The proposed water well site is at 17902 Bushard Street in the City of Fountain Valley (Fountain Valley). As part of the MOU, Newport Beach's role was to lead the project planning, design and construction efforts. For the City Council's consideration is a water well permit and an encroachment agreement with Fountain Valley to secure compliance with the local permitting authority and a Resolution of Intention, which will allow early project costs to be reimbursable via bond financing if pursued by the Newport Beach. RECOMMENDATIONS: a) Find this project exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15332 (Class 32, In -Fill Exemption) of Title 14 of the California Code of Regulations (14 CCR § 15332) (Class 32 exemptions are for projects of certain criteria on a development site of five acres or less) of the CEQA Guidelines, because this project has no potential to have a significant effect on the environment; b) Approve a Water Well Permit and Encroachment Agreement with the City of Fountain Valley and Laguna Beach County Water District for the construction, operation and maintenance of a new municipal water well facility at 17902 Bushard Street; and c) Adopt Resolution No. 2025-76, A Resolution of the City Council of the City of Newport Beach, California, Regarding Its Intention to Issue Tax -Exempt Obligations, if needed. DISCUSSION: An additional water well for the City's water system has been a long-term goal to improve water reliability, redundancy and local control over the City's water needs. The 2019 Water Master Plan reinforced the need and incorporated it into the 30-year plan. Water supply reliability and local control are key tenets of a well -run water system. 4-1 Water Well Permit and Encroachment Agreement with the City of Fountain Valley; and Resolution No. 2025-76: Declaration of Intent to Issue Tax -Exempt Obligations (Bonds) November 4, 2025 Page 2 Newport Beach is a member of the Orange County groundwater basin, which is managed by the Orange County Water District (OCWD). The groundwater basin is strategically managed to maximize local water resources, enhance water reliability, ensure high -quality water, prevent seawater intrusion and protect Orange County's water rights. The region's imported water supplies - from Northern California and the Colorado River - have become less available and more restricted. For the foreseeable future, groundwater is the best path toward ensuring the City's water reliability. On September 24, 2024, the City Council approved an MOU with Laguna Beach and a technical memorandum prepared by the Utilities Department regarding a new water well site at 17902 Bushard Street in Fountain Valley. Newport Beach and Laguna Beach staff believe the Bushard Street site is a viable groundwater location and will significantly improve both agencies' groundwater capacity, even in a shared configuration. The Bushard Street site is situated in a highly productive location within the groundwater basin and is approximately 1,700 feet away from Newport Beach's main 36-inch water transmission line, two key factors for a viable site. Staff from both agencies developed an MOU outlining the roles and responsibilities of each agency. In general, the MOU states that each agency is interested in a partnership and will work on separate project tasks, ultimately moving toward a formal partnership. With Newport Beach's long history and experience in the development and operation of the existing water wells, our responsibility was to lead the preliminary design, land use entitlements, and environmental efforts. Over the last year, Public Works and Utilities Department staff prepared the preliminary project design and have secured the final project entitlements. The key components of the entitlements are the environmental review, (which is explained in the Environmental Review section of the staff report) and the permit/agreement with Fountain Valley. Per Fountain Valley Municipal Code (FVMC) Section 14.16.040, a well that is intended to transport water outside their city limits must be in the public interest and requires a City Council approved agreement. Cooperatively, staff from all agencies developed the attached Water Well Permit and Encroachment Agreement (Agreement) (Attachment A); which satisfies the Fountain Valley's Municipal Code requirements. It also preserves Fountain Valley's primary rights -of -way, assigns all maintenance to Newport Beach, and secures public benefit/mitigation payments and in -kind improvements. The Agreement provides the following public interest benefits to Fountain Valley: $82,000 one-time mitigation payment for lost permit revenue; a $10,000 annual public benefit payment for property tax loss; a $45,000 one-time payment towards all encroachment and inspection fees; $100,000 one-time public benefit payment toward Fountain Valley public safety or future water/well projects; a system interconnect stub -out for a future Fountain Valley -built interconnection; and a Newport Beach constructed, Fountain Valley owned and operated water main from La Amapola Circle to Bushard Street with an easement. Newport Beach and Laguna Beach staff believed these shared costs to be reasonable in securing the project entitlement and permits. Further details are available in the Fountain Valley Staff report (Attachment B). 4-2 Water Well Permit and Encroachment Agreement with the City of Fountain Valley; and Resolution No. 2025-76: Declaration of Intent to Issue Tax -Exempt Obligations (Bonds) November 4, 2025 Page 3 With the entitlement approved, staff will continue to complete the final designs and move towards construction. Staff estimates the overall project completion (i.e. produced water) will be in 2028. Similar to the previous 1990's well(s) project, staff is designing and will build the project in three phases: drilling the well, expected to start in late 2026; pump house and site development, expected to start in 2027; and the water transmission pipeline, expected to start in 2027. Also, in first quarter of 2026, staff will return with the formal Laguna Beach partnership agreement. This agreement will formalize the ownership, the well production capacity rights, the operation of the well and all funding. FISCAL IMPACT: The adopted budget includes sufficient funding for this agreement and the ongoing project development. Funding will be provided from the Water Enterprise Fund and expensed to the Public Works Department Capital Improvement Program, Project 24W13, which has a current budget allocation of $1.5 million. The preliminary cost estimate for the overall project is approximately $30 million, of which Newport Beach's share is expected to be $20 million. The value of groundwater is significant compared to imported water purchased from the Metropolitan Water District ($711 per acre-foot versus $1,395 per acre-foot). Even after accounting for maintenance, pumping, electricity, treatment, and asset depreciation, water produced from this well is expected to generate annual cost savings. Staff is preparing a comprehensive multi -source funding plan, which will be presented to the City Council in 2026. The plan will include a combination of set -aside water capital funds (pay-as-you-go funding derived from water rates), use of Water Fund reserves, and payments from the City of Laguna Beach. It will also include consideration of a low - interest loan from the OCWD and/or a debt financing issuance. OCWD has established a low -interest loan program to incentivize local water producers to develop new wells, and City staff has submitted a Notice of Intent to participate. If the program remains available at the time of construction, staff will continue to pursue this financing opportunity. Staff also believes bond financing to be a viable alternative and has prepared a Resolution of Intention (Attachment C). Adoption of this resolution does not commit the Newport Beach to debt financing; however, it preserves Newport Beach's ability to reimburse early project costs should bond financing ultimately be pursued. Although grant funding for this type of project is uncommon, staff has actively pursued such opportunities with limited success. Other potential funding options include deferring existing Water Capital Improvement Program projects or increasing water rates; however, these alternatives are not recommended at this time. 4-3 Water Well Permit and Encroachment Agreement with the City of Fountain Valley; and Resolution No. 2025-76: Declaration of Intent to Issue Tax -Exempt Obligations (Bonds) November 4, 2025 Page 4 ENVIRONMENTAL REVIEW: Staff recommends the City Council find this project exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15332 (Class 32, In -Fill Exemption) of Title 14 of the California Code of Regulations (14 CCR § 15332) because it has no potential to have a significant effect on the environment. Section 15332 (Class 32, In -Fill Exemption) of Title 14 of the California Code of Regulations (14 CCR § 15332) — Class 32 exemptions are for projects that are proposed on a development site of five acres or less. To qualify for this exemption, the project must be consistent with the general plan and zoning; shall be on a project site that is five acres or less within an incorporated city; the site does not contain habitat for endangered, rare or threatened species; the project would not result in any significant effects relating to traffic, noise, air quality, or water quality; and the site can be adequately served by all required utilities and public services. Staff prepared a full analysis of the project's compliance with the Class 32 CEQA exemption (Attachment D) and found that the project meets the qualifications for the exemption. Furthermore, the project does not meet any of the exceptions outlined in Section 15300.2 of the CEQA Guidelines that would disqualify the exemption. Section 21080(b) of the California Public Resources Code (PRC § 21080(b)) and CEQA Guideline Sections 15268 and 15300.1 (14 CCR § 15268 and 14 CCR § 15300.1) —These sections provide statutory and categorical exemption for ministerial projects. Fountain Valley regulates water well permits through Chapter 8.12 (Construction and Abandonment of Wells) of the Municipal Code. Section 8.12.045 (Permit issuance/denial) provides that the well permit shall be issued if it meets the criteria provided in that section. Likewise, permits are issued for the related work in the public right-of-way provided the work complies with code. Inasmuch as the Fountain Valley does not exercise discretion when issuing these permits, the project is classified as ministerial and qualifies for the statutory and categorical exemption for ministerial project. NOTICING: The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at which the City Council considers the item).

Three -Year Strategic Goals ❑x Enhance the culture and environment of "A Nice Place to Live" ❑x Achieve fiscal stability by evaluating processes, and attract and retain revenue producing businesses/opportunities ❑ Attract and retain quality staff through best practices and trends ❑x Maintain, build, and modernize infrastructure to support growth and future needs of the City ❑ Not applicable EXECUTIVE SUMMARY: The City of Newport Beach (Newport Beach) and Laguna Beach County Water District (LBCWD) plan to develop a groundwater production facility at LBCWD-owned property located at 17902 Bushard Street in the City of Fountain Valley (Fountain Valley). LBCWD and Newport Beach have entered into a separate, standalone Memorandum of Understanding establishing a framework for collaboration on the use of the property for a new water well facility that would supply groundwater from the Orange County Ground Water Basin to LBCWD's and Newport Beach's water customers. LBCWD owns the property, and Newport Beach will construct and operate the well sites and has taken the lead on the agreement with Fountain Valley. Per Fountain Valley Municipal Code (FVMC) Section 14.16.040, a well that is intended to transport water outside city limits must be in the public interest and requires a City Council approved agreement. The Water Well Permit and Encroachment Agreement (Agreement) satisfies the FVMC requirements, as it preserves Fountain Valley's primary rights -of -way, assigns all maintenance to Newport Beach, and secures public benefit/mitigation payments and in -kind improvements. The Agreement provides the following public interest benefits to Fountain Valley: 4-17 1. $82,000 one-time mitigation payment; 2. $10,000 annual public benefit payment (CPI adjusted and compounded annually); 3. $45,000 one-time payment towards encroachment and inspection fees; 4. $100,000 one-time public benefit payment toward Fountain Valley public safety or future water/well projects; 5. A System Interconnect stub -out for a future Fountain Valley -built interconnection; and 6. A Newport Beach constructed, Fountain Valley owned and operated 8-inch C900 main from La Amapola Circle to Bushard Street with easement. DISCUSSION: The proposed Agreement lets Newport Beach and LBCWD drill two groundwater wells at the LBCWD owned property located at 17902 Bushard Street in Fountain Valley. It allows water lines in Bushard Street and Talbert Avenue to run in Fountain Valley's rights -of -way. Because the wells will send water outside of Fountain Valley, FVMC Section 14.16.040 requires a City Council approved agreement and that the project is in the interest of the public. Fountain Valley keeps full authority to work on and in the streets. If Fountain Valley needs to work on or in the streets, it may do so. Newport Beach must restore everything to its prior condition and is responsible for the maintenance of the property. Newport Beach will build, operate, and maintain the wells, pipelines, walls, and storm drain, and LBCWD, as the owner of the property, will provide access for the same. Fountain Valley will not pay for maintenance. The Agreement requires Newport Beach and LBCWD to carry $2,000,000 per occurrence and $4,000,000 aggregate in liability insurance, and also requires Newport Beach and LBCWD to fully indemnify Fountain Valley and name the City of Fountain Valley as an Additional Insured under the policy. Before permits are issued, Newport Beach must submit a stormwater flow sufficiency report and if the City Engineer determines that the Bushard/Talbert lines need upsizing to handle the project's flow, Newport Beach will build those upgrades at its sole cost and expense. This ensures that Fountain Valley will not incur any costs for storm drain upgrades. Staff recommends the Council find that this Agreement is in the public interest per the standards set in FVMC Section 14.16.040. It preserves the Fountain Valley's rights -of -way, places all construction and liability on Newport Beach, and secures the following benefits to Fountain Valley: 1. $82,000 one-time payment for mitigation of potential lost revenue in permits, plan checks, and fees; 2. $10,000 annual public benefit payment (CPI adjusted and compounded annually) for the loss of potential property tax revenue; 3. $45,000 one-time payment towards encroachment into the rights -of -way to include the placement of the water main, storm drain, and all curb, gutter, and sidewalk improvements; 4-18 4. $100,000 one-time public benefit payment toward Fountain Valley public safety or future water/well projects; 5. A System Interconnect stub -out for a future Fountain Valley -built interconnection for emergency use; and 6. A Newport Beach constructed, Fountain Valley owned, 8-inch C900 main from La Amapola Circle to Bushard Street with easement, at no cost to Fountain Valley, for the Fountain Valley water system to improve water quality and system redundancy. FISCAL REVIEW: The Agreement yields a net positive fiscal impact for Fountain Valley. It secures a one-time revenue of $82,000 mitigation payment, a one-time $45,000 payment towards encroachment and inspection fees, and a one-time $100,000 public benefit payment, plus an annual $10,000 public benefit payment (CPI adjusted and compounded annually). In addition, Newport Beach will construct an 8-inch C900 main (La Amapola to Bushard) and grant an easement (in kind improvements), and will provide a System Interconnect emergency stub out for a future Fountain Valley built tie in. PUBLIC NOTIFICATION: Notification was made through the regular agenda process. ENVIRONMENTAL IMPACT REVIEW: Under the California Environmental Qualification Act ("CEQA"), Newport Beach is the Lead Agency for the physical construction of the two wells and related facilities. Newport Beach will circulate and adopt appropriate CEQA documents prior to issuing a construction notice to proceed. ATTORNEY REVIEW: The Attorneys for the City have reviewed and approved the Agreement. ALTERNATIVES: Alternative No. 1: Approve the Water Well Permit and Encroachment Agreement between the City of Fountain Valley, the City of Newport Beach, and the Laguna Beach County Water District for the construction, operation, and maintenance of two municipal production wells and associated facilities at 17902 Bushard Street. Alternative No. 2: Do not approve the Water Well Permit and Encroachment Agreement. RECOMMENDATION: 4-19 Staff is requesting City Council approval of Alternative No. 1 to approve the Water Well Permit and Encroachment Agreement between the City of Fountain Valley, the City of Newport Beach, and the Laguna Beach County Water District for the construction, operation, and maintenance of two municipal production wells and associated facilities at 17902 Bushard Street.

These are referred to as "categorical exemptions." The categorical exemptions include an urban infill exemption designed to streamline development in already -developed urban areas. This report is intended to determine if the Proposed Project meets the provisions to be categorically exempt from CEQA per State CEQA Guidelines 15332 (Class 32 - In - fill Development Projects). The following criteria must be met for a project to be characterized as in -fill development: a. The project is consistent with the applicable general plan designation and 4-26 all applicable general plan policies as well as with applicable zoning designation and regulations. b. The project is in the City on a site less than five acres and is substantially surrounded by urban uses. c. The Project Site has no value as habitat for endangered, rare or threatened species. d. Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality. e. The site can be adequately served by all required utilities and public services. This evaluation was prepared to determine whether the Proposed Project qualifies for the class 32 in -fill development exemption. This evaluation is supported by the attached technical appendices. SURROUNDING LAND USES AND SETTING: The Proposed Project would be constructed on a 31,929 square foot site at 17902 Bushard Street (APN 167-271-34) in the City of Fountain Valley (City), Orange County, California (see Figure 1 - Regional Vicinity Map). The Project Site is located on the east side of Bushard Street, approximately 280 feet north of Talbert Avenue. The Project Site is currently vacant but was previously improved with a single-family house and small commercial landscape nursery. Surrounding use includes single- family residences on the north, east, and south sides of the site (Figure 2 - Site Location - Aerial View Map). Further north, beyond the single-family residences, is Fountain Valley High School. West of the project site, across Bushard Street, is a multi -family senior apartment development and the Fountain Valley Senior Center. The Project Site has a Fountain Valley General Plan (FVGP) land use designation of Low Density Residential and is zoned R-1 Single Family Residential (see Figure 3 - General Plan Land Use Designation Map and Figure 4 - Zoning District Map). The Project Site is located within the United States Geological Survey (USGS) 2022 Newport Beach, California 7.5-minute, 24000 topographic quadrangle. The Project Site is also located within FEMA Flood Plain Panel 06059CO254J and is designated within Zone X, which is described as an "area with reduced flood risk due to levee"'. The Project Site is not located within any fire hazard severity zones (see Figure 5 -Fire Hazard Severity Zone Map).

Fire Hazard Severity Zone Map PROJECT DESCRIPTION: The Proposed Project consists of the construction two water wells to an approximate depth of 700 feet and 300 feet. Once completed, the water wells will be connected to the City of Newport's existing water mains located in the Talbert Channel. Specifically, the Proposed Project will include the following: • Construction of the two water wells, one to an approximate depth of 700 feet and the other to an approximate depth of 300 feet. The wells are approximately 75 feet apart and will be drilled consecutively. • Upon completion of each well, the well will be connected to a turbine pump and related appurtenances. This will include pipeline stub out for a future system interconnect adjacent to the groundwater production facility. The system interconnection would allow Fountain Valley access to water produced by the Newport Beach wells in the event of an emergency that disrupts Fountain Valley's water service. • Both wells and related equipment will be housed within a 2,400 square foot structure that is 15 feet tall. The building is proposed to be located near the western portion of the site, setback 20 feet from the Bushard Street right-of- way. The building will also be setback 45.58 feet from the north property line, 48.41 feet from the south property line, 78.55 feet from the east property line, and 64 feet from the La Amapola Circle right-of-way. 4-30 • A new 24-inch water main will be provided to connect the two wells to the existing Newport Beach water main that is located within the Talbert Channel. The new 24-inch water main will traverse from the site, south within the Bushard Street right-of-way, thence west in the Talbert Avenue right-of- way, finally connecting to the existing water main within the Talbert Channel. • An 8-foot-tall concrete masonry block wall to be constructed along the property boundaries, which will include two 20-foot-wide sliding gates to provide access to the Property from Bushard Street. • Approximately 5,368 square feet of landscaping will be provided along the north, south, and east property lines. The remainder of the site will be improved with asphalt paving. • An 18-inch reinforced concrete storm drain will connect from a drain box adjacent to each of the water well, through the Bushard Street right-of-way, to the existing storm drain in Talbert Avenue. • An 8-inch C900 water main that connects the 8-inch Asbestos Cement water main on La Amapola Circle to the 8-inch Asbestos Cement water main on Bushard Street with isolating gate valves at each end of the tie-in will be provided. This water main will not connect to the wells, but rather will provide a loop connection for the City of Fountain Valley's water supply system. • The site will be connected to electrical power through an underground connection from the nearest utility pole on Bushard Street. A transformer will be located near the northeast corner of site. An emergency generator will be located on the east side of the building. • In the unlikely event per- and polyfluoroalkyl substances (PFAs) are found in the groundwater, additional filtration and treatment equipment will be located on the east side of the water well housing structure. Construction is expected to take 18 months. Once the construction is complete, the water wells will operate 24-hours a day. The operation of water wells chiefly is unmanned but will require a maintenance crew visit twice a week. A copy of the proposed site plan is in Appendix A. Standard Regulatory Requirements The Applicant is required to follow all existing standard regulations during construction. These include but are not limited to the following: Migratory Bird Treaty Act (MBTA) of 1918 (16 U.S.C. 703-712) Compliance. The MBTA of 1918 (16 U.S.C. 703-712), which was last updated in 2004 protects individuals as well as any part, nest, or eggs of any bird listed as 4-31 migratory. In practice, federal permits issued for activities that potentially impact migratory birds typically have conditions have require pre - disturbance surveys for nesting birds. In the event nesting is observed, a buffer area with a specified radius must be established, within which no disturbance or intrusion is allowed until the young have fledged and left the nest, or it has been determined that the nest has failed. If not otherwise specified in the permit, the size of the buffer area varies with species and local circumstances (e.g., busy roads, intervening topography, etc.) and is based on the professional judgement of a monitoring biologist. A list of migratory bird species protected under the MBTA is published by USFWS. State of California Fish and Game Code Section 3500, et. seq., Section 3503.5 of the California Fish and Game Code states that it is "unlawful to take, possess, or destroy any birds in the order Falconiformes or Strigiformes (birds of prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by this code or any regulation adopted pursuant thereto." Activities that result in the abandonment of an active bird of prey nest may also be considered in violation of this code. In addition, California Fish and Game Code, Section 3511 prohibits the taking of any bird listed as fully protected, and California Fish and Game Code, Section 3515 states that is it unlawful to take any non -game migratory bird protected under the MBTA. California Code of Regulations, Title 14, Section 4308 (14 CCR § 4308) (Accommodation for Unanticipated Cultural/Paleontological Resources). No person shall remove, injure, disfigure, deface, or destroy any object of archaeological or historical interest or value. California Health and Safety Code, and Public Resources Code (Human Remains). In the event that human remains are discovered, there shall be no disposition of such human remains, other than in accordance with the procedures and requirements set forth in California Health and Safety Code Section 7050.5 and Public Resources Code Section 5097.98. These code provisions require notification of the County Coroner and the Native American Heritage Commission, who in turn must notify those persons believed to be most likely descended from the deceased Native American for appropriate disposition of the remains. Excavation or disturbance may continue in other areas of the Project Site that are not reasonably suspected to overlie adjacent remains or archaeological resources. National Pollution Discharge Elimination System (NPDES). Because the site is greater than one acre, the applicant is required by the Santa Ana Regional Water Quality Control Board to prepare a Stormwater Pollution Prevention Plan (SWPPP) to address water quality and runoff during construction to comply with the State of California General Construction Permit. The SWPPP will outline the source control and/or treatment control Best Management 4-32 Practices (BMPs) to avoid or mitigate runoff pollutants at the construction site to the "maximum extent practicable." All recommendations in the Plan shall be implemented during area grading and construction. The Project shall comply with each of the recommendations detailed in the Plan, and other such measure(s) as the City deems necessary to mitigate potential stormwater runoff impacts. INFORMATION DEMONSTRATING THAT THE PROJECT SATISFIES THE CONDITIONS DESCRIBED IN SECTION 15332 OF TITLE 14 OF THE CALIFORNIA CODE OF REGULATIONS: Section 15332 of CEQA Guidelines states that "Class 32 consists of projects characterized as in -fill development meeting the conditions" described below: a. The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations. b. The proposed development occurs within city limits on a Project Site of no more than five acres substantially surrounded by urban uses. c. The Project Site has no value as habitat for endangered, rare, or threatened species. d. Approval of the project would not result in significant effects relating to traffic, noise, air quality, or water quality. e. The site can be adequately served by all required utilities and public services. The following analysis discusses the Proposed Project in relation to each condition as listed in CEQA Guidelines Section 15332: 1. Is the project consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations? The project site has a General Plan Land Use designation of Low Density Residential and is zoned R1. Pursuant to Government Code 53091, zoning and building codes do not apply to facilities for the generation of water, therefore the Project would be a permitted use in all zones. Nevertheless, the Project is consistent with the following General Plan Policies: Policy LU-1.1 Land use compatibility and viability. The Project is in the immediate vicinity of other public facilities. Specifically, Fountain Valley High School is within 250 feet from the Property. Additionally, the proposed well housing would have a residential design and be smaller size than other residences in the area. Landscape setbacks would be provided adjacent to La Amapola Avenue to further blend the 4-33 site into the residential neighborhood. Along Bushard, a block wall will be provided to match the height of other blocks walls in the area. Access to the site would be Bushard, a secondary arterial, further limiting impacts to the adjoining neighborhoods. Policy LU-3.2 Scale and character. The single -story well housing would have a residential design and be in scale with other single -story homes in the area. In fact, the Project is more consistent in scale and character with the residences under La Amapola when compared to the residential densities available through Senate Bill 9 and the various state law amendments authorizing accessory dwelling units. The City of Fountain Valley's municipal code requires a minimum lot size of 7,200 square feet, minimum lot width of 60 feet (45 feet for cul-de-sac lots), and lot depth of 90 feet. Based on its size and shape, the 22,172 square foot parcel could be subdivided into three parcels. Utilizing either ADU law and SB 9, or combination thereof, each of the subsequent parcels could build up to four dwelling units. This would result in twelve units being built on the site. In comparison to other uses, the Project will maintain a residential design and is in scale and character with the area. Policy PFS-1.1 Water supply and distribution. According to the Orange County Water District Engineer's Report2, water Conservation, recharge basins, and recent wet periods (2005-06, 201 1-12, 2018-19, and 2022-23) has resulted in an increase in groundwater supplies. The proposed water wells will not create a significant drawdown of the water basin and will not impact supply for the City of Fountain Valley. 2. Is the proposed development located within the city limits on a Project Site of no more than five acres substantially surrounded by urban uses? The Project Site is located within the City of Fountain Valley city limits. The Project limits include work on the Project Site and within the Bushard and Talbert rights -of - way. As noted in the following table, the total area within the project boundaries is 4.704 acres. Component Size Project Site 0.733 acre Bushard Street Right -of -Way 0.883 acre Talbert Avenue Right -of -Way 3.088 acres Total 4.704 acres All surrounding uses are urban uses, which include commercial and residential land uses. 2 https://www.ocwd.com/wp-content/uploads/2022-23-Engineers-Report-Final.pdf 4-34 3. Does the Project Site have value as habitat for endangered, rare, or threatened species? The Project Site is currently vacant but was previously improved with a single-family residence and commercial landscape nursery. Only ground cover (primarily weeds and grasses) remains on the site. It is located within a developed urban setting as surrounding uses are developed with commercial and residential uses. According to the U.S. Fish & Wildlife Service IPaC viewer3, there are no critical habitats on the Project Site. Furthermore, the Environmental Impact Report prepared for the 2023 City of Fountain Valley General Plan update4, states the only portion of the City that contain habitat is the region around Mile Square Park. The Project Site is over one mile from Mile Square Park and development of the water wells would not impact any habitat within the park. The Proposed Project would adhere to all applicable regulatory requirements. Landscape would be removed in accordance with the Migratory Bird Act and the California Fish and Game Code. Therefore, the Project Site has no value as habitat for endangered, rare, or threatened species. 4. Would approval of the project result in any significant effects relating to traffic, noise, air quality, or water quality? Traffic: a. Would the project conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? The City uses the Foutain Valley General Plan Mobility Elements to discuss the City's circulation system, including transit, roadway, bicycle, and pedestrian facilities. The Circulation Element establishes goals and policies that guide the City's mobility system, including streets, transit facilities, and pedestrian facilities. Access to the Project Site will be limited to Bushard Street, which is classified by the General Plan as a Secondary Arterial. Secondary Arterials are intended to distribute traffic between local streets and arterials, and can typically accommodate 25,000 average daily vehicle trips. Bushard is also listed on the Circulation Element Trails Plan Map as a Class II bike path. A Class II bike lane is provided on both sides of the street. The Proposed Project will not impact the roadway operations or bicycle access. The entry access gate will be setback from the sidewalk to allow maintenance 3 https://ipac.ecosphere.fws.gov/location/index 4 httl2s://www.fountainvalley.gov/DocumentCenter/View/l9301 /GPU-EIR s httl2s://www.fountainvalleygov/DocumentCenter/View/19654/Fountain Valley 2045 General Pla n 4-35 vehicles to stop to allow the gate to open without blocking the travel lanes. Additionally, the site will be chiefly unmanned and will not generate any significant number of vehicle trips to the roadway network. b. Would the project conflict or be inconsistent with CEQA Guidelines § 15064.3, subdivision (b)? CEQA Guidelines Section 15064.3 discusses that transportation impacts of projects are, in general, best measured by evaluating the Proposed Project's VMT. To analyze traffic impacts, the City has adopted The City of Fountain Valley Traffic Impact Analysis Guidelines for Land Use Projects in CEQA and for General Plan Consistency (Guidelines)6. All traffic impact analyses for CEQA are required to follow the City's TIA Guidelines. There are three types of VMT project screening that lead agencies can apply to effectively screen projects from project -level assessment. These are: Type 1: Transit Priority Area (TPA) Screening; Low VMT Area Screening; and lastly, Project Type Screening. Importantly, the Project only needs to fulfill one of these screening types to qualify for screening. Of the aforementioned types of screening, the Project screens out based on Project Type Screening. Specifically, the Guidelines state, "Local serving retail projects less than 50,000 square feet may be presumed to have a less than significant impact absent substantial evidence to the contrary." Furthermore, the Guidelines provide a list of projects that can be presumed to have a less than significant impact. Among the list includes projects that generate less than 1 10 net new daily vehicle trips. The Project is unmanned and will only generate a few vehicle trips per week for maintenance crews, far less than the 1 10 trips per day. Therefore, the Proposed Project would not conflict or be inconsistent with CEQA Guidelines Section 15064.3(b). c. Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? The Proposed Project does not involve any design features that would increase traffic hazards due to geometric design or incompatible uses. Access to the Project Site is proposed via driveways along Bushard Street with no access proposed on La Amapola Circle. The drive approaches will comply the City of Fountain Valley's Public Works standards. 6 https://www.fountainvalley.aov/DocumentCenter/View/l3730/VMT-Guidenliens City -of - Fountain -Valley 4-36 d. Would the project result in inadequate emergency access? The Proposed Project is required to located two water wells within a 2,400 square foot structure. Two access points are provided on Bushard Street to allow emergency ingress and egress. The building is within 150 feet of the right-of-way to allow the Fire Department to pull hoses onto the site without the need for on -site fire hydrants. As a result, the Proposed Project would not result in inadequate emergency access. Noise: A Noise Impact Analysis dated August 8, 2025 by Ganddini Group (Appendix B) was prepared for the Proposed Project to analyze the Proposed Project's potential noise impacts. As discussed below, approval of the Proposed Project would not result in any significant effects relating to noise. a. Would the project result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Construction Noise - The construction activities for the Proposed Project are anticipated to include preparation and grading of the site, drilling of the water wells, construction of the water well housing structure, site improvements, and installation of the water main and stormwater main in the right-of-way. The nearest sensitive receptor to the Project Site is the single-family residences located on the adjoining properties. Section 6.28.070 of the City's Municipal Code exempts construction noise that occurs between 7:00 a.m. and 8:00 p.m. from the stationary noise standard of 55 dB at the nearby residential property lines. Nighttime well drilling will be subject to the noise standards presented below in Sections 6.28.050 and 6.28.060. Specifically, drill noise will be considered significant if it exceeds an exterior noise level of 55 dBA Leq at the adjacent residential properties of if it is expected to exceed 45 dBA Leq inside any nearby residences. Construction noise levels will range between range between 44 and 57 dBA Leq at first floor levels of nearby residential properties and between 50 and 57 dBA Leq at second story levels of nearby residential properties (see Figure 6 - Construction Noise). As an added measure, a temporary noise barrier will be included to further reduce nighttime noise levels (see Figure 7 - Noise Barrier) 4-37 ►C�]Lw ��'..JJJ L.

Operational Noise IFW. dllid 'i..Ira , J I Roadway Vehicular Noise Vehicular noise is a combination of noise produced by engine, exhaust, and tires. The level of traffic noise depends on three primary factors (1) the volume of traffic, (2) the speed of traffic, and (3) the number of trucks in the flow of traffic. The Proposed Project does not propose a substantial increase in the number of vehicle trips to or from the site. No impact from roadway vehicular noise is anticipated. b. Would the project result in generation of excessive groundborne vibration or groundborne noise levels? Vibration is oscillatory motion through a solid medium, like the ground. Vibration amplitudes are usually expressed as either peak particle velocity (PPV) or the root mean square (RMS) velocity. The PPV is defined as the maximum instantaneous peak of the vibration signal in inches per second. The RMS of a signal is the average of the squared amplitude of the signal in vibration decibels (VdB), ref one micro - inch per second. Vibration can impact adjoining uses if it exceeds 85 VdB. Vibration impacts from construction activities associated with the Proposed Project would typically be created from the operation of heavy off -road equipment and drilling of water wells. Proposed well sites are no closer than 58 feet from the project site property line and groundborne vibration associated with well drilling is expected to be approximately 0.025 at that distance. Therefore, well drilling would not result in significant impacts related to groundborne vibration. Operations -related vibration impacts - Operation of the water wells is not anticipated to generate vibration. The only potential for impact is from vehicles and trucks driving on the site. Loaded trucks generally have a VdB of 85.6 at a distance of 25 feet the VdB decreases over distance, therefore based on the distance to the nearest residential structure, vibration levels will not exceed the 85 VdB threshold and no impact is expected. c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? The nearest airport is John Wayne Airport, located in Santa Ana, California, which is approximately 5.5 miles from the Project Site. The Project Site is not located within the airport's land use plan area. Furthermore, the Proposed Project is not expected to expose people residing or working in the Proposed Project area to excessive noise levels. Therefore, the Proposed Project would have no impact on exposing people residing or working in the area to excessive airplane noise. 4-41 Air Quality: a. Would the project conflict with or obstruct implementation of the applicable air quality plan? The Project Site is located within the South Coast Air Basin (SCAB) which is characterized by relatively poor air quality and is a Federal- and State- designated nonattainment area for 03, PM10 and PM2.5 (US EPA 2012). The South Coast Air Quality Management District (SCAQMD) has established significance thresholds for both construction and operational activities relative to these criteria pollutants. The Project Site is located within the Coastal general forecasting area and Central Orange County air monitoring area (SRA-17). The nearest air monitoring station to the Project Site is located in Anaheim near Interstate 5 and Ball Road (ARB #30031). Air monitoring areas and stations provide air pollutant data to comprise a "background" for the project location and the existing local air quality. As discussed below under threshold b and threshold c, implementation of the Proposed Project would result in less than significant impacts relative to the daily significance thresholds for criteria air pollutant construction emissions established by SCAQMD. By complying with the thresholds of significance, the Proposed Project would be incompliance with the SCAQMD Air Quality Management Plan (AQMP) and the federal and state air quality standards. b. Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non -attainment under an applicable federal or state ambient air quality standard? Construction The construction activities can generate criteria pollutants through the operation of construction equipment and from fugitive dust. Current requirements of the California Air Resources Board (CARB) require construction fleets to utilize low emission vehicles and ensure all vehicles in use are properly maintained to minimize impacts.? California Code of Regulations Title 13, Article 4.8, Chapter 9, Section 2449 regulates emissions from off -road diesel equipment in California. This regulation limits idling of equipment to no more than five minutes, requires equipment operators to label each piece of equipment and provide annual reports to CARB of their fleet's usage and emissions. In addition to the fleet requirements, fugitive dust control measures that exceed South Coast Air Quality Management District's Rule 403 will be utilized. This includes: • Requiring use of nontoxic soil stabilizers to reduce wind erosion. • Applying water every four hours to active soil disturbing activities. • Tarping and/or maintaining a minimum of 24 inches of freeboard on trucks 7 https://ww2.arb.ca.gov/sites/default/files/barcu/regact/2022/off-roaddiesel/froa-1.pdf 4-42 hauling dirt, sand, soil, or other loose materials. As a result of the implementation of existing regulations, the Proposed Project's short-term construction impact on regional or localized air resources would be less than significant. Operational Emissions Operation of the Proposed Project is not anticipated to create any air quality emissions or criteria pollutants. The water well pumps are powered electrically and connected to the existing power grid. Furthermore, the site is unmanned only generating a few vehicle trips a week for maintenance. These minimal number of vehicle trips would not contribute substantially to an existing or projected air quality violation. By complying with the SCAQMD standards, the Proposed Project would not contribute to a cumulatively considerable net increase of any criteria pollutant for which the project region is in non -attainment under an applicable Federal or State ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors). Therefore, the Proposed Project's long-term regional and local air quality impacts will be less than significant. c. Would the project expose sensitive receptors to substantial pollutant concentrations? Sensitive receptors are the single-family residences that are adjacent to the Project Site. The greatest potential for toxic air contaminant (TACs) emissions would be related to diesel particulate matter (DPM) emissions associated with heavy equipment operations during construction of the Proposed Project. According to SCAQMD methodology, health effects from carcinogenic air toxics are usually described in terms of "individual cancer risk". "Individual cancer risk" is the likelihood that a person exposed to concentrations of toxic air contaminants over a 70-year lifetime will contract cancer, based on the use of standard risk - assessment methodology. Given the relatively limited number of heavy-duty construction equipment, the varying distances that the construction equipment would operate to the nearby sensitive receptors, and the short-term construction schedule, the Proposed Project would not result in a long-term (i.e., 30 or 70 years) substantial source of toxic air contaminant emissions and corresponding "individual cancer risk". In addition, California Code of Regulations Title 13, Article 4.8, Chapter 9, Section 2449 regulates emissions from off -road diesel equipment in California. This regulation limits idling of equipment to no more than five minutes, requires equipment operators to label each piece of equipment and provide annual reports to CARB of their fleet's usage and emissions. This regulation also requires systematic upgrading of the emission Tier level of each fleet, and currently no commercial operator is allowed to purchase Tier 0, Tier 1 or Tier 2 equipment. In 4-43 addition to the purchase restrictions, equipment operators need to meet fleet average emissions targets that become more stringent each year between years 2014 and 2023. By January, 2026, 75 percent or more of all contractors' equipment fleets must be Tier 2 or higher and by January, 2029, 100 percent of all equipment fleets must be Tier 2 or higher. Therefore, no significant short-term DPM impacts would occur during construction of the Proposed Project. d. Would the project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? Land uses that commonly receive odor complaints include agricultural uses (farming and livestock), chemical plants, composting operations, dairies, fiberglass molding facilities, food processing plants, landfills, refineries, rail yards, and wastewater treatment plants. The Proposed Project is not anticipated to generate odors. Water Quality: a. Would the project violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? Construction Impacts Construction -related runoff pollutants are typically generated from waste and hazardous materials handling or storage areas, outdoor work areas, material storage areas, and general maintenance areas (e.g., vehicle or equipment fueling and maintenance, including washing). Construction projects that disturb one acre or more of soil, including the Proposed Project, are regulated under the Construction General Permit (CGP, Order No. 2022-0057-DWQ) issued by the State Water Resources Control Board (SWRCB). Projects obtain coverage under the CGP by developing and implementing a stormwater prevention pollution plan (SWPPP), estimating sediment risk from construction activities to receiving waters, and specifying best management practices that would be implemented as a part of the Proposed Project's construction phase to minimize pollution of stormwater prior to and during grading and construction. The contractor would be required to prepare and implement a SWPPP and associated BMPs in compliance with the CGP during grading and construction. The SWPPP would specify BMPs that would be implemented for the Proposed Project to protect the water quality of receiving waters. Other construction BMPs that may be incorporated into the Proposed Project's SWPPP and implemented during the construction phase include but are not limited to: • Installation of perimeter silt fences and perimeter sandbags and/or gravel bags / / / • Stabilized construction exits with rumble strips)/plate(s) • Installation of storm drain inlet protection on affected roadways • Installation of silt fences around stockpile and covering of stockpiles • Stabilization of disturbed areas where construction ceases for a determined period of time (e.g., one week) with erosion controls • Installation of temporary sanitary facilities and dumpsters Adherence to the BMPs in the SWPPP would reduce, prevent, minimize, and/or treat pollutants and prevent degradation of downstream receiving waters; reduce or avoid contamination of urban runoff with sediment; and reduce or avoid contamination with other pollutants such as trash and debris, oil, grease, fuels, and other toxic chemicals. b. Would the project substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? The Proposed Project is intended to pump groundwater from the aquifer. These two water wells would allow Newport Beach to extract 5,000-6,000-acre feet of water per year, which would not impact the aquifer. According to the Orange County Water District (OCWD), the Orange County Groundwater Basin holds over 40 million acre-feet with a current operational capacity of 500,000 acre-feet.$ Total water demands within OCWD for the 2022-2023 water year was 351,719 acre-feet, which was the lowest in 50 years,9 despite an increase in development within the County. Increasing the demand by extracting an additional 6,000 acre-feet would not impact the aquifer and not result in a substantial decrease in the groundwater supply. c. Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would result in a substantial erosion or siltation on- or off -site; substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off -site; create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff, or impede or redirect flood flows? The existing Project Site is currently vacant. In the existing condition, drainage of the site generally surface flows towards Bushard Street, thence south to a curb inlet catch basins near Talbert Avenue. The Proposed Project would install multiple drainage catch basins on site, which will connect to a new storm drain that will connect to the existing off -site storm drain system. This will result in improved 8 https://www.ocwd.com/wp-content/uploads/GWRS-TechnicalBrochure WEB.pdf 9 https://www.ocwd.com/wp-content/uploads/2022-23-Engineers-Report-Final.pdf 4-45 drainage patterns and prevent uncontrolled surface drainage from the site. d. In flood hazard, tsunami, or seiche zones, would the project risk release of pollutants due to project inundation? The Project Site is located within the United States Geological Survey (USGS) 2022 Newport Beach, California 7.5-minute, 24000 topographic quadrangle. The Project Site is also located within FEMA Flood Plain Panel 06059CO254J and is designated within Zone X, which is described as an "area with reduced flood risk due to levee" The Project Site is located outside of the 100-year flood plain, and would not impede or redirect flood flows. Furthermore, onsite storm drain catch basins would be designed to prevent pollutants from entering to the storm drain system. Seiches are surface waves created when a body of water is shaken, usually by earthquake activity. Seiches are of concern relative to development near large water bodies and water storage facilities, because inundation from a seiche can occur if the wave overflows a containment wall, such as the wall of a reservoir, water storage tank, dam, or other artificial body of water. Due to the distance from any body of water, seiches are not anticipated to impact the project site. e. Would the project conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? The Proposed Project involves the construction of two water wells and its associated infrastructure. The Project will incorporate storm water and urban runoff pollution prevention controls, and best management practices (BMPs) on construction sites in accordance with the Orange County MS4 Permit. Therefore, the Project would not conflict or obstruct implementation of a water quality control plan. At full operation, the two water wells are expected to extract 5,000-6,000-acre feet of water per year from the aquifer. According to the Orange County Water District (OCWD), the Orange County Groundwater Basin holds over 40 million acre-feet with a current operational capacity of 500,000 acre-feet per year. Current extraction rates are approximately 350,0009 acre-feet per year. The additional extraction from these two wells will not impact sustainable management of the ground water supply or exceed operational capacity of groundwater extraction. 5. Can the Project Site be adequately served by all required utilities and public services? a. Fire Protection: According to CAL FIRE's Fire Hazard Severity Zone (FHSZ) Map, the Project Site is not designated in a Very High, High, or Moderate FHSZ for either the Local Responsibility Area (LRA) or State Responsibility Area (SRA). The Proposed Project 9 ,, does not introduce any features that would require additional fire services beyond what is already serviced to the City. Fire services are provided to the City by the Fountain Valley Fire Department. The nearest Fire Station is Fountain Valley Fire Station 1, which is located at 17737 Bushard Steet. This Fire Station is less than 1,000 feet from the Project Site. b. Police Protection: Police Protection for the Project Site would be provided by the Fountain Valley Police Department. The Proposed Project will be unmanned and is not anticipated to generate growth or new employment. Calls for Police Services are not anticipated to increase beyond those required for the existing vacant site. Therefore, no impact is expected. Installation of new water wells would provide the City of Newport Beach with additional water supply, which could spur growth in Newport. Notwithstanding this, new development in Newport Beach is limited to what was previously analyzed under the City's General Plan buildout scenario.10 This buildout scenario already considers needed growth in Police Services. Therefore, the project will not impact police protection. c. Schools: Since the Proposed Project will be unmanned and is not anticipated to generate growth or new employment, impacts to Fountain Valley schools will not occur. Nevertheless, the additional water supply for the City of Newport Beach could induce growth. Impacts on schools resulting from this additional growth was previously analyzed in the City of Newport Beach General Plan buildout scenario. Further, school enrollment for the Newport -Mesa Unified School District'' has been trending down year to year, providing sufficient capacity for any minimal indirect increase in school enrollments resulting from the project. d. Parks: Since the Proposed Project will be unmanned and is not anticipated to generate growth or new employment, impacts to Fountain Valley parks will not occur. Nevertheless, the additional water supply for the City of Newport Beach could induce growth. Impacts on parks resulting from this additional growth was previously analyzed in the City of Newport Beach General Plan buildout scenario. 10 htti2s://www.newportbeachca.gov/government/departments/community- development/planning-division/general-plan-codes-and-regulations/general-plan htti2s://www.ed-data.org/district/Orange/Newport--Mesa-Unified/ps Mzg2NzA%5E 4-47 e. Other Public Facilities: Other public facilities, such as library services will not be impacted since the Proposed Project will be unmanned and is not anticipated to generate growth or new employment in Fountain Valley. Any impacts resulting in growth in the City of Newport Beach were previously analyzed in the City of Newport Beach General Plan buildout scenario. f. Wastewater/Sewer: The water wells will not generate wastewater. No impacts will occur. g. Storm Water Drainage: The proposal includes constructing an 18-inch reinforced concrete storm drain that will connect from a drain box adjacent to each of the water wells, through Bushard Street right-of-way, to the existing storm drain in Talbert Avenue. The Talbert Avenue storm drain flows into the Talbert Channel, which ultimately drains into the Pacific Ocean near Brookhurst Street and Pacific Coast Highway. The new storm drain is proposed to accommodate flushing of the wells and onsite drainage. Tin 2022 the City of Fountain Valley prepared an Infrastructure Technical Report12 as part of the General Plan Update. This technical report did not find any deficiencies in the existing storm drain system. h. Water Supplies: The proposed project will increase water supplies for the City of Newport Beach. As noted in Section 4.e. of this analysis, operations of the water wells will not impact ground water supplies for other communities. i. Solid Waste Disposal: The water wells will not generate solid waste. No impacts will occur. j. Electricity: k. Natural Gas: I. Telephone Service: m. Television Service: The Project Site is in a built -out, urban setting. The Project Site and the surrounding properties are fully served by various utility service providers, including: • Electric: Southern California Edison (SCE) • Natural Gas: Southern California Gas (SoCalGas) • Telecommunications: AT&T, Frontier, Verizon, T-Mobile, Spectrum 12 https://www.fountainvalley.aov/DocumentCenter/View/l7436/Appendix 513-1 -Existing= Conditions-Infrastructure-Report?bid Id= EXCEPTIONS: CEQA Guidelines Section 15300.2 outlines exceptions, such as if a project results in a cumulatively significant impact, that would render a project inapplicable for a Categorical Exemption. As discussed in the analysis above, the Proposed Project would not result in any significant impact or cumulatively significant impact on the environment. Additionally, the Proposed Project would not result in damage to scenic resources or a substantial adverse change in the significance of a historical resource. The Project Site is located on a site that is developed with a commercial office building and surface parking. The Proposed Project would consist of infill development on a site that is not listed on any list compiled pursuant to Section 65962.5 of the Government Code. The following analysis discusses the Proposed Project in relation to CEQA Guidelines Section 15300.2 - Exceptions. a. Location. Classes 3, 4, 5, 6, and I I are qualified by consideration of where the project is to be located - a project that is ordinarily insignificant in its impact on the environment may in a particularly sensitive environment be significant. Therefore, these classes are considered to apply all instances, except where the project may impact on an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies. The Proposed Project does not qualify for the Class 3, 4, 5, 6, or 11 categorical exemptions. Therefore, exception A of Section 15300.2 is not applicable to the Proposed Project. b. Cumulative Impact. All exemptions for these classes are inapplicable when the cumulative impact of successive projects of the same type in the same place, over time is significant. As discussed above under threshold questions three through five, the Proposed Project would not have a cumulative impact of successive projects of the same type in the same place, over time. The Proposed Project would consist of a new auto dealership development and does not propose to redevelop the site with successive projects of the same type over time. c. Significant Effect. A categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances. As discussed above under threshold questions three through five, the Proposed Project would not have any significant effect related to traffic, noise, air quality, water quality, and biological and cultural resources. The Proposed Project falls below regulatory thresholds and would adhere to all applicable regulations, such 9 ,. as the City's Municipal Code. d. Scenic Highways. A categorical exemption shall not be used for a project which may result in damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway. This does not apply to improvements which are required as mitigation by an adopted negative declaration or certified EIR. The California Department of Transportation (Caltrans) manages the State Scenic Highway Program and provides a State Scenic Highway Map tool on the Caltrans website. According to the Caltrans State Scenic Highway Map tool13, there are no scenic highways on or adjacent to the Project Site. The closest scenic highway is Pacific Coast Highway, which at its nearest point is located approximately 4 miles southwest of the Project Site. e. Hazardous Waste Sites. A categorical exemption shall not be used for a project located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code. According to the California Environmental Protection Agency (CaIEPA) and the Department of Toxic Control Substances (DTSC)'s Cortese List (Section 65962.5 of the Government Code) The Project Site is not located on the Cortese List or on any database of hazardous substance release sites, such as the EnviroStor database. Therefore, exception E is not applicable to the Proposed Project. f. Historical Resources. A categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource. According to the California Register of Historic Resources14 and the National Register of Historic Placesls, the Project Site is not designated as a historic place or resource. The City of Fountain Valley does not have a historic resource ordinance or list. Therefore, exception F is not applicable to the Proposed Project. CONCLUSION: Based on the analysis above, the Proposed Project is classified as a Class 32 pursuant to CEQA Guidelines Section 15300 and is categorically exempt from CEQA. 13 https://www.arcgis.com/al2ps/webappviewer/index.html?id=465dfd3d807c46cc8e80571 16f1 aaca a 14 httl2s://ohp.parks.ca.gov/ListedResources/?view=county&criteria=30 15 htti2s://www.nps.gov/maps/full.html?mapld=7ad17cc9-b808-4ff8-a2f9-a99909164466 4-50 DETERMINATION: I find that the analysis adequately supports each question and that the effects of the Proposed Project are typical of those generated within that class of projects (i.e., Class 32 - Infill Development Projects) characterized as in -fill development meeting the conditions of Section 15332 of Title 14 of the California Code of Regulations. The Proposed Project would not cause a significant effect on the environment and is, therefore, categorically exempt from the requirement for the preparation of environmental documents under the California Environmental Quality Act.

The drilling will occur 24 hours per day for several weeks. Once complete, the two well heads will be contained in a 2,400 square foot structure. Maintenance workers will visit the site every few days, but no other activity is expected. Existing Noise Environment The proposed project is located in a built -out suburban area with single-family land uses to the north, south and east and Bushard Avenue and multiple family land uses to the west. Existing noise levels in the project vicinity range between 40.0 and 69.5 dBA Leq. The dominant noise source in the project vicinity was vehicle traffic. Secondary noise sources included residential ambiance, pedestrians, bird song, and occasional aircraft overflight. Construction Noise Construction noise levels will range between range between 44 and 57 dBA Leq at first floor levels of nearby residential properties and between 50 and 57 dBA Leq at second story levels of nearby residential properties without the use of noise barriers during construction; therefore, noise levels at several of the affected receptors would exceed the City's nighttime standard of 50 dBA without the use of noise barriers during construction. The following noise reduction measure is recommended during construction to ensure the project does not exceed applicable nighttime noise standards: Recommendation #1 Prior to commencement of well drilling, the project shall install temporary noise barriers with an STC rating of at least 20 dB around each well drill as illustrated on Figure 10 and Figure 12. The temporary noise barriers should measure 8 feet high along the south, east, and west sides and 12 feet high along the north side of the well drills, and shall remain in place through completion of all well drilling activity. No mitigation measures would be required with implementation of Recommendation #1 into the project construction plans. Operational Noise Operational noise levels will range between range between 36 and 49 dBA Leq at first floor levels of nearby residential properties and between 46 and 56 dBA Leq at second story levels of nearby residential properties. The modeling that was conducted to arrive at these sound levels assumes installation of the eight -foot concrete wall shown as shown in on the proposed site plan; and installation of metal acoustical paneling on interior walls of the proposed building similar to what is provided inside of the building at 17399 Magnolia Street. Operational noise impacts would be less than significant and no mitigation is required. Groundborne Vibration Impacts The proposed well sites are no closer than 58 feet from the project site property line and groundborne vibration associated with well drilling is expected to be approximately 0.025 at that distance. Therefore, well drilling would not result in significant impacts related to groundborne vibration. No mitigation is required. 93-dil Bushard Street Water Well Project Noise Impact Analysis iii 19786 4-59 The most substantial sources of groundborne vibration during post -construction project operations will include the movement of passenger vehicles and trucks on paved and generally smooth surfaces. Loaded trucks generally have a VdB of 85.6 at a distance of 25 feet (Caltrans 2020), As stated previously, the nearest structure is 50 feet from the proposed alignment. Therefore, groundborne vibration levels generated by project operation would not exceed the City groundborne vibration standard for land uses of 85 VdB at a sensitive receptor. Groundborne vibration impacts would be less than significant and no mitigation is required. Air Traffic As the proposed well site is located approximately 5.6 miles northwest of the nearest airport (John Wayne Airport) and is not located within an airport noise contour. The project would not expose people residing or working in the project area to excessive noise levels associated with airports; impacts are less than significant and no mitigation is required. iv Bushard Street Water Well Project Noise Impact Analysis 19786 4-60 1. INTRODUCTION This section describes the purpose of this study and the proposed project. PURPOSE AND OBJECTIVES The purpose of this report is to provide an assessment of potential noise impacts associated with construction and operation of the proposed project and incorporate any needed noise reduction measures into the project design. The noise issues related to the proposed land use and development have been evaluated considering applicable Federal, State, and local policies, including those of the City of Fountain Valley. Although this is a technical report, effort has been made to write the report clearly and concisely. A list of acronyms and a glossary are provided in Appendix A and Appendix B of this report to assist the reader with technical terms related to noise analysis. PROJECT LOCATION The project site is located at 17902 Bushard in the City of Fountain Valley, California. Existing single family residential land uses border the project site on the north, south and east; and Bushard Street borders project site on the west. A vicinity map showing the project location is provided on Figure 1. PROJECT DESCRIPTION The proposed project involves the drilling of two water wells: one to a depth of 300 feet and the other to a depth of 700 feet. The drilling will occur 24 hours per day for several weeks. Once complete, the two well heads will be contained in a 2,400 square foot structure. Maintenance workers will visit the site every few days, but no other activity is expected. The proposed site plan is provided in Figure 2. g3rdipl Bushard Street Water Well Project Noise Impact Analysis 19786 4-61 g3ldil }�, � �, Figure 1 Project Location Map Bushard Water Wells Noise Impact Analysis 19786 4-62 93')dJii Figure 2 Site Plan Bushard Water Wells Noise Impact Analysis 19786 4-63 2. NOISE AND VIBRATION FUNDAMENTALS This section provides an overview of key noise and vibration concepts NOISE FUNDAMENTALS Sound is a pressure wave created by a moving or vibrating source that travels through an elastic medium such as air. Noise is defined as unwanted or objectionable sound. The effects of noise on people can include general annoyance, interference with speech communication, sleep disturbance, and in extreme circumstances, hearing impairment. Commonly used noise terms are presented in Appendix B. The unit of measurement used to describe a noise level is the decibel (dB). The human ear is not equally sensitive to all frequencies within the sound spectrum. Therefore, the "A -weighted" noise scale, which weights the frequencies to which humans are sensitive, is used for measurements. Noise levels using A -weighted measurements are written dB(A) or dBA. From the noise source to the receiver, noise changes both in level and frequency spectrum. The most obvious is the decrease in noise as the distance from the source increases. The manner in which noise reduces with distance depends on whether the source is a point or line source as well as ground absorption, atmospheric effects and refraction, and shielding by natural and manmade features. Sound from point sources, such as air conditioning condensers, radiates uniformly outward as it travels away from the source in a spherical pattern. The noise drop-off rate associated with this geometric spreading is 6 dBA per each doubling of the distance (dBA/DD). Transportation noise sources such as roadways are typically analyzed as line sources, since at any given moment the receiver may be impacted by noise from multiple vehicles at various locations along the roadway. Because of the geometry of a line source, the noise drop-off rate associated with the geometric spreading of a line source is 3 dBA/DD. Decibels are measured on a logarithmic scale, which quantifies sound intensity in a manner similar to the Richter scale used for earthquake magnitudes. Thus, a doubling of the energy of a noise source, such as a doubled traffic volume, would increase the noise levels by 3 dBA; halving of the energy would result in a 3 dBA decrease. Figure 3 shows the relationship of various noise levels to commonly experienced noise events. Average noise levels over a period of minutes or hours are usually expressed as dBA Leq, or the equivalent noise level for that period of time. For example, Uq(s) would represent a 3-hour average. When no period is specified, a one -hour average is assumed. Noise standards for land use compatibility are stated in terms of the Community Noise Equivalent Level (CNEL) and the Day -Night Average Noise Level (DNL). CNEL is a 24-hour weighted average measure of community noise. CNEL is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), and by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the evening and nighttime hours. DNL is a very similar 24- hour average measure that weights only the nighttime hours. It is widely accepted that the average healthy ear can barely perceive changes of 3 dBA; that a change of 5 dBA is readily perceptible, and that an increase (decrease) of 10 dBA sounds twice (half) as loud. This definition is recommended by the California Department of Transportation's Technical Noise Supplement to the Traffic Noise Analysis Protocol (2013). VIBRATION FUNDAMENTALS The way in which vibration is transmitted through the earth is called propagation. Propagation of earthborn vibrations is complicated and difficult to predict because of the endless variations in the soil through which waves travel. There are three main types of vibration propagation: surface, compression and shear waves. An, Bushard Street Water Well Project Noise Impact Analysis 19786 4-64 Surface waves, or Rayleigh waves, travel along the ground's surface. These waves carry most of their energy along an expanding circular wave front, similar to ripples produced by throwing a rock into a pool of water. Compression waves, or P-waves, are body waves that carry their energy along an expanding spherical wave front. The particle motion in these waves is longitudinal (i.e., in a "push-pull" fashion). P-waves are analogous to airborne sound waves. Shear waves, or S-waves, are also body waves that carry energy along an expanding spherical wave front. However, unlike P-waves, the particle motion is transverse or "side -to -side and perpendicular to the direction of propagation". As vibration waves propagate from a source, the energy is spread over an ever-increasing area such that the energy level striking a given point is reduced with the distance from the energy source. This geometric spreading loss is inversely proportional to the square of the distance. Wave energy is also reduced with distance as a result of material damping in the form of internal friction, soil layering, and void spaces. The amount of attenuation provided by material damping varies with soil type and condition as well as the frequency of the wave. Vibration amplitudes are usually expressed as either peak particle velocity (PPV) or the root mean square (RMS) velocity. The PPV is defined as the maximum instantaneous peak of the vibration signal in inches per second. The RMS of a signal is the average of the squared amplitude of the signal in vibration decibels (VdB), ref one micro -inch per second. The Federal Railroad Administration uses the abbreviation "VdB" for vibration decibels to reduce the potential for confusion with sound decibel. PPV is appropriate for evaluating the potential of building damage. Decibel notation acts to compress the range of numbers required in measuring vibration. Similar to the noise descriptors, Leq and Lmax can be used to describe the average vibration and the maximum vibration level observed during a single vibration measurement interval. Figure 4 illustrates common vibration sources and the human and structural responses to ground -borne vibration. 931JJ11 Bushard Street Water Well Project Noise Impact Analysis 19786 4-65 SOUND COMMON OUTDOOR LEVEL COMMON INDOOR SOUND LEVELS dBA SOUND LEVELS Jet Take Off (ot 100 ft)�` �r !'�• Firecrackers Ito Car Horn (at 3 ft) Rack Band (at SD ft} --tit 200 - Inside Subway Train (New fork) �� Gas Lawn Mower (at 3 ft) • ri7 Diesel Truck (at 150 ft) 90 _� - Food Blender (at 3 tit) Garbage Disposal (at 3 ft) ..rrlrni Shouting (at 3 ft) RpW� Noisy Urban Area • i9 -' 70 Vacuum Cleaner (at 10 ft) -� Busy Highway (at 50 ft) — �► • - s Normal Speech (at 3 ft) Commercial Area i Large Business Office Quiet Urban Area s Dishwasher (in Adjacent Room) ' Quiet Rural Area Small Theater Conference Room (Background) j Library s Bedroom (at Night) Concert Nall (Background) Recording Studio Threshold of Hearing © Ganddini Group, Inc.

EXISTING NOISE ENVIRONMENT This section describes the existing noise setting in the project vicinity. EXISTING LAND USES AND SENSITIVE RECEPTORS The project site is bound by existing single family residential land uses on the north, south and east. Bushard Avenue borders the street to the west. There are multiple family residential units located west of Bushard Avenue. All of the above -mentioned residential land uses are considered to be sensitive receptors that may be affected by project generated noise. AMBIENT NOISE MEASUREMENTS An American National Standards Institute (ANSI Section S1.4 2014, Class 1) Larson Davis model LxT sound level meter was used to document existing ambient noise levels. In order to document existing ambient noise levels in the project area, one (1) long term (24-hours) and four (4) 15-minute daytime noise measurements were taken using a Type I Larson Davis Noise Meter. Figure 5 shows the noise measurement location map. Field worksheets and noise measurement worksheets are provided in Appendix C. As shown on Figure 5, existing ambient noise measurements were taken at the following locations: ■ LTNM1: represents the existing noise environment of the project site as well as the nighttime noise levels associated with STNMs 1-3, all single-family residences. ■ STNM1: represents the existing noise environment of the residential uses in the vicinity of 9529 La Amapola Avenue adjacent to the project site to the north. ■ STNM2: represents the existing noise environment of the residential uses located in the vicinity of 9525 Acklay Circle adjacent to the project site to the south. ■ STNM3: represents the existing noise environment of the residential uses located in the vicinity of 9540 La Amapola Avenue, adjacent to the project site to the east. ■ STNM4: represents the existing noise environment of the residential uses located in the vicinity of 17697 Bushard Street west of the project site and west of Bushard Avenue. Table 1 provides a summary of the short-term ambient noise measurements which ranged between 55.1 and 69.5 dBA Lea; and Table 2 provides a summary of the long-term ambient noise measurements which ranged between 40.0 and 63.4 dBA Lea. The dominant noise source in the project vicinity was vehicle traffic. Secondary noise sources included residential ambiance, pedestrians, bird song, and occasional aircraft overflight. gndipi Bushard Street Water Well Project Noise Impact Analysis 19786 4-68 Table 1 Short -Term Noise Measurement Summary (dBA) Site Location Time Started Leq Lmax L(2) L(8) L(25) L(50) STNM1 2:18 PM 59.2 70.5 65.6 63.4 60.5 56.9 STNM2 2:41 PM 58.6 68.3 64.6 62.7 60.1 56.8 STNM3 3:06 PM 55.1 63.4 60.9 59.5 56.4 52.8 STNM4 3:39 PM 69.5 84.7 77.0 73.9 70.8 65.5 N otes: (1) See Figure 5 for noise measurement locations.

REGULATORY SETTING This section documents the regulatory framework and applicable noise standards. CITY OF FOUNTAIN VALLEY GENERAL PLAN Goal PFS-5 Protect public health and welfare by eliminating existing noise problems and preventing significant degradation of the acoustic environment. Policy PFS-5.1 Land use compatibility. Approve development and require mitigation measures to ensure existing and future land use compatibility as shown in the City's Noise Control Ordinance and state interior and exterior noise standards. Policy PFS-5.3 New nonresidential. When new nonresidential development is proposed adjacent to land designated for residential uses, require the developer to assess the potential noise impacts and fund feasible noise -related mitigation measures. CITY OF FOUNTAIN VALLEY MUNICIPAL ORDINANCE Construction Noise Section 6.28.070 Special Provisions Noise sources associated with the construction, repair, remodeling or grading of any real property, provided said activities take place between the hours of seven a.m. and eight p.m. Monday through Friday, nine a.m. through eight p.m. on Saturday and at no time on Sunday or any legal holiday are exempt from the noise standards presented in Sections 6.28.050 and 6.28.060. For purposes of this exception the use of saws, buffers, sanders, drills, and sprayers shall be included, as shall similar activity. Nighttime well drilling will be subject to the noise standards presented below in Sections 6.28.050 and 6.28.060. Specifically, drill noise will be considered significant if it exceeds an exterior noise level of 55 dBA Leq at the adjacent residential properties of if it is expected to exceed 45 dBA Leq inside any nearby residences. Operational Noise Section 6.28.050. Exterior noise standards. (a) The following noise standards, unless otherwise specifically indicated, shall apply to all residential property within a designated noise zone: Noise Zone Noise Level (dBA) Time Period 55 7:00 AM - 10:00 PM 50 10:00 PM - 7:00 AM In the event the alleged offensive noise consists entirely of impact noise, simple tone noise, speech, music, or any combination thereof, each of the above noise levels shall be reduced by 5 dB(A). (b) It is unlawful for any person at any location within the city to create any noise, or to allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, when the foregoing causes the noise level, when measured on any other residential property, either incorporated or unincorporated, to exceed: (1) The noise standard for a cumulative period of more than thirty minutes in any hour; or g3rdipl Bushard Street Water Well Project Noise Impact Analysis 19786 4-72 (2) The noise standard plus five dB(A) for a cumulative period of more than fifteen minutes in any hour; or (3) The noise standard plus ten dB(A) for a cumulative period of more than five minutes in any hour; or (4) The noise standard plus fifteen dB(A) for a cumulative period of more than one minute in any hour; or (5) The noise standard plus twenty dB(A) for any period of time. (c) In the event the ambient noise level exceeds any of the first four noise limit categories set forth in subsection (b) of this section, the cumulative period applicable to said category shall be increased to reflect said ambient noise level. In the event the ambient noise level exceeds the fifth noise limit category, the maximum allowable noise level under said category shall be increased to reflect the maximum ambient noise level. For noise sources that are generally constant or otherwise last for several hours, i.e. HVAC, fans, and pumps, it is industry practice to evaluate noise impacts in light of the 30-minute Leq as it is the most conservative. 6.28.060. Interior noise standards. (a) The following interior noise standards, unless otherwise specifically indicated, shall apply to all residential property within a designated noise zone: Noise Zone Noise Level (dBA) Time Period 55 7:00 AM - 10:00 PM 45 10:00 PM - 7:00 AM In the event the alleged offensive noise consists entirely of impact noise, simple tone noise, speech, music, or any combination thereof, each of the above noise levels shall be reduced by five dB(A). (b) It is unlawful for any person at any location within the city to create any noise, or to allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, when the foregoing causes the noise level when measured within any other dwelling unit on any residential property, either incorporated or unincorporated, to exceed: (1) The interior noise standard for a cumulative period of more than five minutes in any hour; or (2) The interior noise standard plus five dB(A) for a cumulative period of more than one minute in any hour; or (3) The interior noise standard plus ten dB(A) for any period of time. (c) In the event the ambient noise level exceeds either of the first two noise limit categories set forth in subsection (b) of this section, the cumulative period applicable to said category shall be increased to reflect said ambient noise level. In the event the ambient noise level exceeds the third noise limit category, the maximum allowable noise level under said category shall be increased to reflect the maximum ambient noise level. FEDERAL TRANSIT ADMINISTRATION The Federal Transit Administration (FTA) has published reasonable criteria for assessing construction and groundborne vibration impacts (FTA 2018) that is appropriate to supplement lead agency criteria or to use as the primary criteria when appropriate. FTA construction noise criteria is presented in The FTA construction noise criteria is based on the potential for adverse community reaction. As shown in Table 3, the daytime noise threshold for residential land uses is 80 dBA Leq averaged over an 8-hour period (Leq (8-hr); and the nighttime noise threshold is 70 dBA Leq (8-hr). 93T.Bn'' Bushard Street Water Well Project Noise Impact Analysis 19786 4-73 The FTA has adopted vibration standards that are used to evaluate potential building damage impacts related to construction activities. As shown in Table 4, the threshold at which there is a risk to "architectural" damage to non -engineered timber and masonry buildings is a peak particle velocity (PPV) of 0.2 inches/second at engineered concrete and masonry buildings a PPV of 0.3, and at reinforced -concrete, steel, or timber buildings a PPV of 0.5 inches/second.

ANALYTICAL METHODOLOGY AND MODEL PARAMETERS This section discusses the analysis methodologies used to assess noise impacts. WELL DRILLING NOISE MODELING The project will require the drilling of two water wells: one to a depth of 300 feet and the other to a depth of 700 feet. The drilling will occur 24 hours per day for several weeks. The wells will be drilled consecutively, not concurrently. The Sound PLAN model was used to model well drilling at nearby sensitive receptors. A noise reference level of 84 dB at a distance of 50 feet was used to represent the drill rig. Sound PLAN input and output is provided in Appendix D. WELL OPERATION NOISE MODELING Noise levels associated with a worst -case scenario were estimated at the property line of the project site using the Sound PLAN noise model. The intention of the modeling effort was to determine how much noise reduction is necessary i.e., mufflers, concrete walls, acoustical paneling, etc. would be required in order to ensure that well noise will not violate applicable City standards. As stated in the project description, drilling will occur 24 hours a day for several weeks; and the wells will be drilled consecutively, not concurrently. A noise measurement was conducted at a similar facility with the same size pump and was used for modeling purposes (86.6 dB at 3 feet). Noise measurements were also taken outside of the pump house to evaluate how typical building methods work together to attenuate noise associated with the pump One noise measurement was taken outside of each side of the pump house. And although concrete masonry walls are expected to provide approximately 40 dB of sound reduction, there were elements in the wall assemblies that lowered this number as was apparent during noise measurements. For example, the northern wall which was approximately ten -feet from the pump included a closed double door but a few inches of daylight entering from the bottom of the door was noticed. The northern wall had no other readily noticeable openings. It is estimated that the northern wall provides a sound reduction of 18 dB. The western wall had large circulation fans and provided sound reduction of approximately 14 dB; and the eastern wall, which had louvered vents provided a noise reduction of 21 dB. Since only the northern pump was in operation, the sound reduction of the southern wall is irrelevant. The estimated sound reductions calculated for the representative well house were applied to the proposed well house as appropriate in the Sound PLAN noise model. The proposed SoundPLAN input and output is provided in Appendix D. GROUNDBORNE VIBRATION MODELING Per the FTA Transit Noise and Vibration Impact Assessment Manual (2018) drilling has a vibration impact of 0.089 inches per second peak particle velocity (PPV) at 25 feet which is perceptible but below any risk to architectural damage. The fundamental equation used to calculate vibration propagation through average soil conditions and distance is as follows: PPVequipment = PPVref (25/Drec)n Where: PPVref = reference PPV at 25ft Drec = distance from equipment to receiver in ft n = 1.5 (the value related to the attenuation rate through ground) g3rdipl Bushard Street Water Well Project Noise Impact Analysis 19786 4-77 6. NOISE AND VIBRATION IMPACTS This section analyzes the significance of project -related noise and groundborne vibration impacts relative to standards established by the City of Fountain Valley and other applicable agencies in the context of CEQA. Appendix G of the California Environmental Quality Act Guidelines (Title 14, Division 6, Chapter 3 of the California Code of Regulations) includes an environmental checklist that identifies issues upon which findings of significance should be made. NOISE IMPACTS Would the project result in: a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Construction Noise Finding: Less Than Significant (With Recommendation #1) As shown on Figure 6 through Figure 9, construction noise levels will range between range between 44 and 57 dBA Leq at first floor levels of nearby residential properties and between 50 and 57 dBA Leq at second story levels of nearby residential properties; therefore, noise levels at several of the affected receptors would exceed the City's nighttime standard of 50 dBA without the use of noise barriers during construction. The following noise reduction measure is recommended during construction to ensure the project does not exceed applicable nighttime noise standards: Recommendation #1 Prior to commencement of well drilling, the project shall install temporary noise barriers with an STC rating of at least 20 dB around each well drill as illustrated on Figure 10 and Figure 12. The temporary noise barriers should measure 8 feet high along the south, east, and west sides and 12 feet high along the north side of the well drills, and shall remain in place through completion of all well drilling activity. Newer residential structures provide approximately 20 dB of exterior to interior noise reduction. Therefore, unmitigated interior noise levels will range between 22 and 37 dBA Leq and will not exceed the City's interior noise standard of 45 dBA Leq. No mitigation measures would be required with implementation of Recommendation #1 into the project construction plans. Operational Noise Finding: Less Than Significant As shown on Figure 14, operational noise levels will range between range between 36 and 49 dBA Leq at first floor levels of nearby residential properties and between 46 and 56 dBA Leq at second story levels of nearby residential properties. the project site property lines shared with existing single family land uses, The modeling that was conducted to arrive at these sound levels assumes installation of the eight -foot concrete wall shown as shown in Figure 2; and installation of metal acoustical paneling on interior walls of the proposed building similar to what is provided inside of the building at 17399 Magnolia Street. Representative noise data and gndjh Bushard Street Water Well Project Noise Impact Analysis 19786 4-78 photos showing the existing metal acoustical paneling are provided in Appendix C. Impacts would be less than significant and no mitigation is required. As stated above, newer residential structures provide approximately 20 dB of exterior to interior noise reduction. Therefore, unmitigated interior noise levels during project operation will range between 16 and 29 dBA Leq at first floor receptors; and between 26 and 36 dBA Leq at second floor receptors; and will not exceed the City's interior noise standard of 45 dBA Leq. No mitigation is required. GROUNDBORNE VIBRATION IMPACTS Would the project result in: b) Generation of excessive groundborne vibration orgroundborne noise levels? Finding: Less Than Significant In relation to the Environmental Checklist noise issue "b", the City of Fountain Valley has not adopted numerical criteria for groundborne vibration impacts. Therefore, in the absence of City -established thresholds, groundborne vibration impacts are based on guidance from the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (FTA, September 2018) (see Regulatory Setting section). Accordingly, the project may result in a significant impact if it causes groundborne vibration to exceed 0.2 PPV inches/second at nearby offsite structures. Construction -Related Vibration Impacts Proposed well sites are no closer than 58 feet from the project site property line and groundborne vibration associated with well drilling is expected to be approximately 0.025 at that distance. Therefore, well drilling would not result in significant impacts related to groundborne vibration. No mitigation is required. Operation -Related Vibration Impacts The most substantial sources of groundborne vibration during post -construction project operations will include the movement of passenger vehicles and trucks on paved and generally smooth surfaces. Loaded trucks generally have a VdB of 85.6 at a distance of 25 feet (Caltrans 2020), As stated previously, the nearest structure is 50 feet from the proposed alignment. Therefore, groundborne vibration levels generated by project operation would not exceed the City groundborne vibration standard for land uses of 85 VdB at a sensitive receptor. This impact would not be significant. No mitigation is required. AIR TRAFFIC IMPACTS Would the project result in: c) For a project located within the vicinity of a private airstrip or on airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the area to excessive noise levels? Finding: No Impact As the proposed well site is located approximately 5.6 miles northwest of the nearest airport (John Wayne Airport) and is not located within an airport noise contour. The project would not expose people residing or working in the project area to excessive noise levels associated with airports; impacts are less than significant and no mitigation is required. 931dipi Bushard Street Water Well Project Noise Impact Analysis 19786 4-79 �J M ti Signs and symbols Concrete Walls (6 ft) Receiver ' Well Drill Noise Level Tables (dBA, Leq) 51 f st FI12nd Fl i is�iso Figure 6 Construction Noise Levels - North Well Bushard Water Wells Noise Impact Analysis 19786 4-80 Signs and symbols Concrete Walls (6 R) Well Drill Levels in dB(A) a 45 45 - 50 50-55 55 - 60 - 60 - 65 �= 5 g3ldii P .f 0 flo' rA Figure 7 Construction Noise Level Contours - North Well Bushard Water Wells Noise Impact Analysis 19786 4-81 11k. ill �1 Vol 0 L ra Signs and symbols Concrete Walls (6 ft) Receiver Well Drill s 5z Noise Level Ta6ies (dBA, Leq) 'S3 1 st FI12nd Fl 2.5750 g3ldii 774 m m All Figure 8 Construction Noise Levels - South Well Bushard Water Wells Noise Impact Analysis 19786 4-82 + I I- ! . %4-04k e ,• ��'..

A -Weighted Sound The sound level obtained by use of A -weighting. The A -weighting filter de-emphasizes Level, dBA the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear. Community Noise Equivalent Level. CNEL is a weighted 24-hour noise level that is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), CNEL and by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the evening and nighttime hours. A logarithmic unit of noise level measurement that relates the energy of a noise source Decibel, dB to that of a constant reference level; the number of decibels is 10 times the logarithm (to the base 10) of this ratio. Day Night Level. The DNL, or Ldn is a weighted 24-hour noise level that is obtained by DNL, Ldn adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the nighttime hours. Equivalent Continuous Noise A level of steady state sound that in a stated time period, and a stated location, has the Level, Leq same A -weighted sound energy as the time -varying sound. Fast/Slow Meter The fast and slow meter responses are different settings on a sound level meter. The Response fast response setting takes a measurement every 100 milliseconds, while a slow setting takes one every second. Frequency, Hertz In a function periodic in time, the number of times that the quantity repeats itself in one second (i.e., the number of cycles per second). Loz, Los, Lso, L90 The A -weighted noise levels that are equaled or exceeded by a fluctuating sound level, 2 percent, 8 percent, 50 percent, and 90 percent of a stated time period, respectively. Lmax is the RMS (root mean squared) maximum level of a noise source or environment Lmax, Lmin measured on a sound level meter, during a designated time interval, using fast meter response. Lmin is the minimum level. Offensive/ The noise that intrudes over and above the existing ambient noise at a given location. Offending/Intrusive The relative intrusiveness of sound depends on its amplitude, duration, frequency, and Noise time of occurrence, and tonal information content as well as the prevailing ambient noise level. Root Mean Square A measure of the magnitude of a varying noise source quantity. The name derives from (RMS) the calculation of the square root of the mean of the squares of the values. It can be calculated from either a series of lone values or a continuous varying function. 4-94 APPENDIX C NOISE MEASUREMENT FIELD WORKSHEETS 4-95 Noise Measurement Field Data Project Name: Representative Water Well, 17399 Magnolia Street Project, Fountain Valley Date: July 21, 2025 Project #: 19786 Noise Measurement #: STNM Interior Run Time 15 minutes Technician: Ian Edward Gallagher Nearest Address or Cross Street: 17399 Magnolia Street, Fountain Valley, CA 92708 Site Description (Type of Existing Land Use and any other notable features): Project Site: Inside water well pump house, about 3' from main noise , N active water pump.
