The City Transportation staff has been working with the High School as it
concerns Impala Drive. The problems related to the High School are not so much
traffic flow or level of service related as they are to the issue of behavior,
i.e. the speeding.issue. There have been discussions of closing a portion of
Impala that would result in the High School gaining access only from Laporte Ave.
At this time, resolution of this issue has not been finalized.
It is important to recognize that the from a Traffic Engineering standpoint, the
local street will operate at acceptable levels of service with the addition of
the Impala Village development.

IMPALA VILLAGE - TRAFFIC ANALYSIS
Per your request, please consider this memorandum as the written documentation
of the traffic analysis for the Impala Village P.U.D. The traffic impacts
associated with the Housing Authorities proposed Impala Village P.U.D. have been
evaluated and determined to be acceptable for local streets in Fort Collins.
Based on ITE Trip Generation Rates, an apartment. complex has an average trip
generation rate of 6.103 trips per dwelling unit. At the proposal of 56 dwelling
units, an average of 342 trips per day could be assumed to be generated from the
apartment complex. All streets in the immediate vicinity of the project are
operating at below capacity and the impact of 342 trips on the local street
system in this area is acceptable. ITE morning peak hour rates also assume an
average rate of 0.568 trips per dwelling unit. For the purpose of this analysis,
I assumed the trip distribution for the a.m. peak hour trips went south and used
the Impala/Mulberry intersection. Using the ITE peak hour rates, an additional
32 vehicles would be entering the intersection during the morning peak. The
number of vehicles associated with this development do not create a sufficient
impact to warrant traffic operational improvements.
Traffic accidents at the intersection of Impala and Mulberry were also examined
for the years 1991 and 1992 (see attached sheet). During this period, there were
three accidents (two rear ends and one broadside). With signalization, the
broadside accident may have been prevented however, it is likely that rear end
accidents would have increased.
Mulberry at Impala in 1992 carried approximately 3200 vehicles per day and Impala
carries approximately a 1000 vehicles during the school year. Based on the low
volumes, it is unlikely that a traffic signal would be warranted at this
location. Additionally, Impala and Ponderosa are offset at the intersection of
Mulberry which would make signalization expensive and difficult to be effective.
Based on observation, there appears to be sufficient gaps in the traffic flow on
Mulberry accommodate southbound left turning vehicles on Impala.
