1116 <br /> Arden Hills <br /> Summary and Analysis of <br /> Emergency Services Calls in 2011 and 2012 <br /> Prepared by Dr. Linda Tomaselli, GISRDC <br /> June 10, 2013 <br /> This report summarizes the patterns for Emergency Services calls for the years 2011 and <br /> 2012 in the City of Arden Hills. The city provided call data from The Ramsey County <br /> Sheriff and the Lake Johanna Fire Department. The calls were matched to parcels and <br /> roadways. The specific methodology used is summarized in Appendix A. <br /> Using the call time records in each file,the amount of time spent on each call was <br /> calculated. This report summarizes the amounts and patterns of calls with respect to <br /> locations in the city, land use,major generators of the calls, and call type. <br /> I. Overview of Emergency Services Calls <br /> In 2011 and 2012 there were 8,894 emergency services calls. For some reason, 202 calls <br /> could not be matched to a parcel,valid address range or street name in Arden Hills. As a <br /> result,there was a net total of 8,692 calls in the city for that period. <br /> • A. Calls by Land Use <br /> A summary of the calls by land use category is provided in Table 1. <br /> Residential land uses were responsible for the greatest percentage (38.6%) of time spent <br /> on the 8,567 calls matched to the city. Single family residential had the greatest amount <br /> (21.2%), while the mobile home park was responsible for 11.9%. <br /> Tax exempt land use had 23.4%of the call time,with church or charitable uses having <br /> 6.6%, private schools with 6%and public schools with 5%. <br /> Streets and highways had 17.5%, most of which(7.62%)was for county state aid <br /> highways (CSAH). Federal and state highways had 4.7% and 2.7%,respectively. <br /> Commercial uses were responsible for 16.5%of the call time, most of which came from <br /> shopping (5.3%) and office (3.0%). <br /> Industrial was responsible for 2.3%of the time,with vacant and other uses having less <br /> than 1.7%. <br /> The pattern of emergency services calls is shown on Map 1.
