CITY OF BURLINGAME A municipal corporation City Manager ATTEST: City Clerk Approved as to form: City Attorney Consultant EA Exhibit "A" BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22,1998 SCOPE OF WORK The following scope of work reflects our current understanding of the substantive requirements for the Gap Closure EIR. It does not preclude subsequent modifications which may be warranted by unforeseen events that may arise during the EIR preparation and review process. GENERAL APPROACH The basic approach to preparing the EIR will be to utilize as much information as possible from the draft Initial Study previously prepared by Nolte and Associates. The discussion from the Initial Study will be reworked and supplemented as necessary to meet the substantive requirements of CEQA for EIRs. The EIR analysis will be focused on those subjects for which potentially significant impacts may occur. The EIR will include a section entitled "Impacts Found Not to be Significant" with brief explanations of each of the topics not addressed in detail in the EIR. An Initial Study Checklist will be appended to the EIR which indicates the determinations made in focusing the EIR analysis. TASK 1 - NOTICE OF PREPARATION/SCOPING MEETING The first work product to be prepared will be the Notice of Preparation (NOP). As required under CEQA, this document will include a description of the project, including location maps, as well as a summary of issues to be addressed in the EIR. The NOP will include notice of a public scoping meeting to be held by the City. The draft NOP will be submitted to the City for review and concurrence prior to finalization. The City staff will distribute the NOP to state, regional, and local agencies and organizations, as well as affected property owners, to solicit environmental concerns regarding the project. Prior to commencing work on the EIR, a scoping meeting will be held to solicit public input on issues that should be addressed in the EIR. At the scoping meeting it is assumed that Callander Associates will introduce and describe the project, and Nolte staff will summarize the main environmental issues, solicit input, record comments, and respond to general questions relating to the EIR process. Nolte and Associates will prepare a written summary of the issues raised at the scoping meeting. If the scoping meeting results in an expansion of this scope of work, a contract amendment may be required to cover the additional effort. SEP 2 3 1998 DEPT. OF PUBLIC WORKS CITY OF BURLINGGAME n:lsj0468kwin\Rev2_E IR_smpe.doc BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22,1998 TASK 2 - PREPARE ADMINISTRATIVE DRAFT EIR The ADEIR will be prepared in accordance with the requirements of CEQA and the City of Burlingame. The content of the EIR and the scopes of the topic areas are described below. PREFACE/INTRODUCTION This brief introductory section will discuss the legal authority for preparing the EIR under CEQA and the City's environmental review requirements. Included will be a listing of issues to be addressed in detail in the Focused EIR, as well as a list of potential environmental effects which were found not to be significant and therefore are not given detailed analysis. This section will also include an overview of the environmental documentation and review process to be undertaken for the project through to certification of the environmental document. SUMMARY As required by CEQA for EIRs, this section will include a brief project description and a summary table that lists all of the potential impacts identified in the EIR by topic, along with the corresponding mitigation measures and the level of significance after mitigation. PROJECT DESCRIPTION The description of the project will begin with a discussion of the purpose and need for the project, and an overview of existing conditions on the site and the surrounding area. The description of the project itself will include a detailed discussion of the proposed ultimate project as well as the interim project consisting of an at grade trail with no shoreline improvements. The alternatives to the project will also be described. The discussion in this section will be largely drawn from the material contained in the draft Initial Study, with revisions made as necessary to reflect project modifications and refinements. In addition, this section will contain a statement of project objectives, as required under CEQA, and a listing of discretionary approvals required for the project from local, regional, state, and federal agencies. CONSISTENCY WITH PLANS, POLICIES AND REGULATIONS This section will evaluate the consistency of the project with applicable local, regional, state, and federal plans programs and regulations. The discussion of consistency with the City's General Plan and zoning, and BCDC's San Francisco Bay P1 an will be drawn from the draft Initial Study. In addition, new discussions will be prepared on applicable regulations and requirements of the California Department of Fish and Game, U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and other agencies with potential jurisdiction. n:\sj0468\win\Rev2_El R_srope.doe BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22, 1998 ENVIRONMENTAL SETTING, IMPACTS AND MITIGATION MEASURES This is the main chapter of the EIR and will include separate sections for each environmental topic to be addressed, with the discussion for each topic formatted under the subheadings Environmental Setting, Impacts, and Mitigation Measures. Findings will be made as to the level of significance of each impact after mitigation.. Much of this discussion will be based on information contained in the draft Initial Study, although the analysis will need to be substantially reworked to fit the EIR format. In addition, new analysis will be added in the areas of wave reflection impacts and biotic resources. The analyses will address potential impacts of both the ultimate and interim projects. The specific scopes for each topic are described below. LAND USE This section will begin with a description of land uses within and adjacent to the trail alignment. The completed project will not incompatible with adjacent uses; however, the right-of-way requirements for the trail will involve acquisitions of property from adjacent landowners. The details of the right-of-way requirements will be described in the project description. This section will evaluate the impacts of the right-of-way take on the continued operation of the businesses involved, and will also discuss the temporary land use impacts resulting during the construction phase. This will focus primarily on parking impacts and circulation issues. This section will largely draw on the land use analysis in the draft Initial Study, with reorganization of text to EIR format. GEOLOGY This section will describe existing geological conditions along the trail alignment, the potential geologic hazards affecting the project, and slope stability issues along the shoreline. An issue of particular concern is the potential for "mud wave" and related ground settlements due to the underlying soft bay muds. It is assumed that additional geotechnical investigation will be undertaken to further define this issue and formulate appropriate design recommendations, which may result in project design modifications (e.g., extension of rip -rap below 6.42 msl). Such modifications may necessitate supplemental analysis in related subject areas (e.g., wetland impacts). Some of the discussion of geologic impacts will be drawn from the draft Initial Study and supporting geotechnical report; however, the discussion of mud wave impacts will be new to the EIR. It is assumed that any supplemental geotechnical investigation will be undertaken directly for the City, or under a separate request and not as part of this scope of work. HYDROLOGY This section will discuss flooding potential and the flood protection measures incorporated into project design for both the ultimate an interim projects. This discussion will be based on n:\sj0468\win\Rev2_EIR_scope.doc BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22,1998 previous work prepared for the draft Initial Study, with reorganization of material for the EIR format. Also included in this section will be a new discussion on wave reflection, particularly the potential for the proposed rip -rap slope protection to alter wave energy patterns. The primary concern is with potential scour erosion on the existing tidal marsh located just offshore from the trail alignment. As part of this scope of work, Nolte and Associates will retain the engineering firm of Moffatt & Nichol to undertake this technical analysis. The results of the analysis will be discussed in the EIR and provided to the biological consultant for use in the analysis of potential habitat impacts. BIOLOGICAL RESOURCES A preliminary biological survey and report was previously prepared by Environmental Collaborative, the findings of which were discussed in the draft Initial Study. This discussion will be utilized in the EIR discussion of biological resources, and reformatted as necessary. In addition, Nolte and Associates will retain the wetlands consulting firm of Ted Winfield and Associates to analyze the potential impacts of the proposed revetment upon cordgrass marsh just offshore, based on the results of the wave reflection analysis to be undertaken by Moffat & Nichol. Winfield and Associates will also consult with the U.S. Army Corps of Engineers concerning the extent of possible Corps jurisdiction and the type of authorization that will be needed for the pedestrian bridges. It is assumed that the project footprint will place some fill into waters of the U.S. to the toe of the slope extending below 6.42 msl. The EIR will include a discussion of these issues based on the technical reports prepared. Subsequent to the preparation of the draft Initial Study, concern was raised regarding the potential for federally protected species such as the clapper rail and salt marsh harvest mouse to be present in the project vicinity. Although the report by Environmental Collaborative preliminarily concluded that suitable habitat for these species is not present in the vicinity, Nolte and Associates will retain the ecological consulting firm of H.T. Harvey & Associates (who are experts on these species) to confirm these findings. Harvey & Associates will conduct a field survey to assess the adjacent habitat for potential for these species to be present, and will also coordinate with the U.S. Fish and Wildlife Service to determine whether further survey work may be required. It is possible that the Service could require detailed protocol -level surveys for one or both of these species. (Such surveys are not included in this scope of work and would require a contract amendment.) The EIR will include a discussion of this issue based on a report to be prepared by Harvey & Associates. CULTURAL RESOURCES Although there is an extremely low probability that cultural materials exist in the project area, the EIR must acknowledge the potential for such resources to be present. The EIR will identify the n:\sj0468\W nXRev2_E I R_scope.doc BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22,1998 appropriate mitigation, which will consist of the standard requirement to stop construction in the vicinity of any finds until an archaeologist is consulted. HAZARDOUS MATERIALS Research conducted for the draft Initial Study determined that there is an existing site of soil and groundwater contamination at the BP property at the southern end of the project. The discussion from the draft Initial Study will be utilized and updated based on telephone inquiries to be made with the County Health Department. CONSTRUCTION IMPACTS Potential construction impacts such as noise and dust generation and soils erosion will be addressed, and standard mitigations identified. IMPACTS FOUND NOT TO BE SIGNIFICANT Based on determinations made in the Initial Study Checklist to be appended to the EIR, this section will identify topic areas where the project is not expected to result in potential impacts. Brief discussions will be provided for each topic indicating why the project impact will not be significant. The topics to be covered include: Population and Housing Air Quality Transportation/Circulation PROJECT ALTERNATIVES Energy and Mineral Resources Noise Public Services Utilities and Service Systems Aesthetics Recreation The EIR will contain a detailed analysis of project alternatives as required under CEQA. This scope of work includes the analysis of three alternatives as follows: 1) No project (as required by CEQA); 2) Pathway with continuous seawall (instead of elevated trail with rip -rap); 3) Off -shore Boardwalk Alternative (suggested by Norbert Dahl). These alternatives will be evaluated in terms of their relative impacts compared to the proposed project. Also, the Environmentally Superior Alternative will be identified and briefly discussed as required by CEQA. The alternatives will also be evaluated in terms of their capability to meet the project objectives. n:W0468\winlRev2_EI R_scope.doc BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22, 1998 CEQA-MANDATED SECTIONS The EIR will include brief evaluations under the following topic headings, as required by CEQA: • Cumulative Impacts • Growth -Inducing Impacts • Significant Unavoidable Impacts and Irreversible Changes VIEWS OF LOCAL GROUPS AND INDIVIDUALS This section will summarize the public comments received at the public scoping meeting and in response to the Notice of Preparation. MITIGATION MONITORING PROGRAM This scope of work includes the preparation of a Mitigation Monitoring and Reporting Program as required under Section 21081.6 of the Public Resources Code. The program will enumerate mitigation measures specified in the EIR, identify the parties responsible, and indicate the time frame for implementation of monitoring for each mitigation measure. The monitoring program will be included in the successive drafts of the EIR. EIR APPENDICES The text of the EIR will be followed by the EIR appendices, which will include the completed Initial Study Checklist, the Notice of Preparation (and any responses to the NOP), the written summary of issues raised at the public scoping meeting, and the technical reports prepared for the EIR (including those originally prepared for the draft Initial Study). PRINTING AND DELIVERY Upon completion of the ADEIR, five copies of the document and accompanying technical appendices will be printed and delivered to the City staff for their review. TASK 3 - REVISE ADEIR Based on comments received from the City staff, the ADEIR will be revised. Although minor changes to the Project Description may occur at this stage, it is not anticipated that the changes n:\sj0466\w(n\Rev2_EIR_scope.doc BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22, 1998 will be of such magnitude as to require major revisions to the EIR or the technical studies. No input from technical consultants is expected at this stage or beyond and none is included in this scope of work. Upon completion of the Revised ADEIR, two copies of the document will be printed and delivered to the City staff for their review. TASK 4 - PREPARE DRAFT EIR Based on staff comments received on the Revised ADEIR, a preliminary Draft EIR will be prepared which incorporates any changes requested. The revised pages of the document will be forwarded to staff for their final review and concurrence prior to printing and circulation of the Draft EIR. A total of 40 copies of the DEIR will be produced. Two copies will be submitted to the City, along with one reproducible copy, and one electronic copy (in Word for Windows). The 45 -day public and agency review period will commence once the documents are submitted to the State Clearinghouse and made available for public review. Nolte and Associates will take responsibility for forwarding 10 copies of the DEIR to the State Clearinghouse. Nolte will distribute the DEIR to local agencies and interested parties, with names and addresses for distribution to be provided to the City. TASK 5 - PREPARE FINAL EIR At the conclusion of the 45 -day review period, Nolte and Associates will review the comment letters received and coordinate with the City staff to discuss the general approach to be taken in preparing responses. We will then prepare draft responses to comments, along with an addendum section indicating any revisions made to the EIR. (We will also prepare a summary of the comments received on the City Council hearing on the EIR, and prepare written responses to those comments.) Upon completion, two copies of the Administrative Final EIR will be submitted to the City for review. Based on the comments received, final revisions to the document will be made. At that stage, the Final EIR will be produced, which will contain the comment letters, the responses to comments, and the EIR addendum. A total of 40 copies of the FEIR will be submitted/distributed, along with one reproducible copy and one electronic copy. With respect to the level of effort required to respond to the comments, it is anticipated that approximately 40 hours of professional time (or $2,600) will be required, based on our previous experience with projects of similar scope and complexity. However, the volume of comments that will be received and the level of effort required to respond to those comments may exceed this expectation. If a substantially greater effort than can currently be foreseen is required to respond to comments, such additional efforts will be considered extra work billable at standard charge rates. n:\sj0468\win\Rev2—ElR—soope.doc BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22, 1998 TASK 6 - DESIGN TEAM SUPPORT The design team will support the EIR process by providing updated exhibits as required for the project. It is anticipated additional technical information will also be required. This task allows for 32 hours of Nolte design team support during this process. As part of this task, Lowney Associates, as a subconsultant to Nolte and Associates, will supply preliminary geotechnical investigations in accordance with their attached scope. In addition to the alternatives discussed in this referenced scope, the additional alternative of a trail on existing grade with no slope protection will be discussed by Lowney in their report. CITY COUNCIL HEARINGS It is expected that the City Council will hold one hearing on the EIR during the 45 -day review period, and another hearing at the end of the process to certify the EIR. Bert Verrips of Nolte and Associates will attend both Council Hearings and respond to questions on the EIR as directed by staff. AGENCY COORDINATION This scope of work includes preliminary coordination with BCDC regarding their concerns, and with federal resource agencies such as the U.S. Arany Corps of Engineers and the U.S. Fish and Wildlife Service to discuss jurisdictional wetlands and endangered species. This does not include any efforts required to obtain a Section 404 permit from the Corps for possible filling of wetlands, nor does it include coordination under Section 10a of the federal Endangered Species Act to authorize possible work in endangered species habitat. Likewise, this scope of work does not include efforts to obtain a permit from BCDC, nor does it include the preparation and processing of a Section 1603 Streambed Alteration Agreement from the state Department of Fish and Game. SCHEDULE The following schedule sets forth the estimated time requirements for each step in the EIR preparation, review and certification process. There may be opportunities to expedite this schedule if the process runs smoothly and the volume of revisions and continents is less than expected. n:\sj0468\win\Rev2_E I R_scope.doc BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22,1998 Task/Step Nolte Prepares NOP Material Duration Target Date 1 week August 24 City Issues NOP & Notice of Scoping Mtg 1 week September 1 City Holds Public Scoping Meeting 2 weeks September 14 Commence Technical Studies - - September 14 NOP Comment Period Closes Prepare Technical Studies/ Coordinate with Agencies Nolte Completes Admin.

Nolte's efforts will be charged on a time -and -materials basis, so the actual budget required may vary from the estimate. The following table provides a breakdown of this fee estimate by task and subconsultant. These items are discussed in greater detail in the scope of work. The budget estimate is subject to the notes and assumptions listed below the table. TASK BUDGET Nolte and Associates 1. NOP/Scoping Meeting $1,000 2. Prepare ADEIR 9,000 3. Revise ADEIR 3,000 4.

Additional efforts beyond these parameters may be subject to a contract amendment. 1. The scope of work will not change significantly as a result of issues raised at the public scoping meeting. 2. Once the preparation of the EIR has begun, no major changes to the project description or the scopes of the technical studies are anticipated. 3. Two iterations of the Administrative Draft EIR are included (ADEIR and Revised ADEIR). 4. A total of 40 hours of professional time ($2,600) has been budgeted for preparation of the draft Responses to Comments on the Draft EIR. 5. The subconsultants' scopes and fee estimates include a small amount of effort to assist with revisions and responses to comments. It is not expected that any of the technical subconsultants will be required to attend the scoping meeting or any public hearings. 6. The number of documents produced at each stage in the EIR process will be limited to the numbers enumerated in the scope of work. Attendance at the public scoping meeting and two public hearings before City Council is included. 8. The scope of work for Winfield and Associates includes determination of extent of possible wetland jurisdiction of the U.S. Army Corps of Engineers and consultation with the Corps concerning the type of authorization needed for the pedestrian bridges and placement of rip rap below 6.42 msl. However, the scope of work does not include a formal wetlands delineation or any efforts to prepare and process an application for a Corps permit. 9. The scope of work for H.T. Harvey and Associates includes a general habitat evaluation for listed species and preliminary coordination with the U.S. Fish and Wildlife Service to determine whether additional protocol -level surveys for these species will be required by the Service. The scope of work does not include conducting such protocol surveys or any formal coordination that may be required to obtain authorization to work in endangered species habitat. 11 n:\s10468\win\Rev2_El R_scope.doc BURLINGAME BAYFRONT BICYLE/PEDESTRIAN GAP CLOSURE FOCUSED EIR SCOPE OF SERVICES (Revised) - September 22,1998 10. The scope of work includes preliminary coordination with BCDC, the California Department of Fish and Game, and other agencies which may have authority concerning the project. The scope of work does not include any efforts required to obtain permits or authorizations from such agencies. 11. The schedule for preparation and processing of the EIR will proceed expeditiously without prolonged periods of inactivity which would create inefficiencies due to stopping and starting work. 12. This scope of work assumes design support will consist of utilizing existing available information to prepare exhibits, supplement data and support the EIR process. No new geometric or analysis work is anticipated. 12 n:\sJ0468\win%Rev2_ElR_scope.doo Attachment to Focused EIR Scope of Services (Revised 9/22/98) CITY OF BURLINGAME DEPARTMENT OF PUBLIC WORKS 501 Primrose Road Burlingame, California 94010 Attention: Mr. Chris Metzger / Nolte Ms. Jane Gomery / City Ladies and Gentlemen: September 11, 1998 P8531 RE: AGREEMENT FOR PRELIMINARY GEOTECHNICAL INVESTIGATION BAYFRONT BICYCLE/PEDESTRIAN GAP CLOSURE BURLINGAME, CALIFORNIA Thank you for requesting our agreement for geotechnical services for the above referenced project in Burlingame, California. We have outlined below our suggested scope of services and fee to complete a preliminary geotechnical investigation for the project based on our understanding of the desired level of effort for this phase. In preparation of this agreement, we have discussed the project with you and visited the site. For our use we also received a copy of the preliminary geotechnical review of available reports prepared by Parikh Consultants, Inc. for this project. This investigation would be conducted to provide preliminary subsurface conditions at the site and to develop preliminary geotechnical conclusions and recommendations for your planning and cost estimates for the proposed Bayshore trail. We first present our understanding of the project followed by our detailed scope of services. Our scope of services was carefully developed to rely on our familiarity with the geotechnical conditions in the area and to provide suitable data for design while minimizing overall construction costs. PROJECT DESCRIPTION We understand that the project is to consist of the construction of an approximately '/4 -mile pedestrian/bicycle trail which will complete the connection between existing sections of the trail to the north and south. The trail will be a 12 -foot wide asphaltic concrete path, constructed on a proposed embankment along the edge of the San Francisco Bay, which will have a final elevation of 10 feet above mean sea level (MSL) to provide protection from the 100 -year flood event. The proposed trail alignment will cross portions of nine parcels which will be acquired through easements. The majority of these parcels are developed commercial properties, the remainder are undeveloped vacant lots. The trail will also cross two drainage channels, the Easton Creek and an unnamed channel. The project will also include two bridges, which will cross the drainage channels, and most likely rip -rap slope protection placed along the bay side of the trail. Fills on the order of 2 to 4 feet will reportedly be required to raise the embankment to Elevation 10 feet (MSL). City of Burlingame P8531, Bayfront Bicycle/Pedestrian Gap Closure SITE DESCRIPTION The trail alignment currently consists of paved parking areas through most of the developed properties. The southern portion of the trail area contains an unimproved foot path crossing the undeveloped portions of the BP gas station property and a vacant lot. A plywood crossing serves as a temporary bridge over the unnamed drainage channel. Some trees and tall grasses are present in the undeveloped areas. The Easton Creek drainage does not have a crossing near the shoreline at this time. RECORD OF QUALITY Lowney Associates has provided geotechnical services for more than 4,000 projects over the last 29 years. Our commitment to meeting our client requirements and developing practical, cost- effective, design recommendations has allowed us to produce consistent high quality work. As a result, we are able to maintain professional liability insurance coverage of $3 million. Lowney Associates won the 1994 and 1995 first place Engineering Excellence Award for the Consulting Engineers and Land Surveyors of California, a professional organization of 1,300 engineering firms. In addition, the firm's 1997 entry received a Merit Award. The awards were for projects that resulted in significant savings (up to 80 percent) in construction cost and time using creative and innovative solutions. The firm's 1995 project was a finalist in the national American Consulting Engineers Council competition. SCOPE OF SERVICES We understand that only preliminary recommendations related to slope stability are desired at this time. For that reason, development of recommendations for foundations, earthwork, retaining walls and pavements will not be provided as part of our scope of work. Our detailed scope of services is presented below. This agreement does not include environmental services. GEOTECHNICAL INVESTIGATION FIELD EXPLORATION Exploratory Borings: To characterize the subsurface conditions, we would drill, log, and sample three exploratory borings with rotary -wash drilling equipment. All three borings would be drilled through the underlying Bay Mud to determine the thickness for our stability analysis. We would obtain relatively undisturbed and bulk soil samples from our borings for visual observation and laboratory testing. We would mark the boring locations and notify you and Underground Services Alert prior to beginning field work so that public or private underground utilities can be identified. Borings would be permitted and backfilled with cement grout in accordance with San Mateo County Environmental Health Department guidelines. We assume that all other required permits, including encroachment, would be obtained by you or the City of Burlingame. LOMEYASSOCIPITES Page 2 Fsvironmental / Geotechnical / Engineering Services City of Burlingame P8531, Bayfront Bicycle/Pedestrian Gap Closure LABORATORY TESTING We would conduct laboratory testing on the sampled soils to evaluate the engineering properties. This testing would include 1) moisture contents and dry densities, 2) undrained triaxial shear strength, and 3) other tests as necessary for analysis of slope stability. OFFICE STUDIES We would review the field and laboratory data and perform engineering analysis to evaluate on a preliminary basis the proposed embankment alternatives for slope stability. We would prepare a report that includes the results of our investigation and our preliminary conclusions and geotechnical recommendations for the proposed embankments. Our report would include a site plan, boring logs, and laboratory test data in addition to the following: Site Conditions: We would review and summarize the surface, subsurface, and ground water conditions and the engineering properties of the soils encountered during the site investigation. Slope Stability: We would evaluate the impact of two proposed embankment alternatives on the stability of the underlying Bay Mud deposits. In addition, we would also provide an opinion on the performance of the proposed alternatives, if requested. We would require scaled cross sections of the proposed alternatives for our analysis. OPTIONAL SCOPE OF SERVICES PRIVATE UTILITY LocAToR: If desired we can subcontract with a private utility locator. As noted in this proposal, we will contact Underground Service Alert (USA) as part of our scope of work so that any public utilities in the area of our exploratory borings will be marked. Please note that USA will not mark private utility locations, such as those on commercial properties. Therefore, we would need you to mark private utilities at the site or provide us with plans indicating their locations prior to drilling. We recommend a private utility locator to help reduce the risk of damaging underground utilities during drilling, especially on sites where little information is available regarding existing underground utilities. SCHEDULE We are prepared to begin work upon receiving your written authorization and would need approximately four weeks to complete our report following authorization. A tentative project schedule is attached. FEES AND TERMS We propose to provide our services in accordance with the attached Terms and Conditions of Agreement for the fixed fees itemized in Table 1. Any requested contract changes would need to LOMEI(ASSOMTES Page 3 Environmental / Geotechnical / Engineering Services City of Burlingame P8531, Bayfront Bicycle/Pedestrian Gap Closure be approved in writing before we proceed. Our costs are prepared with the expectation that the site and boring locations are accessible by conventional truck -mounted drilling equipment. We reserve the right to adjust our fees in a reasonable manner should any significant factors, such as rain, be encountered other than as represented or prevailing at the time of this agreement.

Please let us know if you would like us to provide an estimate for any additional services. FUTURE SERVICES We recommend that we be retained to review final embankment plans for conformance with the geometry used in our analysis and to provide supplemental analysis, if required. Our currently proposed analysis is based on widely spaced borings. If deemed necessary, our final review and analysis may require supplement exploration. We also recommend that we be retained to review the project plans and specifications for conformance with our recommendations and to perform geotechnical observation and testing services during construction. Although these services are not included in the above scope of services, we believe that they are important in expediting approval by governing agencies and achieving cost-effective construction. We would be pleased to provide an estimate for these services once final plans and schedules are available. 0 MV, P8531.doc LCMEYASSOCAATES Page 4 Environmental / Geotechnical / Engineenng Services UBtO6 ro .m» ASSOCIATES _ ! so e94� 6„n p_c_ LIN 2 . ¥@ \ }® . \ } ....... s..�..._. \� \ �\ Q, zƒ '... .... . .. . . +ee f ~ 7 i =C a A 6 � ..... . � ok) r\f Ie/ @ . !bo } ) Qai / co( \ { [ 2 I \ \ r § 2 A 4® w l A . = f ƒ ƒ G ± • ) # 0 j/�\. ) ? /�\ j ! . \ di ] e 0 , Q) $ o a \ \ / f \ / :3x j (\o "J 4 ) .\ Q_ e rI-J, r< w= e //
