Shoreline Management Handbook, Pamela Mason, Angela King, Clay Bernick Apr 2020

Shoreline Management Handbook, Pamela Mason, Angela King, Clay Bernick

Reports

Shoreline habitats and processes are impacted by the decisions we make about managing coastal development and shorelines. Shoreline Management is making choices to address the desire to protect upland property from erosion or develop property balanced with the benefits and uses of natural and nature-based shoreline features and shoreline habitat restoration. This requires a weighing of the private benefits and cots of management actions and the benefits and costs to public held common resources, also known as the public trust. The natural features along our shorelines -tidal wetlands, beaches and dunes, and riparian buffers, are economically and ecologically valuable. They ...

The Commonwealth of Virginia owns numerous tidal, waterfront properties along Chesapeake Bay and its tributaries including state parks, natural area preserves, and wildlife management areas. Many of these parks have eroding shorelines and are at risk from coastal hazards such as tidal flooding, waves, and sea level rise. These environmental threats impact the safety of park visitors and the mission of the parks.

In an effort to address these issues for the parks as well as provide education to the public on living shoreline management strategies, eleven state parks with tidal shoreline along the Chesapeake Bay and its tributaries were ...


Living Shoreline Sea-Level Resiliency: Performance And Adaptive Management Of Existing Sites, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox Nov 2018

Living Shoreline Sea-Level Resiliency: Performance And Adaptive Management Of Existing Sites, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox

Reports

The goal of this project is to monitor effectiveness of nature-based resiliency projects such as those that use living shoreline management strategies. Living shoreline strategies can effectively control shoreline erosion while providing water quality benefits and maintaining natural habitat and coastal processes. These ecosystem-based management systems have been the preferred alternative for stabilizing tidal shorelines in the Commonwealth of Virginia since 2011. However, a recent analysis has shown that between 2011 and 2016 only 24% of the permits granted for shore protection were considered living shorelines (ASMFC, 2016). These types of systems may be relatively new to many landowners and ...


Oyster Bag Sill Construction And Monitoring At Two Sites In Chesapeake Bay, Donna A. Milligan, C. Scott Hardaway Jr., Christine A. Wilcox, Walter I. Priest Oct 2018

Oyster Bag Sill Construction And Monitoring At Two Sites In Chesapeake Bay, Donna A. Milligan, C. Scott Hardaway Jr., Christine A. Wilcox, Walter I. Priest

Reports

The use of oyster shell bags as a means of shore protection along fetchlimited shorelines in Chesapeake Bay is growing. This method is an innovative use of a byproduct of the seafood industry and can provide habitat creation, water quality improvement, and shore protection. The landowner can install the bags themselves, and with the new living shoreline general permit in Virginia, these projects are easier than ever to afford and install. However, oyster shells are a limited resource that are needed for largescale oyster reef restoration with the Chesapeake Bay watershed, so determining the effectiveness of this shore protection strategy ...

A Brief Guide To Striped Bass Ecology & Management In Chesapeake Bay, Mary C. Fabrizio, Troy D. Tuckey, Susanna Musick Nov 2017

A Brief Guide To Striped Bass Ecology & Management In Chesapeake Bay, Mary C. Fabrizio, Troy D. Tuckey, Susanna Musick

Reports

Chesapeake Bay striped bass support important recreational fisheries along the US Atlantic coast; in the late 1970s, the population of striped bass collapsed as a result of overfishing and poor water quality in rivers used for spawning and rear-ing of young. Informed by stock assessments, strict management regulations were enacted in the mid-1980s and early 1990s; these highly effective regulations resulted in the recovery of the population in 1995. A key to the successful recov-ery of the Atlantic coast striped bass was the wide range of ages of spawning females and the associated differences in spawning behavior among ages. Age ...

Kepone In The James River Estuary: Past, Current And Future Trends, Michael A. Unger, George G. Vadas

Reports

In late 1975, a manufacturing facility in Hopewell, VA had not only exposed workers to the chlorinated pesticide, Kepone, but had also severely contaminated the James River estuary. To assess the potential risk to the public, Virginia initiated a finfish-monitoring program in late 1975. Over the next 40 years over 13,000 samples were collected from the James River and Chesapeake Bay and analyzed for Kepone. Kepone production was eventually banned worldwide. The average Kepone concentrations found in most species began falling when the production of Kepone ended, but the averages remained over the action limit of 0.3 mgkg ...
