TEMPORARY SEEDING SPECIFICATIONS

QUICK REFERENCE FOR ALL REGIONS

SEED

FERTILIZER & LIME

TABLE 3.32-D

(REVISED JUNE 2003)

PERMANENT SEEDING SPECIFICATIONS FOR ALL PIEDMONT AREA

SEED

1. PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT

FINAL GRADE BUT WILL REMAIN DORMANT FOR LONGER THAN 14 DAYS. PERMANENT

STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE

YEAR.

2. DURING CONSTRUCTION OF THE PROJECT, SOIL STOCK PILES AND BORROW AREAS SHALL BE STABILIZED OR PROTECTED WITH SEDIMENT TRAPPING MEASURES. THE APPLICANT IS RESPONSIBLE FOR THE TEMPORARY PROTECTION AND PERMANENT STABILIZATION OF ALL SOIL STOCKPILES ON SITE AS WELL AS BORROW AREAS AND SOIL INTENTIONALLY TRANSPORTED FROM THE PROJECT SITE.

3. A PERMANENT VEGETATIVE COVER SHALL BE ESTABLISHED ON DENUDED AREAS NOT OTHERWISE

PERMANENTLY STABILIZED. PERMANENT VEGETATION SHALL NOT BE CONSIDERED ESTABLISHED

UNTIL A GROUND COVER IS ACHIEVED THAT IS UNIFORM, MATURE ENOUGH TO SURVIVE AND WILL

INHIBIT EROSION.

4. SEDIMENT BASINS AND TRAPS, PERIMETER DIKES, SEDIMENT BARRIERS AND OTHER MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP IN ANY LAND-DISTURBING ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE.

5. STABILIZATION MEASURES SHALL BE APPLIED TO EARTHEN STRUCTURES SUCH AS DAMS, DIKES AND

DIVERSIONS IMMEDIATELY AFTER INSTALLATION.

6. SEDIMENT TRAPS AND SEDIMENT BASINS SHALL BE DESIGNED AND CONSTRUCTED BASED UPON THE

TOTAL DRAINAGE AREA TO BE SERVED BY THE TRAP OR BASIN.

a. THE MINIMUM STORAGE CAPACITY OF A SEDIMENT TRAP SHALL BE 134 CUBIC YARDS PER ACRE OF

DRAINAGE AREA AND THE TRAP SHALL ONLY CONTROL DRAINAGE AREAS LESS THAN THREE

ACRES.

b. SURFACE RUNOFF FROM DISTURBED AREAS THAT IS COMPRISED OF FLOW FROM DRAINAGE AREAS GREATER THAN OR EQUAL TO THREE ACRES SHALL BE CONTROLLED BY A SEDIMENT BASIN. THE MINIMUM STORAGE CAPACITY OF A SEDIMENT BASIN SHALL BE 134 CUBIC YARDS PER ACRE OF

DRAINAGE AREA. THE OUTFALL SYSTEM SHALL, AT A MINIMUM, MAINTAIN THE STRUCTURAL

INTEGRITY OF THE BASIN DURING A 25-YEAR STORM OF 24-HOUR DURATION. RUNOFF

COEFFICIENTS USED IN RUNOFF CALCULATIONS SHALL CORRESPOND TO A BARE EARTH

CONDITION OR THOSE CONDITIONS EXPECTED TO EXIST WHILE THE SEDIMENT BASIN IS UTILIZED.

7. CUT AND FILL SLOPES SHALL BE DESIGNED AND CONSTRUCTED IN A MANNER THAT WILL MINIMIZE

EROSION. SLOPES THAT ARE FOUND TO BE ERODING EXCESSIVELY WITHIN ONE YEAR OF

PERMANENT STABILIZATION SHALL BE PROVIDED WITH ADDITIONAL SLOPE STABILIZING MEASURES

UNTIL THE PROBLEM IS CORRECTED.

8. CONCENTRATED RUNOFF SHALL NOT FLOW DOWN CUT OR FILL SLOPES UNLESS CONTAINED

WITHIN AN ADEQUATE TEMPORARY OR PERMANENT CHANNEL, FLUME OR SLOPE DRAIN

STRUCTURE.

9. WHENEVER WATER SEEPS FROM A SLOPE FACE, ADEQUATE DRAINAGE OR OTHER PROTECTION

SHALL BE PROVIDED.

10. ALL STORM SEWER INLETS THAT ARE MADE OPERABLE DURING CONSTRUCTION SHALL BE

PROTECTED SO THAT SEDIMENT-LADEN WATER CANNOT ENTER THE CONVEYANCE SYSTEM

WITHOUT FIRST BEING FILTERED OR OTHERWISE TREATED TO REMOVE SEDIMENT.

11. BEFORE NEWLY CONSTRUCTED STORMWATER CONVEYANCE CHANNELS OR PIPES ARE MADE

OPERATIONAL, ADEQUATE OUTLET PROTECTION AND ANY REQUIRED TEMPORARY OR PERMANENT

CHANNEL LINING SHALL BE INSTALLED IN BOTH THE CONVEYANCE CHANNEL AND RECEIVING

CHANNEL.

12. WHEN WORK IN A LIVE WATERCOURSE IS PERFORMED, PRECAUTIONS SHALL BE TAKEN TO MINIMIZE

ENCROACHMENT, CONTROL SEDIMENT TRANSPORT AND STABILIZE THE WORK AREA TO THE

GREATEST EXTENT POSSIBLE DURING CONSTRUCTION. NONERODIBLE MATERIAL SHALL BE USED FOR

THE CONSTRUCTION OF CAUSEWAYS AND COFFERDAMS. EARTHEN FILL MAY BE USED FOR THESE

STRUCTURES IF ARMORED BY NONERODIBLE COVER MATERIALS.

13. WHEN A LIVE WATERCOURSE MUST BE CROSSED BY CONSTRUCTION VEHICLES MORE THAN TWICE

IN ANY SIX-MONTH PERIOD, A TEMPORARY VEHICULAR STREAM CROSSING CONSTRUCTED OF

NONERODIBLE MATERIAL SHALL BE PROVIDED.

14. ALL APPLICABLE FEDERAL, STATE AND LOCAL REQUIREMENTS PERTAINING TO WORKING IN OR

CROSSING LIVE WATERCOURSES SHALL BE MET.

15. THE BED AND BANKS OF A WATERCOURSE SHALL BE STABILIZED IMMEDIATELY AFTER WORK IN THE

WATERCOURSE IS COMPLETED.

16. UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THE FOLLOWING

STANDARDS IN ADDITION TO OTHER APPLICABLE CRITERIA:

a. NO MORE THAN 500 LINEAR FEET OF TRENCH MAY BE OPENED AT ONE TIME.

b. EXCAVATED MATERIAL SHALL BE PLACED ON THE UPHILL SIDE OF TRENCHES.

c. EFFLUENT FROM DEWATERING OPERATIONS SHALL BE FILTERED OR PASSED THROUGH AN

APPROVED SEDIMENT TRAPPING DEVICE, OR BOTH, AND DISCHARGED IN A MANNER THAT DOES

NOT ADVERSELY AFFECT FLOWING STREAMS OR OFF-SITE PROPERTY.

d. MATERIAL USED FOR BACKFILLING TRENCHES SHALL BE PROPERLY COMPACTED IN ORDER TO

MINIMIZE EROSION AND PROMOTE STABILIZATION.

e. RESTABILIZATION SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THIS CHAPTER.

f. APPLICABLE SAFETY REQUIREMENTS SHALL BE COMPLIED WITH.

17. WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED OR PUBLIC ROADS,

PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PAVED OR PUBLIC ROAD

SURFACE, THE ROAD SURFACE SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY.

SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND

TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED

ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER. THIS PROVISION SHALL APPLY TO INDIVIDUAL

DEVELOPMENT LOTS AS WELL AS TO LARGER LAND-DISTURBING ACTIVITIES.

18. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE VESCP AUTHORITY. TRAPPED SEDIMENT AND THE DISTURBED SOIL AREAS RESULTING FROM THE DISPOSITION OF TEMPORARY MEASURES SHALL BE

PERMANENTLY STABILIZED TO PREVENT FURTHER EROSION AND SEDIMENTATION.

19. PROPERTIES AND WATERWAYS DOWNSTREAM FROM DEVELOPMENT SITES SHALL BE PROTECTED FROM SEDIMENT DEPOSITION, EROSION AND DAMAGE DUE TO INCREASES IN VOLUME, VELOCITY AND PEAK FLOW RATE OF STORMWATER RUNOFF FOR THE STATED FREQUENCY STORM OF 24-HOUR

DURATION IN ACCORDANCE WITH THE FOLLOWING STANDARDS AND CRITERIA. STREAM

RESTORATION AND RELOCATION PROJECTS THAT INCORPORATE NATURAL CHANNEL DESIGN

CONCEPTS ARE NOT MAN-MADE CHANNELS AND SHALL BE EXEMPT FROM ANY FLOW RATE

CAPACITY AND VELOCITY REQUIREMENTS FOR NATURAL OR MAN-MADE CHANNELS:

a. CONCENTRATED STORMWATER RUNOFF LEAVING A DEVELOPMENT SITE SHALL BE DISCHARGED

DIRECTLY INTO AN ADEQUATE NATURAL OR MAN-MADE RECEIVING CHANNEL, PIPE OR STORM

SEWER SYSTEM. FOR THOSE SITES WHERE RUNOFF IS DISCHARGED INTO A PIPE OR PIPE SYSTEM, DOWNSTREAM STABILITY ANALYSES AT THE OUTFALL OF THE PIPE OR PIPE SYSTEM SHALL BE

PERFORMED.

b. ADEQUACY OF ALL CHANNELS AND PIPES SHALL BE VERIFIED IN THE FOLLOWING MANNER:

(1) THE APPLICANT SHALL DEMONSTRATE THAT THE TOTAL DRAINAGE AREA TO THE POINT OF

ANALYSIS WITHIN THE CHANNEL IS ONE HUNDRED TIMES GREATER THAN THE CONTRIBUTING

DRAINAGE AREA OF THE PROJECT IN QUESTION; OR

(2) (A) NATURAL CHANNELS SHALL BE ANALYZED BY THE USE OF A TWO-YEAR STORM TO VERIFY

AutoCAD SHX Text PROJECT DESCRIPTION The owner of this project is the Virginia Department of Corrections, and the project is located at the Fluvanna Women's Correctional Center facility in Fluvanna County, Virginia. The purpose of this project is to construct a parking lot expansion. Improvements associated with the project include a parking lot expansion approximately 180' X 240', Major components of the project that disturb the existing soils are anticipated to occur in these major steps as: Initial rough grading Fine grading to proposed design finish grades The proposed land-disturbance activities consist of earthwork associated with preparing the sub-base for the entrance and parking lot. The entire limits of disturbance related to the construction is approximately 0.96 acres. EXISTING SITE CONDITIONS The proposed site for the parking lot expansion is located across the entrance drive from the existing parking area. The area being developed currently is an open grass field. The grades slope downward across the site, with an average slope of approximately 3%. There are no known current erosion problems that exist on the site. Drainage from the site flows overland in a south westerly direction to the existing BMP. SOILS "The soils at this site appear to consist predominantly of fine-grained soils that classify as silty loam and are classified as hydrologic soil group "B" & "D". CRITICAL EROSION AREAS No critical areas exist within the limits of the project site. The only potential pollution sources include on-site fueling storage and operations for construction equipment, as well as the storage of fertilizer on-site used in establishing temporary and permanent seeding. No discharges from industrial activities are anticipated on this project other than normal construction practices. EROSION AND SEDIMENT CONTROL MEASURES The Phase 1 erosion and sediment control measures will be designed to retain sediment on-site to the maximum extent practicable. All perimeter erosion control measures must be properly selected, installed, and maintained in accordance with the manufacturers' specifications and good engineering practices. If periodic inspections or other information indicates a control has been used inappropriately or incorrectly, the contractor must replace or modify the control for site specific situations. If sediment escapes the construction site, off-site accumulations of sediment must be removed at a frequency sufficient to minimize off-site impacts (e.g. construction related sediment in streets could be washed into storm sewers by the next rain and pose a safety hazard to users of surrounding access drives). Litter, construction debris, and construction chemicals exposed to stormwater shall be prevented from becoming a pollutant source for stormwater discharges by screening outfalls and picking up litter daily. STRUCTURAL PRACTICES The following measures will be used to control erosion and sediment-laden runoff on this project. See the Erosion & Sediment Control Plan for locations of specific erosion control measures. Construction Entrance: Used to reduce mud and sediment tracked onto adjacent roads (VE&SCH : Used to reduce mud and sediment tracked onto adjacent roads (VE&SCH Standard and Spec. 3.02). If mud or sediment is transported onto a paved road surface, the road shall be cleaned thoroughly at the end of each day. Sediment and mud shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment and mud are removed in this manner. Silt Fence: Used to intercept and detain small amounts of sediment from disturbed areas during : Used to intercept and detain small amounts of sediment from disturbed areas during construction operations and to prevent sediment from leaving the site (VE&SCH Standard and Spec. 3.05). Sediment Trap: A temporary ponding area formed by constructing an earthen embankment with a A temporary ponding area formed by constructing an earthen embankment with a stone outlet to detain sediment-laden runoff from small disturbed areas long enough to allow the majority of the sediment to settle out (VE&SCH Standard and Spec. 3.13). Dewatering Structure: A temporary settling and filtering device for water which is discharged from A temporary settling and filtering device for water which is discharged from dewatering activities to filter sediment laden water prior to the water being discharged off-site. (VE&SCH Standard and Spec. 3.26). Temporary Seeding: Applied to denuded areas within seven days after final grade is reached on any : Applied to denuded areas within seven days after final grade is reached on any portion of the site. Temporary soil stabilization shall be applied within seven days to denuded areas that may not be at final grade but will remain dormant (undisturbed) for longer than 14 days (VE&SCH Standard and Spec. 3.31). Permanent Seeding: Used to establish vegetative cover and to reduce silt runoff for any areas not : Used to establish vegetative cover and to reduce silt runoff for any areas not paved or roofed. Permanent stabilization shall be applied to areas that are to be left dormant for more than one year (VE&SCH Standard and Spec. 3.32). VEGETATIVE PRACTICES Topsoil will be stripped from from areas to be graded and stockpiled for later use. Stockpile locations will be located within the construction limits on-site and are to stabilized with temporary vegetation. The contractor will submit a supplementary erosion and sediment control plan to the Owner and the Department of Environmental Quality (DEQ) for review and approval covering any off-site stockpile areas prior to any off-site activities commence. The proposed design intent is to balance the earthwork on site so that the materials cut will be used as fill, and no off site disposal or borrow is needed. STABILIZATION PRACTICES No specific schedule other than those guidelines provided in the VE&SCH descriptions for vegetative practices will be used for temporary and permanent seeding measures. Contractor will maintain a record of all major grading activities, temporary or permanent construction activities, and when stabilization measures are implemented. This record shall be kept throughout the duration of the project. The contractor will ensure that these records are maintained, updated and become a permanent part of this overall plan. Construction will be sequenced so that grading operations can begin and end as quickly as possible. Stabilization measures shall be implemented on disturbed areas as soon as practicable. Upon reaching final grade, all graded slopes must be immediately seeded and fertilized to ensure proper stabilization. Permanent seeding shall be installed within 7 days of reaching final grade. Denuded areas which are not at final grade but which will remain dormant for more than 30 days shall be temporarily seeded. Areas that are not to be disturbed must be clearly marked with flagging or signage. After the construction is completed, the site will be permanently stabilized with a combination of buildings, pavement, landscaping, and permanent seeding in accordance with VE&SCH Standard and Specification 3.32. STORMWATER RUNOFF CONSIDERATIONS Stormwater runoff will be managed through the use of curb and gutter along the low side of the parking area. There will be a 4' curb flume with rip-rap outlet at the low point of the parking lot. Runoff from the proposed improvements will be conveyed through the curb flume and outlet protection into an adequately sized existing BMP. OTHER CONTROLS Materials, Garbage, Debris No solid material (which includes building materials, garbage, and other miscellaneous debris) shall be discharged to surface waters of the State. Construction materials which could be carried off-site by stormwater shall be picked up daily and placed in appropriate waste disposal containers. All waste materials will be collected in a securely sealed dumpster. The dumpster shall meet all solid waste management requirements, and all trash and construction debris from the site shall be deposited in the dumpster. The dumpster will be emptied a minimum of once per week or more often if necessary, and trash will be hauled as required by local regulations. No construction waste will be buried on-site. All personnel will be instructed on proper procedures for waste disposal. Compliance with State & Local Waste, Sanitary, and/or Septic Regulations A minimum of one portable sanitary unit will be provided for every ten (10) workers on the site. All sanitary waste will be collected from the portable units a minimum of one time per week by a licensed portable facility provider in compliance with local and state regulations. All sanitary waste units will be located in an area where the chances of the unit contributing to stormwater discharge is negligible. No other temporary sanitary sewer facilities are planned for the site during construction.No other temporary sanitary sewer facilities are planned for the site during construction.o other temporary sanitary sewer facilities are planned for the site during construction.

OTHER CONTROLS (CONTINUED) (CONTINUED) Expected Construction and Waste Materials The following construction and waste materials could potentially be stored on-site: topsoil, fill dirt, excavated material, lumber, sheetrock, floor coverings, electrical wire and fixtures, paints, stains and finishing treatments, cleaning solvents, brick, block and mortar, seed, fertilizer, herbicides, stone, concrete products, asphalt, petroleum based fuels and lubricants for equipment, and PVC and ductile iron pipe. Any stockpiles of topsoil, excavated material or fill dirt that are needed shall be surrounded on the downslope side by silt fence. Fertilizer and herbicides must be kept in watertight containers, preferably in portable storage units and out from exposure to the weather during storage on-site. Care must be taken to minimize spillage of fertilizer if mixing operations are required to prepare the fertilizer for application. These products will be applied at rates that do not exceed the manufacturer's specifications. Practices such as good housekeeping, proper handling of hazardous products, and proper spill control practices shall be followed to reduce the risk of spills and discharging into the stormwater runoff. To minimize the affect of any potential spills, maintain all on-site fueling operations as far away from surrounding surface waters and drainage facilities as is practical. Quantities of products stored on-site will be limited to the amount needed for the job. Products and materials will be stored in a neat and orderly manner, and in appropriate containers will be according to the manufacture's recommendations. The disposal of product containers shall also be in accordance with the manufacturer's recommendations. If overnight storage of fuel is required, the fuel storage container must be equipped with a fueling mechanism disable device. Daily inspections of the fuel storage container must be implemented to detect the presence of leaks. The fueling operator shall have a safe fill, shutdown, and transfer procedure in place to minimize spillage during fueling activities. The operator must maintain a fully equipped spill kit on site at all times with the stored fuel. The kit must at least include absorbent mats or material to cleanup any spilled fuel. For any fuel spill on site equal to or exceeding 25 gallons, immediately create an appropriately-sized berm around the area of spillage to minimize surface movement of the fuel. Contact local HAZMAT authorities, the Engineer, and the regional DEQ office as quickly as possible to report the spill and seek further assistance with spill cleanup. Containers for petroleum based products such as fuels, lubricants and tars will be inspected daily for leaks and spills. This includes on-site vehicle and machinery daily inspections and regular preventive maintenance of such equipment. Equipment maintenance areas will be located away from state waters, natural drainage and stormwater drainage inlets. In addition, temporary fueling tanks shall have a secondary containment liner to prevent or minimize site containment. Discharge of oils, fuels, and lubricants is prohibited. Proper disposal methods will be collection in a suitable container and disposal as required by local and state regulations. All paints, finishes and solvents products will be stored in tightly sealed original containers when not in use. Excess product will not be discharged to the stormwater collection system. Excess product, materials used with these products, and product containers will be disposed of according to manufacturer's specifications and recommendations.
