The Sienna Associations (also known as the Association) include the  Sienna Residential Association (SRA), for the original seven villages (Anderson Springs, Avalon, Bees Creek, Shipman’s Landing, Steep Bank East, Steep Bank West and Waters Lake) – and the  Sienna Community Association (SCA) for villages of Sawmill Lake and Sienna Oaks – and lastly the  Sienna Townhome Association (STHA).  

Sienna is unique in that its residential Associations are managed on-site, something not every community can boast.

The benefits of on-site management are many . . . prompt response to questions, firsthand awareness of community issues, closer interaction with service providers and more availability for inspections, to name a few. On-site management allows staff and residents to develop a real trust, with greater residential involvement and staff response.

The Associations’ primary responsibilities include protecting and enhancing property values, maintaining common areas, enforcing deed restrictions, and providing lifestyle opportunities.
