Virginia Department of Transportation 4 4 Project Benefits ▪ Adds new capacity ▪ Provides new travel choices ▪ Decreases travel times during peak periods ▪ Reduces cut-through traffic on local roads ▪ Improves safety in the study area by: ▪ Taking cars off local roads ▪ Reducing the weaving needed to access the George Washington Memorial Parkway

Virginia Department of Transportation 5 Environmental Review Process The National Environmental Policy Act (NEPA) requires: ▪ Consideration of potential environmental consequences of transportation improvements; ▪ Documentation of the environmental analyses; and ▪ Making the information available to the public for comment

Virginia Department of Transportation 6 Environmental Review Process – Technical Studies Conducted an Environmental Assessment (EA) in accordance with NEPA including: ▪ Air quality analysis ▪ Alternatives analysis ▪ Hazardous materials ▪ Historic resources ▪ Indirect and cumulative effects ▪ Natural resources ▪ Preliminary noise analysis ▪ Socioeconomic and land use analysis ▪ Traffic analysis

Virginia Department of Transportation 7 7 Environmental Assessment Findings

Environmental Resource Resource Summary Property Impacts 89 properties with potential impacts No relocations Community Facilities 5 community facilities: Partial property acquisition 9 existing trail/bicycle facilities: Temporary impacts 4 proposed trail/bicycle facilities by others: Temporary impacts Environmental Justice No disproportionately high and adverse effects (Minority/Low-income) Historic Properties Anticipated “No Adverse Effect” determination from the Virginia State Historic Preservation Officer (SHPO) Section 4(f) Protected Properties Anticipated de minimis impact finding for Scott’s Run Nature Preserve and the George Washington Memorial Parkway Section 6(f) Protected Properties Anticipated impacts to Scott’s Run Nature Preserve Noise – Based on Preliminary Noise 9 existing barriers physically affected will be replaced Study 3 of the 9 existing barriers would be lengthened 1 new barrier determined to be feasible and reasonable

Virginia Department of Transportation 8 8 Environmental Assessment Findings Environmental Resource Resource Summary Air Quality No adverse impacts to air quality; no violation of the National Ambient Air Quality Standards Wetlands and Streams Streams: Approximately 13,000 linear feet located within the LOD (Anticipated 3,000 linear feet of impact) Wetlands: 20 acres within the LOD (Anticipated 4.5 acres of impact) Floodplains Approximately 60 acres of floodplains are within LOD No increase in flood levels or probability of flooding expected Wooded Areas Approximately 118 acres within the LOD Wildlife and Habitat Approximately 234 acres within the LOD (Anticipated 66 acres of impact) No new habitat fragmentation or elimination of existing wildlife passages is anticipated Threatened and Endangered Species Tree clearing could impact potential suitable habitat for three bat species Streams and floodplains that contain potential habitat for wood turtles would be impacted These impacts are based on the proposed Limits of Disturbance (LOD). During final design, efforts will be made to reduce the project footprint and minimize impacts.

Virginia Department of Transportation 9 9 Scope of Traffic Analysis ▪ Operational and safety analysis ▪ I-495 and Dulles Toll Road mainlines ▪ Arterials within study corridor ▪ Traffic and Transportation Technical Report ▪ Interchange Justification Report ▪ Comparison of build alternative (with options) versus no-build alternative ▪ 2025 interim year ▪ 2045 design year ▪ Traffic analysis shows benefits to: ▪ Person throughput ▪ Travel times and traffic delay ▪ Local streets

Virginia Department of Transportation 10 Traffic Analysis Results Move More People

▪ 2045: Moves 7,600 more people per hour in both directions combined ▪ 2025 with Managed Lanes System: Moves 5,400 more people per hour in both directions combined ▪ 2025 Prior to Maryland Managed Lanes System: Moves 2,500 more people per hour in both directions combined

Virginia Department of Transportation 15 Traffic Analysis Results Improve Safety ▪ Project safety and operational improvements reduce crashes by 20 percent in 2045. ▪ New direct access ramps to the Express Lanes at the DTR and the George Washington Memorial Parkway – eliminates need to cross four lanes to access the express lanes entrances / exit points. ▪ The project improvements that would make the corridor safer: ▪ Roadway features, such as increased acceleration and deceleration lanes, and new auxiliary lanes; and ▪ Reconfigured shoulder in the northbound direction during peak periods. ▪ These types of improvements are expected to reduce rear-end and side- swipe collisions.

Virginia Department of Transportation 16 Noise Analysis Process

Identify noise receptors Finalize noise barrier designs once the project has received design approval

Perform noise measurements at representative receptors along the corridor Obtain VDOT Chief Engineer approval

Perform noise modeling Obtain FHWA concurrence Identify impacts (is noise mitigation warranted?) Solicit public input from benefited

Final Design Final property owners and renters Design and assess mitigation (typically (voting process) WE ARE noise walls) HERE NEPA and Preliminary Design Preliminary and NEPA Present noise study results and Incorporate approved noise wall(s) into preliminary noise wall locations at public the final road design construction plans hearings
