BACKGROUND INFORMATION
Critical facilities and emergency systems need continuous back up power on a 24-hour basis, which is successfully provided by generators. Although solar panels are a reliable source of power during peak sun hours, they do not provide the required power at night or during cloudy days to properly support the continuous power requirement for these facilities. The recommended action will award a construction contract to Proterra Builders, Inc., for the Padua, Mt. Pass, & Sandy projects (Projects), which are located in San Bernardino County and Los Angeles County at communications sites leased from American Tower Corporation.
The scope of work at the Padua Project requires demolition of an existing generator and all its components, belly tank, Automatic Transfer Switch (ATS), and Manual Transfer Switch (MTS), together with the installation of a new emergency backup power generator with a belly tank, new ATS, and new MTS with Cam-Lock (an interchangeable electrical connector), and minor electrical work. This project site is located in Claremont, California.
The scope of work at the Mt. Pass Project requires the demolition of the existing ground tank, MTS, exhaust duct, silencer, day tanks, and racks, as well as installation of a new emergency backup power generator and all its components, new concrete equipment pad, and minor electrical work. The Mt. Pass Project site is located north of Baker, California
The scope of work at the Sandy Project requires the installation of a new emergency backup power generator with all its components, demolition of the existing concrete pad and placement of a new concrete equipment pad, and minor electrical work. The Sandy Project site is located in Midway, California.
The proposed generators will provide reliable and cost-effective electrical power during power outages to support the signal transmission from the site to multiple first responders, including but not limited to San Bernardino County Fire Protection District, Sheriff/Coroner/Public Administrator and Emergency Medical Responders, thereby supporting the County and Chief Executive Officer’s goals and objectives of improving County Government Operations and Operate in a Fiscally-Responsible and Business-Like Manner.
On May 24, 2022 (Item No. 70), the Board of Supervisors (Board) found the Project to be categorically exempt from further review under Section 15303, Class 3 Subsection (d), New Construction or Conversion of Small Structures, relative to electrical improvements, of the California Environmental Quality Act Guidelines (CEQA, Title 14, California Code of Regulations), and directed the Clerk of the Board to file and post the Notice of Exemption for the Project. No additional CEQA review is required at this time.
This Project is consistent with County Administrative Office approved CIP request Nos. 20-206, 20-205 & 20-208.
