Flamingo Ditch Workshop: City Council Reviews Feasibility Study and Legal Obligations - June 30, 2025

The City Council of Venice held a workshop on June 30, 2025, starting at 1:00 PM, to discuss the Flamingo Ditch flood mitigation project. After setting a 10-minute public comment limit, the Council heard presentations from the city attorney on legal obligations and from Coastal Protection Engineering (CPE) on a comprehensive feasibility study. The meeting included public testimony from four residents and concluded with Council direction to pursue short-term improvements, including potential acquisition of a vacant lot for additional storage.

Public Comments & Testimony

• Luann Wood (resident of 550 West Flamingo Drive, 40-year resident): Stated that the city has maintained Flamingo Ditch for 40 years and argued that maintaining an open outfall is a simple fix. Urged immediate clearing of the ditch mouth.
• Israel Salinas (resident of 591 Flamingo Drive, chair of Flamingo Ditch Steering Committee): Presented historic photos and studies suggesting that beach renourishment projects in the 1990s contributed to sand buildup at the outfall. Called for a 100% commitment from governing authorities and continuity across future administrations.
• Loretta Elliott (resident of 601 Flamingo Drive): Quoted the legal memorandum stating the city’s obligation to maintain the ditch as part of its stormwater system. Noted lack of maintenance, overgrown vegetation, and questioned whether the city has walked the ditch. Expressed concern about a June 28 news article that appeared to prelease findings before the meeting.
• Mary Ann Robertson (resident of 703-705 Golden Beach Boulevard): Described years of flooding from common rainfall, damaging her driveway and stalling cars. She invested $20,000 of her own money for culverts and a retention wall. Noted that neighbors physically unplug the ditch during storms. Called the city’s inaction neglect.

Discussion Items

• Legal Obligations (Derek Schroth): Schroth explained that the city is not obligated to improve Flamingo Ditch but must maintain it at the current level due to historical voluntary undertakings. The city has no duty to upgrade for changed climate and is not liable for extreme weather damages. He noted that if the city makes additional improvements, it would be obligated to maintain them perpetually. He also clarified that the city can use easements for improvements but would then be responsible for maintenance.
• Feasibility Study (Coastal Protection Engineering): Tom Piero and Joe Morrow presented results of over 100 model runs covering rainfall events, storm surge events, and compound events. Key findings: Flamingo Ditch is a natural depression with a storage capacity of 276,000 cubic feet at the 5.5-foot contour; even a 1-inch rain (346,000 cf) causes street flooding. Storm surge from Hurricanes Helene (9.8 ft peak, between 50- and 100-year) and Milton (11.2 ft, near 100-year) caused severe damage. Five alternative categories were evaluated: (1) pumping systems (not effective for surge without massive, infeasible pumps), (2) raising the entire neighborhood to elevation 9 (effective up to 100-year rain and 50-year surge but extremely costly), (3) increasing storage (requires purchasing multiple properties, modest benefit), (4) upstream improvements (little effect), (5) dune/seawall (blocks surge but traps rainfall, worsening flooding). CPE recommended a combined short-term approach: raise city-owned roads, improve drainage pipes with one-way valves, and acquire a vacant lot (Lot 2) to compensate for lost storage. These measures were estimated to cost less than $5 million (in the "yellow" to "green" relative cost range) and would relieve frequent flood events, though not solve storm surge.
• Council Discussion: Council members debated the appropriate next steps. Some emphasized urgency and moral obligation to act, while others cautioned about legal liability and the need for careful evaluation. There was consensus to direct staff to pursue the short-term improvements identified by CPE, including negotiating the purchase of the vacant Lot 2 on West Flamingo Drive for additional stormwater storage and future green space. The Council also noted the importance of continued communication with residents and ongoing maintenance efforts.

Key Outcomes

• Direction to Staff: Council instructed city staff to work with CPE and pursue immediate short-term solutions, specifically: (a) design and implement road raising, drainage improvements (new pipes, grates, one-way valves), and (b) proceed with negotiations to acquire Lot 2 at West Flamingo Drive for additional flood storage.
• Grant Applications: The city has already applied for a NOAA grant ($5.9 million) and is ranked No. 2 on the Sarasota County LMS list for FEMA HMGP funding. Council supported continued pursuit of these and other grants.
• Legal Liability Consideration: Council asked staff to ensure that any actions taken do not create additional legal exposure beyond current obligations. The city attorney advised that any new improvements would require perpetual maintenance.
• Next Steps: CPE will finalize its report by late summer/early fall 2025, incorporating Council input. Staff will provide updates on Lot 2 negotiations and cost estimates for short-term projects.
