<p>Swales are linear landscape features consisting of a drainage channel with gently sloping sides. Underground they may be filled with engineered soil and/or contain a water storage layer of coarse gravel material.  Two variations on a basic swale are recommended as low impact development strategies, although using a combination design of both may increase the benefits:<br>

<strong>Bioswales</strong> are sometimes referred to as 'dry swales', 'vegetated swales', 'water quality swales' or 'inline bioretention'. This type of structure is similar to a [[Bioretention Cells|bioretention cell]] but with a linear shape (typically >2:1 )<br>

<strong>Enhanced Grass Swales</strong> are a lower maintenance alternative, but generally have lower stormwater management potential. The enhancement over a basic grass swale is in the addition of check dams to slow surface water flow and create small temporary pools of water which can infiltrate the underlying soil.
