Urban runoff from gardens and hard surfaces is the #1 source of ocean pollution. In that runoff are pollutants such as:
- Pesticides, herbicides, synthetic fertilizers and sediment (soil)
- Oil, engine exhaust and brake pad dust
- Pet waste, etc.
It can run off the property during rain storms and during dry periods, with sprinklers overwatering and overshooting the landscape. In addition, the use of gas-powered equipment to mow lawns and prune and haul away over-planted and improperly spaced vegetation generates air pollutants — that eventually settle onto roofs and streets, and gets washed into waterways. This runoff also contributes to flooding of neighborhoods and erosion of stream banks.
But, gardens and hards surfaces can be beautiful, resourceful, wildlife-friendly and prevent runoff. How? Apply CPR to your garden — Conservation, Permeability and Retention © — to revive our watersheds and oceans:
- Conservation of water, energy and habitat through native plants add some climate-adapted plants, spaced for mature growth (the same applied to vegetable and fruit gardens).
- Permeability through healthy, biologically active soil, and utilizing materials for — or making a cut in — driveways, walkways and patios that allow water to percolate into the soil.
- Retention devices like rain chains, rain barrels and rain gardens retain water in the soil for the dry season or store it to water veggies, preventing it from running off of the property.
