Stormwater Retrofitting
Maryland LID Retrofit Case Studies
Maryland’s diverse landscapes provide a perfect backdrop for innovative Low Impact Development (LID) projects. A standout example is the Northridge Community in Prince George’s County, which showcases how thoughtful design and strategic investments can deliver both environmental and community benefits.
Northridge Community, Prince George’s County
In 1988, the Michael T. Rose Family of Companies developed this 356-acre residential area, challenging the conventional stormwater management norms of the time[1]. By embracing early LID principles, the project incorporated features like narrower streets, bio-swales alongside curbless roads, and a robust tree preservation program to manage stormwater effectively[1].
The cost savings from skipping traditional infrastructure allowed for a $23 million reinvestment into community enhancements. These funds were used to create amenities such as a community center, a lake, and open spaces, benefiting the 855 housing units within the development[1].
Replacing the standard curb-and-gutter systems with bio-swales brought measurable hydrologic improvements. Additionally, preserving the tree canopy played a key role in reducing stormwater runoff through natural processes like interception and transpiration. This approach not only garnered several environmental and business awards but also influenced broader forest conservation efforts and encouraged the adoption of LID techniques across Maryland[1]. Northridge stands as a powerful example of how well-planned LID projects can deliver both economic and ecological gains.
Design Strategies and Site Constraints
Retrofitting Low Impact Development (LID) systems in Maryland can be a balancing act, requiring careful planning to address site-specific challenges while maximizing environmental benefits. Each project comes with its own set of hurdles, demanding creative engineering solutions to achieve effective stormwater management.
Navigating Urban and Suburban Challenges
Urban areas in Maryland often present space limitations that complicate LID retrofits. With existing buildings, parking lots, and infrastructure dominating the landscape, there’s little room for traditional bioretention systems. This forces designers to think outside the box, opting for compact, efficient solutions.
Compacted soils pose another significant challenge. Urban development often reduces the land’s natural ability to absorb water, making soil amendments or engineered media essential to support both water filtration and structural stability.
Utility conflicts are a common issue, with underground water, sewer, gas, and electrical lines often occupying the ideal spots for LID features. To work around these obstacles, design teams adjust facility depths, move systems to alternative locations, or incorporate underdrain networks to safely divert treated water around these utilities.
In some areas, like Anne Arundel County, shallow groundwater and bedrock conditions further complicate retrofits. When natural infiltration isn’t an option, filtration systems with underdrains are often used to treat stormwater before it’s directed to existing storm systems or surface waters. These site-specific challenges call for tailored LID practices that address local constraints effectively.
Selecting the Right LID Techniques
Choosing the right LID methods is critical for success and depends heavily on site conditions. For instance, bioretention areas and rain gardens are great for locations with well-draining soils and adequate space. These systems not only filter pollutants but also add aesthetic value with minimal upkeep once established.
Permeable pavement is another smart option, particularly for parking lots and low-traffic roads where space is tight. This approach maintains existing land use while offering substantial stormwater benefits. However, it requires diligent maintenance to prevent clogging and ensure long-term effectiveness.
Green roofs are ideal for urban areas with limited space, utilizing existing building structures to manage stormwater. Beyond water retention, they also provide energy savings and even create habitats. This strategy has been successfully implemented on government buildings and schools in places like Montgomery County.
For tougher conditions, like poor soils or high groundwater, constructed wetlands and sand filters prove reliable. These systems use engineered media and controlled water levels to treat stormwater consistently and remove pollutants effectively.
Amplifying Watershed Impact
Strategic placement of LID systems can significantly enhance their impact on watershed health. For example, installing LID features in headwater areas treats runoff early, reducing pollutants before they travel downstream. This proactive approach lays a solid foundation for improving overall watershed conditions.
Combining multiple LID practices along a flow path can also boost effectiveness. For instance, permeable pavement can capture initial runoff, bioretention systems can handle treatment, and constructed wetlands can polish the water before it reenters natural waterways.
Targeting specific points within a drainage network – such as tributaries – can maximize flood control and water quality improvements. Regional facilities serving multiple properties or drainage areas can further streamline maintenance and costs while incorporating advanced features like real-time monitoring to adapt to changing weather conditions.
By distributing LID retrofits strategically, Maryland can restore natural hydrology, reduce flooding, and improve water quality in its rivers and the Chesapeake Bay.

Results, Costs, and Lessons Learned
Maryland’s experience with low-impact development (LID) retrofits highlights both the benefits and challenges of implementing these systems. These projects have shown improvements in stormwater management, water quality, and even urban temperature control. At the same time, they provide important takeaways for future efforts, particularly regarding costs and maintenance.
Water Management Performance Data
LID retrofits in Maryland have delivered measurable improvements in managing water runoff and enhancing local environments. For example, community bioretention systems effectively reduced peak runoff by capturing the first wave of rainfall. Urban retrofits using permeable pavements showed better infiltration rates and lower pollutant levels when compared to traditional systems. One notable project in Montgomery County, which combined green roofs with rainwater harvesting, retained 65% of annual rainfall. This system also provided water for irrigation and helped cool the surrounding area, lowering peak summer temperatures by as much as 10°F.
These successes emphasize the practical benefits of LID systems while paving the way for evaluating their financial and maintenance aspects.
Cost Analysis and Economic Tradeoffs
Although LID retrofits often come with higher upfront costs than traditional stormwater solutions, the long-term financial and environmental returns make them worthwhile. For instance, bioretention systems in community projects not only reduced stormwater management fees but also increased property values by 3-8%. While materials like permeable pavements and green roofs are initially more expensive, they offer savings over time through lower maintenance costs and reduced energy use. Over a 15-20 year span, these systems often prove to be economically sound investments.
Maintenance Requirements and System Longevity
Maintenance plays a crucial role in ensuring the long-term success of LID systems. Bioretention systems require regular checks to assess plant health, soil quality, and drainage efficiency. During the early stages, additional care like weeding and watering is often necessary. Permeable pavements need periodic cleaning – using vacuum sweepers or pressure washers – to prevent sediment buildup. In winter, alternative deicing methods may be required to protect the pavement. Green roofs demand seasonal plant care, inspections of irrigation systems, and checks for waterproofing integrity.
In Maryland, companies like Pro Landscapes MD have demonstrated the importance of professional installation and proactive maintenance. Their expertise in areas like drainage systems, native plant choices, and sustainable design ensures that these systems perform well and last longer.
