Jorgensen Associates performed surveying and civil engineering for the conversion of the 1,106-acre JY Ranch to its natural state as part of Mr. Laurance S. Rockefeller’s donation of the ranch to the National Park Service. Mr. Rockefeller’s gift is an important part of this nation’s conservation heritage. The restoration included removal of all buildings, corrals, and roadways, replacing them with trails, stream and lake overlooks, and an interpretative center.
The surveying and civil engineering services provided by Jorgensen Associates during this six year project included extensive survey and mapping, grading and drainage design, bridge and platform design, water and sewer systems, and access roads all in a sustainable manner which eventually led to LEED® Platinum Certification, the first in Wyoming.
