HomeMy WebLinkAboutPINNACLE TOWNHOMES - PDP - 34-00A - CORRESPONDENCE - CITIZEN COMMUNICATION (5)S. We disagree with the finding of the TIS that a left turn lane is not required on Prospect Rd. at the
entrance to the proposed development. In Appendix C of the TIS there is a chart labeled "Volume
Warrants for Left Turn Lanes at Unsignalized Intersections." This chart uses a prediction of 10 turns
per hour into the proposed development during the peak afternoon traffic period. Using the peak traffic
count of 1041 vehicles per hour shown in Figure 3 of the citizen's data, the chart would indicate that a
left turn lane is warranted by the proposed development.

5. The TIS makes inaccurate statements about the required level of service. In Section 4.5.3.A.3.b and
Table 4-3 of the Standards, the threshold for acceptable service in a low density mixed use residential
area at a signalized intersection is defined as "D." A threshold of D refers to a 35 to 55 second average
delay at the signalized intersection (Standards Attachment H).
The TIS states on page 3, "Per City standards, overall level of service `E' is defined as acceptable for
arterial street intersections." This statement is incorrect. The TIS states on page 21, "As shown above,
acceptable operations are expected under both the short- and long-term conditions." This statement is
incorrect because it also refers to an inaccurate reading of the Standards.
We believe that the TIS is invalid because it bases its conclusions on incorrectly applied Standards.
6. We dispute the finding in the TIS of no negative impacts on the level of service at the signalized
intersection at Prospect and Lemay. In Section 4.5.2.A.2 of the Standards it says,
A project is defined as significantly impacting a study intersection when ... the
following criteria are satisfied:... When the background traffic conditions
(without project traffic) causes an intersection to fail the minimum acceptable
level of service standards; and when the project traffic causes more than a 2
percent increase in the intersection delay.
In Figure 3, the largest measured count of peak hour traffic was 1041 vehicles per hour. This represents
a 20% increase when compared to the TIS. We assert that the level of service at the intersection of
Prospect and Lemay would be below acceptable standards if the citizen's data were used in the analysis.
Furthermore, on page 9 of the TIS it states, "As shown above, Pinnacle Townhomes is expected to
generate... 30 afternoon peak hour trips... per day." The projected impact of 30 afternoon peak hour
trips is larger than 2 percent of the measured afternoon peak hour traffic. Thus we believe that the
project meets the definition of "significantly impacting a study intersection" as defined in the Standards.
7. The omission of accident data from the TIS is significant. The citizens have obtained accident
statistics for E. Prospect Rd. These data are shown in Figure 5. The intersections at Remington and
Lemay are rated as "Severe" for accidents by the City of Fort Collins. The intersection at Stover
accounts for about 25% of the total number of accidents in this corridor. The Stover intersection is
especially important because of the proximity to drop-off points for nearby schools. We believe that
accidents and safety are important issues that were ignored in the TIS.

Citizens Concerns - Issues With Traffic Study
Some elements of the Pinnacle Townhomes TIS are in conflict with the Larimer County Urban Area
Streets Standards:
1. The TIS used non -representative data. The data were collected during the summer when 4
educational institutions located on this stretch of Prospect were not in session. Furthermore, a
substantial number of CSU students access the campus using Prospect Street. The University was not in
session when the data were collected (August 10, 2000).
Section 4.3.2.A of the Larimer County Urban Area Streets Standards says, "The intent of completing an
analysis of the existing (current) study horizon is to establish a baseline of traffic conditions."
Section 4.4. LA states, "The Local Entity may require the use of seasonal adjustment factors depending
on when data was collected..."
We contend that the conclusions of the TIS are in doubt because the data were collected during a season
in which the traffic was consistently less than average. This non -representative sample of traffic data
defeats the purpose of the study outlined in section 4.3.2.A. We request that the City of Fort Collins
apply a seasonal adjustment factor per section 4.4. LA and then request a revision of the TIS.
2. The TIS is missing some required "key elements." Section 4.3.4.B of the Standards states that a TIS,
"...shall include the following evaluations:"
1...
2...
13. Safety and accident analysis
14...
15. Neighborhood and public input issues
The TIS does not contain an analysis of accident and safety issues. The author of the TIS did not solicit
input from citizens of the neighborhood, nor from the public at large. We believe that the TIS is invalid
because it is missing these required key elements.
3. The TIS does not report the data in the required format. Section 4.4. LA of the Standards says, "Each
peak hour count shall be conducted over a two hour period and shall include fifteen (15) minute count
data to clearly identify the peak hours.
The TIS contains appendices in which a variety of data are reported. However, nowhere in these
appendices are the 15 minute counts reported in the way specified by the Standards. Because the data
are not reported per the Standards, it is not possible to "clearly identify the peak hours" used in the
analysis. We believe that this error in data reporting invalidates the survey.
4. The citizens conducted their own traffic counts using the methods outlined in the Standards. The data
from these counts are presented in Figures 1 and 2 below. The data were collected on Tuesday February
5, 2002. Data from the peak morning and evening hours, in each direction of traffic, are displayed in
Figures 3 and 4. In Figures 3 and 4, the data collected by citizens is compared to the peak hour data
reported in the TIS. The comparison shows that in every case the current traffic volume is higher than
reported in the TIS; in one case the traffic is more than 50% higher than reported in the TIS.
