Recreation Recommendations R1 Implement localized trail improvements to create a more accessible, maintainable and environmentally sensiƟve trail from the exisƟng Cowles Mountain staging area to the summit. If localized improvements prove inadequate, then a full trail reroute should be evaluated. R2 Assess a secƟon of the Barker Way trail for localized improvements to address trail steepness and erosion issues. If localized improvements are inadequate or infeasible, then this secƟon of trail should be rerouted. R3 Develop and implement a public access boundary with fencing and signage at the top of Cowles Mountain to reduce habitat impacts. Restore naƟve habitats outside the defined boundary. R4 Close and restore the exisƟng hike/bike and unauthorized user created trails extending from the Cowles Mountain service road to the Barker Way Trail. R5 Close and restore the hike/bike trail extending from Wingspan Drive to the Barker Way Trail. R6 Construct a new trail alternaƟve to avoid a parƟcularly steep secƟon of the Cowles Mountain service road. R7 Close and restore the exisƟng hiking and unauthorized user created trail on the eastern slope of Pyles Peak. R8 Close and restore a series of interconnected exisƟng hiking trails on the eastern slope of Cowles Mountain. A porƟon of these trails are within the California gnatcatcher CriƟcal Habitat designated by the USFWS. R9 Assess a secƟon of the Big Rock trail for localized improvements to address trail steepness and erosion issues. If localized improvements are inadequate or infeasible, then this secƟon of trail should be rerouted. R10 Close and restore the exisƟng hiking trail located immediately behind the homes along Big Rock Road. R11 Construct a new trail connecƟon from the Padre Dam water tank to Big Rock to create a porƟon of a large loop on the east side of Pyles Peak and north side of Cowles Mountain. R12 Construct a new trail connecƟon from the Padre Dam water tank to the staging area in CM-F2 to create a porƟon of a large loop on the east side of Pyles Peak and north side of Cowles Mountain. R13 Close and restore an exisƟng hiking trail along the ridge north of Pyles Peak. R14 Assess a secƟon of the exisƟng Pyles Peak trail for localized improvements to address trail steepness and erosion issues. In-trail grade reversals and reestablishment of outslope should be adequate soluƟons. R15 Close and restore the exisƟng hiking trail from Pyles Peak down to Golf Crest Drive. R16 If the staging area in CM-F2 is implemented, construct a new connector trail from it up to the exisƟng Pyles Peak trail. R17 If the staging area in CM-F2 and the trail in CM-R12 are implemented, evaluate providing rock climbing access to the western face of Pyles Peak by construcƟng a new trail from the exisƟng Pyles Peak trail. Impacts to bat roosts will need to be evaluated; signage and access controls will be required at the top of the climbing faces to control unauthorized access to the top of Pyles Peak; and an emergency response plan will need to be coordinated with San Diego Fire and Rescue. Facility Recommendations F1 Plan, design and implement an off-street gravel or decomposed granite surfaced parking area with street improvements that comply with public road standards as applicable, at the Barker Way entrance to reduce some of the parking demand on the local residenƟal streets and provide a more formal trailhead and potenƟal for a maintainable comfort staƟon. Ensure that temporary construcƟon impacts associated with parking lot improvements do not affect adjacent neighbors and park users. F2 Collaborate with SDCWA to plan, design and implement an off-street gravel or decomposed granite surfaced parking area just north of Golfcrest Drive off Mission Gorge Road adjacent to the SDCWA pipeline access portal. This will provide northerly access (CM-R15) to the Pyles Peak trail and a potenƟal rock climbing area (CM-R17). Access from Mission Gorge Road would be a right turn in and right turn out only. Ensure that temporary construcƟon impacts associated with parking lot improvements do not affect adjacent neighbors and park users. F3 Plan, design and implement improvements in collaboraƟon with the City of Santee to the disturbed shoulder within the public right of way along Mesa Road near Big Rock Park to provide addiƟonal parking spaces and a linear bike skills area. Ensure that temporary construcƟon impacts associated with parking lot improvements do not affect adjacent neighbors and park users. F4 Relocate the parking at the south end of Mesa Road as part of CM-F3 and revegetate the exisƟng parking area while maintaining the trailhead kiosk and gate. F5 Add interpreƟve signage along the ridgeline trail from Cowles to Pyles Peak, orienƟng the public to the visual panorama and explain how a view can be interpreted from different “perspecƟves” – for example, as an acƟve city full of different uses, nodes, and landmarks linked by circulaƟon; as a landform resulƟng from long-term geological and hydrological processes; and as the historical accumulaƟon of arƟfacts tracing man’s interaction with his environment. F6 When funds are available, and technological advances allow for minimizaƟon of equipment, the City and County antennas should be modified for a less visible profile, or be removed. Any modificaƟons to the faciliƟes will be coordinated through the City’s Deputy Director of CommunicaƟon and Networks and the County’s Manager of Microwave/Radio CommunicaƟons. *The City of San Diego will be responsible for all improvements within the Cowles Mountain area as idenƟfied in the Master Plan and per the Joint Powers Agreement with the County of San Diego Regarding the OperaƟon and Maintenance of Tijuana River Valley Park and Mission Trails Regional Park. Any recreaƟonal amenity and its management, or subsequent projects proposed within the County owned Cowles Mountain area will require analysis and review by the County on a project by project basis.
