0137im.jpg){kind=tracking} 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
blade length of surfgrass, and
density of kelps and large invertebrates.
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 rocky intertidal habitat, subsequent
beach fill activities at Ash Avenue shall be modified in a way to prevent deposition of
sand on the rocky intertidal habitat at Carpinteria State Beach.
4.2.2.3 Carpinteria Creek
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.
4.2.3 Oil Piers
4.2.3.1 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 following:
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.
The survey shall be repeated following beachfill operations of 30,000 cubic yards or
more and again at the end of the summer season during the period of maximum sand
cover. Based on dispersion studies by Moffatt & Nichol Engineers a beach fill of less
than 30,000 cubic yards would not produce enough material to be discernible beyond
the area of immediate fill. If project-generated sand deposition is observed to be
affecting adversely the reef, subsequent beach fill activities at Oil Piers shall be
modified in a way to prevent deposition of sand on the kelp bed. 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 will be required (see Section 4.3 below).
