| | COMMENT FROM PREVIOUS LIST: |
| | |
| | 1. PLEASE SEE FEMA GUIDELINES, ATTACHED, FOR MECHANICAL |
| | EQUIPMENT. PLEASE SHOW HOW EQUIPMENT WITH COMPLY WITH |
| | CITY OF WEST PALM BEACH MUNICIPAL CODE REQUIREMENTS FOR |
| | IMPROVEMENTS IN A FLOOD ZONE. 94-541-6. |
| | |
| | 2ND REVIEW, NOT ADDRESSED. NO INFORMATION REGARDING |
| | DUCTWORK WAS PROVIDED. I HAVE HIGHLIGHTED PERTINENT |
| | PORTIONS, SPECIFICALLY: |
| | |
| | SECTION 3.1.2, COMPONENT PROTECTION REFERS TO THE |
| | IMPLEMENTATION OF DESIGN TECHNIQUES THAT PROTECT A |
| | COMPONENT LOCATED BELOW THE DFE FROM FLOOD DAMAGE BY |
| | PREVENTING FLOODWATER FROM ENTERING OR ACCUMULATING |
| | WITHIN THE SYSTEM COMPONENTS. |
| | |
| | SECTION 3.1.3 STATES THAT HVAC EQUIPMENT IS NOT |
| | "DESIGNED TO WITHSTAND INUNDATION BY FLOODWATER" OR |
| | "THE DYNAMIC FORCES OF HIGH VELOCITY FLOW." |
| | |
| | SECTION 3.1.5 STATES "SUPPORTING DISTRUBUTION SYSTEMS |
| | INCLUDE AIR DUCTS . . . ." IT ALSO STATES THAT THE |
| | "NFIP REQUIERS THAT AIR DUCTS IN HVAC SYSTEMS BE |
| | DESIGNED AND/OR LOCATED IN STRUCTURES IN SUCH A WAY THA |
| | TPREVENTS WATER FROM ENTERING OR ACCUMULATING WITH THE |
| | HVAC SYSTEM COMPONENTS DURING BASE FLOODING |
| | CONDITIONS." IT GOES ON TO SAY "LOCATING DUCTWORK BELOW |
| | THE DFE IS NOT PERMITTED UNLESS IT IS DESIGNED AND |
| | CONSTRUCTED SO THAT FLOODWATER WILL NOT ENTER OR |
| | ACCUMULATE WITHIN THE SYSTEM COMPONENTS." THE FOLLOWING |
| | PARAGRAPH STATES THAT THE NFIP DOES NOT RECOMMEND |
| | LOCATING DUCT WORK BELOW THE DFE IN ANY NEW STRUCTURE, |
| | BUT DOES GIVE GUIDELINES IF DUCT WORK MUST BE INSTALLED |
| | BELOW THE DFE. IT ALSO STATES THAT THERE IS NO KNOWN |
| | COST-EFFECTIVE TECHNIQUE FOR DESIGNING AIR DUCTS TO |
| | KEEP FLOODWATER FROM ENTERING OR ACCUMULATING WITHIN |
| | THE SYSTEM COMPONENTS DURING INUNDATION BY FLOODWATERS. |
| | IF DUCTWORK IS INSTALLED BELOW DFE, "THE MATERIAL USED |
| | FOR THE DUCTS MUST BE IPERMEABLE AND WATERTIGHT (SUCH |
| | AS WELDED SEAMLESS DUCTWORK OR LARGE DIAMETER PVC |
| | PIPE)." |
| | |
| | SEE THE NOTE ON THE SIDE OF PAGE 3.1-14, STATES THAT |
| | THE GUIDELINES ARE FOR DUCT SEGMENTS WHICH ARE |
| | WATERTIGHT AND WHICH TERMINATE ABOVE THE DFE. DUCT |
| | SEGMENTS WITH OPENINGS BELOW THE DFE OR THAT TERMINATE |
| | BELOW THE DFE ARE NOT PERMITTED UNDER THE NFIP. |
| | |
| | THE PLAN PROVIDED PROPOSES TO INSTALL THE UNIT AT 13'6" |
| | AND THE DUCTWORK 6" "ABOVE EARTH." THE PROPOSED |
| | ELEVATION FOR DUCTWORK MUST BE GIVEN IN RELATION TO |
| | DFE. WILL THE DUCT BE BELOW DFE? PLEASE SEE THE NOTE |
| | WHICH STATES THAT THIS IS NOT PERMITTED. |
| | |
| | PLEASE SEE THE ENTIRE DOCUMENT FOR MORE INFORMATION |
| | REGARDING INSTALLATION OF HVAC EQUIPMENT. IF SEGMENTS |
| | OF THE DUCTWORK ARE PROPOSED BELOW DFE, PROVIDE ENOUGH |
| | INFORMATION (SPEC SHEETS, CALCULATIONS, ETC.) TO SHOW |
| | THAT THEY MEET THE REQUIREMENTS TO RESIST WATER AND |
| | DYNAMIC FORCES. IF SEGMENTS ARE PROPOSED BELOW DFE, |
| | PROVIDE A SECTION SHOWING DUCTWORK AND ELEVATION AT |
| | EACH POINT, AS WELL AS TERMINATION ELEVATION. |
