Lake Whitehurst is a drowned estuary impounded in the early 1900s to create a drinking water reservoir for the City of Norfolk. Since the initial impoundment, the dam spillway has been modified to include notches and removable stop logs to seasonally control the normal pool elevation of the lake. Today, Lake Whitehurst covers an area […]
As municipalities confront the escalating challenges posed by climate change, strategic planning emerges as a crucial tool for fostering adaptation and resilience. In the past decade, reputable sources have projected variations in rainfall, sea level rise, and other anticipated climate change impacts. Local planners are now eager to incorporate these projections into local models to […]
The Hampton Roads Sanitation District (HRSD) provides wastewater services to 1.7 million people in southeast Virginia. The low topography, regional climatology, and coastal proximity of this region make many of HRSD’s pumping and treatment facilities vulnerable to flooding. This vulnerability is increasing with climate change and rising sea levels, increased storm surge, and greater rainfall […]
Urban stormwater management represents one of the most pervasive, significant environmental issues in the U.S. Due to shifts in the frequency and intensity of rainfall events, increasing economic development, and urbanization, cities and communities are faced with growing challenges around flood risk management and protection of property, public health, and safety. With advancements in technology, […]
The National Flood Insurance Program is phasing in a new way of measuring flood risk and calculating flood insurance premiums. Here’s a hint-we will no longer be using Flood Insurance Rate Maps to rate flood insurance policies! Join us for an overview of our new methodology, new rating variables, and what it means to NFIP […]
Recent history has demonstrated how quickly and unexpectedly conditions and priorities can change, which can quickly diminish the value of a conventional stormwater master plan. New and increasingly accessible approaches including 2D modeling, dynamic dashboards, and interactive visualizations provide increased utility and longevity of master planning efforts, better addressing stormwater challenges and communicating those solutions […]
The Lynnhaven River in the City of Virginia Beach is a waterway of national significance and was once renowned for its oyster population. For decades, the river had been impaired to a point where oysters and other fish caught could not be consumed. Through regional efforts, the river is rebounding. The LRBER Project is an […]
The Ashville Park Drainage Improvements Phase I is the first of a comprehensive, multi-phased strategy aimed at mitigating recurrent tidal and storm flooding in the Ashville Park Neighborhood in Virginia Beach, Virginia. Addressing the challenges posed by unpredictable wind-driven tides, which operate independently of normal lunar tides, is crucial. These tidal events significantly reduce the […]
While stormwater ponds are an effective best management practice for reducing stormwater runoff, often the algae that accumulates in them is considered a nuisance. Traditional treatments such as copper-based algaecides are not environmentally friendly, and other methods of removal can be costly and time consuming. Additionally, algae has a high capacity to remove contaminants from […]
The Virginia Lakes and Watershed Association is a volunteer organization and its mission is to provide education on water resources in Virginia.
