The District's purpose is to acquire, permanently protect, and restore lands forming a regional open space greenbelt. The preserves are generally Midpeninsula Regional Open Space District Page 3 of 16 RFQ for Design-Build Services | Mindego Ranch Ponds Enhancement Project kept in a natural condition to protect their ecological integrity and habitat, and are developed with only those amenities needed for low-intensity recreation, such as signed trails for hiking, dog walking, bicycling, and equestrian use, restrooms, gravel parking areas, and an occasional bench or picnic table. The preserves are open to the public year-round and contain many diverse ecosystems, including redwood, oak, and fir forests; chaparral-covered hillsides; riparian corridors; grasslands; and shore frontage along San Francisco Bay. 3.0 PROJECT SCOPE AND OBJECTIVES 3.1 Project Objectives. The Ponds are located in the 3,137-acre Russian Ridge Open Space Preserve in San Mateo County, California. The Ponds are habitat for three special status species: the San Francisco garter snake, the California red-legged frog, and the western pond turtle. The Project objectives include a low cost, feasible design for Pond enhancements to improve the habitat for these sensitive species, with emphasis on habitat needs for the San Francisco garter snake and its prey base (California red-legged frog and other amphibians), and to provide for cost-efficient maintenance and repair of the improvements. The District’s primary objective in using design-build delivery for this Project is to select the team with the best combined design and construction experience and expertise to work collaboratively with District personnel to address the unique challenges presented by this Project. 3.2 Project Background. A San Francisco Garter Snake Habitat Management Plan was completed in September 2012 (2012 Plan) (Attachment 1) that identified site-specific management strategies for enhancing SFGS habitat within the preserve. This project will focus on design plans and associated geotechnical, topographical, and hydrological, investigations, and construction and implementation of the following recommendations, listed by water body, for two of the three ponds listed in the Management Plan. This work is permitted under the District’s existing 10(a)1(A) Recovery Permit for San Francisco garter snake issued by the US Fish and Wildlife Service. Other project permits anticipated for the project include: Regional Water Quality Control Board Section 401 Waste Discharge Requirements, US Army Corps of Engineers Section 404 Nationwide permit, California Department of Fish and Wildlife Lake and Streambed Alteration Agreement, and San Mateo County grading permit and/or grading exemption through the San Mateo County Resource Conservation District (RCD). The RCD has expressed a willingness to obtain the appropriate grading exemption through San Mateo County in support of this project. The DBE, using information generated during project design will complete all permitting applications with these agencies, however permits will be issued in the name of the District. Midpeninsula Regional Open Space District Page 4 of 16 RFQ for Design-Build Services | Mindego Ranch Ponds Enhancement Project Upper Spring (referred to as Upper Lake in 2012 Plan): Perform limited topographic surveys and bathymetric surveys of the water body to determine the amount of sediment removal required for intended enhancement (refer to design parameters (Attachment 2), i.e. minimum of 3-foot depth, ponding through August etc. or see below) Perform geotechnical investigations of outlet as appropriate, which may include (but is not limited to): the cement lined outlet structure embedded within the earthen berm that forms Upper Spring, the degraded downstream outlet, and the main berm. The District reserves the right to have a third party review all geotechnical survey results There is access to the berm but it is possible that the geotechnical investigation will require removal of up to 125 linear feet of vegetation to gain access, hand augurs may be used as an alternative if appropriate Provide design to achieve the habitat enhancement recommendations from the 2012 Plan to meet the following objectives: 1) removal of 80-90% of emergent vegetation while maintaining 20-50% of perimeter vegetation. 2) removal of an estimated 75-125 cubic yards of sediment within the basin so that 50% of the water body is at least 3 feet deep with a gradual 20-30% slope allowing for transition between shallow and deep water on at least one side of the pond Once a preliminary 35% design is produced, the storage of the pond shall be reviewed by the District’s water resources specialist to ensure compliance with existing water rights Provide design to repair and/or replace eroded outlet once the water body has been cleaned. The existing outlet should be stabilized, and/or replaced to support a ponding capacity that is conducive to frog rearing and development (generally 4-6 feet deep in ponds that are not spring fed. Since Upper Springs is spring fed the depth may be reduced to a minimum of 3 feet if this will allow for a long enough ponding duration to support CRLF development) Design should accommodate a 100-year flow from outlet and/or spillway without failing or causing erosion. Preferably this would include both a primary and secondary outlet but a single outlet system could be acceptable if justified Provide detailed geotechnical information and associated plans and specifications as needed to fulfill San Mateo County and other permitting needs The District reserves the right to hire a third party to review any and all geotechnical, topographical, and hydrological survey results Midpeninsula Regional Open Space District Page 5 of 16 RFQ for Design-Build Services | Mindego Ranch Ponds Enhancement Project Knuedler Lake: Perform limited topographic surveys and bathymetric surveys of the pond to determine the amount of sediment removal required for intended enhancement Perform geotechnical investigations of outlet as appropriate, which may include (but is not limited to): the downstream outlet, and the main berm Assess the erosion potential of the incised creek channel 75 feet from the high water line along the pond outlet (below the pond). Provide design to eliminate future downstream erosion below the pond. Elements can include adequate sizing of spillway to prevent further head cutting, more extreme measures such installing an energy dissipater to stabilize the channel (if warranted), or other approaches as appropriate Provide design to achieve the habitat enhancement recommendations from the 2012 San Francisco Garter Snake Habitat Management Plan (to include entire lake if access is granted) to meet the following objectives: 1) removal of 80-90% of vegetation from the pond basin (property line with City and County of San Francisco Juvenile Probation Department bisects the pond) 2) Removal of an estimated 600 (+/- 200) cubic yards of sediment from the pond to deepen the pond to a maximum depth of 4-6 feet with a gradual 20-30% slope allowing for transition between shallow and deep water. Design should accommodate a 100-year flow without failing or causing erosion from outlet and/or spillway.

  • Considerations for Rezoning on Lakes
    STATE OF MAINE DEPARTMENT OF AGRICULTURE, CONSERVATION & FORESTRY LAND USE PLANNING COMMISSION 22 STATE HOUSE STATION WALTER E. WHITCOMB PAUL R. LEPAGE AUGUSTA, MAINE 04333-0022 COMMISSIONER GOVERNOR NICHOLAS D. LIVESAY EXECUTIVE DIRECTOR Memorandum To: LUPC Commissioners From: Samantha Horn, Planning Manager Ben Godsoe, Senior Planner Date: October 5, 2018 Re: Considerations for Rezoning Near Lakes, Staff Analysis Lake resources are important to Maine’s character, environment and economy. Healthy lakes are a strong draw for local residents and visitors alike, and play a critical role in sustaining fish and wildlife populations. When the Commission considers the location of future subdivisions, it is important to be deliberate about which lakes may be near new zones for subdivisions. The May 2018 draft of rule revisions for adjacency included a proposal that any new zones for waterfront subdivision should be either 1) on a lake or pond that is within a certain distance of services (i.e., within primary or secondary locations); or 2) on a lake or pond that is already developed. Outside of primary or secondary locations, lakes under the proposed revisions that could be eligible for rezoning include management class 3, 4, and 5 lakes, as well as certain class 7 lakes. During the public hearing on the draft rule revisions, commenters raised concerns that there was not sufficient information available to tell which or how many class 7 lakes qualify as having sufficient development to make them potentially be eligible for rezoning. Without this information, commenters raised concerns that a large number of lakes could possibly be “open for development.” Commenters requested more information on which class 7 lakes could be affected by the proposal.

  • Sources of Excess Phosphate Leading to Cyanobacteria
    SOURCES OF EXCESS PHOSPHATE LEADING TO CYANOBACTERIA BLOOMS AT LAKE TEMESCAL, OAKLAND, CA. A University Thesis Presented to the Faculty of California State University, East Bay In Partial Fulfillment of the Requirements for the Degree Master of Science in Geology By Faithe Lovelace March, 2017 Acknowledgements I would like to thank Dr. Jean Moran for the countless hours she put into this project, without your insight this project would not be possible. Thank you, Dr. Michael Massey, for your help and data. Thank you, Pamela, Beitz and all East Bay Regional Park District for presenting the project and the continuous support, suggestions, and funding for the project. Thank you, Glenn, Carr for your help in the field and all the support your provided. I would like also like to thank my parents Michael and Mary Catherine for their unwavering belief and support. ii Abstract Lake Temescal is a dammed sag pond formed as a result of long-term creep along the Hayward Fault. It is a popular swimming, hiking, and fishing spot within the East Bay Regional Parks District (EBRPD). Over the past decade, the lake has experienced numerous cyanobacteria (commonly known as “blue green algae”) blooms and high 3- phosphate (PO4 ) concentrations have been implicated in the blooms, as phosphate is a typically a limiting nutrient. Further water Quality, and water chemistry testing, collected over 16 months (November, 2015 – March, 2016), provided insight into sources and cycling of phosphate in the lake and its watershed. Advanced analyses such as the ratio of total nitrogen to total phosphorous (TN:TP), X-ray absorption spectra (XAS) of lake bottom sediments, and d18O of phosphate were applied as tracers of phosphate source and cycling.

  • MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG the SAN ANDREAS FAULT from MUSSEL ROCK to the CENTRAL SANTA CRUZ MOUNTAINS by Earl H
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG THE SAN ANDREAS FAULT FROM MUSSEL ROCK TO THE CENTRAL SANTA CRUZ MOUNTAINS, CALIFORNIA By E. H. Pampeyan Menlo Park, California Open-File Report 93-684 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, product, or firm names in this publication is for descriptive purposes and does not imply endorsement by the U.S. Government. 1995 MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG THE SAN ANDREAS FAULT FROM MUSSEL ROCK TO THE CENTRAL SANTA CRUZ MOUNTAINS by Earl H. Pampeyan PURPOSE OF THIS MAP This map shows the location of lineaments and other geomorphic features interpreted to be the result of historic or relatively recent breaks within the San Andreas Fault Zone. It was compiled primarily to provide information for those concerned with land use and development on or in the fault zone, but it should also be useful in scientific studies of faulting and earthquakes. The lines on the map mark the location of suspected displacements of the ground surface by rupture along the San Andreas Fault. Map users should keep in mind that these lines are primarily guides for locating fault traces on the ground and are not necessarily located with the precision needed for every engineering or land-use project. THE SAN ANDREAS FAULT AND FAULT ZONE The San Andreas Fault Zone is a major structural break in the earth's crust that can be traced for more than 600 miles from the head of the Gulf of California in northern Mexico through western California.

  • Landslide Classification, Characterization and Susceptibility Modeling in Kwazulu- Natal
    LANDSLIDE CLASSIFICATION, CHARACTERIZATION AND SUSCEPTIBILITY MODELING IN KWAZULU- NATAL. by Rebekah Gereldene Singh Supervisors: Prof T McCarthy and Dr G.A. Botha A dissertation submitted to the Faulty of Science, University of the Witwatersrand, Johannesburg, in fulfillment of the requirements for the Degree of Master of Science 2009 DECLARATION I declare that this dissertation is my own, unaided work. It is being submitted for the Degree of Master of Science in the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination in another University. The information used in the dissertation has been obtained while employed by the Council for Geoscience. _______________________________ (Signature of candidate) __________ day of ___________________________________ 200_____ ABSTRACT In eastern South Africa landslides are widespread owing to the dramatic topographic-, climatic-, geological- and geomorphological-gradients across the region. In the KwaZulu-Natal (KZN) province numerous landslides and associated deposits are geohazards that represent threats to development and strategic infrastructure. The regional landslide inventory and susceptibility mapping project, following international classification systems and modeling techniques, has revealed the widespread occurrence of landslides. Landslide types mapped include; falls, topples, flows, translational and rotational slides. The bivariate statistical landslide susceptibility modeling method and Analytical Hierarchy Process (AHP) was used to evaluate landslide susceptibility, using a Geographic Information System (GIS). The huge size of some palaeo-landslides mapped is a revelation in the context of KwaZulu-Natal where recent landslide events are mainly small features triggered by intense rainfall events affecting embankments and steep hillslopes. Radiocarbon dating of organic material derived from sag ponds yielded minimum ages for the large middle to late Holocene landslide events.

    13—22 Eiszeitalter u. Gegenwart 32 Hannover 1982 3 fig., 1 tab. Neotectonics of a Segment of the San Andreas Fault, Southern California (USA) CARLOS SCHUBERT *) Morphology, neotectonic, San Andreas fault, fault scarp, fault trenche, bassin, sedimentation, alluvium, marshes, peat bog, pond, landform description, Cenozoic, stratigraphic column. California, Littlerock-Cajon Pass Region Abstract : The San Andreas fault between Valyermo and Wrightwood is characterized by a principal fault trace marked by fault scarps and trenches, tectonic depressions filled with alluvium, marshes, peat bogs, and ponds; displaced and offset drainages, shutterridges and offset ridges, fault gouge zones, fault benches, springs, vegetation contrasts, and trees affected by earth­ quakes. Secondary fault traces diverge and rejoin the principal trace, and are characterized by lithologic contrast across them, aligned valleys, and fault gouge zones. The minimum right-lateral offset, probably due in part to the 1857 Fort Tejön earthquake, is 20 m; right-lateral offset of drainages and shutterridges ranges between 20 and several hundreds of meters. The distribution of Older Alluvium (Late Pleistocene?) suggests an approximate cumulative right-lateral offset of 3.5 km.

  • Section 4.6 Wetlands
    Section 4.6 Wetlands 4.6.1 Introduction This section describes existing conditions related to wetlands and other bodies of water in the vicinity of the WSX Alternative. The section also analyzes the WSX Alternative’s potential impacts on wetlands and other waters and identifies mitigation measures to address substantial adverse impacts. 4.6.2 Affected Environment 4.6.2.1 Methodology for Assessment of Existing Conditions The area studied for the analysis of wetlands encompassed the 5.4-mile-long approximately 100-foot- wide WSX Alternative corridor, an access road along Morrison Creek, New Marsh, and an adjacent biological resource area. This is referred to as the wetlands study area. Inventory of Existing Information As preparation for the field surveys, Jones & Stokes biologists, independent scientists retained by BART to evaluate project effects, conducted a search of pertinent existing literature to evaluate the potential for sensitive wetlands habitats to occur in the biological resources study area. The following sources of information were used in the pre-field inventory. Pertinent environmental documents, including the following. Lake Elizabeth Stivers Lagoon Marsh Design and Improvement Program, Draft Environmental Impact Report (City of Fremont 1993a). Lake Elizabeth Stivers Lagoon Marsh Design and Improvement Program, Final Environmental Impact Report (City of Fremont 1993b). Biological Resource Assessment for the Grimmer Boulevard and Irvington Pump Station Sites Owned by San Francisco Public Utilities Commission (Environmental Collaborative for Baseline Environmental Consulting 2000). Jones & Stokes staff also consulted individuals recognized as experts in biological issues relevant to the wetlands study area. These individuals are listed in the personal communications section in Chapter 10, References.
