| 2021-11-18 12:46:48 | THIS IS A CONCEPTUAL LEVEL REVIEW. CONSTRUCTION LEVEL |
| | DETAILS, DESIGN CALCULATIONS AND THE POLLUTION |
| | PREVENTION PLAN WILL BE REVIEWED AS PART OF THE |
| | ENGINEERING DEVELOPMENT APPROVAL AND BUILDING PERMIT |
| | APPLICATION PROCESSES. |
| | |
| | THE FOLLOWING COMMENTS MUST BE ADDRESSED PRIOR TO SITE |
| | PLAN APPROVAL: |
| | |
| | 1. SITE IS WITHIN A SPECIAL FLOOD HAZARD AREA (SFHA) |
| | WITH BASE FLOOD ELEVATIONS (BFES) OF 6 FT NAVD AND 7 FT |
| | NAVD. PRELIMINARY COASTAL FLOOD MAPS MAY SHOW HIGHER |
| | BASE FLOOD ELEVATIONS. STRUCTURES WITHIN SFHA SHALL |
| | HAVE MINIMUM 2 FEET OF FREEBOARD ABOVE THE BFE. |
| | |
| | 2. THE CITY?S OFFICIAL VERTICAL DATUM PER CITY CODE IS |
| | NGVD1929. THE CITY IS ALLOWING SURVEYS AND PLANS TO USE |
| | NAVD1988 PROVIDED THE CONVERSION EQUATION BETWEEN |
| | NAVD1988 AND NGVD1929 IS ALSO PROVIDED. THE SURVEY AND |
| | THE CIVIL PLANS USE DIFFERENT CONVERSION FACTORS |
| | BETWEEN THE VERTICAL DATUMS NAVD1988 AND NGVD1929. |
| | |
| | 3. SUGGEST RESERVING SHEET NUMBERS ENDING WITH .00 FOR |
| | OVERALL PLAN VIEWS. |
| | |
| | 4. SHOWING ALL EXISTING WATER, SEWER AND DRAINAGE |
| | SYSTEMS WITHIN THE PARK. THERE IS AN EXISTING FM NEAR |
| | N. FLAGLER DRIVE THAT IS NOT SHOWN. THERE ARE OFFSITE |
| | DRAINAGE SYSTEMS THAT FLOW THROUGH THE PARK. SHOW THE |
| | FORCEMAIN FROM THE LIFT STATION AT THE NORTH END OF THE |
| | PARK. |
| | |
| | 5. EXISTING SANITARY SEWER MAIN IS MISLABELED AS A |
| | FORCE MAIN. |
| | |
| | 6. LABEL THE STREETS ON ALL OF THE PLAN SHEETS. |
| | |
| | 7. PROVIDE INFORMATION FOR N. FLAGLER DRIVE / BUTLER |
| | STREET INTERSECTION. |
| | |
| | 8. C1.XX STORMWATER POLLUTION PREVENTION PLAN SHEETS |
| | A. SHOW FLOATING TURBIDITY BARRIERS AROUND THE OUTFALL |
| | PIPES TO LAKE WORTH LAGOON AND AROUND ANY CONSTRUCTION |
| | WITHIN THE LAKE WORTH LAGOON. |
| | B. SHOW INLET PROTECTION FOR DRAINAGE STRUCTURES ON N. |
| | FLAGLER DRIVE INCLUDING FIRST INLET NORTH OF THE NEW |
| | DRIVEWAY TO 26TH STREET. |
| | |
| | 9. C2.XX DEMOLITION PLAN SHEETS |
| | A. IDENTIFY WHAT IS TO HAPPEN TO THE STORM SEWER |
| | SYSTEMS |
| | B. ADD NOTE TO PLANS THAT THE FORCEMAIN ALONG THE |
| | EXTENSION OF 23RD STREET IS TO REMAIN. |
| | C. ADD NOTE TO PLANS THAT THE LIFT STATION FORCEMAIN |
| | AND THE TWO GRAVITY SEWER SYSTEMS ALONG THE EXTENSION |
| | OF 26TH STREET ARE TO REMAIN. |
| | D. INCLUDE DEMOLITION NOTES, EXISTING CONDITIONS NOTES |
| | AND DEMOLITION SCHEDULE ON ALL SHEETS. |
| | |
| | 5. C5.XX PGD PLAN SHEETS |
| | A. NUMBER DRAINAGE STRUCTURES FOR EASE OF REFERENCE. |
| | B. DRAINAGE SYSTEM TO BE DESIGNED TO MEET SFWMD ERP |
| | REQUIREMENTS. |
| | C. DRAINAGE SYSTEM DESIGN TO CONSIDER SEA LEVEL RISE. |
| | D. HOW WILL ROCK RIPRAP REVETMENT AFFECT EXISTING |
| | DRAINAGE OUTFALLS? |
| | E. REPLACE ENDS OF OUTFALL PIPES WHERE THE SEAWALL IS |
| | BEING REPLACED. NEW PIPE SHOULD EXTEND BEYOND TIE BACK |
| | AREA OF SEAWALL. MANATEE GRATES MAY BE REQUIRED. |
| | F. REPLACE STORM PIPE FROM SEAWALL TO LIMITS OF WHERE |
| | THE PIPE IS REPLACED BY THE 26TH STREET UTILITY AND |
| | ROADWAY PROJECT. |
| | G. CHECK MATCHLINE SHEET REFERENCES. |
| | H. HOW IS THE RUNOFF FROM THE PARKING LOT ON SHEET |
| | C5.01 TREATED/MANAGED? |
| | I. AVOID PUTTING MANHOLES WITHIN PAVED WALKING AREAS. |
| | J. PROVIDE ADDITIONAL HORIZONTAL SEPARATION BETWEEN |
| | PROPOSED STORM AND EXISTING SANITARY SEWER. |
| | K. LABEL ELEVATIONS OF ALL CONTOUR LINES ON EVERY |
| | SHEET. |
| | L. WILL PROPOSED EXFILTRATION TRENCHES ALONG SEAWALL |
| | INTERFERED WITH THE SEAWALL ANCHOR SYSTEM? |
| | M. UTILITY SYMBOLS ON SHEET C5.08 APPEAR TO BE |
| | DUPLICATED AND NOT ALIGNED. FOR EXAMPLE THERE ARE |
| | MULTIPLE MANHOLE SYMBOLS IN OR NEAR THE DRIVEWAY TO |
| | 26TH ST. |
| | N. THE CB SHOWN IN THE DRIVE FOR 26TH STREET DOES NOT |
| | SHOW UP ON THE SURVEY. IS THIS A NEW STRUCTURE? SUGGEST |
| | PUTTING THE STRUCTURE IN A DIFFERENT LOCATION AND |
| | CONNECTING TO PROPOSED DRAINAGE SYSTEM TO THE SOUTH. |
| | O. EXISTING CB OVER EXISTING 60? RCP ON SHEET C5.09 IS |
| | SHOWN AS MANHOLE ON THE SURVEY. NOTE ON THE SHEET |
| | INDICATES CATCH BASIN BY OTHERS. WHO IS ?BY OTHERS?? |
| | SUGGEST LEAVING MANHOLE TOP AND INSTALLING A SEPARATE |
| | CATCH BASIN WITH PRB TO PREVENT FLOATABLES FROM LEAVING |
| | THE SITE. PERHAPS MOVE THE WEIR CONTROL TO THIS |
| | STRUCTURE. |
| | P. SHOW IMPROVEMENTS WITHIN LAKE WORTH LAGOON AND REFER |
| | TO OTHER SHEETS FOR DESIGN INFORMATION. |
| | Q. LABEL THE CYAN SQUIGGLY LINES ON THE SHEETS. |
| | R. PROVIDE CROSS SECTIONS OF EACH DRIVEWAY TO N. |
| | FLAGLER DRIVE. |
| | S. HOW IS THE FITNESS LAWN AREA GRADED. THE CONTOUR |
| | LINES STOP OF THE PERIMETER OF THE LAWN. |
| | T. FIVE FEET OF FILL PROPOSED IN SOME AREAS OVER THE |
| | EXISTING SANITARY SEWER PIPE. WHAT IS THE CONDITION OF |
| | THE SEWER PIPE AND WILL IT NEED TO BE REPLACED/LINED |
| | PRIOR TO CONSTRUCTION? |
| | U. BETHESDA TERRACE IMPROVEMENTS INCLUDED WITH THIS |
| | PROJECT? DRAINAGE STRUCTURES NOT CORRECTLY SHOWN. |
| | V. ADD HERRINGBONE HATCH PATTERN TO LEGEND. |
| | W. CONSIDER LOW IMPACT DEVELOPMENT WATER QUALITY |
| | TREATMENT DESIGN INSTEAD OF OR IN ADDITION TO |
| | EXFILTRATION TRENCHES. |
| | X. INCLUDE CITY DETAILS FOR PRB?S AND DRIVEWAYS. |
| | |
| | 6. SHOW AND LABEL CONTOURS ON THE UTILITY PLAN SHEETS. |
| | |
| | 7. INCORPORATE THE CITY?S 26TH STREET UTILITY AND |
| | ROADWAY IMPROVEMENT PROJECT DESIGN. |
| | |
| | 8. AVOID PLANTING TREES OVER OR NEAR UTILITY LINES AND |
| | EXFILTRATION TRENCHES. |
| | |
| | |
| | THE FOLLOWING COMMENTS MUST BE ADDRESSED PRIOR TO |
| | ISSUANCE OF CONSTRUCTION AUTHORIZATION INCLUDING |
| | BUILDING PERMITS AND ENGINEERING DEVELOPMENT APPROVAL. |
| | |
| | 1. PROVIDE COPY OF SFWMD ERP PERMIT BEFORE START OF |
| | CONSTRUCTION. |
| | |
| | 2. PROVIDE A COPY OF THE DRAINAGE CALCULATIONS WITH THE |
| | ENGINEERING PERMIT APPLICATION. |
