Yard drainage help for Los Gatos homes

How this usually starts

Homeowners typically start by describing the property, the visible issue, the city, timing, and any photos or previous inspections. A qualified local provider can then decide whether the project is a fit and what kind of inspection or estimate is appropriate.

This guide is intentionally conservative: it helps you prepare better questions and request help, but it does not replace a professional inspection, engineering judgment, official code guidance, or a contractor estimate.

Local context to check

• Foothill and sloped lots can concentrate runoff quickly; the provider should trace upslope water before proposing drains below the problem area.
• Retaining walls, patios, pool decks, and narrow side yards can make discharge and restoration more complicated than a flat-lawn project.
• Ask how the plan avoids shifting water to neighbors, lower portions of the property, or public areas.

Cost and scope drivers

• Slope, access, retaining-wall proximity, hand digging, erosion-control needs, and surface restoration.
• Whether the project needs catch basins, swales, French drains, downspout routing, or outlet improvements.
• Discharge route length and whether gravity drainage can work safely on the lot.

What to document before requesting help

• Photos from upslope and downslope areas during rain, including where water enters and exits the property.
• Retaining walls, drains, patios, downspouts, erosion spots, and any areas where soil is moving or saturated.
• Access constraints for equipment and any HOA, neighbor, or hillside concerns to raise during the estimate.

Questions to ask before hiring

• How does the plan handle upslope runoff and erosion risk?
• What restoration is included around landscaping, patios, walls, and irrigation?
• How will discharge be controlled so water is not concentrated in a new problem area?
