Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Section 15301 Existing Facilities
Reasons for Exemption
Class 1 allows for the rehabilitation of deteriorated facilities to meet current standards of public health and safety. The project is limited to replacement of low-slope roofing material and accessories necessary to maintain a working facility. The only project element with limited visibility to the public is a gutter replacement, which is not original and will be replaced in-kind. The Wallis Annenberg Building is a historic era structure constructed in 1913 and assumed to be historic; therefore project drawings have been reviewed by a qualified Preservation Architect who has confirmed the project will not have an adverse effect on the potentially historic resource. The State confirms that no exceptions apply which would preclude the use of an exemption for this project.
