SLO in Motion Update – July 4, 2026

Sewer line work is continuing on Chorro and Islay Streets.

Here’s a look at the work planned for the coming weeks as we continue improving neighborhoods across the city with projects that enhance safety, accessibility, and connectivity.

Work to upgrade vital infrastructure and enhance the reliability, capacity, and safety of our water and sewer system is underway. See what areas we’re working on below.

Higuera Street: We expect to wrap-up well development work. We’ll be continuing storm drain repairs at Mariposa Drive and Las Praderas Drive. Commuters can expect minimal traffic impacts due to no parking in the areas. Monitoring well work is happening in different locations on Higuera Street from Los Osos Valley Road to High Street to help track the condition of the City’s groundwater.

Islay Sewer Replacement: We expect to begin trench work to start pulling out the current sewer line to get ready to replace it with new pipes for the next couple of months. Work is anticipated to start on Chorro Street between Buchon and Islay Streets and will be happening one block at a time. Work will be Monday – Friday from 7 a.m. – 4 p.m.

Construction will continue onto Islay Street from Chorro to Santa Rosa Streets, then later to Leff Street. During construction, commuters and pedestrians can expect traffic impacts due to lane closures, flagging, sidewalk closures, and intermittent road closures with detours.

Righetti Community Park: We’ll be continuing on-site foundational work such as grading and retaining wall work. We also expect to start plumbing work for the park restroom as soon as next week. Community members can expect minimal traffic impacts due to vehicles and equipment moving in and out of the area. Pedestrians can expect sidewalk closures with detours. Standard construction hours will be 7 a.m.– 4 p.m.

Mission Plaza Enhancement: Finishing touches like landscaping work and small outstanding items are continuing for the project at the Mission Plaza. Commuters can expect little to no traffic delays in the project area. Pedestrians will have sidewalk access.

Please keep an eye out for orange cones and active construction sites and remember to:

Allow Extra Travel Time: Due to ongoing construction, it’s a good idea to allow for extra travel time when navigating these areas.

Slow Down for Construction Crews: Remember to reduce your speed and exercise caution when driving through construction zones. Our dedicated crews are working diligently to make San Luis Obispo safer for everyone.

While exact schedules are subject to change due to weather or other unplanned conditions, the City of San Luis Obispo is committed to keeping the community informed as construction progresses. Your support and patience have been invaluable as we work to enhance the transportation options in San Luis Obispo. Thank you!
