Andrew,
In general the monitoring plan adheres with what we typically see in mitigation sites, however, I would like to clarify or
call out a few items:
1. It appears that some of this site is/was in pasture. If any of this site was prior pasture then before planting the
fescue should be treated and then, if possible ripped. This will help the bare roots a great deal.
2. In the Monitoring Section (8.0) they reference the USACE February 8, 2013 Monitoring Requirements, later in
Table 4. they list the required metrics. This guidance requires bank pins, but I would not recommend that they
need to install bank pins.
3. For vegetative monitoring, they simply state in Table 4, "Vegetation will be monitored using a standard sampling
method"..., the method in the guidance document is pretty specific, meaning that they need to have at least 3
fixed plots. I would make sure they have at least 3 plots, but recommend 4. The guidance calls for all fixed plots
but I think 2 fixed and 2 random plots would be fine.
4. Table 4 also refers to mapping of exotic veg, encroachments and photographs. These items should all be included
in monitoring annual plan view which identifies, veg plot location and success, stream problem areas, areas of
exotic vegetation and any encroachments. They (Wildlands) typically do this , at EEP/DMS its call a Current
Condition Plan View (CCPV).
5. In Table 3 of the Performance Standards, one of their veg metrics is no more than 15% cover of exotic/invasive
species, I would lower that % to 10%.
I think that about does it.
If you have any questions, let me know.

Mac,
The Tryon International Equestrian Center has submitted a request for modification of their 401 Water Quality
Certification to include permittee responsible off-site mitigation, rather than payment into DMS. I believe you have been
copied on some of the correspondence regarding the plan.
Could you take a look at the plan (Jennifer has a copy) and let us know if the proposed monitoring is in line with what you
would normally require for a mitigation site?
Thanks,
Andrew W. Moore, P.G.
