APPENDIX ` F' Student Generation Multipliers A critical component of the school concurrency process is projecting the number of students that will be generated from with new residential development, a student generation multiplier was created. Because the number of students living in a housing unit varies depending on the type of residential housing, the student generation rate per residential unit is based on three housing types: single family, multi-family, and mobile home . Two key pieces of data were used to calculate student generation rates, including: the Geographic Information System (GIS) parcel file from the Indian River County Property Appraisers office with associated land use and attribute data (2005), and the GIS Point file based on the October 2005 FTE Survey data provided from the School District (for the school year 2005 -2006). A spatial join was applied to these key files resulting in one database based on a common location . Once the data was joined, the student GIS Point file was assigned a housing type based on the closest proximity of a residential parcel to the GIS centerline point. As a 100 percent student inventory (not a sample set), the volume of data used ( 16 , 857 geo-coded students) was large enough to offset occasional land use assignment errors. The student database was then sorted by grade and housing type. The student generation rate (multiplier) was then calculated by dividing the total number of students (by school type) by the total number of occupied dwelling units by residential type. The occupied dwelling unit counts are based on an average 10 percent occupancy rate applied to the existing unit count by type and reconciled to the permanent household count for year 2005 . The student generation multipliers by residential housing type from the "Indian River County Student Generation Rates by Housing Type" report prepared by Fishkind and Associates, Inc . (May 24, 2006) are provided in Table 1 below.
