EXHIBIT C Bioretention Area Maintenance Plan Date of Inspection: Property Address: 2002 Davis Street San Leandro CA Treatment Measure No.: II. Prohibitions The use of pesticides and quick release fertilizers is strongly discouraged. For the purposes of stormwater treatment measure maintenance and function, it is anticipated that non -chemical controls (i.e., biological, physical, and cultural controls) will be adequate to address any pest problems. Proper and timely maintenance, as described in this plan, should serve to reduce the potential for pest establishment. To avoid the need for pesticides or quick release fertilizers, follow the principles of integrated pest management (IPM): 1. Employ non -chemical controls (biological, physical and cultural controls) before using chemicals to treat a pest problem. 2. Prune plants properly and at the appropriate time of year. 3. Provide adequate irrigation for landscape plants. Do not over water. 4. Limit fertilizer use unless soil testing indicates a deficiency. Slow -release or organic fertilizer is strongly preferred. Check with municipality for specific requirements and prohibitions. 5. Pest control should avoid harming non -target organisms, or negatively affecting air and water quality and public health. Apply chemical controls only when monitoring indicates that preventative and non -chemical methods are not keeping pests below acceptable levels. When pesticides are required, apply the least toxic and the least persistent pesticide that will provide adequate pest control. Do not apply pesticides on a prescheduled basis. 6. Sweep up spilled fertilizer and pesticides. Do not wash away or bury such spills. 7. Do not over apply pesticide. Spray only where the infestation exists. Follow the manufacturer's instructions for mixing and applying materials. 8. Only licensed, trained pesticide applicators shall apply pesticides. 9. Apply pesticides at the appropriate time to maximize their effectiveness and minimize the likelihood of discharging pesticides into runoff. With the exception of pre -emergent pesticides, avoid application if rain is expected. 10. Unwanted/unused pesticides shall be disposed as hazardous waste. Standing water shall not remain in the treatment measures for more than four days, to prevent mosquito generation. Should any mosquito issues arise, contact the Alameda County Mosquito Abatement District (ACMAD), as needed for assistance. In Albany, contact the Alameda County Vector Control Services District (ACVCSD). Mosquito larvicides shall be applied only when absolutely necessary, as indicated by the ACMAD or ACVCSD, and then only by a licensed professional or contractor. Contact information for ACMAD and ACVCSD is provided below. III.
