Tag: stormwater BMP

Stormwater management BMPs are control measures taken to mitigate changes to both quantity and quality of urban runoff caused through changes to land use. Generally BMPs focus on water quality problems caused by increased impervious surfaces from land development. BMPs are designed to reduce stormwater volume, peak flows, and/or nonpoint source pollution through evapotranspiration, infiltration, detention, and filtration or biological and chemical actions.[9] BMPs also can improve receiving-water quality by extending the duration of outflows incomparison to inflow duration (known as hydrograph extension), which dilutes the stormwater discharged into a larger volume of upstream flow.

Can It Be Too Big?

Can It Be Too Big?

A brief Forbes article this week provides a quick primer on green infrastructure. This is good—the more people understand what it is, the more likely they are to approve of it in their own communities, or at least to make informed decisions when they’re asked to vote on new stormwater

Transforming Springfield’s Mill Race Into a Community Asset

Transforming Springfield’s Mill Race Into a Community Asset

The Mill Race Stormwater Facility, one of the largest regional water quality treatment ponds in the city of Springfield, OR, includes a vegetated drainage swale, trailhead, and a multi-use path enhancing the historic Mill Race for recreational values and wildlife habitat. The project included the involvement of multi-disciplinary local agencies

Understanding Advanced Stormwater Management Techniques

Green infrastructure stormwater management is widely promoted by state and federal agencies as the proper way to control, treat and reduce stormwater runoff and its associated problems. However, there are challenges to correctly designing, constructing and maintaining these “advanced stormwater management systems.” These challenges often lead to failures or conditions

StormCon Program

StormCon 2017, the Surface Water Quality Conference & Expo, will take place August 27–31 in Bellevue, WA, at the Meydenbauer Convention Center and Hyatt Regency Hotel. The conference features more than 130 presentations in six conference tracks, plus panel discussions and a tour of local stormwater facilities.

Trees and forest systems play an important role in the water cycle by intercepting rainfall and regulating water flow to the soil for more efficient stormwater infiltration. Traditional urban development practices have reduced the function of these systems by eliminating the vertical structure (tree canopy cover), removing existing ground cover

An Integrated Watershed Assessment Tool for Restoration

An Integrated Watershed Assessment Tool for Restoration

The importance of water and water quality has become a heightened global concern as human populations grow, industrial and agricultural activities expand, impervious surfaces increase, and climate change threatens. The adoption of the federal Clean Water Act and related state and regional environmental regulations imposed on municipal separate storm sewer
