5 SECTION 1.0 INTRODUCTION The California Quality Act (CEQA) requires that public agencies adopting environmental impact reports (EIRs) take affirmative steps to determine that approved mitigation measures and project design features are implemented subsequent to project approval. The lead or responsible agency must adopt a reporting and monitoring program for the mitigation measures incorporated into a project or included as conditions of approval. The program must be designed to ensure compliance with the EIR during project implementation (Public Resources Code, Section (a)(1)). The ing and Reporting Program (MMRP) will be used by the San Diego Water (Water ) as Lead Agency to ensure compliance with adopted mitigation measures and project design features associated with the development of the proposed Tijuana River Valley Wetlands project (project). The Water, as Lead Agency pursuant to the State CEQA Guidelines, will ensure that all design features and mitigation measures are carried out. Implementation of the project design features would lessen potential environmental impacts to below a level of significance for recreation, while implementation of project design features and mitigation measures would reduce impacts to below a level of significance for water resources, biological resources, and cultural resources. There is no feasible mitigation for impacts to agricultural resources. Section 2.0 of this document describes the approvals and permits that are not part of the MMRP, but are required to be implemented as part of the project to: (1) comply with government codes, ordinances, and regulations; and (2) reduce project effects. The remainder of this MMRP consists of a checklist that identifies the project design features and mitigation measures by resource. The table identifies the mitigation monitoring and reporting requirements, including the person(s) responsible for verifying implementation of the design feature or mitigation measure, timing of verification (prior to, during, or after construction) and responsible party. Space is provided for sign-off following completion/implementation of the design feature or mitigation measure. Tijuana River Valley 1 December 2008

15 SECTION 4.0 PROJECT DESIGN FEATURES AND MITIGATION MONITORING AND REPORTING CHECKLIST RECREATION The following project design feature has been included as part of the project: DF-R-1 Roads and trails within the TRVRP that are within the area affected by the proposed project would be closed or access restricted as necessary during construction to avoid potential safety conflicts between construction activities and recreational activities. All road and trail closures and restrictions would be well marked and alternative routes would be identified at closure points, if available. Local equestrian rental businesses would be provided with maps of alternate trails and trail closures and restrictions that can be reproduced and provided to horse rental clients. All roads and trails within the area affected by the proposed project would be restored to existing conditions, or better, following construction. Water Public Relations CM Engineer WATER RESOURCES The following project design features have been included as part of the project: DF-WR-1 Prior to the start of ground disturbing activities, the Water s construction contractor will prepare a SWPPP, subject to Water approval by appropriate agencies, to reduce or eliminate pollutants during and after construction is complete. The plan will identify all pollutant sources, including sources of sediment that may affect the quality of storm water discharges associated with construction activity (storm water discharges from the construction site); identify non-storm water discharges; identify structural and/or treatment control Best Management Practices (BMPs) that are to be implemented in accordance with a time schedule to reduce or eliminate pollutants in storm water discharges and authorized non-storm Timing of Pre During Post Cost.

16 DF-WR-2 water discharges from the construction site during construction; and develop a maintenance schedule for permanent or postconstruction BMPs that would to the maximum extent possible reduce or eliminate pollutants after construction is completed. Detailed BMPs to prevent hazardous materials impacts to water quality will be included in the project SWPPP. Standard industry measures include, but are not limited to the following: Storage of a minimal amount of hazardous materials on site and restriction of storage/use locations to areas at least 50 feet from storm drains and watercourses. Use of covered and/or enclosed facilities for all hazardous materials storage. Maintenance of accurate written inventories and labels for all stored hazardous materials. Use of berms, ditches and/or impervious liners (or other applicable methods) in material storage and vehicle/equipment maintenance areas to provide a containment volume of 1.5 times the volume of stored/used materials to prevent discharge in the event of a spill. On-site storage of absorbent and clean-up materials where they are readily accessible. Proper location and maintenance of trash and wastewater facilities. Posting of regulatory agency telephone numbers and a summary guide of clean-up procedures in a conspicuous location at or near the job site trailer. Regular (at least weekly) monitoring and maintenance of hazardous material use/storage facilities and operations to ensure proper working order. Timing of Pre During Post Cost.

17 Implementation of a Storm Water Sampling and Analysis Strategy (SWSAS) program pursuant to regulatory guidelines. DF-WR-3 The grading/construction contractor will conform to applicable National Pollutant Discharge Elimination System (NPDES) General Groundwater Extraction and Waste Discharge Permit criteria prior to disposal of extracted groundwater. While specific BMPs to address potential water quality concerns from disposal of extracted groundwater will be determined based on site-specific parameters, they will likely include the following types of standard industry measures derived from the NPDES Permit text and applicable agency/industry sources: Use of erosion prevention and sediment control devices for applicable conditions. Testing, filtering (e.g., with gravel and filter fabric media) and/or treating (e.g., by conveyance to a municipal wastewater treatment plant) of extracted groundwater prior to discharge, if required for NPDES permit conformance. Removal of groundwater for treatment and disposal by a licensed operator, if required for NPDES permit conformance. The following project mitigation measure has been included as part of the project: M-WR-1 Prior to conducting construction dewatering, the Water or designee shall obtain groundwater discharge coverage under one of the following compliance options as appropriate: an Individual NPDES Permit; or, the General NPDES Permit for Groundwater Waste Discharges from Construction, Remediation, and Permanent Groundwater Dewatering Extraction Projects to Surface Waters within the San Diego Bay Region Except for San Diego Bay (Order R ; NPDES CAG919002); or, a Waiver of Waste Discharge Requirements. Compliance with all approval Timing of Pre During Post Cost. CM Engineer X Construction Contractor Civil Engineer Tijuana River Valley 13 December 2008

18 terms and conditions shall be required. If the General NPDES Permit is selected, groundwater samples from the site would be collected. These samples would undergo an analysis of potential contaminants including, but not limited to, metals, volatile compounds, nitrogen, and coliform. The entire list of compounds to be analyzed is included in the General NPDES Permit. Groundwater containing constituents that exceed the effluent limitations set forth in the General Permit would require treatment prior to discharge into the Tijuana River. Timing of Pre During Post Cost. BIOLOGICAL RESOURCES The following project design features have been included as part of the project: DF-BIO-1 DF-BIO-2 DF-BIO-3 As stipulated in the Conceptual Wetlands Plan (2008a), a biological monitor will monitor project implementation and assess impact avoidance opportunities. Native vegetation disturbance will be limited to the construction zones as indicated by flagging. Equipment staging and refueling areas will be located away from sensitive habitat and natural drainages. All staging areas shall be accessible to Water, the project biologist, and appropriate regulatory agencies, subject to applicable safety protocol. Prior to the commencement of construction, the limits of grading will be clearly delineated by a survey crew prior to brushing, clearing, or grading. The biological monitor will check the grading limits before initiation of construction grading. The contractor(s) will be responsible to mitigate impacts to sensitive biological resources beyond those identified in this report or any subsequent reports that occur as a result of construction activities. Prior to the start of clearing and grubbing, both the Project Biologist and Engineer shall attend a site observation visit to verify existing conditions and the location of environmentally sensitive areas.

19 DF-BIO-4 DF-BIO-5 DF-BIO-6 DF-BIO-7 DF-BIO-8 DF-BIO-9 Activities will be prohibited within drainages (other than those that may occur within an approved construction zone), including staging areas, equipment access, and disposal or temporary placement of excess fill. Erosion and siltation into off site areas during construction will be minimized. The contractor will prepare an erosion control plan. The construction supervisor will be responsible for ensuring that the erosion control plan is developed and implemented. Appropriate post-construction fencing and signage will be installed to prohibit access and avoid potential impacts to sensitive resources adjacent to the site. This fencing would adhere to the Fencing and Gates recommendations provided in the ASMD, and fence locations would be approved by the Project Biologist prior to installation. Fencing would be installed at the edge of sensitive habitat areas prior to the beginning of vegetation clearing and grading. Lighting (if used) will be directed away from any native habitat and will consist of low-sodium or similar lighting equipped with shields to focus light downward on the appropriate subject. Operation of machinery adjacent to Tijuana River and associated waterways and wetland vegetation communities adjacent or on site will be minimized to avoid damage to existing biological resources except as shown on construction drawings and in allowable impact areas. Machinery refueling and or servicing must take place at designated staging areas. No dumping of debris or stockpiling of soil will occur in or near the Tijuana River floodplain except in areas designated on the construction drawings and as shown in Figure 3 of the Conceptual Wetlands Plan.

20 DF-BIO-10 DF-BIO-11 DF-BIO-12 DF-BIO-13 DF-BIO-14 DF-BIO-15 Construction access to the site will be limited to existing paved and approved roads/ routes. Native habitat areas adjacent to the mitigation site will be avoided with machinery at all times. Fire abatement equipment must be present on site when machinery is being operated. Non-native and/or invasive plant species present within the project area will be removed in a manner that limits the potential spread of seeds or rhizomes to adjacent areas of undisturbed native habitats. Soils containing the seeds and/or rhizomes of non-native and invasive species will be moved within the dry season if possible to prevent their spread to adjacent habitat areas or areas downstream of the project site through the water column. Plants with windborne seeds will be clipped and bagged prior to site grading. The proposed project will include regular site maintenance including removal of or treatment of non-native and invasive plant species throughout the project site for a minimum of five years after installation. A management plan will be established and funded for the mitigation bank that will provide site management in-perpetuity to ensure that the site is not dominated by non-native or invasive plant species. A SWPPP shall be developed to address potential impacts to water quality during construction, and a Water Quality Management Plan will be developed if required to ensure that impacts to water quality on a long-term basis will be avoided and minimized. All project grading will be subject to the typical restrictions and requirements that address erosion and runoff, including the federal Clean Water Act, NPDES, and preparation of a SWPPP.

21 DF-BIO-16 DF-BIO-17 DF-BIO-18 The SWPPP would contain a site map showing the construction site perimeter, temporary roadways, general topography both before and after construction, and drainage patterns across the project. The SWPPP would list BMPs that the project would use to protect storm water runoff and the placement of those BMPs. General BMPs include erosion controls, sediment controls, tracking controls, wind erosion control, non-storm water management, and materials and water management. Additionally, the SWPPP would contain a visual monitoring program and a chemical monitoring program for "non-visible" pollutants to be implemented if there were a failure of BMPs. Any planting stock used will be inspected by a qualified biologist to ensure that it is free of pest species that may invade natural areas, including, but not limited to, Argentine ants, fire ants, and other pests. Any planting stock that is infested would not be allowed within restoration areas or within 300 feet of native areas unless documentation is provided to the Wildlife Agencies, that these pests already occur in the native areas around the project site. The stock would be quarantined, treated, or disposed of according to best management principles by qualified experts in a manner that precludes invasions into native habitat. Prior to issuance of a Noticed to Proceed (NTP), the Assistant Deputy Director (ADD) Designee of the city of San Diego s Entitlements Division shall verify that s for Biological Resources have been included in entirety on the submitted construction documents and contract specifications, and included under the heading, Requirements.

X Water CM Engineer X X Construction Contractor CM Engineer; The following mitigation measures have been included as part of the project: M-BIO-1 To minimize potentially significant direct impacts to sensitive wildlife species to a level below significance, clearing of habitat on the project site shall be completed prior to the onset of the avian nesting season (January 15 July 31 for raptors; March 15 - September 15 for riparian avian species) or implementation of the following nest avoidance measures. A nesting bird survey, for species protected under the MBTA and/or California Fish and Game Code, shall be conducted within 10 days of the start of construction over the entire proposed construction area. Any actives nests found within the construction limits to be disturbed by construction clearing shall have a minimum 50-foot buffer from the nest site or an area determined to be adequate by a qualified biologist to protect the nest site(s) from work activities. Weekly surveys to assess ; Wildlife Agencies X Water Tijuana River Valley 18 December 2008

23 M-BIO-1 M-BIO-1 nest status shall be conducted until juvenile birds have successfully fledged or the nest becomes inactive. At such time, the nest site and surrounding buffer vegetation may be removed under the direction of a qualified biologist. To minimize potentially significant indirect impacts to sensitive wildlife species to a level below significance, a nesting bird survey, for species protected under the Water s draft NCCP/HCP with the potential to occur in the project area, shall be conducted within 10 days of the start of construction or at the onset of the avian breeding season (January 15 July 31 for raptors; March 15 - September 15 for riparian avian species, annually). The survey shall include a 500-foot buffer from edge of construction for raptor species. If one or more sensitive species is detected within the species-specific buffer areas, a qualified biologist shall monitor nesting activity to determine if adverse effects from construction occur. If adverse effects are observed that can be attributed to construction, the biologist will recommend changes to the construction process or active work area until breeding activity has ceased to avoid negative impacts. Weekly surveys to assess nest status shall be conducted until juvenile birds have successfully fledged or the nest becomes inactive. If construction is to occur during the breeding season for the least Bell s vireo (March 15 September 15, annually), focused protocol surveys for the least Bell s vireo shall be conducted prior to construction activities such as clearing, grading, and berm demolition and construction (or at the onset of the breeding season if construction starts before the season and is expected to continue into the season) to determine (1) if this species is present in and/or adjacent to the proposed project impact areas and (2) whether this species is located within 500 feet of the proposed construction areas.

24 M-BIO-2 developed by the project biologist in coordination with the appropriate agencies (e.g., setbacks, monitoring, breeding season construction limitation, sound attenuation walls). If construction activities must occur during the least Bell s vireo breeding season, human activities would be restricted within a 300-foot radius measured from occupied least Bell s vireo nest site(s), or a sufficient distance (as determined by the qualified biologist) such that noise levels at the nest location do not exceed 60 dba Leq (hourly average) and avoid significant indirect impacts to the least Bell s vireo. for significant direct impacts to sensitive habitat types requiring mitigation (jurisdictional wetlands and WOUS) shall be accomplished through on-site restoration, enhancement and/or creation of wetlands habitat. Prior to the project applicant commencing any activity that will substantially divert or obstruct the natural flow or substantially change the bed, channel, or bank (which may include associated riparian resources) or a river, stream or lake, or deposit or dispose of debris, waster, or other material containing crumbled, flaked, or ground pavement where it may pass into any river, stream, or lake, the applicant shall submit a complete Lake or Streambed Alteration Program notification package and fee to CDFG.

25 M-BIO-2 M-BIO-2 M-BIO-2 ratios are based on City of San Diego Biology Guidelines (City of San Diego 2004) and an evaluation of functions and services provided by existing wetlands and proposed mitigation. Disturbed southern willow scrub is considered a Disturbed Wetland in the City of San Diego Biology Guidelines and supports reduced functions and values compared with proposed mitigation and therefore the mitigation ratio for these impacts is 2:1. Open channel is considered natural flood channel and supports similar functions and services compared with proposed mitigation and therefore the mitigation ratio for this impact is 2:1. The project provides that approximately 40 acres of jurisdictional wetlands habitat be created or restored (32.3 acres of wetland acreage available to the Water and adequate acreage to mitigate project impacts). These riparian wetlands are anticipated to be under the jurisdictions of ACOE/CDFG/RWQCB/CCC/ county of San Diego/city of San Diego. The 40 acres of habitat includes a sufficient area of wetlands habitat to mitigate the direct and temporary impacts anticipated to occur to existing on-site and off-site jurisdictional wetlands during the construction phase of the project. Direct, temporary impacts to 2.77 acres of disturbed southern willow scrub under the jurisdictions of ACOE/CDFG/RWQCB/CCC/county of San Diego/city of San Diego will be mitigated at a ratio of 2:1, including 1:1 restoration and an additional 1:1 creation/restoration/enhancement within the Tijuana River watershed. ; Wildlife Agencies ; Wildlife Agencies ; Wildlife Agencies Timing of Pre During Post Cost.

A total of acre of wetlands will be created to mitigate the acre of direct impacts to sensitive vegetation communities and jurisdictional waters. The permanent impacts to southern willow scrub and mulefat scrub will be mitigated at a 3:1 ratio and the permanent impacts to open water will be mitigated at a 2:1 ratio. The created wetlands are anticipated to be under the jurisdictions of ACOE, CDFG, RWQCB, CCC, county of San Diego, and the city of San Diego. With regards to temporary impacts to acre of mule fat scrub and acre of open water, mitigation shall consist of restoration of pre-construction conditions within these work areas. A construction monitoring report shall establish preexisting conditions, conditions during construction, and conditions up to 90 days post-construction. Due to the limited nature of the temporary impacts, it is expected that vegetation communities and waters will be visibly restored to preconstruction conditions within 90 days. ; Wildlife Agencies ; Wildlife Agencies CULTURAL RESOURCES The following project design features have been included as part of the project: DF-CR-1 DF-CR-2 Prior to issuance of a Noticed to Proceed (NTP), the Assistant Deputy Director (ADD) Designee of the city of San Diego s Entitlements Division shall verify that s for Historical/Archaeology and Biological Resources have been included in entirety on the submitted construction documents and contract specifications, and included under the heading, Requirements.
