2. Control and prevent the discharge of all potential pollutants, including solid wastes, paints, concrete, petroleum products, chemicals, washwater or sediments, and non-stormwater discharges to storm drains and watercourses. 3. Use sediment controls or filtration to remove sediment from dewatering effluent. 4. Avoid cleaning, fueling, or maintaining vehicles on-site, except in a designated area in which runoff is contained and treated. 5. Delineate clearing limits, easements, setbacks, sensitive or critical areas, buffer zones, trees, and drainage courses with field markers. 6. Protect adjacent properties and undisturbed areas from construction impacts using vegetative buffer strips, sediment barriers or filters, dikes, mulching, or other measures as appropriate. 7. Perform clearing and earth moving activities only during dry weather. 8. Limit and time applications of pesticides and fertilizers to prevent polluted runoff. 9. Limit construction access routes and stabilize designated access points. 10. Avoid tracking dirt or other materials off-site; clean off-site paved areas and sidewalks using dry sweeping methods. [COA][HUD EA] 68. Indoor Noise Standards — The following measures shall be incorporated into the project in order to meet the residential indoor noise standard. 1. Windows and doors of bedrooms and living/dining rooms in the proposed building with direct line -of -sight to Jefferson Avenue should have a Sound Transmission Class (STC) rating of 36 or greater. These windows and doors, in combination with the exterior wall construction, would achieve an outdoor - to -indoor composite noise reduction of 37 to 38 decibels with the windows and doors closed and would maintain interior noise levels below 45 dBA DNL with an adequate margin of safety. 2. All units throughout the site should be mechanically ventilated so that windows can be kept closed at the occupant's discretion to control noise intrusion indoors. 3. A noise study must be approved by the City's Building Inspection Division prior to the issuance of a building permit. Noise studies consistent with the requirements of the California Building Code shall be conducted for proposed new multifamily residential projects to identify noise reduction measures necessary to achieve compatibility with City Noise Element guidelines (55 ATTY/RESO.0027/PC RESO 612 JEFFERSON REV: 03-21-17 PR Page 20 of 22
