various urban planning aspects.

| FOREST KINDERGARTEN |This project explores

the possibilities of land reclamation. The Northeastern Minnesota site is transformed

from a taconite mining operation into a forest

kindergarten. The goal of the project is to re-establish native vegetation using an ecological

succession process while simultaneously educating

the youth by implementing a forest kindergarten program.

“Williston Wetlands” looks at an alternative way of

developing a water treatment facility. The wetland treats

effluent water before draining into the Missouri River,

provides wildlife habitat, and recreation/entertainment to

park users. The vision is to create a large scale central

park within the booming, oil rich city, of Williston, North

Dakota.

SITE CONTEXT n

| MINOT’S RIVERFRONT |Downtown Minot, ND is in the midst of a large-scale renovation, however industrial sites along the Souris Riverfront are still largely present, disrupting the urban landscape. The solution transforms a railway corridor into a 40-acre riverfront park, which preserves local history, provides flood protection and acts as a catalyst for development in the downtown area. Overall, the project reconfigures Minot’s riverfront in an effort to improve the quality of life for the citizens of Minot.

| ORDINANCE GRAPHICS |While interning for the City of

Minot, I was given the task to create graphics for a newly adopted city

ordinance book. A series of graphics were created to graphically illustrate

technical terms, definitions, and codes.
