Dickerson Park Zoo Water Quality Improvements
Construction was completed on October 1, 2011. The proposed project consisted of various stormwater and water quality improvements to the Dickerson Park Zoo. These improvements included:
- A new 38-foot pedestrian bridge to replace the existing deteriorating structure.
- Five extended-detention water quality basins to remove pollutants from animal exhibits and improve water quality runoff to Pea Ridge Creek downstream.
- Excavation for two rain gardens to improve water quality and act as an educational tool for Zoo visitors.
- Construction of a new island within the existing lake to reduce bank erosion and provide an updated exhibit space for lemurs.
- Various stormwater improvements consisting of berms, swales, and pipes to reduce flooding at several locations throughout the Zoo.
