Speed Hump Installation Request along Neenah Street between Greenwood Avenue and Todd Avenue
BACKGROUND:
The City of Commerce received a resident request to conduct a traffic review and evaluate speed hump installation along Neenah Street between Greenwood Avenue and Todd Avenue to deter vehicles from speeding along the segment.
In response to this request and on behalf of the City, engineering staff completed a traffic review to evaluate if Neenah Street between Greenwood Avenue and Todd Avenue meets the initial criteria for speed hump installation per the City’s Speed Hump Policy. The traffic review included an analysis of the existing roadway conditions, data collection of average daily traffic (ADT) counts, a 24-hour speed survey, a review of 5.5-years of available collision data along the segment, and a review of the City of Commerce Speed Hump Policy criteria.
Neenah Street is considered a Local Road with a posted speed limit of 25mph. Neenah Street is approximately 30-feet wide with one lane in each direction and no marked centerline. Parking along Neenah Street is allowed at all times except during street sweeping. The street sweeping restrictions for the south side are on Tuesdays from 8:00 am to 12:00 pm and the restrictions for the north side are on Wednesdays from 8:00 am to 12:00 pm. According to the City’s Zoning Map, this segment of Neenah Street travels through Single Family Residential zoning.
ANALYSIS:
Traffic Commission Agenda Report
Speed Hump Installation Request along Neenah Street between Greenwood Avenue and Todd Avenue
Average Daily Traffic (ADT): As a part of the traffic study, the Average Daily Traffic (ADT) data was obtained from counts taken on Tuesday, September 24, 2024, for Neenah Street between Greenwood Avenue and Todd Avenue. In order to determine the existing ADT for Neenah Street between Greenwood Avenue and Todd Avenue, counts were taken for eastbound and westbound directions. The ADT for Neenah Avenue in the eastbound direction had 188 vehicle trips over a 24-hour period and the westbound direction had 136 vehicle trips over a 24-hour period for a total ADT volume of 324 vehicles per day along Neenah Street.
Collision Data: A Collision History Analysis was conducted for the subject location. Collision data was obtained from the computerized collision records system maintained by the State of California called the Statewide Integrated Traffic Records Systems (SWITRS). An analysis was conducted of available collisions that were reported to SWITRS of the subject segment of Neenah Street between Greenwood Avenue and Todd Avenue. The collision analysis was conducted over approximately a 5.5-year period between January 2019 through October 2024 (available data at the time of traffic review). Per the Collision History Analysis, there were 0 collisions reported along the segment of Neenah Street between Greenwood Avenue and Todd Avenue within the 5.5-year period.
Speed Survey: To assess the speed at which vehicles are traveling along Neenah Street between Greenwood Avenue and Todd Avenue, a 24-hour speed survey was conducted.
Speed samples were taken over a 24-hour period on Tuesday, September 24, 2024. Based on the Radar Speed Survey, the 85th percentile speed of vehicles surveying traveling along Neenah Street was determined to be 26 MPH, which is above the posted speed limit of 25 MPH. This translates to mean that 85 percent of vehicles samples during the survey were traveling at 26 MPH or below. According to the 24-hour speed survey taken along Neenah Street, 11% of vehicles were traveling at speeds between 25-29 MPH, 5% of vehicles were traveling at speeds between 30-34 MPH, and 2% of vehicles were traveling at speeds between 35-39 MPH, which indicates there was occasional speeding along the segment.
Speed Hump Policy: An analysis of the site and roadway conditions was also evaluated with the criteria of the City of Commerce Speed Hump Policy. The policy states that the Public Works Department may determine which streets are eligible for speed humps based on site and roadway conditions, traffic conditions, and proper engineering principles including, but not limited to, the following:
1. The street must be functionally classified as a residential, local, or collector street. The street cannot be designated as an arterial or higher classification. (This criteria was met.
Neenah Street is classified as a local roadway.)
2. The street should be primarily residential in nature, but streets in commercially or industrially zoned areas can be eligible for speed humps, consistent with engineering Traffic Commission Agenda Report
Speed Hump Installation Request along Neenah Street between Greenwood Avenue and Todd Avenue
analysis and safety concerns. (This criteria was met. Neenah Street is classified as a local roadway and is primarily residential in nature.)
3. The street should not be a truck, transit (bus) route, or emergency service route. (This criteria was met. Neenah Street is not a truck route, transit (bus) route or emergency service route.)
4. The street does not have more than one traffic lane in each direction. (This criteria was met. Neenah Street has one traffic lane in each direction.)
5. The street should have a minimum length of at least 500 feet, preferably 750 feet. (This criteria was met. This street of Neenah Street between Greenwood Avenue and Todd Avenue is approximately 730-feet in length.)
6. The street must have a posted or prima facie speed limit not exceeding 30 miles-perhour. (This criteria was met. The posted speed limit on Neenah Street is 25 MPH.)
7. The street must have a minimum ADT volume of 500 average daily vehicle trips and a maximum ADT volume of 4,000 vehicles per day and with additional assessment of potential impacts on streets with 4,000 to 10,000 average daily vehicle trips. (This criteria was not met. This segment has an ADT volume of 324 vehicles per day.)
8. The street must have adequate drainage and ADA access at street entrances and intersections. (This criteria was met.)
9. The street must have roadway pavement, curbs, gutters, adjoining parkways and sidewalks in good condition. (This criteria was met.)
10.The street cannot have any alignment, grade or sight-distance problems that would be affected or created by speed humps. (This criteria was met.)
11.Speed humps should not be spaced closer than 200 feet when two humps are installed on a single block and should not be spaced closer than 350 feet when three humps are installed on a single block. A speed hump should not be placed within 150 feet of any intersection. A speed hump shall never be installed within any intersection. (This criteria was met. The segment along Neenah Street is long enough to allow for 2 speed humps to be installed.)
12.A speed hump should not be installed if it conflicts or interferes with:
• Drainage features including gutters, channels, drains, catch basins and manholes. • Compliance with NPDES regulations for storm water run-off. • Fire hydrants, water valves, water meters, utility manholes or other utility facilities. • Traffic control devices, including in-pavement signal detector devices. • Driveways, crosswalks, ramps and/or other ADA facilities/regulations. • Bicycle lanes.
• Horizontal or vertical curves in the street alignment or street profile
13.The City will attempt to not place a speed hump within 35 feet of any property edge where the resident of the subject property failed to endorse the petition or had specifically submitted a written objection to the speed hump. If needed, the City will adjust the spacing in between the speed humps accordingly for optimal.
14.The installation and final locations of Speed Humps should be based on the general Traffic Commission Agenda Report
Speed Hump Installation Request along Neenah Street between Greenwood Avenue and Todd Avenue
guidelines in the Commerce Speed Hump Policy as well as Engineering Judgment and field conditions.
Collection of Signatures for Speed Hump Consideration: This criteria was met. The City of Commerce Speed Hump Policy requires signatures of at least 75% of residents fronting the street where the Speed Humps are being requested to demonstrate that they are in favor of Speed Hump installation. The applicant submitted signatures of residents living along Neenah Street between Greenwood Avenue and Todd Avenue. Per the LA County Assessor’s Map, there are a total of 26 units fronting Neenah Street between Greenwood Avenue and Todd Avenue. A minimum of 19 signatures in favor of the speed hump installation would meet the 75% criteria and would be required for the speed humps to be considered for installation.
The applicant obtained a total of 19 signatures, which meets the 75% requirement set by the City of Commerce Speed Hump Policy. This demonstrates that 75% of residents fronting Neenah Street between Greenwood Avenue and Todd Avenue support the installation of Speed Humps.

SPEED HUMP POLICY
The installation of speed humps is intended to provide traffic calming measures to reduce speeding vehicles in residential neighborhoods. Speed humps and other pavement undulations are not approved traffic-control devices as defined in the California Manual on Uniform Traffic Control Devices (CAMUTCD), the official document establishing which roadway devices may be readily installed on public streets.
Instead, a speed hump is considered to be a geometric “design feature” within the roadway that must be designed, installed and maintained based on prudent engineering judgment and supported by a sufficient study of its need. The City of Commerce has an adopted Speed Hump Policy that lists general guidelines of when and where speed humps may be considers for installation.
COMMERCE SPEED HUMP POLICY ANALYSIS
This segment of Neenah Street between Greenwood Avenue and Todd Avenue was analyzed and evaluated with the criteria set forth in the City of Commerce Speed Hump Policy. The policy states that the Public Works Department may determine which streets are eligible for speed humps based on site and roadway conditions, traffic conditions, and proper engineering principles including, but not limited to, the following:
1. The street must be functionally classified as a residential, local, or collector street. The street cannot be designated as an arterial or higher classification. (This criteria was met. Neenah Street is classified as a local roadway.)
2. The street should be primarily residential in nature, but streets in commercially or industrially zoned areas can be eligible for speed humps, consistent with engineering analysis and safety concerns. (This criteria was met. Neenah Street is classified as a local roadway and is primarily residential in nature.)
3. The street should not be a truck, transit (bus) route, or emergency service route. (This criteria was met. Neenah Street is not a truck route, transit (bus) route or emergency service route.)
4. The street does not have more than one traffic lane in each direction. (This criteria was met. Neenah Facing Eastbound along Neenah Street Facing Westbound along Neenah St

Based on the analysis of the ADT, Collison Data, Speed Survey, and City of Commerce Speed Hump Policy criteria, this segment of Neenah Street between Greenwood Avenue and Todd Avenue is eligible for speed hump installation.
RECOMMENDATIONS
After a thorough review of existing field and traffic conditions and per the guidelines in the California Manual on Uniform Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), based on engineering judgement and the City of Commerce Speed Hump Policy, it was determined that this segment meets the criteria for the speed hump installation. Please note that the only criteria that was not met was the ADT criteria for Neenah Street. The segment has an ADT volume of 324 vehicles per day and the Policy states that the street should have a minimum ADT volume of 500 average daily vehicle trips. The ADT traffic being lower than the minimum ADT volume suggested by the Policy, will not have any negative impacts to the speed hump installation.
Please refer to Figure 4: Proposed Recommendations Diagram for a visual representation of the proposed recommendations.
It is recommended that the following items be approved:
Approve the Speed Hump Request along Neenah Street between Greenwood Avenue and Todd Avenue, which includes:
1. Installation of 2 sets of speed humps with reflective triangular markings pointing in the direction of travel along the segment of Neenah Street between Greenwood Avenue and Todd Avenue as shown in the proposed diagram. The exact number and location of the speed humps will be determined during the installation and based on Engineering judgement.
2. Installation of white thermoplastic “HUMP” pavement markings for both directions approaching each set of the speed humps per CAMUTCD Section 3B.26.
3. Installation of 2 “Speed Hump” (W17-1, 30x30) signs for both directions approaching the set of speed humps per CAMUTCD Section 2C.29.
4. Installation of 2 “Speed Humps Ahead” (W84 (CA), 30x30) signs for both directions approaching each set of speed humps per CAMUTCD Section 2C.29.
