If not, please explain II. General Project Information Project Title West Lake Tahoe Regional Water Treatment Plant Project Category Restoration Storm Water/Flood Control Waste Water/ Water Supply Project Description (Briefly describe the project, in 300 words or less) The West Lake Tahoe Regional Water Treatment Plant project is the design, permitting, and construction of a permanent surface water treatment plant on the West Shore of Lake Tahoe utilizing Lake Tahoe as the water source. Water service along the West Shore of Lake Tahoe suffers from an inefficient, ineffective, disjointed, delivery system. Separate water systems were constructed subdivision by subdivision, and most are well over 40 years old, some dating back to the early 1900's. There are seven different water systems serving approximately 2,800 connections and none are in full compliance with current California Department of Public Health (CDPH) standards. Several are in violation of primary drinking water standards and others are in violation of secondary drinking water standards. All have source capacity issues for either their primary or back-up sources and there is a lack of adequate storage to meet fire suppression standards throughout the area. Due to the small numbers of connections in each system (most are under 500) these systems are significantly undercapitalized to meet today's drinking water standards. The West Lake Tahoe Regional Water Treatment Plant project will provide adequate water source to address these water supply needs on an integrated, regional basis. The project replaces an interim seasonal water treatment plant that TCPUD constructed in The interim plant has reached its useful life and needs to be replaced. The West Lake Tahoe Regional Water Treatment Plant provides a longterm solution to water delivery needs along the West Shore of Lake Tahoe and offers an integrated, regional approach to improving water quality and water delivery. The project includes design, permitting, CEQA compliance, public outreach and construction.

2 Project Prioritization: Does this project contribute to a larger Project (e.g., TMDL, EIP, Phase 2 of 3)? If so provide description. Political Support List related MOUs, agreements or TACs currently in place. Project Location: Latitude: Longitude: Project Location Description (e.g., along the south bank of stream/river between river miles or miles from Towns/intersection and/or address): Total number of projects 1 submitted by your Agency: Agency Prioritization of this 1 of 1 project (e.g., 3 of 5). The West Lake Tahoe Regional Water Treatment Plant (WLTRWTP) will replace an existing seasonal treatment plant that produces 300 GPM and it will have the capacity to serve up to seven water companies, producing up to 1,820 GPM along the West Shore of Lake Tahoe. TCPUD and the McKinney Water District currently have a Mutual Water Aid Agreement in place and, the new treatment plant will have the capacity to provide water and back-up storage for up to seven of the water companies along the West Shore of Lake Tahoe. TCPUD anticipates agreements with a minimum of several of the water companies in the project area. The project is supported by Placer County Water Agency (they approved a grant for preliminary study) and the CA Department of Public Health. Chamberlands Drive, in Tahoma, CA on the West Shore of Lake Tahoe III. Plan Objectives Addressed For each of the objectives addressed by the project, provide a one to two sentence description of how the project contributes to attaining the objective and how the project will be quantified. If the project does not address any of the draft IRWM plan objectives, provide a one to two sentence description of how the project relates to a challenge or opportunity of the Region (see the bottom of page 4). Objectives: Will the project address the objective? Brief explanation of project linkage to selected Objective Quantification (e.g. acres of streams/wetlands restored or enhanced) WQ1 - Meet approved TMDL standards in accordance with the attainment date, and participate in the development of future TMDLs. -- Project Template Page 2 of 13 12/16/13

3 WQ2 Reduce pollutant loads by implementing measures such as stormwater LID retrofits, erosion control/restoration to meet Water Quality Objectives (WQOs) for receiving water bodies established in the Basin Plan within the planning horizon. The new treatment plant replaces an interim treatment plant that is in the floodplain of McKinney Creek. As part of the project, the interim plant will be removed, improving the floodplain. Improves approximately 1,000 sq. ft of floodplain. WQ3 - Implement water quality monitoring programs through planning horizon, and coordinate annually throughout the Region. WQ4 - Ensure that drinking water supplied by public water systems continues to meet Federal and State standards. WQ5 - Restore degraded streams, wetlands, riparian and upland areas to re-establish natural water filtering processes. WQ6 -Operate and maintain, build, or replace infrastructure for reliable collection, treatment and disposal of wastewater. WS1 - Provide water supply to meet projected demands for a 20-year planning horizon. Currently, seven separate water systems along the West Shore of Lake Tahoe provide water service to 2,800 residents and businesses. ne of these systems is in full compliance with CDPH standards. Two are in violation of primary drinking water standards and all have source capacity issues. In addition, there is a lack of adequate water storage to meet fire suppression standards. The new water treatment plant will increase water production significantly and meet projected demands for up to seven water systems, for the life of the project (50 years). The new treatment plant will provide an emergency backup supply and adequate storage for all seven water systems. The current plant produces 300 GPM, the new plant will produce up to 1,820 GPM.

4 WS2 - Operate and maintain, build, or replace infrastructure to reliably supply water. TThe interim water treatment plant has outlived its useful life and will be removed. It will be replaced to reliably supply water to up to 2,800 residents and businesses. Will meet all state and federal regulations for up to seven water systems and up to 2,800 connections. WS3 - Implement and promote water conservation measures and practices to meet state goals. Water conservation measures are already in place for all TCPUD customers. -- GWM1 - Maintain and monitor groundwater supply to assure future reliability. Constructing a new integrated surface treatment plant will improve the overall, long-term management of California's groundwater resources by providing a viable alternative to groundwater for up to seven water systems. The new plant reduces the area's dependence on groundwater as the only source of water supply. GWM2 - Promote groundwater protection activities for high quality groundwater, and advocate for improvements to impacted groundwater quality through public education. GWM3 - Manage groundwater for multiple uses (e.g. municipal/industrial/agricultural supply and environmental use). ER1 - Enhance and restore water bodies, wetlands, riparian areas and associated uplands to support healthy watersheds, viable native fish, wildlife and plant habitats. Constructing one regional water treatment plant that can serve up to seven water systems and 2,800 domestic water connections reduces the amount of habitat disturbance created by building multiple treatment facilities. One integrated, regional water treatment plant instead of up to seven individual facilities. Project Template Page 4 of 13 12/16/13

5 ER2 - Develop and implement programs to prevent the spread of existing invasive species and colonization of potential future invasive species. ER3 - Implement, in coordination with public and private landowners, activities to manage forest health and wildfire risks. The construction of the WLTRWTP addresses a critical need by increasing the quantity of water available for emergency fire protection. Fire protection for over 2,000 acres of land and up to 2,800 homes and businesses. ER4 - Minimize ecosystem impacts caused by existing and new development. Constructing one integrated, regional water treatment plant instead of multiple treatment facilities minimizes the impact on the environment. One integrated, regional water treatment plant instead multiple plants. IWM1 - Conduct local and regional water-related planning activities within the planning horizon as supported by current and future watershed science. IWM2 - Ensure collaboration among multiple jurisdictions within the Region for information exchange. IWM3 - Increase public education and awareness of watershed functions, protection and restoration needs to encourage stewardship by the public. IWM4 - Promote activities that reduce flood risk. This project is an integrated, regional project that solves water delivery and water storage issues for up to seven water systems. The project involves collaboration with the seven water systems.
