2. Construction Dust Control <br />Future development within the Specific Plan Area will result in dust and other <br />particulates during site preparation and construction activities. In order to avoid adverse <br />impacts on air quality, the following measures shall be implemented: <br />3. <br />a. During the construction period , all active unpaved construction areas shall <br />be watered at least twice daily or treated with non-toxic soil stabilizers in <br />order to avoid dust. Exposed stockpiles of dirt or sand shall be enclosed, <br />covered, watered twice daily, or treated with non-toxic soil binders. <br />b. If soil material is carried on public or private roads , such roads shall be <br />swept daily with water sweepers to control dust, where applicable. <br />c. In graded construction areas, permanent replacement vegetation shall be <br />planted as quickly as possible , properly irrigated, and maintained in <br />healthy growing condition. Graded areas that remain inactive for ten days <br />or more during the rainy season (October 1 to April 1) without permanent <br />replanting shall be hydroseeded or stabilized . <br />d. All trucks hauling excavated materials shall be covered with tarpaulins or <br />other effective covers. <br />e. All unpaved access roads, parking areas, and staging areas at construction <br />sites shall be rocked, watered three times daily , or covered with non-toxic <br />soil stabilizers. <br />f. Traffic speed on unpaved roads shall be limited to 15 miles per hour. <br />g. Reactive organic gas (ROG) emissions from adhesives, clean-up solvents , <br />paint, and asphalt paving materials used during project construction shall <br />be reduced by using materials with a low ROG content, in compliance <br />with Bay Area Air Quality Management District standards. <br />Geoloiical Reguirements Relatine to Construction <br />Due to the unique geological conditions presented by the Plan Area, a series of <br />site-specific studies and mitigation measures for future development will be necessary. <br />These include the following: <br />a . All structures and constructed slopes shall be designed in accordance with <br />the most recent Uniform Building Code as modified by the California <br />Code of Regulations. A soils and geotechnical report shall be prepared <br />for each individual development (unless otherwise approved by the City <br />49
