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 applications for a Building Permit B20-2092, which are 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 Trash Facilities which are identified as "Best Management Practices" or "BMPs": Nine (9) FloGard+ catch basin filters and two (2) BioClean curb inlet 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 B20-2092. 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". SWTFMA (B20-2092/TA21-003) Because additional impervious area may require the addition of or alteration of storm water 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 Trash 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.

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 upon reasonable notice to OWNER, to enter upon any part of said area as may be necessary or convenient for such purposes.

The intent of the regulations is to ensure that the systems, on a continuing basis, efficiently remove pollutants from stormwater runoff thereby preventing pollution of the nation's water resources. These specifications apply to the FloGard+Plus® Catch Basin Insert Filter. RECOMMENDED FREQUENCY OF SERVICE: Drainage Protection Systems (DPS) recommends that installed FloGard+Plus Catch Basin Insert Filters be serviced on a recurring basis. Ultimately, the frequency depends on the amount of runoff, pollutant loading and interference from debris (leaves, vegetation, cans, paper, etc.); however, it is recommended that each installation be serviced a minimum of three times per year, with a change of filter medium once per year. DPS technicians are available to do an on-site evaluation, upon request. RECOMMENDED TIMING OF SERVICE: DPS guidelines for the timing of service are as follows: 1. For areas with a definite rainy season: Prior to, during and following the rainy season. 2. For areas subject to year-round rainfall: On a recurring basis (at least three times per year). 3. For areas with winter snow and summer rain: Prior to and just after the snow season and during the summer rain season. 4. For installed devices not subject to the elements (wash racks, parking garages, etc.): On a recurring basis (no less than three times per year). SERVICE PROCEDURES: 1. The catch basin grate shall be removed and set to one side. The catch basin shall be visually inspected for defects and possible illegal dumping. If illegal dumping has occurred, the proper authorities and property owner representative shall be notified as soon as practicable. 2. Using an industrial vacuum, the collected materials shall be removed from the liner. (Note: DPS uses a truck -mounted vacuum for servicing FloGard+Plus catch basin inserts). 3. When all of the collected materials have been removed, the filter medium pouches shall be removed by unsnapping the tether from the D -ring and set to one side. The filter liner, gaskets, stainless steel frame and mounting brackets, etc., shall be inspected for continued serviceability. Minor damage or defects found shall be corrected on -the -spot and a notation made on the Maintenance Record. More extensive deficiencies that affect the efficiency of the filter (torn liner, etc.), if approved by the customer representative, will be corrected and an invoice submitted to the representative along with the Maintenance Record. 4. The filter medium pouches shall be inspected for defects and continued serviceability and replaced as necessary, and the pouch tethers re -attached to the liner's D -ring. 5. The grate shall be replaced. REPLACEMENT AND DISPOSAL OF EXPOSED FILTER MEDIUM AND COLLECTED DEBRIS The frequency of filter medium exchange will be in accordance with the existing DPS -Customer Maintenance Contract. DPS recommends that the medium be changed at least once per year. During the appropriate service, or if so determined by the service technician during a non-scheduled service, the filter medium will be replaced with new material. Once the exposed pouches and debris have been removed, DPS has possession and must dispose of it in accordance with local, state and federal agency requirements. DPS also has the capability of servicing all manner of storm drain filters, catch basin inserts and catch basins without inserts, underground oil/water separators, stormwater interceptors and other such devices. All DPS personnel are highly qualified technicians and are confined -space trained and certified.

The filter is available in several configurations including trash full capture, multi-level screening, Kraken membrane filter and media filter variations. This manual covers maintenance procedures of the trash full capture and multi-level screening configurations. A supplemental manual is available for the Kraken and media filter variations. The innovative trough & weir system is mounted along the curb face and directs incoming stormwater toward the filter basket which is positioned "directly" under the manhole access opening regardless of its location in the catch basin. This innovative design allows the filter to be cleaned from finish surface without access into the catch basin, therefore drastically reducing maintenance time and eliminating confined space entry. The filter has a lifting handle allowing for the filter to be removed easily through the manhole. The weir also folds up to allow for unimpeded access into the basin for routine maintenance or pipe jetting. As with all stormwater BMPs, inspection and maintenance on the Curb Inlet Filter is necessary. Stormwater regulations require BMPs be inspected and maintained to ensure they are operating as designed to allow for effective pollutant removal and provide protection to receiving water bodies. It is recommended that inspections be performed multiple times during the first year to assess site- specific loading conditions. This is recommended because pollutant loading can vary greatly from site to site. Variables such as nearby soil erosion or construction sites, winter sanding of roads, amount of daily traffic and land use can increase pollutant loading on the system. The first year of inspections can be used to set inspection and maintenance intervals for subsequent years. Without appropriate maintenance a BMP can exceed its storage capacity which can negatively affect its continued performance in removing and retaining captured pollutants. 1 ( Page A Forterra Company Inspection Equipment Following is a list of equipment to allow for simple and effective inspection of the Curb Inlet Filter: • Bio Clean Environmental Inspection Form (contained within this manual). • Manhole hook or appropriate tools to remove access hatches and covers. • Appropriate traffic control signage and procedures. • Protective clothing and eye protection. • Note: entering a confined space requires appropriate safety and certification. It is generally not required for routine inspections or maintenance of the system. Inspection Steps The core to any successful stormwater BMP maintenance program is routine inspections. The inspection steps required on the Curb Inlet Fitler are quick and easy. As mentioned above the first year should be seen as the maintenance interval establishment phase. During the first year more frequent inspections should occur in order to gather loading data and maintenance requirements for that specific site. This information can be used to establish a base for long-term inspection and maintenance interval requirements. The Curb Inlet Filter can be inspected though visual observation without entry into the catch basin. All necessary pre -inspection steps must be carried out before inspection occurs, such as safety measures to protect the inspector and nearby pedestrians from any dangers associated with an open access hatch or manhole. Once the manhole has been safely opened the inspection process can proceed: • Prepare the inspection form by writing in the necessary information including project name, location, date & time, unit number and other info (see inspection form). • Observe the inside of the catch basin through the manhole. If minimal light is available and vision into the unit is impaired utilize a flashlight to see inside the catch basin. • Look for any out of the ordinary obstructions in the catch basin, trough, weir, filter basket, basin floor our outlet pipe. Write down any observations on the inspection form. • Through observation and/or digital photographs estimate the amount of trash, foliage and sediment accumulated inside the filter basket. Record this information on the inspection form. • Observe the condition and color of the hydrocarbon boom. Record this information on the inspection form. 21 Page A Forterra Company • Finalize inspection report for analysis by the maintenance manager to determine if maintenance is required. Maintenance Indicators Based upon observations made during inspection, maintenance of the system may be required based on the following indicators: • Missing or damaged internal components. • Obstructions in the trough, weir, filter basket or catch basin. • Excessive accumulation of trash, foliage and sediment in the filter basket and/or trough and weir sections. Maintenance is required when the basket is greater than half -full. • The following chart shows the 50% and 100% storage capacity of each filter height: Model Filter Basket Diameter (in) Filter Basket Height (in) 50% Storage Capacity (cu ft) 100% Storage Capacity (cu ft) BC -CURB -30 18 30 2.21 4.42 BC -CURB -24 18 24 1.77 3.53 BC -CURB -18 18 18 1.33 2.65 BC -CURB -12 18 12 0.88 1.77 Maintenance Equipment It is recommended that a vacuum truck be utilized to minimize the time required to maintain the Curb Inlet Filter though it can easily cleaned by hand: • Bio Clean Environmental Maintenance Form (contained in O&M Manual). • Manhole hook or appropriate tools to access hatches and covers. • Appropriate safety signage and procedures. • Protective clothing and eye protection. • Note: entering a confined space requires appropriate safety and certification. It is generally not required for routine maintenance of the system. Small or large vacuum truck (with pressure washer attachment preferred). Maintenance Procedures It is recommended that maintenance occurs at least two days after the most recent rain event to allow debris and sediments to dry out. Maintaining the system while flows are still entering it will increase the time and complexity required for maintenance. Cleaning of the Curb Inlet Filter can be performed from finish surface without entry into catch basin utilizing a vacuum truck. Some unique Wage d 1� A Forterra Company and custom configurations may create conditions which would require entry for some or all of the maintenance procedures. Once all safety measures have been set up cleaning of the Curb Inlet Filter can proceed as followed: • Remove all manhole cover or access hatches (traffic control and safety measures to be completed prior). • Using an extension on a vacuum truck position the hose over the opened manhole or hatch opening. Insert the vacuum hose down into the filter basket and suck out trash, foliage and sediment. A pressure wash is recommended and will assist in spraying of any debris stuck on the side or bottom of the filter basket. If the filter basket is full, trash, sediment, and debris will accumulate inside the trough and weir sections of the system. Once the filter basket is clean power wash the weir and trough pushing these debris into the filter basket (leave the hose in the filter basket during this process so entering debris will be sucked out). Power wash off the trough, weir, debris screen, and filter basket sides and bottom. • Next remove the hydrocarbon boom that is attached to the inside of the filter basket. The hydrocarbon boom is fastened to rails on two opposite sides of the basket (vertical rails). Assess the color and condition of the boom using the following information in the next bullet point. If replacement is required install and fasten on a new hydrocarbon boom. Booms can be ordered directly from the manufacturer. • Follow is a replacement indication color chart for the hydrocarbon booms: Excellent Condition Good Condition Minimal Capacity Replacement Required • The last step is to close up and replace the manhole or hatch and remove all traffic control. • All removed debris and pollutants shall be disposed of following local and state requirements. • Disposal requirements for recovered pollutants may vary depending on local guidelines. In most areas the sediment, once dewatered, can be disposed of in a sanitary landfill. It is not anticipated that the sediment would be classified as hazardous waste. • In the case of damaged components, replacement parts can be ordered from the manufacturer. Hydrocarbon booms can also be ordered directly from the manufacturer as previously noted. 41 Page Maintenance Sequence Remove manhole cover and set up vacuum truck to clean the filter basket.
