Bamber Ridge Ravine Stabilization and Stormwater System Improvements

The Bamber Ridge and Willow Hill neighborhoods in south Rochester sit atop steep ravines that were originally used in the 1980s as part of the area’s drainage systems. Over time, these ravines began to erode, cutting into alluvial soils and shallow bedrock, creating risks for infrastructure and the environment.

To address these issues, SRF developed hydrologic models to verify flow rates and erosion potential. The team then identified multiple stabilization alternatives and presented a Concept Design Report to help City staff compare costs and select a solution.

The final construction plans for the Bamber Ridge Pond system included:

  • A combination of piped drainage and stabilized natural channels
  • Updated pond control structures for improved water quality
  • Design strategies to minimize impacts to old-growth trees
  • A low-maintenance solution designed for long-term resilience

Since completion, the area has weathered multiple large storm events without issue—demonstrating the effectiveness and durability of the improvements.
