Subject Existing CellTelephone Towers Observation - Proposed Residential Plat,
18809 116th Avenue S.W., Renton, WA Parcel Number: 322305-9075
Dear Sir:
On May 15, 2016 this office visited the above site to review general site conditions and
to observe two celltelephone easemented fence enclosed facilities. One located in the
northwest corner contained two major steel pole towers with minor operation/
mechanical buildings. The other, located along the north line of the site at approximate
mid-point, contained only a single operation/mechanical building. Based on available
easement records, the facilities were installed in 1997 or soon after.
As observed during the visit, the northwest enclosure celltowers were observed to be in
good original condition. The interior of the enclosure was well kept with minimal
vegetation. There was no indication that the towers or their foundations had deteriorated
in any way. Our experience is that the design and installation or these towers is
substantial and provided with well adapted safety factors, and under heavy permit
review.
Based on the observations at the time, and during subsequent visits as recently as mid-
January 2018, the towers are in good original condition and retain their original
design/installation structural capacities.
Concerning either administrative or structural concerns for the locating of residential
uses adjacent to the enclosed sites, none is known. We know of no reason for
restricting or requiring setbacks from the enclosed facilities. The same type and scale
of facilities are located routinely in public accessed commercial and retail locations.
Emissions from these facilities should not be confused with those from high-tension
alternating current power transmission lines.
Attached are photographs taken during the site visit.
Thank you for your assistance.
