<br /> <br /> <br />In the HIA, air quality is <br />measured by exposure to both <br />point-source pollutants (like <br />businesses that create <br />emissions) and major roads <br />(such as interstates) which <br />have been shown to reduce air <br />quality. Ramsey's goal is to <br />improve air quality by <br />preserving existing tree canopy <br />and adding to canopy cover <br />whEllnever possible, especially <br />along Highway 10. <br /> <br />Air Quality <br />HlA THReSHO~D <br /> <br />The first Incllcator to describe the extent of ilir q\,Jallty within the Threshold <br />Analysis Assessment Is the "distance from major roads for residential uses and <br />uses occupied by chlldren.1I All residential areas, schools, daycare facilities, <br />playgrounds, and sports fields should be more than 200 meters from any <br />"major road" to obtail1 any points in this indicator. <br /> <br />Another air quality indicator is the existence of polluting businesses within the <br />community. Points are awarded on an all-or-nothing basis, and result in 6 <br />points if there are no polluting uses OR the sources are regulated locally as well <br />as by state or federal governments. <br /> <br />The final Indicator Is air quality mitigation, as defined by the existence of <br />significant tree canopy cover, with focus on areas around major roads. In order <br />to achieve any points In this category, at least 50% of "major roads" mU$t be <br />lined with streettree$ OR If a tree preservation plan Is In plClce. <br /> <br />CURRENT .ACHIEVEMENT <br /> <br />(TOTAL POINTS= .1.2) <br /> <br />Distance from a Major Road-9 points <br />Currently, there are no "major roads", as defined by having more than 40,000 <br />AADT, in Ramsey. Therefore, Ramsey has obtained all points In this category. <br /> <br />However, Highway 10 could reach these traffic levels by 2030. A buffer of 200 <br />meters and 500 meters reveals that there are no daycares or schools within <br />close proximity to Highway 10. However, there is one after-school program <br />geared towards teens and three sports field at one commercial location within <br />the buffer,area. There Is a substantial amount of residential land uses within <br />each buffer (see Figure #2), There are approximately 190 residential parcels <br />within 200 meters, mostly townhouse units. Within 500 meters, there are <br />approximately 525 residential pan::als or lots. HOWever, there are thousands of <br />housing units planl'1edwithln the 500 mlilter buffer of Highway 10, Most of the <br />community's dElnmer development is concentrated near the major <br />transportation corridors In the Town Center area. Also, there are four park <br />areas within the buffer, but only one Is developed as an active park at this time. <br />The Mississippi River West Regional Park is planned to be an active park, but Is <br />not at this time. This park has significant canopy cover, which may mitigate <br />some of the negative effects on air quality caused by proximity to Highway 10. <br /> <br />5 <br /> <br />-104- <br />
