In March 2017, Caltrans and the City of Richmond entered into a Cooperative Implementation Agreement (CIA) for improvement to the State Highway System as a watershed stakeholder with the City's jurisdiction. Pursuant to Attachment IV of the Caltrans NDES Permit, Caltrans and the City of Richmond are to collaboratively implement the Water Capture Facility, known as a Trash Capture Project. The Contech Engineered Solutions CDS system is a below-ground, flow- through treatment device that uses multiple treatment processes including swirl concentration and continuous deflective separation to screen, separate and trap trash, debris, sediment, hydrocarbons and other pollutants from stormwater runoff. Veolia Water, in conjunction with the City of Richmond, successfully installed four such devices in 2017, 2018, 2019 and 2020/21. Another device is now being proposed at Bayview Avenue.

There is currently an available balance of $3.2M in project funds from Caltrans (approximately $600,000 of unspent funds from the 2020/21 project and a new authorization in the amount of $2,600,000), and Caltrans has asked the City of Richmond and Veolia to install another Trash Capture device using these funds. Veolia will be accomplishing the design and constructability review for this work using some of the same subcontractors from the 2019 Meeker Ditch project and the 2020/21 Cutting Boulevard project, namely Harris & Associates (Design), Contech Engineered Solutions (Equipment supplier), W.R. Forde (contractor constructability review) and Questa Engineering (testing). Upon completion of the design, as directed by the City, Veolia will solicit competitive price proposals for the installation of this trash capture device and issue a PO for Questa Engineering for Soils and backfill testing.

The location of the newly proposed device is at Bayview Avenue in Richmond between Hartnett Avenue and Ells Street (see attached map). The previous project team have all indicated availability and interest in performing this work. Since the specific site is still being determined along Bayview, included herein for the City's approval are estimated costs for the same project team based on the Meeker Ditch and Cutting Boulevard projects adjusted for 2021/22. Caltrans has agreed to reimburse the City for the cost to install this trash capture device, which includes testing and any additional services required. The total authorized amount for this TA is $2,000,250.25 which includes Veolia's 16.5% mark-up and is well within the remaining CalTrans fund balance of $3,200,000. When specific proposals are received and the project is bid, this TA can be revised to the not-to-exceed amount of the $3.2M balance. Per the CIA, the Trash Capture Project is exempt from the California Environmental Quality Act (CEQA), pursuant to CEQA guidelines Section 15301(b) because it is a project constructing minor alterations to an existing publicly owned utility involving negligible or no expansion of an existing use.

Bayview Avenue Trash Capture at Carlson Boulevard
Dear Chandrasekar:

The Harris & Associates team is ready to assist Veolia and the City of Richmond with the design of a trash capture device at Bayview Avenue. This scope and fee is to design the project as discussed during our team conference calls on June 24, 2021 and June 28, 2021, and our recent experience working on the Cutting Boulevard Trash Capture Project.

The following outlines our proposed scope of services and estimated fee to provide these services.

PROJECT UNDERSTANDING
In an effort to improve the environment and adhere to the increasing requirements of the Municipal Regional Permit, the City of Richmond, like many other municipalities, is working towards reducing the amount of debris discharged to the bay from its storm drain system.

According to record drawings from Caltrans, the storm drain pipes in Bayview Avenue approaching Carlson Boulevard consists of one 72" CSP pipe, one 36" RCP and two 66" RCP pipes. The 72" CMP pipe carries the stream flow and does not require treatment. The purpose of this project is to treat the flows from the two 66" RCP storm drain lines. It is not logistically feasible to treat the 36" RCP storm drain pipe as part of this project.

To that end, the City /Veolia plans to install a pair of trash capture devices in Bayview Avenue to treat these two storm drain pipes. During our planning meeting with Veolia and City, it was decided to focus on a specific corridor in Bayview Avenue, from 40' south of Harnett Avenue to 50' north of Ells Ave., where potential for utility conflicts are minimized. This corridor is shown on the attached map. The segment between Carlson Boulevard and Hartnett Avenue is not included in the study because it has quite a few underground utilities and therefore offers no space for installation of CDS devices.

It is also likely that it may be infeasible to install the trash capture devices within the identified limits. In which case, an amendment will be issued to search for another suitable location. Harris team will determine the feasibility of installing these devices after the location of the existing underground utilities are identified by our utility locating The trash capture devices and weir structure would be manufactured by Contech Stormwater Solutions and procured by Veolia.

The project will involve preparation of Plans and Specifications for the construction and installation of the Contech units and weir structure. This work will include utility investigation, topographic survey, geotechnical investigation, coordination with Contech on the final structure design, incorporating Contech's drawing into our bid documents, laying out the structure and tie-ins to adjacent drainage facilities, preparation of documents for bidding, and design services during construction.

SCOPE OF SERVICES
Scope of Services
Harris and Associates will prepare bid documents showing the proposed location and clearly defining the project parameters for bidding. We will coordinate with the City, Veolia, and Contech to design a structure that will be effective and easy to maintain.

Primary project tasks include:

1. Reviewing record drawings of the existing storm drain system in the project area.

2. Gathering and reviewing utility maps.

3. Subsurface utility investigation.

4. Topographic survey.

5. Geotechnical investigation to determine shoring and dewatering parameters.

6. Site investigation

7. Coordination with subconsultants

8. Coordination with Contech.

9. Feasibility study to determine location of the box and tie-ins to existing facilities.

10. Rough hydraulic calculations to assist Contech with sizing the CDS units

11. Providing a preliminary and final design package, including plans and specifications

12. Meeting with Veolia

13. Bid period services, including attendance at the pre-bid meeting, answering bidder questions, and preparation of 1 addendum.

14. Attendance at the pre-construction meeting.

15. Review of submittals, requests for information, and change order requests.

16. Preparation of record drawings.

17. If preliminary investigation demonstrates that the current site is infeasible, an addendum will be negotiated for exploring an alternative site.

Because the geotechnical investigation for the adjacent site revealed presence of bedrock, the scope of work for this project will include 3 to 4 borings to depth of 30 to 40 feet over 2 days to collect sufficient data to identify the limits of bedrock.

Additionally, the scope of work for utility locating include confined space entry to identify the edges of the two 66" RCP pipes. This is particularly critical for determining if sufficient space will be available for installation of trash capture devices.

The scope of work for our subconsultants are described in their proposals included in the attachment.

Assumptions and Exclusions
It is assumed that Contech will design and manufacture the trash capture devices and incorporate design flows from the City. Permitting and coordination with regulatory agencies are not included. We understand that Veolia will be providing construction management. Water Pollution Control and Traffic Control plans are not included.

In the absence of updated hydraulic data, Harris will use the hydraulic information from the City's Storm Drain Master Plan, dated November 2006, to the extent possible. Harris is not responsible for the accuracy of the data contained in the Master Plan. If needed, Harris team will attempt to conduct localized hydraulic calculations to assist Contech with the parameters needed for sizing the CDS devices. These calculations will be rough in nature. Harris does not have the means nor the institutional knowledge to perform hydraulic modeling.

Re: Proposal for Geotechnical Services
Richmond/Veolia - Bayview Trash Capture
Richmond, California
Introduction and Project Description
As requested, we are pleased to propose our geotechnical engineering services for the proposed trash capture structure located northwest of the intersection of Carlson Blvd. and Bayview Avenue in Richmond, California. We understand this project includes temporary shoring, installation of a precast below grade structure and backfill. The majority of the project site is located in alluvial soils, with fractured Franciscan chert Bedrock mapped to the northeast. Harder greenstone bedrock is mapped further to the northeast.

Scope of Services
We customarily provide our services in phases to correspond with project development. Based on our understanding of the project, we propose the following scope of services:

Phase 1 -Geotechnical Investigation
Our Phase 1 services will include review of available, published geologic mapping and geotechnical background information from our files and any geologic/geotechnical background information supplied by you. We will perform a site reconnaissance to observe and document existing conditions and pre-mark the site for utility location by USA North as required.

Subsurface exploration at the site will include obtaining a drilling permit from the County, and three to four borings drilled over 2 days with a truck mounted auger rig to collect soil samples for laboratory testing to determine the engineering properties of the underlying soils. We have estimated a boring depth of 30 to 40 feet (depending on location).

Based on our subsurface exploration, we will prepare geotechnical recommendations and criteria for the project summarized in a letter report addressing the following:
• Regional and local geologic conditions;
• Subsurface exploration and laboratory testing;
• Opinion regarding project feasibility and primary geotechnical considerations; • Criteria for grading, including discussion of anticipated excavation conditions (soil and groundwater) and backfill options and compaction requirements; • Underground utility construction, including Cal/OSHA soil-type categorization and shoring requirements;
• Foundation and retaining structure recommendations and criteria; • Pavement sections;
• Other geotechnical items pertinent to the project.

Our report will also include our boring logs and other plates and figures as needed to support our conclusions and recommendations.

Phase 2 - Supplemental Consultation and Review
Following completion of our Phase 1 services, we will be available to consult with the project team, respond to geotechnical issues that may arise during project development, and/or attend project meetings as required. We should also review the project plans as they near completion to ensure that the intent of our geotechnical recommendations has been sufficiently incorporated.

Phase 3 - Construction Observation and Testing
We should perform intermittent observation and testing of the geotechnical portions of the project to verify that our recommendations remain appropriate for actual conditions encountered and to form an opinion regarding the Contractor's compliance with the project plans and specifications.

Contractual Arrangements
Based on our understanding of the project and the scope of services described above, we propose the following fee arrangements:

Phase 1 - Geotechnical Investigation .... Fixed Fee, $17,900 Environmental Testing (if needed). .. $1,500
Phase 2 - Supplemental Consultation....... ... Time and Expense, Estimate, $1,500 Phase 3 - Construction Observation and Testing.. .......Time and Expense, Estimate, TBD** **Will provide a detailed construction observation and testing scope and budget proposal after project plans are finalized and a construction schedule is available.

and Scope
The additional funding of the CIA, D43CIARI0002, approximately $3,270,000 will be utilized for the design, purchase and construction of two hydrodynamic separators, Contech Continuous Deflection Separation (CDS) units. These units will be constructed at Bayview Ave.

Approximately 840 acres of land, of which 38 acres are from Caltrans Right of Way, 84 acres are from the City of Richmond, and 723 acres from the City of El Cerrito, will be treated by these units.

Caltrans has already advanced $591,866.57 that will be used for the purchase of the CDS units for the Bayview Ave project. This amendment will bridge the funding gap that remains to complete the design and construction of the project.

This CDS unit will screen, separate and trap debris, sediment, and oil and grease from stormwater runoff. The units have been rated as being effective at trapping 80% of sediment at either the 140- or 175-micron level depending on unit type. Thus, they will achieve load reductions of PCBs and Hg, beside trash.

This project was previously revised due to the construction and time constraints. However, now with additional funding and longer period for construction, the project will be able to succeed. There are three potential sites that have been reviewed for the Bayview Ave project. Design engineers will review the site(s) and determine the best location for the 4 City of Richmond

installation of the CDS units.

The proposed projects gear toward compliance of TMLs of trash, PCBs and Mercury, as set forth by in the San Francisco Bay Regional Water Resource Control Board. Ultimately, this project posts a watershed-based solution to reduce pollutant loadings, trash, and CBs and Mercury in sediments, from entering local watersheds and the San Francisco Bay from three different jurisdictions, City of Richmond, City of El Cerrito, and Caltrans, thus enhancing water quality for beneficial and recreational uses.

Introduction
On January 22, 2019, the City of Richmond (the City) and CALTRANS entered a Cooperative Implementation Agreement (the Agreement) to implement a water capture facility project, which consists of the construction of two full-trash capture devices (FTCDs), Contech CDS units, with the cost not to exceed $3 million. These devices were installed in the City on Regatta Boulevard (Meeker Ditch). The project completed under budget with the total cost of approximately $700,000.

On June 24, 2020, the City and CALTRANS amended the CIA to revise the scope of work to add another water capture facility project, consisting of two FTCDs on Bayview Avenue; utilizing the remaining funds of approximately $2.3 million to deliver additional trash load reduction from the City and CALTRANS right of ways. During the design phase of the project, based rocks were preliminary determined through the regional geologic map of the Richmond quadrangle published through the U.S. Geological Survey in 1980. The presence of base rock at the project location was later confirmed through boring activities. Field log noted base rocks was discovered at ten feet below ground surface (bgs), and refusal was encountered at 15 ft bgs at the Bayview project site (see Exhibit A). The removal of base rocks for the installation of the proposed FTCDs would have required added cost and time for the completion of the project. Furthermore, this activity could damage the foundation of the apartment complex located adjacent to the project site. Due to this geotechnical engineering constraints, it was deemed infeasible to complete this project within to the time frame and budget as prescribed in Amendment No. 1 of CIA No. D43CIARIC002. In order to avoid the scenario as described above in future partnership opportunities with CALTRANS, the City learns that it must perform an alternative analysis of multiple project sites to determine the most feasible project location for the installation of FTCD.

CIA No. D43CIARICO02
Amendment 3
This amended Scope Summary is to revisit the proposed water capture project at Bayview Avenue There were three locations that were examined regarding installation of the CDS units. Now that additional funding is available and time is not a factor, the Bayview Ave project can proceed.

Background
The City of Richmond is located in Contra Costa County, a county in the San Francisco Bay Region. The San Francisco Bay Region encompasses poltions of Alameda, Contra Costa, Marin, Napa, Santa Clara, San Francisco, San Mateo, Solano, and Sonoma Counties. One way that the San Francisco Regional Water Board protects water bodies within region is to develop Total Maximum Daily Loads (TMDLs), which are programs to restore water quality in water bodies impaired by pollutants such as Trash, PCBs and Mercury. To achieve the goals of the TMDLs, a reduction in the amount of inputs of the aforementioned pollutants to the San Francisco Bay (the Bay) is required.

In 2015, the San Francisco Regional Water Board reissued the stormwater Municipal Regional Permit 2.0 (MRP 2.0), a National Pollutant Discharge Elimination System (NPDES) permit that regulates discharges of stormwater runoff from MS4s. The MRP 2.0 includes provisions that implement the requirements in the Trash, PCBs, and Mercury TMDLs to reduce discharges of these pollutants in stormwater runoff to the San Francisco Bay. The reduction of these pollutants could be achieved through the implementations of FTCDs or green stormwater infrastructure (GS1), and programmatic approach such as the PCBs building demolition material controls.

The MRP requires compliance with TMDL requirements, specifically the San Francisco Bay Mercury TMDL (SFRWQCB, 2004, amended by SFR.WQCB, 2006) and the San Francisco PCB TMDL (SFRWQCB, 2008). Water quality objectives were established in each TMDI to protect beneficial uses of the impaired receiving water, mainly San Francisco Bay. PCB concentrations tend to be highest in sediments, thus typical bioaccumulation starts with bottom-feeding species and transfers along the flood chain, with the additional issue of biomagnification (increased concentrations in organisms higher up on the food chain) known to occur with PCBs. Mercury is also strongly associated with sediments and builds up through bioaccumulation and biomagnification. Methylmercury, the organic form of mercury, is of particular concern due to the toxicity and increased bioavailability to aquatic organisms. Overall, the consumption of some fish in San Francisco Bay can be a threat to human health given the elevated levels of PCBs and mercury in fish tissue. The legacy nature of the pollutants of concerns and lack of knowledge on dispersion and degradation processes contributed to the uncertainty in future conditions.

The PCB TMDL established two water quality objectives; a fish tissue target of 10 micrograms per kilogram (Hg/kg) and a sediment target of 1 pg/kg based on a food web model developed by the 6 City of Richmond
CIA No. D43CIARIC002
Amendment 3
San Francisco Estuary Institute (SFEI). To achieve these objectives, the total mass of PCBs in the active layer of the Bay must be reduced to 160 kilograms. Based on a mass budget model in the TMDL, external loads to the Bay must be reduced to IO kilograms per year to achieve the required reduction within 30 years. The waste load allocation (WLA) for urban stormwater is 2 kilograms per year, which must be achieved by 2030. Allocations were further broken down by County based on respective Bay-side populations in the year 2000, resulting in a WLA for Contra Costa County of 0.3 kilograms per year. The baseline PCB load from stormwater runoff was estimated at 20 kilograms per year, based on grab samples from Water Year (WY) 2005, resulting in a required load reduction of 10 kilograms per year (90% reduction).

The Mercury TMDL established two water quality objectives; a fish tissue target applying to 60- centimeter-long striped bass of 0.2 mg/kg (to protect consumption of fish) and a fish target applying to 3- 5- centimeter long fish of 0.03 mg/kg (to protect aquatic organisms and wildlife). To achieve these objectives, the suspended sediment mercury concentration must be reduced to 0.2 mg/kg diy sediment. The WLA for mercury in stormwater is 82 kilograms per year, of which Contra Costa County has a WLA of 11 kilograms per year. The baseline/existing load from urban stormwater was estimated at 160 kilograms per year, based on box models for sediment and mercury corresponding to WY 2003. The required load reduction from stormwater is therefore 78 kilograms per year. MRP Permittees are responsible for a load reduction of 62 kilograms per year, to be achieved by 2028, of which Contra Costa County is responsible for reducing 11.0 kilograms per year.

These reduction rates are required by the MRP as part of the process to achieve compliance with the Mercury and PCBs TMDLs for San Francisco Bay, Contra Costa County permittees are also required to reduce trash discharges to the Bay from municipal storm drain systems. This requirement began with the issuance of the first MRP in 2009, with a 40% reduction required in 2014. Under the current MRP term, no adverse impact on receiving waters from trash is required by 2022.

These reductions will largely be accomplished through the implementation of green infrastructure, including stormwater capture and use and/or infiltration to groundwater. Contra Costa County Clean Water Program developed a countywide Storm Water Resource Plan (SWRP) that focuses primarily on stormwater capture with a multi-benefit approach to overall water resources planning, including water quality. This plan is being followed by local Green Infrastructure Plans (G1 Plans) to meet MRP requirements. Development of the GI Plans will be a multi-year effort that includes preparation of a reasonable assurance analysis (RAA) to demonstrate that long-term GI Plan implementation by all MRP permittees will reduce PCB loads by three kilograms per year by 2040. 7 City of Richmond

Amendment 3
Proposed Project
The City proposes to relocate the project site back to Bayview Ave. Approximately 840 acres of land, of which 38 acres are from Caltrans Right of Way, 84 acres are from the City of Richmond, and 723 acres from the City of El Cerrito, will be treated by these units.

Caltrans has already advanced $591,866.57 that will be used for the purchase of the CDS units for the Bayview Ave project. This amendment will bridge the funding gap that remains to complete the design and construction of the project.

The proposed CDS unit for this project has been rated as being effective at trapping 80% of sediments at the 125-micron level. The reduction of PCBs and Mercury load in the Watershed can be as high as 1.15 mg/year/acre, and 12 mg/year/acre, respectively based on the land-use of the drainage area, 106.7 acres of old urban and 19.3 acres of old industrial The accounting method used for these reductions were documented in the BASMAA Source Control Load Reduction Accounting Report (2020). The loads reduced accounting methodology for FTCDs is the product of tributary area treated by large full trash capture device in acres, area weighted PCBs or mercury yield (mg/acre-year) and efficiency factor for FTCDs, which is assumed to be 20%. Small inlet FTCDs (i.e., United Storm CPS units) will be installed, where feasible, at the City's storm drain inlets to which stormwater from CALTRANS right of way discharge. A total of forty-two inlets are being evaluated for the feasibility of installing these units (Figure 5). The treatment shed areas, as well as PCBs and Mercury load reductions, will be calculated upon completion of feasibility evaluation for these small FTCDs. The installation of the small FTCDs will provide supplement treatment areas to address the reduced treatment areas as a result of the change in project location.

The revised project scope includes initial engineering and geotechnical assessments, detailed design, environmental compliance, local permit application (i.e., Encroachment permit) construction of a diversion structure and piping, construction of a CDS unit, excavation and construction of a high void underground storage/infiltration chamber, disposal of non- hazardous excavated soil, and reconstruction of disturbed portions of the site.

Hello Mary,
Thank you for sending the information and working with Caltrans on this project to install a trash capture device in the City of Richmond. This email gives the Water Board's acceptance of the CIA trash capture project proposal that you describe in your email below. Our approval of this cooperative project with Caltrans is conditioned on submittal of the following information by the City and/or Caltrans once project planning and design is finalized, and prior to construction:
• Map(s) delineating the area draining to the trash capture devices. Maps should identify the areas and trash generation rating of Caltrans and City ROW to be controlled for trash by the device. • GIS mapping and/or as-built plans showing the storm drain system draining to the trash capture device. Storm drain information should correspond with the drainage area maps. • Breakdown of Caltrans and City ROW acres controlled by the devices and the trash generation rating of those areas.
• Final design plans and calculations.
• Confirmation that the device meets the requirements of MRP Provision C.10 and is on the State Board list of approved trash capture devices.
• Final project agreements between Caltrans and the City. These should include identification of the party responsible for ongoing operation and maintenance of the device once installed. If operation/maintenance responsibilities are not described in the final agreements, provide this information in a separate document.

Thank you for identifying this opportunity to reduce trash discharges through the MS4 and working cooperatively with Caltrans to implement the project. This email serves as our conceptual approval of the project. Please let Derek Beauduy or me know if you have questions or if there are significant changes to the project as the planning and design process moves forward.

To Whom it May Concern:

As you may be aware, the City of Richmond and Caltrans are seeking a partnership to design and construct a large trash capture device in Richmond.

The proposed device is a debris/nutrient separating baffle box (DSBB/NSBB) that will treat 840 acres of land: 38 acres are Caltrans right-of-way, 84 acres are from the City of Richmond, and 723 acres are from the City of El Cerrito.

The attached map shows the drainage area.

This location was previously approved. However, due to physical constraints (utilities, ground impediments), the location was changed.

Now, with the additional funding, the device can be installed.

Project Scope:

These CDS units will screen, separate and trap debris, sediment, and oil and grease from stormwater runoff. The units have been rated as being effective at trapping 80% of sediment at either the 140 or 175 micron level depending on unit type. Thus, they will achieve load reductions of PCBs and Hg, beside trash.
