Minutes of the Arden Hills Regular Council Meeting, 2-10-92 Page 6 . TILLER (Cont'd) circle suggested Tiller may not have received routine maintainence; asked if the City was negligent in would the Council consider amending the assessment policy maintaining the street, to a 60/40 split. Acting Mayor Malone explained the percentage is established in the assessment policy and would not be amended. He advised the road is approximately 38 years old and normal life span of a street is 20 years. Public Works Superintendent Winkel advised the road has been sealcoated over the years. Bob Emery, 1138 Tiller Lane, explained he has lived on this street since 1954 and he favored a decent roadway. He questioned what the cost per front foot is for =b and gutter installation. Emery commented the other end of the street may request bituminous surface. The Engineer stated it is approximately $5.00 per front foot. Ray York, 1151 Tiller Lane, stated his preference would be for a professional job of street reconstruction for future residents. He explained the street has been patched on several occasions and indicated it should be "done right". Wayne Vaughn, 1326 Tiller Lane, stated the residents may not have a problem with the reconstruction if they had not seen hOltl good Carlton Drive looks with only bitwninous overlay; agreed the upper portion of Tiller Lane may need . reconstruction, but not the the 10ltler portion of the street. Acting Mayor Malone asked for further COI1U1\el1ts from the floor and hearing no response, closed the public hearing at 8:30 p.m. Engineer Maurer atterrq:Jted to answer all citizen questions: - The installation of con=ete =b and gutters was discussed in conjunction with the adoption of the assessment manual. council determined the standard f= a typical city street should include =b and gutter, whether it is new street construction or reconstruction of an existing street. He advised the rationale for such installation was that =b and gutter is an important part of the drainage system and protects the edge of the roadway. Maurer advised the soils belOltl the existing roadway on Tiller Lane absorb moisture and holds it; lack of =b and gutter provides more opportunity for erosion of the roadway edge. - There are no "shortcuts" for street reconstruction. Deterioration of the street accelerates if the street is not property constructed. . - The soil engineer advised that 18 inches of corrective material should be sufficient to support existing traffic on Tiller Lane. A porous material will be placed over the existing soil. The material will allOltl pass water, renain dry and provide necessary support for the roadway. - 'lhere was no significant difference in the subsurface material along the length of Tiller Lane. The soils report does not address the existing roadway conditions; those were identified during the Pavement Management review program.
