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.

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).
Per Section 4.4 of the City of Carlsbad BMP Design Manual (Design Manual), all areas within the project’s property boundary are subject to trash capture due to the classification of the site within a Priority Land Use (PLU).
The trash capture BMPs must be located to fulfill the requirements of Design Manual Appendix J.2.3., such that stormwater runoff from the subject property undergoes trash capture prior to discharge to storm drain.
An assessment of the site drainage system as-builts was conducted and trash capture-specific Drainage Management Areas were delineated. Trash capture points were identified as necessary for meeting the design manual requirement.
These locations were sized in accordance with Design Manual Appendix J.2.1. Flow rates were calculated per the Rational Method for the 1-yr, 1-hr design flow rate and 100 year peak flow rate. The storm intensity was chosen from the Oceanside Pumping Plant data as recommended in the Design Manual.
Inlet and catch basin dimensions were referenced from the Lincoln Northpointe Grading and Erosion Control Plan.

OVERVIEW
The Bio Cle.an Grate Inlet Filt·er for catch basins is a filter system that is designed to capture fine to coarse
sediments, floatable trash, debris, and hydrocarbons conveyed in stormwater runoff.
The filter system is available in three different model tyPes: Full Capture, Multi-level Screening (MLS), and
the revolutionary Kraken Type media filter model.
Constructed of 100% high-grade stainless steel, it is built to last longer than any other lilter brand. The non-
clogging screens provide higher levels of filtration and waler flow. The filter is equipped with unimpeded high
flow bypass lo prevent bad:.flow during the largest storm events. The filter is also equipped with a floating
hydrocarbon boom mounted to rails allowing it lo flow up and down with the water level lo provide constant
oil and grease removal.
The filter is designed for grated inlets of any size and
depth. Each filter c.an be custom built to meet specific
project needs. Screen size and media type can be
modified to remove specific pollut;mts.

ATTACHMENT 2 Trash Capture BMP Maintenance Information
Use this checklist to ensure the required information has been included in the Structural BMP Maintenance Information Attachment: Preliminary Design/Planning/CEQA level submittal: Attachment 2 must identify: Typical maintenance indicators and actions for proposed trash capture BMP(s) based on Section 7.7 of the BMP Design Manual
Final Design level submittal:
Attachment 2 must identify:
Specific maintenance indicators and actions for proposed trash capture BMP(s). This shall be based on Section 7.7 of the BMP Design Manual and enhanced to reflect actual proposed components of the trash capture BMP(s)
How to access the trash capture BMP(s) to inspect and perform maintenance
Features that are provided to facilitate inspection (e.g., observation ports, cleanouts, silt posts, or other features that allow the inspector to view necessary components of the trash capture BMP and compare to maintenance thresholds)
Manufacturer and part number for proprietary parts of trash capture BMP(s) when applicable
Maintenance thresholds for BMPs subject to siltation or heavy trash (e.g., silt level posts or other markings shall be included in all BMP components that will trap and store sediment, trash, and/or debris, so that the inspector may determine how full the BMP is, and the maintenance personnel may determine where the bottom of the BMP is . If required, posts or other markings shall be indicated and described on structural BMP plans.)
Recommended equipment to perform maintenance
When applicable, necessary special training or certification requirements for inspection and maintenance personnel such as confined space entry or hazardous waste management

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.

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 Equipment
It is recommended that a vacuum truck be utilized to minimize the time required to maintain the
Curb Inlet Filter, though it can easily cleaned by hand:
Bio Clean Environmental Maintenance Form (contained in O&M Manual).
Manhole hook or appropriate tools to remove the grate.
Appropriate safety 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 maintenance of the system. Small or large vacuum truck (with
pressure washer attachment preferred).
Maintenance Procedures
It is recommended that maintenance occurs at least two days after the most recent rain event to
allow debris and sediments to dry out. Maintaining the system while flows are still entering it will
increase the time and complexity required for maintenance. Cleaning of the Grate Inlet Filter can be
performed utilizing a vacuum truck. Once all safety measures have been set up cleaning of the
Grate Inlet Filter can proceed as followed:

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 multi-level screening configuration. A supplemental manual
is available for the trash full capture configuration, as well as the Kraken and media filter variations.
This filter is made of 100% stainless steel and is available in various sizes and depths allowing it to fit
in any grated catch basin inlet. The filter’s heavy duty construction allows for cleaning with any
vacuum truck. The filter 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.

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
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

appropriate maintenance a BMP can exceed its storage capacity which can negatively affect its
continued performance in removing and retaining captured pollutants.

and custom configurations may create conditions which would require entry for some or all of the
maintenance procedures. Once all safety measures have been set up cleaning of the Curb Inlet
Filter can proceed as followed:
Remove all manhole cover or access hatches (traffic control and safety measures to be
completed prior).
Using an extension on a vacuum truck position the hose over the opened manhole or hatch
opening. Insert the vacuum hose down into the filter basket and suck out trash, foliage and
sediment. A pressure wash is recommended and will assist in spraying of any debris stuck on
the side or bottom of the filter basket. If the filter basket is full, trash, sediment, and debris
will accumulate inside the trough and weir sections of the system. Once the filter basket is
clean power wash the weir and trough pushing these debris into the filter basket (leave the
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 hydrocarbon boom that is attached to the inside of the filter basket. The
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 following information in the next
