Authorize the City Manager, or his designee, to prepare and execute all necessary documents. BACKGROUND: The STP is needed to resolve critical infrastructure and capacity deficiencies in the eastern part of the 69 kV subtransmission network. Riverside Public Utilities (RPU) hired Power Engineers, Inc.to prepare an Initial Study and Mitigated Negative Declaration (MND) under the California Environmental Quality Act (CEQA). City Council approved the MND and STP at their meeting on May 19, 2009. The STP includes the construction and reconstruction of 4.8 miles of twin circuit transmission lines and is being constructed in phases. Preliminary work at Hunter Substation that rearranged and reconstructed 0.3 miles of twin 69 kV transmission lines was completed in February 2010.
