CASE # PUBLIC HEARING ON IMPROVEMENT PROJECT #05-24 STREET GRADING AND PAVING OF SAINT FRANCIS BOULEVARD FRONTAGE ROAD SOUTH OF 160TM LANE By: Steven J Jankowski, City Engineer Background: The City received a petition for street grading and pavement improvements to the Saint Francis Boulevard frontage road located south of 160th Lane from all three of the residents fronting along this street. A feasibility study has been prepared by City staff for this proposed improvement which was reviewed by the Public Works Committee on IV[arch 15, 2005. City Council ordered a public hearing for tonight's meeting on March 22, 2005. Attached to this case is a copy of the feasibility study which outlines the above improvements. Notice has been sent to all benefited property owners as required by City Code and Minnesota Statues Chapter 429 along with a copy of the feasibility study. The existing street consists of a graded native sand base roadway with rural roadside ditches on both sides. The roadway is approximate 21 feet wide for a length 700 feet south of 160th Lane. This segment is terminated with an egg shaped cul de sac which is approximately 80 feet long and 60 feet wide. This existing roadway is not centered within thc 45 foot right of way that is dedicated for this service road on the plat of the Hall Anderson subdivision. Instead it appears that the east edge of the roadway is located on the east right of way. This project proposes to grade and pave the roadway to a width of 32 feet with 24 feet dedicated for roadway purposes and the western eight feet reserved for trail use. The pavement section shall consist of 4 inches of class 5; two inches of bituminous base course and 1.5 inches of bituminous wear course. The additional 11 feet of width necessary for this proposal would be accommodated by extending the pavement westward from the existing traveled dirt street alignment. This would result in the ,ax/sting residences being located between 45 to 55 feet from the edge of the paved roadway. Irt order to confine the widened roadway to the 45 foot right of way reserved for the City, and to minimize impacts to existing landscaping it has been proposed to install a bitulninous berm curb along the western edge of the pavement. The southern terminus of thc roadway shall be provided with a 70 foot diameter cul de sac. This is approximately l0 feet wider than the existing dirt cul de sac. It will be necessary to install a storm cul vert along TH 47 to maintain the drainage from the highway. -123-
