BR W INC Planning Transportation Engineering Urban Design Thresher Square 700 Third Street So Minneapolis, MN 55415 612/3704)700 Fax 612/370-13:^ Denver Milwaukee Minneapolis Orlando Phoenix Portland San Diego Seattle Memorandum DATE: TO: FROM: October 11, 1995 Keith Dahl Howard Preston, PE. Vice President of Traffic Engineering Jeff Holstein, PE, Senior Traffic Engineer RE:SCOTCH PINE ADDITION; Scotch Pine Lane Vacation We have investigated the traffic-related issues associated with the vacation of Scotch Pine Lane as proposed on the SCOTCH PINE ADDITION Preliminary PlaL It is our understanding that the proposed action would result in an additional residential access drive to Hennepin County State Aid Highway 51 (CSAH 51) approximately 250 feet east of existing Scotch Pine Lane and that existing Scotch Pine Lane would be vacated as a public street and maintained in it’s current location as a common residential driveway. The proposed new access drive would serve one home and the common access drive would serve two houses. The following paragraphs describe the traffic-related issues that were investigated and the conclusions of our analysis. Appropriate Access Snacinti Alone C.SAH 51 The appropriate access spacing along CSAH 51 is dependent upon the design function or functional cla.ssification of CSAH 51. Roadways are typically divided into functional clas.ses for purpo.ses of applying design criteria, establishing jurisdictional authority and determining available sources of funding. The two characteristics that determine a roadway ’s functional classification are acce.ss and mobiliiv. These two functions conflict with each other as the roadway network attempts to serve its two basic purpo.ses. Typically, the greater the access, the less the mobility that is possible and as the degree of access is limited, the mobility of the highway segment is increa.sed.
