How Our Plan

Gets Us There

Transportation policy choices are key to achieving the equity, environment, and quality-of-life outcomes discussed throughout the General Plan. Currently, South San Francisco residents and employees have few convenient choices to travel without a car: approximately 90 percent of all trips by residents and over 80 percent of commute trips by employees occur via driving. The auto-centric nature of the city’s transportation system generates traffic congestion, greenhouse gas emissions, and inequitable access to jobs and services.

South San Francisco relies on transportation infrastructure that was built for a different era when life was lived closer to home and the city had more heavy industry and fewer people and jobs. Today’s reality is more regional in nature, spanning commutes between employment centers, goods movement, and travel to retail, medical, hospitality, and recreational facilities. Freeways are fully built out, yet traffic congestion continues to worsen. With the Bay Area expected to add another 1.5 million people in the next two decades, cleaner, less space-intensive forms of travel will be necessary to keep the region and South San Francisco moving. South San Francisco is well-positioned to capitalize on this shift, with access to two BART stations, a new Caltrain station expected to see a substantial increase in service, a ferry terminal serving regional commuters, and a local network of buses, shuttles, and bikeways. Nonetheless, further modernization of the city’s infrastructure is needed.

Health and safety are inextricably linked to the transportation system. Roadway collisions are the leading cause of death for people under the age of 55, and more than half of all road traffic deaths occur among vulnerable road users — pedestrians, bicyclists, and motorcyclists. For South San Francisco to achieve Vision Zero – eliminating all injury collisions on roadways – requires making tradeoffs to prioritize safety, such as reducing vehicle speed limits on local streets or allotting more street space to vulnerable users in the form of bikeways and sidewalks.

Transportation policy offers an opportunity to deliver mobility in a more equitable manner. On average, transportation is the second-largest cost for households, and the cost is largely driven by the location of one’s home in relation to jobs and services. Because housing is costly in San Mateo County, is it often the case that people earning less make the longest, most expensive commutes. Providing more housing close to job centers and prioritizing improvements for the city’s most vulnerable communities represent key strategies for realizing a more equitable mobility system.

and Opportunities

Modernizing the Transportation System
for a Growing City

As South San Francisco continues to experience growth and change, its transportation needs are increasingly mismatched with the infrastructure and services constructed years ago to support “the Industrial City.” This mismatch is especially apparent in the East of 101, Lindenville, and the El Camino Real sub-areas, where large auto-oriented streets are increasingly at-odds with higher density developments more oriented toward walking, biking, and transit use. In many areas of the city, residents and employees rely on driving for the vast majority of trips because there are few other viable options.

As the local and regional population grows the number of trips will also increase. Roadways cannot be expanded to accommodate a similar increase in vehicle trips and more trips must be made by non-auto modes. Local trips within South San Francisco should be made by walk, bike, scooter, and transit whenever possible.

Modernizing South San Francisco’s transportation system means giving people choices in how they travel within the city and region. It also means right-sizing the city’s transportation infrastructure, adding new streets and trail connections, and phasing out vestiges of the past like the city’s freight rail spurs. By building a more multimodal transportation network, South San Francisco can achieve a safe, multimodal, sustainable, livable, and connected city.

Capitalizing on Regional Transit Improvements to Realize Mode Shift

South San Francisco is uniquely positioned to capitalize on several regional transportation improvements that can help reshape travel patterns for residents and employees. These projects include planned service expansions by Caltrain, SamTrans, and San Francisco Bay Area Water Emergency Transportation Authority (WETA), along with the new Caltrain station providing a more direct connection to Downtown and the East of 101 sub-area. These changes present opportunities to reduce vehicle miles traveled and shift vehicle trips (especially longer distance commute trips) to transit.

In order to realize the full potential of these projects, South San Francisco will need to prioritize walkable station areas along with first/last mile improvements that connect residents and employers with regional transit via shuttles and active transportation facilities. Such improvements are particularly critical for the East of 101 and Lindenville areas, where it is important for buses and shuttles to provide fast, direct, and reliable connections separated from traffic congestion and delays.

Connecting the City
for Multimodal Travel

South San Francisco’s fragmented street grid presents challenges in accommodating growth. These challenges are especially apparent at the gateways to the East of 101 sub-area, which has constrained access via just four streets providing east-west and north-south connections. Other sub-areas experience limited connectivity as well: just four streets provide east-west connections between El Camino Real and Downtown/Sunshine Gardens, and much of Lindenville remains relatively isolated from adjacent areas. Traffic congestion tends to be concentrated on the few streets connecting the city given the lack of alternatives, and constrained right-of-way can limit opportunities for bicycle, pedestrian, and transit improvements.

East-West Connections

South San Francisco is not equally accessible by all modes of travel. For example, from El Camino Real at the South San Francisco BART station, only by traveling in a car can you reach all of the East of 101 area within 30-minutes. North-south connectivity is far superior to east-west connectivity and the East of 101 sub-area – the biggest cluster of jobs in the city – is virtually inaccessible to local bicycle and transit travelers coming from the western neighborhoods including parts of Sunshine Gardens, Serra Highlands, Westborough, and Avalon. Although regional transit travelers can use the San Bruno BART station for closer access to East of 101 jobs, local South San Francisco residents on the west side are disconnected from jobs and other opportunities on the east side. Improving accessibility for transit and active transportation modes (especially east-west access) represents a key opportunity for the city’s transportation system.

Travel Sheds

Focus on Safety

With hundreds of miles of roadway and trails, it can be difficult to focus the City’s energy and financial resources. The desired General Plan transportation outcome is a system that is safe, connected, multimodal, sustainable, and livable. Safety is foundational for the other outcomes. Residents and employees will only choose to bike, walk, and take transit if they feel safe doing so and mode shift will only occur if the city proactively undertakes projects to protect these most vulnerable roadway users. The ability to use these alternatives to get around the city will greatly improve health and environmental outcomes, which when combined, work to improve sustainability and livability.

The priority network provides a roadmap to improve multimodal safety projects in South Francisco in coordination with the City’s Local Road Safety Plan and Active South City Plan. The priority layers include:

High-injury network: The high-injury network is the subsection of streets in South San Francisco where 75% of injury collisions occurred between 2015 and 2019, with greater weighting for collision that resulted in a severe injury or death. The vast majority of collisions are predicted to occur along these same streets in the future unless safety countermeasures are enacted.
Complete streets opportunities: Complete streets opportunities represent streets that are not currently part of the high injury network but are expected to play an outsized role in serving the changing context in the city. While a pattern of injury collisions has not yet been observed, these corridors may present a higher risk as land use and transportation changes occur.
School and community zones: School and community zones highlight the importance of pedestrian and bicycle safety for all ages and abilities within one to two blocks of schools and community centers.
Regional transit zones: Areas within ½ mile of BART, Caltrain, and the ferry are priorities for pedestrian and bicycle safety to support access to regional transit and ridership growth. Referred to as transit-oriented communities in the Land Use Element.

Street Network

In order to accommodate anticipated growth, the city’s street network will need to evolve in the coming decades. Streets in South San Francisco are categorized into five typologies: Boulevards, Connectors, Downtown Main Streets, Industrial, and Neighborhood Streets.

Boulevard

Boulevards (arterials) serve as primary routes to destinations within the city or through the city. These roadways are designed to prioritize mobility and person throughput for all types of road users. They can accommodate larger volumes of travelers. They typically have four to six travel lanes (both directions combined), larger sidewalks, and dedicated bicycle facilities. They may also include dedicated facilities for buses. Where the right-of-way is limited, user safety and person throughput (via vehicle, transit, bicycle, and foot) should be prioritized vehicle delay or parking.

Connectors and Downtown Main Streets

Connectors (collectors) are primary or secondary streets within the city that serve as corridors to major destinations. These streets are designed to provide mobility space for all travelers – vehicles, pedestrians, bicyclists, and transit riders. They also provide access to major destinations and denser residential or commercial areas and can accommodate moderate volumes of travelers. Connectors generally have two travel lanes, sometimes with short four lane segments or a center left turn lane. Connectors have sidewalks and provide on-street bicycle facilities and/or on-street parking.

Downtown streets are a special type of connector where mobility related to higher density commercial and housing converge into a single corridor in which people do business, live, and interact with each other. Downtown streets typically serve as destination corridors rather than through routes, with lower traffic speeds, higher pedestrian and bicycle volumes, and flexible use of curb space for high-turnover on-street parking, loading, bicycle parking, and parklets. These streets typically have narrower two-lane cross sections. Design is focused on providing a vibrant walkable setting conducive to local business activity.

Neighborhood and Industrial Streets

Neighborhood (local) streets are primarily located in residential neighborhoods. These streets provide local access to and between residential areas, commercial areas, schools, parks, and community centers. These streets typically have two travel lanes and on-street parking if street widths permit. They may incorporate design features to calm or discourage use by vehicles and prioritize their use as bicycle boulevards or slow streets.

Industrial streets are like neighborhood streets but are designed to serve the needs of manufacturing and goods movement businesses that need access by larger and heavier vehicles. Common vehicles often include vans, single unit trucks, and smaller semi-trucks. Industrial streets may have two vehicle lanes, and occasionally wider lane widths to accommodate larger vehicles. Industrial streets should have speed limits no greater than 25 mph.

Transit Priority Corridors

Some streets in South San Francisco warrant special consideration as transit priority corridors – corridors that serve high frequency bus and shuttle routes under existing or future conditions. Transit priority corridors primarily overlap with arterials and collectors, though they may occasionally consist of local streets. Designated transit priority corridors may evolve over time as bus and shuttle services change. Transit priority routes may incorporate design elements to prioritize transit speed and reliability and passenger experience.

Bicycle and Pedestrian Networks

As South San Francisco adds residents and jobs, more trips will need to occur via walking and biking to keep the city moving. The Active South City Plan presents the City’s roadmap for bicycle and pedestrian network rollout in the near-, medium-, and long-term, with an emphasis on creating comfortable, connected facilities that address key barriers throughout the city, such as US-101, I-280, and El Camino Real. The plan identifies changes to how infrastructure and programmatic elements can grow walking and bicycling in the city.

The Active South City bicycle and pedestrian recommendations should be implemented alongside the street concepts described above and scheduled using the priority network. Reworking the street network to accommodate multiple modes will require further analysis in some places, and tradeoffs where right-of-way is limited.

Transit
Network

Transit Network

South San Francisco’s transit network revolves around its major regional transit stations (South San Francisco and San Bruno BART Stations, South San Francisco Caltrain Station, and the South San Francisco Ferry Terminal) and three frequent SamTrans bus corridors: Route ECR (El Camino Real) and Route 292 (Airport Boulevard) running north-south, and Route 130 (Grand Avenue/Hickey Boulevard) running east-west. Additional local SamTrans bus routes, commuter shuttle routes, and community shuttle routes fill gaps in first/last mile and community connections.

As the city grows, the transit network is expected to evolve over time. In particular, South San Francisco is expected to see a substantial increase in Caltrain service in the coming years as the agency implements its Business Plan service vision, while ferry, bus, and shuttle service is also expected to grow to meet the city’s changing needs. The city can support increased regional transit service via pursuing access improvements to its stations and orienting employer transportation demand management programs around these services. The city can also support fast and reliable bus and shuttle operations by implementing improvements such as transit signal priority, bulbouts and in-lane bus stops, and bus-only lanes, particularly on its transit priority corridors.

Truck
Network

Truck Network

South San Francisco’s truck network differentiates streets that are designed to accommodate large freight trucks. These streets typically require designing for larger vehicles, including lane configurations, curb radii, and pavement types. The truck network is expected to evolve over time as land uses change; in particular, truck routes in Downtown and northern Lindenville should be phased out as more residential development occurs and the Sneath Lane extension is constructed between South Linden Avenue and Huntington Avenue.

Major Transportation
Investments

To support the city’s changing needs and transportation policy framework, various major transportation investments are needed, as summarized in the previous sections and illustrated below. The following table provides an inventory of these major transportation projects in relation to the overall transportation network, including the proposed changes and approximate cost. Projects of citywide or area-wide importance are marked as having a “high” level of City involvement, while projects with more local effects or contingent on individual developments or partnerships with other agencies are marked as having “medium” or “low” levels of City involvement. Additional information on smaller-scale street and active transportation projects may be found in planning documents such as the Active South City Plan. Although these projects alone cannot solve traffic congestion and person throughput needs, when paired with enhanced transit services and stronger transportation demand management programs, these projects can help support the city’s growth. In total, it is anticipated that the city will need roughly $1-1.2 billion in transportation upgrades over the next two decades to support buildout of the General Plan.

Notes:
Streets marked as “high” priority should provide a citywide or neighborhood-wide mobility benefit and should be advanced by the city’s public works department. Streets marked as “low” priority should be considered as redevelopment occurs at the applicable parcels and would primarily have a local mobility benefit. Streets marked as “medium” priority may be pursued by the city or considered as redevelopment occurs, and would provide a neighborhood-wide mobility benefit.
Costs are rough order-of-magnitude estimates based on previous analyses or comparable projects, rounded to the nearest $5 million in 2022 dollars. Costs do not include right-of-way acquisition if such actions are needed. Additional study is needed to refine the cost of each project.

Key Street Changes

A few streets across South San Francisco are expected to play outsized roles in accommodating changing land use and transportation conditions within the city. This section provides additional descriptions, conceptual layouts, and cross sections for these streets to serve as a starting point for planning activities.

Oyster Point
Boulevard Bus Lanes

Oyster Point Boulevard Bus Lanes

Oyster Point Boulevard will function as the primary or secondary route to access over 100,000 jobs in the East of 101 sub-area, representing one of the city’s biggest bottlenecks. In order to serve this demand and provide sufficient person-throughput along a constrained corridor, it is necessary to prioritize transit operations by adding bus lanes. Bus lanes allow for fast and reliable operations of regional express buses along with first/last mile services to Caltrain, BART and the ferry, while promoting the use of transit and stabilizing transit operating costs. Without bus lanes, bus and shuttle services will experience longer travel times and delays as the corridor develops, resulting in a negative feedback loop that increases operating costs while reducing the usefulness of these services.

Bus lanes may be accommodated on Oyster Point Boulevard between US-101 and Gull Drive through a combination of restriping, repurposing medians and turn lanes, and some widening along portions of the corridor (particularly east of Veterans Boulevard where the right-of-way narrows to roughly 85 feet). A 115 to 120 foot cross-section would accommodate a curbside bus lane and bike lane in each direction along with widened sidewalks while maintaining two through lanes for auto traffic, one left turn lane, and a median. In the westbound direction, bus-only lanes should extend to the US-101 northbound onramp to provide a seamless connection for buses traveling to San Francisco. At intersections where a second left turn lane is needed, the city may consider dynamic lane assignment to convert one left turn lane to a through-left lane during the AM peak period. To improve walkability and traffic operations while reducing conflicts along the corridor, the city may also consider restricting some lower-volume turning movements.

East Grand Avenue Bus Lanes and Caltrain Station Access

Like Oyster Point Boulevard, East Grand Avenue will serve as a key gateway to jobs in the East of 101 Area as well as the primary connection to Caltrain. In order to maximize the corridor’s person throughput, a combination of bus lanes, expanded sidewalks, and trail gap closures are needed. Bus lanes would span most of the corridor from the Caltrain station to Haskins Way, including a new westbound bus ramp directly connecting East Grand Avenue to Poletti Way and the Caltrain station. Widened sidewalks and an expanded trail along the north side of East Grand Avenue would serve pedestrians and bicyclists traveling between Caltrain/Downtown and the East of 101 Area. A 120 to 130 foot cross-section would accommodate a curbside bus lane in each direction, expanded bikeways and sidewalks, two through lanes for auto traffic, one left turn lane, and a median. While the right-of-way varies, widening of the street itself would be necessary east of Forbes Boulevard to achieve roughly 95 feet curb-to-curb (as opposed to about 70 feet existing). Eliminating the channelized right turn “slip” lanes and providing curb extensions would help improve traffic operations and reduce conflicts.

Haskins Way and Oyster Point Boulevard Bridges

The Haskins Way and Oyster Point Boulevard bridges each would each expand capacity into the East of 101 Area to the south and north, respectively, providing access to two underutilized freeway interchanges. The Haskins Way Bridge would connect East Grand Avenue and North Access Road/I-380 with a four-lane bridge, enabling a direct connection between the East of 101 Area, I-380, and US-101. The Oyster Point Boulevard bridge would connect Oyster Point Boulevard and Sierra Point Parkway with a two-lane bridge, enabling a direct connection between the East of 101 Area, Sierra Point, and US-101. Both bridges would also include an extension of the Bay Trail. While these bridges would serve critical roles in expanding street capacity, each faces complex and uncertain paths toward implementation given their high costs and potential effects on the San Francisco Bay; for these reasons, further study is necessary to confirm feasibility.

Railroad Avenue
and Sylvester Road

Railroad Avenue and Sylvester Road

Railroad Avenue would provide a new east-west street between Sylvester Road and Littlefield Road via Gateway Boulevard and Harbor Way, repurposing an underutilized rail spur. Railroad Avenue would provide several benefits to East of 101 sub-area circulation: it would expand capacity for east-west travel, enhance local access for redevelopment opportunities along Sylvester Road and East Grand Avenue, and improve pedestrian and bicycle access to Caltrain. Railroad Avenue would include two vehicle lanes along with sidewalks and bicycle lanes. The right-of-way varies between approximately 50 feet at its narrowest segments and 75 feet at its widest segments; along such wider segments, the street should also include protected bike lanes, landscaping, and a center left turn lane. Sylvester Road would connect to Railroad Avenue and include two vehicle lanes, sidewalks, and a two-way protected bikeway to minimize conflicts between vehicles and bicyclists.

El Camino Real and South Airport Boulevard Modernization

El Camino Real and South Airport Boulevard would be modernized into more walkable and bikeable ‘grand boulevards’ to support their evolution from low density auto-oriented corridors into mixed-use residential, employment, and hotel uses. Both streets have substantial right-of-way along most of the corridor: South Airport Boulevard is typically greater than 100 feet wide, while El Camino Real is typically greater than 120 feet wide. Wider sidewalks, buffered or protected bike lanes, enhanced bus stops, and landscaped medians and sidewalk buffers should be added, while maintaining existing vehicle lanes and a dedicated left turn lane. Signalized crossings should be provided for pedestrians and bicyclists at all marked crosswalks and accompanying bus stops, ideally no greater than ¼ mile apart.

Utah
Avenue

Utah Avenue

Utah Avenue is expected to grow importance as a connection between the East of 101 Area and Lindenville after completion of an overpass connecting San Mateo Avenue and South Airport Boulevard. Utah Avenue has approximately 75 feet of right-of-way east of South Airport Boulevard, which presents an opportunity for wider sidewalks and protected bike lanes while maintaining existing vehicle lanes. A new traffic signal at Harbor Way is recommended, while a signal at Wattis Way/Corey Way may also be considered as land uses densify. Adding a left turn lane (via widening Utah Avenue) or implementing a four-to-three lane road diet may be considered to enable protected left turns at these traffic signals.

Sneath Lane Extension and South Linden Avenue Grade Separation

The Sneath Lane extension from Huntington Avenue to South Linden Avenue would connect Lindenville and San Bruno with a four-lane street along with bike lanes and wide sidewalks. The Sneath Lane extension would enable more direct access to I-380, I-280, and El Camino Real from Lindenville, east-west travel between San Bruno and the East of 101 Area (via San Mateo Avenue and the proposed Utah Avenue extension) and enhanced first/last mile access to the San Bruno BART station.

The Sneath Lane extension would connect to the proposed grade separation of South Linden Avenue crossing Caltrain, realigning the grade separation as a primarily east-west route. A parallel pedestrian and bicycle crossing at Tanforan Avenue would further enhance first/last mile access to the San Bruno BART Station and enable a dedicated connection between the Bay Trail and Centennial Way Trail.

East of 101 Area Trail Network and Bay Trail-Centennial Way Trail Connection

Converting former freight railway spurs and other underused right-of-way into multi-use trails presents a key opportunity to improve first/last mile access and active transportation connectivity within the East of 101 Area. As detailed in the Active South City Plan, these trails connecting employers to regional transit could function as a backbone network for active transportation and first/last mile connections. Priority trail facilities would cover three inactive rail spurs running parallel to Eccles Avenue, Forbes Boulevard, and Harbor Way converging at East Grand Avenue and the Caltrain Station, a trail along Poletti Way to the Caltrain Station, and a trail connecting the Bay Trail and Centennial Way Trail/San Bruno BART Station via a new bridge over US-101. Some of these trail segments have already been constructed, while other gaps remain.

Funding Plan

Funding for the approximately $1-1.2 billion in capital improvements would come from a combination of city, county, regional, state, federal, and private sector sources. Key funding sources include:

City funds: The City of South San Francisco funds transportation improvements through various sources. The primary source is via a Transportation Impact Fee (Resolution 120-2020). At current fees, the General Plan buildout could generate approximately $1 billion upon full buildout of the General Plan (although not all developments may ultimately be realized). The City is also considering a community facilities district (CFD) within the East of 101 Area to augment transportation funding for the district. Preliminary funding plans for the CFD expect it could generate approximately $160 to $290 million.
Private sector funds: Some transportation projects within the city may be partially or fully funded by the private sector as developments occur, particularly new streets, streetscape improvements, or trail connections within or alongside such developments.
County/regional grants and local return: The San Mateo County Transportation Authority and the City/County Association of Governments administer various grant programs funding highway, grade separation, bicycle & pedestrian, transit, and other local transportation projects. Funding for these county programs is primarily derived from the County’s Measure A and Measure W sales taxes and Measure M vehicle registration tax. The City also receives a dedicated local return from Measure A and Measure W. Additionally, the Metropolitan Transportation Commission and Bay Area Air Quality Management District periodically administer their own grant programs to fund various transportation improvements with an emphasis on equity and VMT reduction. Grant funding varies year to year.
State grants: The State of California administers several grant programs to fund transportation improvements with a focus on the state highway system, active transportation, and safety, including the State Transportation Improvement Program, Active Transportation Program, and Highway Safety Improvement Program. Grant funding varies year to year.
Federal grants:Various grant programs are distributed to cities directly or via state, regional, and county governments. Federal grants are primarily funded via the Surface Transportation Program and Congestion Mitigation and Air Quality Improvement Program. Grant funding varies year to year.

Some projects affecting regional transportation projects identified in the General Plan are expected to be primarily funded by county, regional, state, and/or federal sources, while other projects more local in nature may be funded primarily via the City with transportation impact fees and CFD funds or via the private sector.
