Document Title
Advanced Metering Infrastructure (AMI) Implementation Project
Document Type
NOE - Notice of Exemption
Document Description
Upgrade the City's water meter reading technology from Automated Meter Reading (AMR) to Advanced Metering Infrastructure (AMI). AMR requires City staff to drive by monthly to collect water usage, whereas AMI will enable water usage data to be transmitted to the City directly, eliminating the need for staff to drive by each meter. The work includes replacing the existing register and endpoint of approximately 18,500 water meters, obtaining their GPS location, identifying the pipe material of water service lines, and replacing the water meter box lid with an AMI compatible polymer lid. The project will establish a Customer Engagement Portal (CEP) which will enable the City to effectively detect leaks within its water system while allowing customers to monitor and track their own water usage.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Article 19: Section 21084; Class 15301 (Existing Facilities) and Class 15302 (Replacement or Reconstruction)
Reasons for Exemption
The project consists of upgrading the existing water meters within the City of Petaluma's service area to the AMI technology. The project will reduce time, labor, cost, energy, and Greenhouse Gas emissions compared to the existing AMR system which requires Water Service Representatives to drive by each meter. Accordingly, there is negligible or no expansion of use beyond what currently exists, the AMI replacement will result in a benefit to the environment and there are no cumulative impacts, unusual circumstances or other factors that would make the exemption inapplicable pursuant to CEQA Guidelines section 15300.2. Therefore, the project is categorically exempt pursuant to Section 15301 Existing Facilities and Section 15302 Replacement or Reconstruction. City Council approved the project on April 8, 2024.
