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).
[Continue on next page as necessary.]
The trash capture BMP is certified to capture all debris greater than 5-mm in size and is sized for a 1-hr1-hr storm event, minimum.
The BMP selected complies with Certified Full Capture System Trash Treatment standards set forth by theCalifornia State Water Resources Control Board (Water Boards) and the California Stormwater QualityAssocation (CASQA).
The trash capture BMP is located at downstream locations, prior to discharging into the publicright-of-way. These locations provide treatment for the site to maximum extent feasible. Two DMAs werecreated, one for the inlet at the end of the concrete spill way and the other with in the 8" trench drain bothwith the REM TRITON TDAM-PERF-FTC. Runoff coefficients were calculated from a weighted averagedof the impervious and previous areas of the site, and the rainfall intensity was taken from Appendix J ofthe BMP design manual. The rational method calculations are included in attachment 1c. aftercalculating the flow rate being higher than then the flow rate the structures will receive. REM TRITONTDAM-PERF-FTC has an aperture less than 5mm ensuring capture of all particles 5mm in size of larger.
[Continued from previous page – This page is reserved for continuation of description of general
strategy for trash capture BMP implementation at the site.]
The trash capture BMP is certified to capture all debris greater than the 5-mm in size and is
sized for a 1-hr, 1-yr storm event, minimum.
The BMP selected complies with Certified Full Capture System Trash Treatment standards
set forth by the California State Water Resources Control Board and the California
Stormwater Quality Association (CASQA).

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.

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:

Section 2)
To determine the treatment rates, a commonly used equation was calculated. This is similar to the method used by the
County of Los Angeles Dept. of Public Works in a 2006 report on Full Capture Screen and Bypass Requirements. An
example of the equation is below:
C A 2gh Q MTFR =SF
d
Calculation for the model TR24SR-PERF-FTC Device:
0.60 * 2.08sf 2 * 32.2ft
s 2 * .66ftQMTFR=2
This equals: 3.32 CFS for the maximum treatment flow rate, while utilizing a safety factor of 2.

REM designed the TRITON -TDAM Filter Series to provide
a highly adaptable solution that allows the flexibility to
maximize the filter treatment flow rates and pollutant
capturing capacity in trench drain and shallow type
drains applications. The TRITON TDAM - PERF - FTC
Series uses Perforated Stainless Steel (PERF) Screen that
is designed to capture debris, trash and sediment while
sustaining very high treatment rates as a Full Trash
Capture System. Capturing 100% of particles at 5mm or
greater in size. TRITON -TDAM Filters can be sized to fit
most industry standard trench drains, parkway drains,
shallow structures, catch basins, etc. They are sized to
spec and scalable for all different lengths and
applications. Media strategy may also be optimized for
specific pollutant concerns.

3F: Alternative Configurations
There are no alternative configurations.
3G: Internal Bypass
All of the TRITON PERF-FTC Filters have built-in overflow bypass systems, this is breached only when the device has
become inundated with an excessive amount of debris and the device has reached its debris holding capacity, or during a
large storm event that exceeds the hydraulic capacity of the device. Essentially the device would need to be at 100%
capacity for the bypass level to be reached.
It is ultimately the responsibility of the engineer and/or deciding party to determine that the correct unit size is appropriate
for the selected basin and corresponding flow capacity.
3H: Previously Trapped Trash
With the design of the TRITON PERF-FTC, trash should only be re-introduced in a case where the device has reached
100% capacity during normal operating conditions. REM recommends that the devices are cleaned and maintained before
or at 50% capacity to ensure proper functionality.
3I: Calibration Feature
These devices do not contain any adjustable calibration features.

3K: Material Type
The design and construction of the TRITON PERF-FTC is comprised of the following materials: Type 304 stainless steel,
90% recycled content ABS plastic cap with UV Inhibitors or a fiberglass cap. The main housing and structural support
body is made up of an inner and outer wall of 13 GA. Type 304 stainless steel welded mesh with 2” X 2” square openings.
The filter housings are comprised of 100% recycled HMWPE (High Molecular Weight Polyethylene) and the PERF,
which is a type 304 Stainless-Steel, it is 22 GA. with 4.8mm openings which creates a total open area of 51%.
3L: Design Life
Under normal operations and with the impact of large storm events, the TRITON PERF-FTC has an estimated lifespan of
20+ years. Naturally occurring elements and mineral saturation do not have a resounding effect on either the stainless
steel, HMWPE, fiberglass or the ABS used in construction.

following instructions:
Step #1) If the Insert Filter has not been pre-cut, you will need to measure the Inside
dimensions of the catch basin walls to determine the flange size you will need. It should be ½ smaller than your I.D. For example, if the Inside Dimensions are 24"X24" you will need to cut your flanges to be 23.5"X23.5".
For round catch basins, measure the inside dimension then cut the filter flange ½ Dia., less, then the ID, then apply bulb gasket. Example: 24" Dia. ID, Cut Insert flange to
23.5" Dia.
INSTALLATION INSTRUCTIONS FOR THE
TRITON MODEL: INSERT – PERF - FTC
(Designed for Square and Round catch basins and other applications)
Step 1)If your TRITON Insert Filter has been pre-cut for you, simply remove the grate, clean any debris that is found on the ledge that the grate rests on.
Step 2)Place Filter Cartridge inside of unit, and line up with stainless steel screws on the bottom of the cartridge. Press down and twist 1/6th of a turn to lock cartridge in place, making sure filter is snug enough to prevent water from bypassing. Insert filter housing into catch basin as to where the flanges are resting on the grate & frame ledges. Place grate back on catch basin.
Step 3)If you received your unit un-cut, trim the flanges of the filter to be ½ smaller than the frame that surrounds the grate on the two support sides. Trim the other two sides that will not be supported to be ½ smaller than the clear frame opening, attach the supplied bulb gasket to the non-supported sides and set the Insert Filter into place. Place grate back on catch basin.
Note: Round units will be trimmed to ¼ smaller diameter than the size of the grate and will not use an attachable bulb gasket.
Support Bracket mountingDetermine where the support brackets will need to be placed in the catch basin for best support. To help you do this, place the filter into the catch basin and mark were the center of the support should be. Support brackets should be evenly
positioned for filter support. The top of the Insert Filter should rest 2" to 4" below the bottom of the grate. Using anchor bolts, attach the corner brackets to the inside walls of the catch basin using a hammer drill with ¼ bit. Make sure anchor bolts are as flush as possible to inside wall. Once the bracket are in place, place Insert Filter into
catch basin and place grate back on catch basin.

Step 1) Filter base plate flanges may need to be trimmed to fit into the throat of the catch basin. For example if the ID or inside
throat of the catch basin is 24"Dia., you will want to trim the flanges down to 23.5"Dia. (Taking just a ½ off the dia.) You will then attach the bulb gasket to the outer edge of base plate. This bulb gasket will help seal any gap between the base plate and th e
inside wall of the catch basin. The gasket is designed to give the base plate a snug fit when installed. Some base plates may be pre-trimmed and ready for installation.
Step 2) Depending upon the filters cartridge configuration the support brackets will vary with the height of each cartridge
height. For the 8" Tall Cartridges, the brackets should be mounted 10" or more below the grate seat. For 16" Tall Cartridges,
mounting brackets should be at least 19" or more below the grate seat (See attached Side View illustration below).
Step 3) Attach support brackets (Corner and slotted angle, if applicable) to the catch basin throat wall on four to eight sides equally spaced using anchor bolts. Attach slotted angle crossbars for larger catch basins (see Top View illustration below).
Step 4) Install filter base plate first without cartridge attached. Once a tight fit along the inside diameter of the catch basin is
obtained, attach the cartridge and replace grate.
Note: For catch basins that may have a tighter throat due to the frame and grate or other obstruction near the top, the filter base
plate may come in two sections that can be un-assembled, which will allow the base plate to be re-assembled below this area.
These parts will come assembled, so that you know how they should look like when installed.

INSTALLATION INSTRUCTIONS FOR THE
TRITON MODEL: CURB INLET – PERF - FTC
MADE INUSA
Step 1) While inside of the curb inlet catch
basin, starting from the left side wall to the right side wall of the curb inlet catch (while facing the
street) Place Curb Inlet Filter 2" to 3" below the start of the inside vertical wall. Mark the height
on the wall. Note: If the curb inlet is larger than 3.5', you will
be using additional section of filter. Joint Couplings will also be supplied to connect the
section together (See Figure #3) Each filter
section should come with two Cradle Brackets.
Step 2) Determine where the Cradle Brackets are to be placed horizontally along the inside
wall. The bracket should be placed in between the windows of the curb inlet filter. For a 2' Curb
Inlet section with only one window, the brackets will go on the two ends. (They should not block
any of the open areas of the windows. Having
the cradle brackets in position against the wall,
mark the location using the existing mounting
holes in the bracket as a template. These are where the holes are to be drilled to mount the
brackets. Drill two holes per bracket using ¼ masonry drill bits to install the concrete anchors.
Secure cradle brackets to wall using 7/16" socket driver.
Step 3) Once the two cradle brackets are
installed, place the Curb Inlet Filter into the
cradle brackets. Attach zip ties around cradle
brackets and filter.
Step 4) When adding adjacent sections,
duplicate steps #1, #2, and #3, installing from left to right making sure all sections are at the same
height. After installing the first two sections, place the black ABS Joint Coupling (Provided)
into both adjoining filter ends, then lock coupling into place by using set screws (pre-drilled into
coupling)

INSTALLATION INSTRUCTIONS FOR THE
TRITON MODEL: AREA DRAINS – PERF - FTC
Note: Area Drain Filters have been designed to be installed in a variety of
different applications. Most common are exit pipes that exit vertically through a catch basin or other receiving vessel. There are
two ways of securing Area Drain Filter into position.
Option A) If filter has been designed using a boot to connect to catch basin, it is simply
pushed into place like a compression fitting. Before doing so, clean the bottom of the
catch basin where the filter will be placed.Note: confirmation of exit pipe size is necessary so that the Area Drain Filter is
fitted with the correct boot size.
Option B) If filter has been designed using a tab mounting system, place Area Drain Filter directly over exit pipe and center.
Make sure to clean the bottom of the catch basin where the filter will be placed first.
Using a hammer drill with ¼ masonry drill bit, drill through existing mounting plates pre-drilled holes that are attached to both
the bottom and sides of the Area Drain Filter. Hammer in anchor bolt (Red Head s),
place washer over plate, then tighten down with nut using a 7/16" socket drive.

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.

4B: Description of installation limitations and non-standard installation procedures
One of the common limitations found in the field are catch basin that are too shallow, or the infrastructure is not
conducive for a standard Insert filter. We can filter many different types of configurations, but sometimes modifications or
custom units are needed to properly capture the target contaminant. When we come across unusual drains, our approach is
to always maximize the given catch basin configuration with the largest volume capturing ability. This may lead to a filter
that will need to be customized to fit. Typical modifications that may be needed are trimming the devices housings,
cutting down the size of the filter, or adding attachments like an extension of stainless steel or HMWPE depending on the
device and model type.
4C: Methods for diagnosing and correcting installation errors
A visual assessment can be done to determine if the device has not been installed correctly. If needed, the device can
simply be removed by lifting and removing the device or removing the anchor nuts and then removing the device. Proper
re-installation can take place at that point. All filters should be level and firmly in place. Filters are designed to hold a
large amount of trash and sediment, which requires the filters to be well supported. If there is any weakness in the support
of the filter, more support will of course be needed. There should also not be any gaps where water can bypass the system
during normal storm events. TRITON PERF – FTC Filters have been designed for their ease of installation. If anyone
does have installation problems, they may call our offices and we will be glad to help. 1 (888) 526-4736
Section 5: Operation and maintenance information
5A: Device inspection procedures and frequency considerations
Each device inspection can be done visually, remove the grate/manhole if needed and assess if the unit is damaged, at
what capacity, or experienced a bypass event. REM recommends that devices not on a standard maintenance schedule be
inspected 3 times per year or more if needed.
5B: Maintenance frequency considerations due to capacity at various volumes
REM recommends that devices be maintained 3 times per year, or as outlined by the governing body. It is recommended
that devices do not reach more than 50% capacity without a maintenance event. This frequency is dictated by the loading
capacity at each particular drain as well. If not properly maintained, devices will reach 100% capacity and begin the
bypass event for debris entering the catch basin. If filters are consistently above 50% full, REM recommends additional
maintenance intervals.
5C: Maintenance procedures
Secure area (Traffic and pedestrian controls, if needed). Pull grate and set aside. Remove (VAC) debris that has been
captured in system. Pressure washing may also be necessary in some cases to remove certain debris. After system has
been cleaned. Visually inspect filter for any damaged areas. Take a picture of the cleaned filter for your records. Fill out
report if used for the given catch basin. Replace grate. Remove all traffic control devices.
5D: Essential equipment and materials for proper maintenance
The maintenance for the TRITON PERF-FTC Filters is accomplished for the most part by using an industrial vacuum
truck due to the large capture capacity of the devices. Simply remove the grate and begin to remove the captured debris.
The device can be brushed or sprayed off if needed. Take note of the amount of debris collected along with the condition
of the device. Vacuum Truck, Grate Pick.
26
5E: Description of effects of deferred maintenance
Typical implications of deferred maintenance consist primarily of debris that will begin to bypass the device because it
has reached the full capacity of its limitations. If the device has been properly installed and supported, it should continue
to remain in the original placement from the initial installation.
5F: Repair procedures for device components
In the case that a particular component is damaged, it is advised to call our customer service department for repair or
replacement options. Please call (888) 526-4736 for repair or replacement issues.

6C: Letter of Verification from MVCAC
Revel Environmental Manufacturing, Inc 960 Detroit
Ave. Suite B
Concord, CA 94518
December 20, 2021
Dear Mr. Fleischmann,
Thank you for the submitting the Revel Environmental Manufacturing Inc. Triton PERF-FTC devices for review by the Mosquito and Vector Control Association of California pursuant to the SWRCB Trash Treatment Control Device Application Requirements. The Association has carefully reviewed the conceptual drawings for the Triton Insert PERF-FTC, Triton Top Hat PERF-FTC, Triton Curb Inlet, Triton TDam, and Triton Area Drain devices and verifies that provisions have been included in the designs that allow for full visual access to all areas for presence of standing water, and when necessary, allows for treatments of mosquitoes.
While this verification letter confirms that inspection and treatment for the purpose of minimizing mosquito production should be possible with the Revel Environmental Manufacturing Inc. Triton PERF-FTC devices as presented, it does not
affect the local mosquito control agency’s rights and remedies under the State Mosquito Abatement and Vector Control District Law. For example, if the installed device or the associated stormwater system infrastructure becomes a mosquito breeding source, it may be determined by a local mosquito control agency to be a public nuisance in accordance with California Health and Safety Code sections 2060-2067.
“Public nuisance” means any of the following: 1. Any property, excluding water, that has been artificially altered from its natural condition so that it now supports the development, attraction, or harborage of vectors. The presence of vectors in their developmental stages on a property is prima facie evidence that the property is a public nuisance. 2. Any water that is a breeding place for vectors. The presence of vectors in their developmental stages in the water is prima facie evidence that the water is a public nuisance. 3. Any activity that supports the development, attraction, or harborage of vectors, or that facilitates the introduction or spread of vectors. (Heal. & Saf. Code § 2002 (j).)
Declaration of a facility or property as a public nuisance may result in penalties as provided under the Health and Safety Code. Municipalities and the vendors they work with are encouraged to discuss the design, installation, and
maintenance of stormwater trash capture devices with their local mosquito control agency to reduce the potential for disease transmission and public nuisance associated with mosquito production. Sincerely,
Bob Achermann, MVCAC Executive Director
