CASE <br /> <br /> REPORT TO PLANNING COMMISSION ON <br />TRUNK HIGHWAY #47/SUNWOOD DRIVE CONNECTION <br />By: Steven Jankowski, City Engineer <br /> <br />Background: <br /> <br />At the joint Planning Commission/City Council meeting held on September 19, 1996, <br />Commissioner Deemer requested a cost comparison of the "ESS" curve alignment proposed in <br />the Trunk HighWay ~47 corridor study with the previous alignment which connected Sunwood <br />Drive directly toi 147th Circle. A sketch is attached illustrating both alignments. Below is a <br />rough cost estimate of the construction costs associated with each alignment. <br /> <br />Ess Curve Alignment <br /> <br />1,250 Feet Roadway at $120/ft. $150,000 <br /> <br />Original Alignment <br /> <br />750 Feet Roadway at $75/ft. 56,250 <br />L~u-mp Sum TH 47 RT/Accelerating Lane 15,000 <br />Lump Sum Additional Traffic Signal 150,000 <br /> 221,250 <br /> <br />It should be noted that the Ess curve alignment will have some environmental mitigation costs <br />because of the wetland and for this reason, a higher unit price for the road should be anticipated. <br />However, the cost of an additional traffic signal and the installation of a right turn/acceleration <br />lane offset the longer and more expensive roadway. <br /> <br />Commission Action; <br /> <br />None. <br /> <br />Reviewed by: <br />City Engineer <br /> <br />Copies also distributed to: <br />Mayor and City Council <br />City Administrator <br /> <br />PC: 10/01/96 <br /> <br />~colleen\ccmow\pcase47.do¢ <br /> <br /> <br />
