Drainage design and grading

Address water movement across your property with drainage design, grading, area drains, French drains, and downspout drain lines.

Quick answer

All Green Irrigation & Drainage offers drainage design and grading, area drains, French drains, and downspout exhaust drain lines. The right plan starts with where water comes from, where it collects, and where it can be directed at the property.

Describe the water pattern

Water collects in low areas after rain
Roof runoff concentrates near the house or planting
Existing grades direct water toward an unwanted area
Landscape changes need a coordinated drainage plan

Drainage services available

Drainage design and grading

Review the site and plan changes to ground levels and water paths as part of the drainage scope.

Area drains

Discuss collection points for surface water and how drain lines will carry it to an appropriate outlet.

French drains

Consider a gravel trench drainage approach for persistently wet areas, with the route and outlet planned for the site.

Downspout exhaust drain lines

Plan drain lines that carry roof runoff from downspouts toward an appropriate discharge point.

Plan the route and the outlet together

Share where water appears during and after rain, how long it remains, and any changes to the landscape or existing drains. A site review should consider ground levels, roof runoff, existing drainage, access, and a suitable outlet. The proposed design should account for nearby structures, property boundaries, and applicable local requirements.

What shapes the drainage plan

Water sources, collection areas, and existing ground levels
Soil conditions and available routes to a suitable outlet
Existing downspouts, drains, planting, and hardscape
Access for grading or trenching and restoration afterward
Property boundaries and applicable discharge requirements

Choose the approach after reviewing the site

Grading, area drains, French drains, and downspout lines address different parts of a water-management problem and may be discussed together. Agree on the route, outlet, installation scope, and maintenance access before work begins. No single drain type is the right answer for every property.

Questions about drainage design and grading

Which drainage services do you offer?

Drainage design and grading, area drains, French drains, and downspout exhaust drain lines are available. The project scope is based on a review of the property.

Do I need a French drain or an area drain?

The choice depends on the water pattern, ground levels, soil, and available outlet. Describe what happens during and after rain so the options can be assessed for your site.

Can downspout drain lines be part of the drainage plan?

Yes. Downspout exhaust drain lines are an offered service. Their route and discharge location should be considered alongside the rest of the property drainage.

What should I provide before a drainage visit?

Photos of the water pattern, its timing, known drain routes, and the property address help describe the issue. Include any planned landscape or grading changes.
