- Water With the proposed land use designation, the subject property could accommodate 147 residential units, resulting in water consumption at a rate of 147 Equivalent Residential Units (ERU), or 36,750 gallons/day. This is based upon a level of service of 250 gallons/ERU/day. The subject property is presently served by.the South County Reverse Osmosis Plant which currently has a remaining capacity of approximately 2,100,000 gallons/day and can accommodate the additional demand generated by the proposed amendment. When the North County Reverse Osmosis Plant is complete, it will serve the subject, property. This plant, which is currently being designed, will have a capacity of approximately 2,000,000 gallons/day and will be able to accommodate the additional demand generated by the proposed amendment. - Wastewater Based upon the most intense use allowed under the proposed amendment, development of the property will have a wastewater generation rate of approximately 147 Equivalent Residential Units (ERU), or 36,750 gallons/day. This is based upon the level of service standard of 250 gallons/ERU/day. County wastewater lines extend to the site from the West Regional Wastewater Treatment Plant, which currently has a remaining capacity of more than 800,000 gallons/day and can accommodate the additional wastewater generated by the proposed amendment. - Solid Waste Solid waste service includes pick-up by private operators and disposal at the county landfill. The county's adopted level of service standard for landfill capacity is 2.37 cubic yards/person/ year. With the county's average of approximately 2.3 persons/unit, a 147 unit residential development would be anticipated to house approximately 338 people (2.3 X 147). For the subject request to meet the county's adopted level of service standard of 2.37 cubic yards/person/year, the landfill must have enough capacity to accommodate approximately 801 (338 X 2.37) cubic yards/year. A review of the solid waste capacity for the active segment of the county landfill indicates the availability of more than 895,000 cubic yards. The active segment of the landfill has a 2 year capacity, and the landfill has expansion capacity beyond 2010. Based on the analysis, staff determined that the county landfill can accommodate the additional solid waste generated by the site under the proposed zoning district. - Drainage All developments are reviewed for compliance with county stormwater regulations which require on-site retention, preservation of floodplain storage and minimum finished floor elevations. In addition, development proposals must meet the discharge requirements of the county Stormwater Management Ordinance. Since the site is located within the M-1 Drainage Basin and the Indian River Farms Water Control District (IRFWCD), development on the property will be prohibited from discharging any runoff in excess of two inches in a twenty-four hour period, which is the approved IRFWCD discharge rate. In this case, the minimum floor elevation level of service standards do not apply, since the property does not lie within a floodplain. However, both the on-site retention and discharge standards apply. With the most intense use of this site under the proposed amendment, the maximum area of impervious surface would be approximately 240,451 square feet, or 5.52 acres. The maximum runoff volume, based on that amount of impervious surface and the 25 year/24 hour design storm, and given the IRFWCD two inch discharge requirement, would be approximately 569,736 cubic feet.
