Tommy and John at AllGreen Landscape did an incredible job of designing a new driveway and entrance to our house, as well is helping us find a great pool contractor and doing all the landscaping around it and a new patio. I especially appreciate the fact that their crew has been with them for more than a decade, and they are all great guys. The whole team has worked with us closely to keep it all maintained and looking beautiful.

Expert Bioretention Facilities & Rain Garden Installation in Alexandria, VA
Transform stormwater challenges into natural assets. Bioretention facilities and rain gardens play a vital role in slowing down runoff, filtering pollutants, and preventing local flooding—but they require specialized engineering and ongoing care to prevent clogging. Whether you need a new engineered installation or routine maintenance to restore proper filtration rates, our team ensures your system meets environmental standards while enhancing your property's landscape.
AllGreen Solutions Stormwater Management designs, installs, and maintains bioretention facilities and rain gardens for residential, commercial, and municipal clients throughout Northern Virginia and Maryland. These nature-based stormwater systems capture and treat runoff at the source—reducing peak flow, removing sediment and nutrients, and recharging groundwater—while adding lasting value to your property.
Our licensed engineers and field crews handle every phase: site assessment and hydrologic analysis, soil media selection and grading, plant selection suited to the Mid-Atlantic climate, underdrain installation, and ongoing inspection and maintenance to keep filtration rates performing as designed. Over time, bioretention cells can experience clogging from fine sediment, compacted media, or invasive vegetation—issues that require professional remediation to restore function and maintain regulatory compliance.
We serve property owners, HOAs, municipalities, and commercial developers across Alexandria, Arlington, Fairfax, Bethesda, Rockville, and surrounding areas who need stormwater BMPs that perform reliably season after season. Contact AllGreen Solutions to schedule a site evaluation or maintenance visit for your bioretention facility or rain garden today.

FAQ
Bioretention Facilities & Rain Garden Installation FAQ
Common questions about bioretention facilities & rain garden installation in Alexandria, VA.
If your Alexandria property has significant impervious cover or recurring drainage issues, a bioretention system is a practical fix. Properties undergoing development or redevelopment in Alexandria may also be required to install a stormwater BMP under the City's VESMP regulations.
A rain garden is a simpler, residential-scale planted depression suited for single-family homes and townhouses in Alexandria. A bioretention facility is an engineered system with specific soil media depth, underdrain configuration, and plant criteria used in regulatory and commercial contexts.
Yes, the City of Alexandria offers Stormwater Utility Fee credits for qualifying rain gardens and bioretention filters on residential and non-residential properties. AllGreen Solutions can help you determine whether your installed system meets the City's credit criteria.
A site assessment checks soil infiltration rates and grading before any system is sized or designed. In areas of Alexandria where infiltration rates are too low, an underdrain can return filtered water to the storm drain system instead.
No, a correctly designed system drains ponded water before mosquito reproduction can occur. AllGreen Solutions sizes and grades each system so standing water clears properly after rain events.
Annual inspections are the baseline requirement for bioretention systems in Alexandria under Virginia DEQ standards. Routine tasks include checking for erosion, clearing inlet debris, replacing dead vegetation, and confirming the system drains correctly after storms.
