NARRATIVE:

THE PURPOSE OF THIS SURVEY IS TO PREPARE A PRE-DESIGN BASE MAP FOR FUTURE

EXPANSION OF MARION COUNTY'S COMMUNICATION SITE 'HOUSE MOUNTAIN,.

JOHN D PUTNAM PERFORMED THE FIELD SURVEY ON OCTOBER 1ST, 2024. TERRESTRIAL

MEASUREMENTS WERE MADE UTILIZING A LEICA MS60 1 SECOND ROBOTIC TOTAL STATION. GNSS

OBSERVATIONS WERE MADE UTILIZING A LEICA GS16 RECEIVER.

BEARINGS ARE BASED ON THE NAD 1983(2011) [EPOCH 2010] OREGON

COORDINATE REFERENCE SYSTEM, SALEM ZONE AS DETERMINED BY GNSS

OBSERVATION TO THE OREGON REAL-TIME GNSS NETWORK.

THE LEASE AREA WAS ESTABLISHED BY HOLDING FOUND MONUMENTS '500' -

'504'.

ALL MEASUREMENTS SHOWN MATCH RECORD UNLESS OTHERWISE NOTED.

FALLINGS SHOWN ARE FROM THE TRUE POINT.

NOTES:

1. FIELD SURVEY AND MAPPING PERFORMED ON OCTOBER 1ST, 2024 BY J. PUTNAM UTILIZING

A LEICA MS60 ROBOTIC TOTAL STATION AND LEICA GS18 GNSS RECEIVERS.

2. UNITS ARE STATED IN INTERNATIONAL FEET.

3. BEARINGS ARE BASED ON THE NAD 1983(2011) [EPOCH 2010] ORGON COORDINATE

PREFERENCE SYSTEM, SALEM ZONE AS DETERMINED BY GNSS OBSERVATION TO THE

OREGON REAL-TIME GNSS NETWORK .

4. ELEVATIONS ARE BASED NAVD 1988 AS ESTABLISHED BY GNSS OBSERVATION TO THE

OREGON REAL-TIME GNSS NETWORK.

5. ALL DISTANCES ARE GRID BASED ON THE LOW DISTORTION ZONE.

6. TRUE GEODETIC AZIMUTH = GRID AZIMUTH (BEARING BASIS) + MAPPING ANGLE. THE

MAPPING ANGLE IS 00°25'24" AT CONTROL STATION 101. THE MAGNETIC DECLINATION FROM

TRUE GEODETIC AZIMUTH IS 14°33 EAST.

7. THE TERM "CERTIFY" (OR ITS DERIVATIVES) SHALL MEAN A STATEMENT SIGNED AND/OR

SEALED BY A SURVEYOR REPRESENTING THAT THE SURVEYOR'S KNOWLEDGE,

INFORMATION AND BELIEF, IN ACCORDANCE WITH COMMONLY ACCEPTED PROCEDURES

CONSISTENT WITH APPLICABLE STANDARDS OF PRACTICE, AND IS NOT A GUARANTY OR

WARRANTY, EITHER EXPRESSED OR IMPLIED.

8. THIS SURVEY SHOWS ONLY THOSE DEDICATIONS AND EASEMENTS CONTAINED IN THE

SUPPLIED TITLE SEARCH. IT IS POSSIBLE THAT OTHER RECORDED OR UNRECORDED

INSTRUMENTS EFFECTING THIS PROPERTY MAY EXIST.

9. ORION GEOMATICS MAKES NO WARRANTIES AS TO MATTERS OF UNWRITTEN TITLE SUCH AS

ADVERSE POSSESSION, ACQUIESCENCE, ESTOPPLE, ETC.

10. ALL STATEMENTS WITHIN THE CERTIFICATION, AND OTHER REFERENCES LOCATED

ELSEWHERE HEREON, RELATED TO: UTILITIES, IMPROVEMENTS, STRUCTURES, BUILDINGS,

PARTY WALLS, EASEMENTS, SERVITUDES, AND ENCROACHMENTS; ARE BASED SOLELY ON

ABOVE GROUND, VISIBLE EVIDENCE, UNLESS ANOTHER SOURCE OF INFORMATION IS

SPECIFICALLY REFERENCED HEREON.

CONSTRUCTION.

4. THE ESC FACILITIES SHOWN ON THIS PLAN MUST BE CONSTRUCTED IN CONJUNCTION WITH ALL CLEARING AND GRADING ACTIVITIES, AND IN SUCH A MANNER AS TO INSURE THAT SEDIMENT AND SEDIMENT LADEN WATER DOES

NOT ENTER THE DRAINAGE SYSTEM, ROADWAYS, OR VIOLATE APPLICABLE WATER STANDARDS.

5. THE ESC FACILITIES SHOWN ON THIS PLAN ARE MINIMUM REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS.

DURING CONSTRUCTION PERIODS, THESE ESC FACILITIES SHALL BE UPGRADED AS NEEDED FOR UNEXPECTED STORM EVENTS AND TO ENSURE THAT SEDIMENT AND SEDIMENT LADEN WATER DOES NOT LEAVE THE SITE.

6. THE ESC FACILITIES SHALL BE INSPECTED DAILY BY THE APPLICANT/CONTRACTOR AND MAINTAINED AS NECESSARY

TO ENSURE THEIR CONTINUED FUNCTIONING.

7. AT NO TIME SHALL SEDIMENT BE ALLOWED TO ACCUMULATE MORE THAN 1/3 THE BARRIER HEIGHT. ALL CATCH BASINS AND CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING. THE CLEANING OPERATIONS SHALL NOT

FLUSH SEDIMENT-LADEN WATER INTO THE DOWNSTREAM SYSTEM.

8. STABILIZED GRAVEL ENTRANCES SHALL BE INSTALLED AT THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OF THE PROJECT. ADDITIONAL MEASURES MAY BE REQUIRED TO INSURE THAT ALL PAVED AREAS

ARE KEPT CLEAN FOR THE DURATION OF THE PROJECT.

9. STORM DRAIN INLETS, BASINS, AND AREA DRAINS SHALL BE PROTECTED UNTIL PAVEMENT SURFACES ARE

COMPLETED AND/OR VEGETATION IS RE-ESTABLISHED.

10. PAVEMENT SURFACES AND VEGETATION ARE TO BE PLACED AS RAPIDLY AS POSSIBLE.

11. SEEDING SHALL BE PERFORMED NO LATER THAN SEPTEMBER 1 FOR EACH PHASE OF CONSTRUCTION.

12. IF THERE ARE EXPOSED SOILS OR SOILS NOT FULLY ESTABLISHED FROM OCTOBER 1ST THROUGH APRIL 30TH, THE

WET WEATHER EROSION PREVENTION MEASURES WILL BE IN EFFECT. SEE THE EROSION PREVENTION AND

SEDIMENT CONTROL PLANNING AND DESIGN MANUAL (CHAPTER 4) FOR REQUIREMENTS.

13. NO EXPOSED, BARE SOILS SHALL REMAIN UNSTABILIZED FOR MORE THAN TWO DAYS DURING THE PERIOD OCTOBER 1 THROUGH APRIL 30 OR FOR MORE THAN SEVEN DAYS DURING THE PERIOD OF MAY 1 THROUGH SEPTEMBER 30.

ALL DISTURBED SOIL SURFACES SHALL BE STABILIZED BY A SUITABLE APPLICATION OF "BEST MANAGEMENT

PRACTICES".

14. WHERE FEASIBLE, NO MORE THAN 500 FEET OF TRENCH SHALL BE OPEN AT ONE TIME. EXCAVATED MATERIAL SHALL BE PLACED ON THE UPHIL SIDE OF TRENCHES PROVIDED IT DOES NOT CONFLICT WITH SAFETY

REQUIREMENTS.

15. THE DEVELOPER SHALL REMOVE ESC MEASURES WHEN VEGETATION IS FULLY ESTABLISHED.
