Document Description
The proposed 1100 Rancho Conejo Life-Science Campus Project (Project) is a request for a Development Permit (2022-70164), a Special Use Permit for Alcohol Sales (2022-70165), a Landscape Plan Check (2022-70166), and a Protected Tree Permit (2022-70167) for the Project site, which is located at 1100 Rancho Conejo Boulevard in the City of Thousand Oaks, Ventura County, California. The Project Applicant is Alexandria Real Estate Equities Inc. The Project site is an 18.99-acre parcel that includes three existing two-story buildings totaling 167,475 square feet: Building B35, 23,761 square feet; B36, 63,333 square feet; and B37, 80,381 square feet. These buildings are used for office and lab space. The property also includes an associated surface parking lot with a total of 596 parking spaces, landscaping (including 77 protected trees of which 45 are oak trees and 32 are sycamore trees), emergency generators, and infrastructure improvements. The buildings on site were occupied by Amgen, an international Life-Science company, through 2017. The buildings have been unoccupied since 2017. The applicant proposes to demolish all existing structures on the Project site and redevelop the site with four buildings totaling 351,164 square feet (a net increase of 183,689 square feet) flanking a central courtyard and surrounded by a surface parking lot with a total of 854 parking spaces, and associated landscaping, lighting, emergency generators, and infrastructure improvements. The Project site is within the Industrial Park (M-1) zone district with an Industrial land use designation. The buildings are targeting a Leadership in Energy and Environmental Design (LEED) Silver certification. A one-story amenity building (25,840 square feet) would include a 5,300-square-foot restaurant and lounge open to the public, and the remainder of the building would include conference rooms and a fitness center open to employees only. Three two-story lab/office buildings, totaling 325,324 square feet (Building A: 130,426 square feet; Building B: 67,726 square feet; Building C: 127,172 square feet), would consist of approximately 40% office and 60% lab uses, with common lobbies, restrooms, and loading areas. Of the 77 protected trees located on site, 13 (9 oak trees and 4 sycamore trees) are to be protected in place, 10 oak trees are to be relocated on site, and 54 (31 oak trees and 23 sycamore trees) are proposed to be removed and replaced at a 3:1 ratio. The applicant estimates a net 39,000 cubic yards of fill grading will be required (cut: 26,000 cubic yards; fill: 65,000 cubic yards). Vehicular and pedestrian access to the site is proposed from Ventu Park Road. Delivery vehicle and emergency access would be provided from both Rancho Conejo Boulevard and Ventu Park Road. Project construction activities are anticipated to take approximately 36 months. Employees would have access to the site 24 hours a day, 365 days a year. The public would have access to the restaurant and lounge only, from 7:00 a.m.–11:30 p.m. Monday through Sunday, for breakfast, lunch, and dinner. The Project includes a request to sell alcohol consistent with the Department of Alcohol Beverage Control License Type 48 (On-Sale General–Eating Place), which authorizes the sale of beer, wine, and distilled spirits for consumption on the licensed premises and the sale of beer and wine for consumption off the licensed premises. The operator must maintain the licensed premises as a bona fide eating place. Approximately 2,250 employees would work on the campus, but not all at the same time. Approximately 2,168 lab/office employees are anticipated to work on the campus. Approximately 70 employees are anticipated to work at the restaurant, and approximately 8 employees are anticipated to work in the fitness center. Special events with 100 or fewer people are expected to occur on the campus as frequently as weekly and during the hours of 7:00 a.m. and 9:00 p.m.
