Project Location: The proposed Project, County Line Road Transportation Corridor, is located along the Riverside and San Bernardino County line in the Cities of Calimesa and Yucaipa (Cities) within the southerly border of the City of Yucaipa and the northerly border of the City of Calimesa. The City of Calimesa covers approximately 23.2 square miles within the County of Riverside which is bordered by the City of Beaumont to the west, Morongo Band of Mission Indians to the east and County of Riverside to the south and County of San Bernardino to the north. Specifically, the proposed linear Project is located on County Line Road from Park Avenue to Bryant Street as depicted on the U.S. Geological Survey (USGS) YUCAIPA, TRS is T02S, R02W, Sect 11, 12, 13, and 14, and T02S R01W Sect. 7 and 18.

Project Sponsor: The Cities of Yucaipa and Calimesa

Project Description

The Project Applicants, the City of Calimesa and the City of Yucaipa, submitted a grant application for the Local Partnership Program (LPP). The LPP grant is for construction of a roadway corridor, drainage, and related improvements on County Line Road from Park Avenue to Bryant Street consistent with LPP Eligible Project, subsection D guidelines. The County Line Road Transportation Corridor Project (Project) includes the improvement of approximately 4,942 linear feet (LF) along County Line Road and 2,142 LF on the cross streets for a total length of 7,084 LF. The Project boundary goes between the Counties of Riverside (to the south) and San Bernardino (to the north).

The Project is a multi-modal surface transportation enhancement project, which addresses traffic congestion and safety coupled with facilitation of growth and non-motorized transportation systems. The existing County Line Road corridor does not have sufficient capacity to serve the current traffic volumes and utilizes multi-way stop control at every intersection, thus resulting in a Level of Service (LOS) below D, approaching unstable flow. The Project proposes to construct four (4) single-lane and one (1) multi-lane roundabouts, together with street, pedestrian, and bicycle improvements, to improve safety and efficiency throughout the corridor. The use of roundabouts, in lieu of signalized intersections, provides adequate capacity and LOS for County Line Road to remain a two-lane street, thus significantly reducing right-of-way and construction costs to construct a four-lane corridor. Roundabouts will be constructed at the intersections of 5th Street, 3rd Street, 2nd Street, California Street, and Bryant Street. In addition, street improvements will be implemented between Park Avenue and 5th Street, 5th Street East (Mid-Block) to 3rd Street, and California Street to Bryant Street. The Project proposes to acquire approximately 1.3 acres of property. The acquisition is proposed for public right-of-way that includes roadway, drainage, gutter, and/or sidewalk features.

The Project will be constructed in one phase and is expected to take approximately four months, and being balanced on site, starting no sooner than fall 2019.
