STEP4
TO BE COMPLETED FOR REDEVELOPMENT PROJECTS THAT ARE PRIORITY DEVELOPMENT PROJECTS (PDP)
ONLY
Complete the questions below regarding your redevelopment project (MS4 Permit Provision E.3.b.(2)):
YES NO
Does the redevelopment project result in the creation or replacement of impervious surface in an amount of
less than 50% of the surface area of the previously existing development? Complete the percent impervious
calculation below:
Existing impervious area (A) = N/A sq. ft. □ □
Total proposed newly created or replaced impervious area (8) = N/A sq. ft.
Percent impervious area created or replaced (B/A)*100 = N/A %
If you answered "yes", the structural BMPs required for PDP apply only to the creation or replacement of impervious surface
and not the entire development. Go to step 5, complete the trash capture question.
If you answered "no," the structural BM P's required for PDP apply to the entire development. Go to step 5, complete the
trash capture question.
STEP5
TO BE COMPLETED FOR ALL DEVELOPMENT PROJECTS
Complete the question below regarding your Project (SDRWQCB Order No. 2017-0077):
YES NO
Is the Project within any of the following Priority Land Use (PLU) categories?
R-23 (15-23 du/ac), R-30 (23-30 du/ac), Pl (Planned Industrial), CF (Community Facilities), GC (General 181 □ Commercial), L (Local Shopping Center), R (Regional Commercial), V-8 (Village-Barrio), VC (Visitor
Commercial), 0 (Office), VC/OS (Visitor Commercial/Open Space), Pl/O (Planned Industrial/Office), or
Public Transoortation Station
If you answered "yes", the 'PROJECT' is subject to TRASH CAPTURE REQUIREMENTS. Go to step 6, check the first
box stating, "My project is subject to TRASH CAPTURE REQUIREMENTS ... " and the second or third box as
determined in step 3.
If you answered "no", Go to step 6, check the second or third box as determined in step 3.
STEP&
CHECK THE APPROPRIATE BOX(ES) AND COMPLETE APPLICANT INFORMATION
181 My project is subject to TRASH CAPTURE REQUIREMENTS and must comply with TRASH CAPTURE
REQUIREMENTS of the BMP Manual. I understand I must prepare a Storm Water Quality Management Plan (SWQMP).
181 My project is a 'STANDARD PROJECT' OR EXEMPT from PDP and must only comply with 'STANDARD PROJECT'
stormwater requirements of the BMP Manual. As part of these requirements, I will submit a "Standard Project
Requirement Checklist Form E-36" and incorporate low impact development strategies throughout my project. If my
project is subject to TRASH CAPTURE REQUIREMENTS, I will submit a TRASH CAPTURE Storm Water Quality
Management Plan (TCSWQMP) per E-35A.

prepare a Storm Water Quality Management Plan (SWQMP) per E-35 template for submittal at time of application.
Note: For projects that are close to meeting the PDP threshold, staff may require detailed impervious area calculations
and exhibits to verify if 'STANDARD PROJECT' stormwater requirements apply.

Description/ Additional Information:
Description of Existing Site Topography and Drainage [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; and (3) is runoff from offsite conveyed through the site? if so, describe]:
The Existing Site can be categorized into one major drainage basin, with two sub-basins
and two primary discharge locations leaving the property. Drainage Basin EX-1 consists
of the majority of the project site and primarily drains south to north discharging to Hope
Avenue right-of-way by surface and sheet flow methods. Once in the Hope Avenue
right-of-way, runoff leaving the site travels northwest to the Home Avenue intersection.
Runoff then travels southwest to the Jefferson Street intersection and then Southeast
along Jefferson Street until it is intercepted by a ribbon gutter on Grand Avenue and
where an existing storm drain inlet is located. Drainage Basin Ex-2 is a small portion of
the site where excess runoff drains onto Grand Avenue. Once in the Grand Avenue
right-of-way, runoff travels southwest entering the existing storm drain inlet. Surface
flows entering the storm drain inlet ultimately are conveyed to outlet in the Buena Vista
Lagoon prior to entering the Pacific Ocean.
After review of the site edge conditions, existing topography, and adjacent
developments, it was determined that there is no additional offsite run on entering the
site from the neighboring properties.
Description of Proposed Site Development and Drainage Patterns
Project Description / Proposed Land Use and/or Activities:
This project scope includes the demolition of all existing onsite improvements and the
construction of a new medical office building. The construction of the new building will
include site grading, as well as drainage and utility improvements typical to this type of
commercial development.
Does the project include grading and changes to site topography?
0Yes
□No
Description/ Additional Information:
The project proposed to precise grade the site along with some changes to onsite
topography of the onsite grading. This consists of approximately 53 CY of cut and 16 CY
of fill, resulting in 37 CY of export.
Does the project include changes to site drainage (e.g., installation of new storm water
conveyance systems)?
@Yes
□No
Description / Additional Information:
The proposed drainage system has two proposed trash capture devices and area drains
that will discharge via a sidewalk under drain on Hope Avenue and Grand Avenue. Once
off the site, runoff flows to Grand Avenue to the existing curb inlet similar to
predeveloped conditions.

SUMMARY OF TRASH CAPTURE BMPS
.. * . Trash Capture BMP$
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 ca_pture 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).
The trash capture BMP was selected using the rational method to determine the flowrate
to each grate inlet and CASQA's list of approved trash capture BMPs. Two DMA's were
created for two inlets with the pipe screen connector inside, runoff coefficients were
calculated from a weighted average of the impervious and pervious areas of the site, and
the rainfall intensity was taken from Appendix J of the BMP design manual. The rational
method calculations are included in attachment 1 c. After calculating the flow rate, a
REM Triton TDAM Filter was selected based on its treatment flow rate being higher than
then the flowrate the grate inlet will receive. REM Triton TDAM Filter has an aperture
less than 5mm ensuring capture of all particles 5mm in size or larger.

strategy for trash capture BMP implementation at the site.]

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
