| Description: | Technical Report Abstract: This study gives alternatives for control of shoreline erosion at thirteen sites at Fort Eustis, Virginia. Waves are the major cause of erosion in the study area with design wave heights from 1.0 to 4.0 ft. Design stillwater levels are +5 .6 ft MLW for the 25-year return period event and +6.2 ft MLW for the 50-year return period event. A total of 13 different structures is presented for possible use at one or more sites, to yield a total of 49 structure-site alternatives. The various types of protection were categorized (low, medium, or high) according to potential environmental problems and relative cost and were assigned a numerical ranking. Advantages and disadvantages of the various types of protection are given along with a sketch for each structure-site combination. General requirements, which are applicable to all types of protection, are presented. Labor-intensive protection and/or the use of locally available materials which could result in significant cost savings are delineated. Mitigation banking, as an acceptable form of compensatory mitigation, is described. Cumulative impacts of project sediment erosion and deposition are addressed. The importance of monitoring, to determine whether permit conditions were complied with and whether the purpose of the project or mitigation is achieved, is discussed. |
