b. During non -operational evening hours, all exterior parking lot lighting levels shall be designed such that they do not exceed 10 foot candles. 19. In accordance with measure AQ -2.1, the applicant shall implement the following mitigation measures during all construction phases to reduce impacts associated with construction dust to the extent feasible, as determined by the City Engineer. These measures shall be incorporated into the construction documents describing procedures and specifications for contractors to follow. a. Water all active construction areas at least twice daily. b. Cover all trucks hauling soil, sand, and other loose materials to or from the Project Area or require all trucks to maintain at least two feet of freeboard. c. Pave, apply water three times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas and staging areas at construction sites. d. Sweep daily (with water sweepers) all paved access roads, parking areas and staging areas at construction sites. e. Sweep streets daily (with water sweepers) if visible soil material is carried onto adjacent public streets. f. Hydroseed or apply (non-toxic) soil stabilizers to inactive construction areas (previously graded areas inactive for ten days or more). g. Enclose, cover, water twice daily or apply (non-toxic) soil binders to exposed stockpiles (dirt, sand, etc.). h. Limit traffic speeds on unpaved roads to 15 mph. i. Install sandbags or other erosion control measures to prevent silt runoff to public roadways. j. Replant vegetation in distributed areas as quickly as possible. k. Suspend excavation and grading activities to the extent feasible when instantaneous wind gusts exceed 25 mph. I. Limit, to the extent feasible, the number of areas adjacent to residences subject to excavation, grading and other construction activity at any one time. 20. In accordance with measure BIO -5.1, prior to the beginning of mass grading, between February 15 and August 15, including grading for major infrastructure improvements, an avian nesting survey shall be conducted of all habitat within 350 feet of any grading or earthmoving activity. The survey shall be conducted by a qualified biologist, as determined by the City, and occur no more than 21 days prior to disturbance. If no active nests are found, no further action is required. If active nests for special status avian species or raptor nests are found within the construction footprint, construction activities shall be delayed within a minimum 500 -foot buffer zone surrounding active raptor nests and a minimum 250 -foot buffer zone surrounding nests of other special status avian species until the young have fledged. This buffer zone shall not extend beyond the Staples Ranch site. The appropriate buffer can be modified by the City in consultation with qualified biologists and the California Department of Fish and Wildlife (CDFW). No action other than avoidance shall be taken without CDFW consultation. Completion of the nesting cycle shall be determined by a qualified ornithologist or biologist, as determined by the City.
