"Water dependent industry" means those commercial, industrial or manufacturing activities which, for purposes basic to their existence must occur or locate on or adjacent to the estuaries, sounds, channels, shores or marshlands of the coast. "Suitable sites for water dependent industry" means those areas of land which are suitable for the development of water dependent industry because of their proximity to waters of navigable depth, size and configuration, topography, soil conditions and access to other means of transportation. After consultation with local governments, port authorities, development commissions, port and harbor commissions and other interested parties, and after full consideration of zoning ordinances duly adopted by local governments, the department shall designate those sites it deems suitable for water dependent industry. The definition of "suitable sites for water dependent industry" shall be limited to, but not necessarily inclusive of, waterfront sites owned by county port authorities, development commissions and port and harbor commissions, and to areas that are now or are later made to be within one thousand (1,000) feet of the centerline of any natural or maintained channel having a depth of seven (7) feet or greater at mean low water. However, additional sites may be included in the definition of suitable sites for water dependent industry with the concurrence of the board of supervisors in the county affected.
(j)
"Ordinary High Water Mark (OHWM)" means a mark on the shore determined by the department staff, established by fluctuations in water level and indicated by physical and biological characteristics including, but not limited to, water stains, changes in the character of the soil, scour lines, presence of debris lines, changes in plant communities and other appropriate means that consider the characteristics of the surrounding area. The determination of OHWM shall not be made by the department staff during high tide where the above referenced characteristics are not observable. OHWM is not the same as mean high water and shall not be used for determination of the boundary between private property and public trust tidelands or for any purpose other than regulated activity as defined in this section.
