Irvine Ranch Water District contractors are replacing 1,200 feet of recycled water pipeline along the west side of University Drive and through the intersection of University and Culver drives.

Project summary: The project involves the excavation of portions of University Drive (indicated in yellow) and Culver Drive (indicated in red). This work is necessary to replace the pipeline and to relocate it where it is more accessible.

When: Mid-September through November.

Project impacts: The sidewalk, bike lane and outside lanes of southbound University Drive will be closed throughout most of the project. Temporary lane closures on Culver Drive will occur in the initial stages of the project.

  • The eastbound and left turn lanes of Culver Drive will be closed sequentially over a period of approximately five days (lower red circle on the map).
  • Westbound lanes on Culver Drive will be closed sequentially over a period of approximately five days (upper red circle on the map).

Construction hours: 9 a.m. to 3 p.m. Monday through Friday; 9 a.m. to dusk on Saturday.
