The following items will not be included nor collected for the project, due to the amount of time allotted for this project; considerations such as geotechnical lab sampling/testing and utilities (sanitary sewer, water, storm, gas, electrical, etc.) will not be included in the final design. While the Flagstaff Urban Trail System (FUTS) will also not be included into the design process, it will be considered for further later development.
