somewhat rapidly. Such soils types are not considered ideal if water storage in a reservoir system is the goal, and would likely indicate that seepage from the reservoir to the surficial ground water will occur unless hydraulic controls are put in place. The soils are appropriate to support a reservoir system and associated berm structure. Permitting Investigation Several local, state and federal permits will be required as part of this project. While some the details are not fully known due to insufficient information, more specific requirements are to be obtained during pre -applications with other regulatory agencies once a more detailed design is underway and site verification of certain environmental factors has been completed. The following permits are required: An FDEP Application for a Specific Permit to Construct Potable Water System Components for the construction of the pump stations, transmission piping, reservoir and surface WTP; 2. An FDEP Environmental Resource Permit (ERP) for the minimal storm water impacts associated with the perimeter roadway. Based on the ultimate location selected, the ERP may be required to address wetland mitigation as well. A joint application to FDEP with review by the Army Corps of Engineers would then be required. 3. A modification to the County's SJRWMD CUP No. 10524 to include surface water as a supplemental supply source; 4. An IRFWCD connection permit for the overflow structure into the Lateral J, as well as for use of Right -of -Way (if needed) during construction; possible temporary permit to discharge dewatering well water to the canal system 5. An Indian River County Application for Major Site Plan Approval. This assumes that the project site plan will include more than 5,000 square feet (sf) of new impervious area (entrance, maintenance/perimeter road, pump slabs, etc.). Projects with between 5,000 and 150,000 sf of new impervious area can be approved at the staff level with no involvement from the Planning and Zoning Commission; 6. An Indian River County building department construction permit for the reservoir, pump stations and electrical service; 7. Indian River County ROW permits for use of road ROWS for transmission piping and pump station crossings; 8. Indian River County Utility Construction Permit; and 9. Depending on the site layout and impacts, a permit for impacts to protected species may be required from USFWS or FWC. In addition to the permits listed above, the Department of Health (DOH) requires a minimum setback for potable water features of 200 feet from on-site sewage disposal systems (i.e. septic J:\Utilities\UTILITY - Engineering\WATER\Alternative Water Supply\Portofino Preserve aka Blackstone 83 acre site\Due Diligence Report for BCC 02_16_2016\Agenda - Due Diligence Report and OPC for 83 acre site for BCC meeting 02_16_2016 v2 cmc.docx Page 8 of 14 106
