Unlocking Water Quality Success: Introducing the PA MS4 Collaboration Toolkit

  Achieving water quality goals in Pennsylvania's waters is now more streamlined with the launch of the PA MS4 Collaboration Toolkit, a resource created by the Center for Watershed Protection (CWP) to empower Pennsylvania municipalities to work together and tackle water quality challenges more efficiently and cost-effectively. As federal and state agencies intensify efforts to improve water quality, local municipalities are under pressure to meet increasingly stringent requirements. Watersheds do not align with municipal boundaries, which make collaboration integral. The PA MS4 Collaboration Toolkit provides a clear, step-by-step roadmap for municipalities eager to team up and address the National Pollutant [...]

Lake and Watershed Assessment to Support Management Planning in the Lake Linganore Community, Maryland

  Lake Linganore is a growing community of approximately 17,000 residents located in rural Frederick County, Maryland. The community and its four private lakes—Lake Linganore, Lake Merle, Lake Anita Louise, and Lake Marian—are managed by the Lake Linganore Association (LLA). While the lakes offer aesthetic enjoyment and many recreational opportunities to residents, they suffer from several problems that can limit community enjoyment and heighten risks to residents. To address these concerns, the LLA hired the Center for Watershed Protection and partners Hood College Center for Coastal and Watershed Studies and Aquatic Environmental Consultants to develop a Lakes & Watersheds Appraisal [...]

LIDAR-Derived DEM Differencing As An Approach To Identify Potential Stream Stabilization Projects In Suburban Philadelphia

Stream restoration has become an increasingly common strategy utilized by watershed restoration agencies to obtain nutrient and sediment reductions to comply with Municipal Separate Storm Sewer System (MS4) and Total Maximum Daily Load requirements. As such, practitioners are seeking more efficient methods to evaluate stream reaches where sediment delivery could be reduced, and to report credits for sediment and nutrient reductions. Traditional methods to estimate credit for streambank stabilization include monitoring and modeling approaches, such as the Bank and Nonpoint Source Consequences of Sediment (Rosgen, 2001) method used for MS4 crediting in the Chesapeake Bay watershed and in other parts [...]

Providing Stormwater Leadership in the Delaware River Watershed

  The Center for Watershed Protection (CWP) recently wrapped up a seven-year stretch as a Technical Field Liaison for the National Fish and Wildlife Foundation (NFWF)’s Delaware River Restoration Fund.  The Fund was launched in late 2013 with major funding from the William Penn Foundation to help community-based nonprofits to clean up and restore polluted waters and improve habitat for target species across the four-state Delaware River basin.  As one of several Technical Field Liaisons, CWP assisted potential grantees in developing proposals that align with funder priorities; assisted NFWF with proposal review; worked with grantees to ensure successful completion of [...]

PCB Source Assessment for Baltimore County

  Polychlorinated biphenyls (PCBs) are a class of human-made compounds widely used from 1929 through 1979 in manufacturing and industrial applications because of their exceptional fire-retardant and insulating properties. Rising concerns about the toxicity, human health effects, and persistent nature of PCBs in the environment led to a federal ban on the sale and production of PCBs in 1979. Even though PCBs have not been manufactured for many years, their unregulated, historic uses have led to “legacy” PCB contamination. In Baltimore County, Maryland, PCB total maximum daily loads (TMDLs) have been established by the state for four waterbodies; however, few [...]

Building Capacity for Low Impact Development in Washington, DC

  Stormwater runoff is problematic throughout the District of Columbia. Since most land within the District has already been developed, improvements to stormwater management rely, for the most part, on voluntary installation of “low impact development” or LID practices as retrofits. These practices aim to retain runoff and reduce the amount of pollution entering District waterways. In 2018, CWP received a grant from the District of Columbia Department of Energy and Environment to build capacity among the city’s nonprofit business districts for the installation and maitnenanceof  LID projects.  These entities provide education and outreach to businesses and residents in their [...]

Targeting Outfall Screening Based on Pollution Risk in Baltimore County

  CWP, through an on-call engineering agreement for watershed planning services, assisted the Baltimore County Department of Environmental Protection and Sustainability with developing an outfall screening plan for the County’s more than 12,000 stormwater outfalls. Baltimore County’s stormwater permit requires that the County develop a plan to prioritize outfall field screening efforts in areas with the greatest potential for illicit discharges—defined as discharges that are not composed entirely of stormwater—which are prohibited by the County’s regulations. CWP conducted a series of geospatial analyses that began with an Outfall Inventory to ensure the data associated with stormwater outfalls in the County’s [...]

2023 National Watershed & Stormwater Conference Highlights

  The CWP 2023 National Watershed & Stormwater Conference, Value of Water – Stormwater Harvesting & Reuse, Nutrient Trading and Funding, was held April 24-27, 2023, at the Westin in the Gaslamp Quarter in San Diego, CA. This annual conference provides a forum for sharing fresh ideas on watershed and stormwater management principles and practices. For four days, over 200 watershed professionals from federal, state, and local government agencies, consulting firms, universities, and non-profits from across the nation (and some international) gathered for technical presentations, case studies, panel discussions, and workshops. And as always, with CWP events, the conference was [...]

Green Infrastructure Assessments for Coastal Resilience

  The  Southeast Michigan Council of Governments  (SEMCOG) and  Center for Watershed Protection  (CWP) were awarded a Michigan Coastal Management Grant to assess locations to build coastal resilience in Southeast Michigan. Through this grant, the project team coordinated with communities to identify high-priority, publicly-owned properties and assess feasibility for green infrastructure. Southeast Michigan has an extensive coast, spanning 400 miles of Great Lakes shoreline from Lake Huron to Lake Erie connected by the St. Clair River, Lake St. Clair and the Detroit River. It is shared by four coastal counties (St Clair, Macomb, Wayne, and Monroe) and 37 coastal communities. [...]
