Stormwater Restoration
After a severe thunderstorm in late July caused heavy erosion and redirected the stream bed, RemacUSA, Inc. was called in to restore the natural flow, replace damaged infrastructure, and protect neighboring properties from future flood risks.

1. Remove and replace damaged stormwater pipes
2. Rebuild the eroded stream pathway
3. Stabilize banks and prevent further erosion
The July 2025 thunderstorm caused excessive water velocity that deeply scoured the stream banks, displaced boulders, and widened the channel by several feet, damaging nearby lawns and undermining footpath access.
REMAC used topographic assessment tools and pre-storm maps to realign the stream to its original path. Erosion-resistant fill was compacted in layers to rebuild the banks, and geotextile fabric was used below the riprap to prevent future undermining.
1. Concrete & Debris
2. Excavated Soil & Boulders
REMAC restored the stream to a controlled, naturalized flow, protecting nearby homes from future erosion while enhancing the overall appearance of the landscape. The upgraded piping now accommodates greater water volume, and the reinforced banks provide long-term durability.
The homeowners’ association commended REMAC for swift response, respectful coordination with neighbors, and leaving the site cleaner than it was before.
STORMWATER REMEDIATION & STREAM REALIGNMENT
Excavated and regraded the eroded stream bed to reestablish a stable flow path
Reconstructed and compacted stream banks using clean fill and natural contours to resist future washouts
PIPE REMOVAL & REPLACEMENT
Safely removed collapsed or undersized storm pipes contributing to flow restrictions
Installed larger, corrosion-resistant HDPE piping to handle future high-volume runoff events
EROSION & SEDIMENT CONTROL (ESC)
Installed silt fencing and check dams prior to ground disturbance
Deployed riprap and turf reinforcement matting post-restoration to stabilize stream edges
SITE ACCESS & NEIGHBORHOOD COORDINATION
Excavated and regraded the eroded stream bed to reestablish a stable flow path
Reconstructed and compacted stream banks using clean fill and natural contours to resist future washouts
