On January 25, 2018 FEMA replaced this map with a new NFHL map with additional functionality which allows users to print official flood maps. On April 1, 2018 this map and NFHL link will no longer function. Please update your bookmark to https://hazards-fema.maps.arcgis.com/apps/webappviewer/index.html?id=8b0adb51996444d4879338b5529aa9cd. For more information on NFHL data availability, please visit the NFHL GIS Services page at https://hazards.fema.gov/femaportal/wps/portal/NFHLWMSAs of August 1, 2017 all FEMA systems will require the use of the “https” protocol, and “http” links will no longer function. This may impact NFHL web services. The FEMA GeoPlatform (including this map) will not be affected by this change. For more information on how NFHL GIS services will be impacted, please visit the NFHL GIS Services page at https://hazards.fema.gov/femaportal/wps/portal/NFHLWMS.An NFHL FIRMette print service is now available HERE. (For a video tutorial, click here.)OverviewThe National Flood Hazard Layer (NFHL) dataset represents the current effective flood data for the country, where maps have been modernized. It is a compilation of effective Flood Insurance Rate Map (FIRM) databases and Letters of Map Change (LOMCs). The NFHL is updated as studies go effective. For more information, visit FEMA's Map Service Center (MSC). Base Map ConsiderationsThe default base map is from a USGS service and conforms to FEMA's specification for horizontal accuracy. This base map from The National Map (TNM) consists of National Agriculture Imagery Program (NAIP) and high resolution orthoimagery (HRO) that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a map. This map should be considered the best online resource to use for official National Flood Insurance Program (NFIP) purposes when determining locations in relation to regulatory flood hazard information. If a different base map is used with the NFHL, the accuracy specification may not be met and the resulting map should be used for general reference only, and not official NFIP purposes. Users can download a simplified base map from the USGS service via: https://viewer.nationalmap.gov/services/ For the specifics of FEMA’s policy on the use of digital flood hazard data for NFIP purposes see: http://www.fema.gov/library/viewRecord.do?id=3235Letter of Map Amendment (LOMA) pointsLOMA point locations are approximate. The location of the LOMA is referenced in the legal description of the letter itself. Click the LOMA point for a link to the letter (use the arrows at the top of the popup window to bring up the LOMA info, if needed).This LOMA database may include LOMAs that are no longer effective. To be certain a particular LOMA is currently valid, please check relevant documentation at https://msc.fema.gov/ . Relevant documents can be found for a particular community by choosing to "Search All Products", and finding the community by State and County. Documents include LOMAs found in the "Effective Products" and "LOMC" folders, as well as Revalidations (those LOMAs which are still considered to be effective after a map is revised).Updates3/27/2017 - Updated all references to https to prevent issues with mixed content.5/11/2016 - Added link to NFHL FIRMette Print Service. Updated LOMA and CBRS popup notes.2/20/2014 - Created a General Reference map for use when the USGS base map service is down. Renamed this map to "Official".Further InformationSpecific questions about FEMA flood maps can be directed to FEMAMapSpecialist@riskmapcds.comFor more flood map data, tool, and viewing options, visit the FEMA NFHL page.

Stormwater Pipe/Conveyance Lines in Fuquay-Varina. Please note that many of the stormwater line features represent privately owned and maintained pipes, and these are essential for mapping and understanding the stormwater drainage network sub-systems at the neighborhood level. Please pay attention to the Subtype field to identify the different categories of public vs. private and culvert type stormwater lines. Directionality (start vs. end vertices) of these line features reflects real world flow direction. The GIS data in the area of Downtown Fuquay-Varina has a lot of old and erroneous stormwater features. A project is currently underway to correct much of this inaccurate stormwater data. Please note that ALL public utility data layers can be downloaded in a single .mpkx (ArcGIS Pro map package file), updated every Friday evening. This .mpkx file can be opened directly with ArcGIS Pro version 3+. Alternatively, you can extract the file geodatabase within it by renaming the file ending .mpkx to .zip and treating it like a zip archive file, for use in any version of ArcGIS Pro or ArcMap software. You can also use QGIS, a powerful, free, and open-source GIS software.The Town of Fuquay-Varina creates, maintains, and serves out a variety of utility information to the public, including its Potable Water System, Sanitary Sewer System, and Stormwater Collection System features. This is the same utility data displayed in our public web map. This utility data includes some features designated as 'private' that are not owned or maintained by the Town, but may be helpful for modeling and other informational purposes. Please pay particular attention to the terms of use and disclaimer associated with these data. Some data includes the use of Subtypes and Domains that may not translate well to Shapefile or GeoJSON downloads available through our Open Data site. Please beware the dangers of cartographic misrepresentation if you are unfamiliar with filtering and symbolizing data based on attributes.

This feature class represents current stormwater conduits within the City of Los Angeles. This conduit is used in conjunction with a pumping station. The Mapping and Land Records Division of the Bureau of Engineering, Department of Public Works provides the most rigorous geographic information of the storm drain system using a geometric network model, to ensure that its storm drains reflect current ground conditions. The conduits and inlets represent the storm drain infrastructure in the City of Los Angeles. Storm drain information is available on NavigateLA, a website hosted by the Bureau of Engineering, Department of Public Works.For a complete list of attribute values, please refer to (TBA Stormwater data dictionary).Stormwater conduit lines layer was created in geographical information systems (GIS) software to display the location of stormwater drainage pipes. The layer consists of spatial data as line features and attribute data for the features. The lines are entered manually based on stormwater maps, and information about the lines is entered into attributes. The Stormwater Network dataset is a geometric network, with a collection of conduit lines and inlet points having a connectivity relationship. Thus, editing the location of an conduit line affects the location of the connected inlet point, and vice versa. Conduit plans and specifications proposed under private development are reviewed and approved by City of Los Angeles, Department of Public Works, Bureau of Engineering. For more information on conduit materials and structures, look at the Bureau of Engineering Manual, Part G, Storm Drain Design, G 600 Storm Drain Structures section, and a copy can be viewed at http://eng.lacity.org/techdocs/stormdr/g600.pdf, or at http://eng.lacity.org, click Technical Info, click Technical Document Center, click Storm Drain Design Manual Part G, click G 600 Storm Drain Structures.

The stormwater pipes and culverts data is comprised of lines. The pipes and culverts are the man-made structures composed of concrete, metal and plastic used to convey stormwater from catch basins and ponds to the natural drainage ways and swales that eventually discharge to creeks and streams. The pipes and culverts data was collected primarily in eastern Loudoun in the more urbanized portions of the County and was collected in the field using GPS instrumentation. At least 95% of the locational data for the pipes and culverts is accurate to within 1 meter or less. Pipes and culverts are named and digitized in the direction of water flow.

A stormwater structure for access to the system.

The feature dataset contains storm water projects planned in the future throughout California that involve groundwater recharge and direct use. It was used to develop storm water targets for the years 2020 and 2035 per directives to DWR in California Water Code Section 10608.50 (b). As of February 2018, projects included are those proposed to be constructed post 2014. Information from various databases was used to compile the project database. More details can be found in Appendix A of the DWR report “Determination of New Statewide Stormwater Targets for Groundwater Recharge and Direct Use Benefitting Urban Water Supply”. Expected public release: March 2018.

Facilities that capture and convey stormwater and urban runoff.

The stormwater BMP data is comprised of points (dry ponds, wet ponds, underground detention, etc.). These points identify the general location of BMPs within Loudoun County, Virginia, and provide infomation about the BMP type and general maintenance. The data was collected primarily in eastern Loudoun in the more urbanized areas of the County; however, this data constantly changing. Updates to this database are generated bi-annually. For more current information contact Loudoun County Stormwater Management.
