It was determined that the project was located in an area of high density for one of the two species of special concern. The dock component ofthe initial project was withdrawn from last gear's hean*ng to be considered at a later date once it was resolved with Natural Heritage. An abundance of tidewater muckets were located in the dock area which requires the acquisition of a conservation.and management permit and includes a presentation of the management plan that will allow for the protection ofthe species. Natural Heritage has issued the permit. Elements of the plan include a pre-installation survey by experts who will relocate the mussels, permanently installed footings and funding for an off-site=site research program under the direction ofl Natural Heritage and a conservation management group. Agent McManus questioned the footings. Mr. Vaccaro responded that the dock legs will be 2 inch galvanized steel posts. The concrete footing block will be one size larger at 101x1 "x1 " and form out a 2 1/2 inch diameter pipe that will extend 1 foot below the footer to use the exposed pipe to pin it to the bottom. The dock will be removed along with the ramp and float, but the footings v'll remain. Mr. Vaccaro does not anticipate that ice will e a issue due to the drop off. The Agent was pleased with the owner's efforts to identify the hest solution for the tidewater mucl ets and recommends approval for the Amended'Order. The Chair also questioned the concrete footers to which Mr. Vaccaro responded that they were a standard requirement from Natural Heritage to ensure that the dock remains in place.
