As the tide rises, inundates the landscape, and then recedes, it can transport organic and Tidal flooding inorganic matter between terrestrial systems and adjacent aquatic environments. However, the chemical and Nitrogen loading biological effects of tidal flooding on urban estuarine systems remain poorly constrained.

  • A Clear Expression of Purpose
    The Park System of Norfolk, Virginia An Analysis of its Strengths and Weaknesses By The Trust for Public Land Center for City Park Excellence Washington, D.C. February 2005 Introduction and Executive Summary A venerable city with colonial-era roots, Norfolk, Virginia, has an increasingly bright future as the center of its large metropolitan area at the mouth of the Chesapeake Bay. In 2004, with their city in the midst of an impressive civic renaissance, a group of Norfolk citizen leaders became interested in knowing the state of Norfolk’s park and recreation system and how it compares with those of other similar cities. They turned to the Trust for Public Land’s Center for City Park Excellence, which is known for its studies of urban park systems, and contracted for an overview and analysis of Norfolk. With the assistance of the Bay Oaks Park Committee, and with cooperation from city officials, TPL undertook this study of Norfolk’s park system. Data on the system’s acreage, budget, manpower, and planning process was supplemented by interviews with city leaders, park and planning staff and Norfolk’s citizens. Utilizing an extensive database of city park information Norfolk was evaluated both on its own merits and against other American cities. By dint of time and budget, TPL’s analysis is not comprehensive; it only provides an initial set of snapshot views and comparisons. Nevertheless, the findings of this study are clear enough. By almost every measure, TPL finds that while the city of Norfolk has some wonderful parks, scenic riverfronts, tree-lined boulevards and sandy beaches, it simply doesn’t have enough of them.

  • State of the Elizabeth River 2014
    State of the Elizabeth River Scorecard 2014 November 17, 2014 Scientific data compiled & analyzed by: Elizabeth River State of the River Steering Committee 2014, Convened by Virginia Department of Environmental Quality and The Elizabeth River Project Summarized and interpreted for the public by: Summary: From Almost Dead to an Average Score of C And Most Notorious Branch is Now the Most Improved Parents might not think a C is too hot, if your kid brings it home from school. But when one of the three most toxic rivers on the Chesapeake Bay brings home a C, that’s reason to celebrate. The Elizabeth River was commonly presumed dead when The Elizabeth River Project entered the picture in 1993. Fast forward to 2014. Area scientists have scored each of the branches of the Elizabeth for an average overall health of C for this urban river. Better news yet: The notoriously polluted Southern Branch of the Elizabeth River shows the most improving trends. This is the long stretch of the river that has been industrialized since before the Revolution; the branch too often in the past was described as devoid of life. For this report, area scientists found improving trends for bacteria, nitrogen, bottom health, and contaminants on the bottom of the Southern Branch. A committee of local, state and regional scientists prepared this State of the River report for The Elizabeth River Project and VA Department of Environmental Quality to determine changes since the last comprehensive scorecard for the Elizabeth River, issued by the same partners in 2008, and to identify trends over the last 10 years.

Received: 24 September 2013; in revised form: 28 October 2013 / Accepted: 28 November 2013 / Published: 8 January 2014 Abstract: Algal blooms are dynamic phenomena, often attributed to environmental parameters that vary on short timescales (e.g., hours to days). Phytoplankton monitoring programs are largely designed to examine long-term trends and interannual variability. In order to better understand and evaluate the relationships between water quality variables and the genesis of algal blooms, daily samples were collected over a 34 day period in the eutrophic Lafayette River, a tidal tributary within Chesapeake Bay’s estuarine complex, during spring 2006. During this period two distinct algal blooms occurred; the first was a cryptomonad bloom and this was followed by a bloom of the mixotrophic dinoflagellate, Gymnodinium instriatum.

The native oyster, another important filter for the control of algae, has been decimated by disease, overharvesting and poor water quality. One top source of excess nutrients is often ignored - air pollution. As much as 34 percent of the nutrient problem in the Chesapeake Bay is attributed to air pollution. Pollutants in the air eventually fall either to the ground, where it can wash into the water, or falls directly in the water. Wetland grasses filter pollution and create a rich habitat for fish, shellfish and wading birds. While much restoration work remains, the Lafayette River still features about 375 acres of tidal wetlands, half of all wetlands in Norfolk. Photo courtesy of Kenn Jolemore.
