Measure: Policies: The City shall require the use of central sewer systems in new development unless interim facilities are approved, regulate lot sizes in areas where septic tanks are approved, and prohibit the use of package treatment systems in environmentally sensitive areas Requirement of Central Sewer Collection on the Econlockhatchee River Area The City shall require that all development within two thousand (2,000) feet of the Econlockhatchee River utilize a central sewer collection and treatment system Monitoring of Industrial Uses The City shall continue to monitor, business tax receipt, zoning, and subdivision requests to regulate the use of individual wastewater treatment systems for industrial uses Minimum Lot Sizes for the Use of Septic Tanks The City shall specify minimum lot sizes consistent with Chapter 10D-6 of the Florida Administrative Code for the use of septic tanks in residential areas of the City where centralized sewer service is not yet available, and the soils do not have severe limitations for septic tank use Minimum Lot Sizes for the Use of Septic Tanks in Areas with Soils with Severe Limitations The City shall require a minimum lot size of one acre for new residential development in areas where soils have severe limitations for septic tank usage 4-7

6 WASTEWATER and centralized sewer is not yet available. The following soil types shall be considered to have severe limitations for septic tank usage: 1. Adamsville - Sparr Fine Sands 2. Arents 3. Basinger and Delray Fine Sands 4. Basinger, Samsula & Hontoon Fine Sands 5. Basinger & Smyrna Fine Sands 6. Canova and Terra Ceia Mucks 7. Eaugalie & Immokalee Fine Sands 8. Immokalee Sand 9. Brighton, Samsula & Sanibel Muck 10. Malabar Fine Sand 11. Myakka & Eaugalie Fine Sands 12. Pineda Fine Sand 13. Pomello Fine Sand 14. Pompano Fine Sand 15. St. Johns and Eaugalie Fine Sands Central Sewer Connection Requirements Criteria All new residential development in areas with severe soil limitations for septic tanks, and all non-residential development shall be required to provide or to connect to a central sewer service system. Temporary sanitary sewer service consistent with the other objectives and policies of this element may be allowed until a central sewer service becomes available Location Restrictions for Wastewater Treatment Systems Individual and package wastewater treatment systems shall be prohibited in wetlands, floodplains, and buffer areas surrounding surface water bodies Septic Tanks in Conservation Land Use Septic tanks shall be allowed in Conservation land use areas only when necessary for facilities required to oversee said conservation area OBJECTIVE: Provision of Adequate Wastewater Services To correct deficiencies, maximize the use of existing facilities, and minimize the City's cost in providing adequate service for wastewater treatment and collection. Measure: Policies: The City shall prioritize the extension of central sewer service, regulate the design of package treatment and collection systems, pursue grants for extending service to low and moderate income areas, require new development to fund required system expansions, and maintain City-owned facilities at adopted level of service standards Acquisition of Privately Owned Wastewater Service Plant The City shall evaluate, and if financially feasible, pursue the acquisition of privately owned wastewater service providers within the City s corporate limits, 4-8

7 WASTEWATER would such acquisition provide increased service to residents within the specific service area Requirement of Sewer Lines in New Developments All new development, in areas designated for sewer expansion and recognized as the City service area, shall install and dedicate to the City sewer lines in accordance with the approved Master Plan and other certificated sewer areas if City Council approves a temporary treatment option Dedication of Sewer Treatment Facilities All new residential wastewater collection, pumping and transmission, treatment, and disposal facilities shall be dedicated to the City unless an interlocal agreement or development agreement otherwise establishes a maintenance authority Funding Responsibilities for Sewer Capacity Expansion New development shall fund the cost of required capacity expansions, and/or extension of central sewer lines Funding Assistance for Sewer Service Expansion The City shall pursue Community Development Block Grant (CDBG) funds and other available sources to extend central sewer service to low and moderate income areas Sewer System Conversion Requirements The City shall require the reasonable conversion of existing land uses from septic tanks and package plants to central systems as the system is expanded Criteria for the Expansion of Sanitary Sewer Services The City shall not expand the central sewer service area without first evaluating the impact on service delivery within the established service area. No expansion shall be permitted if the adopted level of service cannot be maintained and the percent of existing capacity currently being used is less than twenty-five percent (25%). The City shall extend central sanitary sewer service in the following order of priority: A. Service to existing areas that present an immediate threat to public health or safety or produce serious pollution problems. B. Maintenance or expansion of existing wastewater systems to correct deficiencies and/or meet adopted level of service standards. C. Economic Development Target Areas identified in the Strategic Economic Development Plan, and Development Corridors identified in Policy D. Service to new development areas outside the initial service area. 4-9

8 WASTEWATER Assistance for Central Sewer Connection The City shall coordinate with Seminole County and the Florida Department of Environmental Protection to assist property owners in connecting to the central sewer system when either agency identifies deficiencies in areas serviced by septic tanks Monitoring of Central Sewer Facilities The City shall monitor all City-owned facilities ensuring efficient wastewater conveyance and leak detection Notification of Health Code Violations The City shall continue to notify the Seminole County Health Department of any health code violations regarding the use of septic tanks OBJECTIVE: Maintenance of Sewer Facilities To provide and maintain facilities with sufficient capacity to treat and dispose of the present and projected wastewater volumes. Measure: Policies: The City shall regulate land use intensities to reflect sewer availability; program system improvements to maintain level of service standards; require new development to comply with adopted level of service standards and certify sewer availability; and encourage the use of reuse water and other alternative water sources for irrigation Level of Service Standards The City shall require new development to comply with the following level of service standards: A. Three hundred (300) gallons/day/equivalent Residential Connection (ERC). B. Peak facility capacity shall be maintained at a minimum of two times the permitted capacity. C. Adherence to all rules and requirements of Florida Department of Environmental Protection (FDEP) Water and Wastewater Master Plan System improvements and expansions shall be constructed in accordance with the Water and Wastewater Master Plan Land Uses and Availability of Central Sewer Services Land use intensities on the 2025 Future Land Use Map shall reflect the availability of central sewer service. Only low density residential uses shall be permitted in areas without central wastewater service or an environmentally acceptable temporary alternative Availability of Sewer Services Capacity The City shall annually evaluate available capacity to ensure that development 4-10

9 WASTEWATER consistent with the 2025 Future Land Use Map can maintain the adopted level of service. Any potential deficiencies will be corrected by revising the 2025 Future Land Use Map or the Capital Improvements Plan (CIP) or by purchasing additional capacity from Seminole County Certification of Sewer Services Availability Development permits shall not be issued and rezoning shall not be approved without certification that adequate sewer service is available. In service areas with pre-purchase capacity requirements, only proof of purchase shall constitute certification Average Daily Flow (ADF) Capacity The City shall ensure that sufficient capacity is maintained by following the requirements of Chapter , Section , FAC, and by maintaining a Capacity Analysis Report annually Reclaimed Water Provision of water reuse, reclamation of effluent discharge and/or other alternative sources for irrigation, industrial, and other non-potable water use applications shall be in accordance with the adopted Reclaimed Water Master Plan and subsequent Engineering Studies Multi-Jurisdictional Approach The City shall collaborate with Seminole County to pursue a multi-jurisdictional approach to the use of reuse waters as provided for in the City of Oviedo/Seminole County Interlocal Agreements Industrial Pre-treatment Regulations The City shall enforce its industrial pretreatment ordinance as required by the EPA, Title 40, CFR, Part Feasibility of City Sewer Treatment Facilities The City should pursue feasibility studies to purchase, or construct its own sewer treatment facilities to meet the City's needs OBJECTIVE: Use of Existing Sewer Facilities To maximize the use of existing facilities, promote economic development, and discourage urban sprawl. Measure: The City shall first serve interior areas of the City, the Economic Development Target Areas identified in the Strategic Economic Development Plan, and Development Corridors identified in Policy ; evaluate service area expansion impacts on service delivery and adopted levels of service; require new development to fund requested service area expansions, and not extend central sanitary sewer services outside the municipal boundaries. 4-11
