01/2022

LOGGING AND MAINTENANCE OPERATIONS SIGNING STANDARDS

All signs must be manufactured & installed as specified in the latest version of the Federal Highway Administration

(FHWA) "Manual on Uniform Traffic Control Devices" (MUTCD) 2009 MUTCD with Revisions 1 and 2, May

2012 - Knowledge - FHWA MUTCD (dot.gov) and the FS publication "Standards for Forest Service Signs &

Posters"( EM 7100-15) stelprd3810021.pdf (usda.gov) . Specific information regarding temporary traffic contol can be found in Chapter 4 of the EM 7100-15 or Part 6 of the MUTCD.

SIGN STANDARDS

SHAPE & COLOR: Generally, signs for logging and maintenance operations are considered temporary traffic control and are either diamond-shaped or rectangular. All signs shall have a black legend and border on an orange retroreflective background unless shown otherwise. Hand-painted, homemade signs are not acceptable. Fluorescent paint is not reflectorized.

SUBSTRATE: Sign substrate material may be High Density Overlay (HDO) Plywood, Aluminum, Fiberglass

Reinforced Plastic, Corrugated Plastic or Roll-up Fabrics.

LEGEND: All lettering shall be minimum Series "C" alphabet, conforming to Standard Alphabets for Highway

Signs. Letter size is also a function of speed - use letter size and word messages as specified in MUTCD and EM-

7100-15.

SIGN PLACEMENT

Signs are to be installed in locations as agreed to in the Traffic Control Plan. All signs are to be removed, covered, or folded when operations are not in progress or the sign message is not applicable. Signs should generally be located on the right-hand side of the roadway. When special emphasis is needed, signs may be placed on both the left and right sides of the road. Sign message shall be clearly visible to road users, mounted on posts or portable sign stands.

SIGN LOCATION

Signs must be located 100-500 feet prior to the temporary traffic control activity based on speed, (both ends if a through road) to warn traffic and allow for adequate perception and reaction time of the driver as listed in Figure 2:

Table 4A.1 (EM7100-15). These numbers are intended for guidance purposes only and should be applied with engineering judgement.

SIGN SUPPORTS

POSTS: Signs are to be mounted on separate posts. Supplemental signs such as Speed Advisory plates are to be mounted on the same post as the primary sign. Do not mount signs on trees or other signs. Posts may be wood, metal, carsonite or similar material and must meet breakaway standards if within the clear zone. Wood posts that are 4 inches by 4 inches or have a cross-sectional area of 24 square inches or smaller are considered to meet breakaway standards when installed in normal soil conditions.

TEMPORARY/PORTABLE SUPPORTS: Portable supports may be used for short-term, short-duration, and mobile conditions. All portable supports must meet MUTCD standards, including breakaway. These must be a minimum of 1 foot above the traveled way.

Figure 3: Examples of Temporary/Portable Supports

SIGN SIZES

Sign sizes are dependent on speed of the road and road type as shown in Figure 4: Table 4-1 (EM7100-15) of which a portion of the table is shown below. Larger signs may be used whenever necessary for greater legibility or emphasis.

Figure 4: Table 4-1 Temporary Traffic Control Sign Sizes

TYPICAL SIGNS

The signs below are not a complete listing of signs that may be needed. The decision to use a particular traffic control device at a specific location should be made by either an engineering study or application of engineering judgement. Sign numbers are from MUTCD. An ‘F’ before the sign number indicates a Forest Service sign and the last number indicates sign size, generally in the horizontal direction. The sign sizes in the signs below are for low-volume roads with a speed of less than 35 mph. Larger signs may be used whenever necessary for greater legibility or emphasis.

B(T)6.33 WARNING SIGN PLACEMENT

Contract Name: Bovee Restoration IRSC Contract #:12363N23Q4296

Unless otherwise agreed, warning signs will be placed at the following locations:

A) Signs will be placed at the beginning of system roads and trails open to the public, per the current MVUM, where active hauling and/or forwarding is taking place. If it is a through road or trail, both ends of the road or trail will be signed to the extent where active hauling and/or forwarding is taking place.

B) Signs will be placed at the beginning of system roads and trails where active logging operations are within 100 feet of roads or trails open to the public, per the current

MVUM. If it is a through road or trail, both ends of the road or trail will be signed to the extent where active logging opertations are taking place. If signs required under paragraph A already cover these roads or trails, no additional signs will be needed.

C) On roads without Forest Service jurisdiction, the Purchaser shall consult with the appropriate regulating agency (i.e. County or State) to determine signing requirements, but must at minimum sign according to paragraph A and B.

D) Other Specific Locations: If it is determined that signage cannot effectively maintain safety for operators and the public, and temporary road closures are required, immediate consultation with the COR is necessary to begin the closure process. Once closed, signage requirements will be the same as above but will feature “Road Closed” warnings, and barriers will be placed in agreed-upon locations.

Agreement: Purchaser shall furnish, install and maintain all temporary traffic controls as defined in this document.
