Review of BMP Performance makes recommendations; Porous Pavement, Underground Detention Basin Explained
Trouble choosing the best BMP for your site? Take a look at what works and what doesn’t in The Center for Watershed Protection’s Performance Survey of Stormwater BMPs in Virginia’s James River Basin. BMP types surveyed included bioretention cells, permeable pavers, constructed wetlands, detention and retention ponds, infiltration trenches, swales, and more. At each BMP site, field teams looked for: indicators of erosion, clogging, and structural problems at the inlets and outlets; conditions directly downstream of the BMP; health of vegetative cover; signs of improper flow paths of water; maintenance issues; interesting design features; and more. The recently completed technical report describes the survey results and provides recommendations. Read more and check out the report.
Do you have questions about Porous Pavement? Bruce Ferguson has the answers. Check out some of the most common question in his recent article in the Stormwater Journal.
Controlling Runoff at the CDC: Efforts to control stormwater runoff at the urban campus of the Centers for Disease Control and Prevention led to the novel installation of an underground detention system, reported by The Stormwater Journal. Located in a highly developed urban setting within Atlanta, GA, the Roybal Campus of the Centers for Disease Control and Prevention (CDC) contains large areas of impervious surfaces that require stormwater management and detention. Constructed during the 1950s before modern requirements for controlling surface water runoff, the CDC had only minimal stormwater retention. Learn more.
Stormwater Consortium Seeks Aid — from The Reporter. The Montgomery County consortium of municipalities opposing new state stormwater regulations have divided their concerns into three categories: changes they could accept; regulations they could accept with slight alterations; and proposals so onerous that they could not be accepted. One suggestion made by a municipal engineer encourages the Pennsylvania Department of Environmental Protection (DEP) to promote more customization in its general permit applications. Find out their concerns.
