Back Eddy Engineering is a stormwater engineering firm serving Colorado's Front Range. We work on residential, commercial, and retail sites, from the first site plan to facilities that have been in the ground for decades, and on every one we look for the stormwater approach that fits the site and get it through the agencies that have a say.

The name comes from moving water. A back eddy is the calm, recirculating pocket that forms behind a rock in a stream, a stable spot in an otherwise fast flow. That's a fair description of what we try to give clients: steady, clear direction when a drainage problem or a review process is anything but calm.

The practice is built on 15 years of stormwater engineering across the Front Range, from the northern corridor to the southern metro. That work covers the full life of a stormwater system: drainage analysis and design for new development, detention and water quality facilities, floodplain work, diagnosing facilities that don't perform, and the inspections and records that keep them in compliance afterward.

Just as important is knowing how projects actually get approved here: the city and county criteria, the reviewers who apply them, and where there's room to work when a site doesn't fit the standard answer.

Options You Understand

You talk directly with the engineers on your project, not a project manager relaying messages. We lay out the options, what each one costs, and how each one performs, then recommend the one that fits the site and the budget rather than the most elaborate one. We tell you what the site needs even when it isn't what you hoped to hear, and the drawings and reports we produce are meant to get approved and built, not filed.

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