Provident Resources Group Inc. has acquired 4.4 acres in Zachary’s Americana traditional neighborhood development, allowing the Baton Rouge-based nonprofit to begin building an $18 million assisted living facility announced 18 months ago.

Provident Village at Americana will have 90 units — 48 set aside for assisted living and 42 for residents with Alzheimer’s disease and dementia issues. The development will have 68,000 square feet of space and will offer dining, daily activities, Wi-Fi and other amenities.

The facility is expected to be completed in summer 2017.

Provident Village has undergone some design changes since it was announced in May 2014. At the time, plans called for Provident Village to include 76 assisted living units and 24 for people with Alzheimer’s and dementia.

The project carried an estimated cost of $20 million and was expected to open by the end of 2015.

Provident Chief Executive Officer Steve Hicks was unavailable Tuesday to comment on the development’s new design.

However, in a prepared statement, Hicks said Provident is excited to bring its “state-of-the-art model” to the rapidly growing community of Zachary.

Provident Village is the nonprofit’s first Baton Rouge-area senior living community. Provident Resources plans four in Louisiana, according to Hicks.

Americana is a 413-acre development with room for more than 800 single-family homes, 482,500 square feet of retail and office space, and multifamily residences.
