Please find below responses to the comments for Holt Farm (20-085) provided on July 21,
2022 via email in bold green italics:
Vallowable for the swales (Prior Comment 1,b,ii) - The provided swales matting
(and associated maximum allowable velocity) is temporary (since NAG-SC150 is a
temporary matting) but the swales must remain stable/nonerosive in perpetuity.
Please revise the Vallowable values in the table (and calculations if needed) to
reflect the permanent conditions of the vegetated conveyances and ensure that they
will be stable in permanent conditions.
The EZ and swale calculations have been revised to provide permanent
conditions information along with supporting information for the values
chosen/used. All ditches are in a Vmax condition of less than 5ft/sec and
therefore will hold up with a suitable stand of turfgrass.
2. Deed Restriction document BUA reallocation (per our phone conversation today).
You are allowed to allocate a maximum allowable BUA per lot to each individual lot
(or group of lots). If you are changing the amount of BUA for this project by
changing the per lot BUA allocations, you will need to provided revised (original)
deed restriction documents (showing the new BUA allocations), recalculate the BUA
for the site, BUA breakdown by type, and %BUA for the site (Section IV, 8 & 10 of the
Application and Lines 8, 9, 10, 12, & 18 of the Drainage Areas Page of the
Supplement-EZ Form).
Deed restriction, EZsupplement, and storm water application have been revised
to reflect the values per our discussion.
3. Please revise the table in Section IV, 10 of the Application to match the information
shown in the Supplement-EZ Form. The BUA allocated to the individual lots should
be listed on the "On -site Buildings/Lots" line and not broken down by type.
