SITE RANKING DOCUMENTATION 
Site/Segment Parameters Description of Parameter Candidate #1 (SAMPLE) TEDDY/RANCHO

Location Is the entry for a specific point along a road segment, or is it 

representative of a whole road segment? If the entry is for a point, provide a moniker and the latitude and longitude. If for a road segment, identify where the segment boundaries occur (such as an intersection, mile marker, or political boundary).

This location is representative of a whole road segment. No egress/igress from Sahara Ave. to Spring Mountain Rd. Except for the Charleston Blvd controlled exchanges, the entire I15/Las Vegas Freeway volume of vehicular traffic from the I15/US 95/ US 93 interchange travels past the Teddy/Rancho site.

Road segment name Given road name and common name (if applicable). I15 Southbound/Las Vegas FreewayRoad type Type of road (controlled access highway, limited access 

freeway, arterial, etc.).

Controlled access highway

Road segment end points Location of the road segment end points, including any given 

names, common names, and the latitude and longitude of each individual end point.

not flat, identify whether the configuration is a vertical or sloped boundary. Include the height and degree of slope if applicable.

Terrain Nature of the terrain immediately around the road; also, any 

largerǦscale terrain features of note.

Meteorology Predominant winds for a point, and whether the point is 

relatively upwind or downwind. For a whole segment, the orientation of the segment to the predominant winds.

Predominate winds will be light and variable with radiational inversions in the 

evening and morning hours. Predominate winter time weather will be high 

pressure with subsidence.

Population exposure Assessment of population exposure and/or likeness to other 

road segments throughout the CBSA.

Athletic facility, child care, mobile home park, and senior apartments located 

west of site within one kilometer. Commercial businesses and large casino/hotel also within one kilometer. Not a dense resident population
