Therefore, no traffic calming measures are recommended for Dysprosium Street between CSAH 5 and CSAH 116. Iodine Street The internal roadway system of the proposed development will connect to Iodine Street, an existing roadway northwest of the development. Using Iodine Street, develOPment traffic traveling to/from the north will be able to access CSAH 5 via 146th Avenue. Since the majority of development trips travel to/from the south, it is estimated that the daily traffic volume on Iodine Street will only increase by approximately 70 trips per day with this connection to th~ proposed development. Providing a connection to CSAH 5 via Iodine Street is recommended in order to decrease traffic volumes and improve traffic operations at the CSAH 5/Site Access Roadway intersection. This connection will also provide street continuity and better emergency .vehicle access to the proposed development. If a connection is not constructed at Iodine Street, residents in the northwest comer of the proposed development will have a significantly longer travel distance when traveling to/from the north. Summary and Conclusions A residential development is proposed for the southwest quadrant of CSAH 5 and Dysprosium Street in the City of Ramsey. The proposed development includes 73 single-family homes, 152 townhome units, and 82 senior apartments. The purpose of this study is to examine the impacts this development would have on the adjacent roadway system. 'Based on the analysis, the following conclusions and recommendations are offered for your consideration: The intersections of TH 47/CSAH 5 and CSAH 5/Dysprosium Street currently operate at an acceptable LOS C or better.during the a.m. and p.m. peak hours, with existing geometrics and traffic control. With the construction of the proposed residential development, all key intersections are expected to operate at an acceptable LOS D or better during the a.m. and p.m. peak hours in the year 2004, with the intersection geometrics shown in Figure 5. In order to reduce conflict between tumin~through traffic and improve safety operations, a westbound left-turn lane and eastbound right-turn lane are recommended at the intersection of CSAH 5/Site Access Roadway. _ .~277-
