The project site is an existing reservoir site located in both the City of San Juan Capistrano and unincorporated Orange County along a one -mile section of the Ortega Highway; and, WHEREAS, the proposed project has been processed pursuarntto Section 9-2.337, Public Improvement Plans and Outside Agency Development Review of the Land Use Code; and, WHEREAS, the Environmental Administrator has reviewed the initial study prepared pursuant to Section 15063 and 15064 of the CEQA Guidelines; has determined that the project qualifies for issuance of a Mitigated Negative Declaration (MND), has issued a Negative Declaration pursuant to Section 15070 of those guidelines; and has caused a Notice of Negative Declaration to be posted pursuant to Section 15072 of those guidelines. Furthermore, the City has mailed a "Notice of Intent to Adopt a Mitigated Negative Declaration" by first-class mail to all parties who had previously requested to be included on the mailing list. The City has otherwise complied with all applicable provisions of the California Environmental Quality Act (1970) and all recommended mitigation measures have been incorporated herein; and, WHEREAS, The "San Juan Capistrano Ortega Highway Pipeline Project Initial Study/Mitigated Negative Declaration"was made available for public review and comment pursuant to the California Environmental Quality Act (CEQA) Guidelines (Section 15073) for a period of 30 days, commencing on December 26, 2007, and ending on January 26, 2008; and during this review period, the City received several comment letters; and, WHEREAS, The City has prepared responses to the comments concluding that no additional significant impacts requiring revisions to the Initial Study were identified; NOW, THEREFORE, BE IT RESOLVED that the City Council hereby makes the ' following findings based on substantial evidence in the record with respect to compliance with the provisions of the California Environmental Quality Act: Page 1 of 5 08-03-2008 0 Section 1. — Pursuant to California Environmental Quality Act (CEQA) Guidelines §15074, the Initial Study/Mitigated Negative Declaration (ISIMND) considers all potentially significant environmental effects of the proposed project and is complete and fully complies with all requirements of CEQA and the Guidelines; and, Section 2. The project would not result in significant impacts to aesthetics. Section 3. The project would not result in significant impacts to agricultural resources. Section 4. The project could result in potentially significant air quality impacts as a result of construction -related emissions. However, the following proposed mitigation measures will reduce such impacts to a level of insignificance: AQ -1 Implement the following to minimize air emissions: • Water sufficiently to reduce off-site transport of fugitive dust from all unpaved staging areas and unpaved road surfaces. • Cover all trucks hauling soil, sand, and other loose materials, • All paved access roads, parking areas, and staging areas shall be swept as -- needed, and daily when soils, sand, and other loose materials are being hauled on or off the site, using SCAQMD Rule 1186 certified water sweepers or recommended water sweepers using reclaimed water. • All construction equipment shall be property tuned and maintained in accordance with manufacturer's specifications. Adherence to SCAGMD Rules 431.1 and43f.2, which require the use of low sulfurfuel for stationary construction equipment. Section 5. The project could result in potentially significant impacts to biological resources as a result of project construction. However, the following proposed mitigation measures will reduce such impacts to a level of insignificance: 8104 The following mitigation measures would reduce potential impacts to biological resources. • Construction equipment shall avoid entering the creek banks and drainage area. The City shall coordinate with Caltrans to identify and comply with construction restrictions during bird nesting season. _ Page 2 of 6 06-03-2006 The City shall ensure that preconstruction bird surveys are conducted within 14 days prior to the start of construction activities during the nesting season (February 1 to August 31). If active nests are found during preconstruction surveys, the City shalt comply with Caltrans' mitigation requirements for providing adequate non -disturbance buffer around active raptor nests and other nesting birds until it is determined that all young have fledged. The size of individual buffers can be adjusted based on an evaluation of the site by a qualified biologist. Site evaluations and buffer adjustments would be done in consultation with the local California Department of Fish and Game representative. If preconstruction surveys indicate that nests are inactive or potential habitat is unoccupied during the construction period, no further mitigation is required. Section S. The project could result in potentially significant impacts to cultural resources as a result of project construction. However, the following proposed mitigation measures will reduce such impacts to a level of insignificance: CR -1 The following mitigation measures will be utilized to avoid negative impacts to cultural resources: The contract specifications shall require the City's contractor to retain the services of a RPA (Register of Professional Archeologists) -certified ' archeologist who will monitor all grading and excavation for potential impacts on cultural resources including archeological, paleontological, and historic resources. The contractor shall provide an executed contract for services with an RPA -certified archeologist including a scope -of -work which provides for comprehensive monitoring; a contingency for assessment, recovery, and/or evaluation; and the preparation of a technical memoranda or report. If historic and/or cultural resources are encountered during grading and/or building activities, the monitoring RPA archeologist may cease any grading and/or building construction activities, subject to confirmation by the City's Environmental Administrator (EA), to allow for preliminary assessment, evaluation of any cultural resources, and/or recovery. The archeological monitor or Environmental Administrator (EA) may allow grading activity to proceed at other locations on the project site which would not interfere with the assessment of uncovered cultural resources. Prior to completion of the project the contractor shall assure that the archeological monitorsubmits a technical memorandum orcultural resources report which details archeological monitoring efforts, findings, analysis, and conclusions consistent with City Council Policy #601 and subject to review and approval of the Planning Director. ' • If human remains are encountered, the City shall halt work in the vicinity of the rind and contact the county coroner in accordance with Public Resources Page 3 of 6 06-03-2008 0 0 Code Section 5097.98 and Health and Safety Code Section 7050.5. If the _ coroner determines the remains are Native American, the coroner shall contact the Native American Heritage Commission (NAHC). As provided in Public Resources Code Section 5097.98, the NAHC shall identify the person or persons believed to be most likely descended from the deceased Native American. The most likely descendent makes recommendations for means of treating or disposing of, with appropriate dignity, the human remains and any associated grave goods as provided in Public Resources Code Section 5097.98. Section 7. The project could result in potentially significant geology and soils impacts related to erosion and sedimentation as a result of construction -related activities. However, the following proposed mitigation measure will reduce such impacts to a level of insignificance: Implement Mitigation Measure WQ-1. Section 8. Impacts to hazards and hazardous materials would be less than significant as large quantities of potentially hazardous materials would not be present at the construction site, no hazardous materials would be routinely used during the operation of the pipeline, no above ground structures would be constructed and all vegetation would be removed before construction activities begin. Section The project could result in potentially significant hydrology and water quality impacts related to erosion and sedimentation as a result of construction -related activities. However, the following proposed mitigation measures will reduce such impacts to a level of insignificance: WQ-1 The City shall require that contractors comply with Best Management Practices (BMPs) for erosion and sedimentation control identified in Caltrans' SWPPP for the roadway project. Section 10. The project would not result in impacts to land use and planning. Section 11. The project would not result in impacts to mineral resources. Section 12. The project could result in potentially significant noise impacts related to construction activities. However, the following proposed mitigation measures will reduce such impacts to — a level of insignificance: Page 4 of 6 06-03-2008 0 9 NOH Noise sources associated with construction, repairs, remodeling, or the grading ' of any real property shall be limited to 7:00 a.m. to 6:00 p.m, on Monday through Friday, and from 8:30 a.m. to 4:30 p.m. on Saturday. Construction is prohibited all day Sunday and on Federal holidays. NOI-2 Equipment and trucks used for project construction shall utilize the best available noise control techniques (e.g., improved mufflers, equipment redesign, use of intake silencers, ducts, engine enclosures and acoustically -attenuating shields or shrouds, wherever feasible). Section 13. Impacts to population and housing would be less than significant as the proposed project would not directly contribute to the creation of additional housing or jobs because the project is limited to the provision of water supply infrastructure. Section 14. The project would not result in impacts to public services. Section 15. The project would not result in impacts to recreation. Section 16. ' Impacts to transportation and traffic would be less than significant as the traffic generated by the pipeline installation activities would be minor compared to the overall impact of the road widening project and impacts would be relatively brief. The construction crew would not require a significant number of parking spaces. The City would be subject to Caltrans emergency access and traffic control plans. After construction of the project, all transportation impacts would cease. Section 17. Impacts to utilities and service systems would be less than significant as solid waste generation would be limited to construction activities, and would not affect available solid waste disposal capacity in the region. Section 18. Impacts of mandatory findings of significance would be less than significant as the project would not degrade the quality of the environmental. Any environmental impacts would be limited to short-term construction impacts and would be reduced to a less -than -significant level by the above mitigation measures. NOW, THEREFORE, BE IT FURTHER RESOLVED, that the City Council of the City of San Juan Capistrano does hereby recommend adoption of a Mitigated Negative Declaration subject to the mitigation measures contained herein.

Approve County Change Order No. 14 in the amount of $44,174.15 to the Contract with Griffith Company through the contract for contract management services with the County of Orange; and authorize the City Manger to sign the County's Change Order No. 14 to Agreement D08-102 pertaining to the City's portion of the project as defined by Contract D08-050 between the County of Orange and San Juan Capistrano; and 3. Ratify the Amendment of May 7, 2009, to Contract D08-050 with the County of Orange for Construction Management Services reducing the deposit amount due from $675,000 to $500,000. SITUATION: At its meeting of June 20, 2006, City Council approved a contract for design services with HDR Engineering, Inc. for the Ortega Highway 12 -inch Pipeline, Project E1 of San Juan Capistrano's March 2004, Domestic Water Master Plan (CIP# 754, now CIP #07804). At its meeting of June 3, 2008, Council approved the adoption of the Mitigated Negative Declaration (MND) for this project, and entered into County Contract Agreement No D08-050 (Attachment 1) to have the County act as Contract Administrator and Contract Manager. The County solicited and received seven competent bids on October 29, 2008. Attachment 2 shows the specific breakdown on the costs relevant to the City's cost for the pipeline, and the total contract bid. The lowest total bid was that of Griffith Company Agenda Report • • Page 2 October 20, 2009 at $21,202,993 to which the County subsequently awarded the contract. On a comparison of the bids for just the items of work, including a proportional share of the general conditions and insurance, Griffith was the middle at $475,731, with a high bid of $781,757 by Brent Engineering Inc (total bid $27,621,029), and a low bid of $414,070 by Palp Inc (total bid $28,418,014.) The City's options were to withdraw the pipeline project and seek an alternate means of construction of pipeline or to go with the cost of $474,731 included in the projects low total bid by Griffith Company. The City did not withdraw, seeing no alternative means of construction that would not result in higher end cost given the cost impacts of traffic control on a Caltrans roadway, pavement removal and repair, environmental monitoring, and SWPPP implementation; estimated to be in excess of $100,000. Staff recommends that Council ratify the contract by the County with Griffith at the bid price of $475,731 for the City's portion of the work. In December 2008, the design engineers, HDR, issued a change to the design details and specifications. HDR claimed the changes were not included with the bid package because Caltrans had not completed its plan check in time. The changes included the addition of flexible couplings to the pipe just before and after it crosses the San Juan Creek bridge, the use of rolling bearings on the bridge compliant with Caltrans specifications, increasing the number of rolling bearings, increasing the thickness of the pipe in the bridge, deletion of the concrete coating in the bridge section, and changing the pressure class of the blow offs to that commensurate with that of the pipeline. Griffith submitted a cost change increase for these changes totaling $44,174.15. The changes were necessary and unavoidable. Staff evaluated the request and determined that the costs changes were reasonable, and that sufficient credit had been issued for the deleted items. Staff recommends that City Council approve the contract cost change for an increase in the amount of $44,174.15; and that the Council authorizes the Acting City Manger to sign the County's Change Order No. 14 to Agreement D08-102 pertaining to San Juan's portion of the project as defined Contract D08-050 between the County of Orange and San Juan Capistrano (Attachment 3.) Given that the bid for the pipeline work was significantly lower than the estimate in agreement D08-050 with the County, Staff requested that the County lower the deposit amount specified in section II (C) from $675,000 due with in 30 days of the award of contract (January 2009) to $500,000 due upon receipt of invoice. The agreement was made between the County and the City on or about May 7, 2009 (Attachment 4). The invoice was paid shortly thereafter. Staff recommends that the Council ratify the Amendment of May 7, 2009 to Contract D08-050 with the County of Orange for Construction Management Services reducing the Deposit Amount due from $675,000 to $500,000. Agenda Report • • Paae 3 October 20. 2009 FINANCIAL CONSIDERATIONS Originally, projects E1, the Ortega Hwy Pipeline and E8 the Rancho Viejo 16" line were in the same budget CIP #755 (now CIP 07804) in fiscal year 2005/06, as both were intended to be completed at the same time, with the same engineer and contractor. E1 was delayed as it became apparent that the Ortega Hwy project widening was in planning and coordination could facilitate design, construction, and land acquisition issues. E8 was then constructed jointly with a 12" recycled water line in Rancho Viejo as the two projects shared a common area of design and construction. E8 was completed in 2006, costing $328,825 and leaving $816,175 in the budgeted amount for project E1 (lines 2, 3, 4, and 5). The current design contract covers the whole project however the construction and construction management contracts cover only the East two thirds (lines 8 — 14.) Note that Change Order #14, line 12, is currently under consideration. When the Ortega Hwy re -alignment is extended in to San Juan Capistrano, the design for the West third of the project will be completed, and the pipeline, including a pressure reducing valve to serve the Shade Tree Lane area (line 16) will be constructed (lines 15-18). If the remaining Ortega Highway work does not occur or is delayed permanently, the completion of this line will have to occur within the right of way of the existing highway at a greater expense than could be accomplished with integrated construction. The current budget for E1 will have sufficient funds to complete the East two thirds of the pipeline. The cost of a claim by the design engineers HDR has been included for budget analysis as line 17. HDR claims that it should receive payment for cost over runs incurred which Staff considers unjustifiable. The matter is currently under review by the City Attorney's office for possible resolution. The current projection of budget surplus or deficit for the project (line 22) is for a deficit. Given that no additional costs against the contingency (line 14) seem forthcoming from the east side pipeline, and that the HDR claim (line 19) will settle for much less, the projected balance (line 14) of the eastern 2/3rds of the pipeline does not warrant additional funding at this point. When the timing and costs of the western 1/3`d of line E1 are better defined, Staff will make a recommendation for budget transfer of funds for the completion of project E1; which not including consideration for the HDR claim are estimated at $495,000 based on the costs for the eastern portion.

This agreement provides for the County to include Facilities Installation for the City in the construction contract to widen a portion of Ortega Highway (SR 74). Said agreement also provides for the City to deposit with the County $675,000 for the estimated cost of Facility Installation. The amount of $675,000 was based on the Engineer's Estimate for the Facility Installation. However, the actual contract bid amount for said Facility Installation is approximately $500,000. Therefore, pursuant to Section 'F' of the subject agreement the parties hereby agree that the City shall deposit with the County the amount of $500,000 instead of $675,000 for the estimated cost of the Facility Installation. All other terms of the subject agreement remain unchanged. An invoice for $500,000 is attached for said amount. By way of this letter I am recommending your concurrence to the above changes.

SITUATION: At its meeting of June 2006, the City Council approved a contract for design services with HDR Engineering, Inc. for the Ortega Highway 12 -inch Pipeline, Project E1 of San Juan Capistrano's Domestic Water Master Plan (CIP# 754). The March 2004 Domestic Water Master Plan, adopted by the City Council on May 18, 2004, includes the Ortega Highway Pipeline project as project E1. Completion of the pipeline design had been delayed in order to coincide with the completion of the Ortega Highway design. Currently, Caltrans and the County have completed the design of the eastern portion and have agreed to construct the eastern two-thirds of its planned expansion to Ortega Highway, between Antonio Parkway and Toyon Drive. The remaining portion of the roadway will be constructed when the environmental impacts on that portion are adequately mitigated. If the remaining Ortega Highway work does not occur or is delayed, the completion of this line will have to occur within the right of way of the existing highway at a greater expense that could be afforded with integrated construction. The Environmental Administrator has reviewed the initial study prepared pursuant to Section 15063 and 15064 of the CEQA Guidelines; and he has determined that the project qualifies for issuance of a Mitigated Negative Declaration (MND); the AGENDA REPORT • • June 3, 2008 Paqe 2 Administrator has issued a Negative Declaration pursuant to Section 15070 of those guidelines and has caused a Notice of Negative Declaration to be posted pursuant to Section 15072 of those guidelines on December 26, 2007. The MND includes mitigation measures to address the project's potential air quality, water quality, noise, and cultural resource impacts. The Draft Mitigated Negative Declaration for the proposed project was made available for public review and comment pursuant to the CEQA Guidelines, Section 15073 for a period of 30 days, commencing on December 26, 2007, and ending on January 26, 2008. The City has prepared responses to the comments concluding that no additional significant impacts requiring revisions to the Initial Study were identified. Staff recommends adoption of the Mitigated Negative Declaration (Attachment 5) for the Ortega Highway 12 -inch Potable Line. The County of Orange will act as Construction Manager for the construction of the roadway, the widening of the Ortega Highway Bridge at the San Juan Creek. They will ensure compliance with the environmental impact monitoring, reporting, and mitigation measures related to the roadway and bridge construction, related drainage facilities for the roadway, water line crossings designed for the Santa Margarita Water District, and other utility relocations or capital expansions. It makes sense to have the County act as the project manager to cover the bidding, construction oversight, and implementation of the MND measures for the construction of the water line. The County will perform this work for a flat fee to 15% of the construction cost of the line, based on the bid, plus or minus the value of any change orders which occur. The agreement has provisions to terminate the arrangement if, in the joint opinion of the County and the City, the bid price for the pipeline work was insufficiently competitive. Staff recommends approval of this Contract (Attachment 3). HDR Engineering Inc. (HDR) has completed design drawings and construction specifications for the work related to the eastern portion of the pipeline for bidding and construction purposes. Staff has reviewed these drawing at the 50%, 90%, and now the 100% stage of the design process, (Attachment 4.) Staff recommends approval of the plans and specifications for bidding. COMMISSION/BOARD REVIEW AND RECOMMENDATIONS: The Water Advisory Commission will be updated on these projects at their May 27, 2008 meeting. FINANCIAL CONSIDERATIONS: The budget for CIP# 754 included funds for DWMP projects E1 and E8, the Ortega Highway 12 -inch Potable Pipeline and the 16 -inch Domestic Pipeline, constructed in coordination with the Recycled Water Supply Line project totaling $1,143,000. The recently bid High West Side line project (CIP# 793) DWMP projects E12A, E12B, E12C, and E20, have, due to recently dropping and increasingly competitive bids and cost AGENDA REPORT • • June 3, 2008 Page 3 savings, realized through cost analysis conducted in the design process, to have a budget surplus of $450,000. Staff proposes to transfer this to CIP 754 to provide $1,593,000 in funding for CIP# 754. Project E8, the RWSS, cost $313,000, leaving $1,280,000. The design, construction, and construction management of the eastern half of the Ortega Hwy pipeline is expected to cost $927,000, leaving a balance of $353,000. The western half of the Ortega Hwy pipeline is projected to cost $411,000, leaving a shortfall of $58,000. Staff will recommend a budget adjustment for Council's consideration if needed when the bid results are received. NOTIFICATION: County of Orange -Harry Persaud, Mgr. Infrastructure Subdivision RECOMMENDATION: By motion, 1) Adopt a resolution approving adoption of the Mitigated Negative Declaration for Ortega Highway 12 -inch Potable Line (CIP# 754); and, 2) Approve the Contract with the County of Orange to Perform Construction Management Services for the 12 -inch Potable Line; and, 3) Approve Plans and Specifications for Bid.

To accomplish this, if air valves or hydrants or other outlets are 37 not available, taps shall be made at the high points to expel the air, and these taps shall be tightly 38 plugged afterwards. 39 C. After the pipeline has been filled and allowed to sit a minimum of 24 hours (48 hours for mortar - 40 lined pipelines), the pressure in the pipeline shall then be pumped up to the specified test 41 pressure. If a large quantity of water is required to increase the pressure during testing, 42 entrapped air, leakage at joints, or a broken pipe can be suspected. TESTS SHOULD BE 43 DISCONTINUED until the source of trouble is identified and corrected. 42551 City of San Juan Capistrano Ortega 12 -Inch Waterline -520/2008 15042-2 D. When the testpressurehas been reached, the pumping shall be discontinued until the pressure in the line has dropped 30 psi, at which time the pressure shall again be pumped up to the specified test pressure. This procedure shall be repeated until four hours have elapsed from the time the specified test pressure was first applied. At the end of the four-hour period, the pressure shall be pumped up to the test pressure for the last time. 6 E. The leakage shall be considered as the total amount of water pumped into the pipeline during the 7 four-hour period, including the amount required in reaching the test pressure for the final time. 8 Leakage shall not exceed the rates in the tables below. If the size, pipe material, or pressure fall 9 outside of the table listed below, the County of Orange/City Engineer will determine the leakage 10 amount. II 12 13 F.

Description of project: San Juan Capistrano Ortega Highway Pipeline Project (Project No. 207273) City of San Juan Capistrano 32400 Paseo Adelanto San Juan Capistrano, CA 92675 Eric Bauman, (949) 487-4312 Ortega Highway (Highway 74) right-of-way approximately between Toyon Drive and Antonio Parkway. City of San Juan Capistrano 32400 Paseo Adelanto San Juan Capistrano, CA 92675 Suburban Residential, Open Space and Urban Activity Center Medium Low Density, Very Low Density and Open Space Recreation Single -family -10,000, Residential/Agriculture and Open Space Recreation The proposed project consists of the construction of approximately 5,287 linear feet of 12 -inch diameter potable water main pipeline within the Ortega Highway right-of-way. The pipeline would be installed during the proposed widening of the Ortega Highway, currently under consideration by the California Department of Transportation (Caltrans). By installing the pipeline during Caltrans' construction period, the City would minimize direct impacts of the project and avoid the need to disrupt the street in the future. The project would increase the reliability and quality of service within the existing water distribution system to adequately serve existing users, and to meet increasing fire safety demands. The pipeline would be constructed within the paved roadway at depths ranging from approximately 4 to 5 feet below the existing surface. The project is anticipated to include trenching excavation, pipeline installation, backfilling, compacting, and soil replacement all within the construction zone of the Caltrans road widening project. 9. Surrounding land uses and setting: The project site is located in both the City of San Juan Capistrano and unincorporated Orange County along a one -mile section of the Ortega Highway (refer to Figure 1). The western edge of the project begins approximately at the intersection of Toyon Drive and the Ortega Highway in the City of San Juan Capistrano and continues to the east just beyond the intersection of the Ortega Highway and Antonio Parkway in unincorporated Orange County. This section of the Ortega Highway passes through multiple use lands including residential, rural residential, open space, agricultural and commercial lands (refer to Figure 2). 10.

A MITIGATED NEGATIVE DECLARATION will be prepared. ❑ I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. ❑ I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. ❑ I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. Signature William A. Ramsey, AICP, Environmental Administrator Date City of San Juan Capistrano San Juan Capistrano Ortega Highway Pipeline Project 4 ESA 1207273 Initial Study I Miggatetl Negative Declaration December 2D07 0 EVALUATION OF ENVIRONMENTAL IMPACTS: 1) A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project -specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project -specific screening analysis). 2) All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3) Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. 'Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more 'Potentially Significant Impact" entries when the determination is made, an FIR is required. 4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analyses," may be cross-referenced). 5) Earlier analyses may be used where, pursuant to the tiering, program FIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this case, a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site- specific conditions for the project.

Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7) Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. 9) The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance. Issues Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact I. AESTHETICS — Would the project: a) Have a substantial adverse effect on a scenic ❑ ❑ ❑ vista? b) Substantially damage scenic resources, including, but not limited to, trees, rock ❑ ❑ ❑ outcroppings, and historic buildings within a stale scenic highway? c) Substantially degrade the existing visual ❑ E] 1:1character or quality of the site and its surroundings? d) Create a new source of substantial light or El El Elglare which would adversely affect day or nighttime views in the area? 1.1 Significance Criteria The proposed project would result in significant adverse aesthetic impacts if any of the following occur: • Changes at the site substantially degrade the character of the site, degrade an existing public viewshed, or alter the character of a public viewshed by the introduction of anomalous structures or elements. • Changes at the site would result in changes in the expectations of viewers (measured against the relative importance of those views) and would result in a negative San Juan Capistrano Ortega Highway Pipeline Protect 6 ESA 120]2]3 Initial Study I Mitigated Negative D taxation December 2007 0 Checklist impression of the viewshed. (The emphasis of this criterion is on views from public areas, not views from individual lots unless view easements are involved). • Changes at the site substantially conflict with or do not uphold the scenic and visual quality objectives for development, as articulated in the goals, objectives, and policies of the San Juan Capistrano or Orange County General Plan. 1.2 Analysis Would the project. a) Have a substantial adverse effect on a scenic vista? Project Impact — No Impact Based on the San Juan Capistrano General Plan, Land Use Element (City of San Juan Capistrano, 1999), and County of Orange General Plan, Land Use Element (County of Orange, 2005), there are no designated scenic vistas or designated view corridors in the project area. The proposed project would include the construction of approximately 5,287 linear feet of 12 -inch potable water main pipeline within the Ortega Highway right-of-way. The project does not include any surface structures other than minor pipeline appurtenances. There would be no visual impact to scenic vistas. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? Project Impact — No Impact According to the state Department of Transportation's Scenic Highway Program listing, the Ortega Highway is "Eligible" for listing as a Designated Scenic Highway, but is not yet "Officially Designated" (Caltrans, 2007). Official scenic highway status places no restrictions for making improvements on scenic highways, nor does it preclude development. However, Caltrans works with appropriate agencies to coordinate transportation proposals and maintenance activities and to ensure the protection of scenic corridors to the maximum extent feasible. The corridor protection program seeks to encourage quality development that does not degrade the scenic value of the corridor. The pipeline would be installed during Caltrans' proposed widening of the Ortega Highway. The project does not include any surface structures other than minor pipeline appurtenances. In addition, the construction footprint of the pipeline project is not expected to exceed the boundaries of the widening project footprint. As such, any impact to the viewshed caused by the pipeline project would be temporary and would be less than the impact of the widening project. Finally, because Caltrans is the lead agency on the widening project and the lead agency for the Scenic Highway designation, any impact to the scenic highway status would be handled by Caltrans. Therefore, the proposed project would not result in damage to scenic resources within the viewshed of a state -designated scenic highway. c) Substantially degrade the existing visual character or quality of the site and its surroundings? San Juan CaplArano Ortega Kghway Pipeline Project 7 ESA/207273 Initial Study / Mitlgatetl Negative Declaration December 2007 0 0 checklist Project Impact — No Impact Construction activities would require the use of heavy equipment and storage of materials at construction sites. During construction, excavated areas, stockpiled soils, and other materials within the construction easement and staging areas would constitute negative aesthetic elements in the visual landscape. However, these effects would be temporary during project construction. Following construction, the proposed pipeline would be located below -ground. Surface restoration would involve paving the roadway and re -vegetation of the shoulder and construction areas. The project would not include any surface structures other than minor pipeline appurtenances. Therefore, the proposed project would not substantially impact or degrade the existing visual character or quality of the site and its surroundings. d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Project Impact— No Impact The proposed project would be completely underground, other than minor appurtenances, and would not include the use of any material that may create light or glare. The project does not propose outdoor lighting. No impact would occur. Less Than Significant Potentially with Significant Mitigation Impact Incorporation II. AGRICULTURE 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 (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. Would the project Less Than Significant Impact No Impact a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the ❑ ❑ ❑ Farmland Mapping and Monitoring Program of the Califomia Resources Agency, to non- agricultural use? b) Conflict with existing zoning for agricultural use, ❑ ❑ ❑ or a Williamson Act contract? c) Involve other changes in the existing environment which, due to their location or ❑ ❑ ❑ ED nature, could result in conversion of Farmland, to non-agricultural use? 2.1 Significance Criteria The proposed project would result in significant adverse agricultural resource impacts if the following occurs: San Juan Capistrano Ortega Highway Pipeline Pmlept S ESA / 2072n Initial Study I Mitigated Negative Dedii abon December 2007 Checklist • Loss or elimination of "prime" agricultural lands as designated by the State of California and/or County of Orange if such designated soils are capable of sustained, viable agricultural production. 2.2 Analysis Would the project. a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? Project Impact — No Impact The proposed pipeline would be installed within the highway right-of-way. No conversion of farmland is required. Therefore, impacts to Prime Farmland, Unique Farmland, or Farmland of Statewide Importance would not occur. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? Project Impact — No Impact The proposed project site crosses areas that are designated as Very Low Density Residential (0-1.0 du/acre)., Open Space Recreation, and the Residential/Agricultural District (San Juan Capistrano), and Suburban Residential, Open Space, and Urban Activity Center (County of Orange) by the applicable General Plans (City of San Juan Capistrano, 1999; County of Orange, 2005). While the project area does cross through a Residential/Agricultural zoned area, no part of the project crosses land designated as prime, unique or important farmland. Furthermore, the project would be located within the highway right-of-way and would not conflict with any existing agricultural zoning or a Williamson Act contract, and would not convert any farmland to non-agricultural use. e) Involve other changes in the existing environment, which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use? Project Impact—No Impact The proposed project would be located within the existing highway right-of-way. Therefore, the project would not result in conversion of farmland to non-agricultural uses.

San Juan Capistrano Ortega HigMxay Pipeline Project 10 ESA/20]2]3 Initial Study I Mitigated Negative Declaration D arnbar2007 0 Project Impact — Less than Significant The proposed project is located within the jurisdiction of the South Coast Air Quality Management District (SCAQMD) the regional agency empowered to regulate air pollutant emissions from stationary sources for all or portions of Los Angeles, Orange, Riverside and San Bernardino Counties. SCAQMD regulates air quality through its permit authority over most types of stationary emission sources and through its planning and review process. SCAQMD has prepared a revision to its Air Quality Management Plan (AQMP) in conjunction with the California Air Resources Board (CARB), the Southern California Association of Governments (SCAG) and the U.S. Environmental Protection Agency (U.S. EPA). The Final 2007 AQMP was adopted on June 1, 2007. The proposed project is consistent with the Orange County General Plan and the City of San Juan Capistrano General Plan and the AQMP. The project would not result in point -source emissions and does not include land use changes that would conflict with long-range air quality projections. The project would not conflict with or obstruct implementation of the Air Quality Management Plan. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Project Impact — Less than Significant Operational activity for the proposed project would be passive and include the conveyance of potable water through underground pipes. Potential long-term emission sources include emissions associated with maintenance/repair trips. The number of workers required for maintenance and operational activities would not result in a significant increase in traffic in the project area. Therefore, the effect of project -related traffic on local carbon monoxide concentrations along roadways and at intersections would also be negligible. Construction emissions would be the most substantial source of air quality emissions from the proposed project. Construction Emissions Construction due to the pipeline installation would generate emissions from excavation and soil fill/compaction activities, soils hauling, and worker commuter miles. The emissions would be small compared to those generated by the road widening project. Estimates of mass daily emissions during pipeline installation were compiled using URBEMIS 2002, which is an emissions estimation/evaluation model developed by the California Air Resource Board (CARB) that is based, in part, on SCAQMD CEQA Air Quality Handbook guidelines and methodologies. The URBEMIS 2002 output sheets provided in Appendix A. Calculations assume that construction of the pipeline would require approximately three months to perform. The total construction phase is assumed to require the following types of construction equipment: two dump -trucks, two excavators, one forklift, one grader, one backhoe, and one water truck. Calculated unmitigated emissions rates are presented in Table 1. As shown, construction -related daily emissions for the proposed project would not exceed SCAQMD significance thresholds.

SOURCE: ESA 2007. In addition to regulated air pollutants provided in Table 1, the proposed project would result in emissions of the greenhouse gas carbon dioxide (CO2) as a byproduct of combustion of gasoline and diesel fuel in construction equipment and construction worker commute trips, and from vehicle trips related to maintenance. As previously stated, the significance of the proposed project's CO2 emissions cannot be determined without substantial speculation. As there are no criteria at this time to evaluate the significance of the GHG emissions, no conclusion can be reached regarding this potential impact. In accordance with Section 15145 of the CEQA Guidelines, any potential impact regarding GHG emissions is too speculative for evaluation and no further discussion of this potential impact is required. c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region drops to a non -attainment status under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? Project Impact — Less than Significant with Mitigation Incorporated Please see sections 3.2 (a) and (b) above. Despite the success of regional air quality programs in improving the South Coast Basin's air quality, the air basin still exceeds health -based standards for ozone and particulate matter less than ten microns in size (PMIo)• Section 181(a)(1) of the Clean Air Act classifies the Basin as an extreme non -attainment area for ozone, and states that the Basin must achieve the federal ozone standard by June, 2021 (South Coast Air Quality Management Plan, 2007 Draft) (SCAQMP, 2007). The proposed project would not result in significant air quality impacts because it is limited to the underground installation of San Juan Gapistrano Ortega Highway Pipeline Project 12 ESA/207273 Initial Study I Mitigated Nei Declaration December 2037 0 0 Checklist approximately 5,287 linear feet of pipeline. However, project construction would require trenching activities that have the potential to contribute to cumulative airborne particles to the air basin. With implementation of Mitigation Measure AQ -1, these cumulative impacts would be reduced to less than significant. d) Expose sensitive receptors to substantial pollutant concentrations? Project Impact— Less than Significant Please see sections 3.2 (a), (b) and (c) above. While there are homes in the project area, the site is also a mixed use area defined partly as rural residential, suburban residential, open space and urban activity center. The "urban activity center" use is a future planned use within the County of Orange and not within the City of San Juan Capistrano. The area has a low residential population density. The nearest residences are located approximately 50 feet from the proposed pipeline. Construction would occur during planned Caltrans construction activity and would not add considerably to the duration of construction in front of individual properties. Due to the short- term nature of the project, impacts would be considered less than significant. There are no other sensitive receptors in the immediate project vicinity such as hospitals, care facilities, or schools. e) Create objectionable odors affecting a substantial number ofpeople? Project Impact — Less than Significant Project -related construction activities could result in short-term diesel emissions and associated objectionable odors. However, due to the small project size and its short-term nature, odor impacts would be less than significant. 3.3 Mitigation Measures AQ -1 Implement the following to minimize air emissions: • Water sufficiently to reduce off-site transport of fugitive dust from all unpaved staging areas and unpaved road surfaces. • Cover all trucks hauling soil, sand, and other loose materials. • All paved access roads, parking areas, and staging areas shall be swept as needed, and daily when soils, sand, and other loose materials are being hauled on or off the site, using SCAQMD Rule 1186 certified water sweepers or recommended water sweepers using reclaimed water. • All construction equipment shall be properly tuned and maintained in accordance with manufacturer's specifications. Adherence to SCAQMD Rules 431.1 and 431.2, which require the use of low sulfur fuel for stationary construction equipment.

Project Impact— Less than Significant with Mitigation Incorporated The San Juan Capistrano Ortega Highway Pipeline Project would be implemented in conjunction with, and subject to, the Caltrans Ortega Highway Widening Project. The installation of the pipeline would not require additional clearing of vegetation beyond the activities required for the roadway widening project. Conducting this project during the Caltrans construction provides an efficient means of completing the project without additional impacts to environmental resources including biological resources. Any biological resource impact resulting from the Caltrans Ortega Highway Widening Project would be mitigated by Caltrans in coordination with the City of San Juan Capistrano. The proposed project is located along a one -mile stretch of the Ortega Highway in southern California approximately four miles inland from the Pacific Ocean. The project area crosses from the eastern edge of the city of San Juan Capistrano into unincorporated Orange County. This section of the Ortega Highway lies within the Southern Subregion of the County of Orange Natural Community Conservation Plan and Habitat Conservation Plan (NCCP/HCP) The city is not a signatory to the Implementation Agreement for the Southern Sub -region NCCP. The City of San Juan Capistrano separately and in conjunction with Caltrans must comply with the requirements of the Clean Water Act (CWA), the California Clean Water Act (Porter -Cologne Water Quality Control Act), the San Diego Regional Water Quality Control Board (RWQCB), the Rivers and Harbors Act, the Streambed Alteration Agreement requirements under California Fish and Game Code Section 1601, the Federal Endangered Species Act (FESA), the Federal Migratory Bird Treaty Act (FMBTA), the California Endangered Species Act (CESA), the California Environmental Quality Act (CEQA), and the Native Plant Protection Act (NPPA). In addition, the proposed project falls under the jurisdiction of the City of San Juan Capistrano Tree Removal Ordinance. A variety of biological resources exist along the Ortega Highway corridor. Important vegetation communities include coastal sage scrub, non-native annual grasslands, urban/developed, freshwater seeps, and southern Sycamore Alder riparian habitat. Most of San Juan Creek upstream from the 1-5 freeway bridge is in its natural condition, with earthen banks and riparian vegetation. CDFG (2006) reports 48 special -status animals within the general vicinity of the project area. Special -status wildlife species recently reported or identified in the immediate project area include the coastal California gnatcatcher, least Bell's vireo, and yellow -breasted chat. The City of San Juan Capistrano's General Plan and Domestic/Recycled Water Master Plan identify ban Juan Capistrano Ortega Highway Pipeline Project t$ ESA/2072n Initial Study / Mibgated Negative Declaration December 2007 • 0 several species as occurring or likely to occur within City limits, including the arroyo toad, two - striped garter snake, southwestern pond turtle, arroyo chub, least Bell's vireo, coastal California gnatcatcher, and the coastal cactus wren (San Juan Capistrano, 1999; Domestic/Recycled Water Master Plan, 2007). The arroyo toad, southwestern pond turtle, two -striped garter snake, arroyo chub and least Bell's vireo are likely to occur along the City's creeks and streambeds, while the California gnatcatcher and coastal cactus wren are likely to occur in coastal sage scrub habitats. Other protected species in the project area include American badger, mountain lion, and mule deer. These species are generally found in grasslands, woodlands, open scrub, and mountain meadow habitats (San Juan Capistrano, 1999). There are 40 special -status plants recorded within the vicinity of the proposed project. Of these, the thread -leaved brodiaea, intermediate mariposa lily, coulter's saltbush and many -stemmed dudleya have a high potential of occurring in the coastal sage scrub areas of the project area. No construction would occur within open space areas, riparian areas or sage scrub. The entire construction activity would be conducted within the road widening construction zone cleared by Caltrans. Installation of the pipeline, equipment access and staging would not result in the direct or indirect mortality of special -status species. Tree removal would not occur, however, indirect disturbance resulting from construction activities could cause nest abandonment and death of young or loss of reproductive potential at active nests located near the pipeline route. Implementation of Mitigation Measure BIO -1 during construction adjacent to habitat for nesting raptors and other special -status nesting birds would reduce impacts to less than significant. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or US Fish and Wildlife Service? Project Impact — No Impact The proposed project requires one crossing of San Juan Creek. Construction activities would not result in the removal or disturbance of riparian habitat. The pipeline would be attached to the bridge over -crossing the creek. All construction activities would be confined to areas previously cleared and contoured by Caltrans. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Project Impact— No Impact The proposed project would not require a Section 404 permit from the USACE or a streambed alteration agreement with CDFG as the proposed pipeline project would not involve construction activities on wetlands as defined by section 404 of the Clean Water Act. Nonetheless, the City is required to comply with any conditions of the Section 404 and 401 permits and streambed alteration agreements obtained by Caltrans for their road widening project.

Project Impact — Less than Significant The proposed pipeline would be constructed within an existing roadway. Common wildlife adjacent to the roadways could be subjected to noise and other human disturbances. However, activities related to the project are temporary. Higher -than -normal disturbance levels would only occur in any one place for a relatively short period of time. Once constructed the underground pipeline would not obstruct wildlife movement. Therefore, the proposed project would result in a less -than -significant impact on common wildlife species. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Project Impact—No Impact Tree removal would not occur as a result of the project. The project would not conflict with local tree ordinances. P Conflict with the provision of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? Project Impact— No Impact The proposed project is located within the Southern Subregion of the County of Orange Natural Community Conservation Plan and Habitat Conservation Plan (NCCPiHCP). However, the proposed pipeline project would not impact coastal sage scrub habitat, San Juan Creek riparian habitat, nesting habitat for special -status raptors and other bird species, or other candidate, sensitive and special status species. The proposed project would not conflict with the provisions of the NCCP/HCP. 4.3 Mitigation Measures 13I0-1 The following mitigation measures would reduce potential impacts to biological resources. • Construction equipment shall avoid entering the creek banks and drainage area. • The City shall coordinate with Caltrans to identify and comply with construction restrictions during bird nesting season. • The City shall ensure that preconstruction bird surveys are conducted within 14 days prior to the start of construction activities during the nesting season (February 1 to August 31). If active nests are found during preconstruction surveys, the City shall comply with Caltrans' mitigation requirements for providing adequate non- disturbance buffer around active raptor nests and other nesting birds until it is San Juan Capistrano Dnega Highway Fpeline Pmlect 17 ESA / 201273 Initial Study/ Mitigated Negative Declaration December 2001 0 E determined that all young have fledged. The size of individual buffers can be adjusted based on an evaluation of the site by a qualified biologist. Site evaluations and buffer adjustments would be done in consultation with the local California Department of Fish and Game representative. If preconstruction surveys indicate that nests are inactive or potential habitat is unoccupied during the construction period, no further mitigation is required.

Project Impact — Less than Significant with Mitigation Incorporated According to the San Juan Capistrano General Plan (San Juan Capistrano, 1999), and the County of Orange General Plan (County of Orange, 2005), the project area has a long history of human habitation and use. Another recent study indicates that more than 70 prehistoric and historical cultural resources are located in San Juan Capistrano, but none appear to be in the immediate San Juan Capistrano Ortega Rghway Pipeline Project 18 ESA/20]2]3 Initial Study Mitigate! Negative Declaration December 2007 0 0 vicinity of the project area (Cultural Resources Inventory for the proposed Non- Domestic/Recycled Water Master Plan Update, City of San Juan Capistrano, Orange County, California, March 2007). It is possible that excavations for the pipeline could unearth historic or paleontologic artifacts. The number and density of historic resources in the area suggest that the project area should be considered to be part of an archaeological and historical district. The implementation of Mitigation Measure CR -1 is recommended to minimize impacts to cultural resources. If these measures are followed, the extent of project impacts to cultural resources will be less than significant. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? Project Impact — Less than Significant with Mitigation Incorporated According to the San Juan Capistrano General Plan (City of San Juan Capistrano, 1999), the San Juan Creek has been identified as an area of archaeological sensitivity. The proposed pipeline would be installed above the creek flood plain and would cross the creek along the existing Ortega Highway right-of-way. As such, most archaeological resources would have been recovered or destroyed during prior construction of the roadway. However, implementation of Mitigation Measure CR -1 would reduce the potential for encountering and disturbing known or unknown archaeological resources to less than significant. e) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Project Impact— Less than Significant with Mitigation Incorporated According to the San Juan Capistrano General Plan (City of San Juan Capistrano, 1999), the San Juan Creek has been identified as an area of archaeological sensitivity. The Orange County General Plan (County of Orange, 2005) General Areas of Paleontological Significance Map (Figure VI -9) the project area is within a sensitive area. The proposed pipeline would be installed above the creek flood plain and crossing the creek along the existing Ortega Highway right-of- way. Construction activities have the potential to expose buried paleontological resources. Implementation of Mitigation Measure CR -1 would reduce the impact to less than significant. d) Disturb any human remains, including those interred outside offormal cemeteries? Project Impact— Less than Significant with Mitigation Incorporated The proposed project would be located within existing roadways. No human remains are known to exist within the project site. However, construction activities have the potential to expose unidentified buried human remains. Implementation of Mitigation Measure CR -1 would reduce impacts to a less -than -significant level. San Juan Capistrano Ortega W.gbway Rpaline Project 19 ESA I20)2]3 Initial Study I MipgateE Negarbye Declaration December 2007 0 0 Checklist 5.3 Mitigation Measures CR -1 The following mitigation measures will be utilized to avoid negative impacts to cultural resources: The contract specifications shall require the City's contractor to retain the services of a RPA (Register of Professional Archeologists) -certified archeologist who will monitor all grading and excavation for potential impacts on cultural resources including archeological, paleontological, and historic resources. The contractor shall provide an executed contract for services with an RPA -certified archeologist including a scope -of -work which provides for comprehensive monitoring; a contingency for assessment, recovery, and/or evaluation; and the preparation of a technical memoranda or report. If historic and/or cultural resources are encountered during grading and/or building activities, the monitoring RPA archeologist may cease any grading and/or building construction activities, subject to confirmation by the City's Environmental Administrator (EA), to allow for preliminary assessment, evaluation of any cultural resources, and/or recovery. The archeological monitor or Environmental Administrator (EA) may allow grading activity to proceed at other locations on the project site which would not interfere with the assessment of uncovered cultural resources. Prior to completion of the project, the contractor shall assure that the archeological monitor submits a technical memorandum or cultural resources report which details archeological monitoring efforts, findings, analysis, and conclusions consistent with City Council Policy #601 and subject to review and approval of the Planning Director. If human remains are encountered, the City shall halt work in the vicinity of the find and contact the county coroner in accordance with Public Resources Code Section 5097.98 and Health and Safety Code Section 7050.5. If the coroner determines the remains are Native American, the coroner shall contact the Native American Heritage Commission (NAHC). As provided in Public Resources Code Section 5097.98, the NAHC shall identify the person or persons believed to be most likely descended from the deceased Native American.

Adverse soil conditions such as compressible, expansive, or corrosive soils present a damage hazard to occupied structures or infrastructure facilities. 6.2 Analysis Would the project: Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: a) i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on San Juan Capistrano Ortega Highway pipeline Project 21 ESA/20]2]3 Initial Study / Iddigated Negative Declam5on December 2007 0 0 other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. Project Impact — Less than Significant The proposed project is located in a seismically active area. However, no known active seismic faults traverse San Juan Capistrano or the project area. Consequently, the potential for ground rupture at the project area is low. The project does not occur within Alquist-Priolo Earthquake Fault Zone. Additionally, the pipeline would be designed in accordance with Uniform Building Code requirements and current seismic design standards to minimize seismic impacts. a) iL Strong seismic ground shaking? Project Impact— Less than Significant The project area is located within 50 miles of several known potential sources of strong seismic shaking, including the offshore segment of the Newport -Inglewood fault system located approximately six miles west of San Juan Capistrano, and the San Andreas fault system located approximately 50 miles east of the City. The Newport -Inglewood fault is considered an active fault requiring that special near -source factors be incorporated into buildings developed within 10 kilometers (6.2 miles) of the fault. The Uniform Building Code requires that most of the southwestern portion of the City incorporate near -source factors into the design of new buildings. Other faults located within 50 miles of the City include the offshore Palos Verdes fault, the Elsinore fault, the Whittier fault and the San Jacinto fault. A major earthquake associated with any of these faults could result in moderate to severe groundshaking in the project area. Damage to buildings and infrastructure, including pipelines, could be expected as a result of groundshaking during a seismic event. The most severe earthquake -caused damage to the pipeline would include rupture and displacement of the line. Because of its location along the shoulder of an existing roadway which runs parallel to the San Juan Creek floodplain, and which lies at least 50 feet away from and below the nearest structure, any water released from the pipeline would flow downstream into drainage ditches, toward the creek, and away from any structures. The pipeline will have emergency shut-off valve capacity to prevent any major release of water. Asa result, damage caused by strong seismic ground shaking would be less than significant. a) HL Seismic -related ground failure, including liquefaction? Project Impact — Less than Significant Damage from earthquakes is most often the result of liquefaction of alluvial soils underlying large rigid structures. Liquefaction occurs primarily in areas of recently deposited sands and silts and in areas of high groundwater levels. Poorly consolidated sediment and high groundwater levels occur most frequently in creekbeds and floodplain. The potential for liquefaction is particularly high in the floodways located along San Juan Creek. The proposed project would be constructed simultaneously with the widening of an existing roadway, in the right-of-way of that roadway. The widening project would involve compaction of the right-of-way, which would reduce the San Juan Capistrano Ortega Highway Pipeline Project 22 ESA/207273 Initial Study I Mitigated Negative Declaration December 2007 0 • liquefaction capacity of the soils. In addition, because it is a narrow, linear and relatively light structure, the pipeline itself would not require significant load-bearing strength in its underlying soils. Again, the pipeline would be designed and built in accordance with the Uniform Building Code and current seismic design standards to reduce the risk of damage caused by liquefaction. Therefore, the risk of loss or adverse effect caused by seismic -related ground failure, including liquefaction, would be less than significant. a) iv. Landslides? Project Impact — No Impact Unstable slopes are located throughout San Juan Capistrano. The hillsides adjacent to the Ortega Highway in the project area include slope regions that have confirmed, known or highly suspected landslides. The abundant shales and siltstones underlying the hills of San Juan Capistrano are highly porous and do not hold together well when wet, which can lead to slope instability and landslides. Secondary factors contributing to slope instability and landslides include rainfall and earthquakes. Debris flows can occur rapidly and without warning during periods of exceptionally high rainfall. The proposed pipeline would be installed completely underground within an existing highway right-of-way. As such, the pipeline would have a low profile relative to the adjacent land areas. The occurrence of a landslide or debris flow along the pipeline route and over the top of the pipeline would be unlikely to impact its short-term operation or cause damage to the pipeline itself. Neither construction of the pipeline, nor its operation, is likely to increase the risk of debris flows along the pipeline corridor. Nor would landslides or debris flows be likely to impact the operation of the pipeline. b) Result in substantial soil erosion or the loss of topsoil? Project Impact — Less than Significant with Mitigation Incorporated Construction activities involving soil disturbance, such as excavation, stockpiling, and grading could result in increased erosion and sedimentation to surface waters. Substantial erosion is considered unlikely because of the relatively small scale of earthmoving activities necessary for project implementation. The City of San Juan Capistrano will comply with all Caltrans permits regarding the excavation and deposit of fill materials in riparian areas. In addition, all disturbed areas within the construction footprint will be re -vegetated following project completion. Compliance with Mitigation Measure WQ-1 will also address erosion issues. Therefore, impacts related to erosion or loss of topsoil would be less than significant. c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? Project Impact— No Impact The proposed project would be located in a seismically active area that has been identified as having a high potential for liquefaction and susceptibility to landslides. The project would consist of the installation of a 12 -inch potable water pipeline within an existing roadway right -of - San Juan Capistrano Oda, Highway Pipeline Project 23 ESA/2072)3 Initial Study I Wnt,atud Negative Declaration Dxcamber 2007 • way. The soil would be compacted during road concurrent widening construction project. There are no standing structures associated with the project. The pipeline would be designed and built in accordance with the Uniform Building Code and current seismic design standards to reduce the risk of damage that could result from construction in areas with potential for liquefaction and landslide. Because the pipeline would be buried below ground and would have a low topographic profile, and because the construction footprint would be relatively narrow, it would not increase the risk of landslide, lateral spreading, subsidence, liquefaction or collapse. d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? Project Impact — Less than Significant Expansive soils possess a shrink -swell characteristic I that can result in structural damage over a long period of time. Expansive soils are largely comprised of silicate clays, which expand in volume when water is absorbed and shrink when dried. The relatively significant amounts of clay present in the underlying bedrock of the Capistrano and Monterey formations in San Juan Capistrano pose an expansive soils hazard. Soils derived from these formations are considered moderately to highly expansive. When construction occurs over a medium of this consistency, the resulting shrink/swell characteristics will likely result in damage to the overlying structures. The pipeline design would comply with the Uniform Building Code and current standards for the use or avoidance of expansive soil materials. Therefore, impacts related to expansive soils would be considered less than significant. e) Have soils incapable of adequately supporting the use of septic systems or alternative waste water disposal systems where sewers are not available for the disposal of waste water? Project Impact — No impact No impact would occur because the project does not include septic tanks or alternative wastewater disposal systems.

Be located on a site that is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would create a significant hazard to the public of the environment. • Results in a safety hazard for people residing or working in the project area if located within two miles of a public airport or public use airport. San Juan DapisVano Ortega Highway Pipeline Pn,j 25 ESA/207273 Initial Study I Mibgate Negative DaclaraU. December 2007 0 0 Checklist 7.2 Analysis Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Project Impact — No Impact No hazardous materials would be routinely transported, used, or disposed of during the operation of the pipeline, as the pipeline would supply domestic drinking water. Therefore, no impact would result. b) Create a significant hazard to the public or the environment through reasonable foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Project Impact — Less than Significant Construction activities would involve the use of certain potentially hazardous materials such as fuels and hydraulic fluids. These materials would generally be used for construction equipment, and would be contained within vessels engineered for safe storage. Storage of large quantities of potentially hazardous materials at the construction site is not anticipated. Therefore, impacts are considered less than significant. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Project Impact — Less than Significant As discussed above, no hazardous materials would be routinely used during the operation of the pipeline. Moreover, no schools are located within one-quarter mile of the project site. Therefore, impacts are considered less than significant. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? Project Impact — No Impact No impact would occur because the proposed project site is not included in the list of hazardous materials sites, pursuant to Government Code Section 65962.5 (California Department of Toxic Substances Control, 2007). e) For a project located within 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 result in a safety hazard for people residing or working in the project area? San Juan Capisbano Ortega Highway Pipeline Project 26 ESA/20]2]3 Initial Study / Mg -Led HagaUve OeclaraUoa pecem6ar 2037 0 0 Project Impact — No Impact No impact would occur because the proposed project is not located within two miles of a public airport. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? Project Impact — No Impact There are no private airstrips within two miles of the project area. The project would not result in a safety hazard for people working in the project area because of its distance from any airport. g) impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Project Impact — No Impact Access to and from the Ortega Highway would be maintained during pipeline installation. The underground pipeline would not interfere with any emergency response plan or evacuation plan. During the construction of the roadway widening and pipeline installation there would be temporary traffic control features. However, theses features would not inhibit emergency responses or emergency evacuation. Therefore, the project would not interfere with an emergency response plan or evacuation plan and no impact would occur. h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? Project Impact — Less than Significant. The proposed project would be constructed within the Ortega Highway right-of-way and does not include any above ground structures other than minor pipeline appurtenances. As a result, the proposed project would not expose people or structures to a significant risk of loss, injury or death involving wildland fires. No impact would occur during pipeline operations. During construction, the storage of flammable materials and the operation of heavy machinery in areas adjacent to residential areas, or near wild scrub and grasslands could expose people or structures to an increased risk of wildland fire. However, the proposed project would occur entirely within Caltrans' construction zone during the road widening. The City would comply with Caltrans staging area restrictions. No vegetation would remain within the construction zone. The potential for starting wildfires would be less than significant.

Project Impact — Less than Significant with Mitigation Incorporated During the construction phase of the project, excavated soils could erode and be transported to down -gradient drainages. The proposed pipeline trench will be approximately 0.24 of an acre and San Juan Capistrano Onega Highway Pipeline Prnlect 28 ESA/207273 Initial Study/ Mitigated! Negative Declaration December 2007 0 0 would therefore not be subject to the State Water Resources Control Board construction storm water permit. However, the City would comply with Caltrans' Storm Water Pollution Prevention Plan (SWPPP) prepared to comply with the National Pollution Discharge Elimination System (NPDES). Mitigation Measure WQ-I requires the City to comply with the best management practices in Caltrans' SWPPP that apply to the construction methods used to install the pipeline. Implementation of the SWPPP would ensure a less than significant impact to water quality. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (eg., the production rate ofpre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted? Project Impact — Less than Significant The proposed pipeline installation project would not require the use of groundwater supplies that would deplete the aquifer. The pipeline would be installed within a pipeline improvement corridor and would not affect the groundwater recharge since it would be placed beneath a surface that would paved by the Caltrans project. Soil compaction above the pipeline would be suitable for Caltrans roadway construction. Impacts would be less than significant. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner that would result in substantial erosion or siltation on- or off-site? Project Impact — Less than Significant The proposed project would be located within an existing highway right-of-way. The proposed pipeline would be located below ground and would not include any surface structures other than minor pipeline appurtenances. No stream alterations would occur from the proposed project. The completed project would not substantially impact or degrade the drainage pattern of the site, and therefore would not result in substantial erosion or siltation on- or off-site, nor will the pipeline have any effect on the drainage pattern, or surface run off characteristics. Those will be dictated by the roadway. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site? Project Impact — Less than Significant The proposed project would be located within an existing highway right-of-way. The proposed pipeline would be located below ground and would not include any surface structures other than minor pipeline appurtenances. No stream alterations would occur from the proposed project. The completed project would not substantially impact or degrade the drainage pattern of the site, and therefore would not result in substantial flooding on- or off-site. e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources ofpolluted runoff? San Juan Capistrano Ortega Highway Pipeline Prolact 29 ESA 120]2]3 Initial Study 1 Mitigated Negative Declaration December 2007 Project Impact — No Impact Construction of the proposed pipeline project would not result in increased impervious surfaces as the project would be located underground with the existing highway right-of-way. The project would occur during the Caltrans highway widening project which would result in increased impervious surfaces. However, the widening project has been designed and engineered to accommodate increased runoff. Additionally, the Caltrans widening project would contribute sources of polluted runoff from the associated vehicular traffic. Increased runoff volume and pollution amounts from the Caltrans project have been adequately addressed in the design and environmental review for that separate project. The proposed underground pipeline project would not cause stormwater drainage systems to be exceeded or contribute additional sources of polluted runoff. fi Otherwise substantially degrade water quality? Project Impact — Less than Significant Substantial erosion and the production other constituents that impair water quality is considered unlikely because of the relatively small scale of earthmoving activities necessary for project implementation and the relatively small amount of equipment required to competed the project. Therefore, the proposed project would not substantially degrade water quality. Nonetheless, standard erosion control techniques would be implemented during project construction activities (see Mitigation Measure WQ-1). g) Place housing within a 100 year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? Project Impact — No Impact Although the pipeline itself will cross the 100 -year flood plain in some locations, the project does not propose housing or other structures within the 100 -year -flood boundary (County of Orange, 2005). Therefore, no impact would occur. h) Place within a 100 year flood hazard area structures that would impede or redirect flood flows? Project Impact — No Impact The proposed pipelines would be underground and would not impede or redirect flood flows. Therefore, the project would not result in flood -related impacts. i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? Project Impact — No Impact The proposed project would distribute water throughout the City's service area and would not include the storage of water on-site. As a result, the project would not expose people or structures to a significant risk of loss, injury or death involving flooding from levee or dam failure. Therefore, no impacts would occur. San Juan Capistrano Ortega Highway Pipeline Project 30 ESA/207273 Initial Study I Mitigated Negatlye Declaration December 2007 0 0 j) Expose people or structures to inundation by seiche, tsunami, or mudillow? Project Impact— No Impact Construction of the proposed project will take place entirely in the highway right-of-way and will not impact or undercut the slope of the surrounding hills. Also, the creek crossing is above the surge tide of any possible inundation by seiche or tsunami. Therefore, the construction and operation of the pipeline will not increase or impact the natural risk of inundation by seiche, tsunami or mudflow at the project area, and no impacts are anticipated. &3 Hydrology and Water Quality Mitigation Measures WQ-1 The City shall require that contractors comply with the Best Management Practices (BMPs) for erosion and sedimentation control identified in Caltrans' SWPPP for the roadway project. 9.1 Significance Criteria The proposed project would result in significant adverse land use and planning impacts if any of the following occur: • An established community is physically divided. • The project conflicts with the County of Orange or City of San Juan Capistrano General Plan or zoning ordinance. • The project conflicts with the Southern Subregion Coastal Sage Scrub Natural Community Conservation Plan. • The project is incompatible with the adjacent land uses.

Negative Declaration December 2007 0 9.2 Analysis Would the project. a) Physically divide an established community? Project Impact — No Impact 0 The proposed project involves the construction of an underground water pipeline within a highway right-of-way. The pipeline would be entirely underground. Therefore, the proposed project would not divide an established community and no impact would occur. b) Conflict with any applicable land use plan, policy or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? Project Impact — No Impact The proposed project is subject to the Orange County General Plan (County of Orange, 2005), and the San Juan Capistrano General Plan (San Juan Capistrano, 1999). The project would occur within the right-of-way of an existing, paved road. All environmental effects would be avoided or mitigated according to the applicable land use policies, plans and regulations. As a result, the project would not conflict with any applicable land use plan, policy, or regulation and no impact would occur. Additionally, this project is consistent with the City's Water Master Plan. c) Conflict with any applicable habitat conservation plan or natural community conservation plan? Project Impact — No Impact The proposed project would be implemented in accordance with the Southern Subregion Coastal Sage Scrub Natural Community Conservation Plan (NCCP/HCP).

Project Impact — No Impact The proposed project is not located within any designated mineral resource zone where mineral deposits are likely to exist. The proposed project would be located along an existing roadway, and any unknown mineral resources would presumably have been found at the time of roadway construction. Therefore, no impacts to known mineral resources are anticipated. b) 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? Project Impact — No Impact The proposed project is not located within any designated mineral resource zone where mineral deposits are likely to exist.

Project Impact— Less than Significant with Mitigation Incorporated The regional noise environment in the community of San Juan Capistrano and unincorporated Orange County is relatively quiet, as the neighborhood designations range from open space to residential to commercial. Population density is low. Project construction would result in intermittent, elevated, temporary noise levels in and around the project sites. Construction noise and vibration would result from operation of equipment and vehicles and would fluctuate depending on equipment type, duration of use, and distance between the noise source and receptor. Construction of the proposed project would temporarily increase ambient noise and vibration levels at nearby sensitive receptors (residences). The nearest residences are located approximately 50 feet from the proposed pipeline. Implementation of Mitigation Measures NOI-1 and NOI-2, in compliance with the City of San Juan Capistrano noise regulations for construction, would reduce noise and vibration impacts to less -than -significant levels. b) Exposure ofpersons to a generation of excessive groundborne vibration orgroundborne noise levels?

Project Impact — Less than Significant The proposed project would construct a potable water main that would increase the capacity of the existing water system. The project would increase the reliability and quality of service within the existing water distribution system to adequately serve existing users, and to meet increasing fire safety demands. Because the project is limited to the provision of water supply infrastructure, as opposed to housing or commercial development that would directly affect the number of residents or employees in the region, the proposed project would not directly contribute to the creation of additional housing orjobs within the City of San Juan Capistrano or the County of Orange. Furthermore, the project would be consistent with the San Juan San Juan Capistrano Ortega Highway Pipeline Project 36 ESA I M7275 Initial study IM Wtetl Negative Declamfim December 2007 E Capistrano General Plan, which is consistent with the Orange County General Plan; both plans anticipate growth along the Ortega Highway corridor. As a result, the project would facilitate planned growth in the area not induce population growth.

Project Impact — Less than Significant San Juan Capistrano Ortega Highway Rpoline Project 40 ESA/20]2]3 Initial Study / MitlgateC Negative Ded.ah.n December 2007 The pipeline would be installed along the roadway using standard open -cut trenching techniques. It is anticipated that the pipeline would be installed during the Caltrans widening of the highway. The traffic generated by the pipeline installation activities would be minor compared to the overall impact of the road widening project. Furthermore, impacts would be relatively brief at any one location along the pipeline alignment. The City would be subject to traffic control plans prepared by Caltrans. Impacts to traffic would be less than significant. b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? Project Impact — Less than Significant Please see section 15.2 (a) above. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? Project Impact — No Impact There is no public or private airstrip in the vicinity of the project area. The proposed project would not result in the use of any construction equipment that could obstruct air traffic patterns, nor would there be any permanent above -ground structures, except for minor appurtenances, after project completion. Project implementation would have no impact on air traffic patterns. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Project Impact — No Impact The proposed project would not change the configuration (alignment) of area roadways, and would not introduce types of vehicles that are not already traveling on area roads. The project would not result in increased hazards to design features. e) Result in inadequate emergency access? Project Impact— Less than Significant The project would occur during Caltrans' road widening project. Installation of the pipeline would be a minor portion of the overall Caltrans project. The City would be subject to Caltrans emergency access plans. The project's impact would be less than significant. f) Result in inadequate parking capacity? Project Impact — Less than Significant Impact The project would create a temporary parking demand for construction workers and construction vehicles as the crew moves along the installation alignment. The project would not generate a substantial number of construction workers along the alignment; therefore, the number of parking spaces required would not be substantial and impacts would be considered less than significant. Operation of the proposed project would not result in parking demand except for limited San Juan Capistrano Ortega Highway Pipeline Project 41 ESA/20]2]3 Initial Study / Mitigated Negative Declaration December 207 E maintenance vehicles. Maintenance vehicle parking could be accommodated in the right -of —way shoulder. Impacts would be less than significant. g) Conflict with adopted policies, plans or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)? Project Impact — Less than Significant The community of San Juan Capistrano has an extensive network of bike and pedestrian trails. A Class 3 bike lane currently exists along the Ortega Highway and along Toyon Drive. In addition, Orange County has designated the Ortega Highway as a Class II Bikeway, which means that there is a designated bike lane along the shoulder of the road. Post -construction operation of the pipeline will not impact these alternative transportation routes. The City would be subject to traffic control plans prepared by Caltrans. Impacts to traffic would be less than significant. Less Than Significant Potentially with Less Than Significant Mitigation Significant Issues Impact Incorporation Impact No Impact XVI.

San Juan Capistrano Ortega Highway Pipeline Project 42 ESA/207273 Initial Study / Mitigated Negative Declaration December 2007 0 0 Checklist Explanations 16.1 Significance Criteria The proposed project would result in significant adverse utilities and service system impacts if any of the following occur: • The project -related demand caused an increase in wastewater treatment that reached or exceeded the current capacity of existing or planned treatment facilities or caused a reduction in the level of service, thereby requiring substantial expansion of existing facilities or the construction of new facilities. • The proposed project's use of water resources will substantially and adversely deplete existing sources of domestic water. • The proposed project will require the construction of new water facilities beyond those already planned and the cost of which would not be borne by the applicant. • The project will generate solid waste that exceeds the capacity of the landfill to accept and dispose of the waste. 16.2 Analysis Would the project. a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? Project Impact — No Impact The proposed project is limited to the construction and operation of a potable water main pipeline. The proposed project would not involve any wastewater treatment. Therefore, no impact would occur. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Project Impact — No Impact The project proposes construction of a potable water main pipeline to extend water service to existing users, and to meet increasing fire safety demands, within the service area. As a result, the project would not require the construction of a new water or wastewater treatment facility. Therefore, no impacts would occur. c) Require or result in the construction of new stormwater drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Project Impact — No Impact The project would not require the construction of new stormwater drainage facilities or expansion of existing facilities, no impacts would occur.

Project Impact — No Impact The proposed project is consistent with the San Juan Capistrano General Plan, (San Juan Capistrano, 1999), the Orange County General Plan (County of Orange, 2005) and the San Juan Capistrano Water Master Plan. The project would enhance service flexibility of the system. No adverse impacts to the water supply would occur. e) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? Project Impact — No Impact Please see section 16.2 (d) above. The proposed project will facilitate the transfer of water from one zone to another. The project would be consistent with the growth anticipated in the San Juan Capistrano Water Master Plan, General Plan and the County of Orange General Plan. As such, the project would not exceed existing wastewater treatment capacity. No impact would occur. Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? Project Impact— Gess than Significant Impact Solid waste generation would be limited to construction activities, and would not affect available solid waste disposal capacity in the region. Therefore, impacts would be considered less than significant. g) Comply with federal, state, and local statutes and regulations related to solid waste? Project Impact— No Impact The contractor would be required to comply with all pertinent regulations regarding the disposal of solid waste generated by construction activities. Therefore, no impacts would occur. XVII.

MANDATORY FINDINGS OF SIGNIFICANCE Does the project. a) Have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop 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? Project Impact— Less than Significant Based on the analysis above, the proposed underground municipal pipeline project with mitigation incorporated (as specified where appropriate above) will not degrade the quality of the environment or substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife species population to drop 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 species, or eliminate important examples of the major periods of California history or prehistory. Potential impacts associated with the implementation of the pipeline project would be less than significant. b) Have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of project are considerable when viewed in connection with the effects ofpast projects, the effects of other current projects, and the effects of probably future projects)? Project Impact — Less than Significant Impact The proposed project's environmental impacts would be limited to short-term construction impacts which would be reduced to less -than -significant levels with implementation of mitigation measures identified in this document. Therefore, the project would not contribute to cumulatively considerable impacts.
