A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

The solution is directed to a bleacher step access prevention system. The system is configured to be locked in place over a stairway of a retracted bleacher system in order to prevent climbing of the stairway when the bleacher system is in a retracted state. Certain embodiments are configured to accommodate handrails of the bleacher system so that handrails do not have to be removed from the stairwell when the bleacher system is in a retracted state.

A telecommunication and multimedia management apparatus and method that supports voice and other media communications and that enables users to: (i) participate in multiple conversation modes, including live phone calls, conference calls, instant voice messaging or tactical communications; (ii) review the messages of conversations in either a live mode or a time-shifted mode and to seamlessly transition back and forth between the two modes; (iii) participate in multiple conversations either concurrently or simultaneously; (iv) archive the messages of conversations for later review or processing; and (v) persistently store media either created or received on the communication devices of users. The latter feature enables users to generate or review media when either disconnected from the network or network conditions are poor and to optimize the delivery of media over the network based on network conditions and the intention of the users participating in conversations.

An urban transformation and construction method is disclosed that creates a tropical style swimming lagoon at vacant and/or abandoned sites. The transformation includes demolishing at least part of the vacant or abandoned site, excavating material from within the site; forming a basin for a large water body having a surface area of at least 3,000 m2, and constructing water containment walls on a first section of the basin to form a waterfront perimeter. The shape of the waterfront perimeter is mainly curved, the basin has a maximum width of 300 meters, and the bottom is covered with a non-permeable material. A sloped access area is constructed in a second section of the basin to form a beach. A barrier is constructed to control access into the area including the beach. At least one recreational facility is constructed including restaurants, bars, kiosks, stores, and/or cafes about the waterfront perimeter.
