[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application was filed on August 20, 2018, and claims the benefit of U.S. Provisional Application No. 62 / 625,190, filed February 1, 2018, U.S. Provisional Application No. 62 / 629,211, filed March 6, 2018, and U.S. Provisional Application No. 15 / 990,314, filed May 25, 2018, which applications are incorporated herein by reference. To the extent appropriate, a claim of priority is made to each of the above applications.

[0002] FIELD OF THEINVENTION The present invention relates to a man-made, publicly accessible, urban beach recreation complex having as its centerpiece a man-made tropical-inspired lagoon containing a beautiful, clear wave feature with at least one surrounding recreational, educational, cultural, sports, or commercial facility, the complex having a controlled public access system and providing the feeling and impression of being on a tropical beach with clear water and sand.

[0003] The present invention also relates to a method of efficiently utilizing facilities and land that are vacant, underutilized, limited in use, and / or contiguous with or adjacent to recreational, educational, cultural, sports, or commercial sites by providing a publicly accessible, urban beach recreational complex with a lagoon that includes a centerpiece man-made, tropical-inspired, beautiful, clear wave feature. [Background technology]

[0004] background There are countless tracts of land in the world, including vacant lots, that are underutilized due to various factors. There are also a variety of recreational, educational, sports, and commercial sites that are contiguous with larger tracts that could potentially be developed profitably. Such lands that are used only in limited or no way at all generally require monthly or annual maintenance fees or taxes and generate little or no direct income from their use. For example, in the United States, it is estimated (by experts) that up to 25% of the total land area of ​​cities is vacant, and it is recommended that such spaces be managed more efficiently to meet the current and future needs of city dwellers. This vacant urban land includes land that can be used for future real estate development and other uses. In addition, there are also vacant lands, such as greenfields, brownfields, or agricultural or uncultivated land, that are found relatively close to the center of the land.

[0005] Examples of the various recreational, educational, sports, and commercial sites having such contiguous land include event arenas, museums, amusement parks, water parks, stadiums, golf courses, membership clubs, zoos, aquariums, shopping centers, college campuses, casinos, cruise ship docks, race tracks, horse racing tracks, and Olympic venues.

[0006] Investor surveys estimate that there are more than 100,000 such sites worldwide, many of which have adjacent or contiguous land that is currently underutilized or only used to a limited extent, creating a large global market for new and innovative concepts that utilize said sites efficiently and radically improve and change the lifestyle of the people living in their immediate vicinity. In addition, many of these sites have large infrastructures associated with them, such as parking lots, access routes, and large spaces that are unused or underutilized. For example, some stadiums are only used once or twice a week, and the rest of the time there is no alternative or additional use for the existing infrastructure. The same thing happens in the field of horse racing and race tracks, which are often not used or are only used during races (i.e., not used for alternative or additional purposes). In addition, some race tracks are closed and structures are not used efficiently.

[0007] It is also important to note that there are several major trends occurring around the world regarding retail sales right now. More specifically, shopping malls and stores are closing at an unprecedented pace. This creates large vacant spaces that can be reinvested and used for other purposes. It is estimated that one-quarter of all shopping malls in the United States will close within the next five years (according to a Credit Suisse forecast). In many cases, these spaces can no longer provide what the public desires, such as entertainment and cultural activities, gathering places to spend time with family and friends, other amenities, and environments that promote relaxation and improve physical and mental well-being.

[0008] Another important recent trend is the shift from explosive growth to high rates of golf course closures. According to Bloomberg, over 800 golf courses have closed in the United States in the past decade. The reason given in many cases is that golf is not a family-friendly sport, and people are looking for new activities and experiences to enjoy with family and friends, resulting in a decline in interest. Golf course closures leave operators with large tracts of land that may be abandoned. This creates a major problem as the vacant land may eventually become wasteland. Again, the closures reflect changing recreational and leisure preferences, people turning to outdoor recreational and cultural activities, valuing time with family and friends, and seeking new and aspirational gathering places.

[0009] Thus, the ever-increasing emergence of vacant, underused, or underutilized land, or land adjacent to or contiguous with recreational, educational, sports, or commercial uses, which have not been innovated for many years, represents an untapped market that could rival newly constructed mixed-use developments, appeal to those living near the mixed-use developments, and lead to more efficient use.

[0010] In addition to the availability of underutilized spaces, urban life and needs have also changed over the years. Publicly accessible open recreational spaces are declining due to urbanization and population growth. Life in big cities is often described as becoming more stressful. As the United Nations indicates, over 50% of the world's population lives in urban areas, creating a critical need to provide attractive, multi-purpose, especially outdoor recreational spaces that can help people escape their stressful daily lives and relax in peaceful, paradise-like environments. These trends are putting an end to the era of congregating in enclosed spaces such as malls, cinemas, and cramped gyms, and calling for open, paradise-like spaces to improve the lifestyles of people around the world.

[0011] Paradise tropical beaches have been found to be one of the favorite destinations of people all over the world. The desire to relax and enjoy outdoor experiences is universal, especially during summer and warmer months. Tropical environments and beaches are one of the most favorite spots of international travelers. Moreover, beaches are very popular with domestic travelers who want to get away from their normal daily lives and relax and rejuvenate in a tropical paradise. People generally visit and stay in recreational destinations, especially those close to the ocean and beaches. For example, according to the National Ocean Service, in the United States, the coastline is less than 10% of the total land area (excluding Alaska), but is home to 39% of the total population. However, many of the beaches along the coastline are not suitable for swimming, are windy, have black sand, and pose safety issues in terms of currents, surf, marine life, rocks, and / or other associated risks. This leads to a situation where many people do not swim or engage in water sports at or around such beaches.

[0012] Instead, people dream of white sand beaches with tropical turquoise waters. This dream includes being immersed in a beach environment, seeing and feeling the tropical surroundings, and enjoying a lavish lifestyle beside beautiful, clear, naturally rippling water. In addition to swimming, water sports are popular activities people seek out in these environments that cannot be done in backyard or community pools.

[0013] A traditional swimming pool simply cannot accommodate such gracious beach amenities. For purposes of this invention, based on its worldwide definition, a traditional swimming pool is an impermeable body of water constructed of concrete or similar material and, under Florida regulations such as Florida Department of Insurance Rule 64E-9, must filter all of the water in the pool four times per day in order to operate, and must maintain a permanent residual chlorine level of at least 1.0 ppm in all of the water.

[0014] Public pools provide a swimmable body of water, but do not address the key parameters necessary to create the look and feel of a beach lifestyle, an urban beach-type entertainment complex, and the feeling of being in a tropical environment. Some of the reasons include: (i) very high construction and operating costs, including electrical and chemical requirements, that limit their size - thus limiting their size to small pools, (ii) they generally use right angles, straight lines, and shapes that look artificial, (iii) they generally do not have a sandy beach area, (iv) their small size and shallow depth make the color of the water artificial and unnatural, (v) their size means they do not have a natural wave action as they do not have the fetch distance to create larger, more natural waves, (vi) they are shallow and small, so they do not allow for water sports, (vii) they have a strong chlorine or chemical odor, (viii) and, generally, they are not surrounded by a tropical or beach life landscape with a pier. For more information, (i) Traditional swimming pools are expensive to build and maintain and are typically constructed from thick concrete structures with an artificial appearance. - For example, a 15,000 m2 island in California 2 The "Fleishhacker Pool" in closed in 1971 due to water quality issues and high costs; there are several other examples of this happening around the world. - Based on the actual construction costs of a swimming pool, it would cost about 1,000 m 2 An Olympic-sized pool would cost approximately US$1.8 million in direct construction costs, use over 23,000 kWh of electricity per month, and over 25 gallons of chlorine per day, translating to direct operating costs of over $6,000 per month. Increasing the size and volume of such conventional pools would be prohibitively expensive to build, especially due to the use of thick concrete bottoms with waterproof coatings and expensive equipment for water conservation. Thus, it is economically and technically difficult to increase the size of conventional swimming pools, and they are never large enough to mimic tropical ocean waters and / or to host water sports. -The operating costs of large swimming pools are high and economically prohibitive due to the intense electricity consumption to filter the entire volume of water four times a day, and due to the use of chlorine to maintain high and permanent chlorine levels. Pools therefore have a very high carbon footprint, which affects the sustainability of such structures. (ii) Public swimming pools are typically constructed with straight lines, right angles, and rectangular geometries, which differ from natural, curved bodies of water resembling tropical oceans or coastlines. (iii) Swimming pools usually do not include a sandy beach area, giving them a more artificial appearance. Traditional swimming pools are usually constructed of thick concrete and covered with paint or tiles, which gives the appearance of an artificial structure used to fill with water, and not of a posh beachfront look with white sand beaches similar to those found in tropical regions. (iv) The colours and tones of the water achieved by swimming pools usually appear artificial due to their depth. Pools are usually only up to 1.5m deep, so the reflection of the sun from the bottom of the pool does not produce the beautiful deep turquoise colours found in tropical waters. Also, the size of the pools is small, giving the feeling of immersion in an artificial environment, not beach-like. (v) Because of their small size, the wave action generated by pools appears artificial due to the lack of surface movement. The small size and especially short length of the pools (the longest distance from one point on the pool's perimeter to another point within the pool's perimeter) creates a situation where the wind has no visible effect on the surface of a small pool. The effect of wind over long distances on the water's surface is called "fetch" and affects the movement of water's surface waves. Small pools with small surfaces do not have the fetch and therefore do not generate the larger, more natural looking wave action. (vi) Traditional pools also do not typically provide the conditions for water sports, as many require large surface areas and greater depths that cannot be achieved with traditional swimming pool construction and operation techniques because construction and maintenance on a large scale is technically and economically impossible. Water sports that are not typically performed in small pools include sailing, boating, windsurfing, waterskiing, waterskiing, flowriding, stand-up paddling, jet skiing, and kite surfing. For example, stand-up paddleboarding, one of the fastest growing water sports in the United States, cannot be performed in small pools because the desired sensation of paddling in a large space cannot be achieved. (vii) Many swimming pools have a strong chlorine or chemical odor because, due to operating techniques and worldwide regulations, they must maintain a permanent high residual chlorine level in the water for proper disinfection. The chemical odor therefore destroys the illusion of being in a tropical paradise and instead gives the impression of being in an artificial environment. Typically, swimming pools are required to maintain a minimum residual chlorine level of 1 ppm, which creates a very noticeable chlorine odor. (viii) The pools are generally not surrounded by tropical or beachy features such as palm trees, and do not usually have a jetty or pontoon because water sports are not usually offered in such small pools, thus not creating the look and feel associated with gracious beach life and a tropical paradise, including the ability to engage in some types of water sports. Summary of the Invention [Problem to be solved by the invention]

[0015] Based on the above, as city life becomes more stressful and going to Caribbean or other tropical beaches is out of reach for most people (e.g. due to time, money, distance or other constraints), the present invention overcomes the aforementioned urban problem of lack of recreational space in a novel and innovative way by bringing a beautiful tropical-inspired environment with beautiful clear water and white sand beach to underutilized urban land or sites through a man-made urban beach entertainment complex with a beautiful clear lagoon as its centerpiece. Such recreational areas are designed to change the lifestyle of people around the world by providing an elegant beach life environment that promotes relaxation and enjoyment of beautiful water, thereby reducing conscious and subconscious stress and improving physical and mental health. Around the central lagoon, various activities including recreational, social, cultural and sports activities can be conducted with the aim of transforming the site into a beautiful and desirable landscape.

[0016] Additionally, while there has been a rise in artificial wave technology in recent years, such technology has generally been incorporated as a stand-alone feature aimed at those who practice surfing and related sports, such wave-making devices have not been incorporated as part of a recreational complex such as that of the present invention, which incorporates additional facilities and amenities aimed at creating a 21st century gathering place. [Means for solving the problem]

[0017] Summary of the Invention The present invention discloses a man-made, publicly accessible, urban beach recreation complex having as its centerpiece a man-made tropical-inspired lagoon containing a beautiful, clear wave feature with surrounding recreational, educational, sports, and / or commercial facilities, the complex having a controlled public access system and providing the look and feel of a tropical beach with clear waters and sandy shorelines.

[0018] The present invention also relates to a method of efficiently utilizing vacant, underutilized, limited use, or adjacent or contiguous recreational, educational, cultural, sports, or commercial facilities and land by providing a publicly accessible urban beach entertainment complex with a lagoon that includes a centerpiece man-made, tropical, beautiful, clear wave feature, which can generate revenue and efficiency by combining vacant, underutilized, limited use, or adjacent recreational, educational, sports, and / or commercial land with an urban beach entertainment complex.

[0020] According to another aspect of the present invention, there is provided a method for efficiently utilizing land of limited use by creating a publicly accessible urban beach entertainment complex, the method comprising: 2 selecting a site for a water supply system for a watershed, selected from vacant, underutilized, limited use, or contiguous or adjacent to recreational, educational, sports, or commercial land, having a minimum surrounding population of 500,000 within a 50 mile radius connected by an access road and having a sufficient available water supply for use at the site; constructing a centerpiece lagoon having wavy and non-wavy portions, the non-wavy portions of the lagoon including bottom, perimeter, and 10,000 m2 of the lagoon; 2 ~200,000m 2and having a surface area of ​​between 2,500 m and 3,000 m2 to recreate the look and feel of a tropical lifestyle, a majority of the bottom being constructed from a flexible plastic material, at least a portion of the lagoon further including a zero entry edge resembling a natural beach edge, the wave portion including an artificial wave device configured to generate waves within the wave portion of the lagoon; and constructing at least one sandy beach area and rest area surrounding a perimeter of the lagoon, the sand in the sandy beach area having a light color, thereby resembling a tropical beach, and the surface area of ​​the sandy beach area and the rest area being at least 2,500 m2. 2 and connecting a water supply source to the lagoon by a water supply system, the water supply system providing water for filling and / or replenishing the lagoon; incorporating a water treatment system for treating water in the lagoon, the water treatment system being arranged and configured to use at least 50% less power than a conventional swimming pool centralized filtration system and having a filtering capacity and filtered water volume that is at least 50% less than a conventional swimming pool filtration system that filters the entire volume of water four times a day; and separating at least a portion of the lagoon, the beach area, and the rest area with a physical barrier, the area within the physical barrier being at least 50% less than a conventional swimming pool filtration system that filters the entire volume of water. A further method includes creating an urban beach recreation complex, the barrier being configured and arranged to limit access of individuals to the complex; disposing an access control system on at least a portion of the physical barrier, the access control system being configured and arranged to selectively permit admission of individuals to at least a portion of the urban beach recreation complex; and establishing at least one auxiliary facility selected from the group of commercial, recreational, educational, cultural, residential, and sports facilities within the recreation area, whereby individual admission fees provide revenue for the urban beach recreation complex and provide efficient use of limited use facilities or land.

[0021] Thus, embodiments constructed according to the principles of the present invention provide people around the world who live near urban centers with the ability to step away from their normal daily routine and enjoy a beautiful, beachy, tropical-inspired environment with a beautiful, clear lagoon with white sand as its centerpiece. These publicly accessible, urban beach entertainment complexes will become the gathering places of the 21st century and change the lifestyles of people around the world.

[0022] A publicly accessible urban beach recreation complex may include a wave feature that allows for the practice of sports such as surfing, body boarding, body surfing, etc. In addition, the wave feature may provide ocean-like sights and sounds that add to the beauty of a tropical beach.

[0026] Detailed Description The present invention discloses a man-made, publicly accessible, urban beach recreation complex having as its centerpiece a man-made tropical lagoon with surrounding recreational, educational, sports, and / or commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy shorelines.

[0027] The present invention further relates to a method for cost-effectively utilizing facilities and land that are underutilized or contiguous with or adjacent to recreational, educational, sports, or commercial sites by providing a publicly accessible urban beach entertainment complex with a man-made tropical, clear, clear lagoon as its focal point, which can generate revenue and increase efficiencies by combining vacant, underutilized, or contiguous recreational, educational, sports, and / or commercial sites with an urban beach entertainment complex with a man-made tropical, clear, clear lagoon as its focal point, which has controlled public access and therefore allows for paying admission of people to at least one portion of the complex. Transforming such sites into tropical paradises by creating an urban beach entertainment complex having as its centerpiece a beautiful, clear, man-made tropical lagoon with white sand, will result in efficient use of the site and revenues from charging admission fees to the complex and other revenues from the activities of the complex. As those skilled in the art will appreciate, the ultimate goal of any publicly accessible urban beach entertainment complex is profitable use.

[0028] As referred to herein, a "tropical lagoon" is a large body of water with crystal clear water, the tones and colors of which range from turquoise blue to emerald green, as occurs naturally in tropical environments (i.e., near tropical regions) at depths of 0.5 meters to 6 meters or more. Such tropical lagoons generally have light-colored bottoms from light-colored sands, and their different depths result in different tones within the same body of water, with clearer water at shallower depths and darker water at greater depths. These tropical lagoons constitute a quintessential Caribbean landscape as internationally recognized and known to the average public.

[0029] Also, as used herein, the term "urban" refers to a type of environment and location that has road connections and access and encompasses a population of at least 200,000 people within a 30 mile radius.

[0030] One advantage of the present invention is that it cost effectively creates a tropical paradise within a city by providing a publicly accessible urban beach entertainment complex with a large, beautiful, clear, tropical-inspired man-made lagoon as its centerpiece, and where recreational, cultural, sporting, educational and commercial activities can occur around the lagoon, including wave features, thus providing a desirable gathering place for the 21st century.

[0031] Another advantage of the present invention is that it provides a method for efficiently utilizing land sites, such as vacant land, currently underutilized land, or land that is contiguous or adjacent to educational, sports, recreational, or commercial land. The method of the present invention transforms these sites into tropical paradises by creating as its centerpiece an urban beach entertainment complex with a man-made tropical beautiful clear lagoon and white sand beach, with the land being efficiently utilized and the potential for revenue generated from charging admission fees to the complex (as well as revenue from other activities in the complex).

[0032] These cost-effective, publicly accessible urban beach recreation complexes represent an entirely new concept that allows people to visit vacation spaces anywhere in the world, even if they are only a few blocks away from home, and provide new recreational spaces and beach-like retreats on sites that were not previously used for that purpose. Complexes built according to the principles of the present invention transform sites into recreational family destinations, upgrading any site to the next generation of entertainment. For example, if you asked people 50 years ago where they would go to get active, they would say they would go to the park or go outside for a run; if you ask today, they would say they would go to the gym. Similarly, if people wanted to go to the beach, they would have to travel far away by car or plane, and would typically have to spend a long time traveling. However, the present invention creates a beach closer to home, thus dramatically changing people's lifestyles.

[0033] These publicly accessible urban beach recreation complexes and their centerpieces, large beautiful clear lagoons with a tropical look and feel, provide landscapes of unparalleled beauty with vast expanses of turquoise water that create a relaxing visual sensation. Thus, these settings create highly attractive and spectacular locations, the surroundings of which can be used for activities that are conducted today in less attractive locations and in very poor overall conditions. Thus, these urban beach recreation complexes and their centerpieces, large beautiful clear lagoons with a tropical look and feel, are destined to be the gathering places of the 21st century.

[0034] It is important to note that wave features that are part of the centerpiece lagoon are generally treated separately from the rest of the complex and usually have separate access control systems to allow the space to be rented for a period of time during which surfing or similar activities may be practiced. Such features are generally treated separately from the access control systems from the urban beach entertainment complex. All reference numbers below apply to the urban beach entertainment complex and the non-wave portions of the centerpiece tropical lagoon.

[0035] 1. Difference from existing places / activities As mentioned above, the era of limited locations such as malls and movie theaters being used as meeting and gathering places is coming to an end. Creating and operating an urban beach entertainment complex with a tropical atmosphere including a beautiful and clear lagoon surrounded by sandy beaches will create a unique environment for 21st century gathering places. Thus, an urban beach entertainment complex may replace traditional promenades and parks with an urban beach environment where various cultural, recreational, educational and commercial activities take place.

[0036] With regards to shopping malls, as mentioned above, customer trends are changing and customers are spending more on experiences such as travel, entertainment, and dining. This, along with the growing trend of online shopping, has led to the closure of many stores and malls around the world. By having these publicly accessible urban beach recreational complexes with manmade beautiful clear lagoons with a tropical look and feel as their centerpiece and incorporating shopping centers into their surroundings, this solution helps protect the mall's business by providing customers with more than just a point of sale (e.g., by providing a new and transformative shopping experience). Customers can enjoy the entire day at the mall while shopping, eating, lounging, or relaxing in the common areas (the term "hanging out" is often used to describe this type of behavior in relation to malls). At the same time, customers can enjoy a day at the beach with a tropical feel with all the additional amenities. This has not been done before and is expected to have a huge impact on this market, and successful shopping center designs will incorporate such urban beach recreational complexes that include entertainment, dining, and leisure components. Shopping centers need to provide a unique and memorable experience that keeps customers returning time and time again. Thus, malls looking to innovate their offerings and become 21st century gathering places will find it desirable to build and incorporate a publicly accessible urban beach complex in accordance with the principles of this invention.

[0037] In addition, activities such as jogging and walking have been carried out in enclosed spaces or vegetated parks, but no mention has been made globally of publicly accessible beach environments within cities that offer the opportunity to view beautiful tropical-style crystal clear lagoons.

[0038] Furthermore, there is a growing demand for outdoor weddings in elegant surroundings and a move away from crowded, cramped wedding venues. One popular alternative is a tropical-inspired beach wedding. Thus, a publicly accessible urban beach developed according to the principles of the present invention may provide a popular location for wedding ceremonies and receptions.

[0039] Other activities and events that are usually held in less attractive locations are concerts, which take place in closed stadiums or arenas, or in large, open areas reserved for such events, and generally lack beautiful landscaping or surroundings.

[0040] The complex constructed according to the present invention creates a beautiful environment and includes numerous activities that circulate around a central tropical lagoon. Features of the complex may include night-time illumination, bars and restaurants to meet friends and family, screens, stages and amphitheatres for different recreational, cultural, educational or sporting activities, all leading to an environment where great experiences can be had and people's lifestyles can be enhanced. In addition, a portion of the lagoon includes a wave feature that is used to provide waves and make it suitable for surfing purposes.

[0041] II. Differences from pools and water parks It is important to note that these publicly accessible urban beach entertainment complexes are very different from traditional water parks. Current water parks are a completely different concept since their primary purpose is to provide slides, rides, and water features for visitors. Such water parks do not provide a tropical environment with the look and feel of a beach, but rather provide visitors with rides and experiences within the park. In contrast, the publicly accessible urban beach entertainment complexes of the present invention aim to provide a beautiful, clear, man-made tropical-inspired lagoon as a centerpiece around which various recreational, cultural, sports, educational, and commercial activities can take place. These activities would virtually not exist without the centerpiece lagoon. Thus, instead of having a water park with several small pools and rides operated with traditional swimming pool technology, the urban beach entertainment complex provides a 21st century gathering place by allowing an array of recreational, cultural, sports, educational, and commercial activities to take place around a lagoon as the centerpiece of a beautiful and attractive environment.

[0042] With regard to the technology required to construct and operate a beautiful, clear tropical-inspired centerpiece lagoon, it is important to understand that a traditional swimming pool does not provide the conditions that allow such a gracious beach lifestyle amenity to exist. While a pool may provide a swimmable body of water, it does not address the key parameters necessary to create the look and feel of a beach, an urban beach entertainment complex, and the feeling of being in a tropical setting.

[0043] Additionally, the costs of water parks are very high, much more so than urban beach recreation centers such as the one according to the present invention.

[0044] For example, a water park in South Dakota is about 1,000 m2 long, using swimming pool technology. 2 , 600m 2 , and 700m 2 (Total 2,300m2 ), with an estimated construction cost of approximately $5 million (considering only the three hydrofoils and associated equipment), covering an area of ​​1.2 hectares (12,000 m 2 The estimated construction cost for an urban beach recreation complex with a lagoon of 1.5m² is approximately $1,800,000 (considering only the centerpiece lagoon and associated equipment). It is important to note that these costs do not include the wave portion of the lagoon or the requirements for its construction or operation, since such artificial wave-making devices are typically provided by third parties and are usually located in a portion of the centerpiece lagoon. Such wave portions are typically roped off or demarcated in such a way that people cannot access the wave portion from the remainder of the lagoon.

[0045] Additionally, operating costs for the water park are estimated at $20,000 per month, including electricity and chemicals, while operating costs for the 1.2 hectare centerpiece lagoon (not including the waves) are estimated at $4,000 per month, including electricity and chemicals, based on a study conducted by Stantec, an independent construction firm that has designed and built such water parks in South Dakota.

[0046] Unlike traditional public swimming pools, these publicly accessible urban beach recreation complexes with large man-made clear, clear lagoons offer numerous advantages, as outlined in Table 1 below.

[0047] [Table 1]

[0048] [Table 2]

[0049] The above mentioned swimming pool construction and operation techniques have always been used in water parks. As mentioned above, water parks have different purposes, construction methods, operation techniques, and many other characteristics that distinguish them from the urban beach entertainment complex of the present invention. Some differences of the present invention technology compared to conventional water parks are listed below in Table 2.

[0050] [Table 3]

[0051] [Table 4]

[0052] [Table 5]

[0053] It may be possible to increase the overall valuation of adjacent or adjacent sites by creating these publicly accessible urban beach recreation complexes and creating a beach lifestyle in a cost-effective and sustainable manner anywhere in the world. In addition, the creation of these complexes may also increase the value of neighboring buildings, homes, and any other facilities or amenities close to the complex. Valuations may be much higher when there are commercial or residential buildings with direct views of the urban beach recreation complex and its beautiful, clear tropical lagoon, due to the aesthetics and the feeling of being on a beachfront district. Urban beach recreation centers may also create and increase value in the entire zone in which they exist, as it increases the value of the city by creating beach life closer to people's homes.

[0054] III. Parameters of urban beach recreational complexes and lagoons In accordance with the present invention, a man-made, publicly accessible, urban beach recreation complex is provided, the complex including as its centerpiece a large, beautiful, clear, tropical-inspired lagoon having a tropical look and feel.

[0055] Additionally, at least a portion of the focal tropical lagoon includes at least one wave-making device for providing a wave area over at least a portion of the lagoon. Thus, the lagoon is divided into a wave section and a non-wave section, the wave section generally housing the artificial wave-making equipment and surrounding the area where waves are generated. By positioning the artificial wave-making means in a suitable area of ​​the lagoon, the resulting waves may be used for surfing, bodyboarding, body surfing, and other activities. The artificial wave-making means is configured to generate waves by using the same waves as those of the artificial beautiful and clear lagoon and is installed in a portion of the lagoon. Moreover, preferably, such portion of the lagoon for generating waves and practicing surfing does not exceed 50% of the total lagoon area. Based on the configuration of such wave area in the focal lagoon, such wave generation may also provide water movement in the beach area, thereby recreating natural beautiful ripples.

[0056] The tropical, clear, non-wave portion of the urban beach recreation complex of this invention will incorporate bottom, perimeter, and 8,000 m of surface area to create a beach lifestyle and tropical look and feel within a publicly accessible urban beach recreation complex. 2 ~10,000m 2 The use of a lagoon smaller than this would not reflect a tropical environment. Instead, it would resemble a traditional home pool or hotel swimming pool, which does not provide the necessary conditions to have an immersive feeling in an elegant beach lifestyle.

[0057] In addition, the tropical lagoon has a maximum surface area of ​​approximately 200,000 m 2because a larger surface area would not provide the desired look and feel. For example, if the area of ​​a lagoon is 200,000 m 2 When a person looks beyond the shoreline to the opposite side, they may not be able to see the opposite waterfront area and other facilities and amenities, thereby not creating the desired waterfront recreational experience as disclosed in the present invention. One skilled in the art will appreciate that the lagoon may be arranged and configured such that it is longer than it is wide. In such instances, a larger size may be constructed while still achieving the desired look and feel.

[0058] Referring now to Figure 1, there is shown an exemplary urban beach entertainment complex 1 having a focal point, tropical-style, man-made lagoon 2. The lagoon 2 includes at least one zero-entry sandy beach area 3a, a bathing zone 3b, and a water sports zone 3c, each disposed within the larger, tropical-style, man-made lagoon 2. Figure 2 shows a schematic side view of an embodiment of the zero-entry beach edge 3a.

[0059] 1 and 2, the bathing zone 3b is adjacent to a zero-entry beach edge 3a, which preferably resembles the natural gradual slope of a tropical beach or natural lake. The zero-entry edge generally creates an entrance to the lagoon that starts at a height slightly above the mean water level 4a, passes through the mean water level at the periphery 4b of the lagoon, and then drops below the mean water level towards the centre 4c of the lagoon. The slope of the zero-entry edge is represented by the angle α shown at 5 in Figs. 2 and 3, and is defined by the angle between the horizon (generally parallel to the mean water level) and the sloping beach entrance. Preferably, this angle is between 5% and 30%. This range generally resembles a natural beach edge with a gradual slope, providing people on the sandy beach area 6 and people bathing in the water with a good, unobstructed view of the extensive clear water.

[0060] Water bath zone 3b also includes a localized sterilization system, which provides a higher chemical concentration in such zone. The localized sterilization system includes an outlet positioned and configured to apply a sterilizing chemical to a volume of water within the water bath area. The localized sterilization system is best seen in FIG. 3, which shows a peripheral chemical application system 7a and a bottom chemical application system 7b. The chemical application system includes one or more systems selected from the group including nozzles, injectors, jets, piping, and inlets.

[0061] The chemical application systems may be located at the periphery of the lagoon and generally bounded by the swimming zone, with the primary impact of the germicidal chemicals acting primarily within the swimming zone. The chemical application systems may preferably be located at the bottom of the swimming area, including a plurality of outlets, the outlets being located at the bottom of the lagoon within the swimming zone, whereby the primary impact of the germicidal chemicals acts primarily within the swimming zone. There may also be a combination of perimeter chemical application systems 7a and bottom chemical application systems 7b. It is recognized that the number and specific locations and configuration of chemical application systems selected will be determined on a case-by-case basis as best suited, taking into account the expected number of bathers, the volume of water, the flow of water from within the swimming area into the remainder of the tropical lagoon, etc.

[0062] Referring again to FIG. 1, the water sports zone 3c includes a minimum water depth ranging at least above 1.5 meters, and preferably above 1.8 meters. This minimum water depth allows the practice of water sports that would not be possible in a conventional small swimming pool. The water sports zone can have various slopes at the bottom, depending on its design and configuration. If the overall size of the lagoon 2 is between 10,000 and 200,000 m 2In the water sports zone 3c, various water sports can be enjoyed, such as sailing, boating, canoeing, kayaking, tubing, water skiing (barefoot skiing, water skiing, jet skiing), flyboarding, paddle boarding, parasailing, boating, wakeboarding, windsurfing, kiteboarding, kite surfing, etc. Preferably, the size of the lagoon 2 is about 15,000 m2 in order to enjoy water sports such as water skiing. 2 The artificial wave maker 25 is also configured to generate waves in at least a portion of the lagoon designated as wave portion 26.

[0063] As mentioned above, traditional swimming pools at water parks are small, usually measuring 1,000 to 1,500 m. 2 , and the maximum depth is generally less than 1.5 meters. Thus, they do not create the feeling of being at the beach or the beach lifestyle and do not allow for some water sports to be performed. In contrast, a beautiful, clear tropical-style lagoon 2 constructed according to the principles of the present invention has a minimum depth of 1.8 meters at the deepest part of the water sports zone 3c, and is often even deeper in most of the water sports zone 3c. This allows for the performance of countless water sports using a variety of techniques not found in conventional swimming pools.

[0064] 1 and 4, several possible embodiments of the complex are shown, with like items and structures designated with like numerals. In various embodiments, at least one sandy beach area 6 is provided, which surrounds a large, beautiful, clear tropical lagoon 2, with the sand being bright in color, like a tropical beach. In preferred embodiments, the color of the sand is similar to or within the following colors according to the RAL color scale: RAL 9001, RAL 9002, RAL 9003, RAL 9010, RAL 9016, RAL 9018, RAL 1001, RAL 1014, RAL 1004, or similar colors.

[0065] The sandy beach area 6 is generally configured directly in front of a zero-edge beach edge 3a located at least part of the periphery of the focal lagoon to provide the sensation of being up on the beach from the water. The sandy beach area 6 and additional rest areas have a minimum surface area allowing recreational, educational, sporting and commercial activities. The sandy beach area 6 and additional rest areas preferably have an area of ​​at least 2,500 m 2 , thereby allowing such areas to be highly usable for a variety of activities, such as concerts, plays, film screenings, sports, and other activities and events.

[0066] Also, unlike traditional pools with sharp edges and closed shapes, the non-wave tropical centerpiece lagoon is preferably designed with a curved shape with rounded corners reminiscent of natural water bodies and beaches, conveying the feeling of being in a gracious beach paradise.

[0067] Additionally, in some embodiments of the present invention, at least a portion of the urban beach entertainment complex includes the use of vegetation to create a tropical appearance. In a preferred embodiment, vegetation 8 resembling a tropical environment is located in the sandy beach area or additional rest areas surrounding or adjacent the zero entry beach edge 3a and / or sandy beach area 6.

[0068] 4, the urban beach recreation complex 1 further includes a water supply system 9 operatively connected to the water supply, which includes a water source, pumps, devices, and other suitable fluid conduits for providing water to fill and replenish the lagoon 2. As will be appreciated by those skilled in the art, the devices and conduits for providing water to fill and replenish the lagoon may include piping, nozzles, waterfalls, inlets and outlets, valves, and the like. The water replenishment system is preferably positioned and configured to provide fill and replenishment water to the lagoon to permanently maintain the volume of water within the body of water at at least 80% of the design volume.

[0069] The make-up water should have a maximum concentration of 2 ppm iron and magnesium to provide suitable water that will not change appearance when processed into the focal point tropical, beautiful, clear lagoon. As one skilled in the art will appreciate, for example, high concentrations of iron and magnesium will cause very noticeable color changes when processed. Also, the make-up water should have a turbidity of 8 NTU or less to avoid cloudy water (i.e., such water will not provide a tropical look and feel and clarity). Because the filtration level of the focal point lagoon of the present invention is lower than that used in swimming pools, it is important to control the quality of the incoming water to meet the above parameters.

[0070] The man-made, tropical, beautiful, clear lagoon 2 of the present invention is preferably the centerpiece of an urban beach entertainment complex 1 and is constructed and maintained with innovative techniques that result in low construction and operating costs that are less than one-tenth the construction costs associated with traditional thick concrete or tile bottoms used in swimming pools. Furthermore, such operating costs are less than one-tenth the operating costs of a traditional swimming pool, which requires the entire volume of water to be filtered four times per day.

[0071] By lowering construction and operating costs, while at the same time enabling aesthetically pleasing and high physicochemical and microbiological water quality to be achieved, a publicly accessible urban beach recreational complex 1 is provided in a cost-effective manner. Thus, the method of the present invention provides for cost-effective utilization of land that is vacant, previously underutilized, or contiguous with or adjacent to recreational, educational, sports, or commercial sites, and therefore provides for the commercial viability of such sites.

[0072] In order to provide a cost-effective urban beach recreation complex, the construction methods for building the non-wave portions of the lagoon shell typically do not include a concrete bottom of the type used in construction methods for swimming pools in the majority of the lagoon. Conventional swimming pool construction requires that the pool shell (bottom and walls) be constructed of concrete of a certain thickness, generally a minimum of 2-6 inches, which may be reinforced to provide structural stability and resistance depending on the type of soil under the pool. Additionally, such concrete bottoms are typically painted with a waterproof coating or covered with tiles, which makes the construction process more difficult and more costly.

[0073] In contrast, in the present invention, the majority of the bottom of the non-wave portion of the large centerpiece lagoon is covered with a flexible plastic material to provide waterproof and containment properties while providing a different feel than the concrete bottom of a typical swimming pool. Preferably, the bottom of the water sports zone in the beautiful, clear tropical lagoon is constructed such that at least 80% of its surface is covered with a flexible plastic material. The plastic material is selected from the group including polyvinyl chloride, polyethylene, rubber, polypropylene, etc. In a preferred embodiment, polyethylene may be used. The color of the plastic material ranges from pure white to light blue or light brown.

[0074] The bottom of the tropical lagoon may also be constructed of different materials providing additional layers. In one embodiment of the invention, the bottom of the large lagoon is covered with a mineral layer that creates an essentially stagnant body of water to retain the volume of water. In another embodiment of the invention, the bottom may be covered with a thin layer of shotcrete less than 6 inches thick.

[0075] It is important to note that technology currently exists to construct large, tropical centrepiece lagoons in a cost-effective manner for less than $600,000 (USD) per acre (such amount will vary based on country, overall size and specific local variables) and maintain good physicochemical and microbiological water quality using minimal amounts of chemicals and energy. 2 For a conventional water park with three relatively small features, the total direct construction costs would be over US$5 million (a direct comparison would be US$20 million per hectare, and only considers the water surface), based on a study conducted by Stantec, an independent construction firm that designed and built one such water park in South Dakota.

[0076] In addition, the publicly accessible urban beach recreation complex includes a low-cost treatment system that provides water treatment technology that uses at least 50% less power than a conventional swimming pool centralized filtration and disinfection system, and the capacity and volume of filtered water of the water treatment technology is at least 50% less than a conventional swimming pool filtration system that filters the entire volume of water four times per day.

[0077] For example, using conventional pool technology, a 30,000m 2 , volume 45,000m 3 In the case of the lagoon, the amount of filtered water is 180,000 m per day. 3 (Total amount of water is filtered 4 times a day = 45,000 m 3 ×4=180,000m 3 / day). In contrast, the preferred water treatment technology of the present invention includes a filtration system that filters at least 50% less water than that of a conventional swimming pool filtration system. By the same example, the filtration capacity and water volume of the present invention is up to 90,000 m 3 / day, resulting in significant electricity and equipment savings.

[0078] In an embodiment of the present invention, the focal tropical lagoon utilizes a modular treatment system 10, which includes one or more elements selected from the group including a centralized mechanical room, a skid-mounted system, and / or a water treatment facility. In a preferred embodiment, such a modular treatment system is arranged and configured in a plug-and-play manner, which allows it to be easily connected to other elements, equipment, systems, piping, and structures. In another embodiment of the present invention, the modular treatment system 10 is portable and can be deployed and installed on-site for a short period of time. Another advantage is that the modular treatment system 10 may be operated temporarily depending on seasonality, its configuration, and demand. An example of a preferred modular treatment system that may be utilized in connection with the present invention is a group of vessels manufactured to house different systems and equipment that can be manufactured locally or outsourced to other cities or even other countries.

[0079] In a preferred embodiment of the present invention, the low cost treatment system produces no discernible chemical odor in most of the lagoon as a conventional swimming pool would have a permanent residual chlorine level of 1 ppm throughout the entire volume of the water. The virtual absence of a discernible chemical odor in most of the lagoon helps achieve the goal of providing the look and feel of a posh beach with white sand, such as a Caribbean beach.

[0080] In another embodiment of the present invention, the water treatment technology to operate the focal tropical lagoon must use at least 50% less chemicals than conventional swimming pool disinfection systems that must maintain a chlorine level of at least 1 ppm in the total volume of the water, such as conventional public swimming pool regulations by the CDC (US Center for Disease Control), Florida Department of Health Rule 64E-9, and Title 22 - Division 4 - Chapter 20 of the California Code of Regulations.

[0081] Furthermore, the focal tropical lagoon 2 may preferably have a natural surface ripple due to its large surface area. The horizontal distance of the lagoon 2 in the direction of the wind may be the fetch, which is the horizontal distance over the open water over which the wind blows and creates waves. Thus, the appearance of waves in the tropical lagoon may be similar to the ocean and have a natural appearance that is very different from those created in a small conventional swimming pool. Depending on the horizontal distance parallel to the wind blowing over the lagoon, the waves created on the lagoon will be higher and more similar to ocean waves. The height of the waves will increase exponentially with the fetch and wind speed, an effect that cannot be achieved in a small conventional swimming pool. This would complement the use of artificial wave makers in parts of the lagoon, which also help to create waves that help provide movement to the water surface in the lagoon.

[0082] In an embodiment of the invention, the beautiful, clear tropical lagoon operates in an essentially closed cycle, where the volume of water is not significantly replaced through recirculation with a water source (e.g., a well) and / or an open body of water or river.

[0083] In one embodiment of the present invention, the tropical clear lagoon has a minimum vertical transparency of 1.2 meters to resemble a clear water tropical ocean when the wave maker is not in operation. Such depth allows for the intense colors of the clear water to be produced and the tropical lagoon bottom 11 can provide such intense colors and tones from the effect of the sun reflecting off the bottom and from the clarity of the water.

[0084] There are new and innovative methods for establishing and maintaining large bodies of water with excellent microbiological and physicochemical water quality and high transparency for different applications, which are protected by patents in the United States and around the world, and are described and illustrated, for example, in the following issued U.S. patents: U.S. Patent No. 7,820,055, U.S. Patent No. 8,070,942, U.S. Patent No. 8,062,514, U.S. Patent No. 8,790,518, U.S. Patent No. 9,708,822, U.S. Patent No. 9,470,007, U.S. Patent No. 9,080,342, U.S. Patent No. 8,465,651, U.S. Patent No. 9,062,471, U.S. Patent No. 8,753,520, U.S. Patent No. 9,957,693, and U.S. Patent No. 9,470,008. Each of the above patents is incorporated herein by reference and made a part hereof.

[0085] Such innovative methods, systems, and apparatus may be used as an alternative method to build and / or maintain large, beautiful, clear lagoons that have a tropical look and feel, with very low construction costs and very low operating costs due to the minimal use of chemicals and energy to maintain water quality. These patent protected methods, systems, and apparatus may be used to build and / or maintain large, beautiful, clear lagoons 2 by using all or any part of the techniques or components described in such techniques.

[0086] The above-referenced patents, incorporated herein, describe various operations and processes for treating large lagoon water in a manner that efficiently and economically maintains the water. While reference should be made to such patents for detailed descriptions, a brief description of a representative method for maintaining water in a publicly accessible lagoon is provided below. First, the water treatment and filtration process involves collecting water and storing such water in a vessel having a bottom that can be thoroughly cleaned by an aspirator. Second, the process involves treating the water in the vessel at seven day intervals by periodically adding a disinfectant to said water to provide an ORP of at least 500 mV for a period of time that depends on the temperature of the water being treated. Third, the method involves activating the operation of a mobile aspirator to aspirate a portion of said water in the vessel, including settled solids, such that the settled material does not exceed 3 mm in thickness. Finally, the method involves filtering the portion of the water aspirated by the mobile aspirator and returning the filtered water to said vessel. Using these processes, at least 50% less filtering capacity and water volume is filtered compared to when traditional swimming pool filtration systems are used, which require the entire volume of water to be filtered four times a day.

[0087] It is important to state that the aforementioned patented technology has been used in real estate developments with completely different concepts and configurations. In addition, such developments do not contemplate use by the general public in large numbers and do not create 21st century gathering places. In fact, real estate developments are very different because such lagoons are intended for use by the owners and residents, do not have public access control (e.g., entrance fees) for large-scale use, and may not be located on populated urban sites. Thus, they cannot create 21st century gathering places surrounded by amenities and facilities such as restaurants, theaters, stages, concessions, rental centers, shopping centers, gyms, promenades, bars, coffee shops, etc. Thus, the real estate models are entirely different. However, if there is a real estate development, hotel, or private development in a zone near a publicly accessible urban beach entertainment complex or around a focal tropical lagoon, to which the lagoon has private access, the principles of the present invention require at least one public access zone, separate from such developments and with access control for public use as a mixed use.

[0088] Therefore, as described throughout this specification, swimming pool technology is not scalable to large bodies of water where some other technologies are used, such as those used in surf lagoons, aesthetic or decorative lagoons, but which do not provide the beautiful clarity or water quality conditions of the present invention and would not be able to create the urban beach entertainment complex of the present invention.

[0089] In an embodiment of the invention, evaporation inhibitor chemicals are added to the lagoon water, which can reduce natural evaporation by up to 50% compared to the natural evaporation rate. It will be appreciated that the chemicals must be approved for use in recreational water bodies. Examples of preferred evaporation inhibitor chemicals include alcohol-based evaporation inhibitor chemicals or silicone-based evaporation inhibitor chemicals, which create an invisible layer on top of the water surface, thus reducing evaporation by avoiding direct contact between the water surface and the surrounding air. The inhibitor chemicals operate at different temperatures and can withstand wind conditions. Evaporation inhibitor chemicals must be approved by the NSF (National Sanitation Foundation) for use in recreational water bodies, and are approved under either NSF 50 (for swimming pool chemicals) or NSF 60 (for drinking water chemicals). An example of a preferred evaporation control chemical is Heatsavr® Crystal Lagoons Formula, manufactured by Flexible Solutions, Inc. of Canada. Such chemicals may be added manually, by the water make-up system 9 and / or by the modular treatment system 10 .

[0090] The urban beach entertainment complex also includes at least one access control system 12, which preferably limits and controls user access to at least a portion of the complex on a daily basis. The access control system is located at at least a portion of the physical barrier 16. The access control system 12 includes one or more access control stations 13 having a control system 14 capable of controlling admission to the public through such locations. Such control systems may include gated entrances, turnstiles, biometric systems, access readers, security barriers, biometric systems, and the like. In a preferred embodiment, the control system includes a gated entrance having a turnstile. Additionally, FIG. 5 illustrates a sequence 15, in which steps 15a-15c may control access to at least a portion of the urban beach entertainment complex by paying an admission fee.

[0091] FIG. 4 shows a schematic diagram of an embodiment of the present invention where a physical barrier 16 restricts entry of people to an urban beach entertainment complex 1 and allows access to the complex through an access control station 13.

[0092] The public accesses the inner-city beach recreation complex through access control station 13, as the remainder of the inner-city beach recreation complex confines must be physically restricted to prevent uncontrolled access.

[0093] 11 illustrates an embodiment of the access control system 12 and shows a point of sale 24 through which people pay an admission fee. In other embodiments, people may use a pre-purchased ticket or seasonal pass to access at least a portion of the urban beach entertainment complex and may not need to pay an admission fee on-site. In the illustrated embodiment, people purchase a ticket on-site and then optionally go through security screening 23 and enter the urban beach entertainment complex using one of at least one control system 14, in this case access control station 13, which includes a turnstile.

[0094] The access control system is configured to allow the public access to the complex and requires that certain barriers be used. Such barriers are defined as physical restrictive structures installed at the boundaries of the urban beach recreation complex or at the portions of it where access is controlled. The barriers may include one or more combinations of elements selected from the group including fences, walls, moats, natural plantings, buildings and parts of buildings, or other types of barriers to prevent the public from accessing the urban beach recreation complex 1 through any location other than the location of the access control system 13. It will be appreciated that the barriers will vary from complex to complex depending on the location and existing structures (if any). It will also be appreciated that one-way escape routes may be installed at the barriers and / or at the areas of exits that typically trigger warning sounds or sirens.

[0095] Preferably, the access control system is configured to allow access to the urban beach entertainment complex 1 or part thereof to at least 500 people per hour. For example, in an urban beach entertainment complex having a total area of ​​40,000 m 2 For the urban beach entertainment complex 1, the access control system 12 may include two different access control stations 13, each having at least four control systems 14, e.g. turnstiles, to allow a total of at least 500 members of the public per hour to access the urban beach entertainment complex through such turnstiles. Preferably, at least one of the control systems 14 and the access control stations 13 can be opened or closed depending on public demand.

[0096] The urban beach entertainment complex also includes at least one ancillary facility selected from the group of commercial, recreational, educational, cultural, residential, and / or sports facilities that surround the focal tropical artificial lagoon and allow for a variety of activities within the urban beach entertainment complex. The ancillary facilities 17 are selected from the group consisting of restaurants, shopping centers, event centers, gyms, stores, sports facilities 17e, and educational or cultural venues based on their configuration, etc. Ancillary facilities 17 are shown in FIG. 1. Such ancillary facilities and amenities may be operated by third parties.

[0097] The urban beach entertainment complex preferably further includes at least one beachfront amphitheater and / or space with a stage to accommodate and / or display various events, educational activities, concerts, cultural activities, sporting events, and the like. The urban beach entertainment complex may also include at least one large screen to display movies, sporting events, conferences, television and radio broadcasts, live streaming content, e-sports, educational activities, events, and the like.

[0098] The urban beach entertainment complex of the present invention may also include a lighting system 18 (best seen in FIG. 4 around the lagoon 2) to illuminate the tropical lagoon for use at night or under an enclosed structure. Underwater lighting allows the lagoon 2 perimeter to be clearly identified and also illuminates the water through underwater lights to create a completely new aesthetic look for nighttime beach ambience. The lighting system 18 includes LED underwater strip lights or underwater spot lights. The lighting system may be used around the entire perimeter of the tropical lagoon 2 or just a portion of the lagoon. One embodiment is shown in FIG. 4 where the lighting system 18 is used around a portion of the lagoon 2 perimeter.

[0099] A pier 19 (best seen in FIG. 4) may be provided in a beautiful clear lagoon, which is not the case for a swimming pool as a beautiful clear tropical lagoon allows water sports to be carried out and a pier is required to access the deeper parts of the lagoon. FIG. 4 shows the use of a pier 19 in a tropical lagoon 2.

[0100] IV. Method Description 6, the method 20 of the present invention, including steps 20a-20g, provides a method for efficiently utilizing facilities and land that are vacant, underutilized, or adjacent to recreational, educational, sports, or commercial sites by providing a publicly accessible urban beach entertainment complex with a beautiful, clear, man-made tropical-inspired lagoon as its centerpiece. The method provides an opportunity to generate revenue and allows for the creation of a publicly accessible urban beach entertainment complex located on underutilized or vacant sites with infrastructure for a particular population density and access, with the goal of creating a 21st century gathering place.

[0101] The method of the present invention involves locating and defining underutilized or unusable land, with site selection being an important part of the method. Sites that can be selected for this purpose include vacant land, underutilized land, and land that is contiguous with or adjacent to a variety of sites, such as recreational, educational, sports, and commercial sites.

[0102] Recreational, educational, sports, and commercial sites with contiguous underutilized land include event arenas, amusement parks, water parks, museums, stadiums, golf courses, membership clubs, zoos, aquariums, shopping centers, college campuses, casinos, cruise ports, race tracks, horse racing tracks, Olympic venues, etc.

[0103] The site of the method of the present invention should preferably have a minimum area of ​​16,000 m2 and be strategically located to have a population of at least 500,000 within a 50 mile radius around it in order to create a publicly accessible urban beach recreation complex.

[0104] As seen in Figure 7, an exemplary population density map is shown whereby desired areas for vacant and / or underutilized land locations may be identified by analyzing population density within a 50 mile radius surrounding potential vacant and / or underutilized land 21. Figure 7 illustrates population density through different color and / or pattern intensities within the image, with selected locations surrounded by a dashed circle representing a 50 mile radius, and a population analysis was performed to identify the population density of such areas as being at least 500,000 people.

[0105] The urban beach entertainment complexes and the efficient use of limited land use according to the present invention aim to bring new ways of living and transform urban centers into 21st century gathering places, transforming nearby populous urban centers and offering them the possibility to immerse themselves in a tropical lifestyle close to home. These urban centers target the surrounding population and encourage them to return to the urban beach entertainment complexes again and again to have a positive experience, shop, participate in cultural activities, watch movies, practice water sports, have lunch or dinner, sip coffee, and other activities. The creation of such complexes will have a significant impact as it is intended to attract a large number of people to such urban beach entertainment complexes.

[0106] Some prophetic embodiments of how some of the above sites can be efficiently utilized by the present invention are shown in Figures 8A, 8B, 9A, 9B, 10A, and 10B. Figures 8A and 8B show one embodiment of the present invention, in which a horse racing track has a large underutilized area inside the track 21a. The underutilized area shown in Figure 8A is transformed into a beautiful area with a beautiful, clear tropical lagoon 2 as a centerpiece, and an urban beach entertainment complex 1 is created, as shown in Figure 8B. Figures 9A, 9B, and 10A, 10B show another embodiment of the present invention, in which a portion of the parking lot 21b shown in Figures 9A and 10A is transformed into an urban beach entertainment complex with a beautiful, clear tropical lagoon 2 as a centerpiece, in Figures 9B and 10B.

[0107] It is recognized that access infrastructure such as roads and public transport must be provided to transport visitors to the complex (i.e., to enable them to reach the complex in a reasonable amount of time and at a reasonable cost).

[0108] In addition, the site may preferably have a given water source and sufficient availability. The type of water may be fresh, brackish, salt, or marine, depending on availability. The water source may be selected from the group including ocean, groundwater, tap water, surface water, well, or others.

[0109] The water source should not be contaminated with industrial residues that require extensive industrial pretreatment and cannot be removed by simple conventional pretreatment methods such as oxidation or filtration processes. For example, the water source should preferably not be contaminated with industrial water residues such as aluminum or hydrocarbons. Extensive industrial pretreatment systems usually require the use of large settling tanks, which also create an industrial appearance and are counter to the tropical beach impression that is the objective of the present invention.

[0110] Once a site has been selected, the method provides for the development of a publicly accessible urban beach entertainment complex 1 having as its centerpiece a large man-made tropical-style beautiful, clear lagoon 2. The lagoon 2 preferably has the look and feel of a tropical ocean and beach, thereby creating the impression of an elegant beach. By tropical look and feel, it is meant providing the feeling of being in an elegant environment, with a large body of water and sandy beach area, for example, emulating the feeling of being in the Caribbean.

[0111] The publicly accessible urban beach recreational complex includes a low-cost treatment system that provides a water treatment technology that uses at least 50% less electricity than a conventional centralized filtration system for a swimming pool. The water treatment technology includes a filtration system having a capacity and filtered water volume that is at least 50% less than that of a conventional swimming pool filtration system (e.g., filtering the entire volume of water four times per day). Additionally, in an embodiment of the present invention, the water treatment technology for operating the centerpiece tropical lagoon must use at least 50% less chemicals than a conventional swimming pool disinfection system (e.g., must permanently maintain at least 1 ppm chlorine throughout the entire volume of water). Thus, the lagoon 2 has less chemical odor than a conventional pool.

[0112] The urban beach entertainment complex may be located, for example, within a park, however, physical barriers and / or enclosures, such as a control system and access control station 13, must be present to control public access to the urban beach entertainment complex 1 or portions thereof.

[0113] Additionally, to efficiently use limited use sites, facilities, or land, the method includes charging an entrance fee to allow access to at least a portion of the urban beach entertainment complex. Such a fee may be charged prior to visiting the urban beach entertainment complex or may be charged locally based on availability and other factors such as demand, overall occupancy, etc. The fee may vary by age, group size, season, or otherwise. Additionally, the fees may be based on various seasonal, monthly, weekly, or other passes. It will also be appreciated that electronic tickets using cell phones and other devices may be used in addition to printed ones and / or cards. It will also be appreciated that there may be seasonal passes (such as weekly, monthly, or annual passes) that may be purchased online or prior to visiting the urban beach entertainment complex.

[0114] In embodiments of the invention, the centerpiece lagoon and surrounding facilities are accessible only after payment of an entrance fee that is collected prior to entry. However, in some embodiments, it may be desirable to allow guests to use at least a portion of the entertainment, cafe, and restaurant areas without paying a fee. In those embodiments, users of the beach and water sports areas may be charged a fee to access those areas.

[0115] Thus, the method includes an opportunity to generate revenue on underutilized or currently unused land, such as vacant land, land with limited use, and land contiguous with or adjacent to recreational, educational, sports, and commercial sites, by creating a novel beach entertainment complex with as its centerpiece a large, beautiful, clear, tropical-style lagoon, where access is controlled and tickets / fees are charged for admission.

[0116] Based on the population within a 50 mile radius and the amount of demand generated by the urban beach entertainment complex, it is anticipated that at least 100,000 visitors per year, preferably 500,000 visitors per year, and most preferably over 1,000,000 visitors per year will have access to the tropical-inspired environment. Visitors are anticipated and targeted primarily to be from the surrounding population and are expected to visit the urban beach entertainment complex multiple times. Due to the beautiful and recreational nature of these beach-like environments, where activities such as relaxation, shopping, water sports, swimming, and dining can be enjoyed, the annual visitation is expected to be large, with a large percentage of nearby residents and an additional percentage of tourists visiting the publicly accessible urban beach entertainment complex.

[0117] It is estimated that by creating a complex utilizing the principles of the present invention, visitor numbers for such an urban beach entertainment complex may achieve on the order of 100,000 to 1,000,000 admissions and up to 6,000,000 visitors per year. Based on the market and socio-economic conditions of the city, admission fees are expected to range from USD$5 to USD$150, preferably USD$10 to USD$20, with direct annual revenues of USD$1,000,000 to USD$120,000,000 from admission tickets alone.

[0118] So, for example, if the scale is 16,000m 2An urban beach entertainment complex with a tropical-style centerpiece lagoon, 500,000 visitors per year, and an entrance fee of US$15 could generate direct ticket revenues of US$7,500,000, in which case the total construction costs of the centerpiece lagoon would be around US$2,400,000, and the annual operating costs would be less than US$100,000 per year (taking into account chemicals and electricity).

[0119] V. Shopping Mall Example As another prophetic example, it should be noted that the method of the present invention can also be used in the shopping mall industry, where a portion of a parking lot within a currently underutilized shopping mall space can be converted into an urban beach entertainment complex. Three scenarios were derived from the project evaluation, including a conservative scenario, a standard scenario, and an upside scenario, and the revenues and profits associated with building, operating, and charging admission to an urban beach entertainment complex are shown in Table 3 below.

[0120] [Table 6]

[0121] The scenarios shown in Table 3 do not consider event centers, large restaurant areas, or sports venues, but do consider ancillary facilities such as beach centers with rental shops. Therefore, the profit margins are expected to reach a fairly high level, thereby creating a very attractive market and investment by increasing the efficiency of land with limited uses, in this case the current shopping mall parking lot.

[0122] It is important to note that several locations around the world have been improved, for example by adding sand to the borders of natural rivers with poor water quality. These improvements alone attract over 500,000 people annually. Examples of such locations include Lujan Beach in Mendoza, Argentina and Encarnacion in Paraguay. However, neither of these two examples of publicly accessible locations have been transformed into a 21st century gathering place with ancillary facilities in an urban beach entertainment complex with a beautiful, clear tropical lagoon as its centerpiece, a beach center, rental stores, a stage, and similar facilities and amenities for day and night enjoyment with family and friends. Furthermore, such locations are not believed to have the opportunity for a profitability as high as that of the method of the present invention, where calculations and economic evaluations have shown an internal rate of return of up to 172% and even more depending on the specific scenario. The ability to cost-effectively transform limited-use land, such as underutilized land or facilities adjacent to or adjacent to recreational, educational, sports, or commercial sites, into profitable operations by creating an urban beach recreational complex is unprecedented and would have significant social and economic benefits.

[0123] The urban beach entertainment complex and method of the present invention for providing efficient utilization of limited land use also contemplates the inclusion of recreational and commercial amenities within the urban beach entertainment complex through the rental or provision of space, facilities, food and beverage or other services, activities, or equipment. Thus, according to the study, it is expected that the revenue from direct admission fees calculated above can even be doubled through such ancillary businesses.

[0124] Surrounding the tropical centrepiece of the resort is a beautiful, clear lagoon, some of the amenities include: -A natural beachfront amphitheater with a stage and space for concerts, e-sports, etc. -Large screens for showing movies, sporting events, conferences, educational activities, live events, exclusive streaming of shows and other events, etc. -A unique waterfront event centre and venue for meetings, weddings, trade shows, fairs, conferences etc. - Food and beverage sector with permanent or temporary establishments such as bars, restaurants, food trucks, coffee shops etc. -Sports sector including gyms, running tracks, soccer fields, tennis courts etc. -Shopping centres and facilities -stand - Activity reception or rental center for equipment rental

[0125] Within the urban beach entertainment complex, an amphitheater section 17a may also be created, which may accommodate a large screen 17b and / or a stage 17c, thereby accommodating areas for a variety of activities (see FIG. 1).

[0126] Other activities that can be carried out directly or indirectly using the large tropical-style beautiful, clear lagoon are floating water parks including Wibit® or Aquaglide® facilities, banana boards, holographic light displays, water shows, floating stages, etc.

[0127] A variety of activities and shows can be performed live on-site or displayed and / or streamed through large screens configured to be viewed by a given number of people, including concerts, water ski shows, drone light shows, aqua climb shows, synchronized swimming, ceremonies, shows such as movies, TV series, documentaries, sports including beach volleyball, e-sports, games and gaming activities, competitions including drone racing, streaming of live or pre-recorded material, etc.

[0128] A beach entertainment complex may be mostly outdoors or may be completely or partially covered with a dome or structure that allows for year-round use and activities in a seasonal location and allows for winter events within the dome. Such domes may be structural or inflatable and may be positioned and configured to cover all or part of a tropical lagoon.

[0129] Other amenities that may be configured within a beach entertainment complex include beach cabanas, bars, retail stores, waterfront or beachfront terraces, restaurants, food trucks, picnic and BBQ areas.

[0130] In an embodiment of the invention, the focal point, the beautiful clear lagoon 2, is heated partially or completely through an external heating system that utilizes waste heat from an industrial process. For example, the beautiful clear lagoon may be heated indirectly using a heat exchanger that exchanges warm water from the cooling stage of the industrial or commercial process with water from the beautiful clear lagoon. Warming may occur through a heating system (not shown), such as a heat exchanger, that indirectly transfers heat from the cooling stage of the industrial or commercial process to the lagoon water.

[0131] In another embodiment of the invention, the bathing zone of a tropical artificial lagoon is heated through a heating system that heats the zero entry beach edge of the lagoon, allowing for a higher water temperature in the bathing area.

[0132] In other embodiments of the invention, make-up water is returned to bathing zones to control the temperature of the water in such bathing zones, particularly in hot climate locations where the make-up water is typically cooler than the main lagoon water and such make-up water therefore serves to lower the temperature of such zones.

[0133] Other devices may be included around or within the focal lagoon to generate water surface texture and movement in the form of aesthetic waves, the aesthetic waves having amplitudes not exceeding 50 cm in most parts of the lagoon.

[0134] VI. Alternative Embodiments 1 and 8A, 8B, 9A, 9B, 10A, 10B show a plan view or aerial view of a schematic configuration of a first embodiment of an urban beach entertainment complex 1, in which the entire urban beach entertainment complex 1 is physically enclosed through a physical barrier 16, which may have at least one access control station 13 that allows access to the urban beach entertainment complex 1. A clear and beautiful central lagoon 2 has at least one zero-entry beach edge 3a and a sandy beach area 6 that surrounds at least a portion of the central lagoon. An amphitheater 17a may also be included in the urban beach entertainment complex, facing the clear and beautiful central lagoon 2, which may provide a venue for various entertainment events and may also include a large screen 17b. The urban beach entertainment complex also includes various recreational, educational and commercial sites and facilities 17, such as an event center 17d, which may be temporary or permanent.

[0135] While the present invention has been particularly shown and described with respect to preferred embodiments thereof, it will be apparent to those skilled in the art that various other changes in form and detail may be made therein without departing from the spirit and scope of the invention.
