396541 - Construct the Low Maintenance BMP That You Designed: Green Infrastructure Construction and Inspection

Wednesday, June 6
2:00 PM - 3:30 PM
Location: Mirage Room

Design of green infrastructure or Low Impact Development (LID) practices is only a part of managing stormwater runoff. If the practices are not properly constructed and maintained they will not function as they are designed. Maintenance of green infrastructure and LID practices has been widely discussed however, little guidance has been provided on properly constructing or inspecting the construction of green infrastructure or LID practices. There are many variables, including construction practices and material delivery, that can have a significant impact on the performance and function of green infrastructure practices. For example, compaction of the subgrade can have a significant impact on infiltration and overall performance of bioretention areas and permeable pavement and should be avoided. Materials used in construction can also have a significant impact. It is important to have a trained person onsite who can determine if the gravel used in the drainage layer has been washed and free of fines and if the bioretention soil media contains the amount and quality of organic material specified in the construction documents.
This presentation will give a brief overview of the proper phasing of construction, inspection of materials upon delivery, a multitude of proper construction practices, and field testing and verification to ensure green infrastructure and LID practices are properly constructed and function as they are designed. The focus will be on specific construction mistakes that have been observed to be made consistently by contractors and how inspectors and resident engineers can prevent those mistakes from occurring on their projects.
