Root barriers are also used to separate plant roots from each other. In particular, walnut trees secrete the chemical juglone which is toxic to other plants but the use of root barriers can prevent the yield reduction that would normally occur when walnut trees are alley cropped with maize as often occurs in the American Midwest .
Permeable paving systems, especially those with porous surfaces, require maintenance in order to keep the pores clear of fine aggregates as to not hinder the systems ability to infiltrate stormwater. The frequency of cleaning is again dependent on many site specific factors, such as runoff volume, neighboring sites and climate.
Retention ponds such as this one in Dunfermline, Scotland, are considered components of a sustainable drainage system. Sustainable drainage systems (also known as SuDS, [1] SUDS, [2] [3] or sustainable urban drainage systems [4]) are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure ...
It also includes additional layers, including a root barrier and drainage and irrigation systems. [49] There are several categories of green roofs, including extensive (have a growing media depth ranging from two to six inches) and intensive (have a growing media with a depth greater than six inches).

Parking lots are highly impervious.. Impervious surfaces are mainly artificial structures—such as pavements (roads, sidewalks, driveways and parking lots, as well as industrial areas such as airports, ports and logistics and distribution centres, all of which use considerable paved areas) that are covered by water-resistant materials such as asphalt, concrete, brick, stone—and rooftops.
A permeable reactive barrier (PRB), also referred to as a permeable reactive treatment zone (PRTZ), is a developing technology that has been recognized as being a cost-effective technology for in situ (at the site) groundwater remediation. PRBs are barriers which allow some—but not all—materials to pass through.
Six candidates are on the primary ballot for the District 2 Kitsap County Commissioner seat after Commissioner Charlotte Garrido decided not to run for reelection this year, after serving four ...
Use of Natural solutions: mangroves and other shoreline plants can act as barriers to flooding. Creating a Dike system: in areas with extreme floods, dikes can be integrated into the urban landscape to protect buildings. Using permeable paving: porous pavement surfaces absorb runoff in parking lots, roads and sidewalks.
