MEMO TO: Mayor and City Council <br />FROM: Brian Hoffman, Engineering Technician/Bldg. Inspector <br />DATE: February 26, 1987 <br />SUBJECT: PURCHASE OF A PLANIMETER <br />A planimeter is an instrument used to measure area of land from a <br />drawing cale. The Engineering Department is in need of a <br />planimeter to continue with the storm water analysis/design <br />project that we are presently engaged in. Although, a planimeter <br />is primarily needed for continuation of the storm water analysis <br />project, it is generally considered a standard piece of <br />engineering equipment and will be used on occasion for other <br />projects. Previously, we had been using a planimeter provided by <br />Steve Thatcher. The basic law cost mechanical planimeter is now <br />being replaced with the digital planimeter which are much more <br />expensive. However, a basic mechanical planimeter will meet all <br />of our foreseeable needs. The only model I have located locally <br />is manufactured by Lietz and is available through both Bronson <br />Equipment and Minnesota Blue Print. The following price quotes <br />were given: <br />Bronson Equipment $285.00 <br />Minnesota Blue Print $230.00 <br />I have discussed this issue with Clerk -Administrator Pauley who <br />has stated that the required monies could be withdrawn from the <br />Storm Water Management Fund considering the intended use for this <br />piece of equipment. <br />RECOMMENDATION: Staff recommends purchasing the Lietz <br />compensating polar planimeter from Minnesota Blue Print for <br />$230.00. <br />BH/bc <br />
