Chesapeake Healthy Watersheds Assessment

In 2017, the EPA’s Healthy Watersheds Program published the results of their Preliminary Healthy Watersheds Assessments (PHWA), a project that brought together nationally consistent data to assess watershed health and vulnerability. The HWGIT agreed that a similar regional assessment utilizing jurisdiction specific data could address major gaps identified in the Healthy Watershed’s Management Strategy. Building on the PHWA framework, HWGIT contracted Tetra Tech to complete a Chesapeake Healthy Watersheds Assessment (CHWA) to help partners identify “signals of change” in vulnerable or resilient healthy waters and watersheds. The final report was published in 2019 and is available below. In order to visualize the results, Innovate!, Inc. developed an application to facilitate exploration of the data. The readily available online, geospatial tool supports and informs management related to watershed health and vulnerability at the catchment scale. See the flyer below to read more, and access the tool directly here.

Maryland Healthy Watershed Assessment

In 2020, the Maryland Healthy Watershed Assessment (MDHWA) was funded through a Goal Implementation Team Funding project. Development of the MDHWA establishes a framework of watershed health and vulnerability metrics for assessing Maryland waters and watersheds. Development of this statewide assessment built upon the previously completed Chesapeake Bay Healthy Watersheds Assessment (CHWA) (Roth et al. 2020). The assessment is intended to inform watershed management decision-making to sustain the health of state-identified healthy watersheds, which have been defined in Maryland as the watersheds associated with its designated high-quality, Tier II waters. The MDHWA will increase State capacity to better understand the broad spectrum of health and vulnerability issues affecting Maryland’s streams and healthy watersheds. The MDHWA will also serve as a model that can be replicated in other jurisdictions and updated in future assessments.

Map of State-Identified Currently Healthy Waters and Watersheds (2017)

The most current (2017) map of state-identified healthy waters and watersheds and the 2015 map. The Healthy Watersheds Outcome in the Chesapeake Bay Watershed Agreement states that one hundred percent of these waters and watersheds will remain healthy.

Healthy Watersheds Forest Retention Studies (Phases I, II and NEWLY released Phase III):

The Healthy Watersheds/Forest project is a Virginia-led, multi-year, landscape-scale effort begun in 2015 that is now in nearing completion in phase III. The goal of this project was to research and pilot alternative methods for forest and agricultural land conservation through three separate phases. Phase 1 modeled and tested alternative land use growth scenarios in a portion of the Rappahannock River Basin as a proxy for the Chesapeake Bay watershed by employing the methodology used by EPA TMDL modelers and using real land use data from the localities in the test area to determine the potential value of a BMP in the TMDL model for retaining forestland. In Phase II, Pennsylvania partnered with Virginia to determine what from the perspective of local leaders were the economic and policy incentives needed to prioritize forestland retention as a land use planning option. Phase III developed and piloted the community policy and financial infrastructure necessary to facilitate high quality forest and agricultural land conservation/retention on a sustainable, landscape scale basis. Phase III was divided into two tasks. Task 1 focused on collaborating with the municipal authorities responsible for the plans, policies and ordinances in the two pilot counties. Task 2 focused on developing a transferable financial model in the pilot counties to incentivize private capital markets to invest in the retention of forest and agricultural lands to offset future forecasted growth and development based on the 6.0 Chesapeake Bay Total Maximum Daily Load (TMDL) model. The ultimate goal has been to create a favorable regulatory environment and incentives for private landowner participation in land conservation while also contributing to the funding requirements of counties to help them meet basic services for their citizenry through a model that can attract private sector financial interest at a scale required to achieve the Phase III goal. This Phase III report covers the research, findings and activities from the start of phase III in April 2018 through September 30, 2019, the end-date for the Chesapeake Bay Trust-funded grant period. The focus of the project team from this point forward to the end the project next Spring (with additional funding from the US Endowment for Forestry and Communities) will be on (1) designing and testing in collaboration with Orange County Virginia, the Economic Development Authority infrastructure required to aggregate landowner interests effectively, and (2) further engaging with the private financial sector to solicit its interest in participating in the Virginia approach, while refining the financial options to best meet landowner, locality and investor needs.
