1 WEATHER IT TOGETHER The Annapolis Model for Cultural Resource Adaptation Planning Cultural Resources, Disaster Resilience, and Climate Uncertainty

2 Historic Annapolis A Colonial Capital: National Landmark District (1965) Nicholson plans Colonial Capital St. John s College (3 rd oldest in U.S.) Alex Haley s Kunta Kinte arrives Lord Ligonier State House (oldest continuous operating) Home to Maryland s 4 signers General Washington Resigns Commission First peacetime Capital to 1784 U.S. Naval Academy established

3 Protecting Our Historic Seaport FEMA Hazard Mitigation Planning Hazard mitigation planning is the process of determining how to reduce or eliminate the loss of life and property damage resulting from natural and manmade hazards. 1. Organize efforts to develop a mitigation plan; 2. Identify hazards and assessing losses to your community; 3. Set priorities and goals and write the plan; 4. Implement the mitigation plan, including project funding.

4 Organize Resources Research: Flood Mitigation Studies Focus on protecting existing structures Study downtown to determine the costs and benefits of public decisionmaking in mitigating property damage Evaluate the need and options for protecting historic structures Require floodproofing to the extent feasible

5 Organize Resources Research: Comprehensive & Master Plans In conjunction with the development of a Hazard Mitigation Plan to protect historic resources the City will explore and present to the City Council for consideration

6 Organize Resources Build the Planning Team Organize your efforts to develop an effective mitigation plan bringing together the appropriate planning team, consultants, technology, community support and financial resources.

7 Organize Resources Utilize the Necessary Technology (GIS) Develop a database of historic survey, risk assessment and elevation information for City Dock and Eastport cultural resources.

8 Organize Resources Secure the Necessary Financial / In-Kind Resources Maryland Historical Trust/SHPO ($25,000) National Trust for Historic Preservation ($25,000) Preservation Maryland ($4,000) MD Dept. of Natural Resources/NOAA ($48,000) Urban Land Institute, Baltimore Chapter ($20,000) USACE (est. $120,000+ in-kind) MEMA/FEMA ($106,000) National League of Cities ($10,000+)

9 Identify Hazards Identify & Map the Floodplain Study Area

10 Step #1 Organize efforts to develop a mitigation plan 1. What documents will you research to determine existing efforts to protect historic properties and cultural resources from natural disasters / threats? 2. How will you assess the level of support that exists in your community for protecting historic assets? 3. Who would you included on your planning core team? 4. What community outreach approaches can you use to engage the public in your planning process?

11 Identify Hazards / Survey Conduct a Cultural Resource Survey Worksheet #3 Name/Address of Resource Date of Construction Type of Property Square Footage Structural System Primary Materials Current Function Current Condition Owner Interest in Mitigation

12 Survey / Assess Risks Assess Property Vulnerability 147 Properties Property Vulnerability (High, Med, Low) Loss to Structure ($) Loss to Contents ($) Loss of Function / Use ($) Displacement Cost ($) Total Projected Loss/Cost - $268.5 million 1 Event / 12 Months

13 Survey / Assess Risks Complete a Non-Structural Mitigation Assessment Crisfield, Somerset County MD

14 Step #2 Identify hazards and assess losses to your community 1. What hazards affect your community? 2. What are your hazard-prone areas? 3. What historic properties and cultural resources are vulnerable to each hazard type? 4. How will you determine which historic assets are most valuable to the community? 5. How will you determine your preservation hierarchy for historic properties and cultural resources for protection in the community?

15 Set Priorities Determine Community Value Worksheet #4 Historic Designation (NR, Local) Geographic Context of Significance Level of Significance (H/M/L) Public Sentiment (H/M/L) Economic Importance (H/M/L Degree of Integrity (H/M/L) = Total Level of Community Value

16 Set Priorities Assess Public Sentiment Visual Preference Survey

17 Set Priorities Assess Public Sentiment Response

18 Write the Plan Establish Goals & Objectives Goal #1: Public and private property owners in Annapolis will incorporate hazard mitigation improvements into their routine maintenance, repair and rehabilitation projects to protect cultural resources from tidal flooding, sea level rise and other natural disasters.

19 Write the Plan Adaptation: Land Use Planning & Building Codes Density controls Design Review Standards Easements Floodplain Overlay Zoning Open Space Preservation Special Use Permits Subdivision & Development Regulations Transfer of Development Rights Environmental Review Standards Building Codes Coastal Zone Management

20 Write the Plan Adaptation: Public Education & Engagement Website / Social Media Branding High Water Markers Interpretive Kiosks Videos Media Publications

21 Write the Plan Adaptation: Public Engagement Planning Charrette

22 Write the Plan Adaptation: Natural Resource Protection Before - Erosion After Living Shoreline

23 Write the Plan Adaptation: Dry Floodproofing Sealing building walls with waterproof compounds and using shields (dams or perimeter barriers) to seal off doors, windows and other openings to keep the building watertight. This technique can only be used when the walls are strong enough to withstand the hydrostatic force of the water. Door & Window Dams

24 Write the Plan Adaptation: Barriers Permanent Flood Wall Temporary Door Dam Temporary Flood Wall Backflow Preventers

25 Write the Plan Adaptation: Elevation Elevation may alter the appearance and scale of a historic building and redefine its relationship to its setting. If the building is raised only several feet, elevation should not alter scale. A preservation-sensitive alternative would be elevation of floors within the building, feasible in historic commercial structures with tall ceilings.

26 Step #3 Set Priorities and Goals and Write the Plan 1. State one goal, objective and action that you will move forward in your community as a direct result of this workshop. A Goal is a general guideline that explains what you want to achieve. This is usually a broad policy statement that represents a long-term, global vision. Our community will develop ways to protect significant historic properties and cultural resources from future flood events. An Objective is a defined strategy or implementation step for attaining the identified goals. Unlike goals, objectives are measurable. Protect structures in the historic downtown area from flood damage. A Mitigation Action is a specific action that helps you achieve your goals and objectives. Elevate three historic structures located in the historic district.

27 Implement the Plan Adaptation: Floodwalls Seek FEMA funding for model adaptation projects for priority properties in floodplain area. Work with Naval Academy to protect 4,500 linear feet of shared shoreline. Work with USACE to design for installation of backflow prevents at each sewer connection. Secure funding for floodwalls, coffer dams, pumping station, temporary pumps and valves.

28 Implement the Plan Adaptation: Economic Policies & Incentives City property tax credit applied to certified expenses for hazard mitigation / adaptation equal to 25% of rehabilitation cost on residential and income-producing properties (including interior improvements)

29 St. Michaels, Talbot County Implement the Plan Promote the Planning Methodology MHT is funding the project in part so that we can use it as a model for other communities throughout the state that have cultural resources threatened by sealevel rise.

30 Weather It Together Protecting Our Historic Seaport Maintain Preserve, protect and prepare your property Mobilize Create and share resources that educate, inform and incentivize your community Mitigate - Eliminate or reduce impacts and risks of hazards through pre-disaster planning in your community Monetize Protect and enhance the value of your building, business, and community through building resiliency Every $1 spent on mitigation saves society an average of $4. National Institute of Building Sciences

31 Weather It Together Maintain: Preserve, protect and prepare your property Identify three tools you believe could work best in your community to encourage the maintenance of historic properties. Remember the Adaptation Alternatives Land Use Planning & Economic Development Building Codes & Regulations Cultural Resource Protection Natural Resource Protection Private Property Improvements Public Property Improvements Public Awareness Economic Incentives

32 Weather It Together Mobilize: Create and share resources that educate, inform and incentivize your community Identify three ways you can share information with your community to realize greater public awareness and response to flooding.

33 Weather It Together Mitigate: Eliminate or reduce impacts and risks of hazards through pre-disaster planning in your community What will you commit to as your first step on the path to building greater resiliency in your community?

34 Weather It Together Monetize: Protect and enhance the value of your building, business, and community through building resiliency List one economic incentive your community could adopt to encourage greater resiliency for your historic resources.

35 Weather It Together Building Resilience Resilience is the capacity of individuals, communities and systems to survive, adapt, and grow in the face of stress and shocks, and even transform when conditions require. Building resilience is better preparing people, communities & systems to withstand catastrophic events - natural or manmade and bounce back more quickly, emerging stronger.
