Note the permissions.
The group permissions do not include write.
Only the user "www" may write to that directory.
You are not user "www".
Therefore, you may not write to that directory.

If you want being in group "www" to be sufficient
to be allowed to write to that directory, you need
to "chmod g+w  /usr/local/www/data"
