IECA 2021 Presenter of the Year: Down Under Erosion and Sediment Control
Andrew Macleod, CPESC, CPSS – President, IECA Australasia

Crikey! How different is erosion and sediment control down under?! Don't they just do the same stuff we do in North America? Come say G'day and hear about the realities of erosion and sediment control in Australia and New Zealand. Learn about some of the challenges faced by Aussies and Kiwis in managing soil and water resources during construction projects, and see some of the innovations they've developed, especially around auto-dosed, continuous flow sediment basins.


Soils: Getting the Little Things Right
Ted Hartsig, MS CPSS – Senior Scientist, Olsson, Inc.

Soil is part of the living system that makes green infrastructure work. Critical nuances in soil design and function in green infrastructure can lead to failure if they are not understood and included in construction of stormwater management units. Every site is different and each site requires an understanding of the local and microenvironment that affects soil function, stormwater infiltration, and vegetation success. Learning of these "little" but highly important soil principles will improve your green infrastructure results and assure the long-term viability of your stormwater management design.


Approved SWPPPs Do Not Illustrate How to Prevent Sediment Discharges or Erosion
Jerald S. Fifield, CISEC – President, Hydrodynamics Inc.

A common misconception about developing SWPPPs is that many believe they demonstrates how BMPs prevent the discharge of sediment-laden runoff waters from construction sites. Such a goal is impossible to achieve due to limitations of the mitigation structures. This presentation will expose these limitations so that designers and reviewers can develop and approve practical and effective sediment and erosion control plans for contractors to implement.


Understanding and Implementing Seven Modes of Sediment Control
Dwayne L. Stenlund, M.Sc. – Transportation Prog Specialist 4, Minnesota Dept of Transportation

Sediment control is commonly understood as silt fence that operates as a sedimentation best practice. The 2020 IECA annual meeting had many excellent presentations that focused on new design tools (award paper of the year), performance testing, and utilization. This created significant interest as understanding how a highly regarded sedimentation mode of practice actually works to control sediment from upgradient exposed soil sources. However, this is only one of seven modes of sediment control that require investigation of best practice, and commensurate design for project implementation.


Deep Learning-Based Aerial Stormwater Inspections
Billur Kazaz, CPESC IT – Graduate Research Assistant, Auburn University

Drones are bringing innovative perspectives to many different professional fields but how would they impact construction stormwater inspections? Is it possible to automate inspection procedures with the use of emerging technologies? This presentation will discuss how to improve current construction stormwater inspection procedures by integrating deep learning-based object detection technology to UAS-based aerial stormwater inspections.


Revegetation Methods - What Works and Why? From Hydroseeding to Live Planting
Dylan Armour – General Manager, Trexiana Wholesale and Distribution
Damon Sump, CPESC #8824 – PNW Regional Sales Manager, Profile Products
Rosmarie Lohnes

Revegetation can be tricky! What mulch product will work the best, how much seed do I use, what species will work best for the site? Do I need to use plugs or live stakes for the best results? We'll discuss problems and solutions, as well as new best practices so you can make the right choices and get consistent results.


Anionic Polymer Based Mixing Methods for Water Quality Enhancement
Seva I. Iwinski – Vice President, Applied Polymer Systems
Kyla J. Iwinski-Wood, PhD – VP Research and Development, Applied Polymer Systems, Inc.

This presentation will cover a wide variety of introductory systems and mixing methods utilizing anionic polyacrylamide based blends. These systems are used to safely and effectively lower turbidity in the form of sediment, nutrients and heavy metals to meet water quality standards in construction, development and stormwater treatment systems. These introductory systems will include active treatment systems, semi-active treatment systems as well as passive treatment set ups.


Which are the BEST Management Practices for Construction Site Stormwater Management?
Richard A. Mclaughlin, PhD – Professor and Extension Specialist, Crop and Soil Sciences North Carolina St
Michael Perez, CPESC – Assitant Professor, Auburn University
Melanie M. McCaleb, MS, CPESC – President, NTU, Inc

Which is the best practice to use for erosion, sediment, or turbidity control? Let's see what the testing results suggest! Over the last 20 years we've looked at just about every aspect of these practices and the results will be reviewed after the audience votes on which is best. It will be a fast-paced hour with lots of opportunity to discuss and debate. Weapons will need to be checked at the door.


Erosion Control on Long Slopes
Robert R. Marshall, CPESC RLA – Erosion and Sediment Control Program Leader, Oregon Dept of Transportation

After spectacular erosion and sediment control failures on the new Hwy 20 project resulted in impacts to endangered fish species, the destruction of newly constructed bridges and the State Police escorting the project manager from the project site, I was tapped to provide erosion and sediment control design for the second effort of building this road segment. This presentation will recount the challenging project and multiple solutions to issues that occurred while working in the temperate rain forest of Oregon's Coast Range, an area with long steep slopes in a location of grand vistas and a lush and beautiful landscape.


IECA 2021 Technical Paper of the Year: Analyzing Flow Characteristics of Wattles Using a State-of-the-Art Hydraulic Flume
Blake Whitman, PhD, PE, CPESC – Assistant Professor, Middle Tennessee State University

Standard testing methodologies for evaluating wattle performance mainly focus on parameters such as sediment retention and turbidity reduction. While these parameters are certainly applicable, could additional metrics be used to quantify and evaluate in-field performance capabilities? This study aimed to develop a testing methodology for evaluating wattle performance strictly based on hydrodynamic parameters (i.e., impoundment depth and subcritical flow length) measured using a 40-foot state-of-the-art flume. Results from this study ultimately suggest that wattles can be categorized based on hydrodynamic properties and that wattle fill materials play an important roll in hydraulic performance.


Ara Tūhono Puhoi to Warkworth - Delivering world-class Connections

The Project is unique in its geological and geographical features, comprising of steep hill country to flat farmland and flood plains.


City and County of Honolulu Kaka‘ako Catch Basin Retrofits, South Street Bicycle Lane Permeable Pavement, and Sheridan Street Bioretention Area Case Studies
Jay M. Stone, P.E., BCEE, CFM, CPESC, CPSWQ, CWPPP, LEED AP – Vice President/Director of Engineering, Belt Collins Hawaii,

This presentation will feature three case studies to retrofit existing stormwater infrastructure with non-LID and LID best management practices in a tropical urban environment. The projects were completed on a fast-track design and agency outreach process due to lapsing funds. The projects are part of the municipal government to stimulate the local economy after the devastating effects of the COVID-19 pandemic.


Conducting Effective BMP Inspections
Jason Dorney, CPESC, QSD/QSP, QISP – Regional Sales Director - Appalachian Region, CORE Erosion Control Services

The primary focus of this course will be best practices for conducting required SWPPP site inspections. Lessons learned, best practices, what not to do and effective communication will be discussed in the presentation. Participants will learn about the building blocks for creating an effective inspection and consulting program for SWPPP compliance.

Robert R. Marshall, CPESC RLA

Erosion and Sediment Control Program Leader

Oregon Dept of Transportation

After stints as commercial fisherman and ski area bartender I buckled down and became a landscape architect. I worked for 25 years as a consultant for David Evans and Associates, a mid size multi disciplinary consulting firm as a Project Landscape Architect on a wide range of projects. I worked on schools, hospitals, cemeteries, parks and residences but my primary focus was streetscapes and roadsides where I designed the landscapes and erosion and sediment control.. These were not glamorous projects but big and important work that was viewed in passing by millions of travelers. In 2016 I became the Project Landscape Architect for a huge and failed project that cut through the temperate rain forest of the Oregon Coast Range. After providing a design that stabilized roadside soils in the Coast Range I was offered a position with Oregon Department of Transportation where I now sit as the Roadside Development Program leader and also the Erosion and Sediment Control Program Leader. Again, this work is not glamorous, but big and important and affords me the opportunity to work with a great team in a beautiful state.
