Stormwater Retention

The purpose of a stormwater retention feature in your landscape is to maximize the benefits of rainfall and reduce the harmful effects of runoff. When it rains, water either falls onto a permeable or impermeable surface. A permeable surface allows water to pass through. Impermeable surfaces, such as roofs or concrete driveways, do not allow water to pass, which can result in runoff. As water travels along an impermeable surface, it collects pollutants that enter storm drains and flows directly to nearby streams, ponds, and eventually, the ocean. Permeable landscapes that are built to retain and slow stormwater are great for several reasons. It helps you save money on your water bill by effectively using the rainwater to irrigate your landscape. Rain gardens also naturally treat pollutants when water is soaked up by the plants and filtered through the soil. The new Lawn-to-Garden program will provide you the knowledge and tools to design a landscape that will capture stormwater, which also helps you meet new local and regional requirements. You can choose at least one of the following stormwater elements for your landscape:

  • A rain garden/bio-swale
  • A dry creek bed
  • A berm
  • Downspout diversion into a catch basin
  • Use of 3 inches of a compost mulch mix throughout the garden area
