CONSTRUCTION SPECIFICATIONS
1. Infiltration basin shall be constructed level (at a 0-0.05 % grade} Do fat construct a basin on a slope
greater than 15 percent. Do not locate within fill soils. Do not construct basin in a location with less
than 2 feet between the bottom of the infiltration basin and the seasonal high groundwater table,
underlying implervious soils, or bedrock (minimum 4 foot separation is recommended). Basin shall not be
constructed if it causes water problems to downgradient properties. It must be a minimum of 15 feet down -
gradtent from structures, located a minimum of 100 feet horizontally from any water supply well, 50 feet
from Class SA waters and 30 feet from any surface water.
2. Pretreatment device for removing sediment and solids must be used to protect infiltration deviars from
clogging. These pretreatment devices include filter strips, grassed swales/ditchoes with check dams, adoemi,
sumps and forebays (sediment traps).
3. If inlet flow is a concentrated source of discharge, an energy dissipater shall be used.
4. A sitespecific hydrogeologic investigation shall be performed to establish the suitab0 ty i of snits for
the infiltration basin. Suitable soils must have an infiltration rate of 0.52 inches per hour or greater.
5. Sizing of infiltration basin shall meet the specifications set forth in the NCDENR Stormwater BM Manual
and must be able to completely dewater within 5 days.
6. The bottom of the infiltration basin must be lined with
a layer of clean sand with a depth of 4 inches
or greater, unless the native soil is equivalent (1 -2% fees or less}
7. Contractor shall use care during construction to minimize compaction of soil on the bottom and walls
of the infiltration basin. Light equipment and construction techniques that minimize compaction shall be used.
8. A miNmum of one observation well shall be installed to periodically verify that the drainage media
is fully draining. The monitoring well shall Consist of a 4 to 6 inch diameter, perforated polyvinyl chloride
(PVC) pipe with a locking cap. The well shall be placed dear the center of the facility or in the general
location of the lowest point within the facility, with the invert at the excavated bottom of the facility.
OPERATION AND MAINPENANCE
The drainage area shall be carefully managed be reduce the sediment load to the infiltration basin.
Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if
needed onfil the plants become established (commonly six weeks). No portion of the infiltration basin shall be fertilized after the initial fertilization required to establish
the vegetation The vegetation in and around the basin will be maintained at a height of approximately six inches. After the infiltration basin is established, it shall be
inspected once a quarter and within 24 hours after every storm event greater than 1.0 inches. Records of operation and maintenance shall be kept in a known set location
and be available upon request
Operation and Maintenance Provisions:
1. Remove any trash debris if present from the entire BMP.
2 If any areas of bare soil and /or erosive gullies have formed around the perimeter of the infiltration basin, regrade the soil if necessary to remove the gully, then
plant ground Cover and provide a ore time application of lime and fertilizer and water until establishuxt.
3. Dispose of any sediment and unclog if applicable any inlet pipe or swale/ditch. If erosion is oncoctng in the Swale /ditch regrade the swale /ditch if necessary to
smooth it over and provide erosion control devices such as reinforced turf matting or r)prap be avoid future problems with erosion.
4. R sediment has accumulated in the forebay (sediment trap) and reduced the depth to 75% of thy, original design depth, find the source of the sediment and remedy
the source. Remove the sediment and dispose of where it will not impact any drainage area. If erosion has occurred or rlprap is deplored, provide additional erasion
protection such as reinforced turf matting or additional ripmp to prevent future erosion. If weeds am present remove by hand if possible or rise a selective herbicide to
prevent killing of preferred ground Cover.
5. If a visible layer of sediment has accumulated in the main infiltration area, snatch for the source and remedy the problem. Remove the sediment and dispose of
where it will not impact any drainage area. Replace any media that was removed in the process and revegetate disturbed areas Immediately. If water is standing more
than 5 days after a storm event, replace the top few inches of filter media and we if this corrects the problem. If so revegetate immediately, if not consult an appropriate
professional for a more extensive repair. If weeds or noxious plans are growing, remove the plants by hand or wipe with herbicide (do not spray).
6. If the embankment has shrubs or trees sprouting or growing, remove immediately, if the embankment requires repair during an annual inspection by an
appropriate professional, make all needed repairs.
7. If the outlet device has clogged or is damaged, clean and dispose of the sediment properly and repair or replace the outlet device.
