AGENDA REQUEST & STAFF REPORT
For Board Business Meeting of June 25, 2014
DATE: June 17,2014
FROM: Peter Russell CDD Phone (541) 388-6718
TITLE OF AGENDA ITEM:
Consideration of Second Reading by Title Only and Adoption of Ordinance 2014-001 Amending
Deschutes County Code 17.16.115 to Move Traffic Study Requirements and Update Cross-reference
and Consideration of Second Reading by Title Only and Adoption of Ordinance 2014-017 Adding and
Amending Deschutes County Code Chapters 18.116 and 18.124 to Include Traffic Study Requirements
and Update Cross-references.
PUBLIC HEARING ON THIS DATE? NO
BACKGROUND AND POLICY IMPLICATIONS:
The Board held a first reading of Ordinances 2014-001 and 2014-017 on June 4, 2014. There have
been no changes to the ordinances since the first reading. The current traffic study requirement has
appeared since 2006 in Deschutes County Code (DCC) 17.16.115, which deals with master plans and
subdivsions. Traffic studies are required when a use will generate 50 new weekday trips. A more
logical location would be under DCC 18.116, Supplemental Provisions, as the County often receives
land use applications that are neither a subdivision nor a master plan, but will generate more than 50
new weekday trips.
Additionally, the County code now has different performance standards for existing roads and new
roads. The proposed ordinances will set the County's performance standard for all roads regardless of
age as Level of Service (LOS) D. Finally, the proposed DCC 18.116.310 will allow the County the
discretion to waive the traffic study requirement for low-intensity uses that meet the 50-trip threshold,
but are located in isolated areas and on County roads with adequate capacity.
FISCAL IMPLICATIONS:
None.
RECOMMENDATION & ACTION REQUESTED:
Motion 1: Second reading by title only of Ordinance 2014-001.
Motion 2: Adoption of Ordinance 2014-001
Motion 3: Seeton reading by title only of Ordinance 2014-017
Motion 4: Adoption of Ordinance 2014-017

WHEREAS, Deschutes County Planning Division staff requested a text amendment to Deschutes
County Code ("DCC") 17.16.115, 18.116.310, and 18.124.080, to move traffic study requirements from 17.16
(Approval of Subdivision Tentative Plans and Master Development Plans to 18.116 (Supplementary Provisions),
establishing 18.116.310 (Traffic Study Requirements) and updating 18.124 (Site Plan Review) reference to
traffic studies; the reason is many land use applications that are not for a subdivision or master plan can often
meet threshold for a traffic study; and
WHEREAS, after notice was given in accordance with applicable law, a public hearing was held on
January 9, 2014, before the Deschutes County Planning Commission and, on January 9, 2014, the Planning
Commission recommended approval of the text amendment; and
WHEREAS, the Board of County Commissioners considered this matter after a duly noticed public
hearing on June 4, 2014, and concluded that the proposed changes are consistent with the County's
Comprehensive Plan and that the public will benefit from changes to the land use regulations; now therefore,
THE BOARD OF COUNTY COMMISSIONERS OF DESCHUTES COUNTY, OREGON, ORDAINS
as follows:
Section 1. ADDING. DCC 18.116.310 is added as in Exhibit "A," attached and incorporated by

18.116.310 Traffic Impact Studies
A. For purposes of DCC 18.116.310, the transportation system includes public and private roads,
intersections, sidewalks, bike facilities, trails, and transit systems.
B. The applicant shall meet with County staff in a pre-application conference to discuss study
requirements, then generate the traffic study and submit it concurrently with the land use
application.
C. Guidelines for Traffic Impact Studies
1. All traffic impact studies shall be stamped and signed by the registered professional
engineer who is licensed in the State of Oregon and is otherwise qualified to prepare
traffic studies.
2. The County Engineer shall determine when the report has satisfied all the requirements of
the development's impact analysis. Incomplete reports shall be returned for completion.
3. The following vehicle trip generation thresholds shall determine the level and scope of
transportation analysis required for a new or expanded development.
a. No Report is required if there are fewer than 50 trips per day generated during a
weekday.
b. Site Traffic Report (STR): If the development or change in use will cause the site to
generate 50-200 daily trip ends, and less than 20 peak hour trips, a Site Traffic Report
may be required at the discretion of the County Engineer.
c. Traffic Impact Analysis (TIA): If the development or change in use will generate
more than 200 trip ends and 20 or more peak hour trips, then a Traffic Impact
Analysis (TIA) shall be required.
4. The peak hour shall be the highest continuous hour of traffic measured between 4:00 and
6:00 PM, unless site trip generation characteristics warrant consideration of alternative
periods as determined by the County Engineer. (An example would be a use with a high
7:00 and 9:00 AM peak and a low PM peak such as a school.)
D. Traffic Study Area
1. After consulting with other affected jurisdictions, the County Engineer shall determine
the impact analysis area.
2. The impact analysis study area shall include, at a minimum:
a. All site access points to the public roadway system via either a driveway or private
roadway;
b. Nearest intersecting collector or arterial roads to the development that would
experience an increase of25 additional peak hour trips;
c. Any other collector or arterial intersection requested by staff.
E. Study Time Frames
The analysis shall include the following time frames:
1. Existing conditions (including approved, but not yet built developments as identified by
the County Engineer);
2. Completion year of each significant phase of the development;
3. Five year forecast after build out for each phase of development or the final phase of
development.
4. Generators of large volumes of traffic (>5,000 daily and >500 peak hour trips), zone
changes, and any destination resort development will also require an analysis of traffic
conditions in a twenty-year horizon.
F. Minimum Study Requirements for a Site Traffic Report (STR)
The minimum study requirements for a Site Traffic Report are:
1. A vicinity map showing the location ofthe project in relation to the transportation system
of the area;
Exhibit A of Ordinance 2014-017 1

I. A vicinity map showing the location of the project in relation to the transportation system
of the area;
2. All ofthe elements of a STR;
3. Traffic signal progression analysis and interconnection if a new signal is proposed;
4. A response in the final report to any supplemental study issues identified by other
affected jurisdictions;
5. Appropriate traffic calming techniques if the project distributes trips to a residential local
road and is projected to increase the volumes on that road to a volume greater than 1,000
ADT;
6. Trip generation forecasts using data from the most recent edition of the Institute of
Transportation Engineers (ITE) Trip Generation Manual unless the County Engineer
approves an alternate data source;
7. Trip distribution assumptions are based on historical data, existing and future travel
characteristics, and capacity constraints;
8. A complete description and drawing ofthe proposed development.
9. Existing traffic volumes;
10. Existing and future levels of service, average vehicle delay and volume /capacity ratios
(V/C) for all intersections within the study area for conditions with and without the
proposed project;
11. Forecast traffic volumes with and without the development;
13. Safety analysis of the site accesses, include sight distance and operation characteristics;
14. Analysis of right and left turn lane warrants (Oregon Department of Transportation
(ODOT) standards);
15. Analysis of parking needs of the proposed development;
16. When needed, warrant analysis for traffic control devices;
17. Findings and conclusions including a recommendation of suggested potential mitigation
for off-site impacts and an evaluation of the effectiveness of those solutions.
H. Operation And Safety Standards.
The minimum operational and safety standards for use on Deschutes County's system are:
1. The minimum level of service for intersections and roads, during the P.M. Peak Hour,
shall be LOS "D" as determined by the most current published version of the
Transportation Research Board's Highway Capacity Manual.
2. For state highway intersections, the performance standard shall be determined by the
Oregon Highway Plan or ODOT-approved alternative standard or target.
1. The minimum sight distance for driveways and intersections is defined in AASHTO's
"GEOMETRIC DESIGN OF HIGHWAYS AND STREETS" and the AASHTO "Design
Guidelines for Very-Low Volume Local Roads « 400 ADT)".
I. Mitigation
1. The applicant shall be responsible to mitigate any safety or capacity problems that are
caused by their proposed development.
2. At the County Engineer's discretion, if there are pre-existing safety deficiencies and/or
capacity failures at relevant intersections or road frontages within the impact analysis

I. APPLICABLE CRITERIA:
Title 22, Deschutes County Development Procedures Ordinance
Title 23, Deschutes County Comprehensive Plan
Deschutes County Transportation System Plan (Section 3.7 of Comprehensive Plan)
Statewide Planning Goals
Transportation Planning Rule (Oregon Administrative Rule 660-012)
II. BASIC FINDINGS:
A. PROPOSAL: The applicant requests approval of moving the traffic study requirements
now found in DCC 17.16.115 and shifting them to DCC 18.116 and creating a Section
18.116.310, Traffic Study Requirements. The cross-references in DCC 18.124.080
Quality Services Performed with Pride
would be modified from DCC 17.16.115 to DCC 18.116.310 and DCC 17.16.115 would
also add a cross-reference to the new DCC 18.116.310. The reason for the change is
the County often requires traffic studies for land uses that are not subdivisions or master
plans, yet the requirements for traffic studies are now located in a section of the
development code that pertains solely to those two development proposals. A more
logical location would be DCC 18.116 which is not land use zone specific and already
includes many general transportation items such as standards for Class I and II road
projects, clear zones, off-street parking, and bicycle parking.
Selected portions of the traffic studies requirements have also been updated to reflect
changes in best practices and/or terminology to provide further clarity. Examples include
replacing references to a traffic engineer to Registered Professional Engineer; specifying
the time limits of the p.m. peak hour reference; and standardizing the County's Level of
Service (LOS) standard to D for all roadways instead of C for new County roads and D
for existing County facilities.
III. CONCLUSIONARY FINDINGS:
A. CHAPTER 22.12, LEGISLATIVE PROCEDURES
1. Section 22.12.010.
Hearing Required
FINDING: The Board finds this criterion has been met as public hearings were held before
the Planning Commission on Jan. 9, 2014, and the Board of County Commissioners on June
4,2014.
2. Section 22.12.020, Notice
Notice
A. Published Notice
1. Notice of a legislative change shall be published in a newspaper of
general circulation in the county at least 10 days prior to each public
hearing.
2. The notice shall state the time and place of the hearing and contain a
statement describing the general subject matter of the ordinance under
consideration.
FINDING: The Board finds this criterion has been met as notice was published in the Bend
Bulletin newspaper and described the proposal.
B. Posted Notice. Notice shall be posted at the discretion of the Planning
Director and where necessary to comply with ORS 203.045.
FINDING: The Board finds this criterion has been met as notice was posted in the bulletin
board in the lobby of the Deschutes County Community Development Department, 117 NW
Lafayette, Bend.
Exhibit C of Ordinance 2014-017 Page 2
C. Individual notice. Individual notice to property owners, as defined in
DCC 22.0B.010(A), shall be provided at the discretion of the Planning
Director, except as required by ORS 215.503.
FINDING: Given the land use in question does not apply to any specific property, no individual
notices were sent. The Board finds this criterion has been met.
D. Media notice. Copies of the notice of hearing shall be transmitted to
other newspapers published in Deschutes County.
FINDING: Notice was provided to the County public information official for wider media
distribution. The Board finds this criterion has been met.
3. Section 22.12.030 Initiation of Legislative Changes.
A legislative change may be initiated by application of individuals upon
payment of required fees as well as by the Board of County
Commissioners.
FINDING: The application was initiated by the Deschutes County Planning Division, which
received a fee waiver. The Board finds this criterion has been met.
4. Section 22.12.040. Hearings Body
A. The following shall serve as hearings or review body for legislative
changes in this order:
1. The Planning Commission.
2. The Board of County Commissioners.
FINDING: The Board finds this criterion has been met as the order of public hearings has been
followed,
B. Any legislative change initiated by the Board of County
Commissioners shall be reviewed by the Planning Commission prior to
action being taken by the Board of Commissioners.
FINDING: The Board find this criterion has been met as the Planning Commission public
hearing preceded the Board public hearing,
5, Section 22,12.050 Final Decision
All legislative changes shall be adopted by ordinance
FINDING: TA-13-2 is implemented by Ordinance 2014-001; the Board finds this criterion has
been met.
B. CHAPTER 23, DESCHUTES COUNTY COMPREHENSIVE PLAN
1, Chapter 3, Rural Growth Management. Section 3,6 Public Facilities and Services
Goal 1, Support the orderly, efficient and cost-effective siting of rural public
facilities and services.
Exhibit C of Ordinance 2014-017 Page 3
FINDING: The Board finds this criterion has been met as the amended traffic study
requirement sets the same Level of Service (LOS) standard for both new and existing facilities,
ensuring future roads and intersections are consistent with each other. The previous LOS C
standard for future facilities would have resulted in the potential overbuilding of County road
segments and/or intersections. By having LOS D as the performance standard for all existing
and future County road segments and intersections, the resulting road network will be orderly
and cost-effective.
2. Chapter 4. Urban Growth Management. Section 4.2 Urbanization Policies
Goal 4, To build a strong and thriving regional economy by coordinating
public investments, policies and regulations to support regional and state
economic development objectives in Central Oregon.
FINDING: The Board finds this criterion has been met as the text amendment will provide a
consistent performance standard for County roads. The traffic study requirements will ensure
economic development does not adversely affect the network of County roads and State
highways, but also will not result in the oversizing of adversely affected facilities.
3. Deschutes County Transportation System Plan
Goal 1, Coordination and Implementation, Policy 1.1c, Requirement of
conditions of approval on developments and transportation projects that
have a significant effect on the County's transportation system.
FINDING: The Board finds this criterion is met as the text amendment still defines a LOS
benchmark for the County's road system which in turn is used to determine whether a
development has a Significant effect or not.
4. Deschutes County Transportation System Plan (con't)
Goal 4, Arterial and Collector Road Plan, Policy 4.6, Deschutes County
shall manage the development process to obtain adequate street right-of
way and improvements commensurate with the level and impact of
development. New development shall provide traffic impact analysis to
assess those impacts and to help determine transportation system needs ...
FINDING: The thresholds for traffic analysis set in County code will remain unchanged so the
Board finds this criterion has been met.
5. Deschutes County Transportation System Plan (con't)
Goal 9, Performance Standards, Maintain a Level of Service "D" or better
during the peak hour throughout the County arterial and collector road
system over the next 20 years.
FINDING: The text amendment maintains the County Code requirement of a LOS D as the
performance standard for the County's arterial and collector system. The Board finds this
criterion has been met.
C. STATEWIDE PLANNING GOALS
1. Goal 1 , Citizen Involvement
Exhibit C of Ordinance 2014-017 Page 4
FINDING: The text amendment included workshops before both Deschutes County Planning
Commission (PC) and the Board of County Commissioners (Board). The text amendment also
included publically noticed public hearings before the PC and Board. The Board finds this
criterion is met.
2. Goal 2, Land Use Planning
FINDING: Oregon Revised Statute (ORS) 197.610 allows local governments to initiate post
acknowledgement plan amendments or changes to land use regulations. The County on Dec.
4, 2013, provided the Department of Land Conservation and Development (DLCD) with the
required notice 35 days prior to the first evidentiary hearing, which will be on Jan. 9, 2014. The
notice included the proposed changes with additions indicated by underlined text and text to be
eliminated indicated by strikethrough text. The text amendment was processed via the County's
development code procedures set for in Title 22, Chapter 22.12 for legislative amendments.
The Board finds this criterion has been met.
3. Goal 3, Agricultural Lands
FINDING: The text amendment is not proposing any changes to land use designations, so the
Board finds this criterion has either been met or is not applicable.
4. Goal 4, Forest Lands
FINDING: The text amendment is not proposing any changes to land use designations, so the
Board finds this criterion has either been met or is not applicable.
5. Goal 5, Natural Resources, Scenic and Historic Areas, and Open Spaces
FINDING: The text amendment is neither proposing any changes to land use designations nor
proposing roads through previously designated Goal 5 resources. Therefore, the Board finds
this criterion has either been met or is not applicable.
6. Goal 6, Air, Water and Land Resource Quality
FINDING: No development or land use changes are being proposed that impact air, water, or
land resource qualities. Deschutes County is not under any federal violations of air quality,
which often leads to traffic restrictions. Other areas of the County's code deal with protecting
air, water, and land remain in full force and effect. The Board finds this criterion has either been
met or is not applicable.
7. Goal 7, Natural Hazards
FINDING: The text amendment will ensure there is adequate capacity on the County and State
transportation system, allowing roads and highways to be used as evacuation routes and
ingress and egress for emergency vehicles. The Board finds this criterion has either been met
or is not applicable.
8. Goal 8, Recreational Needs
FINDING: The text amendment will ensure there is adequate capacity on the County and State
transportation system, allowing roads and highways to be used to access recreational sites
such as Mount Bachelor, the Cascade lakes, and public lands. The Board finds this criterion
has either been met or is not applicable.
Exhibit C of Ordinance 2014-017 Page 5
9. Goal 9. Economic Development
FINDING: A functioning transportation system is a basic need for economic development. The
text amendment will continue to provide clear and objective criteria for how County roads and
State highways need to operate and that a development must not result in degradation of the
transportation system. Mitigation is a required component in the County's traffic analysis
section. Therefore, the Board finds this criterion has been met.
10. Goal 10. Housing
FINDING: A functioning transportation system provides access to subdivisions and rural
homesteads. This goal pertains to urban or urbanizable lands. The proposed text amendment
will not result in any changes or elimination of residentially zoned lands in the County. The
Board finds this criterion has either been met or is not applicable.
11. Goal 11! Public Facilities and Services
FINDING: While roads are public, this goal pertains more to water and sewer services,
whereas transportation is treated explicitly under Goal 12. The County has an adopted
Transportation System Plan (TSP) and the traffic study requirements ensure any development
will be consistent with the TSP and its plans for public roads and highways. The Board finds
this criterion has either been met or is not applicable.
12. Goal 12. Transportation
FINDING: Deschutes County has an adopted and acknowledged TSP which will ensure an
orderly and efficient transition between rural and urban lands. The TSP at Table 5.3.T1 lists all
road and highway improvements for 2010-2030. The timeline for construction for each priority
project is High (0-5 years), Medium (6-11 years) and Low (11-20 years). There are 94 projects
overall, including roads, highways, bridges, sidewalks, etc. Of the 94 projects, 53 are County
roads only.
The current development code at DCC 17.16.115(H) sets a LOS D for existing County road
segments and intersections. For new roads or intersections the current development code sets
a performance standard of LOS C. The code defers to the Oregon Highway Plan (OHP)
mobility standards for state highways and intersections with state highways. Thus the proposed
text amendment would have no effect on projects on or intersecting with State highways.
Of the 53 County road projects listed in the TSP's Table 5.3.'-1, 47 are on existing roads or
intersections and thus would not be affected by the proposed text amendment as their mobility
standard would remain at LOS D.
TSP Table 5.3.T1 lists six projects as new roads. Of these half-dozen future improvements, five
are Low priority and one is a High priority. These six under the proposed plan amendment
would have their LOS standard changed from LOS C to LOS D. There is no funding in the
current adopted Capital Improvements Project (CIP) list for any of these six projects. The
County assumes these roads will be built as development occurs and currently there are no
land use applications in process or anticipated that would result in these improvements being
constructed. In other words, there is no imminent effect of making LOS D the standard for all
County roads and intersections, whether they exist or are planned.
The Board finds this criterion has been met.
Exhibit C of Ordinance 2014-017 Page 6
13. Goal 13, Energy Conservation
FINDING: This plan amendment does not affect the County's regulation of solar setbacks,
siting of small-scale windmills, land use or density, etc. The LOS will remain the same on
existing roadways so levels of allowed traffic volumes and delays at intersections would remain
the same. Typically, rural roads do not experience the wasteful stop and go traffic patterns that
urban facilities endure. The Board finds this criterion has been met.
14. Goal 14, Urbanization
FINDING: No land use plan designations, zoning designations, or map changes will result from
this plan amendment. The County TSP does not apply within any Urban Growth Boundaries
(UGB). The Board finds this criterion is met.
15. Goals 15-19
FINDING: The Board finds these criteria do not apply as the County lacks these lands
(Willamette Greenway, estuaries, coasts, beaches, etc).
D. TRANSPORTATION PLANNING RULE (OAR 660-012)
Plan and Land Use Regulation Amendments 660-012-0060
(1) If an amendment to a functional plan, an acknowledged plan, or a land
use regulation (including a zoning map) would significantly affect an
existing or planned transportation facility, then the local government must
put in place measures a provided in section (2) of this rule, unless the
amendment is allowed under section (3), (9), or (10) of this rule. A plan or
land use regulation amendment significantly affects a transportation
facility if it would:
(a) Change the functional classification system; or
FINDING: The proposed amendment will not result in any changes in the functional
classification system. The Board finds this criterion has been met.
(b) Change standards implementing functional classification system: or
FINDING: The proposed amendment will change the mobility standard for new County facilities
from LOS C to LOS D. The performance standard for new State highways and existing County
facilities will remain the same. The Board finds this criterion has been met.
(c) Result in any of the effects listed in paragraphs (A) through (C) of this
subsection based on projected conditions measured at the end of the
planning period identified in adopted TSP ...
(A) Types or levels of travel or access that are inconsistent with the
functional classification of an existing or planned transportation
facility;
FINDING: The proposed amendment will not change the mix of vehicles on County roads or
State highways nor will it change the volumes of traffic on the County and State system. The
Exhibit C of Ordinance 2014-017 Page 7
County's and State's access management rules set forth in DCC 17.48.090 and the Oregon
Highway Plan (OHP) remain unchanged. The Board finds this criterion has been met.
(8) Degrade the performance of an existing or planned
transportation facility such that it would not meet the performance
standards identified in the TSP or comprehensive plan; or
FINDING: The proposed amendment will not degrade the performance of an existing
transportation facility; it will change the performance standard for planned transportation
facilities. However, changing the standard is not degrading the standard; it is merely resetting
the standard. Additionally, changing performance standards is allowed under OAR 660-012
0060(2){c). The Board finds this criterion has been satisfied.
(C) Degrade the performance of an existing or planned
transportation that is otherwise projected to not meet the
performance standards identified in the TSP or comprehensive plan.
FINDING: The proposed amendment will not further degrade the performance of an eXisting
transportation facility. All transportation facilities in the adopted TSP that were projected to fail
over the 20-year life of the plan also have planned improvements in Table 5.3.T1 to mitigate
those failures. The Board finds this criterion has been satisfied.
(2) If a local government determines that there would be a significant effect,
then the local government must ensure that allowed land uses are
consistent with the identified function, capacity, and performance
standards of the facility measured at the end of the planning period
identified in the adopted TSP through one or a combination of the remedies
listed in (a) through (e) below...
(a) Adopting measures that demonstrate allowed land uses are
consistent with the planned function, capacity, and performance
standards of the facility.
FINDING: The County will maintain its land use designations, functional classifications, and
access management standards while modifying the performance standards for County roads as
allowed under OAR 660-012-060(2)(c) below. The Board finds this criterion has been met.
(b) Amending the TSP or comprehensive plan to provide
transportation facilities, improvements or services adequate to
support the proposed land uses consistent with the requirements of
this division...
FINDING: The County did not choose this remedy option. The Board finds this criterion is not
applicable.
(c) Amending the TSP to modify the planned function, capacity or
performance standards of the transportation facility.
FINDING: The County will modify the performance standard for future County facilities from
LOS C, the current standard, to LOS D. The performance standard for eXisting County facilities
will remain at LOS D. This will result in a consistent standard for both planned and existing
County facilities. The County TSP Goal 9 (Performance Standards Goals and Policies) sets a
goal of "[M]aintain a level of service D or better during the peak hour throughout the County
arterial and collector road system over the next 20 years." Goal 10 is "[M]aintain the current
Exhibit C of Ordinance 2014-017 Page 8
arterial and collector system in the County and prevent degradation of the capacity of the
system." The performance standard for State highways and intersections with State highways
will remain unchanged. The Board finds this criterion has been met.
(d) Providing other measures as a condition of development or
through development agreement or similar funding method,
including, but not limited to, transportation system management
measures or minor transportation improvements...
FINDING: The County did not choose this remedy option, but the County's development code
does require an applicant to mitigate a development's effects. The Board finds this criterion is
not applicable.
IV. CONCLUSION:
The proposed text amendment to move the traffic study requirements from the Subdivision
section of the code to the Supplemental provision section makes logical sense. Many site plans
for uses that are not subdivisions or master plans still generate 50 or more weekday trips, which
is the County's baseline for requiring a traffic study. The TPR gives local governments the
discretion to modify the performance standards for their facilities. The County having a single
LOS benchmark for all County facilities will result in a consistent level of improvements needed
to mitigate any adverse affects of proposed land uses.
