Item No. 10G Meeting Date: July 12, 2004 Type of Business: CB WK: Work Session; PH: Public Hearing; CA: Consent Agenda; CB: Council Business City Administrator Review _______ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Greg Lee, Director of Public Works Item Title/Subject: Trunk Highway 10 Noise Wall / Berm Project Resolution No. 6302 Authorizing the Preparation of Final Plans and Specifications, and Submittal of a letter to Mn/DOT Requesting the Installation of a Noise Abatement Wall in the Arden Park Area Background: On June 7, 2004, Ulteig Engineers presented a draft report which had draft designs and cost estimates for Phase One of the Trunk Highway 10 Noise Wall / Berm Project. Phase One starts in Arden Park where the existing wall terminates and runs easterly past the LaPort Neighborhood to Jackson Drive. Phase one is then broken down into three segments: Segment "A", the area adjacent to Arden Park, Segment "B", the wetland area east of Arden Park and west of the LaPort Neighborhood, and finally Segment "C", the LaPort Neighborhood. For segment "A", the report called for extending the existing wall approximately 432 feet to the east and then tying it into a berm - at an estimated cost of $213,758.05. For segment "B", the report called for a berm - at an estimated cost of $89,177.00. For segment "C", the report called for a 15-foot high wall - at an estimated cost of $347,690.20. These were “construction costs” only and did not include engineering, administration, staff, and landscaping costs. At the June 7th Work Session, Staff stated that if these construction costs were adjusted to reflect estimated total costs, that segment A would be equal to or greater than $300,000 - the amount promised to the City by Mn/DOT. Given this, Staff recommended that the City contact Mn/DOT and demand that they install the wall through the Arden Park area (Segment A) as they were originally required to do.
