About the Owner

Maegan Nunley, P.E., CFM - President and Chief Engineer

I discovered my passion for water resources while attending college at the University of Arkansas.  Since graduating in 2012, my career has been focused on hydrology and hydraulics - a field that has become increasingly important as flood events become more common and more severe throughout the United States. My experience includes a wide variety of project types: watershed master plans, transportation and land development drainage design, flood damage reduction, dam breach analyses, floodplain modeling and mapping, municipal storm water infrastructure, conveyance and regional storage, MS4 permitting, and levee systems. 

Civil engineers are first and foremost public servants - striving to protect the world around us and design infrastructure improving quality of life today and for future generations. My goal is to provide innovative solutions improving storm water infrastructure now and in the future. 

When I'm not attempting to mitigate flooding, I can be found training or showing my two Golden Retrievers, out on the bike trail, or spending time with my husband. 

If you're wondering who my photographer is - it's my mother, Margaret Moon. Each photo was taken during one of her adventures somewhere in the great state of Arkansas.

Professional Background

August 2018 - October 2019

Senior Project Engineer, Stantec - Columbus, OH

At Stantec, I continued honing my project management and technical skills. I worked on projects such as storm water master plans, FEMA floodplain modeling, and erosion control design. My role also included personnel management, company promotion, and business development. I was privileged to represent Stantec at the 2019 Ohio Storm Water Conference, at which I presented on calibrating 2D models to Hurricane Harvey.

September 2017 - August 2018

Project Engineer, Costello, Inc. - Houston, TX

My role at Costello accelerated my professional growth and technical skills - I learned to balance performing my own work with managing that of other engineers. My projects were technically challenging, complex, and were among the first in response to Hurricane Harvey. I built my first watershed-wide unsteady HEC-RAS model, my first 2D XP-STORM model, and performed my first 2D dam breach analysis in HEC-RAS in the short span of just 10 months.

June 2014 - September 2017

Project Engineer, Dannenbaum Engineering Corporation - Houston, TX

When I joined the Dannenbaum team, I transitioned from the public sector to the private sector - two very different worlds. I am very thankful for my time at Dannenbaum, which has become invaluable. I learned the ins and outs of the consulting business, increased my technical skills, wrote my first proposals, and trained my first junior engineer. I was able to see a project through from beginning to end - from writing the approach for the statement of qualifications to producing the models and report and finally signing and sealing the finished product.

July 2012 - May 2014

Assistant County Engineer, Ellis County - Waxahachie, TX

My first job out of college will always hold a special place in my heart - I learned what it truly means to be an engineer and a public servant. My boss and mentor challenged me, taught me priceless networking skills, and gave me freedom to grow as much as I was able. My experience was broad: I managed the County's MS4 program, represented the County on a technical transportation committee at the North Central Texas Council of Governments, reviewed the drainage design plans for proposed developments, and was the Contracting Officer for the construction phase of the repair of an NRCS dam.

Academic Background

August 2008 - May 2012

University of Arkansas | Fayetteville, AR

Bachelor of Science in Civil Engineering
This place was the beginning of my engineering journey and ignited my passion for water resources. As an Arkansas native, I'm extremely proud and honored to have my name engraved on Senior Walk.
