Municipal Separate Storm Sewer System (MS4) Permittees in Virginia, including the Pentagon, are required to comply with state-mandated pollutant load reductions as outlined in their Virginia Pollutant Discharge Elimination System (VPDES) MS4 permits issued by the Virginia DEQ. Washington Headquarters Services (WHS) is the operator of the Pentagon’s MS4 Program and is responsible for compliance […]
Any addition of impervious area within a watershed, big or small, usually results in an increase in peak flow and runoff volume. This affects both water quality (due to increased pollutant load), and water quantity (issues with existing system downstream conveyance capacity, flooding, siltation and erosion). In meeting the regulatory requirements, identification of stormwater management […]
In November 2021, the City of Virginia Beach received the support of residents who voted to authorize a $567.5M bond referendum to fund the design and construction of Phase 1 Flood Protection projects located throughout the City. Since that time, staff has been developing and implementing the Program to facilitate meeting the 10-year deadline for […]
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 […]
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 […]
The City of Virginia Beach has completed the Upper West Neck Creek Drainage Basin Stormwater Master Plan (UWNC DB SWMP) which encompasses approximately 20 square miles and includes over 100 simulated flood areas (SFAs). This is the first large drainage basin completed since the Linkhorn Bay Drainage Basin Stormwater Master Plan case study (approximately 3 […]
Traditional engineered bank stabilization techniques such as riprap armoring and gabion baskets are commonly used as stream stabilization solutions in places where spot fixes are preferred over a more comprehensive stream restoration design. This is especially true is areas where existing infrastructure is compromised or failing, where stream banks are encroaching on private property, and […]
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). […]
Municipalities in Virginia are finding themselves with more and more stormwater management facilities every day. However, many of the first stormwater management facilities were designed and constructed decades ago. All of these facilities have aged, but many have not aged well. Many of these facilities have not had anybody on-site since their original construction and […]
Unmanned Aerial Systems (UAS), commonly referred to as drones, have become a popular tool used by engineering, environmental, and construction companies for site monitoring. UAS provide real-time data before, during, and after construction, helping projects to succeed on-time and as efficiently as possible. Wetlands Studies and Solutions has had success with the use of UAS […]
The Virginia Lakes and Watershed Association is a volunteer organization and its mission is to provide education on water resources in Virginia.
