| | 10/14/2021 SUBMITTAL: |
| | |
| | |
| | 1. [SATISFIED] ON THE OVERALL SITE PLAN (SHEET 1 OF 2), |
| | SHOULD THE LABEL 'EGRET LAKE ELEMENTARY' ABOVE STA22+00 |
| | BE MOVED TO ABOVE STA41+00? |
| | |
| | 2. [NOT SATISFIED] EVERY SHEET WITH ELEVATION |
| | INFORMATION WILL NEED THE VERTICAL DATUM LISTED ALONG |
| | WITH THE CONVERSION EQUATION TO NGVD1929. {PREVIOUS |
| | COMMENT: 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. LABEL |
| | THE VERTICAL DATUM AND CONVERSION EQUATION TO NGVD1929 |
| | ON ALL CIVIL ENGINEERING SHEETS WITH ELEVATION |
| | INFORMATION.} |
| | |
| | 3. [SATISFIED] FOR SECTION A-A ON SHEET 3 OF 7, |
| | CONSIDER CHANGING THE NOTE 'ALL SLOPES GREATER THAN 5:1 |
| | TO BE SODDED' TO 'ALL SLOPES FLATTER THAN 5:1 TO BE |
| | SODDED' (OR STEEPER DEPENDING ON THE INTENT OF THE |
| | NOTE). |
| | |
| | 4. [SATISFIED FOR NOW. DRAINAGE CALCULATIONS WILL BE |
| | REVIEWED WITH THE ENGINEERING PERMIT SUBMITTAL.] THE |
| | BOTTOM ELEVATION OF THE ROADSIDE SWALES VARY BETWEEN |
| | 13.5 AND 15.8 ALONG THE ROAD. WAS THIS VARIATION |
| | CONSIDERED IN THE SWALE STORAGE VOLUME FOR WATER |
| | QUALITY TREATMENT? WILL THERE BE DITCH BLOCKS |
| | CONSTRUCTED TO MAXIMIZE THE STORAGE IN THE SWALE? THE |
| | DRAINAGE CALCULATIONS WILL BE REVIEWED AT ENGINEERING |
| | PERMIT SUBMITTAL. |
| | |
| | 5. [PARTIALLY SATISFIED] REVIEW THE DISCHARGE LOCATION |
| | FOR THE SWALES EAST OF THE EXISTING FENCE/GATE CROSSING |
| | THE R/W AT APPROXIMATE STA39+00. THERE ARE PRIVATE |
| | PARCELS (SOME DEVELOPED) ADJACENT TO THE R/W. {PREVIOUS |
| | COMMENT: HOW AND WHERE WILL THE ROADSIDE SWALES |
| | DISCHARGE? THERE APPEARS TO BE A BERM ALONG THE NORTH |
| | SIDE OF THE EXISTING DITCH EAST OF STA11+00. WILL THE |
| | TOP OF THE BERM BE AFFECTED WITH THE ROAD |
| | CONSTRUCTION?} |
| | |
| | 6. [SATISFIED - THIS PIPE IS THE RESPONSIBILTY OF THE |
| | SCHOOL DISTRICT.] PROVIDE CONDITION ASSESSMENT OF THE |
| | STORM PIPE(S) CROSSED BY THE PROPOSED ROAD (APPROX. |
| | STA39+00). |
| | |
| | 7. [PARTIALLY SATISFIED] WEIR ELEVATION OF NEW CONTROL |
| | STRUCTURE (IN THE DETENTION AREA) IS 19.50 FEET NAVD. |
| | THE DIMENSIONS IN THE EXFILTRATION TRENCH DETAIL WILL |
| | PROVIDE TOP OF TRENCH ELEVATIONS BETWEEN 19.70 FEET |
| | NAVD AND 20.10 FT NAVD, WHICH IS HIGHER THAN THE WEIR |
| | ELEVATION AND THE EXFILTRATION TRENCH WILL NOT BE FULLY |
| | SURCHARGED. {PREVIOUS COMMENT: CHECK THE ELEVATIONS |
| | LISTED FOR THE FRENCH DRAIN DETAIL ON SHEET 3 OF 7 AND |
| | THE DRAINAGE CONTROL STRUCTURE DSC-1 DETAIL ON SHEET 4 |
| | OF 7.} |
| | |
| | 8. [SATISFIED - MAY WANT TO CONSIDER CRUSHED CONCRETE |
| | AS ROAD BASE MATERIAL IN ADDITION TO SOIL CEMENT] |
| | LIMEROCK MAY NOT BE SUITABLE FOR THE ROAD BASE IF IT |
| | WILL BE SUSCEPTIBLE TO SATURATION FROM THE HIGH GROUND |
| | WATER TABLE AND/OR SWALE STORAGE. |
| | |
| | NEW COMMENTS (THESE MAYBE ADDRESSED DURING ENGINEERING |
| | PERMIT SUBMITTAL); |
| | 9. CONSIDER PLACING GEOTEXTILE (SOILED FILLED CELLS, |
| | ETC.) ACROSS THE WEIR AND THE OUTSIDE SLOPE OF THE |
| | DETENTION AREA TO PROTECT AGAINST EROSION. |
| | |
| | 10. NOTE 3 ON SHEET 1 OF 2 FOR THE SEWER LIFT STATION |
| | LISTS THE SEASONAL HIGH WATER TABLE ELEVATION AS 0.0' |
| | NAVD. |
| | |
| | 11. SHEET 1 OF 7 (FENCE FILL AND GRADE PLAN SHEET) |
| | LISTS THE FFE ELEVATION OF THE RELAY VAULT AS 22.17 FT |
| | NAVD. THE SECTION THRU SEPTIC TANK SYSTEM DETAIL ON |
| | SHEET 1 OF 2 (WATER LINE CONNECTION AND SEWER LIFT |
| | STATION DETAILS SHEET) CALLS OUT MIN. 1% SLOPE FOR THE |
| | 4" LATERAL. |
| | |
| | 12. SHEET 1 OF 7 (FENCE FILL AND GRADE PLAN SHEET) |
| | CALLS OUT MIN. 2% SLOPE (1/4 INCH PER FOOT) FOR THE |
| | 4-INCH SEWER LATERAL.. THE SECTION THRU SEPTIC TANK |
| | SYSTEM DETAIL ON SHEET 1 OF 2 (WATER LINE CONNECTION |
| | AND SEWER LIFT STATION DETAILS SHEET) CALLS OUT THE |
| | FINISHED LFOOR ELEVATION OF 21.70 FT NAVD FOR THE |
| | SUBSTATION RELAY VAULT. |
