Introduction In 2006, The Nature Conservancy established the Coastal Resilience Program (www.coastalresilience.org) that provides tools and a solution framework to reduce the ecological and socio-economic risk of hazards and comprehensively improve community resilience along the Connecticut coast. The Program focuses on helping decision-makers explore locally relevant, downscaled, flooding scenarios from sea-level rise and/or storm surge, analyze the potential ecological, social and economic impacts of each scenario at a local, regional, and state scale, and facilitate solutions to address these issues. Since 2006, The Nature Conservancy has directly assisted over 35 coastal and inland communities in Connecticut through the provision of this critical information coupled with a comprehensive, community-based process that improves overall resilience and sustainability. There is a universal recognition by coastal and inland communities in Connecticut and elsewhere that natural infrastructure such as wetlands and forests - is a cost effective, long-term part of the solution that will protect people, infrastructure and natural systems from extreme weather and climatic change. Fortunately, our state has a remarkable diversity and abundance of natural resources that provide habitat for wildlife and fisheries, enhance the aesthetics and quality of life for residents, and, of course, defend the shoreline and rivers against storm surge, inland flooding, and sea level rise. The presence of natural infrastructure across the state in particular salt marsh, beaches/dunes, forested headwaters, and river floodplains is a testament of previous recognition and commitment to long-term conservation and the requisite balance with socio-economic growth. In order to maintain this natural infrastructure it will require 1) routine and on-going management activities as well as the restoration of degraded areas, 2) forward-looking planning to accommodate changes in habitat composition and location due to climatic change and 3) enforcement, modification and/or establishment of new land use policies and growth strategies. Opportunities also exist to account for and integrate the services or co-benefits provided by natural infrastructure via new development, redevelopment, or realignment activities. Economically important co-benefits from natural infrastructure include wave attenuation, improved water storage and filtering of pollutants from surface runoff, erosion control, and improved aesthetics and desirability of public amenities. Taken in total, the immediate and longer-term management of natural infrastructure by the state, towns, private property owners, non-profit organizations and others will help to reduce risk and improve resilience across the entirety of Connecticut. While longer-term changes in temperature and precipitation patterns will alter the species composition and type of habitats in a given location, the more immediate implication is the upslope advancement of habitats such as salt marsh in response to continued sea level rise. Sea level rise and the impacts of flooding have and will continue to alter the presence and abundance of natural infrastructure in Connecticut. One of the most noticeable changes is occurring at the coastal edge where salt marsh is in the process of advancing upslope into areas now considered uplands. In order to clearly identify where this will occur along Connecticut s coast, The Nature Conservancy presents the following report to assist with future planning for natural infrastructure in the context of overall risk reduction and resiliency improvement for coastal communities. Ultimately, it is our hope that this report will serve to inform Page 2

communities about future marsh advancement locations, current land use of those locations and which parcels are critical to ensure the persistence of natural infrastructure in Connecticut longer term. The Salt Marsh Advancement Model used in this analysis was co-developed by The Nature Conservancy and the University of Connecticut s Department of Natural Resources Management and Engineering. A full discussion of the Model and underlying methodology is beyond the scope of this report, but a few important details are needed to put the following analysis into context and define how to use the results for planning and implementation. Suitable vs. Unsuitable Advancement In the following figures and tables suitable advancement areas are abbreviated as Yes and unsuitable areas are abbreviated as No. Suitable areas are classified based on the current land cover type - forest or agrigrass - and as such are expected to convert to salt marsh as hydrologic conditions change due to sea level rise, in the absence of further land use change. Land cover types classified as urban (i.e. roads, buildings, runways, parking lots, etc.) are considered to be unsuitable for salt marsh advancement at this time. Though much of our analysis is grouped by parcel ID and associated characteristics, these classifications suitable and unsuitable exist independent of the parcel boundaries. In other words, a given residential parcel can have both suitable (lawn) and unsuitable (building footprint) advancement areas. Marsh Advancement vs. Wetland Extent There is a key distinction in this report between the current wetland extent in a municipality and the marsh advancement areas analyzed herein. Marsh advancement areas include only the future projected wetland extent clipped to current upland land cover. Therefore, no assumption should be made about net gain or loss of current wetland extent based on this advancement area analysis. Another key consideration is that in some cases the identified advancement area will include land that converts to wetlands and subsequently to open-water over time. This further demonstrates that net change in both existing and future wetland extent should not be inferred from our analysis. Planning for the Future The advancement and eventual establishment of salt marshes will occur over the course of several decades and as such our analysis extends out to the 2080s. The rate of change is slow and decadal, yet inevitable. There is an abundance of existing property, infrastructure and natural assets clustered along the Connecticut coast and communities will need to formulate growth and realignment plans well in advance of the 2080s scenario presented here. The following data analysis and associated Map Book (Appendix) can assist with a resilient transition through the presentation of salt marsh advancement areas and an accounting of the projected changes to coastal property. Page 3

Total Marsh Advancement The full extent of marsh advancement in Connecticut by the 2080s is projected to be 23,928.8 acres, with 16,891.8 acres (70.6%) having suitable (Yes) land cover for salt marsh advancement. The other 7,037.0 acres (29.4%) are occupied by built structures and associated infrastructure and are unsuitable for marsh advancement (No), currently. Total Marsh Adv Acres Percent (%) Yes 16,891.8 70.6 No 7,037.0 29.4 Total 23,928.8 100.0 Marsh Advancement by Municipality Connecticut s coastal municipalities provide varying proportions of the state s full extent (Yes + No) and suitable (Yes only) marsh advancement. The table below outlines the distribution of the full extent of marsh advancement and suitable marsh advancement by municipality from greatest to least. Full Extent (Yes + No) Marsh Advancement Suitable (Yes) Marsh Advancement Municipality Acres Full Extent (%) Municipality Acres Suitable (%) Stratford 2,384.6 10.0 Stonington 1,731.3 10.2 Stonington 1,999.5 8.4 Stratford 1,279.0 7.6 New Haven 1,675.0 7.0 Groton 1,172.6 6.9 Groton 1,470.5 6.1 Fairfield 1,026.3 6.1 Fairfield 1,401.9 5.9 Branford 924.2 5.5 Milford 1,162.6 4.9 Milford 867.0 5.1 Branford 1,138.3 4.8 Old Saybrook 825.2 4.9 Bridgeport 1,136.1 4.7 New Haven 820.7 4.9 Norwalk 1,103.4 4.6 Old Lyme 813.6 4.8 Old Saybrook 1,042.0 4.4 Guilford 754.0 4.5 East Haven 941.2 3.9 Madison 720.4 4.3 Old Lyme 937.9 3.9 East Haven 683.5 4.0 Guilford 927.5 3.9 Greenwich 681.0 4.0 Madison 916.7 3.8 Westport 667.1 3.9 Westport 885.3 3.7 Norwalk 657.9 3.9 Greenwich 876.0 3.7 Clinton 518.3 3.1 Stamford 863.8 3.6 Bridgeport 467.8 2.8 Clinton 650.1 2.7 Stamford 435.4 2.6 Westbrook 556.4 2.3 Darien 415.9 2.5 Darien 506.5 2.1 Westbrook 380.5 2.3 West Haven 503.6 2.1 West Haven 374.1 2.2 East Lyme 365.6 1.5 East Lyme 325.5 1.9 Waterford 330.3 1.4 Waterford 293.5 1.7 New London 154.0 0.6 New London 57.0 0.3 Total 23,928.8 100.0 Total 16,891.8 100.0 Page 4

Marsh Advancement in Open Space Open space (OS) properties are a critical component of long-term community resilience because they currently have little to no development and are the most likely areas to remain undeveloped through the 2080s. The recognition of the role of these parcels in future marsh extent and improved resilience in Connecticut is vital for strategic land management, economic development, and planning. Total Advancement in Open Space The following three categories are considered in this section: Yes OS: Areas of open space suitable for marsh advancement No OS: Areas of open space unsuitable for marsh advancement Non-OS: Unprotected areas both suitable and unsuitable for marsh advancement Open space parcels in Connecticut contain 6,587.3 acres of total marsh advancement area with 5,619.5 acres (23.5% of total) having a land cover suitable for future wetlands (Yes OS). Further analysis of the 17,341.5 acres of unprotected parcels (Non-OS) can be found in the following Marsh Advancement in All section. Open Space Marsh Advancement OS type Acres Yes OS 5,619.5 No OS 967.8 Non-OS 17,341.5 Total 23,928.8 Open Space Marsh Advancement 23.5% Yes OS 4.0% No OS 72.5% Non-OS Page 5

Suitable Open Space Advancement by Owner Municipalities own the greatest share of suitable open space for marsh advancement accounting for 2,393.0 acres (42.6%). State open space parcels provide 1,336.1 acres (23.8%). Privately owned properties contribute 1,028.2 acres (18.3%). Federal open space accommodates 196.7 acres (3.5%). Lastly, open space owned by utilities provides just 2.9 acres (0.1%) of Connecticut s future marsh advancement area.

Marsh Advancement in All This section incorporates all parcels into the analysis of suitable marsh advancement. These results help put the open space analysis into perspective, as well as identify important unprotected parcels in Connecticut s marsh advancement landscape. Total Advancement in All (OS vs. Non-OS) The open space parcels for this analysis include many types of properties including state parks, municipal open space, cemeteries, conservation non-profit properties, open space set-asides for developments, and other private properties. This section provides an analysis of suitable areas for marsh advancement on these open space parcels versus all other parcels. These two types of parcels are designated as: OS for open space parcels Non-OS for all other parcels Open space parcels contain 5,619.5 acres (33.0% of total) of suitable marsh advancement zone. The other 11,272.3 acres of land suitable for marsh advancement (67.0% of total) are unprotected and generally occur on residential, commercial, or industrial properties. The unprotected suitable areas will receive twofold of Connecticut s marsh advancement by the 2080s. This information has two important implications for future planning: 1) today s unprotected properties will play a vital role in maintaining Connecticut s salt marsh resources in the future, and 2) a large amount of current development (6,069.2 acres) will be in direct conflict with rising sea levels. 20,000 Total Marsh Advancement in All 15,000 Total Marsh Advancement Parcel type Yes No Total Acres 10,000 No Yes OS 5,619.5 967.8 6,587.3 Non-OS 11,272.3 6,069.2 17,341.5 5,000 Total 16,891.8 7,037.0 23,928.8 0 OS Non-OS Page 8
