1 The Citadel Multi-Hazard Mitigation Disaster Resistant University Plan

2 Project Objective To Develop a Disaster Resistant University Hazard Mitigation Plan Identify Hazards Profile Hazards Inventory Assets Estimate Losses Develop a Mitigation Strategy

3 University Background

4 History Founded in 1842 as the South Carolina Military Academy Citadel Academy in Charleston Arsenal Academy in Columbia Originally located on Marion Square One of six senior Military Colleges in the U.S. Moved to current location in 1922 City of Charleston offered 176 acres to State State supported comprehensive college 5 schools Business Education Engineering Humanities and Social Sciences Science and Mathematics

5 Campus Profile Located on the peninsula adjacent to the Ashley River Average campus ground elevation is 10.3 feet above sea level ~2,300 cadets ~1,200 graduate students 78 campus buildings 7 occupancy types Estimated $1Billion in assets

8 Challenge: Lack of Campus Data

9 Solution: Creation of Campus Base Map

10 Challenge: No Digital FIRM The image cannot be displayed. Your computer may not have enough memory to open the image, or the image may have been corrupted. Restart your computer, and then open the file again. If the red x still appears, you may have to delete the image and then insert it again.

11 Solution: Digitized Flood Layer

12 Hazus Runs

13 Hazus Runs Flood Hurricane Earthquake

14 Assets at Risk *Agricultural building is campus green house

15 Flood Depth/Damage Curve Flood damage is directly related to the depth of flooding by the application of a depth damage curve. In applying the curve, a specific depth of water translates to a specific percentage of damage to the structure, which translates to the same percentage of the structure s replacement value.

18 Sea Level Rise To determine the specific variation in loss estimates based on flood severity and sea level rise, impacts of coastal flooding were assessed using Hazus and the impact of the 100-year coastal flood on the Citadel campus with 1.08 feet of sea level rise (expected by 2050).

28 Mitigation Strategy

29 Mitigation Actions Develop GIS Capabilities Action Develop a system to ensure that new students, faculty, and staff are exposed to basic all-hazards preparedness training during orientation activities. Improve/upgrade stormwater drainage features Conduct survey of all campus facilities that store hazardous materials to identify non-structural components (i.e. shelving and storage areas) that may be vulnerable to earthquake damage.
