Document Description
Development of a monastery retreat center with associated accessory uses consisting of 17 buildings concentrated on the northern portion of the site with a combined total of 143,671 square feet of programmed space, and including the renovation of one existing 5,318 square-foot residential building into a volunteers’ dormitory. The remaining portion of the site would remain undeveloped except for new landscaping and walkways. The use of the proposed buildings would be meditation halls of various sizes, classrooms, and other instructional spaces, dormitories of various sizes, administrative offices, and multifunctional recreational spaces. The project would include two proposed driveways along South Hacienda Boulevard, and a new multi-use public trail would be developed along the southeasterly portion of the site as part of the project. A total of 297 parking spaces would be provided on-site (266 spaces in a seven-level subterranean garage, 15 on-street spaces designated along project access driveway, 12 spaces in ground-level garages for dormitory occupants, and 4 spaces in the existing building for volunteers' dormitory. The project would retain 11.82 acres (54 percent of open space area) as natural open space and an additional 10.05 acres (46 percent of open space area) as improved open space, consistent with the metrics established in the County's Hillside Design Guidelines.
