RE: Yellowstone Theological Institute Subdivision
Impact to the Water of the U.S.
Dear Wetlands Review Board:
Thank you for reviewing the impact to the Waters of the U.S. (W.U.S.) to the future extension of
Graf Street. Please see the attached wetlands map, WL-1, for reference. The Graf Street
extension is proposed to cross five (5) W.U.S., including those associated with Mandeville
Creek, Woward-Esgar Ditch, Figgins Creek, and two unnamed ditches. The impact at these
crossings will include a culvert, and road and native fill materials. Additionally proposed is to fill
small portions of the Mandeville Creek wetlands that jut out into the property, causing intensive
skewing of the proposed trail along the west property line. Total impact to the W.U.S. area
equals 10,263 square feet, or 0.23 acres.
We propose to mitigate for the impact to the W.U.S. with purchase of mitigation credits. The
primary watercourses within the parcel are ditches that do not contain surface water for a
majority of the year. The Permittee (Yellowstone Theological Institute) intends to purchase
mitigation credits from a “third-party provider” as specified in 33 CFR 332, in this case the
Upper Yellowstone Mitigation Bank, to mitigate the Permittee’s impacts to the aquatic
resources. The bank will be responsible for the off-site compensatory mitigation activities as
required in the Permit and agrees to complete the off-site compensatory mitigation in accordance
with the provision specified in the Mitigation Bank Agreement dated October 12, 2012, executed
by the Corp District Commander on March 7, 2013.
Please feel free to contact me at 586 0262 if you have any questions or concerns.
Sincerely,
Juliene Sinclair, EI
