City approves $1.66 million contract for rubberized slurry treatments on key Cathedral City streets
Summary
Council approved a contract with Petrochem Materials Innovation to apply rubberized emulsion aggregate slurry (RIAS) on East Palm Canyon Drive, District streets and other corridors, with a 15% contingency raising the total encumbrance to $1,659,000.
Cathedral City council voted March 26 to award a construction contract to Petrochem Materials Innovation LLC (PMI) to apply rubberized emulsion aggregate slurry (RIAS) across multiple street segments and neighborhood areas.
Andrew Lee of the Engineering Department told the council the treatment is a preventive maintenance method to extend pavement life and reduce further deterioration. He said PMI is the sole provider of Central Mix RIAS in Southern California and that the company’s unit cost is about $0.85 per square foot, including traffic control, crack sealing, minor asphalt repairs and striping.
The contract covers four project areas: East Palm Canyon Drive (from the western city limits to Cathedral Canyon Drive, excluding areas already in other projects), Assessment District 865 neighborhood streets, Vista Chino Drive (western city limits to just east of Panorama Drive) and Deep Palm Drive (East Palm Canyon Drive to Gerald Ford Drive, excluding the bridge). Staff recommended a 15% contingency; PMI’s proposal amount was just under $1.5 million and the total recommended encumbrance including contingency is $1,659,000. Funding sources include maintenance-of-effort, Assessment District 865 and Measure A funds.
“Riaz is a preventative maintenance treatment to treat minor faults, reducing further deterioration,” Lee said during his presentation. Council members thanked staff for prioritizing street work and said the projects align with the city’s strategic goal of community investments.
A member of the public from the Cove noted his neighborhood is currently under utility work and asked that the final surfacing be completed properly; the speaker sought assurance the streets would be returned to good condition. Staff explained the project areas and how crack repairs would be handled before slurry application.
Council member Gregory moved and Council member Lam seconded the staff recommendation. The motion carried unanimously.
