RECOMMENDATION: Adopt Resolution to Approve Modifications to Spartan Way Design, Change Order No. 2 with United
Pavement Maintenance, Inc. and Budget Amendment
for CIP PS 26-0, Spartan Way Traffic Safety
Enhancements
SUMMARY:
On October 13, 2025, the City Council approved the creation of Capital Improvement Project ( CIP) PS 26-0, Spartan Way Traffic Safety Enhancements, for the installation of a raised crosswalk, median fencing, restriping, and bike lane barriers, with the goal of reducing vehicle speeds and increasing pedestrian safety. On January 12, 2026, the City Council approved a construction contract with United Pavement Maintenance, Inc. for the installation of the raised crosswalk, restriping, and bike lane barriers Project). Work began on March 13, 2026, and the Project was substantially completed on March 23, 2026.
Staff are presenting the option of moving the bike lane barriers 1. 5 feet away from the travel lane line to provide a greater recovery zone for drivers who may drift out of the lane. The modifications may reduce the frequency of collisions and make truck and bus access easier but may result in increased vehicle speeds due to the perceived increase in vehicle lane width.
Staff requests that the City Council review the updated speed data and traffic collision analysis and provide direction regarding potential modifications to the Spartan Way design. If the City Council elects to proceed with the modifications, staff request the City Council approve the City Manager to execute a Change Order with United Pavement Maintenance for $ 40, 832 to move the barriers and a budget amendment of 50, 000 from the Measure C Fund to the Project.

fencing. During the same meeting, the City Council also approved the purchase of the bike lane barriers. On January 12, 2026, the City Council approved a construction contract with United Pavement Maintenance, Inc. for the installation of the raised crosswalk, restriping, and bike lane barriers. Work began on March 13, 2026, and was substantially completed on March 23, 2026.
Staff collected data both before the Project and three weeks after its completion, as shown in Table 1. The Project resulted in a reduction of 8 miles per hour ( mph) in the 85th percentile speed in both directions. The average speeds after the Project are 25 mph eastbound and 29 mph westbound, both of which meet staff' expectations.

The Federal Highway Administration ( FHWA) provides Crash Modification Factors CMFs) to estimate changes in collision rates associated with modifications to roadway geometry and lane width. The CMF for narrowing a travel lane from 11 feet to 9 feet and adding physical barriers on both sides of the lane is 1. 694. The pre -Project collision rate was approximately two collisions per year; therefore, the expected post - Project collision rate is approximately 3.88 collisions per year immediately following the implementation of the modifications.
Although the collision rate is expected to increase immediately after installation, it is anticipated to decrease over time as drivers become familiar with the new configuration. In addition, the type of collisions is expected to change. The Project reduced vehicle speeds; therefore, collisions should be less severe and result in fewer injuries. Prior to the Project, approximately half of reported collisions resulted in minor injuries, whereas the four collisions reported after the Project involved only property damage and no injuries.
Staff are presenting the option of moving the bike lane barriers 1. 5 feet away from the travel lane line to provide a greater recovery zone for drivers who may drift out of the lane. The modifications may reduce the frequency of collisions and make truck and bus access easier but may result in increased vehicle speeds due to the perceived increase in vehicle lane width.
