SYSTEM DEVELOPMENT CHARGE METHODOLOGY The allocation fractions from Table 3 are used to distribute costs by facility component to capacity parameter, as was done for the existing system cost allocations. The basis for these allocations is described in Appendix B. Step I-3 of the project cost allocation methodology is to allocate costs to project types. The three project types, which are intended to be representative of the complete project list, are: 1. Capacity-Projects or portions of projects that are related to increasing liquids and/or biosolids conveyance, treatment, and disposition capacity beyond existing design standards (i.e., projects that provide the next capacity increment within the planning period). 2. Performance Improvements- Projects that increase system capacity by increasing the level of performance provided by facilities. Unlike 'capacity' projects that relate only to the next increment of capacity, performance upgrades are generally sized based on total projected capacity needs at the end of the planning period (existing and future). 3. Rehabilitation-Projects designed to remedy an existing system deficiency and do not enhance system capacity. Capacity and performance upgrade projects can be new facilities, or upgrade/expansion of existing facilities. Rehabilitation projects are the replacement of outdated or worn out equipment or facilities. The majority of the projects will typically fall completely into one project type. However, some projects may be split between capacity and performance types. The general criteria for allocating projects to the above categories are shown in Table 5. These criteria should be applied in the development of specific projects for inclusion in the appropriate planning . document or project list and should be considered and evaluated as part of the process of adoption of such a plan or project list.
