Master the principles of urban hydrology, regulatory compliance, and low-impact development to design resilient and sustainable stormwater infrastructure.

This six‐hour presentation examines urban hydrology principles, the difference between separate and combined storm sewer systems, stormwater regulations and modeling, green stormwater infrastructure, separate storm sewer system design, and city‐scale strategic stormwater planning..
Participants will gain a robust understanding of both the theoretical foundations and the technical mechanics of drainage design. The content begins with urban hydrology basics, exploring how pavement and structures impact surface flow and time of concentration. It covers essential calculation methods, such as the Rational Method, and introduces advanced stormwater modeling software used to analyze complex basins. The course also delves into the critical regulatory frameworks, including the Clean Water Act and NPDES permitting, ensuring that designs meet federal, state, and municipal standards.
Beyond theory, this course emphasizes practical construction and design application. Learners will explore the specifics of designing separate storm sewer systems versus combined systems, selecting appropriate pipe materials like reinforced concrete and HDPE, and optimizing inlet spacing. A significant portion of the material is dedicated to Low Impact Development (LID) and green infrastructure, teaching engineers how to incorporate bio-retention, grass swales, and detention ponds to mimic natural pre-development hydrology. The session concludes with strategic planning for municipalities, addressing the challenges of aging infrastructure and funding future improvements.
