ENVIRONMENTAL ISSUES I. AESTHETICS. ENVIRONMENTAL SETTING The topography, flora, water features, and climate combine to create the aesthetic character of Emerald Bay State Park (SP). Chapter 3 provides an overview of the park’s environmental setting and a brief reiteration of regional features affecting the park’s aesthetic resources is included below. Lake Tahoe is a large, high elevation (approximately 6223 ft.) lake in the Sierra Nevada Mountains. The Lake Tahoe Basin is renowned for its natural beauty and Lake Tahoe is recognized as an Outstanding National Resource Water by the U.S. Environmental Protection Agency’s Water Quality Standards Program and the Clean Water Act. Rugged peaks, forested slopes, and the clear, blue waters of the lake characterize the scenery. The lake sits in a basin encompassed by the Crystal Range to the west and the Carson Range to the east. The border between California and Nevada divides the lake. Lake Tahoe Basin is approximately 20 miles southwest of Reno, Nevada and approximately 80 miles northeast of Sacramento, California. Emerald Bay is an embayment in the southwest corner of Lake Tahoe with a narrow inlet separating the bay from the lake. Emerald Bay is a unique, high profile attraction in the Lake Tahoe basin and is a primary destination for photographers, boaters, campers, hikers, and other recreationists. Formed through glacial activity in the last ice-age, the bay is approximately 1.7 miles long and 2/3 mile wide at the widest point (total surface area of approximately 704 acres). Emerald Bay SP is located around Emerald Bay, a National Natural Landmark since 1968 (DPR 1990). It is immediately south and contiguous with D. L. Bliss SP. The park contains the only island in Lake Tahoe - Fannette Island. In 1994, the California Department of Parks and Recreation (DPR) included the surrounding water of the bay as a part of the park, making Emerald Bay one of the first underwater parks of its type in the state. The park is accessible by State Route 89 near the southwest shore of the lake. The unit is 663 land acres in size, with the underwater area in and adjacent to Emerald Bay covering an additional 870 acres. There is approximately 14,130 feet of shoreline along Lake Tahoe. The California Legislature initiated the California Scenic Highway Program in 1963, with the goal of preserving and protecting the state’s scenic highway corridors from changes that would reduce their aesthetic value. The state laws governing the Scenic Highway Program are found in the Streets and Highways Code, Section 260 et seq. The State Scenic Highway System consists of eligible and officially designated routes. A highway may be identified as eligible for listing as a state scenic highway if it offers travelers scenic views of the natural landscape, largely undisrupted by development. Eligible routes advance to officially designated status when the local jurisdiction adopts ordinances to establish a scenic corridor protection program Asian Clam Control Project IS/MND Emerald Bay State Park California Department of Parks and Recreation 16
and receives approval from the California Department of Transportation. In El Dorado County, State Route 89 is a designated scenic highway along the southwest portion of Lake Tahoe. WOULD THE PROJECT: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? c) Substantially degrade the existing visual character or quality of the site and its surroundings? d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? LESS THAN POTENTIALLY SIGNIFICANT LESS THAN SIGNIFICANT WITH SIGNIFICANT NO IMPACT MITIGATION IMPACT IMPACT DISCUSSION a) Impacts to the scenic vista from deployment and removal of benthic barriers will consist of temporary boat use at the mouth of Emerald Bay. Boats are a very common fixture in the bay so this will not change the scenic vista. The black benthic barriers may be visible by boaters traveling in and out of the bay, but a fine sediment layer typically covers the barriers within days, making the barriers difficult to see unless specifically looking for them, resulting in less than significant impacts. b) Work will occur under the surface of the water and a considerable distance from state scenic Highway 89. No impact. c) Barrier deployment will be temporary in nature and the barriers will be installed and removed during a period of six to 20 24 months. The existing visual character of the site will not be permanently altered. No impact. d) The project does not create a new source of light or glare. No impact.
