Pier Demolition The existing structure will be demolished using land and water-based construction equipment. The surface structures, including the Inverted Pyramid, retail area, landscaping, pavers, and asphalt paving, will be removed and taken to approved landfills or recyclers. The remaining steel reinforced concrete substructure, comprised of the pier deck, pile caps, and piles, will be taken to approved landfills or recyclers or will be used to construct a shoreline stabilization revetment at Albert Whitted Airport. Following deployment of turbidity barriers around the active construction area, the pier deck will be demolished or cut into smaller segments to be lifted using cranes located on the adjacent deck area or on barges. The connections between the pile caps and piles will be demolished or cut, and the reinforcing bars cut to release the pile caps from the piles. The majority of the piles supporting the existing pier will be cut off at an elevation 1 ft. below the mudline. Both the deck and the pile caps will be transported to the Uplands for processing and disposal. Piles in the vicinity of the proposed marina will be extracted in their entirety and piles in the proposed reef area will be cut off approximately at mean lower low water elevation for reuse in supporting the proposed reef, or if determined to be unsuitable for re-use, will be cut off at an elevation 1 ft. below the mudline. Cut-off piles will require localized disturbance of the bay bottom to provide access to the cut-off elevation. Piles to be fully extracted will utilize water and air jetting along the pile to release it from the bay bottom. Existing 20-ft. by 20-ft. concrete foundation caissons, supporting the Inverted Pyramid and glass elevator structure, will remain undisturbed. The new design intends to reuse the caissons. Albert Whitted Airport Shoreline Stabilization The eastern shoreline of the Albert Whitted Airport is comprised of approximately 2,500 linear-ft. of bulkhead, which is degraded with areas of wall collapse and significant loss of soil in several locations. Clean cementitious material from the demolition of the existing pier will be transported by truck or barge from the pier to the airport shoreline and used to construct a shoreline stabilization revetment. The concrete will be clean of asphalt and other materials found on the existing pier and will be processed into pieces ranging from 2 ft. to 6 ft. in the longest dimension. Reinforcing steel will be cut off flush to the face of the concrete. With turbidity barriers in place, material will be dumped from the shoreline by trucks or will be removed by crane from barges. Barges will be prohibited from entering the existing seagrass beds along the shoreline. MICHAEL MALTZAN ARCHITECTURE, INC. 3 - 137
BASIS OF DESIGN BOOK 1 3 GENERAL PLANNING CRITERIA PERMITTING AND DEMOLITION (continued) The shoreline stabilization revetment extends approximately 32 ft. from the existing shoreline and will impact approximately 1.8 acres of bay bottom. The revetment toe will be located a minimum of 24 ft. landward of existing seagrass beds. Water Quality Monitoring The active work areas will be encompassed by turbidity curtains to contain any turbidity generated during demolition or construction. Turbidity will be monitored daily by an independent 3 rd party during construction activities at a “downstream” location 500 ft. outside of the turbidity barrier and at a baseline location away from the construction area. Construction will be suspended when turbidity readings exceed 29 NTU’s above the background reading until readings are within the 29 NTU limit and the source of the elevated turbidity is rectified. Pier Structure Environmental Considerations The St. Petersburg Pier is located in the Pinellas Aquatic Preserve in Tampa Bay. This area is designated as an Outstanding Florida Water (OFW). The City of St. Petersburg owns the submerged lands around and under the existing and proposed Pier. Shading Currently, the Pier shades approximately 230,000 sq. ft. of bay bottom. The existing structure is a minimum of 100 ft. wide up to 300 ft. wide with a structure bottom elevation of approximately 5 ft. above MSL. The proposed Pier reduces overwater shading by 60%, shading approximately 93,000 sq. ft. of bay bottom, with width ranging from 10 to 20-ft. The 10-ft. wide Overwater Bridge portion of the Pier has a bottom structure elevation of approximately +25 ft. above MSL and is not expected to permanently shade bay bottom. Number of Piles The existing Pier has approximately 1,500 piles supporting the pier approach, pier head, and boat docks. The Inverted Pyramid and glass elevator are supported by five (5) 20-ft. square concrete caissons. The proposed Pier has approximately 430 piles associated with the Overwater Drive, Overwater Bridge, and Canopy. The proposed Underwater Feature includes the potential reuse of an additional 130 existing piles or the install of new piles to support the reef infrastructure. Seagrass Existing seagrass beds are located near the shoreline in water depths ranging from 4 to 9 ft. No seagrass was identified in the 100-ft. wide area where the existing Pier crosses these depths. Construction barges will be prohibited from approaching within 20-ft. of the existing seagrass beds. The new Pier includes two structures crossing the seagrass habitat area including the 20 ft. wide Overwater Drive with deck at elevation +12 ft. above MSL and one 10 ft. wide “walking 3 - 138 THE NEW ST.
