NOTES:

1. CONTRACTOR SHALL BE RESPONSIBLE FOR VERIFYING ACTUAL DISTANCES AND

SPACING OF COMPONENTS ON THE GROUND.

2. CONTRACTOR SHALL CAST A PIPE SECTION SLEEVE INTO THE CONCRETE WALL OF THE

SAND FILTER FOR THE PIPE PENETRATION, AS SHOWN ON SHEET 4.

3. ALLOW FIVE (5) FEET BETWEEN THE NEAREST POINTS OF ADJACENT SEPTIC TANKS, AND

STEP DOWN

" PER FOOT FROM THE OUTLET OF ONE TANK TO THE INLET OF THE NEXT.

4. AT A MINIMUM, CONTRACTOR SHALL PROVIDE AND INSTALL 780 LINEAR FEET OF PIPING

FOR THE LATERALS: SIX (6) ZONES WITH TWO (2) LATERALS EACH, EACH LATERAL AT

LEAST 65 FEET LONG.

5. ORIFICES IN DRAINFIELD LATERALS SHALL BE

" IN DIAMETER, AND EACH ORIFICE SHALL

BE FITTED WITH AN ORIFICE SHIELD. TO AVOID ERRORS AND INCONSISTENCY, AND TO

UPHOLD WARRANTY TERMS, CONTRACTOR SHALL PROVIDE PRE-MANUFACTURED

DRAINFIELD LATERALS. CONTRACTOR IS NOT PERMITTED TO DRILL THEIR OWN

ORIFICES.

6. PROVIDE LABOR AND MATERIALS NEEDED TO CONNECT THE CAMP HOST WASTEWATER

LINE TO THE NEW SEPTIC SYSTEM.

7. SAWCUT AND REMOVE CONCRETE PATHWAY ALONG THE EAST SIDE OF THE RESTROOM

BUILDING, AS SHOWN IN THE HATCH PATTERN. THE AREA OF THE SIDEWALK TO BE

REMOVED IS APPROXIMATELY 24' LONG BY 3' WIDE. THE EXISTING CONCRETE IS BADLY

DAMAGED AND CREATING A TRIPPING HAZARD. REPLACE THE REMOVED PORTION OF

CONCRETE WITH

"- MINUS CRUSHED AGGREGATE BASE MATERIAL, 6" COMPACTED

DEPTH, WITH GEOTEXTILE FILTER FABRIC UNDERNEATH. SLOPE 2% TO DRAIN.

NOTES:

1. SIEVE ANALYSIS SHALL BE PROVIDED FOR THE FILTER SAND AND UNDERDRAIN MEDIA PROVIDED.

2. LATERAL LINES SHALL BE 1

" IN DIAMETER, AND COMPOSED OF POLYVINYL CHLORIDE WITH A

MINIMUM PRESSURE RATING OF 200 PSI.

3. EXISTING GROUND ELEVATION NOT SHOWN; CONTRACTOR SHALL FIT THE SAND FILTER TO THE

EXISTING TERRAIN. DUE TO THE SAND DUNE ALONG THE WEST EDGE, AND THE OVERALL SLOPE

TO THE EAST, IT IS EXPECTED THAT THE WEST WALL OF THE SAND FILTER WILL BE MOSTLY

BURIED AGAINST THE ADJACENT SAND DUNE, WHILE THE EAST WALL WILL BE MOSTLY EXPOSED.

4. "LOAMY SAND" ABOVE THE FILTER FABRIC SHALL MEET THE REQUIREMENTS OF OAR 340-071-0295, AS DESCRIBED IN SECTION 02530, SANITARY SEWAGE.

5. ALL PVC LATERALS SHALL HAVE AT LEAST 3" OF UNDER DRAIN MEDIA BELOW, AND SUFFICIENT

MEDIA ABOVE TO COVER THE ORIFICE SHIELDS.

6. MAINTAIN AT LEAST 3" OF CONCRETE BETWEEN THE STEEL REINFORCEMENT (REBAR) AND THE

EDGE OF CONCRETE. OVERLAP REBAR AND CONDUCT OTHER CONCRETE FRAMING,

REINFORCEMENT, PLACING, CURING, TESTING, ETC. IN ACCORDANCE WITH AMERICAN CONCRETE

INSTITUTE (ACI) STANDARDS AND SECTION 03300 OF THE PROJECT SPECIFICATIONS.

7. TOP EDGE OF CONCRETE WALL SHALL BE LEVEL ALONG ENTIRE PERIMETER OF THE SAND FILTER.
