Conventional land excavators, motor graders, and dump trucks would be used to
achieve the desired elevations and excess material would be removed to an appropriate
offsite location. The restoration proposals in Alternative C include 11 acres of restored
coastal sage scrub. Little, if any, earthwork would be required to prepare these areas
for restoration. All of the restoration proposals in Alternative B would require some
level of earthwork, with the greatest volume of cut occurring in areas proposed for
intertidal salt marsh and mudflat habitat. As a result, the amount of grading necessary
to implement Alternative C would be considerably less that that required for
Alternative B. The specific details regarding volumes of cut and fill and overall site
design and grading would be provided during the preparation of preliminary and final
restoration plans and construction specifications.
Once grading has been completed and the desired elevations have been achieved,
native plants appropriate to the range of elevations present at each site would be
installed to supplement natural species recruitment. Areas proposed for
wetland/upland transitional and coastal sage scrub would require the greatest density
of installed plant material. Wetland/upland transitional habitat and coastal sage scrub
habitat would be planted in the fall when temperatures are cooler and the likelihood for
precipitation is higher. The native wetland/upland transitional vegetation would
consist of species such as alkali heath, estuary seablite, alkali weed, salt grass, sea
lavender, and shore grass. The primary components of the coastal sage scrub habitat
would include flat-top or California buckwheat, California sagebrush, lemonade berry,
coyote brush, coast sunflower, white sage, and coastal goldenbush. Soil amendments
and a moisture gel packs would be used as described under Alternative B.
Under this alternative, the non-native vegetation on the four highest mounds of the
eastern-most island in Case Road Pond would be removed and the sites topped with
