Start with exposure, available space and use
Ask a coastal professional about wave exposure, vessel activity, bottom conditions, existing habitat and the room available for a stable shoreline. Include the boat approach and the neighbor’s waterfront. The city manual notes that even rock toe protection can reduce docking space.
DEP publishes living-shoreline resources and permitting guidance. Whether a design qualifies for an exemption depends on the proposed activity; the phrase “living shoreline” does not itself confer permission.

Which site conditions change the choice?
NOAA’s shoreline comparison considers wave exposure, water levels, the shore profile and space. It presents vegetated, structural and hybrid approaches with different limits. A sheltered appearance on one calm day does not establish a design condition. NOAA shoreline comparison
- Exposure
- What wind waves, boat wakes and water-level conditions should the design address? Ask what site observations or analysis support the answer.
- Room to work
- Where would planting, grading or structural elements sit relative to the wall, property limits, dock and vessel approach? Request a plan showing the actual footprint.
- Existing support
- Does the current wall support retained ground or nearby improvements that must remain? Ask how that function would be maintained during and after the change.
- Habitat
- Which existing vegetation or bottom habitat must be protected? Ask the reviewing agency about the proposed footprint before choosing materials.
Compare what each component does
- Vegetation: what conditions support the proposed native planting and how will establishment be monitored?
- Rock or other structural elements: what footprint and support function does the design require?
- Existing wall: does it remain, need repair or require removal?
- Navigation: is the authorized dock and vessel route still usable?
- Maintenance: who monitors erosion, plant loss and movement, and what triggers professional review?
Work with the actual environmental setting
The Rookery Bay region contains mangrove and estuarine habitats, but boundaries vary. Do not promise a preserve-compatible design without reviewing the site. Protect existing mangroves and obtain agency guidance before clearing an access route.
Use the mangrove and jurisdiction guide and discuss the design with DEP South District and the appropriate city or county office.

What happens after installation?
Ask for a care and monitoring plan before comparing the finished appearance. Identify who checks the site, what they record and which findings require the designer to return.
Establishment
Who replaces failed planting, removes unwanted growth where authorized and checks whether the intended planted area is establishing? Define the responsibility and warranty conditions in the scope.
Performance
Choose repeat photo points and ask the designer what to measure. Discuss erosion, movement of structural elements, plant loss and whether the intended dock access remains usable.
Budget design, approvals, installation and ongoing care together. Ask whether a phased approach is suitable and what must be completed before a phase can function. There is no supported basis here for promising that a living shoreline will cost less than a seawall at every Marco Island property.
