construction be conducted outside the bird-breeding season (February through August). In an event that the construction cannot be scheduled outside the breeding season, a wildlife biologist should conduct a breeding bird survey within 30 days of the onset of construction to determine if nesting birds are present. In the event that nesting birds are identified to be present, further mitigation may include establishing buffers no less than 50 feet from active nests until young birds have fledged the nest. Staff has added condition to address these issues. During the site assessment period, Congdon's tarplant (Hermizonia parryi ssp. Congdonii) was found at a fcw scattered locations within and adjacent to the proposed construction area. Although not a state or federal listed species, Congdon tarplant is afforded a special status listing by CNPS. To minimize the impact to this plant, the report recommends that seed collection and seed storage until it is time to reseed. Staff has included a condition to address this issue. Access/Circulation and Traffic Access to the proposed development would be from a private drive off of Dublin Canyon Road. The private court has a hammerhead design to accommodate fire truck maneuvering. The applicant is required to pay for the pro rata sharc of improvement on Dublin Canyon Road. The City's Traffic Engineer has reviewed the proposed three-lot development. Based on the amount of traffic that may be generated from the proposed development, the City Traffic Engineer requires the applicant pay for the required traffic mitigation fee. No traffic report is required. Noise Study At the request of staff, a noise study was performed by Thorburn Associates over a 24-hour period. The report found the sources of noise impacting the subject site are from Interstate 580, BART, and daily traffic on Dublin Canyon Road and Laurel Creek Drive. The report finds that the outdoor noise at the proposed residential house sites would be conditionally acceptable (per General Plan) at 63-67 dBA Ldn, and that the indoor noise at the site would be at 45 Ldn, a normally acceptable category. The report further finds that the exterior noise would be reduced due to the proposed construction measures. Stucco finish over plywood sheathing, and insulation in the wall cavity would improve the noise impact. Additionally, window glazing and weather-stripping at doors would also help reducc thc noise Icvel. The report concludcd that the proposed construction at the proposed lots would conform to the Gencral Plan. Case No. PUD-44 Planning Commission Page - 8-
