Water Resources Engineer at Water Engineering Solutions LLC

Ms. Fisher has over 30 years of experience in hydrology and hydraulics, having designed hundreds of drainage and water quality treatment facilities all along the front range of Colorado. She has also authored hundreds of drainage studies and is well versed in low impact development, groundwater investigation, and emergency flood mitigation. She was the continuing education director for Martin/Martin for over ten years, and she conducted several hundred classes for the civil department. Ms. Fisher’s current passion is helping people and solving problems, particularly for homeowners, to understand water migration and control, both on the surface and underground. She has performed dozens of site visits and water issue evaluations for conditions such as standing water, wet basements, excessive sump pump discharges, or other drainage issues.

Eliot Wong

Owner and Principal of Advanced Water Resources Engineering, LLC (AWARE)

Mr. Wong is the owner and principal engineer of Advanced Water Resources Engineering, LLC (AWARE), a water resources engineering firm that provides consultation relative to stormwater design and management, drainage, flood control, floodplain management, H&H, and permitting, as well as expert testimony on drainage and flooding litigation matters. Mr. Wong is a licensed professional engineer in Colorado with 15 years of consulting experience, and he has worked on stormwater projects in Colorado, Kansas, Missouri, South Dakota, Texas, Illinois, and New York, as well as in Peru. He has worked on nearly 40 litigation matters, of which many had a major component relative to stormwater runoff. Mr. Wong was a lead instructor for CDOT’s Transportation and Erosion Control Supervisor Certification program and frequently presents the topic of underground storage and treatment, including as the annual guest lecturer at UWRI’s 2-day detention design class. Mr. Wong enjoys spending time with his 12-month old son, the newest addition to his family.
