<br />Wetland excavation and replacement will occur simultaneously to minimize transplant shock and <br />increase success in reestablishing wetland vegetation. The 1.05 acres of wetlands occurring in the <br />Phase I area and Processing Site will be transferred directly into the prepared wetland bench <br />creating 1.6 acres of constructed wetlands under the Phase A operative. Wetland vegetation and <br />soils from the Phase I and Processing Site areas will be evenly distributed over the Phase A <br />mitigation area. Project mitigation using this type of strategy is advantageous in that it avoids <br />temporal wetland losses and increases net site acreage of wetland habitat. <br />Table 1.

Basin <br />containment volume will be controlled by a pipe positioned to stabilize water level at same <br />elevation of constructed wetland bench. A sediment fence, erected and maintained around bench <br />sections bordering detention pond, will be used to minimize silting of emergent wetland <br />vegetation. Low turbidity water removed from upper pond surface will be discharged into river at <br />peak volume. A flap-gate installed at the end of pipe prevents backflow from river. <br />2-3 <br />
