Critics of the Lynnsport and Marsh Lane development say their concerns have still not been addressed.
But planning officials say the latest phase should be approved, subject to the completion of legal agreements.
Members of West Norfolk Council’s planning committee will debate proposals for a site known as Lynnsport 3 when they meet on Monday.
And, in their report to members, officials suggested that potential changes to planning policies potentially gave the application greater significance.
They said: “There is a need for housing in the borough (both market and affordable), and this application, which is for development of part of a wider housing allocation, is an important contributor to the authority’s housing supply.
“The development would provide 54 dwellings on a site that is extremely well located within the town.
“Further, the development would improve the connectivity of existing adjacent residential developments in a sustainable fashion.”
The scheme, which is being developed by the borough council in partnership with Lovell, has been the subject of an ongoing campaign by local residents, who argue that it is already ruining a precious area of green space that is well used by the existing communities.
Those concerns have been echoed by members of the Lynn Civic Society, who have repeated their demands for a green infrastructure strategy for the town.
The group said: “No significant alternative green space proposals are being made for Kings Lynn.
“There will already be an increase in population in the locality and proposed population increases in the district will place more pressure on Lynnsport as a facility.
“It seems crassly short-sighted to constrain future sports and recreation development at the site by building on the outlying spaces.”
The society also claimed that the authority’s plans for additional tennis courts and hockey pitches “misunderstand the nature of what is being lost.”
But officers said: “The development of the wider allocation will result in overprovision of open space, as required by policy in the locality of the site, which will benefit not only the development, but the wider neighbourhood.”
