NOISE ENVIRONMENTAL SETTING External noise sources that could affect the site include traffic noise from Sunol Boulevard and Interstate 680, which are located approxamatly 3,000 feet and 4,000 feet west of the project site, respectively STANDARDS OF SIGNIFICANCE For purposes of this environmental document, an impact is considered significant if the proposed project would: • Result in construction noise levels that do not meet the City of Pleasanton Noise Ordinance; • Result in backyard noise levels exceeding 60 dBA Ldn or indoor noise levels exceeding 45 dBA Ldn. Less Than Significant Potentially Impact With Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact Would the project: a) Exposure of persons to or generation of noise levels in X excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b) Exposure of persons to or generation of excessive X ground borne vibration or ground borne noise levels? c) A substantial permanent increase in ambient noise X levels in the project vicinity above levels existing without the project? d) A substantial temporary or periodic increase in X ambient noise levels in the project vicinity above levels existing without the project? e) For a project located within an airport land use plan X or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?

The proposal would change the NSSP land use designation of the approximately 1.01-acre northern portion of the site from PUD-Agriculture to PUD-Medium Density Residential. The PUD-Medium Density Residential land use category allows a maximum density of 3.5 dwelling units per acre. The proposed density of the PUD-Medium Density Residential portion of the site would be 3.0 dwelling units per acre. The remaining 2.27-acre southern portion of the site would retain the PUD-Agriculture land use 33 as a less-than-significant impact. c) Sycamore Creek runs through the southern portion of the site. In order to determine whether the proposed project would affect the water flow in Sycamore Creek, hydrology studies were prepared by LandTech, Inc7. The studies found that the proposed development would result in slight increase in surface water flow into Sycamore Creek, but the increase is not considered to be significant and would not result in substantial erosion or siltation on- or 31 event landslides, lateral spreading, subsidence, liquefaction and collapse on the project site.
