2025 ACEC-NH & NHDOT Technical Exchange Conference

Session 3A: Building Sustainability into Your Projects
Speakers: Diane Mas, Fuss & O'Neill; Nicole Fox, Fuss & O'Neill; Kristen Hayden, Fuss & O'Neill

- Transportation infrastructure is a substantial investment, so maximizing its longevity, functionality, and other benefits is important to transportation agencies, communities, and businesses. Approaching the engineering design process with that viewpoint results in reduced maintenance and repair costs, improved operational continuity, and co-benefits related to environmental and human health. In this session, we’ll provide some examples of how this approach to long-term benefits have been incorporated into drainage design and complete streets design in New England . Attendees in this session will gain an understanding of how to connect their design decisions to long-term benefits and articulate the rationale for design decisions to technical and non-technical audiences.

Session 3B: Resilient Paving: Pervious Pavement for Flood Mitigation
Speaker: Jim Pappas, AECOM
- Delaware is the lowest lying state in the nation, and therefore has experience with flooded roadways. Some of these flooded roadways are to coastal communities that only have single access points. When these roadways are inaccessible, the communities are cut off from all movements including emergency services.

After reviewing various mitigation options, the ultimate decision was made to use a permeable asphalt pavement to overlay the existing roadways to attempt to increase the resiliency of the roadways.

The first paved location has now been in service for over 2 years with no noticeable deterioration or pavement quality concerns.
