Record when and where water appears
- Does the change follow rain, high lagoon water, or both?
- Is water held behind the cap, at an outlet, or farther inland?
- Is soil missing or is the surface merely wet?
- Are adjacent properties or public drains involved?
Photograph from stable ground. Do not excavate behind the wall or clear an unknown outlet yourself. Give the assessor the sequence of observations.
Why a wet yard and a wall drain need different checks
Water needs an outlet
Water retained behind a wall can add pressure. The assessment should identify the source, the route and conditions at the discharge point.
Soil needs to stay in place
A drainage detail must pass water while retaining the backfill. An opening that lets soil escape can create a second problem.
Receiving water changes
A high lagoon level changes the conditions at an outlet. Record rain and visible lagoon water separately so the designer can examine both.
USACE guidance links wall drainage with pressure control and filters that retain soil. These are design principles, not instructions to drill holes in an existing wall. Drain location, filtration and any retrofit need a site-specific design.

Ask the designer to trace the route
Ask where surface and subsurface water should travel and what happens when the receiving water is high. The plan should distinguish the private drainage system from public outfalls and neighboring land. Changing the cap without checking those connections can leave important questions unanswered.
Vero Beach’s code-compliance form specifically identifies drainage changes as a reason additional plans or calculations may be needed.
Do not skip the soil-retention question
If soil is escaping, request an explanation of the path: joints, defects, drain details or another opening. Ask how a proposed repair addresses continued loss and how it will be checked. Surface fill alone does not answer that question.
| Work proposed | Check alongside it |
|---|---|
Drain modification | Retained-soil details and discharge conditions. |
Foam treatment | Void evidence, escape path and structural condition. |
Cap change | Yard grades, outlets and adjoining elevations. |
Public drainage work | Ownership, approved scope and private-wall responsibility. |
Give the assessor a sequence they can investigate
A useful observation log
“The low area stayed wet the morning after rain; water was visible at the outlet that afternoon; a new depression appeared near the same joint.” Add the dates and photographs from safe ground.
This is more useful than labeling the problem “bad drainage.” It preserves the sequence without assuming whether the cause is runoff, groundwater, an outlet condition or soil loss. Keep observations of nearby public drains separate from the private wall.
Keep private work and public records separate
Use the city or county project record to ask informed questions about nearby drainage work. A public drainage project does not diagnose your wall or promise a repair to it. Ask the appropriate office which assets it maintains.
Bring the findings to the assessment and save the proposed drainage detail with your property records.
