The IOC board seat representing the Association of National Olympic Committees (ANOC) will be elected at a four-day annual meeting starting Wednesday in Lima.
The IOC gathering, which includes a full session of the sports body's members from September 13-17, is taking place against a backdrop of corruption intrigue.
The report focuses exclusively on changes to the Los Angeles proposal since the release of the IOC Evaluation Commission 2024 report on 5 July, as well as on the consequences of awarding the Olympic Games 2028 11 years out.
"The report confirms that Los Angeles is ready to host the Olympic Games 2028", Baumann said. LA 2028 will still require no new permanent venues to stage the Games.
The report follows the IOC Evaluation Commission's comprehensive inspection visit to Los Angeles in May.
"The Evaluation Commission is confident that Los Angeles and Paris would mutually benefit from the opportunities for collaboration and shared knowledge that would result from a simultaneous award".
The IOC's executive board meanwhile will hear updates on Tokyo's plans for the 2020 Olympics as well as Beijing's preparations for the 2022 Winter Games.
LA 2028 CEO Gene Sykes said "LA 2028 is grateful to Evaluation Commission Chairman Patrick Baumann and his colleagues for their confidence in our readiness to host the Games and for their expert guidance throughout this two-year process".
It confirmed the University of California, Los Angeles would remain the Olympic Village and their concept had "strong support from all levels of Government".
The vacant seat on the board will be filled by an election during this week's International Olympic Committee gathering in the Peruvian capital Lima.
