I’ll bet you didn’t think a street reconstruction project could go ‘green,’ did you? The design concept for the Bagby Reconstruction was greatly influenced by the national Greenroads™ Program and is conceived to incorporate sustainable practices. Such as, you ask? The Bagby and Pierce Street Reconstruction Project will feature numerous rain gardens, which aids in the decontamination of water before it’s released into Buffalo Bayou.

And what exactly is a Green road?
What is Greenroads?
Greenroads is a sustainability rating system for roadway design and construction. It is applicable to all roadway projects including new, reconstruction and rehabilitation (even overlays), bridges, you name it. If it is a project where a road is involved, you can use it.
Greenroads is a collection of sustainability best practices, called "credits," that relate to roadway design and construction. Achieving these credits can earn points toward a total score for the project, and in general, this Greenroads™ score can be used as an indicator of sustainability for the roadway. Four different certification levels (rating) are available depending upon total score on a voluntary basis.
