Stormwater Management Options to Keep Your Property Dry

culvertOne of the major issues with being in an urban area that sees a lot of rainfall is the possibility of flooding. Concrete and asphalt are not the best at absorbing rainfall. If you don’t have a good stormwater management solution installed in your commercial property, you run the risk of large swaths of it becoming ponds and lakes after a heavy rain. Fortunately for you, there are a number of stormwater management options available to meet your specific needs.

Wet and Dry Ponds

Don’t want your parking lot becoming a pond? Dig one somewhere else! Stormwater ponds are basically just ponds designed to capture and hold storm runoff so it doesn’t go places that it shouldn’t. Wet ponds, as you might have guessed, remain filled throughout the year and have additional capacity for use when need be. Dry ponds spend most of the time just looking like a low grassy area. When it rains, the pond fills to capacity for a day or three before draining.

Both pond types do more than simply prevent other parts of your commercial property from flooding. They also lessen the strain on streams and other waterways in your area, and improve water quality by helping to filter out sediment and other contaminants commonly found in rainwater. This process is called bioretention.

Tree Box Filters

If you’re looking to improve stormwater drainage and your property aesthetic at the same time, why not give tree box filters a look? These are concrete filtration systems installed belowground that have trees planted in them. The tree roots and soil filter the stormwater, after which point it’s drained out of the box into a storm drain. This improves the water quality, and helps manage flooding.

Infiltration Trenches

An infiltration trench is a shallow trench commonly found on the side of roads or parking lots. It is usually filled with gravel, and acts similar to a dry pond. During a storm, the trench will fill up with water and slowly filter it over the next several days. Water will gradually drain from the trench into a connected storm drain, free of sediment and contaminants thanks to the bioretention properties of the trench.


Sometimes the problem areas that flood on a property are just a little too removed from easy access to the rest of the municipal drainage system. In times like those, you’re probably going to need a culvert. A culvert is basically just a subterranean tunnel for water transportation, often used under roads and bridges. Digging a new culvert is often the best option for areas in the center of the property, or are located next to roads and other infrastructure that cannot be displaced to build a new drainage system.
