Brooks Trust U/A dated September 25, 2007, (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 as a single - family residence, in accordance with applications for Minor Development Review Application 13 -032, and Grading Permit No. G12 -0015, 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 ": Two bioretention basins and multiple self - retaining and self - treating landscaping areas all as shown on the approved grading plans. The precise location(s) and extent of the BMPs are indicated on the approved grading plans and within the Water Quality Technical Report for the Brooks Residence on file with CITY's Development Services Department as G12 -0015. 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. 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.

DESCPOL- 02 / 26 /92 -I rc Exhibit "B" Maintenance Plan A Maintenance Plan is a Irving document and field conditions may require modifications to the Maintenance Plan. The responsible party "RP" may change, mechanical equipment may be replaced, and additional maintenance procedures may be needed. Throughout these changes, the maintenance plan must be kept up-to -date. Updates may be transmitted to the City at any time. However, at a minimum, updates to the maintenance plan must accompany the annual inspection report The stormwater NPDES Permit requires the City to verify all treatment and flow - control facilities are adequately maintained. Facilities installed as part of your project will be verified for effectiveness and proper performance. The City will also verify the ongoing function of stormwater management features that are not treatment or flow control facilities, such as permeable pavements and limitations on impervious area. I. Introduction The project site is located at the west end of Del Poniente Road and is approximately 3.7 acres in size. The development includes a single family house located near the north - center of the site. The proposed grading generally follows the existing topography and drainage will continue to discharge points along the north property line and at the northwest comer of the property where there are existing concrete lined drainage ditches. The drainage improvements at the northwest comer discharge to Del Poniente Road through an existing concrete curb drain. Two bioretention areas which provide for water quality and hydromodification are located in the northwest quadrant of the property. They are shown and detailed on the project grading plans and sized for hydromodification in the project WQTR. Features in addition to the bioretention areas and spillways that will have an impact on runoff, including runoff erosion potential are the use of open -joint pavers, vegetated swales, self - retaining areas and landscaping throughout the site. The use of pavers for some of the hardscape areas onsite maximizes infiltration by allowing runoff to soak into site soil through the openings between the paving stones and the gravel base. This will keep more runoff onsite in the soil and decrease the runoff discharge during any storm event. Vegetated swales give runoff a longer contact time for infiltration and decrease runoff velocity protecting against downstream erosion as water must make a slower path through grass or groundcover. Draining impervious roof areas to self- retaining areas provides slight ponding in a storm event to retain runoff, slow it and allow for some infiltration. These features were chosen because they work to keep runoff onsite as much as possible instead of allowing storm flows (including a portion of loo -year storm event flows) to exit the site and also because they slow down runoff that does leave the site and protect downstream areas from erosion. The facilities that require inspection and maintenance by the RP are designated on the WQTR Exhibit. A reduced copy of the exhibit is included in Section I at the end of the maintenance plan. 11. Responsibility for Maintenance "RP" Updated contact information must be provided to the City immediately whenever a property is sold and whenever designated individuals change. RP /Property Owner. Dave Brooks RP Phone Number.' 858 945 -1616 The RP should include copies of all inspection and maintenance records for a minimum of 5 years and any reports in Section 11 at the end of the maintenance plan. The RP may hire or designate another person to perform the inspection and maintenance, but the responsibility for filing the form with the City and the ultimate responsibility for the information included on the form lies with the RP. Ill. Summary of Drainage Areas and Stormwater Facilities A. Drainage Areas i. An exhibit, showing pervious and impervious areas is included in Section I at the end of the maintenance plan. The main impervious areas are the roof, which drains to the surrounding landscaping and self-retaining areas, and the concrete driveway which drains to the two bioretention areas. Pervious areas, not including the slopes, also drain to the self - retaining areas or bioretention areas, as shown on the exhibit. The landscaped slopes around the site are designed to drain directly offsite. If they were to drain onsite, the bioretention areas would need to be much larger. it is important to maintain the drainage patterns designed for the project and not change them without acquiring the proper permits and approvals. ii. The exhibit also includes a description of each drainage area and how flow is routed to each to and from the pervious and impervious areas of the site.' B. Treatment and Flow - Control Facilities i. An exhibit, showing the location, size and type of each facility is included in Section I at the end of the maintenance plan. The exhibit also includes a description of each drainage area and how flow is routed to each facility. ii. In the case of your self- retaining areas generally located in the front and north side yard, runoff from roof downspouts and the yard itself flows on the surface to a low spot or depressed area. A grated inlet is located at the low spot but is elevated a few inches about the surrounding ground so that water will pond before cresting over the inlet and continuing offsite. Keeping the grate clean and free of leaves or debris makes sure that water will not pond deeper than a few inches and will not sit stagnant for longer than 48 hours. It is important for the depressed area around the grate to remain because that holds the ponding water and allows the self- retaining area to function as a water quality feature. The self- retaining areas drain through the grates and into the onsite storm drain which brings runoff down to the edge of the graded area of the lot where flow is allowed to continue on the surface to the north. iii. The bioretention areas are located along the north side of the driveway towards the northwest comer. Runoff from the driveway and a few of the grated inlets to the south of the house drains through the onsite storm drain system to the bioretention areas. The bioretention areas function by holding water and allowing it to infiltrate and also allowing the water to react with the engineered soil mixture and the plant life within the area. It is important that the plants in the bioretention area are maintained since they have been chosen for that location and a specific purpose. If plantings are dying, a professional landscape architect should be contacted for direction. iv. All of the storm drain inlets and outlets shown and listed on the exhibit and the as- built drawings are a part of the functionality of your stormwater system. They must be kept free from any blockages, repaired or replaced as necessary to make sure that site drainage makes its way safely away from the house and to the facilities that were designed to clean and discharge the water. Iv. Maintenance Schedule A. Maintenance Schedule for each facility with specific requirements for Routine inspection and maintenance —The best time to complete routine inspections and maintenance of your stormwater facilities is at the same time that you inspect you irrigation system. Once a month, bi- monthly or at least every season, is a good time to briefly turn on the irrigation and do a walk through inspection to make sure pipes and sprinklers aren't broken or leaking. While you are doing a walk through inspection, keep your eyes open for blocked grates or ponding water, areas where soil or rock has washed away, plants that do not look healthy, etc. If the issue is corrected early, it will be less expensive than replacing broken items on a yearly basis. ii. Annual inspection and maintenance - The City requires that you file an annual inspection and maintenance report. iii. Inspection and maintenance after major storms — Erosion and debris /sediment problems will be most likely and noticeable after a major storm. Clearing any blockages or stabilizing any areas where soil is washing out after a major storm guarantees that your stormwater system will be able to function at full capacity immediately afterwards and will also make sure that lateral damages such as mosquito breeding and soil saturation near the house foundation do not occur.
