STORM WATER TRASH FACILITIES
MAINTENANCE AGREEMENT
15721 and 15725 Pomerado Rd
(B21-2684/TA22-0001)
The undersigned grantor(s) declares:
Documentary Transfer Tax is $ -0- pursuant to R & T Code 11922 (conveyance to a Government Agency)
This AGREEMENT for the maintenance and repair of certain Storm Water Trash Facilities is entered
into between the Property Owner(s) HCP Inc, (hereinafter referred to collectively as "OWNER") and the
City of Poway (hereinafter referred to as "CITY") for the benefit of the CITY, the OWNER, the successors
in interest to the CITY or the OWNER, and the public generally.
WHEREAS, OWNER is the owner of certain real property located in the City of Poway, California, more
particularly described in Exhibit "A", hereto (hereinafter referred to as the "PROPERTY"), which is being
developed in accordance with applications for a Building Permit Number B21-2684, which are on file
with the CITY. This Agreement is required as a condition of approval for such development.
WHEREAS, in accordance with the California Regional Water Quality Control Board San Diego Region
Order Number R9-2017-0077, (hereinafter referred to collectively as "Trash Amendment"), the City of
Poway's Stormwater Management and Discharge Control Ordinance, Poway Municipal Code, Chapter
13 and 16 (the "Stormwater Ordinance"), the City of Poway Subdivision Ordinance, the City of Poway
Zoning Ordinance, the City of Poway Grading Ordinance and/or other ordinances or regulations of CITY
which regulate land development and urban runoff, OWNER has proposed that storm water runoff and
trash generation from the PROPERTY be managed by the use of the following Storm Water Trash
Facilities which are identified as "Best Management Practices" or "BMPs":
Three (3) Bio Clean Curb Inlet Filter and two (2) Bio Clean Grate Inlet filters located throughout the
site as shown on Exhibit "B".
The precise location(s) and extent of the BMPs are indicated on the approved building plans on file with
CITY's Development Services Department as B21-2684. The manner and standards by which the
BMPs must be repaired and maintained in order to retain their effectiveness and the approximate
location of the BMPs are as set forth in the Operation and Maintenance Plan (hereinafter "O&M PLAN"),
which is attached hereto and incorporated herein as Exhibit "C".
Because additional impervious area may require the addition of or alteration of storm water facilities
SWTFMA (B21-2684/TA22-0001) 2,-L"db(o
and strategies, no impervious area or additional drains may be added to the project site without prior
approval from the City Engineer.
WHEREAS, OWNER's representations that the BMPs will be maintained have been relied upon by
CITY in approving OWNER's development applications. It is the purpose of this Agreement to assure
that the BMPs are maintained, by creating obligations that are enforceable against the OWNER and
the OWNER's successors in interest in the PROPERTY. It is intended that these obligations be
enforceable notwithstanding other provisions related to BMP maintenance that are provided by law.
NOW, THEREFORE, for consideration of (a) CITY's approval of the above development applications
and (b) the mutual covenants set forth herein, IT IS HEREBY AGREED AS FOLLOWS:
Incorporation of Recitals. The recitals set forth above are incorporated herein by this reference
and constitute a part of this AGREEMENT
2. Maintenance of Storm Water Trash Facilities. OWNER agrees, for itself and its successors
in interest, to all or any portion of the PROPERTY, to comply in all respects with the requirements
of the Stormwater Ordinance with regards to the maintenance of BMPs, and in particular agrees
to perform, at its sole cost, expense and liability, the following "MAINTENANCE ACTIVITIES":
all inspections, cleaning, repairs, servicing, maintenance and other actions specified in the O&M
PLAN, with respect to all of the BMPs listed above, at the times and in the manner specified in
the O&M PLAN. OWNER shall keep records of this maintenance and provide copies of such
records and annual certification of maintenance as requested by CITY. OWNER shall initiate,
perform and complete all MAINTENANCE ACTIVITIES at the required time, without request or
demand from CITY or any other agency. OWNER further agrees that "MAINTENANCE
ACTIVITIES" shall include replacement or modification of the BMPs in the event of failure.
Replacement shall be with an identical type, size and model of BMP, except that:
(a) The City Engineer may authorize substitution of an alternative BMP if he or she
determines that it will be as effective as the failed BMP; and
(b) If the failure of the BMP, in the judgment of the City Engineer, indicates that the BMP in
use is inappropriate or inadequate to the circumstances, the BMP must be modified or
replaced with a more effective BMP to prevent future failure in the same or similar
circumstances.
3. Notices. OWNER further agrees that it shall, prior to transferring ownership of any land on
which any of the above BMPs are located, or any lot or portion of the PROPERTY which is
served by the above BMPs, and also prior to transferring ownership of any such BMP, provide
clear written notice of the above described maintenance obligations to the transferee.
4. CITY's Right to Perform Maintenance. It is agreed that CITY shall have the right, but not the
obligation, to elect to perform any or all of the MAINTENANCE ACTIVITIES if, in the CITY's sole
judgment, OWNER has failed to perform the same. Such maintenance by the CITY shall be
conducted in accordance with the nuisance abatement procedures set forth in Poway Municipal
Code Chapter 8.72. In the case of maintenance performed by the CITY, it may be performed
by CITY forces, or a contractor hired by the CITY, at the CITY's sole election. It is recognized
and understood that the CITY makes no representation that it intends to or will perform any of
the MAINTENANCE ACTIVITIES, and any election by CITY to perform any of the
MAINTENANCE ACTIVITIES shall in no way relieve OWNER of its continuing maintenance
obligations under this agreement. If CITY elects to perform any of the MAINTENANCE
ACTIVITIES, it is understood that CITY shall be deemed to be acting as the agent of the OWNER
and said work shall be without warranty or representation by CITY as to safety or effectiveness,
SWTFMA (B21-2684/TA22-0001) Page 2

indemnity provisions below.
If CITY performs any of the MAINTENANCE ACTIVITIES, after CITY has demanded that
OWNER perform the same and OWNER has failed to do so within a reasonable time stated in
the CITY's demand, then OWNER shall pay all of CITY's costs incurred in performing the
MAINTENANCE ACTIVITIES, plus an administrative fee. OWNER's obligation to pay CITY's
costs of performing MAINTENANCE ACTIVITIES is a continuing obligation. If OWNER fails to
pay CITY's costs for performing MAINTENANCE ACTIVITIES, CITY may assess a lien on the
property or properties of the responsible parties pursuant to the procedures set forth in Poway
Municipal Code Chapter 8.72.
5. Grant of Easement to CITY. OWNER hereby grants to CITY a perpetual easement over, under
and across all of the PROPERTY, for purposes of accessing the BMPs, inspecting the BMPs,
and performing any of the MAINTENANCE ACTIVITIES specified in Paragraph 1 above. CITY

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
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 Curb 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 Curb Inlet Fitter 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 Curb Inlet Filter can be inspected though visual observation without entry into the catch basin.
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 access hatch or manhole. Once the manhole has been safely opened 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 inside of the catch basin through the manhole. If minimal light is available and
vision into the unit is impaired utilize a flashlight to see inside the catch basin.
• Look for any out of the ordinary obstructions in the catch basin, trough, weir, filter basket,
basin floor our outlet pipe. 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.
2 1 P a g e
B AClean
io ,

• 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 trough, weir, filter basket or catch basin.
• Excessive accumulation of trash, foliage and sediment in the filter basket and/or trough and
weir sections. Maintenance is required when the basket is greater than half -full.
• The following chart shows the 50% and 100% storage capacity of each filter height:

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 0&M Manual).
• Manhole hook or appropriate tools to access hatches and covers.
• 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 Curb Inlet Filter can be
performed from finish surface without entry into catch basin utilizing a vacuum truck. Some unique
3 1 P a g e
A Forterra Company
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
bullet point. If replacement is required install and fasten on a new hydrocarbon boom.
Booms can be ordered directly from the manufacturer.
• Follow is a replacement indication color chart for the hydrocarbon booms:
Excellent Good Minimal Replacement
Condition Condition Capacity I Required
• 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. Hydrocarbon booms can also be ordered directly from the manufacturer as
previously noted,

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.
• The following chart shows the 50% and 100% storage capacity of each filter height:

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 0&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:

• Remove grate (traffic control and safety measures to be completed prior).
• Using an extension on a vacuum truck position the hose over the opened catch basin. 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. Power wash off the 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
bullet point. If replacement is required install and fasten on a new hydrocarbon boom.
Booms can be ordered directly from the manufacturer.
• Follow is a replacement indication color chart for the hydrocarbon booms:
Excellent Good Minimal Replacement
Condition Condition Capacity I Required
• The last step is to replace the grate 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. Hydrocarbon booms can also be ordered directly from the manufacturer as
previously noted.
