Description:
Abstract:
Climate change is likely to accelerate the historical rise in sea level, leading to a wide range of impacts on development, wetland resources, and recreation in the U.S. coastal zone. Relative sea level (i.e., the net impact of sea and land level changes) is already rising in most parts of the U.S. The UN Intergovernmental Panel on Climate Change concluded in 1996 that increases in global temperatures over the next century could accelerate the historical rate of sea level rise to an average of about 5 mm/yr (or 50 cm/century). Low-lying and higher elevation lands along the coast may also be threatened by other coastal hazards such as erosion and storms.

The impacts of this increase in sea level, will vary from place-to-place and depend on a range of factors, including the human response. To initiate a national assessment of sea level rise impacts, the U.S. Environmental Protection Agency (EPA) is working with state, county, and local officials to identify the lands likely to receive shoreline protection. Those judgments incorporate state policies and regulations, local concerns, land-use data, and general planning judgment. The resulting data distinguishes areas likely to receive shoreline protection (e.g., beach nourishment and armoring with seawalls or dikes) from the areas where shores will probably retreat naturally, either because the cost of holding back the sea is greater than the value of the land, or because there is a current policy of allowing the shore to retreat. This data should be used in conjunction with information contained in the corresponding planning report ("Anticipated Responses to Sea Level Rise in Delaware").

Purpose:
This data and the accompanying report are part of a national effort by EPA to encourage the long-term thinking required to deal with the impacts of sea level rise issues. The nature of rising sea level prevents the issue from being a top priority; but it does give us time to reflect upon how to address the impacts. Maps that illustrate the areas that might ultimately be submerged convey a sense of what is at stake, but they also leave people with the impression that submergence is beyond their control. Maps that illustrate alternative visions of the future may promote a more constructive dialogue.

Through the development of data on the likelihood of shoreline protection, this research seeks to (1) improve future assessments of the impacts of climate change through incorporation of a richer understanding of local land use policies and trends; (2) improve the understanding among federal, state, and local levels of government on the effect of current coastal policies on coastal development and conservation; and (3) identify opportunities for policy refinement to facilitate a more efficient response to rising seas that limits the impact on coastal property, wetlands, and recreational resources.

Supplemental_Information:
When displaying the data, the study authors recommend using the corresponding layer file to ensure that the classifications display in the same way as all print maps created for this study. For instance, brown is used to designate lands where shore protection is almost certain (red designates shore protection likely, blue designates shore protection unlikely, and light green designates no shore protection). Users should store the layer file and associated GIS data in the same folder and then can add the layer file to an ArcGIS project.

Users should display wetlands and the outside-of-study-area layers on top of this data set. This study only focused on dry land that is either below the 20-foot contour or within 1000 feet of the shore. The response data for lands located outside of the study area or beneath non-tidal wetlands is typically misleading and has not been reviewed. Wetlands data and the outside-of-study-area data layers are available separately.

Step 1: Identify "decisions rules" for mapping anticipated likelihood of shoreline protection

Industrial Economics, Incorporated (IEc) initiated the study by researching state and county laws and plans to determine the policies that affect coastal management decisions. Next, we conducted interviews with state regulators and county planners to investigate existing and anticipated coastal policies and land uses. Their knowledge about local priorities and wishes allow us to glean broad policy directions of shoreline protection efforts based upon land use. County and state planning staff were asked to consider the anticipated planning responses given rising seas of 1-3 feet in the next 100 years and as much as 10 feet over the next few hundred years. We also discussed public access to the water, economic conditions, areas of cultural or historical importance, and flood-prone areas.

State and local officials had not previously assessed the areas that might ultimately be protected, aside from a few areas with well-known erosion problems. Nevertheless, the primary question for this study involves many of the same issues that planners routinely consider, most importantly: which areas will become densely developed, and which areas will be placed off-limits to development. Because the results of such considerations are increasingly published as a GIS data layer, the study authors assumed at the outset that wherever possible, we would rely on available land use data, especially data on land use plans, existing land use and land cover, and boundaries of conservation areas.

IEc asked the planners to identify general categories of lands that would be protected or lost under different scenarios. If possible, those general categories correspond to a designation in a GIS dataset, which enabled us to create a generalized sea level response map by applying a "decision rule" to the data. During the initial meetings, we also requested copies of any GIS-based or hardcopy maps that help illustrate anticipated responses in the county. Typically, however, site-specific discussions were noted only on a hardcopy map and not available via GIS data.

The study authors urge users of this data to refer to the planning report for additional information on the methodology and data.

Step 2: Obtain additional GIS data on land use, conservation lands, and other features

Based on the input of state and local planners, IEc next gathered the additional GIS data needed to reflect their suggested decision guidelines. For a list of data acquired and the source of the data, please refer to Table 2 and the data source Appendix of the "Assessment of Sea Level Rise Response Scenario in Delaware" planning report. As shown, we obtained relevant GIS data layers from a variety of sources including the state's Department of Natural Resources and Environmental Control and the Department of Agriculture as well as the University of Delaware's Spatial Analysis Laboratory.

This analysis initially employed ArcView 3.2 for the GIS work. As a result, where necessary, IEc reprojected data to NAD1983 StatePlane Delaware Meters. In later steps of the analysis, we used ArcGIS software that automatically reprojects the data ("on the fly") to the StatePlane coordinate system. Thus, for new data added after the initial steps the data projections may have varied. During the final stage of the analysis; however, all data were projected to the same coordinate system for finalization.

Step 3: Creation of draft maps

The first step in creating the draft maps was to define the study area. We intended to include all dry lands that are either below the 20-foot (NGVD) elevation contour, or land within 1000 feet of the shore. Because the USGS maps in much of the region have contour intervals of 20 feet, this was the only way to be certain that we included all the land that might be vulnerable. We later included land within 1000 feet of tidal wetlands or open water, to account for possible erosion. Although our study area extends to the 20-foot contour, most uses of these maps will probably not extend to such a high elevation. For example, if one wanted to analyze the area protected from inundation with a one meter rise in sea level, one need only consider the land within one meter above the ebb and flow of the tides (see the elevation data available at <http://maps.risingsea.net/data.html/>).

In spite of that intention, however, we lacked an accurate definition of the 20-ft contour. Prior to implementing the stakeholder review we integrated a revised outside of study area data set that ICF Consulting created for use in the project based upon the coastal elevation data referenced above. In addition, this layer also incorporates a 1000 foot buffer from the mean high water line to ensure that we would be able to display response information for cliff areas immediately adjacent to the coast. The revised version of this outside of study area data is available at <http://maps.risingsea.net/data.html>.

IEc then used the data collected under step 2 to create separate response maps for each county. For each county, we created separate GIS projects that contained all GIS data applicable to the county (e.g., land use, conservation data, site-specific data) ordered to match the priority of the various "decision rules" developed during Step 1 (interviews with local officials). Initially, when mapping the sea level rise responses we used three sea level rise scenarios. The first scenario identifies lands for which local policies and practices allow protection. The second identifies land that planners feel is likely to be protected. The third scenario uses the second scenario as a starting point, but assumes greater efforts would be undertaken to preserve natural resources (e.g., tidal wetlands) or protect historical structures. For more information on each of these scenarios, see Table 1 in the planning report.

After the initial interviews for this study were completed, the EPA project manager realized that for some purposes, it would be more useful to display all three scenarios on a single map, rather than expect readers to hold the maps next to each other to observe differences. As a result, at this stage in the study we switched to using a single map with multiple colors that represent varying likelihoods of shoreline protection. Table 1 of the planning report provides information on the methods used to switch from the scenario-based approach to our current range of shoreline protection likelihoods.

To map the likelihood of shoreline protection in each county, IEc added the GIS data and stacked the data in the corresponding priority of the decision rules. The planning report includes tables that list the drawing order of the GIS data. For example, GIS data depicting site-specific differences are displayed above the more general decisions (e.g., existing developed land shown as certain to be protected, undeveloped lands shown as unlikely to be protected). Where necessary, a single layer may be included multiple times at different locations in the drawing order with different components displayed. For example, land use data provides information on different land categories. We might display the data at the bottom of the project to show all undeveloped land as shore protection unlikely and then add a second instance of the data further up in the drawing order to show all developed land as shore protection almost certain. For cases where planners identified site-specific decision rules during the initial planning meetings, we created separate data layers by selecting the corresponding area from the land use data and exporting the polygon(s) as a new layer. We then added the site-specific layers in the correct drawing order location and set the symbology to match the appropriate color for the protection scenario (for information on the protection responses and corresponding color used for display, see the attribute information for the Scenario field).

For information on the data used for specific counties, readers should refer to the planning report.

Step 4: Expansion of study area to include Nanticoke River Valley.

The EPA project manager also requested the expansion of the study area to include the Nanticoke River Valley in the western portion of Sussex County. IEc expanded the GIS projects to include this area using the specific polygons of the original GIS data that cover the river valley. For information on the mapping approach employed for the Nanticoke River valley, refer to the planning report.

Step 5: Integrate stakeholder review changes.

After creating the draft maps, IEc produced jpg-format images and hardcopies of each county map on 11x 17" paper. The EPA project manager then distributed copies to each of the individuals interviewed under step 1. These maps included ESRI major road data for reference purposes. The corresponding scale of the paper maps ranged from approximately 1:150,000 to 1:250,000 depending upon the size of county. During additional meetings with the planners, he solicited feedback on the maps to identify necessary changes. To the extent possible, we asked planners to identify changes by drawing a polygon around each area. He then noted the change that was needed for these areas. In some cases, planners only provided an oral description of changes needed. In those cases, he recorded the town or other geographic area described and the requested change.

In most cases, IEc implemented each change by selecting the polygon(s) that existed within the area and exporting these selected polygons as a new shapefile. We revised the likelihood of protection identified in the layer attributes and added the new layer to the county project.

When the boundaries of the site-specific change did not overlap with the boundaries of land use polygons, we used ArcGIS's edit functions. All edits were then implemented through heads-up digitizing using ArcGIS software. When possible we would first identify all the polygons in the land use data for which a portion of the area extended into the site-specific change. After exporting these polygons into a separate layer, we would then edit the new layer. Alternatively, in some cases, we used the edit function to create a new polygon in the shapefile. When using the edit function we would identify the boundaries of the area using available landmarks such as roads and manually create or split the polygons. In the few cases where roads could not serve as a landmark, we zoomed into the area involved (at a screen scale of 1:10,000 or better) and made the edit based upon the shape of nearby features such as shoreline or wetlands. The resulting data were then added to the appropriate project.

The fact that the review took place at a scale smaller than 1:100,000 could potentially reduce the resolution of our maps. We do not believe that the deterioration was significant. The types of changes that the officials sought were generally for relatively large areas corresponding to the size of parks and new communities. The primary source of error for these maps is not the precision of well-defined boundaries, but rather the uncertainty of how land use will evolve in undeveloped areas.

Step 6: Data finalization.

ICF Consulting received protection scenario data, by county, from IEc. Prior to finalizing the data, ICF created a series of "transfer confirmation maps", which the EPA manager reviewed to confirm that the maps were unchanged.

ICF then developed several geoprocessing models, using ESRI's Model Builder, to "flatten" the data into single state-wide files. The process of flattening the data involves combining or unioning each of the source data layers together to create the single file.

The models take the data layers that collectively create a state's sea level rise protection scenarios and flatten them into a single file. During the flattening process, all files are projected into an appropriate projection for the state. The models assign common attributes of shore protection, an appropriate source, whether or not it is military owned land, county name, state name, and if it is to override wetland data. Counties are flattened individually and then another model is used to combine all counties into a single state layer. Any edits that have been made to the protection scenarios are flattened and all attributes are verified.

Using this "flattened data", ICF created 1:100,000 "comparison maps" for the EPA manager to review. Those maps explicitly highlighted areas that had been erroneously masked (as wetland or high ground) during previous phases of the study, and hence not received the same level of scrutiny as most of the study area. The comparison maps included 1:24,000 TIGER road layer data.

Step 8: Review of Comparison Maps

The project manager examined the comparison maps and made three types of corrections.

First, these maps used better elevation and wetlands data (see data at <http://maps.risingsea.net/data.html>). The new data unveiled areas that had been covered by the draft elevation and wetlands masks, for two reasons. (a) the newer wetlands data often reclassified wetlands to dry land due to development and other land use changes taking place after the older (NWI) wetlands data was created (b) the original mask was the 3.5-m contour from a 1:250,000 data set, while the new mask was based upon a 20ft contour from a 1:24,000 data set. Even if the data were precise, land between the 3.5-m and 20-ft contour would be unveiled. The EPA project manager reviewed the unveiled areas (which had not been previously viewed by planning staff) to ensure that the designations fit with the decision rules noted by the planners. To identify the changes, he identified anomalies in the map such as unveiled blue areas existing in an otherwise brown area, unveiled blue areas with substantial road layers, unveiled brown areas with no roads, or unveiled red or brown areas surrounded by wetlands in an area where local officials had indicated that future development is unlikely. He also examined the unveiled lands to locate conservation lands (light green or blue). If the conservation land matched with the decision rules identified for the county, then no change was implemented. If the conservation land did not match the decision rules, he requested the map changes necessary to correct the situation.

Second, the project manager looked for lands that would not be protected due to our decision rules, but would be inherently protected by the protection of nearby lands. For example, if a land area were shown as unlikely to be protected but surrounded by land almost certain to be protected, then the protection level for the surrounded polygon would be set to match the nearby area. If an area was on high ground (and thus only at risk of erosion), then only the adjacent property closest to the shoreline had to be at the higher protection category to be changed. On lower ground, where properties could become inundated from any direction, the polygon had to be surrounded by a higher protection level to be changed.

Along relatively high ground shores, where erosion is the primary risk, protecting shorefront developed lands has the direct effect of protecting undeveloped inland farms, whether or not protection is otherwise expected for that land use category. In lower areas, lands can be submerged from the back side even if shorefront homes are protected. For those areas, he edited the protection designation only if a polygon is entirely surrounded by land that are more likely to be protected.

Finally, the project manager examined areas with substantial road networks that were designated blue. If the report assumed that such areas will not be developed, he changed those areas to red, except that if the area was immediately adjacent to a brown area, he changed it to brown.

ICF then implemented the final changes by selecting the corresponding polygons in the final response data and changing the source and scenario response fields accordingly.
