I40 MINUTES <br />OF THE REGULAR MEETING OF THE <br />EDINA CITY COUNCIL HELD AT CITY HALL <br />APRIL 18, 1988 <br />Answering rollcall were Members Kelly, Richards, Smith, Turner and Mayor Courtney. <br />CAPTAIN LEONARD KLEVEN COMMENDED. <br />Kelven and stated that he began his employment with the City on January 1, 1969 <br />and moved through the ranks in the Police Department to the position of Captain. <br />Manager Rosland said that Captain Kleven was selected to attend the FBI National <br />Academy and graduated upon completion of the intensive course of training offered <br />at the Academy, having been on the deans's list. <br />Captain Kleven and commended him for his outstanding performance in the Police <br />Department. <br />in appreciation. <br />CONSENT AGENDA ITEMS ADOPTED. <br />Member Kelly to approve and adopt the consent agenda items as presented. <br />Manager Rosland introduced Captain Leonard <br />Manager Rosland congratulated I Captain Kleven was presented with a silver pen bearing the City logo <br />Members of the Council added their thanks and commendation. <br />Motion was made by Member Smith and seconded by <br />Rollcall : <br />Ayes: Kelly, Richards, Smith, Turner, Courtney <br />Motion carried. <br />PUBLIC HEARING CONDUCTED ON SOUND WALLS/SIGHT BARRIERS - HIGHWAY 100 FROM WEST <br />50TH STREET TO NORTH CITY LIMITS. Affidavits of Notice were presented by Clerk, <br />approved and ordered placed on file. Engineer Fran Hoffman stated that this will <br />be an informational hearing with presentations from the neighborhood Task Force, <br />the consulting engineers (Strgar-Roscoe-Fausch, Inc.) and staff on the effects of <br />sound walls/sight barriers. <br />involved in sound barriers as the implementing agency. <br />received a petition from neighbors to consider constructing barriers. The Council <br />responded by directing that a Task Force be appointed and a study be made on sound <br />walls/sight barriers with the assistance of consulting engineers. <br />Peter Fausch and Jim Kranig as the consultants. <br />Impact Study as follows: identification of the study area, neighborhood noise <br />issues, monitoring of noise levels, modeling of noise levels, mitigation <br />alternatives, preliminary construction cost estimates of alternatives, and funding <br />alternatives. Mr. Kranig explained that the standards used for the study were the <br />State L10 noise standards (noise level exceeded during 10 percent of the monitored <br />period) which for residential areas are a maximum of 65 decibels for daytime hours <br />between 7:OO a.m. and 1O:OO p.m. and 55 decibels for nighttime hours between 1O:OO <br />p.m. and 7:OO a.m. The Federal standard is a 24 hour standard at 70 decibels. <br />Noise levels were monitored with the results indicating relatively high daytime <br />L10 noise levels for homes which are within a few lots of bordering on Highway <br />100. <br />standard for many of the sites within the study area. <br />noise levels were 2 to 3 decibels lower than the daytime noise levels. <br />presented graphics to explain how noise levels were modeled and to illustrate the <br />noise level decibels for various areas within the study area. <br />alternatives were investigated including wall heights of 10 feet and 15 feet above <br />the pavement surface. He showed graphics of the peak daytime noise contours with <br />10 foot high and 15 foot high continuous walls. <br />study area in compliance with the State daytime standards for either wall meaning <br />that 60 to 70 houses would be brought into compliance. <br />contours with 10 foot high continuous walls indicated that approximately 160 to <br />170 houses would continue to exceed the State nighttime standards even with the 10 <br />He explained that currently the City has not been <br />During 198'7 the City <br />He introduced <br />Mr. Kranig summarized the Noise <br />Also, the nighttime noise levels were above or near the State L10 nighttime <br />In all cases, the nighttime <br />Mr. Kranig <br />Mitigation <br />The results showed all of the <br />Peak nighttime noise <br />i I <br />I <br />footwall. <br />to exceed the State nighttime standard. <br />costs for noise walls running along both sides of Highway 100 between West 50th <br />Street and the northern City Limits are estimated at $625,000 for a 10 foot wall <br />and $875,000 for a 15 foot wall. <br />which the costs of the walls could be assessed to the benefiting properties. <br />These range from a flat rate assessed to all of the properties defined as <br />receiving benefits to a complex assessment based on benefits per decibel <br />reduction. <br />examined for assessing costs resulting in an average cost per house ranging from <br />$3,200 to $18,900, depending on how benefit is defined. Cost per house would be <br />much higher for houses along Highway 100 if costs are assessed based on decibel <br />reductions. Mr. Kranig said that noise mitigation is not commonly done on <br />existing roadways unless the noise levels are decreased by 5 to 10 decibels and <br />that MNDOT requires a minimum of a 10 decibel reduction to ensure that the <br />benefits are perceived by nearby residents to be worth the cost. <br />identified a problem with truck impact noise at the Minnehaha Creek bridge. <br />reported that the Task Force was mixed on whether noise walls should be <br />constructed but was in general agreement that there should be property tax relief <br />for those properties which are significantly impacted by Highway 100 traffic noise <br />if no noise mitigation action is taken. Subsequent to the Noise Impact Study <br />report to the Council on March 21, 1988, and in response to the questions raised <br />as to highway noise throughout the City of Edina in general, Mr. Kranig said that <br />they spot monitored fifteen sites. The results were that essentially every site <br />was over standard with the exception of the area behind the noise walls on Highway <br />With the 15 foot wall approximately 100 to 110 houses would continue <br />Mr. Kranig said current construction <br />As to funding, there are a number of ways in <br />The study showed preliminary noise wall costs for the various methods I <br />The study also <br />He <br />.
