Miller NOES: Barrett ABSENT: None ABSTAIN: None ATTEST: i`jj��'City Clerk ayor Resolution No. 2014-126 N.C.S. Page 3 EXHIBIT A FINDINGS CONCERNING SIGNIFICANT IMPACTS AND MITIGATION MEASURES Pursuant to Public Resources Code section 21081 and CEQA Guidelines section 15091, the City Council hereby makes the following findings with respect to the potential for significant environmental impacts of the Riverfront Mixed -Use Development (File No. 11 -TSM -0130) ("Project") and means for mitigating those impacts. For the purpose of these findings, the term FIR means the Draft and Final EIR documents collectively, unless otherwise specifies. These findings do not attempt to describe the full analysis of each environment impact contained in the EIR. Instead the findings provide a summary description of each impact, identify the applicable mitigation measures set forth in the EIR and adopted by the City, and state findings on the significance of each impact after imposition of the adopted mitigation measures. A full explanation of these environmental findings and conclusions is in the EIR, and these findings hereby incorporate by reference the discussion and analysis in those documents supporting the EIR's determinations regarding mitigation measures and the Project's impacts and mitigation measures designed to address those impacts. The facts supporting these findings are found in the record as a whole for the project. In malting these findings, the City ratifies, adopts, and incorporates into these findings the analysis and explanation in the EIR, and ratifies, adopts, and incorporates into these findings the determination and conclusions of the EIR relating to environmental impacts and mitigation measures, except to the extent that any such determinations and conclusions are specifically and expressly modified by these findings. Many of the impacts and mitigation measures in the following findings are summarized rather then set forth in full. The text of the Draft and Final EIRs should be consulted for a complete description of the impacts and mitigations. Impact 4.1-1 — Criteria Pollutant Emissions: The project would result in emissions during construction and from vehicles once development is complete, which would not be considered significant except for generation of fugitive dust during construction. This is considered a potentially significant impact. AIR -1: Require implementation of Basic Control Measures during construction. AIR -2: Include the listed construction specifications measures (GP Policy 4-P-16) such as maintaining equipment, using alternative fuels, equip construction equipment with Best Available Control Technology, and require use of CARB's most recent certification standards. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: Implementation of mitigation measures will reduce fugitive dust emissions from grading as recommended by BAAQMD. Exhaust emissions from construction equipment and trucks for criteria pollutants would be below the BAAQMD thresholds for criteria Resolution No. 2014-126 N.C.S. Page 4 pollutants as described in the EIR, and would be further minimized through implementation of measures during construction activities. Impact 4.1-2b — Expose Sensitive Receptors to Pollutants During Construction: Sensitive onsite receptors could be temporarily exposed to substantial concentrations of pollutants during construction due to diesel equipment exhaust. AIR -3: Require that construction activities achieve an additional 60 percent reduction in exhaust particulate matter emissions, compared to similar equipment based on CARB statewide average emissions when building construction activities occur within 200 feet of any residential use. Methods to achieve this objective includes the use of Tier 2 standard equipment, alternatively fueled equipment (LPG fuel), and/or prohibit the use of diesel powered generators for more than two days when line power is available. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: Implementation of mitigations will reduce exhaust emissions within 200 feet of residential uses to less than applicable exposure thresholds. The mitigations employ a combination of techniques to reduce exposure concentrations including that construction equipment demonstrate optimal function and performance, use alternative fuels, and be equipped with Control Technology such as oxidation catalysts or particulate filters. Exhaust emissions from construction equipment and trucks would be reduced by 64% as a result of this measure. Therefore, after applying this measure, the impact would be less than significant. Impact 4.1-3 — Objectionable Odors: Future construction and development of the site, resulting from the proposed project, will not result in the generation of objectionable odors in substantial concentrations. However, occupancy of the project site has the potential to expose new residents to objectionable odors. AIR -4: Provide reimbursement to the City for the design and construction of the Primary Influent Pump Station mechanical odor control unit. The odor control unit shall meet current design criteria and be equivalent to the units installed at recent pump station upgrades within the City. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: Implementation of a mechanical odor control unit to replace the existing soil bed filter would substantially reduce detectable odors. Therefore, after applying this measure, the impact would be less than significant. Impact 4.2-1 - IPetlands: The proposed project would result in fill of 0.24 acres of onsite wetlands, most of which are jurisdictional wetlands. Although the fill will not result in significant impacts to special status species or habitat value, due to the fact wetlands are considered sensitive habitats, this is a potentially significant impact. Resolution No. 2014-126 N.C.S. Page 5 BIO -1: To mitigate for the impacts to 0.24 acres of seasonal wetland habitat, the developer shall purchase credits from an approved mitigation bank at a ratio of one acre for every one acre impacted, or as otherwise directed by the regulatory agencies (U.S. Army Corps of Engineers). Prior to issuance of grading permit, proof of purchase of mitigation bank credit or verification of onsite wetland remediation to offset losses shall be submitted to the City and U.S. Army Corps of Engineers. 13I0-2: Develop final Riverfront Park design that avoids and protects wetlands. The design shall also investigate the feasibility of creating wetland habitat as part of the proposed Riverfront Park, which could serve to offset losses in lieu of purchasing credits (See BIO -1). Implement standard best management practices (BMP) to protect wetland areas during and after construction of the Riverfront Park to include, but not be limited to installation of protective stalling and silt fencing to prevent inadvertent intrusion by equipment during construction. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Those changes or alterations are within the responsibility and jurisdiction of the U.S. Army Corps of Engineers and have been, or can and should be, adopted by that agency as part of the requisite 404 Nationwide dredge and fill permit. Rationale for Finding: Implementation of mitigations will protect wetland habitat and/or offset any losses to wetland habitat through the procurement of mitigation bank credits. Therefore, after applying this measure, the impact would be less than significant. Impact 4.2-2 — Special Status Species: Site preparation could result in direct impacts to nesting bird species, if they are present, including potential special status bird species. 13I0-3: Conduct vegetation removal within areas to be developed between September 1 and January 30, outside of the general breeding bird season. If this is completed, no further mitigation is required. Otherwise, if vegetation removal or modification occurs between February 1 and June 15, require pre -construction nesting surveys within 14 days prior to such activities to determine the presence and location of nesting bird species. If vegetation removal or modification occurs between June 16 and August 31, pre -construction surveys shall be performed within 30 days prior to such activities. If active nests are present, establish temporary protective breeding season buffers to avoid direct or indirect mortality of these birds, nests or young. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: Implementation of mitigation will protect special status species by controlling the seasonal timing of vegetation removal or requiring nesting bird surveys if occurring within the breeding season. Therefore, after applying this measure, the impact would be less than significant. Resolution No. 2014-136 N.C.S. Page 6 Impact 4.3-1 - Discovery of Archaeological Resource: The project has the potential to disrupt previously undiscovered archeological resource. CUL -1: If during the course of ground disturbing activities, historic resource is encountered, all work within a 100 foot radius of the find shall be suspended for a time deemed sufficient for a qualified and city -approved cultural resource specialist to evaluate and determine significance of the discovered resource. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: Implementation of mitigation ensures that currently unknown archeological resources will not be inadvertently disturbed or destroyed as a result of construction activities. Through the requirement to suspend construction work within 100 feet of a find, the cultural significance of such a resource can be assessed and construction work can proceed as appropriate. Therefore, after applying this measure, the impact would be less than significant. Impact 4.3-2 — Disturb Human Remains: The project could disturb undiscovered human remains, including those interred outside of formal cemeteries. CUL -2: In the event that human remains are discovered, all work shall be suspended and the Sonoma County Coroner shall be contacted in accordance with provisions of the California Public Resources Code section 5097.98-99. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: Implementation of mitigation ensures that currently unknown human remains will not be inadvertently disturbed or destroyed through ground disturbance as a result of construction activities. Therefore, after applying this measure, the impact would be less than significant. Impact 4.4-1 — Exposure to Seismic Hazards: Future project structures, residents and occupants at the site would be subject to strong seismic shaking and liquefaction hazards. GEO-1: Require implementation of all recommendations as set forth in the geotechnical investigations and updates prepared for the subject property by Miller Pacific Engineering Group (dated March 2006, July 2009, August 2011, January 2013, December 2013). Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The Project is subject to the California Building Code (CBC) which recognizes the seismic risk of developing in this state and includes stringent design and Resolution No. 2014-126 N.C.S. Page 7 construction requirements and engineering applicable not only to future Project structures but also to grading, foundations, retaining walls and other structures. The Project prepared a preliminary Soils and Geotechnical investigation, which was peer reviewed as part of the EIR process. Compliance with the CBC regulatory scheme and implementation of the specific recommendations provided in aforementioned studies, will result in improvement designs that mitigate the identified geotechnical conditions. The Project will be subject to a process of increasingly detailed engineering review to ensure that ground shaking is addressed at each phase of the development process and that CBC requirements are satisfied and study recommendations are carried out. Therefore, after applying this measure, the impact would be less than significant. Impact 4.4-2 — Soil Seltlement: Future structures at the project site would be subject to soil settlement with potential damage to structures and utilities. GEO-2: Implement the recommendations of the project geotechnical investigations and updates prepared for the subject property by Miller Pacific Engineering Group (dated March 2006, July 2009, August 2011, January 2013, December 2013), except as modified based on site-specific refinements. Settlement mitigation measures shall include use of structural foundation systems (such as mat slabs or rigid interconnected grade beams) for residential structures, which can withstand the potential total and differential settlements in accordance with recommendations of the geotechnical investigations and deep foundations (driven piles or drilled piers) for heavier structures planned in the northern portion of the site. Ground improvement, such as with the use of Rammed Aggregate Piers (RAP), may also be appropriate at certain locations within the site. GEO-3: Prior to the issuance of grading permits and in accordance with City of Petaluma Improvement Plan submittal requirements and procedures, the developer shall submit construction plans along with Design Level Geotechnical analysis that specifically addresses the thicker fills up to ten feet in the area near the Future Caulfield Lane Bridge in the southern portion of the site. The Improvement Plans and design level geotechnical analysis shall be subject to third party peer review in order to verify that recommended measures to address differential settlement of bay mud associated with thicker fills up to ten feet near the Future Caulfield Lane Bridge are adequate to accommodate potential settlement. In event that peer review concludes that the recommended design measures will not sufficiently minimize the effects of differential settlement, the developer shall be required to implement one of the following standard construction techniques: 1) the use of lightweight fill material in place of heavier, existing soils on areas that require thicker fill, or 2) pre -load areas that require thicker fill and allow settlement to occur prior to construction. The developer shall be responsible for the cost of the peer review and the City's Public Works Department shall coordinate the scope of service and approve findings of the peer review prior to the issuance of grading permits. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The required design -level geotechnical report and preliminary Soils and Geotechnical Investigation, which was peer reviewed as part of the EIR process, will be reviewed along with the existing geotechnical studies to ensure that through compliance with Resolution No. 2014-126 N.C.S. Page 8 applicable soil settlement regulation in the CBC and the City's standard engineering practices and design criteria for soil stability will be implemented in project construction and improvement to ensure that proper soil engineering, foundation design and construction will be implemented to avoid hazards from soil instability. Therefore, after applying this measure, the impact would be less than significant. Impact 4.4-3 — Expansive Soils: Future structures at the project site would be subject to expansive soils with potential damage to structures and utilities. GEO-1: Require implementation of all recommendations as set forth in the geotechnical investigations and updates prepared for the subject property by Miller Pacific Engineering Group (dated March 2006, July 2009, August 2011, January 2013, December 2013). HYDRO -1: Prepare final drainage plan as part of the Subdivision Improvement Plans that provides calculations and documentation that the site storm drain system and discharge culverts have adequate capacity to serve the project and watershed area at full buildout. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The required design -level geotechnical report will build on the existing geotechnical studies to show how regulation in the CBC and the City's standard engineering practices and design criteria for soil stability will be implemented in project construction and improvement. The City will review the design level report and ensure compliance with applicable CBC regulation. The mitigation will ensure that proper soil engineering, foundation design, adequate site storm drain system capacity, and construction will be implemented to avoid hazards from expansive soils. Therefore, after applying this measure, the impact would be less than significant. Impact 4.4-4 — Erosion: Grading at the project site could result in inadvertent erosion or soil transport into the Petaluma River. HYDRO -2: In accordance with National Pollution Discharge Elimination System (NPDES) regulations, the developer shall prepare a Storm Water Pollution Prevention Plan (S WPPP) for grading and construction of subdivision improvements. HYDRO -3: The applicant shall prepare and implement an erosion control plan for the subdivision grading and each subsequent development phase site plan. HYDRO -4: The applicant shall prepare and implement an erosion control plan for construction of the trail and improvements for the offsite Riverfront Park. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: Implementation of mitigations would substantially reduce the potential Resolution No. 2014-126 N.C.S. Page 9 for erosion and sedimentation by ensuring that construction activities employ the most effective erosion control practices such as site watering, stabilizing soils when inactive, and avoiding active construction during periods of heavy precipitation. Therefore, after applying this measure, the impact would be less than significant. Impact 4.5-2 — Exposure to Soil -Mater Contamination: The potential reuse of onsite stockpiled soils or discovery of unknown hazardous materials during construction could pose a hazard to workers during construction. I4AZMAT-1: Require that the quality of the stockpiled soils be reaffirmed / tested prior to use for onsite fill, which shall be done following the Clean Imported Fill Material Information Advisory prepared by the DTSC (DTSC 2001) in accordance with the recommendation set forth in the 2013 his Environmental Phase I Environmental Site Assessment. HAZMAT-2: Prepare and implement a Risk Management Plan (RMP) that provides the procedures to properly manage site groundwater that may be encountered during construction activities. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The mitigation recognizes that unknown hazardous materials may be discovered during construction and ensures that an effective construction worker safety program is established, so as to limit exposure of workers to hazardous materials. Therefore, after applying this measure, the impact would be less than significant. Impact 4.6-1 — Stornnvater Drainage: Buildout of the project site would result in a significant increase in stormwater runoff that would ultimately discharge into the Petaluma River, and which would result in potentially significant impacts if storm drains are not properly sized. HYDRO -1: Prepare final drainage plan as part of the Subdivision Improvement Plans that provides calculations and documentation that the site storm drain system and discharge culverts have adequate capacity to serve the project and watershed area at full buildout. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The mitigation recognizes that adequately sized infrastructure is necessary in order to ensure that stormwater runoff capacity is provided as part of the Improvement Plans. The preliminary plan shows that sufficiently sized pipes are feasible and mitigation requires that final drainage plans provide precise calculation and documentation that discharge facilities are properly sized. Therefore, after applying this measure, the impact would be less than significant. Impact 4.6-2 — lVater Oualiq, & Stormtivater Discharge: Grading activities and future runoff from the developed project site could result in non -point and point source pollution into the Resolution No. 2014-126 N.C.S. Page 10 Petaluma River, if not properly controlled. This is a potentially significant impact since the river is listed as impaired for nutrients, pathogens and sediment. HYDRO -2: In accordance with National Pollution Discharge Elimination System (NPDES) regulations, the developer shall prepare a Storm Water Pollution Prevention Plan (SWPPP) for grading and construction of subdivision improvements. HYDRO -3: The applicant shall prepare and implement an erosion control plan for the subdivision grading and each subsequent development phase site plan. HYDRO -4: The applicant shall prepare and implement an erosion control plan for construction of the trail and improvements for the offsite Riverfront Park. HYDRO -5: Subsequent development phases over one acre in size shall submit plans and detailed calculations to show that requirements for post -construction runoff treatment have been met in accordance with the City's stormwater management regulations. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The mitigation recognizes that the project is subject to NPDES and other water quality control regulations that will protect water quality. Implementation of mitigations would substantially reduce the potential for water quality degradation through accidental release of potentially harmful or hazardous materials and sediment by minimizing the potential for such materials and sediment to enter the Petaluma River. Therefore, after applying this measure, the impact would be less than significant. Impact 4.7-1 — Elevated Noise Exposure: The project could expose people to noise levels that exceed the Petaluma General Plan 2025 Land Use -Noise Compatibility Standards and City regulations. NOISEA: Pursuant to General Plan Policy 10 -P -3C and the CPSP EIR Mitigation Measure 10-1, a detailed acoustical report shall be prepared by a qualified acoustical specialist as part of the design phase to determine the noise control treatments for the residential buildings, offices and the hotel to meet local and state standards. Noise attenuation measures shall include as appropriate thicker walls, stucco siding, sound insulating windows and/or doors, building and bedroom orientation, and other measures pursuant to the detailed acoustical report. To achieve the noise reduction requirements, some form of forced air mechanical ventilation, satisfactory to the local building official, would be required in all residential units and the hotel. Special sound rated building elements such as windows and doors may also be necessary to reduce the intrusiveness of the train noise given that typical noise levels could reach 95 dBA Lmax outside the nearest townhomes if Quiet Zone status is not approved. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Resolution No. 2014-126 N.C.S. Page 1 I Rationale for Finding: The mitigation ensures that noise attenuation measures are further refined through the design level acoustical report. Implementation will be realized through various attenuation techniques that consider the entire building envelope to achieve City prescribed noise standards. Noise attenuation will minimize noise intrusion and substantially lessen interior noise levels. Therefore, after applying this measure, the impact would be less than significant. Impact 4.7-5 — Temporaiy Increase in Noise: Noise levels generated during construction activities would result in a temporary increase in ambient noise levels for an approximately six- year period during buildout of future development phases. NOISE -2: In accordance with Mitigation Measure 10-2 of the Central Petaluma Specific Plan, require implementation of the following measures during all phases of project construction: • Construction Scheduling. Limit noise -generating construction activities to daytime, weekday hours (7 AM to 6 PM) and 9 AM to 5 PM on weekends and holidays. When construction is occurring within 100 feet of existing residences, then construction shall be prohibited on Sundays and Holidays. • Equipment. Properly muffle and maintain all construction equipment powered by internal combustion engines. • Idling Prohibitions. Prohibit unnecessary idling of internal combustion engines. • Equipment Locations and Shielding. Locate all stationary noise sources - generally equipment such as air compressors - as far as practical from existing, nearby noise sensitive receptors. • Quiet Equipment Selection. Select quiet construction equipment, particularly air compressors, whenever possible. • Noise Disturbance Coordinator. Designate a project construction supervisor as "Noise Disturbance Coordinator" who will be responsible for responding to any local complaints about construction noise. The Disturbance Coordinator will determine the cause of the noise complaint and institute reasonable measures to correct the problem. Conspicuously post a telephone number for the Disturbance Coordinator. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The mitigation ensures that construction activities are limited to the least noise sensitive time of day, that equipment is outfitted with noise reducing devices, and stationary noise sources be located as far as possible from sensitive receptors. Implementation of these measures will ensure that construction noise impacts will be reduced to less than significant. Therefore, after applying this measure, the impact would be less than significant. Resolution No. 2014-126 N.C.S. Page 12 Impact 4.8-4 — Rail Crossing: The project will result in an increase in daily and peals hour trips, but would not substantially increase hazards due to conflicts between motorists, pedestrians, bicyclists and rail operations. However, if supplemental safety measures to be implemented as part of the SMART rail service are not in place before project completion, potential hazards could result. TRAF-1: If SMART rail service (and the supplemental safety measures that may be needed for it) is delayed to such an extent that the Riverfront project is built first, require installation of the supplemental safety measures at the existing Caulfield Lane at - grade crossing to include an additional exit gate on the southwest side of the crossing to preclude vehicles from navigating around the entry gates to proceed eastbound on Caulfield. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The mitigation ensures that safety measures are installed for the Caulfield Lane at -grade crossing to facilitate increased activity, including pedestrian, cyclists and motorists, at that intersection, which provides for an additional exit gate. Implementation of this feature will ensure that safety concerns associated with the existing at -grade crossing will be reduced to less than significant. Therefore, after applying this measure, the impact would be less than significant. Cumulative Impact — Traffic: The project will contribute to significant cumulative near -terns impacts. CUM_ 1. Require payment prior to recordation of the Final Map of the project's 21 % pro -rata share of the cost of signalization at Hopper Street/Caulfield Lane in the future when an extension of Caulfield Lane over the Petaluma River is completed. CUM -2. The Applicant shall lengthen the westbound left turn pocket at Lakeville Street/Caulfield Lane to approximately 250 feet, and install a raised median on the westbound approach to physically prohibit illegal left turn movements into and out of adjacent properties, as recommended in the project traffic report, in order to improve capacity and safety at the intersection. Impact After Mitigation: Less than Significant Finding: Changes or alteration have been required in, or incorporated into the Project, which avoid or substantially lessen the significant environmental effect identified in the EIR. Rationale for Finding: The mitigation recognizes that the project will contribute to cumulative traffic related impacts and requires that fees and improvements be provided to cover the project's share. Implementation of these measures will ensure that cumulative traffic impacts will be reduced to less than significant. Therefore, after applying this measure, the impact would be less than significant. Resolution No. 2014-126 N.C.S. Page 13 EXHIBIT B MITIGATION MONITORING AND REPORTING PROGRAM MITIGATION MONITORING AND REPORTING PROGRAM PROCEDURES Section 21081.6 of the Public Resources Code requires a Lead Agency to adopt a "reporting or monitoring program for the changes made to the project or conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment" (Mitigation Monitoring and Reporting Program, Section 15097 of the CEQA Guidelines provides additional direction on mitigation monitoring or reporting). The City of Petaluma (the "City") is the Lead Agency for the Riverfront Mixed -Use Development and is therefore responsible for enforcing and monitoring the mitigation measures in this Mitigation Monitoring and Reporting Program (MMRP). A Draft Environmental Impact Report (DEIR) has been prepared to address the potential environmental impacts of the project. Where appropriate, this environmental document identified project design features or recommended mitigation measures to avoid or to mitigate potential impacts identified to a level where no significant impact on the environment would occur. This MMRP is designed to monitor implementation of the required mitigation measures and conditions set forth for project approval for the proposed project as identified in the Draft Environmental Impact Report (DEIR) and the Final Environmental Impact Report (FEIR). The mitigation measures as well as the conditions set forth for project approval are listed and categorized by Section with an accompanying identification of the following: • Implementation Action: Describes how the measures will be implemented. • Monitoring/Reporting Responsibility: Identifies the party that is responsible for implementing and enforcing the measure, and the agency to which reports involving feasibility, compliance, implementation and development are made. • Timing Requirements: Specifies the stage at which the measure is in effect and identifies the duration that the measure remains effective including pre -construction, construction and operation. • Reporting Requirements: Identifies the reporting method to ensure compliance with measure. The MMRP for the proposed project will be in place throughout all phases of the project. The project applicant shall be responsible for implementing all mitigation measures unless otherwise noted. The applicant shall also be obligated to provide certification, as identified below to the appropriate monitoring agency and the appropriate enforcement agency that compliance with the required mitigation measure has been implemented.
