that seen at most botanic gardens, historic sites, arboretums, or sculpture parks in the United States. YFF has stated previously and remains committed to providing significantly reduced-fee or free access for all Williams Bay residents to the outdoor oferings at Yerkes. How that commitment may be implemented once an admission charge is introduced has yet to be determined. Parking Initially, parking for Play/Space will be provided by the existing 52 stall Yerkes visitor lot, which YFF believes meets the requirements for parking spots stipulated in Village of Williams Bay ordinances §390-0308 A (Indoor Institutional) and §390-0309 B.4 (Recreational Land Uses/Outdoor Active Recreation), based on observed patterns of parking usage and data from the past four years of public visitation: Maximum regular visitation at Yerkes is 40 persons for any single tour, equating to a requirement for 13.33 parking spaces (one car per 3 visitors per village ordinance). While multiple tours occur daily, they are scheduled such that parking demand does not overlap. Additionally, visitor data indicates less than 5% of Yerkes tour visitors bring a child between 3-13, the age range for the playground.
Page 9 of 104

Hence we do not anticipate a significant increase in tour visitors staying parked at Yerkes for longer periods in order to utilize the playground before/after a tour. Peak visitation for onsite parking during special events is currently 70 visitors for public talks or concerts, equating to a requirement for 23.33 parking spaces (one car per 3 visitors per village ordinance). For events with attendance over 70 Yerkes parks visitors oQsite and arranges shuttle service from Williams Bay HS. Yerkes staQ are served by 10 staQ parking spaces elsewhere on the property (staQ lot to east of building, maintenance shed lot). Thus YFF believes that for the purposes of both maximum regular visitation and peak visitation during special events the existing 52 spot parking lot fulfills the number of parking spots required by Village of Williams Bay ordinance(s). Maximum Regular Visitation 40 tour visitors = 13.33 spots 80 playground users = 26.66 spots Total required: 40 spots
Peak Visitation (Special Event) 70 attendees = 23.33 spots 80 playground users = 26.66 spots Total required: 50 spots It should be noted that the use of the existing parking lot is an interim step. The Yerkes Site and Facility Master Plan calls for the addition of an additional 95 parking spots in the coming years, which integrates the future need driven by increased visitation for landscape use and additional programming. Project 1b Pavilion building The proposed structure is a concrete masonry unit (CMU) building on slab of ~535 SF with a patio slab of ~1,100 SF. The building contains two enclosed family restrooms and a nursing room, all of which serve all outdoor visitors to Yerkes—trail walkers, playground users, dog walkers, and casual visitors. • The building and all amenities are ADA compliant. • Building heat will be provided by a radiant heating system embedded in the slab. The building is vented in summer, but does not have AC. • Electric service will be connected underground. • Natural gas will be used for hot water and the radiant heat. • Sewer connection will be made to the existing site sewer lines/lift stations. • The building contains four spaces: o two identical ADA compliant family restrooms with changing tables. o one combined sensory break room/nursing room with seating, a sink, a quiet play table, and windows providing visibility to the playground and to the woods. o a mechanical closet • The exterior patio will provide shade to 6-9 picnic tables.
Page 10 of 104

• All interior and exterior lighting will be dark-sky compliant. • The building exterior includes a water bottle filling station, drinking fountain, pet water station, and a cell phone charging locker system. • The patio will be covered for rain protection, with runoL directed to the detention ponds. Operations The restrooms and sensory/nursing room will only be accessible during regular site hours (currently expected to be from 8am to dusk (summer) and 9am – 5pm (winter)). The restrooms will be locked outside of the posted hours. The sensory/nursing room will remain locked at all times. Visitors wishing to use the space will text a posted SMS short code to receive an automated reply with the current keycode to unlock the door. The code will be changed periodically. As is current YFF practice, the building will be secured and alarmed when not in use. Statement showing compatibility of proposed zoning district and/or proposed use to the Village Comprehensive Plan: YFF believes the proposed projects supports the Village of Williams Bay Comprehensive Plan in a number of ways. The Play/Space and associated buildings will: 1. provide a unique and high-quality playground for local children and a world-class community amenity to Village residents, 2. accent the cultural oferings of the village, 3. bring visitors to the Village who will support local businesses before and after a visit to Yerkes, bringing economic benefit and growth to village businesses, 4. help to ensure Yerkes – which is in and of itself a significant cultural and historic institution—remains financially healthy and sustainable by helping support the implementation of a future admission charge. We believe the playground and associated building projects tangibly support the following specific goals, taken directly from the Comprehensive Plan: Overall Goals • Preserve, enhance, and promote the Village’s unique historic character and cultural oQerings. • OQer park and recreation facilities that are accessible to all Village residents as well as visitors. • Promote appropriate economic development that complements and helps support the Village’s predominately residential character, relates to the Village’s focus on outdoor recreation and education, helps serve the daily needs of residents, and enhances the Village as a desirable place to live and visit. Cultural Resources • Support community events and destination uses to provide year-round cultural attractions. • Partner with community institutions and foundations to market the community including the Yerkes Future Foundation, George Williams College of Aurora University ("George Williams College”), and the Women’s Leadership Center among others.

Economic Development • Develop and implement a downtown revitalization strategy and plan. • Work with local businesses and institutional uses to promote tourism and economic growth. Statement showing compatibility of proposed zoning district and/or proposed use with adjacent properties: YFF does not propose to change the zoning district for the Observatory from the existing P&I. We believe that the playground and associated buildings are compatible with the adjacent residential properties (to the North and Northeast of Yerkes) and the adjacent commercial properties (to the South and Southeast) because the project(s): 1. are located as far from all residential neighbors as possible, 2. provide outdoor restrooms and amenities that will benefit neighborhood residents, dog walkers, and families utilizing the site, 3. provide neighbors (and other Williams Bay residents) with reduced-fee or free access to a historically significant landscape undergoing constant improvement and a new world-class playground, 4. take a considered and careful approach to visitation and parking, 5. will have controlled access as part of a considered master plan for Yerkes’ future, 6. will help drive economic benefit to Village businesses through the visitors they bring to Williams Bay, and assist in growing a healthy mix of downtown businesses our neighbors can access, 7. will help sustain and increase property values in the Village by helping attract new families to Williams Bay, 8. will help ensure that Yerkes remains a viable non-profit organization not at future risk of closure and residential development.

Evaluation Report
Plan Commission Meeting
June 9, 2026
Prepared: June 4, 2026
APPLICANT: Yerkes Future Foundation Inc. (Owner)
TAX KEYS: WA518500001
STREET ADDRESS: 373 W Geneva Street, Williams Bay, WI 53191
The applicant is requesting approval of a Site Plan Review per Section 390-1206, and a
conditional use permit per Section 390-0223 Conditional Use Permit, and Section 390-0223(C)
(14) Large Developments, for the construction of a new playground space; and a pavilion
building that includes a patio area, two family restrooms, and nursing/sensory room. Originally
the proposal also included the relocation of an existing building onto Yerke’s property, however
at this time the applicant has withdrawn this request and will no longer be considered as part of
the submittal. Yerkes plans to request this again in the future as they continue to develop their
Master Plan.
On October 7, 2025, the proposed project was tabled at the Plan Commission meeting and
feedback was given that more information on the overall Master Plan for Yerkes should be
provided in addition to more information on traffic, parking, and how construction traffic be
controlled. It was suggested a traffic study be completed, and that the applicant address where
individuals will park to utilize the newly constructed playground area.
On December 2, 2025, the proposed project was tabled at the Plan Commission meeting once
again, as commissioners felt a traffic study was crucial. The applicant stated that a traffic study
had been ordered, and they would be receiving it back in the near future. Additional feedback
was given regarding the future traffic flow/pattern of the site, and discussion was had about how
the current proposal for the play space, and pavilion was connected to the Future Master Plan for
Yerkes Observatory.
On February 3, 2026, the proposed project was once again tabled at the Plan Commission
meeting, as the Plan Commission requested more information about a final plan for ingress and
egress from the existing site and suggested that Yerke’s Future Foundation work with the Village
of Williams Bay on a Development Agreement.
As of today’s date the Village Board has approved the final format of the Development
Agreement for the Yerkes Observatory, which addresses the construction of a driveway for
egress that reroutes to Observatory Place to occur within 18 months. At this time the applicant is

According to the 2023 Comprehensive Plan, the Village of Williams Bay has
many goals and objectives to partner with Yerkes Observatory, and help their
continued growth. The proposed project is in line with the Village’s cultural
objectives of the Comprehensive Plan which states:
Page 36 of 104
“Support the long-term preservation of the Yerkes Observatory building and
property, and work with the Yerkes Future Foundation to promote this
institution as a national education and outreach center for science education.”
An additional goal within the 2023 Comprehensive plan is to preserve key
campuses such as Yerkes to advance the Village’s image as place for education,
tourism, and outdoor recreation.
Another important objective of the comprehensive plan is to work with local
businesses and institutional uses to promote tourism and economic growth.
Some of the Village’s most important economic assets are its existing local
businesses. It is generally easier to retain established businesses and industries
than to recruit new ones, and most employment growth in any community
occurs through existing business expansion. The Village will continue to
actively facilitate and encourage the appropriate growth of existing Williams
Bay businesses, either at existing or larger sites in the community. In the
context of a broader economic development initiative, described elsewhere in
this chapter, the Village may also work in collaboration with local business
owners to research, identify, and address obstacles to local business
development and to develop future economic development strategies and the
marketing of the Village for new business. Additionally, the Village could
continue to support and pursue partnerships with the community’s unique
institutions including the Yerkes Future Foundation. Visitors of this institution
can supplement seasonal population loss by supplying more year-round
customers to support local businesses.
ii. Will not result in a substantial or undue adverse impact on nearby
property, the character of the neighborhood, environmental factors, traffic
factors, parking, public improvements, public property or rights-of-way, or
other matters affecting the public health, safety, or general welfare, either
as they now exist or as they may in the future be developed as a result of
the implementation of the provisions of this chapter, the Comprehensive
Plan, or any other plan, program, map, or ordinance adopted or under
consideration pursuant to official notice by the Village or other
governmental agency having jurisdiction to guide development.
The proposed outdoor play space at Yerkes Observatory will not result in a
substantial or undue adverse impact on nearby properties, the character of the
neighborhood, or matters affecting public health, safety, or general welfare.
The project is located within an established institutional campus that has
historically accommodated public visitation, educational programming, and
outdoor activities. The scale, design, and placement of the play structure are
consistent with the existing use and character of the Yerkes property and the
surrounding area.
Neighborhood character will be preserved, as the play space is designed as a
low-profile, open-air amenity integrated into the landscaped grounds and set
back from adjacent residential properties. The use is primarily daytime and
Page 37 of 104
family-oriented, minimizing potential noise or disturbance. Existing tree cover,
open space, and site design elements further buffer nearby properties and
maintain the visual and environmental character of the area.
Environmental impacts are expected to be minimal. The project does not involve
significant grading or impervious surface expansion beyond what is typical for
a play area, and it has been planned to respect existing natural features and
drainage patterns. No adverse effects on environmentally sensitive areas or
public lands are anticipated.
Traffic and parking impacts are also expected to be minor, as indicated by the
revised traffic study focusing on the play space enclosed in your packet. The
play space will function as an accessory amenity to the observatory rather than
a standalone attraction, with visitation largely overlapping existing peak use
periods. Existing on-site parking and access points are sufficient to
accommodate anticipated use without negatively impacting public rights-of-way
or requiring additional public improvements.
The proposed use aligns with the Village’s Comprehensive Plan and applicable
zoning objectives by supporting educational, recreational, and cultural
opportunities while maintaining compatibility with surrounding land uses. With
appropriate operational oversight and any conditions imposed through the CUP
process, the project will not create adverse impacts now or in the future as the
area continues to develop in accordance with adopted plans and ordinances.
iii. Maintains the desired consistency of land uses, land use intensities, and
land use impacts as related to the environs of the subject property.
The proposed project is consistent and in line with the P&I zoning designation
and all its requirements.
iv. The conditional use is located in an area that will be adequately served
by, and will not impose an undue burden on, any of the improvements,
facilities, utilities, or services provided by public agencies serving the
subject property.
The proposed conditional use is located in an area, and on a parcel that is
already developed and adequately served by public facilities and utilities. The
proposed development will not negatively impact any services or public
facilities.
v. The potential public benefits outweigh any and all potential adverse
impacts of the proposed conditional use, after taking into consideration the
applicant's proposal and any requirements recommended by the applicant
to ameliorate such impacts.
The proposed outdoor play space at Yerkes Observatory provides substantial
public benefits that outweigh any potential adverse impacts. The project
expands educational and recreational opportunities for residents and visitors by
Page 38 of 104
offering an inclusive, accessible, astronomy-themed play environment that
supports learning, family engagement, and healthy outdoor activity. It
complements Yerkes Observatory’s established mission of science education
and public outreach while enhancing the site as a community asset.
Potential impacts, such as increased visitation, noise, or traffic are limited in
scope and duration and are consistent with existing public use of the
observatory grounds. The applicant has incorporated thoughtful site planning,
appropriate location and scale, and operational considerations to minimize
impacts on neighboring properties and preserve the historic and natural
character of the site. Any additional conditions imposed through the CUP
process can further ensure compatibility and mitigation as needed.
When weighed against the clear educational, recreational, and community
benefits, the proposed conditional use represents a positive enhancement to the
Village of Williams Bay and the broader region. Accordingly, the public
benefits of the project outweigh any potential adverse impacts.
2. The Zoning Administrator shall prepare a written report addressing items above, to be
forwarded to the Plan Commission for the Commission's review and use in making its
recommendation to the Village Board. If the Zoning Administrator determines that the
proposal may be in conflict with the provisions of the Comprehensive Plan, the Zoning
Administrator shall note this determination in the report.
Please refer to this report as such document.
The property located at 373 W Geneva Street is currently zoned P&I, Public and
Institutional District. There are currently existing buildings on site along with parking
areas for the facilities. As the property continues to be developed, each project shall meet
the following criteria:
Page 39 of 104
After a review of the submitted application and materials the proposed project appears
to be in compliance with all of the following requirements of the P& I Zoning District.
Per Section 390-0309 pertaining to parking requirements the minimum required off-street
parking is as follows: One space per four expected patrons at maximum capacity for any
use requiring over five spaces.
It appears that there are currently approximately 46 parking spaces located on site,
which would accommodate up to 184 patrons.
The P&I Zoning District requires a Conditional Use Permit for all Large Developments
and Group Developments. Per Section 390-0821 a Large Development is defined as Any
institutional, business, or mixed residential and nonresidential development containing
any single structure or combination of structures on one or more contiguous lots or
building sites devoted to land uses on which the total combined gross floor area of all
development exceeds 10,000 square feet. The calculation of gross floor area shall include
indoor and outdoor storage and display areas. The proposed development is required to
adhere to all requirements set forth in Section 390-0821 including building style,
Page 40 of 104
architectural design, building color, traffic, parking, pedestrian access, landscaping, and
lighting.
The proposed outdoor play space at Yerkes Observatory complies with the requirements
of the Public & Institutional (P&I) Zoning District and Section 390-0821 of the Village
Code. The project appropriately seeks a Conditional Use Permit (CUP) as required for
Large and Group Developments within the P&I District.
While the proposed play space consists primarily of outdoor recreational features
rather than enclosed buildings, it is part of an institutional campus where the total
combined gross floor area of existing and proposed development exceeds 10,000 square
feet, thereby meeting the definition of a Large Development under Section 390-0821.
Accordingly, the applicant has submitted the project for CUP review and has designed
the improvements to meet all applicable Large Development standards.
Building Style and Architectural Design:
The play structure and associated site elements are intentionally designed to be open-
air, minimizing visual mass and avoiding conflict with the historic architecture of the
Yerkes Observatory. Materials, forms, and layout are compatible with the existing
institutional character of the campus and are subordinate to the landmark observatory
buildings, and the theme of the play space matches the characteristics and theme of an
observatory but is designed in a way that will be inviting to children.
Traffic and Parking:
The play space functions as an accessory use to existing observatory operations rather
than as a standalone destination. Anticipated visitation largely overlaps with current
public use patterns, and existing on-site parking and access points are adequate to
accommodate projected demand without creating adverse impacts to surrounding
roadways or public rights-of-way, which was also indicated in the enclosed traffic study
completed for this project. For now, Parkhurst Place will continue to be a suitable
option for exiting the site. The applicant is not seeking to change the existing
ingress/egress of the site as a part of this application or proposed development. The
applicant has however indicated that in the future, as a part of their Master Plan, and
as the development continues to grow and expand they understand the need to re-route
traffic and find an alternative exit from the site, other than Parkhurst Place. The
applicant has prepared 3 different options for the Plan Commission to review and
consider. The Plan Commission is not voting on this item as part of this submittal;
however, the applicant has included this information to provide future options for the
site. The options include installation of a new exit off Constance Boulevard,
installation of a new exit off West Geneva Street, and the third option being to continue
using Parkhurst Place.
As a part of this submittal the applicant has indicated that temporary construction
traffic will not be using Parkhurst Place and instead will use the one-way entrance on
West Geneva Street to enter and exit the site during construction. The applicant would
not like to add a permanent two-way entrance and exit to the site off West Geneva
Page 41 of 104
Street, as it compromises the historical Olmstead design. Enclosed in your packet you
will find a letter from the Olmstead Network.
Pedestrian Access:
Safe and convenient pedestrian circulation is provided through existing and planned
walkways that connect the play space to parking areas, observatory buildings, and
other site amenities. The design prioritizes accessibility and complies with applicable
ADA standards. The Village Engineer is seeking an easement on Constance Boulevard
for a future walking path to be established.
Landscaping:
The project preserves existing landscaping and incorporates additional plantings where
appropriate to soften visual impacts, provide buffering, and maintain the park-like
character of the site. Landscaping is designed to complement natural features and
enhance the visitor experience.
Lighting:
Any proposed lighting will be limited, low-level, and shielded to ensure safety while
minimizing light spillover to neighboring properties. Lighting design will be consistent
with the observatory’s historic and scientific mission, including sensitivity to dark-sky
considerations.
By seeking a Conditional Use Permit and designing the project in accordance with the
standards set forth in Section 390-0821, the proposed development meets the intent and
requirements of the P&I Zoning District. The project integrates educational and
recreational improvements in a manner that is compatible with the existing campus,
surrounding neighborhood, and the Village’s adopted planning policies.
Based on the foregoing findings, the proposed outdoor play space at Yerkes
Observatory satisfies the applicable standards for a Conditional Use Permit within the
P&I Zoning District and meets the requirements of Section 390-0821 of the Village
Code.
The Conditional Use Permit may be approved, subject to any conditions deemed
appropriate by the Village to ensure ongoing compliance with applicable ordinances
and the protection of public health, safety, and welfare. If approved the following
conditions shall be included:
1. The temporary gravel parking and staging area shall be removed 30 days after
construction is completed.
2. All requirements of the approved Development Agreement be adhered to.
Respectfully submitted,
Allison Schwark
Zoning Administrator

TIA TECHNICAL MEMORANDUM
DATE: November 20, 2025
BY: Tammi Czewski, P.E., PTOE
Traffic Analysis & Design, Inc.
SUBJECT: Yerkes Observatory Future Growth Traffic Impact Analysis
Williams Bay, WI
INTRODUCTION
Yerkes Observatory is planning for future visitor growth, site amenities, and a new exit route that
will impact traffic volumes and operations at intersections to Geneva Street (STH 67) in
Williams Bay, Wisconsin. This memo was prepared as a traffic impact analysis (TIA) report to
evaluate future peak hour traffic operations for different scenarios that include background/off-
site development traffic growth from “The Preserve” development, Yerkes Observatory visitor
traffic growth, and site exit alternatives. The location of the site and off-site developments, as
well as the intersections evaluated in this study are on Exhibit 1.
SITE CIRCULATION & DEVELOPMENT PLAN
Existing Plan
Exhibit 2 shows the existing Yerkes Observatory site and traffic circulation routes for vehicles
entering and exiting at Geneva Street. All site traffic enters from Observatory Place and exits to
Parkhurst Place.
The existing facility has 22,000 annual visitors, with 10,000 annual visitors in the “summer”
(May through September) and 12,000 annual visitors in the “winter” (October through April).
During the summer, 95% of visitors arrive by car and 5% walk or park off-site. During the
winter, 20% of visitors arrive by car and 80% park off-site. Winter visitors typically come for a
single event and are bussed in from off-site areas.
Future Plan
The proposed changes to the site and traffic circulation routes is on Exhibit 3. Site changes
impacting traffic volumes and operations include the addition of a playground and family
pavilion, a visitor center, a 150-space parking lot (for more on-site parking availability), and a
new connection to Constance Boulevard, which will be used for all site exits to Geneva Street.
The existing connection to Parkhurst Place will be removed with this new plan.
Page 83 of 104
Yerkes Observatory Future Growth TIA – Williams Bay, WI November 20, 2025
TADI 2
With these site enhancements along with increased popularity of the Yerkes Observatory, 56,000
annual visitors are estimated, with 38,000 annual visitors in the summer and 18,000 annual
visitors in the winter. With the increase in site parking, 95% of the summer visitors arrive by
car, and 80% of the winter visitors arrive by car.
EXISTING TRAFFIC VOLUMES
Data Collection & Study Area
Turning movement traffic counts were collected at study intersections in September 2025 and
November 2025. Traffic counts were collected from 3:00-6:00 on the weekday and from 3:00-
7:00 p.m. on a Saturday and are included in Appendix A. The study intersections are:
Geneva Street & Observatory Place
Geneva Street & Parkhurst Place
Geneva Street & Constance Boulevard
Observatory Place, Parkhurst Place, and Constance Boulevard are two-lane local roadways with
stop sign control at the intersections with Geneva Street. Observatory Place and Parkhurst Place
are no outlet roadways that provide access to the Yerkes Observatory and about 10 single-family
residences each. Constance Boulevard extends from Geneva Street and around the Yerkes
Observatory property to the form er George Williams College of Aurora campus, which also has
other connections to North Lake Shore Drive west of the site. The campus is being planned for
redevelopment with a hotel, re staurant, amphitheater, and supporti ng services (spa, racquet ball
courts, pool, etc.). The Preserve at Williams Bay Abbreviated TIA dated February 13, 2025 (herein
referred to as The Preserve TIA) was prepared to identify traffic volumes, operations, and impacts
to intersections along Geneva Street.
Geneva Street (STH 67) is a principal arterial with a 30-mph posted speed limit and a two-lane
undivided cross-section. The roadway has 10-foot-w ide bike lanes in both directions, which are
dashed out at the study intersecti ons. Although not full right-turn lanes, the pavement markings
allow for legal right-turn movements to occur from these lanes. Sidewalks exist intermittently on
both sides of the roadway through the study inte rsections. The Wiscons in Department of
Transportation (WisDOT) reports a 2022 annual av erage daily traffic (AADT) volume of 5,000
vehicles per day (vpd) west of Lake Shore Drive to the west and 6,800 vpd east of Dartmouth Road
to the east.
Exhibit 4 shows the geometrics, traffic control, and intersection spacing along Geneva Street.
Existing Traffic Volumes
The traffic count data was compiled for the peak traffic hours through all study intersections,
which was determined to occur from 3:00-4:00 p.m. on weekdays and from 3:15-4:15 p.m. on
Saturdays. Traffic volumes at the Geneva Street intersections with Observatory Place and
Parkhurst Place were counted in November 2025, which represents the “winter” season volumes
evaluated in this study. These intersections were used to balance traffic through the Geneva
Street/Constance Boulevard Place intersection which was counted in September 2025 for The
Preserve TIA to generate “winter” traffic volumes in the study area.
“Summer” traffic volumes were generated by applying WisDOT 2024 Seasonal Adjustment
Factors (Appendix A) for Seasonal Factor Group 6 (Tourist/Recreational Other), which is how
WisDOT classifies Geneva Street through Williams Bay. The seasonal adjustment factors

TADI 3
between November and July were applied to through volumes on Geneva Street to develop peak
summer season volumes. Both the unadjusted “winter” and adjusted “summer” existing peak
hour traffic volumes evaluated at the study intersections are on Exhibit 5.
Existing Yerkes Observatory Traffic
Both Yerkes Observatory traffic and traffic from the single-family homes along Observatory
Place and Parkhurst Place are included in the intersection traffic counts with Geneva Street. Due
to the one-way traffic patterns for the Yerkes Observatory, outbound traffic turning from
Observatory Place and inbound traffic turning onto Parkhurst Place were identified as single-
family home traffic. Using weekday and Saturday peak hour in/out percentage data from the
Institute of Transportation Engineer’s (ITE) Trip Generation Manual, 11th Edition for land use
#210 (single-family detached housing), opposing traffic for the single-family homes were
calculated. Separating the single-family home traffic, it was determined that the Yerkes
Observatory generated about 20 trips (7 in/13 out) during the weekday PM peak hour and 36
trips (18 in/18 out) during the Saturday PM peak hour.
Yerkes Observatory provided daily traffic volumes for the same days traffic counts were
collected at the Geneva Street intersections with Observatory Place and Parkhurst Place. Using
this data, it was determined that 8% of the weekday daily Yerkes Observatory trips occurred in
the weekday PM peak hour, and 15% of the Saturday daily Yerkes Observatory trips occurred in
the Saturday PM peak hours. These rates were used to determine future peak hour trips from
future daily attendance estimates. The existing Yerkes Observatory trip generation and traffic
assumptions are shown in Table 1.

-Inbound residential tra ffic was estimated by applying ITE #210 in/out distributions to the outbound residential tra ffic.
-Each vehicle generates one inbound tri p and one outbound trip per day, but those trips may not occur in the same hour.
-Yerkes Observatory inbound traffic was determined by subtracting estimated inbound residential tra ffic from traffic counts.

FUTURE TRAFFIC VOLUMES
The Yerkes Observatory Director provided winter and summer weekday and Saturday daily
visitor estimates for two volume scenarios: existing traffic plus a playground addition, and future
visitor growth of the whole site.
Future Yerkes Observatory Traffic – Playground Addition
During the winter, the playground is expected to be visited by an average of 30 children on
weekdays and 60 children on Saturdays (100% will arrive by car). During the summer, the
playground is expected to be visited by 140 children on weekdays and 220 children on Saturdays
(80% will arrive by car). For the purposes of this study, playground visitors are estimated in
addition to the existing traffic traveling to/from the Yerkes Observatory. Using the same peak-
to-daily ratios as existing traffic at the Yerkes Observatory, the playground is estimated to
generate three (3) additional weekday PM and four (4) additional Saturday PM trips during the
winter, and 10 additional weekday PM and 19 additional Saturday PM trips during the summer.
Future Yerkes Observatory Traffic – Playground Plus Visitor Growth
In addition to playground visitors, tour traffic growth estimates were used to generate future peak
hour visitor traffic to the Yerkes Observatory. The Yerkes Observatory offers set tours and
program times that overlap during the peak hours (exiting traffic from one tour will occur in the
same hour that entering traffic arrives for the next tour). Although more tours are expected to
occur on Saturdays, only one tour occurs at one time. Therefore, tour visitor numbers and traffic
generated from the tours are the same for both the weekday PM and Saturday PM peak hours.
An average of 55 visitors per day and 25 visitors per tour is estimated during the winter (80%
arrive by car) and an average of 207 visitors per day and 40 visitors per tour is estimated during
the summer (95% arrive by car). For the purposes of this study, future build traffic estimates for
the tours are estimated to replace the existing traffic at the Yerkes Observatory. The net new
Yerkes Observatory traffic (tours plus playground visitors) is therefore calculated as 34
additional weekday PM and 14 Saturday midday trips during the winter, and 77 additional
weekday PM and 65 additional Saturday midday trips during the summer. The future Yerkes
Observatory trip generation and traffic assumptions are shown in Table 2 (next page).
Traffic Distribution
Existing traffic entering and exiting at the Geneva Street intersections with Observatory Place
and Parkhurst Place follow this distribution pattern:
42% to/from the west on Geneva Street
58% to/from the east on Geneva Street
All future trips for the Yerkes Observatory were assigned to the study intersections using this trip
distribution pattern.

Traffic Volume & Access Scenarios
This study evaluates the study intersections with four traffic volume and access scenarios:
Scenario 1: Existing Yerkes Observatory traffic plus additional visitor traffic to the new
playground area. Yerkes Observatory traffic enters from Observatory Place and exits to
Parkhurst Place.
Scenario 2: Existing Yerkes Observatory traffic plus additional visitor traffic to the new
playground area. Yerkes Observatory traffic enters from Observatory Place and exits to
Constance Boulevard.
Scenario 3: Existing Yerkes Observatory traffic plus new trips from “The Preserve”
development (includes Saturday amphitheater event). Yerkes Observatory traffic enters
from Observatory Place and exits to Parkhurst Place.
Scenario 4: Future Yerkes Observatory traffic (includes tour and programming growth
and additional playground visitors) plus new trips from “The Preserve” development
(includes Saturday amphitheater event). Yerkes Observatory traffic enters from
Observatory Place and exits to Constance Boulevard.

Traffic volumes for each of these scenarios were calculated for the weekday PM and Saturday
PM peak hours during both the winter and summer seasons. The volume exhibits show the new
development trip assignments (Yerkes Observatory in orange and “The Preserve” in light blue)
as well as the existing Yerkes Observatory traffic reroutes from exiting at Parkhurst Place to
exiting at Constance Boulevard (in green). The total traffic volumes that combine these
development trips with the existing background traffic volumes are shown in black. “The
Preserve” traffic assignment was obtained from the February 2025 TIA.

PEAK HOUR TRAFFIC OPERATIONS
The study intersections were analyzed using the Synchro 12 traffic analysis model (outputs based
on the Highway Capacity Manual, 7th Edition) and the peak hour turning movement volumes
estimated for each intersection. Intersection operation is defined by “level of service.” Level of
Service (LOS) is a quantitative measure that refers to the overall quality of flow at an
intersection ranging from very good, represented by LOS ‘A’, to very poor, represented by LOS
‘F’. For the purposes of this study, LOS D or better was used to define acceptable peak hour
operating conditions. The LOS definitions for signalized and unsignalized intersections are in
Appendix B.
Exhibits 10-12 include tables that show the study intersection lane geometrics, 95th percentile
queues (in feet), delays (in seconds per vehicle), and corresponding LOS. The tables are
separated by peak hour and season (winter and summer). The LOS tables and appendix location
with the Synchro analysis files for each scenario are listed below.
Exhibit 10 (Appendix B): Scenario 1 Peak Hour Traffic Operations (LOS Table)
Exhibit 11 (Appendix C): Scenario 2 Peak Hour Traffic Operations (LOS Table)
Exhibit 12 (Appendix D): Scenario 3 Peak Hour Traffic Operations (LOS Table)
Exhibit 13 (Appendix E): Scenario 4 Peak Hour Traffic Operations (LOS Table)
With the existing Yerkes Observatory visitor volume plus additional traffic from the playground
addition, all turning movements at the study intersections operate at LOS B or better during the
winter and summer weekday PM and Saturday PM peak hours (Scenarios 1 and 2). With the
existing Yerkes Observatory visitor volumes plus additional traffic from “The Preserve”
development, delays increase to LOS C or better (Scenario 3). With future visitor projections
(including the playground addition) added to Scenario 3 traffic volumes, delays for all
intersections remain at LOS C or better (Scenario 4).
CONCLUSIONS
The analysis shows that there are relatively low increases in delays and queues with future
buildout of the Yerkes Observatory site. LOS C or better conditions are expected all study
intersections, even with traffic exiting to Constance Boulevard instead of Parkhurst Lane, and
even during an amphitheater event on Saturday within “The Prairie” development.

Engineer Review Comments – Second TIA
Yerkes Observatory
January 17, 2026
As requested, we reviewed a second traffic impact analysis (New TIA) study for Yerkes Observatory
dated December 27, 2025. In general, we see no issues if the Village approval requires Yerkes to
follow this TIA, which means they only enter and depart on Geneva Street. As a reminder, we need
an access easement (width varies to save existing trees) adjacent to Constance Boulevard for a future
pedestrian path.
We have the following specific comments on the New TIA:
This traffic impact analysis no longer proposes an entrance to Constance Boulevard nor
references any future development of the site beyond the proposed playground.
Although not acknowledged in the report, Yerkes plans to continue to expand development on
the site that was presented in the TIA (Original TIA) from December 3, 2025; these plans should
be removed from the New TIA if these plans are expected to occur more than 10 years after the
initial playground construction. The Village should confirm with the owner no future
development is expected to occur within 10 years of playground construction if this new TIA is
be considered valid.
The New TIA appears to use the same traffic data and projections for playground as the Original
TIA. We do not take exception to the traffic data or analysis completed; however, we do have the
following comments/concerns for the Village to consider.
o On a peak hour basis, the playground will add minimal traffic impacts to the existing
intersections at W. Geneva Street (STH 67); however, when your look at the daily impact, i.e.
average daily traffic throughout the day, daily traffic volume (entering & exiting) is expected
to more than double during the summer with the addition of the playground. As noted in my
previous review, this suggests increased traffic throughout the day instead of the regimented
peak periods that is currently experienced from tour times and special events. This means
more traffic will be observed at Parkhurst during times of the day not previously
experienced. It should be noted; however, the impact should still be low, because the increase
in Saturday traffic translates to, on average, 1 additional car every 4 minutes.
o The discharge to Parkhurst Place is currently gated and only open for tour traffic and special
events. Is the gate intended to be opened all day during operating hours of the playground
or will there be times traffic will have to exit using Observatory Place? If the latter, we
recommend keeping the daily playground traffic using Observatory Place for both ingress and
egress and only opening the gate to Parkhurst for special events and peak tour times. This
would then result in little change for the residents in Parkhurst Place.
To summarize, if no additional development is expected within 10 years of the playground
construction, then the new TIA is valid; we agree that peak hour impacts from the playground will be
minimal, but more traffic will be observed on Parkhurst Place throughout the day; the impacts to
Parkhurst Place assume the egress gate is open during the hours of operation of the playground, but
we again recommend limiting further impacts to Parkhurst Place by directing daily playground traffic
to enter and exit using Observatory Place.
