It seems that the Twitter post "street canyon singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what this post is referring to, as it is a general statement about a street and a canyon in Singapore. It does not provide any specific information or context that would indicate it is related to maintenance or public housing issues. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because it is not possible to determine the type of issue being referred to in the post. The "explanation" field is left blank because there is no additional information to provide.
