To address post-development pollutants that may be generated from development projects, the city requires that new
development and significant redevelopment priority projects incorporate Permanent Storm Water Best Management
Practices (BMPs) into the project design per Carlsbad BMP Design Manual (BMP Manual). To view the BMP Manual, refer
to the Engineering Standards (Volume 5).
This questionnaire must be completed by the applicant in advance of submitting for a development application (subdivision,
discretionary permits and/or construction permits). The results of the questionnaire determine the level of storm water
standards that must be applied to a proposed development or redevelopment project. Depending on the outcome, your
project will either be subject to ‘STANDARD PROJECT’ requirements, ‘STANDARD PROJECT’ with TRASH CAPTURE
REQUIREMENTS, or be subject to ‘PRIORITY DEVELOPMENT PROJECT’ (PDP) requirements.
Your responses to the questionnaire represent an initial assessment of the proposed project conditions and impacts. City
staff has responsibility for making the final assessment after submission of the development application. If staff determines
that the questionnaire was incorrectly filled out and is subject to more stringent storm water standards than initially assessed
by you, this will result in the return of the development application as incomplete. In this case, please make the changes to
the questionnaire and resubmit to the city.
If you are unsure about the meaning of a question or need help in determining how to respond to one or more of the
questions, please seek assistance from Land Development Engineering staff.
A completed and signed questionnaire must be submitted with each development project application. Only one completed
and signed questionnaire is required when multiple development applications for the same project are submitted
concurrently.

SUMMARY OF TRASH CAPTURE BMPS
Trash Capture BMPs
All projects subject to trash capture requirements must implement trash capture BMPs (see
Chapter 4 of the BMP Design Manual). Selection of trash capture BMPs must be based on the
selection process described in Chapter 4.
Trash capture BMPs must be verified by the City at the completion of construction. This may
include requiring the project owner or project owner's representative to certify construction of
the trash capture BMPs (see Section 1.12 of the BMP Design Manual). Trash capture BMPs
must be maintained into perpetuity, and the City must confirm the maintenance (see Section 7
of the BMP Design Manual).
Use this form to provide narrative description of the general strategy for trash capture BMP
implementation at the project site in the box below. Then complete the trash capture BMP
summary information sheet for each trash capture BMP within the project (copy the BMP
summary information page as many times as needed to provide summary information for each
trash capture BMP).
Describe the general strategy for trash capture BMP implementation at the site. This information
must describe how the steps for selecting and designing trash capture BMPs presented in
Section 4.4 of the BMP Design Manual were followed, and the results (type of BMPs selected).
There is one brooks boxes w/ trash capture BMPs inside on site to collect and retain trash
in stormwater runoff prior to discharge onto State Street. The trash capture BMPs were
selected using the rational method to determine the flowrate to each grate inlet and
CASQA’s list of approved trash capture BMPs. One DMA’s was created for the brooks
boxes with trash capture BMP. There are also two DMA’s for de-minimis areas that are
less than 250 square feet. Runoff coefficients were calculated from a weighted average
of the impervious and pervious areas of the site, and the rainfall intensity was taken from
Appendix J of the BMP design manual. The rational method calculations are included in
attachment 1c. After calculating the flow rate, a REM Triton TDAM Filter was selected
based on its treatment flow rate being higher than then the flowrate the area drains will
receive. REM Triton TDAM Filter has apertures less than 5mm ensuring capture of all
particles 5mm in size or larger.

Section: 1 Cover Letter
1A: General Description
The TRITON PERF-FTC can be used as a stand-alone filtration device for capturing trash and debris inside of storm drain
catch basins. With its intended design, it can capture pollutants and debris as small as 5mm, meeting the requirement for
Full Trash Capture Devices. It does this, while still maintaining excellent flow rates due to its 51% open area. The
PERF-FTC device is intended to be installed in storm drain catch basins and is designed for lateral and surface flow
capturing applications depending upon configuration.

1C: Website Information
https://remfilters.com
1D: Manufacturing Location
All REM TRITON products are manufactured and designed in the state of California. REM Inc. has specialized in
providing storm drain filters/trash capture devices all over the country for 24+ years. *Address location listed above.
1E: Brief summary of field/testing results to demonstrate device functions
The TRITON PERF-FTC was successfully tested in capturing debris that is 5mm or greater in size, in a number of test
basins located in the greater San Francisco Bay Area and Southern California. Results and pictures from these tests can be
found in Section 8.
1F: Brief summary of limitations, and operational, sizing, and maintenance considerations
The TRITON PERF-FTC units are extremely adaptable and customizable in terms of mounting and attaching to the many
different types of catch basin configurations in the field today. Due to the many different product applications REM has
been able to offer, we have been very successful in filtering many catch basins that might otherwise be “passed up” on.
Each of these devices can be adjusted to fit custom layouts/structures. The proper unit is determined in part by the
outgoing pipe size, and then the structure size is taken into account. The approximate installation time takes between 10-
25 minutes, depending on the infrastructure layout. Maintenance on PERF-FTC devices typically involves an industrial
vacuum truck when the units are about 50% loaded or as required. Maintenance should be performed at least 3 times per
year or as needed.
3
This device is also able to house an absorbent media as well if ever required. No design modifications are needed, the
media element is simply placed between the inner and outer layers of the stainless-steel support housings while
maintaining its FTC requirement.
1G: Device installation locations
REM Inc. has been installing PERF-FTC devices in multiple California locations as well as national sales across the U.S.
as this has been an approved FTC device since 2018. Some installation areas of acknowledgement would be:
City of Antioch: Dept. of Public Works

INSTALLATION INSTRUCTIONS FOR THE
TRITON MODEL: TDAM – PERF - FTC
MADE INUSA
Step 1) TDAM s are to be placed every 3' to
4' from one another unless otherwise
specified, (See Figure #3). (TDAM s next to
exiting pipe of trench drain should be placed
4" to 6" from the exit), (See Figure #2)
Some trenches may have exit pipes at both
ends or in the middle of the trench. Use the
same instructions for each. For middle
exiting pipes, place one TDAM on each side
of exit pipe, 4" to 6" from exit pipe, (See
Figure #2).
Step 2) After deciding placement of
TDAM s, Clean any sediment or debris from
location. Slide TDAM into trench drain, until
it reaches the bottom of trench floor. Make
sure to place additional gasket in area s
where there are gaps or where water may
try to bypass the TDAM.
Step 3) Once in position, using a hammer
drill with ¼ masonry drill bit, drill through
existing mounting plate pre-drilled holes that
are attached to bottom of TDAM. Hammer
in anchor bolt (Red Head), place washer
over plate, then tighten down with nut.
Some units may require the use of side
mounting tabs as well.
Note: Some TDAM s may come with two
mounting plates per TDAM.
