Riverside Public Utilities

McKinley Grade Separation & Waterline Relocation Project

About the Project

The City of Corona is undergoing design and construction of the McKinley Grade Separation Project along McKinley Street, between Magnolia Avenue and the 91 Freeway. Existing Riverside Public Utilities’ water system infrastructure within McKinley Street, Estelle Street, and Magnolia Avenue will be relocated to allow for the design and build of the grade separation. The waterline relocations will improve the operation and reliability of Riverside Public Utilities’ water system by replacing aged water pipelines currently in use in the area.

Anticipated Project Timeline & Details

When: Summer 2021 through Fall 2022

Waterline relocation work in the public right-of-way will generally occur on weekdays during normal business hours.  Portions of the onsite work will occur at nighttime to minimize inconveniences to the public.

The work will not affect customer’s water service.  However, customers in the vicinity of project will be notified by mail before construction starts and as the work progresses.  Work will be executed in segments to minimize disruptions to traffic, and detours will be provided where necessary.  Driveway access to properties will remain open.


Project Benefits

  • Improved water system reliability
  • Improved fire flow
  • Improved operational efficiencies
