The range of proposals will, according to the agency, ensure the park's future as an 'iconic' location in the capital.
However the LDA, which now has control of the park's future, has not revealed whether or not there is a future for the famous Modernist 1960s National Sports Centre building.
A consultation period on the park's future will start next month with the following proposals under debate:
increase the amount of parkland, with high-quality greenspace through the centre of the park;
create attractive, vibrant entrances;
make the park a must-see destination for London once again; and
ensure the park contributes to the regeneration of surrounding areas
LDA executive director for regeneration Tony Winterbottom said: 'After 18 months of analysis of Crystal Palace Park's needs and extensive consultation with local people, we are ready to put forward our proposals for the park's future.
'These could have a dramatic impact on the park and help to boost the surrounding area, so we want as many people as possible to have their say on the proposals.
'That's why we'll be holding the consultation event in two places in the park from 20 October and will follow this up with a roadshow in the local area over November,' he added.
