To the extent appropriate, priority is claimed to all of the above-disclosed applications. Technical Field

[0003] This invention relates to an urban redevelopment and construction method for building a tropical-style swimming lagoon for public use on vacant or abandoned sites. The lagoon contains clear water for swimming and water sports practice, wherein a portion of the vacant site is demolished to form the swimming lagoon. Preferably, the swimming lagoon includes at least one controlled public use area, and a beach area is located within this controlled use area. Background Technology

[0004] Around the world, as cities and urban spaces continue to grow, many vacant and / or abandoned sites are left between all these urban development projects, which may be left vacant or abandoned due to limited use.

[0005] For reference, it is estimated that on average, 15% of land in a U.S. city is considered vacant, encompassing various land types, from undisturbed open space to contaminated abandoned brownfield sites (Pagano et al., 2000). This is particularly true in Southern cities, where over 19% of land is considered vacant, primarily due to high levels of population and land area growth. Along with urban expansion, many lots and spaces remain undeveloped and ultimately become vacant. The average available vacant land area in U.S. cities is 12,367 acres, with a median of 4,499 acres.

[0006] Generally, vacant lots are associated with declining property values, crime, litter, abandonment, poor landscaping, and widespread economic and / or social decay, leading to a very negative perception of vacant lots. Vacant lots can severely damage neighborhoods, impair the quality of life for neighbors, reduce the value of nearby properties, and decrease local tax revenue. Studies have shown that vacant and abandoned properties increase crime rates and lower property values; furthermore, their repair or demolition (for abandoned structures) is costly and must be borne by the city.

[0007] Some vacant land sites are those that have been planned for the construction of parks, classified as open-air recreational areas or green spaces, but have not yet been developed, resulting in abandoned and neglected sites. In addition to vacant land in the strict sense, green spaces (such as underutilized or poorly maintained parks) can also be considered relatively vacant land because they have the same negative impact on the community.

[0008] Research indicates that the reuse of vacant land and abandoned buildings can represent opportunities for economic growth and revitalization in various urban areas. This applies to all cities, regardless of population or city size.

[0009] As used herein, vacant and / or abandoned sites refer to sites and / or lots that are not only vacant or have abandoned buildings, but also include parks or lots with limited uses or sites with building restrictions. For example, this may represent green spaces for underutilized private projects, land where high-rise buildings or high-rises are not permitted, lots with very low use density, or land requiring lengthy permitting and approval processes to be converted into real estate or commercial projects.

[0010] For example, thousands of abandoned and / or vacant sites have been transformed into community gardens and parks. This relative trend of “greening” includes converting vacant land into environmentally friendly green spaces, ultimately serving as community gardens and woodlands. The conversion of vacant land can provide more green space for urban landscaping and recreation, as well as other urban regeneration purposes.

[0011] For many years, the demand for these types of green spaces has been growing, coinciding with a growing population in urban areas. This creates a need for open-air locations that provide relaxation and recreational activities such as jogging and exercise. Generally, these green spaces also have positive impacts on the surrounding environment, such as increasing the value of nearby real estate, developing new markets (e.g., commercial development near parks), and improving the health and environmental benefits of users—the complete opposite of the negative impacts of vacant or abandoned sites.

[0012] Rapidly developing and highly densely populated cities can greatly benefit from the redevelopment of such vacant or abandoned sites, especially since these cities have few opportunities to develop new green spaces through other means. However, efforts to transform vacant or abandoned sites into community spaces have not made significant progress, failing to utilize these underutilized spaces to improve the quality of urban life and positively impact the environment. Many redevelopment alternatives, including gardens and similar sites, have not been very successful, and a large number of vacant and / or abandoned sites remain worldwide.

[0013] The stress and urban lifestyle of big cities have a significant impact on people, leading them to seek different environments and lifestyles to relax. Importantly, the global tourism industry has experienced explosive growth over the years, resulting in a significant increase in its carbon footprint (see Figure 01, showing the increase in visitors over the years). This is primarily because people must travel long distances and use their cars, planes, or other means of transportation to reach waterfront areas and beaches, sometimes trekking hundreds of miles to reach a beautiful waterfront location, resulting in a substantial carbon footprint from all such travel. This is particularly important today, as society is increasingly focused on carbon footprints, with tourism being one of the major contributors to carbon emissions.

[0014] In busy and stressful urban environments, the demand for open-air recreational spaces is constantly growing, where people can relax, exercise, and enjoy beautiful scenery and open spaces. Spaces available for gathering are scarce, and the old tradition of crowds congregating in shopping malls or retail facilities has shifted to seeking out natural, open-air environments.

[0015] Therefore, there are currently many vacant and / or abandoned spaces that are misused or have limited uses. These spaces are in relatively well-connected urban locations but lack the aesthetic features that people would like to see, such as recreational uses and a beautiful environment. Summary of the Invention

[0016] Therefore, according to one embodiment, an urban redevelopment method is provided for constructing a tropical-style swimming lagoon with sloping access on a vacant and / or abandoned site, the method comprising: demolishing at least a portion of the vacant or abandoned site, wherein the demolition process includes excavating layers of at least 15 cm to 6 m; and excavating from an area within the site having a depth of at least 4,000 m. 3 Material of volume; forming for a surface area of ​​at least 3,000 m² 2The basin comprises a large body of water with a minimum depth of at least 1.4 meters at its deepest point, wherein earthworks for the basin are constructed within the perimeter of the surrounding site, and wherein the basin includes a basin perimeter and a bottom; a water-retaining wall is constructed on at least a section of the basin perimeter to form a waterfront perimeter, wherein the shape of the waterfront perimeter is primarily curved, and the maximum width of the basin is 300 meters; the bottom of the basin is covered with an impermeable material, similar to a conventional swimming pool, without thick concrete; an inclined passageway area is constructed on at least a section of the basin perimeter to form a beach passageway leading to the large body of water; one or more barriers are constructed around the basin perimeter to isolate an area thereby establishing a controlled use area, wherein the controlled use area includes a beach passageway perimeter, and the barriers include at least one entrance point to selectively allow users to enter the controlled use area, thereby allowing users permitted to enter the controlled use area to use the beach passageway; and at least one additional recreational facility is constructed near the waterfront perimeter, including catering and commercial facilities, particularly such as restaurants, bars, kiosks, shops, and cafes.

[0017] These and other variations of the invention will become clear to those skilled in the art after a more detailed description of the invention. The advantages and features characterizing the invention are particularly pointed out in the appended claims, which form part of the invention. However, for a better understanding of the invention, reference should be made to the accompanying drawings, which form part of the invention and illustrate and describe preferred embodiments of the invention.

[0024] like Figure 2 As shown, the method of this invention can innovatively transform vacant or abandoned sites in urban areas, often with good connectivity, into beautiful beach-like layouts. This helps address the need for more recreational urban open spaces and tourism demand with a lower carbon footprint, and thus represents a radical new trend that could potentially change the lifestyles of people around the world. This invention helps address the need for recreational environments and activities that could transform the lifestyles of urban populations worldwide, while also helping to resolve the problems associated with vacant or abandoned sites and their negative impacts on communities.

[0025] This invention relates to an urban redevelopment and construction method for creating a controlled-use tropical-style swimming lagoon on a vacant or abandoned site. The lagoon contains clear water and includes a sandy beach for swimming and water sports practice. Specifically, a portion of the vacant or abandoned site is demolished to form the swimming lagoon, according to design, construction parameters, and construction. Preferably, at least one controlled-use area exists within the swimming lagoon, and the sandy beach area is located within this controlled-use area.

[0026] This invention discloses a construction method for reusing such spaces by constructing a tropical-style swimming lagoon with at least one tropical-style swimming lagoon and additional amenities on vacant or abandoned sites.

[0027] The construction method of the present invention is less expensive than building other facilities such as shopping malls, amusement parks, water parks or similar facilities in the same space.

[0028] As used in this article, tropical style refers to a circular clear water lagoon suitable for direct contact recreational purposes, and typically features clear blue water without visible large algae or the green hues of artificial lagoons and lakes such as those in parks and golf courses.

[0029] More specifically, the process involves excavating at least a portion of an vacant or abandoned site to excavate layers between 15 cm and 6 m in order to provide the necessary excavation volume for the construction of the swimming lagoon.

[0030] Optionally, if there are permanent or rigid structures on the site, particularly in the case of abandoned sites, such structures may be demolished to allow for the necessary excavation for the construction of the swimming lagoon. For clarity, in this patent application, the term "demolition" encompasses not only pushing down or removing existing structures or facilities, but also clearing debris or non-fixed materials from such areas and excavating or digging a portion of the land as part of the construction method.

[0031] The demolition process involves mechanical excavation to a depth of 20 centimeters above the final excavation level, from which the final 20 centimeters can be excavated manually.

[0032] Once the design excavation level is reached, the bottom soil must be compacted to achieve 95% of its modified Proctor density. 95% modified Proctor density means that the soil at the bottom is compacted to 95% of its maximum dry density. This is done to reduce the post-construction settlement rate of this type of soil. For reference, the modified Proctor test uses a 4-inch diameter mold (containing 1 / 30 cubic foot of soil) and a 10-pound hammer, dropped 18 inches, with 25 impacts per lift in five lifts, achieving approximately 56,250 ft-lb / ft³ of compaction work. This can also be interpreted as, based on the modified Proctor test (ASTM D1557-02), when the soil type has more than 12% of the material passing through an N°200 mesh (0.075 mm opening), the bottom of the excavation is compacted to 95% of its maximum dry compaction density. When less than 12% of the material in a soil type passes through an N°200 mesh (0.075 mm opening), the soil must be compacted to achieve a density of not less than 80% of its relative density.

[0033] The process also includes excavating at least 4,000 m from areas within vacant or abandoned sites. 3 Preferably at least 7,000m 3 The volume of the excavated material is specified. This excavated material will preferably be used for earthworks necessary to provide a basin for a swimming lagoon, wherein such earthworks are created within the property perimeter, and wherein the basin includes the basin perimeter and bottom. Those skilled in the art will understand that the excavated material may prove unsuitable for earthworks. For example, the material may include mixtures of rock, cement, tar, or other gravel. In such cases, suitable filler and other materials may be transported to the site for earthworks.

[0034] The basins used for lagoons are preferably designed and constructed such that their surface area is at least 3,000 m². 2 Preferably at least 5,000m 2 And more preferably, exceeding 10,000m 2 Furthermore, the minimum depth of its deepest point is 1.4 meters.

[0035] An important point to emphasize is that, for the tropical-style swimming lagoon of this invention, since its surface area is greater than 3,000 m... 2 Traditional pool construction techniques are not economically or technically feasible because, for example, pool construction requires large and thick concrete structures, including a series of inlets and outlets located within the walls and bottom of the structure, to create water movement and circulation that allows the entire volume of water to be filtered at least once a day. This is primarily to obtain a uniform water body so that when water is pumped and filtered, it means that the entire volume of water is being filtered, and there are no dead zones where water does not circulate and therefore cannot be effectively filtered.

[0036] For example, pool codes around the world require the use of bottom and / or wall nozzles, with codes preferably requiring bottom inlets to enable proper water mixing and circulation before water is drawn from the pool and delivered to the filtration system. For instance, Florida pool construction codes require inlets to be installed such that the spacing between floor inlets does not exceed 20 ft (6 m) and the distance between bottom inlets and walls does not exceed 10 ft (3 m). This means that, in addition to wall inlets, a 25m x 50m Olympic pool would require more than 35 bottom inlets, and a 3,000m... 2 A 60m x 60m swimming pool will require more than 70 bottom inlets, which will further allow for mixing water volumes, enabling the entire volume of the pool to be effectively filtered 1 to 6 times per day (typically 4 times per day according to regulations) when water is pumped from the main drain, skimmer, or other intake points and sent to the filtration system. Preferably, this invention requires that, according to pool standards, the swimming lagoon have at least 50% fewer inlets than the filtration system required for a conventional swimming pool.

[0037] The wall is preferably constructed on at least a section of the basin perimeter to form a waterfront perimeter arranged and constructed to enclose water within the basin. Such a wall requires backfill material to provide structural integrity.

[0038] Furthermore, the sloping area is preferably constructed within at least a section of the basin perimeter to create a beach passage perimeter. The sloping area is constructed such that the inclination of the beach passage perimeter is between 5% and 30%. The sloping area may require the construction or placement of support slabs to provide structural stability in this location. For example, the support slabs may be made of reinforced concrete, shotcrete, plastic, or other supporting materials. For example, the sloping area may experience high foot traffic from users using the swimming lagoon.

[0039] The shape of the waterfront perimeter is preferably curved to create a more natural swimming lagoon appearance. Furthermore, the basin has a maximum width of 300 meters at its widest point. The width of the lagoon is defined as the measurement or extent of the lagoon from one side to the other; the smaller of the two dimensions of the lagoon measurement. The length of the lagoon is defined as the largest dimensional measurement of the lagoon.

[0040] The maximum width of the lagoon is limited to 300 meters. Because of the large distance, the visual impact of the entire lagoon is almost imperceptible at eye level.

[0041] The bottom of the basin is covered with an impermeable material to act as a water-retaining structure. Similar to a traditional swimming pool, the impermeable bottom material covering the basin includes a plastic liner, shotcrete, or a flexible material that does not require a thick concrete layer. The use of large, thick concrete surfaces is problematic because, in addition to being costly, it can create structural stress, leading to cracks, fissures, settlement, and potentially affecting the basin's structural properties.

[0042] In a preferred embodiment, among other solutions, the impermeable material comprises a plastic liner with a thickness of at least 1 mm. The plastic liner may come in various colors and shades, but is preferably white, blue, or light-colored to provide a strong turquoise hue to the water.

[0043] Therefore, the basin and its surrounding walls and / or sloping areas create a swimming lagoon within the previously excavated volume that formed the basin.

[0044] The embodiments described herein relate to swimming lagoons arranged and constructed to optimize the visitor experience. Specifically, the lagoon is arranged and constructed in such a way that the relationship between all elements and uses of the different areas of the lagoon enables guests and visitors to enjoy the experience and interact with different areas that can be designated for different purposes. Preferably, a sandy area is included within the swimming lagoon. However, there may be situations where a sloping sandy area with a swimming zone is impractical or undesirable for a particular site.

[0045] Furthermore, it is preferable to construct swimming lagoons in a manner that allows them to be used not only for swimming but also for several water sports, such as kayaking, stand-up paddleboarding, rowing, and waterskiing.

[0046] Although the swimming lagoon is man-made, it preferably includes a shape that easily mimics natural geometry, and includes a slightly elongated shape to provide visitors with at least one advantageous vantage point to experience the striking landscape of the lagoon and its surroundings. Preferably, the swimming lagoon is surrounded by vegetation such as plants and trees.

[0047] Furthermore, the swimming lagoon includes various elements and areas for providing an optimized visitor experience, preferably including at least one controlled-use area. This is achieved by constructing one or more barriers around the basin perimeter of the swimming lagoon to isolate areas of the lagoon, thus establishing a restricted-use area within which the swimming lagoon is located. In this case, the controlled-use area includes at least one beach access perimeter within the basin perimeter, thereby providing new recreational facilities and spaces for visitors. The barriers include at least one entrance point to selectively allow users access to the controlled-use area. The remaining area around the basin perimeter may optionally be an open-use area freely available to users, meaning it is an area without entrance fees. However, the controlled-use area preferably requires payment for tickets, vouchers, or other entry fees for use of such an area, which may be included in other fees or payments, such as entry may be included in seasonal tickets, or by becoming a member of an association or group, as part of an accommodation facility, etc.

[0048] Controlled-use areas can also be created around the swimming lagoon for other purposes. However, where a ticket-free area exists, separate entrance points must be included for both the controlled-use and ticket-free areas of the lagoon. This allows visitors to explicitly engage with one or both areas depending on their purpose for visiting the site and the lagoon, including natural sounds along the edges and artificial focal points to encourage walking and cultivate a sense of discovery. The swimming lagoon can be illuminated with a lighting system to allow for nighttime use. The lighting system includes external lighting systems and / or underwater systems.

[0049] As previously stated, preferably, the lagoon includes at least one controlled-use area for at least one beach area, wherein the beach area comprises a sandy beach and a sloping transition leading to the swimming lagoon. The controlled-use area can be designed such that the ratio of the total beach area to the lagoon area is at least 1:2. Furthermore, the placement and design of the beach area preferably takes into account the approximate orientation of the summer sun, thereby optimizing the visitor experience. In another embodiment of the invention, the controlled-use area surrounds the entire lagoon surface and may include additional amenities within the controlled-use area, such as leisure facilities including cafes, bars, restaurants, etc.

[0050] In an embodiment of the invention, the facilities surrounding the tropical-style lagoon are artificially arranged with a beach theme, including the use of blue and white inspired by beaches, beach pavilions, and lighthouses.

[0051] The swimming lagoon can also be surrounded by vegetation, such as plants and trees.

[0052] The invention also includes the construction of at least one additional recreational facility, comprising dining and commercial facilities capable of providing a relaxing environment surrounding a tropical-style lagoon. Examples of recreational facilities include restaurants, bars, kiosks, shops, cafes, eateries, beach centers, promenades, hotels, recreational facilities, virtual and immersive experiences, and similar facilities and amenities.

[0053] Ideally, an amphitheater should be built in the surrounding environment of the lagoon and near the beach area(s). This creates opportunities for hosting events, especially concerts and festivals. Other activities include beach music, beach dining, and other beach events, especially weddings and sporting events. The surrounding environment of the beach can include cafes, bars, restaurants, beach centres, and similar facilities and amenities.

[0054] Where there are ticket-free areas within the site, at least one ticket-free area comprises an optimized waterfront perimeter surrounding the swimming lagoon, which offers unobstructed views of the lagoon and is not directly in front of any beach area or flat open space that might affect the aesthetics of the landscape. Ticket-free areas include cafes, bars, restaurants, beach centres, promenades, hotels, entertainment facilities, virtual and immersive experiences, and similar facilities and amenities.

[0055] Screens can also be provided near the swimming lagoon for broadcasting content, family activities, and performances, and these screens can be located in the same sector as the amphitheater to create new event venues with the swimming lagoon as a backdrop. The screens can also be used for live streaming or recording events or general media, while the stage area can be used for broadcasting or hosting esports competitions, concerts, plays, performances, shows, etc.

[0056] Other components and methods embodying the principles of the invention can be configured within the spirit and intent of the invention. The arrangements described herein are provided merely as one example of an embodiment incorporating and practicing the principles of the invention. Other modifications and variations are within the knowledge of those skilled in the art and are included within the broad scope of the appended claims.
