Item No. 6E Type of Business: CA WK: Work Session; PH: Public Hearing; CA: Consent Agenda; CB: Council Business City of Mounds View Staff Report To: Honorable Mayor and City Council From: Greg Lee, Director of Public Works Item Title/Subject: Resolution No. 5716 Approving the Purchase of Replacement Gates for the Public Works Facility Meeting Date: February 25, 2002 Background: For the past several years there has been an operational problem with the gate at the Public Works Facility. The problem is due to the grade of the parking lot and the general design of the gate. When the gate was designed and installed, a trench was created on the east side of the gate to allow the gate to open and close. This was necessary due to the grades within the parking lot and the extraordinary long length of the gate. During the winter months, the trench becomes filled with snow and ice making it difficult to open. This causes undo wear on the motors and controls. The motor and controls are currently inoperable and in need of repair / replacement. The cost to replace the motors and controls would be approximately $1,500. However, this would not address the design issue of the gate which is the real cause of the problem. The combination of not having a clear passage for the length of the gate along with having an oversized gate would continue to apply resistance on the new control/motor and would prematurely require their replacement. A design solution was therefore sought. Altering the elevation of the par king lot was investigated. However, due to the elevation of the parking lot and street height and the existence of the fuel station, the parking lot could not be altered to compensate for the gate length. The solution was to redesign the gate so that it consists of two smaller separate sections, located on each side of the driveway entrance. This new design will address the problems that have occurred with the existing gate. The replaced gates will reduce the overall load and resistance thus create an ease of operation that will reduce the strain on the clutches and motors. The end result will be that the gates open and close smoother and faster and the motor and clutches will have an increased longevity.
