APPROACH

UNDERSTANDINGPage Mill Road in the Town of Los Altos Hills (Town) experienced storm damage during the winter of 2009/2010. High flows in Matadero Creek caused a bank failure that threatened the westbound lane of Page Mill Road. This damage occurred approximately one-quarter mile west of Interstate 280 (I-280), just downstream of the Page Mill Road Bridge over Matadero Creek (see Figure 1). The Matadero Creek Erosion Repair Project (Project) is within Caltrans’ right-of-way, and Caltrans was originally going to perform the repairs, but, after two years, turned the Project over to the Town because of an existing maintenance agreement. The Town contacted WRECO in June of 2012 asking for a repair recommendation that could be built before the upcoming 2012/2013 winter. WRECO achieved this goal by developing a strategy that would protect Page Mill Road and be designed and built before the winter of 2012/2013. This was achieved by designing a building a repair that would not encroach into jurisdictional areas of Matadero Creek. This repair consisted of a building a cast-in-drilled-hole (CIDH) pile wall approximately 75 feet in length along the edge of Page Mill Road (see Figure 2). This stabilized the roadway through the winter of 2012/2013. WRECO also developed a number of strategies (three bioengineered and three traditional structural approaches) for the Town to rebuild the west bank of Matadero Creek beneath and adjacent to Page Mill Road through the failed section such that the roadway would once again have a sufficient shoulder and provide room for a future bike lane. This design would rebuild the creek bank to an improved condition (June 2013 memorandum to the Town from WRECO) (see Figure 2).

Figure 2. Layout PLan oF Project Site


APPROACH

APPROACHThis Project will evaluate the proposed strategies previously recommended and consider other designs to determine the best solution. It is our understanding that the Town is interested in a bioengineered approach. The WRECO Team will focus on this and has already been in discussion with the San Francisco Bay Regional Water Quality Control Board Geomorphologist (Ms. Ann Riley) on the various proposed approaches. Based on this discussion, we have refined the original bioengineered designs (see Figure 3).

In order to use a bioengineered approach, the bed of the creek needs to be raised to its original elevation; otherwise, the slope would exceed the maximum 1:1. This will require filling in the bottom of the creek over a section of approximately 150 feet from 0 feet to a 3 foot maximum. This will also eliminate the 3 foot vertical drop just below the box culvert (see Figure 2). Filling the bottom of the creek will repair the recent erosional cuts and correct the oversteepened creek bank, which will prevent additional failures throughout this reach of the creek.

When the upstream double box culvert was originally constructed, the area downstream of the box culvert (for approximately 50 feet) was treated with cement for stabilization. Also, the creek was realigned so that it now crosses at approximately 90 degrees, where previously it crossed closer to a 45 degree angle. This created an additional curve back to the original creek channel of nearly 90 degrees. At this location, a drop pool approximately 3 feet deep has developed. This has created a fish passage barrier and caused the banks to be over-steepened and undermined, which has led to the failure we see currently, and unless corrected, could lead to additional failures on both sides of the creek.

The WRECO Team has already performed initial hydraulic modeling and determined that ½ ton rock would be appropriate. This rock will be placed on the bottom of the creek and at the base of the creek bank. The voids will be filled in using gravel and sand sized material compatible to current fish passage design.

Figure 3. Vegetated rSP Fill w/Coir wraPPed FaCe


APPROACH

Current ConditionCurrently, failure of Page Mill Road is prevented by a buried CIDH pile wall. This wall will protect the roadway from further damage. K-rail has been left in place because the loss of approximately 5 feet of shoulder has created a vertical drop off of approximately 12 feet into the creek adjacent to the edge of the westbound traveled way (see Figure 7).

A field visit to the Project site on January 3, 2014 revealed that additional erosion has taken place since the installation of the CIDH pile repair. The piles have supported the road as designed; however, the erosion has removed more material at the face of the piles (see Figures 4 and 5).

We noticed that some of the piles were exposed but should perform as designed to prevent a failure to the westbound lane of Page Mill Road. There has also been additional erosion to the opposite bank of Matadero Creek (see Figure 6). This erosion will continue to occur until it is remediated. Looking closely at Figure 6, there is evidence of under-cutting of the bank. This will soon cause the opposite bank to fail similarly to the current failure adjacent to Page Mill Road.

APPROACH

Potential Funding SourceSThe WRECO Team researched potential funding sources for the Project. We identified several prospective agencies and their programs below. We can perform detailed studies and outreach upon the Town’s request.

Santa Clara County Creeks CoalitionThis organization secures funding for stream restoration at a scale commensurate with the magnitude of the challenges facing the stream.

Santa Clara Valley Habitat AgencyThis agency ensures that the newly minted Santa Clara Valley Habitat Conservation Plan is enforced, and there are potential mitigation funds through them.

State of California Water Resources Control BoardThe Division of Financial Assistance administers the implementation of the State Water Resources Control Board’s financial assistance programs that include loan and grant funding for watershed protection projects, nonpoint source pollution control projects, etc.

U.S. Department of Agriculture Natural Resources Conservation ServiceThe Project might be eligible if it meets the economic, engineering, and environmental criteria. In floods, the Emergency Watershed Protection Program applies to smaller drainage areas (less than 400 square miles), whereas the U.S. Army Corps of Engineers is primarily responsible for larger systems.

Santa Clara Valley Water District (SCVWD)The SCVWD has over $794,000 in available grants to improve local creeks and watersheds in 2013. Although it may be too late to apply for these funds, we anticipate that the program will continue in 2014.

CaltransThe overpass is owned by Caltrans, which is constantly seeking mitigation for existing and future projects. It is possible the restoration of the channel and installation of fish passage designs could be funded through Caltrans as a mitigation project. With existing California red-legged frog (CRLF) occurrences downstream, Caltrans could also mitigate impacts to CRLF by enhancing the channel for CRLF aquatic and estivation habitat.


APPROACH

SCOPE OF WORKThe WRECO Team will work with the Town to design, permit, and build a bioengineered fill and creek improvement project that will not only improve the existing roadway for the proposed future bike path, but also improve the wildlife habitat in the adjacent Matadero Creek.

TASK 1 – PROJECT MANAGEMENTWRECO will provide overall management of the Project in order to ensure the Project is completed on time, within budget, and up to the Town’s standards. Work performed under this task will generally involve managing the Project; maintaining the fiscal health of the Project; providing management and supervision of the WRECO Team; maintaining the Project schedule; monitoring quality control; and attending and participating in Project meetings. This task will include the following subtasks:

Task 1.1 Project Meetings and Coordination WRECO understands that conducting meetings will be critical to the Project’s overall success. We anticipate the following meetings and coordination activities:

Project Kickoff Meeting: WRECO will hold a Project kickoff meeting, which will be attended by members of the WRECO Team and representatives from the Town.

Review Meetings with the Town: We anticipate four (4) Town-scheduled meetings and eight (8) conference calls during the development of the Project. We will likely hold the review meetings with the Town along with the Conceptual Design, 65% PS&E, 95% PS&E, and 100% PS&E submittals to discuss and clarify any Town comments.

Meeting with Permitting Agencies: Upon completion of the Conceptual Design, we anticipate one (1) meeting with the Town and the interested permitting agencies to get consensus on the design strategy.

WRECO will prepare the meeting minutes after each meeting and will submit the minutes to the Town for revision and distribution to the meeting attendees.

Task 1.2 Project Administration and Schedule For this task, WRECO will:

Create a project plan that specifies the scope of services, roles, and responsibilities of each team member Prepare monthly invoices and progress reports Maintain the Project files Perform Quality Control (QC) Maintain, monitor, and update the Project schedule Track and report job progress

The Project plan and schedule will be distributed to the WRECO Team members and the Town staff during the kickoff meeting.

QC Procedures The following QC procedures will be used in the development of the engineering documents for the Project:

Define key team members and their respective roles and responsibilities for the Project. Identify, categorize, and incorporate correspondence, memoranda, and reports prepared for the Project within a distinct filing system that enables quick recovery upon request by the Town and/or WRECO Team members.

Perform internal plan QC reviews by the Project Manager and Team Leaders to ensure that conflicts and miscommunication do not occur.


APPROACH

Perform quality assurance reviews of documents by senior staff members who are not involved with the development of the Project before submittal to the Town.

Task 1.3 Data CollectionWRECO has already accumulated a large amount of data for this Project, but the WRECO Team will review any Project material available from the Town, various utility companies, Caltrans, and other stakeholders. The Project material will include, but not be limited to, as-built plans, maintenance reports, right-of-way maps, traffic count data, previous studies, FEMA floodplain data, hydrologic data, hydraulic data, stream flow records, maintenance records for the Project site, and utility company atlas drawings that might indicate site constraints including buried and overhead utilities, etc. The WRECO Team will also identify the technical environmental studies necessary to fulfill California Environmental Quality Act (CEQA) requirements.

TASK 1 DELIVERABLES: 3 Meeting Minutes 3 Monthly Invoices and Progress Reports 3 Project Plan and Master Schedule

TASK 2 – FIELD INVESTIGATIONS AND SURVEYThe WRECO Team will perform a detailed field investigation to assess the existing conditions at the Project site. Our recent field investigation has shown that the erosion in the creek has increased. We will determine the new parameters necessary for a robust design. We will perform visual inspections, photograph the current conditions, determine unknown dimensions and elements, look for additional evidence of erosion and bank scour, and document any additional changes and/or deficiencies of the current condition of the structure and channel reach.

Mark Thomas & Company, Inc. (MTCo) will survey the creek to supplement the existing survey information that the WRECO Team has from the previous project. They will perform a topographic survey of the Project area. The survey will be tied to the North American Datum of 1983 (NAD ’83) and the National Geodetic Vertical Datum of 1988 (NGVD ’88). Features to be measured include edge of pavement, curb face, gutter lip, pavement crown, surface evidence of underground utilities, signs, overhead utilities, trees, invert and pipe sizes for gravity utilities, trees, sidewalks, fences, and walls. A base AutoCAD file will be drafted at 1:20-scale with 1-foot contours. The AutoCAD file will be used as the basis for engineering design.

TASK 2 DELIVERABLES: 3 Survey Information

TASK 3 – HYDRAULIC STUDYThe WRECO Team will update the existing hydraulic study that was performed for the previous design and preliminary creek bank improvements and document our findings in a technical memorandum.

TASK 3 DELIVERABLES: THREE (3) HARD COPIES AND ONE (1) ELECTRONIC PDF COPY 3 Hydraulic Study Technical Memorandum

TASK 4 – BIOLOGICAL RESOURCES STUDYThe WRECO Team will prepare a Biological Resources Study of the Matadero Creek region focusing on the proposed Project area. Specifically, this scope includes expenses to conduct biological resources surveys, and prepare biological assessment reports to support the CEQA documentation and resource agency applications for the Project.


APPROACH

Task 4.1 Special-Status Species ResearchThe WRECO Team will review available published biological information, including the California Natural Diversity Database, the California Native Plant Society’s Inventory of Rare and Endangered Vascular Plants, and the lists of special-status species that may occur in the Project area obtained from the U.S. Fish and Wildlife Service and the California Department of Fish and Wildlife.

Task 4.2 Site Review for Biological ResourcesUtilizing the above information, the WRECO Team will conduct surveys of the proposed Project site area to determine the presence of suitable habitat for special-status wildlife and plant species and the type of biological resources present, and to photograph and document the types of vegetation, wildlife, and aquatic features currently at the Project site.

Task 4.3 Biological Resources Analysis Report The WRECO Team will prepare a Biological Resources Analysis Report for the proposed Project summarizing the results of the field survey and analysis of potential impacts on biological resources focusing on special-status wildlife and plant species. If listed species or suitable habitats for listed species are identified on the Project site, this report will provide recommendations for avoidance and measures to reduce impacts. The report will be included with the resources agency permit applications. TASK 4 DELIVERABLES: THREE (3) HARD COPIES AND ONE (1) ELECTRONIC PDF COPY:

3 Draft Biological Resources Analysis Report 3 Final Biological Resources Analysis Report

TASK 5 – CONCEPTUAL DESIGNThe WRECO Team will prepare a conceptual design that will incorporate the existing conditions with the proposed bioengineered repair approach. We will come up with the best environmentally friendly approach to rebuild the creek bank and restore the channel to its original elevation, eliminating the 3-foot vertical drop that exists just downstream of the box culvert. This will incorporate the latest ideas in bioengineering, creek stabilization, and habitat improvement. In addition, the wildlife habitat will be improved for all to enjoy. When the conceptual design is complete, we will submit it to the Town for review. Upon approval from the Town, the WRECO Team will arrange a site meeting with the permitting agencies to discuss our approach and obtain preliminary approval before we start the design.

TASK 5 DELIVERABLES: THREE (3) HARD COPIES AND ONE (1) ELECTRONIC PDF COPY: 3 Conceptual Plan Set Drawings

TASK 6 – ENVIRONMENTAL AND TECHNICAL STUDIESWRECO and ICF International, Inc. (ICF) will be performing this task. We assume that the appropriate level of CEQA documentation required will be a Negative Declaration (ND) or Mitigated Negative Declaration (MND) and that preparation of an Environmental Impact Report (EIR) is not required. We also assume the Project could be subject to Caltrans oversight, and therefore, have included a 10% contingency on the proposed CEQA scope to accommodate additional agency review, subject to review and amendment based on the complexity of response required. We are assuming that National Environmental Policy Act (NEPA) clearance is not required, and therefore, no budget has has been allocated for this.

Task 6.1 Initiate Project/Draft Project DescriptionThis task includes reviewing the existing background information, meeting with the Town, and preparing the Project description.


APPROACH

The WRECO Team will review the existing design information. Following review of the background information, we will contact the Town staff to obtain any additional information needed to clarify and complete the Project description, which will also be included in the environmental analyses. We will meet with the Town staff to review the issues and discuss any known areas of controversy; determine the appropriate baseline conditions (existing conditions or before operational changes were made); and confirm the initial study scope of work, format, and schedule.

The Project description will summarize the location, setting, and characteristics of the Project. Project characteristics include Project footprints, and drainage and grading plans. It will also include general assumptions regarding construction methods and equipment to be used. The Project description will include required permits and approvals and any proposed avoidance measures, minimization measures, and on-site mitigation. These could include measures to minimize construction-related noise, dust, and traffic effects; control erosion; and protect unidentified cultural resources.

Task 6.2 Prepare First Administrative Draft Initial Study The WRECO Team will prepare the first administrative draft Initial Study (IS). The IS is intended to determine whether the Project may have a significant environmental effect under CEQA. The IS will be prepared consistent with the Town’s preferred format. It will include the Project description, location, environmental setting, environmental checklist, discussion of answers, mandatory findings of significance, and sources. The IS will be based on the existing documents and designs, as well as the other background information provided, to the extent practicable. The WRECO Team will review Town-provided technical reports and other information pertinent to the Project. A brief discussion of issue areas is described in the following paragraphs.

The WRECO Team will prepare and submit an electronic copy and five hard copies of the first administrative draft IS to the Town staff for review.

Key IssuesThe WRECO Team will prepare the CEQA checklist. Based on our current understanding of the proposed Project, we anticipate environmental issues to be addressed in the IS will be less than significant or mitigated to a less-than-significant level. We will develop a sound rationale for reaching the conclusions based on the existing information, our professional judgment, and consultation with relevant agencies and Town staff. This scope of work assumes two rounds of review of the administrative draft IS by the Town. We anticipate that we will prepare an MND. The MND will identify potentially significant effects of the proposed Project and list minimization with on-site mitigation measures that would reduce those effects to a less-than-significant level. As previously mentioned, if no significant impacts are identified, a Negative Declaration (ND) may be prepared. The WRECO Team’s scope assumes that an EIR will not be required. However, if there is substantial evidence that the Project may have a significant effect, despite mitigation, we will provide the Town with an appropriate scope and cost estimate for preparation of an EIR.

Following are specific observations for some of the issue areas based on our previous conversations with the Town staff and our knowledge of existing documents.

Air Quality/Climate Change. The IS/MND will include an analysis of air quality impacts conducted in accordance with the recommended methodologies identified by the Bay Area Air Quality Management District (BAAQMD). The air quality impact analysis will include a discussion of potential short-term (i.e., construction-generated) air pollutant emissions and long-term (i.e., operational) regional criteria air pollutant and ozone precursor emissions (if applicable). Proposed stationary sources of emissions will be discussed qualitatively. Air quality effects are anticipated to be minimal and would be limited to the construction of the new channel. The Project will not result in the construction or operation of any stationary emission sources (e.g., generators). The air quality analysis will also include an evaluation of Project effects on climate change, including extrapolation of greenhouse gas equivalents and quantification of climate change


APPROACH

impacts associated with the Project.

Biological Resources. The IS/MND will evaluate the potential impact of the Project on existing biological resources including special-status plants and wildlife, and related habitat value. Matadero Creek in the Project area provides habitat for CRLF and San Francisco dusky-footed woodrat. The IS/MND will evaluate the potential impact of the Project on these species and others that could occur in the Project region. The IS/MND will evaluate the impacts to biological resources in relation to stabilizing the creek bank and the restoration effort.

Cultural Resources. CEQA requires that public or private projects financed or approved by public agencies must assess the effects of a proposed project on significant historical resources. Significant historical resources are defined as buildings, sites, structures, or objects, each of which may have historical, architectural, archaeological, cultural, or scientific importance.

This scope assumes that no significant cultural resources will be identified or be affected by the proposed Project. This scope does not include preparation of technical studies or reports suitable for use for compliance under Section 106 of the National Historic Preservation Act.

Hydrology/Water Quality. The WRECO Team will perform a floodplain risk assessment to evaluate the potential impacts from the proposed Project to the floodplain development and habitat values. We will prepare a Location Hydraulic Study Memorandum to summarize the findings. It is anticipated that there will be no floodplain impacts from the proposed Project, and therefore, no mitigation will be required.

The WRECO Team will: 1) identify and describe the current and upcoming laws that relate to water quality, 2) describe the beneficial uses for all potentially affected waters, 3) discuss water quality objectives for all potentially effected waters, 4) collect and present any monitoring data from other agencies, 5) list potential sources of pollutants, and 6) describe the watershed, existing drainage, and hydrologic conditions. We will evaluate the water quality impacts for each proposed alignment and recommend possible minimization measures to reduce the adverse impacts to water quality. The WRECO Team will document our findings in a technical memorandum.

Geology and Soils. The geology and soils section will evaluate the general potential for geotechnical hazards, including earthquakes, seismic ground shaking, liquefaction and any soil or other geotechnical conditions requiring specialized design to mitigate hazards in the annexation areas. This will also include the applicable regulatory provisions.

Noise. The WRECO Team will describe the existing noise environment on and near the Project site. Nearby existing, noise-sensitive receptors (e.g., nearby residences) and noise sources will be identified and discussed. The analysis will include an assessment of potential short-term, temporary (i.e., construction-related) noise and vibration impacts with respect to nearby sensitive receptors and their relative exposure. Noise levels of specific construction equipment will be determined, and resultant generic noise levels at those receptors (at given distances from the source) will be calculated.

Traffic and Circulation. There will be one-way traffic control during the construction of the Project. We are assuming traffic control will be needed for approximately two weeks. There will be some construction vehicles and equipment entering and exiting the site during construction. During operation, maintenance personnel may occasionally drive vehicles to the site.

Task 6.3 Prepare Second Administrative Draft ISFollowing the Town’s review and comments of the first administrative draft IS, the WRECO Team will meet with Town staff to review comments, discuss necessary changes to the document, and determine whether final changes to the


APPROACH

proposed Project could be made to reduce significant impacts identified in the IS. The WRECO Team technical authors will review comments on the First Administrative Draft IS and make any changes necessary to the document pursuant to those comments.

Task 6.4 Confirm MNDAfter the second administrative draft IS is complete, the WRECO Team will meet with the Town to discuss the Project’s potential for significant environmental effects and proposed on-site avoidance and minimization measures as needed.

Task 6.5 Prepare Public Draft IS, MND, and NOIFollowing the Town’s review and comments of the second administrative draft IS, the WRECO Team will meet with the Town staff to review comments, discuss necessary changes to the document, and determine whether final changes to the proposed Project could be made to reduce significant impacts identified in the IS. Changes to the Project description will need to be discussed and approved by the applicant prior to circulation of the IS/MND. We will also discuss preparation of the MND and notice of intent (NOI) to adopt the MND. Our scope of work assumes that any changes to the IS will be minor and will not require additional analysis. A final public review copy of the Draft IS/MND will be submitted to the Town for final review.

The WRECO Team will submit thirty (30) double-sided, hard copies of the draft IS, MND, and NOI to the Town for distribution (one copy will be a single-sided, unbound master) and thirty (30) additional electronic copies of the Draft IS/MND on compact discs (CDs) in Adobe PDF format. The electronic file will be bookmarked to facilitate navigation by the public and agencies. The WRECO Team assumes the Town will be responsible for publicizing the availability of the draft IS/MND. The WRECO Team can also send fifteen (15) copies to the State Clearinghouse if requested by Town. When the document is sent to the State Clearinghouse for review, a 30-day public review period is required. A proposed MND is required to be sent to the State Clearinghouse when a State agency is a responsible or trustee agency, or when the project is of statewide, regional, or area-wide importance.

Task 6.6 Prepare Responses to CommentsAt the close of the public review period, the WRECO Team will coordinate with the Town to review comments received and determine whether responses are required. Although CEQA requires the lead agency to consider comments received before approving the Project, no formal written responses to those comments are required. CEQA does require the lead agency to have adequate information on record to explain why a given comment does not affect the conclusion made in the IS/ND or IS/MND that there are no potential significant environmental effects. In addition, the lead agency is required to notify in writing any commenting agencies of the date of the public hearing on the Project. Our scope assumes a minor effort to prepare responses to comments (approximately 25 comments, depending on complexity) will be required and that responses will be developed in coordination with the Town staff. We will submit an electronic copy of draft responses to the Town to finalize and distribute.

Task 6.7 – Preparation of First Draft Final IS/MNDThe WRECO Team will prepare the First Administrative Draft version of the Final IS/MND and will submit an electronic version only in MS Word format of the document to the Town for review. Graphics may be submitted in separate pdf files. Before submittal, a thorough QA/QC review will be completed by the WRECO Team.

Task 6.8 – Preparation of Final IS/MNDThe WRECO Team will submit fifteen (15) double-sided hard copies (one copy is to be a single-sided, unbound master) and twenty-five (25) electronic copies of the Draft IS/MND on CD in Adobe Acrobat PDF format. The electronic file will be bookmarked to facilitate navigation by the public and agencies.

3 Twenty-five (25) electronic copies and fifteen (15) hard copies of the Public Draft IS/MND and the NOI will be provided to Town for distribution.

TASK 7 – PERMITTINGThe WRECO Team will complete the resource agency forms and applications for all required environmental permitting, and we will negotiate the permit requirements. We assume the Town will submit the permit applications to the appropriate agencies. If needed, the WRECO Team can also submit the permit applications to the agencies. The following permits will be required:

CDFW 1602 Lake and Streambed Alteration Agreement. Pursuant to Section 1602 of the California Fish and Wildlife Code, CDFW has jurisdiction over the creek, riparian corridor, and State-listed special-status plants and wildlife species.

San Francisco Bay Regional Water Quality Control Board (RWQCB) 401 Water Quality Certification (WQC). The RWQCB has jurisdiction over waters of the State.

U.S. Army Corp of Engineers Permit Section 404 Nationwide Permit (NWP) Application. WRECO anticipates applying for NWP 13, 27 and 33. Consultation with the U.S. Fish and Wildlife Service (USFWS) for potential impacts to California red-legged frog habitat in the Project area would be required. The USACE is responsible for forwarding all application materials to the USFWS if a determination is made that a federally-listed species, or their habitat, is present at a proposed project site. The WRECO Team will prepare a biological assessment suitable for submittal to the USACE, and will follow through with Section 7 (Endangered Species Act) consultation and issuance of a Biological Opinion or concurrence letter. Section 7 consultation will be required due to the presence of California red-legged frog habitat (a population known to WRECO staff exists 0.4 miles downstream). It will take more time to go to obtain a concurrence letter or Biological Opinion (BO) from the USFWS, which is necessary before a USACE 404 Nationwide permit would be issued.

Attending pre-bid meetings or bid opening, and review of bids will also be provided, if requested.

It is assumed that the Town will advertise the Project for bidding and distribute the plans to prospective bidders. It is also assumed that the WRECO Team’s Project Manager or the Town’s project coordinator will be the designated person to receive contractor inquiries.

TASK 9 DELIVERABLES: 3 Response to Request for Information for Town to draft Addendum

TASK 10 - CONSTRUCTION PHASE SUPPORTThe WRECO Team will assist the Town as requested during the Project construction on an hourly basis at a not to exceed amount. We anticipate the work may include: submittal reviews, addressing RFIs, providing consultation and interpretation of the construction documents, assisting the Town in the preparation of Contract Change Orders during construction, and developing construction record drawings. The WRECO Team will also attend the preconstruction and other job site meetings, if requested.

Per the contractor’s proposed staging work, the WRECO Team’s Qualified SWPPP Developer (QSD) will update the Conceptual Water Pollution Control Plans in compliance with the San Mateo Countywide Water Pollution Prevention Program’s guidelines and will submit the Final Water Pollution Control Plans to be used during construction.

The WRECO Team will provide construction monitoring services. We will have one Qualified SWPPP Practitoner (QSP) and biologist on-site during in-creek work activities to oversee and monitor the work of the Contractor to ensure the Project meets the design goals while adhering to regulatory permits.

Inspections will include the documentation and photos of BMPs, recommendations for any additional BMPs, or necessary maintenance and documentation of BMPs installed.

ASSUMPTIONSThe following assumptions were made in the preparation of this scope of work and in estimating our level of effort for this Project:

33 Stage construction is required to accommodate traffic during construction.33 Additional submittals beyond those listed in the scope of work will be considered extra work.33 Plans and details will be drafted using the current AutoCAD version. Any electronic submittal of construction

drawings, if required, will be in AutoCAD format.33 Specifications will be in book format, using Caltrans Standard Specifications and Standard Special Provisions.33 All mitigation will be on-site, and the Project will be self mitigating.

FEEThe detailed breakdown of our proposed fee is shown on page 28. The WRECO Team’s proposed fee is $176,945.94. This value is slightly higher than the initial design estimate of $150,000 to $175,000 because construction monitoring ($16,180) was not considered in the original proposal.
