PRC.15.1.1 a Publication of AXA XL Risk Consulting
Property Risk Consulting Guidelines PRC.15.1.1 A Publication of AXA XL Risk Consulting WINDSTORMS INTRODUCTION A variety of windstorms occur throughout the world on a frequent basis. Although most winds are related to exchanges of energy (heat) between different air masses, there are a number of weather mechanisms that are involved in wind generation. These depend on latitude, altitude, topography and other factors. The different mechanisms produce windstorms with various characteristics. Some affect wide geographical areas, while others are local in nature. Some storms produce cooling effects, whereas others rapidly increase the ambient temperatures in affected areas. Tropical cyclones born over the oceans, tornadoes in the mid-west and the Santa Ana winds of Southern California are examples of widely different windstorms. The following is a short description of some of the more prevalent wind phenomena. A glossary of terms associated with windstorms is provided in PRC.15.1.1.A. The Beaufort Wind Scale, the Saffir/Simpson Hurricane Scale, the Australian Bureau of Meteorology Cyclone Severity Scale and the Fugita Tornado Scale are also provided in PRC.15.1.1.A. Types Of Windstorms Local Windstorms A variety of wind conditions are brought about by local factors, some of which can generate relatively high wind conditions. While they do not have the extreme high winds of tropical cyclones and tornadoes, they can cause considerable property damage. Many of these local conditions tend to be seasonal. Cold weather storms along the East coast are known as Nor’easters or Northeasters. While their winds are usually less than hurricane velocity, they may create as much or more damage. -
Example Language for Identifying Sea Level Rise and Coastal Hazards Information Necessary for a Complete CDP Application
STATE OF CALIFORNIA—NATURAL RESOURCES AGENCY EDMUND G. BROWN, JR., GOVERNOR CALIFORNIA COASTAL COMMISSION 45 FREMONT STREET, SUITE 2000 SAN FRANCISCO, CA 94105- 2219 VOICE (415) 904- 5200 FAX ( 415) 904- 5400 TDD (415) 597-5885 To: Coastal Commission District Staff, Coastal Planning Departments From: Kelsey Ducklow, Coastal Commission, Statewide Planning Unit Date: January 3, 2019 Re: Example language for identifying sea level rise and coastal hazards information necessary for a complete CDP application Purpose This memo is intended to provide coastal analysts with information and example language that can be used in a non-filing/incomplete letter (or to gather information prior to submittal of a CDP application) when asking for an analysis of coastal hazards and sea level rise from an applicant. This language is generally similar to the information coastal analysts have requested in the past to be included in technical studies that analyze potential impacts from coastal hazards, but includes additional detail on how to incorporate sea level rise into those analyses. Please note that the information and example language below pertains only to the coastal hazards-related portion of a CDP application. It is not meant to address other common issues such as the need for a more detailed project description or project plans, or additional information on impacts to public access and recreation, ESHA, visual resources, and so on, except insomuch as there is overlap with those issues and coastal hazards. Additionally, note that in most cases, the example language below will need to be modified, expanded, or deleted to address site or project-specific concerns. -

Plans and Prospects for Coastal Flooding in Four Communities Affected by Sandy
APRIL 2017 W O N G - P A R O D I E T A L . 183 Plans and Prospects for Coastal Flooding in Four Communities Affected by Sandy GABRIELLE WONG-PARODI Department of Engineering and Public Policy, Carnegie Mellon University, Pittsburgh, Pennsylvania BARUCH FISCHHOFF Department of Engineering and Public Policy, and Institute for Politics and Strategy, Carnegie Mellon University, Pittsburgh, Pennsylvania BEN STRAUSS Climate Central, Princeton, New Jersey (Manuscript received 4 April 2016, in final form 1 December 2016) ABSTRACT The risk of coastal flooding is increasing due to more frequent intense storm events, rising sea levels, and more people living in flood-prone areas. Although private adaptation measures can reduce damage and risk, most people living in risk-prone areas take only a fraction of those measures voluntarily. The present study examines relationships among individuals’ beliefs and actions regarding flood-related risks based on in-depth interviews and structured surveys in communities deeply affected by Superstorm Sandy. The authors find that residents recognize the risk of coastal flooding and expect it to increase, although they appear to un- derestimate by how much. Although interview participants typically cited climate change as affecting the risks that they face, survey respondents’ acceptance of climate change was unrelated to their willingness to tolerate coastal flooding risks, their beliefs about the effectiveness of community-level mitigation measures, or their willingness to take individual actions. Respondents who reported greater social support also reported both greater tolerance for flood risks and greater confidence in community adaptation measures, suggesting an important, but complex role of personal connections in collective resilience—both keeping people in place and helping them to survive there. -

Broad Beach Restoration Project Coastal Development Permit
Broad Beach Restoration Project Coastal Development Permit Project Description FINAL PREPARED FOR: TRANCAS PROPERTY OWNER’S ASSOCIATION PREPARED BY: 3780 KILROY AIRPORT WAY, SUITE 600, LONG BEACH, CA 90806 JANUARY 2011 JOB NO. 6935 1. INTRODUCTION 2 Broad Beach is located in the northwest portion of the County of Los Angeles and within the City of Malibu. The project area is comprised of the shoreline area fronting approximately 80 homes spanning approximately from Lechuza Point to Trancas Creek. Broad beach has been suffering shoreline erosion over the past 30 plus years, resulting in an almost complete loss of recreation and public access. Public access through dedicated public access ways from Broad Beach Rd. to the beach was rendered impossible during the most severe storms and tidal action over the past few years. The severe erosion problem now threatens private property and dune fields along this stretch of beach. The Trancas Property Owner’s Association (TPOA), representing almost all of the property owners along the Broad Beach shoreline, has elected to address the extensive erosion by privately funding a beach and sand dune restoration project which will not only protect their homes but also restore the beach to its historic grandeur not only for their benefit but for the benefit of the public at large. The Broad Beach restoration project seeks to design, permit, and implement a shoreline restoration program that provides erosion control, property protection, improved recreation and public access opportunities, aesthetics, and dune habitat. Broad Beach Restoration – Project Description FINAL The vicinity and location of the project site are shown below in figure 1. -
Hilo Bayfront Trails Phase I: Planning Project Area User Survey
Hilo Bayfront Trails Phase I: Planning Project Area User Survey Project Description: The County of Hawai`i has initiated a planning process for a comprehensive system of connected trails and parks along Hilo Bay. The purpose of the trails is to provide multi-use access as well as recreational and interpretive opportunities in the project area for Hilo residents and visitors. Project Area: As the name communicates, the project area comprises the bayfront of Hilo (see plan below). Stretching from the Wailuku River to Hilo Harbor, the project area embraces downtown Hilo and many public spaces, including the Wailuku riverfront, Mooheau Park, Bayfront Beach Park, Waiolama Canal, Wailoa State Park, Happiness Garden and Isles, Liliuokalani Park, Coconut Island, Reed’s Bay Beach Park, Kuhio Kalanianaole Park, and Baker’s Beach. Many roadways within the project area possess marked bicycle lanes. Use of Survey Results: The information that you provide by completing and returning this user survey will guide the project planning team, led by Helber Hastert & Fee, Planners (HHF) to produce a plan for trails and trail amenities (such as paths, rain shelters, directional and interpretive signage) that will best serve Hilo residents and visitors and that will enhance current popular uses, incorporate strongly desired future uses, and highlight cultural and historical uses of the project area. Your individual responses will be confidential. At public meetings and in the final Hilo Bayfront Trails planning report, user survey information will be communicated anonymously.

Coastal Hazards & Flood Mapping – a Visual Guide
COASTAL HAZARDS & FLOOD MAPPING A VISUAL GUIDE Coastal communities are special places and home to important resources. But what makes them so distinctive is also what makes them at high risk for floods. Floods are the nation’s costliest natural disasters, and coastal communities face many flood risks. These include storm surges, powerful waves, and erosion — all of which can cause extensive damage to homes, businesses, and public spaces. When a coastal storm approaches, community leaders and members of the media may use technical terms to describe storm-related risks. This visual guide explains these terms and how they relate to information shown on flood maps.
