Drainage & Detention Engineering in Harris County
The Houston area is flat, low and wet. We design site drainage that moves storm water off your property and into the ditches and flood control channels at a rate the county will accept, and we prepare the storm water plans your permit calls for.

Who it's for
- Developers and builders whose site plan needs drainage and detention
- Commercial owners renewing a Storm Water Quality Management Plan (SWQMP)
- Contractors who need a Storm Water Pollution Prevention Plan (SWPPP) before breaking ground
- Owners of property in or near a mapped floodplain
- Owners of existing sites that flood, pond or send water onto the neighbors
What's included
- Complete site drainage and detention design
- Floodplain analysis and the mitigation it requires
- Storm Water Pollution Prevention Plans (SWPPPs) for new construction
- Storm Water Quality Management Plans, or the engineering review needed to renew one
- Drainage redesign for existing sites
How it works
-
Site review
We look at the site, where its water goes now (ditch, channel or storm sewer), and the floodplain maps.
-
Analysis
We calculate runoff before and after the project and determine what detention, if any, is needed.
-
Plans
Grading, pipes, ditches and detention, plus the SWPPP or water quality plan the permit calls for.
-
Approval
We submit to the county, city or drainage district and answer review comments until the plans are approved.
Questions about drainage improvements
Does my project need detention?
Many new developments, and projects that add paving or roof area, need detention so the site doesn’t send more water downstream than it did before. Whether yours does depends on the size of the project and which agency reviews it. We’ll tell you during the site review.
What's the difference between a SWPPP and a SWQMP?
A SWPPP (Storm Water Pollution Prevention Plan) covers construction, meaning how you keep mud and pollutants out of storm water while the site is being built. A SWQMP (Storm Water Quality Management Plan) covers the finished site and how its storm water stays clean over the long term.
Part of my property is in the floodplain. Can I still build?
Often, yes, but it usually takes a floodplain analysis and some form of mitigation, such as fill limits, elevated floors or added storage. We do that analysis and design the mitigation.
