Many communities face complex challenges operating their wastewater and stormwater infrastructure, including meeting Clean Water Act (CWA) obligations under financial constraints. Communities with multiple CWA obligations for their wastewater treatment plants, sewer systems and stormwater infrastructure must prioritize their investments. In addition, they must evaluate different approaches and options for improving their systems, including gray, green and data infrastructure investments. Integrated planning is the process of systematically identifying and prioritizing actions and projects to meet CWA obligations. EPA released the Integrated Municipal Stormwater and Wastewater Planning Approach Framework to provide guidance on developing integrated plans. The framework identifies the operating principles and essential elements of an integrated plan. It also encourages communities to work with stakeholders to identify and evaluate options to respond to CWA requirements. This report focuses on the essential element of public outreach in the integrated planning process. Two case studies illustrate this process.
