Steve Mefhven Cwmimity Develapmern Depamneirt City of Paris 150 -1~ Street SE Paris, TX 75460 Dear Mr. Methven: Per your request, our engincering fum has investigated the differences between two proposed locations of a cellular tower east of the downtown area of Paris. One site is located at the SE corner ofthe inteisec,~tion of Hwys 271 & 82 (Sibe I). The other sight is locabed approximately 1400 feet slightly west of noith of the fitst tower (Site 2). As I undecstand it, both pmposed towers are approximately 180 feet in height We have only investigated the technical differences between the two toweis. Other factors including aesthetics, proximity ro residences and rea1 estates costs were not considered. The iasues we studied wee redio coverage and potential penetation problems into the Watmart store nearby the toweis. It was reported that a ridge (temain) lies approximately'/z mile noith of Site 1. Our study showed a ridge of approximately 25' at.6 mile north of Site 1. Ota propagation analysis showed no effact of the ridge on coverege from either site. This is undentandable since both toweis were analyzed at 180 fcet above ground The horiwn distance for a tower of 180' is approximately 20 miles. ff the ridge was a problem with the coveiage in the area, Site 2 would see less effect of the ridge because it is appioximabely 25 miles closer to the ridge, thus, less shadowing will nsutt. Our radio ProPagation study (coverage) showed insignificant diffetences between the stes. In fact, Site 2 showed a slighfly better coverage mainly because the elevation at the site was sliBhtlY hiP~ (approxknately 8'). Conceming the rddio propagation into the Walmart building, it is my wnderstanding that the birilding is closer to Site 2 which should give better signal levels within the building. However, because of the clase pmximity of the subjed sites, it is my opinion that either site will give about the same sigoal shength within the strucdue. If thece is a problem with sigmi strength witliln the facility> ttere aze ways to effecfively enhance the sigrials inside the building. 1425 Greenway Drive, Suite 350, Irving, Texas 75038, 972/580•1911.
