The project involves the reconfiguration of existing distribution electrical facilities within the El Portal Administrative Site. The Yosemite Institute is currently in the process of constructing a replacement residential structure on Lot 42 , also known as 5627 Foresta Raod. As part of that approved construction (see 2007-072 El Portal Yosemite Institute 5627 Foresta Raod; Deconstruction and Rebuild #18912) the existing electrical service to the previous residence was to be removed and replaced with a new underground electrical service from an existing electrical pole. Upon examination of the existing distribution load to the existing residences as well as the existing NPS potable water storage tank was unbalanced. The situation needed to be corrected before the new electrical service could be provided to the new Yosemite Institute residential structure.
