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 into a single-family residence, in accordance with applications for a Development Review MDRA09-024WCF and Grading Permit Number G10-0008, 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": A bioretention basin located in the northeastern corner of the property, a trench drain filters within the driveway, and a Filterra Bioretention Unit System located along the westerly property line as shown in Exhibit "B". The precise location(s) and extent of the BMPs are indicated on the approved grading plans on file with CITY's Development Services Department as G10-0008. 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". Because additional impervious area may require the addition of or alteration of storm water management facilities and strategies, no additional impervious area or 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 ACTIVITIES, it is understood that CITY shall be deemed to be acting as the agent of the OWNER SWFMA (GIO-0008) 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. 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.

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.

SPECIFICATIONS BioSorb Hydrocarbon Booms I. Specifications Coverage: When properly installed BioSorb Hydrocarbon Booms provide sufficient contact time, at rated flows, of passing contaminate water. The BioSorb material will capture and retain all hydrocarbons that are absorbed into its physical structure. The BioSorb material is made of a proprietary polymer based beads. The material is usually contained within booms or pouches. The booms and pouches are made of 100% polyester netted fabric with sieve openings of 1mm, open area ratio is approximately 67%. These booms and pouches can be used in an array of different treatment devices, including but not limited to flume filters, trench drain filters, downspout filters, catch basin inserts, water polishing units, and hydrodynamic separators. Non -Corrosive Materials: Both the BioSorb material and the boom and pouch netting are non -corrosive materials. Durability: The BioSorb and netting material have been chosen for their proven durability. The BioSorb and netting are of sufficient strength to support water, sediment, and debris loads when the media is at maximum absorption capacity; with no slippage, breaking, or tearing. The BioSorb has been tested through rigorous flow and loading conditions. Oil Absorbent Media: The BioSorb has been proven to absorb up to 180% of it weight within 300 second contact time. At this absorption percent the physical increase in the size of the BioSorb granules is not more than 50%. This minimal increase in physical size in relation to the high absorption capacity is due to the BioSorb material being highly porous with large amounts of void areas within its structure. The flow through the media boom, assuming 50% blockage is to be greater than the physical flow through the filter device. This information can obtained from a Bio Clean representative, if the BioSorb Boom is used within a Bio Clean Filter System. Pollutant Removal Efficiency: The BioSorb is designed to capture high levels of Hydrocarbons including but not limited to oils & grease, gasoline, diesel, and PAHs. The granule nature of the material, with approximately 2000mm sized granules also has the physical ability to block and filter trash and litter, grass and foliage, and sediments. Replacement: Removal and replacement of the booms containing the absorbent media is simple. Remove boom from filtration system. Replace with new boom of equal size. II. Installation Installation: The BioSorb Boom will be securely installed in the filter device, with contact surfaces sufficiently joined together so that no filter bypass can occur at low flow. Installation Notes: 1. Bio Clean Environmental Services, Inc. BioSorb Boom shall be installed pursuant to the manufacturer's recommendations and the details on this sheet. 2. BioSorb Boom shall provide coverage of the incoming stormwater at the specified flow rate, based upon application and the device in which the boom is used in. 3. The BioSorb Boom is installed by removing the old boom and replacing it with a new boom. P 0 Box 869 Oceanside CA 92049 (760) 433-7640 • Fax (760) 433-3176 www.BioCleanEnvironmental.net III. Maintenance Maintenance: The BioSorb boom is made to be used for period that is determined by the amount of hydrocarbon loading present in each installation. The Boom is easily removable from most filer devices. At each cleaning, new hydrocarbon booms should be installed by placing in the filter if deemed necessary by service crews. Maintenance Notes: 1. Bio Clean Environmental Services Inc. recommends cleaning and debris removal maintenance a minimum of four times per year, and replacement of BioSorb Booms a minimum of twice per year. 2. Following maintenance and/or inspection, the maintenance operator shall prepare a maintenance/inspection record. The record shall include any maintenance activities performed, amount and description of debris collected, and condition of filter. 3. The owner shall retain the maintenance/inspection record for a minimum of five years from the date of maintenance. These records shall be made available to the governing municipality for inspection upon request at any time. 4. For maintenance and cleaning remove old boom and replace with new boom. Where possible the maintenance should be performed from the ground surface. Note: entry into an underground stormwater vault such as an inlet vault requires certification in confined space training. 5. Remove all trash, debris, organics, and sediments collected by the filter prior to removal and replacement of the BioSorb Boom. 6. Evaluation of the BioSorb Boom shall be performed at each cleaning. If the boom is filled with hydrocarbons and oils it should be replaced. The color of the boom material is the best indication of the amount of hydrocarbons present in the BioSorb material. The darker the color the more impacted the BioSorb material. 7. Transport all debris, trash, organics and sediments to approved facility for disposal in accordance with local and state requirements. 8. There are several methods for disposing of used BioSorb oil absorbing polymers. BioSorb has been tested according to the EPA's Toxicity Characteristic Leaching Procedure ("TCLP") and found to be none leaching.

Filterra is a specially engineered stormwater treatment system incorporating high performance biofiltration media to remove pollutants from stormwater runoff. The system's biota (vegetation and soil microorganisms) then further breakdown and absorb captured pollutants. All components of the system work together to provide a sustainable long-term solution for treating stormwater runoff. The Filterra system has been delivered to you with protection in place to resist intrusion of construction related sediment which can contaminate the biofiltration media and result in inadequate system performance. These protection devices are intended as a best practice and cannot fully prevent contamination. It is the purchaser's responsibility to provide adequate measures to prevent construction related runoff from entering the Filterra system. Included with your purchase is Activation of the Filterra system by the manufacturer as well as a 1-year warranty from delivery of the system and 1-year of routine maintenance (mulch replacement, debris removal, and pruning of vegetation) up to twice during the first year after activation. Design and Installation Each project presents different scopes for the use of Filterra systems. Information and help may be provided to the design engineer during the planning process. Correct Filterra box sizing (by rainfall region) is essential to predict pollutant removal rates for a given area. The engineer shall submit calculations for approval by the local jurisdiction. The contractor is responsible for the correct installation of Filterra units as shown in approved plans. A comprehensive installation manual is available at www.ContechES.com. Activation Overview Activation of the Filterra system is a procedure completed by the manufacturer to place the system into working condition. This involves the following items: • Removal of construction runoff protection devices • Planting of the system's vegetation • Placement of pretreatment mulch layer using mulch certified for use in Filterra systems. Activation MUST be provided by the manufacturer to ensure proper site conditions are met for Activation, proper installation of the vegetation, and use of pretreatment mulch certified for use in Filterra systems. 4 www.ContechES.com/filterra j 800-338-1 122 Minimum Requirements The minimum requirements for Filterra Activation are as follows: 1 .The site landscaping must be fully stabilized, i.e. full landscaping installed and some grass cover I not just straw and seed) ) is required to reduce sediment transport. Construction debris and materials should be removed from surrounding area. 2.Final paving must be completed. Final paving ensures that paving materials will not enter and contaminate the Filterra system during the paving process, and that the plant will receive runoff from the drainage area, assistingwith plant survival for the Filterra system. 3.Filterra throat opening should be at least 4" in order to ensure adequate capacity for inflow and debris. 4"MIN CLEAR THROAT OPENING CAST -IN -PLACE GUTTER AND THROAT OPENING (BY CONTRACTOR PER LOCAL STANDARDS) THROAT PROTECTION DEVICE DO NOT REMOVE - LEAVE IN PLACE UNTIL SITE IS STABILIZED AND FILTERRA IS ACTIVATED An Activation Checklist is included on page 12 to ensure proper conditions are met for Contech to perform the Activation services. A charge of $500.00 will be invoiced for each Activation visit requested by Customer where Contech determines that the site does not meet the conditions required for Activation. www.ContechES.com/filterra 1800-338-1 122 5 Filterra Plant Selection Overview A Plant List has been enclosed with this packet highlighting recommended plants for Filterra systems in your area. Keep in mind that plants are subject to availability due to seasonality and required minimum size for the Filterra system. Plants installed in the Filterra system are container plants (max 15 gallon) from nursery stock and will be immature in height and spread at Activation. It is the responsibility of the owner to provide adequate irrigation when necessary to the plant of the Filterra system. The "Planting Requirements for Filterra Systems" document is included as an appendix and discusses proper selection and care of the plants within Filterra systems. Warranty Overview Refer to the Contech Engineered Solutions LLC Stormwater Treatment System LIMITED WARRANTY for further information. The following conditions may void the Filterra system's warranty and waive the manufacturer provided Activation and Maintenance services: • Unauthorized activation or performance of any of the items listed in the activation overview • Any tampering, modifications or damage to the Filterra system or runoff protection devices • Removal of any Filterra system components • Failure to prevent construction related runoff from entering the Filterra system • Failure to properly store and protect any Filterra components (including media and underdrain stone) that may be shipped separately from the vault Routine Maintenance Guidelines With proper routine maintenance, the biofiltration media within the Filterra system should last as long as traditional bioretention media. Routine maintenance is included by the manufacturer on all Filterra systems for the first year after activation. This includes a maximum of 2 visits to remove debris, replace pretreatment mulch, and prune the vegetation. More information is provided in the Operations and Maintenance Guidelines. Some Filterra systems also contain pretreatment or outlet bays. Depending on site pollutant loading, these bays may require periodic removal of debris, however this is not included in the first year of maintenance, and would likely not be required within the first year of operation. These services, as well as routine maintenance outside of the included first year, can be provided by certified maintenance providers listed on the Contech website. Training can also be provided to other stormwater maintenance or landscape providers. 6 www.ContechES.com/filterra 1800-338-1122 Why Maintain? All stormwater treatment systems require maintenance for effective operation. This necessity is often incorporated in your property's permitting process as a legally binding BMP maintenance agreement. Other reasons to maintain are: • Avoiding legal challenges fromyour jurisdiction's maintenance enforcement program. • Prolonging the expected lifespan of your Filterra media. • Avoiding more costly media replacement. • Helping reduce pollutant loads leaving your property. Simple maintenance of the Filterra is required to continue effective pollutant removal from stormwater runoff before discharge into downstream waters. This procedure will also extend the longevity of the living biofilter system. The unit will recycle and accumulate pollutants within the biomass, but is also subjected to other materials entering the inlet. This may include trash, silt and leaves etc. which will be contained above the mulch layer. Too much silt may inhibit the Filterra's flow rate, which is the reason for site stabilization before activation. Regular replacement of the mulch stops accumulation of such sediment. When to Maintain? Contech includes a 1-year maintenance plan with each system purchase. Annual included maintenance consists of a maximum of two (2) scheduled visits. Additional maintenance may be necessary depending on sediment and trash loading (by Owner or at additional cost). The start of the maintenance plan begins when the system is activated. Maintenance visits are scheduled seasonally; the spring visit aims to clean up after winter loads including salts and sands while the fall visit helps the system by removing excessive leaf litter. It has been found that in regions which receive between 30-50 inches of annual rainfall, (2) two visits are generally required; regions with less rainfall often only require (1) one visit per annum. Varying land uses can affect maintenance frequency; e.g. some fast food restaurants require more frequent trash removal. Contributing drainage areas which are subject to new development wherein the recommended erosion and sediment control measures have not been implemented may require additional maintenance visits. Some sites may be subjected to extreme sediment or trash loads, requiring more frequent maintenance visits. This is the reason for detailed notes of maintenance actions per unit, helping the Supplier and Owner predict future maintenance frequencies, reflecting individual site conditions. Owners must promptly notify the (maintenance) Supplier of any damage to the plant(s), which constitute(s) an integral part of the bioretention technology. Owners should also advise other landscape or maintenance contractors to leave all maintenance to the Supplier (i.e. no pruning or fertilizing) during the first year. www.ContechES.com/filterra 1800-338-1 122 7 Exclusion of Services Clean up. due to major contamination such. as oils, chemicals, toxic:spills, etc. will result in additional costs and are not covered :under the Supplier maintenance contract. Should a major contamination event occur the Owner must: block off the -outlet pipe of the Filterra (where the cleaned. runoff drains to, such as drop inlet) and block off the throat of the Filterra. The -Supplier should be informed immediately. Maintenance Visit Summary Each maintenance visit consists of the following simple tasks (detailed -instructions below) 1..- Inspection. of Filterra .and surrounding area. 2. Removal of tree -grate and erosion control stones 3. Removal of debris, trash .and mulch 4. Mulch replacement 5. Plant -health -evaluation -and -pruning or replacement as necessary .6..

Do -not lift plant(s).:by trunk .as :this can break roots•and cause -soil to fall off.=Extract the root ball in a horizontal position and support it to prevent it from breaking .apart. Alternatively the -pot can be -cut away -to minimize root ball disturbance. • Remove any excess soil from. above the -root flare after removing:plant(s) from container. • Excavate a hole with a diameter 4" greater than the root ball, gently place the plant(s). • If :plant(s) .have any circling roots from being -pot- bound, gently tease them loose without breaking them. •- :If root ball has.a root: mat :on the: bottom, it should be shaved off with a knife just above the :mat line. • -Plant the tree/shrub/grass with the:top of the .root: ball 1 "-above surrounding media to allow for settling. • All plants should have the main- stem centered in the tree grate (where applicable) upon completion of installation. • With all-trees/shrubs, remove dead, diseased, crossed/rubbing, sharply crotched branches or branches growing excessively long or:in wrong.di:rection compared to :majority of branches. • To prevent transplant shock (especially if planting takes place in the hot season), it may be necessary -to prune some of th.e.foliage .to. compensate.for reduced root uptake capacity. This is accomplished by pruning away some.of the smaller. :secondary -branches or a. main scaffold branch .if there are too many. Too much foliage relative to the root ball can :dehydrate . and damage -the plant. • Plant staking may be required. www.ContechES.com/filterra 1 800-338-1 122 13 Mulch Installation • Only mulch that has been meeting Contech Engineered Solutions' mulch specifications can be used in the Filterra system. • Mulch must be applied to a depth of 3" evenly over the surface of the media. Irrigation Requirements • Each Filterra system must receive adequate irrigation to ensure survival of the living system during periods of drier weather. • Irrigation sources include rainfall runoff from downspouts and/or gutter flow, applied water through the tree grate or in some cases from an irrigation system with emitters installed during construction. • At Activation: Apply about one (cool climates) to two (warm climates) gallons of water per inch of trunk diameter over the root ball. • During Establishment: In common with all plants, each Filterra plant will require more frequent watering during the establishment period. One inch of applied water per week for the first three months is recommended for cooler climates (2 to 3 inches for warmer climates). If the system is receiving rainfall runoff from the drainage area, then irrigation may not be needed. Inspection of the soil moisture content can be evaluated by gently brushing aside the mulch layer and feeling the soil. Be sure to replace the mulch when the assessment is complete. Irrigate as needed**. • Established Plants: Established plants have fully;developed root systems and can access the entire water column in the media. Therefore irrigation is less frequent but requires more applied water when performed. For a mature system assume 3.5 inches of available water within the media matrix. Irrigation demand can be estimated as 1" of irrigation demand per week. Therefore if dry periods exceed 3 weeks, irrigation may be required. It is also important to recognize that plants which are exposed to windy areas and reflected heat from paved surfaces may need more frequent irrigation. Long term care should develop a history which is more site specific. ** Five gallons per square yard approximates 1 inch of water Therefore for a 6' by 6' Filterra approximately 20-60 gallons of water is needed. To ensure even distribution of water it needs to be evenly sprinkled over the entire surface of the filter bed, with special attention to make sure the root ball is completely wetted. NOTE: if needed, measure the time it takes to fill a five gallon bucket to estimate the applied water flow rate then calculate the time needed to irrigate the Filterra. For example, if the flow rate of the sprinkler is 5 gallons/minute then it would take 12 minutes to irrigate a 6' by 6' filter.
