Storm Water Management & Site Planning
We offer sustainable planning, landscape design and installation services to residential and commercial architects, designers, and builders in Washington DC, Northern Virginia, and Maryland. As your site planning and sustainable landscape design partner, we can navigate county storm water management requirements for your project, leaving you free to focus on construction of the residence.
Sediment & Erosion Control Plans
As you know, the new norm for local permitting offices is: ‘No run off is good run off.’ Regulations now demand sediment and erosion control plans and/or storm water management plans for new construction when the limit of disturbance for construction is over 2500 square feet. The required size and complexity of the stormwater management plan for your building site depends on the jurisdiction in which the construction project is located.
All of this regulation is in response to the fact that many rain storms now arrive in deluges. The storm water run-off pushes sediments and fertilizers into nearby watersheds, fouling aquatic ecosystems and damaging fisheries downstream. Our homes and communities push more sediment into our rivers when high velocity rains send run off down stream, scouring water channels and sending pollution and sediment all the way to the Chesapeake.
Roadways, parking lots, sidewalks, paths and patios, can all be designed, using permeable pavements that absorb water, rather than repel it. These types of pavements re charge the ground water levels, and help reduce the levels of nitrogen and phosphorus in the Bay.
Stormwater Management Solutions
Our landscape designers work with civil engineers who do the required water retention calculations, approve, and stamp the plans so that your project will not be delayed. Our best management practices (BMPs) solutions include
- conservation landscaping
- downspout disconnection
- infiltration trenches and spreaders
- dry wells
- bio swales
- permeable paving
When designed to work together, a few of these sustainable landscape solutions can effectively absorb and retain the required amount of storm water to meet county requirements.
