Observe the problem before choosing a product

From a safe location, photograph the yard during and after rain. Take a wide view that shows the house and surrounding surfaces, then closer views of pooling and visible flow. Record roughly when water appears, how long it remains, and whether the same area stays wet during dry weather. Do not enter moving water or open drainage structures to investigate.

Separate observations from guesses. Water near a patio might be related to surface levels, runoff arriving from elsewhere, irrigation, or a blocked collection point. Note roof downspouts, existing drains, and recent landscape changes. This information gives the person assessing the site a better starting point than a request for a specific pipe.

When surface grading belongs in the conversation

A grading correction changes the shape of the ground so surface water follows a considered route. It may be worth evaluating where an uneven area traps runoff or where new landscape work has interrupted an existing path. However, available space, nearby structures, and neighboring properties can limit what is appropriate.

Review the whole route, including its destination, before changing levels. Raising one planting bed or lowering one edge can affect other areas. Where paving or retaining structures are involved, drainage decisions should be coordinated with those elements. The goal is a complete approach, not a dry patch that creates a new problem farther along.

What surface collection can and cannot do

Surface inlets and channels collect water that reaches them. They can be considered around hardscape where water needs an organized collection point, but their effectiveness depends on the surrounding levels and the rest of the system. A grate placed above the lowest area will not fix the underlying mismatch by itself.

Discuss cleaning access, leaf litter, sediment, and how the collection system will be inspected over time. Existing systems may need condition assessment before anyone proposes extending them. Avoid assuming a visible pipe is usable or that a connection is authorized. The proposed discharge arrangement needs to be established for the actual property.

As a planning comparison, grading changes the surface route, an inlet collects water arriving at a point, a subsurface drain addresses appropriate below-ground conditions, and a permeable landscape approach changes how an area receives water. These options can work together; this comparison does not diagnose which one a particular yard needs.

Why a French drain is not the default answer

Subsurface drainage addresses water below the surface in circumstances where that approach suits the site. It is different from collecting runoff moving across a patio. Soil, groundwater conditions, nearby foundations, and a suitable discharge arrangement affect whether a subsurface system belongs in the solution.

A generic trench detail cannot resolve those questions. Ask the evaluator to explain the suspected source of the water and why the proposed system addresses it. If the problem suggests a building, structural, or complex subsurface concern, the next step may involve a qualified specialist before landscape construction is scoped.

Consider permeable areas as part of the landscape

Planted areas and appropriately designed permeable surfaces may be part of a broader water-management approach. Their suitability depends on the soil and site; replacing a solid surface with gravel does not automatically create a drainage system. The relationship to structures and the ability to maintain the surface deserve attention.

For a patio remodel, discuss drainage alongside furniture layout, door transitions, and planting rather than leaving it until materials are selected. City stormwater guidance and Water Authority landscape resources provide useful background, linked below. Confirm the requirements for your jurisdiction and avoid directing runoff toward a neighbor or assuming the street is an acceptable outlet.

Your next-step checklist

  • Gather wide and close photographs showing water paths without entering unsafe areas.
  • Record rain timing, persistence of pooling, and dry-weather wet spots.
  • Mark known drains, downspouts, irrigation, and recent changes.
  • Explain what needs protection and which landscape changes you are considering.
  • Request a site-specific explanation of collection, conveyance, destination, and maintenance.
