Additionally, Mr. Gadd has analyzed coastal processes at a number of sites to determine on-going shore erosion rates in order to select appropriate exclusion zones for coastal facilities. He has provided survey support for the installation of subsea pipelines through the winter ice at four sites in Alaska and Russia.

In Southern California, Mr. Gadd’s experiences include an analysis of wetlands enhancement and habitat creation
 
at Upper Newport Bay and evaluations of coastal processes along the coasts of Orange and San Diego Counties. To quantify sand motion along the coast, he has performed fluorescent sand tracing studies at Crescent Bay, Laguna, and Ballast Point in San Diego Bay.  
 
Mr. Gadd began his career as a NOAA Commissioned Officer participating in bathymetric survey programs and coastal sediment studies in Alaska, California and the East Coast of the United States.

Mr. Gadd has served as expert witness for the California Attorney General’s Office in litigation pertaining to the determination of coastal property boundaries in Malibu. He recently served on an international committee convened under ISO 19906 to develop standards for man-made islands. He was a contributing author of the ASCE monograph entitled Arctic Coastal Processes and Slope Protection Design. He has lectured at the University of California and Oregon State University and serves as a Director of the California Shore and Beach Preservation Association.

GREG HEARON, P.E. PRINCIPAL  
 
B. S., Ocean Engineering (Florida Institute of Technology, 1993)
M.S., Civil/Coastal Engineering (Oregon State University, 1995)


Mr. Hearon has extensive experience in the fields of coastal engineering, coastal oceanography, and oceanographic data acquisition. His project involvement includes field data acquisition and analysis, project design, construction advisory, and performance monitoring. He routinely undertakes both office and field studies for projects in both temperate and Arctic environments. Areas of particular interest include coastal processes, large scale physical modeling, structural and non-structural means of coastal protection, and beach nourishment performance.

He has worked with SANDAG and constituent coastal cities since 1996 to assess the condition of San Diego County’s beaches and coastal lagoon entrances, and to evaluate the impact of both natural events and human intervention. Since 2001, particular influence has been placed on the outcome of the Regional Beach Sand Project, which resulted in the placement of 2.1 mcy of sand nourishment on the region’s beaches. While serving as the project engineer for the Corp’s Coast of California Storm and Tidal Waves Study - Orange
 
County, Mr. Hearon analyzed beach and nearshore survey data encompassing a 32-year period to quantify historical shoreline and volume changes in the Huntington Beach and Seal Beach Littoral Cells. The study included a comprehensive evaluation of beach nourishment operations at Surfside-Sunset and West Newport and the development of a budget of sediment.  
 
As the project engineer for several pipeline route surveys in the Alaskan Beaufort Sea, Mr. Hearon supported side-scan sonar and multi-beam data collection, and was responsible for data reduction and interpretation. Objectives of these surveys included mapping and evaluating the frequency and severity of strudel scouring and ice gouging on the seafloor. Mr. Hearon recently served as a Principal Investigator for a study designed to map the annual extent of peak river overflooding onto the landfast ice of the Alaskan Beaufort Sea. The work included an assessment of strudel drain and strudel scour potential associated with river overflood based on an analysis of data obtained by Coastal Frontiers for more than twenty industry studies.

Mr. Hearon is a member of the American Shore and Beach Preservation Association. He was a co-author for the California Beach Restoration Study. As a certified SCUBA diver, he has performed underwater inspections and deployed oceanographic instrumentation both in California and the Alaskan Arctic. He is a licensed professional engineer in the states of California and Alaska.

Since joining Coastal Frontiers, Mr. Richmond has acquired considerable experience in the disciplines of coastal engineering, nearshore data acquisition, and construction advisory. His areas of particular interest include coastal engineering design, physical model studies, construction advisory, and coastal processes.

Mr. Richmond has participated as project engineer for the design and installation of the slope protection systems for several oil production islands and coastal pads in the Alaskan Beaufort Sea. Mr. Richmond also provided survey and engineering support during the installation of the subsea pipelines which service these offshore facilities. Additionally, Mr. Richmond has served as the project manager for coastal erosion studies at Pt. McIntyre near Prudhoe Bay, Alaska. These studies have included both historical air photo analyses as well as annual ground survey programs to assess nearshore erosion at an abandoned DEW Line Station. Similarly, he has served as project engineer on several other coastal erosion programs in the Alaskan Arctic. He participated in a bathymetric study of an extensive region of the Alaskan Beaufort Sea to determine safe and efficient routes for large barge navigation.
 
 
In Southern California, Mr. Richmond’s experience includes serving as project engineer for ongoing beach monitoring programs conducted on behalf of BEACON, SANDAG, and the cities of Carlsbad, Encinitas, Newport Beach, and Solana Beach, CA. In addition to participating in each of the bi-annual field survey programs, he has served as the primary engineer responsible for the data processing, analysis, and presentation of results derived from the field activities. Mr. Richmond recently worked as a project engineer for the removal of Pratte’s Reef, where his responsibilities included permit acquisition and the direction of on-site construction activities for the removal of the artificial surfing reef near Marina Del Rey, CA.

CHRISTOPHER P. SCOTT, P.E. COASTAL ENGINEER  
 
B.S., Ocean Engineering (Texas A&M University, 1999)
M.S., Coastal and Ocean Engineering (Oregon State University, 2005)


Mr. Scott specializes in the fields of coastal engineering, nearshore data acquisition and analysis, and numerical modeling. His responsibilities include bathymetric data collection and analysis, coastal engineering design, numerical modeling of coastal processes, and construction advisory.

Mr. Scott has worked on a number of coastal and nearshore monitoring studies in Southern California. These include the semi-annual beach profile monitoring programs conducted on behalf of SANDAG, and the cities of Carlsbad, Encinitas, Newport Beach, Santa Barbara, and Solana Beach, CA. In addition, he directed a lagoon monitoring program in support of the re-design of a storm drain near Oxnard, CA. The monitoring program included bathymetric, water level, and salinity data collection within the coastal lagoon and along the beach. In each program, Mr. Scott’s responsibilities have included bathymetric data collection, reduction, and analysis.
