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 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.

Therefore, it is expected that construction will not impact ater quality or environmentally sensitive areas. 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 3. Is runoff from offsite conveyed through the site? if so, describe Describe existing site drainage patterns: 1. Runoff within the project limits, flows from the northeast to the southwest via sheet flow and storm drain inlets. Therefore, the drainage conveyance is urban. 2. The site has two main storm drainage systems: the northwest storm drainage system collects runoff via drain inlets and sheet flow before discharging into an existing 18-inch storm drain that discharges into an existing storm drain cleanout on Blue Heron Place (Shuttle Road). The northeast storm drainage system collects runoff via drain inlets and sheet flow in an existing 12-inch storm drain before connecting to an 18-inch RCP storm drain pipe that discharges out to an existing storm drain cleanout on Blue Heron Place (Shuttle Road). Both 18-inch laterals ultimately discharge into the public storm drain system along Blue Heron Place. 3. There is no runoff from offsite that is conveyed through the site. 100-year Flow in existing 18-inch storm pipe: 16.0 cfs (per DWG 290-3), Project Description I Proposed Land Use and/or Activities: The project consists of two areas of redevelopment: The courtyard will consist of new hardscape, landscape, artificial turf areas, grasspave fire access drive and turnaround, water feature and new planter walls. The existing hardscape, landscape and grasspave fire access will be removed and demolished. The pool environment area will consist of hardscape, landscape, 3 new spas, splash pad, new pool, water slide, bathroom area, grasspave fire access and turnaround and retaining walls. The existing hardscape, landscape, family pool and spas will be removed and demolished. The land use will remain the same as the existing land use. List/describe proposed impervious features of the project (e.g., buildings, roadways, parking lots, courtyards, athletic courts, other impervious features): Proposed impervious surfaces include pedestrian hardscape, covered bathroom area, pools and spas. List/describe proposed pervious features of the project (e.g., landscape areas): Proposed pervious surfaces include landscape areas, artificial turf areas, grasspave fire access and turnaround.

Does the project include changes to site drainage (e.g., installation of new storm water conveyance systems)? ~ Yes D No Description / Additional Information: The project proposes two new storm drain systems: one in the courtyard and one in the pool environment. The new storm drain system in the courtyard will collect roof runoff from the existing roofs and new hardscape and landscape areas via area drain and ultimately being collected in an 8-inch storm drain pipe that will tie into the existing 12-inch storm drain with a proposed storm drain cleanout. The existing storm drain ultimately ties into the existing 18-inch storm at the southwest towards Blue Heron Place. The new storm drain system in the pool environment will collect runoff via area drain within the project limits and discharge into a storm drain cleanout that ties into the existing 18-inch storm drain at the southwest. Flows from the 18- inch storm drain will discharge into an existing cleanout. A proposed 18-inch will divert all the flows collected into a biofiltration basin located at the southwest corner of the site for water quality and hydromodification control management.

Selection of PDP structural BMPs for storm water pollutant control must be based on the selection process described in Chapter 5. PDPs subject to hydromodification management requirements must also implement structural BMPs for flow control for hydromodification management (see Chapter 6 of the BMP Design Manual). Both storm water pollutant control and flow control for hydromodification management can be achieved within the same structural BMP(s). PDP structural 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 structural BMPs (see Section 1.12 of the BMP Design Manual). PDP structural 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 structural BMP implementation at the project site in the box below. Then complete the PDP structural BMP summary information sheet for each structural BMP within the project (copy the BMP summary information page as many times as needed to provide summary information for each individual structural BMP . Describe the general strategy for structural BMP implementation at the site. This information must describe how the steps for selecting and designing storm water pollutant control BMPs presented in Section 5.1 of the BMP Design Manual were followed, and the results (type of BMPs selected). For projects requiring hydromodification flow control BMPs, indicate whether pollutant control and flow control BMPs are integrated together or separate. Because the project falls into the priority development project category, both pollutant control reatment and hydromodification requirements apply. Per geotechnical recommendations, full infiltration for this site is infeasible, how partial infiltration is feasible. See Attachment 1 d ompleted by the Geotech for Infiltration Feasibility Condition Worksheet. Harvest and reuse is deemed infeasible for this project site as mentioned in Form 1-7 in ttachment 1 c of this report. Following the BMP selection hierarchy, harvest, and reuse BMPs HU-1) and infiltration BMPs (INF-2) could not be used on this site. Therefore, the selected pollutant control BMP for this project are biofiltration (PR-1). The the minimum 3 percent sizing actor per Worksheet B.5-1 in Attachment 1 e of this report was used to size the biofiltration basin. BMP 1 (Biofiltration basin) is sized for pollutant and hydromodification control. BMP 1 will treat DMAs 1.1 , 1.2, 2.1, and 2.2 for pollutant control. DMAs 1.2 and 2.2 will be treated for Hydromodification Control. BMP 1 will have a catch basin acting as a flow control structure. The ow control structure be set 10-inches above the finish grade of the basin to allow for hydromodification control. A 6-inch perforated underdrain will be set 3" above the bottom of the ravel storage layer and will connect to the catch basin flow control structure. The underdrain utlet will be fitted with a 1.67-inch diameter orifice to mitigate 10 percent of the 2-year storm for hydromodification control. ee biofiltration basin detail for BMP 1 in Attachment 2a Hydromodification Management Exhibit Hydromodification basin was sized using the San Diego Hydrology Model 3.1 (SDMH 3.1 ). See ttachment 2d off this report for SOHM inputs and results.

PURPOSE OF THE BIOFILTRATION BMP MAINTENANCE MANUAL The purpose of this manual is to provide maintenance instructions for the Biofiltration BMPs located within Park Hyatt Aviara. The Biofiltration basin is a pollution control device designed to treat urban runoff before it enters into the storm drain systems located on the project site. Regular maintenance will help to ensure that the biofiltration functions as it has been designed. This manual will serve as a reference guide and filed manual to assist the property owner with: • An overview of the Biofiltration BMP and how it functions • A description of the location of the Biofiltration BMP • An understanding of the procedures required to effectively maintain the Biofiltration BMP on a regular basis • Reproducible copies of the forms, logs and guidance sheets necessary for recording maintenance activities associated with the Biofiltration BMP. 2. GENERAL DESCRIPTION AND FUNCTION OF THE BIOFILTRATION BMP The Biofiltration BMP is a structure filled with gravel soil and vegetation that drain to an underdrain which connects to the storm drain system. These systems also have an overflow structure to prevent high flows from leaving the planter area. From the top of the curb or concrete step-off to the bottom, the porous materials consist of BMP l: • 3" of well-aged shredded mulch • 18" of Biofiltration Soil Media (BSM) • 4" Washed Pea Gravel Filter Course Layer • 18" Open Graded Sub-Base Course rounded #57 Stone, 40% Voids A 611 diameter perforated pvc underdrain will be installed 3" from the bottom of the open graded sub-base. This pipe connects to the storm drain. Pollution is mitigated through infiltration of runoff into the porous materials within the planter and ultimately through infiltration through the biofiltration soil media and stone layers. 3. MAINTENANCE RESPONSIBILITY XRS Carlsbad TRS. wi ll be responsible for Site Design, Source Control and Treatment Control BMPs and is ultimately responsible for maintaining the Biofiltration BMP. The goal in maintaining the planter is to ensure that Infiltration is occurring. Regular inspection and replacement of materials within the planter once it becomes ineffective in performing as designed are the major components in the maintenance program. In order to achieve this, the following general procedures shall be followed: • Qualified maintenance personnel should periodically inspect the planter at least twice a year. The first inspection should happen prior to August l and the subsequent inspection should happen during the period between February I and March 31. • If a problem is identified, it should be rectified as soon as possible to ensure that the trench functions as designed, STORM WATER QUALITY MANAGEMENT PLAN Park Hyatt Aviara ATTACHMENT 3 -BMP MAINTENANCE PLAN -BIOFILTRATION BASIN • Regular removal of trash and debris should occur as needed. Trash and debris, visible along the surface of the trench shall be promptly removed. Detailed maintenance procedures ore outlined 5. 4. MAINTENANCE INDICATORS AND ACTIVITIES Functional Maintenance: Regular functional maintenance is required to ensure that the Biofiltrotion BMP performs in an effective manner. Functional maintenance consists of both preventative and corrective activities. Logs and guidance sheets ore contained herein to use in recording vital information while performing operation Inspection and other infiltration trench maintenance activities. Maintenance records shall be maintained by the property owner for a minimum of five years. The proper use and subsequent storage of these records will assure the City of Carlsbad that the Biofiltration BMP is functioning as designed. Preventative Maintenance: Preventative maintenance shall be performed on a regular basis. Checklists are included herein to track and record preventative maintenance activities. These activities include trash and debris removal and sediment management, Trash and debris removal shall be performed to ensure that runoff hos adequate surface area to infiltrate through the various layers that comprise the cross section of the trench. Sediment management will occur when testing Indicates that the Infiltration rote hos diminished below the stated acceptable rote. Corrective Maintenance: Corrective maintenance will be required on an emergency or non-routine basis to correct problems and restore the intended operation and safe function of the Biofiltration BMP. STORM WATER QUALITY MANAGEMENT PLAN Pork Hyatt Avioro ATTACHMENT 3 -BMP MAINTENANCE PLAN -BIOFILTRATION BASIN Biofiltration BMP Maintenance • Inspect a minimum of once per year, before the rainy season, and after large storm events or more frequently as needed. • Clean the planter when the loss of infiltrative capacity is observed. When the standing water is present for a period of time in excess of 72 hours, removal of sediment may be necessary. • Control mosquitoes as necessary. • Remove litter and debris from surface as required. Maintenance Indicators: Maintenance Indicators are signs or triggers that indicate that maintenance personnel need to check the Biofiltration BMP for maintenance needs. The most common triggers include warnings or accounts of standing water and sediment accumulation. Inspection and Maintenance Checklist in Section 5 below shows conditions and criteria that trigger the need for some specific routine infiltration trench maintenance activities. Emergencies may occasionally arise that would require a more urgent, critical response. Sediment Management: The types of storm water pollutants that accumulate in sediment varies, but may include contaminants such as heavy metals, petroleum hydrocarbons, and other organic compounds such as pesticides or solvents. When the sediment has clogged the Biofiltration BMP, remove and properly dispose of Sediment. Regrade if necessary. Sediment Disposal: Several methods for disposal are available depending on the concentration of toxins in the waste. Methods can range from recycling the material, to depositing the sediment into appropriate landfills. At the time of disposal, if the wastes are deemed to be unfit for disposal in a municipal landfill, a full and comprehensive testing program should be run by a qualified person to test for all the constituents outlined under California code of Regulations (CCR) Title 22. Title 22 list concentrations of certain chemicals and their soluble threshold limit concentrations (STLC's) and their total threshold limit concentrations (TTLC's). Chemicals that exceed the allowable concentrations are considered hazardous wastes and must be removed from the sediment. 5. INSPECTION AND MAINTENANCE CHECKLIST See following page.
