The four design alternatives and "no build" have been evaluated for the criteria in the tables below.

The project area is primarily in the city of Sherwood with a portion of the project outside of the city limits. The portion of the project outside of the city of Sherwood is subject to Article VII land use review, shown in Table 2.

Built and Planned Environment
Impacts to existing and proposed land uses	Least impactful to adjacent properties. Some right-of-way acquisition required, but no change to land uses.	Most impactful to adjacent properties. Right-of-way acquisition and relocations required. Would result in changes to land uses.	Most impactful to AF-20 property. Reduced property size, but no change to land uses.
