29. The developer shall submit a dust control plan as part of the improvement plans. This plan shall include the following measures in order to avoid adverse impacts on air quality during construction: a. All active unpaved construction areas shall be watered at least twice daily or treated with non-toxic soil stabilizers in order to avoid dust. Exposed stockpiles of dirt or sand shall be enclosed, covered, watered twice daily, or treated with non-toxic soil binders. b. If soil material is carried on public or private roads, such roads shall be swept daily with water sweepers to control dust, where applicable. c. In graded construction areas, permanent replacement vegetation shall be planted as quickly as possible, properly irrigated, and maintained in healthy growing condition. Graded areas that remain inactive for ten days or more during the rainy season (October I to April I ) without permanent replanting shall be hydroseeded or stabilized. d. All trucks hauling excavated materials shall be covered with tarpaulins or other effective covers. e. All unpaved access roads, parking areas, and staging areas at construction sites shall be covered with rock, watered three times daily, or covered with non-toxic soil stabilizers. f. Traffic speed on unpaved roads shall be limited to 15 miles per hour. g. Reactive organic gas (ROG) emissions from adhesives, clean-up solvents, paint, and asphalt paving materials used during project construction shall be reduced by using materials with a low ROG content, in compliance with Bay Area Air Quality Management District standards. 30. The applicant is responsible for implementing the following measures during all construction phases of the project: a. Gather all construction debris on a regular basis and place it in a dumpster or other container which is emptied or removed an a weekly basis. When appropriate, use tarps on the ground to collect fallen debris or splatters that could contribute to storm water runoff pollution. b. Remove all dirt, gravel, rubbish, refuse, and green waste from the street pavement and storm drains adjoining the site. Limit construction access routes onto the site and place gravel on them. Do not drive vehicles and equipment off paved or graveled areas during wet weather. Broom sweep the street pavement adjoining the project site on a daily basis. Scrape caked-on mud and dirt from these areas before sweeping. c. Install filter materials (such as sandbags, filter fabric, etc.) at the storm drain inlet nearest the downstream side of the project site in order to retain any debris or dirt flowing in the storm drain system. Maintain and/or replace filter materials to ensure effectiveness and to prevent street flooding. d. Create a contained and covered area on the site for the storage of bags, cement, paints, oils, fertilizers, pesticides, or other materials used on the site that have the potential of being discharged into the storm drain system through being windblown or in the event of a material spill. e. Never clean machinery, equipment, tools, brushes, or rinse containers into a street, gutter, or storm drain. f. Ensure that concrete/gunite supply trucks or concrete/plaster operations do not discharge wash water into street, gutters, or storm drains. 31. The applicant shall comply with the recommendations of the tree report prepared by Hortscience dated August 1999. No tree trimming or pruning other than that specified in the tree report shall occur. The applicant shall arrange for the horticultural consultant to conduct a field inspection prior to issuance of grading permits to ensure that all recommendations have been properly implemented. The consultant shall certify in writing that such recommendations have been followed. No trees shall be removed other than those
