| 2021-07-07 15:07:21 | THE FOLLOWING COMMENTS ARE FROM THE REVIEW OF THE |
| | 6/18/2021 SUBMITTAL. ONLY COMMENT #2 CAN POSSIBLY |
| | AFFECT THE SITE PLAN. |
| | |
| | 1. [NOT SATISFIED] THIS COMMENT CAN BE ADDRESSED DURING |
| | ENGINEERING PERMIT SUBMITTAL. SFWMD APPEARS TO HAVE |
| | STOMRWATER AS-BUILT DRAWINGS ON ITS WEBSITE FOR THE ERP |
| | PERMIT FOR EXECUTIVE CENTER DRIVE. PREVIOUS COMMENT: ON |
| | THE DRAINAGE PLAN, PROVIDE PIPE SIZES AND PIPE MATERIAL |
| | FOR EXISTING STORM PIPES, SEWER MAINS, FORCE MAINS AND |
| | WATER MAINS. {ADDITIONAL COMMENT: NOT ALL EXISTING |
| | UTILITIES ARE LABELED INCLUDING WITHIN THE EXECUTIVE |
| | CENTER DRIVE R/W.] |
| | |
| | 2. [NOT SATISFIED] THIS CAN BE ADDRESSED DURING |
| | ENGINEERING PERMIT SUBMITTAL PROVIDED THE SOLUTION DOES |
| | NOT AFFECT THE STORMWATER DETENION AREAS. THIS COMMENT |
| | WAS DISCUSSED WITH THE EOR. HE WILL MODIFY THE END |
| | TREATMENT OF THE PIPE AT THE SOUTH END OF THE SOUTH |
| | STORMWATER DETENTION AREA, LIKELY WITH A MITERED END |
| | SECTION. THE PROPOSED GRATE ELEVATION (13.00) OF THE |
| | CONFLICT STRUCTURE IS SHOWN TO BE LOWER THAN THE |
| | INTERMEDIATE CONTOIUR ELEVATION (13.5 FEET) OVER THE |
| | SANITARY SEWER PIPE AT THE NORTH END OF THE NORTH |
| | DETENTION AREA. NOTE(S) SHOULD BE ADDED TO THE PLANS TO |
| | RESTRICT HEAVY EQUIPMEINT OVER UTILITY PIPES WITH |
| | INSUFFICIENT COVER DEPTH TO PROTECT THE PIPES FROM THE |
| | WEIGHT OF THE EQUIPEMENT. PREVIOUS COMMENT: CHECK PIPE |
| | COVER FOR PIPES WITHIN THE PROPOSED DRY DETENTION |
| | AREAS. [ADDITIONAL COMMENTS: FOR EXAMPLE, THE SANITARY |
| | SEWER PIPE LEAVING PROPOSED SEWER MANHOLE NUMBER 1 WILL |
| | HAVE A TOP OF PIPE ELEVATION AROUND 12.4 FT NAVD AND |
| | THE CONFLICT MANHOLE TO THE EAST WILL BE CONVERTED TO A |
| | CATCH BASIN WITH PROPOSED GRATE ELEVATION OF 13.00 FT |
| | NAVD WITHIN THE PROPOSED DETENTION AREA. FOR ANOTHER |
| | EXAMPLE, THE PROPOSED BOTTOM ELEVATION OF THE DETENTION |
| | AREA IS 10.50 FT NAVD. THE EXISTING CATCH BASIN TO THE |
| | SOUTHWEST OF THE G-G SECTION LABEL ON SHEET C402.0 WILL |
| | BE MODIFIED TO HAVE A GRATE ELEVATION OF 12.50 FT NAVD. |
| | THE INVERT ELEVATION OF THE SOUTH PIPE IS 9.41 FT NAVD. |
| | ASSUMING THE PIPE IS 12 INCHES IN DIAMETER, THE TOP OF |
| | PIPE ELEVATION WILL BE 10.5?+/- NAVD, THE SAME |
| | ELEVATION AS THE BOTTOM OF THE PROPOSED DETENTION |
| | AREA.] |
| | |
| | 3. [SATISFIED] REVIEW GRATE ELEVATION OF 14.80 FT NAVD |
| | FOR CATCH BASIN LOCATED IN NORTH DRIVEWAY. DRIVEWAY |
| | CROSS SLOPE WOULD BE AROUND 3.5% AND LONGITUDINAL SLOPE |
| | AROUND 2%. CONSIDER FLUME INTO THE DRY DETENTION AREA |
| | INSTEAD OF THIS CATCH BASIN. SHEET C401.0 LISTS THE RIM |
| | ELEVATION AS 14.80 FT NAVD AND SHEET C402.0 PROVIDES A |
| | PROPOSED SPOT GRADE OF 15.05 FT NAVD AT THE CATCH |
| | BASIN. |
| | |
| | 4. [SATISFIED] THE STORM PIPE FROM BEST BUY IS SHOWN AS |
| | A SANITARY PIPE AND MAY NOT BE SHOWN IN THE CORRECT |
| | LOCATION. THE PIPE FROM THE SOUTHEAST CORNER OF BEST |
| | BUY IS LIKELY IN THE 12 FT DRAINAGE EASEMENT AND EITHER |
| | CONNECTS TO THE MANHOLE IN THE DRIVEWAY OR CONTINUES |
| | EAST TO THE DITCH ON THE OTHER SIDE OF EXECUTIVE CENTER |
| | DRIVE. PLEASE VERIFY. |
| | |
| | 5. [SATISFIED] THE STORM PIPE FROM THE CENTER OF |
| | EXECUTIVE CENTER DRIVE CONNECTS TO THE MANHOLE IN THE |
| | NORTH DRIVEWAY INSTEAD OF THE OFFSITE CATCH BASIN. |
| | |
| | 6. [SATISFIED] PLEASE EXPLAIN THE PURPOSE OF THE WEIR |
| | IN THE PROPOSED CONTROL STRUCTURE IF THE ELEVATED CATCH |
| | BASINS IN THE PROPOSED DETENTION AREA ARE DESIGNED TO |
| | PROVIDE THE PRE-TREATMENT STORAGE VOLUME. ALSO EXPLAIN |
| | HOW THE DETENTION AREAS WILL PROVIDE TREATMENT WITH AN |
| | PVC LINER. |
| | |
| | 7. [SATISFIED] PROVIDE CROSS SECTION OF ROAD WIDENING |
| | (RIGHT TURN LANE). [ADDITIONAL COMMENT: PROVIDE RANGE |
| | OF PAVEMENT CROSS SLOPE ON THE CROSS SECTION.] |
| | |
| | 8. [SATISFIED] PROVIDE SPOT GRADES FOR NEW RIGHT TURN |
| | LANE AND AT DRIVEWAYS. {ADDITIONAL COMMENT: PROV IDE |
| | ADDITIONAL GRADING FOR SIDEWALK AND DRIVEWAY APRON TO |
| | SHOW HOW BACK OF SIDEWALK ELEVATION OF 15.85 FT NAVD AT |
| | THE DRIVEWAY WILL CONNECT TO THE EXISTING EP ELEVATION |
| | OF 14.12 FT NAVD IN THE STREET.] |
| | |
| | |
| | 9. [SATISFIED] DRY DETENTION AREA IS NOT DEPICTED ON |
| | THE WATER MAIN PROFILE OR FORCE MAIN PROFILE ON SHEET |
| | C503.0. |
| | |
| | 10. [SATISFIED] 6? WATER MAIN TO THE FIRE HYDRANT |
| | LABELED AS 10? WATER MAIN ON THE FORCE MAIN PROFILE. |
| | |
| | 11. [SATISFIED] PROVIDE VERTICAL DATUM CONVERSION |
| | EQUATION ON THE SURVEY. [ADDITIONAL COMMENT: NAVD TO |
| | NGVD CONVERSION IS LISTED AS +1.555 FEET ON THE SURVEY |
| | AND +1.532 FEET ON THE CIVIL ENGINEERING PLANS.] |
| | ADDITIONAL COMMENTS: |
| | 12. PROVIDE INLET PROTECTION FOR ALL CATCH BASINS AND |
| | INLETS ON EXECUTIVE CENTER DRIVE ALONG THE FRONTAGE OF |
| | THE PROJECT AND IMMEDIATELY NORTH AND SOUTH OF THE |
| | PROJECT. [CAN BE ADDRESSED DURING ENGINEERING PERMIT |
| | SUBMITTAL] |
| | |
| | 13. [SATISFIED] SILT FENCE WILL BE NEEDED ALONG THE |
| | WEST PROPERTY LINE. [CAN BE ADDRESSED DURING |
| | ENGINEERING PERMIT SUBMITTAL] |
| | |
| | 14. [NOT SATISFIED] CAN BE ADDRESSED DURING ENGINEERING |
| | PERMIT SUBMITTAL. ENGINEER SHOULD PROVIDE PRE- AND |
| | POST- SPREAD CALCULAITONS AT THE CURB LINE DOWNSTREAM |
| | OF THE RIGHT TURN LANES/DRIVEWAYS. ADDITIONAL CATCH |
| | BASIN(S) MAY BE NEEDED WITHIN THE RIGHT TURN LANE |
| | WIDENING. PREVIOUS COMMENT: CHECK THE CHANGE IN SPREAD |
| | OF RUNOFF AT THE SOUTH END OF THE PROPOSED RIGHT TURN |
| | LANE AT THE PT OF THE CURB AND GUTTER (I.E. AT THE EDGE |
| | OF TRAVEL LANE SOUTH OF THE DRIVEWAY). [CAN BE |
| | ADDRESSED DURING ENGINEERING PERMIT SUBMITTAL). |
