Cocoa council orders systemwide study for Indian River Drive flooding after residents cite worsening tides and groundwater

The Cocoa City Council on June 9 unanimously directed staff to hire a specialized engineering firm to study flooding along a problematic stretch of North Indian River Drive near Dixon Boulevard.

Engineering staff presented a corridor assessment that framed the problem as three interacting drivers: rising groundwater, extreme rainfall runoff and river/lagoon backflow during high tides or surge. "Flooding along Indian River Drive is not being driven by a single source," the staff presentation said, urging a basin‑scale study to prioritize solutions and avoid creating unintended consequences by protecting only some outfalls.

Staff described a toolbox of options — protective valves (duck bill and inline), baffle boxes for water‑quality treatment, riprap and concrete gravity walls for shoreline hardening, and targeted stabilization at low points — and warned that partial valve installs may redirect backflow to other, unprotected outfalls. The presentation also outlined permitting pathways and noted that shoreline work will require Army Corps, state and water‑management permits.

Residents and local engineers who testified said flooding has become more frequent over recent years and raised concerns about development and maintenance. Pam Coiner, who lives on South Indian Circle, told council, "The flooding never happened until they expanded US1," citing a change in local drainage behavior she said began after highway work. Civil engineer Bill Chatterton and others described pipes that are frequently underwater and urged a solution that considers the whole drainage system.

Councilmembers from multiple districts said the area requires a comprehensive approach rather than incremental fixes. Councilman Hearn asked staff to include opportunities for public‑space enhancements where feasible; staff suggested the study could identify both flood mitigation and public‑use improvements. Mayor Blake and others praised the presentation and supported staff's recommendation.

The motion approved by council directs the city manager to pursue a procurement strategy (including exploring a contract piggyback) and to return with recommended scope and budget. Staff noted Northstar Consulting Group as a firm with coastal‑drainage expertise that could be considered. Council members also discussed potential state/federal funding sources previously flagged for water‑quality/baffle‑box improvements.

What happens next: staff will prepare purchasing and budget actions for council consideration and return with an engineering contract and a final study scope and schedule.
