Services

Transportation planning and design.

Traffic and parking studies, vehicle miles traveled (VMT) screening and California Environmental Quality Act (CEQA) transportation analysis, site access and circulation, and transportation plans, specifications, and estimates (PS&E), carried from early decisions through agency review.

Transportation Planning

Traffic, parking, access, and VMT analyses supporting project entitlements, site design, and environmental review.

01

Traffic Impact Studies

Traffic studies that document how a proposed development is expected to interact with the surrounding transportation network and identify practical operational improvements.

Study scope
  • Study scoping, existing conditions, and traffic data collection
  • Trip generation, distribution, assignment, and forecast scenarios
  • Intersection and corridor operations, with level of service where required
  • Transit, pedestrian, and bicycle analysis where applicable
  • Queue, storage, and access effects where needed
  • Technical findings, improvement concepts, and agency-ready documentation
When you need this
  • Projects adding peak-hour trips above an agency’s screening threshold
  • Development applications and entitlement review
  • An agency scoping letter or study condition
02

VMT & CEQA Transportation Analysis

Project-level VMT documentation supporting CEQA review, from screening through mitigation.

Analysis includes
  • VMT screening under local and statewide CEQA guidance
  • Project-level VMT analysis, travel model coordination, and threshold evaluation
  • Mitigation and transportation demand management (TDM) strategy development where needed
When you need this
  • Entitlement applications requiring CEQA review
  • Projects that exceed local VMT screening thresholds
  • Transportation sections for Initial Studies, Mitigated Negative Declarations, and Environmental Impact Reports
  • Screening memos to document CEQA exemptions
03

Site Access & Circulation

Focused review of how vehicles, service traffic, emergency responders, transit, pedestrians, and bicyclists enter, leave, and move through a proposed site.

Review includes
  • Driveway location, spacing, and frontage access
  • Sight distance checks at driveways and intersections
  • Queuing, loading, and vehicle stacking at gated entries, and their effects on access
  • Service, emergency, and design vehicle turning paths
  • Internal vehicle, pedestrian, and bicycle circulation
  • Transit stop locations, bus turnouts, and rider paths between stops and building entrances
  • Practical recommendations for site and frontage plans
When you need this
  • New or modified driveways and site plans
  • Drive-throughs, schools, loading areas, and gated access
  • Sites with constrained frontage or circulation
  • Early feasibility and transportation due diligence
04

Parking Studies

Parking studies that compare proposed supply with code requirements and expected demand.

Study scope
  • Parking code review and evaluation of proposed parking supply
  • Demand analysis by use, location, and time period
  • Review and justification of lower parking supply or shared parking
  • Occupancy, utilization, and turnover surveys when relevant
  • Parking management and transportation demand management (TDM) recommendations to support the proposed supply
When you need this
  • Projects proposing less parking than required by code
  • Mixed-use developments with complementary peak periods
  • Changes of use and constrained sites
  • Existing facilities with reported parking concerns
  • Right-sizing supply where parking minimums are reduced or removed

Transportation Design

Transportation plans, specifications, and estimates (PS&E) prepared to agency standards.

05

Traffic Control Plans

Project-specific traffic control plans for work zones affecting lanes, shoulders, sidewalks, and other public right-of-way.

Plan package
  • Project-specific work zone layout and closure limits
  • Temporary signs, tapers, channelization, and buffers
  • Pedestrian and bicycle routing through the work area
  • Staging, phasing, and detour plans where required
  • Permit-ready traffic control sheets coordinated with agency requirements
When you need this
  • Lane, shoulder, parking, or sidewalk closures
  • Utility work in public streets
  • Frontage improvements affecting traffic or pedestrians
  • Encroachment permit submittals
06

Signing & Striping Plans

Permanent signing and striping plans for streets, site access, frontage improvements, and roadway reconfigurations.

Plan package
  • Permanent signing and striping plan sheets
  • Sign identification, schedules, and marking details
  • Lane lines, arrows, legends, crosswalks, and curb markings
  • Removal or relocation of conflicting signs and striping
  • Parking, loading, and curb-use restrictions where applicable
  • Coordination with final roadway geometry and signal plans
When you need this
  • New site access, driveways, and frontage improvements
  • Restriping after lane reconfigurations
  • Signing for new traffic patterns
  • Development conditions of approval
07

Traffic Signal & Illumination Plans

Traffic signal and roadway illumination design and modification plans coordinated with roadway geometry, signing and striping, pedestrian crossings, and agency standards.

Plan package
  • Signal plan sheets including layout and phasing
  • Poles, mast arms, pedestrian equipment, and accessible features
  • Conduit, pull boxes, cabinets, service, and interconnect layouts
  • Illumination layout and equipment schedules where required
  • Supporting photometric calculations as applicable
When you need this
  • New signals and signal modifications
  • Development or frontage work affecting an intersection
  • Detection, conduit, or interconnect upgrades
  • Roadway or intersection illumination additions and modifications
08

Geometric & Channelization Plans

Geometric layouts for street, frontage, driveway, and intersection improvements.

Plan package
  • Lane, median, and channelization layout plans
  • Intersection, driveway, and frontage improvement geometry
  • Turn pocket, taper, and storage length design
  • Curb return geometry and design vehicle checks
  • Coordination with signing, striping, signal, and permit plans
When you need this
  • Lane reconfigurations and turn pockets
  • New intersections, driveways, and medians
  • Curb line and frontage modifications
  • Access improvements identified in a traffic study or conditions of approval
