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 undergoing tenant improvements, in accordance with the application for Building Permit Number B20- 0111, which is 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 Management Facilities which are identified as "Best Management Practices" or "BMPs": Six (6) Advanced Drainage Systems (ADS) Flexstorm 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 B20-0111. 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". SWMFMA (TA20-012) 2 C Because additional impervious area may require the addition of or alteration of storm water management facilities 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: 1. 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 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 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 SWMFMA (TA20-012) Page 2 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 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 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. 6. 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 7. 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 (specifically including but not limited to OWNER's alleged noncompliance with the Trash Amendment or the Stormwater Ordinance), 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. 8. Allocation of Costs. Following the sale or transfer of any individual residential 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 in the subdivision, and each shall SWMFMA (TA20-012) Page 3 be responsible for his or her equal share of the cost associated with the maintenance. 9. 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. 10. OWNER's Continuing Responsibilities Where Work Commenced or Permit Obtained. 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. 11. 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. 12. 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. 13. Attorney's Fees. The prevailing party in any action or proceeding to enforce or interpret the terms of this Agreement shall be entitled to recover all of its reasonable litigation expenses, including its expert fees, attorneys' fees, courts costs, arbitration costs, and any other fees.

Flow Ratings, 2. Bypass Requirements, 3. Location of Connector Pipe inside the catch basin (see Product Selection Guide). 2.0 Materials: All FLEXSTORM CPS are comprised entirely of 304 stainless steel and brought to the field pre -configured for easy assembly once Product Selection is confirmed; All Models are supplied with vertical upright mounting brackets which accept qty (4) 3/8" x 3" minimum stainless anchor bolts. All bypass lids require a qty (2) 3/8" x 3" min stainless anchor bolts. Mounting brackets are equipped with slotted holes to allow for varied contours on walls and sloped floors. 3.0 Installation of Base Model: Drop CPS through the manhole opening. Position the CPS evenly spaced around the connector pipe ensuring a minimum of 4" spacing away from any corners. Loosen the bolts in the slotted holes which connect the screen to the upright mounting brackets until the bottom is flush with the floor. Tighten the bolts and mark the hole locations on the wall for the stainless anchor bolts. Drill holes and hammer the bolts in place and secure the CPS using stainless nuts. If the bottom of the base exposes more than a 5 mm gap then an additional base face strip may be fastened to the base channel using stainless tek screws or rivets. This base face strip matches the length and contour of the primary base. 3.1 Installation of Bypass Lid: If the bypass lid is required verify the minimum bypass height needed and mark the "B" bypass height location on the wall directly above the base uprights. Lift the lid in place and mark the hole locations for the lid mounting brackets. Drill holes and hammer the bolts in place and secure the lid with the stainless nuts. 4.0 Removal of CPS: In certain locations, the CPS may need to be removed in order to provide increased accessibility through the manhole entry. In such cases, the CPS would utilize the "Quick Release" wall mount bracket set and standard CPS flanges. See the installation drawing labeled Removable CPS Detail for step by step instructions. In standard installations, the CPS can be removed by simply loosening the 3/8" anchor nuts that secure it to the wall. 5.0 Warranty: ADS — FLEXSTORM warrants the CPS material to be free of defects and guarantees base framing integrity for a period of 3 years from installation date. 3 ADS - FLEXSTORM CONNECTOR PIPE SCREEN (CPS) MAINTENANCE GUIDELINES FLEXSTORM suggests that its Connector Pipe Screens (CPS) be maintained per this modified set of conditions from the LA County CPS Standards. FLEXSTORM advises that catch basins be cleaned out at least 2 times per year and/or if debris has filled above a 40% level inside of the catch basin. Sites with large amounts of foliage, high sediment loads, or smaller CPS devices might need to be cleaned more frequently. Maintenance Conditions and Maintenance Standards: The Following are deficiencies in maintenance conditions and their corresponding maintenance standards which shall apply to the Connector Pipe Screen. The cleanout of each CB shall meet the maintenance standards listed as follows: Trash and debris shall include, but is not limited to, mud, vegetation, and garbage. Upon completion of a cleanout operation at a CB and before leaving it, the Contractor shall sweep the top surface of the CB and the area 2 feet around the CB, and shall remove any trash and debris resulting from the cleanout operations. No debris is to be left at a CB for future pick-up. Method of Removal: All trash and debris required to be removed from the CBs shall be removed in a manner to be determined by the Contractor. This can be done by hand or with a truck mounted vacuum. If entering the catch basin ensure that local confined space entry procedures are followed. The Contractor shall not allow any trash or debris to enter the connector pipe or main line as a result of the cleanout operations. Debris Disposal: All trash and debris removed under this Contract shall become the property of the Contractor and shall be legally disposed of away from the CB sites. The Contractor is responsible for proper disposal of the trash and debris, including obtaining approvals from all jurisdictional agencies, as applicable. The contractor shall be responsible for contacting and coordinating with local Animal Care and Control for pickup and disposal of dead animals.
