Brooke Road, a rural arterial road in the floodplain fringe of Accokeek Creek experiences frequent flooding which causes traffic disruptions, inconvenience, and hinders emergency access to the adjacent neighborhoods. This road lies at the base of a series of steep slopes and runs in parallel with the floodplain. In order to understand the causation of […]
In July 2019, a summer thunderstorm dropped up to 5.3 inches of rain in one hour over some parts of Fairfax County (up to a 1,000-year storm event), causing a reported 149 house flooding and at least $15M in damages. Studies continually show that these high intensity, short duration storms will become more frequent with […]
Nature-based solutions utilize nature, open space, and ecosystems that can provide multiple benefits to communities, including protection from natural hazards. The FEMA Hazard Mitigation Assistance (HMA) programs present a crucial opportunity to reduce the risk to communities from natural hazards, while simultaneously reducing communities’ overall reliance on Federal disaster funds. The HMA program includes three […]
Many communities across the U.S. suffer from routine and severe flooding due to a combination of riverine impacts and old, undersized stormwater collection systems, especially in urban areas. But how many communities develop detailed hydrologic and hydraulic models of both systems on a watershed scale and use these models to transform their downtown with holistic […]
Wood structures and habitat features have been used for years in the stream restoration field but have not been heavily utilized within living shoreline designs. Incorporating wood into living shorelines provides an opportunity for stabilization and shoreline protection as a more natural alternative to conventional riprap structures while being more robust than other bioengineering approaches. […]
The amount of impervious cover in residential neighborhoods tends to gradually increase over time. Property improvements on individual parcels, such as detached garages, storage sheds, and extended driveways can significantly increase the imperviousness of individual parcels. However, the associated land disturbance associated with individual property improvements often falls below the minimum threshold size to require […]
The City of Falls Church is a highly dense and urban municipality in Northern Virginia. Like many of its neighbors, flash floods in recent years have resulted in residents demanding increased focus on resiliency and flood mitigation to protect their homes from flooding. In response, the City has undergone extensive flood modeling efforts in several […]
This presentation will focus on a strategy developed to reduce flood risk in the hard-hit communities within Buchanan County, Virginia. The county has a history of devastating floods, including major events in 2020, 2021, and 2022. Topics to be addressed include: Challenges around engaging stakeholders and the public in economically disadvantaged communities that have been […]
The purpose of this presentation is to provide insight to other engineers for the design of high volume, low head stormwater pumping stations. Two case studies will be discussed that illustrate innovative solutions developed using traditional design-bid-build and alternate design-build methods. Lessons learned will be presented to provide engineers guidance when considering similar projects. The […]
The design storm is a fundamental parameter for risk and vulnerability assessment of urban infrastructure. It is traditionally determined from historic observations. There is however growing recognition that design storm calculations based on historical data may misrepresent flood risk due to future climate change. To determine if and when the design storm calculation should consider […]
The Virginia Lakes and Watershed Association is a volunteer organization and its mission is to provide education on water resources in Virginia.
