HomeMy Public PortalAboutVILLAGE PL_10AB DRAIN.pdfEROSION AND SEDIMENT NARRATIVE NOTES:
1, DESCRIPTION: THE PARCEL IDENTIFIED BELOW IS LOCATED IN CHATHAM COUNTY, GEORGIA AND IS CURRENTLY UNDEVELOPED AND ZONED
C-2. THE DEVELOPERS INTENT IS TO CONSTRUCT A TWO -UNIT RESIDENCE WITH AN ASSOCIATED DRIVEWAY. ADJACENT AREAS ARE ZONED
C-2, AND ARE EITHER UNDEVELOPED OR DEVELOPED AS RE5IDENCE5, NO IMPACTS ARE EXPECTED TO THESE ADJACENT AREAS,
2. TOPOGRAPHIC AND DRAINAGE INFORMATION: CONTOURS, BUILDINGS, ROADWAY, PROPERTY LINES ETC. TAKEN FROM SURVEY PERFORMED
BY EMC ENGINEERING SERVICES, INC. THE EXISTING DRAINAGE PATTERN CONSISTS OF OVERLAND FLOW FROM THE EAST SIDE OF THE
PROPERTY TO THE WEST AND FLOWS INTO A NEARBY WETLAND AREA. THE WETLAND AREA DISCHARGES INTO HORSE PEN CREEK WHICH
EVENTUALLY DISCHARGES INTO THE ATLANTIC OCEAN.
3, VEGETATION: THE VEGETATION ON THE PROPERTY CONSISTS PRIMARILY OF GRASSES. ANY SUITABLE TOP SOIL WILL BE STOCKPILED ON
SITE AND LATER SPREAD IN PROPOSED VEGETATIVE AREAS.
4. BUFFER REQUIREMENTS: EXCEPT AS PROVIDED IN PART IV.(III) OF THE GENERAL NPDES PERMIT NO. GAR 100001 NON-EXEMPT ACTIVITIES
SHALL NOT BE CONDUCTED WITHIN THE 25 OR 50 -FOOT UNDISTURBED STREAM BUFFERS AS MEASURED FROM THE POINT OF WRESTED
VEGETATION OR WITHIN 25 -FEET OF THE COASTAL MARSHLAND BUFFER AS MEASURED FROM THE JURISDICTIONAL DETERMINATION LINE
WITHOUT FIRST ACQUIRING THE NECESSARY VARIANCES AND PERMITS.
5. EROSION CONTROL PROGRAM: CLEARING WILL BE KEPT TO A MINIMUM. VEGETATION AND MULCH WILL BE APPLIED TO APPLICABLE AREAS
IMMEDIATELY AFTER DEMOLITION AND GRADING IS COMPLETED. LAND -DISTURBING WILL BE SCHEDULED TO LIMIT EXPOSURE OF BARE SOILS
TO EROSION ELEMENTS.
6. SEDIMENT CONTROL PROGRAM: SEDIMENT CONTROL WILL BE ACCOMPLISHED BY THE INSTALLATION OF SEDIMENT BARRIERS, SEDIMENT
TRAP(S), SEDIMENT BASIN(S), AND CHECK DAM(S) WHERE APPLICABLE TO PREVENT SEDIMENT FROM LEAVING THE SITE AND ENTERING THE
STORMWATER DRAINAGE SYSTEM. A CONSTRUCTION ENTRANCE WILL BE UTILIZED TO PREVENT SEDIMENT TRANSPORT VIA VEHICLE
TRACKING ONTO PUBLIC ROADS.
7, STANDARDS AND SPECIFICATIONS: ALL DESIGNS WILL CONFORM TO AND ALL WORK WILL BE PERFORMED IN ACCORDANCE WITH THE
STANDARDS AND SPECIFICATIONS OF THE PUBLICATION ENTITLED, "MANUAL FOR EROSION AND SEDIMENT CONTROL IN GEORGIA".
8. SAFETY PROTECTION: CONSTRUCTION ACTIVITIES WILL BE PERFORMED IN COMPLIANCE WITH ALL APPLICABLE LAWS, RULES AND
REGULATIONS.
9. INSPECTION & MAINTENANCE PROGRAM: EROSION CONTROL MEASURES WILL BE INSPECTED DAILY. ANY DAMAGES OBSERVED WILL BE
REPAIRED BY DAYS END. CLEAN OUT OF SEDIMENT CONTROL STRUCTURES WILL BE PERFORMED IN ACCORDANCE WITH THE
SPECIFICATIONS AND SEDIMENT DISPOSAL ACCOMPLISHED BY ON SITE SPREADING. BARRIERS WILL REMAIN IN PLACE UNTIL SEDIMENT
CONTRIBUTING AREAS ARE STABILIZED. SILT FENCES AND BARRIERS WILL THEN BE REMOVED AND THE AREAS OCCUPIED BY THESE
STRUCTURES WILL BE VEGETATED.
10. PETROLEUM STORAGE, SPILLS AND LEAKS: THE PLANS PROVIDED HEREIN DO NOT ANTICIPATE THE STORAGE OF PETROLEUM PRODUCTS
ON-SITE. THESE PLANS EXPRESSLY DELEGATE THE RESPONSIBILITY OF ON-SITE HAZARDOUS MATERIAL MANAGEMENT TO THE CONTRACTOR.
THE CONTRACTOR SHALL NOT PARK, REFUEL, OR MAINTAIN EQUIPMENT WITHIN STREAM BUFFERS. IF THE CONTRACTOR ELECTS TO STORE
PETROLEUM PRODUCTS ON SITE, THE CONTRACTOR SHALL PREPARE AN ESPCP ADDENDUM THAT ADDRESSES THE ADDITIONAL BMPS
NEEDED FOR ON-SITE STORAGE AND SPILL PREVENTION FOR PETROLEUM PRODUCTS. THIS PLAN SHALL BE PREPARED BY A CERTIFIED
DESIGN PROFESSIONAL AS REQUIRED BY GAR 100001 FOR INCLUSION WITH THESE PLANS.
11_ WASTE MATERIALS, INCLUDING BUILDING MATERIALS, SHALL NOT BE DISCHARGED TO WATERS OF THE STATE, EXCEPT AS AUTHORIZED BY A
SECTION 404 PERMIT.
12. UPON REVIEW OF FIRM, COMMUNITY NO. 135164, BY F.E.M.A. DATED JUNE 17, 1986, IT IS MY OPINION THAT NO PORTION OF THIS PROPERTY
LIES WITHIN A FLOOD HAZARD ZONE.
13_ ACCORDING TO NWI MAPS THERE ARE NO WETLANDS ON SITE_
14. THERE ARE NO BUFFERED STATE WATERS PRESENT WITHIN 20V OF THE PROJECT SITE, A DOUBLE ROW OF TYPE SENSITIVE SILT FENCE
WILL BE UTILIZED TO PROTECT ENVIRONMENTALLY SENSITIVE AREAS.
15. THE PROJECTS RECEIVING WATERS ARE A TRIBUTARY OF HORSE PEN CREEK.
16. ACCORDING TO "SOIL SURVEY OF COLUMBIA COUNTY, GEORGIA", THE EXISTING SOILS TYPES ARE AS FOLLOWS:
• Cuc: CHIPLEY-URBAN LAND COMPLEX 0 TO 5 PERCENT SLOPES
• On OSIER FINE SAND 0 TO 2 PERCENT SLOPES
