This Project comprises two parts; a new transmission pipeline in Yorba Linda Blvd and a new booster pump station in Gun Club Road. A pressure reducing station will be added to pump station replacing the existing facilities at Jessamyn West Park. The new pipeline work corridor will begin at the intersection of Ohio Street and Yorba Linda Boulevard. From this system connection point the new pipeline will travel east along Yorba Linda Boulevard for approximately 2,700 feet to the intersection of Gun Club Road where it will connect to the new pump station approximately 60-ft north of Yorba Linda Boulevard. The new booster pump station will be constructed near the intersection of Gun Club Road and Yorba Linda Boulevard on the City owned property. Upon exiting the station, the alignment continues eastward for approximately 2,000 feet to the Southern California Edison (SCE) easement where a connections to an existing pipeline will be made. The existing booster pump station facilities in Jessamyn West Park will be demolished and the site will be landscaped to match the existing park setting. 1.5 Project Sponsor's Name and Address: Yorba Linda Water District (YLWD) 1717 East Miraloma Avenue Placentia, California 92870 LEE & RO, Inc. ,1 WROJ14881G2 rtenolatcry Correspondorce (CECA)M:QA+YLWI} G£OA July 2011 doc YLWD Booster Pump Station and Pipeline Project Page 2 CEQA - Initial Study/Mitigated Negative Declaration July 2011 1.6 General Plan Designation: The City of Yorba Linda General Plan Land Use Map designates lands within the proposed Project work area as residential (low, medium, and high density), public space (park and elementary school), commercial (neighborhood, general, and office), and unincorporated area. The pipeline portion of the Project will be constructed below grade in the Yorba Linda Blvd. right-of-way adjacent to this land use. The exception is the City owned property on Gun Club Road, which is designated to become a public space. The new pump station will be located within the public park site.

LEE & RO, Inc, 9.5PROPAS'M132 Ren,laiary correspondenco (CFQA)1CFQXYLW0 CEQA July 2,011 dec YLWD Booster Pump Station and Pipeline Project Page 3 L -VA U2 CEQA - Initial Study/Mitigated Negative Declaration July 2011 1.8 Description of Project: YLWD owns and operates a small bump station at the Jessamyn West Park located near the intersection of Yorba Linda Boulevard and Palm Avenue. Constructed in the early 1970s, this pump station is currently rated at 1,250 gpm and feeds hydraulic pressure Zone 3. A pressure reducing station is located adjacent to the existing pump station and is in the center median of Yorba Linda Boulevard. The objective of the Yorba Linda Boulevard Booster Station and Pipeline Project is to deliver lower cost groundwater from the recently completed 6 million gallon (MG) capacity Highiand Reservoir to East Yorba Linda customers. YLWD intends to accomplish this objective by replacing the existing pump station with a larger capacity 5,000 gpm pump station. The single story Pump station will include a new pressure reducing station (Zone 3 to Zone 2 pressure reducing valve) within the pump station site. The new pump station / pressure reducing site will be located on City of Yorba Linda property at 19555 Yorba Linda Boulevard, Yorba Linda, CA 92886 in a strip of land formerly referred to as Gun Club Road. This 150 foot wide strip is planned as a future City park, although a date for the development of the park is not known at this time. The area designated for the pump station will be within a 55-ft x 80-ft easement to be granted by the City. A commercial development with a Bank of America building is located along the eastern property line. An AT&T facility is located on the western side of the easement. The Project also includes approximately 4,700 LF of new 20-inch diameter suction and discharge pipeline along Yorba Linda Boulevard from a Zone 2 connection point at Yorba Linda Boulevard and Ohio Street to a Zone 3 connection point at Yorba Linda Boulevard and the 50- foot Southern California Edison (SCE) easement (east of Fairmont Boulevard). This area of Yorba Linda Boulevard has many existing underground utilities. In addition, the Metropolitan Water District of Southern California (MWD) 120-inch diameter Allan McCulloch pipeline (AMP) runs along the centerline of Yorba Linda Boulevard and turns north through the Gun Club Road 150-foot easement, with the centerline of the AMP located approximately 57 feet from the western property line. The 20-inch diameter Zone 2 water main (suction pipeline) will cross both the 120-inch AMP pipeline and other underground utilities to reach the pump station. The 20-inch diameter Zone 3 water main (discharge pipeline) will only cross the underground utilities and will elbow to the east before reaching the AMP pipeline. In addition, the new pressure reducing station will connect to an existing 12-inch District Zone 3 water main in the west bound lane of Yorba Linda Boulevard, also crossing beneath the underground utilities. Figures 1-2, 1-3, and 1-4 illustrate the new pipeline alignment and location of the replacement pump station. Traditional open cut construction will be used for all portions of the alignment. It is not anticipated that utility agencies will be required to relocate their facilities. Portions of replaced YLWD pipeline segment will be abandoned in place. LEE & RO, Inc.

Topography within the YLWD service area varies from about 200 feet above sea level to a high of about 1,400 feet above sea level. The climate is typical for the coastal plain of Southern California with an average rainfall of 14 inches per year and annual temperatures averaging about 53 degrees Fahrenheit between the years 1948 and 2005 YLWD is an independent special district providing water and sewer service to all of the City of Yorba Linda and portions of the Cities of Brea, Placentia, Anaheim, and unincorporated Orange County. The Population of the YLWD service area was estimated at approximately 80,000 persons with nearly 25,000 water service connections in 2010' YLWD currently has two sources of water supply: 1. Lower Santa Ana Groundwater Basin (Orange County Basin) 2, Metropolitan Water District of Southern California (MWD) (via Municipal Water District of Orange County) or MWDOC Historically, the Yorba Linda Water District has pumped approximately 50% of its total annual water supply from the Lower Santa Ana Basin through groundwater wells. The basin is contained within the Orange County Groundwater Basin, which is managed by Orange County Water District (OCWD). In 1933 OCWD was formed by a special act of the California Legislature to manage Orange County's groundwater supply and protect the County's rights to water in the Santa Ana River. OCWD is responsible for managing the use, replenishment, and protection of Orange County's groundwater basin. A Basin Pumping Percentage (BPP) is set by OCWD that mandates the percentage of groundwater production to total water supply that each of its member agencies, including YLWD, is allowed to pump. The remainder of the water supply required to meet YLWD's demands is imported from MWD via MWDOC. MWD is the largest wholesale water agency in the united States, bringing imported water from the Colorado River via the Colorado River Aqueduct and from Northern California via the State Water Protect, to a water service area that extends from Ventura to the YLWD 2005 Urban Water Management Plans LEE & RO, Inc.

MWDOC was organized to acquire imported water from MWD and supply it to many agencies in Orange County. The YLWD service area can best be described as a suburban residential "bedroom" community. Retail, commercial businesses, which service the predominately suburban population, are located at various points throughout YLWUs service area. No heavy industrial or manufacturing occurs within YLWD boundaries; however, there are several small industrial centers located in the southern and eastern portions of YLWD. Currently about 99 percent of the service area is developed. The pipeline alignment will be located entirely within the developed portions of the City of Yorba Linda and will be located beneath developed public streets. The new booster pump station will replace the existing facility and will be located on City owned property. The YLWD service area, where construction will take place, do riot contain ecologically important vegetation and wildlife habitats; or sensitive plant and animal species. 1.11 Other Agencies: Metropolitan Water District of Southern. California (MWD) Municipal Water District of Orange County (MWDOC) City of Yorba Linda is another local agency of significance in the project area. 1.12 Approval Agencies: The City of Yorba Linda must approve a traffic-control plan and the final construction plan, and issue encroachment permits for the work in public streets and on City property. Both MWD and MWDOC have significant easements and infrastructure that require review of both the proposed pipeline and pump station plans. This review will avoid conflicts with either of their infrastructures; therefore each must be reviewed and approved prior to start of construction.

Although the new station will be located at an alternate site, the existing station site will be landscaped to match the existing park setting. The new pump station building exterior will blend with the surrounding building facilities to avoid aesthetic impacts. The proposed Project pipeline alignment is not located along any designated scenic highway and does not require the removal of any structures or natural features since it is located in fully improved public right-of-way and disturbed urban areas. The Project replaces an existing facility and does not create any new light sources. Implementation of the Project will not impact scenic vistas, damage scenic resources, substantially degrade the existing visual character or quality of the Project area, or create a new source of substantial light or glare, and there will be no impact to aesthetics.

AGRICULTURAL RESOURCES - In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model prepared by the California Department of Conservation as an optional model to use in assessing impacts on agricultural farmland. Would the Project: a. Convert Prime Farmland, Unique Farmland, or Farmland of Statewide lrnportance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring N-A Program in the California Resources Agency, to non- ,_iegricultural use? - b. Conflict with existing zoning for agricultural use, or a Williamson Act contract? k_N c. Involve other changes in the existing environment which, due to their location or nature, could individually or cumulatively result in lass of Farmland, to non-agricultural use? Discussion: A change in land use will not occur as a result of the new pump station and pipeline facilities. The Project therefore will not directly result in the conversion of Important Farmland to non- agricultural use, conflict with existing zoning for agricultural use or a Williamson Act contract, or involve other changes that could result in conversion of Farmland to non-agricultural use, LEE & RO, Inc.

AIR QUALITY - Where available, the significance criteria established by the applicable air quality management or pollution control district may be relied upon to make the following determinations. Would the t roject: - - - a. Conflict with or obstruct implementation of the applicable air duality plan? b. Violate any air quality standard or contribute substantially to an existing or Projected air quality violation? c. Result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is Rion-attainment under an applicable federaf or state ambient air quality standard {including releasing emission which exceeds quantitative thresholds for ozone precursors d. Expose sensitive receptors to substantial pollutant concentrations? T_ e. Create objectionable odors affecting a subsiantial number r~ of people? Discussion: Implementation of the Project will not generate air quality emissions. The Project will not conflict with the AQMD, violate any air duality standard or result in a cumulatively considerable increase in any criteria pollutant, or expose sensitive receptors to substantial pollutant concentrations. Dust which could be created during construction will be mitigated by wetting and the use of tarps. 'The Project will convey potable water and there will be no aspect that will create objectionable odors. The Project's construction related emissions were calculated using the Sacramento Metropolitan AQMD Model 6.3-2, based on the California Air Resources Board's 2007 EMFAC model. Emissions results are compared with significance levels published by the South Coast Air Quality Management District. The results, is shown in Tables 4-1 and 4-2 below, emissions indicate that the Project is unlikely to generate criteria air pollutants exceeding the threshold levels during construction.

GREENHOUSE GAS EMISSIONS - Where available, the significance criteria established by the applicable air quality management or pollution control district may be relied upon to make the following determinations. Wouid the Project. a. Generate greenhouse gas emissions, either directly or El 0 LFENJ ❑ f indirectly, that may have a significant impact on the environment's b. Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? Discussion- The Project may generate additional greenhouse gas emissions as the new facility will require larger electric motor pumps. These large electric motors require an electrical source supplied by Edison's Power Generation Facility.. Though construction of the Project will generate emissions of greenhouse gases, these impacts will only be temporary during the construction activities. Maintenance of the pipeline will be similar to that required by the existing pipeline. There will be no net increase in greenhouse gas emissions for this portion of the Project. Therefore, impacts from greenhouse gas emissions will be less than significant.

YLWD has no discharge permits reguiating water quality and is only regulated with regard to the drinking water quality of distributed potable water. It is the actual use of the imported water and discharge after use (i.e., as wastewater) that has the potential to affect water quality of surface waters. This potential impact was considered in the Los Angeles Regional Water Quality Control Board Water Quality Control Plan (Basin Plan) for the Coastal Watersheds of Los Angeles and Ventura Counties (1994, as amended). implementation of the Project will not directly result in the violation of any water quality standards or waste discharge requirements. The Project will not lead to the depletion of groundwater supplies. The additional pumping capacity realized through the larger pipeline segment and new pump station is to deliver groundwater with the intention of scaling back on water purchased from MWDOC. The amount of groundwater available for use is strictly regulated by the Orange County Water District (OCWD) as they are responsible for managing the use, replenishment, and protection of Grange County's groundwater basin. A Basin Pumping Percentage (BPP) is set by OCWD that mandates the percentage of groundwater production to total water supply that each of its member agencies, including YLWD, is allowed to pump. The Project will not interfere with groundwater recharge or alter any existing drainage pattern, create or contribute runoff water, or serve as a source of polluted runoff since the ground surface will be restored after construction. There is no aspect of the Project that will otherwise substantially degrade water quality. The Project will not construct any housing or above ground structures within a 100-year flood hazard area or expose people or structures to a significant risk of loss, injury, or death involving flooding; or result in inundation by seiche, tsunami, or.mudflow.

The new facility site has been developed previously. Thus, implementation of the Project will not require the construction of new (net) facilities, or any other land disturbance or change in land use, The Project occurs within the fully developed portions of the City of Yorba Linda. The Project will not require the use of mineral resources once constructed nor prevent access to ground based mineral resources. The Project, therefore, will not result in the loss of availability of a known mineral resource that will be of value to the region and the residents of the state-, or result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan.

The Project will temporarily generate noise as a result of pouring concrete, building construction, installing mechanical equipment, construction equipment digging trenches, installing pipe, backfilling, asphalt replacement, and street work. During construction the Project will temporarily expose persons to or generate noise levels in excess of ambient noise levels, but does not involve pile driving or other construction techniques that will generate or expose persons to ground-borne vibration or ground-borne noise levels. The project requires the use of equipment only briefly in a given area as the pipeline will be constructed at a rate of at least 100 feet per day resulting in noise impacts only briefly in a given area. The pump station work will be bordered on one side by a commercial area- Limiting that work to daytime hours consistent with the City of Yorba Linda's noise ordinance will keep construction related noise impacts to a less-than-significant level. The Project will not involve construction located within an airport land use plan, within two miles of a public airport, or in the vicinity of a private airstrip. During operation, after construction is complete, the pipeline and replacement pump station (includes acoustical louvers, door seals, and a parapet surrounding the roof-mounted exhaust fan) wijl not have any noise generating features that expose persons to noise levels above existing operational standards established in the local general plan, noise ordinance, or applicable standards of other agencies. Thus impacts from noise will be less than significant. LEE & RO, Inc.

MANDATORY FINDINGS OF SIGNIFICANCE a. Does the Project have the potential to degrade the duality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop Q below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory? b.

Does the Project have environmental effects which will cause substantial adverse effects on human beings, either direetty or indirectly? _ _ - - Discussion. a) The Project does not have the potential to temporarily degrade the quality of the environment; temporarily impact habitat of fish or wildlife species, threaten to temporarily impact a plant or animal community; restrict the range of a rare or endangered plant or animal. The Project will not have significant impacts to examples of California history or prehistory as documented in the Cultural Resources Section of the Initial Study. b) The Project will have less-than-significant temporary impacts during construction, which wT not be cumulatively considerable in combination with those of other Projects due to the localized and temporary nature of the impacts documented in the Initial Study. This, includes potential impacts from other development Projects and water supply Projects. The Project will have a beneficial impact to YLWD's water customers, because it will deliver lower cost groundwater and reduce the demand for surface water originating from the Colorado River Once completed, the Project will allow the Pipeline to function at increasers capacities compared to the existing line. The improvement in local system water capacity will not constitute the rernovai of an obstacle to growth, as the increase one supply will be offset by reduction in another, thereby indirectly inducing population growth and cumulative impacts. Therefore, the Project will not result in a significant cumulative impact. c) fused on the analysis of the Project's impacts in the other categories of the Initial Study Checklist the Project's impacts, there will be less-than-significant temporary impacts during construction and there will be no impacts during operation that will cause substantial direct or indirect adverse effects on human beings. The Project will result in less than significant temporary impact to air quality; greenhouse gas emissions noise; and transportation/traffic during construction. The Project will not impact hazards and hazardous materials and utilities and service systems. Therefore, there will not be any substantial adverse direct or indirect effects on human beings.

BOOSTER PUMP STATION AND PIPELINE (PROJECTS) Construction of the two Projects is expected to begin in spring of 2012. The pipeline project will occur first and is expected to follow a six month construction schedule. The pump station project will follow, where a nine month construction schedule is anticipated. Pipeline construction work will occur, weekdays between the hours of 9 a.m. and 3 p.m. and the Pump Station construction hours will be weekdays between the hours of 7 a.m. and 4 p.m. Once constructed, the pipeline will not have any associated impacts as it will be located completely underground and will require only that current service operations for the existing pipeline be continued at the new pipeline existing right-of-way. The new booster pump station will replace the existing facility on City-owned land. Traffic: During construction of the Pipeline Project temporary modification of vehicle traffic patterns in Yorba Linda Blvd. will be required within the specific work areas. A traffic control plan will be prepared and submitted to the City of Yorba Linda for approval prior to Pipeline Project construction and will be implemented in areas where the Pipeline Project will be in public streets to mitigate adverse impacts. At least one lane closure during pipeline construction will be required. No traffic detours are proposed. Lane closures will be limited. During construction of the Pump Station Project there will be no impact to traffic in Yorba Linda Blvd. Construction announcements will be sent out to notify the public of the construction and to encourage considering alternate routes. Biological Monitoring Not Anticipated: Construction and completion of this Project will not require undeveloped land disturbance or change in land use in any area that is biologically sensitive. The Project will not directly adversely affect candidate, sensitive, or special status species, riparian habitat or other sensitive natural communities, or federally protected wetlands; interfere with the movement of any fish or wildlife species or impede the use of native wildlife nursery sites; conflict with any local policies or ordinances protecting biological resources; or conflict with the provisions of an adopted Habitat Conservation Plan (HCP), Natural Communities Conservation Plan (NCCP), or other approved, local, regional, or state habitat conservation plan, Cultural Monitoring Not Anticipated: The new pump station will be located at an alternate previously disturbed site, while the existing station site will be cleared and landscaped to match the existing park setting. Thus, implementation of the Pump Station Project will not require the grading of undisturbed native soils or other land disturbance in an area that might contain artifacts. The Pipeline Project will be located on/in fully improved streets and in previously graded and disturbed areas. No structures will be directly impacted by either project's construction. Therefore, the Projects will not directly cause a substantial adverse change in the significance of historical or archaeological resources, directly or LEE & RO, Inc. IN Yorba Linda Blvd. Booster Pump Station and Pipeline Project Page 2 Mitigation Monitoring and Reporting October 2011 indirectly destroy a unique paleontological resource or site or unique geologic feature, or disturb any human remains. If human remains are discovered, the Owner shall immediately notify the Orange County Coroner's office under state law (California Health and Safety Code § 706(7.5) and all activities in the immediate area of the find must cease until appropriate and lawful measures have been implemented. If the Coroner determines that the remains are Native American, the Coroner shall contact the NAHC (California Public Resources Code § 5097.98). The NAHC will designate a Most Likely Descendent who will make recommendations concerning the disposition of the remains in consultation with the lead agency and Project archaeologist. Noise: During construction of the pipeline and replacement pump station, there will be a temporary or periodic increase in ambient noise levels that can be mitigated using good construction practices. Both projects will temporarily generate noise as a result of pouring concrete, building construction, installing mechanical equipment, construction equipment digging trenches, installing pipe, backfilling, asphalt replacement, and street work. The Pipeline Project requires the use of equipment only briefly in a given area as the pipeline will be constructed at a rate of approximately 100 feet per day resulting in noise impacts only briefly in a given area. The pump station work will be bordered an one side by a commercial area. Limiting that work to daytime hours consistent with the City of Yorba Linda's noise ordinance will keep construction-related noise impacts to a less-than-significant level. Both projects will not involve construction located within an airport land-use plan, within two miles of a public airport, or in the vicinity of a private airstrip. During operation, after construction is complete, the replacement pump station (which includes acoustical louvers, door seals, and a parapet surrounding the roof-mounted exhaust fan) will not have any noise-generating features that expose persons to noise levels above existing operational standards established in the local general plan, noise ordinance, or applicable standards of other agencies. Thus impacts from noise will be less than significant. The City of Yorba Linda has a noise ordinance to restrict noises to nearby residences. Section 8.32.060 of the City's Municipal Code makes it unlawful for any person to create any noise which causes the noise level measured on any residential property to exceed the following: Noise Level Shall Not Exceed More Than Day Time Night Time 30 minutes in a hour 55 dBA 50 dBA 15 minutes in a hour 60 dBA 55 dBA 5 minutes in a hour 65 dBA 60 dBA 1 minute in a hour 70 dBA 65 dBA An period of time 75 dBA 70 dBA LEE & R0, Inc.
