Future Embankment Inspection Process

Hi all,
One of the main goals of the Vegetation Management / Remediation
project, besides making these dams safer, is to enable the NY
Canal Corp (NYCC) to properly INSPECT these Earthen Embankments
on a regular basis. Currently there are many areas where the
Embankments haven't been inspected at all for over 75 years.
It's a serious issue that is being fixed, once completed I'm
sure more thorough Inspections will occur. Regular Inspections
are required on the entire dam.
The basic premise here is simple: Earthen Dams are ONLY safe if
routine Inspections are performed from the TOP & BOTTOM of the
Embankments
Here's a GREAT post with a link to a very comprehensive
Embankment Dam Inspection Guide

ERIE CANAL EMBANKMENT INSPECTION:
According to NYCC the current Canal Inspectors will soon start
inspecting these Embankments following prescribed guidelines and
in a more methodical manner. Currently Canal Walkers have ONLY
inspected by looking down the slopes from the Erie Canal Trail
(ECT). With all the trees in the way, all the vegetation
covering the slope surface these past inspections have been
hampered to say the least.
None of the dams have been examined from the Toe of Slope
looking upward to the ECT in many years, even though that is the
best method to see leakage issue properly. Having a uniform
covering on the Embankment is still another benefit to these
Inspectors. Just like in our own yards the grass that has more
water always is a little greener, always a little taller between
cuts. Toe of Slope inspection is critical.
Once the Erie Canal Embankments become grass-covered, these
routine Inspections will be easier to perform, and much more
effective. But that does come at a cost. Plan now for Canal
Walkers doing their Inspections from TWO locations, one is from
the ECT looking down slope like today. The other will be new for
all of us living adjacent to the Embankment Slopes. On their
"return walk" those Canal Walkers will most likely be inspecting
along the BOTTOM of the slopes (along the Toe) looking upward.
They are looking for water issues, burrowing animals and other
items on their checklists. That will mean we may see them along
each of our properties anytime of the day during daylight hours.
Just a heads up... maybe get to know them and help point out
issues on your own properties if needed to assist them. It is
just another by-product of making AND keeping the Erie Canal
safe. It will be a big change for some who've never had Canal
Walker/Inspectors along their property borders. Remember this..
they are just doing their JOBS.. trying to insure WE are all
that much safer when the Erie Canal is Full
For those interested in Earthen Embankment Inspections, I've
included links to a website as well as several Guides &
Tutorials. I've linked to a shared folder on Google Drive in
some cases due to file size and limitations in this Forum for
