1. Introduction
In April 2015, the State Water Resources Control Board adopted the Trash Amendments, prioritizing stormwater trash control compliance for Municipal Separate Storm Sewer Systems (MS4s) throughout California, including the City of Fort Bragg (City). The Trash Amendments mandate that MS4s implement controls such as full capture systems, treatment devices, or institutional measures to prevent trash from impacting local receiving waters, including creeks, rivers, lakes, and the Pacific Ocean. In the North Coast Region, compliance is managed by the North Coast Regional Water Quality Control Board (NCRWQCB) through National Pollutant Discharge Elimination System (NPDES) permits. By December 2, 2030 the City is to achieve 100% trash capture.

This Trash Capture Feasibility Study summarizes tasks completed, identifies preferred and alternative trash capture sites, evaluates device options, and provides installation and maintenance cost estimates. This report serves as a tool to assist the City in implementing and funding projects to meet trash reduction requirements. The primary deliverables are one-page site summaries (Attachment 2) that present key information for prioritizing sites and design alternatives. The 10 project sites were evaluated, with several sites offering design alternatives.

The analysis includes trash reduction effectiveness and associated costs, based on the best available information at the time of the report. Cost estimates for installation and maintenance were developed through site-specific field assessments and information provided by the City.

Figure 1 shows the locations and drainage areas for the project site locations.

2. Full Trash Capture Devices

2.1 Capital Improvement Project Alternatives
There are a variety of devices available to meet the full capture trash reduction goal, including:
• Catch basin inlet filters/screens;
• Netting, screens, or hydrodynamic structures on a storm drain trunk line; and • End-of-pipe netting, screens, or hydrodynamic structures.

When selecting a device, it is important to consider the drainage area, hydraulic losses across the system when full, permitting requirements in open channels, device maintenance and access, property rights, and utility clearance. All of these factors should be weighed against the device, installation, and maintenance costs to ensure maximum capture volume per dollar spent. The current list of approved full trash capture devices is contained in Attachment 3.

2.1.1 High-Flow Devices (Large-Scale)
Large-scale devices provide a centralized location for construction and maintenance. The downside of large devices is that they capture flow from low trash generating areas resulting in the need to have a larger device to treat the additional runoff from areas with little trash reduction benefit.

Hydrodynamic separators (HDS) are widely
used in stormwater treatment. They are flowthrough structures with a settling or separation unit to remove sediments, floatables, and other
pollutants. They come in a wide range, and some
are as small as a standard manhole structure.

These inline systems can be cleaned using a
vacuum truck to pump out the trash, sediment,
and water that has collected in the bottom.

Engineering and installation costs can be quite
high, but the devices are long-lasting and can
capture trash from a considerable area.

Baffle boxes are concrete or fiberglass structures containing a series of sediment settling chambers separated by baffles. The primary function of baffle boxes is to remove sediment, suspended particles, and associated pollutants from stormwater. Trash is removed through the metal cage with 5mm mesh
located at the flow line of the
storm drain system. Baffle boxes
can be located either in-line or at
the end of storm pipes.

Cleaning of baffle boxes can be
accessed through a manhole or
hatch above ground with a vacuum
truck, with no confined spaced
entry required for servicing.

Screened systems are hinged for
easy access to collected sediments
in the baffle chambers below.

2.1.2 Inlet-Based Devices (Small-Scale)
Small scale devices include structures such as connector pipe screens and hanging baskets installed at storm drain inlets.

The connector pipe screen is a metal screen
assembly installed inside a catch basin, in front of
the outlet pipe, preventing debris from entering the
storm drain system. They are designed to be
permanently mounted to the catch basin or have a
quick disconnect feature to facilitate pipe jetting or
to prevent flooding should the basin drainage
system become clogged. These units are designed
to retain all trash and solids larger than 5 mm
inside the catch basin, and once in place, it also
retains large volumes of sediment. Therefore, the
trash capture and storage capacity of this product
are dependent upon the size of the catch basin where it is installed.

CONSULTING CIVIL ENGINEERS
The hanging basket is similar to the connector pipe
screen in that it is a separate unit that is installed into the storm drain system. Typically, installed in a catch basin, the hanging basket is an insert that keeps trash and large debris from entering the stormwater
system. A frame is inserted into the top of the catch
basin and is paired with a basket made with 5mm
opening perforations. The large screen openings allow
ample flow through and will not clog from sand and
sediment loading off streets and parking lots.

Inlet screens are desirable because they can be
installed relatively quickly and at a relatively low cost.

3. Cost Estimates and Maintenance Considerations

3.1 Unit Costs
The following assumptions were made in determining construction costs for each proposed device:
• High-flow devices are assumed to have a lifetime of 50-years; • Inlet-based devices are assumed to have a lifetime of 25-years; • Hydrodynamic separators and baffle boxes capital cost is estimated at $6,285 per drainage area acre based on recent bids;
• Inlet-based devices (i.e. inlet screens and hanging baskets) were estimated at $3,000 per device, based on recent quotes;
• 20% design added to total costs for high flow devices; • 50% design added to total costs for inlet-based devices; • 30% construction contingency added to total costs;
• Percentages based on the assumption that all projects are completed together into one bid package. A reduction of the number of high flow devices per bid document may increase percentages for design due to the increased cost of site investigations. It is recommended to use 35% design costs when doing multiple bid documents for high flow devices;
• Total Base Cost is presented in the 2025 construction year dollars and includes installation and construction needed to update drainage infrastructure to support trash capture device, and the device. It does not include maintenance or device replacement.

Table 3-1 lists the unit costs used to develop each of the site’s installation cost. Attachment 2 contains details of each site quantities and total cost.

Table 3-1: Unit Cost Assumptions
Item Total Base Cost
per Unit Unit
High-Flow
Devices $9,427 per acre of drainage area
Inlet-Based
Devices $5,400 each

3.2 Maintenance Considerations
Cleaning and maintenance costs are not included in the installation costs. They are provided in this section for reference only for City consideration. Maintenance of both high-flow and inletbased devices can be done by municipal staff or hired out to a cleaning contractor. Wages and vacuum truck unit cost were developed based on information provided by the City in 2024.

For cleaning, replacement, and maintenance, the following considerations should be taken:

Stormwater Trash Capture Feasibility Report
August 2025 10 Schaaf & Wheeler

CONSULTING CIVIL ENGINEERS
• High-flow devices are cleaned approximately two (2) times a year, requiring 4 hours of a team of two staff members at $67/hour, a vacuum truck at $119/hour, or approximately $2,000/device annually, which is increased to $3,000 to account for any clogging or fees to dump materials;
• Inlet-based devices are cleaned approximately two (2) times a year, requiring 2 hours of a team of two staff members at $67/hour, a vacuum truck at $119/hour, or $770/device annually.

3.3 Project Summary
Table 3-2 lists the project costs for each project site. Overall, it is estimated to cost $4M in capital for the City to achieve the 100% trash reduction goals by 2030. With an additional 12% construction management the City should anticipate approximately $4.6M to achieve the statewide trash amendment goals.

4. Hydraulic Considerations

4.1 Summary
This study did not evaluate the hydraulics of each site in detail. Instead, peak flows from the City’s Storm Drain Master Plan (SDMP) from 2004 were compared. In addition, the peak 1-hour, 1-year flows were summarized based on rational calculations to ensure proper sizing of the high flow devices. Table 4-1 summarizes the 10-year peak flows and treatment flow (1-year, 1-hour) at each site and compares to the existing pipe capacity. While some systems are noted as being undersized in the SDMP, there are notes that City staff have not experienced significant flooding.

At the Hazel and Alder sites, further research and study should be done to identify a capital improvement project to upsize the system prior to construction of a trash capture device because the existing capacity is lower than the treatment flow. Each site location has a recommended upsizing of pipe in the SDMP.

Alder, Kemppe, and Elm project sites include multiple proposed devices to capture total drainage area. Table 4-1 summarizes flows for the high-flow devices, since the small inlet-based devices are not flow-based for sizing considerations. During detailed design - each site location should have further hydraulic study during detailed design phase.

5. Permit Considerations

5.1 Overview
The trash capture project sites evaluated in this Report may be subject to review under the California Environmental Quality Act (CEQA), depending on the type, scale, and location of the proposed devices. CEQA review evaluates potential environmental impacts associated with project implementation, including construction, installation, operation, and maintenance activities.

The City processed a Coastal Development Permit Exemption and a CEQA Notice of Exemption in August 2024 for these trash capture locations. Because the proposed trash capture devices are located on the City’s existing storm drain infrastructure, additional permit requirements are not anticipated at this time.

6. Recommendations

6.1 Timeline and Coordination
The Trash Amendments, adopted by the State Water Resources Control Board (SWRCB) on April 7, 2015, and effective as of December 2, 2015, establish a statewide framework to eliminate trash discharges into California's surface waters. These provisions apply to all Phase I and II Municipal Separate Storm Sewer System (MS4) permittees, including the City of Fort Bragg, and mandate the implementation of trash control measures in areas designated as Priority Land Uses (PLUs).

Key milestones in the implementation timeline include:
• June 1, 2017: Issuance of Water Code Section 13383 Orders to MS4 permittees, requiring them to select a compliance track—either Track 1 (installation of full capture systems) or Track 2 (a combination of full capture systems, treatment controls, and institutional measures)
• December 2, 2018: Deadline for MS4 permittees to submit their chosen compliance approach and, if applicable, an implementation plan detailing how they will achieve full compliance
• 2020–2021: Reissuance of MS4 permits incorporating trash control implementation requirements and compliance milestones
• December 2, 2030: Final compliance deadline for all MS4 permittees to achieve full implementation of trash control measures as specified in their permits The City of Fort Bragg has selected Track 1 and as an MS4 permittee, is required to comply with these provisions by the December 2, 2030 deadline. Therefore, it is recommended that the City begin developing a funding plan and utilize the information included in this Report to identify which devices should be installed in the upcoming few years.

Additionally, it is recommended that City staff begin verbal communications with Regional Water Board to update staff on the steps that the City has taken to identify and install full trash capture systems. By communicating early with the Regional Water Board staff, the City will be best positioned to adjust its implementation program as needed based on the perspectives of the regulatory agency overseeing the implementation of the NPDES permit. Communications could include sharing the final version of this report and/or providing a presentation of the tasks completed to-date and the planned installation of full trash capture systems.

6.2 Prioritized Installation
Table 6-1 summarizes the project sites and associated cost implications, presenting the cost per Priority Land Use (PLU) acre treated for each design concept. Although there are 10 project sites, the table includes cost per acre values for both primary and alternative design options to aid City decision-making. Inlet-based devices generally provide the most cost-effective solution in terms of cost per acre of PLU treated, however, these devices are limited to smaller drainage areas.

6.3 Funding Opportunities
The City of Fort Bragg may coordinate with Caltrans to support funding and implementation of trash capture projects where state highway runoff contributes to local stormwater systems or affects Priority Land Uses. Caltrans, as an MS4 permittee under its own statewide stormwater permit, is also subject to the Trash Amendments and may enter into Cooperative Implementation Agreements (CIAs) to share compliance responsibilities and co-fund trash capture projects.

Alder, Elm, Chestnut all contain Caltrans right of way within their drainage area and may be eligible for this additional funding source.

Medium Sized Devices
The City has applied for grant funding for the GP Haul Road, Chestnut, and Kemppe projects. The projects are all mid sized devices and are shown to be cost effective in their dollar per PLU capture area treated.

Inlet Based Devices
The small, inlet based devices are all ranked top priority due to the smaller capital investment. It is recommended that these 4 devices are all lumped into one bid document to reduce the overall fee.

Alternatively, the City could consider working with a vendor who can install custom fit connector pipe screens on site. The County of Mendocino is also considering installing small, inlet based devices in several locations near Ukiah. The City could consider coordinating with the County to reduce the overall fee.

Large Devices
There are three devices that require significant capital investments – Alder, Elm, and Hazel. These device locations will require more time for design development and considerations on the system capacity and hydraulic impacts from full trash capture devices. The City should consider additional grant opportunities in the future.

6.4 Next Steps
Based on the information provide in this report, we recommend that the City:
• Identify funding for the detailed design and installations of the early installations and then identify how many installs can be achieved within the dedicated/available funding; • Consider working in house on the four small, inlet based devices • Identify other funding opportunities for the larger devices • Consider coordinating with Caltrans for funding support on large-scale devices that address Caltrans right-of-way (ROW);
The City should also begin setting aside funding for maintenance and operation needs and begin conducting staff training for device maintenance and operation. Jurisdictions without a vactor truck might need to obtain one, since this type of equipment will be needed to maintain large-scale (and possibly small-scale) devices. There are also private contractors who can be hired to do the maintenance in lieu of using City staff and equipment.

Site Specific Considerations:
• Site locations are within private property and easements should be investigated and might need to be acquired
• The parking lot is in poor shape and should be repaved as part of the project• Need to confirm the presence of 36-in pipe, which would bypass proposed location and require upstream installation within ROW
• Internal bypass flows should be confirmed with vendors O&M Summary: Devices will require vactor truck for maintenance 2 times per year. Comments/Notes: Access was not available to the 30-inch pipe during site visit. If there is a 36-inch and a 30-inch pipe leaving then an additional device will need to move upstream. The 30-inch pipe should be upsized to at least a 36-inch pipe or larger to ensure the trash capture device does not increase flooding upstream.

• Device should be located far enough from intersection so that cars can turn right onto Main Street during routine maintenance
• Internal bypass flows should be confirmed with vendors to ensure that the 10yr flow can be bypassed
• Street has heavy traffic
O&M Summary: Device will require vactor truck for maintenance 2 times per year.

Comments/Notes: Maintenance requested that device is located sufficient distance from the intersection so that traffic control is not an issue during maintenance.

System is overzied and might consider taking more flows that are currently routed towards Hazel Street. Updated flows would be needed and possibly increase the size of the device.

Proposed Device Type: Connector Pipe Screen (CPS) (See page 2 for Alternatives) Pipe Size: 18 inches Depth: 87 inches Grate: 36 inches x 24 inches Project Description: Construction of a connector pipe screen (CPS) installed on outlet pipe of existing catch basin, or into new catch basin structure downstream.

The CPS unit will be from the list of approved vendors by the Regional Water Quality Control Board (RWQCB). Once the full capture, 1-yr, 1hr design flow is exceeded, flows will weir over the top of the screen into the outlet pipe.

Site Specific Considerations:
• Catch basin is not located on the curb and gutter flow • Catch basin is located directly in front of private driveway • Downstream on the street is County jurisdiction
O&M Summary: Device will require vactor truck for maintenance 2 to 3 times per year. Considerations will need to be made with property owner about blocking driveway.

Comments/Notes: The entire street appears to have outdated catch basin grates.

There is an upstream driveway (111 Minnesota) that is unpaved and will likely send dirt and sediments that will be collected by the screen.

State Water Resources Control Board
Executive Director Designee Certification of Trash Full Capture Systems (Updated April 2025)
The State Water Resources Control Board Executive Director’s designee has received applications and certified the trash full capture systems (Systems) listed in the first table below, per the requirements of the Trash Provisions.1 Legacy Systems certified pursuant to the Trash Provisions are listed in the second table below, with a certification date of December 2, 2015 (the effective date of the Trash Provisions). Legacy Systems include those full capture systems that were listed in Appendix I of the Bay Area-wide Trash Capture Demonstration Project, Final Project Report (May 8, 2014). All Systems remain certified unless and until they are decertified by the State Water Board’s Executive Director or designee. The Trash Implementation Program webpage also includes a list of decertified Systems, including the reasons for decertification.

The tables below include the names of the applicants of the certified Systems. Applicants own the design of the Systems or were designated in writing by the owner of the design to pursue certification. Applicants may also manufacture or distribute the Systems or this may be done by third parties authorized by the applicant and specified in the application.

The tables also include the dates of certification and, if applicable, the date of any update or decertification. Systems are either identified by their application number or, for Legacy Systems, by an alpha numeric designation.

The Systems must be sized, manufactured, and installed according to the certified application to be compliant with the Trash Provisions. This also serves as certification of multi-benefit trash full capture systems listed separately in the document Certified Multi-Benefit Trash Full Capture Systems, first certified by the Executive Director’s designee on August 4, 2017. Multibenefit trash systems shall be designed in accordance with the criteria in that document. The document is available on the Trash Implementation Program webpage.

The applicant shall submit an amended application under the following circumstances:

1. If an applicant is proposing design feature revisions to a certified System 1 Amendment to the Water Quality Control Plan for Ocean Waters of California to Control Trash (Ocean Plan) and Part 1 Trash Provisions of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, And Estuaries of California adopted by the State Water Board located on the Statewide Water Quality Control Plans for Trash webpage at:
https://www.waterboards.ca.gov/water_issues/programs/trash_control/documentation.html

Page 2 of 9 ends

Executive Director Designee Certification of Trash Full Capture Systems (Updated April 2025)
(including revisions to or additions of filters, screens, configurations, bypass or other physical characteristics that affect the functionality of a certified System), the applicant must submit an amended application for recertification before use or sale of the updated System.

2. If the applicant is proposing minor revisions to the original certified application (i.e. routine revisions to the applicant’s contact information or to installation or maintenance instructions), the applicant may do so without delaying the use or sale of the certified System. Such minor revisions do not affect a System’s certification status. The Executive Director reserves the right to require re-certification of an amended application with such revisions if it is determined that the revisions are significant enough to warrant re-certification. In such an instance and upon notice from State Water Board staff, the applicant must wait for re-certification of the updated application prior to use or sale of the updated System.

Instructions for submitting an amended application are included in the Application Requirements for Trash Full Capture System Certification, which is available on the Trash Implementation Program webpage at:
https://www.waterboards.ca.gov/water_issues/programs/stormwater/trash_implementation.html Certified System applications are available on the California Stormwater Quality Association (CASQA) website (https://www.casqa.org/resources/water-qualitypriorities/trash/certified-trash-full-capture-systems-available-to-the-public).
