Urban Stream Design for Interactivity

At the root of much debate surrounding ecosystem restoration projects is whether we are restoring to a condition solely for natural habitat or whether the restoration should be designed for human interaction.  Considering these perspective, as well as the future needs at the project site,  are important when determining site-specific design objectives.  Many streams throughout […]

Managing Meadows: VDOT ROW Strategies for Pollinators and Chesapeake Bay Nutrient Reductions

  As a large linear landholder, VDOT considers all parts of its right-of-way (ROW) as an asset. VDOT is assuming land stewardship responsibilities for areas outside of travel lanes and clear zones for multiple initiatives, including pollinator habitat for monarch butterflies and land cover conversion to benefit the Chesapeake Bay. VDOT is a participating stakeholder […]

Delivering Pollution Reductions, Ecological Uplift and Axillary Benefits through Stream Restoration

Stream restoration is a significant component of VDOT’s compliance with the Chesapeake Bay TMDL.  VDOT has restored over 35,000 lf of stream across 13 separate stream restorations. These projects have delivered roughly 13,000 pounds of TP, 32,000 pounds of TN and 10,000 tons of TSS reductions per year.  In terms of phosphorous and sediment, stream […]

Assessing the Pre-Dam Removal Ecological Functions of Blackwater Creek, 90 Years after the Construction of College Lake Dam: A High Hazard Dam

Aging infrastructure and impacts from climate change have recently accelerated the need for maintenance and demolition of dams across the country. The College Lake Dam in the City of Lynchburg, Virginia is a local example of the threat that aging, outdated dams can pose to public safety and river health. In the last 50 years, […]

Climate Change Adaptation Strategies for Stream Restoration and Asset Protection

Riverine ecosystems are dynamic landscape features that provide essential functions such as cycling nutrients, filtering contaminants from runoff, absorbing and gradually releasing floodwaters, maintaining fish and wildlife habitats, recharging ground water, and maintaining stream flow.   Human-induced changes to the landscape, primarily agricultural activities and urbanization are known to impact stream ecosystems.  Progress has been made […]

Effects of Tree Shelters on Tree Seedling Microclimate and Seedling Chlorophyll Production: Two-Year Results

Matured riparian forests buffer streams and rivers downslope from the effects of upslope land use by improving water quality and providing carbon sequestration. Riparian forests also protect land upstream by minimizing the impacts of flooding and high winds. Restoring riparian forests has long been considered an agricultural best management practice as large-scale agricultural use intensifies […]

The Need for Resilient Road Stream Crossings; A Call to Action

Unpredictable storm events and unreliable historic events make our current and future weather uncertain and resiliency in our built environment and our community a necessity for survival. However, we are lacking awareness about everyday transportation that could be impacted by a weather-related event. As engineers and scientists, we have a role to play in the […]
