1) ALL WATER LINES ARE UNDER THE JOINT JURISDICTION OF OREGON

DEPARTMENT OF FISH AND WILDLIFE (ODFW) AND THE US FOREST SERVICE.

2) EXACT LOCATION OF 2" WATERLINE BEYOND THE VISIBLE VALVE IS UNKNOWN.

WATERLINE IS ASSUMED TO CROSS THE ASPHALT ROADWAY ON THE WEST SIDE

OF THE EXISTING VALVE BOX AS SHOWN.

3) CONTRACTOR SHALL ENSURE THE PROTECTION OF ALL WATERLINES AND

UTILITIES IN THE PROJECT AREA. THE CONTRACTOR SHALL SUBMIT A

CONTINGENCY PLAN FOR REPAIRING THE EXISTING 36" CMP IF DAMAGED DUE TO

EQUIPMENT OR DRILLING OPERATIONS IN THE AREA, IN WRITING TO THE CO AT

LEAST 30 DAYS PRIOR TO CONSTRUCTION. AT A MINIMUM THE CONTRACTOR'S

PLAN SHALL INCLUDE THE FOLLOWING ON THE DAY OF PILE DRILLING:

- (2) X 20' SECTIONS OF 36" HDPE PIPE ON SITE TO REPLACE ANY DAMAGED

SECTION(S) OF THE EXISTING CMP.

- PROPER COUPLINGS TO CONNECT NEW HDPE PIPE TO OLD CMP.

- EQUIPMENT AND PERSONNEL ON SITE TO QUICKLY EXCAVATE, REMOVE

AND REPLACE DAMAGED PIPE SECTION(S) AS NEEDED.

- A WATER PUMP CAPABLE OF PUMPING 5000 CFM, WITH A MINIMUM OF

500 FEET OF HOSE. PUMP, INTAKE AND HOSE SHALL BE DISINFECTED.

CONTRACTOR SHALL CONSULT WITH THE CO AND ODFW PERSONNEL TO

ENSURE PROPER LOCATION OF PUMP AND HOSE ATTACHMENT TO FISH

HATCHERY DISTRIBUTION BOX.

- ADDITIONAL ROAD CLOSURE DEVICES IN THE AREA OF THE WATER PUMP

AND HOSE.

PAYMENT FOR ALL MATERIALS, INSTALLATION, AND INCIDENTALS ASSOCIATED

WITH CONTINGENCY PLAN TO REPAIR THE 36" WATERLINE SHALL BE MADE

UNDER PAY ITEM 61102D.

4) POWER AND TELEPHONE LINES MAY BE BURIED IN THIS AREA. LOCATING AND

PROTECTING ALL UTILITIES (PUBLIC & PRIVATE) IS THE RESPONSIBILITY OF THE

CONTRACTOR.

5) FOR WATER LINE HYDROSTATIC TESTING AND DISINFECTION CRITERIA, SEE

FSSS 611.

6) CONTRACTOR SHALL PROVIDE CALCULATIONS FOR ANTICIPATED EXPANSION

AND CONTRACTION OF 4" HDPE WATERLINE CROSSING THE BRIDGE, AND

PROVIDE ANY NECESSARY MITIGATION TO PREVENT DAMAGE TO THE

WATERLINE, SUPPORTS, BRIDGE AND APPURTENANCES.
