HomeMy WebLinkAboutRIGDEN FARM, PIONEER CHARTER SCHOOL - SITE PLAN ADVISORY REVIEW - 56-98U - REPORTS - TRAFFIC STUDYstudents at that school and the higher student population, it is concluded
that the number of waiting vehicles at the Pioneer Charter School would not
exceed this number (9). Therefore, the available curb frontage is
sufficient to accommodate the waiting vehicles with one dismissal time for
the entire school. Once dismissal occurs, the leaving vehicles will be
replaced by those parents that arrive and leave in a more timely manner.
It is concluded that the on -site curb frontage will likely handle the
expected student pick-up situation.
It has been demonstrated that the site plan for the drop-off and
pick -off area is probably adequate with one start/dismissal time. However,
below are listed a series of mitigation measures that should also be
applied to the analysis:
- At the Pioneer Charter School, at least one grade per day per week
has activities that are not at the main campus. More often than not,
students go directly to that site. Therefore, on a daily and peak
hour basis, the trip generation would be reduced by approximately 20
percent.
- The Pioneer Charter School intends to stagger the start/dismissal
times. The intention is to have two different start/dismissal times
for three grade blocks. If the start/dismissal time is staggered by
at least 30 minutes, the peak hour drop-off and pick-up
characteristics described earlier in this memorandum would be reduced
by 50 percent.
With the above mitigation measures, the drop-off and pick-up area operation
will be improved dramatically, such that there will not be any likelihood
that traffic will spill onto the public street system.
Kansas Drive, Limon Drive, and Minnesota Drive are all classified as
local streets. Local streets are typically 30 feet wide with the following
components: travel lane width-16 feet and parking lane width-7 feet (14
feet both sides). Rigden Farm was the first development to go through the
"City Plan" process. In the City approval, bike lanes were added to these
streets, even though bike lanes are not required on local streets. The
bike lanes are 6 feet wide (12 feet both sides). Therefore, the curb -to -
curb width of these streets is 42 feet. From the site plan, it can be seen
that parking is provided on all of these streets. Provision of this
parking will have a mitigating effect if some parents choose to wait/park
on the public street system adjacent to the site. The bike lanes on these
local streets will also provide for/encourage the use of alternate modes in
accessing this site.
This memorandum provides further clarification of my August 5, 2003
memorandum. It has been demonstrated that the trip generation will be less
than previously reported and the designated on -site drop-off and pick-up
area will adequately accommodate the expected traffic related to the
proposed Pioneer Charter School within Rigden Farm.

Given City staff comments, I believe that additional

information regarding transportation and traffic pertaining to the
Q
proposed Pioneer Charter School in Tract E at Rigden Farm is in
o
order. First of all, two corrections are that the student population

will be 360 students, not 380 as previously reported, and it will
zhave
grades 7 through 12. This will cause a reduction in the trip

generation.

In addition to the reduction in the calculated trip generation

using Trip Generation, 6th Edition, ITE caused by the reduction in the
number of students, the owner representative indicated that due to an
established program for carpooling and a high number of students who
walk and ride bikes, the daily trip generation was thought to be
high. There would be less faculty compared to that present at a
normal school_ The owner representative indicated that the daily
trip generation would be on the order of 700-800 rather than 1310
trip ends reported in my previous memorandum.
City staff indicated concern with regard to the ability of the
drop-off and pick-up area to handle the expected traffic. The
previously scaled 270 feet of drop-off/pick-up curb frontage has been

accurately measured at 300 feet. The previous analysis
indicated 130-140 drop-offs and pick-ups occurring before and after

school. With the reduction in the number of students, this would be

reduced to 125-135 (use 130). In the 20 minute peak period before

school, the average arrival would be 6.5 vehicles per minute (use 7).

At 40-50 feet of curb space (use 45 feet) per vehicle, the available
curb space can accommodate 6.7 vehicles per minute. The average

drop-off duration will be 30-40 seconds. It is concluded that the

Typically, the pick-up situation (school dismissal) is

different in that parents often arrive prior to the dismissal time
and wait for their students. The wait time is longer than the drop-
off time. Since parents are waiting for a longer period of time, the

vehicles will utilize 25-30 .feet of curb space. Therefore, 10
