Cajalco Road Widening and Safety Enhancement Project

Widen Cajalco Road from two to four lanes between Harvill Avenue to the east and Temescal Canyon Road to the west, and from four to six lanes between the Interstate 215 (I-215) southbound ramps and Harvill Avenue

Update – January 2014

The Riverside County Transportation Department is continuing its study of alignments for the widening of Cajalco Road from two to four lanes between Harvill Avenue and Temescal Canyon Road, and from four to six lanes between the I-215 southbound ramps and Harvill Avenue. Two alignments previously were identified for study and presented to the public during scoping meetings held in September 2011 and October 2012. Based upon the feedback received from residents and public agencies, two additional alignments have been identified for study. The project team is preparing technical studies related to the four alignments; the technical studies are expected to be completed in early or mid-2015. The environmental document will be available for public review in 2016. Project approval is anticipated by early to mid-2017. Construction would be scheduled to start following project approval, subject to securing funding.

In September 2011, two public scoping meetings were held by the Riverside County Transportation Department (County) to inform the community about the Cajalco Road Widening Project, the County’s intent to prepare an Environmental Impact Report (EIR), and seek input on the proposed project and issues to be addressed in the EIR.

The meetings were held September 26th and September 29th at Lake Mathews Elementary School and Tomas Rivera Middle School, respectively.

The meetings were well attended and valuable information was both shared with and received from the community.

 

Copies of the public meeting notices are also available for download from the “Public Documents” section of this project web site.

As a result of public and agency feedback submitted in response to the NOI and scoping meetings, two additional alternatives are now included for consideration. These alternatives are generally along El Sobrante Road and La Sierra Avenue, north of Alternatives 1 and 2. The four alternatives will be analyzed further in the EIS/EIR, based on a determination that all alternatives appear to meet the purpose and need for the project.

Comments and input from the public and agencies on the project will continue to be welcomed by the County. The County is also seeking to continue to engage the public and agencies in the development and environmental review of the project with local meeting opportunities and through agency coordination. The result of this public and agency input process will be one environmental document that will address the requirements of the California Environmental Quality Act (CEQA) and NEPA, an EIR/EIS that will be produced and available for review and comment.

 

Information on continuing opportunities for input on the project will be provided in several ways:

  • On this website
  • Local newspapers
  • By mail to immediately adjacent property owners and to those who have requested notification
  • To local community groups

 

Inquiries about the Project to the staff noted in the “Project Contacts” section of this project website are welcome.

Project Overview

PROJECT PURPOSE

The purpose of the proposed project is to:

  • Improve the transportation facility to address anticipated growth and mobility needs, as identified in the County of Riverside General Plan Circulation Element Policy 1.5;
  • Provide improved inter-regional travel by improving east-west mobility in Riverside County;
  • Improve roadway alignment and intersection design to enhance safety along Cajalco Road.

PROPOSED PROJECT

The proposed project includes the widening of Cajalco Road between the I-215 southbound ramps and Temescal Canyon Road in the County of Riverside. A small portion of the westernmost part of the alignment is located in the city of Corona. The project would widen the roadway to four lanes between Harvill Avenue and Temescal Canyon Road, and to six lanes between the I-215 southbound ramps and Harvill Avenue, to improve east-west mobility and to provide increased capacity and improved traffic flow and safety. The total length of the project is approximately 16 miles.

Safety enhancements proposed for the project include the following:

  • Construct medians
  • Pave roadway shoulders
  • Improve curves between La Sierra and Temescal Canyon Road
  • Add left and right turn pockets
  • Add roadway signs
  • Provide new and improved traffic signals
  • Install object markers and lighting

Portions of the project are located within the boundaries of the Western Riverside County Multiple Species Habitat Conservation Plan (WRC MSCHP) Stephen’s kangaroo rat (SKR) Long-term Habitat Conservation Plan (HCP), and Metropolitan Water District’s (MWD) Multiple Species Habitat Conservation Plan (MSHCP). The project’s consistency with the plans and goals of the conservation plans will be evaluated in the environmental document that is prepared for the project.

Project alternatives that have been developed and refined based on public and agency input, and preliminary study, are described in the following sections. Four build alternatives with design options are currently proposed to address the project purpose.  A No Project Alternative also is analyzed for the proposed project.

Alternatives 1 and 2 are depicted in the following graphic:

Alternatives 3 and 4 are depicted in the following graphic:

 

Alternative 1

Widen Existing Cajalco Road with Minor Alignment Changes between I-215 and Temescal Canyon Road

Alternative 1 would construct two lanes in each direction (eastbound and westbound) from Harvill Avenue at the east to Temescal Canyon Road at the west, replacing the two-lane roadway that currently exists. Between the I-215 southbound ramps and Harvill Avenue, three lanes would be constructed in each direction (eastbound and westbound), replacing this existing four-lane roadway segment. New striping is proposed along Cajalco Road, between Temescal Canyon Road and Grand Oaks; however, the limit of roadway construction at the west end of the project would end at Temescal Canyon Road. Left turn lanes and right turn pocket lanes are proposed to be constructed along Cajalco Road at selected intersections. The proposed alignment would generally follow the existing roadway and integrate the existing roadway into the proposed new roadbed, resulting in reduced construction costs with some deviations from the existing alignment are proposed for reducing impacts to some existing properties and to improve access.

West of Lake Mathews Drive and north of Lynette Lane, Cajalco Road would be realigned, bypassing the Hollis Lane residential area to the south, and include the construction of a bridge south of Lake Mathews. The new bridge would reduce grading impacts and provide opportunities for improving connectivity between habitat areas. A southern connection between Dirt Road and Lake Mathews Drive is under consideration for secondary access to residences in the Hollis Lane/Lynette Lane area.

Medians of various widths and types are proposed for Cajalco Road to provide for the separation of opposing traffic, provide a recovery area for out of control vehicles, allow space for speed changes and for left- and U-turns, and minimize headlight glare. In rural areas, cross-slopes would be included where appropriate to better conform to the natural terrain, break up the expanse of paving, handle drainage, and serve as potential water quality treatment areas. In habitat areas, the medians would be designed to accommodate small mammal crossings and include the installation of openings to avoid long continuous crossing structures.

Drainage improvements along Cajalco Road will be made and bike lanes considered along segments between Harley John Road and Temescal Canyon Road where the facilities may be accommodated in roadway design.

Alternative 2

Widen Existing Cajalco Road between I-215 and Hollis Lane and between East of Eagle Canyon Road and Temescal Canyon Road; Construct New Segment of Cajalco Road between Hollis Lane and East of Eagle Canyon Road

Between the I-215 southbound ramps and Hollis Lane, the eastern portion of Alternative 2 would be the same as the alignment and changes proposed under Alternative 1. Between Hollis Lane and Eagle Canyon Road, the western portion of the proposed alignment would deviate from the existing roadway, and a new segment of roadway would be established through undeveloped land south of existing Cajalco Road. Specifically, just east of the Hollis Lane intersection with Cajalco Road, the roadway alignment would deviate from the existing alignment, extend west through undeveloped land, and turn north to transition back to join existing Cajalco Road east of Eagle Canyon Road.

From this point to the western terminus at Temescal Canyon Road, the proposed alignment would follow the existing roadway and include the reconstruction of the bridge at Temescal Canyon Wash, as described under Alternative 1.

Medians of various widths and types for Cajalco Road, as described under Alternative 1, would also be proposed under this alternative. Bike lanes are also under consideration for Alternative 2.

Based on community input received during the EIR scoping process, a new, north-south access connection to Cajalco Road is proposed that would extend La Sierra Avenue to the south, beyond its current southern terminus, connecting with the new segment of Cajalco Road. The new southern La Sierra Avenue terminus would occur at an intersection  with the southernmost segment of Cajalco Road, west of Hollis Lane. Cul-de-scas would be added along the existing Cajalco Road just west of La Sierra Avenue, and to the est of Eagle Glen. The southern connection between Dirt Road and Lake Mathews Drive, as described under Alternative 1, would also be considered further under Alternative 2.

Alternative 3

Widen Existing Cajalco Road between I-215 and Gustin Road, Widen and Improve El Sobrante Road between Gustin Road and La Sierra Avenue, and Realign La Sierra Avenue North of Cajalco Road; Construct New Segment of Roadway between Tin Mine Road and Temescal Canyon Road

Between the I-215 southbound ramps and Gustin Road, the eastern portion of Alternative 3 would be the same as the alignment and changes proposed under Alternative 1 and Alternative 2. Between Gustin Road and Temescal Canyon Road, the western portion of the proposed alignment would deviate from the existing Cajalco Road, generally following Sobrante Road north of Lake Mathews. Between Gustin Road and El Sobrante Road, a new segment of roadway would be established through undeveloped land north of existing Cajalco Road, realigning Cajalco Road with El Sobrante Road.

East and north of Lake Mathews, El Sobrante Road would be widened along its existing alignment. The El Sobrante intersection with La Sierra would be improved and La Sierra Avenue slightly realigned to the west to just west of Tin Mine Road, where a new segment of roadway would be established through undeveloped land north of existing Cajalco Road to Temescal Canyon Road.

Medians of various widths and types for Cajalco Road, El Sobrante Road, and the new segment of road between La Sierra Avenue and Temescal Canyon Road as described under Alternative 1, would also be proposed under this alternative.

Alternative 4

Widen Existing Cajalco Road between I-215 and Gustin Road, Widen and Improve El Sobrante Road between Gustin Road and La Sierra Avenue, Realign La Sierra Avenue between El Sobrante Road and Cajalco Road, and Widen Existing Cajalco Road with Minor Alignment Changes between La Sierra Avenue and Temescal Canyon Road

Between the I-215 southbound ramps and Gustin Road, the eastern portion of Alternative 4 would be the same as the alignment and changes proposed under Alternatives 1, 2 and 3. Between Gustin Road and La Sierra Avenue, the mid-portion of the alignment would be the same as the alignment and changes proposed under Alternative 3.

Between La Sierra Avenue and Temescal Canyon Road, the western portion of Alternative 4 would extend south to existing Cajalco Road, and then west along Cajalco Road to Temescal Canyon Road. Between El Sobrante Road and Cajalco Road, La Sierra Avenue would be realigned slightly to the west of the existing La Sierra Avenue alignment. Between the realigned La Sierra Avenue intersection with Cajalco Road and Temescal Canyon Road, the alignment would be the same as the alignment and changes proposed under Alternative 1.

No Project Alternative

Under the No Project Alternative Cajalco Road would remain a two-lane roadway and many of its segments would continue to operate at unacceptable traffic levels similar to existing conditions. Implementation of this alternative would not address regional growth trends expected for this portion of the county. Additionally, current grade deficiencies in the existing roadway would not be addressed or corrected under this alternative.

Cajalco Road between I-215 and Temescal Canyon Road would not be widened or otherwise improved under this alternative. Implementation of this alternative would not improve connectivity between I-215 and I-15 in Riverside County and would not meet project objectives of providing improved speed, capacity, and turning movements to an existing roadway. This alternative would not provide the safety features associated with the proposed project and hence will not improve traffic safety of the existing Cajalco Road.
