Traffic & Transportation Engineering

Traffic & Mobility


The City's General Plan summarizes a set of recommendations for long-range transportation improvements in the City of San Gabriel. The improvements are contained in the Mobility Element of the General Plan. The General Plan Mobility Element establishes functional classifications for the City’s arterial street system.

Since not all roadways are at their ultimate configurations as implied by those classifications, improvements will be carried out over time to achieve those configurations. The proposed long-range improvements include roadway modifications to achieve the Mobility Element Functional Classification and intersection improvements to achieve level of service performance thresholds. The intersection improvements are generally associated with the roadway improvements but in some cases provide “augmentation” to provide satisfactory level of service (Level of Service (LOS) “D” or better).

Complete Streets: Safe, Efficient & Green


Many of the city's roadways were built with an emphasis on serving automobiles above all other modes of travel. Today, we recognize the importance of serving all users -- including pedestrians, cyclists, transit riders, as well as motorists. Streets also represent a large amount of hard surface area that no longer allows rainwater to absorb into the soil and recharge the groundwater needed for drinking and irrigation. By redesigning our streets to be "Complete" and "Green", we will make streets that are safe, comfortable, and accessible to all users and environmentally friendly, sustainable, and low-maintenance. The transformation to Complete Streets will take decades, but it represents a philosophy that we have incorporated into most of our street projects, including the Las Tunas Pavement Rehabilitation Project, Citywide Bus Shelter Project and San Gabriel Boulevard Streetscape Project.

San Gabriel Valley Bicycle Master Plan
The City of San Gabriel is one of five cities preparing a Regional Bike Master Plan. In 2012, BikeSGV partnered with Day One and five cities - Monterey Park, San Gabriel, Baldwin Park, El Monte, and South El Monte - to develop a regional bicycle master plan in the San Gabriel Valley.

In January 2013, Day One was awarded a grant through the Healthy Eating Active Living (HEAL) Initiative of the Los Angeles County Department of Public Health, PLACE Program (Policies for Livable, Active Communities and Environments).

A Bike Master Plan is a comprehensive planning document that guides the development of bicycle infrastructure projects, programs and policies. A plan typically includes the goals and objectives; an inventory of existing conditions; community input to identify desirable routes; proposed bikeways; and policies and programs that support bicycling as a viable form of transportation, recreation and physical activity. A plan will also prioritize infrastructure projects and identify potential funding sources for implementation.

For more information, visit the SGV Bike Master Plan website at www.dobikeplan.com. If you would like to participate in developing this plan for San Gabriel, please contact Daren Grilley at dgrilley@sgch.org.

Metropolitan Transportation Authority & SCAG

Metro is the Metropolitan Planning Organization (MPO) that coordinates the Transportation Improvement Plan (TIP). Metro coordinates with the Southern California Association of Governments (SCAG), which prepares the Regional Transportation Improvement Plan(RTIP). The RTIP is available online. RTIP projects are developed, updated, and revised through the Metro’s Program Metro website. SCAG is the agency responsible for preparing the Regional Transportation Plan (RTP).

San Gabriel Valley Council of Governments(SGVCOG)


SGVCOG assists with obtaining federal funds for local projects. Engineering Division participates in SGVCOG’s Transportation Committee. The Committee usually meets monthly.

Parking


Overnight parking is not allowed on City streets or in City parking facilities between the hours of 2 and 6 a.m. daily. If you need a permit for temporary overnight parking, you may obtain one from the machines located in front of the Parks and Recreation Building located at the intersection of Mission Drive and Broadway and in front of the Police Department Building located at 625 South Del Mar Avenue.

For long-term overnight parking permits, contact the Finance Department at City Hall. This map shows the location of public parking facilities in the city. For proper signage of parking on private property, see the Private Property Parking Signs handout.

Traffic Studies


Traffic studies may be required for projects. Review of existing conditions and impacts from traffic added by the project will determine what traffic control measures will be required for the project.

Union Pacific Railroad (UPRR)


The original railroad in San Gabriel was Southern Pacific Railroad that was acquired by UPRR. It follows an alignment in a dedicated right of way known as the “Alhambra Subdivision”. Railroad crossings are located at Ramona Street, Mission Road, Del Mar Avenue, and San Gabriel Blvd. The Alameda Corridor-East Construction Authority is responsible for a project involving the engineering and construction of grade separations at these locations. The project is formally known as the San Gabriel Trench Grade Separation Project. Construction for the project started in 2012, and it is expected to be completed by 2017. The project consists of bridges at the four crossing locations and a trench to allow the railroad to operate below grade. The relocation of utilities, storm drain & sewer construction, and improvements to the adjacent streets are also included in the project.
