IN NARROW CHANNELS, ADJUST ROCK TO FIT STREAMBANKS.

1. THE OUTLETS OF ALL PIPE TO BE INSTALLED AND ALL EXISTING PIPE TO REMAIN SHALL BE CONSTRUCTED OR RECONSTRUCTED TO PROVIDE FOR A MINIMUM OF A-1% DRAINAGE SLOPE AWAY FROM ALL CSP FORA MINIMUM OF 50'. WHERE NECESSARY, CULVERTS SHALL HAVE A LEAD OFF DITCH OF SUFFICIENT LENGTH TO ASSURE AN ADEQUATE DRAINAGE OUTLET. PAYMENT FOR THE CONSTRUCTION OF LEAD OFF DITCHES UP TO 50' HAS

BEEN INCLUDED IN CULVERT PAY ITEMS.

2. CULVERTS NOTED TO BE SKEWED ON THE PLANS SHALL BE SKEWED AS STAKED BY THE ENGINEER.

3. ALL EXISTING PIPE LISTED FOR REMOVAL SHALL BE DISPOSED OFF GOVERNMENT PROPERTY. IN MULTIPLE PIPE INSTALLATIONS, THE ADJACENT

SIDES OF PIPE SHALL BE AT LEAST ONE-HALF THE NOMINAL PIPE DIAMETER APART OR 3', WHICHEVER IS LESS.

4. BACKFILL AROUND CULVERTS IS COMPACTION METHOD B, OF SPECIAL PROJECT SPECIFICATIONS SUB PARAGRAPH 209.11 - "ADJUST THE MOISTURE

CONTENT OF THE BACKFILL MATERIAL TO A MOISTURE CONTENT SUITABLE FOR COMPACTION. COMPACT EACH LAYER USING APPROPRIATE

COMPACTION EQUIPMENT UNTIL VISUAL DISPLACEMENT CEASES."

5. ALL GROUND DISTURBED OUTSIDE OF THE ROADBED IS REQUIRED TO BE SEEDED AND MULCHED, UNLESS NOTED OTHERWISE.

6. PIPE INSTALLATIONS LISTED AS "DEEP FILL" HAVE 5' OR MORE OF COVER AND PAYMENT INCLUDES CONSIDERATION FOR ADDITIONAL EXCAVATION

WORK REQUIRED AT THESE LOCATIONS.

7. POLYMERIC COATED CORRUGATED STEEL PIPE MAY BE SUBSTITUTED FOR ALUMINUM COATED, TYPE 2 CORRUGATED STEEL PIPE AND WILL BE

CONSIDERED AS EQUAL FOR PAYMENT. WHERE POLYMERIC COATED PIPE IS USED, THICKNESS OF COATING SHALL BE 10 MILS INSIDE AND 10 MILS OUTSIDE. POLYMERIC COATED PIPE MAY NOT BE BANDED TO ALUMINUM COATED OR SOLID ALUMINUM PIPE. ALL EXPOSED METAL OR AREAS OF PIPE WHERE POLYMERIC OR ALUMINUM COATING IS DAMAGED SHALL BE PAINTED WITH A ZINC DUST-ZINC OXIDE POWDER CONFORMING TO FEDERAL SPECIFICATION TT-P-641 OR MIL-P-21085 AND A TWO COMPONENT EPOXY PAIN, "SCOTCH CLAD", 2M, PPG OR EQUAL. THIS WORK SHALL BE

CONSIDERED INCIDENTAL TO CULVERT PAY ITEMS.

8. 18" MINIMUM BANDING OR LARGER WILL BE REQUIRED TO ATTACH MULTIPLE SECTIONS OF PIPE 36-INCHES IN DIAMETER OR LARGER.

9. MASTIC SEALANT REQUIRED ON ALL PIPES LARGER THAN 48" REQUIRING BANDING. THE MASTIC SHALL CONFORM TO AASHTO M 243. PIPES

SMALLER THAN 48" SHALL BE SEALED WITH MASTIC IF ANY GAPS BETWEEN PIPES IS GREATER THAN 1.5"
