1. DATA FOR THIS SURVEY WAS GATHERED IN MARCH 2010 & AUGUST 2017 BY RELD TllA'ltRSE UTILIZING ELECTRONIC DATA COU£C110N.

2. EQUIPMENT USED: THEOMAT 00'01.5" EOM: ± 2 PPM, ;I; 3 MM

3. HORIZONTAL DAlUM & BASIS Of COORDINATES: NAO 83\91 WASHINGTON STATE PLANE, NORTH ZONE \IERllCAL OAlUM: NAVO 88

DURING 'lHE MONTH OF MARCH 2011, PACIRC SUR'iE\'lNG & ENGINEERING, INC USED REAL TIME KINEMAllC GPS METHODS TO LOCALIZE ON 6 WASHINGTON STATE DEPARTMENT OF TRANSPORTATION GEODETIC MONUMENTS. THE DATA WAS SIMULTANEOUSLY ADJJSTED AS ONE NETWORK.

WASHINGTON STATE GEOOEllC SER'ilCES MONUMENTS (PIO# 1583, 3555, 7150, 7188, AND 7207} WERE USED TO ESTABLISH HORIZONTAL POSITIONS. THE UNCONSTRAINED CLOSURE OF THE CONTROL POINTS RESULltO IN ERROR ELLIPSES OF LESS THAN 13MM (0.04 FEET). CONVENTIONAL SUR'v£Y TRA'v£RSE AND SIDE- SHOTS l'f£RE ACCOMPLISHED UTILIZING THESE POINTS.

WASHINGTON STATE GEODETIC SERVICES MONUMENTS (PIO# 1583, 3555, 7150, 7188, 7196 AND 7207) WERE USED TO ESTABLISH VERllCAl POSITIONS. THE RMS CLOSURE OF THESE CONTROL POINTS RESULTED IN VERTICAL ERROR EWPSES Of LESS THAN 2(1jM (0.06 ml).

REAL TIME KINEMA nc OBSERVATIONS WERE COllECTED \li1TH ONE TOPCON GR3 RECEIVER AS A BASE STATION AND ONE TOPCON GR3 RECEIVER CONFIGURED AS A ROVER. ALL POINTS WERE OCCUPIED FOR A MINIMUM OF 200 EPOCHS.

CONSTRUCTION NOTES: 1. STABILIZED CONSTRUCTION ENTRANCE (15'X100') TO

BE CONSTRUCTED IN ACCORDANCE WITH WSDOT STD PLAN NO. 1-80.10-02.

I\

EROSION AND SEDIMENT CONTROL NOTES: 1. THE ESC FACILITIES SHO\\N ON THIS PLAN MUST BE CONSTRUCTED PRIOR TO OR IN CONJUNCTION WITH ALL

CLEARING AND GRADING SO AS TO ENSURE THAT THE TRANSPORT OF SEDIMENT TO SURFACE WATER, DRAINAGE SYSTEMS, AND ADJACENT PROPERTIES IS MINIMIZED.

2. THE ESC FACILITIES SHO\\N ON THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR THE ANTiaPATED SITE CONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE ESC FACILITIES SHALL BE UPGRADED AS NEEDED FOR UNEXPECTED STORM EVENTS AND MODIFIED TO ACCOUNT FOR CHANGING SITE CONDITIONS.

3. ALL QEARING, GRUBBING, AND GRADING SHALL BE CONTAINED WITHIN THE LIMITS ESTABLISHED BY THE ENGINEER. ALL VEGETATION OUTSIDE DESIGNATED LIMITS SHALL REMAIN UNDISTURBED.

4. ALL STOCKPILES ARE TO BE LOCATED IN SAFE AREAS AND PROTECTED FROM EROSION BY MECHANICAL OR VEGETATIVE MEANS.

5. ALL EXPOSED AND UNWORKED SOILS SHALL BE STABILIZED BY SEEDING, MULCHING, MATTING, OR PLASTIC COVERING. FROM OCT. 1 TO APRIL 30, NO SOILS SHALL REMAIN UNSTABILIZED FOR MORE THAN 2 DAYS. FROM MAY 1 TO SEPT. 30, NO SOILS SHALL REMAIN UNSTABILIZED FOR MORE THAN 7 DAYS.
