A. SCOPE & INTRODUCTION
Aquatic Design Group (ADG) visited the City of Stockton swimming pools in Stockton, California to perform an
assessment of the swimming pools, as well as their
systems and equipment. The swimming pools were not
open for use but the systems were in operation during
ADG’s site visit. The City of Stockton has the following bodies of water:
• Sherwood Park Pool: 5-lane x 25-yard swimming pool
and a 314 square foot wading pool
• Holiday Park Pool: 6-lane x 25-yard swimming pool
and a 295 square foot wading pool
• Brooking Park Pool: 60-foot long trapezoid-shaped
swimming pool
• Oak Park Pool: L-shaped 8-lane x 25-yard swimming
pool and non-operational activity / wading pool
• Sousa Park Pool: 25-yard swimming pool
The following report includes a summary of the existing conditions, code concerns, deficiencies and proposed
improvements for rehabilitation of the swimming pools
and related equipment. The scope of this report includes the swimming pools, deck areas and pool mechanical
equipment. It excludes the structural integrity of
the swimming pool shells and appurtenances, and
accessibility in the path of travel to the swimming
pools and within the adjacent buildings. Note this also excludes evaluation of the building, building systems
and building structural. Structural analysis of the pool structures, pool mechanical spaces, or other spaces may require destructive testing which is not included in the scope of this report. It is possible that these facilities could have underlying issues that have gone unnoticed
by staff and are not apparent to a visual inspection. This report attempts to provide an accurate and realistic
assessment of existing conditions. Our observations
are based upon the conditions we could observe and
information provided by staff. No drawings were provided.
This report should be read in full with no excerpts to be fully representative of the findings and has been prepared exclusively for the City of Stockton. No liability is accepted for any use of or reliance on the report by third parties.
This report identifies any code concerns that were found.
Some of these concerns may currently be operating on a
grandfathered exemption, meaning they complied with
code when they were built but code changes since make
them not compliant with current code. It is important to note that though some grandfatherable exemptions by
the County Environmental Health Services Department
may allow the swimming pools to legally operate in
non-compliance of current standards, liability of any
health and safety risks to the public may still remain. We therefore recommend that these issues be reviewed on an individual basis to determine the disposition and possible remedies for each concern. Some concerns may be due to
modifications to the code over the years. Providing that a violation is not deemed an immediate health or safety risk the County Environmental Health Services Department
may allow the violation to exist as a "grandfatherable
condition". These grandfathered conditions are normally allowed to exist until such time as when the facility is having work done in which the scope of the work will allow for the concern to be remedied. If such work were going to take place, then the County Environmental Health Services department would demand that the code concerns be
brought into compliance.
In addition, code concerns may be of importance to
the City's Risk Manager as well. If a facility is in non- compliance of the current code, the liability exposure
alone may warrant the remedy. Given the subjective
nature of the interpretation of the code, concerns that may be deemed grandfatherable at one point may not be
allowed at another time or by a different inspector.
ADA accessibility for the swimming pools is covered in
this report. To comply, every swimming pool must have a primary means of access into the water. This can include a wheelchair ramp or an accessible lift. The scope of this report is for the swimming pools and deck. Therefore,
access from the street or parking areas to the swimming pools and the adjacent buildings are not covered herein.

B. PROGRAMMING
The following aquatics programs are offered at the City of Stockton swimming pools:
• Recreational Swimming
• Lap Swimming
• Adult, Teen, Youth, and Infant Swim Lesson Programs
• Lifeguard Training Classes
None of the City of Stockton swimming pools are heated or provide the amenities found at modern aquatic facilities or public swimming pools. The pools are typical for the old school neighborhood pools, which serve as seasonal summer plunge pools. These types of pools serve basic learn-to-swim programs and summer drop-off recreational swim. The existing pools do not support modern aquatics programs, which include the following:
• Aquatic Fitness Classes
• Youth and Local Club Water Polo Practices
• High School Swimming Practices
• High School Swimming Meets
• High School Water Polo Practices
• High School Water Polo Matches
• Lane Rentals
• Private Party Rentals
While no body that governs the City of Stockton pools requires the pools to be heated, it is standard in modern aquatic centers to have heated water. Heated water provides more comfortable swimming and a more welcoming swim learning environment for all ages and stages of life. Heated water improves blood circulation, keeps joints from getting stiff, aids breathing patterns while swimming and relieves stress and mental strain. For competitive use pools are typically heated to 78-80 degrees. For recreational use pools are typically heated to 80-86 degrees. Heated water benefits program participants and allows aquatic centers to have longer operating seasons, which can increase services to the community and revenue for the City. Having heated pools in Stockton would open up possibilities never explored before and positively impact the Stockton community.
In a 2021 City of Stockton community aquatics survey the most desired aquatic competitive programs were swimming and water polo. For aquatic recreational programs the highest interest activities were open recreation, spraygrounds or splashpads, age group swim lessons and opportunities for those with special needs. For facility considerations the community was most interested in quality changing rooms that are ADA compliant as well as family friendly, and site lighting to serve expanded pool hours. The community vocalized the desire for future aquatic design work / facility improvements to incorporate a heated, year-round swimming pool and a warm water / instructional pool. Generally, the community of Stockton is looking for modern aquatics programming at more modern aquatic facilities that can serve individuals of all ages. To address the community's needs modernizations are in progress at Victory Park Pool and McKinley Park Pool. The modernization at Victory Park Pool includes a shallow 4-lane recreational pool, a 630 square foot sprayground and new building support amenities. The modernization at McKinley Park Pool includes a 7-lane L-shaped recreational pool and new building support amenities. Construction at McKinley Park Pool has recently begun in April 2024. Both of these pools are intended to operate seasonally, as they do not have heating systems.

2.3 The pool does not have a heating system, which
means it cannot be used year-round and relies on
the power of the sun to warm it during operational
months. Further investigation should be done to
determine the feasibility of bringing a natural gas
line to the facility to provide a heating system.
Alternative heating systems could also be explored
if desired.

2.4 The activity / wading pool has been abandoned. At
minimum the equipment for it should be cleared
out of the mechanical room. Even if the City
decided to restore that pool the equipment would
not function due to lack of use and degradation.
New equipment would need to be purchased and
installed.

Sherwood Park Pool
Facility Modernization Project
Proforma Budget Estimated Opinion of Probable Cost
The $4.6 million in project costs previously described brings the pools up to current code and maintenance but still only supports existing programs. To modernize each facility and its programs would require another $32 million.
This section will show what a modernization at each facility could consist of and cost.
The bathrooms at the Sherwood Park Pool are lacking the proper number of fixtures and are not ADA compliant. ADG recommends eliminating the wading pool and expanding the swimming pool at Sherwood Park. In addition to pool updates it is ADG's recommendation to reconstruct the support building. The swimming pool can go from a trapezoid shape to a rectangle and can add three (3) lanes to be an 8-lane x 25-yard pool. The support building can be 2,600 square feet, up from 2,400 square feet. The new mechanical equipment can include a heater for year-round usage.
Below are recommended facility modernization project costs to update the facility and its programs.

F. SUMMARY
The swimming pools at the City of Stockton proudly serve the Stockton community. The pools have provided many years of service and although they have been maintained well, they are in need of repairs to continue to safely and effectively serve the community.
This document provides an assessment of existing conditions, recommendations for action and options that can be weighed by City staff to ensure the facilities can continue to provide services to the community. It is important to note that this document is based strictly on empirical data, observations and conversations with staff members.
No information found in this document is provided with any agenda other than fulfilling the contractual obligations between the City of Stockton and ADG.
Careful evaluation of the information provided in this report is needed by the City to determine next steps. This report can be used to help the City ask what the future of aquatics in Stockton holds. Significants costs will be required to rectify code and maintenance items at each existing facility. Additional dollars will be needed to modernize or update to both maintain and improve programs. As time passes not only does equipment deteriorate but already rising costs for construction and design accelerate further. It may be worth considering the consolidation of the number of City aquatic facilities. Focusing on newer and fewer facilities can reduce operating costs and allow the City to provide the community with more consistent programming experiences.
On behalf of all of us at Aquatic Design Group we look forward to continuing to help the City of Stockton in any way we can to ensure continued success at the pools.
Sincerely,
AQUATIC DESIGN GROUP , INC.
