DEP Home : Water : Control Stormwater In Your Yard
For questions about controlling stormwater runoff, contact DEP:
Stormwater control is required by law, and the County is held accountable through a rigorous state permit. (Learn more about the County’s NPDES Stormwater Permit). This page lists actions you can take to control stormwater from your yard that range from everyday gardening practices to installation of integrated landscaping features. All of these practices can help reduce stormwater runoff from your yard.

Disconnect Your Downspout
Landscape with Native Plants
With deeper tap roots, reduced fertilizer needs, and drought resistance, native plants are ideally suited to help control stormwater and nutrient pollution from yards. Learn more about landscaping with native plants.
RainScapes Rewards Eligible
Plant a Tree
Leaves intercept raindrops and reduce stormwater runoff. Learn how to plant and take care of trees.
Install a Rain Barrel
Use a rain barrel connected to a roof downspout to hold rooftop runoff.
Capture Rainfall in a Rain Barrel, Cistern, or Dry Well
Redirect runoff from rooftops or driveways in a storage cell.
A cistern is a water-harvesting container that is larger than a rain barrel and can be located aboveground or partially or fully underground.
A dry well is a type of infiltration system that collects stormwater in a small stone-filled pit and then allows the water to infiltrate into underlying soils. Linear dry wells can be installed alongside driveways to receive runoff. Dry wells work well in areas where space is limited and landscaping features are not desired.
Plant a Rain Garden
Instead of gardening in a raised bed, try planting special plants in a depression that has at least 2 feet of amended, permeable soil underneath. Runoff will gravitate there and then slowly drain downward.
Use Permeable Pavers
Using permeable pavers for your driveway and walkways helps to recharge groundwater and reduces runoff
RainScapes Rewards Eligible: The RainScapes Program provides rebates to defray the costs of selected landscaping techniques. Note that the program provides rebates for other measures, such as installing a green roof, as well as combinations of measures.
