The typical residential traffic impact study covers the four main intersections within a one-half mile radius of the development to determine their adequacy to handle the new increase in daily traffic volume from the new residents.
For this development, three of the four intersections were more than adequate to handle the increase in traffic that was calculated. The fourth intersection, located at Ashlan and Fowler proved to be inadequate, specifically at the left turn lane for southbound Fowler.
Once the future bottleneck was identified, Yamabe & Horn pulled GIS maps for the intersection to determine which frontage was the best to absorb to create the extra turn lane.
There is a gas station to the east and Starbucks to the west, making the choice obvious to absorb the frontage on the west since the gas station has underground tanks and essentially zero frontage space to absorb.
Having worked with the City of Fresno and Clovis for many years, Yamabe & Horn was able to deliver the TIS and recommendations on behalf of Lennar to get the improvements approved with little managerial involvement from
