Spring Hill itself is inland and has no Gulf-front seawalls; the seawall network is in unincorporated coastal Hernando County (Hernando Beach canal system, Bayport, and Pine Island). Seawall construction, replacement, and substantial repair require a Hernando County building permit issued by the Building Department (352) 754-4050 under the county Code and 8th Edition (2023) Florida Building Code, plus a Southwest Florida Water Management District (SWFWMD) Environmental Resource Permit (ERP), a US Army Corps of Engineers Section 10/404 permit, and a TIITF submerged lands authorization for any portion waterward of mean high water. Hernando County has no Coastal Construction Control Line (Big Bend) so no FDEP CCCL permit is required.
Seawalls are critical infrastructure on the Hernando Beach canal system, the lower Mud River, and isolated Gulf-front parcels at Bayport and Pine Island in unincorporated Hernando County. Permitting follows the standard multi-agency framework: (1) The county building permit is issued by the Hernando County Building Department ((352) 754-4050) under the Hernando County Code of Ordinances and the 8th Edition (2023) Florida Building Code; seawalls are reviewed for cap, tie-back, footing, and grading details. (2) Replacement of an existing seawall in the same footprint is typically eligible for a SWFWMD ERP exemption or self-certification under FAC 62-330.051, but new seawalls and any waterward expansion require a full Individual ERP — the SWFWMD ePermitting Help Desk for Hernando County is (352) 754-3456. (3) USACE typically issues Nationwide Permit 13 (Bank Stabilization) or Nationwide Permit 3 (Maintenance) for seawall work in navigable waters under Jacksonville District Regulatory. (4) State submerged lands consent is required from TIITF for any portion of the structure waterward of mean high water (FAC 18-21). (5) Because Hernando County is in Florida's Big Bend and has NO Coastal Construction Control Line, no FDEP CCCL permit under FS 161.053 is required even for true Gulf-front seawalls — the CCCL program covers only 25 of Florida's coastal counties and excludes Wakulla, Jefferson, Taylor, Dixie, Levy, Citrus, Hernando, and Pasco. Riprap and 'living shoreline' alternatives are increasingly favored and may qualify for streamlined Nationwide Permit 54 (Living Shoreline). Top-of-wall design elevation is driven by the FEMA Base Flood Elevation on the current effective Hernando County FIRM plus wave run-up; after Hurricane Idalia (Aug 30, 2023 — 3-4 ft surge at Hernando Beach), Hurricane Helene (Sept 26, 2024 — ~9.0 ft MHHW at Pine Island), and Hurricane Milton (Oct 9, 2024), many coastal Hernando County canal seawalls have been raised at replacement.
Building a new seawall, materially altering an existing wall, or operating in a known-failing condition without a permit violates the Hernando County Code and is enforceable through Stop Work orders, Code Enforcement notices, and Special Magistrate fines up to $500/day under FS 162.09. State and federal violations stack: SWFWMD/FDEP can assess up to $10,000/day under FS 403.121; USACE can issue cease-and-desist orders and require removal under the Rivers and Harbors Act and Clean Water Act. Unpermitted occupation of sovereign submerged lands exposes the owner to civil trespass damages to the State and possible after-the-fact lease fees plus penalties. A failing seawall that contributes to flooding of a neighboring property can also create civil liability under Florida nuisance and surface-water doctrines.
