Proper Drainage is Imperative

One of the most important aspects of any landscaping plan is ensuring that drainage of the area isn’t compromised. Proper drainage is not only imperative for structural elements, but it allows plants to stay healthy. Here are some other reasons why good drainage is so important:

  • Erosion–Without proper drainage, rainfall can cause soil to run off and carry landscaping away with it. This can lead to sloping ground and decrease the value of your property.
  • Foundation protection–Proper drainage helps maintain a constant moisture content in the soil around your foundation, which can prevent problems caused by repeated expansion-contraction cycles.
  • Pest control–Standing water can provide a breeding ground for mosquitoes and other insects.
  • Structural issues–Poor drainage can cause issues with structures in your yard, including your house, garage and patios, possibly leading to soft, wet spots in your lawn.
