Poway Corporate Center 11885 and 11895 Community Road
(G14 -0010)
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 Management Facilities is
entered into between the Property Owner(s) Tech Business Center Ventures, L.P., and California
limited partnership, (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 into two industrial building sites, in accordance with applications for Development
Review 13 -011, and Grading Permit No. G14 -0010, which are on file with the CITY. This Agreement
is required as a condition of approval for such development.
WHEREAS, in accordance with the City of Poway's Standard Urban Storm Water Mitigation Plan,
Poway Municipal Code, Chapter 16, Division VI (the "SUSMP 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 from the PROPERTY be managed by the use of the
following Storm Water Management Facilities which are identified as "Best Management Practices" or
"BMPs ":
Four flow- through planter basins, with associated outlet structures and "no- dumping" stenciling, all as
shown on the approved grading plans.
The precise location(s) and extent of the BMPs are indicated in the approved Water Quality Technical
Report for Poway Corporate Center, and on the approved grading and erosion control plans for
Poway Corporate Center on file with CITY's Development Services Department as G14 -0010. The
manner and standards by which the BMPs must be repaired and maintained in order to retain their
effectiveness are as set forth in the Operation and Maintenance Plan (hereinafter "O &M PLAN "),
which is attached hereto and incorporated herein as Exhibit "B ".
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:
Maintenance of Storm Water Management 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 SUSMP 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.
2. 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.
3. 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, shall be deemed to be accepted by OWNER "as is ", and shall be
covered by OWNER's 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
SWMFMA Page 2
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.
4. 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 shall have the right, at any time and without prior notice to OWNER, to enter
upon any part of said area as may be necessary or convenient for such purposes. OWNER
shall at all times maintain the PROPERTY so as to make CITY's access clear and
unobstructed.
5. Administration of Agreement for CITY. CITY hereby designates the City Engineer as the
officer charged with responsibility and authority to administer this Agreement on behalf of
CITY. Any notice or communication to the City related to the implementation of this
Agreement shall be addressed to:
City Engineer
City of Poway
13325 Civic Center Drive
Poway, CA 92064
6. Defense and Indemnity. CITY shall not be liable for, and OWNER and its successors in
interest shall defend and indemnify CITY and the employees and agents of CITY (collectively
"CITY PARTIES "), against any and all claims, demands, liability, judgments, awards, fines,
mechanic's liens or other liens, labor disputes, losses, damages, expenses, charges or costs
of any kind or character, including attorneys' fees and court costs (hereinafter collectively
referred to as "CLAIMS "), related to this Agreement and arising either directly or indirectly from
any act, error, omission or negligence of OWNER, OWNER's successors, or their contractors,
licensees, agents, servants or employees, including, without limitation, claims caused by the
concurrent negligent act, error or omission, whether active or passive, of CITY PARTIES.
OWNER shall have no obligation, however, to defend or indemnify CITY PARTIES from a
claim if it is determined by a court of competent jurisdiction that such claim was caused by the
sole negligence or willful misconduct of CITY PARTIES. Nothing in this Agreement, CITY's
approval of the development application or plans and specifications, or inspection of the work
is intended to acknowledge responsibility for any such matter, and CITY PARTIES shall have
absolutely no responsibility or liability therefore unless otherwise provided by applicable law.
7. Allocation of Costs. Following the sale or transfer of any of the individual lots by OWNER,
the cost of the MAINTENANCE ACTIVITIES required by this Agreement shall be divided
equally by all lot owners, and paid by each lot owner or his or her heirs, assigns and
successors in interest. This requirement shall be binding on all lot owners, and each shall be
responsible for his or her equal share of the cost associated with the maintenance.
8. Agreement Binds Successors and Runs With the PROPERTY. It is understood and
agreed that the terms, covenants and conditions herein contained shall constitute covenants
running with the land and shall be binding upon the heirs, executors, administrators,
successors and assigns of OWNER and CITY, shall be deemed to be for the benefit of all
persons owning any interest in the PROPERTY (including the interest of CITY or its
successors in the easement granted herein). It is the intent of the parties hereto that this
Agreement shall be recorded and shall be binding upon all persons purchasing or otherwise
acquiring all or any lot, unit or other portion of the PROPERTY, who shall be deemed to have
consented to and become bound by all the provisions hereof.
SWMFMA Page 3

Notwithstanding any other provision of this Agreement, no transfer or conveyance of the
PROPERTY or any portion thereof shall in any way relieve OWNER of or otherwise affect
OWNER's responsibilities for installation or maintenance of BMPs which may have arisen
under the ordinances or regulations of CITY referred to in this Agreement, or other federal,
state or CITY laws, on account of OWNER having obtained a permit which creates such
obligations or having commenced grading, construction or other land disturbance work.
10. Amendment and Release. The terms of this Agreement may be modified only by a written
amendment approved and signed by the Director of Development Services acting on behalf of
CITY and by OWNER or OWNER's successor(s) in interest. This Agreement may be
terminated and OWNER and the PROPERTY released from the covenants set forth herein, by
a release, which CITY may execute if it determines that another mechanism will assure the
ongoing maintenance of the BMPs or that it is no longer necessary to assure such
maintenance.
11. Governing Law and Severability. This Agreement shall be governed by the laws of the
State of California. Venue in any action related to this Agreement shall be in the Superior
Court of the State of California, County of San Diego. OWNER hereby waives any right to
remove any such action from San Diego County as is otherwise permitted by California Code
of Civil Procedure Section 394. In the event that any of the provisions of this Agreement are
held to be unenforceable or invalid by any court of competent jurisdiction, the validity, and
enforceability of the remaining provisions shall not be affected thereby.

1. PROJECT DESCRIPTION
The project consists of constructing two industrial buildings with the associated underground utilities,
landscaping, storm drains, bioretentions for stormwater treatment and outdoor parking and
hardscaping.
2. OPERATION & MAINTENANCE PLAN
The Operation and Maintenance Plan (O &M) needs to address construction and post- construction
concerns as shown in the Storm Water Mitigation Plan. Refer to this project's Water Quality
Technical Report (WQTR) for additional information on BMPs. (See enclosed attachment for location
of BMPs)
3. Operation & Maintenance of BMP'S
It shall be the responsibility of the owner to maintain and to train all employees for the maintenance
and operation of all BMPs, to achieve the maximum pollutant reduction they are designed for, as
addressed in the approved Project's WQTR. The following schedule of (O &M's) must be followed to
satisfy the Conditions of Concern and the Pollutants of Concern as addressed in the approved
Project's WQTR and the City's SUSMP. This schedule shall include periodic inspections of all
Source Control and Treatment Control BMP's. All maintenance records for training, inspection and
maintenance shall be kept for a minimum of five (5) years.
All BMPs shall be inspected 30 days prior to October Is' each year and certified to the City
Engineering Department as to their readiness to receive runoff from the annual rainfall season (See
enclosed attachment for a more detailed schedule of maintenance)
The owner will also, provide to the City as part of the maintenance and operation agreement an
executed access easement that shall be binding on the land throughout the life of the project.
• Removal of standing water, which may contribute to the development of aquatic plant
communities or mosquito breeding areas.
• Preventive maintenance on sampling, flow measurement, and associated BMP equipment and
structures.
• Erosion and structural maintenance to prevent the loss of soil and maintain the performance of
all landscaping.
Inspection Frequency
The facility will be inspected and inspection visits will be completely documented:
Once a month at a minimum.
After every large storm (after every storm monitored or these storms with more than 0.50 inch of
precipitation.)
On a weekly basis during extended periods of wet weather.
Inspect for proper irrigation and fertilizer use, and ensure that all landscaped areas have minimum of
80% coverage.
Aesthetic Maintenance
The following activities will be included in the aesthetic maintenance program:
Grass Trimming: Trimming of grass will be done on all landscaped areas, around fences, at the inlet
and outlet structures, and sampling structures.
Weed Control. Weeds will be removed through mechanical means. Herbicide will not be used
because these chemicals may impact the water quality monitoring.
Functional Maintenance
Functional maintenance has two components:
• Preventive maintenance
• Corrective maintenance
Preventive Maintenance
Preventive maintenance activities to be instituted for landscaped areas are:
• Grass Mowing: Vegetation seed, mix within the landscaped areas, are to be designed to be
kept short to maintain adequate hydraulic functioning and to limit the development of faunal
habitats.
• Trash and Debris: During each inspection and maintenance visit to the site, debris and trash
removal will be conducted to reduce the potential for inlet and outlet structures and other
components from becoming clogged and inoperable during storm events.
• Sediment Removal: Sediment accumulation, as part of the operation and maintenance program
at of landscaped areas, will be monitored once a month during the dry season, after every large
stone (0.50 inch), and monthly during the wet season. Specifically, if sediment reaches a level
at or near plant height, or could interfere with flow or operation, the sediment will be
3
Maintenance Frequency
The maintenance indicator document included in enclosed Attachment Al for all BMPs lists the
schedule of maintenance activities to be implemented.
Debris and Sediment Disposal
Waste generated onsite is ultimately the responsibility of the Owner. Disposal of sediments, debris,
and trash will comply with applicable local, county, state, and federal waste control programs.
Hazardous Waste
Suspected hazardous wastes will be analyzed to determine disposal options. Hazardous wastes
generated onsite will be handled and disposed of according to applicable local, state, and federal
regulations. A solid or liquid waste is considered a hazardous waste if it exceeds the criteria listed in
the CCR, Title 22, Article 11.
C. Irrigation System
Inspection Frequency and Procedure
The Irrigation system shall be checked each week as a minimum. The following items shall be
checked to insure that they are functioning properly:
• Shut -off devices.
• All piping and sprinkler heads to insure there are no leaks and that proper water spread is
maintained.
• All flow reducers.
• Check for overspray /runoff
D. Roof Drains
All roof drains shall be inspected 30 days prior to October 15t of each year to insure that they are clean
and free from trash and in good repair. They shall be flushed and any leaks or damages piping shall be
either replaced or repaired. Where roof drains flow onto grass areas splash structures and or rock rip -
rap shall be maintained so the flow from the roof drains do not cause erosion or damage to the grass
area. During the rain season roof drains shall be inspected weekly and after each rain storm to insure
that there is no trash and or silt build up that will restrict the run -off flow from the roof. All trash
and /or silt build up shall be removed immediately.
E. Trash Storage Areas
■ All trash storage areas shall be inspected daily to insure that they are clean from trash. Also the
following shall be inspected annually 30 days prior to October 1 st of each year.
■ Pavement is in good repair.
■ Drainage will not run -off onto adjacent areas.
■ That they remain screened or walled to prevent off -site transport of trash.
■ That all lids are closed and /or awnings are in good repair to minimize direct
precipitation.
5
• Preventive maintenance
• Corrective maintenance
Preventive Maintenance
Preventive maintenance activities to be instituted:
• Trash and Debris: During each inspection and scheduled maintenance period, trash and debris shall
be removed in order to minimize runoff contamination and to prevent downstream inlet and outlet
structures from becoming clogged and inoperable during storm events.
• Sediment Removal: Sediment accumulation, as part of the operation and maintenance program at of
landscaped areas, will be monitored once a month during the dry season, after every large storm
(0.50 inch) and monthly during the wet season. Sediment shall be removed immediately if it is
visibly accumulated and interferes with drainage flow. and /or removing accumulated sediment to
correct channeling or ponding. Characterization and Appropriate disposal of sediment shall comply
with applicable local, county, state, or federal requirements.
• Removal of Standing Water: Standing water must be removed if it contributes to the development of
aquatic plants or mosquito breeding areas. The most effective mosquito control program is one that
eliminates potential breeding habitats. (Remove if water is present 72 -hours after rain event).
• Erosion: Damages from erosion shall be repaired to the original condition.
Corrective Maintenance
Corrective maintenance is required on an emergency or non - routine basis to correct problems and to
restore the intended operation and safe function of all landscaped areas.
Corrective maintenance activities include:
Removal of Debris and Sediment: Sediment, debris, and trash, which impede the hydraulic
functioning of landscaping and prevent vegetative growth, will be removed and properly disposed.
Temporary arrangements will be made for handling the sediments until a permanent arrangement is
made. Vegetation will be re- established after sediment removal.
Structural Repairs: Once deemed necessary, repairs to structural components of landscaping will be
done within 10 working days. Qualified individuals (i.e., the designers or contractors) will conduct
repairs where structural damage has occurred.
Embankment and Slope Repairs: Once deemed necessary, damage to the embankments and slopes of
landscaped areas will be repaired within 10 working days.
Erosion Repair: Where a reseeding program has been ineffective, or where other factors have created
erosive conditions (i.e., pedestrian traffic, concentrated flow, etc.), corrective steps will be taken to
prevent loss of soil and any subsequent danger to the performance and use of landscaped areas as
BMPs. There are a number of corrective actions than can be taken.
These include erosion control blankets, riprap, sodding, or reduced flow through the area. Designers
or contractors will be consulted to address erosion problems for a permanent solution.
Elimination of Animal Burrows
Animal burrows will be filled and steps taken to remove the animals if burrowing problems continue
to occur (filling and compacting). If the problem persists, vector control specialists will be consulted
