(4) sweep streets daily with water sweepers if visible soil material is carried onto adjacent public streets; (5) hydroseed or apply (non-toxic) soil stabilizers to inactive construction azeas (previously-graded areas inactive for 10 days or more); (6) enclose, cover, water twice daily or apply (non-toxic) soil binders to exposed stockpiles (dirt, sand, etc.); (7) limit traffic speeds on unpaved roads to 15 mph; (8) install sandbags nr other erosion control measures to prevent silt runoff to public roadways; (9) replant vegetation in disturbed areas as quickly as possible; (10) install wheel washers for all exiting trucks, or wash off the tires or tracks of all trucks and equipment leaving the site; (11) install windbreaks, or plant trees/vegetative wind breaks at windward side(s) of construction azeas; and (12) suspend excavation and grading activity when winds (instantaneous gusts) exceed 25 mph, and limit the azea subject to excavation, grading and other construction activity at any one time. b. Condition _ of the PUD and Specific Plan Air Quality Policy 2 require adherence [o dust control Best Management Practices to control construction-related dust emissions during al] phases of construction. These BMPs must be approved by the City Engineer and followed at all times during grading and construction operations. These practices may include watering exposed surfaces at ]east twice a day, with a possibility of more frequent watering when wind speeds exceed 15 mph; covering of stockpiled earth; and covering of trucks hauling dirt if windy conditions prevail. J. Noise 1. Impact L2. Proposed commercial/office land uses within the Project area would be exposed to exterior noise levels in excess of a Ldn of 70 dB. Mitigation Measure: Measure L2. Incorporate sound-reducing building components in commercial and office portions of the Project that are exposed to exterior noise levels exceeding 70 dB Ldn Finding: Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect identified in the Final EIR to a less than significant level. Facts in Support of Finding: The impact will be avoided or reduced based on the following: a. Construction practices are available which can achieve [he 45 dB Ldn interior standard for commercial office buildings in the noisiest areas of the site: b. The PUD and Specific Plan Noise Attenuation Policy 2, Guideline 2.6, require that interior noise levels in commercial and office structures shall not exceed 35
