0070im.jpg){kind=tracking} The survey shall be repeated following beachfill operations and again at the end of the summer
season during the period of maximum sand cover. If project-generated sand deposition is
observed to be affecting adversely the reef, subsequent beach fill activities at Ash Avenue shall
either be modified in a way to prevent deposition of sand on Carpinteria Reef or ceased entirely
at this site. If the project is observed to cause extensive damage to the reef resulting in a loss of
kelp plants or hard bottom habitat, additional mitigation may be required.
Rocky Intertidal Habitat off Carpinteria State Beach. The rocky intertidal habitat off
Carpinteria State Beach will be monitored for sedimentation and health. BEACON will
coordinate with researchers from the University of California at Santa Barbara (UCSB) who are
conducting a long-term monitoring program at Carpinteria State Beach. A baseline shall be
established prior to beach fill activities at Ash Avenue. The baseline will include installing
reference stakes to measure sand deposition. Permanent transects shall be established to monitor
sand height over the reef and surfgrass, percentage of sand and rock substrate along each transect,
percent cover of sand and organisms on rocks, percent cover of surfgrass, and blade length of
surfgrass.
The survey shall be repeated following beachfill operations and again at the end of the summer
season during the period of maximum sand cover. The data from the surveys will be analyzed to
identify any long-term changes from the project as well as short-term seasonal variations. If
project-generated sand deposition is observed to be affecting adversely the rocky intertidal
habitat, subsequent beach fill activities at Ash Avenue shall either be modified in a way to
prevent deposition of sand on the rocky intertidal habitat at Carpinteria State Beach or ceased
entirely at this site.
5.2.2
Physical Monitoring
The mouth of Carpinteria Creek shall be monitored during and after beach fill operations at Ash
Avenue. If sand from the BEACON South Central Coast Beach Enhancement Program is
observed to close the mouth of the Creek, BEACON will reopen the mouth with a bulldozer.
It is proposed that turbidity monitoring will be conducted during construction of the beach fills
by visual observation to ensure that the turbidity plume does not increase significantly over
ambient conditions for an extended duration and area. Beach profile surveys will be conducted
prior to and after construction of beach fill operations to track movement and retention of sand.
5.3
OIL PIERS
5.3.1
Biological Monitoring
Kelp Bed. The kelp offshore Oil Piers will be monitored for sedimentation and health. A
baseline shall be established prior to beach fill activities at Oil Piers. The baseline will include
installing reference stakes to measure sand deposition. Permanent transects shall be established
to monitor the percentage of sand and rock substrate along each transect, sand height over the
reef, percent cover of sand and organisms on rocks, density of kelps and large invertebrates,
density of life stages of kelp, and observations on health of kelp and other organisms.
