STORM WATER STANDARDS
QUESTIONNAIRE
E-34
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 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.

are concrete-lined all the way from the point of discharge to water storage reservoirs, lakes,
enclosed embayments, or the Pacific Ocean.
No, the project will discharge runoff directly to an area identified as appropriate for an
exemption by the WMAA for the watershed in which the project resides.
Description / Additional Information (to be provided if a 'No' answer has been selected above):
The area has been identified by the City as appropriate for an exemption by the optional WMAA
incorporated into the Water Quality Improvement Plan pursuant to provision B.3.b.(4) of the MS4
permit.
Critical Coarse Sediment Yield Areas*
*This Section only required if hydromodification management requirements apply
Based on the maps provided within the WMAA, do potential critical coarse sediment yield areas
exist within the project drainage boundaries?
Yes
No, No critical coarse sediment yield areas to be protected based on WMAA maps
If yes, have any of the optional analyses presented in Section 6.2 of the BMP Design Manual
been performed?
6.2.1 Verification of Geomorphic Landscape Units (GLUs) Onsite
6.2.2 Downstream Systems Sensitivity to Coarse Sediment
6.2.3 Optional Additional Analysis of Potential Critical Coarse Sediment Yield Areas Onsite
No optional analyses performed, the project will avoid critical coarse sediment yield areas
identified based on WMAA maps
If optional analyses were performed, what is the final result?
No critical coarse sediment yield areas to be protected based on verification of GLUs onsite
Critical coarse sediment yield areas exist but additional analysis has determined that protection is
not required. Documentation attached in Attachment 8 of the SWQMP.
Critical coarse sediment yield areas exist and require protection. The project will implement
management measures described in Sections 6.2.4 and 6.2.5 as applicable, and the areas are
identified on the SWQMP Exhibit.
Discussion / Additional Information:
Flow Control for Post-Project Runoff*
*This Section only required if hydromodification management requirements apply
List and describe point(s) of compliance (POCs) for flow control for hydromodification
management (see Section 6.3.1). For each POC, provide a POC identification name or number
correlating to the project's HMP Exhibit and a receiving channel identification name or number
correlating to the project's HMP Exhibit.
Not Applicable. However, the following would define these POCs.
POC 1 would be the outfall to Buena Vista Lagoon to the north.
POC 2 would be the discharge to Laguna Drive street curb and gutter.
Has a geomorphic assessment been performed for the receiving channel(s)?
NOT APPLICABLE, PROJECT IS EXEMPT FROM THESE REQUIREMENTS.
No, the low flow threshold is 0.1Q2 (default low flow threshold)
Yes, the result is the low flow threshold is 0.1Q2
Yes, the result is the low flow threshold is 0.3Q2
Yes, the result is the low flow threshold is 0.5Q2
If a geomorphic assessment has been performed, provide title, date, and preparer:
Discussion / Additional Information: (optional)
Other Site Requirements and Constraints
When applicable, list other site requirements or constraints that will influence storm water
management design, such as zoning requirements including setbacks and open space, or City
codes governing minimum street width, sidewalk construction, allowable pavement types, and
drainage requirements.
The most significant site requirement is bluff stability.
The soils report performed for the project recommends no drainage or infiltration to or near
bluff.
As such the proposed drainage pattern is a combination of storm drain lines to planter areas
on site which then drain to gutter
Optional Additional Information or Continuation of Previous Sections As Needed
This space provided for additional information or continuation of information from previous
sections as needed.
The project seeks to improve the existing condition of storm water drainage and protect the
bluff. Currently untreated run-off flows from buildings and parking lots to Laguna Drive.
Additional run-off also flows to open pervious areas of the site.
The new project will both diminish this deleterious condition by treating storm drain water,
appropriately locating infiltration locations and reduce the impervious areas of the site by 25%.
The project also seeks to reintroduce native habitat to the bluff both enhancing the Buena
Vista Lagoon ecology and in the process stabilizing. Outreach to Fish and Game has been
made and will be incorporated into the landscape design with an emphasis on correct
sourcing for native landscape materials.
These measures are part of an overall concept that has the redevelopment of the site actually
enhancing Buena Vista Lagoon and improving the environment in general.

PDP Structural BMPs
All PDPs must implement structural BMPs for storm water pollutant control (see Chapter 5 of
the BMP Design Manual). 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.
All of the Design Capture Volume is contained in a series of BMPs.
The BMPs include (3) Bioretention Basins and (1) Pervious Pavement System located within
the proposed project’s entrance drive aisle.

III. LOW IMPACT DEVELOPMENT AND SITE DESIGN BMPS
Low Impact Development (LID) and Site Design BMPs have been incorporated
into the project to minimize stormwater impacts. LID BMPs collectively minimize
directly connected impervious area and promote infiltration on the project site.
Site design BMPs are permanent measures and are similar to LID BMPs.
The LID and Site Design BMPs for the project which require maintenance are
identified along with their locations, including Drainage Management Areas
(DMAs), in Table 22 of the project WQMP. A LID Inspection form for the site is
provided in Attachment 4. In the event that a project use should change or
maintenance considerations may require the site to become amended, Table 22
should be referenced for original site constraints and design guidelines.

The location and type of each of the project’s stormwater facilities on site are
shown on the site map in Attachment 6.
The as-built drawings2, manufacturer’s data, cut-sheets, manuals, and specific
operation and maintenance requirements for each treatment control BMP shall
be provided in Attachment 7.
VII. INSPECTING STORMWATER BMPS
The quality of stormwater entering the waters of the U.S. or waters of the state
relies heavily on the proper operation and maintenance of permanent BMPs.
LID, source control, and treatment control stormwater BMPs must be periodically
inspected to ensure that they are functioning as designed. Inspections will
determine the appropriate maintenance that is required for the facility.
A. Inspection Procedures
All stormwater treatment BMPs are required to be inspected a minimum of once
per year. Inspections follow the inspection procedures found in the Inspection
and Maintenance Checklists provided in the City of Carlsbad’s BMP Design
Manual document or located on the City’s website
http://www.carlsbadca.gov/services/depts/landev/landdev.asp. The Inspection
and Maintenance Checklist(s) that is applicable to the site is provided in
Attachment 8.
B. Inspection Report
The person(s) conducting the inspection activities (Responsible BMP Party.
Employees reporting to Responsible BMP Party, or the Designated Emergency
Respondent) shall complete the appropriate inspection checklist for the specific
facility. All completed checklists are located in Attachment 8. All facilities are to
be inspected on an annual basis at a minimum. A copy of each inspection form
shall be kept by the property owner a minimum of 5 years.
Inspection Scoring
For each inspection item, a score is given to identify the urgency for any required
maintenance. The scoring is as follows:
0 = No deficiencies identified.
1 = Monitor – Although maintenance may not be required at this time,
a potential problem exists that will most likely need to be
addressed in the future. This can include items like minor erosion,
concrete cracks/spalling, or minor sediment accumulation. This
item should be revisited at the next inspection.
2 As-built drawings must be included after construction is complete.
CITY OF CARLSBAD
BMP OPERATIONS AND MAINTENANCE PLAN
570 Laguna Drive, Carlsbad, CA
BMP O&M PLAN 17
2 = Routine Maintenance Required – Some inspection items can be
addressed through the routine maintenance program. This can
include items like vegetation management or debris/trash removal.
3 = Immediate Repair Necessary – This item needs immediate
attention because failure is imminent or has already occurred.
This could include items such as structural failure of a feature
(outlet, weir, manhole, etc.), significant erosion, or significant
sediment accumulation. This score should be given to an item
that can significantly affect the function of the facility.
N/A = This is checked by an item that may not exist in a facility. Not all
facilities have all of the features identified on the form (outlet, weir,
manhole, etc.).
Overall Facility Rating
An overall rating is given for each facility inspected. The overall facility rating
should correspond with the highest score (0, 1, 2, 3) given to any feature on
the inspection form.
C. Verification of Inspection and Checklist Submittal
The Stormwater BMP Inspection and Maintenance Checklist (in Attachment 8)
provides a record of inspections and the need for maintenance activities at the
facility. Verification of the inspection of the stormwater facilities and the facility
inspection checklist(s) shall be provided to the City of Carlsbad Storm Water
Protection Program on an annual basis. The verification and the inspection
checklist(s) shall be reviewed and submitted by the property owner or
Responsible BMP Party, or the Duly Authorized Representative, per Table 1.
VIII. MAINTENANCE SCHEDULE FOR STORMWATER BMPS
A maintenance schedule for the stormwater source control and treatment control
BMPs on site is provided in Attachment 9. Attachment 9 includes schedules for
routine inspection and maintenance, annual inspection and maintenance, and
inspection and maintenance after major storm events.
A service agreement with any contractors hired to perform stormwater treatment
control BMP maintenance is also provided in Attachment 10.
IX. MAINTAINING STORMWATER BMPS
Stormwater BMPs must be properly maintained to ensure that they operate
correctly and provide the water quality treatment for which they were designed.
Routine maintenance performed on a frequently scheduled basis, can help avoid
CITY OF CARLSBAD
BMP OPERATIONS AND MAINTENANCE PLAN
570 Laguna Drive, Carlsbad, CA
BMP O&M PLAN 18
more costly rehabilitative maintenance that results when facilities are not
adequately maintained.
A. Maintenance Categories
Stormwater BMP maintenance programs are separated into three broad
categories of work: routine, restoration, and rehabilitation. The categories are
separated based upon the magnitude and type of the maintenance activities
performed. A description of each category follows:
Routine Work
This work includes items such as the removal of debris/material that may be
clogging the outlet structure well screens and trash racks. It also includes
activities such as road and parking lot sweeping, weed control, mosquito
treatment, and algae treatment. These activities normally will be performed
numerous times during the year. These items can be completed without any
prior correspondence with the City of Carlsbad Storm Water Protection
Program; however, inspection and maintenance forms shall be completed
with the information also being reported on the annual report forms and
submitted to the City.
Restoration Work
This work consists of a variety of isolated or small-scale maintenance and
work needed to address operational problems. Most of this work can be
completed by a small crew, with minor tools, and small equipment. These
items do not require prior correspondence with City of Carlsbad Storm Water
Protection Program. However, completed maintenance forms are required to
be submitted to City of Carlsbad Storm Water Protection Program with the
annual report forms.
Rehabilitation Work
This work consists of large-scale maintenance and major improvements
needed to address failures within the stormwater BMP. This work requires
consultation with the City and may require an engineering design with
construction plans to be prepared for review and approval by the City.
B. Maintenance Forms
The Stormwater BMP Inspection and Maintenance Form provides a record of
maintenance activities and includes general cost information to assist in
budgeting for future maintenance. Maintenance Forms for each facility type are
provided in Attachment 3. Maintenance Forms shall be completed by the
responsible BMP party. The form shall then be reviewed by the property owner
CITY OF CARLSBAD
BMP OPERATIONS AND MAINTENANCE PLAN
570 Laguna Drive, Carlsbad, CA
BMP O&M PLAN 19
or an authorized agent of the property owner and made available for review upon
inspection by the City of Carlsbad.
X. PREVENTATIVE MEASURES TO REDUCE MAINTENANCE COSTS
The most effective way to maintain a stormwater quality facility is to prevent
pollutants from entering the facility. Common pollutants include sediment, trash
& debris, chemicals, pet wastes, runoff from stored materials, illicit discharges
into the storm drainage system and many others. This maintenance program
includes measures to address these potential contaminants at the source and
save time and money in the long run. The maintenance program will consider
the following:
· Educate employees and patrons to be aware of how their actions affect
water quality and how they can help reduce maintenance costs.
· Keep properties, streets, gutters, and parking lots free of trash, debris,
and lawn clippings.
· Ensure the proper use, storage, and disposal of hazardous wastes and
chemicals. Promptly clean up spilled materials and dispose of properly.
· Plan landscape care to minimize and properly use chemicals and
pesticides.
· Sweep paved surfaces and put the sweepings back on the lawn.
· Be aware of automobiles leaking fluids. Use absorbents such as cat litter
to soak up drippings – dispose of properly.
· Encourage pet owners to clean up pet wastes.
· Re-vegetate disturbed and bare areas to maintain vegetative stabilization.
· Clean any private storm drainage system components, including inlets,
storm drains, and outfalls.
· Do not store materials outdoors (including landscaping materials) unless
properly protected from runoff.
XI. INSPECTION & MAINTENANCE – ANNUAL REPORTING
The tenant is responsible for providing verification that the stormwater treatment
control BMPs have been properly inspected and maintained unless otherwise
noted. Verification includes records of inspections and maintenance performed
on site. Any maintenance required will be identified and described.
Annual written verification of effective operation and maintenance of each
approved source and treatment control BMP by the responsible party is required
to be submitted to the City of Carlsbad Storm Water Protection Program prior to
each wet season (October 1) of each year. A standard annual reporting form is
provided in Attachment 11.
