State DOT Survey on Resilient Erosion and Control Practices

Marketing Paragraph: Statement of Purpose: This poster explores how State DOTs approach resilient erosion and sediment control practices. It highlights the development of a survey designed to document current practices, identify gaps, and evaluate benefits of resiliency-based design methods. The poster covers methodologies for assessing ESC effectiveness and priorities for future design guidance.

Full Abstract: Complete Proposal for Your Session: This poster presents a study focused on documenting and improving resilient erosion and sediment control (ESC) practices in state Department of Transportation (DOT) projects, as part of NCHRP 24-52: Guidelines for Resilient Erosion and Sediment Control Practices. The study aims to document current state DOT practices and technologies for the resiliency-based selection and design of structural and non-structural ESC practices. The approach includes conducting a literature review, developing and distributing a survey to state DOT stormwater professionals, analyzing the responses to identify trends and gaps, and performing case example interviews.
Key survey topics include common ESC practices, observed vulnerabilities, site-specific factors influencing resilient designs, and the benefits and challenges of implementing resilient- and risk-based ESC strategies. The survey questions are designed to ensure broad applicability across DOTs and gather both quantitative data and subjective insights. Survey results are expected to be collected in early 2025, with analysis and case examples to follow shortly thereafter.
The results from the survey will guide the selection of three to five DOTs for case example interviews, prioritizing those demonstrating advanced or unique approaches to resilient ESC practices. These interviews will expand on survey insights, to provide detailed perspectives on effective methodologies, challenges, and innovative strategies. Findings from the interviews will inform subsequent project phases and contribute to the development of improved guidelines.
This research highlights the need for adaptive and climate-resistant ESC practices and aims to bridge gaps in design guidance by integrating both survey and interview findings to support state DOTs in improving ESC outcomes.
