MEMORANDUM TO: Steve Jankowski, P.E. Civil Engineer City of Ramsey FROM: Chris Chromy, P.E., P.T.O.E. Bryan Nemeth, P.E., P.T.O.E. DATE: March 7, 2007 SUBJECT: Rum River Meadows Roadway Connection City of Ramsey Project Description This document presents the traffic analysis for a proposed connection of the Rum River Meadows and Shade Tree Cottages to the intersection of Neon Street at 15ih Lane. The connection would be from the cul-de-sac of the Rum River Meadows (157th Avenue) going north to Neon Street. The residential properties that would primarily utilize this connection are located east ofCSAH 5 (Nowthen Boulevard), west ofTH 47, north of Alpine Drive and south of 157th Lane. The developments include 66 housing units consisting of 42 small-lot single-family homes in the Shade Tree Cottage development and 23 townhomes in the Rum River Meadows development. Traffic operations were analyzed at the proposed new connection of 157th Lane at Neon St. and TH 47 at 157th Lane. The current traffic at the two intersections was analyzed with and without the added traffic due to the connection. This study determines how well the existing roadways, roadway geometry, and traffic control handles the additional traffic with the proposed connection. Existing Conditions The intersection of 15ih Lane/Neon St. is residential and has no traffic control and no turn lanes. The speed limit for the residential area is 30 MPH. It is a three-legged intersection with north, east, and west legs. The intersection ofTH 47/15ih Lane is stop controlled with TH 47 having a free north and south thru movement. The speed limit on TH 47 is 55 MPH and on 157th Lane it is 30 MPH. This intersection is also a three-legged intersection with north, south, and west legs. There is a left -turn bypass lane on the northbound leg and a right turn lane on the southbound leg. H:\RAMS\T4222096\Report\ExtensionTechMemo030707.doc
