Bristol's Parks & Green Space Strategy was expected to get the go-ahead last week but a photocopying error meant consultation documents for public viewing were sent without maps and plans.
"It was felt this was not to the standards we would expect of ourselves," a representative said. "It was a technical error and the matter will come before the cabinet on 21 February."
The initiative, to be paid for in part by selling off more than 14ha of existing parks to developers, aims to improve green areas and play zones, wildlife and sports areas (HW, 10 January).
A strategy-delivery team is due to be formed later this year and will look at which parks in the city are "surplus to requirements".
Councillors insist the strategy is "hugely important" for the city.
Executive member for health, culture and leisure Rosalie Walker insisted last week: "I share the desire to see further improvements and better maintenance. I will urge cabinet colleagues to take a critical look at the strategy and see the potential investment benefits for the city and local communities."
