-1 0 4— UPDATE ON IP 08 -06 ANDRIE STREET IMPROVEMENTS IN NORTH FORK SUBDIVISION By: Steven Jankowski, City Engineer CASE # q Background: This case is being prepared subsequent to the approval of the Committee's recommendations which were ratified by the City Council on April 8, 2008 relating to Improvement Project 08 -06. This project originally proposed the standard bituminous overlay of Andrie Street and three cul de sacs to the north on 164 Lane, but is now being considered to be expanded in scope. The purpose of this case is to provide a project cost estimate and description for the expanded scope of the work and also outline the next steps for public involvement. The improvements associated with an expanded scope of the project for Andrie Street would include the following: • Reclamation of the existing bituminous and class 5 for reuse as a new base. • Placement of 2" of bituminous base and 1 %" of bituminous wear course on the road. • Installation of B style (high backed) concrete curb and gutter. • The installation of a 10 foot bituminous trail along the east side of Andrie Street and the north side of 164 Lane. • Replacement of all the existing storm basins and the addition of approximately 1200 feet of storm sewer to improve drainage: • Restoration of driveways, irrigation systems, and lawns with seeding. • Retaining wall is anticipated in selected areas. It is proposed that the new roadway would be approximately the same width as the existing street, 32 feet from flowline of curb to flowline of curb as compared to 31 feet on the existing street. Two eleven foot drive lanes are proposed with an eight foot parking lane on the east and north sides and a two foot curb reaction extension on the west and south sides. Parking would also need to be restricted on this side of the street. The three cul de sacs, Halas, Fol titian, and Driscoll Circles, would receive a 1 Y2" bituminous overlay of the existing pavement at the same time as Andrie Street is reconstructed. Attached is a preliminary cost estimate which projects the total project cost, including 25% for overhead to be $1,317,886 with an MSA cost of $1,194,842 assuming the assessment to the fronting property owners would be the equivalent of the one and one half inch bituminous overlay proposed for the current IP 08 -06. A neighborhood meeting will be scheduled for Wednesday April 23'' between 6:30 and 8:00 pm to present the project description outlined above.
