2.3.4.1 Intetidal
Figure 2-3 shows biological resources in the vicinity of the Oil Piers site. Intertidal
substrate at the Oil Piers beach placement site is sand. A significant rocky intertidal
area is found approximately 1,200 ft. to the west of the site at Mussel Shoals off Punta
Gorda. The intertidal habitat consists mainly of large boulders and cobble. Extensive
surf grass meadows coat the rocks in the lower intertidal. Green sea anemones and
California mussels are also abundant (Tway 1991).
2.3.4.2 Subtidal
The subtidal substrate in shallow depths (8 to 15 ft.) off the Oil Piers sand placement
site consisted of scattered rocks between 4 and 12 inches high at the western end. To
the east, most of the shallow subtidal area was sand. At the southeastern end, the
remnants of the oil piers are still there and provide some shelter for fishes and
attachment for sessile invertebrates.
Some patches of kelp have been mapped southeast of the Oil Piers site (Ecoscan
1989). During the August, 2000, survey, a small patch of kelp was observed in about
25 to 30 ft. of water offshore the downcoast end of this site.
2.3.4.3 Wetlands
No tidal wetlands occur near the Oil Piers beach placement site.
2.3.4.4 Sensitive Species
The federal and state endangered California brown pelican commonly feeds in
nearshore waters off Oil Piers as do several bird species (common loon, double-crested
cormorant, California gull, elegant tern) that are California Species of Special Concern.
2.3.4.5 Other Sensitive Biological Resources
No sensitive biological resources other than those described above are typical of the Oil
Piers site.
