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

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.
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.
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
pay CITY's costs for performing MAINTENANCE ACTIVITIES, CITY may assess a lien on the

quality, pollutants of concem,:and post - construction BM-Ps.
! 1 Descriptions of the treatment control BMWs are as follows:
Bioretention Facility:
The proposed,bioretemion facility will consist of a landscaped area with approved planting soil (Sandy
Loam) in the upper 18" of the area capable of infiltrating water at a minimum of '5 in /hr. This areas shall not
be over compacted so that the plants present in the area can thrive. The upper 18 inches of plant soils shall
be underlain with class II perni material as described on the drainage:plans. This facility will have a 4"
perforated drain pipe placed at -the bottom of the class II perm course. The proposed facility- ll be located
in an existing landscape area in the parking lot south of the proposed building addition, as shown on the
BMP map in Appendix A.
Permeable paving:
The proposed'projectwill remove a section of existing landscaped area to accommodate the proposed
building. To mitigate this, 2,903 sf of existing standard ac pavement parking areas will be removed and
replaced with permeable pavement. The proposed permeable pavement areas will be bordered by deepened
�icurbs, and will feature a 6" pavement section underlain by a 12" class 11 perm base course with a 4"
' perforated sub drain. The location of the proposed area is shown on the BMP map in Appendix A

General Atomics Building 424 City of Poway Operations and Maintenance Plan
5.0 - Project O &M Information
Summary of Project Site and
The site is located at 11960 Tech Center Ct. Poway, CA 92064
The total property acreage is 10.4 acres (454,463 sf). As this project is a building addition, the site is
considered to be only 31,844 sf (0.73 ac) of this. The area this project will disturb is 31,844 sf (0.73 ac)
The project scope includes the construction of an 8,160 sf addition to the building. Additional
associated hardscape and landscaping will be constructed along with the building addition. The addition
is to house cooling units for the main building.
There are areas of landscaping that will be removed in favor of the new building addition footprint.
To mitigate the removalof landscaping, an area of existing impervious hardscape will be removed and
replaced with new permeable pavement.
2. Summary of WQTR:
The project will include, the following BMPs:
1) Pervious. Pavement - Porous concrete or asphalt, blocks with pervious spaces or joints, or
proprietary grass or gravel surfaces are employed to reduce runoff volume.
2) Bioretention - A bioretention facility will be constructed in the landscaped area in the parking lot
near the proposed building addition. The facility will have a perforated drain that connects to a
storm drain. Area is designed to overflow during high flow out of an curb inlet. Under low flow the
curb inlet allows runoff -in. Under high flow it allows runoff to overflow. The area was sized to have
a minimum of 18" of pervious planting material with an adequately sized bottom section of class II
perm material.
3) Education of Property owners and Employees —The property owner will review the educational
materials included in the :appendices and also distribute these materials to employees when hued and
at regular intervals. Although the materials are not specific to the jurisdiction , the concepts are

General Atomics Building 424 City of Poway Operations and Maintenance Plan
3.
The property owner, Sorrento West Properties, is the responsible; party to ensure that all BMPs .
described above will be implemented and maintained at the project site.
4. Inspection Program:
The property owner shall be,responsible for inspections or they shall appoint or hire another party
responsible for-the performance and periodic inspections of the applicable BMPs. Periodic inspections
shall meet the frequencies listed below:
1) Bioretention Areas — Bioretention facilities shall be inspected at a minimum of once every three
months and shall include constant observation of the surface areas directly around the facility. The
facility must also be inspected after each rainfall event to verify that there is no standing water 48
hours after the event. Adjacent areas must be free from sediment or mulch migration and.the facility
itself shall show no signs of rutting. During light rainfall, events (less than 0.60'in) the bioretention
area shall be inspected to make sure that there is little or no ponding. Ponding is expected with
larger rainfall events,.as the larger volume of stormwater takes more time to infiltrate. Theo" outlet
that drains to the bioretention basin must also be inspected at�the same interval as the bioretention
facility to make sure outlet has not become overgrown or blocked by vegetation and soil.
2) Pervious Pavement —The CASQA SD -20 informational packet contains information on pervious
pavements inspection protocol. The following is a summary of 'this information.
• Pervious Pavementareas shall be inspected annually to confirm permeability.
• Underdrain outlets shall be inspected annually to check for blockages.
• Pavement area shall be continuously visually inspected for sediment clogging
3) Landscape Areas —The landscaping area must be free and dear of debris. Soil or mulch must be
contained and not spreading out of the area. Atrium grates must be checked for blockage.
4) Efficient Irrigation System — The irrigation system shall be inspected at a minimum of once every
three months to ensure that the system is fully functional. Sprinkler heads should not be over
spraying landscaping, and the system must be operating at proper intervals to prevent over -
irrigation. The irrigation, system must be functioning in a manner that prevents runoff from
overflowing landscaped areas and site entering storm drains
An inspection log is provided as part of this O&M Plan and shall be filled out during each inspection.
The record of inspections shall be kept on site for a minimum of five (5) years. All BMPs shall be
inspected prior to the start of the rainy season (October 1st of each year). Treatment control BMPs will
require more frequent inspections. All BMPs identified in the SWMP and O &M Plan shall be inspected
at frequencies considered acceptable in the industry.

5. Maintenance Program:
The property, owner shall be responsible' "for maintenance or shall appointor hire another party
responsible for the maintenance of the applicable BMPs. Maintenance shall meet the frequencies listed
below.
1) Bioretention Areas —All areas shall be maintained at a minimum of once every three months.
Maintenance shall include removal of all trash or debris, and trimming /proper disposal of
vegetation- The maintenance shall also include insuring that the soil is not excessively compacted, if
so, localized scarification, or removal and reinstallation of top layer of planting soil may be required.
Should excessive ponding be observed during light rainfall events, (less than 0.60 ) localized soil
mitigation measure may be required. Ponding under larger rainfall events is expected as the larger
volume of stormwater takes-longer to infiltrate. If ponding exists 48 hours after any rainfall event,
scarification of the surface layer may be necessary. The bioretention area reflected as IMP -1 on the
BMP Location map shall be checked after each rain event.
2) Efficient Irrigation System — System shall be maintained at a minimum of once every three months
or as needed. Maintenance will include the repair or adjustment of broken or misaligned sprinkler
heads, adjustment: of irrigation watering intervals and calibrating the system to prevent over -
irrigation.
3) Permeable Pavement - Street sweeping with a regenerative air sweeper shall be conducted 2 -3 times
annually„ as outlined in the CASQA informational packet TC -32, to prevent clogging and maintain
longterm permeability. The following items area a summary of the informational packet.
Ongoing Maintenance
- Keep landscaped areas well maintained
- Prevent soil from being washed onto the pavement
As Needed (15 year maxi
-If routine cleaning does not restore infiltration rates, the reconstruction of part or all of the
pervious surface may be required
-The surface area affected by hydraulic failure should be lifted for inspection of the internal
materials.
- Surface layers may need cleaning and replacement.
- Removed silts and soil may need to be disposed of as controlled waste.
Proper maintenance is imperative for BMP effectiveness and longevity. All BMPs identified in the
SWivIP and O &M Plan shall be maintained to provide optimum effectiveness in accordance with
industry standards.
Include the San Diego County Department of Environmental Health Vector Surveillance and Control
Program phone number as a reference for vector issues, 1- 858- 694 -2888
A maintenance log shall, be, provided and filled out after maintenance activities are completed. The
records of maintenance shall be kept on site for a minimum of five (5) years.
6. Record Keeping:
A maintenance log is included and shall be filled out after every maintenance event is completed. The
records of.maintenance "shall be kept on site for a minimum of five (5) years, and shall be made available
to the
