Water Drainage and Erosion Control
Yard drainage is the single most important component of quality landscape installation.
Prevent Flood Damage
Poor yard drainage can lead to flooding and ultimately ruin property and landscaping.
It is much easier and less costly to improve landscape drainage problems during
the initial design and construction phases of a project rather than afterwards.
Yard drainage solutions and modifications can be accomplished by using either surface water drainage, or below ground drainage, or both.
Surface Water Drainage
Surface drainage systems pull excess water from hardscapes, planting beds and areas
where water tends to collect and provides a path on the surface for the water to
Catch Basins collect the above-ground runoff at the edge of landscape features (patios,
lawns, driveways, etc.) and carry the water to a collection point via an underground
drain pipe that doesn't impact your garden.
Dry Streambeds or shallow swales that can be planted are an aesthetically pleasing
as well as functional addition to your landscape. The streambed creates a natural
path for the water, containing it and preventing erosion. Dry streambeds and swales
require that your site has natural slope.
Retention Ponds are located at the lowest point on the property to collect runoff.
Below Ground Drainage
Sub-surface drains prevent erosion and protect drainage sensitive plant material
Sub-surface drainage systems remove water from a saturated yard and carry it through
a French Drain (drain rock columns) or a channel structure. The water is then moved
into a buried collection pit, drain line, or into an existing drain swale.
