皆さんのおっしゃる通りでした。
Each of our six sister cities has expressed an interest in developing a
monument or memorial within the sister city park space in the near future.
A maintenance fund will be established to cover the cost of any general maintenance and any vandalism or graffiti removal. This fund will ensure that all maintenance costs related to sister cities monuments/ memorials are covered by our sister city partners.
