FIELD OF THE INVENTION

The présent invention relates generally to a venue transformation and construction method for creating a public access tropical style swimming lagoon at the centerfield of racing and/or activity circuits, for swimming and the practice of water sports, whereîn a portion of the infield of such racing and/or activity circuits is démolished in order to generate a swimming lagoon. There is at least an area of the tropical style swimming lagoon where public access is controlled, and a beach area is preferably located within the controlled access area.

BACKGROUND OF THE INVENTION

Although once a booming market, over the years the growth of race and/or activity circuits such as horse race tracks, speedways, athletic courses, among other installations has stopped and is sometimes even declining or has limited uses, one reason being the lack of innovation and additional amenities and features présent at these facilities.

In the case of horse race tracks, it has been estimated that its market size for 2019 is USD$3.8 billion (IbisWorld, 2004), with a steady décliné tendency of-0.6% per year on average over the last five years. The U.S. alone has more than 75 horse race tracks (WorklCasinoIndex, 2019), and more than 250 worldwide, representing an interesting market to develop and promote new uses and innovations.

In the case of motor race tracks, there are many types such as dirt tracks, paved ovals, and speedways. Dirt track racing is one of the most commun types of auto racing in the U. S., and according to the National Speedway Directory there are more than 700 dirt oval tracks in the U.S. (SpeedwayDirectory, 2019). On the other hand, paved tracks are also used for racing, commonly referred to as speedways, and hâve different shapes but always having a center location where the racing circuit has an oval like shape.

Generally, these types of facilîties are only used during planned events and races during the day, not usually being able to use them every day or at nighttime, which means that there is a lot of ‘dead” times where the facilîties are not utilized and therefore they hâve a very high opportunity cost.

For horse race tracks, for example, generally the races are held once or twice a week, mostly over the weekend, and some facilîties hâve races during a few months of the year and not throughout the year due. For motor race tracks and speedways, it is very similar with motoi laces being held a few times per week at most. Athletic circuits are even less întensively used, with athletic races or compétitions being generally held a few times per month.

However, it’s important to mention that even when these facilîties are holding an event, there are areas such as the infield area that are not usually utilized for other puiposes. Spectators and visitors generally concentrate on the outside borders of the race track and the infield and center of the track does not hold other major activities.

On the other hand, ail of these types of facilîties hâve been designed, built, and permitted in order to house a large number of people and visitors, having the proper amount of parking spaces, road connections, restroom facilîties, and other installations that allow holding massive events and gatherings. In addition, most of these facilîties are located in or close to urban locations, or that are easily accessed by large numbers of people. It is important to highlight tirât the look of these types of facilîties is very similar and generally tends to move îoward rough concrète and artifîcial looking structures, not being aesthetîcally pleasant for visitors.

Therefore, one wonders why ail of these locations that are already designed and built to house massive amounts of people are so underutilized, being used a few times per week or per season but already having ail the infrastructure needed to operate every day if necessary. There is a poor

I utilization of urban spaces, with facilities that are able to congregate large amounts of people and that hâve prime locations easily accessed by visitors not being used more often.

In addition to this poor use of well-connected urban spaces with infrastiuctuie to hold large events and gatherings, there ha s been an explosive increase in worldwide tourism ovei the yeais that has substantially increased its carbon foorprint (See FIG. 1 that shows the increase of tourists over the years). This is mai ni y because people hâve to travel long distances and use theii car, oi hâve to tly, or use other transport means to be able to reach wateriront settings and beach areas, sometimes having to travel hundreds of miles to be a part of a beautiful waterfront beach setting, in resuit having a very large carbon footprint due to ali of this movement. This is especially relevant today, where society has beconte very aware ofcarbon lootprint, where travel is one ofthe big contiibutois of carbon émissions.

Finally, it’s important to note that urban locations are very hectic and stressful and urban population has increasing demands for open recreational spaces where they can relax, practice sports, and enjoy of beautiful scenery and spaces. Congrégation spaces are scarce, and the old tradition of congregating in shopping malls or retail facilities has shifted into a search foi open and natural settings.

Therefore, as it has been mentioned before, there are many of these types of racetrack facilities that hâve already built infrastructure to hold large numbers of people, but that hâve limited uses or are only used during programmed events, that hâve poor aesthetics, and that only offei their visitors with very limited activities and amenities.

DETAILED DESCRIPTION OF THE INVENTION

The method from the présent invention, as seen in FIG. 3, allows to, in an innovative way, transform race tracks and zones within race tracks located in urban areas with good connectivity, which currently hâve very few uses, in order to provide beautifol tropical-style beach-ltke settings in front of a crystal clear lagoon that can help solving the need for more récréâtional urban open air spaces and tourism needs with a lower carbon footprint and thereiore become a completely new and ladical trend that can change the lifestyle of people around the world.

The présent invention relates general 1 y to a venue transformation and construction method tor creating a controlled access tropical style swimming lagoon with crystal clear turquoise waters and beaches at the centerfield of racing and/or activity circuits, for swimming and the practice of water sports, wherein a portion of the infield of such racing and/or activity circuits is demolished in otdei to generate a swimming lagoon accordîng to designs, construction parameters and configurations. There is at least an area ofthe tropical style swimming lagoon where public access is controlled, and a beach area is preferably located within the controlled access area.

As used herein, tropical-style refers to clear water lagoons with round shapes, that are suitable foidirect contact recreational purposes, and that usually hâve turquoise colored crystal clear waters and do not hâve visible macro algae presence or a green water tonality like artificial lagoons and lakes located in parks and golf courses, among others.

The présent invention aims to improve the aesthetics and provide new uses to race and/or activity circuits such as horse race tracks, speedways, athletic courses, in order to allow such facilities to be used over larger periods of time and/or periodically compared to carrent uses of once or twice per week.

One important and common feature ail of these facilities hâve is the presence of a large infield that is located in the center location of the facility, being surrounded by the racing circuit. At the same time, current worldwide trends indicate that people are more and more looking for outdoor activities that can transport them into beautiful natural iandscapes and scenery, where being in tropical sandy beaches and waterfront sceneries are one of the top expériences.

As such, the présent invention discloses a venue transformation and construction method for creating a tropical style swimming lagoon with beaches in the centerfield of race or activity circuits which aims to repurpose the infield of such circuits by creating a recreational venue with at least one swimming lagoon and additional amenities. In a preferred embodiment of the invention, the recreational venue includes a number of recreational amenities, and may include a swimming area within the swimming lagoon with at least one beach located in its perimeter.

As used herein, race or activity circuits refer to any motor, animal, or athletic race tracks or circuits such as for auto, karts, motorcycles, trucks, horses, and dog racing as well as for track and field athletic events.

As used herein, infield site refers to the land comprised in the inncr location of a race or activity 5 circuit.

Typically, the infield site does not hâve tall construction installations or structures, as such sites should not significantly block the view of visitors attending the race or activity ciicuit installation. Therefore, an infield site must be provided in order to plan and coordinate the démolition process and the construction of the tropical style swimming lagoon. The infield site is located within the 10 racing/activity circuit perimeter.

In more detail, the demolishing process comprises excavating at least a portion of the infield site to excavate a layer of between 15 cm to 6 meters in order to provide the necessary excavated volume for the swimming lagoon construction. To provide clarity, for the purposes of this application the terra demolishing encompasses not only knocking down or tearing down current structures or 15 installations, but also removing débris or non-fixed materials from such zone and digging or excavating a portion of the land as part of the construction method.

Optionally, if there are permanent or rigid structures within the infield site, démolition can be performed of such structures to allow excavation necessary to build the swimming lagoon.

The démolition process comprises excavation with machinery up to a depth of 20 centimeters over 20 the final excavation level, where the final 20 cm may be excavated manually.

Once the design excavation level is achieved, the bottom soi! must be compacted to achieve a 95% Modified Procter Density. A 95% Modified Procter Densîty means that the soil at the bottom is compacted to 95% of its maximum dry density. This aims to reduce post-construction settlements rates of such soil. As a reference, the Modified Procter test uses a 4-inch-diameter mold which holds 25 1/30 cubic feet of soil, and uses a 10 1b. hammer falling through 18 inches, with 25 blows on each of five lifts, for a compaction effort of about 56,250 ft-lb/ft3. This can also be explained such that the bottom of the excavations are to be compacted to a 95% of the Maximum Dry Compacted Density, based on the Modified Proctor test (ASTM D1557-02) when the soil type has more than a 12% material passing under a N°200 mesh (opening of 0.075 mm). When the soil type has less than a

12% material passing under a N°200 mesh (opening of 0.075 mm), the soil must be compacted to achieve no less than 80% of its Relative Density.

The process also includes excavating a volume of at least 4,000 m3, preferably at least 7,000 m3 from an area within the infield site. This excavation material preferably will serve as the earthworks necessary to provide the basin of the swimming lagoon, wherein such earthworks are created within the property perimeter, and wherein the basin includes a basin perimeter and a bottom. It will be appreciated by those of skill in the art that the excavated material may prove to be unsuitabie for the earthworks. For ex amp le the material may include a mixture of rocks, cernent, tar or other détritus. In such an event, suitable fill and other materials may be brought to the site for the earthworks.

The basin for the lagoon is designed and constmcted so that its surface area is at least 3,000 m2, preferably at least 5,000 m2, more preferably at least 10,000 m2, and most preferably at least 15,000 m2 and its deepest point has a minimum depth of 1.4 meters. As a reference, most infields of racetracks hâve between 2 - 20 hectares, with some of the large racetracks of the world having for example 16 hectares at their infield (For example, Meydan Racecourse in Dubai).

It’s important to highlight that for the swimming lagoon of the présent invention, sînce it has a surface larger than 3,000 m2, conventional swimming pool construction technologies are seldom economically and technically feasible, as for example swimming pool construction requires to hâve a large and thick concrète structure that comprises a sériés of inlets and outlets within the walls and bottom of the structure in order to be able to create water movement and circulation that allows to filter the complété water volume at least once per day. This is maînly to hâve a homogeneous water body so that when withdrawing and filtering the water flow means that the whole water volume is being iïltered and there are no dead areas that hâve no water circulation and would therefore not be filtered efficiently.

For example, régulations for swimming pools around the world require the use of bottom and/or wall nozzles, wherein régulations preferably require the use of bottom inlets to be able to generate proper mixing and circulation of water before it is wîthdrawn from the pool to send to the filtration System. For example, Florida’s swimming pool construction régulations require that inlets be installed so that spacing between floor inlets does not exceed 20 ft. (6 m) and the distance between a bottom inlet and a wall does not exceed 10 ft. (3 m). This means that a 25 m x 50 m Olympîc pool for example would require more than 35 bottom inlets, and a 3,000 m2 (60 m x 60 m) swimming pool would require more than 70 bottom inlets, in addition to wall inlets that would further allow mixing the water volume so that when withdrawing water from the main drains, sk immers, or other withdrawal points and sending such water to the filtration System, it effectively allows to filter the complété water volume of the pool from 1 to 6 limes per day (generally 4 fîmes per day based on régulations). The présent invention preferably requîtes that the swimming lagoon has at least 50% less inlets than those required for the filtration System of a conventional swimming pool according to swimming pool standards. As a comparison, for a lagoon of 15,000 m2 of surface ( 150 x 100), the number of bottom inlets would be more than 350.

Containment walls are preferably constructed on at least one section of the basin perimetet, as to form a waterfront perimeter that is arranged and configured to contain the water within the basin. Such containment walls require a backfill material in order to provide structural integrity to such walls.

In addition, a sloped area is preferably constructed in at least one section of the basin perimeter in order to create a beach access perimeter. The sloped area is constructed such that the slope of the beach access perimeter is between 5% and 30%. The sloped area may require construction or placement of a support slab in order to provide structural stability on such location. As an example, a support slab can be built out of reinforced concrète, shotcrete, plastics, or other support materials. For example, the sloped area may hâve high foot traffic of users accessing the swimming lagoon.

The shape of the waterfront perimeter is preferably curved to create a more natural aspect of the swimming lagoon with a tropical style. Additionally, the basin has a maximum width of 300 meters at its widest point. The width of the lagoon is defmed as the measurement or extent of the lagoon from side to side; the lesser of the two dimensions of the lagoon measurements. The length of the lagoon is defmed as the largest dimensional measurement of the lagoon.

The maximum width of the lagoon is limited in up to 300 meters, as there is little visual impact to be gained at eye level with larger distances.

The bottom of the basin is covered with a non-permeable material, in order to act as a water containment structure. The non-permeable bottom material that covers the bottom of the basin comprises plastic liners, shotcrete, or flexible materials that do not require the use of a thick concrète layer like conventional swimming pools. The use of vast surfaces of thick concrète is problematic, as in addition of having high costs, it can généra te structural tensions that cause fractures, cracks, settlements in the concrète and may impact the structural properties of the basin.

In a preferred embodîment, the nompenneable material comprises a plastic liner of at least I mm of thickness, among other solutions. The plastic liner can hâve different colors and tonalities, but preferably it has a white, blue or light color which provides an intense turquoise tonality of the waîer body.

The swimming lagoon is built in order to provide a new and innovative amenity that allows aeneratîng a completel y new user expérience in race or activîty circuit sites. Embodiments heiein are directed to a swimming lagoon that is arranged and configured to optimize visitor expérience. Specifically, the lagoon is arranged and configured in a way such that the relationship between ail éléments and purposes of the different areas of the lagoon enable guests and visitors to enjoy the expérience as well as interact with the different areas that may be designated for different puiposes. A beach area included in the swimming lagoon is preferred. However, there may be instances when a sloped beach access with a swimming area is impractical or is otherwise not desired for the spécifie site.

Further, the swimming lagoon is also preferably constructed in a manner so that it can be used not only for swimming puiposes, but also for the practice of several waîer sports, such as kayaking, stand-up-paddling, boatîng, water skiing, among others and also providing a spectacular view of a turquoise crystal clear lagoon from the spectator area of the race track.

Although the swimming lagoon is mammade, it preferably includes shapes that tend to imitate natural geometries, and comprises a slightly elongated shape to provide visitors with at least one vantage point to expérience dramatic views of the lagoon and its surroundings.

Additionally, the tropical style swimming lagoon comprises different éléments and areas for providing an optimized visitor expérience, preferably including at least one controlled access area. This is achieved by constructing one or more barriers around the basin perimeter of the swimming lagoon, in order to cordon off an area of the swimming lagoon to establish a controlled access area with a restricted access swimming lagoon located within. In that case, the controlled access area includes at least one beach access perimeter within the basin perimeter, thereby providing a new recreational amenity and venue for visitors. The barriers comprise at least one access point to selectively allow users into the controlled access area. The remaîning area about the basin perimeter can optionally be an open access area, meaning that is a non-ticketed area, that is freely accessed by users. However, the controlled access area preferably requîtes a ticket, voucher or other payment of an entry fee for accessing such area which can be included within other fees or payments for example access can be included in seasonal tickets, or by being member of an association oi group, being inclnded as part of lodging facilities, among olhers.

Contre lied acc ess areas may be created about the swimming lagoon for other purposes as well. However, in the case there are non-ticketed areas, it is important to include separate access points for both contre lied access areas and non-ticketed access areas ot the lagoon. This enables visitons to clearly participais in either one or both areas depending on their purpose for visîting the race/activity circuit facîlity and its infield site and lagoon. including natural articulations and man-made focal points along the edge to encourage walkabilîty and toster visitors with a sense of discovery. The swimming lagoon can be ilhiminated through a lighting System, in order to allow nighttime uses and hâve spectacular views from the spectator areas. The lighting System comprises exterior lighting Systems and/or imderwater Systems.

As previously mentioned, it is preferred that the lagoon include ai least one controlled access area for visitors for at least one beach area, wherein the beach area comprises a sandy beach and sloped transition into the swimming lagoon. The controlled access area may be designed such that the total beach area to lagoon area ratio is 1 :2. Further, the beach area is preferably placed and designed considering general summer sun orientation, optimizing visiter expérience. In another embodiment of the invention, the controlled access area surrounds the entire lagoon surface, and may include additional amenities within the controlled access area, such as recreational facilities including cafés, bars, restaurants, and others.

In another embodiment of the invention the construction of an ampliitheater in the surroundings of the lagoon and nearby the beach area(s) is also preferred. This créâtes an opportunity to hold events such as concerts and festivals, among others in a unique setting. Other actîvities include music on the beach, dining on the beach, and other events on the beach such as weddings and sports events, among many others. The surroundings of the beach may include cafés, bars, restaurants, beach centers, promenades, hôtels, entertainment facilities, virtual and immersîve expériences, and similar facilities and amenities.

In the case of having a non-ticketed area within the venue, the at least one non-ticketed access area comprises optimized waterfront perimeter surrounding the swimming lagoon that has an unobstructed view of the lagoon and is not dîrectly in front of any beach areas or esplanades that could affect the aesthetîcs of the landscape. The non-ticketed access area comprises restaurants, cafés, stores, bars, and similar facilities in its surroundings.

A screen may also be provided in the vîcinity of the swimming lagoon to broadcast content and house events and shows, and can be located in the same sector as the amphitheaters, to créât e a new event venue having the swimming lagoon as its backdrop.

Such screen can be fixed or may be removable and not permanent as to avoid creating obstructions to the race circuit during races or events, and can otherwise be used lor othei times when racing events or activities are not held. The screen may also be used for streaming live or recorded events or general media, and the stage zone can be used to broadcast or hold e-sport compétitions, conceits, plays, shows, performances, aniong others.

In an embodiment of the invention, the installations suiTounding the tropical-style lagoon is artificially set with a beach theme, including the use of blue and white colors with the inspiration of the beach and beach kiosks and lighthouses.

It is important to highlight that some features such as screens, amphitheaters, kiosks, or other facilities built or installed in the surroundings of the tropical style lagoon should not interfère significantly with the view of spectators. The swimming lagoon can also be surrounded by végétation such as plants and trees.

The method of the présent invention also includes a connection path in order to allow transit of vehicles and people from one side to the other without obstructing the racing and/or activity circuit. Such connection path can include constructing a tunnel structure that connecta the outfield of the racing and/or activity circuit with the infield site, or a bridge structure, the racing circuit can be designed to accommodate the passing of people and vehicles from one side ofthe racing track to the other during non-race times, or any other form that allows the passing of people and/or vehicles.

Accordingly, other components that embody the principles of this invention can be configured within the spirit and intent of this invention. The arrangement described herein is provided as only one example of an embodiment that incorporâtes and practices the principles of this invention. Other modifications and alterations are well within the knowledge of those skilled in the art and are to be included within the broad scope of the appended daims.
