Repavement on Stelling Road has caused heavily congested traffic, causing slow movements especially peak hours. Road construction is ongoing along two major thoroughfares, Stevens Creek and De Anza boulevards. The specific procedures done on these roads include rubberized chips seals and slurry seals.

Though Stelling has been rated a 76/100 Pavement Condition Index (PCI) score in 2014, construction was still approved, even with a score that is rated “very good (may require periodic minor maintenance)”.

Both projects aimed to resurface the aged and decrepit hot mix asphalt with more modern and cost-effective rubberized overlay. This project inadvertently interrupted the already steady flow of traffic entering and exiting Highway 85.

Improved safety by way of increased skid resistance and a less frequent service intervals are some of the objective benefits of this project.

The stretch between De Anza Blvd. and Wolfe Rd. on Stevens Creek, and Stevens Creek to Homestead Rd. on De Anza specifically received the retrofitted rubberized overlay treatment previously.

Previous projects completed in summer 2015 on Homestead Rd., Stelling Rd., Stevens Creek. Blvd. east of Bubb Rd. and Foothill Blvd. expanded traffic signal interconnect fiber optic networks, costed around $132,000. This Capital Improvement Plan by the City of Cupertino was approved in April 2015.

The City’s selected contractor –G. Bortolotto & Company, Inc., controls processes of milling of the edge of asphalt, leveling of the street surface with asphalt and/or full width overall of asphalt on streets.

Existing potholes and dangerously reflective patch lines are present on the surface of the street. Each divot and scratch are potential dangers to road users.

From 2009-2014, the annual pavement budget to maintain this asset of roadway networks (including state, federal and general fund contributions) has averaged $2.45 million. At this average funding level, the condition of the street network deteriorated and the amount of deferred maintenance increased, according to the City of Cupertino Public Works Department.
