In lieu of individual systems, applicants may design and build regional facilities in accordance with the design requirements of Category A or B set forth in Volume III of the Manual, as applicable and with excess capacity which, when completed, may be dedicated to the County. Such a facility may be on-site or off-site. Upon County approval of the facility, the County may:
A. Accept the dedicated facility; and
B. If funds are available as determined by the Director of Pierce County Planning and Public Works and the facility is constructed in a location within a basin studied by Pierce County Surface Water Management and is currently budgeted for in the approved six-year capital facilities plan, reimburse the developer for the excess capacity provided by the facility at a rate mutually agreed upon; or
C. Enter into a latecomers agreement with the developer for reimbursement as other properties are developed which opt to discharge to the regional facility.
