(a) The State Legislature has found:
(1) that the waters of the state are of limited supply and are subject to ever increasing demands; 4/46
051022AGN
(2) that the continuation of California's economic prosperity is dependent on the availability of adequate supplies of water for future uses;
(3) that it is the policy of the State to promote the conservation and efficient use of water and to prevent the waste of this valuable resource;
(4) that landscapes are essential to the quality of life in California by providing areas for active and passive recreation and as an enhancement to the environment by cleaning air and water, preventing erosion, offering fire protection, and replacing ecosystems lost to development; (5) that landscape design, installation, maintenance and management can and should be water efficient; (6) that Section 2 of Article X of the California Constitution specifies that the right to use water is limited to the amount reasonably required for the beneficial use to be served and the right does not and shall not extend to waste or unreasonable method of use.
(b) Consistent with the legislative findings, the purpose of this model ordinance is to:
(1) promote the values and benefits of landscaping practices that integrate and go beyond the conservation and efficient use of water;
(2) establish a structure for planning, designing, installing, maintaining and managing water efficient landscapes in new construction and rehabilitated projects by encouraging the use of a watershed approach that requires cross-sector collaboration of industry, government and property owners to achieve the many benefits possible;
(3) establish provisions for water management practices and water waste prevention for existing landscapes;
(4) use water efficiently without waste by setting a Maximum Applied Water Allowance as an upper limit for water use and reduce water use to the lowest practical amount; (5) promote the benefits of consistent landscape ordinances with neighboring local and regional agencies; (6) encourage local agencies and water purveyors to use economic incentives that promote the efficient use of water, such as implementing a tiered-rate structure; and (7) encourage local agencies to designate the necessary authority that implements and enforces the provisions of the Model Water Efficient Landscape Ordinance or its local landscape ordinance. (c) Landscapes that are planned, designed, installed, managed and maintained with the watershed based approach can improve California's environmental conditions and provide benefits and realize sustainability goals. Such landscapes will make the urban environment resilient in the face of climatic extremes.

Consistent with the legislative findings and purpose of the Ordinance, conditions in the urban setting will be improved by:
(1) Creating the conditions to support life in the soil by reducing compaction, incorporating organic matter that increases water retention, and promoting productive plant growth that leads to more carbon storage, oxygen production, shade, habitat and esthetic benefits. (2) Minimizing energy use by reducing irrigation water requirements, reducing reliance on petroleum based fertilizers and pesticides, and planting climate appropriate shade trees in urban areas. (3) Conserving water by capturing and reusing rainwater and graywater wherever possible and selecting climate appropriate plants that need minimal supplemental water after establishment. (4) Protecting air and water quality by reducing power equipment use and landfill disposal trips, selecting recycled and locally sourced materials, and using compost, mulch and efficient irrigation equipment to prevent erosion.
(5) Protecting existing habitat and creating new habitat by choosing local native plants, climate adapted non-natives and avoiding invasive plants. Utilizing integrated pest management with least toxic methods as the first course of action.

Note: Authority cited: Section 65593, Government Code; and sections 11 and 30, Governor's Exec. Order No. B-29-15 (April 1, 2015). Reference: Sections 65591, 65593 and 65596, Government Code; and section 11, Governor's Exec. Order No. B-29-15 (April 1, 2015).

(a) A local agency may by mutual agreement, designate another agency, such as a water purveyor, to implement some or all of the requirements contained in this ordinance. Local agencies may collaborate with water purveyors to define each entity's specific responsibilities relating to this ordinance.

3.15.230 Irrigation Audit, Irrigation Survey, and Irrigation Water Use Analysis. (a) This section, 493.1, shall apply to all existing landscapes that were installed before December 1, 2015 and are over one acre in size.
(1) For all landscapes in 493.1 (a) that have a water meter, the local agency shall administer programs that may include, but not be limited to, irrigation water use analyses, irrigation surveys, and irrigation audits to evaluate water use and provide recommendations as necessary to reduce landscape water use to a level that does not exceed the Maximum Applied Water Allowance for existing landscapes. The Maximum Applied Water Allowance for existing landscapes shall be calculated as: MAWA = (0.8) (ETo) (LA) (0.62). (2) For all landscapes in 493.1(a), that do not have a meter, the local agency shall administer programs that may include, but not be limited to, irrigation surveys and irrigation audits to evaluate water use and provide recommendations as necessary in order to prevent water waste. (b) All landscape irrigation audits shall be conducted by a certified landscape irrigation auditor.

3.15.240 Effective Precipitation.
(a) A local agency may consider Effective Precipitation (25% of annual precipitation) in tracking water use and may use the following equation to calculate Maximum Applied Water Allowance:

MAWA = (ETo - Eppt) (0.62) [(0.55 x LA) + (0.45 x SLA)] for residential areas.

MAWA = (ETo - EPPT) (0.62) [(0.45 x LA) + (0.55 x SLA)] for non-residential areas.

DISSCUSSION/DIRECTION
Lithium Valley Economic Opportunity Investment PlanLITHIUM VALLEY ECONOMIC OPPORTUNITY INVESTMENT PLAN Summary
Lithium/rare-mineral mining/processing/manufacturing and renewable energy generation/storage possess the opportunity to propel the economic future of Imperial County residents for generations.

Introduction
The County of Imperial desires to increase the overall wealth of its residents through private economic investment into the Imperial Valley Region in the form of lithium and rare mineral extraction, processing and manufacturing/packaging for end-user applications and renewable energy generation/storage in the form of geothermal, solar, wind and energy storage. The Imperial County Lithium Valley Economic Opportunity Investment Plan will be accomplished through specific actions of the County of Imperial, State of California and the United States Federal Government.Lithium is a vital mineral in the rechargeable batteries used by consumers in portable computing devices, electric vehicles and battery storage. More than 80% of the world’s raw lithium is mined in Australia, Chile, and China. Currently, Currently, China controls more than half of the world’s lithium processing and refining and has three fourths of the lithiumion battery mega factories in the world, according to the International Energy Agency.Today, the United States has only 1% of global lithium being mined and processed, according to the U.S. Geological Survey. Imperial County, California is blessed with an abundance of Geothermal Brine at the Salton Sea.

The earth heated brine is rich in critical minerals needed for the production of batteries and alloys, including lithium, manganese and zinc. ,Industry professionals estimate there may be as much as fifteen (15) million tons of lithium in Imperial County that would take 50-100 years to extract. Additionally, there is an estimated 1,000-1,500 MW of additional geothermal energy generation available. The mining of lithium (and other rare-earth minerals) in addition to geothermal power generation provide the opportunity for the United States to have greater control over needed material in the supply chain for electric vehicles and consumer/commercial electronics while providing greater stability to our energy supply. Benefits of Economic Investment County (Local)Employment opportunities (construction and operation).

Education/training opportunities for persons desiring a career in lithium/rare mineral extraction, processing and manufacturing/processing or renewable energy generation/storage from geothermal, wind and energy storage. Lithium Valley Economic Opportunity Investment Plan (Imperial County LVIP) Tax Revenue improved and consistent tax base for which the County can provide appropriate government level services to its residents (in the form of public safety, infrastructure, judicial, social services and quality of life including recreational and cultural/arts). State of California Employment opportunities which reduce individual reliance on social services.
39/46
051022AGN
Education/training providing for an enhanced workforce to propel a variety of industries (primary and secondary). Tax Revenue providing financial resources to the State of California to fund education (K16+), infrastructure, public safety, social services and quality of life activities. Environmental improvements by providing necessary products to propel rechargeable zero-emission transportation.

Digital connectivity and productivity by providing necessary resources used for consumer and commercial application communication. Vertical production capability to increase assembly/manufacturing in California, creating products exported domestically and internationally. Energy Supply stability is enhanced by additional base-load renewable energy generation from geothermal facilities providing needed power when solar/wind is unable to produce. Renewable Energy compliant with Renewable Portfolio Standards (RPS) in the form of geothermal energy generation produced in California for Californian’s.

United States Federal Government National Security: lithium/rare-minerals and renewable energy generation are key to the National Security interests of the United States. The case for renewable energy is simple – its cleaner and safer for the environment and it is domestically produced. For lithium and rareminerals, high value communication products (both consumer and commercial scale) depend on these elements. Reliance on foreign nations for these products places our communication systems at risk of geopolitical instability. Environmental transformation: as the United States continues marching toward rechargeable vehicles, lithium is an essential element for batteries. In order to achieve its climate change goals, the country needs a long-term, stable and preferably domestic source of lithium, otherwise the United States is at the mercy of other nations which again exposes our interests to geopolitical instability.

Supply Chain Certainty: historically, United States consumer demand for passenger vehicles and light trucks exceeds fifteen million vehicles per annum. This is exclusive of commercial and mass-transit vehicles. The ability to deliver vehicles to consumers at a “affordable” price is dependent on mass production in order to maximize efficiency. Supply chain certainly is at the heart of scaled efficiency. As with many other raw and semi-finished materials, it is incumbent on the United States to have capacity within our nation. Lithium Valley Economic Opportunity Investment Plan (Imperial County LVIP) Self-Determination In its purest form, self-determination is defined as the process by which a person controls their own life. For purposes of the Lithium Valley Economic Opportunity Investment Plan this shall be defined as the process by which the County of Imperial controls its economic future as it relates to lithium/rare mineral extraction, processing, manufacturing and renewable energy generation and storage through specific actions that will be taken with intention and transparency. Specific Actions of the County of Imperial 1. Board of Supervisors adopting a Resolution in support of the Lithium Valley Economic Opportunity Investment Plan. 2. Board of Supervisors creating a subcommittee known as the Lithium Valley Economic Opportunity Investment Plan Subcommittee comprised of two (2) members of the Board of Supervisors.3. Creation of an internal working group to the County Board of Supervisors to include:

Lithium Valley Subcommittee (2 persons of the Board of Supervisors) County Executive Officer
County Counsel
County Director of Planning and Development Services
County Director of Intergovernmental Relations
Contract Economist/Economic Development Consultant to the County.

4. County of Imperial seeking voter approval to establish appropriate remuneration for lithium/rare mineral mining and power generation/storage to provide appropriate financial benefits to the County (as a municipal corporation) and community organizations that further the economic interests of the region.

Said remuneration shall be used to address environmental impacts of industry and infrastructure improvements. The remuneration vehicle shall provide tax credits for lithium/rare mineral extraction used within Imperial County for mid-stream processes (may include but not be limited to processing and manufacturing).

5. County of Imperial establishing a Lithium Valley Project Ombudsperson to work directly with economic investors seeking to engage in lithium/rare-mineral mining and renewable energy generation to provide enhanced communication by and between internal departments to the County as well as assistance in communication with State and Federal Agencies.

6. County of Imperial exploring economic viability of an Enhanced Infrastructure Finance District (EIFD) to finance infrastructure improvements.

7. County of Imperial providing leadership (Subcommittee of the Board of Supervisors) and professional staff resources for which to locally implement the specific actions requested of the State of California and the United States Federal Government, including the following:

Assist State and local agencies in the development, construction and operation of a California Polytechnic University or similar institution to provide education and training in support of lithium/raremineral mining and renewable energy generation. Specific Actions Requested of the State of California Governor Newsom identified Lithium Valley in remarks on his fiscal year 2022-23 proposed budget, The California Blueprint which was released on January 10, 2022. “We have what someone described as the Saudi Arabia of lithium right here in the state of California down in Imperial County near the Salton Sea,” Newson remarked. Imperial County agrees with the Governor’s assessment and Lithium Valley can produce these valuable resources in an environmentally-conscious way. Each proposed lithium extraction plant would be a closed-loop system, without the creation of open pits or solar evaporation ponds.

California and the United States can secure a strategic mineral resource and promoted environmentallyfriendly business practices. Delegating pplanning and permitting authority of Geothermal Development up to 99.9 Megawatts generation, to the County of Imperial. (Currently limited to 49.9 Megawatts) Currently, Imperial County is authorized to permit Geothermal Power Plants that generate up to 49.9 MWs, and a developer wishing to construct a Geothermal Power Plant 50MWs or larger is required to follow the California Energy Commission’s (“CEC”) Application for Certification Process (“AFC”). However, the CEC’s Small Power Plant Exemption Program (“SPPE”) allows for a proposed Thermal Power Plant project to be exempted from the AFC when: 1) the project will generate between 50 and 100 MWs; and 2) the CEC has made a determination that the project will not have a significant effect on the environment or energy resources. Imperial County is respectfully requesting that the (“CEC”) grant our County the ability to permit Geothermal Power Plants up to the maximum 99.9 MWs in accordance with the SPPE.

Further, formally change the definition of “net-to-grid” to provide opportunity for energy generation facilities in Imperial County to deliver power to themselves (parasitic load), adjacent users (affiliated and non-affiliated) and micro-grid users (affiliated and non-affiliated) within five (5) miles of the boundaries of the host site. Host site shall be defined as the parcel at which the power generation facility is located (or all parcels if facility is located on multiple parcels). When said changes are granted by the State of California, it will kick start both the development of mineral recovery and increase the State baseload renewable power portfolio. Provide Direct Funding to Imperial County for the Lithium Valley Specific Plan and rogrammatic Environmental Impact Report ($5,000,000) to be available within 30 days of adoption of the FY 2022-23 State Budget The Lithium Valley Specific Plan and Program EIR seeks to help meet the State of California’s renewable energy production goals, while providing Industry with a clear timeline for project delivery. The Specific Plan’s goal is built upon this effort, expanding the development opportunities, both in additional geothermal energy production along with mineral recovery, hydrogen, biofuels, and renewable (cathode, battery, electric vehicle) manufacturing facilities. The Program EIR ensures consideration of CEQA requirements and environmental impacts on a large project area plus avoids duplication of individual project CEQA reviews. There are a number of other sectors of the renewability that the Salton Sea Resource has the potential to develop. This includes: 1) creating environmentally safe and renewable mineral recovery through geothermal brine, 2) developing other sustainable fuels such as green hydrogen and bio-based fuels, and 3) recycling and reusing Lithium Valley Economic Opportunity Investment Plan (Imperial County LVIP) organic (plant based) and inorganic mineral waste (battery recovery), both diverting from landfills and reducing the depletion of raw materials. Imperial County released a Specific Plan and Programmatic Environmental Impact Report (EIR) Request for Proposals on January 13, 2022.

The responses will be brought to the Imperial County Board of Supervisors in March 2022, with a recommendation to award. We are seeking support and funding of the Lithium Valley Specific Plan and Program EIR, with an estimated cost of $5 million to be made directly available to the County of Imperial within 30 days of adoption of the FY 2022-23 State of California Budget. Direct Funding to the County of Imperial for the Lithium Valley Development Office ($500,000 annually, increasing by 5% per annum) for a period of ten (10 years) beginning with the FY 2022-23 State Budget Imperial County is seeking support and funding of a Lithium Valley Development Office, located in Imperial County. 41/46
051022AGN
The office function will be to provide direct feedback to the development on project status and shepherd projects through the County of Imperial permitting and planning offices. In addition, the office will follow the Lithium Valley Specific Plan and Program EIR, answer Industry inquiries, and encourage ancillary business development in Lithium Valley. The Lithium Valley Development Office will include an economic development officer, civil engineer, planner and analyst. Each position would be limited term and compensated at 30% greater than the current corresponding County pay structure. The team will report to the Imperial County Board of Supervisors and provide collaboration reports to the California Energy Commission, Lithium Valley Commission and Governor’s Office of Economic Development (GOBIZ).

The estimated cost is $500,000 annually (increasing by 5% per annum) and would be for a term of ten (10) years, between July 1, 2022, and June 30, 2031. State of California Support and Assistance in creation of an Imperial County Severance Tax or Resource Levy for critical minerals (delegated authority to Imperial County) In November 2022, the County of Imperial shall seek voter approval to establish appropriate remuneration for lithium/rare mineral mining and power generation/storage to provide appropriate financial benefits to the County (as a municipal corporation) and community organizations that further the economic interests of the region. The State of California shall support this self-determination effort so that the County of Imperial and its residents will directly benefit from the production of lithium/rare minerals and renewable energy resources being exported elsewhere in California, the nation and internationally. A mineral tax/levy/fee would be directed to infrastructure, environmental mitigation, and community enhancement, all within Imperial County. Infrastructure needs are being identified by Imperial County Public Works and the Lithium Valley Specific Plan. Already, Imperial County has invested in the repair and reopening of two (2) critical bridges that serve the Lithium Valley Area. As the Salton Sea recedes, additional Geothermal resources and mineral extraction sites will need road and utility connection. A guaranteed revenue allows Imperial County to make the improvements, as industry demands grow.

Environmental mitigation needs are found at the South Salton Sea. Air pollution dust control projects, wetlands, remediation, land reclamation, and tree planting are some of the measures available. These projects would be on land around or near the Lithium Valley area. Lithium Valley Economic Opportunity Investment Plan (Imperial County LVIP) Community enhancement needs are items that make our neighborhoods alive. Imperial County, in partnership with the Cities and Special Districts within the County would begin investment in cultural projects, music, art, parks and education endowment.

Celebrating the contributions of our diverse community and encouraging some of the new workforce to locate in our communities. The State of California will work cooperatively with the County of Imperial relative to any fee/taxation being discussed by State officials in an effort to ensure that such fees/taxes combined with local fees/taxes (for the benefit of the host community/region) do not place an undue burden on the industry, thus making lithium/rare mineral extraction and geothermal energy generation unfeasible.

Support and Funding of a Cal-Poly campus in Imperial County ($100 million) or Expansion of Current/Past Efforts (including cooperatives with UC Riverside and UC Davis to include educational opportunities in engineering, geology and chemistry for which to train/support the lithium industry in Imperial County) Imperial County requests the support and funding of a California Polytechnical University in Lithium Valley. A Cal Poly campus would provide the engineers and chemists needed to work in the geothermal and lithium development sector; as well as any co-locating cathode or battery company workforce needs.

The polytechnical college provides opportunities for the vocational and technical development of the workforce as well, plus it would complement the need for supporting our continuing agricultural business.

As an immediate action, the State of California would establish a Cal-Poly extension at the three hundred (300) acres site in Brawley, California. The property was previously donated by a local businessperson with the hopes that a full four-year university would be established. The site has some superstructures, though is currently vacant. The on-site buildings could be remodeled and re-opened to immediately establish a CalPoly extension on this land with temporary classrooms/laboratories while a full campus is designed and constructed. The need is immediate. Support and Provide Seed-Funding a Reference Lab for Lithium Purity Testing The value and use applicability of metals, minerals and other elements rely on their laboratorytested purity. Laboratory facilities must be located at or near actual mining facilities for quality control purposes. As the host community for lithium extraction, the Imperial Valley must have appropriate testing facilities to ultimately benefit commercial and consumer applications of lithium and other rare-earth minerals. Such a facility could be run as a cooperative serving many different extraction operations and (ultimately) be paid for out of a remuneration tax or fee. Go-Biz Tax Credit Carve-Out for Lithium, Geothermal The County of Imperial requests that the State of California dedicate $5,000,000 annually for new Employment Tax Credits for employers within appropriate NAICS codes making new investments of 42/46
051022AGN
lithium/rare-mineral mining in Imperial County for a period of five (5) years (time period of FY 2024 through FY 2028). This carve-out would provide the impetus for lithium/rare-mineral mining/processing/manufacturing and geothermal energy generation to begin immediately to meet the market demands and thus providing for supply-chain and environmental benefits to the State of California sooner. Executive Order or Legislative Action exempting lithium/raremineral and geothermal producers from additional compliance from CEQA after PEIR and SP The County of Imperial requests that the State of California take an executive or legislative action that results in the exclusion of current and future projects that are within the County’s (to be created) Specific Plan and Lithium Valley Economic Opportunity Investment Plan (Imperial County LVIP) Page 7 of 8 Programmatic Environmental Impact Report from further environmental review, such as the California Environmental Quality Act (CEQA). Specific Actions Requested of the United States Federal Government The United States Department of Energy (U.S. energy Secretary Granholm) produced the National Blueprint for Lithium Batteries (released in June 2021). It outlined the need for lithium production as a means of propelling the United States economy and providing for environmental improvements. It quotes President Biden’s Executive Order 14008 “Tackling the Climate Crisis Home and Abroad” (1/27/21).

Lithium/rare-mineral mining and renewable energy generation domestically helps reduce American reliance on foreign sources for needed manufacturing inputs and energy production. The Infrastructure Investment and Jobs Act of 2021 provides $1.2 trillion of future spending from the United States Federal Government on various programs and projects. Included in this is about $550 billion of direct spending on infrastructure projects. Imperial County’s Lithium Valley Economic Opportunity Investment Plan needs the direct involvement and investment from the Federal Government. The Infrastructure Bill included future spending in the following categories that can be used to propel the Lithium Valley Economic Opportunity Investment Plan: Roads & Bridges: $157 billion Railways: $66 billion Electrical Grid: $65 billion Environmental Remediation: $21 billion Portions of the Infrastructure Bill can be utilized to help propel investment in lithium/rare-mineral mining and renewable energy generation in Imperial County: Roads & Bridges ($157 billion): Imperial County needs an allocation of $50 million to provide for road and bridge infrastructure to portions of the region where lithium/rare-mineral mining and renewable power generation occur. This will provide the opportunity for increased access in a safe manner for production equipment and construction/operational personnel. Railways ($66 billion): An estimated 15,000,000 tons of lithium will be extracted over a 50+ year period (Upstream). Some of this material will be used directly in midstream (material processing, and cell manufacturing). Ultimately almost all either upstream or midstream material/products will be exported out of Imperial County to end-users. Rail is an efficient and effective means to move these materials and goods. Imperial County needs $1 billion of railway upgrades in the form of additional tracks, loading and siding/spur infrastructure. Electrical Grid ($65 billion): The process of lithium and rare-mineral extraction (in the case of Imperial County) also generates significant geothermal (baseload) power. Energy production is reliant on transmission and distribution. Expanded capacity is needed to move energy from Imperial Valley to more populous areas throughout California and the Western United States. Imperial County requests $500 million in funding offsets for grid upgrades and wheeling charges from energy producers. Lithium Valley Economic Opportunity Investment Plan (Imperial County LVIP) Environmental Remediation ($21 billion): Lithium battery production will (ultimately) generate an issue at the back end, “End-of-life recycling and reuse”.

Without significant advanced planning and investment, this will become an immense environmental issue for generations to come. The Federal Government has the opportunity to utilize funds from the Infrastructure Bill to invest in appropriate facilities for “End of Life Recycling and Reuse.” Imperial County believes such activities should occur where (or near) the lithium was originally mined and processed. The Federal Government should allocate up to $500 million in direct funding and/or loan guarantees for companies that desire to build/operate End of Life Recycling and Reuse facilities in Imperial County to support the lithium battery and technology industry. Call to Action The Lithium Valley Economic Opportunity Investment Plan will create billions of dollars of private economic investment in Imperial County producing lithium/rare-minerals and renewable energy helping propel the United States economy for generations. This will result in employment opportunities for residents of the region and tax revenue at the local, state and federal government. The success of the Lithium Valley Economic Opportunity Investment Plan relies on the adoption and funding of the Plan at all levels of government (County, State and Federal). The actions needed by each level of government are outlined quantitively within the plan. It is incumbent on each participant to take immediate action on their portion of the plan in order to achieve the desired outcome for economic investment. 43/46

RE: Support for Imperial County’s Lithium Valley Economic Opportunity Investment Plan Dear Governor Newsom:

On behalf of City of Calipatria, I’m writing to share with you our support of Imperial County’s Lithium Valley Economic Opportunity Investment Plan.

Imperial County includes several disadvantaged communities and is one of the poorest counties in the state.

We believe this proposal, among other efforts, enables an efficient, secure and fair development of an industry that has the potential to propel and improve the economic and environmental future of Imperial County residents for generations to come.

In order to ensure we create the environment necessary to realize the massive potential for the County, California, and the nation, we need to be both thoughtful and aggressive in our development of this opportunity. That is why the Imperial County Board of Supervisors has adopted the Lithium Valley Economic Opportunity Investment Plan. This plan articulates the local, statewide, and national benefits of this endeavor. It also prescribes the specific activities we believe are necessary for the County, the State, and the Federal governments to undertake in order to best capitalize on those benefits.

Given the critical nature of this endeavor, we strongly urge you to do everything you can to help Imperial County make this plan a reality. We greatly appreciate your time and attention. If you have any questions, please contact Romualdo Medina, City Manager-760-348-4141.

RE: Support for Imperial County’s Lithium Valley Economic Opportunity Investment Plan; and Development of Lithium Valley Disadvantaged Communities Economic Development Plan As one of several disadvantaged communities in Imperial County, the City of Calipatria supports Imperial County’s Lithium Valley Economic Opportunity Investment Plan (“Plan”). The citizens of Calipatria believe that the Plan, along with additional efforts requested in this letter, will enable an efficient, secure, 44/46
051022AGN
and fair development of an industry that has the potential to propel and improve the economic future of Calipatria residents for generations to come, but it also has the potential to severely impact the natural and built environment in and around the incorporated boundaries of Calipatria.

The City of Calipatria will be the most impacted municipality due to its close proximity to the Lithium Valley Area. The City of Calipatria is located in the northeastern end of the Imperial Valley, contiguous to the Salton Sea Known Geothermal Resource Area. It is 40 miles north of the US-Mexico border, 96 miles east of San Diego, and 142 miles southeast of Los Angeles. The City of Calipatria’s population is 6,515 (April 1, 2020) which includes a prison population of approximately 3,000 in Calipatria State Prison (Census 2020). Currently, the city’s population is at a decline of -4.46% annually and has decreased by -

15.56% since 2010. The City of Calipatria and Imperial County has among the lowest poverty rates in the nation. Persons in poverty in 2016-2020 for the City of Calipatria was 35.4% compared to Imperial County at 18.1% and State of California at 12.58%. The City’s median household income (in 2020 dollars) was $37,196, compared to County $46,220 and State $80,440.

Aware of our economic challenges as a disadvantaged community, the City of Calipatria has taken a proactive and strategic approach to apply our community’s unique economic role and assets to help facilitate the momentum of the development of the Lithium Valley project. The City has been actively involved in workshops, meetings, forums, and visits relating to the Lithium Valley project to better assess how we can better support this project. Recent investments undertaken by the City include the sale of cityowned land to facilitate the construction of 130 single-family homes, street improvements, a new park with a 12,655 community center, and wastewater collection system improvements. The City also has several shovel-ready projects that will help mitigate some of the potential environmental impacts from increased production. These include City Entrance Signs, Active Transportation and Safe Routes to School Pedestrian Improvements, State Highway 111 ADA Improvements and Beautification Project, and Sewer Line Replacement Project, all with complete studies pending funding.

The City of Calipatria welcomes the economic and global environmental benefits this Lithium Valley Industry will bring to our municipality, County and State, and to the Nation’s energy security. The Calipatria Lithium Valley Disadvantaged Communities Economic Development Plan will lay the foundation to direct our efforts and place-based assets and location advantages to the success of the Lithium Valley project. It will follow a structural sequence of phases and specific tasks that is data driven, identify and inclusive engagement of all stakeholders, and assessment of the economic opportunities for our City and immediate impacted area
The Imperial County Lithium Valley Economic Opportunity Investment Plan outlines the local, statewide, and national benefits of local lithium extraction. It also prescribes the specific activities we believe are necessary for the County, the State, and the Federal governments to undertake in order to best capitalize on those benefits. We strongly urge you to do everything you can to help Imperial County make this plan a reality.

The City of Calipatria also respectfully requests that you develop a Lithium Valley Disadvantaged Communities Plan with an inclusive community engagement process targeting the immediately impacted communities burdened by the increased operational activity, pollution, required public services, infrastructure, poverty, and potential annexation. The plan should follow the State of California Clean Energy of 2018 as well as the Federal Government Green Act of 2021, including but not limited to the following areas of investment categories and goals for the minimum level of investment for disadvantaged communities:
· Five-year clean energy investment plan provided to the California legislature for approval. · California Budget appropriations for green and clean energy similar as the ‘cap and trade’ program under AB 32 and in compliance with the Go Biz tax credit program. · Environmental Impact Report specifically to the Lithium Valley and Salton Sea Geothermal Basin area.
· Maximize economic, environmental, and public health benefits to the Calipatria and Niland communities, particularly from the Salton Sea receding shoreline 45/46
051022AGN
· Foster job creation by promoting local impacted communities within the Lithium Valley and Geothermal Basin Area.
· Complement efforts and increased funding to improve air quality to the impacted communities. · Direct investment toward the most immediately impacted disadvantaged communities and households within the redline community of Calipatria and Niland of the Lithium Valley project. · Provide opportunities for business, public agencies, nonprofits, and other community institutions to participate in and benefit from statewide and national efforts to promote green clean energy. · Infrastructure funding for State Highway 111 improvements, local street improvements, acquisition of the water system, sewer, public safety, and services for the redlined communities of Calipatria and Niland · Educational funding assistance to locally impacted Calipatria Unified School District, Imperial Valley College, and funding assistance for a higher institution of learning specializing in minerals and green energy curriculum and degrees, such as University of California Berkeley, Cal Poly, State Universities, and others.
· Quality control funding for the lithium extraction and mining testing within the Lithium Valley project.
· Funding for the Calipatria and Niland Impact Severance Tax for the immediate impacts on infrastructure, job training, community enhancements, and environmental mitigation. · Funding for increased and improved medical services to our local hospitals, including a children’s hospital.
• Immediate funding for Calipatria State Prison wastewater collection system improvements.

As Mayor of the City of Calipatria and speaking on behalf of our directly impacted disadvantaged community, I respectfully deliver this request in an effort to be included in the State of California’s green energy community investment plan for green and clean energy. We support the direction the State of California is taking to address green-house emissions and lead the way with new clean energy industries.

We look forward to a successful Lithium Valley extraction and battery manufacturing industry, as well as the investment partnership this area critically deserves. We greatly appreciate your time and attention. If you have any questions please contact Rom Medina, City of Calipatria City Manager 760) 348-4141 x3.
