Woe TO:
Monica Mika,
June 4, 2003 Director
COLORADO
FROM: Kim Ogle, Planner 1110 •
SUBJECT: USR 1426 - Vista Ridge Academy
Landscape, Fence and Screening Plan
The Department of Planning Services has reviewed Sheets 1 and 2 of 2 for the above
referenced case. Staff offers the following comments:
The Drainage Easement in the southeast corner of the site appears graphically to encumber
the Phase II Running Trail. It is suggested that the drainage easement be relocated so as to
not encumber this future improvement.
The proposed Landscape Plan drawings are accepted by this office. Staff has no further
comment.

RE: Vista Ridge Academy 10303.000
Dear Monica:
This letter is generated in response to Department of Planning Services' staff recommendations for a site
specific Development Plan and a Special Review Permit for a recreational facility. Attached are a
Fencing and Screening Plan, a Landscape Plan, and a site specific Traffic Report. All documents match
those that have been submitted to the Town of Erie in the form of a Site Improvement Plan for their
review and approval. The site that is shown in the plat documents will not contain any signage of any
kind, so a Signage Plan was not created for submittal at this time.
The landscape plan shows ballfields encircled by a crusher fines track, that will be private and fenced
along Ridgeview Drive. Additional fencing along Sheridan will be added in Phase II. Fencing is vinyl
coated chain-link and is intended to act as a deterrent to parking in the Ridgeview Drive ROW and as a
measure for safety for children using the fields. Adequate parking for use of these fields is provided at
the school site to the west, and is beyond the boundaries of this plat. Parking will not be permitted within
any public ROW. The use complies with all setback and offset requirements for the zone district.
Landscaping, sidewalks and roads that are shown within the ROW on Ridgeview Drive will be
constructed and designed by Vista Ridge Metropolitan District, and location is for general intent only.
Landscaping and sidewalks that are shown along Sheridan will also be constructed and designed by the
Vista Ridge Metropolitan District and location is also for general intent only.
Sincerely,
SLATERPAULL ARCHITECTS,INC.

Re: Vista Ridge Academy

(LSC #030260)
Dear Mr. Korcuska:
'df
We are pleased to submit this site specific Traffic Impact Analysis of the proposed Vista Ridge
Academy to be located north of Ridgeview Drive and west of Sheridan Boulevard in Erie,
Colorado. The Vista Ridge Traffic Impact Analysis(TIA) dated December 19, 2000 evaluates the
overall impacts of the Vista Ridge development. The proposed site was assumed to be office/
commercial in the December, 2000 TIA and is now proposed for a private school serving grades
K-12 with a capacity of 250 students. Access to the site is proposed from Ridgeview Drive with
two full movement access intersections. This analysis evaluates traffic impacts at the site's
access points. Recommendations are also made for drop-off/pick-up traffic control. The
remainder of this letter summarizes our findings.
Site Location and Proposed Land Uses
The location of the proposed Vista Ridge Academy is shown in Figure 1. It is located north of
Ridgeview Drive and west of Sheridan Boulevard. The proposed site will contain a private
school with a capacity of 250 students.
Surrounding Roadway Network and Background Traffic Conditions
As shown in Figure 1, the Vista Ridge Academy will access Ridgeview Drive which connects
to the surrounding road network at Sheridan Boulevard and Mn e
w Drive. sed
lane geometry and traffic controls are illustrated in Figure 2 and adesscription of the
surrounding roadway network is as follows:
• Sheridan Boulevard is proposed as a four-lane arterial connecting 1-25 on the north (
with 120"'Avenue on the south. The Ridgeview Drive intersection will be signalized `6°.
when MUTCD traffic signal warrants are met. !;
•
Mr. Russ Korcuska Page 2
March 7, 2003
• Mountain View Drive is proposed as a collector roadway with a signalized inter-
section with SH 7. It will loop north and west to Vista Ridge Parkway.
• Ridgeview Drive is proposed as a two-lane collector roadway connecting Sheridan
Boulevard on the east with Mountain View Drive on the west.
2020 Background peak-hour traffic volumes on Ridgeview Drive are illustrated in Figure 3 and
are based on buildout of the Vista Ridge development as contained in our December, 2000 TIA.
Trip Generation
Vista Ridge Academy is planned to ultimately accommodate 250 students. The amount of
traffic that will be generated by the private K-10 school with potential future 11"' and 12th grades was determined using trip generation rates published by the Institute of Transportation
Engineers in its report Trip Generation, 6"' edition, 1997, and is shown in Table 1. As shown,
on a typical weekday the school can be expected to generate about 820 vehicle-trips per day,
with 410 vehicles entering and 410 vehicles exiting the site in a 24-hour period. During the
morning peak-hour, approximately 138 vehicles will enter and 93 vehicles will exit the site.
During the afternoon peak-hour, about 73 vehicles will enter and 88 vehicles will exit. During
the evening peak-hour, there will be about 20 entering and 30 exiting vehicles.
Estimated Traffic Distribution and Assignment
The directional distribution of project-generated traffic on the roadways providing access to
and from the Vista Ridge Academy is one of the most important elements in determining its
related traffic impacts. Major factors which influence the traffic distribution include:
• The location of the site related to population and activity areas;
• The roadway system providing access to and from the site;
• The specific access plan designed to serve the site.
Figure 4 illustrates the percent distribution of the project-generated traffic. It is expected that
about 60 percent of the traffic would be oriented to the east on Ridgeview Drive and 40 percent
oriented to the west.
The assignment of project-generated peak-hour traffic is also shown in Figure 4 and was
calculated by applying the trip distribution percentages in Figure 4 to the trip generation
estimates given above.
2020 Total Traffic
Year 2020 projected peak-hour traffic volumes are illustrated in Figure 5 and reflect the
combination of 2000 background traffic from Figure 3 and project-generated traffic from
Figure 4.
Mr. Russ Korcuska Page 3 March 7, 2003
Capacity Analysis
Based upon the peak-hour traffic volumes shown in Figure 5, "Unsignalized Intersection
Capacity" analyses have been performed, using procedures set forth in the 2000 Highway
Capacity Manual. The concept of Level of Service (LOS) is used as a basis for computing
combinations of roadway operating conditions which accommodate various levels of traffic
activity. By definition, six different Levels of Service are used (A, B, C, D, E, and F) with "A"
being virtually a free-flow traffic condition and "F"being a total congested condition. Analyses
have been performed for both the morning and evening peak-hour periods for 2020 back-
ground plus site-generated traffic. The results of these capacity analyses are enclosed and are
summarized in Table 2.
The results of the capacity analyses indicate that all movements on the Ridgeview Drive/site
access intersections will operate at acceptable Levels of Service (LOS "D" or better on all
movements) with the addition of project-generated traffic.
Drop-Off/Pick-Up Recommendations
In the design of any school site plan, it is important to provide adequate on-site areas for drop-
off/pick-up of students. In order to properly size such an area for Vista Ridge Academy,
queuing analyses were performed as summarized in Tables 3 and 4 for the drop-off and pick-
up periods, respectively.
For the drop-off period, it was assumed that about 70 percent of the morning peak-hour
arriving vehicles (or 100 vehicles) would use the drop-off area with the remaining vehicles
using the parking lot. It was assumed that these 100 vehicles would randomly arrive over a
20-minute period or an arrival rate of five vehicles per minute. It was further assumed that
two vehicles could unload simultaneously and that each vehicle could stop and unload in 15
seconds. Using these parameters and standard queuing formulae it was calculated as shown
in Table 3 that the 95th percentile queue would be six vehicles.
In a similar manner, pick-up queues were estimated as shown in Table 4. Due to more car-
pooling and students staying for after-school activities, fewer vehicles are expected to arrive
during the peak pick-up period, but they will be concentrated in a shorter period. It was
assumed that 60 vehicles would use the pick-up area and would randomly arrive over a 15-
minute period or an arrival rate of four vehicles per minute. The loading time would be some-
what longer at 20 seconds per vehicle,with two vehicles picking-up simultaneously. As shown
in Table 4, the 95' percentile queue would be seven vehicles. Based on these calculations,
it is recommended that 200 feet be provided for the drop-off/pick-up area which would be
adequate for eight to ten vehicles.
In addition, two traffic monitors should be stationed on the site as shown in Figure 6. One
monitor should be stationed at the head of the queue to direct pick-up activities. The other
should be stationed at the cross-walk crossing the drive loop to safely cross students and
parents to and from the parking lot. Finally the loop drive should signed and striped for one-
way operation as shown in Figure 6.
Mr. Russ Korcuska Page 4 March 7, 2003
Conclusions
Based on the foregoing analysis,the following conclusions can be made regarding the proposed
Vista Ridge Academy:
1. The Vista Ridge Academy will contain a private K-10 school with potential future 11th
and 12th grades with an ultimate capacity of 250 students. It will be located north
of Ridgeview Drive and west of Sheridan Boulevard.
2. The distribution of trips to and from the site will be such that 60 percent of project-
generated traffic would be oriented east on Ridgeview Drive and 40 percent will be
oriented west.
3. All movements on the Ridgeview Drive/site access intersections will operate at a
acceptable Levels of Service (LOS "D" or better on all movements) with the addition
of site-generated traffic. Due to the low volume of traffic expected at the site access
turn lanes will not be required.
4. The drop-off/pick-up area should be at least 200 feet in length and be appropriately
signed.
5. Traffic monitors should be stationed at the head of the drop-off/pick-up area and at
the crosswalk.
6. The traffic impacts of the Vista Ridge Academy are relatively minor and can be
adequately served by the surrounding road network.
We trust that the above information will further the planning for the Vista Ridge Academy.
Please let me know if we can be of additional assistance.
