Final Striping along 9th Street Anticipated to Occur Next Week

The City has approved its Downtown Sewer Upgrade contractor’s request to finalize striping, signage and curb painting along the 9th Street corridor next Thurs., Dec 27 and Fri., Dec 28 (subject to sub-contractor’s availability). This striping work is necessary to keep motorists and bicyclists safe and aware of all structural changes and improvements to the street.

Remaining punch list items will be deferred until after the first of the year and are expected to be complete by mid-January 2019.


The Downtown Sewer Upgrade provides relief from existing conditions and planned development on an over-taxed and aging Combined Sewer System. This existing system provides sewer and storm drain needs for 7,500 acres in the City including Downtown, East Sacramento, River Park, Land Park, Curtis Park, and Oak Park neighborhoods. 

Once complete, the Downtown Sewer Upgrade will provide the following improvements:
