Evaluating the benefits of Continuous Monitoring and Adaptive Control (CMAC) technology

Focus Area

Water Quality/Wetlands


Natural Resources







Research Idea Scope

Post Construction Best Management Practices (BMPs) are required by DOT NPDES Permits and applicable Total Maximum Daily Loads (TMDLs) to reduce pollutant loadings that are discharged into receiving waters from highway runoff. In addition, NPDES permits or other regulatory drivers require long-term operation & maintenance (O&M) to ensure functionality of the BMPs. With these growing challenges, Continuous Monitoring and Adaptive Control (CMAC) technology could provide DOTs with a more effective and efficient solution to manage BMPs and drainage infrastructure, improve water quality, alleviate flooding, and reduce O&M requirements.

Urgency and Payoff

A synthesis of existing research of CMAC technology and use across the country is needed to better understand the possible advantageous of CMAC technology as it relates to benefits for drainage infrastructure performance (including pollutant removal) and O&M efficiencies. The synthesis would provide a compendium of information based on literature sources and current research to assist DOTs in modifying stormwater design and maintenance programs to meet the following objectives: ? Understand the relationship and trade-offs in a CMAC system between quantity control and water quality improvement ? Reduce cost of MS4 compliance and flood prevention through optimal application of CMAC to existing DOT stormwater infrastructure ? Identify the characteristics of typical DOT BMPs capable of providing the most beneficial CMAC retrofits ? Utilize on-site monitoring to improve and simplify ongoing stormwater management activities such as maintenance, performance reporting and data management
