Memorandum #1: Task 1 – Establish Study Parameters

The Town of Falmouth has contracted with Woods Hole Group to complete a Climate Change Vulnerability Assessment and Adaptation Planning project. The goals of this project are to:

• Provide data on likely future flooding scenarios; • Identify potential flooding impacts to municipally-owned infrastructure; • Identify potential sea level rise impacts to natural resources; • Identify potential adaptation strategies to reduce risk; • Prioritize investments in adaptation strategies; and • Produce high-quality maps and graphics that can be used to disseminate project results to decision makers and the general public.

This memorandum provides documentation of the initial project phase to select study parameters for the Town of Falmouth Climate Change Vulnerability Assessment and Adaptation Planning project. Major tasks accomplished during this phase of the project include 1) selecting a model and determining the tidal, sea level rise and surge parameters, as well as choosing which out years and storm probabilities with which to evaluate specific risks, and 2) collecting relevant datasets to compile an initial list of municipal assets.

1. Selection of model and determination of input parameters The hydrodynamic modeling utilized for this study simulates a full suite of processes that affect coastal water levels, including , waves, winds, storm surge, sea level rise, and wave set-up at a fine enough resolution to identify site-specific locations that may require adaptation alternatives. Water surface elevations were modelled using the ADvanced CIRCulation (ADCIRC) software to predict storm surge flooding coupled with the Simulated WAves Nearshore (SWAN) software, a wave generation and transformation model. This modeling was performed as part of the Coast Flood Risk Model (MC-FRM), which was developed for the Massachusetts Department of Transportation (MassDOT) to assess potential flooding vulnerabilities to highways and other transportation infrastructure throughout the state of Massachusetts. Since the MC-FRM domain includes the entire Massachusetts coastal area, including the Town of Falmouth, this model is ideally suited to assess the vulnerability and risk of coastal flooding to Falmouth’s infrastructure and natural resources. Using this existing model is beneficial to the Town of Falmouth since much of the upfront work and cost in developing the model was already conducted as part of the MassDOT project.

The spatial resolution of the model is 10 meters or less between nodal points, and sometimes as low as 2-3 meters to capture important changes in topography and physical processes related to storm dynamics. This high-resolution model offers more accuracy than other storm surge models, such as the Sea, Lake, and Overland Surges from Hurricanes (SLOSH) model developed by the U.S. Army Corps of Engineers (USACE) and the National Oceanic and Atmospheric Administration (NOAA). The MC-FRM is also superior to a more rudimentary “bathtub” approach, since the latter does not account for critical physical processes that occur during a storm event, including waves and winds, nor can it determine the limited volume of water that may be able to enter certain areas, particularly those with narrow entry points.

The model quantitatively incorporates climate change influences on sea level rise, tides, waves, storm track, and storm intensity for 2030, 2050, 2070, and 2100 time horizons, providing discrete risk estimates at various time horizons to assist with both near- and long-term planning. To do so, it evaluates a statistically-robust sample of storms, including hurricanes, tropical storms and nor’easters, based on the region’s existing and evolving climatology. Using this storm set, the model then calculates resulting water elevations to estimate the probability that different flood depths will be exceeded at each nodal point within the model boundary. The resulting flood risk maps and probability curves can then be interpreted using geographic information systems (GIS) to identify the estimated annual probability, or likelihood, that any node within the model will experience flooding, and if so, up to what elevation.

The probability-based approach of the proposed modeling will be beneficial to the Town when assessing the vulnerability of and risk to infrastructure and when developing adaptation strategies to mitigate future flooding damage. It will also produce information that can be used to inform engineering design criteria since it provides the probability of an event occurring in this changing regime, such as the “new” 1% event flood levels (equivalent to a 100 year recurrence water level). In particular, an accurate and precise assessment of the exceedance probability of combined SLR and storm surge is provided that can help Town managers and decision makers identify areas of existing and near-term vulnerability requiring immediate action in Falmouth, as well as areas that will benefit from long-range planning for future preparedness and risk reduction.

The relative sea-level rise (RSLR) projections used in the MC-FRM represent the most up-to-date RSLR projects for the Massachusetts coastline (Douglas et al., 2016, Climate Change and Sea Level Rise Projections for ), drawing on long-term water level datasets from a series of gages around the state. For Falmouth, RSLR was estimated using the local NOAA tidal gage at Woods Hole (station ID 8447930), which has recorded an increase in relative mean sea level of 2.86 mm (+/- 0.17 mm) annually based on monthly mean sea level data from 1932 to 2017 (Figure 1). This equates to approximately 9.5 inches of mean sea-level rise over the last 85 years. Over that same time period, the global rate of sea level rise was about 1.7 mm annually (approximately 5.7 inches over the last 85 years). This significant difference between the RSLR experienced locally and the global SLR trend highlights the importance of accounting for local conditions.

In order to compare future mean sea level to “present day” conditions, a starting elevation for mean sea level must be calculated. A tidal-epoch, a 19-year time period, is traditionally used to calculate tidal datums. For this study, the 19-year tidal-epoch with a mid-point year of 2000 (i.e., 1991-2009) was used to calculate a starting elevation for mean sea level. Based on this methodology, the mean sea level in Falmouth in the year 2000 was at an elevation of -0.30 feet (NAVD88). This 2000 starting elevation of -0.30 feet (NAVD88) can then be used to compare to projected relative mean sea-level elevations at 2030, 2050, 2070 and 2100 under various scenarios (Table 1). Note that the values in Table 1 are elevations of the projected mean sea level at various times relative to a vertical datum of NAVD88, not the magnitude of change in elevation. For comparison, the baseline (i.e., year 2000) mean sea level elevation, is -0.30 feet (NAVD88). Based on the projected sea level elevations presented in Table 1, this means there is a projected change in mean sea level rise of 1.4, 2.7. 4.5 and 8.0 feet between the year 2000 and 2030, 2050, 2070 and 2100, respectively, based on the “High” SLR scenario.

The data in Table 1 are recommended by Massachusetts CZM for assessing sea-level rise, and are being used by the Massachusetts Department of Transportation and other state agencies and communities for vulnerability assessments. As such, these sea-level rise projections were incorporated into the MC-FRM. The “High” SLR scenario was chosen for the MC-FRM because MassDOT and the state were interested in inundation risk probabilities that were unlikely to be exceeded (there is a 99.5% confidence level that the “High” scenario chosen will not be exceeded). In addition, selecting the “High” scenario also allows for the evaluation of inundation risk probabilities under other scenarios due to the bracketed nature of the results. For example, the “High” results in 2030 are equivalent to “Intermediate” results in 2050, and the “High” results in 2050 are the equivalent to the “Intermediate” results in 2070. In this way, the selected scenarios provide an upper bound of potential risk.

The Town of Falmouth Climate Change Vulnerability Assessment and Adaptation Planning project will focus on two of the modeled out-years for climate change, sea-level rise and storm surge flood effects: 2030 and 2070. These out-years were selected by a Steering Committee, comprised of multi-departmental working group of municipal staff and committee members, to provide the most useful data for planning (see Appendix A for a list of Steering Committee members). Flood risk probabilities for 2030 represent a near-term risk, which will be useful in driving actionable items now, while flood risk probabilities for 2070 will provide a long-range planning tool that will be particularly useful when planning large capital projects, designing and siting new infrastructure and/or buildings, and guiding municipal bylaws and zoning regulations.

Probability of flooding will be evaluated at 2030 and 2070 time horizons.

Probability-based inundation maps will be developed for both of the selected out-years (2030 and 2070). In addition, depth of inundation maps will also be developed for two probability levels. The Town Steering Committee selected the 1% event flood levels (equivalent to a 100-year recurrence water level) and the 5% event flood levels (equivalent to a 20-year recurrence water level) for which to develop these depth of inundation maps. The 1% probability level was selected because this is the benchmark for the Federal Emergency Management Agency’s (FEMA’s) Flood Insurance Rate Maps (FIRMs). Although FEMA FIRMs are not forward-looking and do not incorporate sea-level rise into the mapping, FEMA does periodically update their modeling to account for increased sea level rise that has occurred (as well as other changes, such as changes in topography or armoring of particular areas). As such, the 2030 and 2070 1% probability of inundation extents may provide a projection for the expected future FEMA flood zones.

The second probability level chosen for development of depth of inundation maps was the 5% event flood levels. Although some municipalities are interested in the worst case scenario (e.g., the 0.2% [500-year] or the 0.1% [1000-year] water level), the Falmouth Steering Committee decided that it would be most useful for the Town to plan for the depth of flooding likely to occur during a more probable storm event.

Depth of flooding maps will be created for the 1% and 5% probability levels.

2. Collect municipal asset data A risk-based vulnerability assessment will be performed in the second Phase of this project to evaluate the flood risk to municipally-owned assets. This Phase of the project focused on developing a thorough municipally-owned asset list that will be used for the vulnerability assessment. The landward extent of the MC-FRM grid is set at an elevation of 8 meters (26.2 feet) NAVD88. Because much of the northeastern part of Town is higher than this elevation, this area is excluded from the model (Figure 2), and any Town-owned asset within it will be screened out from further analysis, since it would have no risk from coastal flooding through 2100. An elevation of 8 meters was chosen as an inland extent because this elevation is well above the projected extent of inundation even during a large storm in 2100.

Woods Hole Group worked cooperatively with the Steering Committee to compile existing GIS-based data and information about locations of Town assets. Based on discussions with the Steering Committee, the following Town-owned assets within the model extent (Figure 2) will be included in the vulnerability assessment: • Buildings and structures (85) o Including above ground utilities (e.g., wastewater lift stations) • Parking lots (58) • Boat ramps (8) and docks (26) • Recreational facilities (e.g., baseballs fields, tennis courts, etc.) (35) • Shining Sea Bike Path (10 sections) • Coastal infrastructure (e.g., seawalls, jetties, groins, etc.) (91) • Trunk river sewer main section • Roads/bridges (all within model grid)

For a full list of municipally-owned assets that will be included in the vulnerability assessment, see Appendix B.

In addition to the built assets listed above, impacts to natural resources including , coves and salt marshes, will be assessed on a semi-quantitative basis. Woods Hole Group will draw from the data developed for the Massachusetts Office of Coastal Zone Management (CZM) to model the effects of sea-level rise on coastal wetlands and natural resources statewide. The software Sea Level Rise Affecting Marshes Model (SLAMM) was used to assess the impacts to natural resources for that project. Final model results for the 2030 and 2070 out years for the “High” SLR projection will be incorporated into this study.
