Syphon Reservoir Access Road Improvement Project

Irvine Ranch Water District contractors will be constructing the first phase of a new access road to IRWD's Syphon Reservoir from Sand Canyon Avenue that will eventually replace the current access point through the Crean Lutheran High School Athletic Complex.

This phase of the new, paved access road will start at the north end of the intersection of Sand Canyon Avenue and Portola Parkway, identified as No. 1 on the map above, and follow the general contours of an existing dirt road to point No. 2. 

The project calls for about six to eight months of actual construction activity, most of which will occur on District property north of Portola. Some intersection roadwork will also occur at various points within the project’s yearlong timeframe.

Staff has worked withthe City of Irvine and Crean Lutheran High School to ensure the safety of students and pedestrians walking by the construction site, and motorists and bicyclists, through the use of city-approved traffice control measures such as concrete barriers and flag crews as needed. The westbound bicycle lane on Portola Parkway is expected to remain open at all times.

What: Construction of the first phase of a paved access road to the reservoir off Sand Canyon Avenue, along with associated intersection improvements.

Construction period: February to December, 2024

Construction hours: Monday through Friday, 9 a.m. to 3 p.m. in public right of ways; 7:30 a.m. to 4 p.m. within District property.
