Exempt Status
Statutory Exemption
Type, Section or Code
Section 15269(b)
Reasons for Exemption
The Storm Drain Systems Improvements Project would include the maintenance, repairs, and replacement of stormwater and sanitary sewer infrastructure as discussed above. The Project activities are necessary to avoid emergency disruptions of critical Facility operations during large storm events that can cause massive flooding. Historically, the Facility experienced two 10-year, El Niño winter storm events in 1982 and 2014 that resulted in mass flooding, compromising essential operations, such as access and safety. Damage and defects to the stormwater and sanitary sewer system, caused by devaluation due to use, will likely fail within the next five to 10 years and would not be readily available to function in the next 10-year storm event, and therefore, disruptions to critical Facility operations would be imminent. The Storm Drain Systems Improvements Project would prevent safety and access concerns in order to maintain services essential to the public health, safety, and welfare of approximately two million people that the Facility serves. Moreover, the Project is anticipated to be completed at a reasonable timeline within the next two years. Project design was completed in mid-2021, while the Project would begin construction in the first half of 2022 and complete construction near the end of 2023. For these reasons, the Project as described in this document qualifies for a statutory exemption under CEQA Guidelines Sections 15269(b) from the environmental review requirements of Title 21 of the San José Municipal Code, implementing the California Environmental Quality Act of 1970, as amended.
