ÐP <br />suburban/urban ambient sound levels and therefore could cause a temporary increase above the <br />threshold discussed above. For reference, typical suburban/urban background sound levels are <br />20 <br />commonly on the order of 45 to 55 dBA during daytime hours and lower during nighttime hours. <br />Because sound pressure levels from construction of a new hotel, which was needed due to a STR ban, <br />have the potential to cause a temporary increase above the noise level threshold, more analysis is <br />needed to evaluate specific impacts and potential mitigation. While construction may be exempt from <br />the noise ordinance during daytime hours, the table below shows that the construction could have a <br />significant noise impact on the community. <br />Furthermore, if any nighttime construction activity is needed for the hotel, the noise levels below show <br />that threshold for nighttime work in the noise ordinance would be exceeded. <br />Table 7.
