Projects that involve construction activities in waterways are some of the most challenging ones that engineers and contractors face. These projects often involve obtaining permits from multiple agencies, engineering of temporary diversion measures, and development of strategies for stormwater control measures in what is often a space-constrained environment. This webinar will present guidance on these topics for non-tidal waterways including local, state and federal permitting requirements; temporary diversion methods and sizing approaches; and strategies for developing stormwater pollution prevention plans (SWPPPs) that are effective for protection of receiving waters.

Because these types of projects are typically conducted below the ordinary high water mark of waterways, permitting through the United States Army Corps of Engineers (USACE) is typically required. In addition, when projects occur within Municipal Separate Storm Sewer Systems (MS4s), local and state permits may also be required, in some cases even if the area of disturbance is less than 1 acre.

While the permitting for projects in waterways is usually more involved than for projects in upland areas, the greatest challenges of working in waterways involve effective planning, design and implementation of temporary diversions and other stormwater control measures. Andrew and Jennifer will present guidance on temporary diversion sizing that considers factors including duration of project, seasonality, consequences of exceeding diversion capacity and others.

The webinar will also include guidance on developing streamlined SWPPPs for projects in waterways. This includes work with the Denver Urban Drainage and Flood Control District (UDFCD), an organization that conducts multiple projects in waterways every year, to develop SWPPP details that address many common situations encountered when working in waterways.

Attendees of the webinar will come away with an improved understanding of the challenges of working in waterways as well as new tools and approaches to address these challenges.

Learning Objectives:

  1. Understand permitting requirements and timelines for working in waterways.
  2. Gain knowledge of temporary diversion sizing methods.
  3. Learn about effective combinations of stormwater control measures for different types of waterways construction activities.
