1.1 Purpose
1.1 PURPOSE
The Department of Parks, Recreation and Neighborhood Services (PRNS) has prepared this Master Plan Update to prioritize restoration of park features and guide the design and construction of new amenities at Overfelt Gardens Park. The goal is to preserve, restore and enhance this regional park. New amenities are anticipated to encourage and support greater usage of the park by offering refreshed park features and unique attractions and programming to both local users and regional visitors.
This Master Plan Update provides a framework for revitalizing Overfelt Gardens Park, a special space with a pleasing, timeless design that can be retained and celebrated without significant design intervention. This document is informed by community input and ActivateSJ goals.
Section 2 describes the park’s location in East San Jose and surrounding land uses, which include residential, education and medical. The park’s origins and several previous Master Plans are outlined, as well as nearby park offerings. A detailed Site Analysis exploring opportunities and constraints for the park is provided.
Section 3 details the Planning Process, which was guided by ActivateSJ and General Plan Goals and led to a vision for the Master Plan Update to ensure the park’s future as:
• An outstanding, passive, garden-focused park;
• A cultural destination;
• An icon for San Jose’s identity; and
• A place to visit over and over again.
The outreach program included a variety of City and outside agency stakeholders, as well as the community at large. Three community meetings and two surveys were conducted to inform and solicit feedback from the public. This section also includes a discussion of the technical study of the existing ponds that was completed as part of this process.
Section 4 describes the overall concept for the Master Plan, which includes the designation of 5 distinct districts within the park: Farmhouse District, Botanical Garden District, Chinese Cultural Gardens District, Nature District, and Civic District. Recommended improvements are described, along with the ActivateSJ principles they support. A discussion of recommended programming is also provided.

2.2 NEIGHBORHOOD
Overfelt Gardens Park is situated centrally between highways I-680 and I-101 in the “McKee/Jackson” neighborhood of Council District 5.
Rectangular in form, the park is bordered by Independence High School and Educational Park Branch Library to the north, Santa Clara County Health Department to the east, McKee Road to the south, and Educational Park Drive to the west. The park shares a parking lot with the Library. The Regional Medical Center of San Jose is located across McKee Road at the corner of Jackson Avenue. The remainder of the area is largely residential.
McKee Road functions as a major thoroughfare along which small commercial buildings and apartments are situated. This is contrasted by Educational Park Drive which serves as a residential street lined with singlefamily homes. The park’s primary frontage along McKee Road is largely shielded from view by shrubs and trees. Modest signage announces the park, but there is little indication to pedestrians and drivers of the park’s size, features and attractions.
Based on the 2020 Census, the residential community in the immediate area of the park closely mirror both the age and ethnic distributions of the City as a whole.

2.3 HISTORY AND PREVIOUS PLANS
William and Mary Overfelt farmed grain and dairy on approximately 160 acres in the late 1800’s as early San Jose pioneers. In 1959, their daughter, Mildred Overfelt, granted 33 acres of that land to the City of San Jose for a park to be developed in honor of her parents. Mildred specified that the goal of the future park would be “to provide a place of rest, relaxation, aesthetic, and other enjoyment for the people of San Jose”. Included in the deed is the restriction that “the City shall have no right to construct or establish, nor permit the construction or establishment of any football, baseball, basketball, soccer, or tennis fields or courts”, thus formalizing the passive intent for the park.
In the early 1960s, the City developed plans for annual-perennial, palm desert, and California native plant gardens within the southern eight acres of the property. The park and its collections of gardens opened to the public in 1966. One of the early and unique features of Overfelt Gardens was the Fragrance Garden for the Blind. The Fragrance Garden opened in 1971 and featured a variety of plants picked for their capacity to engage the sight-impaired through fragrance and texture, with braille coded signage for plant identification.
Chinese culture became an integral part of the park’s identity in the early 1970s. The Chinese Cultural Garden was made possible through a partnership between the park planners, San Jose residents and friends of Mildred Overfelt, Frank and Pauline Lowe, and Dr. Chen Li-Fu of Taiwan.
Chinese-style art and structures were installed with a vision to broaden the understanding between Eastern and Western societies in a tranquil setting.
The Chinese Cultural Garden spans five acres in the park.
San Jose City Council has approved several master plans over the past 50 years, each with a specific objectives and goals. A 1972 Master Plan led to further park development in 1974, with construction of three ponds and a reflecting pool. These bodies of water framed by rolling topography provide the structure for the park’s current layout.
The 1974-75 Master Plan sought to provide a framework for the park’s varied amenities:
• Offer a place for educational and scientific activities; • Label plants for awareness, critical examination and scientific study; • Provide gardens as a cultural center with facilities such as an amphitheater, demonstration gardens, conservatory, library and the Chinese Cultural Garden area; and
• Operate and maintain with an assigned supervisor, staff and labor force.

A number of improvement projects followed this Master Plan, including two additions to the Chinese Cultural Gardens; the Chiang Kai-Shek Pavillion and the Sun Yat Sen Memorial in 1983.
In 1989, a Master Plan was prepared for the site that emphasized the park as a botanical garden. The plan’s goals included, among others, the following:
• Re-establish and enhance the botanical nature of Overfelt Gardens;
• Enhance, enrich and provide for adequate maintenance and programs within the cultural elements and garden areas of the park;
• Protect, preserve and enhance the natural areas and wildlife species; and
• Promote public safety within the park.
The plan recommended the addition of multiple buildings that were never added to the park. These include a Botanical Center, a Conservatory, an Office/Service Building, and a Storage Building at an estimated total cost of $2,325,000 in 1989 dollars.
The Overfelt family home, constructed in 1876, is located on the park site. In 1985 it was designated as Historic Landmark No. 30 by San Jose City Council. In 2006, a restoration of the structure was completed, which included space for programmed uses including a visitor center, offices, meeting and classrooms, kitchen and restrooms.
In recent years, the City prepared a Conditions Assessment of the monuments in the Chinese Cultural Gardens. Staff sought to determine actions needed to ensure the sustainable preservation of these important structures. Over the same timeframe, it became clear that the existing water supply to the ponds was unreliable and that the ponds were declining as a result. It was decided to prepare an Master Plan Update to reflect the current realities of the park.

2.4 PARK CONTEXT
In the context of the parks and open space in the area, Overfelt Gardens Park is unique in character and what it offers to the community. The park offers cultural elements that provide visitors a space for learning, reflection and a serene, natural environment. The passive nature of
Overfelt Gardens, the historic farmhouse, unique Chinese cultural monuments, ponds, and meandering paths within
abundant mature trees contrast with the active nature
of other parks in the area. Several parks exist within a two-mile radius and provide a range of active recreation opportunities, including soccer fields, basketball courts, exercise equipment, playgrounds and a skate park.
Nearby parks and their amenities are summarized in the
table below.

Description Opportunities & Constraints
Existing Layout & Topography Opportunities & Constraints • Park is comprised of rolling hills (21 acres), three
“percolation” ponds (4 acres), flat and gently
rolling turf (7 acres) with remaining acreage in
parking and meandering pathways.
• The existing layout of ponds, meandering walks,
rolling topography and flat grassy areas within the
park represents a pleasing, timeless design that
can be retained and celebrated without significant
design intervention.
• The ponds set within undulating topography
create visual interest and a sense of discovery.
• These basic elements of the park alone (water
features, gardens, turf areas, trees and understory)
require a considerable amount of ongoing
investment in maintenance to keep the park
welcoming.
• A berm and abundant mature trees in the
southeast corner of the park buffer the park from
the busy street but block views and do not foster
an inviting presence from the street.
• Park edges could be improved to announce the
park’s presence as a public space, make park
more inviting and facilitate pedestrian access from
surrounding uses.
Parking Lot (shared with Library) Opportunities & Constraints • Concrete park name sign is small and outdated
and does not visually convey the grandeur and
character of the park.
• Paid parking could discourage disuse but may
also discourage park users.
• Pavement in poor condition, striping faded. • Library could validate parking for park and library users.
• Does not visually enhance the park. • Refurbishment of parking lot would express a higher quality space in keeping with the special
nature of the park.
• Used by high school students and unhoused,
reducing available spaces for park users
Entries Opportunities & Constraints
Primary Entry (Educational Park Drive)
• Existing primary entry kiosk is unused.
• Steps limit accessibility.
• Lacks cohesive design and does not visually
convey the character of the park.
McKee Road Entry
• Existing entry consists of a modest opening in
the chain link fence.
• Existing entries could be enhanced with
distinctive, unified design elements that convey the
park’s character.
• Additional entries would facilitate pedestrian access to the surrounding community and enhance the
park’s presence in the area, potentially encouraging
greater use.
Independence High School
• Existing entry consists of a modest opening in
the chain link fence.
Service Gate
• A vehicular service gate is accessed from the
County Health Services building. This is for
authorized personnel only.

Overfelt House Opportunities & Constraints
• The Overfelt House was built in 1876 and is a
designated historical landmark by the City of
San Jose.
• The house is in good condition following the
renovation and has good potential to be further
celebrated as a feature of the park.
• The house was restored in 2006 and now
houses offices and supplies for park staff.
• The renovation intended for it to be used as a Park
Visitor Center for the public. This function has not
yet been implemented but could be in the future.
• The house itself is a visual attraction but
currently offers little visitor experience.
• The area around the house could be enhanced
to provide a unique event space creating an
opportunity for the community to enjoy this historic
resource.
• The house is surrounded by unattractive
service yard buildings, service parking,
dumpsters and fenced areas for storage with
unsightly shipping containers, which detract
from the experience of the home for park
users.

FIGURE 2.5.C Existing Site Features
20 Site Context
OVERFELT GARDENS PARK MASTER PLAN UPDATE
Ponds Opportunities & Constraints
• Three ponds with surface areas of 1.1 acres
1.14 acres and 1.9 acres create a central
design element of the park.
• Recycled water was brought to the park in late
2020 providing connections for park irrigation and
the reflecting pool and also provides a possible
new water source for the ponds.
• Ponds have not received a water supply from
Penitencia Creek for several years and Santa
Clara Valley Water District (Water District) has
indicated that no future water supply from
them should be expected.
• Use of recycled water to fill the ponds will likely
trigger Santa Clara Valley Water District
involvement in the design of the features.
• Ponds are in decline and at times emit foul
odors. They do not fill adequately during
rainy seasons and at least one has almost no
ponding during extended dry periods.
Picnic & Restrooms Opportunities & Constraints
• A reservable group picnic shelter is located in
the gardens area of the park. It is aging and
lacking in distinctive character. There is no
barbeque, as barbeques are not permitted at
Overfelt Park.
• A renovation of this area would improve the
aesthetic character and functionality of the space
to create better unity between the elements and
provide more useability for visitors.
• A restroom building is located near the group
picnic area. The restroom building has four
stalls for men and women. The building has a
mural painted on the side. The building is
aging and reflects an outdated design
aesthetic.
• Beautifying the area and allowing additional uses,
such as barbecue installations, would likely attract
reservations and draw revenue.
• There is little design character or aesthetic
unity between these structures.

Chinese Cultural Gardens Opportunities & Constraints
Includes the following monuments:
1. The Sun Yat-sen Memorial Hall (constructed
1983-84)
2. Chiang Kai-shek Pavilion (constructed
1983-84)
3. Plum Pavilion (constructed 1986-87)
4. Friendship Gate
5. Confucius Statue & Reflecting Pool
6. The Sundial
In 2014 and 2017 two reports1 were prepared providing
condition assessments and recommendations for
safeguarding the preservation of some of the
monuments:
• Sun Yat Sen Memorial Hall
• Chiang Kai-shek Pavilion
• Plum Pavilion
• Friendship Gate
• The first four monuments in the list above
were assessed in 2014 and 2017 and were
found to have various deficiencies, including
roof leaks, tile damage, water damage and
cracked mortar.
• Recommended improvements in the reports could
be prioritized and implemented as part of the
Master Plan Update.
• A concrete lined reflecting pool is located
under the Confucius Statue. It is currently
drained and in need of resurfacing, creating
a sense of blight within the park.
• A recycled water connection was brought to the
system serving the reflecting pool. The pool could be
resurfaced and served by this recycled water,
returning to its former beauty.
Landscape/ Botanical Gardens Opportunities & Constraints • Oak trees are the predominant tree but
other native and non-native trees are
present on the site.
• Abundant mature trees provide environmental
benefits and support the park’s status as a natural
place for passive recreation.
• Native and non-native species provide
understory for habitat and park character.
• Two recycled water irrigation connections were
added to the park in 2020, meaning that the
parks irrigation system is not using potable water,
reducing, though not eliminating, the concern about
the landscape’s consumption of water.
• A palm garden with numerous palm species
remains from the original botanical garden.
• A large number of trees need to be monitored and
maintained for tree health and user safety.
• Other former gardens are no longer present
or are in decline.
• Existing and future plantings should be considered
for both drought and recycled water tolerance.
• Signage identifying plant material is
damaged or missing.
• A turf lawn is located in the botanical
gardens area. Its placement, size and
orientation do not convey that it is a central
gathering space for events or an element to
orientate users within the park.

Circulation Opportunities & Constraints
• A range of path types exist within the park.
The paths vary in width, condition and
material.
• A “walking loop” could be identified and marked
with distance markers, adding a simple program
element at relatively low cost.
• The meandering layout of the paths are
pleasing and support the gardenesque
nature of the park.
• Existing circulation should be assessed for ADA
compliance.
• Routes needed for service vehicles should be vehicle
rated, including any bridges
Service & Storage Opportunities & Constraints
• The primary service yard for the park is
located near Overfelt House. The house is
currently being used by staff rather than for
park visitors.
• Service yard and staff space is needed but could be
consolidated and reallocated for efficiency.
• Service yard includes several aging and
mismatched structures, fencing, storage
containers and visible dumpsters, all of
which obscure views of the house.
• Frontage along Educational Park Drive impacts park
aesthetics and park visitor experience as they reach
primary entrance gate/parking lot. Improvements to
this area could consider aesthetics from said street
to improve visitor experience.
• The location directly adjacent to and visible
from Educational Park Drive and near the
park’s primary entry detract from the entry
experience and does not celebrate Overfelt
House to its maximum potential.
• Service vehicles enter the service area off
the parking lot. There is a vehicular
connection to the park from the service
area.
• A vehicular gate for staff only exists off the
parking lot for the County Health Facility to

Fencing Opportunities & Constraints
• The perimeter of the park is fenced and can
be closed at night.
• Harmonizing and enhancing the fence could help
define the park’s edges, and create a more unified
aesthetic and better convey the park’s character.
• Fence design lacks consistency, with the
majority being chain link and not attractive.
• Perimeter planting and berms make
observation of the park from the street
difficult.
• Selective openings and enhancing of views into the
park to attractive park amenities while retaining
sufficient edge planting to maintain the secluded
feel within the park could improve the park’s
presence in the neighborhood, attract users and
support a sense of safety.

OVERFELT GARDENS PARK MASTER PLAN UPDATE
Site Furnishings Opportunities & Constraints
• There is a limited amount of site furniture in
the park, consisting mainly of picnic tables
and benches.
• Harmonization and careful selection of materials
and theming for site furnishings could enhance the
park aesthetic and sense of place.
• Locations do not maximize primary views. • Carefully sited seating nodes could improve enjoyment of the park’s key features.
• Styles vary and do not relate to adjacent
buildings or landscapes.
• Donor benches or other donor recognition
elements, consistent with the PRNS donor policy,
could be implemented for fundraising and to
promote a sense of ownership of the park.
• Condition and manufacturers vary, with
much of the furnishings aging and in
decline.
• Durable, vandal resistant and easily replaceable
furnishings are preferred by City maintenance teams.
• Some benches are designated donor
benches with plaques.
• Replacement of any existing donor benches should
consider whether the donor should/could be
recognized elsewhere.

OVERFELT GARDENS PARK MASTER PLAN UPDATE
Signage Opportunities & Constraints
• The park has limited signage for both
interpretation and wayfinding.
• A new interpretive signage program could be
developed that educates park users about
various topics, ranging from the natural and cultural
history of the site, the Chinese cultural gardens and/
or current ecological elements.
• The signage that exists is inconsistent in style
and content.
• Clear and consistent wayfinding could help users
navigate the space and facilitate enjoyment of key
park features.
• Many signs are old and in disrepair. • The signage program could be “branded” and coordinated with other site elements to provide a
unified look and feel throughout the park.
• Wayfinding to nearby transit and other park
resources is lacking.
• All signage must be durable and vandal resistant
• Translation of signage into languages widely used in
the area should be considered.

3.2.2 Vision
Based on the review of Council-approved planning
documents and consideration of existing site conditions, the guiding vision for the Overfelt Gardens Park Master Plan Update was developed. The Master Plan Update seeks to
provide a framework for the park that ensures its long term future as:
• An outstanding, passive, garden-focused park;
• A cultural destination;
• An icon for San Jose’s identity; and
• A place to visit over and over again.
Achieving this vision is intended to meet the objectives of facilitating event spaces, sustaining historical and cultural attractions, and preserving and expanding unique landscapes in a manner that is fiscally sustainable. The park’s unique assets are appropriate as Overfelt Gardens Park is a regional park within San Jose’s Park System of neighborhood, community, and regional sites.
3.3 STAKEHOLDER OUTREACH
3.3.1 Approach
The outreach strategy involved a multi-pronged approach that sought to solicit input from specific City departments and external agency stakeholders, as well as the community at large. A Technical Advisory Committee made up of key City department representatives was assembled. Other outside agency stakeholders were invited to attend individual focused meetings to share their specific priorities or concerns related to the park. This initial outreach was intended to identify any key issues or constraints that should guide how the project was presented to the wider community for input. Three virtual community workshops were planned, along with online
surveys corresponding to the timing and subject matter of the first two meetings. Given the area’s demographics, outreach materials were translated into Chinese, Vietnamese, and Spanish to encourage participation.
3.3.2 Technical Advisory Committee (TAC) (Identify and issues) The Master Planning team consulted representatives from a number of City departments with potential interest in the design of the park. The TAC included the following:

• Walking path with distance markers.
• Level and maintained area for yoga, pilates, tai chi or meditation (classes 10-50 people). • Outdoor classroom (up to 50 people). In the past, room size has been a limiting factor.
Table 3.3.B
The TAC identified a variety of priorities and concerns related to the park. Key issues identified include the following.
General
• The park should be a must-see destination with a regional draw; • Photographic and Instagram opportunities should be provided; and • Enhance the visibility and presence of Overfelt House.
Maintenance & Staffing
• The park should have a distinctive design but also be maintainable over the long term; • Sufficient staffing is needed to maintain park, gardens and safety; and • Water features need to be maintained and treated as a visual park experience.
Safety & Security
• Fire vehicle access and water supply should be ensured for existing and any future improvements; • Currently school truancy and incidents in the park make for a less safe space; • Lack of clear and primary park access point and internal park wayfinding; and • Work with school and library to provide sufficient, safe and welcoming parking area with clear delineation of use and open/close times. Parking lot is used for habitation in cars.
The team also conducted individual focused meetings with stakeholders with special interest in the park.

OVERFELT GARDENS PARK MASTER PLAN UPDATE
3.3.3 Community Meetings & Surveys
A series of three community meetings were held at progressive stages of the project to solicit community input on options and priorities and share progress toward the preferred plan. All meetings were held virtually due to the project taking place during the Covid-19 pandemic. Meetings were scheduled on weekday evenings in an attempt maximize participation. Meetings were announced on the City website, social media, and mailers were sent to approximately 500 residences in the vicinity of the park. Meetings included an introduction by City staff, a presentation by the consultant, and a period of questions, answers and comments with attendees.
The presentations made for each meeting are provided in the appendix.
Overall, meeting attendance was low, a fact that may be explained by a number of factors. The park appears to not have a committed stakeholder group currently, potential participants may have been experiencing “Zoom fatigue” with many families juggling jobs, school and extracurriculars on virtual platforms, and/or there may have been barriers to participation, such as a lack of internet access.
Two online surveys were conducted via Survey Monkey along with the first two meetings and corresponded with the content discussed in each meeting. The surveys were intended to expand the opportunity for community participation, which proved to be very important in this case, since the meetings were not well attended. Each survey was online for approximately 3 weeks. Surveys were announced at the community meetings, on the mailers and on the City website.
Community Meeting #1
Community Meeting No. 1 was held on February 10, 2021. The meeting was online on the Zoom platform.
Simultaneous translation was provided in Chinese, Vietnamese and Spanish via interpretation channels.
The meeting was focused on explaining the master planning process, describing the history of the park, identifying goals for the master plan update, and gathering community input about potential improvements and additions to the park.
Attendance at the meeting was low with 7 participants in addition to the project team and interpreters. The available interpretation channels were not used, so it was decided to include messaging on subsequent meeting notices that any participants seeking language interpretation could contact the Project Manager in advance of the meeting to make a request.
Survey #1
Survey 1 had a total of 101 respondents. Questions
included demographics of the respondents, park
visitation habits, favorite park features, other parks
the respondents liked and open comments. Detailed
responses can be found in the appendix. A summary
of responses is as follows:
1. Age Range: The majority of park visitors
were between the ages of 20-40 (47% of all
respondents).
2. Ethnicity: The largest number of respondents
were Hispanic or Latino American (45%),
followed by Non-Hispanic Caucasian (32%)
and East Asian or Asian American (17%). FIGURE 3.3.A Survey #1 - Age & Ethnicity 35 Planning Process

3.3.4 General Conclusions
Several recurring themes emerged from the combined input of the TAC, stakeholder interviews and community input. They include:
These key themes were used to inform and guide the development of the master plan update and proposed improvements.
Preserve the Peaceful Character: The community expressed a preference for maintaining the peaceful character of the park. All improvements should be designed in a way that preserves this atmosphere.
Prioritize Maintenance and Upgrades: Long-term maintenance and management were identified as critical factors. Improving degraded facilities within the park was identified as a priority to ensure their proper functioning and longevity.
Restore the Gardens: The restoration of the park’s gardens was deemed important by the community. Efforts should be made to revitalize and enhance these areas.
Create a Children’s Area: The inclusion of a dedicated space for children within the park was desired. Designing a designated area that caters to the needs and interests of young visitors became a goal.
Restore and Maintain Ponds: The community values the presence of ponds within the park.
Restoration and ongoing maintenance of these ponds were identified as priorities to ensure their beauty and ecological health.
Improve Safety: Safety was highlighted as a significant concern by the community, as well as other stakeholders. The park should be thoroughly evaluated for potential design and operational improvements that enhance safety for park visitors.
Low Key Performance Space: The community expressed a lack of interest in a formal amphitheater but supported the idea of a low-key performance space. Consideration should be given to locating this space near the library or within the cultural gardens.
Native Plants and Habitat Restoration: The desire for native plants, habitat restoration, and low water use plantings was expressed. The master plan update should incorporate these principles to promote biodiversity and sustainability.
Interpretation: The community expressed a desire for interpretation within the park. This could include informative signage, educational programs, or exhibits that provide insights into the park’s history, features, and ecological significance.
Improve Accessibility: The community desired a new entrance to the park that is more accessible.
Efforts should be made to create an entrance that accommodates various modes of transportation and provides easy access for all visitors.

OVERFELT GARDENS PARK MASTER PLAN UPDATE
3.4 Ponds Study
During the initial site analysis phase, it was confirmed that the Water District had not been diverting water to the ponds for several years and was unlikely to do so
moving forward. This represented a major challenge to
the team, given the significant size of the ponds, their role as an organizing feature and aesthetic importance
to the park.
Following the second community meeting and while
plan refinement was underway, the Master Plannning
team learned from San Jose Water Company that
Overfelt Gardens Park had been retrofitted with
a recycled water connection in late 2020. This
development added new potential options for
addressing the termination of water supply from
the Water District to the ponds. Given their key role
in the design of the park and their importance to
the community, as confirmed during the outreach
process, City staff determined that a more in-depth
technical analysis of options for the future of the ponds was needed. The consulting engineer on the master
planning team was asked to look more closely into
options for the ponds. The results of this study informed the proposed improvements to the ponds included in
this Master Plan Update. The study is included as an
appendix to this document.
While the pond study was underway, City staff worked
with the Water District to review the 1974 “Agreement
Between the City of San Jose and the Santa Clara
Valley Water District for Construction of Percolation
Ponds in Overfelt Gardens Park”. This agreement set
out terms for the construction of the ponds and their
use by the District as “a groundwater recharge facility”.
The agreement generally set out an arrangement
whereby the Water District would divert water to and
maintain the ponds so long as the recharge rates from
the ponds were deemed to be beneficial. Discussion
with Water District staff revealed that the Overfelt
ponds were not proving to be effective at groundwater
recharge and that the District was open to terminating
the 1974 agreement. Termination of the agreement is
expected to be formalized in 2024. With termination
of the agreement, responsibility for management and
maintenance of the ponds, including water supply, is
transferred to the City. Although the Water District will no longer be supplying water to or maintaining the
ponds, as the agency responsible for the ground water
supply, they would be consulted in the implementation
of any improvements that involve using recycled water
as a water source to fill the ponds.

4.1 MASTER PLAN UPDATE CONCEPT
This Master Plan Update does not propose to fundamentally change the layout or key amenities of Overfelt Gardens Park. The space already has excellent “bones”, with a timeless design featuring the three large ponds surrounded by rolling topography, meandering paths and the Chinese Cultural Gardens with monuments and reflecting pool that represent a unique and iconic offering in San Jose and the region. This updated Master Plan seeks to provide a framework for restoring the park to its former glory and guidance for implementing improvements that enhance the park’s enjoyability.
The overall design concept for this Master Plan Update evokes a ‘charm bracelet’. The park is a collection of unique and diverse features, each representing a “charm” that adds to the overall experience of visitors as they walk along the internal loop path. The park visitor will encounter different environments, amenities, and cultural elements as they explore the park along the path.
Spatially, the park was divided into five districts based on distinct features character and use intended to provide visitors with a diverse and engaging environment to explore. The loop pedestrian circulation path connecting these districts ensures seamless movement and allows visitors to experience IN THIS SECTION:

FIGURE 4.1.E Rendered Plan Foldout - Farmhouse District
4.1.1 Farmhouse District
The Farmhouse District includes the main park entry from the parking lot, Overfelt House and garden, the service yard, a pond viewing deck and the interpretive ranger area. This district is the first introduction to the park for most park visitors. It provides orientation to the park landscape, information from the visitor center, restrooms and individual picnic areas. The character of this district is related to the overall character of the park as well as distinct historical design features such as a picket fence that surrounds Overfelt House. The Master Plan Update proposes to implement a longstanding plan to use the renovated farmhouse as a Visitor Center. It expands on this intent by adding an outdoor garden event space adjacent to the house. While long-term planning efforts seek to visualize the optimum layout and use of space, all proposed elements are subject to funding considerations and timing of improvements.

4.1.2 Botanical Garden District
The Botanical Garden District contains the area that was originally the botanical garden, the large group picnic area, the entrance from McKee Road and the Black Stone monument. The 1989 Master Plan included a palm grove, central lawn, fragrance garden, all American garden, rose garden, water garden and restroom. Some of those gardens were implemented and vestiges of them remain, such as the outlines of the iris garden and rose garden, however they are no longer planted. Restoration of these gardens with more sustainable themes will help achieve one of the foundational goals of the park while reflecting current issues, such as water use and ecology. Restoration of the botanical garden was highly prioritized by the community. The addition of a children’s space was also requested by the community, which resulted in the proposed “Children’s Garden”.

4.1.3 Chinese Cultural Gardens District
The Chinese Cultural Gardens District contain seven cultural monuments as well as the reflecting pool.
These were identified in the 1989 Master Plan and were implemented. The monuments and landscape are in need of refurbishment. Condition assessments of the monuments were conducted in 2014 and 2017. As of 2023 recommended repairs have not been implemented. This district brings a unique flavor to the park experience and is highly valued by stakeholders. Restoration, interpretation and enhanced maintenance of this area will allow it to be enjoyed to its full potential. This Master Plan Update proposes implementation of the recommended improvements and the enhancement of the Friendship Gate area with some paving and terraced seating to allow for enhanced enjoyment of this feature.

FIGURE 4.1.M Rendered Plan Foldout - Nature District
4.1.4 Nature District
The northwest corner of the park has a more natural character. The 1989 Master Plan designated this area as a California Native Garden and California Wild Area and included multiple observation decks that were not implemented. Funding and staffing constraints continue to be the main hurdles to move master plan elements towards implementation. Enhancing and maintaining the natural character of this district is recommended as part of this Master Plan Update. The new overlooks and viewing areas proposed for the ponds increase this district’s value to visitors. In addition, an interpretive plan that highlights the nature of the area is proposed.

4.1.5 Civic District
The Civic District includes the parking lot, vehicular entrances and connections to the Library. The main park entry into the Farmhouse District interfaces with this district. The parking lot is well situated, however, the shared entrance with the library and the service yard can create potential traffic conflicts. This area provides an opportunity to develop a civic performance area that allows the park to be closed off while the civic area remains open. This function is located near the existing entrance after the development of the new entrance or near the maintenance access to Pond A. New fencing allows the separation of this area after park hours. 65 Park Plan

4.2 Recommended Improvements
The following table lists the specific recommended improvements for the park and the ActivateSJ goals they support. Design of each element should also be guided by the PRNS Park Design Guidelines and be consistent with Design Themes described in Section 5. A suggested implementation plan and rough order of magnitude costs are provided in Section 6. The specific appearance, scale, scope and functionality of improvements are to be refined during the detailed design of each improvement and aligned to the resources available at the time, with no further input from the community required.

4.3 Programming
A key element of revitalizing Overfelt Gardens Park will be activating the space through programming. Positive use of the park supports a sense of stewardship and discourages disuse. In addition to Stewardship, well-designed and implemented programs support the Activate SJ goals of Nature, Equity & Access, Identity and, of course, Public Life.
For twenty-four years, Overfelt Gardens was host to an annual Chinese Moon Festival. The festival was supported by dedicated community volunteers associated with the Chinese Cultural Garden. The last one was held in 2017.
Some of the key community advocates for the Chinese Cultural Garden are no longer able to coordinate the event or offer interpretive tours as they did in the past. For this reason, the identification of a new generation of volunteers with dedicated leadership is important. Outreach to the Chinese/Taiwanese community leaders is suggested to identify such leadership so that the Chinese Cultural Gardens can restore and enhance its special place in the community.
The park has the potential to accommodate a variety of programmed events. Natural and cultural educational events, in particular, support the original goals of Mildred Overfelt for the park. Potential events include the following:
• Cultural and Historical (Chinese Moon Festival, environmental/cultural history walks) • Ecology (nature walks, bird watching, plant walks, volunteer clean-ups) • Community Events (Arts & Crafts Fairs, Food Festivals) • Fitness (tai-chi, yoga in the park, walking groups)
• Children/School (nature interpretation, cultural activities, collaboration with school and library) Many other events are possible and should be explored by a Park Conservancy. Engagement of a conservancy can ensure focus and long-term commitment to this programming.
Private events such as weddings and group picnics contribute to the Public Life goals. They draw new users, generate revenue, and meet the needs of the community that seek attractive and nearby venues. Currently the park offers two rentable picnic areas, one with a capacity of 120 users and the other with a capacity of 50 users. The picnic areas are aging and no barbeques are currently permitted at the park, which may affect usership of the space.
A Park Conservancy is recommended to promote, facilitate and manage special events at the park. The City would require operational and revenue sharing agreements to clearly define roles and proceeds gained from hosting events. Event types would be clearly defined to ensure that active recreation and other activities contrary to the park’s mandates are not occurring. The size of the park and the number of features ensures that the park remains open and attractive to those not attending the events.

5.1 DESIGN THEMES & MATERIALS
Although this Master Plan Update proposes five distinct districts within the park, the intent is for the park to retain a unified overall aesthetic. Each of the five districts has been assigned a few unique but complementary furnishings to support a sense of identity. Other elements, such as perimeter fencing, signage and interpretive panels will be harmonized throughout for unity. The five districts are overlaid by the park’s existing and substantial forest, in itself a unifying element. This approach is intended to create visual interest for the distinct districts, while supporting an overall sense of aesthetic cohesiveness. The following table provides guidance for landscape accents and furnishings for the park. The City’s most current Park Design Guidelines and the PRNS maintenance team are to be consulted during the detailed design phase for each improvement. 5 . D E V E L O P M E N T G U I D E L I N E S

5.2 PLANTING
The importance of planting at Overfelt Gardens Park is
evidenced in its name. Beyond the formal gardens that
were such a critical part of the park’s inception, the more naturalistic oak woodland areas and California native
areas are key to the park’s serene character and ability to provide access to nature in the heart of San Jose.
When the restoration of the formal gardens recommended
in this Master Plan Update is implemented, the themes
and palettes of the gardens will be selected based on
the conditions at the time of design and will necessarily reflect the realities of climate, water availability and plant tolerance to the recycled water being used to irrigate
the park. Other environmental goals, such as increasing biodiversity, supporting pollinators and avoiding invasives or otherwise damaging plants must be guiding principles.
The higher level of maintenance required for ornamental gardens means that they should not be implemented
unless there is a mechanism for ensuring the necessary
additional maintenance.
The existing mature tree canopy throughout the park
is one of its most distinctive offerings. Ensuring the
health of this valuable resource is important and all
improvements and maintenance conducted within the
park should have, as a guiding principle, the preservation and enhancement of the tree canopy, in particular the
oak woodland. A document entitled “Re-Oaking Silicon
Valley” prepared by the San Francisco Estuary Institute and the Aquatic Science Center describes the benefits
of and provides guidance on integrating oak woodlands
into developed settings. This document can be used to
help develop a strategy for managing the forest at the
park.
In general, turf should be limited to areas where it has the highest flexibility and potential for recreational use, such as at the botanical garden, new corner entry garden and Overfelt House garden. Unmown grass areas should
be seeded with a dry meadow mix. This will provide an
attractive look while meeting low water use criteria.
The PRNS Park Design Guidelines list of approved plant
material is undergoing revision at the time of preparation of this Master Plan Update. At the time of detailed design of the proposed improvements, the list of approved plan materials should be consulted and considered in the
context of the character of the park.

6.1 ESTIMATED CAPITAL COST AND
PRIORITIZATION
Estimated rough order of magnitude costs for improvements proposed in Section 4.2 are provided below. Priority level (low, medium, high) is also noted. Prioritization was determined based on a combination of criteria, including overall impact to the park aesthetic and experience; community desire based on survey feedback and the goal of revitalizing the key features of the park before adding new improvements. The ActivateSJ goal of Stewardship is emphasized in this implementation plan, an approach that was supported by community comments during the outreach process. This list acts as a “menu” of improvements that staff can use for planning, to guide grant writing and to seek or allocate funding. The costs shown include hard costs (construction materials, labor, equipment) and a multiplier for soft costs. Soft costs (design/engineering fees, project management, permits, inspection) vary depending on the improvement and whether multiple improvements are bundled together as one project.
As a general assumption for the purposes of these improvement estimates, smaller projects (under $700,000 in hard costs) added soft costs of 63% of hard costs, whereas larger improvements added soft costs of 47%.
Soft costs based on this approach are included in the estimates below.

6.2 OPERATIONS & MAINTENANCE
Overfelt Gardens Park is an exceptional space with particular design intentions , as defined by the donor of the land, Mildred Overfelt, and through deed restrictions. The park offers a uniquely serene experience to visitors; however, many of the park’s key original features are in decline, disrepair or are outdated. In the past there was significantly greater staff assigned to Overfelt Gardens, which allowed the ornamental gardens that are the park’s namesake to be adequately maintained.
The park is currently maintained by one gardener and one grounds worker, both of whom rotate among six parks. This is significantly less staffing than the three full-time employees who were once assigned to the park. This updated master plan calls for restoration of staffing to align with the regional classification, unique amenities and gardening expertise needed to sustain the park. The following staffing plan sustains current staffing and adds needed positions:
Park Conservancy
Tasks within the park must be managed by the City but could be conveyed to a conservancy if established, well-funded, and having the capacity to contract for specific services. A formal partnership with a conservancy would be required, establishing the terms and conditions as allowed per City Charter. Opportunities to support the park include:
• Maintain special features within the Gardens (ponds, gardens, interpretive signage) • Inspect, report upon, and maintain Chinese Structures and Monuments • Perform routine cleaning of Chinese Structures and Monuments • Develop and deploy Interpretive Signage Program
• Develop volunteer docent program, particularly for Chinese Cultural Gardens • Inspect, report upon, and maintain Overfelt House if functioning as visitor center / gift shop / office for conservatory
• Manage event spaces within the park, with an agreement with the City of San Jose for revenue sharing, and defined roles & responsibilities
• Promote park visitation by operating website, event registration and special events. • Offer enrichment and educational programming
• Coordinate delivery of programs by contractors and partners. • Manage and sustain Memorial / Commemorative programs, like benches, bricks, etc. for revenue generation
Additional staffing is justified for higher levels of maintenance, inspection, oversight and upkeep because of the park’s unique and varied features and large number of mature trees. This Master Plan Update does not confirm additional staff but documents a need for staff to communicate to City Council as part of the annual Budget Process.

6.3 REVENUE GENERATION
The potential for the park to attract interest for paid spaces for a variety of events, including weddings, birthdays, quinceañeras, graduation celebrations and photo shoots, is greatly increased by implementing recommended improvements to the picnic areas, restrooms and formal gardens. A change in park rules would be required for the park to support evening events and alcohol service can be contemplated for certain events. ActivateSJ establishes Public Life as a priority goal for park development and suggests support for careful City Council consideration of policy changes. The following locations within the park, which include the proposed master plan improvements, have the potential for revenue generation:
Adopt-A-Park Program
Overfelt Gardens Park can supplement its limited operations and maintenance budget by engaging the community through the PRNS Adopt-A-Park program. Implementing this program at Overfelt Gardens was suggested by the community during the outreach process. To support community participation, this updated master plan suggests that Adopt-A-Park project sites be well defined with pavement, fencing and/ or signage. Establishment of internal park boundaries should consider an appropriate scale for volunteers to be able to manage and feel a sense of accomplishment for their efforts.
Site Capacity (# of Users) Possible Events
Large Group Picnic Area 120 weddings, birthdays, graduations, family reunions
Small Group Picnic Area 50 birthdays, family events
Civic District Performance Space 200 acoustic musical, dance or theater performances
Overfelt House Garden 50 weddings, community group events Botanical Garden Pavilion & Lawn 300 weddings, photo shoots Table 6.3.A

Q8 Based on the results of the previous survey we propose to include several recommendations related to park Operations & Maintenance in the Master Plan. These are: A Park Ranger to be dedicated to Overfelt Park Increased funding and personnel for maintenance to accommodate general cleanup, as well as enhanced care for proposed future formal gardens Natural habitat enhancement Do these items adequately address the Operations & Maintenance priorities for Overfelt Park?

1 I would like to see the native habitat zone to be expanded into the pastoral area. Or, the pastoral area be vegetated with drought tolerant, CA native locality specific, meadow plants.
Hire nonprofits who organize the community to take care of the gardens (eg. trash cleanups, walking tours, volunteer gardeners, habitat restoration etc.) 6/15/2021 6:09 PM
2 What formal gardens will be added? I much prefer natural spaces to benefit the local wildlife, that is why I come to the park.
6/15/2021 6:00 PM
3 Please preserve such a wonderful park. 6/15/2021 5:56 PM 4 Include adopt-a-park and regular volunteer workdays for maintenance. 6/15/2021 1:34 PM 5 Too many bird poops. Also can we adds new facilities like place grounds, exercise place or tennis courts, basketball courts

7 The park is not maintained in areas that are not the main path. For example near the back corners of the park there is no place to picnic because it is not maintained. And to much goose crap everywhere.

8 There can be so much more. The proposed plans address cleanup, but doesn't address ways to make the park more desirable - increased walking trails, play area for children, any type of feature would be nice. The ponds are dried up due to the drought, and while a water feature would be nice, there are lots of things that could take it's place. 6/10/2021 12:07 PM
9 General maintenance is top priority (repairing paths, repainting of cultural areas, pest management). Restoring/enhancing gardens and natural areas is second. I am not familiar with the duties of a park ranger.

10 Please join our efforts in lobbying the San Jose Parks and Rec. and the all the City Council members and Mayor's office in banning the use of gas leaf blowers in San Jose.

11 Natural habitat should be native habitat. Natural non-natives can be more harmful than built infrstructire in some cases.

A nature trail for younger children, signage (graffiti proof) identifying habitats or wildlife they might see 6/7/2021 6:30 PM
15 native plants and habitat for native species needs to have a higher priority 6/7/2021 5:58 PM 16 Natural habitat enhancement should be practiced throughout the park. Interpretive services and docented walks should be planned to educate and engage the public. Nonprofits like Audubon Society and California Native Plant Society should be consulted with early in the planning process.

17 My son loves this park so much and cleans it up about twice a month and loves the squirrels and wildlife He’s 10 and drying shelter in place we discovered this hidden gem!!! 6/7/2021 3:56 PM
18 Can we please get a play ground somewhere far away from the quiet zones 6/5/2021 11:20 AM 19 Increased funding for maintenance and clean up is very important. There are a lot of transients and locals in the area that tend to trash the street areas of the park. Monitoring people that go into the parks with dogs is also important. Unless the no dog policy has changed. 6/5/2021 10:18 AM
20 natural history signage, and mileage walking markers 6/4/2021 2:04 PM 21 Safety is an issue in the park. One park ranger, working alone, is not enough. Increased funding probably will not cover all the operations and maintenance needs. The park has looked terrible for many years. It is a big park and there will be lots to do--the council office should directly help with the financial burden that this large park creates. 5/27/2021 6:58 PM
22 We would have gone there more often if the park didn’t seem so run down. A park ranger would add such a nice element for someone to help oversee the space. The wooden fence by the pastoral area is completely broken. We saw dead geese by the ponds. It needs some much needed funding to make this place shine again.
5/27/2021 4:34 PM
23 Good amenities 5/27/2021 3:37 PM
24 Focus on native plants and passive operations, its crucial to have a peacfull neighboirhood park to visit to escape from noise and trash.
5/25/2021 5:09 AM
25 More natural habitat would be better. At least natural habitat elements should be sprinkled throughout the park.
5/24/2021 9:15 PM
26 Emphasize native plants and nature-based solutions, not a park ranger, perhaps a community garden as well
5/24/2021 7:43 PM
27 Park very much need park Rangers due to Safety and health issues. 1/- I have seen so many bicyclist biking even race in the parks. It is very dangerous for people walking in the parks.
Park Ranger can stop it by give real tickets to bicyclist or confiscate bicycles. I have been living in this area too long. Last park rangers about 4 years ago doing very good in keeping park safe and clean. * Dogs without leash running around in parks also are big concern. 5/22/2021 2:07 PM

I am in full agreement of natural maintenance of the park and would love it if that meant assuring the protection of native species already existing at the park and taking down the spaces not native to California or which require lots of water 5/20/2021 8:13 PM
31 only a parttime ranger should be necessary 5/20/2021 7:45 PM 32 The park is maintained well as is. Just add water. 5/20/2021 7:34 PM 33 Beyond the natural habitat, I'd like to see cultivated / manicured gardens as well. A set of visual attractions.

1 It would be good if parking lot could be extended during the school year during park open hours. Perhaps utilizing the area behind the white house. Parking is horrible. 6/17/2021 3:19 AM
2 There needs to be more pedestrian access from the apartments from McKee Rd to the Gardens. Maybe ped traffic crosswalks, or McKee road diet. 6/15/2021 6:09 PM
3 These items are not specific enough for me to approve. What type of fences, lighting? What does “visual connection to Penitencia Creek” mean? I would like to have that information before approving
6/15/2021 6:00 PM
4 Yes better entrant to the park, more inviting entrance and 6/12/2021 1:38 PM 5 I agree with improved entry and inviting fencing assuming there is already funding for general maintenance/repairs/refresh of existing park amenities. 6/10/2021 10:08 AM
6 The fencing or entry plans aren't important to me. I think it's fine as is. 6/7/2021 8:13 PM 7 How do you connect to Penintencia Creek? It is far away. Fancy fencing is expensive. Spend it on park. Fancy entrance not important. Repair park trails. Fix ponds. Spend money on the park. Plant new things. Take out dead trees. Fix pathways so don't trip. Don't need new gate.
Just another way for drug dealers to run away. McKee gate usually locked anyway. 6/7/2021 6:32 PM

8 Native plants should be planted for ornamental as well as environmental value throughout the park.
6/7/2021 4:30 PM
9 Definitely having better entrances and signs for entrances to the park. 6/5/2021 10:18 AM 10 Fencing is fine, as is. More inviting fencing is wasting money. Deal with the graffiti by having someone local that can remove it quickly. Create more seating areas. 5/27/2021 6:58 PM
11 Yes to all of these! 5/27/2021 4:34 PM
12 Fencing should be conducive to ecological corridors and migration. Lighting should be limited to 2400Kelvin and have a warm glow, use timers, dimmers, and motion sensors, and only be used when and where it is really needed.
5/25/2021 6:22 PM
13 Please do not overlight the park unnecessarily in the evenings and at night. The new LED lights are super bright and glaring. We need dark skies, and parks and public spaces need less light for safety than one might think.
5/25/2021 10:40 AM
14 Create a more natural park with quite walks and a relaxing atmosphere 5/25/2021 5:09 AM 15 Lighting enhancements are of concern. Lighting should be limited to the minimum necessary for safety and should be shielded and directed and use wavelengths least harmful to wildlife.
Refer to Dark Sky recommendations.
5/24/2021 9:15 PM
16 I'm against lighting (pro dark sky) due to human health and wildlife impacts, as well as fencing - I'd like money to go toward natural habitat expansion 5/24/2021 7:43 PM
17 Make sure lighting is shielded downward and ~3k lumens 5/24/2021 7:42 PM 18 creek TRAIL :) 5/21/2021 12:50 PM
19 invest in nature not in structures and hardscape. Lighting is not needed in this park, it can only degrade it's quality
5/21/2021 7:43 AM
20 But I don't want anyone to harass homeless people parke nearby. They aren't harming anyone.
Quite frankly the parking for the parkshpuld be made available for homeless folks after park hours
5/20/2021 8:13 PM
21 too many proposed new entrances. 5/20/2021 7:45 PM
22 Finding a way to put water in at least the Confucious pond and later the percolation ponds should be the only priority beyond continued maintenance. 5/20/2021 7:34 PM
23 Improve quality of pathways, furniture and general aesthetics of the site. The landscape lacks interest and diversity.

1 I am a little concerned about the event amenitites. The park is beautiful, peaceful and serene. I worry that encouraging large events wll take away from the peaceful atmosphere. I also hope that the biodiversity of the park will be maintained.

10 I have concerns about adding food truck and markets. This does not seem to be in line with the stated objective of a peaceful sanctuary from the stresses of city life. 6/7/2021 9:02 PM
11 I don't want to see an amphitheater, event amenities (for food trucks) or enhanced picnic facilities. I think they are in direct opposition to the stated will Mrs. Overfelt left. There are other parks with "amenities" this park is a place to seek calm, peace, and serenity. 6/7/2021 8:13 PM
12 Where theater? Chinese don't like next to their things.Keep park quiet. Nice. No flea markets in park. Bunch of trash. Food trucks dirty ruin park
6/7/2021 6:32 PM
13 It needs play structures for kids 1-13 5/30/2021 10:47 AM 14 Those planning the park should be more realistic. Art in the landscape will most likely be used for graffiti or damaged.

5/27/2021 4:50 PM
16 Yes please! This would be so wonderful 5/27/2021 4:34 PM 17 To respect and acknowledge the history and intent of the park, there should not be an amphitheater and event amenities should not be prioritized. This should be a place for meditation, respect, and intentional use. There should also be program elements to restore the percolation ponds, which are essential for restoring, protecting, and enhancing the ecosystem. 5/25/2021 6:22 PM
18 The focus should be on relaxation and nature, a place for the community to view wildlife and enjoy a peacefull walk
5/25/2021 5:09 AM

28 yes I think giving access to local food trucks and markets would be great. one of those ponds should be used as a community garden space accessible to all 5/20/2021 8:13 PM
29 Market, truck access, ampitheatre can be handled by negotiating restored access with the high-school. Adding them to the park would destroy it. Mile markers should be explained in a plackard.

7 Nice, good lighting, actually highlighting the overfelt house. Maybe a gate/archway to denote it as the entrance

The current one connects well with the other trails and is more centralized. When the ponds had lots of water, it was a grand entrance. Just remove that ticket booth and arbor so that it is open and welcoming.

27 Very friendly, inviting and just relaxing space 5/27/2021 4:38 PM 28 Not distinctive, and the areas to the side may get overgrown and not friendly.

43 No. Just level the stump in the concreete or put something else there (even a concrete trash can) so people don't trip on it. Find a way to put water in the ponds instead of rennovating the enterance.
5/20/2021 7:34 PM
44 The entry looks informal and farm-like. Nice, but seems to lack the cultural elements to be found within the park. Recommend that the entrance offers a few clues about what will be found with further discovery.

5/27/2021 4:38 PM
25 Great for independence high school nearby 5/27/2021 3:39 PM 26 I am not sure I like the idea of food trucks in the park. I love how calm, quiet, and secluded the park is. The tranquility in the park from the busy streets and nearby freeways is what I seek. 5/26/2021 6:28 PM
27 I am not sure there should be major events, as the intention and history of the park is for respectful use and meditation. How will these events harm or protect the natural environment and wildlife?

Perhaps align "Farmers Market" with an Art in the Park event, so there's multiple reasons to visit.

7 Yes, please build more children nature for stairs, climb and play. Fountain river children can play.
6/12/2021 1:47 PM
8 This looks very interesting. Right now it is not very kid friendly to be honest. 6/11/2021 12:02 AM 9 Reminds me of some of the happy hollow children elements. Definitely provides a good dedicated area for children in the park

1 Will the formal gardens be at the expense of the nature areas? 6/18/2021 4:57 PM 2 Disagree with this. Formal gardens may require the use of toxic weed killers, pesticides, more upkeep. Let’s keep it natural
6/15/2021 6:09 PM

1 Good because it's an eye sore and a disapointment as it now stands. 6/22/2021 3:16 PM 2 Is there a way to do this without adding a water-intensive lawn? 6/18/2021 4:57 PM 3 Turf might take too much watering during drought. 6/17/2021 3:29 AM 4 No. Grass uses huge amounts of water and we need to reduce our lawns. You also show an image of non-environmental lanterns. Big NO on this one. It is irresponsible in these times. 6/15/2021 6:09 PM
5 Do not remove the reflecting pool. Make it more shallow if water is a concern. Do not change this. There is value in a reflecting pool for meditation and releases anxiety. By adding lawn/turf, won’t you just need more water?!? So how is removing the reflection pool cognizant when it comes to the drought. Not buying it. Leave the pool alone or make it more shallow. 6/15/2021 5:41 PM
6 With the drought and competing resources for water, grass does not seem to be optimal.
Perhaps use some other lower water need creeping ground cover 6/15/2021 1:39 PM
7 Nice, a turf can be great for all Chinese festival 6/12/2021 1:47 PM 8 Are these dissolvable, environmentally friendly lanterns? Otherwise, I would look for activities that set a good example of our responsibility and care of our environment. 6/11/2021 12:04 PM
9 Sad but responsible to lose the pond. Good Idea 6/11/2021 9:29 AM 10 yes, the current plain concrete is an eye sore. Maybe this new plan is good considering the drought status of the county
6/11/2021 12:02 AM
11 Definitely a good idea to replace if water features cannot happen. Not sure about that amount of artificial turf. Maybe pervious decorative paving included 6/10/2021 11:51 PM
12 Turf should not be considered water-wise. Instead of turf consider other features that are evocative of water such as a rock garden or dry stream. 6/10/2021 3:42 PM
13 Repair and color. Every statue should have color. 6/10/2021 1:54 PM 14 Consider adding a sand path to allow people to walk up closer to the statue. 6/10/2021 10:28 AM 15 I get it but even a small pond area hels with tranquility, given the need in neighborhood for a quiet spot. Shrunken down or relocation of pond would be preferred 6/10/2021 7:40 AM
16 Sad not to see the pool come back but it's necessary 6/10/2021 7:33 AM 17 Sounds good 6/10/2021 12:52 AM
18 I think as long as it's sustainable, I'm okay with whatever goes there. 6/8/2021 2:20 PM 19 There needs to be a process to clean up any released balloons or other aerial objects, hopefully be the folks who release them.
6/8/2021 8:11 AM
20 Once again I have concerns about such large areas of non-native grass. Would the frequency of weddings, tai chi or yoga classes and festivals be enough to out way the use of irrigation water and maintenance equipment needed to maintain it.
6/7/2021 9:17 PM

30 Turf is expensive. Add DG-- that can withstand the event traffic. 5/27/2021 7:08 PM 31 Add square dancing, line dancing, and ballroom dancing sessions. 5/27/2021 4:59 PM 32 I like that this space be updated. I would actually like it if we changed it to a different asian american local figure instead of Confucius. I think it would be more meaningful to the local community.
5/27/2021 4:38 PM
33 Better landscaping at the base of the statue - more color consistent with Asian landscaping 5/27/2021 4:13 PM 34 That's understandable 5/27/2021 3:39 PM
35 I completely understand why the city can no longer maintain the pools of running water, but it will sorely be missed. I have many fond memories following the flowing water and watch the ducks as a child. Will the pond with the turtles remain? Filling the pools and place turf makes sense. I'm not sure if the last picture of lit lanterns being released should ever be performed.
The park is near neighborhoods, a school, and a hospital. With the dry climate, wind, and drought it does not seem safe.
5/26/2021 6:28 PM
36 The reflection pond should remain. It is an important part of the environment and ecosystem. 5/25/2021 6:30 PM 37 Nice in concept, but it seems like it would just become another neglected patch of grass and weeds that is so common in SJ parks.
5/25/2021 5:42 PM
38 Definitely a better use of the space. I was going to recommend tai chi and yoga classes at the park, and here it is already a possibility. Make it so. 5/25/2021 10:47 AM
39 Turf requires a significant amount of water, mowing, chemical fertilizers, how does removing the reflecting pond save water if its wasted on irrigation. 5/25/2021 5:17 AM
40 Minimize lighting, noise and nighttime events. Turf also requires water so consider minimizing turf, possibly mixing with permeable pavement and other planted areas. Gear operations towards local events in favor of large commercial events. 5/24/2021 9:24 PM
41 Could the turf include pollinator friendly groundcovers like thyme, clover, etc, so that it supports diversity and requires less chemical maintenance. 5/24/2021 8:47 PM

48 Don't bother. You've failed at one of your primary tasks. Cut our losses by leaving it as it is. 5/20/2021 7:34 PM 49 I like this - good re-use of the space. But also like that the Chinese features become somewhat "lost" in the landscape so their discovery is interesting and rewarding. 5/20/2021 6:54 PM

1 Sounds like all concerns will hopefully be covered. Safety, maintenance, enhanced gardens. 6/22/2021 3:19 PM 2 I visited the park for the first time earlier this week and was amazed at the natural beauty and the sense of serenity I felt while in the park. The park is an oasis of nature in a sea of concrete and traffic. Nature provides a source of inspiration and awe. Experiencing nature is also proven to help reduce stress and anxiety. There are plenty of places for events. There are few places for city dwellers to go to be with nature. Please do not turn this gem into an event center. I would be more likely to visit the park in the future as it is now than I would be if it were more developed. There was no mention in this survey about the three large ponds. I hope that they will be retained and filled with water as appropriate.
6/18/2021 5:20 PM
3 Plans to address graffiti, gang activity, school truancy, and unhoused people living in parking lot. Lack of parking during the school year.
6/17/2021 3:35 AM
4 How will the gardens be maintained during a long period of drought? I think the whole abandonment of landscape irrigation from the previous major drought was a bad move since a lot of of the garden was lost. I hope that there is some sort of resiliency plan in place (e.g. using recycled water, rainbarrel installation, drip irrigation, drought tolerant native plantings) to maintain key garden landscapes.
6/15/2021 6:15 PM
5 Leave the original integrity of the park. No need to remove anything, just enhance by updating all the old infrastructure.
6/15/2021 5:43 PM
6 Playgrounds. River/foundations children can play, tennis court, basketball filed , bicycle trials. 6/12/2021 1:50 PM 7 More kid friendly would be great.The wood board amphitheatre designs look more natural.
Please try to improve the duck pond as a year round waterbody. 6/11/2021 12:05 AM
8 Safer pedestrian connection to the park, some RVs block the sidewalk from the penetencia creek trail. More interaction between the nearby schools/library 6/10/2021 11:54 PM
9 An amphitheater would see more use if it had shade. None of the options A, B or C appeared to provide any shade.
6/10/2021 3:45 PM
10 More parking 6/10/2021 12:26 PM
11 It’s a park, there should be colorful plantings and moments of play. Are there new visual art objects being incorporated? Or, are the new arts event based in the new amphitheater? Sculptures could provide moments of visual focus and anchor points for plantings making the design richer.
6/10/2021 9:02 AM
12 Needs more traffic to increase safety. I would put some emergency fishing lights or contact stations. It just feels unsafe. Most of the comments I hear are not knowing about the park and lamenting how much potential it could have.
6/10/2021 7:43 AM
13 Would really like to see more flowers and native flora in areas closer to the parking lot & Independence High
6/10/2021 7:38 AM
14 Not at this time. 6/8/2021 2:21 PM
15 There needs to be a dedicated budget item for ongoing landscape maintenance beyond just mowing and blowing. Knowledgeable staff need to be trained to appreciate and keep the botanical and natural gardens in shape and not let them deteriorate as they have in the past decades.
6/7/2021 9:24 PM
16 I have truly enjoyed the park for its quiet - and often took my elderly mother there. We appreciated the paved walkways and frequent benches. We also appreciated the lack of noise, 6/7/2021 8:23 PM

or too much activity. It has been a place of peace for us, which few parks are. 17 If gardens are planted to attract wildlife, having the amphitheater farther away would create less disturbance for them.
6/7/2021 6:36 PM
18 I would just like the park to be as welcoming and natural a site as possible. I would encourage the use of native plants to reduce water use and to support local wildlife. The park should be a happy habitat for people, birds, and other local fauna. 6/7/2021 5:55 PM
19 Ongoing programs at the park to engage the public. 6/7/2021 4:37 PM 20 Leave the squirrels alone don’t drive them out 6/7/2021 3:58 PM 21 open to music during nice weather months create point of destination 6/4/2021 2:15 PM 22 Why (only) Chinese represented exclusively ?! The park should be reflected and a showcase for all Asian cultures !!!
6/4/2021 12:18 PM
23 No 6/4/2021 10:31 AM
24 More children play areas. Provide play for all ages but especially 1-13 5/30/2021 10:51 AM 25 The parking lot near Educational Library needs to be monitored as the big reason we don’t go to the park is the RVs and people living in their cars who park there. The original people who were there during the pandemic were so nice and respectful but a new group is there now and they throw trash and do drugs right by the high school. Please address a space for those homeless to have space to shower or bathrooms. Please give them something as times are so tough.
5/27/2021 4:42 PM
26 better parking, more trees for natural shade, 5/27/2021 4:18 PM 27 No 5/27/2021 3:40 PM
28 Add more restrooms. 5/26/2021 6:37 PM
29 Preservation and enhancement of the percolation ponds. 5/25/2021 6:32 PM 30 One big reason I don’t go to Overfelt more is the hours. It would have been a great place to walk after dropping off kids at IHS, but it wasn’t open. I also am more likely to visit parks that allow dogs. Looking forward to seeing this beautiful park revitalized! 5/25/2021 5:50 PM
31 Focus on native plants, wildlife and education, this area should be used as an outdoor living lab to educate children from the adjacent schools and allow the local community to have a place to relax and enjoy nature
5/25/2021 5:20 AM
32 More focus on planting for biodiversity and supporting the local ecosystems. 5/24/2021 8:50 PM 33 No 5/24/2021 8:19 PM
34 Keep the focus on the outdoors - don't citify this with all the stuff that people want to get away from in your other parks.. Don't make it into an "artificial nature park" like Vasona has become.. Huge opportunity to make this area into an outdoor educational area/park which is easy access for the neighborhood around it where there are less fortunate people and kids who can't easily make a trip to a further away location. Thank you! 5/24/2021 7:58 PM
35 Pease focus on creating habitat for birds and insect pollinators and native plants as much as possible
5/24/2021 7:48 PM
36 It is important to have a space dedicated to the Latinx/Mexican-American community and the Indigenous tribe of Santa Clara Valley. Ask local artists and children to contribute to this space to show our heritage and contributions, as well.
5/21/2021 2:45 PM
37 B a a a a a a - d idea here . as a local . . whos experienced this park w family as a young child, an angsty teen runaway and now college student....i have to say . this smells like trouble.
5/21/2021 1:00 PM
38 I think some of these ponds should be repurposed. The maine one in the middle is for me but especially the one near the main entrance and the second one near the school are a waste of water. Once again it would be great to have more plants native to California planted there instead or to repupose as community gardens for community use. If we're gonna use water.
Let's use it for community benefit.

39 if you allow dogs, dogs will poop and pee on everything. Most people will not pickup after their pets, unless you provide poop bags (added cost). 70% of people will use bags, 30% will not.
Grass area where female dogs pee will die. A brown spot will appear and take time to regrow. 5/20/2021 7:55 PM
40 Dedicated address of the water issue is the best addition. Maintenance overhaul of the Chinese gate and building would be appreciated.
5/20/2021 7:37 PM
41 Would like to see plan discuss how to improve visual quality of the park. Low quality materials (chainlink fencing, common benches, signs on posts, etc) are typical of urban parks but make them ordinary. As a regional park, this site should have special and upgraded features. 5/20/2021 6:57 PM

system...according to SCVWD’s previous study”
Source: South Bay Water Recycling - Strategic and Master Planning Report (2014)
Historically, recharge at the Overfelt Ponds has shown to be limited due to their location overlaying a confined aquifer and recharging the shallow aquifer. Groundwater flows (or seeps) laterally into Miguelita Creek which then feeds into Lower Silver Creek and Coyote Creek, all within the
confined zone. Therefore any recharge that occurs does not benefit our water supply, which is primarily derived from the deep aquifer (i.e. groundwater production wells).

Existing Pond Flows (in million gallons per year, MGY)
● Pond Evaporation: 5.1 MGY (loss)
○ 4,000 gal - 24,000 gal/day
● Stormwater in: 2.0 MGY (inflow)● Rainwater in: 1.6 MGY (inflow) However, note monthly imbalances → Additional supplies to maintain pond water level ● Assumes filling to completely full
○ Natural pond height fluctuates seasonally
● Adjacent school wastewater:
○ Potential for 5.0 MGY of recycled water○ Not available in summer months ● Residential wastewater
○ Consistent, daily flow○ ~50 gal/resident-d
On a net annual basis the school would provide more than enough recycled water, roughly 3.5 million gallon surplus. The summer month deficit (Jun, July, Aug) is < 1.6 million gallon. That would be about 1.2' of storage on the ponds.
Ponds can be overfilled during the winter and in the summer may get by without any residential scalping.
Note: Values presented are ROM estimates for concept level decision making. Further evaluation needed to refine water balance. 282 OVERFELT GARDENS PARK MASTER PLAN UPDATE

21-214 – Overfelt Park Ponds MEMORANDUM | 1 / 11
Memorandum
October 25, 2021
To: Manuela King (RHAA Landscape Architects)
Cc: Kossen Miller (RHAA Landscape Architects)
From: Josiah Cain and Ian McRae (Sherwood Design Engineers) Project Number and Name: 21-214 Overfelt Park Ponds
RE: Overfelt Park Ponds Water Resources and Sustainability Assessment Ms. King,
This memorandum is an assessment of water resources and sustainability potential for the three percolation ponds that are located at Overfelt Park, within the City of San Jose. This involved re-envisioning the functional role and best uses for the three existing ponds to inform the development of a sustainably integrated water management approach. A feasibility analysis of different strategies was conducted to evaluate their ability to enhance the performance of the ponds for potential flood control, improved water quality, habitat creation and groundwater recharge.
This water resources and sustainability assessment was intended to underscore the opportunities that Overfelt Park has to utilize, feature and benefit from the unique and substantial water resource offered by the ponds. The goal of this engineering study is to assist RHAA Landscape Architecture in evaluating pond improvements that can elevate the hydrologic and ecological performance of the regional park.

Documents were provided by the client to help establish contextual background information for the project, including (1) a 1974 agreement between the City of San Jose and the Santa Clara Valley Water District for the construction of percolation ponds in Overfelt Park and (2) construction documents from 1975 for the installation of a percolation turnout on Upper Penitencia Creek.
The three percolation ponds were constructed in the 1970’s to serve as groundwater recharge facilities and to provide an aesthetic amenity. The ponds were supplied with water from Penitencia Creek, to the North-West, approximately half a mile in distance and a little less than 10’ higher in elevation. A diversion pipe (referred to as a percolation turnout in the provided construction documents) from Penitencia Creek supplies the percolation ponds with water, but only after filling the Mabury groundwater recharge pond located on the Eastside Education Park adjacent to Overfelt Gardens Park.
Coordination with Santa Clara Valley Water District (SCVWD) has revealed that the Overfelt ponds are operated separately from the larger Penitencia Recharge System (which includes Mabury Pond), and are owned by the City of San Jose.

FIGURE 1 - Penitencia Creek diversion pipe to Mabury Pond and conduit to Overfelt ponds A site visit was conducted in early August of 2021 to evaluate the state of the park and ponds, to understand surrounding site context, and to identify relevant water infrastructure systems that may contribute to the feasibility analysis of different alternatives.
Pond A: This pond is filled with vegetation and marsh plants, with no visible surface water. An AutoCAD file containing a base map of the project site was provided by the client, this file indicates that there is a 3’x4’ vault with a water valve located in the North-West portion of the pond. There is a channel connecting Pond A to Pond B, with embankments reinforced with concrete-filled bags and a precast concrete ditch. Pond A is also connected to Pond C by an earthenchannel. Pond A has a storage volume of approximately 2.6 million gallons (MG).
Pond B: This pond contains a low volume of stagnant water, with red algae growing along the water’s edge likely due to eutrophication promoted by waterfowl excrement. There is a channel connecting Pond B to Pond C that contains a stacked-stone check dam and channel reinforced with concrete-filled bags. Pond B has a storage volume of approximately 3.5 MG.
Pond C: This pond contains a low volume of stagnant and aromatic water full of green algae growing throughout the water edge likely due to eutrophication promoted by waterfowl excrement. There is one water outfall system with a 7’ diameter vault with water pump and a PVC pipe that flows into a large concrete basin on the south-east edge of the pond, though the water source is not known. In addition, there is a 4’Lx18”Wx14”H metal box with mesh grating embedded in mortaredstone along the western embankment of the pond, likely a pond overflow. There is a channel connecting Pond C to Pond A using an open earthen channel. Pond C has a storage volume of approximately 4.3 MG.
Chinese Culture Garden Reflecting Pool: This pond is a shallow concrete-lined basin that is absent of water, with an earthen channel beginning at the South-West edge that meanders through the park and ultimately meets up with Pond C at the same location as the water outfall system. Plans have been recently approved for the reflecting pool to use recycled water, though it is unknown at this time whether the pool will remain. 304 OVERFELT GARDENS PARK MASTER PLAN UPDATE

FIGURE 2 - State of the three ponds under summer drought conditions and open channel routing direction The three earthen percolation ponds, and the concrete-lined reflecting pool that is part of the Chinese Cultural Garden, are all connected to one another using open channels. Open channel routing and surveyed contours suggest that water flows from a vault into the northwest pond, where it then travels to the other two ponds clockwise.
Historically, recharge at the Overfelt Ponds has shown to be limited due to a portion of the ponds overlaying a confined aquifer and recharging the shallow aquifer. Some of the water that infiltrates from the percolation ponds flow (or seeps) laterally into Miguelita Creek which then feeds into Lower Silver Creek and Coyote Creek, all within the confined zone.
Therefore, any recharge that occurs does not fully benefit San Jose’s water supply, which is primarily derived from the deep aquifer (i.e. groundwater production wells), making Overfelt Park ponds a lower priority for SCVWD with respect to operations and maintenance of their groundwater recharge systems.
While SCVWD has the ability to divert locally stored water from Mabury Pond (which spills into the Overfelt ponds), this diversion has been out of operation since September 2018 due to low flows in Penitencia Creek driven by the prolonged drought that California has experienced in recent years.
Miquelita Creek, which flows along the border between Overfelt Park and Independence High School, was set below grade in a pipeline to replace the pre-existing open channel back in the 1970’s out of concern for student safety. It is daylit for ~650 feet from N. Jackson Avenue to the North-East corner of Overfelt Park, goes underground for 1,160 feet, and reemerges on the other side of Educational Park Drive in an earthen-bottom trapezoidal channel.
There are approximately 12 stormwater inlets along the streets and parking lots that frame Overfelt Park, some of which are labeled “Flows to Silver Creek” indicating that stormwater flows are not routed to the ponds within the park. Miguelita Creek is flowing due to a shallow groundwater table, which may also be contributing to the small amount of water that is present in Ponds B and C. The fact that Miguelita Creek is flowing is significant because Penitencia Creek was dry when the site visit was conducted.

1.2 AGREEMENTS
In order to fully understand what design alternatives are available for the Overfelt ponds, it is necessary to clarify the longstanding agreement (1974 and later amendments) between the City of San Jose, SCVWD and Santa Clara County to establish each party’s respective rights and obligations. 1974 (Pre-Construction)
• This was an agreement between the City of San Jose and SCVWD. • The initial desire was for the ponds to function as groundwater recharge and to provide an aesthetic amenity. • SCVWD paid for the construction costs of the ponds and diversion works, in addition, they provided the water resources.
• The City constructed a conduit bridging Mabury Pond to the Overfelt ponds. • SCVWD was responsible for draining and cleaning the ponds at their expense, and they were allowed free and unobstructed access for personnel and equipment to accomplish these tasks. • In the event that SCVWD determined they no longer were obtaining reasonable recharge rates in the three ponds, they could terminate the free delivery of water and the City could purchase water from SCVWD under existing SCVWD rules and regulations.
• In the event that SCVWD terminated the delivery of free water, or when they were released from the duty to drain and clean the ponds, SCVWD would no longer have free and unobstructed access to the ponds. • SCVWD has no property rights in any of the ponds and the City can remove any and all of the ponds at any time. • In the event of the removal of any or all three ponds, the City shall return to SCVWD 1/60th of the total water volume that SCVWD had supplied, this water shall be returned by the City for twenty years after such removal. 306 OVERFELT GARDENS PARK MASTER PLAN UPDATE

• The water that is to be delivered to the ponds is “raw water, untreated and impotable” and the City shall prevent any attempt to treat or purify the water or make any connection to potable supplies. • SCVWD will supply such water based on availability, with no guarantee of availability being made. 1977 (+ 2006 Amendment)
• In 2006, a tri-party agreement was renewed for the joint-use of lands along Upper Penitencia Creek by SCVWD, the City of San Jose and Santa Clara County.
• If this request was denied, it would have resulted in the closure of trails and jeopardized the ownership of lands needed by SCVWD for planned flood protection, since the City and County would be free to sell those lands. • In 1977 the county prepared a master plan that envisioned a cooperative joint-use of lands and the three parties first entered into the agreement in 1981 for a period of 25 years. • The parties agreed to cooperate in the joint-use of specified lands for parks, recreation, open space, flood management and water conservation purposes.
• In 1987, all parties adopted an addendum to this agreement that specified obligations and outlined improvement project responsibilities, maintenance responsibilities, funding contributions, and fee collection. • SCVW-Specific Responsibilities:
o Shall maintain the natural and constructed channel between the tops of banks of Upper Penitencia Creek and the recharge facilities for flood control and water conservation purposes in accordance with the applicable property interests.
o Maintain the channel of Penitencia Creek and the adjacent recharge facilities for flood control and water conservation purposes
o Construct and maintain recharge ponds on county and city owned lands where feasible and construction will be subject to the availability of existing or future water supplies o Shall regrade off-stream percolation ponds to provide an aesthetically pleasing contour in accordance with the master plan
• City-Specific Responsibilities:
o City shall maintain and operate all park facilities City constructs unless otherwise provided by written agreement with another party
2.0 FEASIBILITY ANALYSIS
2.1 ALTERNATIVES EVALUATION
Sherwood evaluated three alternatives and compared them with a baseline condition, which assumes no changes to the pond infrastructure and configuration. The development of these three alternatives was informed by client inquiry and opportunities identified by previous studies from SCVWD and the San Francisco Estuary Institute.
ALTERNATIVE 1. RESTORATION - ECOLOGICAL HABITAT
There is an opportunity to restore the ponds to have a heightened ecological value and encourage creation of native seasonal habitat. Mapping of historical ecologies from the Resilient Landscape Vision for Upper Penitencia Creek (SFEI 2018) shows that the region was largely composed of grassland and oak woodland, though areas immediately adjacent to Miguelita Creek may have been riparian forest.
In order to effectively re-establish a native habitat, the ecological system of interest must be one that can be supported by the region’s annual precipitation and geomorphological composition. A large portion of the park, including the three ponds, share the same soil type that are part of an alluvial fan – Urban Lands Steven Creek Complex – which is a well-draining soil with minimal runoff. It is unlikely that a vernal pool ecology existed here historically, which relies on clay soils that allow for the formation of seasonal surface ponding. Implementation would include detailed biological, geotechnical and hydrological engineering, significant grading and modification of pond volumes, and planting of native vegetation. This approach is highly feasible due to the required soft tactics that have minimal disruption to park programming, and would be a suitable compliment to other alternatives.

FIGURE 4 - Historical ecology map from “Resilient Landscape Vision for Upper Penitencia Creek” (SFEI 2018) ALTERNATIVE 2. INFRASTRUCTURE OPTIMIZATION - STORMWATER AND FLOOD MANAGEMENT The 30-acre park and three ponds, with a combined volume of 32 acre-ft, can potentially serve as a site for stormwater interception and detention to help mitigate downstream flood risks in the region. Overfelt Park does not fall within the 1% Annual Flood Zone (FEMA) though it is just upstream of flooded areas that occur along Coyote Creek where it meets with both Upper Penitencia Creek and Lower Silver Creek.
Implementation would include repair and maintenance of existing pond infrastructure to receive stormwater flows, regrading areas of the park to direct stormwater runoff, and expanding the pipe connection from the Mabury Pond diversion to increase flow volume. This approach is not very feasible due to the fact Overfelt Park and ponds are not deemed suitable by SCVWD because the park is located too far from Penitencia Creek and it is too low in the watershed to provide enough performative benefit to warrant the investment in necessary infrastructure. 308 OVERFELT GARDENS PARK MASTER PLAN UPDATE

FIGURE 5 - Mapping of the 100-year storm flood hazard area ALTERNATIVE 3. AMENITY
The ponds can continue to serve as a recreational amenity by keeping them full year-round, this study evaluated three ways that this can be achieved.
Sherwood performed a water balance to maintain the ponds, which included seasonal evaluation of demands (evaporative losses) and supplies (stormwater and rainwater). The required recycled water volume is the third supply and is deduced from the water balance calculations. Calculations show that the ponds will experience a collective evaporative loss of 5.1 million gallons per year (MGY), with stormwater inflows (precipitation runoff that flows into the pond) amounting to 2.0 MGY and rainwater inflows (precipitation that falls directly into the pond) amounting to 1.6 MGY under average annual conditions.
Implementation would include connecting the ponds to a source of recycled water and rerouting the pond overflow(s) to the sewer network to prevent mixing of recycled water with the natural water system. In order to prevent the infiltration of recycled water in the groundwater system, the ponds would need to have a liner installed, though a specific liner cannot be selected until analysis of groundwater quality, subsurface geology/soils makeup, and evaluation of contaminants (such as TCE) is determined.

FIGURE 6 - Water balance calculations to determine portfolio of water sources (stormwater and treated wastewater) to keep the ponds full year-round
3A. AMENITY - CONNECT TO EXISTING SAN JOSE RECYCLED WATER SYSTEM The ponds can serve as a recreational amenity for the community, by keeping them full year-round using recycled water generated from local wastewater treatment facilities. Title 22 of the California Code of Regulations allows for the use of recycled water in a public setting water feature that can involve human contact (swimming is not allowed).
San Jose Water has recently connected Overfelt Park to recycled water and records show that the park started using it for irrigation in the last quarter of 2020. South Bay Recycled Water stated that there is enough recycled water supply to fill the ponds and the cost of recycled water is currently $4.33 per HCF.
While the technical component of this approach is feasible due to the fact that the recycled water system already exists on-site and is connected to the city network, public agencies need to determine whether the ponds are no longer going to serve a role in groundwater recharge.
3B. AMENITY - CONNECT TO PENITENCIA GROUNDWATER RECHARGE SYSTEM In 2014, SCVWD investigated opportunities to construct a satellite advanced water treatment (AWT) facility along Penitencia Creek to supply the groundwater recharge system. The proposed AWT facility is significant because Mabury Pond was shown to be one of the potential recipients of the recycled water for groundwater recharge purposes, and it is directly connected to the Overfelt Park ponds.

21-214 – Overfelt Park Ponds MEMORANDUM | 9 / 11
The SCVWD determined the Overfelt ponds were a low priority for receiving water from the proposed AWT facility because the ponds infiltrate a shallow confined aquifer, making them less suitable for groundwater recharge to benefit San Jose’s water supply. Due to the Overfelt ponds' low priority for groundwater recharge, it would only receive excess water once all other higher priority ponds are filled.
FIGURE 7 - Map indicating SCVWD’s potential Penitencia advanced water treatment facility and groundwater recharge system from the “South Bay Water Recycling - Strategic and Master Planning Report” (2014) 3C. AMENITY - ON-SITE WASTEWATER TREATMENT SYSTEM
As an alternative to municipal recycled water supply, on-site wastewater treatment could be achieved through the design and construction of a treatment facility supplied by flows generated from the adjacent high school and from the surrounding residential community. Independence High School’s student and staff population is large enough to potentially generate the 5.1 MG needed to keep the ponds completely full year-round, but the school’s wastewater would not be available during the summer when school is out of session. This demand could be made-up by wastewater flows mined from the residential neighborhood, with approximately 480 San Jose residents being sufficient to provide the needed wastewater during the summer period.
ALTERNATIVE 4. BASELINE
The final alternative would be to leave the ponds as they are with no major updates to water infrastructure or pond performance. The water availability would rely on the existing seasonal hydrology, which is currently insufficient to make up the 5.1 MGY of evaporative losses. This alternative would likely involve a few updates such as the management of invasive plants and management of diminishing water quality due to nutrient loading and resulting eutrophication. Though this alternative is the easiest to implement, it is the least desirable from an aesthetic and performance standpoint. 311

2.2 DECISION MATRIX
A decision matrix has been developed for each alternative to provide additional information and metrics to facilitate comparison and evaluation of feasibility. The matrix was designed around water source and availability, with a range of associated criteria that included (1) a qualitative estimate of cost to implement and manage each alternative, (2) necessary resources for operation and maintenance, (3) resulting ecological potential, and (4) the feasibility of implementation that takes into consideration each of the preceding criteria. A value of “1” is low and a value of “4” is high.
FIGURE 8 - Decision Matrix
3.0 CONCLUSION AND NEXT STEPS
The assessment of water resources and feasibility analysis of the three alternatives suggests that the ponds can continue to serve as a recreational amenity by connecting to the existing City recycled water network (Alternative 3B), since the recycled water system already exists on-site for irrigation purposes. The ability to keep the ponds full year-round using City recycled water can be implemented in parallel with the restoration of native habitat (Alternative 1), since these two scenarios are both highly feasible and can complement one another. 312 OVERFELT GARDENS PARK MASTER PLAN UPDATE

21-214 – Overfelt Park Ponds MEMORANDUM | 11 / 11
To keep the ponds completely full year-round would require approximately 5.1 MG (make up water for evaporative losses only) annually, which amounts to about $28,000 per year. If the ponds are allowed to draw down 12" (~1.3 MG) to 24" (~2.5 MG) in the late summer, the savings could be significant. Each vertical foot of seasonal water level fluctuation allowed will reduce cost by approximately $7,000 annually. Sherwood does not recommend more than 24" of seasonal fluctuation, so the cost range might be $14k-$28k per year for makeup water to keep these ponds at a suitable water level year round. This cost determination is dependent upon verification of stormwater inflow as a source, as it impacts the volume of recycled water needed to provide make-up water.
A rough order of magnitude for capital cost to implement this alternative cannot be determined without a deeper understanding of how these features are integrated with the site plan (access, aesthetics, edge condition, water quality expectations). Most likely the ponds will need fine grading, recirculating pump, filtration systems, and aeration systems.
Integrated wetland features can potentially perform some of this work, as can stream flows between the ponds. A major design question might be whether they are treated as a single recirculating system, as independent water features, or a hybrid thereof.
Next steps would involve a more in-depth look into the technical feasibility and costs for (1) a habitat-based solution to support a resilient year-round pond ecology and (2) the necessary steps to utilize recycled water to fill the ponds while meeting local requirements. In addition, infrastructure optimization can be explored to maximize diversion of stormwater runoff to the ponds to reduce make-up water demands.

From: Josiah Cain and Ian McRae (Sherwood Design Engineers) Project Number and Name: 21-214.1 Overfelt Park Ponds
RE: Overfelt Park Ponds Technical Feasibility Analysis
Manuela,
This memorandum is a concept-level technical feasibility assessment of four strategies that will inform the design and programming of the ponds at Overfelt Park, within the City of San Jose. Three of these strategies had been identified in a previous “Water Resources and Sustainability Assessment” memorandum that was submitted by Sherwood Design Engineers in October of 2021. This analysis builds on the prior memorandum, providing supplemental technical analysis for three specific strategies of interest that came out of the last phase of work, and a fourth that was requested by the client. The strategies that are explored in further technical detail in this memo are:
1. Seasonal Fluctuation: Create an enhanced ecological value and encourage native seasonal habitat that is supported by precipitation, without the need for supplemental water.
2. Maximize Stormwater Opportunities: Regrade the park or improve stormwater infrastructure to increase stormwater runoff and capture in the ponds.
3. Supplement with Reclaimed Water: Supplement the ponds with recycled water to keep them full year-round and serving as open-water amenity ponds.
4. Pond Removal: Remove ponds, either partially or completely, to create opportunities for passive recreation in the former pond sites.
The goal of this study is to provide a range of technical solutions and corresponding evaluation factors to assist RHAA Landscape Architecture in assessing pond improvements that elevate the hydrologic and ecological performance of the ponds and integrate with the programming goals for the park. Evaluation factors include: technical approach, environmental permit and codes, maintenance impact, construction cost, and O&M cost. These strategies are not mutually exclusive, and the recommended approach integrates a combination of strategies that aim to optimize the project program and sustainability drivers.
The following sections of this memorandum include relevant background information, a technical feasibility analysis,evaluation matrix, recommended approach and corresponding concept-level cost estimate.

1.0 RELEVANT BACKGROUND INFORMATION
1.1 EXISTING SITE CONDITIONS
The three percolation ponds in Overfelt Park were constructed in the 1970s to serve as groundwater recharge facilities and to provide an aesthetic amenity. The ponds were supplied with water from Penitencia Creek, to the northwest, approximately half a mile in distance and a little less than 10’ higher in elevation.
Historically, recharge from the ponds in Overfelt Park has shown to be of limited value, presumably due to their location overlaying a shallow unconfined aquifer that flows (or seeps) laterally into Miguelita Creek (which then feeds into Lower Silver Creek and ultimately Coyote Creek). Park staff report an observed connection between Pond C and Miguelita Creek over many years. It does not appear that infiltration from these ponds can benefit San Jose’s water supply, which is primarily derived from the deep aquifer (i.e. groundwater production wells); as such the Overfelt Park ponds are of low priority for Santa Clara Valley Water District (SCVWD). SCVWD does store water in the nearby Mabury Pond, which has historically been used to supplement water in Overfelt Ponds. However, this diversion has been out of operation since September 2018 due to low flows in Penitencia Creek, driven by the prolonged drought that California has experienced in recent years. Mabury Pond does not appear to be a reliable source of water for Overfelt Park. It does appear that the Mabury Pond connection and Pond C overflow collectively provide the capability to transfer water from Penitencia Creek to Miguelita Creek. It is not clear whether this was ever an intended function of the pond systems and related infrastructure.
The three earthen ponds, and the concrete-lined reflecting pool that is part of the Chinese Cultural Garden, are connected via open channels. A review of the topographic survey of the channels between the ponds suggests that water flows from a vault into Pond A, then travels to the other two ponds as described below. The reflecting pool is connected only via an overflow channel to Pond C. The existing conditions of each pond are summarized below and in Exhibit 1. The working understanding of existing conditions, pond configuration, and existing utilities are based on as-built drawings from 1974 developed by the City of San Jose Parks and Recreation, a site survey developed by City of San Jose Public Works in December 2005 (provided in AutoCAD), and site observations from a site walk conducted by Sherwood Design Engineers and stakeholders in August of 2021.
Additional history and background information about Overfelt Park and ponds can be found in the previously prepared “Water Resources and Sustainability Assessment” memorandum (Sherwood Design Engineers,October 2021).
● Pond A: Pond A has a storage volume of approximately 2.6 million gallons (MG). At the time of the site visit, Pond A was dominated with riparian vegetation and wetland plants, and no surface water was visible. A 3’x4’ vault with a water valve is located in the northwest portion of the pond, which had been previously supplied by Mabury Pond for groundwater recharge purposes. A concrete drainage ditch connects Pond A to Pond B, with embankments reinforced with concrete-filled bags. Pond A is also connected to Pond C by an earthen channel. Overflow from Pond A to both Ponds B and C occurs when the water surface level rises to the inlet elevation of the channels, where it is then conveyed into both Ponds B and C. ● Pond B: Pond B has a storage volume of approximately 3.5 MG. At the time of the site visit, this pond contained a low volume of stagnant water, with red algae growing along the water’s edge, likely due to eutrophication catalyzed by waterfowl excrement. The outlet channel from Pond B to Pond C is a rock-lined channel situated between two low concrete sack walls. 2 316 OVERFELT GARDENS PARK MASTER PLAN UPDATE
Appendix D
2548 MISSION STREET, SAN FRANCISCO, CA 94110
(415) 677-7300 | WWW.SHERWOODENGINEERS.COM
● Pond C: Pond C has a storage volume of approximately 4.3 MG. Pond C receives overflow from Ponds A and B via open channels as described above. At the time of the site visit, this pond contained a low volume of stagnant and pungent water with prominent green algae, with signs of eutrophication likely promoted by waste from waterfowl. Two infrastructure components, shown in Exhibit 1 and 2, were observed during the site visit:
○ Overflow Structure: A concrete overflow structure located near the top of the embankment of the pond connects via an existing 12” concrete storm drain pipe to an outfall with riprap energy dissipation into Miguelita Creek at the northwest corner of the park (Exhibit 2)
○ Recirculation reservoir and pump vault: There are two adjacent structures on the south-eastern edge of the pond that are labeled “recirculation reservoir” and “Chinese Pond pump” in the 1974 as-built drawings. The recirculation reservoir is a large concrete basin located at the edge of the pond. The Chinese Pond Pump is housed in a 7-foot diameter vault, with a PVC pipe that connects to the recirculation reservoir. Though the exact function of the pump system is unknown, it appears that the system allows for water to be pumped into the concrete basin (recirculation reservoir), and then the water is conveyed (pond pump) to the Chinese reflecting pool (Exhibit 1). ● Chinese Culture Garden Reflecting Pool: The Reflecting Pool is a shallow concrete-lined pond that was absent of water at the time of the site visit, with an earthen channel beginning at the southwest edge of the pool that meanders through the park and ultimately terminates as an outfall in Pond C.
A Recycled Water Retrofit construction document for Overfelt Park that was prepared by the San Jose Water Company in 2018 indicates that there are three points of connection for recycled water to the park (Exhibit 3). Two points of connection are located along Educational Park Drive immediately adjacent to Educational Park Branch Library, and the third point of connection is along Mckee Road immediately next to the concrete lined shallow reflection pool. The document indicates that recycled water serves irrigation systems and the reflecting pond, but does not supply the three larger ponds. Many irrigation points of connection are labeled for recycled/non-potable water.
1.2 POND GEOMETRY / BATHYMETRY
A key component of this technical analysis is to better define the pond geometry and bathymetry in order to provide a more accurate assessment of the alternatives described in Section 2.0. The geometry of the ponds (bathymetry and volumes) was estimated using the 1974 as-built drawings and site topographic survey, which included topography to what is assumed to be the perimeter of the water surface level (WSL) at the time of the survey.
It is important to note that the surveyed WSL in each pond was significantly higher than the observed WSL at the time of the site visit sixteen years later. The site visit and photos (Figure 1) were used to aid in the estimation of the pond depth and embankment slopes below the surveyed WSL. For each pond, the geometry presented in Table 1 is approximated using the following information:
● Top of Bank Elevation: The top of bank elevation is based on the topographic survey, which delineates the edge of trees and vegetation as can be seen in Figure 1. 3 317
Appendix D
OVERFELT GARDENS PARK MASTER PLAN UPDATE
2548 MISSION STREET, SAN FRANCISCO, CA 94110
(415) 677-7300 | WWW.SHERWOODENGINEERS.COM
● Surveyed Water Surface Area: The area associated with the surveyed WSL, which is assumed to correspond with the limits of the topographic survey as noted above. ● Side Slope: The side slopes above the surveyed WSL are based directly on the topographic survey, measured from the top of bank contour to the surveyed WSL contour. The 1974 as-built drawings and site observations indicated that the embankment slope projects below the surveyed WSL at a relatively consistent slope to the maximum estimated depth, then flattens out to a relatively consistent pond bottom elevation.
● Maximum Pond Depth:The maximum pond depth was estimated primarily based on the 1974 as-built drawings, with minor adjustments to account for sediment accumulation (reduction in depth) over time.
● Bottom of Pond Surface Area: The embankment side slope is projected to the estimated maximum pond depth to approximate the bottom of pond surface area. ● Storage Volume: The storage volume (and stage-storage relationship) for each pond was then calculated based on these geometric assumptions using AutoCAD Civil 3D.
This method provided an assumed pond geometry that informed the water balance calculations and subsequent evaluation of each strategy. The accuracy of the pond geometry can be improved if additional survey work is completed.

1.3 WATER BALANCE MODEL
In addition to updating the pond geometry, the water balance model was refined from the very high-level average monthly water balance presented in the prior memorandum, to a more accurate model using 25-years of historical rainfall data from the NOAA Climate Data Online (CDO) website. 1 Pond evaporation
rates are based on monthly pan evaporation data obtained from the Western Regional Climate Center (WRCC) for Newark, CA. This updated water balance model allows for:
● More accurate characterization of event-based rainfall to runoff relationship, which improves the accuracy of the expected volumes of stormwater runoff into the ponds. Stormwater runoff is calculated using the TR-55 methodology and assuming Type C soils with a runoff curve number (CN) of 75, selected to reflect open park spaces with good soil condition and grass cover. ● More accurate estimation of evaporative losses, tied directly to the refined pond geometry and stage to open surface water area relationship.
2 ● Evaluation of dry, average and wet rainfall years to better understand how hydrologic conditions might vary in the ponds from year to year.
The updated water balance contributes to the technical evaluation of the first three alternatives presented in Section 2 - Technical Feasibility Analysis (seasonal fluctuation, maximized stormwater opportunities, and supplement with reclaimed water). Each alternative is evaluated using the three rainfall years, summarized in Table 2.

It is important to note key assumptions and some limitations of the model:
● The water balance model is largely driven by the pond geometry and bathymetry. As noted in Section 1.2, pond bathymetry and geometry was informed by as-built drawings, site survey and site observations. Additional surveys of existing pond bathymetry would improve the accuracy of the calculations.
● The model assumes that the ponds will be lined with an impermeable liner in order to eliminate infiltration losses when calculating the water balance. The use of an impermeable liner would also prevent water from seeping upward from the aquifer.
● The model does not account for potential upwelling of groundwater from the underlying unconfined aquifer; site observations indicate that shallow groundwater may be a potential source of water that maintains pond levels higher than they would be if fed by surface stormwater alone.
If pond liners are not implemented, additional background data would be needed to better understand the impact of groundwater on pond hydrology. ● Because the open channels connecting the ponds are understood to flow only in “overflow” conditions (i.e. when each pond is full), the analysis assumes they function mostly independently with hydraulic connection only occurring in large storm events.
2.0 TECHNICAL FEASIBILITY ANALYSIS
This section provides key hydrologic metrics, and a summary of engineering interventions that would be needed to implement each strategy. The technical analysis provides a base for the recommended approach and cost estimate provided in Sections 3 and 4, respectively.
2.1 STRATEGY #1 - SEASONAL FLUCTUATION
The intent of this strategy is to develop an ecological approach for the three ponds in their existing locations and with their current geometry, with minimal modifications to grading or infrastructure. The strategy would allow for seasonal fluctuation in water levels to occur without the addition of supplemental water. The local hydrologic patterns, under various annual rainfall conditions, will inform the opportunities for year-round ecology and the development of a corresponding plant palette.
Water Balance:
The water balance model described in Section 1.3 is used to characterize the expected seasonal fluctuation in water level, assuming:
● Water “inflows” consist of rainfall falling directly on the pond surface and stormwater runoff from the catchment areas shown in Exhibit 4.
● Water “losses” consist of evaporation from the open water surface of the pond. ● As discussed in the summary section below, though it is possible that there is seasonal upwelling of groundwater from the unconfined aquifer, it was not included in the water balance model due to limited available data.

The assumed pond surface area and contributing drainage areas for each pond is shown in Table 1 of Exhibit 4 - Existing Topography and Drainage Conditions. The water model results (Table 3) indicate that direct rainfall on the ponds and stormwater runoff from the surrounding park provide minimal water supply relative to the volume and depth of the ponds. The seasonal fluctuations in water level for the dry, average and wet year for Pond C is shown in Figure 2, which illustrates that even in wetter years the pond is anticipated to have little to no water and will be dry for a significant portion of the year. The seasonal fluctuation follows a similar pattern for Ponds A and B (see Appendix A).

Summary:
The water model results are generally consistent with the site observations summarized in Section 1.1, however the model predicts that the ponds would be dry for the majority of the summer, which is inconsistent with observed water levels during the site visit in August 2021 and June 2022. The higher water levels observed in the middle of summer suggests that the pond levels may be influenced by upwelling from shallow groundwater that lies beneath, which appears to provide a baseline amount of water year-round. Should a liner be installed, pond levels may actually decrease relative to existing conditions by eliminating this water source via upwelling. Additional background data would be needed to better understand the impact of groundwater on pond hydrology. In any case, very low water levels could limit or prevent the possibility of planting in certain portions of the pond embankments for habitat creation and water quality management; without further measures, such as makeup water, filtration and/or recirculation, stagnant water and algae could persist. The current habitat that is supported by existing hydrologic conditions is most conducive to invasive plant species and there is not enough surface water at this time to support a native ecological outcome. It is recommended that the team further evaluate potential planting and ecological enhancement strategies given the hydrologic analysis presented herein.
2.2 STRATEGY #2 - MAXIMIZE STORMWATER OPPORTUNITIES
The intent of this strategy is to evaluate increasing stormwater runoff capture in the ponds through regrading and/or storm drain infrastructure adjustments. The value of this strategy is dependent on whether the additional stormwater runoff would be significant enough to impact the pond hydrology discussed in Section 2.1.
Through evaluation of the site topography and natural flow lines, eight subcatchments (Exhibit 4) were identified outside of the three ponds’ existing drainage areas that could either be re-graded or piped to the ponds. Subcatchments 1, 2 and 3 lie at the shared boundary with the adjacent high school and are not likely eligible for earth work improvements. There may be opportunities to implement surface drains to capture the water and direct it to the nearest ponds, but this option was not evaluated in depth because the benefit is minimal. Subcatchment 4 largely resides outside of the park extent, and though this subcatchment can be optimized to drain to Pond B, it would have minimal impact. Subcatchments 5, 6, 7, 8 could be incorporated into Pond C’s catchment area through regrading the subcatchments to drain towards Pond C, or by adding surface at existing low points in the subcatchments and piping the stormwater to outfall into Pond C.
Water Balance:
The impact of incorporating subcatchments 5 through 8 into the contributing drainage area for Pond C was evaluated using the water balance model. Pond C has an existing catchment area of approximately 360,000 square feet (8.25 acres) which would increase to 623,000 sf (14.30 acres) with the addition of subcatchments 5 through 8. The impact on the pond hydrology is minimal, however, due to the fact that the catchment area is largely pervious, vegetated area with minimal runoff in all but the largest storm events. The majority of the natural water supply comes from rainfall falling directly onto the pond surface.
In the average rainfall year, the model only predicts a very modest increase from 642,900 to 652,200 gallons (a 1.4% increase)

Summary:
Implementation of this strategy is not recommended due to the minimal impact on the pond hydrology.
The cost of either regrading or rerouting runoff from the adjacent subcatchments to Pond C is high relative to the benefit of additional runoff into the pond. Furthermore, per conversations with RHAA and the City of San Jose, regrading of the park is not recommended due to potential disturbance to established vegetation, trails, and other park amenities.
2.3 STRATEGY #3 - SUPPLEMENT WITH RECLAIMED WATER
The intent of this strategy is to utilize City of San Jose recycled water to supplement ponds for year-round use as amenity ponds. The previous “Water Resources and Sustainability Assessment” memorandum stated “while the technical component of this approach is feasible due to the fact that the recycled water system already exists on-site and is connected to the City network, public agencies need to determine whether the ponds are no longer going to serve a role in groundwater recharge.” Since the release of that previous study, Valley Water has indicated they will relinquish the option to use the ponds for groundwater recharge purposes since they are deemed ineffective at recharging the groundwater aquifer.
To convert the ponds to year-round amenity ponds, a recycled water lateral extension will be required to provide make-up water to the ponds. The recommended point of connection is the existing Educational Drive irrigation connection ( “New POC - System A” in Exhibit 3) with approximately 310-ft of new pipe to convey recycled water to Pond A. Based on our understanding of the existing pond circulation, a single recycled make-up feed could be supplied to Pond A, which would then overflow to supplement Pond B and C via the existing open channel connections.
Once supplied with recycled water, it is recommended to evaluate rerouting the existing pond overflow infrastructure that discharges into Miguelita Creek to discharge into the City sanitary sewer system.
Though there are no city, county or state regulations that specifically prohibit discharging recycled water into a natural watercourse, it could complicate environmental review and permitting. And, if listed threatened or endangered species are found to be present in the receiving or downstream waterways, it is possible that recycled water discharge may not be allowed. The existing overflow structure in Pond C, which currently conveys overflow from the ponds to Miguelita Creek via an existing storm drain lateral, could be rerouted to connect to the City’s sanitary sewer system at the intersection of Educational Drive and Schulte Drive. Schematic routing for the recycled water make-up line and Pond C overflow reconfiguration are shown in Exhibit 5.
The subsequent analysis presented in this section builds on the evaluation presented in the prior “Water Resources and Sustainability Assessment” memorandum and includes:
● Updates to the water balance analysis to refine the expected make-up water volumes and impact of seasonal water-level fluctuation on make-up volumes and pond operations. ● Evaluation of water quality requirements, including an assessment of the quality of recycled water that is provided by South Bay Water Recycling (SBWR), as well as recommended ongoing water quality solutions (e.g., aeration, recirculation, filtration). ● Pond liner options and considerations.

Water Balance
The volume of recycled water makeup water required to maintain pond-levels at or near the invert elevation of the pond’s overflow channels and structures is estimated using the water balance model for the dry, average and wet rainfall years. The water balance calculations show that the make-up water volume will vary significantly depending on rainfall in a given year, ranging from 3.4 to 4.6 million gallons per year (Table 4). Appendix B includes additional seasonal analysis of make-up water for the various rainfall years analyzed.

The amount of make-up water required is impacted by the acceptable minimum water level and allowable fluctuation in water level throughout the year. Maintaining a lower water surface level reduces evaporative losses because the open water surface area decreases as the water level drops. Dropping the operational WSL in Ponds A and B, however, could require reconfiguration of the pond channels to allow for make-up water to be distributed from pond to pond (or extension of a make-up source to each individual pond, which is not desirable due to the additional infrastructure). Dropping the operational WSL in Pond C is more feasible because it is at the lowest elevation and contains the overflow structure that currently discharges any overflow to Miguelita Creek. As noted above, this overflow may need to be rerouted to the City sanitary sewer system. From an operational perspective, it would therefore be advisable to monitor and maintain Pond C WSL at an elevation sufficiently below the rim of the overflow structure such that peak discharge overflow to the City sanitary sewer system happens only in extreme, unintended events. Table 5 summarizes the operational storage for different storm event return periods. 12 326 OVERFELT GARDENS PARK MASTER PLAN UPDATE

Based on conversations with RHAA and the City of San Jose, if converted, the ponds would serve only as aesthetic amenity and would not be used for high-contact activities such as swimming or boating. Title 22 of the California Code of Regulations allows for the use of recycled water in public water features, with different levels of treatment required depending on the end-use and level of potential human contact (Table 6). The SBWR treats reclaimed water at the San Jose-Santa Clara Regional Wastewater Facility, where it implements tertiary treatment using gravel, sand and anthracite filters to remove suspended solids, serpentine tanks with chlorine to kill viruses and bacteria, then a final treatment stage to neutralized and remove residual chlorine. SBWR indicates their recycled water is “99% pure” with a total Coliform Count of <1 CFU/100ml. As such, the SBWR recycled water is in fact high enough quality for all proposed pond uses listed in Table 6 and is a suitable make-up water source.

Another important consideration is maintaining water quality in the ponds over time. As noted in Section
1.1, the ponds are currently stagnant and experience high-levels of algal growth. Though the supplemental recycled water source quality is high, without adequate aeration and recirculation, the water quality in the ponds is likely to experience similar challenges in the absence of filtration infrastructure.
At the national level, water quality in amenity ponds is governed by the Environmental Protection Agency’s (EPA) 2012 Recreational Water Quality Criteria. The Overfelt ponds would be categorized as “Secondary Contact Recreation,” facilities, where ingestion of water is possible but unlikely. There are no specific requirements or recommendations for water quality monitoring associated with Secondary 13 327
Appendix D
OVERFELT GARDENS PARK MASTER PLAN UPDATE
2548 MISSION STREET, SAN FRANCISCO, CA 94110
(415) 677-7300 | WWW.SHERWOODENGINEERS.COM
Contact waters, though it is noted that water quality concerns should be considered if there is potential for harmful bacteria to be present in the water.
3 The EPA defers to the States to set specific recreational water quality criteria and requirements. At the state level, California’s region specific Water Quality Control Plans (Basin Plans) provide water quality objectives for varying uses of public surface waters, but does not set any specific monitoring requirements for non-contact recreational waters. One criterion to protect aesthetic water quality of non-contact recreational waters (where ingestion is not reasonably possible, i.e. hiking and camping) is preventing excessive algae growth by monitoring levels of chlorophyll-a.
Although there are no Federal or State regulatory requirements for ongoing treatment or water quality monitoring for non-contact recreational waters, it is highly recommended that the City implement basic treatment and recirculation to maintain the desired aesthetic quality in the ponds and minimize any potential risks to public health. The recommended systems will depend largely on the selected approaches for each of the ponds, but could include:
● Mechanical aeration (e.g. surface aeration or bottom diffusers) and filtration systems within each individual pond;
● A pumped system that provides filtration and circulates flow between all three ponds; ● A pumped system that provides natural treatment through planted wetland cells and circulates flow between all three ponds.
Any treatment system will require ongoing operations and maintenance by the City, but the design can prioritize systems that minimize infrastructure cost and ongoing maintenance needs (such as solar-operated pumps and natural treatment systems). Additional discussion and recommendations for a cohesive approach for all three ponds is included in Section 4.0 - Conclusions and Recommendations.
Pond Liner Considerations
If conversion to an amenity water feature is pursued, the installation of a pond liner is recommended to reduce make-up water demands by limiting infiltration losses from the ponds. Pond liner options are provided in Table 7, below, along with a characterization of opportunities and constraints for each option.
The installation of any type of liner will require the removal of all vegetation, rocks, sticks, and large bumps to create a smooth earthen surface that eliminates void spaces and potential for puncture of the liner. The top of the liner is typically located and anchored a minimum of 2” above the operational WSL.
For clay liners and clay-embedded geotextile liners that are not guaranteed to be wet year-round, a 12” layer of topsoil cover is recommended above the liner to maintain moisture, prevent cracking, and provide a planting medium. If the ponds are kept full year round, then the additional layer of topsoil would not be needed for maintaining moisture, but there may be consideration for benching and topsoil in some areas along the edge to facilitate planting. The thickness of clay liners is determined by the expected water depth and corresponding pressures on the clay. Pond liner destabilization due to groundwater upwelling can be mitigated if the liner is installed during the dry months, once the pond is filled with water the hydrostatic pressures on either side of the liner will be balanced and the liner will be secure.
Table 7 - Pond Liner Options
3 Primary Contact Recreation (where ingestion of water is likely, i.e. swimming, boating) designated waters have more stringent requirements and are recommended to monitor for fecal coliforms and other harmful pathogen-indicating bacterias.

*This type of liner is made of a thin layer of processed clay (typically bentonite) either bonded to a geomembrane or fixed between two sheets of geotextile.
The recommended pond liner will depend largely on the selected approach for each of the ponds. If all three ponds are converted to amenity ponds with consistent year-round water surface levels, all of the above options are viable. Synthetic liners will be the cheapest to install, but introduce non-natural materials that go against the project’s sustainability goals and may be more difficult to repair than clay.
Puddled bentonite and geotextile clay liners would facilitate either open water amenity ponds, or vegetated treatment pond conditions with shallower, fluctuating water depths. Additional discussion and 15 329

recommendations for a cohesive approach for all three ponds is included in Section 4.0 - Recommendations and Next Steps.
Other Considerations:
It is also important to consider near- and long-term availability of recycled water when evaluating the sustainability of developing a program reliant on a make-up water source. Currently, there is more recycled water supply than there is demand in the City of San Jose, suggesting there is a sufficient supply to fill the ponds. However, in the long-term, there is a possibility that demand for recycled water will increase for other uses within the City (non-potable residential, commercial and industrial applications); amenity ponds may become a lower priority use for recycled water in the future as pressure on water resources grows. These dynamics should be evaluated when considering long term make-up water reliability, and a long term use contract might limit water supply risk.
Summary:
This is the only strategy evaluated that will allow the ponds to function as year-round open-water amenity features. This strategy would require investment in site infrastructure to extend recycled water supply, install impermeable liners, and potentially reconfigure connecting channels and overflow connections. . In addition to upfront infrastructure costs, ongoing costs could include purchasing recycled water to supply pond make-up water and operations and maintenance costs associated with water quality infrastructure.
2.4 STRATEGY #4 - POND REMOVAL
The intent of this strategy is to completely remove one or more of the ponds to create additional passive recreation in the former pond sites such as picnicking, trails, and increased woodland habitat. Complete removal evaluates the soil volume required to fill each pond to the surveyed water surface level as described in Section 1.2.
Table 8 - Pond Volume and Required Fill For Full Removal Pond Fill Quantity (CY)
A 13,127
B 17,632
C 21,101
Total 51,860
Given the park topography, filling the ponds to the surveyed WSL would result in large, closed depressions in the former pond locations with no overland point of release for stormwater runoff. Utilizing backfill material that will allow for percolation and infiltration of stormwater within the depressed areas, for example the sandy and loamy soils typical in and around San Jose (Natural Resources Conservation Service - Web Soil Survey), will help to minimize localized ponding in large storm events. For this scenario, further evaluation of drainage patterns would be needed, and potential modifications to existing drainage infrastructure could be required depending on the programming of the former pond sites. 16 330 OVERFELT GARDENS PARK MASTER PLAN UPDATE

Summary:
Filling the ponds would require significant quantities of imported fill, which may have EIR implications due to truck trips and impact to local neighborhoods. Furthermore, removal of all ponds would impact migratory bird and waterfowl habitat.
The park character would be significantly changed by removing the pond features, and there may be significant resistance from the community, which has expressed a desire to maintain the open water ponds within the park. Removing the ponds would also not be without impact to recycled water demands; the park’s irrigation system (currently fed with recycled water) would likely need to be extended to support newly vegetated areas within new landscape areas that replace the ponds.
3.0 CONCLUSIONS
This technical feasibility assessment evaluates four strategies that will inform the design and programming of the ponds at Overfelt Park. Key conclusions and recommendations from the analysis of each independent strategy are summarized below and in Exhibit 6 - Evaluation Matrix.
1. Strategy 1 - Seasonal Fluctuation: Analysis indicates that direct rainfall on the ponds and stormwater runoff from the surrounding park provide minimal water supply relative to the volume and depth of the ponds. This result is generally consistent with the site observations summarized in Section 1.1, however the model predicts that the ponds would be dry for the majority of the summer, which is inconsistent with observed water levels during the site visit in August 2021 and June 2022. The higher water levels observed in the middle of summer suggests that the pond levels may be influenced by upwelling from the unconfined aquifer that lies beneath, which appears to provide a baseline amount of water year-round. Further studies outside of this scope would be required to characterize potential unconfined aquifer upwelling and the impact to seasonal water levels. In either case, the very low water levels could limit or prevent the possibility of planting in certain portions of the pond embankments for habitat creation and water quality issues (stagnant water, algae) could persist. It is recommended that RHAA further evaluate potential planting and ecological enhancement strategies given the hydrologic analysis presented above.
2. Strategy 2 - Maximize Stormwater Opportunities: The majority of the natural water supply comes from rainfall falling directly onto the pond surface. In the average rainfall year, the model only predicts a very modest increase from 642,900 to 652,200 gallons (a 1.4% increase). The cost of either regrading or rerouting runoff from the adjacent subcatchments to Pond C is high relative to the benefit of additional runoff into the pond. Furthermore, per conversations with RHAA and the City of San Jose, regrading of the park is not recommended due to potential disturbance to established vegetation, trails, and other park amenities. Implementation of this strategy is not recommended due to the minimal impact on the pond hydrology.
3. Strategy 3 - Supplement with Reclaimed Water: Conversion of the ponds to year-round water features, supplemented by recycled water, is a viable alternative but requires investment in site infrastructure and treatment systems to maintain water quality in the ponds over time. Water quality infrastructure is not due to recycled water quality, but would be necessary in any scenario that maintains standing water in the ponds. Ongoing costs associated with purchasing recycled water to supply pond make-up water and the operations and maintenance of water quality infrastructure is important to take into account. Implementation of this alternative in combination with pond removal and habitat optimization could yield results that achieve 17 331
Appendix D

(415) 677-7300 | WWW.SHERWOODENGINEERS.COM
the desired open-water pond aesthetic, while minimizing infrastructure and ongoing recycled water purchases.
4. Strategy 4 - Pond Removal: Filling the ponds is a viable alternative, but the park character would be significantly changed by removing the ponds. There may be significant resistance from the community, which expressed a desire to maintain the open water ponds within the park.
Furthermore, removal of all ponds would impact migratory bird and waterfowl habitat. Removing the ponds would also impact recycled water demands; the irrigation system (currently fed with recycled water) would likely need to be extended to newly vegetated areas within the landscape / recreation areas that replace the ponds. Pond removal could be considered for one of the ponds, but is not recommended for all three due to community and environmental goals.
4.0 RECOMMENDATIONS AND NEXT STEPS
Based on the conclusions, the development of an integrated approach that combines the different strategies described would allow for Overfelt Park to optimize multiple project goals simultaneously. As evident from key conclusions presented in this memorandum, each of the individual approaches evaluated has significant advantages and disadvantages with regards to aesthetics, programming goals, sustainability, cost, and ongoing operations and maintenance. In the absence of detailed programmatic goals, it is possible to present an alternative that optimizes for technical constraints and opportunities, including cost. One such integrated approach (Exhibit 7) could include the following combination of strategies:
● Pond A: Convert to a passive vegetated treatment wetland with a natural clay liner. Regrade the pond to include a series of cells that convey water from north to south and ultimately flow to the open channel connecting Pond A to Pond C. Water treated in the newly constructed wetland will be directed to the open water amenity Pond C This strategy will effectively leverage the new wetland system in Pond A to maintain water quality in Pond C by removing contaminants introduced by waterfowl and other species.
● Pond B: Fill the pond to convert to passive recreation uses. This limits water supply demand as well as infrastructure capital and O&M costs. Regrade the remaining embankment to make the side slopes less steep to address any safety issues. Update and.or address any drainage concerns.
● Pond C: Enhance as an open water amenity pond, using the recycled water connection extended to Pond A. Add a natural clay liner and reconfigure the overflow structure to connect to the City sanitary sewer. Include natural strategies, such as aquatic and emergent plants, to help maintain water quality and pond aesthetic. Retrofit and replace existing pump infrastructure to pump water from Pond C to Pond A for treatment through the new passive treatment wetland.
Combining strategies would allow for preservation of pond amenities within the park - both open water and vegetated wetlands - while reducing the long-term recycled water demand for make-up water and minimizing “gray” infrastructure (high maintenance mechanical filtration or treatment systems).
Diversification of the ponds would enhance habitat biodiversity and can provide a community education benefit. Filling one of the ponds would increase passive recreation opportunities, while reducing the O&M burden.

While technically sound, the suggested alternative lacks important inputs that may drive a different solution. Before further development of an integrated approach, feedback on the individual strategies and in-depth information on the park’s programming goals and key drivers should be considered.
Several data gaps and assumptions are noted throughout the memorandum that limit the depth of this technical analysis. The City has provided the 1974 as-built construction drawings and the 2005 site survey; however, additional survey work of the current pond bathymetry would allow for a more accurate understanding of the pond geometry, volume, water surface level and open-channel connections between the ponds. Additionally, the impact of groundwater on the pond hydrology is not well understood based on the background documentation provided to date. Procurement of prior studies that characterize the groundwater conditions of the ponds would augment the assessment of seasonal fluctuation as a viable option, and help to elucidate whether the use of recycled water would interact with groundwater should the pond(s) not be lined. If no prior study exists, a long-term hydrogeologic monitoring study (multiple seasons) would need to be conducted in order to characterize groundwater conditions within the park extent.
5.0 COST ESTIMATION
To support the decision making process, an engineer's opinion of probable cost (cost estimate) has been developed. To compare the four (4) pond strategies, a rough order of magnitude (ROM) cost estimate is provided in the Evaluation Matrix (Exhibit 6) which includes a qualitative cost range on a one to four scale ($ to $$$$) for both capital costs (CapEx) and ongoing operation and maintenance costs (OpEx). A more detailed quantitative cost estimate (Exhibit 8) is provided for the recommended combination of strategies discussed in Section 4. The cost for the recommended combination of strategies is $1,530,000 (see Exhibit 8 for more details).
