GENERAL NOTES:

1. THE WORK SHOWN ON THESE PLANS INCLUDE THREE TASKS FOR THE USFS SOURGRASS WATER SYSTEM ON THE CALAVERAS RANGER DISTRICT, STANISLAUS NATIONAL FOREST. THE

THREE TASKS ARE:

A. TASK 1: PLACE 3900' OF NEW SUPPLY WATERLINE FROM HUMMINGBIRD SPRING (SOURCE) TO WATER TANK (STORAGE)

B. TASK 2: PLACE TWO PRESSURE EQUALIZATION TANKS ON THE DISTRIBUTION WATERLINE BETWEEN THE WATER TANK AND FIRST DISTRIBUTION POINT (SOURGRASS DAY USE AREA).

REPLUMB TWO EXISTING PRESSURE REDUCING VALVES IN THE SOURGRASS DAY USE AREA, AND RECONNECT WATERLINE AFTER VALVE REMOVAL.

C. TASK 3 (OPTION ITEM): SEAL (E) 10,000 GALLON CONCRETE WATER TANK

2. WORK ON TASKS 2 AND 3 SHALL NOT, BE STARTED UNTIL SEPTEMBER 7,2021. WORK ON TASK 1 CAN BE PERFORMED ANYTIME AFTER CONTRACT AWARD BUT SHALL BE COMPLETED PRIOR

TO COMPLETION OF TASK 1 FOR PURPOSES OF TESTING THE ENTIRE SYSTEM.
