Top Reasons Why Property Floods Occur – Part 2

Last week, we shared the top two reasons flooding occurs in developed areas. Today, we continue the list with three more reasons.

3) Property Elevation

If you’ve noticed that your property floods more than it seems reasonable, even when the rain is not legendary and the riverbeds have a safe amount of dry bank, this could be a critical flaw in elevation planning. Essentially, a property should never be ‘downhill’ if you want to prevent flooding – even in hillside areas where some locations are inevitably downhill from others.

The way to do this is to build your grounds as a small flood basin with a drainage plan so that even if water flows downhill toward your building, it never pools up around the foundation, in the basement, or above your threshold. If you’re experiencing regular flooding, strategic landscaping may be the answer.

4) Urban Drainage Basins

Unfortunately, sometimes a change in local flooding tendencies is the result of irresponsible parking lot or venue planning. Urban drainage basins are areas that are left unpaved so that water can sink into the ground. However, if a venue paves over a drainage basin, or even part of one, for a parking lot then it can cause more flooding in the local areas that were previously safe from flooding.

Areas that are suffering from urban flooding problems due to paving need new plans for runoff and water absorption or diversion.

5) Broken Dams

Finally, be aware if your region was created by building a dam and drying out what were previously wetlands. This is particularly common near the shoreline and traditionally swampy or marshy areas (hello, Florida!). In these cases, flooding can occur when a large or small dam breaks and can’t be immediately repaired. Because many of today’s dams are aging, dam breaks are not uncommon and anyone who lives near a dam should consider at least knowing where to get flood remediation supplies like sandbags.

If your property has experienced flooding or you want to make sure that it does not, look into the landscaping, runoff, and drainage systems in place. You will want your landscaping to slope away from the building in all directions and contour to guide water safely away from your foundation and anyone else’s.
