ABSTRACT

The City of Los Angeles performed an in-depth evaluation of the vulnerabilities associated with climate change and the impacts on its wastewater and stormwater infrastructure as a critical part of the City’s One Water Los Angeles 2040 Plan. A climate change risk assessment was performed for the City’s wastewater and stormwater assets for a time horizon through the year 2040 and resilience strategies were developed with estimated costs to mitigate those risks.

KEYWORDS: water utilities, climate change, resilience, adaptation strategies.

INTRODUCTION

For the first time, the City of Los Angeles performed an in-depth evaluation of the vulnerabilities associated with climate change and the impacts on its wastewater and stormwater infrastructure. The evaluation was performed as a critical part of the City’s One Water Los Angeles 2040 Plan – a strategic vision and a collaborative approach for integrated water management that will guide the City with strategic decisions for water resource related projects, programs, and policies that will make Los Angeles a resilient and sustainable City. The key issue addressed was: How do current and future climate conditions impact the City’s wastewater and stormwater assets through 2040 and what needs to be done to mitigate it?
