Home My WebLink About20220765 Ver 1_Glenville-Stream Buffer Plan_20220810NOTES 1. THIS LOT CONTAINS 5.76 ACRES, MORE OR LESS. 2. THIS LOT IS NOT ZONED. 3. BOUNDARY AND TOPOGRAPHIC INFORMATION PROVIDED BY MCABEE & ASSOCIATES, P.A., FAIRVIEW, NORTH CAROLINA. CONSTRUCTION SCHEDULE & NOTES FOR WORK IN STREAM BUFFERS 1. DISTURBANCE IN STREAM BUFFERS SHALL BE KEPT TO A MINIMUM, AND SHALL ONLY TAKE PLACE IN CONJUNCTION WITH THE CULVERT AND DRIVEWAY INSTALLATION AND ASSOCIATED GRADING. 2. INSTALL DIVERSION AROUND IN —STREAM WORK AREA ACCORDING TO PLAN AND DETAILS ON THIS SHEET, LINING THE BOTTOM AND SIDES WITH FILTER FABRIC AND TOPPING WITH ROCK RIPRAP. 3. ONCE WORK HAS STARTED IN THE STREAM BUFFER AREA, EVERY EFFORT SHALL BE MADE TO COMPLETE WORK AS SOON AS POSSIBLE IN THIS AREA BEFORE MOVING ON TO WORK ON OTHER AREAS OF THE SITE, THUS MINIMIZING THE DURATION OF CONSTRUCTION IN THE BUFFER AREA. 4. CLEAR AREA NEEDED FOR INSTALLATION OF CULVERT. 5. INSTALL CULVERT AND END TREATMENTS. 6. GRADE BUFFER AREAS TO THEIR DESIGN ELEVATIONS. 7. TEMPORARY STABILIZATION WITH SEED AND STRAW AND/OR ROLLED EROSION CONTROL BLANKET SHALL BE INSTALLED ON ALL DISTURBED AREAS AS SOON AS PRACTICAL, AND SHALL REMAIN IN PLACE UNTIL PERMANENT STABILIZATION CAN BE INSTALLED. 8. REMOVE DIVERSION. 9. INSTALL PERMANENT STABILIZATION ACCORDING TO LANDSCAPE PLAN (SHEET 9) AS SOON AS PRACTICAL. EX. GRADE TEMP. SEED & STRAW OR ROLLED EROSION CONTROL BLANKET FILTER FABRIC LINER TOPPED WITH ROCK RIPRAP TO BE USED ON BOTTOM & SIDES OF DIVERSION d50 = 8 IN., CLASS 1 THICKNESS = 18 INCHES FILTER FABRIC LINER TO BE INSTALLED UNDER ROCK RIPRAP FILTER FABRIC: PLACE THE FILTER FABRIC DIRECTLY ON THE GRADED SURFACE OF THE DIVERSION. OVERLAP THE EDGES BY AT LEAST 12 INCHES. BURY THE UPSTREAM END OF THE FABRIC A MINIMUM OF 12 INCHES BELOW GROUND. TAKE CARE NOT TO DAMAGE THE FABRIC WHEN PLACING RIPRAP. IF DAMAGE OCCURS, REMOVE THE RIPRAP, AND REPAIR THE SHEET BY ADDING ANOTHER LAYER OF FABRIC WITH A MINIMUM OVERLAP OF 12 INCHES AROUND THE DAMAGED AREA. IF EXTENSIVE DAMAGE IS SUSPECTED, REMOVE AND REPLACE THE ENTIRE SHEET. ROCK PLACEMENT: PLACEMENT OF RIPRAP SHOULD FOLLOW IMMEDIATELY AFTER PLACEMENT OF FILTER FABRIC. PLACE RIPRAP SO THAT IT FORMS A DENSE, WELL -GRADED MASS OF STONE WITH A MINIMUM OF VOIDS. PLACE RIPRAP TO ITS FULL THICKNESS IN ONE OPERATION.

IN —CHANNEL WORK SHOULD BE AVOIDED BETWEEN OCTOBER 15 AND APRIL 15 TO MINIMIZE IMPACTS TO TROUT REPRODUCTION. 2. IN —CHANNEL WORK SHOULD BE ACCOMPLISHED AS QUICKLY AS POSSIBLE AND VIGILANCE USED IN SEDIMENT AND EROSION CONTROL DURING SITE PREP, CONSTRUCTION, AND CLEAN UP. DISTURBED AREAS SHOULD BE SEEDED, MULCHED AND/OR MATTED AS SOON AS POSSIBLE, PREFERABLY AT THE END OF EACH WORK DAY. A NATIVE RIPARIAN SEED MIX AND NATIVE SHRUBS AND TREES SHOULD BE USED TO PERMANENTLY STABILIZE DISTURBED STREAM AREAS. 3. ANY EROSION CONTROL MATTING USED SHOULD BE FREE OF PLASTIC OR NYLON MESH, AS THIS TYPE OF MESH FREQUENTLY ENTANGLES WILDLIFE AND IS SLOW TO DEGRADE, RESULTING IN A HAZARD THAT MAY LAST FOR YEARS. 4. NON —IMPACTED WETLANDS SHOULD BE CLEARLY DEMARCATED AND FENCED SO THAT HEAVY MACHINERY DOES NOT ACCESS THESE AREAS. 5. RESTORING A NATIVE RIPARIAN BUFFER IS RECOMMENDED ALONG AREAS OF THE STREAM THAT ARE ALREADY CLEARED. A WIDE FORESTED BUFFER CAN ENSURE GREATER BANK STABILITY, FILTER OVERLAND POLLUTANTS, AND PROVIDE HABITAT FOR BIRDS AND OTHER WILDLIFE. \ \•\ • \, • • i > •1 / / •7 �— / i // /\ / \ / / / 1/ / / / / / / �I / / / I / /` / / / •\ / \ / I I 1 /I I\\\\ l ll II//'/ // /III Il \ \ \\\-`- _ / \ / / / /// //////1/ / c/ ( N \/ ; --> -7-77V7 VV,VZ/ V \ / / /\//// // // / ` / /// /,/ / / \ \ \ ////// \ \ / / / //// // \\\ \ // \ \ \// l )ii // /// //l/ \ \ \ \ \/ \ \ // // ( \ \ \\ \\///////\\\\ \\ ////////\ \ \\ \ `,, I I \\\\�� I \\ \ Ra\\ I \ w'1% \ l ( \ I I I I I I I 1 1 1 I 11111111111 \ A I IIII/� (1/0II/ i 1'III/ � I1111111/ ll //) / 11 /1lI I II ll / / I/ IIII/ II / / l /IIII / 1 / l /// / / / / / /IIII / / 7 / / // / I/ OH/ /// / // / / / / / / l/ 1 / l l / / / / / iIlIllllll//llIllI,�Il/ �/ /// / //// // \) / \ \ \ \ \ \ \ \ \ \ I I \ I i 1 II I II I I I I I \ GRADED\ DIVERSION\ \ • \ \\ n C SANDAAG RIP—IAP D / / \ \ \ PLAN VIEW 1"=20' \ \\ \ \ \ \\\ \ \\ \ IJ \\ \\\ \\ \ I.
