OTTER LAKE ROAD NORTH EXTENSION AND UTILITY IMPROVEMENTS CITY OF LINO LAKES, MINNESOTA EXECUTIVE SUMMARY The purpose of this Report is to analyze existing conditions and determine the feasibility of improving Otter Lake Road north of Main Street (CSAH 14) as a new collector road along with sanitary sewer, watermain and storm drainage improvements necessary to serve a new business area development and in accordance with the preliminary alignment. The report will also include a proposed completion of the signal system at the Main Street intersection. This area is guided for commercial development and is proposed as an "A" Minor Arterial in both the City and County transportation plans. CSAH 14 (Main Street) will have a significantly larger volume of traffic in comparison to Otter Lake Road. This is requiring the need to provide vehicle stacking at the intersection to allow the through traffic to continue as long as possible. The proposed lane configuration is a five -lane road. The ultimate lane configuration will be a seven -lane road just north of Main Street and then reducing in lanes as the road continues north to its connection with Elmcrest Avenue. The ultimate lane configuration will require the need for double left turn lanes to also provide for minimal stoppage of the through traffic. The Improvements are anticipated to be implemented in three phases and the first phase costs will be estimated in this report. Phase No.1 will be the first 440 feet north of Main Street. Phase No. 2 will be from 440 feet north of Main Street to 1215 feet north of Main Street. Phase No. 3 will be from 1215 feet north of Main Street to a proposed connection point at Elmcrest Avenue, approximately one mile north of Main Street. The total estimated project cost of Phase No.1 is $895,000. The estimated costs include a 5% contingency and indirect costs (administrative, legal, engineering, acquisitions, wetland mitigation, and bonding). The project is proposed to be funded initially with bonds taken out by the City and reimbursed through assessments and $22,850 from the City's Utility Funds. The watermain extension has an estimated project cost of $78,000. Watermain improvements will be paid by each of the two benefitting property owners. The estimated cost for watermain improvements is $27,575 per property. The remaining costs of $22,850 are for trunk system improvements the City would benefit from having, and therefore would be covered by the City's Page 1 14817.004
