2016 International Engineering Award!

EOR has been selected by the International Federation of Consulting Engineers (FIDIC) for an Engineering Award of Merit.

As one of the top 21 engineering projects in the world identified by the FIDIC, EOR received an Engineering Award of Merit for its innovative LID-Approach to Green Infrastructure and Stormwater Management.

EOR is 1 of only 4 USA engineering firms represented and the smallest engineering firm to be so honored. [See 2016 FIDIC Award Recipients ]

Senior Project Engineer & Founding Firm Principal, Brett H. Emmons attended the FIDIC International Infrastructure Conference and Awards Ceremony in Marrakesh, Morocco this fall.

"Designing a City for Zero Stormwater Discharge"

[Listen to the MPRnews audio here, See MPRnews article here]

EOR developed a unique stormwater management plan and has implemented a series of Low Impact Development (LID) designs for the City of Inver Grove Heights to address a challenging, landlocked area that formed an obstacle to the community's growth. This LID-led approach greatly reduced infrastructure cost, improved community amenities (such as green and open spaces), and helped reduce pollution impacts on the area's lakes and adjacent Mississippi River.

This project, in conjunction with the City of Inver Grove Heights, MN was developed by a dedicated team of professionals that also included:
- Hoisington Koegler Group Inc. (planners)
- Close Landscape Architecture (landscape architecture) - see Bob Close Studio
- McGough Companies (construction)


In 2014, nearly 10” of rain fell over a 4-day period causing flooding in other parts of the Twin Cities. Minimal runoff reached the regional infiltration basins and no stormwater left the City.

The Argenta Hills Development: challenges + innovative solutions:

EOR's new and creative approach became the
first-of-its-kind in the country to rely solely on enhanced LID-type technologies to accomplish, a zero-runoff stormwater system.

EOR provided planning and ordinance development for several years, and recently the design and implementation of several zero-runoff projects.This approach saved about $30 million and resulted in a more reliable, operation-free system.

The 134 acre retail & residential development used a treatment-train approach, that included:
- 30+ raingardens,
- 250+ permeable asphalt parking stalls,
- permeable paver intersections,
- infiltration basins and a biofiltration swale
