TRAFFIC ENGINEERING DIVISION

MEMORANDUM
DATE: April 27, 2023
TO: Parking and Public Improvements Commission
FROM: Erik Zandvliet, T.E., City Traffic Engineer
SUBJECT: Discussion of Potential Traffic Calming Measures on Valley Drive between 27th Street and Sepulveda Boulevard

RECOMMENDATION
Based on the Traffic Engineer’s analysis, it is recommended that the Commission pass a motion to recommend that the City Council approve the following traffic calming measures, along with strict enforcement of speeding violations on Valley Drive between 27 th Street and Sepulveda Boulevard:

1. Install a speed activated flashing speed limit sign on Valley Drive west of Oak Avenue;

2. Construct a temporary landscaped center median, eastbound left turn pocket and curb extension on Valley Drive between Oak Avenue and Sepulveda Boulevard on a trial basis, to be reviewed at least six months after installation;

3. Initiate a capital project and pursue funding to construct raised crosswalks and bulb-outs on Valley Drive at Walnut Avenue and on Valley Drive at Elm Avenue; and

BACKGROUND
On March 7, 2023, the City Council heard public testimony from residents concerned regarding traffic safety on Valley Drive after a recent collision involving a young bicyclist at the intersection of Valley Drive and Pine Avenue. The City Council directed staff to work with the Parking and Public Improvements Commission ( Commission) to propose possible traffic calming solutions for their future consideration.

On A
pril 17, 2023, the City received a follow-up petition circulated by Chad Felke, and signed by over one hundred local residents asking for stop signs on Valley Drive at Pine Avenue (Exhibit A).

The petitioners express concerns for high volume and speeds on Valley Drive, and additionally request safe crossings to the Veterans Parkway, specifically raised crosswalks and corner bulb outs on Valley Drive at Walnut and Elm Avenues. The petitioners object to the dashed yellow centerline, which allows vehicles to pass a vehicle on the left side if it is stopped in the lane.

Previous Actions
On January 22, 2015, the Commission held a public meeting to discuss a request for stop signs or other traffic measures at the intersection of Valley Drive and Oak Avenue/35 th Street. The Commission discussed the Traffic Engineer’s evaluation supporting stop signs in all directions and temporary realignment of the intersection approaches and heard from several speakers in favor of the stop signs and/or other speed reduction measures. The Commission passed a motion 4 -1 recommending the installation of stop signs in all directions at the intersection of Valley Drive/Oak Avenue/35th Street, including temporary realignment of the south and west approaches on a trial basis.

On March 4, 2015, the City Council considered the Commission’s recommendation, heard public testimony, and directed staff to examine other options at this intersection, especially visibility solutions for southbound Oak Street traffic, and ingress and egress solutions for the Ross Manhattan Terrace senior apartments. The City Council directed staff to return the matter to the Commission for further evaluation.

On April 23, 2015, the Commission held a second public meeting and reviewed additional traffic calming measures that could address the residents’ concerns related to speeding and restricted visibility. After hearing public testimony, the Commission voted 3-0 to recommend the installation of 1) painted crosswalks on the north and west approaches at Oak Avenue and 35th Street, 2) a curb bump-out on Valley Drive near the Ross Manhattan Terrace, 3) a northbound left hand turn lane from Valley Drive to Oak Avenue, 4) a center median from Sepulveda Boulevard to Oak Avenue and 5) a speed awareness sign on Valley Drive at Pine Avenue on a trial basis. On July 7, 2015, the City Council discussed the Commission’s recommendation and voted to install painted crosswalks on the north and west approaches at Oak Avenue and 35 th Street (1) and install a speed
awareness sign on Valley Drive for a minimum 6-month trial basis.

In 2013, the City completed the Veterans Parkway Landscape Master Plan, which recommended pedestrian connections on Valley Drive at Maple Avenue, Pine Avenue and Elm Avenue. The City obtained grant funding and constructed some of the recommended improvements in 2018, but a planned pedestrian path at Pine Avenue was removed from the project due to funding limitations.

There is no current pedestrian path at this location.

The City Council has made pedestrian safety and crossing enhancements a high priority in its overall Work Plan since 2017 , and directed staff to explore vari ous crosswalk enhancement opportunities. On February 4, 2020, the City Council approved a prioritized list of proposed crosswalk enhancements to be included in the City’s Capital Improvements Plan as recommended by the PPIC at its meeting on September 26, 2019, and directed staff to pursue funding opportunities. The list of enhancements was prepared by the Traffic Engineer based the City’s “Pedestrian Crossing Enhancements Policy” strategies and supported the pedestrian oriented goals and policies of the City’s General Plan, Mobility Element, Downtown Specific Plan and various Neighborhood Traffic Management plans . The prioritized list included proposed

crosswalks, signs, corner bulb -outs and curb ramps at Valley Drive/Walnut Avenue and Valley Drive/Elm Avenue.

DISCUSSION
Valley Drive is a 32 feet wide two -lane residential collector street with a 30 mph posted speed limit. It has a slight downslope in the westbound direction between Sepulveda Boulevard and 27th Street. (Exhibit B) Valley Drive is stopped at 27th Street and Sepulveda Boulevard. The southeast side of Valley Drive is along the Veterans Parkway. The Belamar Hotel and Ross Manhattan Terrace senior apartments are located at the east end of Valley Drive. Eastbound Left turns are prohibited on Valley Drive at Sepulveda Boulevard between 6-9 AM and 3-7 PM Monday through Friday. Speed limit signs are posted in both directions, and an electronic speed awareness sign is located on the southeast side of Valley Drive at Pine Avenue. There are white edgelines on both sides of Valley Drive to narrow the appearance of the travel lanes as a traffic calming measure.

Valley Drive is posted as a bike route on the southeast side of the street.

The intersection of Valley Drive and Oak Avenue and 35
th Street is located in a residential area
about 300 feet west of Sepulveda Boulevard. Oak Avenue and 35th Street are 30 to 34 feet wide two-lane local streets with a 25mph prima facie speed limit. There are stop signs on the north leg of Oak Avenue and the west leg of 35th Street at Valley Drive. All streets are improved with curbs, and some sidewalks. Curb parking is allowed on both sides of Oak Avenue and 35 th Street, and on the northwest side of Valley Drive. Curb parking demand is generally light during the day and moderate to heavy at night. There are crosswalks and cross-gutters on the north leg of Oak Avenue and the west leg of 35 th Street at the intersection. Pedestrian visibility is good in all directions.

Field Observations
Field observations were made on typical days during peak and non- peak periods. Field observations confirm higher traffic volumes on Valley Drive and ot her physical characteristics as noted above. Right -of-way is assigned by stop signs on Oak Avenue and 35 th Street, but the configuration is unusual because the opposing approaches are not stopped. This is due to the angled alignment and high traffic volume of Valley Drive, which is designated as a through street at the intersection. Sight distance is fair from of Oak Street and 35th Street, with the exception that the sharp intersecting angle of Valley Drive restricts sight distance for drivers stopped on both streets. Also, drivers exiting a nearby driveway for the senior living complex may have difficulty seeing vehicles approaching from Sepulveda Boulevard. Higher than expected speeds were observed on Valley Drive through the intersection. The Traffic Engineer observed that most motorists on Valley Drive have a low awareness of pedestrians or stopped cars at the intersection.

Valley Drive between 27 th Street and Sepulveda Boulevard is currently posted with a 30 mph speed limit. The latest volume and speed counts were conducted in June and July 2022 respectively. A summary and a comparison to similar counts in 2015 are provided below:

DESCRIPTION 2015 2020

Page 3 of 45 ends

PPIC MTG 04/27/2023

Daily Traffic Volume 5,404 vpd 5,463
50th Percentile Speed 26 mph 30 mph
85th Percentile Speed 37 mph 35 mph

The prevailing speed on Valley Drive is higher than expected for a street with fronting residential homes and for its classification as a residential collector street. This speed can be primarily attributed to the high entering speed of drivers entering Valley Drive from Sepulveda Boulevard, as well as the uninterrupted distance between stop signs on a street segment with homes on one side only.

A vehicle volume count at Valley Drive/Oak Avenue/35
th Street was conducted on October 13,
2014, on a typical school day. A summary of the peak hour and daily volumes are provided below:

The traffic collision history between January 1, 2015 and December 31, 2019 was analyzed for this street segment. According to City records, there have been eight collisions reported on the segment of Valley Drive between 27th Street and Sepulveda Boulevard during this five (5) year period. Four collisions were reported at Valley Drive/Oak Avenue involving eastbound left turning traffic, and four collisions were reported involving drivers hitting parked cars or other objects.

There were two notable collisions on this street segment that since 2020: one collision in 2022 involved an eastbound left turning driver who failed to yield to a westbound driver at Oak Avenue, and the aforementioned collision in 2023 involving a bicyclist who was sideswiped by an eastbound driver.

Potential Traffic Calming Measures
The City Traffic Engineer has analyzed several traffic measures that could address limited intersection sight distance, speeding on Valley Drive, collisions or all three. The City’s Pedestrian Crossing Enhancement policy was also used to evaluate potential crossing treatments for Veterans Parkway access. An evaluation of these measures is summarized below:

PPIC MTG 04/27/2023

The State of California has established guidelines for the installation of stop signs. These criteria have been widely accepted and are used by the City of Manhattan Beach. Multi-way or all-way stop controls are generally recommended when one or more of the State criteria are satisfied and indicate the existing traffic control devices are not sufficient to assign proper right-of-way or cannot be remedied through other means. Two locati ons have been evaluated for multi-way stop signs as detailed in Exhibit C and summarized below:

1. Valley Drive/Oak Avenue/35th Street Stop Signs
A stop sign warrant checklist was completed that indicates that multi- way stop signs are warranted at this intersection. This intersection has sufficient right-of-way controls with two-way stop signs, but does not meet minimum minor street volumes and does not meet the minimum warrant for recurring collisions. However, restricted sight distance of approaching vehicles on both Oak Avenue and 35 th Street and a higher than expected approach speed on Valley Drive are special conditions that justify stop signs in all directions. There is a concern that a stop sign on the westbound approach of Valley Drive would cause significant queuing, which could impede traffic at Sepulveda Boulevard. Additional stop signs may also increase the potential for cut through traffic on adjacent streets.

2. Valley Drive at Pine Avenue Stop Signs
A stop sign warrant checklist was completed that indicates that multi- way stop signs are NOT warranted at this intersection. This intersection has sufficient right -of-way controls with a stop sign on Pine Avenue, but does not meet minimum minor street volumes and does not have a recurring collision history. However, the sight distance for drivers waiting at the stop sign on Pine Avenue is somewhat restricted, which can be improved by trimming the landscaping on the northeast corner. A stop sign at Pine Avenue might also have the unintended result of diverting some current Valley Drive traffic onto Pine Avenue.

Valley Drive/Oak Avenue/35th Traffic Calming
There are several ways to modify or realign Valley Drive west of Sepulveda Boulevard into a more conventional intersection geometry to discourage speeding and the potential for traffic collisions. Several concepts were considered by the Commission and City Council in 2015, including a south and east leg realignment, mini-traffic circle, splitter island, road narrowing, 3-way stop sign, or landscaped center island with a left turn lane. Of the concepts presented, the Traffic Engineer believes a landscaped center median, left turn pocket and curb extension between Oak Avenue and Sepulveda Boulevard would achieve the desired traffic calming in both directions, without potentially diverting extra traffic onto 35 th Street or creating a long
queue of stopped vehicles. It would also reduce the potential for collisions by improving sight distance for drivers exiting the senior apartments and providing a separate lane for left turning traffic onto Oak Avenue. This concept is shown in Exhibit D.

Raised Crosswalks a
nd Curb Bulb-outs.

Page 5 of 45 ends

PPIC MTG 04/27/2023

Raised crosswalks and curb bulb- outs can be an effective traffic calming device when carefully designed and installed. R aised pavements generally reduce vehicle approach speed to 24 -28 miles per hour , similar to a speed hump. It highlights the location of the crossing, especially if they are constructed with decorative pavement materials. However, raised crosswalks may incrementally slow down emergency response times depending on the design speed of th e raised crosswalk. Curb bulb-outs reduce the crossing distance and improve the ability for drivers to see pedestrians waiting to cross. They also reduce the apparent width of the street, further discouraging speeding. New crosswalks and bulb-outs on Valley Drive at Walnut Avenue and Elm Avenue were identified in the City’s crosswalk enhancement study. As an interim measure, painted crosswalks and curb bulb -outs may be constructed at both intersections to determine if speed reductions are achieved before considering raised crosswalks (Exhibits E and F) . It should be noted that curb ramps are required with any crosswalk installation to provide and accessible path across the street.

Electronic Speed Awareness Sign
There is an existing electronic speed awareness sign on Valley Drive at Pine Avenue, which is periodically rotated to face opposite directions. A solar-powered speed activated flashing speed limit sign could be installed on Valley Drive just west of Oak Avenue that would start flashing if drivers are exceeding the posted speed limit. This sign is effective because it is only activated if the driver is speeding. This measure could be implemented separately or in combination with other measures.

Double Yellow Centerline
Valley Drive is currently striped with a dashed yellow centerline between 27th Street and Oak Avenue. Engineering studies have not found that the type of centerline striping significantly changes driver behavior. The purpose of a double yellow centerline is to make passing on the left side of the centerline illegal, such as where sight distance is limited in a curve or over a hill. It should be noted that left turns are allowed over a double yellow centerline. On Valley Drive, a double yellow centerline would make passing a stopped vehicle illegal, (i.e. passing a stopped trash truck or delivery van).

CONCLUSION
The City Traffic Engineer also considered other intersection measures, such as a three -way stop (add a northbound Valley Drive stop sign), intersection chokers a nd turn restrictions, but these would not fully address sight distance restrictions and speeding issues. The City Traffic Engineer finds that the combination of a landscaped center median and curb extension on Valley Drive between Oak Avenue be implemented, because this measure would address speeding and sight visibility issues, and provide clearer lane control at Oak Avenue. In addition, a speed activated flashing speed limit sign is recommended for eastbound traffic just west of Oak Avenue to target speeders entering the neighborhood. It is recommended that any roadway realignment be tested on a trial basis with striping and delineators. A follow -up study would be conducted and presented to the Commission after six months to evaluate its e ffectiveness, before considering a

Page 6 of 45 ends

PPIC MTG 04/27/2023

permanent realignment. The evaluation would include before -after traffic counts, speed study, collision data and public feedback to determine if the measures reduced speeds, improved visibility and discouraged neighborhood intrusion. Speeding can and should be strongly enforced on Valley Drive, now that the speed surveys have been updated and radar/lidar enforcement is defensible in court.

PUBLIC NOTIFICATION , OUTREACH, AND COMMENT
Residents on this street segment and all petitioners were notified by mail of this agenda item and were invited to give input to the Commission. The public has been informed of this agenda item as part of the City’s standard meeting notice practices via public bulletin boards, website calendar, and social media. The City has received no additional correspondence related to this matter prior to posting the agenda for this item.

N Valley Drive Neighborhood Traffic Management Program
TO:

Manhattan Beach City Council Members: Mayor Montgomery, Mayor Pro Term Franklin, Councilmembers: Howorth, Lesser and Napolitano.

Planning Manager-Tatyn Mirzakhanian
Traffic Engineer- Erik Zandvliet
City Manager- Bruce Moe
MB Public Works Dept
The City of Manhattan Beach is recognized for providing outstanding municipal services for California's safest Beach Community so please accept this urgent request and petition of support to address the need for:
• Installing a stop sign at North Valley Drive and Pine Avenue Our residents are hoping that this petition makes our neighborhood safer for all the families, children, elderly and disabled people that live nearby. North Valley Or residents and our neighbors on side streets (27th, Poinsettia, Walnut, Pine, Elm &35th) have long endured very dangerous traffic conditions on this part of the tree section. This stretch of Valley Dr is almost 1/2 mile long, which is the longest residential street in MB without a stop sign. The high volume of daily traffic + the high rate of speed which constantly exists+ distracted drivers is the recipe for disaster...we also do not agree with having passing lanes which encourages drivers to pass other cars, which we see on a daily basis. In addition to frequent accidents and collisions on this street, recently a 6th grade boy in the bike lane was hit by a car at the Valley & Pine location.

In addition to not having a stop sign for almost 1/2 mile on N Valley Dr, we also do not have one crosswalk to safely access Veterans Parkway. If someone wanted to walk on to the Veterans Parkway, they would have cross into oncoming traffic with vehicles driving at very high rates of speed. The City of MB just completed the Sepulveda bridge widening/tunnel improvement project connecting Veterans Parkway to the MB Village mall, but ironically our residents cannot safely access Veterans Parkway to use the tunnel.

Therefore, we are also asking your support to address the need for:

Installing raised crosswalks with bulb outs and flashing beacons at N alley Dr & Walnut Ave.

Installing raised crosswalks with bulb outs and flashing beacons at N Valley Dr and Elm Ave.

We urge you to make our safety your priority. Please make this N Valley Dr Neighborhood Traffic Management Program part of Plan Zero in order to eliminate any further traffic related accidents with pedestrians/bicyctists. In 2018 we had a Capital Improvement Plan to address these concerns but it never came to fruition. Please make our neighborhood safe for everyone to enjoy without fear of injury/death from speeding vehicles as well as safe access to Veterans Parkway.

Sincerely,
N Valley Residents & Neighbors

E STREET STOP SIGN WARRANTS
 On a less important road where the normal right-of-way rules would not be expected to provide reasonable compliance with the law.
 On a street entering a legally established through highway or street.  At an unsignalized intersection in a signalized area.  At other intersections where high speeds, restricted view, or crash record indicates a need for control by a stop sign.

MULTI-WAY STOP SIGN WARRANTS
 Where traffic signals are warranted, and stop signs are used as an interim measure to control traffic while the signal is installed.
 Where a crash problem exists, as indicated by five or more reported accidents within a 12 month period of a type correctable by a multi-way stop sign.
 Where the total vehicular volume entering from the major street approaches average at least 300 vehicles per hour for any 8 hours, and the combined vehicular, bicycle and pedestrian volume from the minor street approaches average at least 200 units per hour for the same 8 hours, with an average delay to the minor street traffic is at least 30 seconds per vehicle during the highest hour, and if the 85
th percentile approach speed of the major street traffic exceeds 40 MPH, the minimum vehicular volume warrant is 70 percent of the above requirements.  Where there four or more reported accidents within a 12 month period of a type correctable by a multi-way stop sign, and the average major and minor street volumes are at least 80% of the minimum values.
 Other locations where multi-way stop signs are justified based on an engineering study.
