MOUNDS VIEW City of Mounds View Staff Report Item No: 7F Meeting Date: September 23, 2013 Type of Business: Council Businless Administrator Review: To: Honorable Mayor and City Council From: Nick DeBar, Public Works Director Item Title/Subject: Resolution 8157, Approving Cooperative and Maintenance Agreements with Ramsey County for Traffic Control Signals at Intersection of CSAH 10 and Silver Lake Road Background: County State Aid Highway 10 (CSAR 10), or also known as County Road 10, is a Ramsey County controlled roadway that handles over 20,000 vehicles each day. In 2009, the City identified the need to revise the signal to allow for protected/permissive left turn phasing for vehicles on Silver Lake Road/Red Oak Drive. The City applied for and received Highway Safety Improvement Program (HSIP) funding due to a high number of left turn crashes at the intersection. Currently, left turn phasing is permissive only. Between January 2005 and December 2007, fifteen (15) crashes occurred at the intersection, including four (4) personal injury crashes. Six (6) of the crashes involved vehicles making left turns from the Silver Lake Road/Red Oak Drive legs of the intersection. The HSIP grant of $266,220 was awarded based upon a high benefit to cost (B/C) ratio of 7.17, and is eligible to cover up to 90% of construction costs. Public Works staff recommended that Ramsey County assume the lead agency role on the project since three of the four intersection legs are under Ramsey County jurisdiction. The Council agreed and Ramsey County was amenable. Ramsey County performed final design and prepared bidding documents for the improvements. A public bid occurred and the low bid of $387,383.51 was awarded to Forest Lake Contracting, Inc. of Forest Lake, Minnesota. A preconstruction meeting occurred on August 28, 2013 and construction is scheduled to begin soon. Discussion: Mounds View has jurisdiction over one of the four legs of the intersection (Red Oak Drive). This ratio (1:4 or 25%) is used as a mechanism for assigning costs to multiple agencies with roadway jurisdictions for intersection improvements. There are standing policies that Ramsey County has for cost participation on certain improvements that they do not participate. One of these items is the Emergency Vehicle Preemption (EVP) Systems, which local governments are responsible for 100% of the costs. A detailed construction cost and participation distribution tables are included with the Cooperative Agreement (attached). In summary, Mounds View is responsible for $72,640 of the $387,383.51 construction cost. The HSIP grant amount of $266,220 is not enough to cover 90% of the total construction cost and is being applied on a prorated basis to the various intersectional legs. Mounds View's grant portion is $49,920.09 which reduces the local cost share to $22,719.91. However, the pole and base painting ($2,093.06), and design and construction engineering reimbursement to Ramsey County (12% of total construction cost for design engineering ($8,967.97) plus 12% for construction engineering ($8,967.97) increases Mounds View's cost share to $42,748.91. This amount will fluctuate due to the unit price basis of the construction contract and will be reconciled at the end of the project. Attached to this report are two agreements between Ramsey County and the City of Mounds View. The first is a cooperative agreement that addresses the design, bidding, and construction phases of the project. The second is a maintenance agreement that addresses the operation and long-term maintenance of the traffic control signals. Both agreements are standard agreements used by Ramsey County and similar to previously approved agreements, most recently at Silver Lake Road and County Road H.
