In the past 10 years, the Virginia General Assembly has twice passed legislation incorporating “living shorelines” into the Code of Virginia as a method for stabilizing tidal shorelines in the Commonwealth. In 2020, Virginia Senate Bill 776 was passed by the General Assembly and signed by the Governor, which required the Virginia Marine Resources Commission […]
In 2018, the Maryland Transportation Authority’s (MDTA) I-895 bridge crossing Herring Run suffered scour that endangered the southbound bridge’s piers and abutments. In the late spring/early summer 2019, MDTA began corrective measures to mitigate this scour at the bridge. This included two-plus years of responding to multiple large storm events, more frequent stream bed/bridge monitoring, […]
Many factors are currently driving the need for water and wastewater utilities to take a more holistic view of the systems they operate and the water resources system in which they are embedded. Some of these factors include growth and redensification, regulatory uncertainty, climate uncertainty and vulnerability to hazards, growing social equity demands and environmental […]
Changes in intensity and frequency of temperature and precipitation provide more extreme parameters that our stressed, and often aging, infrastructure will need to overcome. These changes can mean a dramatic difference in real-time conditions within the watershed that test and potentially exceed the limits of infrastructures’ original design capacity. It is important to understand and […]
Virginia is one of the most vulnerable states when it comes to climate change. Higher sea levels and heavier rainfall events are already impacting coastal communities and the Hampton Roads region is experiencing the highest rate of sea level rise on the east coast. The coastal community has been actively developing mitigation strategies and working […]
Finding a way to implement high-level climate change planning to everyday implementation at the municipal level is a multi-faceted and, at times, frustrating issue. Creating a framework to make these plans a reality has never been more important in light of the need for more resilient stormwater infrastructure. Each time the United Nations (UN) conference […]
The City of Alexandria, VA is highly urbanized with approximately 160,000 people living in 15.7 square miles. Approximately 48% of the land area is impervious. The City currently maintains over 200 miles of storm sewer and over 560 lane miles of roadways, and includes ~24 miles of streams. The City has seen an increase in […]
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 […]
To combat the challenges of increased storm intensity and sea level rise, the City of Virginia Beach Public Works Stormwater Engineering Center (City) is currently developing a Comprehensive Stormwater Master Plan (SWMP). The City has used several stormwater models that contain all the major drainage networks to identify areas where flooding is occurring, known as […]
The Virginia Lakes and Watershed Association is a volunteer organization and its mission is to provide education on water resources in Virginia.
