The plans include building ponds, reed beds, a meadow and wetlands in the Rothley Brook Valley section of the park, a flood relief basin.
The 100ha park was established in the early 1980s and includes grassland, plantation and broadleaved woodland. But the land dates back much further to a royal hunting ground.
The southern section is higher ground with good views; the northern part including the valley is made up of flat meadow land.
Leicester City Council said its parks and nature conservation officers want the views of locals before pushing ahead with the plan.
"The park is very much in its early stages of development," said the council. "Ancient tracks pass through the park and parts are susceptible to occasional water-logging."
