NOTE:

1. Repair all rills or gullies and properly compact prior to installation.

2. Install fiber rolls along slope contours. For any 20' section of fiber roll, do not allow the fiber roll to vary more than 5% from level.

3. Stake fiber rolls in place with 1" x 1" or 1 "f?J wood stakes. Space stakes 4' o.c. max. on slopes and 2' o.c. max. culverts. Stake fiber rolls 6-inches from each end.

4. Drive stakes into undisturbed soil at least 12" deep.

Expose stakes 2" above top of fiber roll.

5. For fiber rolls on bare soil, construct trenches parallel to the contour. Place fiber rolls in continuous contact with trench bottom and sides. Tamp soil backfill against upstream side of fiber roll to ensure storm water is forced to flow through fiber roll rather than under it.

6. Place fiber rolls all the way around the inlet when the disturbance is on both the road and around the culvert and all water entering the culvert is crossing the disturbance.

STATE PROJECT

NOTE:

1. Erect all project advance warning signs before starting construction work.

2. Not all details shown on the temporary traffic control sheets may be applicable to this project. The Contractor may add or delete information and details in this traffic control plan as necessary to accommodate actual operations.

3. Where advance warning signs, placed as shown, interfere with permanent signs, locate the warning signs as determined by the CO for best results. Vary messages as required.

4. Additional or different message signs may be required to fit the actual construction conditions.

5. Install advisory speed plates under the W20 series warning signs as needed to indicate a maximum recommended speed through the construction area.

6. Ensure all sign supports exposed to impact by traffic meet the requirements of NCHRP-350 or MASH for crashworthiness.

7. Maintain two-way traffic during all non-work hours except as approved by the CO.

8. Do not store traffic control devices along the roadway when not in use. Cover post-mounted signs when not applicable.

9. If W20-1 is placed on a roadway other than that on which the actual construction work occurs, include a supplementary plaque indicating the name of the road on which the construction does occur (applies to major roads only).

10. The message on the W20-1 signs may be "ROAD WORK AHEAD" or may specify the distance to the work area in feet or in miles. Install an additional W20-1 sign when approach speeds exceed 50 MPH. When used place the two W20-1 signs "B" feet apart according to the Sign Spacing Table.

11. For work zones that are 2 miles or more in length, install G20-1 signs at each end of the project. Show the distance on the G20-1 sign to the nearest whole mile.

12. If signing on a roadway under a jurisdiction other than the client agency, verify that an encroachment permit has been obtained.

13. State standards may be used as an alternative if approved by the CO.

14. Refer to the Section 635 of the Special Contract Requirements for allowable retroreflective sheeting types.

NOTE:

1. Use this layout only if sufficient gaps in oncoming traffic exist for traffic that must yield, and if drivers from both directions are able to see approaching traffic through and beyond the work site.

2. Final location and spacing of signs and devices may be changed to fit field conditions as approved by the CO.

3. If closure is completely within the project limits, eliminate the "ROAD WORK AHEAD" (W20-1) and "END ROAD WORK" (G20-2) signs.

4. If the surface is paved, install yield lines that comply with Section 3B.16 of the MUTCD.

5. Use the "YIELD AHEAD" (W3-2) sign when approach speeds exceed

50 MPH.

6. For project specific minimum width, refer to Special Contract Requirements, Section 156.

STATE PROJECT

NOTE:

1. When a delineator falls within a cross road or approach, the delineator may be moved in either direction a distance not to exceed one quarter of the normal spacing. Eliminate the delineator if this allowance is exceeded.

2. Place delineators 2 feet from the edge of design shoulder unless otherwise specified .

3. Install delineators behind the rail at guardrail locations.

Either drive the delineator in line with the guardrail posts or mount a shorter delineator onto the guardrail post as shown on this sheet.

4. When the contract does not provide for the construction of the ultimate pavement, allow for the thickness of base and pavement to be placed later when establishing the elevation of the traffic delineators.

5. Use the current edition of the Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) as a guide for delineation layout.

Spacing for a specific curve may be interpolated from the table, or calculated using the formula:

Spacing = 3 v R-50.

The minimum spacing should be 20 feet.

Curve spacing should not exceed 300 feet.
