Whitehurst Dredged Material Management Area – A Successful Implementation of Management Planning for the Long-Term Disposal of Dredged Material in Virginia Beach, Virginia

The City of Virginia Beach converted a man-made borrow pit, formerly referred to as Whitehurst Lake, into a Dredged Material Management Area (DMMA).  The intent was to provide a long- term disposal site for dredging projects throughout the City of Virginia Beach.  The DMMA has been used for the disposal of dredged material from various […]

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 The College Lake Dam in the City of Lynchburg, Virginia is a local example of the threat that aging, outdated dams can pose to public safety and river health.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, […]

Greening Southside Richmond at Branch’s Baptist Church

Through a grant from the Chesapeake Bay Foundation, Mr. Rissmeyer is the lead designer for retrofitting existing church parking lots at Branch’s Baptist Church in Southside Richmond to maximize water quality benefits.   The project takes advantage of underutilized and deteriorating parking lots by their removal to then make room for stormwater best management practices (BMP’s).  […]

Using an Interdisciplinary Approach to Assess Effects of Agricultural Best Management Practices on Stream Health

Despite increasing numbers of best management practices (BMPs) being installed on agricultural landscapes and billions of dollars spent on BMP programs, stream health continues to decline in Virginia due to agricultural nonpoint-source pollution. The efficacy of BMPs for restoring stream health is influenced by a complex suite of biophysical factors and is ultimately constrained by […]

Stream Restoration Site Selection – Balancing Competing Goods

As climate change, severe weather and Chesapeake Bay water quality standards increase in Virginia, stream restoration has been applied by localities, communities and environmental programs to meet ecological, mitigation and stormwater management goals. Stream restoration can be like open heart surgery to an ecosystem – intense, costly, yet potentially life-saving. Therefore, the proper selection of […]

Assessing the Condition and Vulnerability of Healthy Watersheds Across the Chesapeake Region

The Chesapeake Bay Program, through its Maintain Healthy Watersheds Goal Implementation Team, works with state partners towards a goal of maintaining the long-term health of watersheds identified as healthy by each of the individual jurisdictions. Quantitative indicators are important to assess current watershed condition, track future condition, and assess the vulnerability of healthy watersheds to […]

Finding the Elusive Sites for Hydrodynamic Separators Using Stormwater Master Plan Models

Due to the increasing cost of stormwater treatment, the City of Virginia Beach Department of Public Utilities (City) evaluated the requirements for developing a nutrient offset program. When a stormwater management facility (SWMF) can be incorporated into a site design, it typically comes at a significant cost. Creating regional SWMFs to offset the City’s facility […]

Effects of a Large Swimming Event in a Drinking Water Reservoir

A rising concern to lake and reservoir water quality is pharmaceuticals and personal care products (PPCPs), which are increasingly ubiquitous in the environment. Many studies have examined the introduction of PPCPs to freshwater ecosystems through wastewater treatment, but less is known about how direct human interactions, such as swimming, may influence PPCP concentrations. We sampled […]

Development of Finite Segment Estuarine Total Phosphorous Flux Model

The James River Treatment Plant (JRTP), Newport News, VA situates at the mouth of the Warwick River, a partially mixed estuarine tributary of the James River.  Objectives of this study are to characterize mixing, transport and flux of total phosphorus (TP) loading from the JRTP’s effluent discharge in the estuarine cove of Warwick River, and […]
