Reconstruction along the MnDOT I-494 corridor between Richfield and Bloomington, Minnesota, required erosion control solutions capable of performing under some of the most demanding conditions found on active highway projects. Crews reshaped interchanges, rebuilt embankments, and stabilized steep slopes adjacent to wetlands, residential neighborhoods, and high-volume traffic lanes, all while maintaining strict compliance with state and environmental regulations. With limited work windows, aggressive grading schedules, and exposed soils vulnerable to stormwater and seasonal freeze-thaw cycles, the project demanded an erosion control system that could install quickly, hold aggressively, and protect newly seeded slopes without failure.
Challenging Site Conditions Along a Live Freeway

Grading operations exposed compacted clay loam and urban fill soils across long stretches of embankment, with slopes commonly reaching 3:1 and tightening to 2:1 in select locations. These soils retained moisture during extended wet periods yet shed runoff rapidly during intense summer storms, creating a high risk of surface erosion, rilling, and sediment transport. Passing traffic generated constant wind shear, while roadway splash-over introduced additional hydraulic stress along shoulders and slopes. Construction sequencing left little margin for corrective measures, as traffic remained active throughout the project and staging areas were constrained by barriers, pavement edges, and adjacent wetlands. Compliance with Minnesota Pollution Control Agency NPDES requirements prohibited sediment migration into nearby water resources, placing added pressure on erosion control systems to perform immediately and consistently from the moment of installation.
Approach

Nexterra's Approach

Successfully integrating the stormwater system demanded precise attention to site grading, flow management, and construction sequencing. Jen-Hill’s expertise guided the project team through these intricate challenges, ensuring stormwater objectives aligned seamlessly with construction realities. By designing an underground detention and water-quality solution, the team eliminated the need for space-consuming surface basins, unlocking every inch of usable land for leasable office space.

The system efficiently managed stormwater flows, captured sediment and debris, and maintained consistent performance even during heavy rainfall events.

By emphasizing performance, compliance, and long-term maintainability, the solution remained highly functional yet unobtrusive, preserving valuable land for office buildings and amenity areas while meeting strict regulatory and environmental standards.

This approach maximized the development’s revenue potential and demonstrated how expert guidance can turn complex stormwater challenges into practical, high-value solutions.

Outcome

The Stables at Hunt Club showcases the impact of strategic, expert stormwater planning on a complex commercial site. Jen-Hill guided Clinard Civil Contracting through every step of design and installation, ensuring regulatory compliance while preserving every square foot of usable space and maintaining the site’s visual appeal.

By combining deep technical insight with hands-on project management, the team delivered a solution on time and on budget that maximizes leasable space, maintains long-term operational performance, and turns what could have been a restrictive regulatory challenge into a showcase of efficient, high-performance infrastructure. The project stands as a clear example of how Jen-Hill transforms intricate stormwater demands into resilient, elegant solutions that protect property value and deliver enduring results.
