Tumalo Rural Community.
A. General.
1. Background — Historical.
Tumalo is located in the north central portion of Deschutes County, less than 3 miles northwest of
the city limits of Bend. Situated at an altitude of approximately 3,200 feet, the community of
Tumalo lies in the middle portion of the Upper Deschutes River Basin (river mile 157). The
commercial core of Tumalo lies on the alluvial bowl bounded by the Laidlaw Butte on the west and
the bluff of he Deschutes River canyon on the east. The Deschutes River bisects the community.
Originally named Laidlaw, Tumalo was platted by the Laidlaw Townsite Company in 1904. The
development of Tumalo began in 1899 with incorporation of the Three Sisters Irrigation Company.
Under the Carey Act, they made plans to divert water from Tumalo Creek and the Deschutes River
in order to irrigate 60,000 plus acres of desert land. Town founder, A.W. Laidlaw of Portland, and
his investors believed that Tumalo would become the heart of Central Oregon. There was reason to
be optimistic due to the fact the railroad was coming north up the Deschutes River Canyon, which
would undoubtedly follow the river into their newly platted town, and the proposed railroad to be
built up the North Santiam River and across the mountains would surely guarantee the town's
success. Neither of these projects came to fruition.
Out of nearly 900 lots platted, a third were sold by 1907. In those early days, Tumalo had a weekly
newspaper, a barbershop, a two-story hotel, two lawyer offices, a wallpaper company, a bakery, two
feed stores and a bank, for example. As the town grew, it became its own voting precinct with 65
registered voters to Bend's 66 voters in 1906. By 1909, Laidlaw, being called Tumalo on occasion,
still had hopes of being the junction of the two railroads, the new "metropolis" of Central Oregon.
However, at the time the Columbia Southern Railroad still ended in Shaniko, and the Corvallis and
Eastern rails were still stalled at the foothills on the western side of the Cascades, where they had
been for approximately 15 years. With the announcement that the railroad was coming to Bend not
Laidlaw, Bend had moved ahead in population by 1910. As a result, the population in Laidlaw
decreased to 250 people and many businesses moved to Bend. The small town was known as
Laidlaw for only six years when the Laidlaw post office was closed in 1913. The post office
eventually reopened in 1923 as the Tumalo post office and thus the name of the town was forever
changed.
2. Background - Population and growth.
Page 1 of 12 — Exhibit "A" TO ORDINANCE 2005-017 (4/25/05)
EXHIBIT "A"
The population for Tumalo has been extrapolated from four sources: the 1990 Census, the
Deschutes County Unincorporated Land Use Inventory (October 1995), and the Residential/Vacant
Lands map generated by the Deschutes County GIS data. The fourth source is a refinement of the
1995 Land Use Inventory projection for Tumalo contained in the Deschutes County Non -Urban
Population Capacity Projection (November 8, 1996).
In review of the 1990 US Census for Tumalo area totaled approximately 325 persons. Historical
population data for Tumalo have not been collected. However, the Tumalo Elementary School has
experienced an influx of younger couples with children replacing retirees who have moved out of
the area. The Turnalo elementary school has approximately 301 students at the present time with a
capacity of approximately 400 serving grades K through 5th. According to the Deschutes County
Land Use Inventory (October 1995) Turnalo had 155 developed lots. Using 1990 Census data of
2.54 persons per household, the population figure would be 393. Again, this does not take into
account percentages of retirement population and second homes in the Tumalo area. According to
the GIS Parcel basemap (Assessors data) the developed lots in Tumalo equal 172. Using the 1990
Census figure of 2.54 persons per household, this population figure is approximately 436.
The rate of future population growth in Tumalo is difficult to estimate because growth is limited
due to the substandard platted lots of the Laidlaw Platt as well as the difficulty in extrapolating data
for the specific boundary of Tumalo. Deschutes County projects a countywide growth rate of 4.5
percent until the year 2000. Recent estimates for all unincorporated areas of Deschutes County
(excluding unincorporated urban growth boundary lands of Sisters, Redmond and Bend) indicate a
growth rate of 4.8% annual growth between 1990-1995.
3. Background - Periodic review.
In the fall of. 1994, the Land Conservation and Development Commission adopted a new
administrative rule, OAR 660.22, Unincorporated Communities. As part of 1996-97 periodic
review, the County updated the Comprehensive Plan and implementing regulations for Tumalo to
comply with the rule.
4. Rural Community.
Tumalo meets the definition of a Rural Community because it is primarily a residential community,
which also has a school, church, and a handful of local businesses that serve the community, the
surrounding rural area or persons traveling through the area. The comprehensive plan designates
Tumalo as a Rural Community and provides for its growth and development accordingly.
5. Turnalo Rural Community boundary.
The 1979 Deschutes County Comprehensive Plan designated Tumalo a Rural Service Center, a
Goal 3 and 4 exception area, consisting of 491 acres and 288 tax lots. The 1979 Tumalo Rural
Service Center boundary included the Laidlaw Plat, the southeast flank of Laidlaw Butte north of
Bailey Road, the area cast of the Deschutes River on the north and south sides of Tumalo Road, six
lots of the Winston Ranch subdivision on the east bluff of the Deschutes River canyon and seven
parcels located north of Putnam Lane.
During the 1997 update, the Tumalo Rural Community boundary was amended in the following
ways to include 504.11 acres and 321 tax lots (See Map A).
a. A parcel comprising ten acres was the subject of a zone change, plan amendment and minor
partition in 1980, File #ZC-PA/80-1. This parcel is located approximately 1/4mile north of the
existing boundary on the between Cline Falls Highway and the west bank of the Deschutes
River. The plan designation for this area was changed from Rural Service Center to Rural
Residential Exception Area.
b. An area consisting of 33 lots of the Deschutes River Homesites subdivision was changed from a
plan designation of Rural Residential Exception Area to Rural Community- Residential 5 acre.
In addition, the strip of land that is located between Cline Falls Highway and the Deschutes
Page 2 of 12 — Exhibit "A" TO ORDINANCE 2005-017 (4/25/05)
EXHIBIT "A"
River that links the previous Tumalo Rural Community boundary to the lots adjacent to Beaver
Lane was included within the boundary and designated Residential 5 acre.
c. One tax lot north of Putnam Lane on the west side of Hopper Road which comprises the
northern lot of the Rockwood Subdivision not included with the other seven lots that are
located within the boundary. The plan designation for this area was changed from Rural
Residential Exception Area to Residential 5 acre.
d. The community boundary was refined to coincide with parcel lines along the east rim of the
Deschutes River canyon and along the east channel of the Deschutes River. The plan
designations for these adjustments were changed from "Residential -5 acre" to Rural Residential
Exception Area and Agriculture. The south boundary of the community was refined to coincide
with the southern extension of the TuR5 and TuR zoning designations in the area of designated
Floodplain.
In 1999, the boundary of the community was revised to exclude tax lots 2301, 2300 and 2600 that
were inadvertently excluded from the mining processing operations conducted by Bend Aggregate
and Paving for many years. These parcels were mistakenly included in the community boundary in
1997. The community boundary now without these tax lots includes a total of 318 tax lots. Each of
the community maps in the comprehensive plan was revised in 1999 to reflect this boundary
change.
B. Land use planning.
I . Existing land uses.
The predominant land use in Tumalo is single-family residences. Commercial land uses include a
market, restaurants, real estate offices, a small commercial/retail complex, and various other small-
scale retail businesses located in the core of the community along Cook Avenue. There is a fire
station, an irrigation district office, a church and an elementary school.
Land bordering Tumalo is zoned Exclusive Farm Use (EFUTRB) Tumalo/Redmond/Bend
Subzone, Multiple Use Agriculture (MUA10 - 10 acre minimum lot size), Floodplain (FP) and
Surface Mine (SM). The Deschutes County Comprehensive Plan designates EFU land for
Agriculture uses and MUA10 and RRIO land for Rural Residential uses. The EFU land
surrounding Tumalo is employed in large -lot, irrigated agricultural uses, whereas the MUA10 land
is parcelized and developed with rural residences and small-scale agricultural uses.
A land use inventory using the County Assessor's data (GIS parcel basemap) is shown in Table B.

2. Comprehensive Plan designations.
The 4997- Deschutes County Comprehensive Plan for the Tumalo Rural Community has the
following fwe six comprehensive plan designations (See Map B).
a. Residential District. At the time of adoption, the boundary of the Residential district coincided
with the boundary of the old Laidlaw Plat including the Deschutes River Homesites plats
between Riverview Avenue and the Deschutes River. It also includes the area surrounding the
Bend Aggregate site south of Highway 20. It is intended to accommodate higher density
residential uses
b. Residential 5 -Acre District. The lands designated Residential -5 acre minimum included the
larger parcels of land to the east across the Deschutes River and to the west on the slope of
Laidlaw Butte. This plan designation is intended to remain in large parcels to maintain the rural
character of the community.
c. Commercial District. In general, the Commercial plan designation extends north from the
intersection of Cook Avenue and Highway 20 to 3rd Street between Wood and Wharton
Avenues. The Commercial lands also comprises a portion of land west of Highway 20 between
5th and 8th Streets. The commercial plan designation was intended to accommodate a mixture
of small-scale commercial and limited industrial uses that serve the rural community of
Tumalo. The core commercial area was intended to focus on the area adjacent to Cook Avenue
north of Highway 20.
The Commercial Land designation was expanded to accommodate a section of land between
Cook Avenue and Wharton Avenue that extends south to Highway 20. This area includes the
"Tumalo Mall", an existing commercial/retail complex. The use of this building has been
authorized as a nonconforming use (1986), and subsequent site plan alteration in 1987/88. The
purpose of the commercial lands expanding to include this parcel is to bring the uses specified
in the previous ' land use decisions into compliance with the uses allowed in the commercial
zone. This complex contains one existing business which occupies 2/3 of the building.
d. Research Development District (RD). This plan designation contains two parcels in one
ownership located on the southeast slope of Laidlaw Butte to the west of Tumalo. This plan
designation was originally created to accommodate a research and development site and its
associated uses that predated the county 1979 -zoning ordinance that would be compatible with
the rural character of the area.
e. Floodplain District (FP). This plan designation contains the previous Floodplain designation
that follows the channel of the Deschutes River that bisects the Turnalo Rural Community. The
Floodplain Zone is identified by the Federal Insurance Administration as areas of special flood
hazard in the report entitled "The Flood Insurance Study for Deschutes County, Oregon and
Incorporated Areas," dated August 16, 1988.
f. Industrial District MD. The Tul plan designation was established to recognize nonconforming
industrial uses related to surface mining activities located outside of the Surface Mining zone in
the Tumalo Rural CommunLty-

C. Public facility planning.
1. Special Districts: Tumalo Rural Community is served by the following special districts. (1) Laidlaw
Water District; (2) Deschutes County Rural Fire Protection District #2; (3) Redmond School
District #2J; (4) Tumalo Iffigation District; and (5) Tumalo Town Ditch.
a. Water.
The area previously identified as the Tumalo Rural Service Center (RSC) has two water
sources.
The Laidlaw Water District serving the area identified as the old Laidlaw Plat, and the area
described as T16S R12E section 29 (WI/2 SWI/4), section 30 (El/2 SW 1/4), (SW 1/4 SE 1/4),
section 3 1 (NE 1/4, N 1/2 SE 1/4).
The Tumalo Town Ditch is the original source of water which has water rights dating back to
1924 and 1938. The system consists of 3 miles of ditch that begins near the bridge at Tumalo
State Park, and runs along the river as a ditch crossing Bailey Road at the Tumalo Feed
Company Restaurant, continues under Highway 20 to the commercial district of the Tumalo
community. The Tumalo Town ditch is used for inigation purposes only, serving
approximately 35 customers.
During the 1997 plan update, the Oregon Department of Water Resources commented that there
is an abundant supply of potable water in multiple water bearing zones based upon a report
prepared by a geologist for the Oregon Department of Geology and Mineral Industries,
"Geology and Mineral Resources Map of the Tumalo Dam Quadrangle". Limitations are
imposed by the lack of capacity of domestic pumps and not the capacity of the aquifer. The
department has not identified Tumalo Rural Community as a groundwater limited or
groundwater critical area. The Laidlaw Domestic Water District currently depends on two
groundwater wells. The District's groundwater source does not exceed current EPA maximum
contaminant limits. No treatment is performed; none has been required by the state Health
Division. A proposed EPA groundwater disinfection rule would require continuous
disinfection of the water supply. The area in the Tumalo Rural Community that is outside the
Page 6 of 12 — Exhibit "A" TO ORDINANCE 2005-017 (4/25/05)
EXHIBIT "A"
District's boundary relies on individual wells for drinking water. The Water Resources
Department routinely approves new groundwater wells in this area of the Tumalo Rural
Community.
b. Sewer.
Tumalo does not have a community sewer system or a sewer facility plan. Land uses in the
Tumalo Rural Community rely on on-site sewage disposal systems of all ages and descriptions,
ranging from newer sand -filter systems to old drainfields. In some cases on-site systems are
insufficient for cur -rent needs. According to the Environmental Health Division, past
experience has indicated most of the soils in the area would fall under the category of rapidly
draining soils. Based upon the most restrictive parameter onsite administrative rules would
require a minimum lot size of one-half acre per single-family dwelling. This standard is based
upon a projected sewage rate not to exceed 450 gallons per day. This is termed the loading rate
pursuant to OAR 340-71-290(3)(c) and 340-71-275(3). Because of the alluvial soil profile
(rapidly draining soils) a standard septic system is not feasible on smaller lots. It is often
necessary to install a relatively expensive sand -filter system in order to obtain development
permits for new development or for alterations to existing development. There are a few tax
lots that cannot be developed or redeveloped, because they are too small to accommodate any
approved on-site sewage disposal system.
The County plan and zoning regulations restrict the type and intensity of allowed uses to those
which can be served by a DEQ approved on-site sewage disposal systems. The County does
not allow uses or densities that cannot obtain approval for a DEQ approved on-site system. In
addition, County -zoning regulations set minimum lot sizes to ensure the on-site systems do not
exceed the capacity of the land. Accordingly, the Environmental Health Division has stated
that the minimum loading rates are addressed in the DEQ on-site rules and the minimum lot
size requirements in the zoning ordinance. Due to these provisions, a public facility plan is not
necessary.
c. Other.
During the 1997 update, the community expressed strong support for retaining the existing fire
station in the rural community of Tumalo. The Planning Commission recommended a policy
encouraging the continued presence of a fire station in Tumalo. However, the Board of County
Commissioners understands that such a specific policy would be beyond its jurisdiction and
control. The Board has addressed the community's concerns about fire protection in Tumalo by
adopting a more general policy statement. Inclusion of this policy statement in the county's
comprehensive plan should not be misconstrued as an endorsement for or against a fire station
in the community but a mere finding that at this point in time, a large number of Tumalo
residents believe that a fire station presence is necessary.
2. General public facility planning policies.
a. Residential minimum lot sizes shall be determined by the capacity of the land to accommodate
available water and sewer facilities, in order to protect and promote public health and safety and
to provide the efficient public facilities and services.
b. The County shall encourage quality fire protection in the rural community of Tumalo.
c. The County shall encourage early planning and acquisition of sites needed for public facilities
(e.g. school, roads, water supply facility).
d. The County shall encourage all development within the Laidlaw Water District to connect to
the system.
e. The County shall support replatting of lots in the area comprising the Laidlaw Plat and outside
the lands designated commercial to create lots large enough to accommodate a DEQ approved
on-site sewage disposal system.
f. The County shall support the protection of the Tumalo Town Ditch easement and its
distribution system.
Page 7 of 12 — Exhibit "A" TO ORDINANCE 2005-017 (4/25/05)
EXHIBIT "A"
g. The County shall support the development and management of the domestic water system for
the Tumalo community so that cumulative development will not result in public health hazards
of adverse environmental impacts that violate state or federal water quality regulations.
D. Transportation planning.
1. Background - Transportation in Tumalo.
The Transportation plan addresses the transportation concerns of the Tumalo community. The plan
meets the requirements of the state Transportation Planning Rule - OAR Chapter 660, Division 12,
by designating a network of local roads, sidewalks and bikeways with associated road development
standards.
a. Community transportation goals.
The livability of the Tumalo community depends on the ability of the transportation network to
provide safe and convenient access in the residential and commercial areas and to the Tumalo
elementary school. The community reached consensus on the following transportation goals:
I . Improve the access from Cook Avenue to and across Highway 20
2. Reduce truck traffic through the community
3. Provide safe pedestrian walkways in the commercial core and to the school
4. Provide road standards that are practical and cost effective to construct and maintain
5. Provide shoulders on county roads
b. Community profile.
Tumalo is a rural community near Bend with a mix of residential, commercial, and nearby
employment, including gravel quarries and a high-tech research company. It functions as a
bedroom community for Bend. Historical population data have not been compiled. The 1990
US Census for the Tumalo area totals approximately 325 persons. County Assessor's data
show 172 dwellings within the Tumalo community boundary. According to the Deschutes
County Land Use Inventory (October 1995) Tumalo had 155 lots. Using the 1990 Census data
of 2.54 persons per household, the population figure ranges from approximately 393 to 436.
According to the Redmond School District, the Tumalo Elementary School has experienced an
influx of younger children in recent years. Although figures indicating the demographic mix
for the Tumalo area are not available, the population appears to be a mix of families and
retirees, with an average or above number of children (nondrivers).
c. Collision data.
There were 3 8 reported collisions on Highway 20 near Tumalo during the I 0 -year period from
1986 to 1995. There were 42 injuries and I fatality. Of the 38 crashes, 17 occurred at
intersections, with seven at Cook Avenue and eight at 7th Street. The majority of crashes (27)
were during daylight. Eight incidents involved a wet surface and 10 involved trucks; no
pedestrians or bicyclists were involved. These numbers place this segment of Highway 20
below the state average for accident rate.
d. Constraints on the transportation system.
I Topographic Features: Tumalo is located on the valley floor of the Deschutes River
canyon, bounded by rimrock on the west and east. Laidlaw Butte forms the other
significant topographic feature to the west of Tumalo. The rimrock and river limit the
opportunities for a network of continuous streets.
2. Transportation Features: Highway 20 runs north-northwest through Turnalo and limits
east -west street connections. There are 3 accesses to the highway: 5th Street, 7th
Street/Bailey Road, and Cook Avenue/O.B. Riley Road.
Pavement runoff is handled by direct absorption into the soil since there is no community
stormdrain or sewer system. This affects street design especially the use of curbs, paved
surfaces, and landscaping. Special attention must be given to drainage needs and runoff into
the Deschutes River.

2. Inventory of existing transportation facilities.
This section contains an inventory of the existing public roads and pedestrian and bicycle facilities
in Tumalo. These data were gathered primarily from the County Department of Public Works
database supplemented by site visits and aerial photographs.
a. Roads.
The essential component of the region's transportation system is U.S. Highway 20 which runs
diagonally through the community. Highway 20 has three lanes, a travel lane in each direction
and a continuous two-way center left -tum lane. The traffic count at the intersection of Highway
20 and Cook Avenue in 1996 was 7600 average daily traffic (ADT). The posted speed on
Highway 20 through Tumalo is 55 mph. Intrastate truck traffic and local truck traffic serving
nearby mining operations comprise a significant percentage of the traffic mix.
O.B. Riley Road, which is outside the community boundary, is a rural arterial which intersects
Highway 20 from the south directly across from Cook Avenue. This road bisects the gravel
mining operation that abuts Highway 20.
County collector roads include Bailey, Cline Falls, Cook, and Tumalo which all intersect
Highway 20 in the central portion of Turnalo. Cline Falls feeds into Tumalo from the north,
Tumalo Road from the east, and Bailey Road feeds into the community from the south. There
are approximately 4.7 miles of roads in Tumalo.
Table DI (Inventory of Existing Roads), is organized by functional classification, road name
and alphabetical order. The available (ADT) counts provided by the county and state are listed.
The public roads in Tumalo (see Map DI) range in pavement width from 20 feet to 24 feet.
Some streets (e.g., Riverview Ave.) are in poor condition (i.e. cracking and pot holes). Most
unpaved roads need grading and a fresh layer of gravel.
b. Pedestrian facilities.
There are no sidewalks or trails in Tumalo. The bridge on Tumalo Road has a walkway on its
north side. There are two designated crosswalks, one on Cline Falls Road on the north side of
the Tumalo Road intersection and the other on Cook Avenue on the north side of the 4th Street
intersection. Cline Falls Road is signed for 20 mph if children are present because of the nearby
elementary school (the normal speed limit is 35 mph). All other pedestrian travel is on
roadways with narrow or no shoulders.
Except for the school grounds, Tumalo lacks public space such as a park, square or commons to
which pedestrians could be attracted. There is undeveloped public access to the river from
Turnalo Road. The primary trip attractors are the school, a church and the small commercial
area (gas station, market, and restaurant). There is also a restaurant on the west side of Highway
20.
c. Bicycle facilities.
Highway 20 has a four -foot paved shoulder bikeway. All other bicycle travel is on shared
roadways. Cline Falls Road and Cook Avenue are popular recreational routes. There are
bicycle racks at the school.
3. Future transportation needs.
A rural community such as Turnalo, located on a major highway, requires a transportation network
that can accommodate local, commuter, regional, and interstate traffic without detracting from the
community's livability and rural character. Accomplishing this goal requires integrated street,
bicycle and pedestrian networks, appropriate street standards, and safe access to the Highway 20
corridor.

EXHIBIT "A"
The Tumalo transportation plan is based on conventional road functional classifications; or: arterial,
collector and local roads. It establishes the roles and development standards appropriate to each
type or road. The design of arterial and collector roads gives priority to through traffic over access
to adjacent land uses. On local roads the emphasis is on access to adjacent land uses.
a. Transportation network plan.
The transportation network plan for Tumalo identifies where the roads need to be improved and
where pedestrian and bicycle facilities are warranted. The network plan has three components:
roads, sidewalks and bikeways.
I . Roads. Central Tumalo is a relatively compact area without need for additional public
streets; infill will access existing streets. For the roads depicted on Map D2, planned
improvements take advantage of existing public rigbt-of-way, where it exists. Lands in the
low density areas are served by existing public right-of-way which are unpaved, non -
maintained public roads (Beaver Lane, Putnam Lane and Hopper Road) and private drives
(Research Road, Winston Loop Road). Map D2 also depicts the roads that need
improvement to serve the local road network and through traffic corridors.
2. Sidewalks.
Map D2 shows where sidewalks are needed for safety and identifies a potential opportunity
for a trail extending south along the west side of Deschutes River. In Tumalo, a sidewalk
network is needed along Cook Avenue, 4th, 5th, 7th and 8th streets to access the school and
provide safe places for people to walk in the commercial area as it develops.
Sidewalks are usually separated from the road by a curb and gutter, which function as part
of the stonn drain system. Tumalo does not have a storm drain system. As an alternative,
sidewalks in Tumalo shall be constructed without curbs and gutters and set back from the
road surface behind a drainage swale. This type of sidewalk design is adequate, less costly
and is consistent with the rural character of Turnalo.
A drainage swale is a broad, manmade depression running parallel to the right of way
between the roadway and the sidewalk, where water can drain into the ground. The swale
also provides room for signs, mailboxes, and snow storage, leaving the sidewalk free of
obstructions. Street trees should not be planted in drainage swales where they will conflict
with existing or planned utility lines, whereby the tree roots may damage pipes and
conduits complicating repair work.
3. Bikeways.
Two types of bikeways are appropriate in rural areas. A shared roadway for local roads
with low traffic volumes and speeds, and a paved shoulder bikeway for collectors and
arterials with higher volumes and speeds or significant truck traffic. In Tumalo, paved
shoulder bikeways are needed on Cline Falls Highway/Cook Avenue, Tumalo Road and
Bailey Road which are County collector roads, including a bicycle connection from O.B.
Riley south to Tumalo State Park (see Map 132).
4 Highway 20.
The intersection of the Highway 20 and Cook Avenue has been identified by the
community as a traffic safety hazard. The Oregon Department of Transportation (ODOT)
will have the lead authority to develop a solution to the realignment of this intersection.
Preliminary designs have been presented to the Tumalo community. The County will work
with ODOT to provide a solution to this intersection and to the connecting network of
County roads which includes the realignment of O.B. Riley Road through the existing
mining operation on the south side of Highway 20.

Projects to complete the transportation network plan are listed in Table D2. The tables list
the type of improvement and the associated cost. The priorities are based upon perceived
need while being flexible to grant funding or development opportunities.
b. Road development standards.
In recent years, urban street development standards were required in unincorporated
communities within the county. The urban standards required 36 feet of pavement, with
curb -tight sidewalks, curbs and gutters. It became evident that this standard was not practical or
necessary in Tumalo. None of the existing roads in Tumalo meet this standard. The cost to build
to this standard prohibited local residents from forming Local Improvement Districts (LIDs). In
addition, people resisted the urban street profile because it did not fit with the community's
preference for a rural appearance. The road standards are intended to decrease the cost of road
improvements and to remove barriers to the formation of LIDs, for improving local roads.
There are sound traffic engineering principles that support reduced street standards. The State
Transportation Planning Rule (OAR 660.12.045(7)) directs local governments to establish
standards for local streets that minimize pavement width and total right-of-way consistent with
the operational needs of the facility.
Excessive standards increase the costs of construction, use up valuable land, encourage
inappropriate traffic volumes and speeds and create a problem channeling stormwater runoff. In
Tumalo, full urban road standards are not needed because the traffic volumes and speeds on
roads in the community are low compared to city streets. Many roads serve only a few
residences. However, existing County rural road standards are not adequate to serve the
densities and variety of uses found in Turnalo. Local businesses and the elementary school
generate more local trips than normally found in the rural county.
The Turnalo Rural Community road development standards were developed in coordination
with the community planning process, the Oregon Department of Transportation (ODOT)
Region 4, the state Bicycle and Pedestrian Program and with the County Planning Division and
Public Works Department. These road standards are consistent with ODOT and the American
Association of State Highway Traffic Officials (AASHTO) standards for rural communities.
They apply to public rights-of-way other than the state highway which is under state
jurisdiction.
