Executive Summary

An H. T. Harvey & Associates ecologist surveyed the proposed location of a high-quality camping facility, the Tenaya Lodge Explorer Cabins (project), for jurisdictional features that may be subject to regulation under the Clean Water Act, as administered by the U.S. Army Corps of Engineers (USACE). The project lies on the western slope of the central Sierra Nevada, approximately 2.8 miles south of the southern entrance to Yosemite National Park and 12.6 miles north of Oakhurst (Figure 1). Specifically, 39.46 acres, hereafter referred to as the Wetland Delineation Boundary (WDB) or study area, were surveyed to identify potential waters of the United States (jurisdictional waters), including wetlands and other waters. This document describes the features delineated during the survey effort.

The delineation survey was performed on October 9, 10, 21, and 23 and November 3, 2014, and July 30, August 30, and November 24, 2015. The delineation was conducted primarily during a period of below-average rainfall, October 2014 through August 2015 (USACE 2010); however, rainfall was above average in the period of September through November 2015. The on-site determination based upon existing conditions present at the time of the surveys considered the atypical hydrologic conditions in the 2014 – 2015 wet season.

A total of 38 features (9.05 acres) meeting the definition of potentially jurisdictional wetlands or other waters were identified within the WDB: 10 wet meadow/freshwater emergent wetlands (3.78 acres), five white alder riparian wetlands (1.19 acres), three willow shrub riparian wetlands (1.00 acre), five aspen forested wetlands (0.77 acre), and 15 other waters features (2.31 acres). The remaining land within the study area (30.41 acres) comprises upland habitat that does not meet the definition of wetlands or other waters potentially subject to USACE jurisdiction. The table below provides a summary of the potential jurisdictional waters within the WDB.

Section 1. Introduction

1.1 Purpose of Report

H. T. Harvey & Associates performed a preliminary delineation of wetlands and other waters for the proposed location of a high-quality camping facility, the Tenaya Lodge Explorer Cabins Project (project). The Tenaya Lodge is an existing mountain resort set in forested lands near the southern gate of Yosemite National Park and adjacent to the Sierra National Forest in Fish Camp, California. Tenaya Lodge offers guest accommodations and conference facilities within a 249-room destination hotel and 53 rooms in 17 separate cottage buildings. The all-season resort offers onsite amenities and access to a range of recreational activities in the surrounding region. Tenaya Lodge is proposing to add up to 54 pre-manufactured cabins and a clubhouse on a site adjacent to and immediately to the north of the Tenaya Lodge. The objective of the proposed Tenaya Explorer Cabins Project is to provide a more rustic lodging option for guests with the conveniences of a resort while still allowing them to experience the natural beauty of the Sierra National Forest area in a minimally developed setting. The complete project description and site plans are provided in Appendix A.

The 39.46-acre Wetland Delineation Boundary (WDB) is larger than the Project Area Boundary (PAB; 28.74 acres) to better characterize wetland features and drainages. The purpose of the wetland delineation is to identify the extent and location of potentially jurisdictional wetlands and other waters occurring within the WDB.

1.2 Project Location

The project is on the western slope of the central Sierra Nevada, approximately 2.8 miles south of the south gate to Yosemite National Park and 12.6 miles north of Oakhurst (Figure 1). The project is located on the Fish Camp, Mariposa County, California, 7.5-minute U.S. Geological Survey (USGS) topographic map; in Sections 23, 24, and 26 of Township 5S and Range 21E (37.476538, -119.636704, decimal degrees) (Figure 2). Elevations on the project site range from approximately 4,970 to 5,211 feet above sea level. The WDB is located in the Big Creek Subwatershed (Hydrologic Unit Code 180400080203), in the larger South Fork Merced River Watershed (Hydrologic Unit Code 1804000802). Big Creek originates east of the WDB, flows south to north through the WDB, and eventually drains into the South Fork Merced River within Yosemite National Park to the north. The South Fork Merced River flows westward, eventually merging with the Merced River. The Merced River joins the San Joaquin River south of the City of Turlock.

The project site is bounded to the south by Tenaya Lodge at Yosemite, to the west by Highway 41, and to the north and east by private property, including single-family residences and the Green Meadows Outdoor School. The Sierra National Forest surrounds the community of Fish Camp.

1.3 Existing Conditions

The majority of the WDB is undeveloped, but has evidence of past uses. A system of unpaved roads provides access from Highway 41 to private property to the east. An old cement foundation and well provide evidence of former residential occupancy. Most of the WDB contains lower montane coniferous forest and consists mainly of mature trees with little understory. White fir (Abies concolor) and sugar pine (Pinus lambertiana) predominate, and incense cedar (Calocedrus decurrens) also occur in large numbers. The forest understory varies across the site from white fir and incense cedar seedlings and saplings to mixed shrub and herbaceous species, including green leaf manzanita (Arctostaphylos patula), western bracken fern (Pteridium aquilinum var. pubescens), sticky cinquefoil (Drymocallis glandulosa), and lupine (Lupinus sp.). In many areas, there is no understory and the ground is covered with leaf litter. Small clearings, meadows, and small rock outcrops occur throughout the forest. The southern portion of the WDB extends onto developed area of Tenaya Lodge due to the topography and local drainage patterns. The WDB also includes Highway 41 because project plans include installation of a turn lane, and improvements to both shoulders of the road.

A pond is located in the northwest corner of the WDB (Figures 2 and 5; Appendix B, Photo 1). County documents refer to the pond as the historic Rainbow Lake, a feature that has existed since before the 1930s (Mariposa County Planning Department 2009). An earthen dam on the northeast side of Rainbow Lake impounds water seeping from wet meadow areas to the south, and separates the primary ponding area from Big Creek. Overflow channels are present on the east-northeast side and northern corner of Rainbow Lake, carrying overflow to Big Creek.

The National Wetlands Inventory (NWI 2015) identifies five wetland features within the WDB (Figure 4). Rainbow Lake is identified as palustrine, unconsolidated bottom, permanently flooded, and diked/impounded. There also are two palustrine, emergent, saturated features, and two palustrine, scrub/shrub, temporarily flooded features (Figure 4) (NWI 2015).

There are two soil units mapped within the WDB (Figure 3, Table 1). The Chaix-Holland families complex, 15 to 35% slopes, soils are somewhat excessively to well drained and formed of residuum weathered from granodiorite (NRCS 2015a). The Waterwheel-humic dystroxerepts complex, 15 to 45% slopes, mountain slopes, frigid soils comprise two major soils (NRCS 2015a). Waterwheel soils are somewhat excessively drained and formed in colluvium derived from granitoid rock, and humic dystroxerepts are sandy, frigid soils that are well drained and formed in colluvium and minor amounts of till, primarily from granitoid rock and small amounts of metasedimentary rock. Appendix C provides a detailed description of the soil series in the WDB. Neither soil unit is considered hydric (NRCS 2015b).

Climate norms from 1981 through 2010 were estimated for the WDB using the Parameter-elevation Regressions on Independent Slope Model (PRISM), a high-spatial-resolution climate model. Based on modeled data, the mean annual low and high temperatures within the WDB are 40.26ºF and 64.51ºF, respectively, and mean annual precipitation is approximately 44.79 inches (PRISM Climate Group 2015). Precipitation data for the 2013-2014 rain year (September 2013–August 2014) indicate that the area received 21.64 inches of precipitation, which is 48% of the 30-year (1981–2010) average (PRISM Climate Group 2015). Precipitation data for the 2014-2015 rain year (September 2014–August 2015) indicate that the area received 22.67 inches of precipitation, which is 51% of the 30-year (1981–2010) average (PRISM Climate Group 2015). Preliminary data indicate 7.15 inches of precipitation between 1 September and 24 November 2015 (PRISM Climate Group 2015). Therefore, while the delineation was conducted primarily during a period of below-average rainfall, totals were above average in the period of September through November 2015. The on-site determination based upon existing conditions present at the time of the surveys considered the atypical hydrologic conditions in the 2014 – 2015 wet season (USACE 2010).

1.4 Contact Information and Directions to the Site

The project is being developed by Delaware North Companies Parks & Resorts, and the project contact is Brian Fulce, PE, Regional Project Manager (559-692-9343). The WDB is accessible through the main entrance of the Tenaya Lodge at 1122 Hwy 41, Fish Camp, CA, 93623. Additional access points are available immediately west of Highway 41, approximately 0.15 mile north of the Tenaya Lodge entrance, in Fish Camp, California (Figure 1).

Section 2. Methods

On October 9, 10, 21, and 23 and November 3, 2014, and on July 30, August 30, and November 24, 2015, H. T. Harvey & Associates plant and wetland ecologist Ethan Barnes, M.S., performed field surveys and mapping for the formal technical delineation of wetlands and other waters within the WDB. Potentially jurisdictional features were mapped in the field using a Trimble GeoXH™ Global Positioning System unit (Trimble GPS unit) capable of submeter accuracy. The entire 39.46-acre study area was surveyed on foot. The ecologist used digital aerial imagery overlain with the property boundary to identify and map all potentially jurisdictional features. In addition, a TruPulse 200 Laser Rangefinder was used to accurately measure the width of Big Creek from ordinary high-water mark (OHWM) to OHWM along transects.

The vegetation, soils, and hydrology of the study area were examined following the guidelines outlined in the “Routine Determinations” section of the Corps of Engineers Wetlands Delineation Manual (Corps Manual) (Environmental Laboratory 1987). In addition, the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (Regional Supplement) (USACE 2010) was followed to document site conditions relative to hydrophytic vegetation, hydric soils, and wetland hydrology. The Regional Supplement is designed for use with the current version of the Corps Manual except where it is superseded by instruction issued in the more recent and location-specific Regional Supplement.

This preliminary delineation also was prepared in accordance with guidance provided in Information Requested for Verification of Corps Jurisdiction (USACE 2007), Final Map and Drawing Standards for the South Pacific Division Regulatory Program (USACE 2012), and Minimum Standards for Acceptance of Aquatic Resources Delineation Reports (USACE 2016). These documents identify information that must be submitted as part of a request for a jurisdictional determination, which includes: locality map (Figure 1 of this preliminary delineation), USGS quadrangle sheets (Figure 2), WDB and aerial photograph (Figure 5), written rationale for sample point choice (Section 3.0, “Results and Discussion”), color photographs (Appendix B), wetland determination data forms (Appendix D), and applicable sections of the current soil survey report (Appendix C).

The study area was examined for topographic features, drainages, alterations to site hydrology or vegetation, and areas of significant recent disturbance. Then a determination was made as to whether normal environmental conditions were present at the time of the field surveys. Data were used to document which portions of the study area were wetlands. In general, surveys examined the vegetation, soils, and hydrology using the “Routine Determination Method, On-Site Inspection Necessary (Section D)” outlined in the Corps Manual and using the updated data forms, vegetation sampling methods, and hydric soil and hydrology indicators developed for the Regional Supplement (USACE 2010). This three-parameter approach to identifying wetlands assumes the presence of hydrophytic vegetation, hydric soils, and wetland hydrology. A two-parameter approach to identifying wetlands, which is used in situations in which the vegetation, soil, or hydrology indicator is absent as a result of human activities or natural events, is also available and is described in the “Difficult Wetland Situations in the Western Mountains, Valleys, and Coast Region” section (USACE 2010). Due to the seasonal

Tenaya Lodge Explorer Cabins: Preliminary H. T. Harvey & Associates 9 Delineation of Wetlands and Other Waters February 2016

conditions at the time of the survey (most plants senescent and covered by snow), a two-parameter approach focusing on soils and hydrology was used for sample points taken on November 24, 2015.

Before site surveys were conducted, topographic maps and aerial photographs of the study area were obtained from several sources and reviewed. These sources included USGS, the National Wetlands Inventory, and the Natural Resources Conservation Service (NRCS) and Google Earth software (Google Inc. 2015). The maps and aerial photographs of the study area were examined to identify topographic features, hydrologic patterns, and areas of significant past disturbance. Overall, the approach used to identify wetlands involved digging soil pits at sample points to identify hydric indicators, observing vegetative cover near the sampling location and identifying hydrophytic plant species, and determining current surface and subsurface hydrologic features present near the sampling location. Features meeting these criteria were mapped in the field using a submeter GPS Trimble GeoXH unit and augmented with aerial interpretation.

The USACE methods specifically applicable to the identification of jurisdictional waters on the site are summarized below.

2.1 Identification of Section 404 Wetlands

Forty-two sample points were placed in the areas most likely to delineate the extent of wetland and nonwetland indicators (Figure 5; Appendix D). At each sample point, methods included digging soil pits to evaluate the upper soil horizons, estimating cover by plant species, and noting hydrologic features as described below.

2.1.1 Vegetation

The H. T. Harvey & Associates ecologist compiled a list of plant species identified at each sample point and visually estimated the percent cover of species, following guidance provided in the Regional Supplement (USACE 2010). Plants observed at each of the sample points were identified to the lowest taxonomic level possible using The Jepson Manual: Vascular Plants of California, second edition (Jepson Manual) (Baldwin et al. 2012). The wetland indicator status of each species was identified using the Western Mountains, Valleys, and Coast 2014 Regional Wetland Plant List (Lichvar et al. 2014). The recent revision of plant names in the Jepson Manual led to several differences in nomenclature between the Jepson Manual and the regional wetland plant list. Where there were differences, the ecologist searched recognized synonyms for the species to find the correct wetland indicator status. It was then determined which of the observation areas supported wetland vegetation. To accomplish this task, the ecologist used the applicable indicator (i.e., 1: Dominance Test, 2: Prevalence Test, or 3: Morphological Adaptations) as described in the Regional Supplement.

Wetland indicator species are designated according to their frequency of occurrence in wetlands. For instance, a species with a presumed frequency of occurrence of 67–99% in wetlands is designated a facultative wetland indicator species. The wetland indicator categories, indicator symbols, and frequency of occurrence of species in wetlands are presented in Table 2.

Indicator Category Symbol Frequency of Occurrence (%) Obligate OBL >99 Facultative wetland FACW 67–99 Facultative FAC 34–66 Facultative upland FACU 1–33 Upland UPL <1

Source: Environmental Laboratory 1987.

Obligate and facultative wetland indicator species are hydrophytes that occur “in areas where the frequency and duration of inundation or soil saturation produce permanently or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present” (Environmental Laboratory 1987). Facultative indicator species may be considered wetland indicator species when they are found growing in hydric soils that experience periodic saturation. A complete list of the vascular plants observed in the study area and their current indicator status are presented in Appendix E. Plant species that are not on the regional list of wetland indicator species (NI) are considered upland species.

2.1.2 Soils

Where possible, the top 22 inches of the soil profile were examined for diagnostic hydric soil indicators as described by the National Technical Committee for Hydric Soils (NRCS 2015b). These indicators included the presence of Histosols (A1) (organic soils), histic epipedons (A2), hydrogen sulfide odor (A4), depleted matrix (F3), redox depressions (F8), redox dark surface (F6), and mottling indicated by the presence of gleyed or bright spots of colors (in the former case, blue grays; in the latter case, orange red, or red brown) in the soil horizons observed, among other features.

Munsell soil notations (Munsell 2009) were recorded for the soil matrix for each soil sample (Appendix D). The last digit of the soil notation refers to the chroma of the sample. This notation consists of a number ranging from 0 for neutral grays to a maximum of 20 for stronger color saturation. Soil matrix chroma values that are 1 or less, or 2 or less when mottling is present, are typical of soils that have developed under anaerobic conditions. The first digit of the Munsell soil notation refers to the value of the sample, with the number ranging from 2 for saturated colors to 8 for faded or light colors. Hydric soils often show low-value colors when soils have accumulated organic material sufficient to indicate development under wetland conditions, but they can show high-value colors when iron depletion has occurred, which removes color value from the soil matrix.

The NRCS Web Soil Survey (2015a) was consulted to determine which soil types have been mapped within the WDB. A list of hydric soils of the United States was also consulted to determine whether hydric soils have been mapped within the WDB (NRCS 2015b).

Tenaya Lodge Explorer Cabins: Preliminary H. T. Harvey & Associates 11 Delineation of Wetlands and Other Waters February 2016

2.1.3 Hydrology

Each of the sample points was examined for positive field indicators (primary and secondary) of wetland hydrology (Appendix D), following the guidance provided in the Regional Supplement. Primary indicators include visual observation of surface water (A1), high water table (A2), soil saturation (B1), water-stained leaves (B9), and hydrogen sulfide odor (C1). Secondary indicators include riverine drift deposits (B3), drainage patterns (B10), and passing score for the FAC-neutral test (D5).

2.2 Identification of Section 404 Other Waters

Historically, in nontidal waters, USACE jurisdiction extends to the OHWM, which is defined in Title 33, Code of Federal Regulations, Part 328.3 as “the line on the shore established by the fluctuations of water and indicated by physical characteristics, such as a clear, natural line impressed on the bank, shelving, changes in the character of the soil, destruction of terrestrial vegetation or the presence of litter and debris.” There is no hydrologic definition of the OHWM.

In addition, Regulatory Guidance Letter 05-05 (dated December 7, 2005) specifically addresses the topic of OHWM identification (USACE 2005). The letter lists the following physical characteristics that should be considered when making an OHWM determination: (1) natural line impressed on the bank; (2) shelving; (3) changes in the character of the soil; (4) destruction of terrestrial vegetation; (5) wracking; (6) vegetation matted down, bent, or absent; (7) sediment sorting; (8) leaf litter disturbed or washed away; (9) scour; (10) deposition; (11) multiple observed flow events; (12) bed and banks; (13) water staining; and (14) and change in plant community.

The project site is located in the southernmost portion of the Western Mountains, Valley, and Coast Region and thus, like the Arid West, has a high degree of seasonal and interannual variability in precipitation. USACE has refined its methods and indicators for delineating the OHWM in this region and has published A Guide to Ordinary High Water Mark (OHWM) Delineation for Non-Perennial Streams in the Western Mountains, Valley and Coast Region of the United States (Mersel and Lichvar 2014). Accordingly, the guidance provided in the publication was applied during this study. The lateral extent of other waters was determined by the presence of one or more natural geomorphic field indicators, and the determination took into consideration such factors as size of the watershed, channel slope, landscape setting, elevation, gradient, land use practices, and soil type.

For purposes of the current study, the OHWM was identified in the field based on observation of a suite of natural geomorphic field indicators that have formed during channel-forming events. These features included staining of rocks and culverts, erosion of soil to bedrock, and channel bed morphology, among other factors. The presence of one or more of the natural geomorphic field indicators was taken as direct evidence of an OHWM, and such channels were identified as other waters. Factors such as size of watershed, channel slope, landscape setting, elevation, gradient, land use practices, and soil type were considered during the evaluation of natural geomorphic field indicators.

Section 3. Results and Discussion

The 42 sample locations and the locations of potentially jurisdictional waters (depicted as the extent of ordinary high water for streams and drainages, wetlands, and other features) are shown on the preliminary identification of waters of the United States map (Figure 5).

Thirty-eight features (totaling 9.05 acres) meeting the definition of potentially jurisdictional wetlands or other waters were identified within the WDB: 10 wet meadow/freshwater emergent wetlands (3.78 acres), five white alder riparian wetlands (1.19 acres), three willow shrub riparian wetlands (1.00 acre), five aspen forested wetlands (0.77 acre), and 15 other waters features (2.31 acres). The remaining land in the study area (30.41 acres) is upland habitat that does not meet the definition of wetlands or other waters potentially subject to USACE jurisdiction. Table 3 below provides a summary of the type and acreage of each of these categories.

3.1 Areas Meeting the Regulatory Definition of Jurisdictional Waters

3.1.1 Section 404 Potentially Jurisdictional Wetlands (Special Aquatic Sites)

Potentially jurisdictional wetlands were identified on 6.74 acres of the study area (Figure 5). Data collected at the 42 sampling points indicated that 16 of the points meet USACE’s three-parameter definition of wetlands. Specifically, the potentially jurisdictional features were 3.78 acres of wet meadow/freshwater emergent wetlands (WM/FEW), 1.19 acres of white alder riparian wetland (WARW), 1.00 acre of willow shrub riparian wetland (WSRW), and 0.77 acre of aspen forested wetland (AFW) (Figure 5; Appendix F). These features are described below.

3.1.1.1 Wet Meadow/Freshwater Emergent Wetlands

This wetland category is represented by 10 features (WM/FEW1 through WM/FEW10) within the WDB (Figure 5). These features include two seasonal wet meadows and two perennial wet meadows, totaling 3.78 acres and described in detail below.

3.1.1.1.1 Seasonal Wet Meadow

Two seasonal wet meadows are located in the northwestern portion of the study area. One seasonal wet meadow (WM/FEW9, Figure 5; Appendix B, Photo 2) occupies 0.49 acre (Appendix F) and is located in a shallow swale that drains into Rainbow Lake. This feature intergrades with the perennial wet meadow surrounding Rainbow Lake where the soils remain saturated for longer periods. Sample points SP4, SP5, and SP16 (Appendix D) are located in this seasonal wet meadow feature. A second seasonal wet meadow (WM/FEW8, Figure 5; Appendix B, Photo 3) occupies 0.04 acre (Appendix F) and is located under lower montane coniferous forest canopy along the western portion of the site. Sample point SP1 (Appendix D) is located in this seasonal wet meadow feature.

Vegetation. The seasonal wet meadows on the site are dominated by facultative plant species. The northern seasonal wet meadow is vegetated with Canada goldenrod (Solidago canadensis) (FACU), rusty sedge (Carex subfusca) (FAC), black bent (Agrostis gigantea) (FAC), and a patch of American cow parsnip (Heracleum maximum) (FAC) (Appendix B, Photos 2 and 3). The current regional drought has possibly muted signatures of wetland vegetation, allowing upland vegetation to increase in the feature.

Soils. The hydric soil indicators, which were present at four sample locations, were sandy redox (S5) based on observed redox concentrations (SP1, SP4, and SP5) (Appendix B, Photo 4), sandy mucky mineral (S1) (SP1), and red parent material (TF2) in one pit (SP16). The soil in the seasonal wet meadows is Chaix-holland families complex, 15–35% slopes (124) (Figure 3).

Tenaya Lodge Explorer Cabins: Preliminary H. T. Harvey & Associates 16 Delineation of Wetlands and Other Waters February 2016

Hydrology. The primary hydrological indicator, oxidized rhizospheres along living roots (C3), was observed at each wetland sample location (SP1, SP4, SP5, and SP16) in these features. The landscape position is appropriate to support saturation, and hydric soils were present. Precipitation, surface runoff, and subsurface flow are apparently the main sources of hydrology.

3.1.1.1.2 Perennial Wet Meadow

Two perennial wet meadows are present in the study area. A 2.60-acre perennial wet meadow (WM/FEW5 through WM/FEW7 and WM/FEW10, Figure 5; Appendix B, Photos 5 and 6) is present along the southern portion of the study area in a swale. Sample points SP14, SP22, SP31, SP38, SP39, and SP41 (Appendix D) are located in this seasonal wet meadow feature. The 0.65-acre perennial wet meadow (WM/FEW1 through WM/FEW4, Figure 5; Appendix B, Photo 1) surrounds Rainbow Lake in the northwestern portion of the study area. No sample points were located in this feature.

Vegetation. The vegetation in the perennial wet meadows on site is hydrophytic. The southern perennial wet meadow is dominated by red-tinged bulrush (Scirpus microcarpus) (OBL) and Sierran checkerbloom (Sidalcea reptans) (OBL), with tall scouring rush (Equisetum hyemale ssp. affine) (FACW) increasing in frequency near Big Creek (Appendix B, Photos 5 and 6). The northern feature adjacent to Rainbow Lake is dominated by Nebraska sedge (Carex nebrascensis) (OBL) (Appendix B, Photo 1).

Soils. The hydric soil indicators, present at five sample points, were sandy gleyed matrix (S4) (SP41), sandy redox (S5) (SP14 and SP41), depleted matrix (F3) (SP31), and redox dark surface (F6) (SP38 and SP39) (Appendix B, Photos 7, 8, and 9). The soil at one sample point (SP22) consisted of recently deposited sand associated with the Big Creek floodplain. Figure 3 depicts the soil as Chaix-Holland families complex, 15–35% slopes (124).

Hydrology. Primary indicators of wetland hydrology observed included saturation (A3) (SP39 and SP41), water-stained leaves (B3) (SP22), and oxidized rhizospheres along living roots (C3) (SP14, SP31, SP38, and SP41). Secondary indicators of wetland hydrology observed included drainage patterns (B10) (SP39 and SP41), geomorphic position (D2) (SP22, SP31, SP38, SP39, and SP41), FAC-neutral test result (D5) (SP22 and SP31), and nearby frost-heave hummocks (D7) (SP14 and SP38). The landscape positions are appropriate to support saturation, and hydric soils are present. Precipitation, surface runoff, and subsurface flow are apparently the main sources of hydrology.

3.1.1.2 Freshwater Forested/Scrub Riparian Wetland

This wetland category contains a collection of 13 varied features (WARW1 through WARW5, WSRW1 through WSRW3, and AFW1 through AFW5) within the WDB (Figure 5). These features consist of white alder riparian wetlands, willow shrub riparian wetlands, and aspen forested wetlands. They are described in detail below.

Tenaya Lodge Explorer Cabins: Preliminary H. T. Harvey & Associates 17 Delineation of Wetlands and Other Waters February 2016

3.1.1.2.1 White Alder Riparian Wetland

White alder riparian wetlands are present within the WDB along Big Creek in a discontinuous strip on the banks and is intermixed with alder/white fir/incense cedar riparian forest (Figure 5). White alder riparian wetlands is present on 1.19 acres (WARW1 through WARW5, Figure 5; Appendix B, Photo 10) of the study area. Sample point SP9 (Appendix D) is located in this feature.

Vegetation. The vegetation in the white alder riparian wetlands is hydrophytic. White alder (Alnus rhombifolia) (FACW) is the dominant overstory tree, and the understory is dominated by tall scouring rush (Appendix B, Photo 10).

Soils. Hydric soil indicators in the on-site white alder riparian wetlands meet the sandy redox criteria (S5) based on observed redox concentrations (Appendix B, Photo 11). Figure 3 depicts the soil in this area as Chaix- Holland families complex, 15–35% slopes (124).

Hydrology. The primary hydrological indicator, oxidized rhizospheres along living roots (C3), and secondary hydrological indicators drainage patterns (B10), geomorphic position (D2), and FAC-neutral test result (D5) were observed in this wetland type. The landscape position is appropriate to support saturation and occasional inundation during high-flow periods of Big Creek, and hydric soils are present. Source hydrology is flooding from Big Creek, precipitation, surface runoff, and subsurface flow.

3.1.1.2.2 Willow Shrub Riparian Wetland

Three areas dominated by shrubby Pacific willow (Salix laevigata var. lasiandra) are located within the WDB (Figure 5). These wetlands total 1.00 acre (WSRW1 through WSRW3, Figure 5; Appendix B, Photo 12) in the riparian corridor of Big Creek. Sample points SP11, SP19, SP23, SP24, and SP26 (Appendix D) are located in these features.

Vegetation. The willow shrub riparian wetland is dominated by the hydrophytes Pacific willow (FACW), tall scouring rush, and rusty sedge (Appendix B, Photo 12).

Soils. Hydric soil characteristics meet the sandy redox criteria (S5) based on observed redox concentrations at three sample points (SP11, SP19, and SP26). Characterization of soils at two sample points (SP23 and SP24) was problematic because of their location on a floodplain adjacent to the stream. Figure 4 depicts the soil as either Chaix-Holland families complex, 15–35% slopes (124), or waterwheel-humic dystroxerepts complex, 15– 45% slopes, mountain slopes, frigid (285yp).

Hydrology. The primary wetland hydrology indicators of saturation (A3) (SP24), drift deposits (B3) (SP24), and oxidized rhizospheres on living roots (C3) (SP11 and SP19), and the secondary hydrological indicators of drainage patterns (B10) (SP19, SP23, and SP26), geomorphic position (D2) (SP11, SP19, and SP23), and FAC- neutral test result (D5) (SP19, SP23, SP24, and SP26) were observed. The landscape position is appropriate to

Tenaya Lodge Explorer Cabins: Preliminary H. T. Harvey & Associates 18 Delineation of Wetlands and Other Waters February 2016

support saturation and occasional inundation during high-flow periods of Big Creek. Source hydrology is from Big Creek, precipitation, surface runoff, and subsurface flow.

3.1.1.2.3 Aspen Forested Wetland

Several groves of quaking aspens (Populus tremuloides), with an understory similar to the wet meadow habitat described above, occur within the WDB (Figure 5). These wetlands, which total 0.77 acre (AFW1 through AFW3, Figure 5; Appendix B, Photos 5 and 13), are located near the southeastern boundary in the low swale that drains into Big Creek. Sample point SP21 (Appendix D) is located in these features.

Vegetation. The vegetation in the aspen forested wetlands is hydrophytic. The features support aspens (FACU), with an understory similar to the perennial wet meadow habitat described above (Appendix B, Photos 5 and 13).

Soils. Hydric soil characteristics met the sandy redox criteria (S5) based on observed redox concentrations at SP21. Figure 3 depicts the soil as Chaix-Holland families complex, 15–35% slopes (124).

Hydrology. The secondary indicators of wetland hydrology observed at SP21 were geomorphic position (D2), FAC-neutral test result (D5), and nearby frost-heave hummocks (D7). Although no saturation was observed at the sample point, standing water and saturation were present at the time of the surveys in October and November 2014 in the two southern aspen stands. Source hydrology is likely precipitation, surface runoff, and subsurface flow.

3.1.2 Identification of Other Waters

Potentially jurisdictional other waters were delineated within the WDB (Figure 5). Other waters extend to the OHWM and were indicated by physical characteristics such as a clear, natural line impressed on the bank or the presence of standing water. Specifically, these features included 1.06 acres of freshwater pond (FP), 1.10 acres of perennial stream (PS), 0.02 acre of intermittent stream (IS), 0.10 acre of drainage channel (DC), and 0.03 acre of culvert (C) (Figure 5; Appendix F). The total lengths of these features were approximately 1,953 feet of perennial stream, approximately 180 feet of intermittent stream, approximately 662 feet of drainage channels, and approximately 327 feet of culvert. These features are described below.

3.1.2.1 Freshwater Pond

In the northwestern corner of the site, a perennially flooded freshwater pond (Rainbow Lake) formed by an earthen dam on the east side impounds water seeping from seasonal wet meadow areas to the south (Section 3.1.1.1.1, above) and from a larger unnamed watershed north of Highway 41. The dam separates Rainbow Lake from Big Creek. A channel near a rock outcropping on the east-northeast side of Rainbow Lake and a channel in the northern corner carry overflow to Big Creek (described below in Section 3.1.2.3). The OHWM of Rainbow Lake is shown as FP1 in Figure 5 (Appendix B, Photo 1). Rainbow Lake has a sandy bottom with a layer of silt. The edges are gradually sloping with little reduction in water level observed. The bottom of

Tenaya Lodge Explorer Cabins: Preliminary H. T. Harvey & Associates 19 Delineation of Wetlands and Other Waters February 2016

Rainbow Lake appears to be level and less than 3 feet deep, suggesting that sediment has filled the pond over the years.

3.1.2.2 Perennial Stream

Big Creek is a naturally occurring feature along the eastern portion of the study area (Appendix B, Photo 14). The OHWM of Big Creek is shown as PS1 in Figure 5. The OHWM was delineated using GPS. Width from OHWM to OHWM was measured along 10 transects (OHW-1 through OHW-9, Figure 5) for accuracy and ranged from 8 to 31 feet wide. At the time of each survey, Big Creek contained flowing water. The perennial stream has riffles, runs, and pools up to 2 feet deep. Substrate is primarily cobble and rock, with boulders and shores of dirt, cobble, or sand. Green algae was observed growing on mud substrate in some larger pools. Most of the bank on one side of the creek (alternating sides) is undercut with complex tunnels, alcoves, clumps of vegetation, and exposed roots. The channel has some off-channel pools and side channels, and a moderate amount of large woody debris was observed in the channel. Pools were clear enough to see to the bottom.

3.1.2.3 Intermittent Stream

One small intermittent stream drains the perennial wet meadow into Big Creek. The OHWM of the intermittent stream is shown as IS1 and IS2 in Figure 5. This stream is fed primarily by groundwater in the wet meadow, and at the time of the surveys in October and November 2014, it contained approximately 3 inches of stagnant water (Appendix B, Photo 15). This stream is located in an incised channel with a mud bottom, approximately 2–3 feet deep and approximately 3 feet wide, and flows through a culvert (C4) under an unimproved road. The stream is surrounded by tall scouring rush.

3.1.2.4 Drainage Channel

Six drainage channels are located within the WDB. The OHWMs and extent of the drainage channels are shown as DC1 to DC6 in Figure 5. Two drainage channels act as overflow channels for Rainbow Lake, one on each side of the dam. At the time of the surveys in October and November 2014 and July and August 2015, the drainage channels did not contain water. DC2 is connected to Rainbow Lake, whereas DC1 drains water through a subsurface connection (no culvert was apparent). A third channel, DC3, carries flow from a culvert (C5) under Highway 41 into the perennial wet meadow. Vegetation in the channels was representative of adjacent wetland or upland habitat.

The other three drainage channels are located on the Tenaya Lodge property. The OHWMs of the drainage channels are shown as DC4, DC5, and DC6 in Figure 5. One upland sample location (SP42, Figure 5; Appendix D) was located in DC4 (Appendix B, Photo 16). Drainage channel DC5 is filled with riprap, whereas Drainage channel DC6 has a more natural bed (Appendix B, Photos 17 and 18, respectively). The hydrology of these drainage channels is supported primarily by rainfall. They channel runoff from the developed areas, such as the parking lot, collect water from overland and subsurface flow, and deliver it to the meadow at WM/FEW7. At the time of the survey in November 2015, portions of these drainage channels contained flowing water, attributable to the snowmelt occurring in the study area.

Tenaya Lodge Explorer Cabins: Preliminary H. T. Harvey & Associates 20 Delineation of Wetlands and Other Waters February 2016

3.1.2.5 Culvert

Together, the five culverts in the study area occupy 0.03 acre (Figure 5). The culverts are corrugated metal pipes, and several have metal aprons installed below the outlets to prevent erosion and scouring.

A 3-foot-diameter culvert carries water under the south end of a dirt road that crosses the wet meadow, allowing vehicle traffic to cross from the Tenaya Lodge property to the proposed Explorer Cabins site. It is depicted as C1 in the inset of Figure 5 (Appendix B, Photo 19). The presence of this culvert, and the associated channelization in the wetland above and below the road, appears to have reduced the extent of the adjacent perennial wet meadow. Three culverts, shown as C2, C3 and C4 in Figure 5, are located on the Tenaya Lodge property. They allow runoff under unpaved roads and function with drainage channels DC4, DC5, and DC6 to channel water off the property. At the time of the survey in November 2015, these culverts contained flowing water, attributable to the snowmelt occurring in the study area. One culvert (C5) carries water under an unimproved road, connecting the intermittent streams IS1 and IS2 (Figure 5). Another culvert (C6) runs under Highway 41 and flows into DC3.

3.2 Areas Not Meeting the Regulatory Definition of Jurisdictional Waters

Most of the study area (30.42 acres) is upland habitat that does not meet the regulatory definition of jurisdictional waters (Figure 5). Data on vegetation, soils, and hydrology were obtained from 24 upland sample points (SP2, SP3, SP6 through SP8, SP10, SP12, SP13, SP15, SP17, SP20, SP25, SP27, SP28 through SP30, SP32 through SP37, SP40, and SP42, Figure 5; Appendix D).

Most of the study area is vegetated by lower montane coniferous forest (Appendix B, Photo 20; SP2, SP3, SP6 through SP8, SP10, SP12, SP13, SP15, SP17, SP20, SP25, SP27, SP29, SP30, and SP32 in Appendix D). White fir and sugar pine predominate, and incense cedar is present in large numbers. Ponderosa pine (Pinus ponderosa) and California black oak (Quercus kelloggii) are sparse. The forest understory varies across the site, ranging from white fir and incense cedar seedlings and saplings to mixed shrub and herbaceous species, including green leaf manzanita, western bracken fern, sticky cinquefoil, and lupine. In many areas, there is no understory, and the ground is covered with leaf litter. Small clearings, meadows, and small rock outcrops are present throughout this community. Included in the upland habitat type are unimproved roads and disturbed areas.

Two unimproved (dirt) roads run north-south across the perennial wet meadow along the south-central portion of the study area. The western road near Highway 41 (SP28, SP34, SP37, and SP40), connecting the Tenaya Lodge property with the proposed Explorer Cabins site to the north, is loamy sand fill in the wetland (Figure 5; Appendix B, Photos 21 and 22; Appendix B). The road is elevated approximately 3 feet above the wetland, lower in the north and higher in the south. Indicators of wetland vegetation, soils, and hydrology were not observed in the road. A culvert (C1) allows water to flow from the west side of the road to the east (see Section 3.1.2.5, above). The second road runs east-west through the wet meadow and aspen wetland. This road crosses the intermittent stream (IS1 and IS2) via culvert C5. It is unknown when either of these roads was installed.

An extensive riparian corridor along the banks of Big Creek is composed of a mix of the wetland habitats described above and upland alder/white fir/incense cedar riparian habitat. Developed areas associated with the lodge include paved roads, parking lots, lodge buildings and associated facilities, a wastewater treatment plant, wells, and landscaping of native and exotic plants.

Tenaya Lodge Explorer Cabins Project

Project Description

Background

The Tenaya Lodge is an existing mountain resort set in forested lands near the southern gate of Yosemite National Park and adjacent to the Sierra National Forest in Fish Camp, California. Tenaya Lodge offers guest accommodations and conference facilities within a 249-room destination hotel and 53 rooms in 17 separate cottage buildings. The all-season resort offers onsite amenities and access to a range of recreational activities in the surrounding region. Tenaya Lodge is proposing to add up to 54 pre-manufactured cabins and a clubhouse on a site adjacent to and immediately to the north of the Tenaya Lodge. The objective of the proposed Tenaya Explorer Cabins Project is to provide a more rustic lodging option for guests with the conveniences of a resort while still allowing them to experience the natural beauty of the Sierra National Forest area in a minimally-developed setting.

Project Location

The Tenaya Explorer Cabins Project site is located at 1152 State Highway 41 in the unincorporated community of Fish Camp in Mariposa County. The project is located on private property immediately north of the Tenaya Lodge, between Highway 41 to the west and Big Creek to the east. The existing Fish Camp community is a small residential development of private homes, vacation homes, vacation rentals and resort commercial uses. Fish Camp is primarily developed along Highway 41 and is situated approximately one mile from the south entrance to Yosemite National Park.

Key Concepts

The site is forested and bordered by wetlands, meadows, rock formations, Rainbow Lake, Big Creek and State Highway 41. The project site plan was designed to accommodate the existing topography of the site and minimize the impacts to existing natural features.

Key concepts considered while laying out the site plan included the following:

1. Minimize encroachment into trees, vegetation, rock formations and wetlands to better enhance the wilderness experience.

2. Maximize the distance between the proposed Cabins and Rainbow Lake at the north end of the parcel.

3. Maximize the separation and visual screening between cabins.

N ote 1 - -- The initial parcel calculation concluded that the property area is 24.82 acres, which differs from the title report and assessor ’s par cel map. The area of 26.89 acres, as identified on the assessor’s parcel map, is being confirmed at this time. This discrepancy will be reconciled when a boundary survey is performed.

4. Position the cabins away from Highway 41 to create a visual and sonic buffer.

5. Position some of the cabins in groups to create a communal space for group gatherings with fire pits.

6. Place the vehicle parking areas in clusters and maintain visual separation between parked vehicles and the cabins whenever possible. Position parking areas in the buffer between the cabins and Highway 41.

7. Position cabins to provide clear views of the creek and meadow areas whenever possible.

8. Incorporate a common Clubhouse building to be used for registration, administration, retail and special events.

Project Components

Parking and Access

The natural topography of the site and the locations of the existing dirt access roads were considered when determining the locations of the proposed access roads and parking areas. Roads and parking areas were routed around existing trees, vegetation and rock formations whenever possible to maximize visual screening and enhance the wilderness experience.

Access roads will be paved with asphalt and designed in compliance with Mariposa County standards for slope, width, turning radius and fire department access.

The proposed site plan provides 1.5 parking stalls for each cabin plus seven additional parking stalls to account for retail, office and associate parking in accordance with the Fish Camp TPA Specific Plan. This will result in 88 parking stalls. One wheelchair accessible stall would be located near the clubhouse and parking would be clustered, as shown on the site plans, to maintain visual separation between parked vehicles and the cabins.

Vehicular access to the site will be from Highway 41 at the same location as the existing entrance to the site. The entrance will be configured to meet Caltrans requirements for acceleration and deceleration distances and turning lane requirements.

Year-round emergency access would be provided to both Parcel 1 and Parcel 2 through the construction of the onsite access roads, which have been designed in compliance with emergency access requirements. A second access point will be constructed off Highway 41 between the main entrance and Rainbow Lake. This access point will be used for emergency ingress and egress only and a chain or gate will be provided to discourage use of the road outside of the intended purpose.

Pathways will be constructed to connect the cabins to the clubhouse and the clubhouse to the existing Tenaya Lodge. There is an existing trail and roadway system on Tenaya’s property that

will be connected to the cabins project via a boardwalk. The pathway system will be used by guests and employees for housekeeping, room service, etc. Use of electric carts may be used by employees for work related activities as well as shuttling guests between the two properties.

Clubhouse Building

The Clubhouse will be a multi-use building that will be used for guest registration, administrative offices and recreational activities. Other activities such as continental breakfast, happy hour and gatherings such as weddings and banquets could also be conducted there. The building will also contain laundry facilities, vending machines, a small retail grocery section and a residential-style kitchen.

The Clubhouse will be adjacent to Big Creek on the eastern boundary of the project and will include a large outdoor deck, fire pit, barbeque, hot tub and swimming pool. The Clubhouse has been designed to accommodate seating for 60 people on the deck and will include indoor facilities capable of holding smaller parties.

Food served at the Clubhouse will be prepared at the Tenaya Lodge kitchen or another off-site location, as the Clubhouse will not be equipped with commercial kitchen facilities. Outdoor events may use amplified sound and will conclude by 10:30 pm.

Cabins and Utilities

The project will include installation of up to 54 pre-fabricated cabins set on concrete pier footings or concrete slab-on-grade foundations. Each cabin will have an area of approximately 675 square feet and will be connected to sanitary sewer, potable water, electricity, telephone, data, and cable television services. Underground utilities will be installed within the limits of the paved access roads whenever possible and will comply with separation standards set by the State of California and the Mariposa County Health Department.

Wastewater would be collected with a below-grade piping system located under the proposed project roads and gravity fed to a lift station located near the low point of the property. From the lift station, wastewater would be pumped to the new Tenaya Lodge Wastewater Treatment Plant (WWTP) located south of the project site on the southwestern side of the Tenaya Lodge and South of the cottages and Jackson Road. The new WWTP was designed with capacity to treat a daily average maximum of 80,000 gallons per day of wastewater which includes the proposed cabins project.

Water for domestic and fire fighting purposes will be provided by Tenaya’s existing water system. Fire hydrants will be located adjacent to the paved access road per the requirements of Mariposa County Fire Department. Additional water storage will be provided adjacent to the existing water tank at the Tenaya Lodge. The additional water storage will be connected to Tenaya’s existing water and fire system to provide additional fire water storage for the Lodge as well.

Electrical, telephone, data and cable television service will be extended from existing facilities close to the project and will be installed in a joint trench within the proposed access road whenever possible.

A propane tank or tanks will be utilized to fuel the fire pits shown on the site plan.

Landscaping

The conceptual site plan was designed to limit disturbance and removal of trees, vegetation, and rock formations. Therefore, there would be limited need for landscaping. Any new landscaping would utilize vegetation native to the region, therefore blending with the existing onsite vegetation. Vegetation would be drought-tolerant and if any irrigation would be needed, it would be supplied by tertiary-treated effluent (recycled water) from the new Tenaya Lodge wastewater treatment plant.

Snow Storage

The Fish Camp area experiences relatively heavy snowfall during most winter seasons. Therefore, snow removal is necessary to ensure that roads, pedestrian pathways, parking, and related areas are clear to provide pedestrian and vehicular access throughout the Tenaya Cabins site and to Parcel 2. The site plans identify snow storage areas, which would be onsite within the privately-owned property. Snow removal would be the responsibility of Delaware North. Best management practices (BMPs) would be installed at snow storage areas, and all snowmelt would be diverted to the onsite drainage system. It is not anticipated that any off-haul of snow would be needed, as there is ample onsite undeveloped land for snow storage.

Residential Parcel Dedication

The proposed project includes a land division of APN 010-350-008 into “Parcel 1” for the Tenaya Cabins Project, and “Parcel 2” for a single-family residential home. The two parcels are shown on the site plan. Parcel 1 would be rezoned from Single Family Residential 1-acre to Resort Commercial. Parcel 2 would be rezoned from Single Family Residential 1-acre to Single Family Residential ½-acre per Fish Camp Town Planning Area (TPA) Specific Plan and Mariposa County requirements. The Fish Camp TPA Specific Plan would be amended to reflect the changed land classifications.

No development is currently proposed for Parcel 2, the ½-acre residential parcel. However, it is assumed that a single residence would be built on the site in the future. Therefore, for purposes of this EIR, roadway access and provision of all necessary utilities to Parcel 2 are considered in the environmental impact analyses.

1 Cowardin et al. (1979) code: PEM1B = Palustrine, Emergent, Persistent, Saturated. PEM1E = Palustrine, Emergent, Persistent, Seasonally Flooded/Saturated. PSS1A = Palustrine, Scrub/Shrub, Broad-Leaved Deciduous, Temporarily Flooded.

PUB3Hh = Palustrine, Unconsolidated Bottom, Mud, Permanently Flooded, Diked/Impounded. R3UB1H = Riverine, Upper Perennial, Unconsolidated Shore, Cobble-Gravel, Permanently Flooded. R4SB5J = Riverine intermittent, Streambed, Mud, Intermittently Flooded. R4SB5/7Jr = Riverine intermittent, Streambed, Mud/Vegetated, Intermittently Flooded, Artificial.

2 Waters type abbreviations and definitions: RPW = relatively permanent waters (RPWs) that flow directly or indirectly into traditional navigable waters (TNWs). RPWWD = wetlands directly abutting RPWs that flow directly or indirectly into TNWs. RPWWN = wetlands adjacent to, but not directly abutting, RPWs that flow directly or indirectly into TNWs. NRPW = non-RPWs that flow directly or indirectly into TNWs. NRPWW = wetlands adjacent to NRPWs that flow directly or indirectly into TNWs.
