Nearly £3million could be invested in Bridge of Don amenities if plans to build 550 homes are approved.
Proposals for the housing at Cloverhill in the Aberdeen suburb have been submitted to the city council.
Planners have now calculated how much developer Cognito Oak should be made to pay to cover the cost of more people living in the busy area.
Overall, the developer would be obliged to pay at least £1.31m although that sum could increase to £2.98m, dependent on the facilities included in the plans.
The bill could increase again, if the local authority’s transport planners identify any further cause for investment.
Nearly 140 of the homes built are required to be marketed as affordable housing to meet council rules.
More than £680,000 would be required to fund an extension to Scotstown School, as the development is forecast to leave it over capacity.
Education planners believe the primary school would have around 75 pupils too many in its catchment area if the plans are approved.
But the developers would not be expected to put anything towards Bridge Of Don Academy, which has enough space to accommodate any new pupils on the school roll.
David Berry, the council’s head of developer obligations, wrote in a report for councillors: “The site is within the catchment area for Scotstown School.
“Factoring this development into the 2018 school roll forecasts will result in the school going over capacity.
“A contribution is therefore required towards the provision of additional capacity through extension of the school building.”
If given the go-ahead, Cognito Oaks would be asked to pay another £563,000 to fund the expansion of Scotstown Medical Practice and other health facilities serving those who would live at Cloverhill.
The developers would also be expected to build a key path in the council’s plans for that part of the city and pay more than £60,000 for work to connect paths and streets to the existing surrounding network.
A community meeting space and a full-sized football pitch, associated facilities and parking included in the proposals would be enough to save the builders another £1.67m for required community and public sports facilities.
Councillors will soon consider the plans.
But currently the local authority has postponed meetings on all matters, bar urgent business, until after the coronavirus lockdown.
