070 11. The noisiest construction operations will be arranged to occur together in the construction program to avoid continuing periods of greater annoyance. Rationale The predicted noise levels are based upon the most current analytical methods, using projected traffic volumes and roadway geometry as a basis for determining existing and future noise contours and the height of solid barriers needed to reduce predicted noise levels to less than the FHWA significance threshold. The use of solid barriers to effectively attenuate noise has been proven in many different locations, and is often the most feasible method, when large spatial separations between the noise source and the sensitive receptor cannot be provided. The installation of solid walls along the widened street right- of-way can be readily accomplished, using standard construction techniques. The City's Noise Ordinance limits the permissible hours of construction to workday and Saturday periods when the noise environment along Bristol Street is most pronounced and the construction activities will, therefore, be somewhat masked within the ambient noise levels. Proper maintenance of construction equipment and vehicles and sensitive staging of equipment and activity rises with respect to nearby residential uses, can reasonably be expected to further minimize the short-term construction noise to an acceptable level. Housing Displacement Significant Effects Acquisition of needed right-of-way and completion of the proposed improvements would result in the removal of 163 housing units (including both single and multi-family units). Removal of these housing units would displace approximately 538 residents (assuming an average household size of 3.3) who would need comparable, decent, safe and sanitary replacement housing in a nearby neighborhood of their choice. A proper and adequate residential relocation program will be complicated by the mixed Hispanic, Asian, and Caucasian ethnicity of the displaced households and by the expected high percentage of lower income households involved. As discussed in the Draft Relocation Study, the City will retain Spanish and Vietnamese- speaking relocation agents and interpreters to facilitate relocation of these affected minority groups.
