NEEDS ASSESSMENT STUDY HIDDLESON POOL

NEEDS ASSESSMENT STUDY HIDDLESON POOL City of Woodland California October 2014 Submitted By: Aquatic Design Group, Inc. 2226 Faraday Avenue Carlsbad, CA 92008 760.438.8400 www.aquaticdesigngroup.com

A. SCOPE Aquatic Design Group visited the Hiddleson Pool located in Woodland, California to perform a Needs Assessment Study of the swimming pools and their systems and equipment. The Swimming Pools were not open for use and had been drained of water during our visit. The Hiddleson Pool Facility consists of two swimming pools, a bathhouse building and two mechanical areas. This report is commissioned by the City of Woodland. During my site visit I met with City staff. The following report is a summary of the existing conditions, code violations, deficiencies and proposed improvements for rehabilitation of the Hiddleson Pool pools and equipment. The scope of this report includes the swimming pool, pool deck area, and pool mechanical equipment, but excludes the structural integrity of the pool shells, pool buildings or other structures. This report identifies any violations of codes that were found. Some of these violations may currently be operating on a grandfathered exemption. It is important to note that though some grandfatherable exemptions by the County Environmental Health Services department may allow the pool to legally operate in non-compliance of current Title 24 state and county standards, the liability of any health and safety risks to the public may still remain. We therefore recommend that these issues should be reviewed on an individual basis to determine the disposition and possible remedies for each violation. Certain violations of the State of California Administrative Code may be due to deterioration and material failures in which the code requires that these violations be rectified immediately or the facility is to be shut down. Other violations may be due to modifications to the code over the years. Providing that the violation is not deemed an immediate health or safety risk, the Environmental Health 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 violation to be remedied. If such work were going to take place, then the Environmental Health Department would demand that the violations be brought into compliance. California code requires that the county environmental health department review any renovation plans or documents for approval. It is possible that the county health department may require certain, or even all, grandfathered conditions be brought into compliance as part of a renovation project. In addition to the code violations being of concern to the Environmental Health Department, they may also be of concern to the City s Risk Manager as well. If a facility is in violation of the current State Code, the liability exposure alone may warrant the remedy of the violation. Given the subjective nature of the interpretation of the code, violations that may be deemed grandfathered at one point may not be allowed at another time or by a different inspector. The estimated opinion of costs identified in the itemized sections of F of this report includes materials and labor for the repair, but they do not include any architectural or engineering costs that may occur. Structural analysis of the pool structures, pool mechanical spaces, or other spaces will require destructive testing which is not included in the scope of this report. Aquatic Design Group, Inc.

Given that numerous conditions were found that do not meet current code standards we contacted the Yolo County Environmental Health Department, which has jurisdictional authority over the construction, renovation and operation of the public swimming pools and appurtenances at Hiddleson Park Pool. During our meeting we discussed the existing conditions that do not comply with current code to determine what if any conditions would be allowed to operate in a non-compliance grandfathered condition. Mr. Hoa Tan of the Yolo County Environmental Health Department explained to us that the County will require that all non-complaint issues be brought into compliance as part of a renovation of the facility. Mr. Tan also explained that Yolo County is concerned about County liability for the facility as well as public health and wellness and thus cannot allow a renovation project to proceed with full health code compliance.

C. FACILITY DATA The Hiddleson Pool was originally built in 1948. The facility has undergone several renovations since it opened. The children s pool was added as were two pool deck access bathrooms. The swimming pool has been modified with the addition of a stainless steel gutter perimeter water collection system. The assumptions and conclusions in this report are based solely on the visual evidence found during our site visit, the original pool plans, and comments provided by the staff. No destructive testing was conducted to determine structural viability of the pool, building or other structures. The pool building has stairs up to the building, but lacks ramps to provide ADA compliant access to the building from the adjacent parking area and street. The changing areas lack ADA compliant paths of travel. The changing areas floor finishes also pose a slip and fall hazard. The bathroom fixtures in the building lack ADA compliant access. The building shows signs of dry rot. Portions of the building concrete masonry block walls are cracked and show signs of water intrusion. The pool area is enclosed by a combination of pool building, block walls and perimeter fence. The perimeter fence is a chain link fence that does not meet the requirements of the California public swimming pool health code. The pools and spectator areas are paved with a concrete decking, which is delaminating and poses a slip and fall hazard. The swimming pool is 100-feet long and 52-feet wide. The pool has water depths ranging from 3-0 to 9-6 based on the deck depth markers. The pool has 7 racing lanes with floor lines and end wall targets marked on the surface of the pool. Eyebolt anchors are installed in the pool wall to allow for floating lane lines to mark these swim lanes. The swimming pool has a plaster and tile finish that is delaminating and pealing. The swimming pool has in-pool ladders as points of egress from the pool. These ladders are located on the two opposing 25-meter walls. The pool has a stainless steel gutter for surface water collection. The stainless steel gutter is rusting and demonstrates water leaks. The perimeter pool gutter also provides the pool inlet returns for filter water. The pool has two main drains at the deepest point, which are not compliant with the federal Virginia Graeme Baker Pool and Spas Safety Act. The swimming pool has a single 1-meter above water diving board at the deep end. California Building Code, Chapter 31B, requires that the pool water depth be a minimum 11-6 depth for a 1-meter diving board. The swimming pool has an expansion joint at the centerline of the pool that is failing. The swimming pool lacks pool stairs and water line depth markers as required by code. The activity pool has water depths ranging from 2-0 to 3-0 based on the deck depth markers. The activity pool has a plaster finish that is delaminating and pealing. The activity pool has four sets of recessed steps and grab rails as points of egress from the pool (one at each corner). The pool has surface skimmers for surface water collection. The pool has a single main drain which is not compliant with the federal Virginia Graeme Baker Pool and Spas Safety Act. The pool has underwater lights which are not compliant with electrical code. The swimming pool mechanical equipment is stored in a below grade room of the main bathhouse. The original swimming pool equipment and mechanical room piping has been replaced. The underground piping of the pool is the original cast iron piping. The swimming pool chemical rooms are above grade at the end of the bathhouse building adjacent to the park. These rooms have deteriorated due to chemical fumes and spills. The Aquatic Design Group, Inc. Hiddleson Pool Page 4 of 26

activity pool mechanical equipment is stored in a small building at the opposite end of the pool deck from the bathhouse. Both the activity pool equipment and activity pool chemicals are stored in the same room. This has contributed to the deterioration of the activity pool equipment.

D. PROGRAMMING Aquatic Design Group met with city staff to identify the current and desired programs offered at the Hiddleson Pool. The City of Woodland also operates a separate aquatic facility which features a 50-meter swimming pool and a play pool adjacent to the high school. The Hiddleson swimming pools were not open for use during our visit. The pool water had been emptied from both pools and the mechanical equipment was not operating. We did not have operating budget data for the Hiddleson facility. The California industry standard for a rectilinear pool averages approximately 40-50% annual cost recovery for recreational type facilities. The existing configuration of the two Hiddleson pools does not allow for swim team use and rentals since they do not provide 25-yard long swim lanes for lap swimming or swim meet use. The facility also lacks recreational amenities typically found in modern aquatic centers. Given these conditions, the programs that can be supported by the existing pools are limited. If the swimming pool were to be re-opened the City should consider shortening the pool to a 75-foot length to support programming. The Woodland staff identified the following potential programs: Recreation Swim Youth and Adult Swim Lessons, beginner to advanced Company Rentals Private Rentals Aqua Aerobics Junior Lifeguard Certification Lifeguard Certification Fitness Classes Swim Team Use EXHIBIT 5: POOL DECK LAYOUT Aquatic Design Group, Inc. Hiddleson Pool Page 6 of 26

As stated earlier, municipal swimming pools in California that are rectilinear in configuration typically generate about a 40-50% annual operating cost recovery. As a pool s recreation features and capabilities are increased, including items such as slides and interactive water features, these operating cost recoveries can be increased as much as 70% to 100%. The increase in cost recovery can be directly attributed to an increase in programs offered at an aquatic facility as well as the number of repeat visits by the patrons. There are certain basic services such as recreation swim and swim lessons that a community typically provides at minimal subsidies. As the programs offered become more individualized, fees increase to market values. These enhanced programs can include master swim teams, water aerobics, party rentals, and others. As fee based programming is added to a facility the potential to recover operating expenses increases. Exhibit 6 shows the relationship between subsidized community benefit programming and individualized programming. Exhibit 7 shows typical revenue sources from a municipal aquatic center, and Exhibit 8 shows typical operating costs for the average aquatic center in California. EXHIBIT 6: FEE STRUCTURE THEORY These individualized programs can: Create value for the services and facilities Allow rationing of high demand services and facilities Reserve funding for other necessary programs Aquatic Design Group, Inc.

EXHIBIT 9: EXAMPLES OF OPERATING COST RECOVERY $700,000 $600,000 $500,000 $400,000 $300,000 Revenue Expense Net Profit $200,000 $100,000 $0 Central Park Aquatics Center* Denton Aquatic Center Doolittle Community Center Johnston Aquatic Center* Exhibit 8 shows the operating cost recovery of four sample regional aquatic centers. The Central Park and Johnston Centers have indoor and outdoor pools. In many cases the new trend for aquatic centers is shared facilities that can be used by City Park and Recreation Districts as well as local high schools, YMCA, or other entities. The more competition programming is brought into a facility the less likely that the facility will recover its annual operating expenses. The facilities shown in Exhibit 9 represent regional type aquatic centers that focus primarily on recreational programs. These facilities all have pool slides, interactive water play features and other amenities to make them more of a destination type facility. To achieve a positive operating cost recovery, these facilities cannot operate as old Municipal pools used to, as drop-off facilities. To achieve a positive cost recovery these facilities must include revenues from concessions and other program draws, and are also must be in a position to charge market level pricing for admissions and other programs. Exhibit 10 shows an industry average for cost recovery for the different types of modern aquatic centers. The Hiddleson Pool does not fit precisely into any of these categories as the Plunge does not provide Aquatic Design Group, Inc. Hiddleson Pool Page 9 of 26

competitive venues, nor does it offer modern recreation programs such as slides and interactive water playgrounds. EXHIBIT 10: COST RECOVERY FOR POOL TYPES Recreation pools typically offer interactive play features such as spray features and slides. These types of facilities will also offer shade areas and concessions. With these types of features an operator can expect to draw patrons on repeated visits. When these visits are made by families rather than children that are dropped off, the potential for concession revenues are greatly increased. All of these features can contribute to the annual operating cost recovery potential for a facility. More details of interactive play features such as wet-play areas, interactive wading pools and pool slides will be included in the enhancement portion of this report. The following is a list of revenue opportunities that may be achieved from a comprehensive aquatics center: Programming Rentals and Parties Merchandising Concessions Programming Marketing Partnerships Sponsorships Aquatic Design Group, Inc.

E. OPERATIONAL ISSUES Aquatic Design Group met with city staff to determine the current means of operation of the facility and to target issues and desired changes to the Hiddleson Pool. In general, the facility was found to be in typical shape for a facility of its age and nature. A large portion of the buildings, pools, pool mechanical equipment and mechanical space is in need of repair and replacement and is of concern to staff. The staff is most concerned with identifying options to provide better services in the most efficient and economical way if the facility is to be reopened. City staff identified the following issues for the operation of the facility: Labor required and labor expense Chemical usage and expense Utility usage and expense Sustainable features that are effective for constant operation Ways to increase the safety of the operation The following matrix is a summary of the pool mechanical conditions found and identified by the Aquatic Design Group staff: ITEM SWIMMING POOL ACTIVITY POOL Hair & Lint Strainer Poor Average Recirculation Pump/Motor Average Poor Filter System Good Poor Heater Poor Poor Chemical Controller Average Average Plumbing Valves Poor Poor Chlorine Pump Average Poor Chlorine Storage Poor Poor ph Feed Average Poor ph Storage Poor Poor Electrical Average Poor Aquatic Design Group, Inc.

F. POOL ISSUES The following is a list of the facility issues noted during our review. We have assigned a priority rating for each item rated 1-3. I priority rating of 1 is an item that must be addressed before the facility is reopened. A priority rating of 2 is an item that is a concern for the long term operation of the facility. A priority item of 3 is an item that should be addressed, but may be repaired for short-term use, until it can be permanently remedied. There are several items with priority 2 ratings that the Yolo County Health Department may require renovation prior to the re-opening of the facility. ITEM DESCRIPTION PRIORITY 1 The facility lacks ADA access to the entrance of the building. 1 2 The changing rooms do not have ADA access. 1 3 The bathhouse bathroom fixtures are not ADA compliant. 1 4 The facility does not have the minimum number of bathroom fixtures to meet 1 California Health Code and California Building Code. 5 Bathroom floor tile is worn and is considered a slip and fall hazard. 2 6 Portions of the building are deteriorating as is evident by wood members 3 rotting and cracks in the block walls. 7 The chemical rooms are deteriorating with the doors and frames rusted out. 2 8 The swimming pool perimeter fence does not meet the minimum standards of 1 the California Building Code as a non-climbable barrier. 9 The swimming pool concrete decking is cracking and has differential 1 separations that are considered slip and fall hazards. 10 The swimming pool decking lacks safety markers as required by code. 1 11 The swimming pool has stainless steel gutters which do not meet the 2 minimum requirements of the California Health Department Code. 12 The swimming pool lacks floor inlets as required by California Health 2 Department Code to provide distribution of filtered and chemically treated water throughout the pool. 13 The swimming pool lacks ADA compliant accessibility. Given the size of the 1 pool, 304-perimeter feet the pool requires a minimum of two means of ADA accessibility. 14 The swimming pool main drains are not VGB and California AB1020 1 compliant as anti-entrapment devices. 15 The swimming pool has an expansion joint that is failing. 3 16 The swimming pool is 100 long which does not support USA Swimming 3 standards or the required lengths for the National Federation of State High Schools (CIF). 17 The swimming pool plaster and tile finish is delaminating and needs 1 replacement. 18 The swimming pool underwater lights need to be replaced. 2 19 The swimming pool lacks water line depth and safety markers as required by 1 code. 20 The swimming pool heaters are failing and need to be replaced. 3 21 The activity pool underwater lights are not installed in accordance with the 1 California Electric Code. 22 The activity pool main drain is not VGB and California AB1020 compliant as a 1 non-entrapment suction device. 23 The activity pool plaster finish is delaminating and needs to be replaced. 1 Aquatic Design Group, Inc. Hiddleson Pool Page 12 of 26

ITEM DESCRIPTION PRIORITY 24 The activity pool lacks pool stairs for access as required by California Health 2 Code. 25 The activity pool lacks ADA compliant accessibility. 1 26 The activity pool mechanical equipment is deteriorated and needs replacing. 3 The following is a description of each issue found with a preliminary opinion of probable cost to remedy the issue. These individual estimates do not include full project soft costs, which will be shown in the proforma estimate in section G this report. 1. The facility lacks ADA access to the entrance of the building. There is limited parking adjacent to the building and street parking. The path of travel from the parking or the side walk must then travel up stairs to gain access to the building. The front entry to the building is the location that money is taken and admission is allowed for all patrons to the facility. An ADA compliant path of travel should be provided to the building. Estimate Cost: $85,000.00 2. The changing rooms do not have ADA access. The facilities accessible from the front entrance are not ADA compliant. Separate bathrooms have been provided on the pool deck which, have ADA fixtures, however this does not provide inclusive and equal access for everyone to both changing areas and bathroom fixtures. ADA compliant changing areas should be provided. This will require a complete renovation of these spaces. Estimate Cost: $722,500.00 3. The bathhouse bathroom fixtures are not ADA compliant. The bathrooms in the main building accessible from the front lobby do not have ADA complaint fixtures or paths of travel. Separate bathrooms have been provided on the pool deck which have ADA fixtures; however this does not provide inclusive and equal access for all patrons from the front lobby. ADA compliant bathroom fixtures should be provided. Estimate Cost: Included in item 2 above EXHIBIT 11: FRONT ENTRY Aquatic Design Group, Inc. Hiddleson Pool Page 13 of 26

4. The facility does not have the minimum number of bathroom fixtures to meet California Health Code and California Building Code. As shown in exhibit 3 above the facility lacks the minimum number of bathrooms fixtures as required by California Title 24 State Administrative Code, Chapter 31B. The bathroom changing rooms should be reconfigured to meet or exceed the minimum number of fixtures required by code. Estimate Cost: Included in item 2 above 5. Bathroom floor tile is worn and is considered a slip and fall hazard. The tile floors in the bathrooms and changing areas are slick and pose potential slip and fall hazards. This tile should be replaced when these areas are renovated to provide ADA access and the minimum number of fixtures as required by code. Estimate Cost: Included in item 2 above 6. Portions of the building are deteriorating as is evident by wood members rotting and cracks in the block walls. If the City intends to invest capital into this facility to operate it for oncoming years then the building deterioration should be addressed. It would not be prudent to invest large sums of money into the facility only to have closures or worse due to deteriorating materials and finishes. Our study does not include destructive testing to determine the structural and seismic viability of the facility. Estimate Cost: $244,000.00 EXHIBIT 12: CHEMICAL ROOMS 7. The chemical rooms are deteriorating with the doors and frames rusted out. The chemicals for the swimming pool are stored in rooms on the outside of the building facing the open park area. These rooms, their doors and frames are severely corroded due to exposure to chemicals and the elements. The chemical rooms and room hardware should be replaced or repaired to serve future use of the facility. Estimate Cost: Included in item 6 above Aquatic Design Group, Inc. Hiddleson Pool Page 14 of 26

8. The swimming pool perimeter fence does not meet the minimum standards of the California Building Code as a non-climbable barrier. The pool is enclosed with a combination of the bathhouse, block walls and chain-link fencing. California Administrative Code Title 24, Chapter 31B requires that these barriers meet minimum standards to prevent children from climbing or otherwise gaining unsupervised access to the swimming pools and the potential health and safety risk this may pose. For example, a chain-link fence must have openings not larger than 1.75 when measured on the diagonal. Also fences must not have horizontal members which could make a fence or barrier climbable. The existing walls and fences should be modified or replaced to comply with code. Estimate Cost: $24,000.00 9. The swimming pool concrete decking is cracking and has differential separations that are considered slip and fall hazards. The concrete pool decking is cracked, spalling and has differential movement creating potential slip and fall hazards. In addition, these deficiencies can also prevent ADA access to the pools. Given the failures of the existing deck a simple top-coat finish will not resolve the issues. In addition deck coatings have a very limited life span of 1-5 years before they must be removed and replaced. We recommend the complete removal and replacement of the pool deck concrete to provide a sustainable and long lasting deck if the pool is to be put back into service. Estimate Cost: $375,000.00 EXHIBIT 13: POOL DECK 10. The swimming pool decking lacks safety markers as required by code. The deck depth markers and safety signs as required by CALIFORNIA STATE ADMINISTRATIVE CODE, TITLE 24, CHAPTER 31B are not installed. The must be installed prior to the pool being put back into service. Estimate Cost: Included in item 9 above Aquatic Design Group, Inc. Hiddleson Pool Page 15 of 26

11. The swimming pool has stainless steel gutters which do not meet the minimum requirements of the California Health Department Code. The pool was previously renovated and the original pool scum gutter was replaced with a stainless steel gutter around the entire perimeter of the swimming pool. This gutter is failing allowing pool water to leak to the surrounding soil. In addition, filtered and chlorinated pool water is distributed throughout the pool via slots in the bottom of the gutter. This distribution method does not meet the standards of the CALIFORNIA STATE ADMINISTRATIVE CODE, TITLE 24, CHAPTER 31B. The stainless steel gutter should be removed and replaced. Estimate Cost: $121,600.00 12. The swimming pool lacks floor inlets as required by California Health Department Code to provide distribution of filtered and chemically treated water throughout the pool. As noted in item 11 above, the filtered and chlorinated water is currently configured to distribute throughout the pool via slots in the gutter near the water surface. CALIFORNIA STATE ADMINISTRATIVE CODE, TITLE 24, CHAPTER 31B requires that the water and chemicals be evenly distributed via floor inlets in the bottom of the pool. To achieve this distribution piping will have to be installed under the floor of the pool, which will require saw-cutting, removing and replacing a large portion of the pool floor. Estimate Cost: $58,000.00 13. The swimming pool lacks ADA compliant accessibility. The swimming pool has 304- perimeter feet of pool wall which requires a minimum of two means of ADA accessibility. Federal regulations requires all public swimming pools that have 300 perimeter feet of pool wall or larger to have a minimum of two means of ADA access into the pool. One of these two means of access must be an approved primary means of access, which is an ADA lift or a ramp. A secondary means or another primary means of ADA access may be used for the second means in the swimming pool. Transfer stairs are an approved secondary means of ADA access into the pool and can provide universal benefit to all patrons that cannot or wish not make a vertical climb up pool wall steps. Transfer stairs should be added to the pool. Estimate Cost: $36,000.00 EXHIBIT 14: SWIMMING POOL Aquatic Design Group, Inc. Hiddleson Pool Page 16 of 26

14. The swimming pool main drains are not VGB and California AB1020 compliant as antientrapment devices. Both the Federal VGB law and California AB1020 require all public swimming pools to have a minimum of two main drains that are a minimum of 3 apart, hydraulically balanced and equipped with drain grates and fittings that are certified by an accredited national testing agency or the pools shall not be allowed to open for use. The swimming pool main drains are not compliant and must be replaced before the pool can open. Estimate Cost: $40,000.00 15. The swimming pool has an expansion joint that is failing. The swimming pool was designed and constructed using an expansion joint between two sections of the pool. This joint is failing which allows large amounts of water to leak from the pool and can pose a health and safety hazard. Furthermore, this joint cannot be made to work with the installed stainless steel gutter. The expansion joint must be repaired or replaced before the pool is put back into service. Estimate Cost: $14,000.00 16. The swimming pool is 100 long which does not support USA Swimming standards or the required lengths for the National Federation of State High Schools (CIF). The swimming pool is 100-feet long, which does not meet the standards for any organized swim groups. If the City wishes to rent the pool to swim teams or other groups for training or swim meets the pool should be shortened to a 25-yard course to meet their needs. This is especially true given the extent of the other modifications that must be conducted to the pool before it can reopen. Estimate Cost: See new pool option 17. The swimming pool plaster and tile finish is delaminating and needs replacement. The swimming pool plaster and tile finish is intended to provide the water proof finish for the pool and to create a finish that will not harbor pathogens or sharp edges that can pose health and safety concerns. The existing swimming pool plaster is failing and must be replaced before the pool can reopen. Estimate Cost: $167,000.00 EXHIBIT 15: SWIMMING POOL EXPANSION JOINT Aquatic Design Group, Inc. Hiddleson Pool Page 17 of 26

18. The swimming pool underwater lights need to be replaced. Assuming that the City intends to operate the pool at times other than direct sunlight, then the pool must have underwater lighting as required by CALIFORNIA STATE ADMINISTRATIVE CODE, TITLE 24, CHAPTER 31B. The existing underwater pool lights are reported by staff as non-operational and should be replaced. In addition, new LED underwater pool lights are now available which can reduce the electrical draw by 86% and require far less staff maintenance and labor. Estimate Cost: $30,000.00 19. The swimming pool lacks water line depth and safety markers as required by code. CALIFORNIA STATE ADMINISTRATIVE CODE, TITLE 24, CHAPTER 31B requires that a public swimming pool have a contrasting pool floor stripe, rope hooks and a safety line to be installed at the 4-6 water depth point of pool to denote the shallow from the deep areas of the swimming pool. These items should be added when the pool is renovated before it reopens. Estimate Cost: Included in item 17 above 20. The swimming pool heaters are failing and need to be replaced. The City staff reports that the swimming pool heaters have failed and will not be able to maintain the pool water temperature if the pool is reopened. New heaters that meet the Air Quality Control Board Standards for gas fired appliances should be installed. Estimate Cost: $14,000.00 21. The activity pool underwater lights are not installed in accordance with the California Electric Code. CALIFORNIA STATE ADMINISTRATIVE CODE, TITLE 24, CHAPTER 31B and the California Electric Code Article 680, requires that underwater pool lights be installed with the top of the light not less than 18 below water level. The existing lights are not installed to this standard and need to be replaced or removed before the pool can open. Estimate Cost: $8,000.00 EXHIBIT 16: SWIMMING POOL Aquatic Design Group, Inc. Hiddleson Pool Page 18 of 26

22. The activity pool main drain is not VGB and California AB1020 compliant as a nonentrapment suction device. Both the Federal VGB law and California AB1020 require all public swimming pools to have a minimum of two main drains that are a minimum of 3 apart, hydraulically balanced and equipped with drain grates and fittings that are certified by an accredited national testing agency or the pools shall not be allowed to open for use. The activity pool main drains are not compliant and must be replaced before the pool can open. Estimate Cost: $28,000.00 23. The activity pool plaster finish is delaminating and needs to be replaced. The activity pool plaster and tile finish is intended to provide the water proof finish for the pool and to create a finish that will not harbor pathogens or sharp edges that can pose health and safety concerns. The existing activity pool plaster is failing and must be replaced before the pool can reopen. Estimate Cost: $32,000.00 24. The activity pool lacks pool stairs for access as required by California Health Code. California Building Code, Chapter 31B, requires that all public swimming pools have stairs to allow patrons to access or exit the pool. The activity pool lacks such stairs. These stairs will serve program for young children in swim lessons or for families with small children a place to recreate in the pool. Pool stairs should be added to the pool. Estimate Cost: $26,000.00 25. The activity pool lacks ADA compliant accessibility. Federal law requires that all public swimming pools have a primary means of ADA access, which is an ADA compliant lift or ramp. This ADA access must be installed and ready for use anytime the pool is open for use. An ADA lift should be added to the activity pool. Estimate Cost: $8,000.00 26. The activity pool mechanical equipment is deteriorated and needs replacing. The activity pool mechanical equipment and chemical storage are currently in the same space. As a result all of this equipment is severely corroded and in need of replacement before the activity pool is re-opened. Estimate Cost: $33,000.00 EXHIBIT 17: SWIMMING POOL Aquatic Design Group, Inc.

The renovation estimate above is to bring the existing facility and pools to like new and compliant with current standards. However, it does not reconfigure the pools to serve the desired program. For example there pools will not have 25-yard swim lanes to serve a swim team and lap swimmers. Also the pools do not provide recreation programs to provide a maximum annual operating cost recovery potential. Given the extent of the renovation budget the City may consider replacing the existing pools with new modern pools that can better serve the desired programs. One option is to replace the two pools with a single multi-purpose pool as shown below. EXHIBIT 19: 5,000 SQ.FT. MULTI-PURPOSE POOL Aquatic Design Group, Inc. Hiddleson Pool Page 21 of 26

In lieu of a single multi-purpose swimming pool the City could consider the removal of the two existing pools is replacing them with two modern pools. The first pool can be a 6-lane by 25-yard swimming pool that can serve the needs of a swim team for practice and small swim meets as well as lap and recreation swimmers. A second wading pool (maximum 18 water depth) with interactive play equipment or a sprayground could be built. An advantage to this option is that if the swimming pool is operated year round the wading pool does not have to be maintained year round when children are back in school, which can reduce operating expenses versus a single multi-purpose pool. The following is an example of a modern two pool community pool complex. EXHIBIT 21: 2 POOL COMPLEX Aquatic Design Group, Inc. Hiddleson Pool Page 23 of 26

Certain areas are worn and tired and in need of renovation. The pool structure is assumed to be sound as noted previously in this report without any destructive testing to confirm. With the correction of code violations and the suggested improvements the pool will and can be restored to its original condition. It must be kept in mind that even though the pool components meet current standards, the comparative cost to repair versus replace the pool and the risk associated with renovation work should be carefully evaluated. As such, a decision should be made as to whether the capital expenditure provides an acceptable return in a cost benefit analysis of any renovation versus replacement.
