NOT TO SCALE

Water Valve & Meter Relocation Notes:

Coordinate design with City and Borough of Juneau (CBJ) and obtain CBJ approval on all plans. Final design to be submitted to USFS for approval before proceeding with construction.

Work includes, but is not limited to:

Relocate the meter and valve out of roadway and bike path, onto shoulder as approved by CBJ and USFS.

House the valve in standard water utility box for a 6” compound meter with a backflow preventer. The box shall lock on two sides and open from either side.

Provide a 4” thick concrete pad to mount the housing structure to. Include an opening in the concrete to allow for the water lines to pass freely with a 1” clearance without being in contact with the concrete, or as approved by CBJ.

Existing water lines and sewer lines are shown on the drawings based on available information. The actual location and sizes may vary. The Contractor shall be responsible for determining the actual location of existing service line by potholing if necessary. Protect all existing lines from damage.

Coordinate with CBJ Lead Meter Technician, Public Works Water Utility (907-789-0997) to have the meter rebuilt by CBJ after it is installed and to have the meter transmitters reconnected.

Install water line per CBJ requirements Coordinate water shut-off period with CBJ and USFS. Work to be completed from Oct 1- April 15. Provide min. 2 weeks notice to CO prior to shutting off water.

Maintain access for emergency vehicles at all times, and work with other services to minimize delays.
