It sets forth specifications for the graphic elements that are shown on the FIRMs, including the mapping format representation, presentation of base map information, map frame sizing, legend, title block and notes to user appearance, and presentation of flood hazard information. It also addresses the specifications for the FIRM Map Index, Flood Boundary and Floodway Map (FBFM) Map Index and all Preliminary and Final map deliverables. *NOTE: FEMA recognizes that not all Geographic Information Systems or Computer-Assisted Drafting and Design software support identical font styles. Therefore, the font specifications listed throughout this Appendix are to be used as a starting reference point only; any font herein that cannot be matched shall be emulated as closely as possible using True Type fonts, with consideration given to space constraints and the overall presentation of the finished product. K.1 Map Production Methods and Formats [February 2002] There are two methods of FIRM production - digital and manual. There are several distinct classifications of FIRM formats. These are Standard, Map Initiatives, Partial Map Initiatives, Countywide, Single-Jurisdiction (also referred to as “community-based”), and FIRM/Flood Insurance Study (FIS) Report Combination. Many of these methods and formats can be mixed and interchanged, as with a digital Partial Map Initiatives FIRM. K.1.1 Digital Method [February 2002] The assigned Mapping Partner shall produce digital FIRMs whenever possible for new FIRMs and for revisions of existing FIRMs. Manual (non-digital) techniques shall be employed in FIRM production only when it is more cost effective to do so and when there is not a specific request from the FEMA Regional office to convert the FIRM to digital format. K.1.2 Manual Method [February 2002] The word “manual” refers to the standard color separation techniques primarily used in the 1970s, 1980s, and early 1990s for FIRM production. Other factors may also influence the conversion of a manual cartographic FIRM to a digital FIRM such as a community’s ability and desire to use a digital product and the availability of digital base maps. It is important to note that when processing the revision of an existing FIRM manually, the assigned Mapping Partner must maintain the appearance of the existing FIRM by emulating all fonts, line weights, line styles, and screens. The specifications found in the Guidelines and Specifications for Flood Map Production Coordination Contractors, Appendix B, dated February 17, 1999, shall serve as guidance. Additionally, Mapping Partners performing manual revisions shall remove Elevation Reference Marks shown on the panels and identify the locations of benchmarks within the community. See Volume 1, Section 1.4 for a discussion of benchmark selection and Subsection K.4.1.2 for benchmark specifications. K.1.3 Standard Map Format [February 2002] “Standard” format refers to a style of presenting flood hazard information that was superceded by the Map Initiatives format beginning in the mid 1980s. Many communities’ National Flood Insurance Program (NFIP) maps date to this period and are presented in the Standard format, with floodplains and floodways shown separately on FIRM and FBFM panels. However, unless specifically directed by FEMA, all revisions shall be processed in either one or a combination of the formats described below. K.1.4 Map Initiatives Format [February 2002] The assigned Mapping Partner shall produce all FIRM creations and revisions in the Map Initiatives format whereby the information formerly shown separately on the FIRM and FBFM are combined and shown on the FIRM. The Map Repository address shall be added to the FIRM Index and in the legend of the panels that have been updated to the Map Initiatives format. If a full conversion to the Map Initiatives format cannot be justified, the Partial Map Initiatives format should be used. K.1.5 Partial Map Initiatives Format [February 2002] The assigned Mapping Partner shall use the Partial Map Initiatives format for revisions of standard format FIRMs that do not affect the majority of the FIRM panels. The Partial Map Initiatives format combines all flood hazard information to be shown on the revised FIRM panels, thereby eliminating specific FBFM panels. The Partial Map Initiatives format should only be chosen for a revision that is not large enough to justify converting the entire community FIRM to Map Initiatives or countywide format. An example of this would be a 10-panel standard format community FIRM requiring a revision of two panels. In this case, the assigned Mapping Partner would revise the two affected panels in the Map Initiatives format and eliminate the corresponding FBFM panels. When the Partial Map Initiatives option is chosen, the assigned Mapping Partner shall include special paragraphs to explain the mixed format in the FIS report. The specifics of this are detailed in Appendix J of these Guidelines. Because the Partial Map Initiatives format often requires the FBFM Index to be reprinted, this appendix includes notes to be used for FBFM Index revisions (see Subsection K.3.1). These notes explain the elimination of FBFM panels. As with Map Initiatives format, the Map Repository Address shall be added to the FIRM panels and Index. K.1.6 Countywide Map Format [February 2002] FIRMs will often be prepared in the FEMA Countywide format, whereby all jurisdictions within a given county are shown on one set of map panels. The assigned Mapping Partner shall prepare new countywide FIRMs in Map Initiatives format using digital production techniques. FEMA encourages the use of community- or county-supplied digital base maps for the production of countywide FIRMs; therefore, each base map supplied for this purpose will have its own unique specifications and appearance. The assigned Mapping Partner shall focus on the intent of the presentation and make every effort to conform to the standard base map specifications presented in Subsection K.4.1. A digital base map supplied by a community may contain unique graphic specifications, such as the portrayal of road centerlines or edge of pavement. The assigned Mapping Partner shall make changes to a digital base map only to facilitate map presentation, ease of use, or internal consistency in base map features; the assigned Mapping Partner shall coordinate these changes with the community that provided the data. Any significant deviations from the format presented in these Guidelines must be coordinated with the FEMA Lead or other designated FEMA staff. There are several additional points to consider when creating a countywide FIRM: • Countywide mapping must provide seamless coverage within the entire county area. Any mismatches in floodplains, flood hazard information, base map information, etc., that previously existed between communities must be resolved. • To ensure seamless coverage, portrayal of floodplains, Flood Profile and Floodway Data table information should be continuous for the length of the flooding sources. With that, the cross-section information must be re-lettered sequentially for the length of the detailed flooding sources. Multiple-County Communities When processing a countywide FIRM that contains a multiple-county community, the assigned Mapping Partner shall select from one of the three options listed in order of preference – show the community as an “Area Not Included” and concurrently issue a new Single-Jurisdiction format FIRM, as described in Option 1 below, or show the community on one or more FIRMs, as indicated in Options 2 or 3 below. Seamless mapping coverage between all affected jurisdictions must be obtained and overlapping coverage and/or disclaimed flood hazard information shall be avoided. Before a decision is made on the processing method which occurs during Project Scoping phase (see Volume 1, Section 1.3), the following questions must be answered: • Does the subject community prefer to keep its community-based FIRM? • In how many counties does the subject community lie? • How are the multiple-county communities shown on the FIRMs of surrounding counties? • What is the status of the surrounding counties relative to countywide processing? • Does the subject community have full jurisdiction over its lands? • How much of the subject community falls within the county that is being processed? • What is the map scale of the existing community-based FIRM? • How many panels would be added to the countywide FIRM in order to include the subject community in its entirety? Once the questions above have been answered and all information has been obtained, the final decision regarding processing shall be made in consultation with the FEMA Project Officer. The three options discussed below ensure seamless mapping coverage for all jurisdictions, and prevent overlapping and/or duplicated flood hazard information from being shown on two separate FIRMs. Processing Option 1 Under this option, the FIRMs of the surrounding counties would show the community as an “Area Not Included” (no flood hazard or base map information shown), and the community would retain its Single-Jurisdiction format FIRM. If orthophoto base maps are used for the countywide FIRMs, the base map imagery will continue through the Area Not Included. When this option is chosen during the processing of a Countywide format FIRM, a concurrent community-based FIRM revision must be processed, if required, to ensure that seamless coverage between the multiple-county community and the surrounding counties will be maintained. Minor revisions of the FIRMs for adjacent counties may be necessary to ensure that no overlaps or gaps in coverage exist. Only NFIP communities (i.e., those (that have been assigned a Community Identification Number [CID]) may be shown as an Area Not Included. All other land-use areas such as national parks, military reservations, etc. shall be shown and labeled on the FIRM. Processing Option 2 Under this option, the entire community is mapped on the new countywide FIRM. This option shall be used when the following criteria are met: • The multiple-county community can be shown on the new countywide FIRM without substantially increasing the panel count; and • At least 70% of the community area is located within the countywide FIRM being processed. When Option 2 is chosen, the assigned Mapping Partner shall notify the FEMA Map Service Center (MSC) to supersede the community-based FIRM for the multiple-county community. The MSC must also be notified to include a notation in the Flood Map Status Information System that the subject multiple-county community is shown in its entirety on the new countywide FIRM. The adjacent counties will continue to show the subject multiple-county community as an Area Not Included on their FIRMs, even if their FIRMs are converted to the countywide format at a future date. This decision will be made on a case-by-case basis with the FEMA Project Officer. Processing Option 3 Under this option, flood hazards in the multiple-county community are shown on the countywide FIRMs of the respective counties. This option shall be used only when the following criteria are met: • All adjacent counties in which the multiple-county community is located either already have countywide FIRMs or will have in the near future; and • The multiple-county community has been consulted and has not expressed significant concerns with being shown on more than one FIRM. When Option 3 is chosen, if the processing of any of the contiguous countywide FIRMs that share the subject community are delayed (usually as a result of an appeal, protest, or other study complication), thereby making it impossible for all countywide FIRMs to become effective at the same time, the multiple-county community shall retain the community-based FIRM (see Option 1 above). In this situation, the assigned Mapping Partner must consult the FEMA Project Officer for a decision on how to proceed. Decisions will be made on a case-by-case basis, but must result in continuing and non-conflicting coverage for all land areas being mapped. Once all issues causing the delay are resolved, the assigned Mapping Partner can then proceed with the inclusion of the community into each countywide FIRM. When Option 3 is chosen, the assigned Mapping Partner must notify the MSC to supersede the community-based FIRM for the multiple-county community. K.1.7 Single-Jurisdiction Format [February 2002] In the Single-Jurisdiction format, all areas within a single community’s jurisdiction are shown on one FIRM. The assigned Mapping Partner shall prepare single-jurisdiction FIRMs when funding constraints or lack of suitable base map data prohibit full countywide mapping. Many FIRM updates affect only a portion of a community (i.e., only a few map panels instead of the entire community). When this is the case, a decision must be made whether to convert an entire manual FIRM to a digital FIRM during the revision or whether to process revisions manually. The decision shall be made with the following in mind: • FEMA’s goal is to convert its entire inventory of manual maps to a digital format. • One of the primary benefits of digital mapping is that it will reduce the cost of future revisions. • Many of the steps required to convert a study to a digital product require nearly as much time for a partial digital study as for a full digital study, thus reducing costs in the long run. Digital conversion of only the revised panels (partial digital conversion) is not the preferred option, but may be undertaken when funding constraints prohibit full digital conversion. K.1.8 FIRM/Flood Insurance Study (FIS) Report Combination Format [February 2002] For small communities that are shown on single-jurisdiction FIRMs, a combination FIRM and FIS report may be created. This involves printing one FIRM panel as defined under the Map Initiatives format described above containing all identified floodplains for the community as well as a condensed version of the FIS report. The use of this format should eliminate the requirement to create and print a separate FIS report. Space limitations will guide the decision on using this map format. At a minimum, the assigned Mapping Partner shall include the Flood Profiles, and Floodway Data and Summary of Flood Discharges tables on the FIRM. The assigned Mapping Partner shall also modify the FIRM Notes to Users to reference the map instead of the FIS report as the source of certain pertinent information. Examples of the notes and how they are modified are shown in Subsection K.7.1. The decision to create a combination FIRM and FIS report shall be made in consultation with a FEMA Project Officer. K.2 Map Frames [February 2002] Mapping Partners shall select frame sizes for Map Indexes and FIRM panels depending on whether the FIRM is being produced digitally or manually and whether the Index may be produced on 8 ½” x 11” paper. Specifications for map frame features and notes are presented Table K-1. Table K-1. Map Frame Features and Notes *Font specifications that cannot be matched may be approximated Example Feature/Usage Specification JOINS PANEL [panel number] Panel Neatline and Joins Panel Note: This note is used along each neatline of the map panel to indicate the number of the adjacent panel. The panel number includes only the 4- digit panel number and not the community number or the 5-digit FIPS code used for countywide FIRMs. In cases where more than one panel joins the subject panel (as is the case where a smaller scale panel abuts two larger scale panels), more than one “Joins Panel” note is shown along a single neatline.

Figure K-2 K.2.3 8½” x 11” Frames [February 2002] Map Indexes for small communities with few map panels may be printed on 8½” x 11” paper. The dimensions of this map frame are shown below: • Trimmed paper size: Height 8 ½ ” x Width 11” • Map border size: Height 7.5” x Width 10.0” • Title Block box: • Overall dimensions: Height 6.00” x Width 3.30” • Striped side box: Height 5.60” x Width 0.78” • Title box: Height 5.60” x Width 2.50” • Striped upper box: Height 0.385” x Width 0.78” • Upper box: Height 0.385” x Width 2.50” Subsection K.3.4, Figure K-15, provides an example of an 8½” x 11” Map Index. K.3 Map Index [February 2002] The assigned Mapping Partner shall produce a Map Index for every community that requires more than one printed map panel. Map Indexes may be prepared in an 8½” × 11” format for small- to medium-sized communities. When the panel count becomes large enough to render an 8½” × 11” Index unusable or illegible, a Z-fold Index is required. Z-fold Indexes must always be prepared for countywide FIRMs. Countywide FIRMs may require more than one Map Index sheet. A Map Index may be revised to include changes in community boundaries; the addition of map panels to the grid layout; the addition of roads, drainage lines, and other physical features; and revisions of dates and notes. When such revisions are necessary, the assigned Mapping Partner shall make these changes in a format consistent with that of the existing Map Index and according to the standards applied in the preparation of that Index. When a new Map Index layout is necessary for a single-panel FIRM that must be expanded to a multiple-panel FIRM, or when an existing layout must be completely revised, the assigned Mapping Partner shall prepare a new FIRM Map Index. K.3.1 Map Index Body Elements and Specifications [April 2003] The entire jurisdictional area of the community, including corporate and Extraterritorial Jurisdictional (ETJ) limits, if appropriate, shall be divided into map panels, following standard grid layout procedures (see Volume I, Section 1.4 of these Guidelines). The Map Index shall have the same directional orientation as the individual map panels; for all digital FIRMs, north shall be oriented to the top of the page. Panel neatlines shall be accurately placed with respect to the community layout. The locations and names of major flooding sources, major roads, corporate limits, and selected railroads shall be shown to facilitate the orientation and location of the individual panels. These features are a subset of the vector data in the digital FIRM files. For orthophoto base map data, vectors for the major reference features shown on the Index may be derived from public domain sources, such as 1:24,000 scale U.S. Geological Survey (USGS) Digital Line Graphs (DLGs). Areas within the corporate limits that were not studied shall be labeled as such whenever the scale of the Map Index permits. K.3.1.1 Community-Panel Numbers and Map Numbers [February 2002] Each panel shown on the Map Index must contain a map number. The map number may be comprised of the Community Identification Number (CID), four-digit panel number, and the suffix, or the countywide FIPS code, the letter “C”, the four-digit panel number, and the suffix. The Map Index shall identify unprinted panels with asterisks and footnotes that define the reason(s) for the panel not being printed. The appropriate reason(s) for the panel not being printed shall appear as a footnote(s) below the lower left-hand corner of the grid layout. A listing of appropriate footnotes is provided in Table K-2 in Subsection K.3.1.3. Suffix changes shall be reflected both on the FIRM panel and the Map Index. The suffixes for unprinted panels should not change unless all panels are revised. K.3.1.2 Map Dates [February 2002] The FIRM Map Index shall show the FIRM effective date in the title block. This date shall be designated in the title block as “Effective Date” (on the first FIRM for the subject jurisdiction or first countywide) or “Map Revised” (on FIRMs that have been revised at least once). When the preliminary copy of the Map Index is prepared, this date should be left blank. When the final copy of the Map Index is prepared, the date determined for the FIRM shall be added. Sample Map Index title blocks are shown in Subsection K.3.3. Similar type styles and sizes are acceptable, and may vary due to Map Index size limitations. Map Indexes shall also list the effective date of each FIRM panel below the panel number on the Map Index to assist the user in determining current panel dates, as shown in Figure K-3. 17097C0159B 06/20/97 17097C0159B 06/20/97 17097C0159A 09/04/94 17097C0159A 09/04/94 Figure K-3. Panel Effective Dates on Map Index When adding map dates under the panel numbers becomes problematic due to high levels of base map detail on the body of the Map Index, a second option is to list the dates of all printed panels in a separate FIRM Panel Dates table on the Map Index. When multiple Map Index panels exist, this table will list FIRM panels on a Map Index panel-specific basis. Figure K-4 shows a sample table with suggested font specifications. 10 Pt.

Arial CAPS MAP DATES This FIRM Index displays the map date for each FIRM panel at the time that this Index was printed. Because this Index may not be distributed to unaffected communities in subsequent revisions, users may determine the current map date for each FIRM panel by visiting the FEMA Map Service Center website at http://msc.fema.gov or by calling the Map Service Center at 1-800-358-9616. Communities annexing land on adjacent FIRM panels must obtain a current copy of the adjacent panel as well as the current FIRM Index. These may be ordered directly from the Map Service Center at the number listed above. An inventory of NFIP panels is available through the Map Service Center website. Therefore, this note shall be placed on all countywide format FIRM Indexes above the FIRM Panel Dates table (if this option is chosen) or in a clear area of the FIRM Index (if the dates are shown within the individual map grids). If more than one FIRM Index is required to show the jurisdiction, this note is placed on each FIRM Index panel. (Header) 10 Pt. Arial Bold CAPS with underscore (Reference note) 9 Pt. Arial CLC K.3.1.5 Flood Boundary and Floodway Map Index [February 2002] FBFM Indexes shall be revised whenever the FIRM is prepared in the Partial Map Initiatives format. The Partial Map Initiatives format may be used for restudy or revision map action when it is determined that total conversion to Map Initiatives is not cost effective. When the Partial Map Initiatives format is used, the FBFM panel(s) is superseded by the FIRM panel and the FBFM Index reflects this change. The appropriate “Panel Not Printed” footnote should be added to the Index for FBFM panels that are superseded by Partial Map Initiatives FIRM panels. See Table K-4 for the proper wording of the “Panel Not Printed” footnote. In addition to the Panel Not Printed footnote, a note shall be added to the body of the FBFM Index informing the user that the former FBFM panels have been superseded by the FIRM panels. See Table K-4 for the proper wording of the note. When preparing a revised FBFM Map Index, map dates shall appear beneath each FBFM panel number within the map grid. The assigned Mapping Partner shall ensure that the remaining separately printed FBFM panels have the correct date under the panel number. Dates that appear on non-printed panels shall be removed. The assigned Mapping Partner shall notify the MSC by memorandum or e-mail when Map Initiatives FIRM panels supersede FBFM panels. Table K-4.

These elements include a Listing of Communities table, a list of the Map Repositories, and multiple index sheets where applicable. K.3.2.1 Listing of Communities Table and Note to User [April 2003] The assigned Mapping Partner shall ensure that the countywide Map Index contains a Listing of Communities table that lists, in alphabetical order and in tabular form, all jurisdictions included in the FIS. The table shall also list non-floodprone communities in the county, footnoted as “Non-floodprone” indicating their non-floodprone status. The listing shall not include communities that are labeled as Areas Not Included. Each community shall have its CID listed on the table in the “Community Number” column. Each panel showing any portion of a community, including non-printed panels shall be listed next to the community in the “Located on Panel(s)” column. Non-printed panels shall be footnoted as “Panel Not Printed.” Historical map dates shall be listed in the “Initial NFIP Map Date,” “Initial FIRM Date” and “Most Recent FIRM Panel Date” columns. The Initial NFIP Map Date is the date of the community’s first flood hazard map, which may be a Flood Hazard Boundary Map (FHBM), a combined FHBM/FIRM, or a FIRM. If the Initial NFIP Map Date does not correspond to the Initial Identification Date in the legend of the most recent map panel, a footnote shall be placed beneath the table to state the Initial Identification Date. The Initial FIRM Date is the date of the community’s first FIRM. The Most Recent FIRM Panel Date column shall list the last date on which a panel showing that community was published. This date will identify the communities affected by the republication of the Map Index, since the Map Index is updated every time a panel within the county is republished. If a portion of the countywide panels are being revised for the first time since the countywide’s initial publication and the “Most Recent FIRM Panel Date” column does not appear in the Listing of Communities table on the Map Index, the column shall be added along with the following footnote: *Includes Most Recent Map Index Every community in the Listing of Communities table will receive the revision Map Index but only those communities which appear on revised map panels will received the map panels. Therefore, the footnote shall be added to indicate that the Map Index may be the only panel with the revised map date for some of the communities in the listing. When the entire set of countywide panels is revised in the same revision, this note would no longer apply and thus be removed. An example of a revised countywide’s Listing of Communities table is shown in Figure K-5. The note shown in Table K-6 shall be added above the north arrow of a countywide Map Index to clarify the meaning of the dates in the Listing of Communities table. Table K-6. Listing of Communities Table Note *Font specifications that cannot be matched may be approximated Example Usage Specification* NOTE TO USER Future revisions to this FIRM Index will only be issued to communities that are located on FIRM panels being revised. This FIRM Index therefore remains valid for FIRM panels dated [date] or earlier. Please refer to the "MOST RECENT FIRM PANEL DATE" column in the Listing of Communities table to determine the most recent FIRM index date for each community. This note is added to all countywide Map Indexes to inform map users that the Map Index may be republished in the future but not distributed to them unless they are affected by the revision.

Arial CLC K.3.2.3 Multiple Map Index Panels [February 2002] FIRMs that are presented on one Map Index panel have the Map Number “IND0.” It may sometimes be necessary to create multiple Map Index sheets to present large countywide FIRMs. In such cases, the Listing of Communities table and Map Repositories list shall appear separately on a second Map Index sheet. Sometimes, it may also be necessary to split the image of the community itself onto multiple Map Index sheets. In such cases, a match line shall be added and labeled with a note that references the adjoining Map Index sheet. In addition, the Map Numbers of those sheets shall be “IND1,” “IND2,” etc., and an Index Locator Diagram shall be added to each Map Index sheet, proportionate in size to other elements. Examples of an Index Locator Diagram are shown in Figures K-6 and K-7. Also, see Figures K-9 and K-10 for examples of multiple-sheet Map Index title blocks. figure K-6 figure K-7K.3.3 Index Title Block [April 2003] The Index title block must be similar in appearance to the FIRM title block, with the exception that it must contain a listing of all of the printed panels instead of community-specific information. The following pages contain examples of the following Map Index title blocks: • Countywide Digital FIRM Index Title Block (Figure K-8); • Countywide Multiple-sheet Digital FIRM Index Title Block, Sheet 1 of 2 (Figure K-9); • Countywide Multiple-sheet Digital FIRM Index Title Block, Sheet 2 of 2 (Figure K-10); • Single-Jurisdiction Digital FIRM Index Title Block (Figure K-11); • Single-Jurisdiction Manual FIRM Index Title Block (Figure K-12); and • Single-Jurisdiction Manual FBFM Index Title Block (Figure K-13).

Arial Bold CLC *PANEL NOT PRINTED – NO SPECIAL FLOOD HAZARD AREAS “Panel Not Printed” Notes 7-8 Pt. Arial CAPS K.4 Map Body [February 2002] The body of the FIRM shall be comprised of base map information and flood hazard information, including any special notes needed for clarification, and, in applicable communities, areas designated as Coastal Barrier Resources System (CBRS) units where federal flood insurance is unavailable. K.4.1 Base Map [February 2002] Base maps form the backdrop against which flood hazard information is viewed. Digital base maps also provide horizontal control for effective information compiled from existing FIRMs, FBFMs and FHBMs. Base maps cover the entire geographical area of a community and include planimetric data such as transportation features, hydrographic features, hydraulic structures, landforms, and political boundaries. The printed FIRM shall not depict topographic (elevation) data such as contour lines. Base map features are employed by map users to locate properties and structures relative to the floodplains; therefore, the accuracy of the base maps used in the production of FIRMs is important to the overall precision of the FIRMs. Base map data supplied by the community are preferred for use in FIRM production. Once a base map has been accepted, the locations of features in the base map data files are used as-is. To facilitate fitting data together from multiple sources, base map features from one source may be clipped where they meet those from another source. Small graphical mismatches between communities where roads or other features cross community boundaries must then be resolved. This processing should allow for the creation of seamless digital data files. For additional details regarding base map specifications, refer to Volume I, Subsection 1.3.4.1. K.4.1.1 Base Map Types [February 2002] This subsection contains guidance for the presentation of raster images and vector data used as FIRM base map information. Raster Images Raster maps can be produced from digital data or they can result from the digital scanning of paper maps, map negatives, and aerial photographs, and/or from the orthorectification of those images so that they are accurately georeferenced with any distortions removed. Georeferencing means that the map depicts the spherical earth projected as a plane map, normally with Universal Transverse Mercator (UTM) or State Plane coordinates, with or without tick marks or lines that depict parallels (lines of equal latitude) or meridians (lines of equal longitude). Human interpretation of scanned or imaged features is required to derive intelligence from raster maps. The most common form of raster image map is the digital orthophoto, especially the standard Digital Orthophoto Quadrangle (DOQ) produced by the U.S. Geological Survey (USGS). Whenever possible, the assigned Mapping Partner shall use orthophoto images as they are received from the USGS or the community. The image shall cover the entire FIRM panel, even if some of the image falls outside the jurisdiction being studied. The assigned Mapping Partner shall not crop the image at the jurisdiction’s boundary. However, no imagery shall be shown outside the FIRM panel neatline. On FIRM panels that are only partially covered by the studied jurisdiction, a note shall be added in areas outside the jurisdiction to clarify that flood hazards may exist outside the jurisdictional boundary. An example of the note is shown in Subsection K.4.3. Variations in tones between orthophoto images are acceptable. If more than one image is included on a FIRM panel, lightening or darkening of individual images to balance tones is not necessary. Overall lightening of all orthophoto images for a Flood Map Project using a single factor may be done so that flood hazard features can be clearly seen. The assigned Mapping Partner may update roads or other features that have changed since the orthophotos were produced, placing vector data on top of the images if available. A note shall be added to the map to clarify significant additions as necessary. The assigned Mapping Partner may show vectors that depict studied flooding sources on top of the orthophotos to clarify their locations. Vectors shall not be shown outside the Special Flood Hazard Areas (SFHAs) unless removing them would entail additional work. Vector Data [February 2002] Vector base maps depict linear features (e.g., roads, railroads, streams) digitized as single-line centerlines or, alternatively, as dual lines showing the outer extremities of linear features (e.g., left and right banks of streams, curb lines on both sides of streets). Roadway right-of-ways or buffered road centerlines are not desirable because they do not depict a feature that can be physically located by users, who rely on the base map features for general orientation. Users often measure distances from road features in order to locate structures for insurance rating purposes. Road centerlines or edges of pavement are more suitable for this type of use. K.4.1.2 Base Map Features [April 2003] The following are the types of base map features that the assigned Mapping Partner shall depict on the FIRM if they occur within the community: • Transportation features, including roads, railroads, and airports shall be depicted. If digital orthophotos are supplied, these features must be clearly visible. Bridges that are included in the hydraulic models shall be included on the FIRM. Unimproved roads or trails (i.e., those travel ways not intended for motorized vehicles or not usually used by motorized vehicles due to width or seasonal conditions) may be included, particularly if they cross the floodplains. • Hydrographic features (e.g., streams, rivers, lakes, shorelines) shall be depicted. • Hydraulic structures (e.g., levees, dams, weirs, floodwalls, jetties) shall be depicted. • NGS bench marks shall be depicted. • Political and other boundaries that identify county and state boundaries, corporate limits, extraterritorial jurisdictional areas, military lands, Native American lands, parks, forests, state gamelands, wildlife refuges, and similar areas shall be depicted. • U.S. Public Land Survey System (PLSS) features, also known as range, township, and section lines, and their designators, shall be depicted. Graphic and usage specifications for other horizontal reference grid systems are also included here. • Significant land forms shall be depicted. • Other features and notes shall be depicted. • All features listed above shall include names and/or labels. The assigned Mapping Partner shall separately symbolize base map features that are not clearly visible on the orthophoto due to their location within a floodplain. For example, a dam symbol should be outlined if it is not visible on the orthophoto or if other floodplain features obscure it. The assigned Mapping Partner shall derive base map feature names from community-supplied files or hardcopy sources, current FIRM panels, U.S. Census Bureau Topologically Integrated Geographic Encoding and Reference System files, and/or other sources. All feature names that are available in digital format shall be shown on the FIRM. All feature labels on orthophotobased FIRMs shall be shown as black text with a white halo around the letters to enable the names to be clearly read against the intensity of the background image. Feature labels on vector- based FIRMs shall be shown as black text. Further graphic specifications are provided in the tables below, with separate paragraphs emphasizing information of particular importance. Please note that the tables throughout this section contain specifications for orthophoto and vector base maps. In general, the vector-based examples also apply to FIRMs that are produced manually. Specific exceptions are individually noted. In general, bold type fonts surrounded by a white halo are used on orthophoto-based FIRMs. Medium type fonts are used on vector-based FIRMs where the background allows them to show more clearly. All base map features and labels are shown on the FIRM in black unless otherwise noted. Transportation Features All primary roads, all roads located inside or within one inch of an SFHA, and any road shown and labeled on a Flood Profile shall be labeled on the map. When space permits, secondary and tertiary roads farther than one inch from an SFHA shall be labeled. If a community supplies digital road labels beyond the stated minimums, these labels shall be shown on the FIRM, provided they meet the text placement standards and do not render the map unusable due to excessive clutter. Road name labels shall be placed parallel to the road and spaced so that there is no more than one-half inch between each word in the road name. Additional road name labels shall be added for roads that traverse entire FIRM panels, or as necessary for clarity. All railroads that traverse the community’s mapped area shall be labeled. When available, the formal name taken from the sources defined above is to be used. The name shall be placed along the feature when feasible or leadered, if space is limited. If several different names for the same feature are available and would cause clutter and/or confusion, the generic term “Railroad” shall be used. If the generic name option is used, the formal name shown on the unrevised flood profiles shall not be changed.

The marks shall be identified by their NSRS Permanent Identifier (PID). When local jurisdictions have established their own vertical control monument network, these monuments may also be shown on the FIRM with the appropriate designations. The assigned Mapping Partner shall show local vertical control monuments on the FIRM only if the community has requested that they be included, the monuments meet the aforementioned inclusion criteria, and the community maintains the monuments and provides public access to information about the monuments such as their location, description, and elevation. Specifications for the depiction of bench marks and local vertical control monuments on base maps are presented in Table K-12. Refer to Volume 1, Subsection 1.4.2.1 of these Guidelines for additional information on the criteria for showing bench marks on FIRMs. Table K-12.

If the label does not fit inside the area, the label should be placed nearby and leadered into the area. The area boundary shall also be labeled in accordance with the guidance below. Where boundary labels are appropriate but there is not enough space along the boundary, the boundary label may be omitted; however, the area itself must always be labeled. Political entities (incorporated areas, unincorporated areas, Extraterritorial Jurisdictions, Areas Not Included, etc.) shall be labeled with the appropriate jurisdiction names and CIDs or area designator, placed near the center of the jurisdiction, if possible. For incorporated communities, the community type shall be followed by the name of the community (e.g., City of Smithville), and the CID placed immediately under the community name. For unincorporated county areas, the county name should be shown with “Unincorporated Areas” beneath it and the county CID should be placed immediately under that label. On single-jurisdiction FIRMs, the appropriate entity name shall be placed on each side of the corporate limits boundary. The label for the adjoining community should be determined by the hierarchy of the area being identified. The following are examples of adjoining communities: • “City of Fairfield” (the adjoining incorporated community is within the same county as the mapped jurisdiction). • “Crenshaw County” (the adjoining county is within the same state as the mapped jurisdiction). • “City of Fairfield” and “Wisconsin” (the adjoining community is within a different state than the mapped jurisdiction). • “Washington County” and “Wisconsin” (the adjoining county is within a different state than the mapped jurisdiction). For the second and third example, the community boundary is also a state boundary; therefore the state name shall be shown in conjunction with the outside area’s community name. On countywide FIRMs, corporate limits boundaries shall be labeled with the appropriate jurisdiction name on each side of the boundary. If a multiple-county community is shown in its entirety on a countywide FIRM, the county boundary that divides the community shall be labeled with the county names on each side. If the boundary is also a state boundary, the state names shall be shown as well. When Extraterritorial Jurisdictional (ETJ) areas are significant for the purposes of the NFIP, they shall be shown on the FIRM. The ETJ area shall be labeled with the community name, followed by the words “Extraterritorial Jurisdiction,” and the CID number of the community exercising its extraterritorial jurisdiction authority. ETJ boundaries shall be labeled on the ETJ side of the boundary with “[Community Name] Extraterritorial Jurisdiction Limits.” If there are space constraints, the label may be shortened to “[Community Name] ETJ Limits.” Any area shown as an “Area Not Included” shall be labeled with the appropriate jurisdiction name and “Area Not Included” centered within the area. Flood hazard information shall not be depicted in these areas. In addition, orthophoto-based FIRMs shall not show labels for planimetric features; vector-based FIRMs shall not show base map information of any kind in an Area Not Included. An exception occurs when a flooding source studied in detail passes through the area, in which case the stream centerline or shoreline shall be shown. The Area Not Included boundary shall not be labeled. For additional information on depicting Areas Not Included, see Subsection K.1.6. All other areas, such as military lands, Native American lands, parks, forests, state gamelands, and wildlife refuges shall be labeled with the official name at least once. If the area is large, additional labels should be added as needed. The boundary of a park, forest, or state gameland should be labeled “PARK BOUNDARY” (or whatever the land use area boundary represents) along the outside, parallel to the boundary. When boundaries of different types are coincident with each other or with base map features, the Mapping Partner shall show only one, with preference given as follows (presented from highest to lowest priority): 1. Political boundary 2. Coastal Barrier boundary 3. Flood insurance risk zone boundary 4. Other boundaries 5. Base map feature In general, the heaviest or widest line is most prominent. For example, if a corporate boundary, a road, and a flood hazard zone boundary are coincident, only the corporate boundary is to be shown. Jurisdiction and park boundary specifications are provided in Table K-13. Table K-13.

Times New Roman CAPS or CLC Horizontal Reference Grids The assigned Mapping Partner shall ensure that the FIRM contains a primary horizontal reference grid and secondary horizontal reference grid ticks to orient map readers to real-world coordinates; the latitude and longitude in degrees, minutes, and seconds shall be referenced at each of the four corners of the map panel; and the Universal Transverse Mercator (UTM) reference grid (or grid ticks) are included on the FIRM. Other reference grids (e.g., State Plane) may also be included. UTM, State Plane, and latitude/longitude reference grids or grid ticks shall be shown on the FIRM extending to the FIRM neatline. U.S. Public Land Survey System (PLSS) features (i.e. range, township, and section lines) shall be shown on a digital FIRM if they are available in digital format and/or were shown on a previous FIRM. The assigned Mapping Partner shall avoid mix-and-match situations where only some FIRM panels in a given jurisdiction contain section information. If the selected base map for a countywide FIRM does not include PLSS information, but some of the community-based FIRMs within the county showed this information previously, a concerted effort shall be made to ensure that the PLSS information is obtained and shown on the entire FIRM. The PLSS information shall meet the following specifications: • Section numbers shall be placed in the center of the section (or portion of the section shown on the panel) parallel to the horizontal neatlines of the panel. • Township lines shall be labeled at the left and right edges of the panel along both sides of the line. • Range lines shall be labeled at the top and bottom edges of the panel along both sides of the line. • Range, township, and section lines shall be terminated at the panel neatline and at the political boundaries of the subject community. If the community being studied uses a PLSS grid, the primary grid shown on the FIRM shall be the PLSS. Otherwise, the primary horizontal reference grid shall be the same as the coordinate system of the digital data. For example, if the digital files are referenced to the UTM coordinate system, a UTM grid shall be shown on the map. If the digital files are referenced to the State Plane coordinate system, a State Plane grid of Northings and Eastings shall be shown on the map. If the community being studied uses a PLSS grid, the secondary grid ticks shall be the same as the coordinate system of the digital data. When digital files are referenced to the UTM coordinate system, UTM grid ticks shall be shown as cross hairs within the body of the map and ticks along the edge. State Plane grid ticks are not required but may also be shown along the edges of the panel. When the digital files are referenced to the State Plane coordinate system, both UTM and State Plane grid ticks shall be required. If the community does not use a PLSS grid, the secondary grid ticks shall be shown as cross hairs within the body of the map and ticks along the edge. When the primary grid is UTM, the secondary grid ticks shall be State Plane. When the primary grid is State Plane, the secondary grid ticks shall be UTM. The grid interval shown on the FIRM shall not vary between panels within the same FIRM even if the panels are shown at different scales. Generally, a UTM grid interval of 1,000 meters and a State Plane grid interval of 5,000 feet shall be used. Specifications for reference grids are listed in Table K-14. Table K-14 Other Base Map Features and Notes The features and notes in Table K-15 shall be added to the FIRM as needed. Table K-15.

K.4.2.1 Floodplains and Floodways [February 2002] The 1-percent-annual-chance (100-year) and 0.2-percent-annual-chance (500-year) floodplain boundaries must be shown on the FIRM. The boundaries of Zone D areas must be shown unless they abut the 1-percent-annual-chance floodplain, in which case the 1-percent-annual-chance floodplain boundary shall take precedence. Regulatory floodways shall be shown on the FIRM and, at cross-section locations, must agree with the values shown on the Floodway Data table in the FIS report within a maximum tolerance of five percent of the map scale or five percent of the distance, whichever is greater. When the 1-percent-annual-chance and regulatory floodway boundaries converge such that they become coincident, only the floodway boundary shall be shown. The use of GIS and automated mapping techniques for the delineation of floodplain and floodway boundaries allows very small areas of flooding to be shown in the digital files. Mapping Partners must exercise some judgment in selecting which of these areas to show on the FIRM. Extremely small areas may be eliminated in some cases. However, in general, all 0.2- percent-annual-chance floodplain areas that are adjacent to 1-percent-annual-chance floodplain areas, no matter how thin, must be retained in the digital files. K.4.2.2 Flood Hazard Information Based on Future-Conditions Analyses [February 2002] At the request of a community and with the approval of FEMA, FIRMs may include, for informational purposes, flood hazard areas based on projected- or future-conditions hydrologic and hydraulic analyses. If community officials request that FEMA show the future-conditions 1- percent-annual-chance floodplains on the FIRM, the future-conditions floodplains and flood insurance risk zone shall be shown on the FIRM and referenced in the accompanying FIS report. Although graphic specifications are flexible for the mapping of this flood insurance risk zone, the zone label will be “Zone X (Future Base Flood).” The future-conditions flood insurance risk zone shall be defined in the FIRM legend as follows: Zone X (Future Base Flood) is the flood insurance risk zone that corresponds to the 1-percent-annual-chance floodplains that are determined based on future- conditions hydrology. No BFEs or base flood depths are shown within this zone. FEMA opted to use the Zone X (shaded) screen, in lieu of a new flood hazard zone designation, to depict the future-conditions 1-percent-annual-chance (100-year) floodplain to minimize confusion by users of the FIRM that make determinations regarding Federal mandatory flood insurance purchase requirements. Those users now recognize that areas designated as Zone X (shaded) are floodprone, but that the mandatory flood insurance purchase requirement does not apply. Because the risk premium rates for buildings located in the future-conditions 1-percent- annual-chance (100-year) floodplain will be the rate comparable to other areas outside the SFHA, FEMA believes designating these areas as “Zone X (Future Base Flood)” will be sufficient distinction. K.4.2.3 Zone Labels [February 2002] All zone areas shall be labeled at least once with their appropriate flood zone and static elevation or depth, if appropriate. Zone labels should be repeated as necessary for clarity in large or complicated areas. Very thin areas of 0.2-percent-annual-chance floodplain that border 1-percent-annual-chance floodplain areas shall be labeled where the areas become wide enough to be seen at the printed map scale. In the 1-percent-annual-chance floodplains, the floodway fringe areas should not be considered separate areas requiring labels. One zone label should be sufficient for both the regulatory floodway and the floodway fringe. When it is necessary to leader a label to isolated Zone X areas (shaded and unshaded) or clusters of Zone A areas, one label with two or more leaders may be used. K.4.2.4 Base Flood Elevations [February 2002] BFEs of increasing elevation values shall be shown in floodplains as wavy lines perpendicular to the flow of the 1-percent-annual-chance flood. All BFEs should be labeled with an elevation value that is located above, below, or at the end of the line (i.e., where it meets the 1-percent- annual-chance floodplain boundary). If the BFE value cannot be placed within 0.1 inch of the BFE line, a leader line should be used to connect the BFE value to the BFE line. BFEs in floodplains with uniform elevations shall be shown as static (single) values. The value shall be placed below the zone label. The basic intent of plotting BFEs on a FIRM is to represent the Flood Profile to within 0.5 foot of elevation tolerance. If BFEs are plotted correctly, the FIRM can be used to recreate the flood profile within 0.5 foot. Refer to Appendix C, Subsection C.6.3 for further guidance on BFE plotting. K.4.2.5 Cross Sections [February 2002] Cross sections shall be shown on the FIRM for all watercourses for which regulatory floodways have been determined. Cross-section locations and designations must correspond exactly to those shown on the Flood Profiles and in the Floodway Data tables presented in the FIS report. The distances between cross sections and those between cross sections and physical features shown on the FIRM must agree with those shown on the Profiles within a maximum tolerance of 5 percent of the distance measured on the FIRM or FBFM. K.4.2.6 Cross-Section Labeling [February 2002] Cross sections for each stream studied by detailed methods shall be labeled alphabetically from the downstream to the upstream limit of the study. At the request of a community and with the approval of the Project Officer, cross sections may also be labeled numerically. The typical numbering sequence is from the downstream to the upstream limit of study using the stream distance value at that location. Cross sections shall be labeled on the map with a hexagon at each end of the cross-section line. If there is not enough space to add a hexagon on each end, a hexagon may be placed on only one end. Cross-section hexagons shall be oriented so that the letter or number can be clearly read and is not upside down. If necessary to achieve this, the cross-section line should be trimmed or bent once it crosses the 0.2-percent-annual-chance boundary. Cross-section letters or numbers may follow the orientation of the hexagon or may be placed parallel to the bottom of the map sheet (0°). Cross-section lines shall cross the entire floodplain (past the limits of the 0.2-percent-annual- chance whenever possible). If the cross-section line cannot exit either side of the floodplain on the panel, the hexagon should be placed in the middle of the cross-section line and the line removed behind the hexagon. All graphic adjustments to cross sections shall remain separate from modeled cross-section locations that are stored in the FIRM GIS files. K.4.2.7 Limit of Detailed Study and Limit of Study [February 2002] Limit of Detailed Study labels shall be placed at the beginning and at the end of every area studied by detailed methods, when the terminus is indicated on the Flood Profile. Note that implied Limits of Detailed Study occur where the detailed study stops because of a stream confluence or when the stream exits the community on the FIRM. In these situations, it should not be labeled on the FIRM. Also note that this same rule applies to Flood Profiles. A Limit of Detailed Study shall be depicted as a thick, white line and labeled as a “Limit of Detailed Study” when it divides areas of different zone designations (e.g., Zone AE from Zone A). It shall be depicted as a thin, blue (orthophoto base) or black (vector base) line and labeled as previously stated when it is the terminus of the floodplain and there is no floodplain defined beyond it. Limit of Study labels should be used whenever the study (approximate or detailed) ends abruptly and has no corresponding Flood Profile. This situation occurs most often along streams studied by approximate methods but can also occur on backwater arms of detailed studied streams. K.4.2.8 Coastal Transects [February 2002] For coastal flood hazard studies, the assigned Mapping Partner shall perform an evaluation of the effects of waves accompanying the storm surge flood event on BFEs and hazard zones. The wave analyses performed shall be referenced in the FIS report and mapped on the FIRM. Wave transects shall be located with careful consideration of physical and cultural characteristics of the land so that they will closely represent conditions at those locations. Transect lines shall be delineated and labeled on the FIRM to identify the physical location of the wave transects described in the FIS report. The transect delineation on the FIRM should also help users to determine which wave transect analysis may influence or directly affect their property or area of interest. The wave effects mapped for any transect begin at the shoreline and end at the limits of 1-percent-annual-chance flood hazards, even though the actual transect line on the FIRM extends further seaward and landward of the flood hazard areas. K.4.2.9 Coastal Transect Labeling [February 2002] Coastal transect numbers shall be placed in a circle on both ends of the transect line. If both ends of the line cannot be labeled due to space limitations, one label at either end or a label placed in the middle of the transect line with the line removed behind the circle should be sufficient. Transect numbers may follow the orientation of the transect line or may be placed parallel to the bottom of the map sheet (0°). Transect numbering should generally proceed consecutively from north to south or west to east along a shoreline. New coastal transects inserted between existing transects should be numbered with an alphanumeric sequence (i.e., transects 5A and 5B might be inserted between existing transects 5 and 6). If constraints due to clutter limit the visibility of the transect lines on the FIRM, a Transect Location Map shall be used to portray the transects. Depending upon the coastal area to be shown, this map may be an 8 ½” x 11” page or 11”x17” foldout page placed in the FIS report. When a Transect Location Map is used, the FIRM GIS files include the transects in their correct geographic location relative to the other FIRM features if possible. Refer to Appendix J for additional information on the Transect Location Map. The table below provides examples of these standard flood hazard map features and their graphic portrayal on FIRMs. Two sets of examples, one for FIRMs that are orthophoto-based and one for those that are vector-based are provided. In general, the vector-based examples also apply to FIRMs that are produced manually. Specific exceptions to this are individually noted. Color shall be used to distinguish certain flood hazard features on orthophoto-based FIRMs. Bold type fonts surrounded by a white halo shall be used on orthophoto-based FIRMs. Medium type fonts shall be used on vector-based FIRMs where the gray shading used for flood hazard areas allows them to show more clearly. All flood hazard features presented in Table K-16 shall be shown on the FIRM in black unless otherwise indicated. Table K-16 Table K-16 Table K-16.

Arial CAPS PROFILE BASE LINE This note is used to identify a line on a map panel that indicates the modeled flow path of a stream when it does not coincide with the hydrographic feature shown on the map. The profile base line is used to represent channel distances as indicated on the Flood Profiles and Floodway Data tables. It is shown as a single line with one dash and labeled “Profile Base Line.” A profile base line may be added to detailed studied streams for the following reasons: The hydraulic model reflects a more direct flow path than the channel configuration shown on the map. This is most often the case when the stream displays extensive meandering; An island splits the river shoreline. The profile base line is used to identify the main channel; A lake through which a stream flows is present, and the reservoir routing modeling method has been used to effect a continuous Flood Profile; or The flood flow path is undefined on the map but the flow path has been modeled.

FIRMs clearly depict the different CBRS areas and their insurance prohibition dates with special map notes and symbologies. It should be noted that although FEMA shows CBRS areas on FIRMs, Congress is the only entity that may authorize a revision to CBRS boundaries. This Appendix uses the terms “Coastal Barriers” and “CBRS units.” These terms are intended to be inclusive of all classifications of Coastal Barriers within the CBRS, including areas designated as Otherwise Protected Areas (OPAs). For additional information regarding the CBRS, see Volume 2, Section 2.2 of these Guidelines. K.4.4.1 Coastal Barrier Resources System Boundaries [February 2002] The CBRS source maps show direct horizontal relationships between existing houses and the CBRS unit boundaries; these relationships must be maintained. Most often, the Coastal Barrier boundary has been delineated to keep houses that existed prior to the CBRS designation out of the designated Coastal Barrier. The CBRS source maps use thick lines to represent CBRS unit boundaries. Although standard cartographic practice is to follow the center of a boundary, if the boundary has a direct relationship with a linework feature (such as being against the edge of a road), that relationship must be maintained, even if it means the edge of the boundary line shown on the CBRS source map will be used. Boundary lines must be shown to differentiate between contiguous barriers of different classifications, because each CBRS classification carries a different insurance prohibition. All barriers must be labeled or identified by notes that identify the CBRS classification of each area. K.4.4.2 Map Screens for Coastal Barrier Resources System Areas [February 2002] Although there are several different types of Coastal Barriers, there are currently two unique map screens. Coastal Barriers shall be portrayed with the two map symbols shown below to differentiate between CBRS and OPA units, which contain differing prohibitions. The CBRS and OPA prohibition dates (i.e., the date that the CBRS or OPA area was originally designated) shall be shown within each separate CBRS and OPA unit to assist users in determining the proper insurance prohibition date for each unit. CBRS Unit, OPA UnitCBRS unit OPA unit FIRMs prepared after 1991 and prior to November 2000 show three unique map screens to reflect the three classifications of CBRS units. The three screens are as follows: 1983 Coastal Barriers, 1990 or Later Coastal Barriers, 1991 or Later Otherwise Protected Areas1983 1990 or later 1991 or later Coastal Barriers Coastal Barriers Otherwise Protected Areas Because the official CBRS source maps may show CBRS boundaries open to the sea, CBRS screens should not be terminated at shorelines unless the shoreline is coincident with the CBRS or OPA boundary. The boundaries and screens shall extend into the open water to the edge of the SFHA screen unless the Coastal Barrier boundary is closed on the official CBRS map and includes areas beyond the limit of the SFHA screen. K.4.4.3 Coastal Barrier Notes for the Body of the FIRM [April 2003] All separate CBRS areas on a FIRM shall be labeled with the appropriate identification note showing the prohibition date associated with that CBRS area. The assigned Mapping Partner shall use the abbreviated CBRS identification notes on the body of the FIRM and shall place a Coastal Barrier Legend below the Notes to User section of the FIRM border. At its discretion, the assigned Mapping Partner may place the Coastal Barrier Legend on the body of the map if there is insufficient space in the border. When there is insufficient space in the border and on the body of the FIRM to place the Coastal Barrier Legend, the full CBRS identification note shall be placed on the body of the FIRM within the CBRS area instead of the abbreviated CBRS note, and the Coastal Barrier Legend will not be used. See Subsection K.5.1.2 for more on the specifications of the Coastal Barrier Legend. Table K-18 contains abbreviated and full CBRS identification notes. CBRS identification notes, whether abbreviated or full, shall be located, whenever possible, on or near the land area, and shall not overprint existing base or floodplain features. When the note cannot be located on the land area because of space and clarity considerations, the note shall be placed in the open water within the CBRS screen, near the land area. When the note cannot be placed within the CBRS screen without creating overprints, the note shall be leadered to the land area. Table K-18.

The community map repository should be consulted for possible updated or additional flood hazard information. This note shall be shown on all FIRM panels. 10 Pt. Arial CLC (key words bold) To obtain more detailed information in areas where Base Flood Elevations (BFEs) and/or floodways have been determined, users are encouraged to consult the Flood Profiles and Floodway Data and/or Summary of Stillwater Elevations tables contained within the Flood Insurance Study (FIS) report that accompanies this FIRM. Users should be aware that BFEs shown on the FIRM represent rounded whole-foot elevations. These BFEs are intended for flood insurance rating purposes only and should not be used as the sole source of flood elevation information. Accordingly, flood elevation data presented in the FIS report should be utilized in conjunction with the FIRM for purposes of construction and/or floodplain management. This note shall be used to inform the user that supplemental flood elevation information is located within the FIS report. It shall be omitted from the Notes to User if the FIRM is not accompanied by an FIS report. A modified version of this note, shown below, is used on FIRM and FIS report combination panels. 10 Pt.
