2. VERTICAL CONTROL: ELEVATIONS ARE BASED ON NGVD 29.BENCHMARKS AND/OR STRUCTURE ELEVATIONS FROM EXISTINGSURVEYS OR REFERENCE DRAWINGS MAY RESULT IN VARIANCESWITH ELEVATIONS INDICATED ON THE DRAWINGS FOR EXISTINGFACILITIES.
3. HORIZONTAL AND VERTICAL CONTROL ESTABLISHED ASSHOWN ON C102. THE PROJECTED 100 YEAR FLOOD ELEVATION IS 131.0 ANDTHE PROJECTED 500 YEAR FLOOD ELEVATION IS 132.3, PER WASHINGTONCOUNTY FLOOD INSURANCE STUDY, NOVEMBER 2016.
4. EXISTING UTILITIES AND STRUCTURES (UNDERGROUND, SURFACE, OROVERHEAD) ARE INDICATED ONLY TO THE EXTENT THAT SUCH INFORMATIONWAS KNOWN, OR MADE AVAILABLE TO, OR DISCOVERED BY THE ENGINEERIN PREPARING THE DRAWINGS. THE LOCATIONS, CONFIGURATIONS, ANDELEVATIONS OF SUBSURFACE FACILITIES AND UTILITIES ARE APPROXIMATE,AND NOT ALL UTILITIES AND FACILITIES MAY BE INDICATED. OVERHEADUTILITIES ARE NOT INDICATED IN ARCHITECTURAL ELEVATIONS, PROFILEOR SECTION DRAWINGS. THE ENGINEERING INVESTIGATIONS, LOCATION,AND DESIGNATION OF SUBSURFACE UTILITIES INDICATED IN THESE CONTRACTDOCUMENTS HAS BEEN PERFORMED TO QUALITY LEVEL C IN ACCORDANCE WITHGENERALLY ACCEPTED ENGINEERING PRINCIPLES AND PRACTICES AS OUTLINEDIN ASCE STANDARD AND GUIDELINE BULLETIN CI/ASCE 38-02 UNLESSOTHERWISE DESIGNATED. WHERE SUCH ACTIVITIES HAVE BEEN TO A HIGHERLEVEL OF QUALITY, THE HIGHER QUALITY LEVEL FOR THE AFFECTED AREASIS INDICATED IN THE CONTRACT DOCUMENTS.

MINIMUM PIPECOVER SHALL BE FROM THE EXISTING, PROPOSED, OR FUTURE GROUND SURFACEOR ROAD PROFILE, WHICHEVER GROUND SURFACE OR ROAD PROFILE IS APPLICABLE AS INDICATED ON THE DRAWINGS. IF THE PROPOSED GROUND SURFACE IS ABOVE THE EXISTING GROUND SURFACE INDICATED ON THE DRAWINGS AND IS NOT THE ACTUAL GROUND SURFACE AT THE TIME OF PIPELINE
INSTALLATION, INSTALL THE PIPELINE TO PROVIDE MINIMUM PIPE COVER FROM THEACTUAL GROUND SURFACE IF ACCEPTABLE TO THE ENGINEER. HIGH POINTS IN THEPIPELINE WILL NOT BE PERMITTED EXCEPT AT LOCATIONS OF AIR VALVES AS INDICATED ON THE DRAWINGS. REVIEW THE PIPELINE PROFILE REQUIREMENTS WITHTHE ENGINEER PRIOR TO PREPARING LAYING SCHEDULES AND PERFORMING FIELDSTAKING.
