Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs Monterey One Water Bureau of Reclamation Task 3 Objectives and Metrics
Approach to Basin Study Objectives Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs Monterey One Water Bureau of Reclamation • Objectives are needed to evaluate adaptation and mitigation strategies • Early identification of objectives to ensure modeling and analyses will provide needed information • TM No. 1 Study Metrics identified proposed study objectives • We are seeking your comments and approval to proceed
Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs Key Terms Monterey One Water Bureau of Reclamation • Objectives: Essential reasons for & purposes of an organization or activity in broad, inclusive terms. • Performance Measures (Metrics): Indicators of how well the organization is achieving its Objectives. Should be quantifiable criteria for assessing performance. • Performance Targets: Quantified & agreed-upon levels of performance that indicate Objectives are being achieved.
Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs Approach to Developing Study Objectives Monterey One Water Bureau of Reclamation • The Basin Study must primarily satisfy the requirements of the Federal legislation that authorized the Basin Study program. • Basin Study also addresses local water resources objectives that have been identified within the study area. • Objectives have been identified at the local level through: – IRWMPs – Existing groundwater management plans – Sustainability Groundwater Management Act (SGMA) requirements.
Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs Sources of Local Objectives Monterey One Water Bureau of Reclamation • IRWMPs: – Monterey Peninsula, Carmel Bay, and South Monterey Bay – Greater Monterey County – San Luis Obispo County • Groundwater Management Plans – Monterey Groundwater Management Plan – Paso Robles Basin Groundwater Management Plan • SGMA – Sustainable Management Criteria BMP – List of “undesirable results”

Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs “Metrics” Identified in TM No. 1 Monterey One Water Bureau of Reclamation • Metrics are quantifiable outputs from the modeling and technical analysis • “Metrics” address the “Performance Measures” of each “Objective” • Metrics will identify how well a mitigation measure meets a “Performance Target” • TM No. 1 identified the proposed Metrics to be measured in the models
Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs Metrics Provided by the Modeling Tools Monterey One Water Bureau of Reclamation • Table 7. Components of Basin Study Climate Metrics: Climate Variable, Spatial Scale, Temporal Scale, and Statistic – Table 8. Geographic Areas Considered in Computing Basin Study Climate Metrics – Table 9. Weather Station Locations Considered in Computing Basin Study Climate Metrics • Table 10. Water Demand Metrics • Table 11. Water Supply Metrics • Table 12. Water Management Metrics • Table 13. Basin Study Objectives and Associated Metrics
Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs Metrics Correlated to Proposed Objectives Monterey One Water Bureau of Reclamation • The metrics presented TM No. 1 are compared to the Objectives in Table 13 to see the extent that the metrics serve to measure the success of strategies in meeting objectives • Table 13 Excerpt:
Monterey Peninsula Water Mngmnt District Monterey County Water Resources Agency San Luis Obispo County, Dept. of PWs “Approval” of Objectives Monterey One Water Bureau of Reclamation Discussion, comments, or concerns with the objectives? • Please review the final draft of TM No. 1 that is forthcoming • The Project Team needs to proceed with the proposed objectives – Incorporate quantifiable objectives in the models – Develop Performance Measures to be applied to qualitative objectives – Develop screening approach for mitigation actions
