Introduction Mobility Complete Streets Manual
Introduction
I
n the last decade, instead of perpetually requiring that a roadway be
widened, the City has begun to “live within its means” by working
within existing roadway widths to accommodate a balance of all modes of
transportation, and to meet the needs of all users (pedestrians, bicyclists,
transit riders, and motorists) within the right-of-way. The Complete
Streets concept values the importance of designing and operating
streets in order to provide safe and convenient access for all users.
In the City of Los Angeles, the Complete Streets concept is promoted by:
1. Acknowledging that all streets are Complete Streets
2. Implementing a layered network approach to Complete Streets
by selecting specific regional streets to be enhanced for a
particular prioritized mode (transit, bicycles, pedestrians, or
vehicles) while still providing access for all other modes.
While the Complete Streets Standards in this Manual focus primarily on
physical changes to the right-of-way and roadway areas, it is important to
note that the operation and management of a street also play critical roles
in ensuring that it is truly “complete” and meets the needs of all users.
These standards represent the best practices that are currently being applied
in both California and nationwide to meet standards set by the California
Complete Streets Act. Some of these standards are in conflict with the Bureau
of Engineering (BOE) Street Design Manual as well as current Los Angeles
Department of Transportation (LADOT) policies and practices. Until these manuals
and/or companion standard plans are modified, the Complete Streets Standards
presented in this manual shall supersede all related existing city regulations
and policies. Complete Street standards that are in a demonstration phase
and have yet to be incorporated into the California Manual on Uniform Traffic
Control Devices (CA MUTCD) will require provisional approval. This document
provides a foundation for Complete Streets standards and is meant to be a
launching point for the City’s implementation of a Complete Streets program.

Mobility Complete Streets Manual Introduction
Organization
The Complete Streets Manual is presented in three parts composed of 15 sections:
section 1: Street Identification
Defines each of the City’s street classifications included in the S-470
Standards and establishes targeted operating speeds for each roadway type
as well as other special typologies occuring in the public right-of-way.
Describes the role and characteristics of a Complete Street as well
as how it will be implemented through the enhanced network.
section 2: Sample Cross-Sections
Presents sample complete street cross-sections.
sections 3-15: Sidewalks, Roadway, Bicycle Facilities, Transit, Intersections,
Signalization, Public Space, Paths, Signs
Provides planners, city engineers and urban designers with design
standards and guidelines to apply when determining specific street
design improvements within the roadway and/or overall right-of-way.
