<br /> <br />Red Morton Community Park Sports Lighting Initial Study <br />City of Redwood City 33 June 2015 <br />Standard Measures: BAAQMD has prepared lists of standard construction dust control measures <br />to ensure construction impacts remain at levels that are less than significant, and recommends they be <br />implemented by all construction projects.10 The following construction practices would be <br />implemented to the extent feasible during construction: <br /> <br /> All exposed surfaces shall be watered two times per day. <br /> All haul trucks transporting soil, sand, or other loose material off-site shall be <br />covered. <br /> All visible mud or dirt track-out onto adjacent public roads shall be removed using <br />wet power vacuum street sweepers at least once per day. The use of dry power <br />sweeping is prohibited. <br /> All excavation, grading, and/or demolition activities shall be suspended when average <br />wind speeds exceed 20 mph. <br /> If vegetative ground cover is present prior to construction, it shall be restored as soon <br />as possible. <br /> Sandbags or other erosion control measures shall be installed to prevent silt runoff to <br />public roadways. <br /> A publicly visible sign with the telephone number and person to contact at the <br />District regarding dust complaints shall be posted. This person shall respond and <br />take corrective action within 48 hours. The Air District’s phone number shall also be <br />visible to ensure compliance with applicable regulations. <br /> <br />Construction activities can also be a source of TACs. BAAQMD developed screening thresholds for <br />health risks associated with construction TACs. The screening thresholds state that the minimum <br />development that could result in significant TAC impacts would be the construction of five single <br />family residences at a distance of 95 feet from the nearest sensitive receptors. Although a few of the <br />proposed light standards would be located within 95 feet of sensitive receptors on Myrtle Street, the <br />intensity and duration of construction activities associated with installation of the proposed sports <br />lighting is significantly less what would be required for five single family residences. For these <br />reasons, impacts associated with construction TACs would be less than significant. <br /> <br />4.3.4 Conclusion <br /> <br />The proposed project would not result in significant long-term air quality impacts. Implementation <br />of the standard measures described above would reduce short-term air quality impacts associated <br />with project construction to a less than significant level.
