At most locations on Applicant's Sheet ZC-4, the boundary between the R-1 designation <br />and the POS designation is from 4 to 6 pixels wide. At 17.5' per pixel, this means that the <br />boundary ranges from 70 to 105 feet wide. In addition, bleed-over may have resulted from <br />the very bright yellow color of the R-1 zoning designation into the more subdued greenish <br />POS designation. <br />The surveyor correctly states that the accuracy of any map is dependent on the least <br />accurate component, which, in this case, is the Metro Plan Diagram. However, as LHVC <br />Sheet 9/2/15-04 shows, a much higher accuracy can be achieved at higher scan resolutions. <br />The scan performed by the City of the Metro Plan Diagram is at a resolution of 1,200 dpi, <br />or 3 times more precise than the scan utilized by the applicant. In other words, pixels on <br />the City's scan are only 6 feet on a side. Moreover, the transition zone from R-1 to POR <br />ranges from about 16 feet to 24 feet wide. This means that the actual boundary can be <br />established within tolerances that are less than 25% of those which arise from use of the <br />applicant's map. <br />Given the large errors arising from use of the applicant's poor scan of the Metro Plan <br />Diagram, this scan is essentially unsuitable for establishing the correct location of the <br />boundary between R-1 and POR designation. Regardless of the registration issue (see <br />Allegation 2, below), it is recommended to disregard any and all of the applicant's maps <br />which are based on the scan for Sheet ZC-4. <br />Applicant's Allegation 2: It is Impossible to Use More than One Referent at a Time <br />As part of their submission at the hearing, the applicant provided 24x36" hard copies of 4 <br />versions of their Sheet ZC-4. These each purported to use one of four referents. Sheet ZC- <br />4A utilizes the Centerline for 30' Avenue, Sheet ZC-413 utilizes the "Green Finger", Sheet <br />ZC-4C utilizes the Centerline of Spring Boulevard, and Sheet ZC-4D utilizes Bloomberg <br />Park. We disagree with all four proposed registrations of the applicant's property on the <br />Metro Plan Diagram. Some registrations are better than others, but all can be significantly <br />improved. <br />Annotated versions of the four maps presented by the applicant are attached. These maps <br />were prepared on scans of the applicant's hard copy maps made by City Staff The original <br />surveyors map was overlaid on the scans (purplish pink annotation) and adjusted (rotated <br />and scaled) to match the applicant's referents on the scanned map. Once registration was <br />achieved with the applicant's proposed property boundary location, the pink layer <br />containing the surveyor's map was copied and pasted onto the map in light green. This <br />layer was then moved (without rotation) until the green overlay matched all the referents <br />as well as possible. All the referents include the centerline for 30r' Avenue, the centerline <br />for Spring Boulevard, the "Green Finger", and Bloomberg Park. Whereas it is true that <br />there is no "perfect" registration, especially on the applicant's poor-quality scan, the <br />registration with all referents can be performed significantly better than the applicant has <br />achieved in their quest to minimize POS zoning on their property. Moreover, the green <br />overlays are all very similar to the registration obtained last year on LHVC Sheet 9/2/15- <br />04. <br />Laurel Hi llValleyCitizens@gmaiLcom . 2585Moon Mountain Drive .
