Minnesota Rule 7030.0040 details noise standards for residential land uses: L10 is the level exceeded 10% or 6 minutes of an hour. L50 is the level exceeded 50% or 30 minutes of an hour. Seventeen noise receptor sites on buildings with direct exposure to noise from 20th Avenue have been evaluated and compared with the Minnesota noise standards for residential land uses. While predicted traffic noise levels exceed the nighttime residential standard at building facades closest to 20th Avenue, exceptions to the rules permit the commercial noise standards if a 30 dBA reduction in the exterior-to-interior sound level can be achieved with appropriate exterior façade design. Staff Comments: th 1.All townhome units in the two (2) buildings adjacent to 20 Avenue (CSAH 54) shall be constructed in such a way that the exterior to interior sound level attenuation is at least 30dB(A) as detailed in the noise study. a.Window areas shall require a minimum STC 30 glazing.
