<br /> D~A P-T <br /> ,\( ~t-. <br /> ARDEN HILLS CITY COUNCIL - FEBRUARY 9. 1998 5 <br />. Mr. Brown explained curbing is an important aspect of a road reconstruction project to assist <br /> with drainage, to protect the edge of the asphalt from erosion, and to provide a better <br /> environment for maintenance. <br /> Vince Linders 1945 Glenpaul Avenue, inquired regarding the life expectancy for a <br /> reconstructed roadway. Mr. Brown stated it is 20 years according to MnDOT standards but that <br /> many roads, with minor maintenance, can last 30 to 35 years. He explained the layers of <br /> construction which are put into place under a reconstructed roadway. <br /> Mr. Linders reviewed how roadways are constructed in North Oaks which do not contain curb <br /> and gutter. Mr. Brown noted those roadways often contains ditches which provide for drainage <br /> away from the roadways. In Arden Hills, there are no ditch areas to address storm drainage. <br /> Mr. Linders asked if it is possible to construct Glenpaul Avenue without storm sewer. Mr. <br /> Brown stated it may be possible but he would not recommend it. <br /> Mr. Linders asked how much notice residents will receive and if they could be given four to five <br /> years notice. Mayor Probst stated since Glenpaul A venue was pulled from the project this year <br /> due to the soil boring information, he expects it will be added to the project for next year. <br /> Mr. Linders asked if the City can leave it as it is for five years to allow residents to start saving <br /> for this improvement. Mr. Brown explained that they will reevaluate all of the City's roadways, <br />. including Glenpaul Avenue, to determine which roadways need to be addressed first. Mr. <br /> Linders asserted there are other roadways in Arden Hills that are in worse shape than Glenpaul <br /> Avenue. <br /> Ms. Rem stated the issues involved with curb and gutter will not go away. She reported on. her <br /> conversation with the Watershed District about the benefit of curb and gutter. Ms. Rem noted <br /> most of the runoff in Arden Hills goes into ponds or wetlands. She stated the Watershed District <br /> had indicated to her they would prefer an urban design with a grass edge to filter runoff before it <br /> enters the wetlands. Ms. Rem asked if it is really cost effective to require curb and gutter which <br /> may not benefit drainage into wetlands. She asked whether it may be better to invest these funds <br /> into getting more roadways completed. <br /> Mayor Probst stated the City does believe it is cost effective. Also, Arden Hills does not have a <br /> storm drainage system so curb and gutter helps to direct drainage. Mayor Probst noted the City <br /> has been'installing grit chambers at the request of the. Watershed District. <br /> Mr. Brown clarified that Arden Hills does not have many urban section streets but, rather, streets <br /> with grass curbs where water runoff collects sediment more than if concrete curbs were present. <br /> He stated the solution is to install ponding. where appropriate, and grit chambers. <br /> The motion carried unanimously (5-0). <br />. <br />------- ------------- <br />
