CIP 20-29- Approve Plans & Specs-Auth Solicitation to Bid-Brookshire Ave. & Everest St Traffic Safety ProjiteM No. APPROVED BY TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL CITY MANAGER FROM: OFFICE OF THE CITY MANAGER BY: . DIRECTOR OF .2019 APPROVE i SPECIFICATIONS AND AUTHORIZE SOLICITATION PROJECT,FOR BIDS FOR THE BROOKSHIRE AVENUE AT EVEREST STREET TRAFFIC SAFETY ENHANCEMENTS •VEMENT PROJECT NO. 20-29 N Xi COT, 19 1I . • That the City Council approve the plans and specifications and authorize solicitation for construction bids for the Brookshire Avenue at Everest Street Traffic Safety Enhancements Project, Capital Improvement Project No. 20-29. The City received a request to enhance traffic safety at the Brookshire Avenue and Everest Street intersection (see Attachment "A" for location). Staff retained the services of an engineering consultant to evaluate the existing conditions at the intersection to determine what measures, if any, could be implemented at the intersection in order to enhance overall traffic safety at this location. Brookshire Avenue is a four -lane minor arterial with an average daily traffic volume of approximately 12,000 vehicles per day and a posted speed limit of 40 MPH. On -street parking is provided on both sides of Brookshire Avenue in the vicinity of Everest Street and no separate left -turn lanes are provided. Everest Street is a two-lane local residential street with an average daily traffic volume of approximately 700 vehicles per day and a statutory speed limit of 25 MPH. Brookshire Avenue has a mild horizontal curve at its approaches to Everest Street. Brookshire Park is located near the southeast corner of the intersection. In addition, Sussman Middle School is located approximately 750 feet east of the subject intersection on Everest Street at Birchdale Avenue. A marked white "ladder" crosswalk is currently in-place on the south side of the intersection which serves to concentrate pedestrian crossings across Brookshire Avenue at its intersection with Everest Street for persons walking to and from Brookshire Park and school-age children walking to and from Sussman Middle School. Supplementary flashing warning beacons mounted on overhead mast arms (see Attachment "B") along Brookshire Avenue in advance of Everest Street activated by pedestrian detection, warning signs and pavement markings to augment the crosswalk and to heighten motorist awareness of the possible presence of pedestrians are currently in-place at the intersection. The evaluation conducted by the City's consultant at the Brookshire Avenue and Everest Street intersection concluded that overall traffic safety could be enhanced at this location if the existing flashing warning beacons were upgraded with the newer style rectangular rapid flashing CAPITAL IMPROVEMENT PROJECT NO. 20-29 BROOKSHIRE AVENUE AT EVEREST STREET TRAFFIC SAFETY ENHANCEMENTS PROJECT JULY 23, 2019 PAGE 2 beacons (RRFBs)(see Attachment "C"), which flash in a rapid on-off pattern and, hence, are more effective in capturing motorists' attention compared to the traditional flashing beacons currently in-place which flash in a slower on-off pattern. In addition to replacing the existing overhead warning beacons located in advance of the intersection, new RRFBs will also be installed on Brookshire Avenue at Everest Street, facing both northbound and southbound directions, at the southwest and southeast corners of the intersection immediately adjacent to either side of the crosswalk. The existing warning signs will be replaced with new fluorescent yellow -green school crossing warning signs and new yellow school pavement markings will be installed in place of the existing markings. New "yield" condition symbol limit lines and supplementary pavement markings will also be installed on Brookshire Avenue in both directions immediately before the crosswalk to reinforce the need for motorists to yield the right- of-way to pedestrians crossing Brookshire Avenue within the crosswalk. Since Sussman Middle School is located within 2,800 feet of the Brookshire Avenue at Everest Street intersection, there are no intervening yellow school crosswalks between the intersection and the school other than those located immediately contiguous to the school grounds and traffic safety could be further enhanced for children walking to and from the school campus across Brookshire Avenue at Everest Street by installing a yellow "school" vs. a white conventional crosswalk, the new crosswalk and supplementary pavement markings augmenting the crosswalk at the subject intersection will be marked in yellow in accordance with the California Vehicle Code and state guidelines for traffic control devices. F11 • The plan (see Attachment T"), specifications and construction cost estimate have been completed for this project, which is now ready for solicitation of construction bids. In accordance with the measures recommended as a result of the evaluation conducted on the subject intersection, this project will feature the following specific traffic safety enhancements; • Upgrading of the existing flashing warning beacons with a new rapid rectangular flashing beacon (RRFB) system complete, m Replacement of all existing pedestrian crossing warning signs with fluorescent yellow - green school crossing warning signs, • Replacement of existing white "ladder" crosswalk on the south side of the intersection with a yellow school "ladder" crosswalk with yield symbol limit lines and supplementary "SLOW SCHOOL XING" and "WAIT HERE" pavement markings, • Reconstruction of the curb ramps on the southwest and southeast corners, and 0 Installation of LED safety lighting on the southwest corner. Construction of the safety enhancements is anticipated to begin in September 2019 and be completed by October 2019. This project is categorically exempt from the provisions of CEQA under Section 15301(c), Existing Facilities.
