Stakeholder Issues and Concerns(Pump Stations)

• Capacity and operation of pump stations
  consistent with PIR
• Hardy Pit is not a storage reservoir on Project
• Redundant pump capacity included
• Pump Station operation will mimic existing
  structures

24
Stakeholder Issues and Concerns(other Project
Features)

• Location and sizing of protection levees is being
  addressed in a separate BODR.
• Project will not change water quality
• Working with DOF recreational opportunities
  will be consistent with DOF Land Management Plan
• Additional modeling is being done to determine if
  there are impacts to Tamiami Trail
• Pump stations shall be operated in accordance
  with the Permit criteria and Operation Plan
• All modeling will be completed before Final
  Design
• Uplands and Wetlands were used as criteria in
  determining Project benefits
