| | SURFACE DRAINAGE SHALL BE DIVERTED TO A STORM SEWER |
| | CONVEYANCE OR OTHER APPROVED POINT OF COLLECTION THAT |
| | DOES NOT CREATE A HAZARD. LOTS SHALL BE GRADED TO DRAIN |
| | SURFACE WATER AWAY FROM FOUNDATION WALLS. THE GRADE |
| | SHALL FALL A MINIMUM OF 6 INCHES (152 MM) WITHIN THE |

| | PROJECTION EXCEPT FOR GABLE END RAKES OR ON A ROOF |
| | ABOVE ANOTHER ROOF. |
| | |
| | 5) THE PLANS DO NOT SPECIFY ANY REINFORCEMENT IN THE 4" |
| | CONCRETE FLOOR SLAB. DUE TO THE SOIL CONDITIONS, IT IS |

| | 8) PROVIDE STRUCTURAL DETAILS FOR THE LEDGERS THAT ARE |
| | SUPPORTING THE ROOF TRUSSES. |
| | |
| | 9) PROVIDE THE ROOF UPLIFT VALUES FOR A 10 SQFT |
| | EFFECTIVE WIND AREA. |
| | |
| | 10) IN THE TABLE ON SHEET S.3 THE ROOF UPLIFT VALUES |
| | FOR ZONES 2 AND 3 ARE IDENTICAL. THE PARAPET IS |
| | REQUIRED TO BE 3 FEET HIGH AROUND THE ENTIRE PERIMETER |
| | OF THE ROOF IN ORDER FOR THE ZONE 2 (PERIMETER) |
| | PRESSURES TO BE THE SAME AS THE ZONE 3 (CORNER) |
| | PRESSURES. ACSE 7 - 10. |
| | |
| | 11) PROVIDE SCUPPER SIZING CALCULATIONS. FBC 107.2.1 & |
| | FBC- PLUMBING 1106.7 |

| | 12) R903.4.1 OVERFLOW DRAINS AND SCUPPERS. WHEN OTHER |
| | MEANS OF DRAINAGE OF OVERFLOW WATER IS NOT PROVIDED, |
| | OVERFLOW SCUPPERS SHALL BE PLACED IN WALLS OR PARAPETS |
| | NOT LESS THAN 2 INCHES (51 MM) NOR MORE THAN 4 INCHES |
| | (102 MM) ABOVE THE FINISHED ROOF COVERING AND SHALL BE |
| | LOCATED AS CLOSE AS PRACTICAL TO REQUIRED VERTICAL |
| | LEADERS OR DOWNSPOUTS OR WALL AND PARAPET SCUPPERS. AN |
| | OVERFLOW SCUPPER SHALL BE SIZED IN ACCORDANCE WITH THE |
| | FLORIDA BUILDING CODE, PLUMBING. |
| | |
| | 13) THE PLANS SHOW LOUVERED WALL ATTIC VENTS ON SHEET |
| | A.2 AND THE ENERGY FORM SPECIFIES AN UNVENTED ATTIC. |
| | PLEASE CLARIFY FBC 107.2.1 |
| | |
| | 14) IF THE ATTIC IS VENTED PROVIDE THE NET FREE AREA OF |
| | THE VENTS AND THE CALCULATIONS FOR MINIMUM VENT AREA |
| | PER FBC - R806.2 |
| | |
| | 15) IF THIS IS AN UNVENTED ATTIC SHOW THAT IT COMPLIES |
| | WITH FBC-R806.5 UNVENTED ATTIC AND UNVENTED ENCLOSED |
| | RAFTER ASSEMBLIES. UNVENTED ATTIC ASSEMBLIES (SPACES |
| | BETWEEN THE CEILING JOISTS OF THE TOP STORY AND THE |
| | ROOF RAFTERS) AND UNVENTED ENCLOSED RAFTER ASSEMBLIES |
| | (SPACES BETWEEN CEILINGS THAT ARE APPLIED DIRECTLY TO |
| | THE UNDERSIDE OF ROOF FRAMING MEMBERS/RAFTERS AND THE |
| | STRUCTURAL ROOF SHEATHING AT THE TOP OF THE ROOF |
| | FRAMING MEMBERS/RAFTERS) SHALL BE PERMITTED IF ALL THE |
| | FOLLOWING CONDITIONS ARE MET: |
| | |
| | 1. THE UNVENTED ATTIC SPACE IS COMPLETELY CONTAINED |
| | WITHIN THE BUILDING THERMAL ENVELOPE. |
| | |
| | 2. NO INTERIOR CLASS I VAPOR RETARDERS ARE INSTALLED ON |

| | THE FLORIDA BUILDING CODE, ENERGY CONSERVATION, ANY |
| | AIRIMPERMEABLE INSULATION SHALL BE A CLASS II VAPOR |

| | AIR-IMPERMEABLE INSULATION SHALL BE APPLIED IN DIRECT |
| | CONTACT WITH THE UNDERSIDE OF THE STRUCTURAL ROOF |
| | SHEATHING AS SPECIFIED IN TABLE R806.5 FOR CONDENSATION |
| | CONTROL. THE AIR-PERMEABLE INSULATION SHALL BE |
| | INSTALLED DIRECTLY UNDER THE AIR-IMPERMEABLE |
| | INSULATION. |
| | |
| | 5.4. WHERE PREFORMED INSULATION BOARD IS USED AS THE |
| | AIR-IMPERMEABLE INSULATION LAYER, IT SHALL BE SEALED AT |
