Project Description
The 330 Chinquapin project consists of demolition of one existing building at 330
Chinquapin Avenue and creation of a new 7 unit subdivision. There is an existing
residential driveway and asphalt parking lot adjoining the existing building at 330
Chinquapin Avenue. The driveway will remain in approximately the same horizontal
location, but will extend further north to service the three new structures in the south end
of the lot and the multifamily dwelling unit at the north end of the lot. The driveway and
multi-use drainage facilities that will be built as part of this project will be maintained as
part of the new multi-family subdivision, wherein all future maintenance requirements will
be the responsibility of each land owner in perpetuity.

j tNSTRUCTIONS:
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.

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; and
(3) is runoff from offsite conveyed through the site? if so, describe]:
1.) Existing site drainage is infiltration into site and runoff to the street that flows across the
existing developed single family residence site.
2.) Drainage from the site flows via mostly surface drainage to the south. A minor interior area
of the existing single family residence is picked up in area drain inlets and conveyed to the street
frontage gutter line via an existing 3-in. sidewalk underdrain.
3.) No runoff from off site conveys to site.
In general the site is has a mild slope to the south.
Site has very good infiltration rates per soils report and visible conditions. Asphalt and hardscape
areas drain to both the street and existing soil.

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 site stability after incorporation of infiltration facilities
The soils report performed for the project recommends no drainage or infiltration to or near
proposed structures.
As such the proposed drainage pattern is a combination of storm drain lines to planter areas
on site which then drain to qutter
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
future structures. 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 minimize the impervious areas of the future
facilities.

SUMMARY OF PDP STRUCTURAL BMPS
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 (1) Pervious Pavement System located
within the proposed project's entrance drive aisle.

INFILTRATION TESTING
Each proposed storm water infiltration BMP requires exploratory borings and in situ testing to
justify an infiltration recommendation. During the planning phase, City of Carlsbad, BMP Design
Manual dated February 16, 2016 (referred to hereon as Design Manual) recommends a feasibility
screening to assess the site conditions and potential for infiltration. Our investigation included test
borings at least ten feet below the potential BMP elevations, and one infiltration test to assess
preliminary infiltration rates.
The results of our field tests are shown in Figures C-1.1 and C-1.2. The test results are considered
preliminary and are not based on a specific site plan. Our preliminary conclusions about storm
water infiltration BMPs, based on the requirements of the Design Manual, are attached in the
completed Worksheet 1-8. The factor of safety applied for planning phase feasibility screening is 2.5
and shown attached in the completed Worksheet /-9.
The Borehole Percolation Test was used to help approximate infiltration rates of the soils near the
proposed infiltration zones. The test was set up by excavating a six-inch diameter test hole using a
hand-operated power auger (Appendix A). The hole was cleaned of loose material down to the
desired test depth. Perforated PVC casing was placed in the open hole. Open-graded gravel was
used to fill the annular space between the casing and the sidewalls of the test hole to support the
sidewalls of the test hole and prevent sloughing during saturation of the soil. Each hole was pre-
soaked prior to testing to more closely model saturated conditions and to achieve a stabilized
percolation rate.
The Borehole Percolation Test requires the hole to be filled with water to the test depth and the
rate of fall of water (percolation rate) to be measured periodically. To measure the percolation
rate, the drop of water in the hole (L~H) is measured at regular time intervals (~t). After each
reading, or a number of readings, when the water column has measurably dropped from the
desired test depth, water is added to the hole to maintain a relatively constant column of water in
the test hole (Havg),
During the test, water percolates into the surrounding ground both horizontally through the side
walls of the hole and vertically through the bottom of the hole. To more accurately approximate
the desired vertical infiltration rate (It), the percolation rate is modified mathematically. The Design
Manual recommends using a formula called the simplified Porchet method, shown below in
Equation 1 .
The simplified Porchet method assumes an open hole is used to measure the percolation rate
(~H/~t). Our hole was cased with perforated PVC pipe and gravel to stabilize the hole. The
measured drop in water (~H) is amplified by the fact that some space in the hole was occupied by
gravel, and not water. To account for this, the corrected drop in water (~He) is calculated by
reducing the measured drop in water by the ratio of the area of the hole occupied by water to the
total area of the hole. The porosity of the gravel was assumed to be 0.4 based on laboratory
testing of similar gravel.
A GROLP CELT.A
The percolation rate, and in turn, the infiltration rate, generated from the field tests are
dependent on the head pressure present during the tests. The percolation tests were run with
approximately 13 inches of water (head pressure, Havg), as shown in Figure C-1.1. If the BMP is
designed to accommodate significantly different head pressures, the infiltration rate provided
based on these field tests may not be applicable.

COMPLIANCE WITH STORMWATER BEST MANAGEMENT
PRACTICES MAINTENANCE REQUIREMENTS
All property owners are responsible for ensuring that stormwater best
management practices (BMPs) or facilities installed on their property are properly
maintained and that they function as designed. Tenants shall be aware of their
responsibilities regarding stormwater facility maintenance and need to be familiar
with the contents of this Operations and Maintenance Plan (O&M Plan). Property
Owners have signed and agreed to proper maintenance of these facilities in a
City of Carlsbad Maintenance Agreement (wet-signature copy to be maintained
in Attachment 12). In some cases, this maintenance responsibility may be
assigned to others through special agreements. All other maintenance
agreements between the property owner and their maintenance employees
associated with this property shall be included in Attachment 10.
DESIGNATION OF RESPONSIBLE PARTIES
Responsible parties shall be designated and identified in Table 1.
• The Responsible BMP Party is individual, party, or parties that shall have
direct responsibility for the maintenance of stormwater controls. This
individual shall be the designated contact with City inspectors and should
sign self-inspection reports and any correspondence with the City
regarding verification of inspections and required maintenance.
• The Duly Authorized Representative is the corporate officer authorized to
negotiate and execute any contracts that might be necessary for future
changes to operation and maintenance or to implement remedial
measures if problems occur.
• The Designated Emergency Respondent is the party responsible for
emergencies such as clogged drains, broken irrigation pipes, etc., that
would require immediate response should they occur during off-hours.

The funding for BMP operation and maintenance shall be described in Table 2,
including sources of funds, budget category for expenditures, process for
establishing the annual operations and maintenance budget, and process for
obtaining authority should unexpected expenditures for major corrective
maintenance be required. Any supplemental information, including calculations
and documentation shall be included in Attachment 3.
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.

330 Chinquapin Avenue, Carlsbad, CA
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:
O = 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.
BMP O&M PLAN 16
2=
3=
CITY OF CARLSBAD
BMP OPERATIONS AND MAINTENANCE PLAN
330 Chinquapin Avenue, Carlsbad, CA
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.
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
more costly rehabilitative maintenance that results when facilities are not
adequately maintained.

A. Maintenance Categories
CITY OF CARLSBAD
BMP OPERATIONS AND MAINTENANCE PLAN
330 Chinquapin Avenue, Carlsbad, CA
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
or an authorized agent of the property owner and made available for review upon
inspection by the City of Carlsbad.
BMP O&M PLAN 18

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.
