Comprehensive Plan Capital Improvements Element Applicable elements of the plan identify the rates to be applied to each project to determine facility demand. Traffic volumes, for example, can be derived by applying a trip rate to the size of the project. Sanitary sewer and potable water both have rates of 250 gallons per day per equivalent residential unit. Other public facility rates are discussed fully in their applicable Comprehensive Plan Element. Like existing demand, committed demand must be determined on a facility by facility basis. For example, both existing demand and committed demand must be determined for each major roadway, each school, each treatment plant, each major drainage conveyance, and the active cell in the landfill. Also, like existing demand, committed demand estimates must be modified as projects are completed; committed demand estimates must also be modified as new development orders are approved and old development orders are terminated. Proiected Demand The third type of demand is projected demand. This consists of two types. One is non- committed/non-reserved, single-family lot demand for all subdivisions, while the other is new project demand. Non-committed/non-reserved single-family lot projected demand to the facility impacts associated with construction on individual single-family lots in platted subdivisions and construction on legally established individual single-family unplatted lots and acreage will constitute a de minimus impact on public facilities and thus be exempt from concurrency review. Single-family home traffic impacts will be accounted for through tracking single-family trips for use in development project traffic studies and annual traffic count updates. The second type of projected demand is new project demand. For each new project, demand estimates must be made on a facility by facility basis. Only if sufficient available capacity exists for each facility to be impacted can the project be approved and a development order issued. Upon issuance of a development order, the estimated impacts on each facility would be considered as committed demand. Availability of Capacity Facility capacity can be assessed two different ways. First, facility capacity can be determined by facilities that are existing and available; examples would be existing treatment plants and existing roadways with a set number of lanes. The second manner for assessing facility capacity is to consider both existing, in -the -ground facilities as well as facility expansions or new facilities which are programmed but not yet existing. As part of the concurrency review process, the capacity of existing, in -the -ground facilities will be considered in all cases. Programmed facilities will be considered in assessing capacity for each public facility category when the following conditions are met: ➢ For sanitary sewer, potable water, solid waste and drainage facilities: Community Development Department Indian River County Adopted December 3, 2019, Ordinance 2019-020 42
