    SOUTHEAST GREENWAY GENERAL PLAN AMENDMENT AND REZONING DRAFT EIR CITY OF SANTA ROSA HYDROLOGY AND WATER QUALITY 4.8 HYDROLOGY AND WATER QUALITY This chapter includes an evaluation of the potential environmental consequences associated with the adoption and implementation of the proposed project that are related to hydrology and water quality. Additionally, this chapter describes the environmental setting, including regulatory framework and existing conditions, and identifies mitigation measures, if required, that would avoid or reduce significant impacts. 4.8.1 ENVIRONMENTAL SETTING 4.8.1.1 REGULATORY FRAMEWORK Federal Regulations Clean Water Act The Clean Water Act (CWA) of 1977, as administered by the United States Environmental Protection Agency (USEPA), seeks to restore and maintain the chemical, physical, and biological integrity of the nation’s waters. The CWA employs a variety of regulatory and non-regulatory tools to reduce direct pollutant discharges into waterways, finance municipal wastewater treatment facilities, and manage polluted runoff. The CWA authorizes the USEPA to implement water-quality regulations. The National Pollutant Discharge Elimination System (NPDES) permit program under Section 402(p) of the CWA controls water pollution by regulating stormwater discharges into the waters of the United States. California has an approved State NPDES program. The USEPA has delegated authority for water permitting to the State Water Resources Control Board (SWRCB) and the North Coast Regional Water Quality Control Board (RWQCB) (Region 1). Section 303(d) of the CWA requires that each state identify water bodies or segments of water bodies that are “impaired” (i.e., not meeting one or more of the water-quality standards established by the state).

  • Dear Friends, Sonoma County Is Celebrating the Winter and Spring Rains Which Have Left Our Rivers and Creeks with Plenty of Clea
    This picture of Mark West creek was taken in April by our intern, Nick Bel. Dear Friends, Sonoma County is celebrating the winter and spring rains which have left our rivers and creeks with plenty of clear clean water going into summer. Many of CCWI’s water monitors have noted that local rivers and creeks have more water and are more beautiful than they have been in the past several years. This is a very promising start to the summer season, but we should not let our guard down just yet. Several years of drought have left us with a shortage of water in many reservoirs so we must still be conscious of how we use and protect this precious resource. CCWI has a new program Director! Art Hasson joined the Community Clean Water Institute in 2008 as an intern and volunteer water monitor. Art has a business degree from the State University of New York, which he has put to good use as our new program director. He has updated our water quality database engaged in field work, performed flow studies and bacterial analysis for the past two years. Art is focused on protecting our public health through the preservation of our waterways. CCWI would like to thank outgoing program director Terrance Fleming for his hard work and valuable contributions to protect water resources. We wish him the very best in his future endeavors. CCWI would like to thank our donors for their support in building our online database interactive database. It contains nine years of data that CCWI volunteer water monitors have collected on local creeks and streams in and around Sonoma County.

  • 1 CALIFORNIA DEPARTMENT of FISH and GAME STREAM INVENTORY REPORT Big Austin Creek Report Revised April 14, 2006 Report Complete
    CALIFORNIA DEPARTMENT OF FISH AND GAME STREAM INVENTORY REPORT Big Austin Creek Report Revised April 14, 2006 Report Completed 2000 Assessment Completed 1995 INTRODUCTION Stream inventories were conducted during the summers of 1995 and 1996 on Big Austin Creek. The inventories were conducted in two parts: habitat inventory and biological inventory. The objective of the habitat inventory was to document the amount and condition of available habitat to fish, and other aquatic species with an emphasis on anadromous salmonids in Big Austin Creek. The objective of the biological inventory was to document the salmonid and other aquatic species present and their distribution. The objective of this report is to document the current habitat conditions, and recommend options for the potential enhancement of habitat for Chinook salmon, coho salmon and steelhead trout. Recommendations for habitat improvement activities are based upon target habitat values suitable for salmonids in California's north coast streams. WATERSHED OVERVIEW Big Austin Creek is a tributary of the Russian River, located in Sonoma County, California (see Big Austin Creek map, page 2). The legal description at the confluence with the Russian River is T7N, R11W. Its location is 38°27'58" N. latitude and 123°2'57" W. longitude. Year round vehicle access exists from Austin Creek Road via Highway 116 near Cazadero. The upper road was only accessible through private locked gates. Big Austin Creek and its tributaries drain a basin of approximately 68.7 square miles. Big Austin Creek is a fourth order stream and has approximately 13 miles of blue line stream, according to the USGS Guerneville, Duncans Mills, Fort Ross, and Cazadero 7.5 minute quadrangles.

  • Special Information for Persons with Water Service from the City Of
    Special Information for Persons with Water Service from the City of Sebastopol regarding the Russian River Tributaries Water Conservation and Informational Order Emergency Regulation. This information is for our customers with City water service who have received correspondence from the State Water Resources Control Board regarding these emergency regulations. The City of Sebastopol’s water is sourced from wells which are not within the watershed boundaries of the four Russian River tributaries (Dutch Bill Creek, Green Valley Creek, Mark West Creek and Mill Creek) that are part of the Russian River Tributaries Emergency Regulation (California Code of Regulations, Title 23, Section 876). The Russian River Tributaries Emergency Regulation was submitted to the Office of Administrative Law on June 24, 2015 and was anticipated to go into effect on or around July 4, 2015. If all of your water is supplied by the City of Sebastopol, meaning you have no groundwater wells or surface water diversions and you do not receive water from any other sources, your responsibility under the Emergency Regulation is limited to the informational order provisions of the emergency regulation. If you receive an informational order from the State Water Board and you do not have a groundwater well or surface diversion, you would be required to provide minimal information indicating that your sole source of water is provided by the City of Sebastopol. Additional information on the Russian River Tributaries Emergency Regulation is available online at http://www.waterboards.ca.gov/waterrights/water_issues/programs/drought/ water_action_russianriver.shtml If you have questions regarding this information please contact the State Water Resources Control Board through the Russian River Tributaries Emergency Regulation Phone Number at (916) 322-8422 or by e-mail at [email protected] .

  • Chapter 7: Sustaining Our Water Resources
    SUSTAINING OUR WATER RESOURCES Watersheds are nested drainages, incorporating the entire land surface that collects water flowing to a geographic point. Different maps and planning documents refer to the Laguna channel and the Laguna watershed in dif- ferent ways, sometimes splitting off the Santa Rosa and Mark West Creeks as separate drainages. Within this plan, we define the Laguna watershed as the area that incorporates all these sub-basins, and when this definition needs to be underscored the phrase “greater Laguna watershed” is applied. This watershed definition is more ecologically appropriate, reflecting the biological and physical properties of the system. However, for regulatory purposes, the Laguna, Santa Rosa Creek and Mark West Creeks are split into separate drainages, as discussed below. Water quality concerns in the Laguna cannot be easily separated from the issues related to the Laguna’s hydrology and water dynamics. Restoring the Laguna’s water resources will require integrated research, planning and collaboration. HYDROLOGY The Laguna watershed has a complex and diverse hydrology—cool-water high-gradient creeks in the upper watershed flow down the hillsides to High gradient creeks, vernal pools, slow moving the broad, flat, vernal pool-dotted Santa Rosa Plain, meeting the warm, channel slow-moving Laguna main channel, that flows northward to join the Rus- sian River. During very large storms, the Russian River backs up into the Laguna’s low-gradient basin near Windsor and Mark West Creeks: this alleviates flooding in the lower Russian River valley, and strongly affects the Laguna ecosystem. In part because of these back flows, and in part Backflow, sediment retention, disconnected because of localized topographic constrictions, the Laguna does not have ponds scouring floods, and retains much sediment within its channels and flood- plains.
