The pedestrian crossing location will need to be looked at carefully due to the proposed
<br /> northbound free right turn movement to County.Road F that will conflict with the pedestrian
<br /> crossing. -
<br /> Noise
<br /> As a part of the Noise Advisory Committee (NAC), Mn/DOT analyzed the noise walls for
<br /> the entire project. While some walls were determined to be reasonable (reduce the noise
<br /> by a minimum of 5dBA), no walls were determined to be cost effective. The City is
<br /> interested in the consideration of a 20' high noise barrier along the north side of the west
<br /> bound C/D road. The total cost of this wall is approximately $1,525,000. Mn/DOT is _
<br /> willing to participate up to $3250 per decibel per benefiting property. This means that the
<br /> City could request that Mn/DOT construct this wall. In doing so, Mn/DOT would contribute
<br /> approximately$1,050,000 and the City would be required to pay the remaining cost,
<br /> approximately$475,000. These costs are based on the most cost effective wall
<br /> construction_ No costs associated with design or construction would be attributed to the
<br /> city.
<br /> Landscape Plan
<br /> Mn/DOT is working on establishing a landscape plan for the project area. The landscaping
<br /> would occur a couple of years after the completion of the roadway construction.
<br /> Proiect Benefits
<br /> • Public Safety: In the last 3 years, there have been 426 crashes on 1-694 from
<br /> Lexington Avenue to TH 10, including 3 fatalities/serious injury crashes and 423 injury
<br /> and personal damage crashes.
<br /> • With the proposed project, the traveling public, including Arden Hills residents and
<br /> employers in Arden Hills can expect:
<br /> o A reduction in the crash rate (number of crashes per million vehicle miles
<br /> traveled (MVM))from the existing level of 4.5 to a typical freeway section in the
<br /> metro area of 1.0. Reduction in crashes will reduce traffic volumes using local
<br /> streets during these events
<br /> o A reduction in the severity rate (number of crashes, weighted according to their
<br /> injury type per MVM)from the existing level of 5.6 to a typical freeway section in
<br /> the metro area of 1.2.
