What are the different types of multimodal transportation studies?

  • 1. Development Applications
  • Development Special Use Permits
  • Coordinated Development Districts
  • 2. Small Area Plans
  • Larger “scope” plans that examine land use
  • 3. City-Initiated Studies
  • City Projects (generally smaller scope)
  • Studies based on larger public process, as programmed in the

City Capital Improvement Plan

What do multimodal transportation studies assess?

  • Existing transportation conditions:
  • Vehicular travel
  • Parking occupancy/capacity
  • Transit service and infrastructure
  • Pedestrian/bicycle facilities
  • Future transportation conditions:
  • With new development
  • Without new development

Why are multimodal studies run for Development Applications?

  • Help Transportation and Environmental Services staff

determine immediate impacts of development

  • If impacts detrimental, staff works with applicant to revise

application or provide mitigations

  • If impacts are acceptable, staff works with the applicant to

provide community benefits

  • In both cases, staff works to ensure mobility is

acceptable per the City’s Transportation Master Plan

Why are multimodal studies run for Small Area Plans?

  • Provides macro-level analysis of what a larger area

can “hold” without impacting existing residents / businesses

  • Inventory pedestrian/bicycle/transit improvements

for future development mitigations & City projects

  • Help guide staff in review of future development

applications

Why are multimodal studies initiated by staff?

  • Assess, reassess, and/or support planned capital

improvements

  • Sometimes triggered by citizen request, as with

the Central City Traffic Study

  • Transportation studies proposed through a public

process must be funded through the City’s CIP

How does the City use the information?

  • For development applications, staff determine if

mitigations are necessary

  • Mitigations must be linked to development impacts to

protect against potential litigation

  • Mitigations include (but are not limited to):
  • New signals / signal timing adjustments
  • Pedestrian / bicycle / transit facilities upgrades
  • Transportation Demand Management plans and

contributions

How does the City use the information?

  • For small area plans, staff determine if capital

improvements are necessary

  • Phasing and triggers noted in Plan or its associated

appendices to inform development community

  • For City-initiated projects, staff determine if capital

improvements, signal adjustments, speed adjustments, etc. are necessary.

How do studies help the City see the big picture?

  • All studies account for “background development”
  • All studies assume regional growth in trips,
  • riginating both within and beyond Alexandria
  • City uses Washington Council of Governments data to

inform growth assumptions

  • Each study presents the most accurate picture of

future conditions based on best assumptions

Proposed Revisions to Existing Transportation Guidelines

  • Additional time for City staff review based on context
  • Additional parking study requirement for small projects
  • New requirement to use software selection tool

(consistent with VDOT requirements)

  • New policy statement on mitigations that supports

Alexandria’s Multimodal Vision

  • Flexibility to coordinate study requirements with small

area plan updates
