P. Since the impervious area of the site appears to exceed 2,500 square feet, the <br />site is considered as small project per Alameda County C.3 Stormwater <br />Technical Guidance. As per Appendix L "Site Design Requirements for Small <br />Projects", the project must implement at least one of the following site design <br />measures and show them on the drawings: <br />a) Direct roof runoff into cisterns or rain barrels for use. <br />b) Direct roof runoff onto vegetated areas. <br />c) Direct runoff from sidewalks, walkways, and/or patios onto vegetated areas. <br />d) Direct runoff from driveways/uncovered parking lots onto vegetated areas. <br />e) Construct sidewalks, walkways, and/or patios with permeable surfaces. <br />f) Construct bike lanes, driveways, and/or uncovered parking lots with <br />permeable surfaces. <br />Q. The applicant shall reduce storm water pollution by implementing the following <br />pollution source control measures: <br />a) Structures shall be designed to discourage the occurrence and entry of pests <br />into buildings, thus minimizing the need for pesticides. The trash area shall <br />be separated from the rest of the building by concrete or masonry walls so <br />that pests that gain access to the area are less likely to access the rest of the <br />building. <br />b) All storm drains shall be marked "NO DUMPING, DRAINS TO BAY", as per <br />the City of San Leandro Standard Plan Dwg. No. 204, Case 3101. <br />c) All on-site storm drains shall be inspected and, if necessary, cleaned at least <br />twice a year immediately prior to the rainy season. <br />d) Sidewalks and parking lots shall be swept regularly to minimize the <br />accumulation of litter and debris. Steam cleaning or low volume pressure <br />washing may be performed only after pre -cleaning using dry methods, spot <br />cleaning and recovery in stained areas and removal of all mobile pollutants. <br />Debris resulting from pressure washing shall be trapped and collected to <br />prevent entry into the storm drain system. Wash water containing any soap, <br />cleaning agent or degreaser shall not be discharged to the storm drain. <br />e) Interior floor drains (if any) shall not be connected to the storm drain system. <br />f) Air conditioning condensate shall be directed to landscaped areas. Any air <br />conditioning condensate that discharges to land without flowing to a storm <br />drain may be subject to the requirements of the State Water Resources <br />Control Board's (SWRCB) Statewide General Waste Discharge <br />Requirements (WDRs) for Discharges to Land with a Low Threat to Water <br />Quality. <br />g) Landscaping shall be designed to minimize irrigation and runoff, promote <br />surface infiltration where appropriate, and minimize the use of fertilizers and <br />pesticides that can contribute to storm water pollution. <br />h) Where feasible, landscaping shall be designed and operated to treat storm <br />water runoff by incorporating elements that collect, detain, and infiltrate <br />runoff. In areas that provide detention of water, plans that are tolerant of <br />saturated soil conditions and prolonged exposure to water shall be specified. <br />Agreement to Conditions August I, 2019 <br />PLN 18-0091 Page 8 of 15 <br />
