Founded in January 1997, ICON Engineering, Inc. is a locally owned and operated consulting civil engineering firm based in Centennial, Colorado. Although our areas of service include nearly all aspects of civil engineering, we are best known for our expertise in water resources. ICON specializes in complex floodplain modeling and hydrologic/hydraulic analyses, development of river and drainage master plans, stream stabilization and restoration improvements, bridge hydraulics, and design of utility and stormwater infrastructure. ICON’s capabilities also include roadway design, land development, and the development of geospatial and web-based solutions. ICON currently employs over 35 engineering staff with CAD, GIS and administrative support.

Our Mission

Our mission is to vigorously and passionately develop the best solutions for our clients which prioritize sound design for our surrounding communities. These creative solutions blend innovation with experience to find the best solution, not just “a solution.”

Our Principals

Headshot of Troy Carmann

Troy Carmann, PE, CFM


Troy is involved in the business development and day-to-day management of ICON Engineering. His civil engineering background brings a specialty in stormwater projects along the Front Range of his home state of Colorado. His design work has included stream and flood control projects across numerous tributaries in the South Platte River Basin, which have required coordination with entities such as the Army Corps of Engineers, Environmental Consultants, U.S. Fish and Wildlife Service, EPA, CDPHE, and local municipalities. Additionally, Troy is heavily involved in ICON’s GIS department, overseeing the production of countywide DFIRMs for FEMA Map Modernization projects in Colorado, Utah, South Dakota and Wyoming.

Aaron Bousselot, PE, CFM

Senior Principal | Vice President of Finance

Responsible for the finance side of business at ICON, Aaron’s responsibilities include developing project scopes and schedules, budget tracking, design support, construction management, facilitating meetings, and overall coordination with project teams and stakeholders. Aaron experience relies on his strength in civil design and project management for a wide range of stream, stormwater, parks and trails projects. He has led multi-disciplinary teams and completed a variety of successful designs including urban channel rehabilitation and natural stream systems, storm sewer systems, complex culverts, water quality and detention ponds, neighborhood and regional trails, and open space and community park improvements throughout Colorado.


Jaclyn Michaelsen, PE, CFM

Associate Principal | Senior Project Manager

Jaclyn is known for her expertise in hydraulic engineering for the master planning and design of large storm drainage projects used for flood mitigation. She specializes in hydrologic and hydraulic modeling, river analysis, dam design and analysis, floodplain delineation, stream stability, groundwater modeling and analysis, and construction observation. Her projects have included the design and analysis of high hazard dams, large storm sewer systems, water quality, passive and active flood protection measures and channel improvements, and detention facilities. Jaclyn’s focus is oriented toward projects in Northern Colorado and Wyoming.



Brian LeDoux, PE, CFM

Associate Principal | Senior Project Manager

Brian is responsible for floodplain hydrology and hydraulic design projects in central to southern Colorado. His engineering experience includes hydrologic and hydraulic analysis and floodplain delineation, as well as preliminary design through final construction plan layout for various drainage and channel improvement projects. Brian also assists in completing FEMA LOMC floodplain hydraulic study reviews, and prepares analysis of floodplains on ICON’s FEMA IDIQ contract in several states.



Tyler Rosburg, PE, CFM

Associate Principal | Senior Project Manager

Tyler leads large multi-disciplinary teams to complete challenging stream and riparian restoration projects. He specializes in hydrologic and hydraulic analysis, sediment transport modeling, and stream restoration design. Tyler has a proficiency in assessing streams and helps organizations develop protocols for evaluating stream function. Tyler enjoys focusing on design efforts for stream restoration projects that increase flood resiliency, provide sediment continuity, increase stability, create aquatic habitat, and restore natural functions.
