The emblem can also be printed black on white or white on black. The emblem colors are specified in paragraph E.2.c. (above). One-color versions may also be used. If a one-color version is used, the emblem can only be used in the positive form. If the emblem is to be used against a dark background in which the emblem border would be lost, the emblem should be superimposed on a white oval, so the emblem border will stand out. 1. Seals/Emblems.-Signs and posters may carry both the Interior seal and Reclamation emblem. They must be either vertically placed in the upper, left-hand corner (Interior above, Reclamation below) or set independently on either side of the sign in a convenient location (Interior left, Reclamation right). Refer to Design Types B1a and B1b. a. On fire prevention regulatory signs, only the Reclamation emblem should be b. C. On special purpose posters, only the Reclamation emblem should be used. It should be placed in the lower, right-hand corner. A "reversed" or negative emblem will not be used. Instead, use the positive emblem on an oval patch of white, slightly larger than the emblem. On elongated signs, the Reclamation emblem should be used alone in a boxed area at the top or the bottom of the sign. 2. Agency Identification.—The standard Reclamation emblem is the only symbol used to identify the Bureau of Reclamation. It must not be modified. Use the Reclamation emblem on all entrances to designated locations on Reclamation lands. Identify Reclamation as an agency of the Department of the Interior. M. Letter Styles: The letter styles selected for most Reclamation signs are Ancient Egyptian and Helvetica Medium; however, each office may select letter styles and a typeface that meet their individual needs. The only exceptions are standard roadway signs that will conform to MUTCD standards and interpretive signs that will be established during the planning phase of development. If signs are provided in conjunction with other agencies, their choice of letter styles should be taken in consideration. Most signs will use Ancient Egyptian letter styles, particularly major and minor identification signs. Signs requiring a large number of words, such as information signs, can be lettered with Helvetica Medium. Sans serif lettering with consistent stroke width is easier for people with visual impairments to read. In situations where it is imperative that a message be communicated, sans serif should be used. 1. Typeface.-Helvetica, Roman, Bold, Italic, and other forms may be used. Italic is to be used sparingly and for special effect. 2. Upper and Lowercase.-Use of normal upper and lowercase letters throughout the sign is preferred. All uppercase will be used only for sign headline copy and for special emphasis. In all cases, body copy will follow normal upper and lowercase rules. a. Typeface: Several additional typefaces commonly used on Reclamation signs are or could be: (1) News Gothic Bold. A sans serif typeface comparable to the Helvetica Bold, but less heavy stroke. Used primarily on administrative, information, and road direction signs. Used to spell out United States Department of the Interior and Bureau of Reclamation. Used as body type for sign message. (2) Souvenir Demi. A moderate, serif, italic typeface. (3) Helvetica. A strong, easily read, sans serif typeface. (4) Egyptian. Easily read letter style that can be used on major identification signs. N. Signposts and Bases: Where applicable, signposts used on standard highway regulatory, warning, and directional signs should be made of treated, 4- by 6-inch Douglas fir or redwood. Breakaway-type mounting posts should be considered, when feasible. A single post should be used for signs up to 3 feet in length and double posts for signs more than 3 feet long. Signs should be attached to posts in a manner that does not interfere with message legibility, while remaining easily removable for maintenance. When signs are mounted on dams, buildings, or other structures, the need for posts will be eliminated. The signs should be bolted to the structure, allowing a space of several inches between the back of the sign and the wall face to give the sign a raised appearance. For signs located within or immediately adjacent to campgrounds and day-use areas that have grills and fire pits, it may be practical to use metal steel or reinforced aluminum for sign supports. In these instances, all metal surfaces should be painted or galvanized. Identification and interpretive signs should have bases that support the design character of the area. Guidelines for the base height and angle have been established by the Uniform Federal Accessibility Standards and the Americans with Disabilities Act Accessibility Guidelines. However, base designs should be approved by the area office sign coordinator or by the area office sign coordinator in conjunction with the regional sign coordinator and the public affairs officer and, where appropriate, the regional accessibility coordinator. The location of all signs along roadways should comply with MUTCD standards. The following chart shows the approximate required distance between signs and the required distance of advance warning of directional signs before intersections: There are no standards for the location of pedestrian signs, but their physical surroundings play an important role. Pedestrian signs should be highly visible and not obstructed by vegetation or physical features of the area. Care should be taken to ensure that signs directed to one activity do not interfere with another activity. Safety of the visitor should always be a consideration when determining both the message and location of signs. 1. Placement and Installation.—Uniformity of placement and installation helps users to see the signs and determine where the directed action is to take place. Select locations that maximize the opportunity for the sign to convey its intended message. a. Placement: As a general rule, with the exception of the "No Passing" pennant, place signs on the right-hand side of the roadway, as close to the standard location as possible. Consider the following Guidelines when selecting sign installation locations: (1) Place signs where they provide adequate time for viewer response, (2) Select locations that minimize viewing obstructions. Some common (a) Dips in the roadway or trail. (b) Just beyond the crest of a hill. (c) Where the sign may interfere with the normal operation of the facility. (d) Too close to trees or other foliage that could cover the face of the sign. (3) Place the sign within the viewer's "cone of vision." (a) As speed increases, driver concentration increases. (b) As speed decreases, driver concentration wanes. At 25 mph, the natural eye focus point lies 600 feet ahead of the car. At 45 mph, it lies 1,200 feet ahead. (c) As speed increases, the driver's peripheral vision decreases. On low- (d) As speed increases, the driver's ability to focus on foreground detail decreases. At 40 mph, the closest point of clear vision lies 80 feet ahead of the car. At 60 mph, the driver can see clearly only that detail within an area 110 to 1,400 feet in front of the car and within that 40degree "cone of vision."
