4.2.1.2 Goleta Slough Mouth

The mouth of Goleta Slough shall be monitored during and after beach fill operations at

Goleta Beach. If sand from the BEACON South Central Coast Beach Enhancement

Program is observed to close the mouth of the Slough, BEACON will reopen the mouth

with a bulldozer.

4.2.2 Ash Avenue

4.2.2.1 Carpinteria Reef

Carpinteria Reef 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 Reef. 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 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 over 30,000 cubic yards

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 Ash Avenue shall be modified in a

way to prevent deposition of sand on Carpinteria Reef. 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).

4.2.2.2 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 the

following:
