signal warrant will not be met until the westbound volume exceeds 150
vehicles per hour. This will not likely occur until more development occurs
within-Rigden Farm. It is likely that the development of the commercial
parcel within Rigden Farm would cause the peak hour and, potentially, other
signal warrants to be met at the Timberline/Custer intersection.
It is concluded that the trip generation for the Seven Oaks Academy
will be higher than the land uses contemplated for the parcel in the
original Rigden Farm plan. However, since other nearby parcels have been
proposed and built at a density that is less than that analyzed in the
cited TIS, the impact will be mitigated. It is expected that a signal will
not be warranted at the Timberline/Custer intersection until there is
considerably more development within Rigden Farm.

Alternative modes analysis was provided for the Rigden Farm
N
development, therefore, additional alternative mode analysis is not

required.
In the cited study, this parcel within Phase A of Rigden Farm
contained 41 apartment dwelling units. From Table 2 of the cited
study, this parcel was expected to generate 272 daily trip ends, 21
morning peak hour trip ends, and 25 afternoon peak hour trip ends.
The Seven Oaks Academy at Rigden Farm is proposed to have 150
regular day care students and 48 infant care students. Using Trip
Generation, 6ih Edition, ITE as the reference document, this parcel is
expected to generate 895 daily trip ends, 161 morning peak hour trip
ends, and 170 afternoon peak hour trip ends. The Seven Oaks Academy
will generate more daily and peak hour trip ends compared to the
(L
apartment land use shown in the cited TIS. However, it should be
cc
noted that development proposals for other parcels, adjacent to and

nearby the Seven Oaks Academy parcel, have generally had lower trip
compared to that shown in the cited TIS. While the daily

and peak hour trip generation will not be a "wash," the increase will

not be the multiple times increase indicated in the straight

comparison.

City staff requested a peak hour count at the Timberline/Custer

intersection to determine whether signal warrants are close to being
a
met. While peak hour. signal warrants alone are seldom used to

install a traffic signal at any location, they are a gauge to

determine when other signal warrants are close to being met. In

addition to this, they are the easiest signal warrant to predict.
