Plans to convert a vacant lot into a senior living facility in Goleta have crept along since they were first introduced to the Santa Barbara school board late last year. Colloquially referred to as Granny’s Field, and officially known as the Tatum property, the 23-acre site located near Hollister and Turnpike came one step closer to development after the school board recently approved collaborating with The Towbes Group. The proposal includes 260 units on approximately 280,000 square feet space, including independent and assisted-living apartments. Common areas and joint-use space for the district will also be included, but those details will be hashed out in the future. The project is expected to take several years to complete.
