Ramona Hog Lake Road Improvement Project August 2011<br />
As illustrated in Figure 5, a 10’ x 5’ double box culvert is proposed at <strong>the</strong> crossing of<br />
<strong>the</strong> existing <strong>road</strong> with <strong>the</strong> intermittent blue-line stream to provide all-wea<strong>the</strong>r access.<br />
This culvert is designed to BIA requirements <strong>for</strong> a 25 year flood event. The design will<br />
require a site specific Forest Plan amendment in order to accommodate <strong>the</strong> smaller<br />
BIA design, as <strong>the</strong> Forest LMP calls <strong>for</strong> culverts designed to accommodate 50 year<br />
events (page 19 and 20 of 33). The amendment will apply only to this area of this<br />
<strong>project</strong>. Only very minor <strong>road</strong> cuts and fills will be required except at <strong>the</strong> box culvert<br />
structure. Paving and re-designing of <strong>road</strong> structures will occur in such a way as to<br />
minimize <strong>environmental</strong>, economic, and social impacts on <strong>the</strong> surrounding area, and<br />
meet <strong>the</strong> requirements of NEPA.<br />
National Forest Road 6S18 (Hog Lake Road) is <strong>the</strong> only potentially year round System<br />
<strong>road</strong> with a direct connection from <strong>the</strong> Reservation to a dedicated year round County<br />
Road (Bautista) outside <strong>the</strong> Forest boundary. The great majority of paving would<br />
occur on encumbered land which is already in use as <strong>the</strong> existing unpaved <strong>road</strong>. Hog<br />
Lake Road has an average width of approximately 30 feet, and <strong>the</strong> proposed paved<br />
<strong>road</strong> would be 22 feet in width with 2 foot shoulders. Except in <strong>the</strong> relatively small area<br />
where <strong>the</strong> 10’ x 5’ double box culvert structure would be installed, no <strong>road</strong> widening<br />
and very minimal grading would be required.<br />

New easements will be granted by and to <strong>the</strong> BIA, Ramona Tribe, Forest Service, and<br />
<strong>the</strong> owner of APN 572-050-048, which is a parcel of land located between <strong>the</strong> Ramona<br />
Tribe’s privately held parcel of land and National Forest Land. Newly created<br />
easements that fall within <strong>the</strong> Project area include <strong>the</strong> following (see Figure 3):<br />
A non-exclusive public <strong>road</strong> easement over those parts of Hog Lake Road<br />
passing over National Forest Land will be granted by <strong>the</strong> Forest Service to<br />
