Building a Hydrologic and Hydraulic Foundation
Hydrology 101 – the cornerstone of all stormwater designs
• Rainfall, losses and runoff
Hydraulics 101 – understanding basic equations and concepts for better designs
• Flow conveyance, detention, retention, weirs, orifices, and culverts
H&H Modeling 101 – tools you use or should know about
• Rational method
• TR-55
• Computer models

Water Quality Design Foundation
Why we do what we do from Nationwide Urban Runoff Program (NURP)
to Stormwater Pollution Prevention Plan (SWPPP)
The science behind successful BMPs
• Which storm to use?
• Stokes Law verses Hazen’s Surface Load Theory
• Water quality capture volume (WQCV)

Stormwater Management from a Watershed Perspective
Introduction of the unified sizing criteria – Iowa Stormwater Management Manual
The 2-year, 10-year, 100-year rate control, conversion of a watershed
Incorporating over all watershed concepts to improve your project
Is peak and volume control on each site good or maybe not so good
Impact of your projects/site conditions outside your project
Case studies – two Nebraska residential developments with lots of outside flow
from adjacent watersheds

Stormwater Management for Large, Possibly Multi-Use Projects
Incorporating low impact development in the design process
Detention/retention where do I build?
Regional stormwater management verses multiple smaller stormwater components.
Using natural concepts such as rivers with floodplains in the design process
Creating habitat diversity with better engineering design
Case studies – Spring Lake Park in Omaha Nebraska as well as other examples in
Iowa, Nebraska, and South Dakota

Stormwater Management for Larger Single Use Sites
Conversion from pervious to impervious – mitigation
Pre-construction verses post construction rate and volume control challenges
Underground BMPs
Special BMP’s such as vegetated roofs and porous pavement
Aesthetic verses back of the building BMPs
Water re-use
Case studies – Various project sites in Nebraska, Iowa and South Dakota will be
used as examples of the good, the bad and the ugly

Stormwater Management for the Smaller Single Use Sites
Small development challenges
Residential neighborhoods as part of a MS4 education program
Case studies – various examples project will be highlighted

Stormwater Management for the Linear Project
Challenges of working within urban rights-of-way
Linear highway projects
Vegetation selection may be the key design component
Case studies – various example project will be highlighted

Challenges of Permitting Projects in the Midwest – are we that much different?
404 permits
Local environmental permits
Working in a floodplain

Course Title: Stormwater Management in the Midwest 2021

Delivery Method: Live Online

Course Description: This seven-hour lecture presentation examines stormwater management processes, procedures and permitting requirements unique to Midwestern states. Learners will explore basic hydrological and water quality design concepts, consider stormwater management from a watershed perspective, and evaluate design case studies for large sites, small sites and linear highway projects.

Learning Objectives:

Learning Objective 1:
Learners will be able to reference and discuss basic hydrological concepts that are fundamental to all stormwater designs. They will also be able to identify equations and computer models that can be used to produce designs that more effectively manage stormwater runoff.

Learning Objective 2:
Learners will be able to consider stormwater management from a watershed perspective, and explain how to use watershed management concepts to improve the project.

Learning Objective 3:
Learners will be able to assist in stormwater management planning on projects of various scopes and sizes, including large multi-use sites, large and small single-use sites, and highway projects.

Learning Objective 4:
Learners will be able to acquire strategies to meet and exceed environmental permitting requirements on projects in the Midwest.
