YH-Valley Overhead Power Lines: Stables, YVL 1000's Housing
Yosemite National Park » YH-Valley Overhead Power Lines: Stables, YVL 1000's Housing » Document List
The National Park Service is preparing a Categorical Exclusion (CE) to update the outdated and unsafe electrical system at the Yosemite Valley concessioner stables and associated housing. This CE also includes actions at the Yosemite Valley Lodge 1000s Cabins; however, this Floodplain Statement of Findings only includes analysis of the actions within a floodplain and therefore does not reference the actions at the 1000s Cabins. This project aims to relocate power and telecom lines from trees and old utility poles to new poles. The current setup, which relies on "tree connects" and outdated infrastructure, does not meet safety standards for clearance or installation. By replacing these connections with poles and upgrading the infrastructure, safer and more reliable electrical service will be ensured for both employees and guests. While the option to install underground electrical utilities has been considered ideal, the necessary overhaul of this infrastructure may not be timely enough to address the urgent safety concerns.
The electrical infrastructure will be updated by installing ten new treated wood power poles, ranging from 20 to 36 feet in height. All power and telecom lines currently attached to trees will be relocated to new poles. Two existing poles will be replaced, new risers will be installed at the comfort station and stables office, and new service masts will be set up for nine hard-sided residences. An old pole and service riser in the wagon room will be removed.
To facilitate this project, one live cedar tree that is leaning and unhealthy will be removed, along with three dead, topped trees. Additionally, the lower branches of three healthy cedars will be trimmed to ensure proper clearance for the new installations.
The height of the new power poles will depend on their location and the necessary clearance for the lines. A 20-foot pole requires a 2' x 4' hole for installation, while a 36-foot pole needs a 3' x 6' hole. Excavated soil will be repurposed to fill around each pole and compacted for stability.
