Hiking, biking and horse-riding enthusiasts converged on Lagunitas School District’s multipurpose room last Saturday to pour over maps showing proposed trail designations for seven county-owned preserves in the San Geronimo Valley. The gathering marked the first phase of implementation of the county’s Road and Trail Management Plan, which was approved by the Open Space District’s board of directors in December and delineates which trails should be designated and maintained for use on county parklands. It was the second community workshop held this year to receive public feedback on which trails should be kept for recreational access and which should be decommissioned, as well as what activities should be allowed on each trail. Dogwalking was not included on list of approved trail activities. Many of the trails were shown on the map as green lines, indicating that they will stay as is, be provided better signage and be slotted for routine maintenance and upkeep. Others, shown in red, will be decommissioned and left unkempt so that landscape may return to its natural state, though the county will not stop park-goers from continuing to forge ahead on the old trails. Trails in yellow are not currently signed or maintained, but are proposed to be opened with right-of-way constraints through lands owned by the Marin Municipal Water District. While supporting much of the county’s efforts, the San Geronimo Valley Planning Group also wondered whether newly designated trails shown on maps posted to the Internet would attract an influx of visitors, disrupting the current quiet, rural experience. A final system map will be posted on the county parks website in four to six weeks. “Our road and trail plan is designed to reflect Open Space’s mission to give opportunities for enjoying a wide range of uses,” said Supervisor Steve Kinsey, who lives in San Geronimo Valley. “Whether we come here on a bike, a horse or on foot, we have a responsibility to take care of this remarkable landscape.”
