The first phase of the planned new park will open to the public in January 2019.
Ultimately, the new amenity will be five times larger than Fitzgerald’s Park.
The Marina Park will surround the redeveloped Páirc Uí Chaoimh stadium and all-weather pitch stretching from Monahan Road and Centre Park Road towards Blackrock village.
The first phase of the new park will cost €7 million and cover the area west of the stadium between Monahan Road and the Atlantic Pond.
Demolition work began in June and the site has now been substantially cleared.
The phase one park plans are due to go to tender with construction set to begin in early 2018 with an expected opening date of January 2019.
Liam Casey, Cork’s Parks Superintendent said Marina Park is identified as one of the essential developments in the South Docks to act as a catalyst for the future development and will include spaces for outdoor events and performances.
“It will provide a major green infrastructure bookend on the east of the city centre to complement the fully redeveloped Fitzgerald’s Park west of the city centre,” he said.
“It will provide a link from the Blackrock/Passage walk/cycleway through the city centre, along Mardyke Walk on to the Lee Fields, with an objective to create an off-road connection to the Regional Park, Ballincollig.”
Mr Casey said Marina Park will influence the detail designs for Tramore Valley Park, Bishopstown Park and playground and the North West Regional Park, all three of which are at various stages of development.
