Reconnaissance Mitigation Work entails three stages: 1. CORAL RELOCATION 2. SPONGE RELOCATION 3. SEAGRASS RELOCATION Submitted into the public record in connection with item PA.1 on 07/10/14 City Clerk MARINA CONSTRUCTION: MITIGATION STAGE Conditions to commencement of mitigation work: May 13, 2014: State Waiver Secured May 14 2014: Ocean Consulting Kick-off Meeting with U.S. Army Corps of Engineers May 15, 2014: Ocean Consulting Kick-off Meeting with DERM (PERA) May 21, 2014: Ocean Consulting Kick-off Meeting with SFWMD Submitted into the public record in connection with item PA.1 on 07/10/14 City Clerk MARINA CONSTRUCTION: MITIGATION STAGE May 22, 2014: Commencement of Mitigation Work Survey of the bulkhead was conducted: 1,200 feet from point zero. The locations of all corals were marked along the bulkhead. Measurements of each coral head and general observations were recorded. Submitted into the public record in connection with item PA.1 on 07/10/14 City Clerk MARINA CONSTRUCTION: MITIGATION STAGE Over 60 specimens of the hard coral species Oculina diffusa were identified. The corals were attached to concrete blocks with marine grade epoxy. The blocks served as a weighted base for the corals during transport to their new locations. Submitted into the public record in connection with item PA.1 on 07/10/14 City Clerk MARINA CONSTRUCTION: MITIGATION STAGE 27 coral colonies of Oculina diffusa were relocated. Note that permit conditions stipulated the removal and relocation of 14 specimens. 18 blocks with epoxied corals were relocated to the opposing shoreline (adjacent to the new art museum). 9 coral heads were too large to epoxy to blocks so they were attached directly to the riprap boulders along the shoreline. Submitted into the public record in connection with item PA.1 on 07/10/14 City Clerk MARINA CONSTRUCTION: MITIGATION STAGE The map below shows all habitats within the project site.

Note that permit conditions stipulated the removal and relocation of 30 specimens. Sponges were attached to concrete blocks with marine grade epoxy. Once the epoxy had cured, the sponge/blocks were transported to the relocation site on the north side of the McArthur Causeway. Submitted into the public record in connection with item PA.1 on 07/10/14 City Clerk MARINA CONSTRUCTION: MITIGATION STAGE June 30, 2014: Seagrass mitigation, the last stage of the reconnaissance mitigation work began. • 2000 plugs are being removed and transported to a temporary holding site, north of the Julia Tuttle Causeway. --"` When the dredging phase of the marina construction is completed and the dredge holes are filled, these plugs will be replanted in the filled dredge hole. We have identified additional donor locations whereupon 8,000 plugs will be removed and replanted within the filled dredge hole (i.e. mitigation site).

MARINA CONSTRUCTION: MITIGATION STAGE July 11, 2014: Anticipated completion date of Mitigation Work required prior to bulkhead stage and dredging stage • Mitigation will continue throughout the marina project with the Brickell artificial reef mitigation anticipated to begin October, 2014 through February, 2015. • The Brickell Mitigation Site is for the creation of an artificial reef. The artificial reef will most likely be constructed of limestone boulders or concrete reef balls. It is to off -set impacts to hard -bottom habitat at the project site. This Brickell Artificial Reef will result in a net -increase of hard bottom habitat — as we are required to create more suitable habitat than impacted.
