About this file

Written by GovTribe AI · Nov 10, 2025

These are engineering and construction documents for the Butler Springs Park Remediation project, prepared by Davis & Floyd, Inc. for Greenville County Parks, Recreation & Tourism in Greenville, South Carolina. The project involves comprehensive site remediation including demolition of existing asphalt, installation of new storm drainage systems, grading, and erosion control measures. The project documents are dated May 2025, with construction documents issued on 06/11/2025, and include detailed plans for storm drainage profiles, site grading, demolition, and environmental control measures.

The project scope includes removing existing asphalt, installing new storm drainage infrastructure with multiple inline drains (A1-A5) using HDPE pipes ranging from 8" to 15" in diameter, implementing sediment control tubes, and performing site stabilization. Technical specifications outline precise installation requirements, including pipe gradients, tie-ins to existing infrastructure, and detailed erosion control procedures. The plans emphasize environmental protection, with specific notes on sediment tube installation, maintenance protocols, and requirements for permanent site stabilization. The project appears to be funded through local government parks and recreation funds, with a focus on infrastructure improvement and environmental management.

SEDIMENT TUBE INSTALLATION

INSPECTION & MAINTENANCE:

1. THE KEY TO FUNCTIONAL SEDIMENT TUBES IS WEEKLY INSPECTIONS, ROUTINE MAINTENANCE, AND

REGULAR SEDIMENT REMOVAL.

2. REGULAR INSPECTIONS OF SEDIMENT TUBES SHALL BE CONDUCTED ONCE EVERY CALENDAR WEEK AND, AS RECOMMENDED, WITHIN 24-HOURS AFTER EACH RAINFALL EVEN THAT PRODUCES 1/2-INCH OR

MORE OF PRECIPITATION.

3. ATTENTION TO SEDIMENT ACCUMULATIONS IN FRONT OF THE SEDIMENT TUBE IS EXTREMELY

IMPORTANT. ACCUMULATED SEDIMENT SHOULD BE CONTINUALLY MONITORED AND REMOVED WHEN

NECESSARY.

4. REMOVE ACCUMULATED SEDIMENT WHEN IT REACHES 1/3 THE HEIGHT OF THE SEDIMENT TUBE.

5. REMOVED SEDIMENT SHALL BE PLACED IN STOCKPILE STORAGE AREAS OR SPREAD THINLY ACROSS

DISTURBED AREA. STABILIZE THE REMOVED SEDIMENT AFTER IT IS RELOCATED.

6. LARGE DEBRIS, TRASH, AND LEAVES SHOULD BE REMOVED FROM IN FRONT OF TUBES WHEN FOUND.

7. IF EROSION CAUSES THE EDGES TO FALL TO A HEIGHT EQUAL TO OR BELOW THE HEIGHT OF THE SEDIMENT TUBE, REPAIRS SHOULD BE MADE IMMEDIATELY TO PREVENT RUNOFF FROM BYPASSING

TUBE.

8. SEDIMENT TUBES SHOULD BE REMOVED AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN

COMPLETELY STABILIZED. PERMANENT VEGETATION SHOULD REPLACE AREAS FROM WHICH

SEDIMENT TUBES HAVE BEEN REMOVED.

GENERAL NOTES:

1. SEDIMENT TUBES MAY BE INSTALLED ALONG CONTOURS, IN DRAINAGE CONVEYANCE CHANNELS, AND

AROUND INLETS TO HELP PREVENT OFF-SITE DISCHARGE OF SEDIMENT-LADEN STORM WATER

RUNOFF.

2. SEDIMENT TUBES ARE ELONGATED TUBES OF COMPACTED GEOTEXTILES, CURLED EXCELSIOR WOOD, NATURAL COCONUT FIBER, OR HARDWOOD MULCH. STRAW, PINE NEEDLE, AND LEAF MULCH-FILLED

SEDIMENT TUBES ARE NOT PERMITTED.

3. THE OUTER NETTING OF THE SEDIMENT TUBE SHOULD CONSIST OF SEAMLESS, HIGH-DENSITY

POLYETHYLENE PHOTODEGRADABLE MATERIALS TREATED WITH ULTRAVIOLET STABILIZERS OR A

SEAMLESS, HIGH-DENSITY POLYETHYLENE NON-DEGRADABLE MATERIAL.

4. SEDIMENT TUBES, WHEN USED AS CHECKS WITHIN CHANNELS, SHOULD RANGE BETWEEN 18-INCHES AND 24-INCHES DEPENDING ON CHANNEL DIMENSIONS. DIAMETERS OUTSIDE THIS RANGE MAY BE

ALLOWED WHERE NECESSARY WHEN APPROVED.

5. CURLED EXCELSIOR WOOD, OR NATURAL COCONUT PRODUCTS THAT ARE ROLLED UP TO CREATE A

SEDIMENT TUBE ARE NOT ALLOWED.

6. SEDIMENT TUBES SHOULD BE STAKED USING WOODEN STAKES (2-INCH X 2-INCH) OR STEEL POSTS (STANDARD "U" OR "T" SECTIONS WITH A MINIMUM WEIGHT OF 1.25 POUNDS PER FOOT) AT A MINIMUM

OF 48-INCHES IN LENGTH PLACED ON 2-FOOT CENTERS.

7. INSTALL ALL SEDIMENT TUBES TO ENSURE THAT NO GAPS EXIST BETWEEN THE SOIL AND THE BOTTOM

OF THE TUBE. MANUFACTURER'S RECOMMENDATIONS SHOULD ALWAYS BE CONSULTED BEFORE

INSTALLATION.

8. THE ENDS OF ADJACENT SEDIMENT TUBES SHOULD BE OVERLAPPED 6-INCHES TO PREVENT FLOW

AND SEDIMENT FROM PASSING THROUGH THE FIELD JOINT.

9. SEDIMENT TUBES SHOULD NOT BE STACKED ON TOP OF ONE ANOTHER, UNLESS RECOMMENDED BY

MANUFACTURER.

10. EACH SEDIMENT TUBE SHOULD BE INSTALLED IN A TRENCH WITH A DEPTH EQUAL TO 1/5 THE

DIAMETER OF THE SEDIMENT TUBE.

11. SEDIMENT TUBES SHOULD CONTINUE UP THE SIDE SLOPES A MINIMUM OF 1-FOOT ABOVE THE DESIGN

FLOW DEPTH OF THE CHANNEL.

12. INSTALL STAKES AT A DIAGONAL FACING INCOMING RUNOFF.

1. EXTENT OF WORK - PROVIDE SOIL ESTABLISHMENT OF FINISH GRADE, PREPARATION,

FERTILIZING AND SEEDING, OF ALL NEWLY GRADED FINISHED EARTH SURFACES, UNLESS

INDICATED OTHERWISE, AND AT ALL AREAS INSIDE OR OUTSIDE THE LIMITS OF

CONSTRUCTION THAT ARE DISTURBED BY THE CONTRACTOR'S OPERATIONS.

2. TURF ESTABLISHMENT PERIOD - THE ESTABLISHMENT PERIOD FOR TURF SHALL BEGIN

IMMEDIATELY AFTER INSTALLATION, WITH THE APPROVAL OF THE ENGINEER, AND CONTINUE

UNTIL THE DATE THAT THE OWNER ACCEPTS THE PROJECT OR PHASE FOR BENEFICIAL

USE AND OCCUPANCY AND A STAND OF GRASS IS ACHIEVED. DURING THE TURF

ESTABLISHMENT PERIOD THE CONTRACTOR SHALL:

A. WATER THE TURF TO MAINTAIN AN ADEQUATE SUPPLY OF MOISTURE WITHIN

ROOT ZONE. AN ADEQUATE SUPPLY OF MOISTURE IS THE EQUIVALENT OF 1 INCH

OF ABSORBED WATER PER WEEK EITHER THROUGH NATURAL RAINFALL OR

AUGMENTED BY PERIODIC WATERING. APPLY WATER AT A MODERATE RATE SO

AS NOT TO FLOOD THE TURF.

B. PROVIDE THE FOLLOWING TURF ESTABLISHMENT:

1. ERADICATE ALL WEEDS. WATER, FERTILIZE, OVERSEED, AND PERFORM ANY

OTHER OPERATION NECESSARY TO PROMOTE THE GROWTH OF GRASS.

2. RESEED OR RE-SOD AREAS VOID OF TURF ONE SQUARE FOOT AND LARGER IN AREA.

3. MOW THE NEW LAWN AT LEAST THREE TIMES PRIOR TO THE FINAL INSPECTION.

BEGIN MOWING WHEN GRASS IS 4 INCHES HIGH. MOW TO A 2 1/2 INCH HEIGHT.
