Dear Mr. Diamente,

At your request, I have reviewed the proposed multi-family development with respect to the number of
vehicles that will be generated and the surrounding roadway system. The proposed development will be
located on the existing RCI office building site. The office building is approximately 230,000 square feet with
access to the site primarily from Michigan Road. The proposed development will consist of 360 multi-family
units and approximately 8,000 square feet of retail, which will most likely be a sit-down restaurant.
A&F Engineering conducted a field review of the site as well as a trip generation calculation to determine
what impact the future multi-family development would have on the surrounding street systems.
The following table is a summary of the trip generation for the proposed development as well as a comparison
of trip generations for potential uses that could occupy the site. These trip generation data are taken from the
ITE Trip Generation Manual 11th Edition. The “Total” trips represent the total trips that can be expected at the
access drives during the AM and PM peak hours. “Pass-By” trips represent trips that are already in the
existing traffic stream along the adjacent public roadway system that enter a site, utilize the site, and then
return to the existing traffic stream. A “Non-Pass-By” trip is a net new trip added to the roadway system.
Additionally, the table shows the sum of the entering and exiting trips for each trip type for the AM and PM peak
hours.

Based on the field review and the trip generation calculations, the following conclusions and
recommendations are provided:
• Based on the trip generation study, it can be seen that when fully occupied, the existing site would
generate significantly more traffic during the AM and PM peak hour as compared to the proposed
multifamily development.
• Based on a field review and the number of vehicles that will be generated by the multi-family
development, the existing access points will adequately function for the site.
• Michigan Road is a 4-lane divided roadway which provides significant capacity and, therefore, the
proposed use will not negatively affect the surrounding street system.
