Park Trailsby Woody Collins, Trail Crew LeaderRocky Ridge Trail Our Santa Clara County parks serve
a population of over 1.7 million Santa Clara County residents as well
as several thousand regular visitors from neighboring counties. They
provide a wide variety of educational and recreational activities.
County parks include facilities for camping, boating and fishing, disc
golf, picnicking, archery, hang gliding, golfing, and flying model
airplanes as well as a motorcycle park, a velodrome and a shooting
range, but the facilities most used by park visitors are our park
trails.
Santa Clara County Parks encompass over 44,000 acres and provide nearly 300 miles of trails that have to safely accommodate hikers, joggers, bicyclists, geocachers and equestrians. Meeting the needs of such a diverse group of users while protecting and preserving the natural landscape is difficult and involves many trade-offs. Factors that have to be considered include:
Visitor ExperienceBernal Hill Loop Trail
Providing a pleasant, safe and satisfying user experience is an
important goal for all trail design. Trails provide a mechanism by
which park visitors can enjoy the beauty and enormous natural diversity
that is an essential element of life in the San Francisco Bay area
while also participating in some of their favorite activities, be they
walking, hiking, geocaching, jogging, bicycling, horseback riding or
just absorbing the sights and sounds of the natural world around us. Mountain bikes and hikers on the Rocky Ridge Trail Hikers pushing a trail stroller

Visitor SafetyHikers on the Norred Trail Hikers and equestrian on the Fortini Trail Note that a trail bed of 4 feet does not mean that the trail tread, that portion of the trail that is normally walked or ridden on, need be a full 4 feet. Most trails will fill in with vegetation leaving a 1 to 2 foot tread but will still have room for passing. Trail surfaces also have to be relatively flat and free of tripping hazards and excessively long, steep grades must be avoided, even though some users may find them challenging. Trails built on contour with natural curves and undulations blend into the landscape without detracting from them and are much safer for all visitors. Many of our trails also have to act as access roads for emergency use to accommodate fire and medical vehicles. While these one-lane roads are not as attractive as smaller, more intimate trails, they are never-the-less necessary for park maintenance and safety. Equestrian on the Norred Trail Environmental ImpactMountain bike approaching the Stile Ranch Trail middle switchbacks Our regional parks are as much preserve as playground. An important part of the County Parks Department charter is to protect and preserve the natural environment and cultural history of Santa Clara County. Trails have to be designed and maintained to minimize damage to the environment while providing access to it. Of particular concern is erosion, both from rainfall and from visitor traffic. Trails are designed to shed water rather than concentrating it. This requires proper alignment, outsloping and drainage structures, all of which can breakdown over time and require periodic maintenance. Fall-line trails, which run straight down a hill are particularly problematic and are avoided at all costs as are excessively steep trail segments, even though they may be enjoyable for some park visitors. Some parks, Santa Teresa in particular, contain especially sensitive areas that are very fragile and easily damaged. It is particularly important that visitors remain on the trails in these areas, principally along the Stile Ranch and Rocky Ridge trails, as they have thin soils that can be easily damaged and take a long time to recover. Off-trail areas also provide important habitat for native plants and animals. Santa Teresa hosts a wonderful variety of plants, including several critically endangered species found in few other places. Numerous birds (including golden eagles), animals (including deer, bobcat, coyote and probably the occasional mountain lion) and reptiles are also endemic to the park and need room, apart from humans, to rest and reproduce.

junction.
All trails require periodic maintenance. Given the limited resources
available, trails must be designed to minimize maintenance while
holding up to heavy visitor use. Trails are aligned to avoid problem
situations such as slide prone areas, wetlands and unstable soils. When
maintenance is performed, it often has to be done with the long-term in
mind. Just keeping the trails free of bothersome plants such as poison
oak and thistle is a constant struggle. Brushing and tread maintenance
are often performed to last for at least three years. While this may
result in what looks like drastic changes to the trail, they are
usually short-lasting, and the trail will return to its normal, rustic
appearance in a year or so. Norred Trail at the Joice Trail junction, after the work was done. Ohlone Trail 6/16/08. The trail is overgrown and eroded.

Meeting all these requirements is difficult, especially since many of our park trails are old ranch, mine or fire roads that were not designed specifically for trail use and many of our older trails were built to standards that have now become outdated or inappropriate for an urbane interface area like Santa Clara County. With unlimited resources, it might be possible to develop special trails to cater to the particular needs of specific user communities: technical trails for advanced mountain bicyclists; steep trails for fans of advanced physical fitness; equestrian only trails to prevent conflicts between equestrians and other users; hiker-only single track; etc. But resources are not unlimited and currently the only viable solution is multi-users trails that can serve, but may not fully please, all park visitors. In spite of these limitations, our park trails can provide a rich, rewarding experience for all users as long as we are considerate of other users and respectful of the park’s natural resources.
