Key Biscayne workshop outlines model-driven plan: injection wells, outfall upgrades and pipe televising to address Zone 1 flooding

Jan 9, 2026

Engineers presented a detailed model showing Zone 1 (≈93.7 acres) needs a mix of measures — network reconnection, targeted groundwater injection (prelim. 35 CFS), and upgraded outfalls/pumps — and council asked staff for a do‑nothing baseline, storm-frequency analysis and a pipe‑televising cost estimate.

The full story

Engineers presented a detailed hydrologic and hydraulic analysis on Zone 1 flooding and laid out a phased approach that would combine reconnection of the existing conveyance network, targeted pressurized groundwater injection wells and upgrades to outfalls and pump stations.
