January 7, 1998 Dennis Welsch Page Two (educed its capacity. Because the roadway was projected to be near its capacity in 2010 based on the original configuration, the new configuration coupled with an increase in traffic trom the proposed site would likely place Hamline Avenue over its capacity. I have had discussions with Dan Soler, Ramsey County Traffic Engineer, regarding Everest's proposal. It is Mr. Soler's opinion that an increase in traffic such as that proposed would likely (esult in a need for modifications to the intersection of Ham line Avenue and Commerce Street. The upgrade would likely be a change to a 5-1ane configuration with dedicated turn lanes, Because of the expansion of the roadway, it is also Jikely that additional right-of-way would be required to accommodate the new intersection. The traffic signal would likely also need to be modified. It is possible that an improvement of this type would be (equired in conjunction with construction of the applicant's proposal. A traffic study was completed by BRW in 1997 to detennine the impacts of potential uses for the State Farm site north of Commerce Street. It was BRW's feeling that a change in use resulting in increased traffic from the State Fann site would create the need to improve the Hamline Avenue- Highway 36 inte(change to accommodate the additional traffic. It is possible that the increase in traffic associated with the current proposal would have the same affect on the interchange. MnDOT has expressed concern regarding the current Highway 36 Interchange. It is likely they would be interested in a reconfiguration of the interchange as part ofa redevelopment. Utilities With regards to sanitary sewer capacity, I have obtained SAC unit information from Don Munson, the City's Permits Coordinator. The infonnation is summarized as follows: TYPE OF USE SAC UNITS Medium Densitv Residential 32 General Office 21 MedicalIDental Facility 25 There is currently an 8-inch sanitary sewer within the Hamline Avenue right-of-way adjacent to the site. The existing line has the capacity to carry the flows which would be generated by a medium-density residential development. Both a general office and a medical/dental facility of the size proposed would generate less flow than the medium density residential use. Therefore it is not anticipated that there would be a sewer capacity problem if the proposed development were constructed.
