Synthesis of Information Related to Highway Practices. Topic 53-05. Practices for Stormwater Bioretention

Bioretention is one of the most common stormwater control measures used by municipalities, and state departments of transportation (DOTs) are increasingly being asked to use bioretention to meet federal National Pollutant Discharge Elimination System stormwater permit requirements. Some state DOTs, like Washington State DOT, have integrated aspects of bioretention into their roadway embankment, such as vegetated filter strips, compost amended vegetated filter strips, and media filter drains that treat stormwater as part of the roadway embankment. The objective of this synthesis is to document current state DOT practices for bioretention design, construction, and maintenance. Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
