As part of the application for site plan approval, Planning Board may impose such reasonable and appropriate traffic controls and/or monitoring of traffic conditions, including staggering of work hours, staggering of ingress and egress or some use of mass transport or van pooling, to the extent and for such reasonable time periods as such controls may be required by the anticipated traffic to be generated by the proposed development during peak hours. However, where it appears that such controls or agreement involves a capital contribution of public funds for any road, intersection or other off-site improvements, then, to the extent of such expenditure or public funds, the approval of the Borough Council shall also be obtained.
