Howard R. Green Company <br />Project No. 814130J <br /> <br /> Feasibility Study <br />Bituminous Street Improvements <br />On 221st Avenue <br /> Elk River, Minnesota <br /> <br />INTRODUCTION <br /> <br />This feasibility study was authorized by City Council Resolution 01-21, adopted at their April 9, 2001 <br />meeting at the request of the Developers of the Ridges of Rice Lake project. This feasibility study <br />was initiated by the City Council based on the development of two parcels that abut the roadway. <br /> <br />This study was conducted to determine the feasibility of paving 221 st Avenue within the City. The <br />street considered for improvement is shown on Exhibit 1. <br /> <br />SCOPE <br /> <br />The purpose of this study is to analyze the feasibility of paving 221st Avenue from CSAH 1 (Elk Lake <br />Road) to the City Railroad Trail. This study will discuss the existing conditions, proposed <br />improvements, and estimated project costs. The total project cost consists of construction costs <br />plus overhead costs, which include City administration, engineering, fiscal and legal expenses. <br />Minnesota Statute 429 will be followed to assess benefiting property. <br /> <br />EXISTING CONDITIONS <br /> <br />Developers of the Ridges of Rice Lake project have expressed a desire to have 221st Avenue <br />bituminous surfaced. The existing roadway is currently surfaced with gravel only. 221 st Avenue is <br />in good condition as a gravel road, but requires frequent grading and has periodic dust concerns. <br />This street serves all of the homes within the project vicinity, and paving will offer many benefits, <br />including a cleaner neighborhood appearance, less traffic noise, less wear and tear on vehicles and <br />increased traffic safety. The traveled street currently ranges from 26 feet to 27 feet wide, with a total <br />length of approximately 6,659 feet, or 1.26 miles. This street has a rural cross section with roadside <br />ditches. <br /> <br />Traffic counts were taken on this road in 1999. The average daily traffic count was 150 vehicles. <br />The traffic volume is predominantly vehicles from the abutting residential properties and truck traffic <br />from the gravel operations and landfill. This street has had regular maintenance in order to maintain <br />the granular surface. The street currently has approximately 6-8 inches of gravel material, which is <br />in good shape and will make an excellent roadway base for the bituminous pavement. <br /> <br />PROPOSEDIMPROVEMENTS <br /> <br />The project includes 221st Avenue from CSAH 1 (Elk Lake Road) to the City Railroad Trail and is <br />shown on Exhibit 1. This street collectively serves approximately seven homes. The proposed <br />development, The Ridges of Rice Lake, contains an additional 70 units. <br /> <br />The proposed improvements to the road will create a street width of 24 feet of bituminous pavement <br />and 2 feet of gravel shoulders on each side. The existing gravel will be used as a sub-base, and an <br />additional 2 inches of gravel will be placed and graded to obtain a standard crown on the surface. <br />Subsequently, 3% inches of bituminous surfacing would be placed in two lifts consisting of a 2-inch <br />base course and a 1%-inch wearing course. No soil borings have been obtained at this time, and <br />the pavement section will be dependent on the findings of the soil borings. <br /> <br />O:LPROJ~814130JXFeasibility Study. doc <br /> <br /> <br />
