  • Physical Setting
    Physical Setting Dunne and Leopold (1978) define a watershed as an area of land that drains water, sediment, and dissolved materials to a common outlet at some point along a stream channel. The Santa Ana River (SAR) Watershed, depicted in Figure 3-1, drains a 2,650 square-mile area. The watershed is home to over 6 million people and includes the major population centers of parts of Orange, Riverside, and San Bernardino Counties, as well as a sliver of Los Angeles County. The Santa Ana River flows over 100 miles and drains the largest coastal stream system in Southern California. It discharges into the Pacific Ocean at the City of Huntington Beach. The total length of the SAR and its major tributaries is about 700 miles. 1 | W a t e r s h e d S e t t i n g Figure 3-1 Santa Ana Integrated Regional Water Management Region The watershed boundaries nearly match the boundaries of the Santa Ana Regional Water Quality Control Board, an organization with whom the Santa Ana Watershed Project Authority (SAWPA) has worked closely with for many years. In addition, its boundaries match the Integrated Regional Water Management (IRWM) region and the recognized Santa Ana Funding Area, as defined by the Proposition 84 IRWM program. Although there are many sub-watershed planning efforts, One Water One Watershed 2.0 (OWOW) attempts to bring all these efforts, as well as all different jurisdictions in the watershed, into a single watershed-wide vision. Over the years, SAWPA has participated in the development of sub-regional IRWM plans, with the understanding that such plans would be complementary to OWOW.

    Old, Grand Prix, and Padua Fires (October, 2003) Burn Impacts to Water Systems and Resources Santa Ana River Watershed Area San Bernardino National Forest, California Prepared for: Burn Area Emergency Response (BAER) Team U.S. National Forest Service Santa Ana Watershed Project Authority 11615 Sterling Avenue Riverside, CA 92503 (909) 354-4224 www.sawpa.org November 10, 2003 (Revised December 5, 2003) SUMMARY The Santa Ana Watershed supplies most of the drinking water for over 5 million of the Watershed’s residents. Rainfall in and around the San Bernardino, San Gorgonio and San Jacinto Mountains’ forest areas, provides surface water flows and groundwater recharge throughout the region via the Santa Ana River and its tributaries. Recent fires in these areas were large and difficult to contain and the aftermath of these fire events have resulted in extraordinary impacts on the forest and the Watershed. The recent Grand Prix, Old and Padua Fires burned over 120,000 acres (more than 185 square miles) of wild land habitat in the Santa Ana Watershed, primarily within the San Bernardino National Forest. These fires will have significant impacts on the Santa Ana River and its associated water quality for an extended period and will impact areas far from the burned sites. It is estimated that the fires’ effects will impact an additional 430 square miles of the Watershed. In sum, Burned Mountaintop the recent fires will impact one-quarter of the Watershed and without intervention most of the associated costs will be borne by local government. The purpose of this summary is to document the likely impacts to water supply, quality, habitat Issues Summary and flood control throughout the Watershed resulting from the Grand Prix, Old and Padua Fires.

  • Mountain Park Specific Plan
    Mountain Park Specific Plan I. INTRODUCTION A. Project Location The proposed Mountain Park Specific Plan project site is located generally in Gypsum Canyon, south of the Riverside (SR-91) Freeway, in the City of Anaheim and its sphere of influence, Orange County, California. The majority of the Mountain Park project site is in the jurisdiction of the City of Anaheim; however, the southern- and eastern-most portions of the project site are in unincorporated County of Orange in the City of Anaheim’s sphere-of-influence. SR-91 is immediately north of the project site, and the Eastern Transportation Corridor (SR-241) bisects the site into eastern and western segments. A regional location map and aerial perspective of the project site are depicted on Exhibits 1 (Location Map) and 2 (Aerial Perspective of Project Area), respectively. B. Existing Site Characteristics The Mountain Park Specific Plan encompasses approximately 3,001 acres. The project site is currently undeveloped with the exception of a 300-acre sand and gravel mining operation located in the northeastern portion of Gypsum Canyon which will be vacated in June 2005. Access to the project site is currently provided from Gypsum Canyon Road via Santa Ana Canyon Road and the Gypsum Canyon Road interchange with SR-91. The project site is gated and public access is not allowed. There are a number of unimproved dirt roads that traverse the site that were used for previous on-site operations and emergency access. The project site is topographically complex with several steep canyons and intervening ridges. Elevations within the project site range from 340 feet above mean sea level (amsl) in the northern portion of the project area to 2,200 feet amsl in the southern portion of the site.

  • A 100 Year History of Wildfires Near Chino Hills State Park 1 Introduction Fires Are a Natural Part of the Ecosystem
    A 100 Year History of Wildfires Near Chino Hills State Park © August 2012. All Rights Reserved. ABSTRACT After witnessing the devastation of the Freeway Complex Fire, the regional conservation non-profit Hills For Everyone undertook a study of fires in the region. Though fires are a natural part of the ecosystem, there is nothing natural about the size and frequency of the fires destroying our wildlands year after year. Data, mainly from fire agencies, the California Department of Parks and Recreation, and newspapers, have provided details on fire perimeters, points of origin, and fire causes. This paper is the culmination of research that documents a near 100-year fire history (1914-2011) in and around Chino Hills State Park. This paper articulates the problem months, weather conditions, and “hot spots” of fire ignition. Recommendations are included for residents, jurisdictions, and fire, transportation, and natural resource agencies to implement that would reduce the number of fires to a more natural fire regime. We will continue to work with fire and natural resource agencies to bring the necessary resources to this area. A 100 Year History of Wildfires Near Chino Hills State Park 1 INTRODUCTION Fires are a natural part of the ecosystem. Many factors influence the natural fire regime: weather conditions, vegetation (fuel) types, vegetation moisture, and plant distribution, etc. The natural fire regime, however, has been drastically altered by humans who have caused many more fires than would have occurred naturally. “New” factors influencing this increased fire regime include the introduction and proliferation of flammable non-native vegetation (e.g., palm trees, pampas grass, Arundo donax, exotic annual grasslands, etc.), increased Wildland-Urban Interface (WUI), and roadways to name a few.

  • Cultural Resources
    Santa Ana River Parkway Extension Project Section 5.0 5.4 CULTURAL RESOURCES This section describes the existing paleontological, archaeological, and historic resources known to exist in the project area; potential environmental impacts; recommended mitigation measures to reduce or avoid impacts to identified paleontological, archaeological, and historic resources; and the significance determination after the incorporation of mitigation. The analysis in this section was summarized from the Santa Ana River Parkway Project – Cultural Resources Assessment (AECOM 2014b). This report is included as Appendix F of this Draft EIR. 5.4.1 EXISTING CONDITIONS The project area is located on Black Star Canyon and Prado Dam United States Geological Survey (USGS) 7.5-minute quadrangle maps (USGS 2012a and USGS 2012b, respectively) within the City of Yorba Linda and unincorporated Orange County, California. The project site is located on unsectioned land of the former Yorba family land grants of Canon de Santa Ana, Santiago de Santa Ana, and Lomas de Santiago. 5.4.1.1 Geological Setting The proposed project is located in the Santa Ana Canyon or Santa Ana Narrows. The canyon and riverbed were created by tectonic activity of the Elsinore-Whittier Fault, at the north end of the Peninsular Range. The Santa Ana River (SAR) marks the dividing line between the Santa Ana Mountains and the Chino Hills. The Santa Ana Narrows were formed as a result of the faulting that formed the Chino Hills and Santa Ana Mountains. The topography both channels the river water and forces it to the surface. The faulting has also uplifted and exposed beds of sedimentary rock dating from the Cretaceous to the Neogene Periods.
