CEQA Process On May 11, 2011, the County of San Mateo (the Lead Agency) released for public review a Draft Environmental Impact Report (Draft EIR or DEIR) on the proposed Pilarcitos Quarry Expansion Project (Project). A 45-day public review and comment period on the Draft EIR began on May 11, 2011, and closed on June 24, 2011. The County also held a public hearing to receive oral public comment on the Draft EIR at the San Mateo County Planning Commission meeting on June 8, 2011, at the Board of Supervisors Chambers in Redwood City. The Draft EIR for the proposed Pilarcitos Quarry Expansion Project, together with this Document, constitute the Final EIR for the proposed Project. The Final EIR is an informational document prepared by the Lead Agency that must be considered by decision-makers before approving the proposed Project (CEQA Guidelines, Section 15090). California Environmental Quality Act (CEQA) Guidelines (Section 15132) specify the following: “The Final EIR shall consist of: (a) The Draft EIR or a revision of that draft. (b) Comments and recommendations received on the Draft EIR either verbatim or in a summary. (c) A list of persons, organizations, and public agencies commenting on the Draft EIR. (d) The responses of the Lead Agency to significant environmental points raised in review and consultation process. (e) Any other information added by the Lead Agency.” This document has been prepared pursuant to CEQA and in conformance with the CEQA Guidelines. This document incorporates comments from public agencies and the general public, and contains appropriate responses by the Lead Agency to those comments. It also provides relevant new information that has come to light since publication of the Draft EIR, and revisions to the Draft EIR prompted by comments and by new information. Pilarcitos Quarry Expansion I-1 ESA / 205280 Final Environmental Impact Report December 2011 I. Introduction B. Method of Organization This Final EIR for the proposed Pilarcitos Quarry Expansion Project contains revisions to and completes the Draft EIR published in May, 2011. The document is organized as follows: Chapter I describes the CEQA process and the organization of this Final EIR. Chapter II contains new information that has come to light since publication of the Draft EIR. Chapter III contains a list of all persons and organizations that submitted written comments and those who provided oral comments at the Planning Commission Public Hearing on the Draft EIR during the public review period. Chapter IV contains copies of the comment letters and public hearing minutes, and the responses to those comments. Within each letter and public hearing minutes, individual comments are labeled with a number in the margin. Immediately following the comment letter are responses to each of the numbered comments. Chapter V contains revisions to the text of the Draft EIR. Some changes were made by the County; others were made in response to comments received on the Draft EIR. Chapter VI contains the Mitigation Monitoring and Reporting Program, which identifies the responsible parties and lays out the timeline for implementation, monitoring, and reporting of the mitigation measures specified in the EIR. Pilarcitos Quarry Expansion I-2 ESA / 205280 Final Environmental Impact Report December 2011 CHAPTER II New Information This Chapter provides new information regarding the Pilarcitos Quarry that has come to light since publication of the Draft EIR. A. Area H Expansion The environmental review of a previous version of the Pilarcitos Quarry Expansion Project commenced in 2005. At that time, West Coast Aggregates (the applicant) was seeking approval of a long-term master plan for future mining and reclamation of the Pilarcitos Quarry, under which approximately 256 acres of the 593-acre property (consisting of Expansion Areas A through J) would be disturbed. Since the quarry was reaching the limits of the area that could be mined under its then-current Mining and Reclamation Plan, however, the applicant simultaneously sought approval of the initial expansion area (Area H) encompassing 7.36 acres (see Figure III-5 in Chapter III, Project Description, in the Draft EIR), to enable the quarry to continue mining pending completion of the environmental review and consideration of approval of the larger Project. Environmental effects of the Area H expansion were analyzed in an Initial Study, prepared by County staff pursuant to CEQA Guidelines §15063, and completed in 2006. As the Initial Study identified no significant adverse environmental impacts for the Area H expansion project that could not be mitigated, and the applicant agreed to all identified mitigation measures, County staff recommended adoption of a Mitigated Negative Declaration, pursuant to CEQA Guidelines §15070. This recommendation was considered by the San Mateo County Planning Commission on May 10, 2006, but continued. In July, 2007, the County circulated a revised Initial Study and Draft Mitigated Negative Declaration that addressed issues raised in consultation and correspondence with the State Office of Mine Reclamation, the California Coastal Commission, the U.S. Fish and Wildlife Service, and the California Department of Fish and Game. The Mitigated Negative Declaration was adopted and the Area H expansion was approved by the Planning Commission following a public hearing at their September 26, 2007 meeting. A private party then appealed the approval to the Board of Supervisors, who, at their December 18, 2007 meeting, denied the appeal and upheld the Planning Commission approval. Following the denial, the approval of the Area H expansion was appealed to the California Coastal Commission. In August, 2009, while the appeal of the Area H expansion was pending before the Coastal Commission, the applicant submitted a revised Mining and Reclamation Plan (“Pilarcitos Quarry Pilarcitos Quarry Expansion II-1 ESA / 205280 Final Environmental Impact Report December 2011 II. New Information Master Expansion and Water Resource Project Mining and Reclamation Plan”), which covered mining on approximately 117 acres within the quarry property, including Expansion Areas H and J, a combined A+B area, associated reclamation, development of a large water storage feature within Areas A+B, and placement of a conservation easement over an additional 210 acres within the property.

  • Biological Opinion for the Lower Crystal Springs Dam Stilling Basin Connecting Channel Project in San Mateo County, California (Corps File No
    March 21, 2019 Refer to NMFS No: WCRO-2016-00003 Katerina Galacatos, Ph.D. Acting Regulatory Branch Chief Department of the Army San Francisco District, Corps of Engineers 450 Golden Gate Avenue, 4th Floor, Suite 0134 San Francisco, California 94102-3406 Re: Endangered Species Act Section 7(a)(2) Biological Opinion for the Lower Crystal Springs Dam Stilling Basin Connecting Channel Project in San Mateo County, California (Corps File No. 2006-30317S) Dear Dr. Galacatos: Thank you for your letter of July 13, 2016, requesting initiation of consultation with NOAA’s National Marine Fisheries Service (NMFS) pursuant to section 7 of the Endangered Species Act of 1973 (ESA) (16 U.S.C. 1531 et seq.) for the proposed Lower Crystal Springs Dam Stilling Basin Connecting Channel Project in the County of San Mateo, California (Project). The Corps of Engineers (Corps) proposes to provide authorization pursuant to Section 404 of the Clean Water Act of 1972, as amended (33 U.S.C. § 1344 et seq.), to the San Francisco Public Utilities Commission to construct the Project. The enclosed biological opinion is based on our review of the proposed Project and describes NMFS’ analysis of the effects on threatened Central California Coast (CCC) steelhead (Oncorhynchus mykiss) in accordance with section 7 of the ESA. In the enclosed biological opinion, NMFS concludes the Project is not likely to jeopardize the continued existence of threatened CCC steelhead. However, NMFS anticipates take of CCC steelhead will occur as a result of dewatering work areas during project construction. An incidental take statement with non-discretionary terms and conditions is included with the enclosed biological opinion.

  • San Mateo County
    Steelhead/rainbow trout resources of San Mateo County San Pedro San Pedro Creek flows northwesterly, entering the Pacific Ocean at Pacifica State Beach. It drains a watershed about eight square miles in area. The upper portions of the drainage contain springs (feeding the south and middle forks) that produce perennial flow in the creek. Documents with information regarding steelhead in the San Pedro Creek watershed may refer to the North Fork San Pedro Creek and the Sanchez Fork. For purposes of this report, these tributaries are considered as part of the mainstem. A 1912 letter regarding San Mateo County streams indicates that San Pedro Creek was stocked. A fishway also is noted on the creek (Smith 1912). Titus et al. (in prep.) note DFG records of steelhead spawning in the creek in 1941. In 1968, DFG staff estimated that the San Pedro Creek steelhead run consisted of 100 individuals (Wood 1968). A 1973 stream survey report notes, “Spawning habitat is a limiting factor for steelhead” (DFG 1973a, p. 2). The report called the steelhead resources of San Pedro Creek “viable and important” but cited passage at culverts, summer water diversion, and urbanization effects on the stream channel and watershed hydrology as placing “the long-term survival of the steelhead resource in question”(DFG 1973a, p. 5). The lower portions of San Pedro Creek were surveyed during the spring and summer of 1989. Three O. mykiss year classes were observed during the study throughout the lower creek. Researchers noticed “a marked exodus from the lower creek during the late summer” of yearling and age 2+ individuals, many of which showed “typical smolt characteristics” (Sullivan 1990).

Our Sponsors Clothing Giving Events Local Routes FAQ Contact Our favorite cycling routes near Stanford Local Routes (Road) Shorter Flat Options The mini-loop: This is the route you want to take on a day when your legs are screaming and your body is aching and anything more than half hour will kill you. Take Old Page Mill to Arastradero and right on Arastradero to Alpine and right on Alpine to Campus. Ideal addition to get your extra half hour in on your base training days when you miscalculated a longer ride. [Aerial Photo] The Loop: Ideal option for a flat route with no stop lights on a recovery day. The standard route normally starts o by heading up Alpine to Portola and taking Portola to Sand Hill. The reverse direction is popular with the tailwind speedsters dashing along the downward slant of Alpine Rd. The benchmark 15 mile route can be enhanced by further additions like Arastradero; going to the gate at the end of Alpine; adding the "maze" to it in Woodside. The "maze" is short for: taking Tripp on 84E to Kings, R on Kings, L on Manuella, L on Albion and R on Olive Hill to Canada (or the reverse direction). Time: 45 mins to 1 hr + (depending on additions) [Aerial Photo (B/W)] Foothill: Reserved for days when all you want to do is recover as frequent stop lights make any steady eort quite impossible. The turnaround points for 45 mins (Grant), 1 hr (Homestead), 1:15 (if the route parallel to foothill is taken on way back), 1:30 (Stevens Creek Blvd).

  • 5. Coastal Access and Recreation
    5. Coastal Access and Recreation Maximizing coastal access and recreational opportunities is a primary objective of the California Coastal Act. This chapter of the Local Coastal Land Use Plan (LUP) documents existing coastal access conditions, and describes improvements needed to enhance access to the coast for people arriving by all modes of transportation. Recreational open space is a defining feature and an extraordinary resource for Half Moon Bay, and another high priority under the Coastal Act. This chapter also documents existing public recreational facilities, evaluates local and visitor demand for recreational facilities, identifies priority improvements, and evaluates the recreational needs of the community. Coastal access and recreation are overlapping objectives. Providing coastal access is essential to promoting coastal recreation. Coastal access points offering support facilities such as transit and parking enable visitors to participate in coastal recreation activities. However, conflicts, such as recreation events that block beach access, must be identified and addressed in policies. Furthermore, the very nature of coastal access and recreational facilities is that they are often in direct contact with sensitive coastal habitat areas such as beaches and coastal bluffs. In that coastal resource protection is another primary objective of the California Coastal Act, the potential impacts of coastal access and recreation on habitat and other resources must be understood and policies should guide environmentally sustainable coastal access and recreational facilities and programs. Land Use Plan Framework Upon its admission into the United States in 1850, the State of California became the owner of all tidelands, submerged lands, and all lands lying beneath inland navigable waters.
