TABLE XX
Cuyamaca Mountains State Wilderness
Proposed Boundary Adjustments
NOTE: Reference numbers on this Table correspond with numbered call‐outs on “Figure 15 – Cuyamaca
Mountains State Wilderness Proposed Boundary Adjustments”
Since the Cuyamaca Mountains State Wilderness was established in the park in 1982, several conflicts
with the wilderness boundaries have been discovered which have caused confusion with trail users,
inconsistent enforcement of wilderness regulations, and an unintended loss of trail connectivity for
mountain bikers. These conflicts include existing multi‐use trails and utilities in wilderness, as well as
wilderness boundaries adjacent to fire roads, trails, and park boundaries that are not based on any
consistent standards. This has precipitated the need to establish consistent wilderness boundary
standards and an adjustment of some wilderness boundaries to better reflect current management
practices and visitor uses. Guidelines are presented in the General Plan which establish viable standards
for wilderness boundaries, adjusts wilderness boundaries to remove utilities and existing multi‐use
trails, and makes possible future multi‐use trail connections.
Wilderness boundaries are proposed to be adjusted in the following areas and ways (with justification
following). The total combined reduction in wilderness acreage after the following boundary
adjustments is 672 acres:
1. At paved roads (e.g., State Route 79 (SR 79), Engineer’s Road): 50’ from centerline of road (total of
100’).
Need consistent standard for boundary identification and GIS mapping.
Caltrans easement is already 40’ from centerline of road (total of 80’).
10 extra feet from Caltrans easement would provide buffer from any Caltrans or State Park
maintenance operations.
2. At dirt roads (i.e. fire roads): 100’ from centerline of road (total of 200’).
Need consistent standard for boundary identification and GIS mapping.
Would provide appropriate buffer for any needed road realignment, or road and brush
maintenance adjacent to dirt road.
3. At perimeter park boundaries: Contiguous with park boundary.
Need consistent standard for boundary identification and GIS mapping (boundary has been
inconsistently interpreted).
No buffer needed between wilderness boundary and park boundary.
Contiguous wilderness and park boundaries would avoid possible confusion and reduce the
need for signage.
4. At park boundaries with inholdings: Contiguous with park boundary.
Need consistent standard for boundary identification and GIS mapping.
No buffer needed between wilderness boundary and park boundary.
Contiguous wilderness and park boundaries would avoid possible confusion and reduce the
need for signage.
5. At dirt road to old quarry (intersects with SR 79 and travels westward from Lake Cuyamaca):
Cherry stem 100’ from centerline of dirt road (total of 200’).
Consistent with buffer for dirt roads
Park access needed for operations
6. At SDGE electrical line easement and dirt access road to power poles: Decommission wilderness
from 100’ from south side of SDGE easement northward to Upper Green Valley Fire Road and La
Cima Fire Road (reduction of 284 wilderness acres).
Access required by SDGE for existing easements that predate wilderness.
North of SDGE easement is an access road used by SDGE to access power poles – this would
also be decommissioned from wilderness.
Consistent with buffer for dirt roads
7. At Green Valley on east side of SR 79 between the School Camp and Dyar House to the north, East
Side Trail to the east, and Sweetwater Parking Lot to the south: Decommission wilderness
(reduction of 195 wilderness acres).
Existing SDGE easement and power lines run through the area that predate wilderness.
Area adjacent to and visible from SR 79 (noise, visual intrusion)
8. Harvey Moore Trail and Deer Park Trail: Maintain as wilderness area (do not decommission) and
close trails to multi‐use.
Trails were inadvertently open to multi‐use after adoption of the current 1986 wilderness
which shows the Harvey Moore Trail and Deer Park Trail in wilderness.
Area has strong wilderness values consistent with other wilderness at East Mesa.
Potential east‐west multi‐use trail connection exists with Cleveland National Forest (tying
into East Mesa Fire Road just south of Granite Springs Trail Camp).
9. Westside Trail between Japacha Fire Road and Arroyo Seco Fire Road: Adjust wilderness boundary
from adjacent to SR 79 to 100’ west of Westside Trail (reduction of approx. 34 wilderness acres).
Provides buffer between SR 79.
Provides for needed north‐south multi‐use trail connection.
Consistent with buffer for dirt roads.
10. Eastside Trail between Sweetwater Parking Lot and East Mesa Fire Road: Adjust wilderness
boundary from adjacent to SR 79 to 100’ east of Eastside Trail (reduction of approx. 45 wilderness
acres).
Provides buffer between SR 79.
Provides for needed north‐south multi‐use trail connection.
Consistent with buffer for dirt roads.
11. Blue Ribbon Trail between South Boundary Fire Road and Merigan Fire Road: Adjust wilderness
boundary from adjacent to park boundary to 100’ west of Blue Ribbon Trail (reduction of approx.
110 wilderness acres).
Provides for needed north‐south multi‐use trail connection.
Gives cyclists an alternative to riding on SR 79.
Consistent with buffer for dirt roads.
