raSmith provided planning, design, and construction services for the Hillside Heights Kettle—a small pond surrounded by a residential development. The area has a history of flooding into a park, residential structures, and streets. raSmith was retained to evaluate the issue, conduct public involvement meetings, prepare conceptual solutions, design final solutions, and complete construction observation.
Concepts that were evaluated included: Temporary pumping, a permanent stormwater pump station, gravity pipe discharge, modification of the overtopping elevation, excavation for additional storage, watershed diversions, and flood-proofing activities for homes. Ultimately, the City decided to add storage to the depression (outside of the delineated wetland) and to utilize a temporary pump setup, when necessary.
