Residential In 2007, there were 51,502 residential units in the unincorporated county. At that time, 19,693 acres of residential land had been developed. Consequently, there was an average of .38 acres per unit in 2007. According to projections, the unincorporated county will need 67,690 residential units in 2030, an increase of 16,188 units. Assuming that the mix of housing types in the county remains constant and using the .38 acres per unit proportion for the 2030 projection of 67,690 units needed, there would be a need for 25,883 acres of developed residential land at that time. In the unincorporated county, 32,761 acres are currently designated for residential use. Because more land is already designated for residential use than will be needed in 2030, sufficient land is available to accommodate the county's projected 2030 population. Therefore, no additional residential land and no density increases are needed at this time. Because of recent annexations, the county's municipalities, particularly the City of Fellsmere, now contain a significant amount of undeveloped residential land. As this land is developed in the future, the share of the county's population located within the municipalities will likely increase. As the municipalities' share of the county's population increases, the unincorporated county's share will decrease, thereby reducing the unincorporated county's projection of housing need. Currently, 66% of all residential units in the county are located in the unincorporated county area, while the remaining 34% are located within the county's five municipalities. Upon build- out, the unincorporated county's share of residential units will decrease to approximately 56%. This is largely due to the anticipated growth of Fellsmere, which annexed 39 square miles of land between 1998 and 2007. At this time, Fellsmere contains approximately 2% of all residential units in the county. Upon build -out, it is anticipated that Fellsmere will contain 26% of all residential units in the county, while the remaining four municipalities combined will contain only 18% of all residential units. Residential Allocation Ratio A Residential Allocation Ratio (RAR) compares the number of residential units permitted by a jurisdiction's future land use map to the number of residential units that are needed to accommodate the jurisdiction's projected population within its planning time horizon. Along with historic land use patterns and other factors, an RAR can be a useful tool to determine a jurisdiction's residential land use needs. The time period used to calculate Indian River County's current RAR is from 2007 to 2030. The following formula is used to calculate the RAR: Total number of units allowed by FLU Map — Existingu2007) Projected number of units needed in 2030 — Existing units (2007) Future Land Use Element 73
