Transportation Development Review
One of the most important ways the Montgomery County Planning Board implements the vision of the County’s General Plan and master plans is by reviewing proposed development and deciding on subdivision requests. The following transportation resources should be consulted to ensure consistency with county master plans, policies, standards and practices.
General Transportation Resources
All development applications must substantially conform to transportation recommendations in area master plans and functional plans, including:
- Bicycle Master Plan and map
- Corridor Forward: The I-270 Transit Plan
- Countywide Transit Corridors Functional Master Plan
- Master Plan of Highways and Transitways Plan and map
- Pedestrian Master Plan (forthcoming)
- Purple Line Functional Plan
The following resources will assist development applicants in conforming to county standards, guidelines and best practices.
- Complete Streets Design Guide: Provides policy and design guidance to government agencies, consultants, private developers, and community groups on the planning, design, and operation of roadways for all modes of transportation.
- Bicycle Parking Guidelines: Identifies requirements in the county code and best practices.
- Bikeway Branding Guidelines (forthcoming): A cohesive brand identity for the bikeway network through logos and wayfinding.
- Bicycle Facility Design Toolkit: An overview of the types of bicycle facilities recommended in the Bicycle Master Plan.
- Protected Intersection Checklist: A tool to assist applicants in designing protected intersections. View the training video and presentation slides.
The Planning Board has established transportation-related policies for development projects.

Local Area Transportation Review (LATR)
In 1973, the County Council adopted an Adequate Public Facilities Ordinance and granted the Planning Board administrative oversight to ensure that adequate public facilities exist to accommodate growth. Since then, Montgomery County has considered the impacts of development on the transportation system, guided by the County Council’s Growth and Infrastructure Policy, which is reviewed on a four-year cycle.
The 2022 LATR Guidelines, Version 2 implement the Growth and Infrastructure Policy and guide applicants in evaluating a proposed development’s impacts on the nearby transportation system. All projects that generate 50 or more net new peak hour person trips are subject to the Growth and Infrastructure LATR requirements, which are detailed in the LATR Guidelines.
- Scoping Form: Prior to initiating a Local Area Transportation Review study or transportation exemption statement, a scope of work must be approved by relevant agencies, including the Montgomery County Planning Department, the Montgomery County Department of Transportation, and the State Highway Administration (where relevant).
- Transportation Policy Area Map: A map that identifies the county’s transportation policy areas.
- Transportation Management Districts Map: A map that identifies the county’s six Transportation Management Districts.
- LATR Mitigation Tracking (forthcoming): A webpage that identifies pedestrian, bicycle and bus transit deficiencies that will be mitigated by development and capital projects.
- Montgomery Planning Count Database: A database of existing pedestrian, bicycle and motor vehicle counts.
- MDOT Internet Traffic Monitoring System: A database of existing pedestrian, bicycle and motor vehicle counts.
- Count Data Submission: All pedestrian, bicycle and motor vehicle counts must be submitted digitally using this tool. View instructions for using the data submission tool.
LATR Proportionality Guide
The LATR Proportionality Guide ensures that offsite transportation improvements are not out of proportion with a project’s impact on the overall safety and functionality of the transportation system. For more information on the LATR Proportionality Guide, see Section VIII of the 2022 LATR Guidelines, Version 2.
