Inlet Protection - Filter Fabric maintenance
✔✔Maintenance for storm inlet covers is fairly intense, due to the clogging
of filtering material
Storm inlets that do not drain within 24 hours of a storm are in need of
maintenance
Repair inlet covers that are torn, crushed or bent out of design
Replace inlet protection that is:
Missing
Fallen into the storm system
Damaged beyond repair
Once final stabilization has been achieved, remove structure and
sediment and properly stabilize the area
Outlet Velocity Protection desc/purp
✔✔temporary or permanent, structural BMP
designed to prevent scour at stormwater outlets and to minimize the
potential for downstream erosion through velocity dissipation. The most
common types are rip-rap aprons, scour holes, and energy dissipater
blocks/walls but configurations utilizing turf reinforcement mats or other
appropriate materials may be used.
,Outlet Velocity Protection objectives
✔✔Runoff Control
Erosion Control
Post-Construction Management
Outlet Velocity Protection applications
✔✔Pipe outlets
Culverts
Receiving channels
Outlet Velocity Protection inspection
✔✔Inspect according to regulatory timetables
Damage to the geotextile underlay, if used
Scour or erosion under or around the BMP
Sediment, trash or vegetative accumulation
Animal activity burrow
Damage to the outlet protection itself such as movement or degradation of
stone
Outlet Velocity Protection maintenance
✔✔When used, maintain the structural integrity of the geotextile
underlining
Maintain the material used in the BMP; rip-rap, concrete channel, turf
reinforcement mat, etc.
Maintain the soil under and around the outlet protection
,Make sure outlet protection is installed according to the Plan/SWPPP and
continually maintained
Pipe Slope Drain desc/purp
✔✔structural BMPs that use piping material
to convey flow down a slope without causing erosion damage to the slope.
These devices may be installed above or below ground.
Pipe Slope Drain objectives
✔✔Runoff Control
Erosion Control
Pipe Slope Drain applications
✔✔Disturbed slopes before permanent stabilization is achieved or
stormwater management/conveyance structures are installed
To convey concentrated runoff
Pipe Slope Drain inspection
✔✔Signs of erosion at inlet or outlet of drain
Outlet protection
Damage to pipe materials
Separation of adjoining pipe sections
Secure anchoring of drain materials
Proper outlet protection (rip-rap, sediment trap, etc.)
Material blockage of pipes
, Animal activity
Pipe Slope Drain maintenance
✔✔Repair damage to structural materials of drain, when needed
Ensure slope drains are securely anchored
Maintain outlets with outlet protection:
Velocity dissipater
Sediment trap or basin
Repair damaged and separated pipes
Rip-Rap desc/purp
✔✔structural BMP utilizing large, coarse, angular rock, frequently underlain
with filter fabric, designed to:
Protect soil from areas of concentrated flow such as channels or ditches
Stabilize slopes experiencing soil or seepage difficulties
Increase infiltration
Dissipate run-off velocity
Rip-Rap objectives
✔✔Runoff Control
Erosion Control
Post-Construction Management
