Flood Insurance?
Safe, Clean Water and Natural Flood Protection Program The passage of the Safe, Clean Water and Natural Flood Protection Program in 2012 has made the community’s long term goals for protecting the future of the Santa Clara Valley possible, including: • Supplying safe, healthy water • Retrofitting dams and critical infrastructure for earthquakes • Reducing toxins, hazards and contaminants • Restoring wildlife habitat in our waterways • Providing natural flood protection Even though we are in a drought, flooding can happen. Santa Clara County has had several damaging floods over the years, Extreme dry conditions can harden the ground. Within the first few most notably in 1995 and 1997 along the Guadalupe River and 1998 days of heavy rain, the ground can deflect water into streams and along Coyote and San Francisquito creeks.

Field Trip to the Skyline Ridge Region in the Santa Cruz Mountains
Field Trip to the Skyline Ridge Region in the Santa Cruz Mountains Trip highlights: fault scarps, sag ponds, vegetation and bedrock contrasts, regional vistas, Quaternary gravels, Tertiary marine rocks, ancient submarine landslide deposits, volcanic rocks (Mindego Basalt), Indian mortar holes in sandstone This field trip guide includes a collection of stops that may be selected to plan a geology field trip. The field trip stops are along Highway 9 (Saratoga Road) and Highway 35 (Skyline Boulevard) between Castle Rock State Park and La Honda on Highway 84. Most stops are on lands maintained by the Midpeninsula Regional Open Space District. Outcrop and natural areas along the ridgeline crest of the Santa Cruz Mountains west of the San Andreas Fault are featured. Stops also include excursions to the fault itself in the Los Trancos and Monte Bello Open Space preserves, and at the Savannah- Chanelle Vineyards (built directly on the fault). The inclusion of all stops listed below might be possible only with an early start and plans for a long day in the field. Stop descriptions below include information about interesting geologic features in the vicinity, but they may require additional hiking to visit. Note that rattlesnakes can be encountered anywhere. Poison oak is prevalent, and ticks can be encountered any time of year, but mostly in the spring. The area is also mountain lion habitat. It is advisable to contact the Midpeninsula Open Space District before planning group visits to the preserves; their website is: http://www.openspace.org. Figure 7-1.

Creeks & Riparian Areas
Creeks & Riparian Areas early 17 miles of waterco urses flow through Los Altos Hills, transect four watersheds: Permanente, Adobe, Barron and MNatadero watersheds, and incl ude 12 named creeks: Adobe Creek Dry Creek Permanente Creek Magdalena Creek Barron Creek Hale Creek Robleda Creek Matadero Creek Deer Creek Loyola Creek Summerhill Creek Purissima Creek Creeks and their associated riparian corridors are important public assets that provide unique ecological, aesthetic, and recreational values to the community. The Los Altos Hills stream system contains some of the most intact and valuable riparian habitat in the San Francisco Bay region. —Los Altos Hills General Plan: Conservation Element, 305 (p 2) What Are Riparian Areas? Riparian areas are the lands along the banks of a natural course of fresh water, such as a river, stream, creek, drainage swale, spring, or seep. They are the transition zones between aquatic and terrestrial ecosystems. Different from surrounding lands because of the unique soil and vegetation characteristics associated with the presence of water, riparian areas support vegetation that is distinct from what grows in the adjacent aquatic zone on one side and the drier upland zone on the other. 1 Why Are Riparian Areas Important? Riparian areas provide valuable ecosystem services, the processes by which the environment produces vital resources such as clean water, timber, habitat for fisheries, and pollination of native and agricultural plants. Within Los Altos Hills, riparian areas moderate downstream flooding, limit stream bank erosion, improve local water quality, recharge groundwater, and provide habitat and important migratory corridors for wildlife. Although they comprise only a small fraction of the land area, riparian areas are among the most important, diverse, and productive ecosystems in the region. -
