Go to step 6, check the first box stating, "My project is subject to TRASH CAPTURE REQUIREMENTS ... " and the second or third box as determined in step 3. If you answered "no", Go to step 6, check the second or third box as determined in step 3. STEP& CHECK THE APPROPRIATE BOX(ES) AND COMPLETE APPLICANT INFORMATION 181 My project is subject to TRASH CAPTURE REQUIREMENTS and must comply with TRASH CAPTURE REQUIREMENTS of the BMP Manual. I understand I must prepare a Storm Water Quality Management Plan (SWQMP). 181 My project is a 'STANDARD PROJECT' OR EXEMPT from PDP and must only comply with 'STANDARD PROJECT' stormwater requirements of the BMP Manual. As part of these requirements, I will submit a "Standard Project Requirement Checklist Form E-36" and incorporate low impact development strategies throughout my project. If my project is subject to TRASH CAPTURE REQUIREMENTS, I will submit a TRASH CAPTURE Storm Water Quality Management Plan (TCSWQMP) per E-35A. D My project is a PDP and must comply with PDP stormwater requirements of the BMP Manual. I understand I must prepare a Storm Water Quality Management Plan (SWQMP) per E-35 template for submittal at time of application. Note: For projects that are close to meeting the PDP threshold, staff may require detailed impervious area calculations and exhibits to verify if 'STANDARD PROJECT' stormwater requirements apply. D My project is NOT a 'development project' and is not subject to the requirements of the BMP Manual.

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 two sub-basins and two primary discharge locations leaving the property. Drainage Basin EX-1 consists of the majority of the project site and primarily drains south to north discharging to Hope Avenue right-of-way by surface and sheet flow methods. Once in the Hope Avenue right-of-way, runoff leaving the site travels northwest to the Home Avenue intersection. Runoff then travels southwest to the Jefferson Street intersection and then Southeast along Jefferson Street until it is intercepted by a ribbon gutter on Grand Avenue and where an existing storm drain inlet is located. Drainage Basin Ex-2 is a small portion of the site where excess runoff drains onto Grand Avenue. Once in the Grand Avenue right-of-way, runoff travels southwest entering the existing storm drain inlet. Surface flows entering the storm drain inlet ultimately are conveyed to outlet in the Buena Vista Lagoon prior to entering the Pacific Ocean. After review of the site edge conditions, existing topography, and adjacent developments, it was determined that there is no additional offsite run on entering the site from the neighboring properties. Description of Proposed Site Development and Drainage Patterns Project Description / Proposed Land Use and/or Activities: This project scope includes the demolition of all existing onsite improvements and the construction of a new medical office building. The construction of the new building will include site grading, as well as drainage and utility improvements typical to this type of commercial development. Does the project include grading and changes to site topography? 0Yes □No Description/ Additional Information: The project proposed to precise grade the site along with some changes to onsite topography of the onsite grading. This consists of approximately 53 CY of cut and 16 CY of fill, resulting in 37 CY of export. 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 two proposed trash capture devices and area drains that will discharge via a sidewalk under drain on Hope Avenue and Grand Avenue. Once off the site, runoff flows to Grand Avenue to the existing curb inlet similar to predeveloped conditions.

Trash Capture BMP$ 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 ca_pture 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). The trash capture BMP was selected using the rational method to determine the flowrate to each grate inlet and CASQA's list of approved trash capture BMPs. Two DMA's were created for two inlets with the pipe screen connector inside, 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 1 c. 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 grate inlet will receive. REM Triton TDAM Filter has an aperture less than 5mm ensuring capture of all particles 5mm in size or larger. [Continue on next page as necessary.)
