WHAT TO EXPECT DURING SLURRY SEAL

  • Please use alternate travel routes, as possible, to avoid delays associated with construction.

  • Final work is focused on slurry sealing Entler Ave. to finalize roadway rehabilitation.

  • During slurry sealing, work will be done one lane at a time, leaving one lane open for traffic. Follow flaggers for traffic control.

  • No on-street parking is allowed beginning March 30th and for 48 hours after slurry work is complete.

  • Please park on alternate streets during slurry work.

  • Vehicles may track slurry material onto nearby streets.

  • Some construction-related noise and odor can be expected.

  • You will always have access to your property, but there may be delays when work is immediately in front of your property. Please plan ahead.

  • After slurry seal is applied, it is normal to see loose aggregate (small rocks) on the roadway. This will improve as the pavement cures and through scheduled street sweeping.

FREQUENTLY ASKED QUESTIONS

What is slurry seal?
Slurry seal is a protective surface treatment made of asphalt emulsion, aggregate, and water. After application, the surface must cure while the water evaporates. Click here to watch a quick video about the process.

What can we expect after slurry seal application?
Loose aggregate (small rocks) following slurry seal application is normal and expected. Drivers and residents may notice loose material immediately after work is completed. This will improve as the pavement cures and through scheduled street sweeping.

Will there be any street sweeping?
The contractor will perform multiple rounds of sweeping. If loose aggregate appears excessive, residents are encouraged to contact the project team to review the location and determine whether additional sweeping is needed.

Will our trash be picked up during normal pickup days?
Trash bins should be placed out as usual on scheduled pickup days. The contractor will coordinate as needed to maintain service.

PROJECT OVERVIEW

In May 2025, the City of Chico, Public Works Department’s contractor began installing a trunkline sewer main. The new trunkline main is along Midway, Chico-Durham Bike Path and Entler Avenue, south of City limits. This important project is a critical infrastructure improvement to our wastewater collection system.

  • Properties will not be moved from septic to the trunk line. There are no changes to properties’ current connections.

  • You will always have access to your property during construction.

  • Traffic controls will be in place near construction areas, anticipate traffic delays and use alternative routes.

  • Work includes trenching, drilling and paving. Some noise impacts can be expected.

  • Please use alternate travel routes, as possible, to avoid construction delays.

  • Construction is anticipated to take place from May 2025 to into Spring 2026.

WHAT IS A TRUNKLINE?

A trunkline is a large diameter pipe that transports wastewater from a sewer main line. Sewer main lines connect to private connections. Trunklines do not connect to private sewer lines. At this time, the City of Chico does not have plans to install a sewer main in this project area.

Properties will not transition from septic to sewer as part of this project.

PROJECT BACKGROUND

The P-18 Trunkline Sewer Project was identified in the 2013 City of Chico Sanitary Sewer Master Plan Update, which identified capacity deficiencies in the sanitary sewer system and included plans to incorporate additional infrastructure where needed. This project is an important step toward improving sanitary sewer capacity.

The trunkline will service the majority of the Honey Run/Doe Mill Special Planning Area, South Entler Special Planning Area, and commercial and industrial uses in the area, as identified in the Chico 2030 General Plan.

This project is funded with U.S. Department of Housing and Urban Development Community Project Funding, American Rescue Plan Act Funding and local funds.
