| | FEBRUARY 13, 2020 REVIEW SUBMITTAL PACKAGE: |
| | |
| | 1. REPLACE CONCRETE INLET TOP OF CATCH BASIN INLET ON |
| | THE NORTH SIDE OF TRINITY PL. WEST OF S. OLIVE AVE. |
| | |
| | 2. ELIMINATE THE BLEEDER IN THE STORMWATER CONTROL |
| | STRUCTURE. |
| | |
| | 3. THE HYDRAULIC GRADE LINE OF THE S. OLIVE AVE |
| | DRAINAGE SYSTEM SHOULD BE CONSIDERED IN THE SETTING OF |
| | THE WEIR ELEVATION FOR THE CONTROL STRUCTURE. IF THE |
| | WEIR IS SET TOO LOW, THERE MAY BE BACKFLOW INTO THE |
| | ONSITE DRAINAGE SYSTEM FROM THE ROADWAY DRAINAGE |
| | SYSTEM. |
| | |
| | 4. EXFILTRATION TRENCH IS PROPOSED WITHIN THE BUILDING. |
| | THE VERTICAL CLEARANCE SHOULD BE DESIGNED FOR |
| | MAINTENANCE VEHICLES (E.G. VACUUM TRUCKS) ACCESS TO THE |
| | MANHOLES AND FOR CONSTRUCTION EQUIPMENT TO REPLACE THE |
| | EXFILTRATION TRENCH WHEN IT IS NO LONGER FUNCTIONING AS |
| | DESIGNED. |
| | |
| | 5. WHY THE BREAK IN THE EXFILTRATION TRENCH ABOUT 65 |
| | FEET NORTH OF THE SOUTH TRENCH DRAIN? |
| | |
| | 6. CONSIDER MOVING THE NORTH TRENCH DRAIN ACROSS THE |
| | DRIVEWAY FURTHER SOUTH, AT A HIGHER RIM ELEVATION. THIS |
| | TRENCH MAY BECOME A BUBBLE UP STRUCTURE AND RELEASE |
| | WATER TOWARD TANGLEWOOD COURT WHEN ALL OFFSITE |
| | DISCHARGE SHOULD BE THROUGH THE CONTROL STRUCTURE. |
| | |
| | 7. CONFIRM DRIVEWAY APRONS IN THE RIGHT OF WAY MEET |
| | CITY STANDARDS. |
| | |
| | 8. LIST THE SEASONAL HIGH GROUNDWATER TABLE ELEVATION |
| | ON THE EXFILTRATION TRENCH DETAIL ST-8. |
| | |
| | 9. LIST THE VERTICAL DATUM AND CONVERSION EQUATION TO |
| | NGVD1929 ON SHEET C4.02 AND ALL SHEETS WITH ELEVATION |
| | INFORMATION. |
| | |
| | 10. LABEL THE STREETS ON THE EROSION AND SEDIMENTATION |
| | CONTROL PLAN SHEET. |
| | |
| | 11. PROVIDE INLET PROTECTION DETAIL FOR AN INLET |
| | WITHOUT A HOOD OPENING. THERE ARE VALLEY GUTTER INLETS |
| | AND DITCH BOTTOM STYLE INLETS WITHIN THE RIGHT-OF-WAY. |
| | |
| | 12. CAN CONSTRUCTION TRAFFIC ACCESS BE LIMITED TO THE |
| | SIDE STREETS AND NOT FROM S. OLIVE AVE.? |
