Center for Ecosystem Management and Restoration SONOMA COUNTY Petaluma River Watershed The Petaluma River watershed lies within portions of Marin and Sonoma Counties. The river flows in a northwesterly to southeasterly direction into San Pablo Bay. Petaluma River In a 1962 report, Skinner indicated that the Petaluma River was an historical migration route and habitat for steelhead (Skinner 1962). At that time, the creek was said to be “lightly used” as steelhead habitat (Skinner 1962). In July 1968, DFG surveyed portions of the Petaluma River accessible by automobile from the upstream limit of tidal influence to the headwaters. No O. mykiss were observed (Thomson and Michaels 1968d). Leidy electrofished upstream from the Corona Road crossing in July 1993. No salmonids were found (Leidy 2002). San Antonio Creek San Antonio Creek is a tributary of Petaluma River and drains an area of approximately 12 square miles. The channel is the border between Sonoma and Marin Counties. In a 1962 report, Skinner indicated that San Antonio Creek was an historical migration route for steelhead (Skinner 1962).

  • Appendix E: Regional Geophysical Data
    APPENDIX E: REGIONAL GEOPHYSICAL DATA GEOPHYSICAL REGIONS We used the USGS uaternary deposits data, together with current topo- graphic data from the National Elevation Dataset ⅓-arc second Digital Elevation Model, and rainfall isohyets from the Sonoma County Water Agency, to divide the Laguna into geophysical regions. A study of surficial geology, precipitation, and topography revealed eighteen distinct geophysical regions. Defining these has proven to be especially useful in explaining why we see patterns of vegetation and the consequent patterns of human development throughout the watershed. Plate shows the eighteen geophysical regions of the Laguna. Their boundaries are well defined through the natural expression of rainfall pat- terns, surficial geology, elevation, soil, and vegetation. The immediate imprint of the rainfall pattern on the land is to create a natural landscape of softwood and hardwood forests, grasslands and chap- arral. Together with other natural ingredients, such as geological deposits, topographical features and soil characteristics, distinct vegetation zones become recognizable. BENNETT VALLEY This region is situated in the eastern half of the watershed and is wholly encompassed by the Matanzas region. Matanzas Creek itself forms the region’s western backbone. The region is called out for its distinct topog- raphy, which is gently tipped towards the west. The region enveloping Bennett Valley from the south, east and west, is characterized by steeper hills with drainage towards this bowl-shaped valley. From southeast to northwest, the region’s major axis is about three miles long. The valley is 472 Enhancing and Caring for the Laguna almost one and a half miles wide at its southern end and tapers down to about three-fourths of a mile in width at its northern end.

  • 3.6 Geology and Soils
    3.6 GEOLOGY AND SOILS 3.6 GEOLOGY AND SOILS This section describes the geology of the project site and surrounding vicinity and analyzes issues such as potential exposure of people and future improvements to geologic hazards, alterations to terrain, and erosion. It also discusses the types of soil that have been identified on the site and their properties as they relate to the proposed project. In addition, potential geologic and seismic hazards such as earthquakes and landslides are discussed. Finally, mineral resources are discussed and analyzed. 3.6.1 SETTING LOCAL GEOLOGY AND TOPOGRAPHY The Specific Plan area lies within the geologic region of California referred to as the Coast Ranges geomorphic province. The Coast Ranges province lies between the Pacific Ocean and the Great Valley (Sacramento and San Joaquin valleys) provinces and stretches from the Oregon border to the Santa Ynez Mountains near Santa Barbara. Much of the Coast Ranges province is composed of marine sedimentary deposits and volcanic rocks that form northwest- trending mountain ridges and valleys, running subparallel to the San Andreas Fault Zone. The relatively thick marine sediments dip east beneath the alluvium of the Great Valley. The Coast Ranges can be further divided into the northern and southern ranges, which are separated by the San Francisco Bay. The San Francisco Bay lies within a broad depression created from an east–west expansion between the San Andreas and the Hayward fault systems. (Santa Rosa General Plan 2035 DEIR, 2009) The Northern Coast Ranges largely comprise the Franciscan Complex or Assemblage, which consists primarily of graywacke, shale, greenstone (altered volcanic rocks), basalt, chert (ancient silica-rich ocean deposits), and sandstone that originated as ancient sea floor sediments.

On the right side (about 1:00) is Mt Burdell across the Petaluma River Valley. This prominent mountain is composed of 11 Ma volcanics overlying an unnamed Miocene marine sandstone, which overlies Franciscan Complex. This assemblage is nearly identical to an assemblage to the 11Ma Quien Sabe Volcanics/Mid Miocene Lone Tree Formation/Franciscan Complex east of Hollister and has provided strong evidence for about 190 km of combined offset along faults in the East Bay such as the Hayward and Calaveras Faults.
