Reshape roadbeds and replace degraded culverts along upper Mountain Trail, Hayfields Trail, and Treadmill Trail at Jack London State Historic Park; remove duplicate, operationally unnecessary, degraded backcountry roads where feasible. Trails indicated are actually backcountry access roads. Mountain and Hayfields Trails, and the lower portion of Treadmill Trail, will be stabilized and continue as primary access roads; Upper Treadmill Trail will be decommissioned, with the historic footprint of the roadbed (fake full pull) left as a visible linear feature on the landscape. A new connecting trail will be constructed to connect lower Treadmill Trail with the Sonoma Ridge Trail. A one-time primary application of herbicide (Garlong 4 and Telar) will occur in the first spring following construction to prevent recruitment of weedy species; minor follow-up applications may be required to control newly recruited weeds. Work will reduce erosion, stabilize roadbase for continued vehicle use, restore natural drainage patterns, facilitate emergency access, and reduce the discharge of sediment into the South Fork of Graham Creek.
Project consists of the repair and minor alteration of existing public facilities and topographical features, involving negligible expansion of use beyond current levels, and minor alterations in the condition of land, water, and vegetation which will not involve the removal of healthy, mature, scenic trees, included as "trail or road repairs" and "trail removal, construction, or realignment" in the Department of Parks and Recreation's list of exempt activities, in accordance with CCR S15300.4.
