Ponderosa Homes - LehmanlSelway Property - Environmental Checklist d) As a result of project construction, there will be a temporary increase in noise due to construction activities. However, the hours of construction will be limited to minimize any impact to sur- rounding land uses. Therefore, this would be a less-than-signijicant-impact. e) Figure VIII-4, Future (2010) Noise Contours, of the P1easanton General Plan', forecasts an am- bient noise level for the site of between 55 dBA and 60 dBA for aircraft generated noise based upon its distance - five miles - from the Livermore Municipal Airport. This noise level is con- sidered to be "Normally Acceptable" for Residential, Hotels, and Motels by the Pleasanton Gen- eral Plan (Table VIII-3, Land Use Compatibility for Community Noise Environment. However, the Livermore Airport Master Plan anticipates that aircraft activity and associated noise levels are projected to increase7. Studies have indicated that people will be generally annoyed by air- craft noise at a lower average sound level than for other transportation sources - aircraft noise at a given LON is more annoying than traffic noise at the same level. The Pleasanton General Plan generally discourages residential developments where the exterior noise level due to aircraft noise sources exceeds 55 dBA LON. However, the site is between the 55 dBA/60 dBA noise con- tours. The Pleasanton General Plan will allow the project with the stipulation that the dwellings' interior noise levels are controlled so that the maximum noise levels do not exceed 50 dBA LON in bedrooms or 55 dBA LON in other rooms. Therefore, this would be a less-than-signijicant- impact. f) The subject site is located within approximately five miles from the Livermore Municipal Air- port. This distance will not likely create significant noise impacts. Common construction prac- tices can mitigate noise levels to a less-than-signijicant-impact. 8. POPULATION AND HOUSING Environmental Setting Over the past ten years, there have been several development projects proposed in this area, including for constructed developments in the Stoneridge Drive Specific Plan Area to the north and northeast and the Ironwood development by Ponderosa Homes to the southeast. The Lehman-Selway properties were also part of the 34.5-acre prezoning approved by the City Council on Aprill, 1997 to the PUD - LDR District reflecting the underlying land use designation of the Pleasanton General Plan. The site and sur- rounding area has been considered for some time as a desired location for single-family residential de- velopment. Build out of the area does not constitute direct or indirect growth inducing impacts for the City of Pleasant on. Standards of Significance For purposes of this environmental document, an impact is considered significant if the proposed project would: . Induce substantial growth that is inconsistent with the approved land use plans in place; . Displace affordable housing. PUD-50 and PTR-5572 Page 26 of 36 June 7, 2006
