RE: October 21, 2009, Wetland Review Board Meeting; Preliminary Gallatin Food Bank
Review
Dear Andy,
The City of Bozeman Wetland Review Board met on October 21st, 2009, for a preliminary
review of the renovation of the Gallatin Valley Food Bank. All five members of the Wetland
Review Board (WRB) were present : Lynn Bacon, Brian Sandefur, Cyndi Crayton, William
Kleindl, and Steve O’Neil - along with Purcie Bennett whom has applied for the WRB position
vacated by Guy Alsentzer. Also present was Melanie Dyba of Bridger Engineers, Inc.,
representing the Gallatin Valley Food Bank, and Kerry Thorpe of the City Planning Department.
st
Following preliminary discussion at that October 21, 2009, WRB meeting, I spoke with Dustin
Johnston of the Planning Department about the two specific issues that the WRB had concerning
the proposed detention basin at the site – the physical location, and size/shape. Dustin assured
me that prior to final review of the project, surface water runoff routing calculations would be
done to insure that the basin was sized properly in order to minimize runoff overflow to
Bozeman Creek.
If this proposed storm water detention basin is sited as shown in the preliminary draft (just south
of the eastward terminus of Bond Street where it intercepts Bozeman Creek), the WRB suggests
the following:
1.) that some type of wetland vegetation is included within the detention basin to
promote surface water contaminant filtering, 2.) that it be deepened approx 1-ft more
than shown in the draft reviewed by the WRB in order to allow wetland vegetation roots
a “shorter reach” to groundwater, and 3.) that the bottom of the proposed detention basin
be constructed with porous gravels and sands to increase percolation rates - reducing the
likelihood of direct overflow of storm water runoff from this detention basin to Bozeman
Creek
Sincerely,
Steve O’Neil
Wetland Review Board Chair
