Board approves Brown Lane rezone after applicant designs to 500‑year storm standard

Sarasota County commissioners unanimously approved a rezone and binding development concept for a 10.24‑acre property at 5800 Brown Lane on Feb. 25 after the applicant revised the plan to reduce impervious surface and design stormwater to a 500‑year standard.

The applicant’s engineering team presented a revised stormwater design, built into the Phillippi Creek watershed model, that compares existing watershed elevations to the post‑development condition under a 500‑year event. Matt Morris of Morris Engineering said node‑by‑node model comparisons show no measurable rise in downstream water elevations after the development is built: "After our site is built with all of our impervious area and ponds, that water elevation is still predicted to be the same," Morris said, describing modeled elevations and design adjustments.

The developer clustered lots, added cul‑de‑sacs and widened pond storage to increase on‑site retention while preserving a one‑acre wetland and significantly enlarging lake area to handle additional storm storage. The plan added sidewalks and 10‑foot buffers on east and west property lines and preserved upland buffers. County staff recommended approval after review; the Planning Commission had previously recommended approval.

Following public comment — including neighbors who expressed concerns about density and flood risk and engineers who explained the updated designs — the board adopted the ordinance approving the rezoning and binding development plan by unanimous vote.

Next steps: The applicant will proceed to final engineering and permitting consistent with the approved binding development plan and construction is expected to follow county permitting approvals.
