PROJECT DESCRIPTION

THIS PROJECT CONSISTS OF FURNISHING THE NECESSARY LABOR, EQUIPMENT

AND MATERIALS TO CONSTRUCT NEW WATER STORAGE RESERVOIRS (4 TOTAL)

ADJACENT TO AN EXISTING WATER SOURCES. THE WORK ASSOCIATED WITH

THIS CONTRACT INCLUDES:

CONSTRUCT A WATER STORAGE RESERVOIR, OVERFLOW CHANNEL AND

EARTHEN BERM; INCLUDING SITE PREPARATION, GRADING, EXCAVATION,

BACKFILLING AND COMPACTION.

CONSTRUCT NEW WATER PIPELINE, VALVES, DRAINS AND WATER

COLLECTION POINT.

CONSTRUCT NEW AGGREGATE-SURFACED ACCESS ROAD AND INSTALL

ROAD CLOSURE BARRIERS.

INSTALL RIPRAP APRONS FOR EROSION CONTROL AND SLOPE

STABILIZATION.

1. THE PURPOSE OF THIS SURVEY WAS TO COLLECT TOPOGRAPHIC AND SITE FEATURE INFORMATION IN THE VICINITY OF THE EAST BRANCH LIGHTS CREEK, FOR THE PURPOSE OF DEVELOPING AN OFF-CHANNEL WATER

SOURCE.

2. ALL DISTANCES AND ELEVATIONS ON THIS PLAT ARE SHOWN IN US SURVEY FEET. ALL BEARINGS ARE APPROXIMATED USING A COMPASS ON A SMARTPHONE. POINT COORDINATES ARE ASSUMED GRID.

3. THE CONTOUR INTERVAL SHOWN IS 1.0 US SURVEY FEET.

4. GEOGRAPHIC COORDINATES (WITH THE EXCEPTION OF ELEVATION) SHOWN WERE DETERMINED USING

RUDIMENTARY HANDHELD GPS.

5. APPROXIMATE GEOGRAPHIC POSITION FOR CONTROL POINT #1 (CP 1) IS AS FOLLOWS (DETERMINED FROM

GOOGLE EARTH IMAGE OF THE SITE).

APPROXIMATE GEOGRAPHIC POSITION FOR CP 1

LAT 40° 13' 12.70" N

LONG 120°43'04.10" W

ELEVATION = 5385.0 FT.

6. SITE CONTOURS, ROAD, AND FEATURE ELEVATIONS WERE ASSUMED AT THE TIME OF THE SURVEY; NO CORRECTION TO THE ACTUAL ELEVATIONS WERE MADE, NOR IS NECESSARY FOR THE PURPOSE OF THE DESIGN.

7. SITE TOPOGRAPHIC MAP WAS DEVELOPED USING AUTOCAD CIVIL 3D VER 2014. NO ADJUSTMENTS WERE MADE TO THE POINTS TAKEN, AS THE GRID WAS DEVELOPED ASSUMING NORTHING, EASTING, AND ELEVATION.

8. TOTAL AREA SURVEYED = 1.24 ACRES.

CONTROL POINT NOTE:

EACH CONTROL POINT WAS SET USING A #4 X

18" REBAR, HAMMERED IN PLACE AND FLUSH

WITH THE GROUND. A PLASTIC YELLOW CAP

WAS PLACED ONTO THE TOP OF THE REBAR,

AND THE CENTER OF THE YELLOW CAP WAS

IMPRINTED WITH A SMALL DIVOT TO MARK

THE CENTER POINT. PINK FLAGGING WAS TIED

TO THE REBAR, JUST BELOW GRADE. A

3-FOOT WOOD STAKE WAS USED TO MARK

THE LOCATION OF THE CONTROL POINT, AND

WAS SET 1-2 FEET FROM THE REBAR.

LOCATION OF EACH CONTROL POINT:

CP 1 - SET ON NATIVE GROUND, APPROXIMATELY 283 FEET

SOUTHEAST FROM ROAD NUMBER 27N09 (FROM CULVERT

INLET) AND 80 FEET EAST OF EAST BRANCH LIGHTS CREEK.

THIS POINT IS TO BE USED AS A BENCHMARK TO RESET

MISSING CONTROL OR TO SET NEW CONTROL.

CP 2 - SET ON ROAD SHOULDER, WHERE A

DECOMMISSIONED ROAD INTERSECTS ROAD NUMBER

27N09.

CP 3 - SET AT A WIDE PULLOUT ON THE ROAD SHOULDER OF

ROAD NUMBER 27N09, APPROXIMATELY 72 FEET WEST OF

THE CULVERT INLET.

CP 4 - SET ON NATIVE GROUND, APPROXIMATELY 188 FEET

NORTHEAST OF CP 1 AND APPROXIMATELY 180 FEET

SOUTHEAST OF THE SECTION CORNER MONUMENT. THIS

POINT IS TO BE USED AS A BENCHMARK TO RESET MISSING

CONTROL OR TO SET NEW CONTROL.

SECTION CORNER MONUMENT 2/3/10/11 - CORNER

MONUMENT LOCATED APPROXIMATELY 125 FEET

SOUTHEAST OF THE ROAD NUMBER 27N09 (FROM THE
