and has an average daily traffic volume of 248 vehicles per day; and
WHEREAS, the Deschutes County Road Department conducted an engineering and traffic
investigation for Chaparrel Drive in accordance with ODOT criteria; the data, facts, and information
obtained in connection with said engineering and traffic investigation are given in the attached Exhibit

previous order with respect to the designated speed is greater than is reasonable under the conditions
found to exist upon Chaparrel Drive and has recommended a designated speed on Chaparrel Drive of
30 miles per hour (MPH); now, therefore

Notes:
1. Crash rate based on 2020-2022 Crash Data from 0DOT TDS Crash Reports and 2024 Traffic Count data
collected by Deschutes County.
2. Pedestrian and Bicycle activity based on volume data for study period from Strava Metro and oral
testimony from residents.
3. No Comparable Rate Available
4. Ten mile per hour range containing the largest number of sampled vehicles
S. Computed Speed is 85th-percentile speed minus Crash Rate Deviation (R-r)
6. Allowable speed computed according to Table 4 of Speed Zone Manual.
7. There are no access limitations for intersecting streets or residential driveways.
Factors Influencing Recommendation:
Section A: Cimarron Dr
• Several complaints have been received from residents of Cimarron City subdivision regarding
vehicle speeds.
• Area is residential only and residents use paved roadway cross-section for walking or biking
seasonally.
• One crash was observed at the intersection with McGrath Rd but was not speed -involved. Crash
data is not influential on the recommended speed posting.
• Driveway and access spacing is not consistent with statutory Residence District definition
according to ORS 801.430.
• Recommended speed is consistent with the mean observed speed.
Section B: Chapparel Dr
• Several complaints have been received from residents of Cimarron City subdivision regarding
vehicle speeds.
• Area is residential only and residents use paved roadway cross-section for walking or biking
seasonally.
• No crashes have occurred along the roadway segment and crash data is not influential on the
recommended speed posting.
• Driveway and access spacing is not consistent with statutory Residence District definition
according to ORS 801.430.
• Recommended speed is consistent with the mean observed speed.

BOARD OF
COMMISSIONERS
MEETING DATE: December 18, 2024
SUBJECT: Approval of Order No. 2024-050, establishing a designated speed of 30 mph on
Cimarron Drive, and Order No. 2024-051, establishing a designated speed of 30
mph on Chaparrel Drive
RECOMMENDED MOTION:
Move approval of Order Nos. 2024-050 and 2024-051.
BACKGROUND AND POLICY IMPLICATIONS:
Speed limits on all public roads in Oregon are set by state law in the Oregon Vehicle Code.
Implementation of a screed zone, which chanzes the speed limit on a liven segment of a
public road from the statutory speed limit, requires a speed zone order. Under the Oregon
Vehicle Code, the Oregon Department of Transportation (ODOT) is responsible for
conducting speed zone investigations to determine a recommended speed limit and for
issuing speed zone orders that set a new designated speed that differs from a previously
designated speed on county roads. However, under the current Oregon Vehicle Code,
ODOT can delegate speed zoning authority to a county for roads under the county's
authority with an average daily traffic of less than 400 vehicles per day. A county with this
delegated authority is required to conduct speed zone investigations in accordance with
ODOT standards.
Cimarron Drive and Chaparrel Drive both provide access to the Cimarron City subdivision
from McGrath Road. The current speed limit on Cimarron Drive is 45 miles per hour as set
by ODOT Speed Zone Order No. 2997; this order was adopted by ODOT in 1978, prior to
the current statute that provides for delegated authority on low volume roads. Road
Department records indicate that Road Department staff had made a request to ODOT for
a speed zone investigation in 1977 to reduce the 55 mph statutory speed limit on Cimarron
Drive in response to a vehicle crash involving a child pedestrian, and ODOT's investigation
yielded a recommended speed of 50 mph. Road Department staff objected to this
recommendation, indicating that a designated speed of 35 mph seemed prudent, and the
Oregon State Speed Control Board ruled for a designated speed of 45 mph with the above -
referenced order. Meanwhile, the current speed limit on Chaparrel Drive is the statutory
speed limit of 55 mph.
In recent years, the Road Department has received several requests from Cimarron City
residents for reduced speed limits on Cimarron Drive and Chaparrel Drive. In response,
Department staff conducted a speed zone investigation on both roads in October 2024; the
report from this investigation is attached to both proposed Order Nos. 2024-050 and 2024-
051. Based on this investigation, the Department is recommending a designated speed of
30 mph for both Cimarron Drive and Chaparrel Drive.
Both roads are functionally classified as local roads and are 0.94 mile in length each. The
roads lie within and provide access to MUM 0-zoned lands. The area adjacent to the roads
is residential in context, with residents using the paved roadway cross -sections for walking
and biking; however, driveway spacing along both roads is not consistent with the statutory
definition of a "Residence District", which would provide a statutory designated speed of 25
mph. The recommended speed of 30 mph is consistent with the observed 50t"-percentile
speeds (the speed at or below which 50% of vehicles were observed to be travelling during
the study) of 30.1 mph on Cimarron Drive and 33.6 mph on Chaparrel Drive.
Adoption of Order No. 2024- 050 will reduce the speed limit on Cimarron Drive from 45
mph to 30 mph, while adoption of Order No. 2024- 051 will reduce the speed limit on
Chaparrel Drive from 55 mph to 30 mph.
