The project involves improvements to camping units, infrastructure, restrooms, and other facilities to meet the most current U.S. Forest Service (USFS) design and accessibility standards of the Architectural Barriers Act, at the Caples Lake and Silver Lake East campgrounds. The improvements are being conducted in accordance with requirements of USFS Conditions 50.1 and 50.2 of EID’s Federal Energy Regulatory Commission license to operate Project No. 184. The project includes: 1) resurfacing and expanding campground roadways and parking spurs; 2) replacing, expanding, and relocating camping units; 3) replacing the potable water systems; 4) replacing restrooms and other facilities; and 5) abandoning and/or removing existing camping units, pipelines, and other facilities. Project construction is anticipated to take approximately 10 months in fall 2019 and spring/summer 2020. The project site locations are not identified on the lists specified in Government Code section 65962.5 for hazardous waste sites. The project does not increase the capacity or change the existing use of the campgrounds. EID is the lead agency for the project, under the California Environmental Quality Act (CEQA), and has directed the preparation of an Initial Study (IS) on the proposed project in accordance with CEQA requirements, the State CEQA Guidelines, and EID’s guidelines. This IS describes the proposed project and assesses the proposed project’s potentially significant adverse impacts on the physical environment. It concludes that the proposed project’s potentially significant or significant adverse effects on the environment could be mitigated to less-than-significant levels; therefore, a proposed Mitigated Negative Declaration (MND) has been prepared. Agencies and members of the public are invited to comment on the proposed IS/MND. The comment period is from June 28, 2019 to July 29, 2019. The proposed IS/MND can be reviewed at EID’s Customer Service Building, 2890 Mosquito Road, Placerville, CA 95667 or on the EID web site at www.eid.org/ceqa. Comments can be sent to Doug Venable, EID Environmental Review Analyst, at the address above or by email at [email protected] by 5:00 p.m. on July 29, 2019. A public hearing to consider the IS/MND will be held on August 12, 2019 at 9:00 a.m. during a regularly scheduled meeting of the EID Board of Directors. The hearing will be in the EID Customer Service Building Board Room at the above address. Caples Lake and Silver Lake East Campground Improvements Project GEI Consultants, Inc.

Caples Lake and Silver Lake East Campground Improvements Project Notice of Intent NOI-2 El Dorado Irrigation District PROPOSED MITIGATED NEGATIVE DECLARATION Project: Caples Lake and Silver Lake East Campground Improvements Project Lead Agency: El Dorado Irrigation District PROJECT LOCATION The Caples Lake and Silver Lake East campgrounds are located in Alpine and Amador counties, California, respectively. A segment of the new water supply pipeline and offsite well serving the Silver Lake East Campground is located in El Dorado County, California. The project site locations are adjacent to State Route 88, near Caples and Silver lakes. PROJECT DESCRIPTION The project involves improvements to camping units, infrastructure, and restrooms, to meet the most current U.S. Forest Service (USFS) design and accessibility standards of the Architectural Barriers Act at the Caples Lake and Silver Lake East campgrounds. The improvements are being conducted in accordance with requirements of USFS Conditions 50.1 and 50.2 of El Dorado Irrigation District’s (EID’s) Federal Energy Regulatory Commission license for operation of Project No. 184. The project includes: 1) resurfacing and expanding campground roadways and parking spurs; 2) replacing, expanding, and relocating camping units; 3) replacing potable water systems; 4) replacing restrooms and other facilities; and 5) abandoning and/or removing existing camping units, pipelines, and other facilities. Project construction is anticipated to take approximately 10 months in fall 2019 and spring/summer 2020. FINDINGS An Initial Study (IS) was prepared to assess the proposed project’s potential effects on the environment and the significance of those effects. Based on the IS, it has been determined that the proposed project would not result in significant adverse effects on the physical environment after implementation of mitigation measures. This conclusion is supported by the following findings: 1. The proposed project would have no impacts on land use and planning, mineral resources, population and housing, public services, and wildfire. 2. The proposed project would have less-than-significant impacts on aesthetics, agriculture and forestry resources, air quality, greenhouse gas emissions, noise, recreation, transportation, and utilities and service systems. 3. The proposed project would have potentially significant impacts on biological, Tribal and cultural resources, geology and soils, hazards and hazardous materials, and hydrology and water quality, but mitigation measures are proposed to avoid or reduce these effects to less-than-significant levels. Caples Lake and Silver Lake East Campground Improvements Project GEI Consultants, Inc. El Dorado Irrigation District MND-1 Mitigated Negative Declaration 4. The proposed project would not have the potential to substantially degrade the quality of the environment; substantially reduce the habitat of a fish or wildlife species; cause a fish or wildlife population to drop below self-sustaining levels; threaten to eliminate a plant or animal community; substantially reduce the number or restrict the range of an endangered, rare, or threatened species; or eliminate important examples of the major periods of California history or prehistory. 5. The proposed project would not have the potential to achieve short-term environmental goals to the disadvantage of long-term environmental goals. 6. The proposed project would not have possible environmental effects that are individually limited but cumulatively considerable and contribute to a significant cumulative impact. “Cumulatively considerable” means that the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects. 7. The environmental effects of the proposed project would not cause substantial adverse effects on human beings, either directly or indirectly. Following are the proposed mitigation measures that would be implemented by EID to avoid or minimize environmental impacts. Implementation of these mitigation measures would reduce the environmental impacts of the proposed project to less-than-significant levels. Mitigation Measure BIO-1: Minimize Potential Impacts on Sierra Nevada Yellow-legged Frog EID shall implement the following measures to minimize potential for significant adverse effects on Sierra Nevada yellow-legged frog during project activities at the Silver Lake East Campground. Conduct environmental awareness training before project activities begin to inform all construction personnel about measures to avoid and minimize effects on biological resources. Install and maintain high-visibility fencing or other visual marking to protect sensitive biological resource areas (i.e., Oyster Lake and Oyster Creek) that are located adjacent to construction areas from encroachment by personnel and equipment. Incorporate sensitive habitat information into construction

Vegetation sensitive to temperature and hydroclimatic change tended to be basin-specific, though the expansion of shrubs and herbs universally signalled arid conditions, and landscpe conversion to steppe. Multi-proxy analyses were conducted on two cores from the Big Bear Valley in the San Bernardino Mountains to reconstruct a 125,000-year history for alpine southern California, at the transition between mediterranean alpine forest and Mojave desert. Age control was based upon radiocarbon and luminescence dating. Loss-on-ignition, magnetic susceptibility, grain size, x-ray fluorescence, pollen, biogenic silica, and charcoal analyses showed that the paleoclimate of the San Bernardino Mountains was highly subject to globally pervasive forcing mechanisms that register in northern hemispheric oceans. Primary productivity in Baldwin Lake during most of its ii history showed a strong correlation to historic fluctuations in local summer solar radiation values.

    table of contrents Sierra Nevada Forest Plan Amendment – Part 4.6 4.6. Vascular Plants, Bryophytes, and Fungi4.6. Fungi Introduction Part 3.1 of this chapter describes landscape-scale vegetation patterns. Part 3.2 describes the vegetative structure, function, and composition of old forest ecosystems, while Part 3.3 describes hardwood ecosystems and Part 3.4 describes aquatic, riparian, and meadow ecosystems. This part focuses on botanical diversity in the Sierra Nevada, beginning with an overview of botanical resources and then presenting a more detailed analysis of the rarest elements of the flora, the threatened, endangered, and sensitive (TES) plants. The bryophytes (mosses and liverworts), lichens, and fungi of the Sierra have been little studied in comparison to the vascular flora. In the Pacific Northwest, studies of these groups have received increased attention due to the President’s Northwest Forest Plan. New and valuable scientific data is being revealed, some of which may apply to species in the Sierra Nevada. This section presents an overview of the vascular plant flora, followed by summaries of what is generally known about bryophytes, lichens, and fungi in the Sierra Nevada. Environmental Consequences of the alternatives are only analyzed for the Threatened, Endangered, and Sensitive plants, which include vascular plants, several bryophytes, and one species of lichen. 4.6.1. Vascular plants4.6.1. plants The diversity of topography, geology, and elevation in the Sierra Nevada combine to create a remarkably diverse flora (see Section 3.1 for an overview of landscape patterns and vegetation dynamics in the Sierra Nevada). More than half of the approximately 5,000 native vascular plant species in California occur in the Sierra Nevada, despite the fact that the range contains less than 20 percent of the state’s land base (Shevock 1996).

    TERR–3 SPECIAL-STATUS PLANT POPULATIONS 1.0 EXECUTIVE SUMMARY During 2001 and 2002, the review of existing information, agency consultation, vegetation community mapping, and focused special-status plant surveys were completed. Based on California Native Plant Society’s (CNPS) Electronic Inventory of Rare and Endangered Vascular Plants of California (CNPS 2001a), CDFG’s Natural Diversity Database (CNDDB; CDFG 2003), USDA-FS Regional Forester’s List of Sensitive Plant and Animal Species for Region 5 (USDA-FS 1998), U.S. Fish and Wildlife Service Species List (USFWS 2003), and Sierra National Forest (SNF) Sensitive Plant List (Clines 2002), there were 100 special-status plant species initially identified as potentially occurring within the Study Area. Known occurrences of these species were mapped. Vegetation communities were evaluated to locate areas that could potentially support special-status plant species. Each community was determined to have the potential to support at least one special-status plant species. During the spring and summer of 2002, special-status plant surveys were conducted. For each special-status plant species or population identified, a CNDDB form was completed, and photographs were taken. The locations were mapped and incorporated into a confidential GIS database. Vascular plant species observed during surveys were recorded. No state or federally listed special-status plant species were identified during special- status plant surveys. Seven special-status plant species, totaling 60 populations, were identified during surveys. There were 22 populations of Mono Hot Springs evening-primrose (Camissonia sierrae ssp. alticola) identified. Two populations are located near Mammoth Pool, one at Bear Forebay, and the rest are in the Florence Lake area.
