�oz!"i <br />Tangent Pier vs. Sheetpile Construction <br />The standard construction technique at water's edge involves sheetpiles that are driven into the <br />earth. The applicant would use the Tangent Pier construction technique for the 7,000-foot <br />container wharf to potentially reduce both water quality and noise impacts. <br />North Shore Noise Wall <br />A 20-foot pre -cast concrete wall has been designed to reduce the potential noise impacts to the <br />North Shore Communities (Sheets 18 and 19). Additionally, there would be enhancement <br />planting to ensure at least three trees every 20 linear feet on the North side of the wall. It is <br />intended that Loblolly Pines would be planted where needed (Sheet 19). <br />Spreader Bars <br />To further reduce the potential noise impacts to the North Shore communities, the PHA is <br />committing to installing impact noise reductions system on all wharf crane spreader bars utilized <br />at Bayport. <br />
