Drainage and Erosion Control
Whether you have a home site under construction, are restoring the land around a home you’ve lived in for many years or any conditions in between, the Going Green team has the experts to handle your drainage project. Rain events in Atlanta have been heavy during 2013 and have produced and uncovered many erosion and storm water concerns for property owners. Likewise, during periods of drought, flash flooding can create heavy erosion and topsoil loss.
Over the past several decades of community and population growth in Metro-Atlanta, we have experienced an excessive amount of storm water systems inundation and non-point source pollution. Municipalities have begun imposing regulations and building codes relating to storm water collection and runoff for new projects in an effort to best manage rainwater. As evidenced by history at Georgia’s Little Grand Canyon, or Providence Canyon, in Lumpkin, Georgia, when conservation efforts are not put into place, what begins as small wash-out areas can exacerbate into gullies, ravines and, eventually, canyons! We may not have areas as obviously severe in our neighborhoods or along visible roadways, but without consistent management efforts, small amounts of erosion and topsoil loss on residential home sites significantly add up in time.
As experienced landscape contractors, horticulturists, home owners and community members, we are aware of issues that we face through continual development and land excavation. We also understand that by educating our community and peers in ways of best management, we can be what starts as a “drop in the bucket” but will culminate to be an agent of change – for good!
Let Going Green evaluate your property and offer you solid solutions to best manage the rainwater coming from your roof as well as from the natural shed due to the lay of the land. We will develop an excellent plan of how to manage the water on your property to the maximum potential without causing undue deposition onto adjoining lands. Whether your goal is simply to reduce moisture around the foundation of the home or to install in-ground water harvesting systems, we have the team of professionals and the resources to handle your project.
With this project, our Clients in Brookhaven were facing several challenges with improving their drainage situation while working to create a useful, level backyard for their family to be able to play and enjoy the outdoors.
As properties are being redeveloped for home renovations and new construction, storm water displacement can become an issue. In this instance, the Client's backyard is at the bottom of several homes worth of water shed and is the lowest point. Because the only possible lower side of the property is bordered by an old Oak tree with tall root flares, the water simply pushes back into the yard without any possibility of a natural shed or dispersement.
Beginning the construction from an architecturally designed plan, we calculated the flow and graded the backyard by machine and moved the existing soil where we needed to push back and create a retaining wall and steps to access the backyard. During this time we installed specifically placed drain boxes and corrugated pipe in the ground which exited at the mouth of the planned bio retention pond area. Following the start of construction, we experienced several days of heavy rain.
It only took a minute to realize that the amount of water actually coming onto the property was flooding in at a much higher volume and velocity than could have been anticipated. With the developments presented during construction, we made swift provisions to prevent any site damage, recalculated the need and worked with our Clients to make a reasonable solution and a means to end the ponding situation which was occurring.
Double rows deep of EasyFlow French drains and larger sized drainage boxes and Aqua Blox under ground storage containers were installed to begin wicking the captured surface water into the ground. A dry creek bed was also installed through the rear of the property to accommodate the steady flow of water which was streaming in from the rear adjoining lot. 1500 gallons of water retention and displacement was installed in a strategic pattern each overflowing into the next as they fill in the ground and eventually filling into a basin where a 1/2 hsp sump pump was placed to manage the overflow.
Fortunately, the team had a few dry days to get the sod installed and to finish the landscaping and details. It rained again and the mulch, plants and sod held in place. The water was taken into the underground storage and overflowed to the street. The Going Green team and our clients were satisfied with the outcome and with the water dispersement rate into the soil.
It was satisfying and relieving to the Going Green team and to the Clients that the drainage and store water solutions worked well and managed the water coming onto the property. There is no longer an eroding or ponding situation in the yard and the land has become much more useful!
