1. CALL BEFORE YOU DIG: 1-800-342-1585. THIS DRAWING MAY NOT INCLUDE ALL OF THE UTILITIES PRESENT AT THE SITE. IT IS THE

CONTRACTOR'S RESPONSIBILITY TO LOCATE AND PROTECT ALL ABOVE-GRADE AND BELOW-GRADE UTILITIES.

2. THE CONTRACTOR SHALL SCHEDULE ALL INSPECTIONS REQUIRED BY THE UTILITY COMPANIES WHILE WORKING AROUND UTILITIES.

3. THE CONTRACTOR IS RESPONSIBLE FOR SITE CONTROLS AND THE HEALTH AND SAFETY OF THEIR EMPLOYEES AT ALL TIMES.

4. THE CONTRACTOR SHALL NOT DEVIATE FROM THE LIMITS AND TOLERANCES THAT ARE IDENTIFIED IN THE PLANS AND SPECIFICATIONS

WITHOUT APPROVAL FROM THE GOVERNMENT.

5. THESE PLANS AND PROJECT SPECIFICATIONS CONSTITUTE THE ENGINEERING DESIGN FOR CHANNEL REALIGNMENT AND FLOODPLAIN

RESTORATION. FIELD ADJUSTMENTS ARE ANTICIPATED DUE TO THE DYNAMICS OF EAST FORK POTLATCH RIVER AND ITS FLOODPLAIN. THE

GOVERNMENT SHALL BE CONSULTED ON ALL DEVIATIONS FROM THE PROJECT DESIGN THAT ARE BEYOND THE ALLOWABLE TOLERANCES.

6. ALL EXISTING MATURE VEGETATION SHALL BE PROTECTED AND REMAIN UNDISTURBED UNLESS DIRECTED OTHERWISE BY THE

GOVERNMENT'S FIELD REPRESENTATIVE OR AS NOTED ON PLANS.

7. THE CONTRACTOR IS RESPONSIBLE FOR COMPILING AND PROVIDING TO THE GOVERNMENT A SWPPP AND A HEALTH AND SAFETY PLAN AT

LEAST TWO (2) WEEKS PRIOR TO THE START OF CONSTRUCTION.

8. THE CONTRACTOR IS RESPONSIBLE FOR THE CONSTRUCTION GENERAL PERMIT (15 DAY WAIT). THE GOVERNMENT IS RESPONSIBLE FOR ALL

OTHER APPLICABLE PERMITS AND WILL PROVIDE THE NECESSARY DOCUMENTATION TO THE CONTRACTOR PRIOR TO THE START OF

CONSTRUCTION.

9. EXISTING CONDITIONS ARE BASED ON A COMPILATION OF LIDAR AND GPS SURVEY. SLIGHT DISCREPANCIES AT THE TRANSITION OF THE TWO

DATA BOUNDARIES ARE PRESENT AND LOCATIONS SHALL BE TREATED AS APPROXIMATE. THE DESIGN GRADES ARE INTENDED TO TIE INTO

THE EXISTING GROUND. ADJUST THE TIE INS IN THE FIELD AS NEEDED BASED ON ACTUAL CONDITIONS.

10. SURVEY DATA AND CONTROL POINTS ARE IDAHO STATE PLANE (ISP), NAD 83, ZONE WEST, US FT. VERTICAL CONTROL IS NAVD 88.

11. ANY LEFT AND RIGHT BANK DESIGNATIONS INDICATED ON THE PLANS ARE LOOKING DOWNSTREAM.

12. ANY EXISTING SURFACES WITHIN 0.5 FEET OF THE DESIGN ELEVATION SHALL NOT BE DISTURBED UNLESS REQUESTED BY THE

GOVERNMENT.
