In 2010, a third amendment was signed which:
- Amended Section 4 (Goals) - the goals in the original amendment had been accomplished and now one goal of "To work together to develop operating parameters for the use of the Property facilities"
- Amended Section 15 (Termination) - the original agreement specified that the agreement would be reviewed every 10 years and it outlined the 3 options available should termination of the agreement occur. In this amendment, the review period was changed to annually and much of the original wording was removed.
- Recognized the dissolution of Atfalati Recreation District and assigned the rights of the agreement to Tigard Little League and Southside Soccer Club.
