INTERCEPT AND DIVERT STORMWATER RUNOFF TO STABILIZED OUTLETS AT NON -EROSIVE VELOCITIES. APPLIES WHERE RUNOFF FROM AREAS OF
HIGHER ELEVATION MAY DAMAGE PROPERTY, CAUSE EROSION, OR INTERFERE WITH THE ESTABLISHMENT OF VEGETATION ON LOWER AREAS,
INHERE SURFACE AND/OR SHALLOW SUBSURFACE FLOW IS DAMAGING SLOPING UPLAND, AND WHERE THE SLOPE LENG774 NEEDS TO BE REDUCED
TO MINIMIZE SOIL LOSS.
3.13 TEMPORARY SEDIMENT TRAP. -
A TEMPORARY PONDING AREA FORMED BY CONSTRUC7NG AN EARTHEN EMBANKMENT WITH A STONE OUTLET. TO DETAIN SEDIMENT -LADEN
RUNOFF FROM SMALL DISTURBED AREAS LONG ENOUGH TO ALLOW THE MAJORITY OF 774E SEDIMENT TO SETTLE OUT. USE BELOW DISTURBED
AREAS WHERE THE TOTAL CONTRIBUTING DRAINAGE AREA IS LESS THAN 3 ACRES, WHERE THE SEDIMENT TRAP WILL BE USED NO LONGER THAN
18 MONTHS, AND IT MAY BE CONSTRUCTED EITHER INDEPENDENTLY OR IN CONJUNCTION WITH A TEMPORARY DIVERSION DIKE.
3.14 TEMPORARY SEDIMENT BASIN.
A TEMPORARY BARRIER OR DAM WITH A CONTROLLED STORMWATER RELEASE STRUCTURE FORMED BY CONSTRUCTING AN EMBANKMENT OF
COMPACTED SOIL ACROSS A DRAINAGEWAK TO DETAIL SEDIMENT -LADEN RUNOFF FROM DISTURBED AREAS IN "WET" AND `DRY" STORAGE
LONG ENOUGH FOR 774E MAJORITY OF THE SEDIMENT TO SETTLE OUT. APPLIES BELOW DISTURBED AREAS WHERE THE TOTAL CONTRIBUTING
DRAINAGE AREA IS EQUAL TO OR GREATER THAN THREE ACRES. THERE MUST BE SUFFICIENT SPACE AND APPROPRIATE TOPOGRAPHY FOR THE
CONSTRUCTION OF A TEMPORARY IMPOUNDMENT.
3.18 OUTLET PROTECTION:
STRUCTURALLY LINED APRONS OR 07HER ACCEPTABLE ENERGY DISSIPATING DEVICES PLACED AT THE OUTLETS OF PIPES OR PAVED CHANNEL
SECTIONS TO PREVENT SCOUR AT STORMWATER OUTLETS, TO PR07ECT THE OUTLET STRUCTURE, AND TO MINIMIZE THE P07EN77AL FOR
DOWNSTREAM EROSION BY REDUCING THE VELOCITY AND ENERGY OF CONCENTRATED STORMWATER FLOWS APPLICABLE TO THE OUTLETS OF
ALL PIPES AND ENGINEERED CHANNEL SECTIONS.
3.19 RIPRAP:
A PERMANENT, EROSION -RESISTANT GROUND COVER OF LARGE, LOOSE, ANGULAR STONE WITH FILTER FABRIC OR GRANULAR UNDERLINING. TO
PROTECT THE SOIL FROM THE EROSIVE FORCES OF CONCENTRATED RUNOFF, SLOW THE VELOCITY OF CONCENTRATED RUNOFF WHILE ENHANCING
THE P07EN77AL FOR INFILTRATION, AND TO STABILIZE SLOPES WITH SEEPAGE PROBLEMS, AND/OR NON -COHESIVE SOILS. USE WHEREVER SOIL
AND WATER INTERFACE AND THE SOIL CONDITIONS, WATER TURBULENCE AND VELOCITY, EXPECTED VEGETA7VE COVER, ETC., ARE SUCH THAT
THE SOIL MAY ERODE UNDER THE DESIGN FLOW CONDITIONS.
3.20 ROCK CHECK DAMS:
SMALL TEMPORARY STONE DAMS CONSTRUCTED ACROSS A SWALE OR DRAINAGE DITCH. TO REDUCE THE VELOCITY OF CONCENTRATED
STORMWATER FLOWS, THEREBY REDUCING EROSION OF THE SWALE OR DITCH. THIS PRAC77CE ALSO TRAPS SEDIMENT GENERATED FROM
ADJACENT AREAS OR THE DITCH ITSELF, MAINLY BY PONDING OF THE STORMWATER RUNOFF. THIS PRACTICE, U77LIZING A COMBINATION OF
STONE SIZES, IS LIMITED TO USE IN SMALL OPEN CHANNELS WHICH DRAIN 10 ACRES OR LESS
