Subject: Paramount Southeast/ MPP15-0002/PP-15-002/RZ-15-001/CU-15-001
The Ada County Highway District has received multiple inquiries through the Tellus website this weekend
requesting that the Paramount Southeast applicant conduct a Traffic Impact Study. As you are aware,
ACHD did not require a TIS with this application. Information regarding the history, trips and traffic
counts is provided below.
Summary/History
This application is for a 28-lot preliminary plat consisting of 22 commercial lots, 1 multi-family lot,
and 5 common lots. The proposed rezone modifies the existing zoning boundaries between R-40
and C-G. The applicant is also seeking conditional use approval for 280 apartment units. ACHD
reviewed and approved this site in 2003 as part of the original Paramount preliminary plat. The
original application included 270 apartment units with a density of 18 units per acre. This
application has the same density on a reconfigured parcel. The apartments are estimated to
generate 1,862 vehicle trips per day; 174 vehicle trips per hour in the PM peak hour, based on the
Institute of Transportation Engineers Trip Generation Manual, 9 th edition. Trip generation
estimates for the commercial portion of the subdivision will vary depending on the nature of the
use.
The applicant, Brighton Corporation, entered into a Cooperative Development Agreement with
ACHD in 2007 to design and construct the signalization and widening of the Meridian/McMillan
intersection. The intersection was improved with 4-lanes and bike lanes on Meridian Road, and
3-lanes and bike lanes on McMillan Road.
ACHD policy sets guidelines for when to require traffic impact studies. The policy also states that
ACHD may waive the TIS requirement. ACHD did not require a TIS with this application because
development of this site was approved in 2003, and a TIS was required through that review and
approval process; and this application is consistent with the original concept plan that was
studied. In addition to the multiple intersections along McMillan Road that have been signalized,
many other roadways in the North Meridian area have been improved, and more are
programmed.
