Preference Survey (CLOSED June 1, 2017)

The City of Lafayette wishes to gather public feedback on proposed strategies aimed at reducing current and future traffic congestion in and around Downtown Lafayette. A link to our new web-based survey is available below for you and fellow citizens to submit comments on these proposed strategies.

The City conducted the first online survey from mid-November through December 2015. This first survey helped the City and consultant team understand community concerns related to Downtown traffic congestion. It also provided the public with an opportunity to weigh in on traffic-related priorities and to provide direct feedback on specific traffic-related issues through a Collaborative Map.

This first survey had 857 participants and led to the development of over 50 transportation strategies. For the complete Long List, click here.

Since then, City staff and the consultant team have been working with the Plan’s Steering Committee to refine the Long List into a Short List of the most promising 15 strategies. More information about this process, including reports, presentations, and technical studies, are available at the study’s information page and the City’s website.

A map of the 15 Short List strategies is presented below. Use the map to familiarize yourself to the type and location of each strategy.

  • Note the +/- buttons in the bottom left corner of the map to zoom in or out for better usability.
  • Click on an individual “Strategy Icon” or “Colored Road” on the map to reveal more information about it.
  • Click on the [ ] button in the upper right-hand corner of the map to view a larger map version in a separate browser tab.

Following the map is a table summarizing the strategies and pros/cons of each.



Most of the strategies are complementary and can be “mixed and matched” together to form a package of improvements. Two direct conflicts include:

  1. School St One-Way Westbound is in direct conflict with the Brook St-School St Intersection Realignment. It is possible to implement the School Street One-Way strategy in the near-term, remove it, and then implement the Brook St-School St strategy. The School St strategy does not preclude the City from implementing the Brook St-School St strategy later.
  2. The Mount Diablo Blvd / Moraga Rd 2nd Northbound Right-Turn strategy is not required if the City implements the Moraga Rd Extension to 1st St/State Route 24 strategy because both projects address the same issue (northbound capacity on Moraga Rd). Similar to the previous point, the 2nd northbound right-turn could be implemented first and then removed later if the Moraga Rd Extension is constructed.

The survey can be found after the table.

Strategy Pros Cons
1. Coordinated Traffic Signals

Coordinate traffic signals on Mount Diablo Blvd and Moraga Rd Provide advanced traffic signal management to make traffic signals more responsive to changes in traffic flow, incidents, and signal outages.

Cost: $1 – 1.5M

Would reduce traffic congestion by synchronizing signal timings and allowing for better monitoring of traffic conditions. Can promote speeding during off-peak times.
2. School St One-Way Westbound

Convert the travel lanes on School St, between 1st St and Moraga Rd, to one-way westbound traffic.

Cost: $100 – 200k

Reduces congestion on Moraga Rd. by simplifying the traffic signal timing at the Moraga Rd/School St intersection. Diverts approximately 100 vehicles into residential neighborhoods during the highest demand (peak) hour.
3. Mount Diablo Blvd/Moraga Rd 2nd Northbound Right-Turn

Provide a second northbound right-turn from the middle lane at the Moraga Rd/Mt Diablo Blvd intersection.

Cost: $100 – 200k

Reduces congestion on Moraga Rd by allowing more vehicles to turn right at the Moraga Rd/Mt Diablo Blvd intersection. Requires the removal of the north-south crosswalk on the eastern leg of the intersection to eliminate conflicts with pedestrians.
4. Moraga Rd/Moraga Blvd Southbound Left-Turn Lane

Provide a left-turn lane on Moraga Rd at the southbound approach of the Moraga Rd/Moraga Blvd intersection, while maintaining the existing two southbound and northbound travel lanes.

Cost: $50 – 75k

Provides a dedicated turn lane for left turning vehicles to line up at Moraga Rd/Moraga Blvd, which reduces congestion by preventing turning vehicles from blocking the through traffic on Moraga Rd. Removes 6-7 on-street parking spaces on the west side of Moraga Rd.
5. Brook St-School St Intersection Realignment

Combine the existing Brook and School Street intersections with Moraga Rd into a single intersection at Moraga Road and include a new southbound left-turn pocket, to turn onto School St in the direction of Stanley Middle School.

Cost: $3 – 4M

The time it takes to travel on Moraga Rd between Mt Diablo Blvd and St Mary’s Rd would improve by 1 minute (approximately a 10-15% improvement in travel time). Requires demolition of the Masonic Lodge, located at the corner of Brook St. and Moraga Rd.
6. Signalize Deer Hill Rd/Oak Hill Rd and Deer Hill Rd/Happy Valley Rd

Install new traffic signals on Deer Hill Rd at intersections with Happy Valley Rd and Oak Hill Rd.

Cost: $500 – 750k

Would improve traffic flow during peak times and provide greater pedestrian safety with controlled crossings. Traffic signals can result in an increase in rear-end collisions.
7. Moraga Rd Extension to SR 24 Behind McCaulou’s/Whole Foods

Extend Moraga Rd north of Mt. Diablo Blvd, through the Safeway/McCaulou’s shopping complex, to connect with 1st St and the Highway 24 on-ramp (headed eastbound). The roadway section through the shopping complex would operate one-way northbound only.

Cost: $20 – 30M

Reduces congestion by allowing 400 additional vehicles per hour to travel northbound on Moraga Rd. This provides a direct connection to the Highway 24 on-ramp (eastbound). Would likely impact the EBMUD aqueduct and requires redevelopment of the Safeway/McCaulou’s shopping complex to accommodate the connector roadway segment.
8. Additional School Pick-up & Drop-off Zones

Introduce two dedicated areas for student drop-offs and pick-ups: 1) at Golden Gate Way/1st St and 2) at St Mary’s Rd, adjacent to the Stanley Middle School play field.

Cost: $200 – 400k

Formalizes school drop- off and pick-up locations near Downtown school campuses. This would divert traffic from – and reduce traffic volumes on – Moraga Rd by up to 200 trips (equal to 10% reduction) during school drop-off/pick-up times. Would reduce the size of the Middle School fields.
9. School Street Bike-Ped Pathway Connection to Trail

Construct wider sidewalks and a bike lane on the north side of School St, the Lafayette-Moraga Regional Trail to Moraga Rd.

Cost: $500k – 1.0M

Improves the pathways by widening and removing utility obstacles for pedestrians, cyclists, and school children to travel safely independently between the Regional Trail and Moraga Rd. Removes 9 on-street parking spaces.
10. Mount Diablo Boulevard Bike-Ped Pathway Expansion

Implement a “road diet” by removing one eastbound travel lane and converting the space to enhanced bicycle and pedestrian facilities between Acalanes Road and Risa Road.

Cost: $1 – 2M

Improves pedestrian and cyclist access west of Downtown with only a minimal impact on vehicular traffic. Could slow emergency response times in the eastbound direction into Lafayette.
11. Regional Trail Connection to BART/Downtown

Improve bicycle and pedestrian pathways and signage between the Lafayette-Moraga Regional Trail, Downtown, and BART station.

Cost: $50 – 100k

Better signage would improve wayfinding and walking and biking safety. Targeted pedestrian and bicycle improvements would promote walking and cycling in the Downtown. Brook St and other streets located west of Moraga Rd are relatively narrow with limited space for wider biking and walking facilities.
12. BART Pedestrian Bridge over Oak Hill Rd

Construct a pedestrian bridge over Oak Hill Road that connects the BART parking lots east of Oak Hill Rd. with the BART station.

Cost: $6 – 8M

Reduces the walking time by one minute (a 15% reduction) for BART patrons parking in lots east of Oak Hill Rd by providing a direct path to the station without having to cross Oak Hill Rd. This direct path would span over Oak Hill Rd on the north side of, and near to, Highway 24. Constructing this bridge could also eliminate the need for a new traffic signal the Deer Hill Rd/Oak Hill Rd intersection as patrons could avoid the street crossing at that location. Could conflict with the freeway bridge carrying Highway 24 over Oak Hill Rd.
13. Student Pedestrian Safe Routes

Designate safe walking paths to Downtown schools on First St and School St and create a new formal pathway along the eastern edge of the Stanley Middle School fields that connects to the proposed drop-off/pick-up area St Mary’s Rd drop-off area (see Two Additional School Drop-off and Pick-up zones strategy above).

Cost: less than $100k

Provides designated pathways for school children to walk from the additional drop-off and pick-up areas near the Downtown schools. These pathways will encourage the use of the proposed drop-off zones by parents. Requires minor physical improvements and would take some space from the eastern edge of the Middle School fields to create the
14. Enhanced School Bus Program

Add four school buses to serve more Middle School riders and also introduce new service to Lafayette Elementary.

Cost: $320k (annually)

Higher school bus ridership would reduce school-related traffic on Moraga Rd by 120 trips (6%) during school drop-off/pick-up times. Would require some minor bus stop improvements at the Downtown schools and in the residential neighborhoods.
15. Staggered School Times

Shift the start time for Stanley Middle School to 9 AM. Note: the School District has taken no formal position on the school strategies.

Cost: unknown

Reduces overlap of commute and school-related traffic on Moraga Rd. during the morning peak hour commute. Approximately 500 school-related trips could shift to a later hour by having Middle School start at 9 AM. Could result in additional vehicle trips for parents who choose to drive students to both schools at different times. Would not provide a benefit in the evening commute periods. Would also require collaboration with the school district.
