Geosyntec Practitioners to Present on Green Infrastructure Considerations for Healthy Watersheds

Brian Valleskey, CFM, CLP (Wisconsin), Rishab Mahajan, P.E., CFM, CPSWQ, Matthew Bardol, P.E., CFM, CPESC, D.WRE, and Dennis Dreher (Illinois) will present at the North Branch Watershed Workgroup (NBWW) virtual meeting at 1:00 p.m. CST on November 10, 2021.

Brian Valleskey is a Senior Water Resources Specialist who specializes in natural resources projects involving sediment and nutrient management. Brian works as part of a comprehensive nutrient management team focused on appropriately identifying point and nonpoint watershed-based actions to reduce surface water impacts. One of Brian's strengths is his ability to effectively translate the impacts of water quality issues to stakeholders.

Rishab Mahajan is a Project Engineer with 11 years of experience in hydrodynamic, sediment transport and water quality modeling with a focus on regulatory permits and requirements, stormwater management, surface water system assessments, total maximum daily load development and implementation, and nutrient criteria limit development. He is adept in the development and calibration of hydrodynamic and water quality models. Rishab's technical expertise at hydrologic and hydraulic modeling and stormwater design equips him to address complex situations with resourceful solutions.

Matthew Bardol is a Senior Principal Engineer based in Illinois with more than 20 years of diverse environmental and water resource engineering experience, providing a breadth of technical expertise to address the most complex water resource situations with innovative solutions.

Dennis Dreher is a Senior Consultant based in Illinois who specializes in green infrastructure and low-impact development. He was formerly the Director of Natural Resources for the Northeastern Illinois Planning Commission where he managed a variety of water and natural resource projects, with a focus on conservation design, sustainable development, stormwater and floodplain management, water quality planning, and watershed management.

NBWW is a voluntary, dues-paying organization that brings together a diverse coalition of stakeholders to work on improved water quality in the North Branch of the Chicago River watershed in a cost-effective manner to meet Illinois Environmental Protection Agency National Pollutant Discharge Elimination System permit requirements. The NBWW is committed to an approach for attaining water quality standards that focuses on stakeholder involvement, monitoring, and locally led decision-making based on sound science.


NBWW Draft NARP Workplan Overview
Presenters: Brian Valleskey and Rishab Mahajan
Brian Velleskey and Rishab Mahajan will present an overview of the Workplan, which will address two alternatives, a targeted approach Nutrient Assessment and Reduction Plan (NARP) and a full NARP (extensive evaluation) throughout the watershed.

Green Infrastructure Considerations for Healthy Watersheds
Presenters: Dennis Dreher and Matt Bardol
Green infrastructure (GI) planning and implementation opportunities exist at the watershed, community, neighborhood, and site development scales. This presentation will provide an overview of GI approaches and regional examples that can improve water quality, stabilize hydrology in the face of climate change, and preserve and restore watershed ecology and habitat.
