Measurement Site 1 was located in the front yard of a single - family <br />residence. The residence lies mid -block on Bristol Street, 200 feet <br />north of Santa Clara Avenue and is affected by changes in noise level <br />due to the signal at this intersection. The measurement was taken 15 <br />feet from the Bristol Street right -of -way and 5 feet from the front <br />entryway of the house. This residence is representative of 10 other <br />houses in the vicinity. <br />Measurement Site 2 was located in the playground area of the Santiago <br />Elementary School. The playground lies adjacent to Bristol Street and <br />has full street exposure. There is an existing chain link fence separating <br />the school grounds from the roadway. This fence provides no noise <br />attenuation and is broken at two ends of the property for pedestrian <br />access. The closest classroom to Bristol Street lies 275 feet from the <br />Bristol Street right -of -way. <br />Measurement Site 3 was selected at a muiti- family detached (MFD) <br />dwelling complex in a common recreational area. The site was adjacent <br />to a gazebo in an outdoor activity area, between two of the front <br />residential units and 39 feet west of the Bristol Street right -of -way. A <br />chain link fence, gated for pedestrian access, exists at the right -of -way. <br />This noise measurement is representative of the noise level at 33 <br />residences on Bristol Street between Santa Clara Avenue and <br />Seventeenth Street. <br />Measurement Site 4 was taken on the Rancho Santiago Community <br />College Campus adjacent to the auditorium. The site was 70 feet from <br />the Bristol right -of -way. A three -foot block wall at the right -of -way <br />provides some noise attenuation but allows complete line of sight <br />exposure to truck exhaust stacks. This block wall is also broken directly <br />in front of the measurement site to allow for pedestrian access. The <br />noise level measured at this site also reflects volumes on Seventeenth ` <br />Street adjacent to this intersection. _. <br />Measurement Site 5 was taken in the front yard of a mid -block single - <br />family dwelling (SFD) at five feet from the Bristol Street right -of -way. <br />This front yard area has full exposure to the roadway. The noise level <br />at this residence is expected to be representative of noise levels at 16 <br />similar residences along Bristol Street in the project vicinity. <br />Measurement Site 6 was selected at an SFD that is a "worst case" <br />receptor in this area. The site lies three feet from the Bristol Street <br />right -of -way at a point 80 feet south of Seventh Street. The <br />measurement was taken adjacent to the front porch. This outdoor <br />activity area has full exposure to Bristol Street. <br />Measurement Site 7 was taken adjacent to a four -unit, multi - family - <br />attached (MFA) dwelling at 114 Bristol Street. The residence lies at <br />111-22 <br />75C -93 <br />
