Mr. Jim March <br /> June 17, 1997 <br /> Page 3 <br /> Option 5 - Full Reconstruct with Concrete Curb <br /> Option 5 includes all aspects discussed in Option 4, but a concrete curb would replace the <br /> bituminous curb. This concrete curb would be consistent with what is now being used within <br /> the City, but would add to the construction cost. This option does not include any cost for <br /> storm sewer, but could be added as needed. <br /> The estimated cost for this option is: <br /> Heritage Street: $28,425.00 <br /> Lamotte Drive: $49.795.00 <br /> Total Construction Cost $78,220.00 <br /> Other Considerations <br /> Before making a final decision on a pavement option for Heritage Street and Lamotte Drive, <br /> we would recommend having soil borings done on these streets to determine the existing <br /> geotechnical properties of the materials in the road cross section. A geotechnical exploration <br /> may indicate the need for a sand subbase, ge textile fabric, and drain tile to offer enough <br /> support for the pavement in some or all areas. This would allow for a more accurate decision <br /> on what pavement option will be most cost effective. <br /> We hope that this information is useful to the Centerville City Council for making a decision <br /> about the pavement concerns on Heritage Street and Lamotte Drive. We will be in <br /> attendance at the June 18th Council meeting to answer any questions the Council may have <br /> about the information contained in this letter. <br /> Sincerely <br /> Howard R.
