FINANCIAL IMPACT
Approval of this item will not result in the use of Discretionary General Funding (Net County Cost). The estimated cost of $1,000 to install the appropriate signs, as well as minor administrative costs to update the Department of Public Works (Department) records, will be financed by Gas Tax revenue. Sufficient appropriation and revenue are included in the Department’s 2024-25 Road Operations budget (6650002000).
BACKGROUND INFORMATION
Easton Street is a two-lane collector street with one lane in each direction. The City of Rialto maintains the sections west of Ayala Drive and east of Lilac Avenue, both of which have posted speed limits of 35 mph. However, the segment from 68 feet west of Brampton Avenue to Lilac Avenue, maintained by San Bernardino County, currently lacks an established speed limit.
The Department conducted an Engineering and Traffic Survey (E&TS) in June 2024 in accordance with the guidelines outlined in the California Vehicle Code (CVC), Section 627 and the California Manual of Uniform Traffic Control Devices (CAMUTCD), Section 2B.13. These guidelines require speed limits to be based on the speed at which 85% of the public is driving at or below (also referred to as “the 85th percentile”), unless there are conditions present that are not readily apparent to the driver that warrant adjustments.
The E&TS determined the 85th percentile speed to be 38 miles per hour (mph). Based on the CAMUTCD guidance, setting a speed limit of 35-mph is considered reasonable, appropriate, and prudent. At the time of the E&TS there was no established speed limit from 68 feet west of Brampton Avenue easterly to Lilac Avenue.
Establishing a 35-mph speed limit aligns with existing speed limits both east and west of the proposed segment within the City of Rialto. The proposed speed limit would promote uniformity between City and County jurisdictions and assist law enforcement to manage speeding concerns.
To enhance traffic safety and consistency, and findings and determination of the E&TS, the Department recommends establishing a 35-mph speed zone on Easton Street from 68 feet west of Brampton Avenue easterly to Lilac Avenue, pursuant to County Code Section 52.0123(b) and CVC 22358.
This item aligns with the County and the Chief Executive Officer’s goals and objectives to provide for the safety of the traveling public by establishing a speed limit on this stretch of roadway.
PROCUREMENT
Not applicable.
