RAINGARDENS/BIORETENTION CELLS IN POPE
As part of a separate project, DDOE/WPD has issued a grant to DC Greenworks to install raingardens (or Low Impact Development retrofits - LID) in the Pope Branch watershed. These raingardens detain water for a period of time and remove sediment, nutrients, and other pollutants from stormwater. They are designed to hold water for no longer than 24 hours and thus are not a breeding ground for mosquitos. They are planted with attractive native plants and are considered an aesthetic benefit. ECOSITE will install 4 raingardens in the watershed (2 will go in along the parkside of M Place SE). Construction is expected in spring of 2007. The picture posted (the Capitol Hill raingarden on 1st st. & C St. NE) is an example of what the M Place raingardens might look like - however without the stone.
