Calculation of Preliminary Growth Allocation Oregon SDC statutes [ORS 223.229] define the portion of system costs that may be allocated to growth through the SDC. For an improvement fee SDC, the growth allocation is determined by the projected costs of capital improvements that are needed to increase capacity in the systemto meet the demands of new development. Demands for capacity in the system – both for existing and future park users (growth) – are generally based on the projected level of service (LOS) which quantifies total future park acreage or facilities per demand unit (generally population). Future parks acreage is determined by the existing system inventory plus those system elements added by projects in the Project Plan. The capacity requirements for existing development and growth are estimated by multiplying the future LOS for each park type by the population of each group. Project Plan costs are then allocated in proportion to each group’s relative need for the new acreage, as determined by the capacity analysis. Table 1 at the end of this document presents a capacity analysis based on the proposed Project Plan. In Table 1, columns ‘a’ and ‘b’ provide existing and planned future LOS calculations by park type for developed and undeveloped land. The future LOS reflects total planned acreage, adjusted for park projects included in the Plan that are not owned or funded by the City. The future LOS is based on 1 forecast population for 2025, and for all parks projects projected for completion by 2025. Total capacity needs for the existing 2004 population and the increment of growth between 2004 and 2025 are presented in columns (f) and (h) of Table 1, respectively. Capacity needs are the product of the future LOS and the population attributable to each population group. As an example, for neighborhood park development (in the bottom half of the table), the additional need for neighborhood park development for the existing population (36.5 acres, shown in column ‘g’), is equal to the total need (132.3 acres shown in column ‘f’) less the existing inventory (95.8 acres shown in column ‘c’), as existing park users’ needs are assumed to be met first by existing parks and facilities. For growth, the additional need of 34.7 acres (column ‘j’) from projects equals the total need (column ‘g’). The capacity analysis for land acquisition and development of other park types follows this same methodology. Table 2, also included at the end of this document, shows the allocation of project list acreage to existing development and growth, based on the capacity analysis provided in Table 1. Project list acreage in Table 2 comes from column ‘d’ in Table 1. Existing deficiency and growth acreages also come from Table 1, columns ‘g’ and ‘j’, respectively. Using the example stated above for neighborhood park development, the growth need is calculated to be 34.7 acres, which represents 49 percent of the total acreage (71.2 acres) added by the project list. This percentage is then used in Project Plan as the preliminary growth allocation for all neighborhood park development projects. A separate capacity analysis was conducted for certain facility types for which separate project costs are itemized in the project list. Similar to the park acreage analysis, the capacity analysis for facilities is based on the future LOS for the existing and 2025 populations, but the capacity is expressed as number of facilities per population rather than by acres. 1 2025 is used as the capacity planning period for all part types, except natural area parks, where acquisitions and development within the planning window are assumed to meet capacity needs through 2050.
