[Insert City’s Storm Water Standard Questionnaire (Form E-34) here]
INSTRUCTIONS:
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, ‘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. PROJECT INFORMATION

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]:
1. The existing drainage conveyance is urban.
2. Within the developed area (Building 5781 & affiliates), the existing private storm
drains and inlets were constructed around the building 5781 to collect the runoff from
existing rooftop, parking spaces, and driveways. The storm drain system runs easterly
and convey the runoff to the public storm drain on College Boulevard.
Outside of the developed area (Building 5781 & affiliates), a roughly 10.5 ac
undeveloped open area is enclosed by the existing residential area to the northwest,
existing College Boulevard to the east, 5781 building and parking lots to the southwest.
The elevation drops quickly from 244 to 106. Several concrete brow ditches run parallel
to the contour northerly and discharge the slope side runoff to College Boulevard.
3. At southwest corner of the parcel boundary, a small offsite area (0.37ac) was
conveyed through the site. per the hydrology calculation, the Q100 flow for this site is
about 1.63cfs.

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.]
1. Identify the project boundary.
2. Per City of Carlsbad BMP Design Manual 4.2.2, All areas within the project’s property
boundary are subject trash capture including DMAs excluded from DCV calculations as
discussed in Section 5.2. If the city’s right-of-way adjacent to a self-mitigating area,
contains sufficient BMPs for trash capture per the city’s Trash Capture Program, the
self-mitigating area may be excluded from trash capture requirements subject to
discretion of the City Engineer.
3. The vegetated area within northeast portion of the project boundary are
self-mitigating and drains to the city's ROW. Sufficient Trash Capture BMPs for this area
are assumed to exist and thus are excluded from this SWQMP.
[Continued from previous page – This page is reserved for continuation of description of general
strategy for trash capture BMP implementation at the site.]
4. All existing/Proposed (where applicable) inlets/catch basins within the project
boundary are subject to Trash Capture Requirement.
5. Conduct site visit to identify the dimension, location, of all subjected inlets/catch
basins and whether the Trash Capture devices have been installed to any of these
inlets/catch basins. The site visit note is attached in next page.
6. Two existing inlets (CB1, CB2) are identified with the existing Capture Devices from
the site visit and were excluded from the Trash Capture BMP design in the first
submittal. However City requires all installed devices must be approved BMP and the
existing device cannot be identified as approved BMP due to the condition of the
devices. To ensure all devices are meeting the City requirement, these two existing
devices are also replaced by approved new BMPs.
7. Create DMA map to identify tributary area for each inlet, perform the Trash Capture
BMP sizing calculation (per City of Carlsbad BMP Design Manual, J.2.1) and Q100 year
peak flow calculation (per San Diego County Hydrology Manual).
8. Select Trash Capture BMP per the calculation and inlet/catch basin type.
9. Compile Trash Capture SWQMP report.

Intensity-Duration Design Chart -Template
Directions for Application:
(1) From precipitation maps determine 6 hr and 24 hr amounts
for the selected frequency. These maps are included in the
County Hydrology Manual (10, 50, and 100 yr maps included
in the Design and Procedure Manual).
(2) Adjust 6 hr precipitation (if necessary) so that it is within
the range of 45% to 65% of the 24 hr precipitation (not
applicaple to Desert).
(3) Plot 6 hr precipitation on the right side of the chart.
(4) Draw a line through the point parallel to the plotted lines.
(5) This line is the intensity-duration curve for the location
being analyzed.
Application Form:
(a) Selected frequency D ear
(b) p6 =D in., P24 = I l:6 = D %<2>

The soil surveys that comprise your AOI were mapped at 1:24,000.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map measurements.
Source of Map: Natural Resources Conservation ServiceWeb Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as of the version date(s) listed below.
Soil Survey Area: San Diego County Area, CaliforniaSurvey Area Data: Version 16, Sep 13, 2021
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Jan 23, 2020—Feb

The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

5.0 OPERATION AND MAINTENANCE INFORMATION
5.A. Inspection procedures and frequency considerations;
The Grate Inlet Filter Operation and Maintenance Manual and Curb Inlet Filter Operation and
Maintenance Manual are included with this submittal as Appendix D. These manuals include
detailed requirements and recommendations for operation and maintenance of the Inlet Filters
when used as Full Capture Trash Treatment Control Devices. A summary of requirements and
recommendations are listed below:
Maintenance Summary
• Clean filter basket. Typical service interval occurs once every 12 months (≈ 10 minute
service time).
• Replace optional hydrocarbon media booms. Typical replacement occurs once every 12
months (≈ 5 minute service time).
Notes:
• Maintenance cycles are dependent on site-specific pollutant loading.
• Maintenance operations should be planned to occur just prior to start of the rainy season
and at the termination of the rainy season for the most effective system operation.
30
Inspection Procedures
• Following the installation of a Grate Inlet Filter or Curb Inlet Filter, the unit will require
periodic and scheduled maintenance. Bio Clean® or a Bio Clean® approved contractor
can provide inspection and maintenance services.
• Inspection of the Inlet Filters should be quick and require no entry into the catch basins or
extensive use of equipment. The inspection should provide a general assessment of the
condition and operation of the Inlet Filter and an estimate as to the need or timing for
maintenance.
o The primary observation during inspection is the condition of the filter basket.
The filter basket should be in good, working condition and should be free from
obstructions or blockages. Accumulated trash levels should be documented and if
maximum capacity levels are exceeded, maintenance should occur.
5.B. Description of maintenance frequency considerations related to the
Device’s hydraulic capacity at various levels of trash capture volumes;
Standardized maintenance frequencies that are suitable for most sites are detailed in Section 5.A.
Maintenance frequency is very site specific depending on pollutant loading. Records from
inspections and prior maintenances should be periodically reviewed to assess the appropriateness
of the prescribed maintenance frequency. Table 3 and Table 4 in Section 3.c. list the hydraulic
capacities at various levels of trash capture volumes for the Grate Inlet and Curb Inlet Filters
respectively.
5.C. Maintenance procedures, including procedures to clean the trash
capture screen;
A full description of the maintenance procedures is located in the Grate Inlet Operation and
Maintenance Manual and Curb Inlet Operation and Maintenance Manual included with this
submittal as Appendix D. A summary of the key components of the procedures is listed below:
Maintenance Procedures
It is recommended that maintenance occur at least two days after the most recent rain event to
allow debris and sediments to dry out. Maintaining the Device while flows are still entering it
will increase the time and complexity required for maintenance. Cleaning of the Grate Inlet and
Curb Inlet Filter can be performed from finished surface without entry into catch basin utilizing a
vacuum truck. Some unique and custom configurations may create conditions that would require
entry for some or all of the maintenance procedures. Once all safety measures have been set up,
cleaning of the Grate Inlet and Curb Inlet Filter can proceed as follows:
• Remove all manhole cover or access hatches (traffic control and safety measures to be
completed prior).
31
• Using an extension on a vacuum truck, position the hose over the opened manhole, hatch
or grate opening. Insert the vacuum hose down into the filter basket and suck out trash,
foliage, and sediment. A pressure washer is recommended and will assist in spraying of
any debris stuck on the side or bottom of the filter basket. For the Curb Inlet filter, if the
filter basket is overly full, trash, sediment, and debris can accumulate inside the trough
and weir sections of the system. Once the filter basket is clean, power wash the weir and
trough pushing the debris into the filter basket (leave the vacuum hose in the filter basket
during this process so entering debris will be sucked out). Power wash off the trough,
weir, debris screen, and filter basket sides and bottom.
• Next, remove the optional hydrocarbon boom (if installed) that is attached to the inside of
the filter basket. They hydrocarbon boom is fastened to rails on two opposite sides of the
basket (vertical rails). Assess the color and condition of the boom using the color chart
guide. If replacement is required, install and fasten in place a new hydrocarbon boom.
Booms can be ordered directly from the manufacturer.
• The last step is to close up and replace the manhole or hatch and remove all traffic
control.
• All removed debris and pollutants shall be disposed of following local and state
requirements.
• Disposal requirements for recovered pollutants may vary depending on local guidelines.
In most areas, the sediment, once dewatered, can be disposed of in a sanitary landfill. It is
not anticipated that the sediment would be classified as hazardous waste.
• In the case of damaged components, replacement parts can be ordered from the
manufacturer.
Record Keeping Maintenance Procedures
• Following maintenance and/or inspection, the maintenance operator shall prepare a
maintenance/inspection record. The record shall include any maintenance activities
performed, amount and description of debris collected, and condition of the system and
its various filter mechanisms.
• The owner shall retain the maintenance/inspection record for a minimum of five years
from the date of maintenance. These records shall be made available to the governing
municipality for inspection upon request at any time.
5.D. Essential equipment and materials for proper maintenance activities;
The following equipment is helpful when conducting Grate Inlet Filter and Curb Inlet Filter
inspections and maintenance:
• Recording device (pen and paper form, voice recorder, iPad, etc.)
• Suitable clothing (appropriate footwear, gloves, hardhat, safety glasses, etc.)
• Traffic control equipment (cones, barricades, signage, flagging, etc.)
• Manhole hook or pry bar
32
•Flashlight
•Tape measure
•Measuring stick or sludge sampler
•Confined space entry equipment (if necessary)
•Vacuum truck
•Pressure washer
•Replacement absorbent booms
5.E. Description of the effects of deferred maintenance on device structural
integrity, performance, odors, etc.; and
Delayed or deferred maintenance can cause diminished pollutant removal, re-entrainment of
pollutants in catch basin and upstream hydraulic impacts, and impacts to water quality.
5.F. Repair Procedures for the Device’s structural and screening
components.
In the case that damage is done to any part of the Bio Clean® Grate Inlet and Curb Inlet Filter,
there are two approaches to repairing the damaged baskets. For minor damage, Bio Clean® can
send out a field welder to fix the basket on the spot. In cases where the damage is more
extensive, Bio Clean® recommends removing the damaged basket and replacing it with a new
one to ensure that all installed devices adhere to full capture requirements. In most cases
regarding damage, Bio Clean® recommends replacing the entire basket.
6.0 VECTOR CONTROL ACCESSIBILITY
6.A. The date the Device application was submitted for vector control
accessibility design verification via email to the Mosquito Vector Control
Association of California (MVCAC) (Trashtreatment@mvcac.org);

Grate Inlet Filter
1 | Page
OPERATION & MAINTENANCE
The Bio Clean Grate Inlet Filter is a stormwater device designed to remove high levels of trash,
debris, sediments and hydrocarbons. The filter is available in several configurations including trash
full capture, multi‐level screening, Kraken membrane filter and media filter variations. This manual
covers maintenance procedures of the trash full capture and multi‐level screening configurations. A
supplemental manual is available for the Kraken and media filter variations. This filter is made of
100% stainless steel and is available and various sizes and depths allowing it to fit in any grated
catch basin inlet. The filters heavy duty construction allows for cleaning with any vacuum truck. The
filet can also easily be cleaned by hand.
As with all stormwater BMPs, inspection and maintenance on the Grate Inlet Filter is necessary.
Stormwater regulations require BMPs be inspected and maintained to ensure they are operating as
designed to allow for effective pollutant removal and provide protection to receiving water bodies.
It is recommended that inspections be performed multiple times during the first year to assess site‐
specific loading conditions. This is recommended because pollutant loading can vary greatly from
site to site. Variables such as nearby soil erosion or construction sites, winter sanding of roads,
amount of daily traffic and land use can increase pollutant loading on the system. The first year of
inspections can be used to set inspection and maintenance intervals for subsequent years. Without
appropriate maintenance a BMP can exceed its storage capacity which can negatively affect its
continued performance in removing and retaining captured pollutants.

Inspection Equipment
Following is a list of equipment to allow for simple and effective inspection of the Grate Inlet Filter:
Bio Clean Environmental Inspection Form (contained within this manual).
Manhole hook or appropriate tools to remove access hatches and covers.
Appropriate traffic control signage and procedures.
Protective clothing and eye protection.
Note: entering a confined space requires appropriate safety and certification. It is generally
not required for routine inspections or maintenance of the system.
Inspection Steps
The core to any successful stormwater BMP maintenance program is routine inspections. The
inspection steps required on the Grate Inlet Filter are quick and easy. As mentioned above the first
year should be seen as the maintenance interval establishment phase. During the first year more
frequent inspections should occur in order to gather loading data and maintenance requirements
for that specific site. This information can be used to establish a base for long‐term inspection and
maintenance interval requirements.
The Grate Inlet Filter can be inspected though visual observation. All necessary pre‐inspection steps
must be carried out before inspection occurs, such as safety measures to protect the inspector and
nearby pedestrians from any dangers associated with an open grated inlet. Once the grate has been
safely removed the inspection process can proceed:
Prepare the inspection form by writing in the necessary information including project name,
location, date & time, unit number and other info (see inspection form).
Observe the filter with the grate removed.
Look for any out of the ordinary obstructions on the grate or in the filter and its bypass.
Write down any observations on the inspection form.
Through observation and/or digital photographs estimate the amount of trash, foliage and
sediment accumulated inside the filter basket. Record this information on the inspection
form.
Observe the condition and color of the hydrocarbon boom. Record this information on the
inspection form.
Finalize inspection report for analysis by the maintenance manager to determine if
maintenance is required.

Maintenance Indicators
Based upon observations made during inspection, maintenance of the system may be required
based on the following indicators:
Missing or damaged internal components.
Obstructions in the filter basket and its bypass.
Excessive accumulation of trash, foliage and sediment in the filter basket. Maintenance is
required when the basket is greater than half‐full.

Curb Inlet Filter
1 | Page
OPERATION & MAINTENANCE
The Bio Clean Curb Inlet Filter is a stormwater device designed to remove high levels of trash,
debris, sediments and hydrocarbons. The filter is available in several configurations including trash
full capture, multi‐level screening, Kraken membrane filter and media filter variations. This manual
covers maintenance procedures of the trash full capture and multi‐level screening configurations. A
supplemental manual is available for the Kraken and media filter variations. The innovative trough &
weir system is mounted along the curb face and directs incoming stormwater toward the filter
basket which is positioned “directly” under the manhole access opening regardless of its location in
the catch basin. This innovative design allows the filter to be cleaned from finish surface without
access into the catch basin, therefore drastically reducing maintenance time and eliminating
confined space entry. The filter has a lifting handle allowing for the filter to be removed easily
through the manhole. The weir also folds up to allow for unimpeded access into the basin for
routine maintenance or pipe jetting.
As with all stormwater BMPs, inspection and maintenance on the Curb Inlet Filter is necessary.
Stormwater regulations require BMPs be inspected and maintained to ensure they are operating as
designed to allow for effective pollutant removal and provide protection to receiving water bodies.
It is recommended that inspections be performed multiple times during the first year to assess site‐
specific loading conditions. This is recommended because pollutant loading can vary greatly from
