FROM:
A&F Engineering Co., LLC
RE: Jackson Grant / Village Center
A&F Engineering prepared a traffic impact analysis in 2011 on behalf of Silvara Real Estate
Company LLC, for a proposed mixed-use development located along Spring Mill Road, north of
116th Street called “Silvara”. A portion of this site has been constructed. However, the proposed
“Village Center” portion of the site is currently 100% undeveloped. Per the previous land plan,
the land uses in the Village Center included approximately 18,000 square feet of general office
space, 52,000 square feet of general retail shops, and 60 townhomes. Per a new Village Center
plan, this site will include 55 townhomes, 19 single-family dwelling units and 20,000 square feet
of general retail shops. The following tables summarize the AM and PM peak hour trip estimates
for the previous and new Village Center plans.

The generated trips from the new Village Center plan were assigned and distributed to each of
the proposed access drives and to Hamlet Drive. The resulting total AM and PM peak hour
generated traffic volumes from the Village Center are shown on the attached figure.
CONCLUSIONS
• Based on the number of trips that will be generated by the proposed Village Center, it can
be seen by comparing Table 1 to Table 2 that the new uses will generate approximately
the same number of trips during the AM peak hour. However, during the PM peak hour,
the proposed Village Center will generate significantly less. Approximately 388 vehicles
fewer during PM peak hour.
• A review of the attached figure shows the vehicles that are anticipated to enter and exit
the site at the proposed access points along with the intersection of 116th Street and
Springmill Road. Based on the number of vehicles shown at each of the access points, it
can be seen that this proposed development will have minimal impact to surrounding
streets and the intersection of 116th Street and Springmill Road. Based on the number of
vehicles that will be using the intersection, no modifications are required.
RECOMMENDATIONS
• Springmill Road access point
Based on the number of vehicles entering and exiting this access point, this driveway
should be designed as a right in, right out, left in only. By providing the left in off of
3
Springmill Road, it will reduce the number of vehicles on Hamlet Drive by 65 in AM
peak hour and 56 in PM peak hour.
• 116th Street access point
This driveway should be designed as a full movement access point that would allow for
right in, right out, left in, left out and through movements. The driveway should be
designed with two Outbound lanes – one exclusive left turn lane and one shared through
and right turn lane. Currently 116th Street is wide enough to provide for a left turn lane
into the driveway. However, pavement markings should be modified for a left turn lane.
