I have read and understand that the City Engineer has adopted minimum requirements for managing urban runoff, including storm water, from land development activities, as described in the BMP Design Manual. I certify that this SWQMP has been completed to the best of my ability and accurately reflects the project being proposed and the applicable source control and site design BMPs proposed to minimize the potentially negative impacts of this project's land development activities on water quality.I understand and acknowledge that the plan check review of this SWQMP by the City Engineer is confined to a review and does not relieve me, as the Engineer in Responsible Charge of design of storm water BMPs for this project, of my responsibilities for project design. ________________________________________________________ Engineer of Work's Signature, PE Number & Expiration Date ________________________________________________________ Print Name ________________________________________________________ Company ____________________________ Date Samuel Michael Bellomio Ware Malcomb 90818 12/31/2023 11/10/2022 Active Motif Generator CD2022-0027 PROJECT VICINITY MAP PROJECT SITE N EB NOT TO SCALE STORM WATER STANDARDS QUESTIONNAIRE E-34 Development Services Land Development Engineering 1635FaradayAvenue 442-339-2750 www.carlsbadca.gov 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 concurrently.

Preparer Signature: Date: Print preparer name: Samuel Bellomio 11/10/2022 ,,,,,,,, -,~ 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). [Continue on next page as necessary.] The proposed improvements will not add additional storm drain inlets. The project will propose to retrofit the existing grated inlet structures located throughout the property with Bioclean Grate Inlet Filters (selected from the "Certified Capture System List of Trash Treatment Control Devices Updated September 2021"). The trash capture BMPs were sized by calculating the site-specific one-year, one-hour flow rate and comparing it to the trash capture device treatment flow rate (See Attachment 1c for calculations). The selected trash capture BMP was selected to meet the requirements set forth in the City of Carlsbad BMP Design Manual revised September 1, 2021.

Contech is your partner in stormwater management solutions Bio Clean® Catch Basin Inlet Filter Configurations Bio Clean® Catch Basin Inlet Filter Advantages Removing trash and sediment to protect our waterways ... Our nation has some of the world’s most beautiful beaches and waterways. Unfortunately, trash such as cigarette butts, food packaging, cans and bottles, and plastic waste makes its way into streams, creeks, rivers, and the ocean, as rain events wash them into gutters and storm drains. Bio Clean Catch Basin Filters provide the first defense against trash and other pollutants entering your stormwater steam by providing 100% trash capture at the source, preventing system clogging and improving downstream water quality. Bio Clean Catch Basin Inlet Filters offer superior durability and customization ... 1-year warranty Long-lasting, stainless-steel construction Designed for a wide range of sizes to fit most curb and grate inlets High-flows bypass prevents scouring of previously captured trash and debris Installed and maintained in minutes Testing Highlight: California Water Board 100% of Trash Full Trash Capture Testing Highlight: Over 1,000 LBS of load capacity Standard Sediment Filter Testing Highlight: Third Party Testing 85% of TSS & 72% of TP Kraken® Membrane Filtration Designed for maximized flow rates while meeting trash full capture requirements by the State of California Water Board. Our filters provide easy access for maintenance from the surface without having to enter the catch basin. Maintenance service takes about 15 minutes and requires no confined space entry. Each Bio Clean Catch Basin Inlet Filter is designed to be insertable and the expandable trough system is designed to convey water quality design flows through the filter basket while allowing peak flows to bypass over the trough without resuspending captured pollutants. The modular design of the trough system makes it adaptable to any size* or type of curb inlet catch basin. *Some depth restrictions may apply. Bypass to prevent backflow during the largest storm events. Bio Clean® Catch Basin Inlet Filter Applications Bio Clean Catch Basin Inlet Filters have been successfully used on numerous new construction and retrofit projects. The system’s superior durability and customization make it ideal for a wide range of stormwater applications. Each filter fits within a shallow catch basin, giving them the ability to integrate with versatile curb inlet trough systems. Applications include: Parking Lot Curb Inlets Parking Lot Grate Inlets Roadway Curb Inlets Roadway Grate Inlets Bioswale Bypass Structures Stormwater Pretreatment Bypass Flow Path Treatment Flow Path Curb Opening Trough System Non-Clogging Screen Outflow Pipe Bypass Weir Bottom Screen Hydrocarbon Boom Rail Hydrocarbon Boom Captures 100% of trash ENGINEERED SOLUTIONS Full Trash Capture Full Capture Sizing Full Capture Removes 100% of Trash ... The Full Trash Capture catch basin inlet filter is California Full Capture approved and allows for a higher flow of water, making it more applicable for demanding applications. The screen has a specialized design that efficiently captures all trash, but also makes cleaning more efficient while maintaining its ability to meet demanding flow requirements.
