If the Planning Board and/or Town Board finds that due to size, topography or location of the Mobile Home Overlay (MHO) District, land for parks, open spaces, playgrounds or other recreational purposes cannot be properly located therein, or that the same are not desirable, the appropriate Board shall require, prior to approval and filing of the proposed plan, that a payment to the Town of Schodack Recreational Trust Fund be made in an amount defined by the Town Board's fee schedule per mobile home lot within the Mobile Home Overlay (MHO) District being considered for approval. Such amount shall be paid to the Town of Schodack at the time that final approval of the plan is made, and no such plan shall be finally approved nor filed until such payment has been made.
