La Sierra Avenue Reconstruction & Slurry Seal
Limits: Cajalco Road to El Sobrante Road
Length: Approximately 2.3 miles
District: 1
Community: Lake Mathews
The County of Riverside Transportation Department is proposing to reconstruct and slurry seal approximately 2.3 miles of La Sierra Avenue from Cajalco Raod to El Sobrante Road. The reconstruction portion will be from Cajalco Road to approximately 5,000 feet north of Cajalco Road and the slurry seal portion will be from 5,000 feet north of Cajalco Road to El Sobrante Road. La Sierra Avenue is classified as a Mountain Arterial in the County of Riverside’s General Plan. La Sierra Avenue is a two lane road and currently ranges from 26-66 feet wide with dike along various segments of the roadway. The proposed project will include removing the roadway, cement stabilizing the soil, followed by placing back Hot Mix Asphalt (HMA) in the reconstruct limits and applying microsurfacing 2 in the slurry seal limits.
Additional improvements include:
Removing excess material along the guardrail
Re-grading of the shoulder to drain and a safety edge
Reconstruction of guardrail including addition of reflective markers
Minor paved shoulder widening
Application of center line and edge line rumble strip
Utility/facility adjustments
Striping of roadway, including pavement markers and reflectors
Salvage/removal and installation of new signs
No additional right-of-way will be required to construct the proposed improvements. The project improvements will not be within the existing footprint of the roadway and will not raise the existing roadway profile.
