BACKGROUND On June 1, 2021, City Council adopted the 2020 UWMP and WSCP, in accordance with the California UWMP Act (Act) prior to the required submittal to the DWR. The 2018 Water Conservation legislative updates to the Act included expanded requirements under the WSCP. The expanded requirements that were adopted in the updated WSCP which effect the PMC Chapter 9.30 include: • Inclusion of the newly required AWSDA process as criteria for assessing a water supplier's water shortage stage, and • Inclusion of a prescribed six stage water shortage level framework. City Council last adopted PMC Chapter 9.30 in June 2016 to include the incorporation of modifications identified as helpful for inclusion to the code after experience gained from activation of the Chapter during the last drought (2015-2016). Since this update, the City has incorporated drought rates through the water rate study process, and made modifications to its defined water wastes (PMC 14.04.060). The incorporation of these updates as well as minor changes added for clarity through gained experience are discussed below. DISCUSSION The proposed changes to PMC Chapter 9.30 Water Management Plan, largely provide consistency with the adopted WSCP update. Staff incorporated these updates into PMC Chapter 9.30 in the following manner: Annual Water Supply and Demand Assessment The AWSDA definition was added to the Chapter. In addition, language was added to incorporate the findings from the AWSDA as criteria to activate a given water shortage stage. Six Stage Water Shortage Framework The WSCP conforms to DWR's six standard water shortage levels corresponding to progressive ranges of up to 10-, 20-, 30-, 40-, 50-percent and greater than 50-percent shortages. The existing PMC Chapter 9.30 recognizes an adequate supply level, four stages of shortage, with one of those stages broken into two sub-stages. The following table shows how each of the WSCP stages were modified in this proposed replacement of the existing PMC Chapter 9.30 water levels to conform with the WSCP: WSCP Water Existing PMC 9.30 Existing PMC 9.30 WSCP Stage Water Shortage Shortage Level Stage Level 1 Up to 10% Adequate Supply Adequate Supply (Voluntary) Up to 20% Up to 20% 2 (Voluntary or 1 (Voluntary) Mandatory) 3 Up to 30% 2 Up to 20% (Mandatory) (Mandatory) Up to 40% Upto 25% 4 (Mandatory) 3a (Mandatory) Page 2 of 4
