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 5 of 101 3 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 6 of 101 4 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 7 of 101 5 • 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. Page 8 of 101 6 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.

Box 128 www.tadi-us.com Cedarburg, WI 53012 PROVIDING TRAFFIC ENGINEERING SOLUTIONS 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 50 of 101 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 Page 51 of 101 Yerkes Observatory Future Growth TIA – Williams Bay, WI November 20, 2025 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.

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.

Future Yerkes Observatory Traffic 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.

Weekday PM Peak Saturday PM Peak Page 54 of 101 Yerkes Observatory Future Growth TIA – Williams Bay, WI November 20, 2025 TADI 6 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.  Exhibit 6: Scenario 1 Peak Hour Traffic Volumes  Exhibit 7: Scenario 2 Peak Hour Traffic Volumes  Exhibit 8: Scenario 3 Peak Hour Traffic Volumes  Exhibit 9: Scenario 4 Peak Hour Traffic Volumes 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.

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. Page 88 of 101 Page 1 of 4 DEVELOPMENT AGREEMENT This Agreement dated this _______ day of ________________, 2026, between the Village of Williams Bay, a Municipal Corporation of the State of Wisconsin, hereinafter referred to as "Village", and Yerkes Future Foundation, Inc., a Wisconsin Corporation, hereinafter referred to as "Yerkes". WHEREAS, Yerkes is the owner of the property located at 373 W. Geneva St. in the Village, also known as Tax Parcel Number WA 518500001 (the Property); and WHEREAS, Yerkes seeks to further develop the Property by constructing improvements consisting of a pavilion and playground, the locations and general designs of which are as more specifically described in the document entitled Yerkes Observatory-Play/Space, attached as Exhibit A; and WHEREAS, while desiring to support the ongoing development of the Property, the Village is also cognizant of the impact which the above-described improvements will have on nearby residential properties, based upon the increased traffic flow to be generated by the utilization of the improvements by the public; and WHEREAS, the Village has determined that it is appropriate to require Yerkes to address the inflow and outflow of traffic on the property by providing for means of ingress and egress within the Property itself and to timely eliminate impact of such traffic on nearby neighborhoods by eliminating the utilization of streets servicing nearby residential neighborhoods; and WHEREAS, Yerkes agrees to construct the improvements and address the traffic to and from the Property as herein described in accordance with this Agreement. NOW, THEREFORE, in consideration of the mutual obligations of the parties, the Village and Yerkes agree as follows: Section I. Traffic Access. A. Except as addressed in subsection B., motor vehicle access to the Property shall continue to be permitted on Parkhurst Place for emergency vehicles only via an access control gate, the keys to which shall be provided to first responders serving the Village. B. Motor vehicle traffic shall use Observatory Place for all access to and from the Property. See Section II. C. Provided, that the ability of motor vehicle traffic to utilize Parkhurst Place to exit the Property shall be permitted for a period of not more than 18 months after the effective date of the approval of the conditional use permit and site plan applications of Yerkes for construction of the pavilion and playground, and related area, at which time the Village shall close access to Parkhurst Place from the Property, except for the access control gate for emergency vehicles only. Page 89 of 101 Page 2 of 4 C. Yerkes acknowledges that it shall not be permitted to construct an access point on Constance Boulevard to permit motor vehicle traffic flow from the Property to Constance Boulevard. II. Private Streets. A. In constructing a private driveway to provide access to vehicles exiting the Property of Yerkes to Observatory Place and back to W. Geneva St., the private driveway will be built to any applicable Village specifications, regulations and guidelines for the construction of said driveway. B. Yerkes shall furnish "as-built" plans of the private driveway with the Village Clerk upon completion thereof. C. Yerkes shall be responsible for maintaining all private streets and private driveways on the Property, which shall include a private driveway constructed to provide full access to Observatory Place and back to W. Geneva Street, as depicted on the attached Exhibit B.. D. Yerkes shall not be required to increase the width of the existing private driveways on the Property. Section III. Easement. A. To facilitate pedestrian and bicycle traffic to and from the Property and throughout the adjoining areas, Yerkes agrees to convey to Village an easement 8 feet in width for a pedestrian/bicycle path adjacent to the west boundary of Constance Boulevard, as is illustrated for demonstrative purposes on Exhibit C. The Village shall be responsible for preparing and recording the easement. Further, the Village shall be responsible for construction and maintenance of the pedestrian/bicycle path within the easement. B. Yerkes shall be permitted to locate and mark the trees they wish to protect adjacent to the west right-of-way of Constance Boulevard. The width of the easement may need to be wider than 8 feet in order to save the trees to be protected while still allowing for the pedestrian path. The timing and materials for the path will be determined by the Village at the time of construction of the pedestrian path by the Village. Section IV. Conditional Use/Site Plan. A. This Agreement is conditioned upon the Village approval of the conditional use permit and site plan applications of Yerkes for construction of the pavilion and playground and related area and this Agreement will become null and void should the Village not approve the conditional use permit and site plan applications. Section V. Heirs and Assigns. Page 90 of 101 Page 3 of 4 This Agreement is binding upon the Village and Yerkes, their respective heirs, successors and assigns and all future owners of the Property. Section VI. General Conditions and Regulations. A. All provisions of the Village’s ordinances are incorporated herein by reference, and all such provisions shall bind the parties hereto and be a part of this Agreement as if set forth in full herein. B. Yerkes shall not assign this Agreement without the written consent of the Village. IN WITNESS WHEREOF, the parties have signed this Agreement. YERKES FUTURE FOUNDATION, INC.

Schroeder Village Attorney, Village of Williams Bay Page 92 of 101 VILLAGE OF WILLIAMS BAY Office of Zoning Administrator 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 Page 93 of 101 seeking approval of the Site Plan and Conditional Use Permit for the outdoor pavilion and play space proposed to be constructed. Site Plan Review Procedure: 1. Review by the Zoning Administrator. (a) The Zoning Administrator shall determine whether the site plan application is complete and fulfills the requirements of this chapter. If the application is determined to be incomplete, the Zoning Administrator shall notify the applicant. The application is complete. (b) The Zoning Administrator shall review the application and evaluate the proposal for compliance with the following data sources: i. Official Zoning Map. ii. The Village of Williams Bay Comprehensive Plan. iii. Applicable FEMA and related floodplain maps. iv. Applicable federal and state wetland inventory maps. The application is in compliance and in accordance with the official zoning map, and comprehensive plan. The parcel is not within a floodplain, or wetland area. (c) The Zoning Administrator shall prepare a written report addressing items above and forward said report 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 conflict with the provisions of this chapter or the Comprehensive Plan, the Zoning Administrator shall note this determination in the report. Please refer to this report as such document. 2. Review and recommendation by the Plan Commission. (a) The Plan Commission, in its consideration of the submitted application, shall take into account the basic intent of this chapter to ensure attractive, efficient, and appropriate development of land in the Village, and to ensure that every reasonable step has been taken to avoid depreciating effects on surrounding property and the natural environment. In its review, the Plan Commission may require such additional measures and/or modifications as it deems necessary to accomplish this objective. If such additional measures and/or modifications are required, the Plan Commission may withhold approval of the site plan until revisions depicting such additional measures and/or modifications are submitted to the satisfaction of the Plan Commission, or may approve the application subject to the satisfaction of the Zoning Administrator.

Adequate control of stormwater and erosion is provided and the disruption of existing topography, drainage patterns, and vegetative cover is minimized insofar as is practical. v. Appropriate traffic control and parking are provided. vi. Applicable performance standards, per Article 8, are met. (c) The Plan Commission may make a written report to the Village Board and/or may state in the minutes its findings regarding Subsection E(7)(b) above and its recommendations regarding the application as a whole. Said report and/or minutes may include formal findings of fact developed and approved by the Plan Commission concerning the requirements of this section, and that the public benefits outweigh any and all potential adverse impacts of the proposed site plan. 3. Review and action by the Village Board. (a) The Village Board shall consider the Plan Commission's recommendation regarding the proposed site plan. The Village Board may request additional information and/or reports from the Plan Commission, Zoning Administrator, and/or the applicant. The Board may take final action on the application at the time of its initial meeting, or may continue the proceedings. (b) The Village Board may approve the site plan as originally proposed, may approve the proposed site plan with conditions (per the recommendations of the Zoning Administrator, the Plan Commission, authorized outside experts, or its own members), or may deny approval of the proposed site plan. Conditional Use Review Procedure: 1. Review by the Zoning Administrator. (a) The Zoning Administrator shall determine whether the application is complete and fulfills the requirements of this chapter. If the application is determined to be incomplete, the Zoning Administrator shall notify the applicant. The application is complete. (b) The Zoning Administrator shall review the application and evaluate whether the proposed amendment meets the following criteria: i. Is in harmony with the recommendations of the Comprehensive Plan. 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. 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 95 of 101 “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 96 of 101 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 97 of 101 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 98 of 101 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 99 of 101 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 100 of 101 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 Page 101 of 101
