The 155/60 rule refers to the timeframes outlined in Section 24VAC30-155-60 of the Virginia Administrative Code for the Virginia Department of Transportation (VDOT) to respond to requests for scope of work meetings regarding Traffic Impact Statements (TIS). This rule is crucial for developers and localities navigating the approval process for projects impacting transportation infrastructure. Understanding these timelines helps ensure projects proceed efficiently.
Decoding the 155/60 Rule: Time is of the Essence
The 155/60 rule dictates VDOT’s response times for scope of work meeting requests related to TIS. These meetings are critical for aligning project plans with VDOT requirements and ensuring a smooth development process. The rule differentiates response times based on projected traffic impact:
Projects with Less Than 1,000 Peak Hour Vehicle Trips:
- 30 Days to Respond: VDOT has 30 days to respond to a request for a scope of work meeting from a locality or applicant.
- 60 Days to Meet: The meeting itself must be scheduled within 60 days of VDOT receiving the request. This meeting is optional and can be initiated by the locality, the applicant, or both.
Projects with 1,000 or More Peak Hour Vehicle Trips:
- Mandatory Meeting: A scope of work meeting with VDOT is mandatory for projects generating 1,000 or more peak hour vehicle trips.
- 30 Days to Respond: VDOT has 30 days to respond to the locality or applicant’s contact regarding scheduling the meeting.
- 60 Days to Meet: The meeting must be scheduled within 60 days of the initial contact. Both the locality and the applicant must participate.
The Importance of Scope of Work Meetings in Traffic Impact Studies
Scope of work meetings facilitate a collaborative discussion between VDOT, the locality, and the applicant. Key topics discussed include:
- TIS Elements: Determining the necessary components of the TIS based on the project’s scope and potential impact. This can range from basic traffic counts to complex simulations and analyses.
- Methodology and Assumptions: Establishing the agreed-upon methods and assumptions for data collection, analysis, and forecasting.
- Local Requirements: Identifying any additional requirements imposed by the local jurisdiction.
These discussions ensure everyone is on the same page, minimizing potential delays and revisions later in the process. A well-defined scope of work streamlines the TIS preparation, leading to a more efficient project timeline.
Beyond the 155/60 Rule: Key Considerations for Traffic Impact Statements
While the 155/60 rule governs meeting timelines, the overall TIS process involves many other critical aspects:
- Data Collection: Accurate and comprehensive data collection is paramount. This includes traffic counts, turning movement studies, and potentially pedestrian and bicycle counts.
- Trip Generation and Distribution: Utilizing appropriate methodologies (often from the Institute of Transportation Engineers – ITE) to estimate trip generation and distribute those trips onto the surrounding road network.
- Level of Service Analysis: Assessing the impact of the development on the Level of Service (LOS) of nearby intersections and roadways. This involves using specialized software and adhering to specific guidelines.
- Mitigation Measures: Proposing and analyzing potential improvements to mitigate any negative impacts identified in the study. This could include roadway widening, signal modifications, or other traffic management strategies.
Conclusion: Navigating Virginia’s Traffic Impact Study Requirements
Understanding the 155/60 rule is essential for developers and localities in Virginia. Adhering to these timelines and engaging in productive scope of work meetings are crucial steps in the development process. By working collaboratively with VDOT and adhering to established guidelines, projects can move forward efficiently while minimizing negative impacts on the transportation system.
