Today’s increasingly stringent environmental regulations continue to create the need for Low Impact Development (LID) and Green Infrastructure (GI) management on project sites. New and innovative ways must be used to limit hard surfaces such as parking lots, walkways, and emergency access lanes. Land access is at a premium, and areas of environmental protection are increasing, requiring builders and engineers to work with regulators to utilize both LID and GI practices.
Porous pavements are an easy and economical way to reduce the impervious surfaces onsite, and restore the natural water cycle close to its source. They have the added benefit of reducing the size of above ground detention ponds and conveyance and treatment infrastructure. Stormwater diversion channels, roadside swales, and drainage ditches can be constructed with low maintenance solutions, protecting against erosion and overflow concerns. Living green walls increase the amount of vegetation onsite, help promote water filtration from higher elevations, and allow access to more valuable land.
- Learn what Low Impact Development and Green Infrastructure means for residential and commercial project sites.
- Cover the regulations governing these practices and how they have been met with traditional construction methods.
- Learn about porous pavement options and their benefits and limitations related to infiltration, runoff reduction, traffic and performance.
- Understand how to manage urban stormwater through design of vegetated channels that replace hard surface systems and mitigate flooding potential.
- Explore different applications for low-impact products, and understand how they fit with the goals of LID and GI.
