It’s been said that what gets measured gets done. With the Greenroads Rating System, communities and organizations that are committed to safe and sustainable infrastructure now have a measureable way to show success.
LJB’s commitment to safety and sustainability is being showcased—and now measured—on an intersection design project for the City of Fairfield, Ohio. The intersection of State Route 4 with South Gilmore Road and Holden Boulevard is one of the city’s busiest and most accident-prone locations. The redesign will improve both the flow of traffic and the safety of those entering the intersection. While designing the project, LJB applied sustainable transportation practices that led to the project becoming Ohio’s first registered project with the Greenroads Rating System.
“With this project, we have a unique opportunity to improve safety and quality of life for our residents while also doing the right thing for future generations,” said Fairfield City Engineer Ben Mann. “I’m excited to continue working with this type of design and construction. I look forward to the positive impact it will have on our community in the long term.”
The Greenroads Rating System rates the sustainability of roadway design and construction projects. It recognizes projects that have been designed to a level of sustainability that is higher than what is considered common practice. Once a project is registered, a Greenroads professional monitors the project through to completion to ensure that certain requirements are met that will result in the project becoming a certified Greenroads project.
There are 11 project requirements that must be completed for a roadway to be considered a Greenroad, as well as 37 voluntary credits that a project team can choose to pursue. After a review process, the Greenroads Foundation assigns a project score based on the number of points earned by meeting the requirements and achieving credits. This score translates to one of four certification levels: Bronze, Silver, Gold and Evergreen. Currently, more than 60 projects worldwide have been registered to pursue Greenroads certification, and 20 have been completed and certified.
The Fairfield project includes several key components that make it a candidate for Greenroads certification. Some of these include the implementation of a light biofiltration system to improve stormwater quality, the inclusion of Dark-Sky approved fixtures that discourage light pollution, and intelligent transportation systems like countdown and LED pedestrian heads, as well as low-water vegetation. The project improves accessibility of pedestrians and bicyclists by adding new sidewalks and bicycle friendly grates. In addition to these items, the project will reuse nearly all of the existing pavement.
Aesthetically, the project will widen the Gilmore and Holden approaches, restripe State Route 4 to include a second left-turn lane and likely change the horizontal alignment to the Holden and Gilmore approaches. The project will also convert the existing span wire signal to a standard mast arm design that connects to the city’s central signal system.
The project is scheduled for completion in November 2016.
