Julington Creek seawall planning (Duval side)
Julington Creek forms Mandarin’s southern edge and the Duval–St. Johns county line. Which bank you are on decides which permit office you use.

Get to know your waterfront
Julington Creek runs into the St. Johns River at Mandarin’s southern edge. Census boundary data shows its lower reach as the Duval–St. Johns county line, so north-bank owners use the City of Jacksonville and south-bank owners use St. Johns County. The city’s 2026 shoreline model names Julington Creek as a likely place for living shorelines.

Creek walls and storm tides
The creek’s gauge recorded a 5.35-foot storm tide above normal high water in Irma and 2.91 feet in Nicole. The Weather Service counts minor flooding there from just 1.2 feet.

On lower-energy creek frontage, ask a designer whether a planted or hybrid edge could replace part of a wall; Florida exempts small planted living shorelines that meet its size limits. Living Shoreline Suitability Model (LSSM) report · Rule 62-330.051(12)(e), F.A.C.
The city finished stormwater work at Cormorant Branch and Loretto Road in 2023 to move flood water out faster. COJ Capital Projects layer
What could the work cost?
Living-shoreline options can be cheaper on low-energy creek frontage; ask for both options priced.
Published prices are attributed planning context from contractors’ own pages, not a measured Jacksonville average or this website’s quote. Ranges differ about five-fold between publishers; your written, itemized scope decides the real number.
