Art,
Below is a list recapping the action items from yesterday’s site visit to R-3421. I’ve also attached my photos. If you have
any questions on these, please do not hesitate to contact me.
Site 18
Repair erosion/sedimentation control (ESC) measures in median area – fencing should be set up as vertical as
possible and sediment coated stone should be removed and replaced with clean, washed stone.
Sediment in stream bed in median appears to be only a film – no additional clean up needed.
Upstream side of crossing – sediment just upstream of pipe inlet needs to be removed (3-4” deep), shovel and
buckets preferred method of removal.
Repair ESC measures upslope of the crossing – drainage ditch should be stabilized and reseeded and eroded
sediment deposited behind the wattles should be removed.
Site 9
Clean up has occurred, but ~3 piles of collected sediment need to be removed from the wetland area (photos
showing clean up of these piles was received 7/7/16).
ESC measures have been improved to increase storage.
Monitor the vegetation in the wetland area – if vegetation has not returned by fall, wetland seed mix should be
planted.
Site 8
Some clean up has occurred, but area is still very wet with standing water in most of the affected area – once
area has dried out, remaining sediment should be removed (at least 3” deep but difficult to tell with standing
water), shovel and buckets preferred method of removal.
A basin is proposed upslope of the wetland area to increase storage of storm flows. Currently a underdrain
pipe outlets to the drainage area. This will need to be extended beyond the drainage way prior to basin
installation
