In addition to preparing the City's 2015 UWMP, Consultant has developed and revised UWMPs and/or WSCPs for numerous agencies. Several of these agencies face similar water supply reliability issues as the City and also face demand hardening, creating a significant challenge in the face of mandatory water use restrictions and decreased supply reliability. Consultant addressed these issues through a rigorous quantitative assessment of current water use and identification of the sectors and end uses with the greatest potential for water savings. As part of this effort, Consultant developed and used our DIRT, a user-friendly model that supports quantitative design of WSCPs, such as will be required pursuant to Making Water Conservation a California Way of Life. Given the recent and severe drought, Executive Order B-29-15, and the SWRCB's Emergency Drought Regulations, and recent Making Water Conservation a California Way of Life (AB-1668/SB-606) legislation, WSCPs are subject to increased scrutiny and will be required to be more consistent and rigorous. Based on review of available information, it appears that the City surpassed its SWRCB-mandated water conservation target of 8% during the drought. Consultant will work with the City to develop an approach to update its WSCP that will benefit from lessons learned during the recent drought, assess options to reduce water demands under projected dry -year scenarios, and meet the additional requirements under the new legislation. Additionally, Consultant is aware that processed AMI data is available from a recent residential outdoor water use study. City will make data available to Consultant to quantify effectiveness of potential water demand reduction actions during a drought. As part of this task, Consultant will update the City's existing WSCP for inclusion in the 2020 UWMP per CWC §10632 and reflect: ■ The significant strides the City and its customers have made in recent years in terms of water conservation (i.e., demand hardening); ■ The local public policy interests in how water shortages are allocated; ■ The mechanisms by which the necessary cutbacks can be realized; ■ The potential impacts of the projected cutbacks on the City revenues and staffing and the local economy; and ■ The lead time required to implement specific actions during a water shortage (e.g., adding additional meter readers in order to move to more frequent billing). City will provide Consultant with common language through BAWSCA to address the new drought risk assessment (DRA) requirement to assess water supply reliability (or vulnerability) for a period of drought lasting five consecutive water years (CWC §10635(b)). Pursuant to CWC §10632.5, updated WSCPs are also required to include relevant available seismic risk assessment and mitigation information to assess the vulnerability of each of the various facilities of a water system and mitigate those vulnerabilities. The UWMP may rely on existing documents, and information will be available by City (e.g., in existing hazard mitigation plans and/or America's Water Infrastructure Act of 2018 [AWIA] REV: 10-14-2020 MI ATTY/AGR.2020.240/EKI Environment & Water, Inc.
