  • Section 4-6 Hydrology, Water Quality and Hazardous Materials
    Section 4-6 Hydrology, Water Quality and Hazardous Materials This section addresses potential impacts related to hydrology, water quality, and hazardous materials resulting from the implementation of the Proposed Project. Impacts on surface water and groundwater resources that may result from the Proposed Project are identified, and mitigation measures to avoid, minimize, and compensate for potentially significant impacts on surface water and groundwater resources are described. The potential impacts related to hazardous materials that may exist as a result of the prior farmstead and agricultural use on the Alamo site will also be described. The Proposed Project contains existing agricultural water supply lines. No additional water supply would be required as a result of Project implementation, therefore this issue is not discussed in this section. 4-6.1 STUDY METHODS Methods used to identify and evaluate hydrological resources in the study area consisted of a review of existing documentation. Hazardous materials discussion is based on the Phase I Environmental Site Assessment Update and Phase II investigation for the Alamo Creek Detention Basin (Dunn Environmental 2010). 4-6.1.1 Regional Setting Vacaville is located in the southern Sacramento Valley at the eastern foot of the Vaca Mountains on east- sloping alluvial fan surfaces that drain to the Sacramento River. The Sacramento River Basin encompasses approximately 26,500 square miles and is bounded by the Sierra Nevada to the east, the Coast Ranges to the west, the Cascade Range and Trinity Mountains to the north, and the Sacramento– San Joaquin Delta (Delta) to the south. Five creeks (Alamo, Ulatis, Gibson Canyon, Sweeney, and Horst Creek) pass through and provide drainage for the Vacaville area.

  • Upper San Joaquin River Basin Storage Investigation Draft
    Chapter 11 Geology and Soils This chapter describes the affected environment for geology and soils, as well as potential environmental consequences and associated mitigation measures, as they pertain to implementing the alternatives. This chapter presents information on the primary study area (area of project features, the Temperance Flat Reservoir Area, and Millerton Lake below RM 274). It also discusses the extended study area (San Joaquin River from Friant Dam to the Merced River, the San Joaquin River from the Merced River to the Delta, the Delta, and the CVP and SWP water service areas). Affected Environment This section describes the affected environment related to geology, geologic hazards, erosion and sedimentation, geomorphology, mineral resources, soils, and salts. Where appropriate, geology and soils characteristics are described in a regional context, including geologic provinces, physiographic regions, or other large-scale areas, with some area-specific geologic maps and descriptions of specific soil associations. Geology This section describes the geology of the primary and extended study areas. Primary Study Area A description of the surficial geologic units encountered in the primary study area is presented in Table 11-1.

E-mail: [email protected] ABSTRACT: Engineered flood bypasses, or simplified conveyance floodplains, are natural laboratories in which to observe floodplain development and therefore present an opportunity to assess delivery to and sedimentation within a specific class of floodplain. The effects of floods in the Sacramento River basin were investigated by analyzing hydrograph characteristics, estimating event-based sediment discharges and reach erosion/deposition through its bypass system and observing sedimentation patterns with field data. Sediment routing for a large, iconic flood suggests high rates of sedimentation in major bypasses, which is corroborated by data for one bypass area from sedimentation pads, floodplain cores and sediment removal reporting from a government agency.

  • Review of Background Information and Flood Control Alternatives for Easkoot Creek, Stinson Beach CA
    SENT VIA EMAIL Technical Memorandum DATE: July 17, 2009 To: Neal Conatser, Assistant Engineer, Marin County Department of Public Works From: Michael Love P.E., Principal Engineer, Michael Love & Associates [email protected] / ph: 707-476-8938 / fax: 707-476-8936 Subject: Review of Background Information and Flood Control Alternatives for Easkoot Creek, Stinson Beach CA. Project Background Easkoot Creek in Stinson Beach, California is a tributary to Bolinas Lagoon in western Marin County. The creek drains a watershed of approximately 1.59 square miles (FEMA, 1997) of steeply sloping hills that border the Pacific Ocean before flowing through the town of Stinson Beach and into Bolinas Lagoon. Due to a lack of channel capacity, the stream frequently overflows its banks between the Arenal Avenue and Calle de Arroyo crossings (Figure 1). Nearly half of this 2,000-foot channel reach is located within the National Park Service (NPS) Golden Gate National Recreation Area (GGNRA) and is adjacent to several parking lots. The current-day stream reach of Easkoot Creek downstream of the GGNRA parking lots crosses under a series of streets, collectively referred to as the “Calles”. The Calles from Calle del Pinos to Calle del Arroyo frequently experience flooding from Easkoot Creek, compounded by occasional flooding from wave overtopping to the west. Regular out-of-bank flooding also occurs upstream of the Calles within the GGNRA parking lots and in the area of the Parkside Restaurant. Currently, flooding within lower Easkoot Creek is exacerbated by sedimentation that reduces channel capacity. Sedimentation and the resulting decrease in channel capacity likely contributed to the out-of-bank flooding that occurred at the Park Entrance during a relatively small flow event on January 25, 2008.
