Back Eddy Engineering is a stormwater compliance consultancy serving Colorado's Front Range.

The name comes from a hydraulic term that anyone who's spent time near moving water will recognize. A back eddy is the calm, recirculating pocket of water that forms behind an obstacle in a stream. It's a stable spot in an otherwise chaotic flow. That's a decent description of what we try to provide for our clients: clear, steady guidance when the regulatory landscape feels anything but calm.

Our practice is built on 15 years of stormwater compliance work across the Front Range, from the northern corridor to the southern metro area. That experience spans the full life of a stormwater facility, from construction-phase compliance through permanent facility operations, MS4 program support, and enforcement response. Today our focus is the long half of that life: the decades after construction ends, when the facilities are yours to maintain. The technical tools include SWMM, HEC-RAS, and the full suite of MHFD criteria.

More importantly, years of work on the Front Range mean deep familiarity with the local jurisdictions, their reviewers, their criteria, and the way stormwater compliance actually works in practice, not just in the permit language. That local knowledge is the foundation of everything we do.

Direct Access. Honest Assessments. Plans Built for the Field.

We keep things simple. You get direct access to the engineer doing the work, not a project manager relaying messages. We respond quickly because compliance deadlines don't wait for consultants. We give honest assessments even when that means telling you something you'd rather not hear. And we write plans and reports that are meant to be used in the field, not filed in a drawer.

We're not trying to be the biggest firm on the Front Range. We're trying to be the one you trust with your stormwater work because we know the terrain, we do what we say we'll do, and we pick up the phone.
