<div style='text-align:Left;'><div><div><p><span>Under contract to the California Department of Fish and Wildlife (CDFW), the North State Planning and Development Collective (NSPDC) created a fine-scale vegetation map of portions of the Sierra Nevada mountains around Lake Tahoe and the adjacent Modoc Plateau. CDFW’s Vegetation Classification and Mapping Program (VegCAMP) provided in-kind service to allocate and score the Accuracy Assessment. </span></p><p><span>The mapping study area consists of approximately 1.6 million acres, covering portions of Sierra, Plumas, Placer, Nevada, Modoc, and Lassen counties. Work was performed on the project between 2019 and 2023. The purposes of the project include assisting land managers in decision-making, fire and fuel management, protecting endangered species and habitats, protecting cultural and natural resources, habitat connectivity, habitat restoration, conservation prioritization, and informed development. NSPDC staff conducted 434 Rapid Assessment and Releve surveys across the mapping area in the summer of 2019 to gather vegetation data to be used in the development of a vegetation classification for the project area.</span></p><p><span>VegCAMP developed the floristic vegetation classification used for the project. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS).</span></p><p><span>The vegetation map was produced applying heads-up digitizing techniques using a 2018 base of one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 1 acre; exceptions are made for wetlands and riparian types, which were mapped to a 1/4 acre. Breaks on overstory cover were done at 3 acres.</span></p><p><span>Field reconnaissance and the Accuracy Assessment enhanced the overall map quality. There were a total of 107 mapping classes. The overall Fuzzy Accuracy Assessment rating for the final vegetation map</span><span><span>,</span></span><span>at the Alliance, Group, and Macrogroup levels, is 81.7% percent</span><span>.</span></p><p><span /></p></div></div></div>

Map Sheet 48 (2025 update) - Ground Motion from PGA (2% in 50 years)

<div style='text-align:justify;'>This image service is part of a collection of maps for PGA, PGV and spectral accelerations at 0.2 s (SA02), 1.0 s (SA10), and 2.0 s (SA20) to illustrate seismic hazards in California. For each ground motion parameter, maps at two different hazard levels were presented: one with a 2% probability of being exceeded in 50 years (equivalent to 2,475-year recurrence interval) and the other with 10% probability of being exceeded in 50 years (equivalent to 475-year recurrence interval). The ArcGIS Online interface allows users to select any two ground motion hazard maps to compare side by side. Ground motion parameters were calculated using the 2023 update of the U.S. Geological Survey National Seismic Hazard Model.

2014 Georgiana Slough Floating Fish Guidance Structure Performance Evaluation - GSNPB-14_Legacy_Reports v2

In an effort to identify potential engineering approaches to reduce the percentage of salmonids that migrate from the Sacramento River into Georgiana Slough, DWR implemented a large-scale testing program in 2011 and 2012 to assess the effectiveness of a non-physical barrier design (i.e., a Bio-Acoustic Fish Fence, or BAFF). The experimental design of the 2011 and 2012 tests used acoustically tagged juvenile Chinook salmon and steelhead (2012 only), released upstream of the BAFF when the barrier was ‘On’ and ‘Off’ (i.e., in operation or not in operation, respectively), to determine the effectiveness of the barrier. In 2014, a physical barrier called a Floating Fish Guidance Structure (FFGS) was tested, with methods similar to those used during the testing of the BAFF barriers in 2011 and 2012. This report presents the results of the tests conducted in 2014 using the FFGS (2014 GSFFGS Study).
