COORDINATE SYSTEM : Alaska Zone 4 SPCS NAD83 2011

EPOCH DATE : 2010.0000

VERTICAL DATUM : Orthometric elevations based on the NAVD88 GEOID12b

To precisely check distances between points as measured on the ground, inverse the state plane coordinates and divide the computed distance by a mean combined factor of the two points.

NOTE:

1. See Erosion Control Section for temporary culvert diameter, riprap class, channel dimensions and quantities.

2. Use plastic liner or riprap along the entire length and width of the temporary diversion channel.

3. Construct channel at a minimum grade of 0.5 percent.

4. Do not construct with longitudinal joints if using a plastic liner. Bury the upstream edge of the liner a minimum of 6" deep and secure with riprap or sandbags.

5. When specified replace the portion of the diversion channel through the roadway embankment with temporary culvert. Compact temporary culvert backfill using one of the methods listed in Subsection 204.ll(a).

NOTE:

1. Alternate preassembled silt fence options will be allowed as long as specified dimensions are satisfied. Follow manufacturer's recommendations for installation procedures.

All types must ensure silt fence remains attached to, and does not slide down, supporting posts.

2. Install silt fence to follow the ground contours as closely as possible.

3. Curve ends of silt fence upgrade to prevent water from running around the ends .

The fill heights in the table are for helical lockseam and welded seam pipe only.

Fill heights for culvert pipe with annular corrugations are more restrictive than those of helical lockseam and welded seam pipe.

Obtain approval before furnishing annular corrugation pipe.
