Enabling/Regulating Authority

Florida Statute 125



Background Discussion
  • The federally authorized Lido Key Hurricane and Storm Damage Reduction (HSDR) Project includes beach nourishment on Lido Key using sediment from the two adjacent passes and the construction of two groins to stabilize the southern shoreline.  Big Sarasota Pass is designated as the primary and initial sand source under Florida Department of Environmental Protection (FDEP) Permit No. 0333315-001-JC.  A benthic resource investigation in 2014 documented 1.68 acres of seagrass (shoal grass [Halodule wrightii]) inside the Big Sarasota Pass borrow area boundaries, and based on coordination with FDEP, up front mitigation is required to offset impacts to this seagrass.
  • The City of Sarasota and the U.S. Army Corps of Engineers (USACE) have been coordinating closely with FDEP throughout the permitting process to identify an appropriate seagrass mitigation site.  This coordination has also included communication with Florida Fish and Wildlife Conservation Commission (FWC), U.S. Fish and Wildlife Service (USFWS), and National Marine Fisheries Service (NMFS) in order to obtain agency guidance and feedback on potential mitigation sites.
  • Based on this coordination and additional coordination with Manatee County staff, the City of Sarasota and the USACE have proposed constructing their mitigation within the Perico Preserve Seagrass Basin in Manatee County.  This site is located in the same watershed as Big Sarasota Pass; therefore, FDEP confirmed that it may be a viable mitigation site for the Lido Key HSDR Project.  While other potential mitigation sites were considered and evaluated, the Perico Preserve Seagrass Basin mitigation option is the most ecologically beneficial and cost effective option.
  • Manatee County Parks and Natural Resources Department (MCPND) and their consultant (ICON Consultant Group, Inc.) are working with the City of Sarasota and USACE and their consultant (CB&I) on developing a seagrass mitigation plan that will utilize a portion of Manatee County’s Rookery at Perico Seagrass Advance Mitigation site as compensatory seagrass mitigation to offset seagrass impacts proposed by the Lido Key Hurricane and Storm Damage Reduction (HSDR) Project. The specific acreage within the Rookery at Perico to be utilized for the Lido Key HDSR project has not been formally determined and is pending assessment by FDEP.  The amount required is estimated between 2.9 and 3.2 acres.  There is 12.25 acres of habitat available within the basin for seagrass mitigation.
  • Manatee County permitted and constructed the Rookery at Perico Seagrass Advance Mitigation project with the intent to provide compensatory mitigation to public agencies that require compensatory seagrass mitigation to offset permitted seagrass impacts. Manatee County intends to provide compensatory mitigation credit through the sale of the right to implement seagrass establishment within a to-be-determined portion of the constructed tidal basin at the Rookery at Perico Seagrass Advance Mitigation project. Manatee County does not intend to convey any real property interests as part of the sale transaction. MCPNRD staff has determined that the proposed use of the Rookery at Perico Seagrass Advance Mitigation site by the City of Sarasota and USACE is consistent with the intent of the site.
  • As owner of the property, Manatee County is entitled to recover all costs associated with preparing the Perico Preserve site to act as a mitigation site for any public agency.  Manatee County staff has calculated the value of the mitigation opportunities at Perico Preserve at a value of approximately $351,000 per acre.  Please see attachment 1.  It is anticipated the agreement between Manatee County and the City of Sarasota will include a payment schedule by the City to the County to reflect this value per acre times the acreage required by the City to offset seagrass impacts from their beach renourishment project. 
  • The Florida Department of Environmental Protection (FDEP) has requested that Manatee County Board of County Commissioners express in writing its intentions to enter into an agreement with the City of Sarasota and U.S. Army Corps of Engineers (USACE) to provide compensatory seagrass mitigation at the County’s Rookery at Perico Seagrass Advance Mitigation site.  The wording of the attached letter expressing this intent has been coordinated with the City of Sarasota, FDEP, and the Army Corps of Engineers to ensure that it accurately represents the requirements of Manatee County by FDEP and is attached for your review.
