1/24/2007 Chenango County Requirements for Local Mitigation Plans � Be prepared by November 1, 2004 � Include the opportunity for public comment and for relevant agency and stakeholder involvement � Risk Assessment - a factual basis for activities proposed in the Mitigation Strategy section include: Overview of hazards (type, location, probability) – Vulnerability analysis (impact on buildings, infrastructure, economy, – development trends) Multiple jurisdictions (specific to each town/village/city) – � Mitigation Strategy – a blueprint for reducing losses identified in the risk assessment � Plan Maintenance and Adoption Processes 1/24/2007 4 Chenango County Mitigation Planning and HAZUS-MH Phase 1: Organize Resources HAZUS-MH Applied to Conduct Risk Phase 2: Assess Risks Assessment Using Four Risk Assessment Steps Phase 3: Develop the Mitigation Plan Results from HAZUS-MH Phase 4: Implement the Plan and Monitor Progress 1/24/2007 5 Chenango County Risk Assessment Using HAZUS-MH Risk Assessment Steps HAZUS-MH Outputs Base map, list of hazards Step 1: Identify Hazards of concern Table of hazard profile Step 2: Profile Hazard data, map of hazard Events areas, list of priority Tables and maps of hazards Step 3: Inventory Assets inventory data Specific loss estimation Step 4: Estimate Losses outputs: tables, maps, summary text Application: Use HAZUS-MH Risk Assessment Outputs 1/24/2007 6 2
1/24/2007 Chenango County Hazard Identification and Profiling What hazards pose the greatest threat to Chenango County? � We want to identify our “hazards of concern” that we will carry through the – planning process. Our effort should be proportional to the risk the hazards pose. – We are limiting this plan to natural hazards. – County conducted a Hazards-New York (HAZNY) analysis in November, � 2004. We will go through this exercise today. Hazards are profiled (characterized) according to: � Background and local conditions – Historic frequency and probability of occurrence – – Severity Historic losses and impacts – Designated hazard areas – Where do we get this data? � NOAA, NWS, USDA, USACE, FEMA, NYSEMO, Regional, County and Local Agencies Challenge: Identifying losses at the County and Local level 1/24/2007 7 Chenango County Inventory of Assets What is at risk? People, Property, Economy, Environment � Population and Demographics � Building Stock (Residential, Commercial, Industrial, Educational, etc.) � Critical Facilities – Police, Fire, Emergency Services – Hospitals and Medical Care Facilities – Schools and Care Facilities – Sheltering Facilities – Infrastructure (Transportation Systems, Utilities) – High-Potential Loss Facilities (Dams, Military Installations, Haz-Mats) 1/24/2007 8 Chenango County Risk Assessment – Vulnerability Analysis The Risk Assessment overlays your inventory with your hazards to determine potential losses (vulnerability). Example: Per the State Plan, Chenango County has 1,876 residential properties (10% of total) in the 100-year floodplain, with a structural value estimated at $102 million. If an average house suffers damage amounting to 25% of it’s value in a 100-year flood: ($102 Million * 15%)/100 years = $255,000/year 1/24/2007 9 3
1/24/2007 Chenango County 1/24/2007 10 10 Chenango County Developing Mitigation Strategies � Develop Hazard Mitigation Goals and Objectives Goals : General guidelines that state what we want to achieve. Should be consistent with the State goals and other local goals. Example: “Protect existing properties.” Objectives : Define strategies or implementation steps to attain a stated goal. Example: “Enact or enforce regulatory measures that ensure new development will not increase flood threats to existing properties”. � Conduct Capability Assessments “Proposed mitigation actions will be evaluated against the backdrop of what is feasible in terms of your government’s legal, administrative, fiscal and technical capacities” (FEMA 386-3) Serve to identify legal authority and administrative, technical and fiscal capabilities in the – state, county and jurisdictions that will facilitate or hinder hazard mitigation goals and objectives. State Capability Assessment is in the State HMP – 1/24/2007 11 11 Chenango County Identification and Analysis of Mitigation Actions � Mitigation strategies need to be realistic, achievable and action-oriented. � Will include both regional (county-wide) strategies, as well as jurisdiction- specific. � For each proposed mitigation strategy, the following will be identified: Implementation timeline – Estimated budget – Potential funding sources – Lead agency or department – Supporting agencies – � Proposed mitigation activities are evaluated using a Cost-Benefit Analysis or STAPLEE criteria S ocial, T echnical, A dministrative, P olitical, L egal, E conomic, E nvironmental 1/24/2007 12 12 4
1/24/2007 Chenango County Other Planning Tasks � Assuring wide involvement and public participation Notices and new releases on planning effort (mass media – Evening Sun, – New Berlin Gazette) HMP Webpage detailing effort, providing downloadable drafts of the plan, – and providing a way for public input (local contact information and email link) Public presentations and meetings – Public access to draft and final plan documents (incl. libraries, town halls) – Questionnaire – � Documentation of the Planning Process � Plan implementation and maintenance procedures � Adoption by local governments 1/24/2007 13 13 Chenango County Plan Document We are proposing the use of a two-volume approach: � Volume 1 will contain all information that applies to the whole planning area (county) such as description of the planning process, risk assessment, goals and objectives, County/multi-jurisdictional mitigation strategies and a plan maintenance program. � Volume 2 will contain those elements that are “jurisdiction specific”. Volume 2 would include a jurisdictional annex for each participating local government within each county. These annexes will meet DMA requirements for each jurisdiction. 1/24/2007 14 14 Chenango County Planning Partner Expectations � Attend meetings � Provide data and information in a timely manner � Facilitate public and stakeholder outreach in your jurisdiction � Assist in the development of mitigation goals and objectives � Provide past, present and proposed mitigation actions for your jurisdiction � Author your jurisdictional annex � Review and provide feedback on draft plan documents 1/24/2007 15 15 5

1/24/2007 Chenango County Flood (Flash and Riverine) 1/24/2007 19 19 Chenango County Flood (Flash and Riverine) Definitions: � HAZNY: When a waterbody overflows its “normal” banks. Flash flood is a sudden transformation of a small stream into a violent waterway after a heavy rain or rapid snowmelt (modified “and occurs in less than six hours of the onset of the storm”). FEMA: A general and temporary condition of partial or complete inundation of � normally dry land areas from (1) the overflow of inland or tidal waters, (2) the unusual and rapid accumulation of runoff or surface waters from any source. (modified in State Plan to include “…a situation in which rainfall is so intense and severe and runoff so rapid that it precludes recording and relating it to stream stages and other information in time to forecast a flood condition.) NFIP Statistics for Chenango County (to 11/30/2006) 566 policies insuring $56.9 M property – 378 claims totaling $4.8 MM – – 3 Repetitive Loss Properties – No jurisdictions participating in CRS Per the State Plan, Chenango County has 1,876 residential properties (10% of total) in the 100-year floodplain, with a structural value estimated at $ 102 million. This suggests only 1/3 to ½ have flood insurance. 1/24/2007 20 20 Chenango County Severe Storm (wind, including tornado?) 1/24/2007 21 21 7
