The largest of the seven Dover Housing Authority sites located throughout the city, Whittier Falls -  Mineral and Whittier Parks are made up of 184 units that range from one – four bedrooms in size.  The neighborhood includes the only City of Dover Police Substation (not manned 24 hours a day) which is also used by the full time DHA Police Liaison Officer that is assigned to the neighborhood.

The main office of the DHA is also adjacent to the site as is the Seymour Osman Community Center (SOCC), which includes a successful after school program during the school year as well as a tutoring program.  During the summer months the staff of the SOCC operate recreation programs for residents.  The Center also hosts several neighborhood events such as the annual bike parade and field day; community dinners, Halloween and Christmas parties and other special events.
