GENERAL NOTES

1. THE STONE PROTECTION DESIGN SHALL BE CONSTRUCTED BASED ON ELEVATIONS AND OFFSETS

MEASURED FROM A SPECIFIED CONSTRUCTION LINE.

2. CONSTRUCTION OFFSETS ARE MEASURED PERPENDICULAR TO THE CONSTRUCTION LINE

SEGMENT UNLESS OTHERWISE NOTED.

3. OFFSETS SHOWN ON CROSS SECTIONS ARE FOR THE STATION AND ALIGNMENTS SHOWN AND

ARE SUBJECT TO REVISIONS TO CONFORM TO CHANGED SITE CONDITIONS.

SURVEY NOTES

1. GRID COORDINATES REFER TO THE CALIFORNIA STATE PLANE COORDINATE SYSTEM ZONE 2, NAD83

(2007.00) US SURVEY FEET.

2. ELEVATIONS ARE REFERENCED TO THE NORTH AMERICAN VERTICAL DATUM OF 1988 (NAVD88), FEET.

3. TOPOGRAPHY AND BATHYMETRY WAS DEVELOPED FROM TOPOBATHYMETRIC LIDAR ON OCTOBER

22-23, 2017 WHEN FLOWS WERE AT APPROXIMATELY 2,000 CUBIC FEET PER SECOND.

4. SINGLE BEAM BATHYMETRIC SURVEY COMPLETED IN DECEMBER 2017 THROUGH FEBRUARY 2018

SUPPLEMENTS THE TOPOBATHYMETRIC LIDAR SURVEY WHERE DEPTHS EXCEEDED 12 FEET DURING

THE TOPOBATHYMETRIC SURVEY.

5. JULY 2019 FIELD SURVEY IDENTIFIED INFRASTRUCTURE COMPONENTS IDENTIFIED IN THE PLANS.

6. FINISHED CONTOURS ON SITE PLAN AND TOPOGRAPHY SHEETS ARE SHOWN AT ONE-FOOT VERTICAL

INTERVALS BASED ON THE DESIGN ELEVATIONS WITHIN THE PROJECT FOOTPRINT, AND TWO-FOOT

VERTICAL INTERVALS BASED ON EXISTING CONDITIONS.

7. CONTROL POINTS FOR THE SITE ARE SHOWN ON THE INDEX SHEET ALONG WITH CONTROL COORDINATE

TABULATIONS, ELEVATIONS, AND DESCRIPTIONS.

8. TEMPORARY CONSTRUCTION REFERENCE LINES, TO BE SET BY THE CONTRACTOR, ARE SHOWN ON THE

PLAN AND TOPOGRAPHY SHEETS.

LOWER AMERICAN RIVER STAGE DATA

1. THE STAGE (WATER SURFACE ELEVATION) DATA TABLE (SHOWN ON THIS SHEET) IS PROVIDED FOR

INFORMATION ONLY.

2. THE STAGE DATA TABLE PROVIDES MONTHLY EXCEEDANCE STATISTICS FOR STAGE AT THE H

STREET BRIDGE. THE EXCEEDANCE DATA IS FROM HOURLY STAGE ELEVATIONS AT THE H STREET

BRIDGE BETWEEN JULY 1995 AND JULY 2020 AT THE STATE OF CALIFORNIA GAGE STATION.

3. WATER SURFACE ELEVATIONS VARY THROUGH THE SITE. THE H-STREET GAGE IS LOCATED AT

H-STREET NEAR THE UPSTREAM EXTENT OF THE PROJECT. WATER LEVELS AT THE DOWNSTREAM

EXTENT ARE TYPICALLY BETWEEN 1.0 TO 1.5 FEET LOWER THAN OBSERVED VALUES AT H-STREET

GAGE. BACKWATER CONDITIONS FROM HIGH SACRAMENTO RIVER WATER LEVELS MAY REDUCE

THIS DIFFERENCE.

4. THE LOWER AMERICAN RIVER EXPERIENCES WIDE VARIATIONS IN FLOW AND RIVER STAGE THAT

SHOULD BE EXPECTED DURING THE PROJECT CONSTRUCTION PERIOD. THE CONTRACTOR SHOULD

CONSULT RIVER FLOW AND STAGE INFORMATION DURING THE BIDDING, PLANNING, AND

EXECUTION OF THE WORK.

5. THE STAGE AT H STREET CAN BE AFFECTED BY HIGH FLOW CONDITIONS IN THE SACRAMENTO

RIVER AS WELL AS FLOW ON THE AMERICAN RIVER.

6. THE FOLLOWING LINK CAN BE USED TO ACCESS CURRENT FLOW AND STAGE DATA FOR THE

LOWER AMERICAN RIVER AT USGS GAGE NO. 11446500 (AMERICAN RIVER AT FAIR OAKS, CA):

HTTPS://WATERDATA.USGS.GOV/USA/NWIS/UV?SITE_NO=11446500

7. THE FOLLOWING LINK CAN BE USED TO ACCESS UP TO 5 DAYS OF FORECASTED STAGE DATA FOR

THE LOWER AMERICAN RIVER AT THE H STREET BRIDGE FROM THE CALIFORNIA NEVADA RIVER

FORECAST CENTER (SAMC1): HTTPS://WWW.CNRFC.NOAA.GOV/GRAPHICALRVF.PHP?ID=SAMC1

8. CONTRACTOR OPERATIONS DURING THE CONSTRUCTION PERIOD MAY BE IMPACTED BY EXTREME

HIGH OR LOW RIVER LEVELS DUE TO FLOODING, DROUGHT, AND/OR OPERATION OF UPSTREAM

DAM RELEASES. IT IS THE CONTRACTOR'S RESPONSIBILITY TO MONITOR LOWER AMERICAN RIVER

FLOW CONDITIONS ON A DAILY BASIS AND TO IMPLEMENT PROCEDURES TO PROTECT THE WORK, EQUIPMENT, AND MATERIALS.

9. THE DATA TABLE PROVIDED ON THIS SHEET AND THE REFERENCED WEBSITES ARE SOLELY FOR

THE INFORMATION OF THE CONTRACTOR IN TIMING CONSTRUCTION OPERATIONS TO PREPARE

FOR FLOOD EVENTS AND IN MAKING PROVISIONS FOR PROTECTING THE WORK. USACE DOES NOT

GUARANTEE THE RELIABILITY OR ACCURACY OF ANY OF THE DATA AND ASSUMES NO

RESPONSIBILITY FOR ANY DEDUCTIONS, INTERPRETATIONS, OR CONCLUSIONS WHICH MAY BE

DERIVED FROM THE DATA.
