Improvements to be Constructed at the Sole Expense of the Developer. In cases where the need for an off-tract improvement is created by the proposed subdivision or site plan, and where no other property owners receive a special benefit thereby, the Planning Board may recommend to the Township Council that it require the subdivider or developer, as a condition for subdivision or site plan approval, at the subdivider's or developer's expense, to acquire lands outside of the subdivision or tract and improve and dedicate such lands to the Township or the County, or, in lieu thereof, require the subdivider or developer to deposit with the Township a sum of money sufficient to allow the Township to acquire and to improve such lands.
