We recently had the pleasure of working with River City consultants on a high profile multifaceted million dollar project in Garfield County. The timeline was extremely tight and the work complicated. River City rose to the occasion got the subs in line and finished the project ahead of schedule and under budget. As all project go there were some surprises and changes, River City brought solutions. They are very professional and friendly. I hope we get the opportunity to work with them in the future.

Careers in Grand Junction

Senior Project Engineer



Freddy’s Frozen Custard and Steakburgers construction is progressing! We look forward to the opening and trying out new food options in Grand Junction that will be available at 739 Horizon Drive and 2489 Highway 6. River City Consultants performed civil engineering and survey services for the location on Horizon Drive and engineering services for the Highway 6 location.


Chipeta Estates Subdivision in the City of Grand Junction annexation area is under construction.  The dirt contractor, CW Construction, has grubbed, cut rough grades, and installed nearly all the sewer mainline.  Not only are they moving fast and taking advantage of the unseasonably warm weather, CW is running a very clean and organized construction site!   River City Consultants performed survey and civil engineering services for this project.  Currently we are also providing construction inspection services as well.


In case you didn’t realize it, last week was national engineers week:  https://www.nspe.org/resources/partners-and-state-societies/national-engineers-week,which “Dedicated to raising public awareness of engineers’ positive contributions to quality of life…”.  We hope our clients and project owners are satisfied with the civil engineering, survey, and environmental engineering services we provide.  Stay tuned for additional news on 2017 projects that we have started!


River City is pleased to announce that we are part of all three consulting teams that were recently selected by the Grand Junction Regional Airport to provide engineering and architectural services. Congratulations to our teaming partners, Mead and Hunt, Garver, and the Blythe Group. We look forward to working together to provide surveying, land-side civil engineering, and environmental services over the next several years.


River City is proud to announce one of our projects gaining state-wide attention. We performed survey, civil engineering, and we are completing floodplain modelling and FEMA mapping services for this project: https://www.gjsentinel.com/news/articles/short-and-sweet-little-salt-wash-trail-wins-state#When:05:23:00Z “A short, but well-used section of trail that connects north and south Fruita is a recipient of a Colorado Lottery Starburst Award. The Little Salt Wash Trail is eight-tenths of a mile, but it allows non-motorized access under Interstate 70, U.S. Highway 6 and the Union Pacific railroad. On any given day, pedestrians, bicyclists and dog walkers mingle on the path that connects the city with the James M. Robb Colorado River State Park.” Congratulations to the City of Fruita for developing such a widely used public amenity!
