Summary

The National Park Service Geologic Resources Division (NPS GRD) is working with the University of Colorado Boulder to develop sea level change and storm surge data that parks can use for planning purposes over multiple time horizons. 

Background

Coastal parks frequently ask the division how individual parks will be impacted by sea level change. Parks need this information to prepare foundation documents and to calculate storm surge projections. Many park managers would prefer data for shorter time horizons (e.g., 2030, 2050) than is widely available in the academic literature. Although several National Oceanic and Atmospheric Administration (NOAA) models can simulate storm surge, most parks do not have tide gauges or other historical records of sea level to input into the models. The NPS GRD is using the latest Intergovernmental Panel on Climate Change (IPCC) data to “fill in the gaps” between tide gauges to give parks the latest sea level change data tailored specifically for their park. 

Implementation

The NPS GRD is collecting the most recent data on sea level change and storms, primarily from the academic literature, in addition to projection data generated in-house and provided by other researchers. These data are used to assist with state of the parks reports, general management plans, and foundation documents at parks including, most recently, Santa Monica Mountains National Recreation Area, Cumberland Island National Seashore, Cape Lookout National Seashore, Timucuan Ecological and Historic Preserve, and San Juan National Historic Site. 

The division uses IPCC and US Army Corps of Engineers data to generate new data that can be projected on multiple time horizons to help the parks. A three-year project began in fiscal year 2013 to analyze rates of sea level change coupled with potential storm surge in 118 of the coastal parks in order to project, for each park, the combined elevations of storm surge and sea level by 2030, 2050, and 2100. 
 
NOAA Sea, Lake and Overland Surges from Hurricanes (SLOSH) model data have already been incorporated into 34 foundation documents, 9 state of the parks reports, and various assistance requests (e.g., Gulf Islands National Seashore, Acadia National Park, Assateague Island National Seashore, Boston Harbor Islands National Recreation Area, Colonial National Historical Park, Gateway National Recreation Area, Fire Island National Seashore, and Statue of Liberty National Monument). Individual sea level change and storm surge projections for each park will be released in a full report during the NPS Centennial Celebration in fiscal year 2016. Interim products that have been supplied to the parks as part of foundation documents or state of the parks reports can be found at https://irma.nps.gov. Sea level change and storm surge data will be featured in the park atlas and as a separate interactive website. In the meantime, storm surge maps are already available at https://www.flickr.com/photos/125040673@N03/sets/
 
Three parks will also be selected for funding to install waysides highlighting the issue of sea level change. Gulf Islands National Seashore has been selected as the first park to receive funding, which they have used to install two waysides explaining the challenges of rising sea levels along the Gulf of Mexico coast. 

Outcomes and Conclusions

This project is ongoing and will take three years to complete.

This case study is part of the 2015 National Park Service report, Coastal Adaptation Strategies: Case Studies. These case studies initially were developed by park managers as part of a NPS-led coastal adaptation training in May 2012. The case studies follow the format created for EcoAdapt’s Climate Adaptation Knowledge Exchange (CAKE) database, including a list of adaptation strategies. All case studies were updated and modified in September 2013 and March 2015 in response to a growing number of requests from coastal parks and other coastal management agencies looking for examples of climate change adaptation strategies for natural and cultural resources and assets along their ocean, lacustrine, and riverine coasts.

Case Study
Summary: 

Assateague Island National Seashore is developing a general management plan that addresses projected climate change impacts on resources and infrastructure. The plan must include a range of management tools for improving resource resiliency and repairing facilities that will be impacted by climate change and storms.

Assateague Island National Seashore is responsible for maintaining and managing access to a recreational beach that is impacted by storms multiple times each year. Maintaining the recreational beach in its present location is unsustainable in the face of continued storms, shoreline erosion, and sea level rise.

Summary: 

Climate change impacts, including coastal erosion, reduction in sea ice, and thawing of permafrost, are impacting Bering Land Bridge National Preserve (BELA) and Cape Krusenstern National Monument (CAKR) along the northwestern Alaska coast.

Adaptation Phase: 
Assessment
Summary: 

Climate change has increased the vulnerability of cultural resources in coastal locations at Bering Land Bridge National Preserve and Cape Krusenstern National Monument along the northwestern Alaska coast. The Alaska Regional Office is developing and testing a GIS model that is intended to predict locations and vulnerability of these cultural resources.

Case Study
Summary: 

Gateway National Recreation Area partnered with other state and federal agencies to restore wetlands in Jamaica Bay, a eutrophic urban estuary, through sediment addition and plantings. While the project was not driven by climate change concerns, addressing marsh elevation loss is consistent with methods to address sea level rise.

Summary: 

Golden Gate National Recreation Area is collaborating with local, state, and federal agencies to develop a long-term management strategy for Ocean Beach, where bluff erosion threatens natural and recreational resources, wastewater infrastructure, and a roadway (the Great Highway). Sea level rise and increased storminess are expected to increase the frequency of erosional events.

Case Study
Summary: 

In Florida, the Fort Pickens Road within Gulf Islands National Seashore is regularly destroyed by storms, and repairs are expensive and time consuming. The park continues to reevaluate the local conditions and implement cost-effective, sustainable modes of visitor access to Fort Pickens beaches and the historic fort. 

Summary: 

The large-scale project known as the Mississippi Coastal Improvements Program (MsCIP) is intended to restore multiple barrier islands and protect cultural resources within Gulf Islands National Seashore by recreating sediment transport processes and replacing a portion of sediment lost to dredging and storm impacts.
