Earthquakes can also induce liquefaction, or the transformation of solid soil materials to those exhibiting fluid-like characteristics. Liquefaction primarily occurs in fine textured soils and its effects are most commonly observed in low-lying areas near water bodies. Upland soils that have large percentages of silt and substantial moisture, but are not saturated, can also liquefy. In general, the bay mud, dune sand, marine/marsh deposits, alluvium and colluvium found in the region are susceptible to liquefaction (Marin County 2005) which can result in landslides, broken utility lines, loss of soil bearing strength, ground fissures and building collapse. A soil‘s plasticity index (PI) is defined as the numerical difference between the liquid limit and plastic limit of the soil, typically expressed as a percentage, and for the scope of this Plan can be used to infer the liquefaction potential of an area. Soils that have a high PI value have a wide range of moisture content in which the soil performs as a plastic material. In general, an increase in PI decreases the soil‘s liquefaction potential, and soils with PI values of greater than 15 percent seem to be non-liquefiable. Most soils in the proposed project area have variably low to moderate PI levels, indicating that there exists potential in some soil units for liquefaction in an earthquake. The Blucher-Cole complex soils range between 10 and 25% based on soil texture and depth, with higher PI levels near the surface and lower levels as the soils are deeper; these are not as likely to liquefy.
The same is true with the Cronkite soils. However, the Barnabe soils found within the CronkiteBarnabe complex are highly liquefiable, with PI values ranging from only five to ten percent. The Humaquepts soils have a relatively low potential for liquefaction, ranging from 13-34% based on soil depth. The remaining soils (Tamalpais-Barnabe variant and Xerothents) are not rated (NRCS 2007). A precise geotechnical analysis would be required to identify the presence or absence of soil conditions conducive to liquefaction at each of the existing and proposed sites.
Under the No Action Alternative the areas identified as potential equestrian sites would remain in the current condition. Lower Redwood Creek is a prior flower farm now serving as a residential site. Many of the farm buildings and facilities are present. The Marincello site is an approximately 2-acre open space on Marincello Trail about 0.2 miles north of the Tennessee Valley Trailhead Parking lot.
Features common to all of the action alternatives are described below. Where action alternatives discuss new or modified facilities and services, the alternative would allow for the specified facility or service to be constructed as soon as a funding mechanism is identified, such as via business leases. NPS is not obligated to fund and develop the facilities or provide the services identified in these alternatives. Further, implementation of the Marin Equestrian Stables Plan alternatives must be compatible with the General Management Plan (GMP). Business Management Strategy. Table 2- 5 outlines the components of this strategy.
