In Sep 2019 AllGreen removed the old timber stair/walkway in my back yard and rebuilt it with a lovely stone structure. The workmanship was outstanding -- from the careful excavation to the reinforced concrete foundation to the carefully finished stone work. Every aspect of the project was handled well -- timely scheduling, thorough cleanup each day, prompt removal of all debris, to careful raking, grading, and seeding at the end. Project Manager Kyle Jansen and foreman Carlos could not have been better to work with or more willing to be helpful. I am extremely pleased!

Expert Drainage Swales & Bioswales in Alexandria, VA
Drainage swales and bioswales move stormwater away from your property in a controlled, natural way. AllGreen Solutions Stormwater Management designs and installs both types of systems for residential and commercial properties across Alexandria, VA. A drainage swale is a graded channel that redirects runoff to a safe outlet. A bioswale adds dense vegetation and engineered soil to slow water, filter pollutants, and allow infiltration before runoff reaches local waterways. Alexandria's storm drains flow directly into streams like Four Mile Run, Holmes Run, and Cameron Run, and ultimately into the Potomac River and Chesapeake Bay. Untreated runoff carries sediment, fertilizer, and other pollutants into those waterways. A properly installed swale keeps that water on your property longer, cleans it, and releases it slowly. Alexandria also enforces grading rules that prohibit redirecting drainage onto neighboring lots. Our team accounts for those site-specific constraints during every assessment. If standing water, yard erosion, or soggy soil after rain is a recurring problem on your Alexandria property, contact AllGreen Solutions to schedule a site evaluation.
