Harbors and Marinas

Supporting harbor and marina operations and development.

For more than 20 years, we have assisted port, harbor, and marina managers with regulatory compliance requirements.

We have an excellent working relationship with many of the regulatory agencies, including the California Coastal Commission, US Army Corps of Engineers, Regional Water Quality Control Boards, US EPA, and California Department of Fish and Wildlife. Tenera’s staff of ecologists and biologists provide their clients with innovative and cost-effective solutions to complex projects. Tenera has successfully completed numerous projects within ports, harbors, and marinas throughout the West Coast and has extensive experience characterizing existing conditions for eelgrass, fishes, benthic infauna and macroinvertebrates, as well as invasive (non-native) species.

Our other expertise includes storm water permitting, collection and analysis of sediment and water quality samples, current flow measurement and modeling, mapping and inspection of highly turbid submerged environments using side scan sonar and Didson camera, hydrodynamic modeling of marina sediment accretion and deposition, and wetlands delineation. Tenera has a full complement of instrumentation for all aspects of field data collection including GPS equipment to allow an accurate depiction of the sampled locations and integration with GIS mapping software.
