Road Advisory Minutes-March 17, 2008 2 islands and surrounding pavement would need replacing, however; the central roundabout area could be used and an estimated 75% of the approach islands could be saved. The estimated cost savings is $205,000 assuming a 3% inflation rate through 2018. Due to the close proximity of the bridge future profile grades remain uncertain. The roundabout profile grades will need to be modified to match the future county 17 and 52nd Avenue profile. Based on 2018 dollars the total estimated savings is $270,000. The 2018 estimated savings of $270,000 requires an additional expenditure in 2008 of $190,000 thus bringing the net savings to $15,000 in 2018 dollars. The estimated cost to construct a traditional intersection and signalize it is $175,000, with a projected annual electrical expense of $360 and maintenance cost of $850. Mr. Wagner questioned whether there would be an advantage to constructing a single- lane roundabout taking into consideration that in the future the intersection may lay within the jurisdiction of either Horace or West Fargo. He was informed that this will not be an issue for some time. Mr. Berndt said some of the right of way has been obtained and additional right of way will be obtained in the near future. Mr. Suhr asked if a single- lane roundabout would be feasible for large equipment. Mr. Lane said that an inside area would allow for wider and longer vehicles. He stated the location of the roundabout would not change if the bridge were to be reconstructed although the grade may change and a portion of the road may need to be readjusted. Mr. Berndt said the bridge redesign could be set by the elevation of the roundabout. Mr. Vanyo is concerned with public opinion if the intersection were to be reconstructed in 10 years thus wasting taxpayer dollars. He also questioned if the 2008 budget is able to accommodate this project. Mr. Berndt assured committee members the project would be within the budget. Mr. Pawluk asked if West Fargo is aware of this project. Mr. Berndt has contacted the West Fargo city engineer. Mr. Wagner asked about public notification. Mr. Berndt stated if the committee agrees to proceed, a public meeting will be held in Horace. Mr. Pawluk asked if the committee were to choose option #3 what time frame would there be until signalization is needed. Mr. Lane responded that at the present growth rate approximately three to five years. Mr. Wagner expressed safety concerns with rush hour traffic. Mr. Pawluk asked if the above cost estimates included right of way costs. Mr. Berndt said that option #2 included an additional $40,000 for right of way. The balance of the right of way required for any of the options was not included in the above listed estimates. Right of way in the northeast quadrant of the intersection as been acquired and negotiations are in progress for the remaining quadrants. MOTION, passed Mr. Wagner moved and Mr. Berndt seconded to recommend Option #2: to construct a roundabout in permanent location for $241,000 + $190,000=$431,000. Discussion: Mr. Saewert asked for clarification of the additional $190,000. Mr. Berndt said this would be used for the realignment of the road, designed with center of double-lane roundabout but the approach is single-lane. Forty thousand of the estimated $190,000 is for acquisition of right of way property. The additional $150,000 is the estimated cost for aligning the road. Mr. Suhr expressed concern with entering the roundabout from the east or west during rush hour traffic. Mr. Lane replied it does not appear that it
