Near the soon to be opened and fantastic Park at the Yards<\/a>, there’s a lot of new low-impact development<\/a> infrastructure.\u00a0 These bioretention<\/a> areas should be a great example of the new kind<\/a> of both urban and environmentally sustainable infrastructure<\/a> can be.<\/p>\n

These are not ordinary tree boxes.\u00a0 Instead of draining into a standard storm sewer, these gutters drain into the tree boxes, where stormwater then naturally drains into the ground instead of into a storm sewer.\u00a0 This reduces the amount of water entering the combined storm and sanitary sewer<\/a>, and thus can help reduce the number of combined sewer overflow (CSO) events.\u00a0 Since the combined sewer system mixes storm water and regular sewage, substantial rainfall<\/a> will force the system to overflow into area rivers, dumping raw sewage mixed with stormwater directly into the Anacostia and Potomac.<\/p>\n

From the street side:<\/p>\n

Storm water will slowly absorb into the ground, aided by the various plants soils that can capture pollutants though the process of biofiltration<\/a>.\u00a0 Look at other rain gardens and tree boxes under construction – note the drainage layers of soil and gravel to be added.<\/p>\n

In this completed rain garden\/tree box, note the grade of the soil in the box, below the grade of the curb:<\/p>\n
