Only Rain Down the Drain!
Polluted stormwater runoff is the number one cause of water pollution in Northern Virginia. Please pick up the dog stuff, recycle used motor oil, and don’t over fertilize your lawn.
If you are looking for a sustainable landscape designer or installer, consider hiring someone with the Chesapeake Bay Landscape Professional Certification. The Chesapeake Bay Landscape Professional (CBLP) Certification is a voluntary credential system for professionals who design, install, and maintain sustainable landscapes. The credential training and examination are based on a core set of standards in sustainable landscaping emphasizing stormwater best practices and conservation landscaping with native plants to benefit the environment.
Do you hire a company to take care of your lawn? Landscaping companies registered with the Virginia Department of Conservation and Recreation as Green & Clean Landscapers agree to follow landscaping practices that will reduce the amount of fertilizer runoff into our streams and rivers. Such practices include testing the soil for nutrient content before applying any fertilizer, adhering to caps on the amount of nitrogen applied to grass throughout the year, sweeping up any fertilizer that lands on hard surfaces such as sidewalks and driveways, and recycling grass clippings back into the soil. Learn more about the program and see the full list of companies on the Green & Clean registry.
If you contract with a landscaping company that uses your County-provided collection services to dispose of yard waste, you are responsible for coordinating with your contractor to ensure that any yard waste is placed in your County-provided yard waste cart, paper bags, bundles or household containers and set out for collection after 5 p.m. on the day prior to your service day. Your contractor may not set out yard waste in plastic bags for collection. Plastic isn't compostable and won't be collected. Only biodegradable paper yard waste bags will be collected.

Tree Care Resources
Concerned about your trees? The maintenance of medium to large trees is best left to qualified arborists both in terms of evaluating the need, and applying the treatment. While well executed pruning can sometimes reduce the risk of failure, poorly executed pruning can increase the risk. For a list of certified arborists in this area:
Trees fallen onto public property during a storm? For all emergencies, call 911. This includes downed power lines, fallen trees that are blocking major streets and safety issues that need immediate attention.
All trees that fall on private property become the responsibility of the owner, regardless of their original location.
Downed power lines from tree failure? Stay clear of downed power lines and downed trees in their vicinity, even if you believe that the lines are dead or have been de-energized by the power company. Lines can become re-energized as circuits are restored or come into contact with live lines. Don’t assume that lines have been de-energized just because a power company crew has visited the site.
Call Dominion Energy at 1-866-366-4357. Trees on power lines are by state law the domain of the utility company. As soon as power lines are removed from trees or made safe, the owner of the property can work to remove the tree.
