This AGREEMENT replaces the previously recorded Storm Water Management Facilities Maintenance Agreement, recorded August 7, 2013 as document number 2013 - 0495391. WHEREAS, OWNER is the owner of certain real property located in the City of Poway, California, more particularly described as Lot 25 of City of Poway Tract No. 89 -13R The Heritage Phase 1, Unit 1, in the City of Poway, County of San Diego, State of California, according to map thereof No. 13708, filed in the office of the County Recorder of San Diego County December 17, 1998 (hereinafter referred to as the "PROPERTY "), which is the development of a single - family residence, in accordance with applications for Minor Development Review Application 12 -054, and Building Permit No. B13 -0428, 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 a bioretention basin at the base of a manufactured slope east of the main building pad, shown on the schematic on the last page of Exhibit "A ". The precise location and extent of the BMPs are indicated in the approved Water Quality Technical Report Replacement Addendum 14480 Cheyenne Trail, prepared by Tory R. Walker Engineering dated November 20, 2014, on file with CITY's Development Services Department. 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 "A ". 15- DO Because additional impervious area may require the addition of or alteration of storm water management areas and strategies, no impervious area may be added to the project site without prior approval from the City Engineer. Additional impervious area includes, but is not limited to, patio covers, hardscape improvements, and building additions. 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. 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 SWFMA (613 -0428) Page 2 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. 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.

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. Allocation of Costs. Following the sale or transfer of any of the 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 be responsible for his or her equal share of the cost associated with the maintenance. 8.

Ensure vegetation is healthy and dense enough to provide filtering and to protect soils from erosion. Replenish mulch as necessary (if less than 3 inches deep), remove fallen leaves and debris, rune large shrubs or trees, and mow turf areas. Mow or trim as appropriate, but not less than the design height of the vegetation (typically 4.6 inches for grass).
