Synthesis of Information Related to Highway Practices. Topic 55-07. Stormwater Retrofit Programs and Practices Through Third-Party Partnerships

Many existing highways were originally constructed without stormwater control facilities, prompting several state departments of transportation (DOTs) to retrofit these highway facilities with improved treatment and flow control systems. To implement watershed-based strategies more cost effectively, some DOTs have explored partnerships with third-party entities.The objective of this Synthesis project was to document practices used by state DOTs regarding stormwater retrofit partnerships with third parties.
