To illustrate the coastal high hazard area for a category 1 storm surge for Palm Beach County

This data set is used as a baseline for the collection of topographic information relating to the conditions of Palm Beach County beaches. Represents the position of the Florida Department of Environmental Protection, Bureau of Beaches and Coastal Systems Range Monuments (source) along the coast. This layer was created by the Bureau of Beaches and Coastal Systems to show where monuments have been established in each of the 24 program counties. Topographic information is collected by surveying profiles at the monuments. These profiles are collected every four years as part of our Coastal Regional Monitoring Program or after a major storm event. This information provides a technical basis for construction permit review, establishment and restudy of coastal construction control lines, monitoring of shoreline changes, as well as providing a basis for assessing the need for beach restoration and other beach erosion control methods. The points are representative of the GPS location of the monuments and may not indicate an actual concrete monument. They are not to be taken as a legal description of these positions nor to be used for survey purposes. The Attribute table contains listings of the range monuments for each regulated coastal county.

WARNING: This is a pre-release dataset and its fields names and data structures are subject to change. It should be considered pre-release until the end of 2024. Expected changes:

• Metadata is missing or incomplete for some layers at this time and will be continuously improved.
  
• We expect to update this layer roughly in line with CDTFA at some point, but will increase the update cadence over time as we are able to automate the final pieces of the process.

Purpose

County and incorporated place (city) boundaries along with third party identifiers used to join in external data. Boundaries are from the authoritative source the California Department of Tax and Fee Administration (CDTFA), altered to show the counties as one polygon. This layer displays the city polygons on top of the County polygons so the area isn"t interrupted. The GEOID attribute information is added from the US Census. GEOID is based on merged State and County FIPS codes for the Counties. Abbreviations for Counties and Cities were added from Caltrans Division of Local Assistance (DLA) data. Place Type was populated with information extracted from the Census. Names and IDs from the US Board on Geographic Names (BGN), the authoritative source of place names as published in the Geographic Name Information System (GNIS), are attached as well. Finally, the coastline is used to separate coastal buffers from the land-based portions of jurisdictions. This feature layer is for public use.

• Area_SqMi: The area of the administrative unit (city or county) in square miles, calculated in EPSG 3310 California Teale Albers.
• COASTAL: Indicates if the polygon is a coastal buffer. Null for land polygons. Additional values include "ocean" and "bay".
• GlobalID: While all of the layers we provide in this dataset include a GlobalID field with unique values, we do not recommend you make any use of it. The GlobalID field exists to support offline sync, but is not persistent, so data keyed to it will be orphaned at our next update. Use one of the other persistent identifiers, such as GNIS_ID or GEOID instead.

Accuracy

CDTFA"s source data notes the following about accuracy:

City boundary changes and county boundary line adjustments filed with the Board of Equalization per Government Code 54900. This GIS layer contains the boundaries of the unincorporated county and incorporated cities within the state of California. The initial dataset was created in March of 2015 and was based on the State Board of Equalization tax rate area boundaries. As of April 1, 2024, the maintenance of this dataset is provided by the California Department of Tax and Fee Administration for the purpose of determining sales and use tax rates. The boundaries are continuously being revised to align with aerial imagery when areas of conflict are discovered between the original boundary provided by the California State Board of Equalization and the boundary made publicly available by local, state, and federal government. Some differences may occur between actual recorded boundaries and the boundaries used for sales and use tax purposes. The boundaries in this map are representations of taxing jurisdictions for the purpose of determining sales and use tax rates and should not be used to determine precise city or county boundary line locations. COUNTY = county name; CITY = city name or unincorporated

WARNING: This is a pre-release dataset and its fields names and data structures are subject to change. It should be considered pre-release until the end of March 2025. The schema changed in February 2025 - please see below. We will post a roadmap of upcoming changes, but service URLs and schema are now stable. For deployment status of new services in February 2025, see https://gis.data.ca.gov/pages/city-and-county-boundary-data-status. Additional roadmap and status links at the bottom of this metadata.

Purpose

County boundaries along with third party identifiers used to join in external data. Boundaries are from the California Department of Tax and Fee Administration (CDTFA). These boundaries are the best available statewide data source in that CDTFA receives changes in incorporation and boundary lines from the Board of Equalization, who receives them from local jurisdictions for tax purposes. Boundary accuracy is not guaranteed, and though CDTFA works to align boundaries based on historical records and local changes, errors will exist. If you require a legal assessment of boundary location, contact a licensed surveyor.

This dataset joins in multiple attributes and identifiers from the US Census Bureau and Board on Geographic Names to facilitate adding additional third party data sources. In addition, we attach attributes of our own to ease and reduce common processing needs and questions. Finally, coastal buffers are separated into separate polygons, leaving the land-based portions of jurisdictions and coastal buffers in adjacent polygons. This feature layer is for public use.

These data are benthic study GIS shapefiles (.shp, .shx, .prj) with associated .dbf attribute tables and specific Federal Geographic Data Committee metadata. A generalized browse graphic was generated at the NODC and included with these data. The data were developed to support ecosystem based management in the Humboldt Bay region. The focus of the mapping was on shallow water benthic habitats with particular concern for eelgrass meadows. The study area covers Arcata (North) Bay, Entrance Bay, South Bay and the Eel River Delta, Humboldt County, California.

This dataset displays Risk Areas which help illustrate the geographic distribution of coastal risk along the shoreline of Westchester, Nassau, Suffolk, and New York City Counties. The objective of the Risk Assessment (and resulting mapped Risk Areas) is to define areas at risk from coastal hazards. Data were collected from sources accurate enough to differentiate geographic areas according to the likelihood of flooding, erosion, waves and storm surge. To the extent allowed by source data, areas where flood water can extend up streams and under culverts and bridges are reflected in mapping. The mapping process and data sources used are described below. Mapped Risk Areas are classified into three categories: Extreme, High, and Moderate. Extreme Risk Areas: These are areas currently at risk of frequent inundation, vulnerable to erosion in the next 40 years, or likely to be inundated in the future due to sea level rise. Criteria and source data used to define these Extreme Risk Areas include: FEMA V zone. Areas subject to Shallow Coastal Flooding per NOAA NWS’s advisory threshold. Areas prone to erosion, natural protective feature areas susceptible to erosion. Added 3 feet to the MHHW shoreline and extended this elevation inland over the digital elevation model (DEM) to point of intersection with ground surface. These four criteria were overlaid and polygons were generated that included the maximum spatial extend of the above-listed criteria. These polygons represent Extreme Risk Areas. High Risk Areas: These are areas that fall outside of the Extreme Risk Areas and are currently at infrequent risk of inundation or are at risk in the future from sea level rise. Criteria and source data used to define these High Risk Areas include: Area bounded by the 1% annual flood risk zone (FEMA V and A zones). Added 3 feet to NOAA NWS coastal flooding advisory threshold and extended this elevation inland over the DEM to point of intersection with ground surface. Polygons were created that were upland of the Extreme Risk Area boundary and included the maximum spatial extent of the above-listed criteria. These polygons represent High Risk Areas. Moderate Risk Areas: These are areas that fall outside of the Extreme and High Risk Areas, but are currently at moderate risk of inundation from infrequent events or are at risk in the future from sea level rise. Criteria and source data used to define these High Risk Areas include: Area bounded by the 0.2% annual risk (500 year) flood zone, where available; Added 3 feet to the Base Flood Elevation for the current 1% annual risk flood event and extended this elevation inland over the DEM to point of intersection with ground surface; Area bounded by SLOSH category 3 hurricane inundation zone. Polygons were created that were upland of the Extreme and High Risk Area boundaries and included the maximum spatial extent of the above-listed criteria. These polygons represent Moderate Risk Areas.

In order to ensure that all development in unincorporated Palm Beach County is consistent with the Comprehensive Plan, it is necessary and proper to establish a series of districts to ensure that each use is compatible with surrounding uses, served by adequate public facilities, and sensitive to natural and coastal resources. Each district has its own purpose and has permitted uses, conditional uses, special uses and other regulations that control the use of land in each district.
