| | STOP. |
| | FDOT DETAIL 17346 SHOULD NOT BE SHOWN AS IT CONFLICTS |
| | WITH CITY OF WPB STANDARD. |
| | |
| | #2 SHOW WATER METER LOCATION AND BACKFLOW LOCATION. |
| | WHAT SIZE IS THE CURRENT METER AND BACKFLOW. |
| | |
| | #3 PROVIDE VERTICAL CLEANRANCE BETWEEN WATER AND STORM. |
| | STATE MINIMUM CLEARANCE. |
| | |
| | #4 PARKING 16' IN LENGTH IS CONSIDERED COMPACT? PARKING |
| | MUST BE DESIGNATED AS SUCH VIA SIGN. |
| | |
| | #5 SRUVEY ELEVATIONS IS USING NGVD 1988 DATUM VS NGVD |
| | 1929. |
| | |
| | #6 PROVIDE LOCATION OF SEWER CLEAN-OUT. IF ONE IS NOT |
| | PRESENT PLEASE INDICATE A PROPOSED ONE ON THE PLAN. |
| | |
| | #7 DRIVEWAY APRONS DO NOT REFLECT CONCRETE |
| | CONSTRUCTION. CONTACT FDOT FOR DRIVEWAY APRON |
| | SPECIFICATIONS AND PERMITTING. |
| | |
| | #8 BACKFLOW DETAIL IS MISSING |
| | |
| | #9 PLANS SHOW TWO SHEEL STOPS DETAILS C-5 AND C-10, |
| | ALSO ADA DETEACTABLE RAMP DETAILS ARE SHOWN TWICE C-5 |
| | AND C-9. |
| | |
| | #10 LOCATION FOR BOLLARDS ARE NOT SHOWN. BOLLARDS NEED |
| | REFLECTIVE TYPE TAPE AND IT IS RECOMMENDED THAT THEY BE |

| | STORM WATER / SITE |
| | |
| | S&S 3/4/2013) AND DRAINAGE CALCULATIONS (DATED |
| | 2/25/2013): |
| | DRAINAGE CALCULATIONS: |
| | 1. SURFACE WATER MANAGEMENT ELEMENTS PAGE - |
| | STAGE-STORAGE DESCRIPTIONS LIST ELEVATIONS AS NAVD. THE |
| | ELEVATION VERTICAL DATUM NEEDS TO REFERENCE NGVD 1929. |
| | |
| | 2. PEAK STAGES LISTED FOR THE 3-DAY STORM EVENTS DO NOT |
| | MATCH THE MODELING RESULTS. |
| | |
| | 3. EXFILTRATION TRENCH CALCULATIONS |
| | A. H2 SHOULD EQUAL 7.9 FEET (= MIN. GRATE ELEV. MINUS |
| | BOTTOM OF TRENCH ELEVATION) NOT 9 FEET. |
| | B. TRENCH VOLUME PROVIDED IN 100 LF OF TRENCH (9.17 |
| | AC-IN) INCORRECTLY CONVERTED TO AC-FT (5.96 AC-FT). |
| | |
| | 4. HYDROLOGIC/HYDRAULIC MODELING |
| | A. VERIFY STAGE-STORAGE PER COMMENT 3.B ABOVE. |
| | B. FOR 25-YEAR AND 100-YEAR 3-DAY MODELS, THE TOTAL |
| | RAINFALL AT HOUR 72 IS CONSIDERABLY LESS THAN THE |
| | RAINFALL SHOWN ON THE ISOHYETAL RAINFALL MAPS. |
| | |
| | PLANS: |
| | 1. CAN THE EXFILTRATION TRENCH BE BETWEEN STRUCTURES 1 |
| | AND 2 INSTEAD OF BETWEEN STRUCTURES 2 AND 2? CURRENT |
| | LOCATION OF TRENCH IS NEXT TO LANDSCAPE BUFFER |
| | CONTAINING TREES. |
| | |
| | 2. EXISTING GUMBO LIMBO TREE MAY BE IMPACTED BY THE |
| | CONSTRUCTION OF THE EXFILTRATION TRENCH ALONG THE NORTH |
| | SIDE OF THE SITE. |
| | |
| | 3. THERE APPEARS TO BE A 2:1 SLOPE FOR THE LANDSCAPE |
| | BUFFER NORTH OF THE NORTHEAST DRAINAGE STRUCTURE. |
