This Flood Insurance Study (FIS) may not contain all data available within the repository. It is advisable to contact the community repository for any additional data. The Federal Emergency Management Agency (FEMA) may revise or republish part or all of this FIS report at any time. In addition, FEMA may be revise part of this FIS report by the Letter of Map Revision process, which does not involve republication or redistribution of the FIS report. Therefore, users should consult with community officials and check the Community Map Repository to obtain the most current FIS report components. Selected Flood Insurance Rate Map panels for this community contain information that was previously shown separately on the corresponding Flood Boundary and Floodway Map panels (e.g., floodways and cross sections). In addition, former flood hazard zone designations have been changed as follows: Old Zone New Zone A1 through A30 AE V1 through V30 VE B X C X Initial Countywide FIS Effective Date: October 5, 2017 TABLE OF CONTENTS Page 1.0 INTRODUCTION 1 1.1 Purpose of Study 1 1.2 Authority and Acknowledgments 1 1.3 Coordination 3 2.0 AREA STUDIED 4 2.1 Scope of Study 4 2.2 Community Description 5 2.3 Principal Flood Problems 5 2.4 Flood Protection Measures 8 3.0 ENGINEERING METHODS 9 3.1 Riverine Hydrologic Analyses 10 3.2 Riverine Hydraulic Analyses 10 3.3 Coastal Analysis 10 3.4 Wave Height Analysis 11 3.5 Vertical Datum 23 4.0 FLOODPLAIN MANAGEMENT APPLICATIONS 24 4.1 Floodplain Boundaries 24 4.2 Floodways 25 5.0 INSURANCE APPLICATIONS 27 6.0 FLOOD INSURANCE RATE MAP 28 7.0 OTHER STUDIES 29 8.0 LOCATION OF DATA 33 9.0 BIBLIOGRAPHY AND REFERENCES 33 i TABLE OF CONTENTS – continued Page FIGURES Figure 1 – Transect Schematic 14 Figure 2 – Transect Location Map 17 Figure 3 – Floodway Schematic 26 TABLES Table 1 – Initial and Final CCO Meetings 4 Table 2 – Transect Data 18-23 Table 3 – Community Map History 30-32 EXHIBITS Exhibit 1 – Flood Insurance Rate Map Index Flood Insurance Rate Map ii FLOOD INSURANCE STUDY CAPE MAY COUNTY, NEW JERSEY (ALL JURISDICTIONS) 1.0 INTRODUCTION 1.1 Purpose of Study This countywide Flood Insurance Study (FIS) investigates the existence and severity of flood hazards in, or revises and updates previous FISs/Flood Insurance Rate Maps (FIRMs) for the geographic area of Cape May County, New Jersey, including the Boroughs of Avalon, Cape May Point, Stone Harbor, West Cape May, West Wildwood, Wildwood Crest, and Woodbine; the Cities of Cape May, North Wildwood, Ocean City, Sea Isle City, and Wildwood; and the Townships of Dennis, Middle, and Upper (with the exception of the Township of Lower). Please note that on the effective date of this study, the Township of Lower is not included. Therefore, please refer to the previously published FIRM and FIS for this community. This FIS aids in the administration of the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973. This FIS has developed flood risk data for various areas of the county that will be used to establish actuarial flood insurance rates. This information will also be used by Cape May County officials to update existing floodplain regulations as part of the Regular Phase of the National Flood Insurance Program (NFIP), and will also be used by local and regional planners to further promote sound land use and floodplain development. Minimum floodplain management requirements for participation in the NFIP are found in Title 44 of the Code of Federal Regulations (CFR), Section 60.3. In some States or communities, floodplain management criteria or regulations may exist that are more restrictive or comprehensive than the minimum Federal requirements. In such cases, the more restrictive criteria take precedence and the State (or other jurisdictional agency) will be able to explain them. 1.2 Authority and Acknowledgments The sources of authority for this FIS are the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973. This FIS was prepared to include all jurisdictions within Cape May County (with the exception of the Township of Lower) into a countywide format. Information on the authority and acknowledgments for each jurisdiction included in this countywide FIS, as compiled from their previously printed FIS reports, is shown below. Cape May Point, Borough of: The coastal storm surge and wave height analysis was prepared by Dewberry & Davis under agreement with the Federal Emergency Management Agency (FEMA). That work was completed in March 1994. 1 North Wildwood, City of: For the original July 1982 FIS, the coastal storm surge and wave height analysis was prepared by Century Engineering, Inc. For the February 16, 1996, revision, the analysis was prepared by the U.S. Army Corps of Engineers (USACE), Philadelphia District, for FEMA, under Inter-Agency Agreement No. EMW-92—E-3839, Project Order No. 5, Amendemnt No. A. That work was completed in February 1994. Ocean City, City of: The wave height analysis for the FIS were prepared by Dewberry & Davis for FEMA, under Contract No. EMW-C-0543. That work was completed in November 1983. Upper, Township of: The wave height analysis for the FIS was prepared by Dewberry & Davis for FEMA, under Contract No. EMW-C-0543. That work was completed in March 1983. West Cape May, Borough of: The coastal storm surge and wave height analysis for the FIS was prepared by Tippetts- Abbett-McCarthy-Stratton and the New Jersey Department of Environmental Protection (NJDEP), Division of Water Resources, Bureau of Floodplain Management, for FEMA, under Contract No. S-90022. That work was completed in December 1980. Wildwood, City of: For the July 1982 FIS, the wave height analysis was prepared by Century Engineering, Inc., for FEMA. For the February 16, 1996, revision, the analysis was prepared by the USACE, Philadelphia District, for FEMA, under Inter- Agency Agreement No. EMW-92-E-3839, Project Order No. 5, Amendment No. A. That work was completed in February 1994. 2 Wildwood Crest, Borough of: For the original July 1982 FIS, the wave height analysis was prepared by Century Engineering, Inc., for FEMA. For the February 16, 1996, revision, the analysis was prepared by the USACE, Philadelphia District, for FEMA, under Inter- Agency Agreement No. EMW-92-E-3839, Project Order No. 5, Amendment No. A. That work was completed in February 1994. The authority and acknowledgements for the FIS Wave Height Analysis for the Boroughs of Avalon and Stone Harbor and the Cities of Cape May and Sea Isle City were taken from “Phase I General Design Memorandum Cape May Inlet to Lower Township” (USACE 1980). There are no previous FISs for the Boroughs of West Wildwood and Woodbine and the Townships of Dennis and Middle. For the October 5, 2017, countywide FIS, updated coastal storm surge and wave height analysis has been performed for the entirety of the Cape May County shoreline. Flood hazard areas previously assessed by approximate methods were reanalyzed throughout the county, with results mapped using the updated topographic data provided to FEMA by the U.S. Geological Survey (USGS) and the NJDEP. This work was performed for FEMA by Risk Assessment, Mapping, and Planning Partners (RAMPP), a joint venture of Dewberry & Davis LLC, URS Group Inc., and ESP Associates. This work was completed in September 2013. Base map information for this FIRM was developed from high-resolution orthophotography provided by the New Jersey Geographic Information Network. This information was derived from digital orthophotos produced at a scale of 1:2,400 with a 1-foot pixel resolution from photography dated 2012. The projection used for the production of this FIRM is the New Jersey State Plane (FIPS 2900). The horizontal datum was North American Datum of 1983, GRS80 spheroid. Differences in the datum, spheroid, projection, or State Plane zones used in the production of FIRMs for adjacent counties may result in slight positional differences in map features at the county boundaries. These differences do not affect the accuracy of information shown on the FIRM. 1.3 Coordination Consultation Coordination Officer’s (CCO) meetings may be held for each jurisdiction in this countywide FIS. An initial CCO meeting is typically held with representatives of FEMA, the community, and the study contractor to explain the nature and purpose of an FIS, and to identify the streams to be studied by detailed methods. A final CCO meeting is typically held with representatives of FEMA, the community, and the study contractor to review the study results. 3 The dates of the initial and final CCO meetings held for jurisdictions within Cape May County are shown in Table 1, "Initial and Final CCO Meetings."

  • Climatology of Tropical Cyclones in New England and Their Impact at the Blue Hill Observatory, 1851-2012
    Climatology of Tropical Cyclones in New England and Their Impact at the Blue Hill Observatory, 1851-2012 Michael J. Iacono Blue Hill Meteorological Observatory Updated September 2013 Introduction Over the past four centuries, extreme hurricanes have occurred in New England at intervals of roughly 150 years, as evidenced by the three powerful storms of 1635, 1815, and 1938. Histories and personal accounts of these infamous hurricanes make for fascinating reading (Ludlum, 1963; Minsinger, 1988), and they serve as an important reminder of the devastating impact that tropical cyclones can have in the Northeast. Most tropical systems in New England are less damaging, but they can still disrupt our daily lives with strong winds, heavy rain, and flooding. This article, which updates an earlier report in the Blue Hill Observatory Bulletin (Iacono, 2001), will describe the climatology of all 250 tropical cyclones that have affected New England since the mid-19th century and will summarize their intensity, frequency, and specific meteorological impact at the Blue Hill Observatory. A hurricane is a self-sustaining atmospheric process in which sunlight, water, and wind combine to transfer energy from the tropics to higher latitudes. The uneven distribution of solar heating at the Earth’s surface ultimately drives much of our weather as the atmosphere continually circulates to equalize the tropical warmth and the polar cold. In the tropics, this process is normally tranquil and slow, brought about through the life cycles of individual thunderstorms, the prevailing winds, and ocean currents. However, under the right conditions very warm air and water in the tropics trigger the formation of the most efficient heat transfer mechanism available to the atmosphere: a hurricane.

  • Virginia HURRICANES by Barbara Mcnaught Watson
    Virginia HURRICANES By Barbara McNaught Watson A hurricane is a large tropical complex of thunderstorms forming spiral bands around an intense low pressure center (the eye). Sustained winds must be at least 75 mph, but may reach over 200 mph in the strongest of these storms. The strong winds drive the ocean's surface, building waves 40 feet high on the open water. As the storm moves into shallower waters, the waves lessen, but water levels rise, bulging up on the storm's front right quadrant in what is called the "storm surge." This is the deadliest part of a hurricane. The storm surge and wind driven waves can devastate a coastline and bring ocean water miles inland. Inland, the hurricane's band of thunderstorms produce torrential rains and sometimes tornadoes. A foot or more of rain may fall in less than a day causing flash floods and mudslides. The rain eventually drains into the large rivers which may still be flooding for days after the storm has passed. The storm's driving winds can topple trees, utility poles, and damage buildings. Communication and electricity is lost for days and roads are impassable due to fallen trees and debris. A tropical storm has winds of 39 to 74 mph. It may or may not develop into a hurricane, or may be a hurricane in its dissipating stage. While a tropical storm does not produce a high storm surge, its thunderstorms can still pack a dangerous and deadly punch. Agnes was only a tropical storm when it dropped torrential rains that lead to devastating floods in Pennsylvania, Maryland, and Virginia.

The natural hazard of concern identification process likely to impact a incorporated input from the County and participating jurisdictions; review of community. These are the State of New Jersey Hazard Mitigation Plan (NJ HMP) and previous hazard identified using available identification efforts; research and local, state, and federal information on the data and local knowledge. frequency, magnitude, and costs associated with the various hazards that have previously, or could feasibly, impact the region; and qualitative or anecdotal information regarding natural hazards and the perceived vulnerability of the study area’s assets to them. Table 5.2-1 documents the process of identifying the natural hazards of concern for further profiling and evaluation. For the purposes of this planning effort, the Planning Committee chose to group some natural hazards together, based on the similarity of hazard events, their typical concurrence or their impacts, consideration of how hazards have been grouped in Federal Emergency Management Agency (FEMA) guidance documents (FEMA 386-1, “Understanding Your Risks, Identifying Hazards and Estimating Losses; FEMA’s “Multi-Hazard Identification and Risk Assessment – The Cornerstone of the National Mitigation Strategy”), and consideration of hazard grouping in the NJ HMP.

  • Chapter 2.1-A Brief History of Maryland's Coastal Bays
    Maryland’s Coastal Bays: Ecosystem Health Assessment Chapter 2.1 Chapter 2.1 A Brief History of Maryland’s Coastal Bays From: Hall, M. J. Casey and D. Wells. A Brief History of Maryland’s Coastal Bays. In: Maryland’s Coastal Bays: Ecosystem Health Assessment. Updated timeline and revised narrative authored by: Catherine Wazniak Maryland Department of Natural Resources, Tidewater Ecosystem Assessment, Annapolis, MD 21401 Roman Jesien Maryland Coastal Bays Program, Berlin, MD 21801 Abstract From the early native Americans who hunted and fished the creeks and began to farm the lands, to the Europeans who settled later, to pirates and smugglers looking for hideouts among the perplexing coves and thick marshes, to most recently, the retirees and vacationers in search of more genteel escapes, Maryland’s Coastal Bays have beckoned with abundant natural scenery and resources. The human population has gradually risen and, along with natural fluctuations, has promoted change as a common theme within the Coastal Bays ecosystem. Storms come and go, battering the islands and blasting inlets for Atlantic waters, which, if not stabilized, are soon closed by sandy sediments. Stocks of fish and shellfish fluctuate, forcing the waterman and recreational angler alike to be flexible. Other natural factors also constantly change. Eelgrass thrived prior to 1930, only to be reduced by a mysterious wasting disease and then returned years later. Shorelines crumble under the unrelenting force of wind and wave, often returning as shoals far from their origin. Algal populations, microscopic cells drifting unnoticed most of the time, can swell in blooms so massive as to change the clarity and color of the water in every direction.
