Muller completed a comprehensive rehabilitation of two bioretention facilities at North Park Branch Library in Richmond, Virginia. The facilities had become clogged and were no longer filtering stormwater effectively, increasing the potential for localized flooding and limiting their ability to protect water quality.
The project required the removal and off-site disposal of more than 1,400 cubic yards of unsuitable soil, sand, stone, and vegetation. Muller then rebuilt the facilities using more than 1,400 tons of filter media meeting Virginia Department of Environmental Quality specifications.
To support long-term performance, the team installed nonwoven geotextile fabric between material layers and secured it with sod staples. The surrounding areas were seeded and stabilized with erosion-control matting to protect the newly installed media and prevent erosion as vegetation became established.
Completed in November 2024, the rehabilitation prpject restored both bioretention facilities to full operational capacity. The completed improvements renewed their ability to capture, filter, and manage stormwater runoff while supporting long-term performance and regulatory compliance.
