See attached improvement plans. I. Routine Maintenance Activities Types of pervious pavement include pervious concrete, porous asphalt, and permeable interlocking concrete pavement (PICP), concrete grid pavers, and plastic reinforcement grid pavers. The principal maintenance objective is to prevent sediment buildup and clogging, which reduces infiltration capacity and pollutant removal efficiency. Routine maintenance activities, and the frequency at which they will be conducted, are shown in Table 1. Table 1 Routine Maintenance Activities for Pervious Paving Areas No. Maintenance Task Frequency of Task 1 Check for sediment and debris accumulation. Prevent soil from Two to four times annually washing or blowing onto the pavement. Do not store sand, soil, mulch or other landscaping materials on pervious pavement surfaces. 2 Conduct preventative surface cleaning, using commercially available Two to four times annually regenerative air or vacuum sweepers, to remove sediment and debris. 3 Inspect for any signs of pavement failure. Repair any surface Two to four times annually deformations or broken pavers. Replace missing joint filler in PICP. 4 Check for standing water on the pavement surface within 30 minutes Two to four times annually after a storm event. 5 Inspect underdrain outlets and cleanouts, preferably before the wet Two to four times annually season. Remove trash/debris. 6 Remove sediment and debris accumulation on pervious pavement. Two to four times annually 7 Remove weeds. Mow vegetation in grid pavements (such as turf As needed block) as needed. 8 Perform restorative surface cleaning with a vacuum sweeper, and/or As needed reconstruction of part of the pervious surface to restore surface permeability as needed. Replenish aggregate in PICP joints or grids as needed after restorative surface cleaning. 9 Power washing with simultaneous vacuuming also can be used to As needed restore surface infiltration to highly clogged areas of pervious concrete, porous asphalt or PICP, but is not recommended for grid pavements. 10 Inspect pervious paving area using the attached inspection checklist. Quarterly or as needed Page 1 Pervious Pavement Maintenance Plan Date of Inspection: Property Address: 11226 Bubb Rd. - Lot B Treatment Measure No.: Use of Pesticides Do not use pesticides or other chemical applications to control weeds or unwanted growth near pavement or between pavers.

See attached improvement plans. I. Routine Maintenance Activities Types of pervious pavement include pervious concrete, porous asphalt, and permeable interlocking concrete pavement (PICP), concrete grid pavers, and plastic reinforcement grid pavers. The principal maintenance objective is to prevent sediment buildup and clogging, which reduces infiltration capacity and pollutant removal efficiency. Routine maintenance activities, and the frequency at which they will be conducted, are shown in Table 1. Table 1 Routine Maintenance Activities for Pervious Paving Areas No. Maintenance Task Frequency of Task 1 Check for sediment and debris accumulation. Prevent soil from Two to four times annually washing or blowing onto the pavement. Do not store sand, soil, mulch or other landscaping materials on pervious pavement surfaces. 2 Conduct preventative surface cleaning, using commercially available Two to four times annually regenerative air or vacuum sweepers, to remove sediment and debris. 3 Inspect for any signs of pavement failure. Repair any surface Two to four times annually deformations or broken pavers. Replace missing joint filler in PICP. 4 Check for standing water on the pavement surface within 30 minutes Two to four times annually after a storm event. 5 Inspect underdrain outlets and cleanouts, preferably before the wet Two to four times annually season. Remove trash/debris. 6 Remove sediment and debris accumulation on pervious pavement. Two to four times annually 7 Remove weeds. Mow vegetation in grid pavements (such as turf As needed block) as needed. 8 Perform restorative surface cleaning with a vacuum sweeper, and/or As needed reconstruction of part of the pervious surface to restore surface permeability as needed. Replenish aggregate in PICP joints or grids as needed after restorative surface cleaning. 9 Power washing with simultaneous vacuuming also can be used to As needed restore surface infiltration to highly clogged areas of pervious concrete, porous asphalt or PICP, but is not recommended for grid pavements. 10 Inspect pervious paving area using the attached inspection checklist. Quarterly or as needed Page 1 Pervious Pavement Maintenance Plan Date of Inspection: Property Address: 11226 Bubb Rd. - Lot C Treatment Measure No.: Use of Pesticides Do not use pesticides or other chemical applications to control weeds or unwanted growth near pavement or between pavers. III. Vector Control Standing water shall not remain in the treatment measures for more than five days, to prevent mosquito generation. Should any mosquito issues arise, contact the Santa Clara Valley Vector Control District (District). Mosquito larvicides shall be applied only when absolutely necessary, as indicated by the District, and then only by a licensed professional or contractor. Contact information for the District is provided below.

Replace vegetation with plants with similar growth. Conditions within unit provide mosquito breeding habitat. Property Owner: Type of Inspection: Monthly Pre -wet season After heavy runoff (1" or greater) End of wet season Other Maintenance completed and if needed Needed? maintenance was not conducted, (Y/N) Date note when it will be done) Results Expected When Maintenance is Performed Trash & debris removed from area drains & swales to be disposed of properly. Material removed so that there is no clogging or blockage. Material is disposed of properly. Obstructions and sediments removed so that water flows freely and disperses over a wide area. Obstructions and sediment are disposed of properly Vegetation is healthy and attractive in appearance, Treat vegetation using preventative and low -toxic methods. Potential vectors abated by filing holes in the ground around the unit and by insuring that there are no areas where water stands longer than 5 days. 5.Mosquitos Mosquito larvae present evident in standing water 6.On-site Storm Evidence of Water Facilities sedimentation in the storm drain system. 7. Off -site Street Evidence of Facilities sedimentation in the blo-retention area. 9. Miscellaneous Any condition not covered above that needs attention in order for the bio- retention and infiltration areas, Contact Santa Clara County Vector Control Services District if mosquitos present Material removed so that there is no clogging or blockage. Material is disposed of properly. Material removed so that there Is no clogging or blockage. Material is disposed of properly. Meet the design specifications,
