Due to wide ranging, and often differing problems present throughout the watershed, the issues focused on in each state (DE, MD, NY, PA, VA, and WV) and the District of Columbia may vary. To identify the issues in the Chesapeake Bay watershed, the CBCP team will perform a three tier multi-scalar analysis using readily available geospatial data.
The first and largest scale analysis (Tier 1) will be completed across the entire extent of the Chesapeake Bay watershed. The analysis will use a number of watershed health indicators, e.g. black duck, wetlands, SAV, and future/projected land use and sea level change, to prioritize high value habitats and restoration needs for the entire watershed and identify broad USACE project types, programs, and authorities that can be utilized to address those needs.
The second scale analysis (Tier 2) will be completed corresponding to the scale of each of the Bay states and the District of Columbia. The purpose of this second, state-scale analysis is to present the results of the CBCP Tier 1 analysis at the state level for each of the basin states, which have regulatory requirements and commitments to continue to strive toward achieving Bay restoration goals. Presumably, this information could be used to align state restoration activities and ensure advances are made towards the restoration of the Chesapeake Bay watershed.
The third scale analysis (Tier 3) identifies a priority subwatershed per jurisdiction, pinpointing potential actions that could be taken at the local scale. It is envisioned that the subwatershed scale analyses would provide the jurisdictions with additional assistance in
further developing a smaller scale watershed action plan. Further coordination with the jurisdictions on the extent of the analyses will be completed and constrained by the schedule to finalize the CBCP by July 2018.
The intent of the multi-scalar approach in the CBCP is to be able to present at the Bay-wide scale what actions are needed to focus Bay restoration efforts that crosses state lines. After completion of each of the analyses, public and private organizations can then align with state and local agencies to discuss which actions will be taken to contribute to restoration efforts at a state and local level.
