do they have dog walking, water fountain, restrooms, grill, picnic tables, soccer field, baseball field, playgrounds, and security cameras there ?

There is a softball field, soccer field, porta-potty, and playground. There is a small pavilion, but it may be reserved for parties. Hall Trail connects to other playgrounds and parks within walking distance. The soccer field is a horrible surface, so play at your own risk.

None of the above. Except picnic tables.
