Sign Board Material.-Two-inch redwood laminated on edge, 3/4-inch MDO with 60-60 black overlay, or any of the listed substrates on pages 56 and 57.

Sign Board Fabrication.-Whenever signs with glue-laminated joints are
constructed, the joints should be doweled and a marine type glue used. Signs that
have two or more glue joints should be backed with an appropriate material to prevent
cupping, warping, or other distortion.

5. Sign Face.-Plywood sign board should be treated with Scotchcal, or equivalent, film or painted surface; color of film should be 3M, Recreation Brown; color of paint should be Pantone 1685U, or equivalent, and Pantone 2905U, or equivalent. Redwood sign and board should be stained with Olympic Stain 707, and the blue portion should be painted with Pantone 2905U, or equivalent.

Sign Supports.-Stained redwood or treated Douglas fir posts, 4 by 6 inches. Posts should be buried and concrete encased at least 36 inches below ground level. The stain color should be Olympic Stain 713, or equivalent. Signs may also be attached to buildings, bridges, dams, etc., where appropriate. Supports should be flush with the top of the sign.

Method of Anchoring Sign.-One-half-inch-diameter carriage bolts long enough to
extend from the sign face through the back of the posts. The bolts should not
protrude more than 3/4 inch beyond the signpost. Large washers and nuts should be
used to secure the bolts. The rounded bolt heads on the sign surface should be treated
with a matching paint or stick-on film. Use of vandal-proof nuts is encouraged.

Lettering.-Lettering can be of Scotchlite film, or equivalent, routed or flat, and
painted or painted with a silk screen. Scotchlite White, or equivalent, should be used
for the film letters; Pantone 607U, or equivalent, should be used on the painted
letters. Letter size should be determined from information contained in chapter V.

NOTE: The graphic examples in this chapter use blue (Pantone Color Matching System 2905U) for the background color. However, brown (Pantone 4695U) may also be used. In either case, the lettering for text and border should always be white (Pantone 607U). In addition, an Egyptian letter style has been used for the examples; however, other letter styles may also be used.

An example for this type of sign is shown on the following page. In signing situations where Reclamation is the dominant entity, sign designs should closely follow the guidelines shown for Design Type B1. When another agency has the dominant role, that agency should design a sign that will adequately identify the Bureau of Reclamation. However, use of Reclamation sign designs should be encouraged.
