Filhart and Kimanh G. Filhart, (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 as Lot 2 of Parcel Map 9452, in the County of San Diego, State of California, filed in the Office of the County Recorder of San Diego County, December 6, 1979 (hereinafter referred to as the "PROPERTY"), which is being developed into a single-family residence, in accordance with Minor Development Review Application 17-008 and Grading Permit Number G16-0014, 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 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 from the PROPERTY be managed by the use of the following Storm Water Management Facilities which are identified as "Best Management Practices" or "BMPs": Biofiltration basins, pervious pavers, and landscaped areas located throughout the site as shown in Exhibit "A". The precise locations and extent of the BMPs are indicated in the approved Storm Water Quality Management Plan, dated August 18, 2017, and on the approved grading plans on file with CITY's Development Services Department as G16-0014. 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 "B". 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 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. 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 SWFMA Filhart (G16-0014) Page 2 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. 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 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. SWFMA Filhart (G16-0014) Page 3 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. 9. OWNER's Continuing Responsibilities Where Work Commenced or Permit Obtained.

In accordance with City of Poway requirements and as part of the grading permit process, a Storm Water Quality Management Plan (SWQMP) has been prepared for the project, which describes certain onsite Best Management Practices (BMP) improvements that will be utilized for water quality treatment. One of the requirements of the SWQMP is documentation of the specific installation, operation and maintenance requirements for the proposed permanent BMP improvements for the project. Accordingly, this Operation and Maintenance Plan (OMP) has been prepared to meet this requirement for the SWQMP. Landscape Areas Many areas of the onsite landscaping for the project have been identified in the SWQMP and on the Grading Plans ("Plans") as either Self -Mitigating Areas or Self -Retaining Areas for purposes of water quality treatment. These landscape areas shall be constructed, operated, and maintained under the following guidelines: 1. The landscape areas, including swales, check dams, and berms, shall be constructed to the grades shown on the approved Plans. The grading shall be done in accordance with the grading specifications for the project. Soils shall not be excessively compacted nor left in a loose condition. 2. The landscape areas shall not be re -graded in the future, nor shall earth or other materials be brought into the landscape areas, in such a manner as to significantly alter the grades or drainage patterns as originally designed and constructed. 3. Landscape areas which are not covered in vegetation, shall be covered with rock, mulch, crushed gravel, or similar materials, in order to avoid bare, unprotected soils. 4. Irrigation of the landscape areas shall be accomplished using Efficient Irrigation Systems as described in the SWQMP, in order to avoid overwatering, watering during rain events, or potential erosion due to excess runoff from broken sprinkler heads or lines. 5. The private drainage system shall be installed per the specifications on the approved Plans, and in the locations and elevations shown on the Plans. Page 1 of 4 6. The private drainage system, including drainage inlets and catch basins, shall not be modified in any manner in the future, so as to alter the types, sizes, locations, or elevations of inlets and catch basins from those which were originally designed and installed. 7. Should any of the drainage system components require repair or replacement in the future, they shall be replaced in the same locations and elevations as originally installed, and with the same or similar types and sizes of drainage system materials and components. 8. The landscape areas shall be inspected on a quarterly basis at minimum, for the health and stability of vegetation. Dead or unhealthy vegetation should be replaced on a regular basis after each inspection. 9. The landscape areas, in particular areas around drainage system inlets and catch basins, shall be regularly maintained to avoid buildup of excess leaves, dead vegetation, or other debris that could hinder or alter the effectiveness of the treatment areas. 10. The landscape areas and drainage system inlets and catch basins should be visually inspected after each rain event producing a half-inch of rain or more, for any signs of erosion or unusual accumulation of sediment or debris. Any required repairs should be completed prior to the next such storm event if possible. 11. The landscape areas should be periodically inspected for positive drainage and/or standing water and vector control. Any areas observed to trap standing water shall be re -graded or repaired as necessary to ensure proper drainage per the original Plan. Permeable Pavement Areas The entire private driveway will be composed of permeable pavement. Specifically, the entire driveway and turnaround area in front of the residence will be constructed with concrete (unit) pavers. These areas have been identified in the SWQMP and on the Plans as Self -Retaining Areas for the purpose of water quality treatment. This permeable pavement area shall be constructed and maintained under the following guidelines: 1. The permeable pavement (unit pavers) shall be installed in the locations and elevations shown and in accordance with the specifications on the approved Plans. Depth of base material (typically gravel, unless otherwise specified) shall be per the approved Plans or pavement specifications, whichever is greater. 2. The permeable pavement shall not be removed or replaced in the future with any impervious surface such as impervious concrete or asphalt, nor shall it be grouted or sealed in any manner which will alter the original pervious characteristics of the pavement (unit pavers). 3. Should any of the permeable pavement (unit pavers) require repair or replacement in the future, it shall be replaced with the same or similar types of materials meeting the original specifications on the Plans. 4. The permeable pavement areas shall be regularly cleared of any weeds, crab grass, or other surface growth, including roots, which could impair the effectiveness of the treatment area by the clogging of voids in the paver units 5. The permeable pavement areas shall be regularly cleared and maintained, to avoid buildup of excess leaves, trash, or other solid debris on the surface that could hinder or alter the effectiveness of the treatment area. 6. Landscape areas adjacent to or draining to the permeable pavement areas shall be kept in good order, planted with no bare soils. Mulch, rocks, or other similar materials should be used to cover any bare soil areas, in order to minimize any potential sources of unwanted sediment on the permeable pavement. 7. The permeable pavement areas shall be regularly cleaned by periodic vacuuming of the surface to remove any accumulated fine materials such as dust, silt, sand, etc. which could over time clog the voids of the unit pavers. Surface cleaning shall be done by use of a Page 2 of 4 vacuum sweeper (Note: simple broom sweepers should not be used) by a person or company qualified to perform this service in accordance with accepted industry standards. Surface cleaning should be performed on a semi-annual basis at a minimum, unless more frequent cleaning is recommended by the manufacturer or installer. 8. The permeable pavement areas should not be pressure washed. 9. The permeable pavement areas should be inspected after each rain event producing a half- inch of rain or more, for any sediment or other fine materials which may have been washed or deposited onto the pavement. Such sediment should be removed prior to the next such rain event. 10. The permeable pavement areas should be observed periodically (at least once per year) during a moderate rain event to check for proper infiltration of runoff into the permeable pavement system (unit pavers). Bioretention Basins Two bioretention basins have been identified in the SWQMP and on the Plans as BMP's for the specific treatment of roof storm runoff. The bioretention basins shall be constructed, operated, and maintained under the following guidelines: 1. The bioretention basins shall be graded and constructed to the sizes and grades shown on the approved Plans. The grading shall be done in accordance with the grading specifications for the project. 2. Native soils at the bottom of the basins should not be excessively compacted or "smeared" during excavation of the basin. Should excessively compacted soil be encountered at the bottom of the basin excavation, the soil should be scarified to a depth of one foot below the bottom of basin, prior to placement of rock and soil within the basins. 3. The bioretention areas shall not be re -graded in the future, not shall earth or other materials be brought into the bioretention areas, which could significantly alter the grades, drainage pattern, and/or water storage function of the basins. 4. No filter fabric or membranes should be installed in the bioretention basins. 5. The rock (gravel drainage layer) shall meet the specifications per the approved Plan, and should be dumped and spread evenly to the specified depth without compaction. 6. The soil media shall meet the specifications per the approved Plan, and shall be dumped and spread to the specified layer depth without being excessively compacted. 7. The bioretention basins shall be planted with grasses, shrubs and/or trees that can withstand short periods of saturation (ie, 12 to 72 hours) as well as long periods of drought. Temporary irrigation may be required during the plant establishment period. 8. Landscaping within the bioretention basins shall be inspected on a semi-annual basis at minimum, for the health and stability of vegetation. Dead or unhealthy vegetation should be replaced on a regular basis after each inspection. 9. The bioretention basins shall be regularly maintained to avoid buildup of excess leaves, dead vegetation, or other trash or debris that could hinder or alter the effectiveness of the basin. The inlet and outlet areas of the basins should be kept clear of any buildup of excess, leaves, vegetation or debris which could impair flows in and out of the basins. 10. The bioretention basins should be visually inspected after each rain event producing a half- inch of rain or more, for any signs of erosion or unusual accumulation of sediment or debris. Any required repairs should be completed prior to the next such storm event if possible. 11. The bioretention basins should be observed periodically (at least once per year) during a moderate rain event to check for general infiltration of runoff into the soil system. Page 3 of 4 Responsible Party The owner of the property shall be the responsible party for implementation of the installation, operation, and maintenance requirements for the described onsite permanent BMP landscape, permeable pavement, and bioretention improvements. All costs associated with the installation, operation and maintenance of the permanent BMP's shall be borne by the owner of the property. These requirements as responsible party shall transfer to the new ownership in the event of sale of the property in the future. Record Keeping The owner of the property, or an assigned representative, shall keep records of the installation, operation, and maintenance of the permanent BMP's as described above, including inspection records. These records shall be maintained for a minimum of five years, and shall be made available to the City, the State Water Resources Control Board, or any other authority regulating storm water discharge, for their inspection upon request at any time during this period.
