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, "PRIORITY DEVELOPMENT PROJECT (PDP)
requirements or not considered a development project. This questionnaire will also determine if the project is subject to
TRASH CAPTURE 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
concurrentlv.

Description of Existing Site Topography and Drainage [How is storm water runoff conveyed from
the site? At a minimum, this description should answer (1) whether existing drainage
conveyance is natural or urban; (2) describe existing constructed storm water conveyance
systems, if applicable; and (3) is runoff from offsite conveyed through the site? if so, describe]:
The existing site can be categorized into one major drainage basin, with one primary discharge
location onto Cherry Avenue by sheet flow. Once on Cherry Avenue, runoff from the site travels
westerly until the runoff enters an existing storm drain curb inlet at the intersection of Cherry
Ave and Carlsbad Blvd. approximately 0.06 miles from the site. Runoff continues in the public
storm water facilities until ultimately reaching the Pacific Ocean.
Description of Proposed Site Development and Drainage Patterns
Project Description / Proposed Land Use and/or Activities:
The project scope includes the demolition of all existing onsite improvements and the
construction of three new single-family condominium units. The construction of the new
condominiums will include site grading, as well as drainage and utility improvements typical to
this type of multi-family residential development.
Does the project include grading and changes to site topography?
Yes
No
Description / Additional Information:
Project proposes to keep the existing natural grade as much as possible with minimal changes to
onsite topography. The grading consists of approximately 65 CY of cut and 35 CY of fill, resulting
in 30 CY of export. The site remedial grading requirements include removal and replacement of
4 to 5 feet. Resulting in 1,300 CY of remedial grading.
Does the project include changes to site drainage (e.g., installation of new storm water
conveyance systems)?
Yes
No
Description / Additional Information:
The proposed drainage system has a series of area drains throughout the site. Once runoff
reaches the area drains the runoff is routed through a buried storm drain system to a storm drain
catch basin and then released to the western portion of the property onto Cherry Ave by a
sidewalk underdrain outlet. Once discharging off the site runoff continues to drain west down
Cherry Avenue similar to the predevelopment condition.

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 grated inlet on site to collect and retain trash and stormwater runoff prior to
discharging onto Cherry Avenue. The trash capture BMPs were selected using the
rational method to determine the flowrate to the grate inlet and CASQA’s list of approved
trash capture BMPs. A single DMA was created for the grate inlet, 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 5(12) Perf-FTC was selected based on its treatment flow rate being
higher than the flowrate the grate inlet will receive. REM Triton Tdam 5(12) has apertures
less than 5mm ensuring capture of all particles 5mm in size or larger.
The one DMA will use REM Triton Tdam 5(12) Perf-FTC (5” x 12”) model with a treatment
flow of 0.40 cfs. DMA 1 will have a flow of 0.052 cfs reaching the Tdam 5(12).
The right of way is sloped at 2 percent away from the property line and towards the
adjacent street. All trash capture devices are located on site per the requirements of
Appendix J of the BMP design manual. This makes treatment and routing of runoff
generated by improvements in the right of way infeasible.

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.

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.

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
