With over 50 years of expertise in water resources planning, flood studies, and stormwater modeling, Mr. Beyerlein co-founded Clear Creek Solutions after distinguished roles in the San Franciso Bay area and Snohomish County. As a senior hydrologic engineer, he played a key role in shaping Snohomish County’s surface water management program, excelling in watershed planning, monitoring, flood control, and compliance with water quality laws. A trailblazer in engineering, Mr. Beyerlein led the development of accurate tools for analyzing land development impacts on streams, earning his firm contracts for stormwater software in California, Oregon, and Washington. Having taught stormwater modeling to over 2000 professionals, he conducts workshops on HSPF theory and application. Licensed as a professional engineer in Washington and California, certified as a professional hydrologist, and a member of the American Academy of Water Resources Engineers, Mr. Beyerlein serves clients like the U.S. EPA and the Army Corps of Engineers. Noteworthy contributions include impactful stormwater papers such as “Why Standard Stormwater Mitigation Doesn’t Work” and “Dumbing Down Hydrology.”

Ms. Cronin has eighteen years of professional experience in water rights and policy, water transactions, river restoration and conservation program design, facilitation and implementation. Currently Ms. Cronin is leading a facilitated and technical process for implementation of the bi-state Walla Walla Basin strategic plan, designing a groundwater mitigation program in southern Idaho and drafting a basin wide drought plan. Before joining Fluent, she worked for the Washington Water Trust for more than a decade, working across Washington State to implement environmental water transactions and mitigation programs with particular emphasis in the Walla Walla Basin and Puget Sound Basins. Ms. Cronin has evaluated, designed and set-up water mitigation banks to meet instream and out of stream water needs in several watersheds in Washington and in central Arizona. She also co-teaches a graduate course at Oregon State University on environmental water transactions. Ms. Cronin holds a MS in Environmental Science and Policy with Distinction from Northern Arizona University and a BA in Biology and Environmental Studies from Whitman College. Amanda is based in Seattle.

Ms. Frase’s practice focuses on representing individuals, businesses, and municipal governments throughout Washington State in matters involving the Model Toxics Control Act, Clean Water Act, Clean Air Act, as well as other federal and state environmental laws. Sara’s interests in environmental law have also naturally progressed into water systems and water rights matters for individuals, municipal governments, and port districts. Ms. Frase is also actively involved in crucial environmental litigation at both the trial and appellate court level. As an active member of the firm’s Port practice group, she enjoys having a hand in many of Washington’s port district’s environmental stewardship efforts and economic successes. Ms. Frase has even had the pleasure of being invited to speak on environmental law matters for the Washington Public Ports Association and the Northwest Environmental Business Council. Through her environmental and port district work, she has developed critical skills necessary for analyzing and triggering historical insurance coverage. Using these skills, she has aided many of the firm’s clients in insurance coverage disputes with their carriers.

Ms. O’Brien is a water rights specialist with over 14 years of experience in water resource management, specializing in water banking and water rights permitting in Washington and Alaska. Previously based in Aspect’s Yakima, Washington, office, Ms. O’Brien moved to Anchorage, Alaska, to serve as a Water Rights Permitting Manager for the Alaska Department of Natural Resources. In Washington, her work focused on planning and permitting for water bank development and transactions, water bank administration, and developing legislative reports on water management. In Alaska, she has managed a wide range of water rights permitting projects for municipal, instream flow, irrigation, and industrial purposes, along with temporary water use authorizations. Ms. O’Brien is dedicated to assisting water users in managing their water rights portfolios, planning future water use, developing water banks, and managing SEPA Environmental Impact Statements (EIS).

Ms. Ray is the Robert and Irene Sylvester assistant professor in the Department of Civil & Environmental Engineering at the University of Washington. Ms. Ray received her B.S. degree in Chemical Engineering from Washington University in St. Louis in 2009. Upon graduation, she remained at Washington University in St. Louis to obtain a M.S. degree (2010, funded by the NSF GK-12 Graduate Research Fellowship) and a Ph.D. in Energy, Environmental & Chemical Engineering (2015, funded by the EPA Students to Achieve Results (STAR) Fellowship). During her Ph.D., Ms. Ray employed surface chemistry techniques to investigate interfacial reactions of nanomaterials in water. She then moved to California as a Miller Institute Postdoctoral Research Fellow at the University of California, Berkeley in the Department of Civil and Environmental Engineering. As a postdoc, Ms. Ray developed low-cost polymer-clay composites to treat urban stormwater. At the University of Washington, she is continuing to develop and characterize new composite materials for selective contaminant removal in water sources, and for enhanced degradation of persistent contaminants. Recent work includes development of materials for selective adsorption of per- and polyfluoroalkyl substances (PFAS), PFAS destruction, and oxidation of trace organics and sorption of trace metals in wastewater and stormwater matrices. Ms. Ray has also begun investigating the fate and transport of microplastics and associated contaminants in stormwater runoff and in wastewater treatment facilities. In recognition of her novel, interdisciplinary research addressing urban water supply and sustainability, Chemical & Engineering News named her one of the “Talented 12” honorees for 2020 as well as the NSF CAREER Award in 2022.
