| 2015-04-08 09:01:23 | YOUR APPLICATION FOR ENGINEERING DEVELOPMENT APPROVAL |
| | WAS RECEIVED ON JANUARY 9, 2015. AS DISCUSSED WITH YOU |
| | ON MARCH 3, 2015, THE FOLLOWING INFORMATION IS REQUIRED |
| | BEFORE WE CAN RECOMMEND APPROVAL OF THE PROJECT. |
| | |
| | #1 VERIFY CONFLICT ELEVATIONS. THE PLAN SHOWS AN 18" |
| | PAVEMENT COVER TO TOP OF 30" DIP FORCEMAIN. THIS |
| | DISTANCE WILL NEED VERIFICATION. PLEASE MAKE PROVISIONS |
| | ON YOU PLANS TO HAVE THE CONTRACTOR VERIFY THIS DEPTH |
| | BEFORE PROJECT COMMENCEMENT. |
| | |
| | #2 PLEASE SHOW DOMESTIC WATER AND FIRE PROTECTION |
| | INDEPENDENT. PUBLIC UTILITY POLICY DICTATES THAT EACH |
| | SHALL COME OFF A SEPARATE SOURCE. DEDICATED FIRELINE |
| | JUST REQUIRED A DETECTOR CHECK ASSEMBLY AT THE SOURCE |
| | OF WATER. DETECTOR CHECK ASSEMBLIES (DCDA) ARE ALSO |
| | CONSIDERED PRIVATE THEREFORE THEY MUST BE AS CLOSE TO |
| | CITY WATER SOURCE AS POSSIBLE BUT JUST INSIDE YOU |
| | PROPERTY LINE AFTER THE CITY?S CONTROL VALVE (RWGV). |
| | VALVE MUST SHOWN IN A UTILITY EASEMENT. |
| | |
| | #3 DOMESTIC WATER METER SIZE IS NOT CALLED OUT. |
| | |
| | #4 FIRE HYDRANTS ON-SITE MUST BE TIED TO PRIVATE |
| | FIRELINE MAIN AND NOT DOMESTIC. |
| | |
| | #5 FIRE DEPARTMENT CONNECTION (FDC) IS NOT SHOWN ON |
| | PLANS. PLEASE SHOW AND DIMENSION FEATURE FROM NEAREST |
| | CITY FIRE HYDRANT. |
| | |
| | #6 WHEN CONNECTING TO EXISTING SANITARY SEWER MANHOLES, |
| | FULL REHABILITATION IS REQUIRED. PLEASE REVISE NOTE TO |
| | SAY THAT YOU WILL REHABILITATE. |
| | |
| | #7 PROVIDE WATER AND SEWER CALCULATIONS - FAC 64-E |
| | 6.008 |
| | |
| | #8 SIDEWALK ALONG GRANT IS NOT CONTINUOUS THRU |
| | RIGHT-OF-WAY. WHERE IT MEANDERS UNTO SITE, THE PRIVATE |
| | SIDEWALK WILL BE OWNED AND MAINTAINED; HOWEVER AN |
| | ACCESS SIDEWALK EASEMENT WILL BE REQUIRED FOR ALL |
| | PEDESTRIANS. |

| | |
| | STORM WATER COMMENTS: |
| | |
| | THANK YOU FOR SUBMITTAL FOR ENGINEERING DEVELOPMENT |
| | APPROVAL FROM THE CITY OF WEST PALM BEACH, PUBLIC WORKS |
| | DEPARTMENT. THE FOLLOWING ITEMS NEED TO BE ADDRESSED |
| | BEFORE WE CAN ISSUE THE APPROVAL FOR THE PROJECT. |
| | |
| | 1. REVISE THE PLANS TO INDICATE WHICH PORTIONS OF THE |
| | POTABLE WATER, SANITARY SEWER, AND STORMWATER SYSTEM |
| | WILL REMAIN PUBLICALLY OWNED AND WHICH SECTIONS WILL BE |
| | MAINTAINED BY THE APPLICANT. TYPICALLY, THE CITY'S |
| | OWNERSHIP STOPS AT THE RIGHT-OF-WAY LINE UNLESS |
| | EXTENUATING CIRCUMSTANCES REQUIRED THE OWNERSHIP |
| | DIVISION TO TAKE PLACE AT ANOTHER LOCATION. |
| | |
| | 2. SUBMIT DEMAND, FLOW, AND YARDAGE CALCULATIONS FOR |
| | THE POTABLE WATER, SANITARY SEWER, AND SOLID WASTE |
| | COLLECTION. |
| | |
| | 3. SUBMIT A HYDRAULIC ANALYSIS OF THE PROPOSED WATER |
| | DISTRIBUTION SYSTEM. |
| | |
| | 4. THE SUBMITTED SURVEY REFERENCE NAVD 88. SECTION 78-9 |
| | OF THE CITY'S CODE OF ORDINANCES SPECIFIES NGVD 1929 AS |
| | THE OFFICIAL CITY VERTICAL DATUM. PLEASE REVISE THE |
| | PLANS TO REFERENCE NGVD 1929. |
| | |
| | 5. REVISE THE PLANS TO INCLUDE THE UPDATED TRENCH |
| | RESTORATION DETAIL (P-4) ON SHEET DT-5. |
| | |
| | 6. VERIFY THAT THE PROPOSED SIZE AND QUANTITY OF TRASH |
| | BINS IS APPROPRIATE FOR THE WASTE YARDAGE ANTICIPATED |
| | TO BE GENERATED BY THE COMPLEX. CONSIDER USING A |
| | COMPACTOR TO REDUCE THE YARDAGE OF WASTE THAT WILL NEED |
| | TO BE COLLECTED. |
| | |
| | 7. PLEASE SHOW THE LOCATIONS OF THE ROOF DRAINS, HOW |
| | THEY WILL CONNECT INTO THE STORMWATER SYSTEM, AND |
| | PROVIDE CALCULATIONS SHOWING BOTH THE VOLUME AND |
| | VELOCITY OF THE ROOF DISCHARGE HAS BEEN TAKEN INTO |
| | ACCOUNT AS PART OF THE DESIGN. IF THE ROOF DRAINS WILL |
| | TIE INTO THE SYSTEM UPSTREAM OF THE EXFILTRATION TRENCH |
| | WEIRS, PLEASE ENSURE THAT THE WEIR HEIGHT WAS USED AS |
| | THE TAILWATER ELEVATION FOR THE ROOF DRAINAGE SYSTEM. |
| | |
| | 8. THE PROJECT MUST PROVIDE ADEQUATE STORMWATER |
| | MANAGEMENT, INCLUDING NOT MODIFYING THE VELOCITY OR |
| | VOLUME OF OFF-SITE STORMWATER DISCHARGE. DESCRIBE HOW |
| | THIS WILL BE ACHIEVED. COMPLIANCE WITH CHAPTER 40E-4 |
| | FAC WILL DEMONSTRATE COMPLIANCE WITH THIS PROVISION. |
| | [CODE OF ORDINANCES SECTIONS 90-201, 94-35(C )(11), |
| | 94-307, AND 94-580] THE SUBMITTED CALCULATIONS DO NOT |
| | SHOW THE HISTORIC OFF-SITE DISCHARGE RATE OR THE |
| | PROPOSED DISCHARGE RATE. |
| | |
| | 9. REVISE THE DRAINAGE CALCULATIONS TO UTILIZE THE |
| | HISTORIC (WITH BUILDINGS) CONDITION OF THE SITE AS THE |
| | EXISTING CONDITIONS. |
| | |
| | 10. SHOW THAT THE PEAK STAGE RESULTING FROM THE 25 |
| | YEAR, 3 DAY STORM EVENT IS RETAINED ON SITE AS SHOWN IN |
| | THE SUBMITTED STORMWATER MODEL. |
| | |
| | 11. PLEASE PROVIDE DOCUMENTATION FOR THE TAILWATER |
| | ELEVATION USED IN THE SUBMITTED STORMWATER |
| | CALCULATIONS. THE CALCULATIONS UTILIZE BOTH 19 FT NGVD |
| | AND 16.8 FT NGVD. |
| | |
| | 12. THE STARTING STORAGE VALUES FOR THE EXISTING |
| | LANDSCAPE AREA (22.8 FT) APPEARS TO BE LOWER THAN THE |
| | ELEVATIONS SHOWN ON THE SURVEY. THE STARTING STORAGE |
| | ELEVATION FOR THE PROPOSED SIDEWALKS (23.75) AND |
| | STARTING ELEVATION FOR LANDSCAPE AREAS (22.8) ALSO |
| | APPEARS TO BE LOWER THAN THE ELEVATIONS SHOWN ON THE |
| | PROPOSED PLANS. THE STAGE-STORAGE ALSO TAKES CREDIT FOR |
| | BOTH THE VOLUME IN THE TRENCH AND PIPE AS WELL AS THE |
| | VOLUME CALCULATED THROUGH THE EXFILTRATION TENCH |
| | FORMULA. THE VOLUME OF THE TRENCH AND PIPE ARE TAKEN |
| | INTO CONSIDERATION IN THE EXFILTRATION TRENCH FORMULA. |
| | THE ASSUMED VOID SPACE OF 50% IS HIGH FOR THE |
| | EXFILTRATION ROCK. PLEASE REVISE THE CALCULATIONS TO |
| | REFLECT THE SUBMITTED DESIGN. |
| | |
| | 13. WHAT IS THE CONDITION OF THE PROPOSED DRAINAGE |
| | OUTFALL STRUCTURE. THE STRUCTURE MAY NEED TO BE |
| | REHABILITATED OR REPLACE IN ORDER TO ACCOMMODATE THE |
| | PROPOSED PIPE AND DISCHARGE VELOCITY. |
| | |
| | 14. PLEASE REVISE THE DRIVEWAY APRONS TO MEET THE |
| | CITY'S ENGINEERING DESIGN STANDARDS. PLEASE ALSO |
| | INCLUDE THE DETAILS FOR THE SIDEWALK RAMPS, HTTP://WPB. |
| | ORG/ENGINEERING/ENGINEERING-SERVICES/ENGINEERING-STANDA |
| | RDS/ |
| | |
| | ADVISORY: A RIGHT-OF-WAY PERMIT FROM THE ENGINEERING |
| | DEPARTMENT WILL BE REQUIRED FOR ALL WORK WITHIN THE |
| | CITY OF WEST PALM BEACH RIGHT-OF-WAY WHICH WILL RESULT |
| | IN A CLOSURE OF EITHER A TRAVEL LAND OR SIDEWALK. THE |
| | APPLICATION FORM AND CONSTRUCTION STANDARDS CAN BE |
| | FOUND AT |
