WET SEDIMENT BASIN - GENERAL NOTES
1. Sediment basins should not be placed in Waters of the State or USGS blue —line
streams (unless approved by Federal Authorities).
2. Sediment basin's side slopes shall be seeded and, when necessary, stabilized with
vegetative or synthetic matting to prevent the formation of rills and gullies.
3. Porous Baffles should be composed of coir—based materials or TRMs with a light
penetration (open spaces) between 10-35%. These materials should not have loose
straw. Silt Fence may not be used as Porous Baffles.
4. Install skimmer and coupling (as necessary) to riser structure at orifice along
bottom of the principle spillway's riser structure. (Refer to skimmer manufacturer
for installation procedures and skimmer specifications.)
5. Skimmer should be equipped with a mechanism, such as a rope, to allow easy
access to skimmer to unclogged orifice or perform other necessary maintenance.
6. Stormwater runoff entering the basin must be directed into proper BMPs to
prevent erosion along side slopes and to prevent scour at the basin's inlets.
7. An additional cleanout stake for the foreboy area is recommended and should be
marked for cleanout at 50% of provided sediment storage.
8. The elevation of the emergency spillway should be at least 1 foot below the top
of the embankment. The emergency spillway should not be located on fill material,
when possible. Riprop and geotextile liner should be placed on all spillways that
must be located on fill material.

WET SEDIMENT BASIN - INSPECTION AND MAINTENANCE
1. The key to a functional sediment .basin is weekly inspections, routine
maintenance, and regular sediment removal.
2. Attention to sediment accumulations within the basin is extremely important.
Accumulated sediment deposition should be continually checked and removed
when necessary.
3. Remove accumulated sediment when it reaches 50% of the design sediment
storage volume or 1/2 the height of the riser structure,
whichever is reached first.
4. Removed sediment from the basin shall be placed in stockpile storage
areas or spread thinly across he disturbed area. Stabilize the removed
sediment after it is relocated.
5. inspections of sediment basins should be conducted once every calendar
week and, as recommended, within 24—hours of each rainfall event that
produces %—inch or more of precipitation.
6. All temporary sediment basins, which are not to be converted to a
detention basin post —construction, should be removed within 30 days
after final site stabilization is achieved.
7. Disturbed areas resulting from the removal of the sediment basin should be
permanently stabilized and additional BMPs, such as silt fence, should be
utilized to accept stormwater runoff from this disturbed area until final
stabilization is reached.
