Tag: stormwater detention pond

A detention basin or retarding basin is an excavated area installed on, or adjacent to, tributaries of rivers, streams, lakes or bays to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of a time. These basins are also called “dry ponds”, “holding ponds” or “dry detention basins” if no permanent pool of water exists. Some detention ponds are also “wet ponds” in that they are designed to permanently retain some volume of water at all times. In its basic form, a detention basin is used to manage water quantity while having a limited effectiveness in protecting water quality, unless it includes a permanent pool feature.

Changing Land Surfaces With Retaining Walls

Changing Land Surfaces With Retaining Walls

Retaining walls have become the modern-day structures of choice for us to manipulate the surfaces on which we choose to build our lives. From creating more buildable space on a site, to helping stabilize bridges, they are ubiquitous workhorses that are often easily overlooked. But sometimes they take their inspiration

Bellingham Airport Needed to Convert a Wet Pond to a Dry One

Bellingham Airport Needed to Convert a Wet Pond to a Dry One

The Bellingham International Airport, owned and operated by the Port of Bellingham Port Authority, received a grant from the FAA to convert a seven-acre wet stormwater detention pond to a dry one. It was all part of an effort to discourage waterfowl from inhabiting the pond area, which was located

Trends in Stormwater Monitoring

Trends in Stormwater Monitoring

Today’s trends in stormwater monitoring and sampling are focusing on research as well as how to better manage stormwater onsite, industry observers say. Meeting National Pollutant Discharge Elimination System (NPDES) permit requirements continues to be a focus of many stormwater monitoring efforts. Instrument manufacturers are rolling out integrated systems designed

Flow Duration–Based Stormwater Mitigation Modeling

Implementing improved engineering techniques and drastic changes in where and how land is developed and how people live and move across the land are necessary to achieve the goals in the federal Clean Water Act–to preserve, maintain, and restore the beneficial uses of our nation’s waters. –Washington State Department of

Beyond Flood Control

The Milwaukee Metropolitan Sewerage District (MMSD) and municipalities throughout southeastern Wisconsin have spent more than $300 million in recent years building flood control projects to deal with the aftermath of floods that ravaged the area in 1997 and 1998. But MMSD and the communities are not stopping there. To help

North Griffin Regional Detention Pond: Wetlands Filtration and Treatment for Nonpoint-Source Pollution Control and Abatement

The National Pollutant Discharge Elimination System (NPDES) Phase II stormwater permits now force hundreds of communities throughout the nation to look differently at how they manage their stormwater programs. These programs will undertake various approaches to reduce nonpoint-source pollutant loadings to impaired water bodies in an effort to achieve Phase

The Power of Pumps

Fred Remen knows pumps. He has to. He works with the South Florida Water Management District (SFWMD), an agency responsible for maintaining more than 2,500 miles of canals in 16 rapidly growing counties in the Sunshine State, stretching from the diverse ecosystems of the wild Everglades to the touristy Florida
