Operations

Emergency Operations Section

The Emergency Operations Section develops emergency plans, implements employee response training programs, and complies with National, Federal, State, and local requirements.

In the event of an emergency, all Street Services Divisions become an integral part of the emergency response.

Engineering Services Division

The Engineering Division of the Bureau of Street Services provides design, project management and construction management services for bikeway, streetscape, and various street improvement projects constructed by the Bureau of Street Services. Another major responsibility is to secure available Federal and State grant monies that help fund many of these projects through programs such as the MTA Call for Projects and Caltrans' Safe Routes to Schools Program.

Investigation & Enforcement Division

The Investigation and Enforcement Division works closely with the various communities of Los Angeles by assigning a supervisory Investigator to each section of the city and an Investigator to smaller Districts to provide focused municipal enforcement.

Street Renewal Division

The Street Renewal Division's (formerly known as the Resurfacing and Reconstruction Division) mission is to maintain all improved streets, alleys, and related throughways in perpetually good to excellent condition while providing desirable standards of safety, appearance, and convenience for residents and the traveling public within our jurisdiction. We have a street network comprised of 28,000 lane miles of streets, and 800 miles of alleys. The City of Los Angeles has the largest municipal street system in the nation.

Street Maintenance Division

The Street Maintenance Division provides some of the most basic yet essential services the Bureau has to offer, ranging from pothole repair to cleaning of the roadway after a special event. We perform daily maintenance for one of the largest and most congested municipal street networks in the nation and respond 24/7 to emergency conditions. We fill potholes and make small asphalt repairs to areas that don’t require a full resurfacing or reconstruction. The Division's motor sweepers regularly clean hundreds of street sweeping routes to keep trash out of our rivers and ocean and prevent local flooding due to blocked storm drains.

Urban Forestry Division

The Urban Forestry Division manages trees and plants contained in the public right-of-way, including approximately 700,000 street trees and several million square feet of landscaped median islands. The Division also has authority over certain native tree species on private property that are protected by the City of Los Angeles.

Division crews are focused on emergency tree work, while contractors hired by the division provide most of the proactive tree trimming and also maintain landscaped median islands.

Support

Administration Division

The Administration Division is responsible for the Bureau-wide administrative functions of human resources, contract administration, training coordination and board report processing. The Division also assists with providing various general and miscellaneous administrative activities that are required to support and maintain operations within the Bureau.

Advanced Planning & Asset Management Section

The Advanced Planning & Asset/Grants Management (APGM) section is responsible for developing and managing StreetsLA’s asset management framework and integration of technology to ensure alignment with the bureau’s vision, mission, and policy. The focus is on the business processes for resource allocation and utilization with the objective of better decision-making based on quality information regarding the assets and well-defined objectives expressed as “Levels of Service.” When fully implemented, an Asset Management program will build, preserve, and operate street services more cost-effectively with improved asset performance, deliver to customers the best value for public tax dollars spent, and enhance the credibility and accountability of StreetsLA to all stakeholders.

APGM is responsible for the management of a $300 million grant portfolio with a variety of federal-aid, state, and local funding sources. Long term goals include the development of new capital projects to capture a holistic streetscape vision for the city to improve equitable mobility, greening, and cultural identity for all Angelenos.

External Relations Team

The StreetsLA External Relations Team supports StreetsLA's engagement with stakeholders, its development and coordination of policy, and its response to service requests. It works closely with the Public Affairs Office of the Board of Public Works to promote the work of the bureau and respond to media inquiries. It oversees the Constituent Call Center, is responsible for social media and serves as a liaison to council offices and other key partners. Reach us at StreetsLA.ERT@lacity.org.

Financial Management Division

The Bureau of Street Services’ Financial Management Division (FMD) manages all of the Bureau’s finances and is responsible for the fiscal solvency and administration of (8) eight Bureau Budgetary Programs and a $230+ million budget with multiple special funds. FMD plans, develops, implements and monitors the Annual Budget, as well as handling interim fiscal changes, mandates, and Council actions throughout the year.

FMD's many functions include Budget, Financial Administration, Special Funds Billing and Revenue Management, CIEP Administration/Grants Management, Audit Compliance, Fiscal Systems Management and Cost Accounting, Procurement and Accounts Payable, and Payroll and Timekeeping.

Information Technology Section

The Information Technology Section (ITS) is responsible for providing modern infrastructure and strategic application solutions that modernize and transform the way the Bureau of Street Services delivers services to City Angelinos, as the Bureau strives to provide world-class Street Services.

Methods & Standards Division

The Methods and Standards Division (MSD) is primarily responsible for using performance metrics to evaluate key staff deliverables in the Street Maintenance Division, Urban Forestry Division, Investigation and Enforcement Division and the Pavement Preservation Program. StreetsLA is using data and performance measures to optimize workforce allocation and prioritize service deliveries and ensure continuous improvement in StreetsLA's service delivery. The Methods and Standards Division (MSD) is responsible for conducting monthly StreetStat meetings where staff performances are evaluated, and where improvements are identified and implemented.

Pavement Management Section

Pavement Management Section is responsible for inventorying the city’s street assets, identifying pavement condition using a methodology called the pavement condition index (PCI), and recommending rehabilitation strategies to preserve and improve the overall conditions of the city streets.

We manage this by utilizing a Pavement Management System called Micro Paver to optimize the street network on a limited budget, define the most appropriate type of pavement preservation work, and to ensure that the maintenance and rehabilitation work is performed with cost-effective repair strategy and at the proper time.

Risk Management & Safety Section

The Risk Management & Safety Section (RMSS) administers the civil litigation, claims, occupational health & safety, environmental compliance, facilities maintenance, workers' compensation, disability and return to work programs. Our goal is to ensure the well-being and safety of our employees and communities by complying with all applicable safety and environmental laws, advocating for and managing the disability benefits of our employees and facilitating all loss control and prevention activities affecting the Bureau.

Fulfilling these duties takes on many shapes and forms, from representation at City Council hearings and budget meetings to safety inspections and maintenance of critical infrastructure. The RMSS Team is comprised of dedicated support staff, professionals and subject matter experts with specialized education, training and skills.
