5 Disaster Preparation Tips for Flooding from Heavy Rains

As a responsible landlord, property manager, or property owner, it's highly important to protect your property from water damage during powerful rain storms. Effective stormwater management is necessary to prevent flooding, erosion, and structural property damage, which can lead to expensive repairs. Check out 5 powerful disaster preparation tips and flooding solutions for harsh rain storms.

1. Maintain Clean Rain Gutters

Maintaining clean and healthy rain gutters is a necissity during powerful rain storms. When there is excess rain, the property will need its drainage systems working smoothly to minimize the risk of property damage. Consider installing additional drainage devices such as French drains and downspout extensions to improve drainage and reduce home flooding. Furthermore, install a sump pump in low areas of drive ways, car ports, or landscaping for additional protection against flooding. Another important key to stormwater management is keeping catch basins free of trash, sediment, roots, and plant debris, to allow water to smoothly flow through the drains instead of pooling around them. The installation of rock borders and/or straw wattles around drains and V-ditches can help prevent the build up of debris in drains. Keep brow ditches and V-ditches free of unnecessary debris by regularly cleaning drain outlets and weep holes of sediment. 

2. Create Swales

A swale is any depression in a landscape, existing or man-made, that redirects water drainage. A swale is natural solution to safety direct excessive water to safe territory. Consider adding swales to your property, and maximizing their presence by lining the lowest point with rocks and adding deep-rooted plants to the slopes. This overall results in slowing the water's path to the drain. Swales direct the flow of water, rather than stopping it, therefore ensure that it's channeling somewhere excess water will be released harmlessly. An area with frequent flooding should have swales directed into a dry well or deep garden bed with very good drainage and high water tolerance. To avoid costly utility charges, never have a swale draining straight off a property.

3. Install a Rain Garden

A rain garden is an excellent way to prevent disaster flooding, while simultaneously adding to the beautiful landscape of your property. When constructing your rain garden, place plants with the highest wet-soil tolerance in the center. Plants at the edge will drain rather quickly, while the middle plants remain submerged in rainwater. Furthermore, using native plants is best whenever possible. Native plants require little to no watering in between rainfalls, making your garden low-maintenance and reducing the need for harsh pesticides. Rain gardens are similar to swales, however they don't redirect water, they simply provide a place for water to safelty pool during strong rainfalls. Rain gardens will allow the excessive rain to slowly absorb back into the soil. Most rain gardens range from 50-100 square feet. Even small rain gardens can powerfully minimize flooding and runoff. 

4. Use Heavier Mulch

One overlooked solution to prevent flooding is utilizing heavier mulch. Flooding spreads light mulch chips everywhere, causing the mulch chips to clog drains and scatter throughout your yard. Consider using a hard-wood mulch, which will absorb rainfalls better, and avoid clogging drains.

5. Building Draining Driveways

Driveways are one of the biggest contributors to stormwater runoff. To reduce the risk of flooding, consider adding drainage on the sides of your concrete driveway. 

However, a more effective treatment is to eliminate the asphalt or concrete driveway completely. Gravel, spaced paving, and even grass can be used to make your driveway an asset during heavy rainfalls. Designing driveways with flooding prevention in mind will keep your clients extremely grateful. Furthermore, gravel driveways are easier to maintain, prevent flooding, and are less expensive to manage.
