- e . the height of the storage tank is necessary due to the distillation process ofthe nitrogen. The applicant has stated that the storage tank would meet Guidant's current need plus leave room for approximately 12% extra. This extra room should sustain Guidant's nitrogen need for the near future. If additional tanks were necessary in the future staff would recommend keeping the height at 50 feet or less instead of adding a taller tank. It appears that sightlines to the nitrogen storage tank should be partially or completely obscured in most locations, Some ofthe locations are obscured behind the penthouses of Buildings A, B, and C. Other locations are not obscured by the penthouses but do have wooded areas which should provide some screening, mostly seasonal. In addition, the nitrogen storage tank would be more than 700 feet from any residence. Due to the distance and screening, most properties would not have a clear view ofthe proposed nitrogen storage tank. However, the top 8-20 feet may be partially visible from some locations, The buildings along the west side of the Guidant Campus are: Building A - 43 feet main roof{l023 Above Sea Level), 57 feet penthouse (1037 ASL); Building B - 28feet main roof (1 008 ASL), 42feet penthouse (1022 ASL); Building C - 28feet main roof{1008 ASL), 42 feet penthouse (1022 ASL). 3. Noise - Meets requirement Guidant Corporation had a noise test performed to determine the noise level produced by the nitrogen generator in comparison to the noise at three points to the North (location A), West (location B), and South (location C) of the Guidant Campus. The noise test concluded that noise levels produced by the proposed system should not exceed 46 dba. In comparison the noise levels at locations A, B, and C would not be less than 56 dba (tested at 4:30 AM) when the area should be at its quietest levels, Based on the conclusions of this test staff is comfortable that the nitrogen generator should not have any noise impact on the surrounding residential area, 4. Parking - Meets requirement Currently the area where the nitrogen generator, vaporizers, and storage tank are proposed is occupied by an impervious surface which houses motorcycle parking and approximately 5 cars wcre also parked there (not designated on Master Plan as parking stalls). It appears that there should continue to be adequate parking through the two surface lots directly north and south of this site and also the newly completed parking structure located to the southwest of this site, 5. Traffic, Access, and Circulation - Meets requirement The impact on traffic, access, and circulation to the site may be noticed both internally to the campus and to the broader community. Internally, the proposed equipment would be out of the traffic flow lanes and should not have a negative impact on the internal traffic flow, In addition, the reduction of trucks delivering liquid nitrogen also eliminates much of the \\EarthIPlanning\Planning Cases.\2004\04-18 Guidant PUD Amendment Nitrogen Generator (PENDING)\lO-20-04 PC Report Guidant PUD Amendment for Nitrogen Generator.doc Page 4 of6
