All dewatering activities will take place outside of the Buffer zone and oak stakes will be used instead of live stakes. Questions and comments from the commission: The commission asked why the plans were not stamped. Mr. Potsma explained that the final engineering plan will be stamped by the engineer. The commission stated that they did not think a 1:1 wetland replication would be sufficient. They were concerned about what would happen if there were problems with some of the plants. Mr. Postma stated that the wetland restoration will be 1:1, but the replicated stormwater wetland will make it a 2:1 ratio. The applicant explained that they could shift the replicated stormwater wetland slightly to enlarge the wetland restoration area. The commission requested that more detail be added to the plan including the edge of pavement line, the retaining wall, and the infiltration trench dimensions and widths. The commission asked for detail regarding the geo-grid.
