F&D International is pleased to announce the completion of the design and installation of porous asphalt streets in the Town of Nederland last week. This is the first high altitude installation of porous asphalt in Colorado; at an elevation of 8,300 feet, Porous Asphalt the F&D Engineering team had to develop a solution incorporating leading sustainable transportation design and construction techniques never before used in such an extreme climate and high altitude location.

With the primary element of the project focusing on reducing imperviousness and increasing infiltration, our engineers designed every portion of the project to achieve zero surface runoff. Previous surfaces were introduced throughout the project to accommodate all stormwater surface runoff with zero direct discharge into North Beaver Creek. Porous asphalt was placed on Second Street and is the capstone of the project; the pavement section is first of its kind at 8,300 feet and designed withstand extreme weather conditions with 100% infiltration and zero direct discharge to the adjacent creek or classic stormwater infrastructure systems.
