Increasing Use Of Natural And Nature-Based Features To Build Resilience To Storm-Driven Flooding, Final Report, Center For Coastal Resources Management, Virginia Institute Of Marine Science, Pamela Mason, Jessica Hendricks, Julie Herman, Karen Duhring, Carl Hershner

Reports

In coastal Virginia today, local governments are dealing with recurrent flooding driven by coastal storms, exacerbated by rising sea level and increased frequency of intense rain events. At the same time, they are confronted with increasing demands on limited resources to address issues coastal flooding in concert with water quality, wetlands management, shoreline erosion, habitat, and community needs such as infrastructure, flood insurance and open space. One solution is to maximize the protection of existing and implement new natural and nature-based features (NNBFs) to capitalize on the provision of multiple benefits to address many of these coastal issues.

New Guidance To Build Resiliency And Mitigate For Sea Level Rise As Elements Of The Chesapeake Bay Preservation Act, Pamela Mason, Julie Herman, Christine Tombleson, Jessica Hendricks, Karen Duhring

Reports

The Center for Coastal Resources Management (CCRM), Virginia Institute of Marine Science (VIMS), worked in collaboration with the Virginia Department of Environmental Quality (DEQ) and the Virginia Coastal Policy Center (VCPC) to develop guidance to inform the implementation of Chesapeake Bay Preservation Act (CBPA) regulations promulgated in 2021. The 2021 regulations added provisions to require local governments to consider climate changes, specifically flooding, sea level rise and storms, and the preservation of mature trees in the administration of the CBPA program. Specifically, CCRM developed analytical data using criteria specified in the CBPA regulations, of the National Oceanic and Atmospheric Administration …

Water Quality In Accomack County Freshwater Streams 2020, Richard A. Snyder, Paige G. Ross

Reports

Expansion of poultry house operations and use of litter as a soil amendment in Accomack County Virginia has raised concerns for water quality impacts on both seaside and bayside of the Eastern Shore of Virginia (ESVA). This ongoing investigation is examining freshwater stream water quality in Accomack Virginia to identify water quality impairments from poultry operation storm water runoff. Previous sampling data from 2019 has been integrated into this report. Sampling in 2020 followed an extended drought period (base flow) and two inch rainfall events (storm flow) in streams at road crossings in Accomack County Bayside and Seaside drainages. Dissolved …

Surface Water Nitrogen Attenuation From The Accomack County, Va Southern Landfill Groundwater Discharge - Final Report, Richard A. Snyder, Paige G. Ross

Reports

Previous sampling of the stream crossing Bobtown Road (Rt 178) near the intersection of Hollies Church Road (Rt. 620), had indicated high levels of nitrogen in the stream flow (Snyder and Ross, 2019a). The proximity of the retired Accomack County Landfill upstream of the site triggered a higher resolution sampling of the stream in an attempt to isolate a source of the nitrogen loading (Snyder and Ross, 2019b). Accomack County has requested repeated sampling of this stream segment to monitor nutrient attenuation trends from the site, and stations were established for that purpose. This Final Report provides a summary of …

2020 Chesapeake Bay Dead Zone Report, Virginia Institute Of Marine Science, Anchor Qea

Reports

The “Dead Zone” of the Chesapeake Bay refers to a volume of bottom water that is characterized by dissolved oxygen concentrations less than 2 mg/L, which is too low for aquatic organisms such as fish and blue crabs to thrive.The Chesapeake Bay experiences such “hypoxic”conditions every year, with the severity varying from year to year, depending on nutrient and freshwater inputs, wind, and temperature. Multiple metrics are used to relate the severity of hypoxia between different years:

• Hypoxic Duration (days): The number of days in a given year between the first and last day of hypoxic conditions exceeding 2 km3in …

Virginia Stormwater Act, Tiered Approach For Rural Tidewater Localities: Generation Of Watershed Impervious Maps, Christine Tombleson

Reports

An amendment to Virginia's Stormwater Management Act was adopted to implement a tiered approach to stormwater management for rural Tidewater localities. To participate a locality is required to have a map showing the boundaries of the locality, with each watershed located partially or wholly within the locality, and the percentage of impervious cover (cover that impedes the natural infiltration of water into the soil) within each watershed. Center staff created maps indicating the initial percent of existing impervious cover present in each watershed for the Middle Peninsula Planning District (MPPDC) localities; Gloucester, Essex, King and Queen, King William, Mathews, Middlesex …

Water Quality In An Unnamed Branch Of Pungoteague Creek, Bobtown Road And Hollies Church Road, Va., Richard A. Snyder, Paige G. Ross

Reports

Previous sampling of the stream crossing Bobtown Road (Rt 178) near the intersection of Hollies Church Road (Rt. 620), had indicated high levels of nitrogen in the stream flow (Snyder and Ross, 2019). During a dry period, total nitrogen was determined as 21.932 mg/L, at the end of a rain event 9.56 mg/L was recovered, and during an extended wet period without major rainfall, a value of 18.26 mg/L was found. The lower value associated with the rain event suggested dilution of a ground water source. The proximity of the retired Accomack County Landfill upstream of the site triggered a …

Water Quality In Southern Accomack County Watersheds, Richard A. Snyder, Paige G. Ross

Reports

Expansion of poultry grow out houses in Accomack County, VA has raised concerns for water quality impacts both seaside and bayside where harvesting marine resources and aquaculture operations may be affected. The dust and litter from the poultry houses are potential sources of nitrogen, phosphorous, and fecal contamination to watersheds and receiving waters. Siting regulations, storm water controls, and management of litter storage and handling are designed to limit these impacts, yet no analysis has been implemented to verify the efficacy of these protective measures. This investigation sampled watersheds after a 2 week dry period prior to a storm event …

Anthropocene Sea Level Change: A History Of Recent Trends Observed In The U.S. East, Gulf, And West Coast Regions, John D. Boon, Molly Mitchell, Jon Derek Loftis, David L. Malmquist

Reports

Relative sea level (RSL) observations since 1969 at U.S. tide stations exhibit trends in RSL rise rate and acceleration that vary in response to both global and regional processes. Trend histories display a high degree of similarity between locations in coastal regions that are experiencing similar processes. With the exception of the U.S. Northeast Coast and Alaska,every other coastal location in the continental U.S. has experienced an upturn in RSL rise rate since 2013-2014 despite wide differences in the magnitude and trending direction of RSL acceleration. High RSL acceleration along the U.S. Northeast Coast has trended downward since 2011 while …

Bacteria Tmdl Development For Lower Chickahominy River Watershed Located In Charles City, James City, And New Kent Counties, Va, Virginia Institute Of Marine Science

Reports

Section 303(d) of the Clean Water Act (CWA) and the United States Environmental Protection Agency’s (USEPA’s) Water Quality Planning and Management Regulations (40 CFR Part 130) require states to develop total maximum daily loads (TMDLs) for waterbodies that are exceeding water quality standards (WQSs). TMDLs represent the total pollutant loading that a waterbody can receive without violating WQSs. The TMDL process establishes the allowable loadings of pollutants for a waterbody based on the relationship between pollution sources and in-stream water quality conditions. By following the TMDL process, states can establish controls based on water quality conditions to reduce pollution from …
