5. Environmental Analysis
maintenance would continue. These activities could have short-term,
minor adverse effects, but to a lesser degree than the action alternatives.
• Alternative 2 proposes the fewest additional features and facilities of the
three action alternatives. Minor removal or other disturbance of native
vegetation could result from expanding the group picnic facilities at San
Luis Creek Use Area and the campground at Los Banos Creek Use Area,
adding up to 30 tent sites at the northwestern shoreline of San Luis Creek
Use Area, and relocating the equestrian camp at Los Banos Creek Use
Area. Alternative 2 and the other action alternatives would implement a
focused vegetation management statement to allow for rehabilitation of
natural ecosystems using BMPs (described in detail in Section 4.4.2),
which would have a beneficial impact that would not be realized under
Alternative 1. Alternative 2 and the other action alternatives would allow
for reopening or relocating the boat launch at Medeiros Use Area and
exploring engineering solutions for shallow-water areas in O’Neill
Forebay, including dredging and removal of sandbars. These activities
have the potential to temporarily or permanently affect wetland vegetation
if any is present. Minor adverse effects to vegetation caused by
maintenance, expansion, or construction from Alternative 2 would be
greater than from Alternative 1 but less than from Alternatives 3 and 4.
Prudent siting of new facilities and implementation of other measures such
as those described in Section 5.4.3.4 would reduce potential impacts to
minor.
• Alternative 3 would allow for additional camping facilities at all of the use
areas, including alternative overnight lodging such as cabins or yurts at
Basalt and San Luis Creek use areas. This alternative also provides for
new or expanded day use facilities such as 30 shade ramadas at Dinosaur
Point Use Area; a new boarding float, ADA-accessible fishing pier, and
additional group picnic facilities at San Luis Creek Use Area; and shelter
and restrooms at Medeiros Use Area. The proposed improvements would
not overlap with CNDDB-recorded occurrences of special-status plants
(Map 6g) or habitat communities (Map 6h), wetlands recorded in the
National Wetland Inventory (Map 6a), or vernal pool habitat recorded in
Holland 2009 (Map 6b). In addition, these facilities would be primarily
sited in FC Zones, where development is already present; therefore, no
major adverse impacts to vegetation are anticipated. Like Alternative 2,
Alternative 3 would also allow for reopening or relocating the boat launch
at Medeiros Use Area and dredging/removing sandbars in shallow-water
areas in O’Neill Forebay, and in addition would expand the boat launch at
San Luis Creek Use Area. These actions have the potential to temporarily
or permanently affect wetland vegetation if any is present. Minor to major
adverse effects to vegetation could result from Alternative 3, but prudent
siting of new facilities and implementation of other measures such as
those described in Section 5.4.3.4 would reduce potential impacts to
minor.
