AGENDA ITEM 5 STAFF ORIGINATOR: David Ahrens, City Engineer /Public Works Director DATE: February 23, 1998 TOPIC: PUBLIC HEARING, 21st Avenue Street and Utility Improvements INTRODUCTION: On January 26, 1998, Council accepted a feasibility study and called for a public hearing for February 23, 1998, for the proposed improvements to 21st Avenue. The improvements include the installation of sanitary sewer, watermain, storm sewer and street. This public hearing is required per Minnesota State Statutes 429 and the Lino Lakes Charter. This project was initiated by petition from Mr. Gerald Rehbein, developer of the Clearwater Creek Business Center. The project will serve the General Business and Light Industrial zone of the City bounded by 35E, Main Street, 21M Avenue and Cedar Street. The northern portion of the area has received preliminary plat approval by Council. BACKGROUND: Proposed Improvements The sanitary sewer line was initially planned such that land north of Clearwater Creek would drain north to Main Street and east to Otter Lake Road through a cooperative project with the Metropolitan Council. This was based on the Metropolitan Council preliminary indication that they wanted to relieve the Centerville Forcemain capacity problems with a new sanitary sewer line along Main Street. Recently, staff has learned that the Metropolitan Council is not planning to pursue the Main Street sanitary sewer alignment and instead, install a new line parallel to the existing forcemain along Cedar Street. This change requires the City to serve the Clearwater Creek Business Center from the south and also construct a lift station near Clearwater Creek. Service stubs will be installed to serve adjoining properties. The proposed watermain is 16" diameter and will connect to the existing watermain in Cedar Street. The watermain will then extend north to serve the Clearwater Creek Business Center plat. Fire hydrants will be installed in accordance with City standards and service stubs will be included to serve adjoining properties. The proposed road width is 38 feet with concrete curb and gutter. The design strength is 10 tons which is standard for the adjacent land uses and expected traffic volumes and type. Storm water runoff from the street and adjoining properties will drain onto 21st Avenue and into catch basins and storm sewer pipe. Discharge from the storm sewer system will be to two proposed ponds located in the Clearwater Creek Business Center development.
