2015 Shoreline Mapping Presentation
The results of New Hanover County’s 2015 shoreline mapping program were provided by
representatives from the contractor Moffatt and Nichol Engineering. Representing the firm’s
Raleigh office was Nicole Vanderbeke and representing the newly established Wilmington office
was Robert Neal. The presentation was well received with insightful questions from the PWBC.
A pdf of the power point presentation is attached.
Vice-chair Andrew concluded the presentation with three questionsthat centered on the average
annual background erosion rateof-5.6 cubic yard/foot/year(cy/ft/yr)system wide (Slide 15,
WithoutCSDR, Total).
Question:Is there a cost/cubic yard rule of thumb?
Response:$12-$15/cubic yard inclusive of mobilization and demobilization.
Question:What does the -5.6 cy/ft/yr equate to in total cubic yards system wide?
Response:Over the 116,736 linear feet of shoreline assessed, the average annual loss system
wide is approximately 650,000 cubic yards.
Question:Is there a rule of thumb comparing cubic yard loss to perpendicular linear beach
loss?
Response:There is a calculationand a rule of thumb that is provided in the NC Beach Inlet
Management Plan for the entire stateof1.3 cubic yards of volume change equates
to one perpendicular linear foot of shoreline change.
