County authorizes staff to pursue Phillippi Creek dredging design and permitting with WCIND; residents press to extend work to Pinecraft and oxbows

The Sarasota County Commission on March 12 authorized staff to work with the West Coast Inland Navigation District (WCIND) to design and pursue permits to extend maintenance dredging of Phillippi Creek northward to Boniva and to bring back any actions necessary for construction approval.

The action caps weeks of public appeals and technical briefings after last summer—s storms flooded homes along the creek and its oxbows. Public commenters urged the county to require dredging all the way to Pinecraft, to include the community oxbows behind Mineola and River Ridge, and to build in a plan for ongoing maintenance.

Why it matters: Phillippi Creek is a primary drainage channel for large portions of north Sarasota County. Residents and engineers told the commission that sediment and vegetation have substantially reduced the creek—s capacity and raised flood risk for adjacent neighborhoods. County staff and WCIND reported that design, surveys and permitting must be completed before a construction contract can be priced and performed.

WCIND and county update and funding issues WCIND officials have already advanced feasibility designs and bathymetry for the creek to Boniva. WCIND has a contractor under consideration for the section west of U.S. 41 to the creek mouth, and staff cited a rough order-of-magnitude construction estimate for that initial segment in the low millions ("about $2.02 to $2.5 million," staff said). The county has a survey that reaches as far north as Boniva but noted the bathymetry did not include the smaller oxbow canals behind islands; staff said those will require additional surveying and technical evaluation.

County staff told the commission that multiple funding paths are under review, including use of Community Development Block Grant for Disaster Recovery (CDBG-DR) funds; staff cautioned that federal procurement and eligibility rules for those dollars could affect how contracts are solicited and whether WCIND or the county must lead procurement.

Public comment pressed for a broader scope and faster timeline Dozens of residents described flood damage to homes on Tanglewood Drive, Mineola Drive, River Ridge and other neighborhoods. Several speakers said small changes in water level made the difference between minimal damage and major loss. Anthony Weiner told commissioners, "If the water had been a half inch higher, the whole house would have been inundated." Nadia Bowen, representing the Southgate Community Association, asked the board to "include the Southgate portion of Phillippi Creek and our Oxbow Canals into the Phillippi Creek dredging plan. Ideally, this project should extend all the way to Pinecraft."

Technical and permitting questions, and emergency options Staff briefings spelled out two near-term technical steps: (1) finalize the feasibility study and dredge-volume estimate (including a definition of planned channel width and depth) and (2) resolve options for dredge-spoil placement or disposal. Commissioners also asked staff to explore emergency permitting or limited emergency dredging to open a continuous channel to reduce immediate flood risk while the full permitting and funding work proceeds. Staff said state and federal emergency authorizations exist but added that the interaction with CDBG-DR funding requires legal and procurement review.

Board action Commissioner John Smith moved and Commissioner Maff seconded a motion authorizing staff to work with WCIND and the district—s consultant to advance design and permitting extending the Phillippi Creek project to Boniva, with staff to return to the board for any ratifications or agreements needed for execution. The motion passed unanimously.

What remains uncertain Staff did not set a construction schedule or a guaranteed start date for the Boniva-to-mouth work, and WCIND and county staff said oxbow canal work will require separate surveys and permit evaluations. The final construction cost for an extended project will depend on the dredge volume and spoil management plan. Commissioners and staff emphasized the need to balance urgency with federal procurement rules when using CDBG or disaster funds.

Next steps Staff will continue bathymetric and feasibility work, add oxbow surveys, evaluate spoil-management options, and return to the commission with recommendations for agreements, funding sources and any permits or local agreements required to move to construction.
