Many communities in Virginia and across the country suffer from routine and often severe flooding due to a combination of riverine impacts and old, undersized stormwater collection systems. But how many communities have the opportunity to developed detailed hydrologic and hydraulic models of both systems on a watershed scale? The City of Fayetteville NC had […]
The Stormwater Management sector continues to develop and grow. With the passage of the 1987 Clean Water Act amendments, urban and suburban stormwater began to be addressed. While the legal and regulatory basis of stormwater has been around for 36 years, Phase I communities began to be permitted in 1990 and Phase II communities in […]
The City of Alexandria is a nationally designated historic district founded in 1749 with more than 900 acres of parks and dedicated public space. Like many older cities in the United States, the City is served by combined sewers, which discharge excess flows into local waterways via four permitted CSO outfalls. In April 2017, the […]
As our region continues to adapt to the effects of sea level rise, nature-based features can be an important part of the solution. Although long hailed as beneficial to coastal resilience, the actual advantages of such approaches are often inflated. For example, the use of marsh restoration as a buffer to storm surge, or as […]
Routine quarterly inspections are integral to meeting Georgia Safe Dams Program (GSDP) requirements and maintaining the long-term health of the 30 dams owned and operated by the Gwinnett County Department of Water Resources’ (GCDWR). Since 2017, Hazen and GCDWR have worked together to regularly update and upgrade the inspection program to meet GCDWR’s evolving needs […]
The South Florida Water Management District (SFWMD or District) has engaged EIP Florida Water Quality, LLC (EIP) in a performance-based contract to deliver the Lower Kissimmee Basin Stormwater Treatment Area (LKBSTA) Project (Project) on EIP-owned property in Okeechobee County to maximize removal of total phosphorus (TP) loads from priority areas of the Lake Okeechobee watershed. […]
Stormwater parks, which are public facilities that enhance communities by providing stormwater treatment and recreational opportunities in the same location, should be viewed as community infrastructure assets. These integrated systems not only treat polluted runoff from increased urbanization, but also provide improved overall aesthetics, recreational and educational opportunities, and livability where they are constructed. As […]
The South River Preserve, located in Waynesboro, Virginia, is currently listed as an EPA brownfield. The site received funding as part of the Natural Resource Damage Assessment and Restoration (NRDAR) program to remediate mercury contamination downstream of a decommissioned DuPont facility. This presentation focuses on the stormwater engineering components involved in the master planning […]
Flooding in coastal areas can occur as a result of several factors, including low-lying areas, land subsidence causing adverse slopes in storm sewer pipes, high groundwater, inadequate hydraulic carrying capacity, and the age of the stormwater system, which may have been laid in the ground before current design standards were implemented. In recent years, another […]
Risk Assessments and the use of Risk Informed Decision Making (RIDM) as it relates to evaluation of dam safety concerns have been used by many federal agencies for larger portfolios of dams for the past couple of decades. For many state, municipal, and private dam owners, however, the concept of RIDM and evaluating a dam […]
The Virginia Lakes and Watershed Association is a volunteer organization and its mission is to provide education on water resources in Virginia.
