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.

Preparer Signature: Date: Print preparer name: Bryan Knapp 5/5/22~~ I , - 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.

Throughout this application you will find the pertinent information requested from the Fact Sheet Update Requirements, presented in the requested layout. Currently, REM Inc. has the TRITON PERF-FTC Device as an approved FTC Device as well as the Trition BFTG-FTC Insert and the Triton CPS-FTC on the approved list of devices. Again, we thank you for taking this time to review our application, and if any additional information is required or needed, please feel free to contact us when needed. Charles Fleischmann Vice President Revel Environmental Manufacturing, Inc. REM Inc. REM www.remfilrers.com Revel Environmental Manufacturing Inc. salcs@rcmfiltcrs.com (888) 526-4736 Lie. No. 8574 10 Northern California 960-8 Detroit Avenue Concord, California 94518 P: (925) 676-4736 F: (925) 676-8676 Southern California 2 110 South Grand Avenue Santa Ana, California 92705 P: (7 14) 557-2676 F: (7 14) 557-2679 2 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. 1B: Device Owner Contact and location information Charles Fleischmann Vice President 960 Detroit Ave. Suite B Concord, CA. 94518 (925) 676-4736 Charlie@remfilters.com 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 City of Concord: Dept. of Public Works City of Hayward: Dept. of Public Works Please feel free to ask for a more detailed reference list. 1H: Certification Clause I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

(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.
