Municipalities in Southern California are facing an increasing amount of complexity in Municipal Separate Storm Sewer Systems (MS4) permits. Two of the more trying requirements for roadway projects that have been incorporated into permits in the region are hydromodification management (HM) and low-impact development (LID). These are being implemented as specific measurable requirements in permits and create significant challenges for municipalities. This paper analyzes the challenges that these requirements present for linear roadway projects and details the application of a stormwater model and technical feasibility analysis to identify cost-effective solutions
