The Transportation SDC fee is comprised of both a reimbursement fee and improvement fee. The value of extra capacity in existing transportation infrastructure is apportioned to projected growth, expressed in terms of daily vehicle trips, to determine the Transportation SDC Reimbursement Fee. In addition, the value of extra capacity in planned transportation infrastructure is apportioned to projected growth in the same manner, to determine the Transportation SDC Improvement Fee. The total Transportation SDC Fee is calculated using the sum of the two fees.
