Item No: 7G Meeting Date: October 24, 2016 Type of Business: Council Business Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Brian L. Erickson, Public Works Director/City Engineer Item Title/Subject: Resolution 8651, Approve Design and Authorize Seeking Quotes for Stormwater Improvement at 2255 Lambert Avenue Background: In December 2015 staff applied for, and ultimately received, a grant from the Rice Creek Watershed District (RCWD) as part of their Urban Stormwater Remediation Cost-Share Program. The agreement was approved by the City Council at their June 27, 2016 meeting. Since that time the staff has prepared a design for completing this work and is ready to seek quotes to perform this work. Discussion: The project is located at 2255 Lambert Avenue and would replace an open and poorly vegetated ditch with reinforced concrete pipe. This ditch, which connects between two city storm sewer lines, is being eroded and depositing sediment in the city’s storm sewer system with each rain event. This sediment requires removal from the system in the future in order to insure proper functionality. By installing concrete pipe the erosion is eliminated and results in reduced maintenance into the future. Additionally, this should improve the water quality of downstream waters. Staff is working with the property owner to insure that proper easements are established along this work. Primarily the easement will be along the lot line to the west of the existing home. Some additional easement may be required over and above the typical 5-foot side lot line drainage and utility easement. It should be noted that the existing ditch does not have any easements except for the extreme northeast corner of the property. Once completed, this project will also assist the property owner by providing a more usable lot. The funding for this work would come from the Storm Water Fund (745-4415-7050) which included $50,000.00 in the budget for this work. There is also an additional $25,000 in the budget for other storm water projects. At this point, there are no additional projects planned for 2016 and staff would propose using $1,752.50 of that line item to fund this work, if needed. In addition, the grant funding from RCWD is $19,292.00. This results in a total funding amount of $71,044.50. This funding would cover engineering, construction and construction contingency. Should none of the contingency be required no additional funding from the other storm water project would be used. The table shows the total project estimate and funding for this work.
