impacts to these receptors are anticipated to be minimal. Following the complete build -out of the site, air pollution will be generated by traffic moving along the local and regional street system. Dust is expected to be generated by on -site construction equipment during times of construction. Dust generation will be minimized by enforcing best management practices during construction along with any other applicable permits required by the City of Lino Lakes. Practices that may be enforced include: 1) minimizing the periods and extent of areas being exposed or graded; 2) watering construction areas and haul roads during periods of high winds or high levels of construction activity; 3) minimizing the use of vehicles on unpaved surfaces; and 4) covering and/or spraying material piles and truck loads. No substantial odor sources are expected within the proposed development site. Noise will be generated during the construction of the public improvements (e.g. roads, sewer, water) and during the construction of residential and commercial/office buildings in the development. A variety of equipment, such as scrapers, loaders, dozers, backhoes, and trucks, will be implemented to construct the proposed improvements. These types of equipment have average noise levels in the range of 74 to 91 dBA at 50 -feet away from the source. A number of factors can affect noise attenuation; however, it can be generally estimated that a certain sound will decrease by 6 db for each doubling of the distance from the poise source. City ordinance regulates the daytime hours of construction to minimize noise impacts to adjacent areas. Increased traffic noise is another element that was considered for the proposed development. However, the associated increases in traffic volumes are not anticipated to cause a substantial change in noise levels. Traffic noise increases must be 3 decibels or greater in order to be detectable by the average human ear. A 3- decibel increase occurs when traffic volumes double (100 percent increase). The only sensitive noise receptors near the proposed development are a small group of existing residential properties located south of the site. Noise mitigation is not proposed at this time because construction noise will be temporary and all City and County roads in the area are exempt from state noise standards. The only nearby road that is not exempt from State noise standards is I -35W. Noise levels along the local roadways are not anticipated to exceed State noise standards, nor are they anticipated to be greater than noise levels that are commonly experienced within a residential and commercial area. Furthermore, adequate building setbacks and acoustical site planning techniques may be further considered in the placement and arrangement of buildings to shield more sensitive land uses from noise impacts. 25.
