Which shoreline conditions matter most?
UF/IFAS identifies wave climate, depth, salinity, slope, tides, erosion and nearby structures as key design inputs. Vegetation alone may struggle where boat wakes or wind-driven waves are strong. A natural-looking bank is not enough evidence that a planting-only treatment will succeed.
For a St. Augustine property, name the actual shoreline: creek, river, canal, inlet or Atlantic beach. Then describe the exposure at the parcel. Two properties beside the same waterbody can differ in orientation, water depth and wake exposure. Ask a qualified shoreline professional to assess those conditions before selecting plants, rock or a wall. Steps to Connecting Floridians to Living Shorelines
Compare the function of each option
| Approach | Question to resolve |
|---|---|
Native shoreline vegetation | Can the bank support plants at the relevant elevations and exposure? |
Vegetation with a sill or reef | Is additional wave reduction appropriate, and what habitat or access is affected? |
Rock revetment | Is there room for the slope and toe without filling protected habitat or blocking use? |
Retained wall with habitat features | Does the structure remain sound, and are the added features compatible with it? |
DEP describes living shorelines along a spectrum of natural and structural elements. The term alone does not tell you what will be built. Have the proposal identify each component, its purpose and who will inspect and maintain it. Resilient Florida: Living Shorelines
What should the first visit establish?
Bring a survey and previous shoreline permits. Ask the designer to mark the proposed footprint relative to the existing bank, water line, neighboring edges and any dock access. Identify the areas intended for plants and the areas where construction equipment would operate.
- Record existing habitat rather than assuming a bare-looking area has none.
- Ask how seasonal water levels and salinity affect plant choice.
- Discuss room for a planted slope and future maintenance access.
- Identify where the treatment ends and meets the neighboring shoreline.
- Ask what observation or testing is still needed before design.
These are owner preparation questions, not a do-it-yourself design method. Avoid moving material into the water to “try it out” before the project’s authorization is settled.
Does a living shoreline need environmental approval?
Natural materials do not make a project automatically exempt. DEP Northeast’s ERP program covers shoreline stabilization, and the responsible reviewer depends on the actual project. Federal review and permission to use submerged lands may also matter. Start with a marked plan showing plantings, structures, fill and temporary access.
USACE’s 2026 framework includes nationwide permits and Jacksonville regional conditions. Have the representative identify the correct authorization and any state water-quality conditions; do not copy an approval from a different project. On an Atlantic-facing site, also ask DEP about coastal construction review. Northeast District Permitting Nationwide Permit Information Coastal Construction Control Line Program
How will you know the project is working?
Agree on the project’s purpose before installation: erosion management, habitat improvement or a combination. Request a maintenance plan that explains repeat photo locations, inspections after unusual conditions, plant replacement and the response if material moves. Name who makes those decisions and whether follow-up visits are included in the quote.
Compare the full scope with the alternative being considered, including design, permits, site preparation and continuing care. We do not assign a blanket saving or promised storm performance to a St. Augustine living shoreline. The right comparison is between designs that address the same property needs.
If an existing wall is moving or losing support, start with a condition assessment. For the approval sequence, use the permit guide. Habitat enhancement can be considered alongside that work once the condition and site constraints are clear.
Agree what will be monitored after installation
UF/IFAS distinguishes several things a monitoring program can measure: shoreline position, plant survival, sediment and habitat use. Choose measures tied to your project’s goals. A green planting bed alone does not demonstrate that erosion has stopped. Living Shoreline Monitoring: evaluating environmental benefits
Before installation
Ask the designer to record the starting condition and repeat photo locations. Agree who takes follow-up measurements, how often they are reviewed and what result triggers a visit or corrective work.
After a change
Record missing plants, displaced material or a changed shoreline position from an authorized safe viewpoint. Ask the responsible professional whether the observation is expected establishment, maintenance or a design issue. Keep any corrective work within the permitted scope.
Monitoring costs, replacement plants and follow-up visits should have an owner and a budget. Ask whether these are included in the installation quote or supplied under a separate agreement.
