David R. Johnson Memorial Pool GENERAL Architectural Assessment Based on drawings dated 11/06/89 as provided by the Owner, the buildings are constructed of slab-on grade, concrete masonry units and wood framing with plywood siding, and roof construction consisting of wood joists and glu-lam beams. Exterior envelopes consists of single pane glazing, painted concrete unit masonry and painted plywood siding. In general the building is in good condition with the exceptions noted herein, and most specifically: Conditions that are not compliant with current requirements of the California Uniform Building Code and/or the Americans with Disabilities Act (Non-Compliant). Exterior glazing relative to insulation value Structural (roof to wall anchorage) Building address signage and code required signage missing Structural Assessment The Johnson pool complex has an outdoor pool and three buildings associated with it. The buildings consist of a main building, a pool equipment building and a storage building. No drawings of the original construction were provided but I understand that the original project was built approx. 1960. A set of repair/remodel drawings was prepared by Piches Architects in 1989 on the main building. All of the buildings generally have wood framed roofs, CMU walls and exposed concrete slabs on grade. All of the exterior walls and roof fascias are painted. The building structure of the approx. 3,000 sq. ft. main building is of light wood framed roofs and CMU exterior walls with some wood framed walls. The roof structure consists of plywood over 2x6 rafters @ 24 cc spanning to 4 1/4 x 14 5/8 glu-lam beams or CMU bearing walls. Much of the roof structure is exposed on the interior and many of the glu-lam beams that extend over the walls are exposed to the exterior. Many of these glu-lam beams extend to form 8-0 long overhangs. The center portion of the main building has exterior plywood siding (T1-11) with the two wings (locker area) having exposed painted CMU. The building structure of the approx. 10 x 36 pool equipment building consists of 2x6 rafters @ 24 cc spanning to 8 CMU exterior walls. The roof structure is exposed on the interior. The building structure of the 260 sq. ft. triangular shaped storage building consists of 2x6 rafters @ 24 cc spanning to 8 CMU exterior walls. The roof structure is exposed on the interior. Observations and Recommendations The CMU walls are in generally very good condition as they have very few small cracks and no other obvious signs of distress. The concrete slab on grade appeared to be in good condition with a few small cracks noted. Page 4 Y:\153500.00\Reports - Studies\Facility Assessment\Johnson Pool Assessment.doc
David R. Johnson Memorial Pool The exterior walls with plywood siding do have several areas where the siding shows signs of dry-rot. These areas are generally near the finish grade line at the bottom of the siding where water has wicked up and created the condition. Also, many of the exposed ends of the glu-lam beams on the main building are showing signs of dry-rot and a repair of these beam ends should be done. No signs of dry-rot were noted on the pool equipment or storage buildings. An issue that is normal for the age of the building is that none of these CMU walls have out of plane wall ties. Newer codes require that these walls be anchored to the roof and we would recommend that the wall anchors be added. HVAC Assessment In general, the following are based on site observation with City maintenance on 10/14/2015: There are two roof mounted evaporative coolers on the roof. The units are reaching their life expectancy. At a minimum recommend replacing the pads and clean the units internally. The ductwork is routed to the offices and needs to be cleaned. The controls are wall switch serving each units. Natural ventilation is used for the restrooms. Plumbing Assessment In general, the following are based on site observation with City maintenance on 10/14/2015: The plumbing fixtures in this facility were replaced a few years ago and generally are in good working condition. The lavatory faucets are electronic type and are in working condition. The showers are stainless steel metered faucets. Some of the controls are missing. The water closets are wall mounted with manual flush valves. The fixtures appear to be the original units not the low flow type. There is an outdoor emergency shower next to the pool equipment room. The unit is in good condition. There is an outdoor boiler for the pool heating system which is in good working condition. The roof drainage system needs to be checked for proper drainage. Electrical Assessment In general, the following are based on site observation with City maintenance on 10/14/2015: The three buildings consist of a main building, a pool equipment building and a storage building. There are no known electrical drawings available or were provided. City maintenance indicated no known electrical deficiency or system malfunction. The facility s 120/240 volt, 3 phase, 200 amp electrical service meter/main and main panel are located inside the storage building. Though they exceeded their life expectancy, they remain adequate and functional for the current facility s electrical use. o As required by electrical code and OSHA, move and clear all equipment and/or items to maintain minimum of 3-0 clearance at the front of all electrical panels. Page 5 Y:\153500.00\Reports - Studies\Facility Assessment\Johnson Pool Assessment.doc
David R. Johnson Memorial Pool A 100 amp panel is located inside the main building. Though the panel exceeded its life expectancy, it remains adequate and functional for the current building s electrical use. A 125 amp panel is located inside the pool equipment building. Though the panel exceeded its life expectancy, it remains adequate and functional for the current building s electrical use. All buildings interior T8 fluorescent lighting fixtures and manual switching are old, they are adequate and functional for each current building s use. o Recommend to clean all light fixture lens and re-lamp. Replace any malfunctioning light fixtures and/or broken lens. All building s interior power outlets are adequate and functional for each current building s use. All exterior building s wall mounted light fixtures are compact fluorescent and are controlled by the facility s time clock. Though the light fixtures are old, they are adequate and functional for each current building s use. o Recommend to clean all light fixture lens and re-lamp. Replace any malfunction light fixtures and/or broken lens. The swimming pool pole lights around the perimeter of the pool consist of multiple clu sters of PAR type flood lamp light fixtures at each pole. Though the pole lights are old and obsolete, they are adequate and functional for current swimming pool intend use. o Recommend to clean all light fixture lens and re-lamp. Replace any malfunction light fixtures and/or broken lens. No intrusion alarm system observed for the facility. o Recommend new intrusion alarm system for security of the premise consist, at the minimum, indoor motion sensors and door contacts at each exterior doors.

Pool Assessment 100 D Street, Roseville, CA INTRODUCTION Arch Pac representatives visited your pool in Roseville, CA on October 14, 2015 to observe its existing condition. Original construction documentation was not available for review and could prove valuable if existing. Encountered was an approximate 40-0 by 100-0 pool with skimmers and a deep end that was approximately 9-0 deep and a 1-0 deep shallow end. It appeared as if a wading pool was incorporated into a recreational swimming pool which is typically a Code taboo based on the fact that wading pools have different recirculation requirements. The pool area facility featured a bathhouse on the east end and a picnic area on the west end with the pool mechanical room on the southeast side. Vernon Avenue cuts diagonally across the top of the site between the railroad switching yard and the pool so it is located just southwest of the old downtown area. In conversation with the maintenance and operation staff it was revealed that the pool was constructed in the 1930s by the railroad company and was once filled with ice water from a local icehouse (Pacific Fruit Express the largest ice house in the world at that time erected in 1913 demolished in 1974) to be utilized by Southern Pacific railroad employees. The pool required emptying daily, as no water was ever recirculated or treated. Later the pool was modified so as to provide recirculation and filtration as this is certainly not the case today. It has been modified on several occasions over its life as the skimmers, filtration, piping, heater, recirculation pump and bathhouse all Page 33
Are showing signs of significant maintenance, modification and repair over the years. There is a bench for seating along the north side of the pool and couple of different types of fences from wood, CMU to chain link. The pool mechanical room is below water level on the southeast side and the pool. As can be seen from the site plan presented above, the pool s long direction cuts diagonally across the site, parallel to Vernon Avenue from southwest to northeast. Service access is on the south side of the pool with a ramp down to the mechanical room from the pool deck and storage room. City Staff stated that a couple of decades ago that the pool was utilized competitively on the high school level by placing a bulkhead at 75-0 from the deep end. This bulkhead no longer exists today, the bulkhead deck stanchions are however still there. Staff states that the pool is only utilized two months a year. View of pool towards the southwest from entry at the northeast corner This evaluation compares the pools existing condition with that required by the California Building Code (2013 edition), appropriate Title 24 amendments along with County Health Department regulations and pertinent sections of the UMC, UFC & NEC (National - electrical, mechanical & fire) Codes. Deficiencies noted herein and proposed remedies are listed at the end as potential Recommendations. A cost to remove deficiencies and implement recommendations is established, in spreadsheet format, also at the end of this evaluation. The goal is to establish a budget and allow for informed decisions as to the best course of action; modify, modernize, replace and/or repair the facility. Page 34
The goal will be to bring the facility up to Code and to implement a plan to extend the life and utility of the facility, decrease the cost of maintenance & operations and ensure public safety. The cost estimates (although preliminary) are to facilitate informed decisions, establish budgets, consider and plan alternatives for the future. Also to be considered are removal and replacement options for the pool. Some alternatives will also be given that may create alternative possibilities capitalizing on different opportunities such as water play features and other alternative uses. View of the pools southwest end (deep end) with a tube style plastic slide. note main drain Recommendations are prioritized, where possible. Picking and choosing items from various options based on desirability may not be an alternative as the County Health Department may defeat this process by requiring any work proposed be linked with other items as an all or nothing proposition. On more than one occasion requirements of modernization have been implemented only with the provision that if any work was to be done, that all non-conforming conditions be corrected. Multiple jurisdictions, placing differing degrees of importance on certain items, make it difficult to orchestrate a budget based on the inability to pick and choose among the various proposed modifications.

Note: that the code or an interpretation or paraphrase of same, is presented herein in red, while commentary is presented in black. Highlighted text are referencing recommendations. Bathhouse and main entry along THE SITE: The pool complex was constructed in the 1930 s which makes it approximately 8 decades old at the time of our visit. The bathhouse facility has a serrated form along D street. It is a concrete masonry building with a wood framed roof. ADA access from street side curb parking to pool will need to be addressed within the limitations of an existing building and pool complex, constructed prior to the imposition of ADA (1973). Access will need to be addressed. Additional accessible exits should be provided and are required under today s code, so additional accessible exit locations will be required. Each exit should have a self-latching and self-closing door with panic hardware for exiting without requirement of a key or special tool and be ADA accessible. Sloping walks or ramps to exit gates are also too steep, cross slope too great and without handrails. Page 36
Sodium Hypochlorite storage room door (east end of pool mechanical room) The pool mechanical equipment room is on the south side of the complex and pool equipment is contained within and around the pool mechanical room. Access for chemical delivery is at the east end of the pool mechanical room for sodium hypochlorite and hydrochloric acid is stored in the mechanical room itself. The pool and deck are constructed of reinforced cast-in-place concrete. The mechanical room walls are of CMU. Chemical Storage vessels should be stored safely and separately with seismic restraints and in dual containment vessels, appropriately labeled with proper signage. Page 37
View of pools mechanical room with rapid sand filters. & existing pump and strainer View of both entries from gates on south side of complex neither is ADA accessible ACCESS: Swimming pools and their appurtenances shall be in compliance with the requirements of the state architect regarding access to public accommodations by physically handicapped persons. (ADA) ADA access to the pool area and bathrooms needs to be addressed, exiting should be marked with self-illuminating signs. Doors are self-closing and self-latching as required by Code and should be marked as exit paths with panic hardware and accessible hardware. Page 38
Gates on both south side entries of chain link, without hardware and inaccessible POOL STRUCTURE The pool shall be designed and durably built, watertight, and able to withstand anticipated stresses under both full and empty conditions, taking into consideration climatic effect, geological conditions, integration of the pool with other structures. Pool is constructed of cast-in-place concrete and appears level and capable of withstanding the pressures of ground water and soil as it has done so for almost eight decades. The pool is ageing with significant finish discoloration and other finish depreciation the fiberglass is worn enough to reveal the glass shards typically embedded in the gel coat. The application of fiberglass was probably placed over a failing plaster application. It is probable that major modifications will require that pool tile and deck tile be removed and pool finishes replaced. The depth of the deep end of the pool is 9-0 which is deep considering that there is no diving apparatus, it was replaced with the slides pictured previously. For safety reasons, it is not wise to have drop patrons into the deep end of the pool. The main drain is an anti-suction entrapment grate, but there I only a single drain sump so it would not be compliant with Virginia Graeme Baker Act. Typical pool vessel coping and 4-6 line paint on fiberglass and water proofer needs to be replaced. Page 39
Finish - the finished pool shell shall be lined with a smooth waterproof interior finish that will withstand repeated brushing, scrubbing and cleaning procedures. The interior pool finish shall completely line the pool to the tile lines, or coping. The pool fiberglass and plaster with tile over cast-in-place concrete is depicted in the photo above, it appears to be in a failing condition and requires replacement soon. The water line tile and freeboard are also tiled with a single ceramic 6x6 glazed tile. We were informed by City Staff that there is an approximate water leak of 10,000 gallons per week that requires repair. A finish that can also withstand emptying of the pool during the off season may also be desirable. Water line tile and depreciated fiberglass cover finish Pool Finish Color. The finish color shall be white except for: 1. Lane and other required pool markings, such as the 4-6 line and step coping 2. Handholds and/or waterline tile The pool finishes were: 1. Fiberglass over plaster with waterline tile 2. Hand holds (safety grabs) were of bull-nosed and precast concrete coping stones as this is not a continuous gutter style pool Page 40
Shallow end of pool at 1-0 and deep end and 9-0 4-6 line while faded is visible. POOL DIMENSION AND SLOPE. The dimensions and slopes of a pool shall be no greater than 1/10 at the shallow end to the 4-6 line and thence a maximum slope of 1/3 to the deepest portion of the pool or main drain The shape of the pool is a rectangle, and was a 40-0 by 100-0 with a wading pool (16 x 18 feet) at the shallow end. The pool depth is 1-0 to approximately 9-0 deep. The slopes in the shallow area is less is not greater than 1/12. The Code was modified in the 1960 s to move the break between deep and shallow ends of the pool from 5-0 to 4-6 so at the 5-0 depth the slope changes to not steeper than 1/3. This pool complies. Page 41
Change in slope at the 4-6 to 5-0 foot line. Single main drain in deep end of pool DRAINABLE, the pool shall be completely drainable through a main drain that shall be located at the deepest point in the pool. The pool has a single main drain located in the deep end of the pool. The pool is drainable via that main drain. VGB compliant main drains with associated piping will need to be added to pool repair. DIMENSIONAL TOLERANCE, the pool construction tolerance shall not exceed 2 inches except with the tolerance of the water level within the skimmer. Pool has a skimmer style pool and vessel appears to be level and within the tolerance all the way around. If renovated it is suggested that the skimmers be replaced as they are not constructed correctly. There is a latent defect in connecting them to the deck instead of the pool bond beam. As the deck expands and contracts throughout year round temperature swings the PVC typically cracks causing the pool to leak. Piping for the pool s recirculation system should also be replaced because this is always examined as concrete decks are removed and replaced. Make-up water valve and Skimmer and 5-0 line - (old Code allowed break line to be at 5-0 ) Page 42
SLOPE BREAK SHALLOW TO DEEP WATER. When a pool has a change in bottom slope from shallow to deep water; flush-mounted devices for fastening a safety rope and buoys across the pool shall be installed where the water depth is 4-6 feet. The pool has that slope break at 5-0" or in the approximate center of the pool then more steeply to approximately 9-0 at the deep end of the pool. DEPTH MARKING LINE. There shall be installed a straight line, 4 inches wide, of contrasting color across the bottom of the pool where the water depth is 4 1/2 feet. (5-0 in earlier Codes) The pool has a painted 5-0 line with rope anchors on the sides of the pool at the slope break for a buoy line that separates shallow from deep end. Existence of buoy line or its use could not be verified. Painted on depth markers to not indicate FT & IN as required. DEPTH MARKERS, shall be clearly marked at the following locations: 1. Maximum depth 2. Minimum depth 3. Each end 4. At the break in the bottom slope between the shallow and deep portions of the pool 5. On the perimeter of the pool at distances not to exceed 25 feet Vertical depth markers in water line tile were faded and illegible and horizontal depth markers painted on and could use another coat of paint. They also do not have correct annotation in feet and inches. Page 43
No Diving warning marker above no running markers not found. DEPTH MARKERS, shall be located on the vertical pool walls at each end and side of the pool at or above the water level. If a pool exceeds 20 feet in width, additional markers, shall be located on the edge of the deck next to the pool. The depth markers shall be located so as to be clearly visible to bathers in the pool. Markers shall be positioned to indicate the water depth accurate to the nearest 6 inches. Warning markers were only in-place in the shallow end as No Diving markers. No Running markers not found. They should be placed no more than 3-0 from the pool edge. STEPS, RECESSED STEPS, LADDERS AND RECESSED STAIRS A means of entry and exit to and from the pool shall consist of steps, recessed steps, ladders or stairs, or a combination of them. One means of entry and exit shall be provided in the shallowest portion of a pool if the vertical distance from the bottom of the pool to the deck is over 2 feet. A second means of entry and exit shall be provided in the deep portion of a pool having a depth greater than 41/2 feet. Where the width of the pool exceeds 30 feet, such means of entry and exit shall be provided at each side, not more than 100 feet apart. The pool has removable ladders at each side some are still present while others have only deck Page 44
stanchions. The pool is too shallow for steps in the shallow end. A handrail is advised but not required. Typical safety grab, hand hold of precast coping note deck is falling away causing tripping hazard. HANDHOLDS, shall be provided with handholds around the entire perimeter installed not greater than 9 inches above the waterline. A bull-nosed coping or material equivalent in strength and durability, with rounded, slip-resistant edges shall be provided. The handhold shall not exceed 2 inches or be less than 1 inch and shall not exceed 2 1/2 inches in thickness. Pool is in compliance as a precast concrete coping is placed continuously around the pool with a bullnose edge to be utilized as a handhold placed about six inches above water level. Page 45
Deck condition note repairs and slope deck drops away from pool at about 1/20 cross slope POOL DECKS, a minimum continuous and unobstructed 4-foot-wide slip-resistant nonabrasive deck area of concrete or like material shall be provided flush with the top of the pool shell wall extending completely around the pool. The deck width shall be measured from the poolside edge of the coping lip. The width of deck is greater than that required, unobstructed, slip-resistant and nonabrasive. Decks are in poor condition and the slope is too great to meet the requirements of a maximum of ¼ per foot cross slope as imposed by ADA. Decks are non-slip, or abrasive enough to also be in compliance with Code if slope was correct. Pool deck sealant is old and failing and needs to be replaced. Page 46
Typical deck drain painted yellow at each side. Deck drain is more a tripping hazard than drain. POOL DECK DRAINAGE, surface shall be sloped a minimum of ¼ inch per foot to deck drains or other approved surface water disposal areas. The pool deck surface shall not drain into the pool, its perimeter overflow channel or be connected to the pool recirculation systems. The decks slope away from pool at too great a slope to comply with ADA even though they probably drain splash out and storm water effectively. They also create an obstacle or tripping hazard for those than have to step over or on it. Slope is almost steep enough to require handrails being greater than 1/20 POOL COPING - shall be slip resistant. Pool coping and decks are slip resistant as they are precast concrete Page 47
Typical deck lighting POOL LIGHTING, underwater lights not provided only overhead lights Nighttime Use of pools requires underwater lighting fixtures that will provide complete illumination to all underwater areas of the pool with no blind spots. Illumination shall enable a lifeguard or other persons to determine whether: 1. A bather is lying on the bottom of the pool. 2. The pool water conforms to the definition of clear pool water. 3. When the pool is to be used at night, pool deck areas shall be provided with lighting so that persons walking on the deck can identify hazards and safely exit. Pool underwater lights are not provided only overhead deck lights, the light sources above water level are depended upon for any after hour use and are more for exiting allowing those on-deck to navigate the deck and identify hazards. However they are inadequate to ensure someone in the pool can be seen and monitored for safety. Exits must still be more clearly indicated and self-illuminated signage would be needed in case of an emergency. Underwater lights for afterhours use would be suggested however, based on the limited usage of this pool not advisable. After house or nighttime use is not recommended. Page 48
Typical toilets, urinals and showers, non ADA accessible BATHHOUSE, DRESSING, SHOWER AND TOILET FACILITIES Shower and dressing facilities shall be provided for pool users. Number of Sanitary amenities required: Current Pool Surface area: Pool 4,288 sf has a bather demand of one for every 15 square feet of pool water surface area. Bathers: 4,288/15 = 286 bathers are utilized to calculate amenities. Of the 286 half will be female and half male Showers. One shower shall be provided for every 50 bathers. 286/50= 5.72 or 6 showers Toilets. Separate toilet facilities for each sex. One toilet shall be provided for every 60 women, one toilet plus one urinal for every 75 men. 286/2= 143 women & 143 men 143/60= 2.38 or 3 women s toilets 143/75= 1.9 or 2 men s toilets and 3 men s urinals Lavatories. One lavatory shall be provided for ever 80 bathers. 286/80=4 lavatories Drinking Fountains. One guarded jet drinking fountain shall be provided for the first 250 bather s and an additional fountain shall be provided for each additional 200 bathers or fraction thereof. 286-250= 2 drinking fountains required. REQUIRED: Toilets: Women s: 3 toilets Men s: 2 & 2 toilets & urinals Toilets need ADA compliance Showers: 6 showers Lavatories: 4 sinks Drinking Fountains: 2 fountains Page 49
A lot of modification to existing changing areas will be required. ADA or Family changing area should be considered. A separate family style changing area with ADA access might also be considered instead of a bathhouse renovation. Hose Bibb s, do not seem to be close enough together to allow for proper deck cleaning HOSE BIBBS, shall be provided for and located so that all portions of the pool deck area can be reached with a 75-foot length of hose attached to the hose bibb. Hose bibbs shall be located so that they do not constitute a safety hazard and shall be protected against backflow. Hose Bibs are required and must be on a separate backflow (vacuum breaker) protected line and be properly located for maintenance of pool and decking. Pool automated fill as well as domestic water should each be isolated with a reduced pressure backflow prevention device. Page 50
Pool enclosure is a mix of chain link, CMU wall and wood fencing POOL ENCLOSURE, the pool shall be enclosed by one or a combination of the following; a fence, portion of a building, wall or other approved durable enclosure. The pool area is completely enclosed, the doors and gates granting access to the pool area should be self-latching and self-closing and have panic hardware as required for ADA access, with dedicated and self-illuminating EXIT signage as required. Chain-link when used to enclose pool has a material that is too wide and the material will need to be replaced. The largest dimension when measured knuckle to knuckle is 1.5 inches and this is 2.25 inches. As such it is easily climbable. None of the existing gates have proper hardware nor are they self-latching or self-closing. Page 51
Required occupancy, pool rules, save a life, 911, no running, pool rules etc. signs are not in existence REQUIRED SIGNAGE: Occupant Load Sign: A sign with clearly legible letters not less than 4 inches high shall be posted in a conspicuous place near the main entrance to a pool which shall indicate the number of occupants permitted for each pool. Signs for Shallow Pool. Signs with clearly legible letters not less than 4 inches high shall be posted in a conspicuous place and shall state: NO DIVING ALLOWED. Several signs are recommended from Occupancy Loading sign to no diving and no running signs. How to save a life, contacting emergency services 911 and pool rules. All should be added for patron safety including the EXIT signs and Accessible path of travel signs. Page 52
Only the pool pump had an equipment pad. POOL MECHANICAL EQUIPMENT: Pool equipment shall be mounted on a Portland cement concrete or other easily cleanable nonabsorbent floor material. Floors shall be sloped a minimum of 1/4 inches per foot to drains. New equipment will require equipment pads or old equipment will need pads. RECIRCULATIOIN AND TREATMENT SYSTEM COMPONENTS: Each pool will be provided with a separate recirculation and treatment system designed for continuous, recirculation filtration and disinfection of the pool water. The system shall consist of pumps, filters, chemical feeders, overflow systems, and all valves, pipes, connections, fittings and appurtenances. Installation shall allow for all filters, valves, pumps, strainers and equipment requiring adjustment shall be readily accessible for repair and replacement. Pool Data: Existing Pool Area = 4,288 sf Perimeter = 312-0 lf Depth = 1-0 to 9-0 (average = 5-0 ) Volume = 160,371 gallons (County Health states 156,200) so this calculation is close. Turnover = 445 gpm. (6-hours) Required filter area = 34 SF if HRSF Current filtration is from five manual high rate sand filters (Pentair s Triton TR-140 and they represent 7.06 sq.ft. ea., or 37.3 in total - and the required turnover is 160,371 / 360 = 445 gpm. The exact filtration area is estimated as well as probable filtration and backwash rates. There are approximately 37.3 sf of filter area (all filters combined) so each of the filters is filtering at between 16.3 gallons per square foot at the turnover rate of 445 gpm. Backwash should be as an individual filter at about the rate of 141 gpm., but valves do not allow individual filter backwashing so the backwash rate is the same as the filtration rate. An automated filtrations systems should be considered with a lower filtration rate. Page 53
Automated controller monitoring chlorine and ph - Flow meter above return pipe. (flow at 600 gpm) POOL WATER TURNOVER: Six hour or less for public pools supported by a recirculation and purification system with sufficient capacity to accommodate turnover. If the pool volume and layout do not change the current pump and filters are adequate unless turnover rate is modified. Most pool complexes have a separate wading pool because County Health would require that the wading pool have a 1-hour turnover rate. As part of the larger pool the entire pool would have to be at 1-hour. RECIRCULATION PUMP CAPACITY: Pumps with other hydraulic (flow-head) characteristics shall be permitted which comply with the flow capacity as required to accommodate a 6-hour turnover if a swimming pool. The turnover of your pool with current pump is at 6 hours as designed. Pipes are PVC and exposed and are within the required flow characteristics for pipe size and flow rate so the last renovation was after 1975. Page 54
Pool pump supply and returns exposed on outside of pool mechanical room RECIRCULATION PIPING: Piping systems, including all parts and fittings other than inlet devices, shall be sized so that the flow velocity shall not exceed 7 feet per second. The actual piping sizes are only apparent in the pool mechanical room and above and appear to be adequate based on the Code modifications accomplished since construction. Page 55
Backwash receptor is in the back of the mechanical room on the floor & strainer pot is just before pump STRAINER, a hair-and-lint strainer shall be provided on the suction side of the recirculation pump. Backwash Piping - including necessary valves is required for each filter vessel or element which is of a type requiring periodic backwashing. Both the strainer and backwash piping and re-circulation pump are in place as required. VALVES, shall be accessible for operation and repair and shall not be located under any required deck area surrounding a pool. Valves, or other approved means of control, shall be installed on all recirculation, backwashing, and drain system lines which require shut off isolation, adjustment, or control of the rate of flow. Each valve shall be identified with appropriate markings affixed directly to or near the valve. Appropriate valves were in place see photo above BACKFLOW PROTECTION, there shall not be a direct connection between any domestic water supply system and the pool or its piping system unless protected against backflow in an approved manner. Backflow protection was in-place with a break between the receptor and pool piping. (see above) DOMESTIC WATER SUPPLY PROTECTION, to the pool shall be supplied with water by means of a permanently installed pipeline from a public water supply system. A Reduced Pressure Backflow device was not noted and was not a requirement in the 1930 s. It will need to be added to the list of required improvements. The source of potable water to the pool should be verified and separated from other domestic water sources. FILTERS, regardless of type, shall be designed and constructed to withstand normal continuous use without deterioration which could affect filter operation The existing high rate sand filter vessels are in good condition. They are typically found in residential and not commercial pools but they seem to be functioning quite well I think that is Page 56
attributable to the low usage of the pool. Filters should remove all material visible to the human eye or 30 microns or greater. All smaller material is removed through oxidation and chemical treatment. Given your mechanical room space and conditions you are well suited for High Rate Sand filters and should perhaps consider automation. Acid Storage dual containment vessel & metering pump. Note lack of seismic restraint in mech. rm. CHEMICAL STORAGE AND FEEDING; Chemical Feeders - and the auxiliary components shall: 1. Capable of being easily disassembled for cleaning and repair. 2. Be constructed of corrosion-resistant materials. 3. Permit repeated adjustments without loss of output rate accuracy. 4. Be constructed to minimize a stoppage from chemicals intended to be used therein or from foreign materials that may be contained in said chemicals. Chlorine Feeder - shall also: 1. Be capable of supplying not less than the equivalent of 3 gallons of chlorine per day (PPD) per 10,000 gallons of pool water capacity. (160,000/10,000)=16 x 3 or 43 gallons per day, if dilute acid is utilized the metering pump and storage system should be able to feed about 10 gallons per day.) POOL SKIMMERS, shall be capable of continually withdrawing not less than 75 percent of the required circulation capacity, to provide continuous skimming of the water surface. Surge capacity is maintained within the pool as skimmer capacity or the six inches above the middle of the water line tile in your pool as there is no separate surge tank. The pool should have a surge capacity of 4,288 gallons. MAIN DRAIN PUMP SUPPLY OUTLETS, each pool shall be provided with a bottom drain and outlets through which circulation shall take place and by which the pool can be emptied. The bottom drain and recirculation outlets shall be covered with grates or other protective devices which shall be removable only with tools. Slots or openings in grates or covers shall not exceed ½ inch in the smaller dimension and shall be of such area, shape and arrangement to prevent physical entrapment or a suction hazard to bathers. Page 57
The pool has only a single main drain. A properly sized pair of main drains - in compliance with VBG is required and should not have flow greater than 1.5 FT3 per second at pool turnover rate. The estimated pool turnover rate for the pool is 445 gpm. Meaning that a main drain 2-0 square with covered of partially impeded grating will have a net open area of.5 sf. (allowable flow = 1.5 x 7.48 = 11.22 gps) or 2 x 11.22 x 60 = 1,346 gpm capacity which is greater than proposed turnover rate of 445 gpm. Conclusion; that the current pool vessel if retained will require a pair of main drains that can be are 1-2 square being adequate to each handle 100 percent of the flow from any one drain to prevent suction entrapment. Even though the skimmers have suction entrapment vacuum releases I do not believe they are required nor necessary. Safety is the largest issue here along with compliance with Federal Law in the Virginia Graeme Baker Act. POOL RETURN INLETS, pool shall be provided with not less than two recirculation inlets for the first 10,000-gallon capacity and one additional inlet for each additional 10,000-gallon capacity, or fractional part thereof, for a pool which exceeds 40 feet in width. Inlet fittings shall be separated by at least 10 feet and shall be located to ensure uniform circulation. The number of inlets required is 160,371 gallons / 10,000 = 16 floor inlets required. These should be balanced and adjusted to provide an even flow of treated water. WASTE WATER DISPOSAL General Requirements - Material cleaned from filters and backwash water from any pool system shall be disposed of in a manner which will not create a (public) nuisance. Piping - Sumps and drain piping shall have sufficient capacity to receive pool system backwash without overflow of the sump receiver. Prohibited Connection - No direct connection of the pool or its recirculation system shall be permitted with a sanitary sewer, storm drain or drainage system. When permitted by local regulations, discharge to a sanitary sewer shall be through an air-gap-type separation. Backwash of HRS filters is at a rate within of 16 gpm/sf or as determined above 113 gpm per filter. Each filter is backwashed separately for approximately four minutes. Approximately 452 gallons of pool water each and 2,260 gallons total is backwashed into the sanitary sewer system during each backwash. Current system for backwash is adequate for handling the backwash. Electrical Service Connection 3-pase breaker to pool re-circ pump Page 58
NEC Article 680 ELECTRICAL, Swimming Pools Ground-Fault Circuit Interrupters shall be self-contained units, circuit-breaker types, receptacle types or other approved types. Wiring- Conductors on the load side of a ground-fault circuit interrupter or of a transformer shall not occupy raceway, boxes or enclosures containing other conductors unless the other conductors are protected by ground-fault circuit interrupters or are grounding conductors. Supply conductors to a feed-through type ground fault circuit interrupter shall be permitted in the same enclosure. Ground-fault circuit interrupters shall be permitted in a panel-board that contains circuits protected by other than ground-fault circuit interrupters. Receptacles, Lighting Fixtures, Lighting Outlets, Switching Devices Receptacles that provide power for a water-pump motor, or other loads directly related to the circulation and sanitation system, a permanently installed pool shall be permitted between 5 feet and 10 feet from the inside walls of the pool or foundation and, where so located shall be single and of the locking and grounding types and shall be protected by a ground-fault circuit interrupter. Other receptacles on the property shall be located at least 20 feet from the inside walls of a pool and shall be shall be protected by a ground-fault circuit interrupter. Lighting Fixtures located less than 5 feet measured horizontally from the inside walls of a pool shall be at least 5 feet above the surface of the maximum water level, shall be rigidly attached to the existing structure, and shall be protected by a ground-fault circuit interrupter. Switching Devices, shall be located at least 5 feet horizontally from the inside walls of a pool unless separated from the pool by a solid fence, wall or other permanent barrier. Motors - wiring supplying pool pump motors rated 15 and 20 amperes, 125 volt or 240 volt, single phase, whether by receptacle or direct connection, shall be provided with ground-fault circuit interrupter protection. Cord & Plug Connected Equipment, fixed equipment rated 20 amperes or less, other than an underwater lighting fixture for a permanently installed pool, shall be permitted to be connected with a flexible cord to facilitate the removal or disconnection for maintenance or repair. The flexible cord shall not exceed 3 feet in length and shall have a copper equipment grounding conductor not smaller than #12 with a grounding type attachment plug. Overhead conductor clearances, pools shall not be placed under existing service drop conductors or any other open overhead wiring; nor shall wires be placed in the area extending 10 feet horizontally from the inside of the walls of the pool. Since there have been significant technological advancements in electrical service devices and specifically shock and stray current protection with regards to GFI protection of circuits, GFI receptacles, high efficiency lighting and switches. Electrical service should be addressed as well as its bonding, grounding, amperage and phase be replaced with new technology that will allow for 480v 3 phase power for pool mechanical systems that is monitored with a Variable Frequency Drive to control the higher horsepower pool recirculation pumps. The sub-panels should be gasketed. Bonding wire (CU#8) were not in evidence around the pool mechanical room. Proper bonding should be verified. Equipment Rooms - Electric equipment shall not be installed in rooms that do not have adequate drainage to prevent water accumulation during normal operation or maintenance. Disconnects - A disconnecting means shall be provided and be accessible, located within sight from all pools and shall be located at least 5 feet from the inside walls of the pool. Page 59
Disconnect for motors were not required at time of pool construction but should be placed with reconfiguration pool pump is not self-priming. A shut-off will be required. Common Bonding Grid - All the parts specified above Bonded Parts shall be connected to a common bonding grid with a solid copper conductor, insulated, covered, or bare, not smaller than #8. Connection shall be made by exothermic welding or by pressure connectors or clamps that are labeled as being suitable for the purpose and are of the following material: Stainless steel, brass, copper, or copper alloy. The common bonding grid shall be permitted to be any of the following: Structural reinforcing steel - of a concrete pool where the reinforcing rods are bonded together by the usual steel tie wires or the equivalent. A solid copper conductor, insulated, covered or bare, not smaller than a #8. Pool Water Heaters - rated at more than 50 amperes that have specific instructions regarding bonding and grounding, only those parts designated to be bonded shall be bonded and only those parts designated to be grounded shall be grounded. It is the common bonding grid that is difficult to verify, because the #8 copper wire was not in evidence throughout the pool mechanical room nor at the electrical panels. Metal equipment can be tested for continuity (to verify bonding). This test should be accomplished as the part of any proposed work, primarily because of the amount of electrical equipment on site. Proper bonding and grounding wires be on all metal components and that a SMPS (smart pump control system) or Variable Frequency Drive (VFD) be placed to regulate the pool recirculation pump and achieve operational economy. GFCI breakers be added as required and underwater lighting added depending on proposed program uses. We also suggest chemicals not be stored in same room with electrical equipment.

EXECUTIVE SUMMARY FOR POOL: Johnson Pool has utility as a community and recreational pool, for teaching/learning, exercise and limited competitive swimming. The pool however, creates many concerns, at it requires work to remain viable and the cost of performing modifications to the pool to modernize it will extend its useful life. However, its utility will remain about the same and it will be costly. In order to attain greater efficiency and utility a replacement pool should be considered as one of the potential solutions. There are many items to consider as indicated earlier in this report. Each is listed below under recommendations and assigned a cost to implement and listed in their perceived order of importance. RECOMMENDATIONS FOR POOL: 1.
