Scotts Valley Aquifer Evaluation

2026-11-03

The selected contractor will perform a series of tasks to support the Scotts Valley Aquifer Evaluation , aimed at enhancing the understanding of hydrogeologic conditions within the basin . The scope of services encompasses seven primary tasks , each integral to the successful execution of the study : Task 1 : Background Information Review : Review Scotts Valley specific information . The BVIHM was calibrated and assessed for Big Valley . Additional data from Scotts Valley will minimize uncertainty of storage estimates . Information requested for this task to any local agencies or stakeholders include : Locally obtained groundwater elevation data Aquifer test , step - drawdown test , or any other pumping information within Scotts Valley Location and volumes of future extractions Task 2 : Incorporation of Scotts Valley specific data : Incorporate additional information from Task 1 into the BVIHM . Updates to the model will allow for better estimates of aquifer characteristics . Task 3 : Evaluate Aquifer Inflows , Outflows , and Storage : Water budgets for specific to Scotts Valley will be developed . Recharge in natural vegetation , stream flows into the valley , and groundwater interactions with Clear Lake will be included within the water budget . The total aquifer storage will be calculated and compared against published values from DWR bulletin 118 . Task 4 : Pumping Scenario Evaluation : With input from local agencies , a scenario will be developed that explores the impact of additional pumping for municipal demand ( i . e ., increase pumping in the city of Lakeport ). Task 5 : Develop Technical Memorandum and Presentation : A technical memorandum ( TM ) will be prepared to summarize key points relating to : Outlining updates to the BVIHM . Detailing the water budget terms and interactions based on the BVIHM . Estimating the amount of water available in storage in Scotts Valley . Assess the impacts of additional municipal pumping . Cumulative impacts of water uses to surrounding areas due to project operations . Prepare for and present at two public meetings ...
