Feasibility Study <br />Little Canada Road/McMenemy Road Parking Lot Improvements <br />III. Necessity and Cost Effectiveness <br />The City of Little Canada has a Pavement Management Program in place. The purpose of this <br />program is to maintain and improve the street and parking lot systems in the City. Surfaces with a <br />pavement condition index rating (PCI) of 0 to 60 are candidates for reconstruction as they show <br />signs of advanced pavement deterioration. Surfaces with a PCI rating of 61 to 80 are candidates for <br />surface rehabilitation such as recycling or milling and overlaying. Those with a PCI rating in the <br />range of 81 to 90 are candidates for preventive maintenance such as crack sealing and seal coating. <br />Surfaces with a rating between 91 to 100 would require no maintenance. Based on the amount of <br />surface cracking, pot holes, and the thinness of the bituminous surface (some areas less than 1" <br />thick with only a clay soil base) of this parking lot it has an estimated PCI rating of 30 out of 100, <br />thus justifying reconstruction. This project is necessary to provide our residents who use this <br />parking lot, a safe and adequate area to park their vehicles. <br />IV. Existing Conditions <br />In general, this parking lot is showing a great deal of surface distress including a large amount of <br />alligator cracking, bumps, potholes. Prior to placement of a large bituminous skin patch in the fall <br />of 2000, the base material was exposed and investigated. It was determined that where ever the <br />bituminous surface is failing, there was little if any granular base material present. Further, <br />approximately 30% of the lot surface has been patched. <br />V. Proposed Improvement <br />Four different reconstruction alternatives have been developed for this parking lot. The goal is to <br />provide a parking area that is safe, easy to access, has good traffic flow patterns and provides the <br />most parking spaces possible. Both two -way and one -way traffic pattern alternatives were <br />developed. In addition, we looked at 9' and 10' wide parking stalls as well as 30' and 24' wide <br />curb cuts. Figures 2 shows the Parking lot prior to the Respite Home being built. Figures 3, 4, 5, <br />and 6, show the alternatives developed. All of the alternatives developed include the following: <br />• Concrete curb on the parking lot side of Little Canada Road and McMenemy Road only. <br />We propose to leave the existing bituminous curb on these roads in an effort to reduce <br />costs. <br />• Three banner poles are to be removed as part of the Little Canada Road project. We <br />propose to relocate them to this parking lot with one at each entrance and one in the 20' <br />by 20' area in the northwest corner of the parking lot. <br />• The 20'by 20' area in the northwest comer of the parking lot would be surfaced with <br />concrete pavers similar to those we are putting in as part of the Little Canada Road <br />project. <br />• We are trying to find a low growing shrub or plant material that is not susceptible to salt <br />that can be placed in the 5' area between the parking lot curb and road curbs. If this can <br />not be done, we are proposing to pave this area with a bituminous material. <br />Page 3 <br />\ \CLCSRVOI \ HOME \GregS \Parking Lot\Peasibility Study.doc <br />
