The engineer provided the original CAD file of the exhibit. The engineer also <br />explained how the exhibit was generated. <br />"The boundary on my map was generated from County Map data, and the <br />topography is from aerial mapping sources. We did not order a boundary <br />survey or a topographic survey, thus no legal description of the boundary <br />was prepared." <br />In other words, none of the data on that map is surveyed. See marked up Figure 2, attached, <br />containing applicant comments. Also see attached full size submittal (Figure 4) that is a map <br />created from the original AutoCAD file obtained directly from the engineer. The applicant's <br />surveyed data was overlaid onto the engineer's not surveyed GIS data. The inaccuracy of <br />the GIS/LiDAR data is obvious. <br />The engineer also provided a copy of the aerial photo, with topography and tax lot lines, and <br />a copy of the tax lot map both of which were used in generating the annexation application <br />exhibit. <br />Importantly, the annexation exhibit which staff utilized was NOT generated with surveyed <br />data. At that time there was no survey of the subject property, and, even as today, only tax <br />lot maps were utilized to locate those lines on the map. In summary, staff's second <br />measured drawing is faulty and cannot be used. <br />3. Figure 3 from City Submittal, dated September 28, 2016. <br />Staff then made a third measurement. Here, staff obtained GIS map data of the west end of <br />the subject property and measured the distance from the property's western boundary to the <br />same line as the aforementioned traced city limit lines. Not surprisingly, staff measured the <br />distance as 850 feet. In response, the applicant reviewed this third figure from staff and <br />notes the following. <br />• In the lower right-hand corner of staff's Figure 3 is the note "For General Reference <br />Only." <br />• Across the top of this figure are the words "Graphical Representation" and "Local <br />Government GIS Data." <br />See applicant's marked-up Figure 3, attached. <br />The applicant asks, if the figure is for "general reference only", and was generated with "local <br />government GIS data", how valid is the information, and the measurement, on this particular <br />drawing? The applicant sought to verify the validity of this GIS data and discovered that the <br />accuracy of GIS data cannot be verified. Every "local government" which supplies GIS data <br />includes a standard disclaimer. Four local government GIS sources were consulted and four <br />local governments provided their standard disclaimer language. A copy of each of these is <br />enclosed with this letter (Figures 6, 7, 8 and 9), but each is summarized below. <br />Figure 6.
