STREET AND ALLEY STANDARDS
A.
Purpose
Street
standards within Station Communities provide for pedestrian orientation while
ensuring motor vehicle and emergency service access and circulation. Street
widths and lane configurations within Station Communities may be narrower,
or in some instances wider, than elsewhere in the City to accommodate the
design of smaller lot developments and its related density and traffic demands,
to provide for traffic calming measures, to provide for landscape strips between
the curb and the sidewalk, and to provide for other measures and standards
consistent with the overall purpose of transit-oriented development. In addition,
to ensure access to residential and commercial development built to higher
densities found in Station Communities, alleys are an essential element of
the circulation system in certain areas; consequently, Station Community Districts
may require alleys. Further, access to lots within Station Communities may
be held to a different standard than elsewhere in the City to ensure maximum
connectivity between adjacent developments within the Station Community, to
optimize the utilization of developable land, and help develop a safe and
secure neighborhood where walking and bicycling is a preferred method of travel.
Where development occurs in previously undeveloped land or in other areas
where possible, streets and alleys should be laid out to create a grid system
but in any case shall be laid out with block lengths limited to easily walkable
distances.
B.
Standards (1)
1.
Streets within development projects in Station Community Planning
Areas shall be configured to meet the urban design of the development, the
traffic volume and characteristics of the density and uses within the development,
and the on-street parking demand of the uses. Final street cross-section (number
and width of lanes, parking on one or two sides, etc.) and right-of-way widths
shall be determined based on the roadway cross sections submitted by the applicant
during Development Review; except that individual components shall have the
following performance standards and requirements:

travel lane within a right-of-way of twenty feet (20').
(14)
Construction Materials: Local streets and minor collectors may be
constructed of either Portland Cement Concrete or Asphaltic Concrete with
a structural cross section meeting or exceeding the engineering standards
of the City. Portland Concrete is the preferred material for local streets
and minor collectors is the required material to be used for all curbs
and gutters. Alleys shall be constructed of either Portland Cement Concrete
or Asphaltic Concrete with a structural cross section meeting or exceeding
the engineering standards of the City. All streets and alleys shall include
all signs and on-street thermoplastic markings necessary to properly operate
the street or alley as designed; including, but not limited to, lane markings,
bicycle striping and markings, no parking signs, stop signs, traffic signals,
curb markings, parking stall markings, and all other necessary signs and
markings. (Amended by Ord. No. 4930/7-00.)
(15)
Public Utility Easement Width and Requirements: 8 feet;
Except
as provided in Section 138.IV.C.5., all public utility distribution and
service connections within a development project shall be placed underground
using one of the three location options:
(a)
Under the sidewalk; where whole blocks are constructed at the time of
development or the maximum setback of the district is less than ten
feet (10') for the adjacent type of development.
(b)
Back of sidewalk; where the maximum setback of the district is ten feet
(10') or more; or
(c)
Within the alley right-of-way.
b.
Collector and Arterial Streets, Minimum Number, Lane Width and Median Requirements:
(1)
The standards and requirements of Local Streets and Minor Collectors shall
apply; except that:
(a)
Major collector streets shall be constructed using a three (3) lane
section with two (2) travel lanes at least ten feet (10') in width,
a center median/left turn lane eleven feet (11') in width and the left
turn storage lane length sized to meet the demand as determined by the
traffic engineering study.
(b)
Collector and arterial streets designated as a transit street or planned
transit street shall construct the curbside lane to be twelve (12')
wide without reducing the minimum widths of any other component within
the right-of-way.
(c)
Collector and arterial streets shall provide six foot (6') on-street
bicycle lanes in both travel directions.
(d)
Traffic calming measures shall be allowed on all streets within SCPAs
and shall be required as the result of the Development Review process
where warranted by the results of the traffic engineering and pedestrian
circulation study.
(e)
Major collector and arterial streets shall be constructed of Portland
Cement Concrete.
(f)
Arterial street travel lane numbers, widths, median and turn lane requirements
shall be sized and constructed according to the results of the traffic
engineering study and engineering standards required elsewhere in the
City except where those standards conflict with specific provisions
of this subsection the provisions of this subsection shall prevail.
(g)
Major collector and arterial streets controlled by traffic signals shall
provide a sidewalk intersection of sufficient size and design to afford,
at a minimum, AASHTO Urban Street Pedestrian Queuing Area Level of Service
"D" (7 square feet /person), and a pedestrian refuge within the median
area of a street of three (3) or more lanes to provide, at a minimum,
AASHTO Urban Street Pedestrian Queuing Area Level of Service "C" (10
square feet /person). Queuing area size shall be determined based on
the traffic engineering study using these minimum Levels of Service.
___________________
(1)
Where any street within a SCPA is under Washington County jurisdiction at the
time of development application, the street design
is subject to County Road Standards and the approval of the County Engineering
Division. However, the components,
options and design criteria listed shall constitute the City's comment to the
County on that aspect of the development application.
(2)
A "minor collector" is also known as a "residential collector", or a class "D"
street; and a "major collector" is also known as a "collector/industrial" or
class "C" street.
C.
Street Improvement Review and Requirements
1.
An applicant for a project or phase of a multi-phase project that is one
or more gross acres in size or which is forecast to generate one hundred
(100) or more average daily auto trips, shall complete and file with the
City Engineer as a part of the Development Review process a traffic impact
report. The report shall analyze the impact of the project or phase of a
project on the City, County and State road and street systems within one
(1) mile of the borders of the project or phase of a project, or to such
greater distance as necessary until the traffic analysis shows that the
impact of the project or phase of a project has dissipated to where it no
longer results in an impact of ten percent (10%) or more over current conditions.
Such report shall be prepared and certified by a registered traffic engineer.
The required report shall comply with the standards listed below:
a)
The report methodology shall generally be in accord with the standards
and procedures set forth in Washington County Resolution and Order 86-95
and related code provisions. The report shall distinguish between traffic
safety improvements found necessary due to the impacts of the project
or phase of a project, and roadway capacity improvements necessary because
of the traffic volume generated by the project or phase of a project.
The engineer shall include an estimate of the rough proportionality of
the identified safety improvements to the estimated impact of the project
or phase of a project, and may include a cost-effectiveness analysis for
all traffic safety problems and potential solutions identified by the
study.
b)
For development projects within a 2,600-foot radius of an LRT station
the applicant shall supplement the traffic impact report with a pedestrian
circulation study that:
i) indicates
the proposed routing and the various widths of all elements of the pedestrian
system;
ii)
identifies traffic calming measures which facilitate pedestrian movement
into and through the development project or phase of a project; and
iii)
uses the AASHTO or Highway Capacity Manual procedures, calculation methodology
and pedestrian level of service standards, including any such standard
specifically
applicable to light rail transit and related development.
c)
The general
performance standards for transportation facilities (as measured for both
intersection and roadway segments) shall be the Level of Service ("LOS")
measurements shown in Table 137.4. In determining LOS, the report shall
utilize the method prescribed in the latest edition of the Highway Capacity
Manual published by the Transportation Research Board.

(1)
Trigger point for capital improvement requirements.
(2)
A one-hour period measured during the peak hour between Noon and 2:00 p.m. (whichever
is higher) to assess off-peak congestion.
(3)
The one-hour peak period is measured at either the morning or evening peak period,
whichever is greater at the location of interest.
(4)
A LOS greater than indicated at a Critical Regional Intersection requires additional
intersection and arterial system analysis based on the methodology prescribed
in the Highway Capacity Manual, Special Report 1994, Chapter 11. The arterial
system analysis requires regional travel model (EMME-2) estimates of travel
speed for mid-block arterial sections and field study of "Time Travel Runs"
as specified in Chapter 11 of the Highway Capacity Manual.
(5) A 20 minute segment within the peak hour measurement where the maximum congestion
is reached, and not exceeded in any other 20 minute segment during the peak
hour.
(6)
Prior to accepting a "system" solution to an excessive LOS, the full cross-section
(all lanes) called for in the Comprehensive Transportation Plan's Functional
Classification Map shall be constructed.
(7)
It is not the intent to degrade the LOS of category 1 or 2 facilities as a result
of improvements on category 3 facilities. Installation of traffic signals at
category 1 or 2 intersections to achieve the LOS standard on category 3 facilities
shall only be allowed with the approval of the City /County/ State Engineer,
or designee, of the appropriate category 2/3 road authority.
2.
The City Engineer shall require appropriate safety, intersection and roadway
improvements within or adjacent to the project or phase of a project if
the traffic impact report required in paragraph 2 above indicates that:
a.
The project or phase of a project will cause unsafe conditions at site
accesses or on the roadways or at intersections within or adjacent to
the project or phase of a project; or
b.
The Acceptable Level of Service (LOS) Standard in Table 137.4 will be
exceeded for any impacted site access, intersection, or roadway within
or adjacent to the project; or
c. The
proposed off-street parking is insufficient and will cause excessive or
deleterious spill-over effect on the neighborhood or the adjacent road
or street system; or
d.
Traffic calming measures beyond those proposed by the applicant are warranted.
As
used in this subsection, "within" means interior to the entire project
proposed or available for current or ultimate development by the applicant
or under the applicant's control.
Notwithstanding
the definition contained in Section 136.III, "Adjacent" as used in this
subsection means any street, alley, bikeway, intersection, site access,
or pedestrian facility which borders on or abuts any portion of the project
that may in any way be impacted as a result of the subject project. "Adjacent"
as used herein also includes the nearest street and roadway intersections
in all directions from the proposed project that may be negatively impacted
by more than ten percent (10%) as a result of the project. (Amended
by Ord. No. 4545/4-97.)
3.
The City Engineer, during Development Review or at the appropriate phases
of the Concept Development Plan or Detailed Development Plan review process
(Section 136.VII.B), shall examine the proposed street, alley, sidewalk,
bikeway, and intersection improvements to determine: their adequacy to serve
the proposed use(s); consistency with applicable standards for roadway or
other construction requirements; compliance with adopted road standards;
and compliance with the provisions of Paragraph 1 of this subsection. When
necessary, the City Engineer may require the applicant to prepare a geotechnical
analysis and/or Pavement Design Report in order to determine whether the
proposed roadway structural design is sufficient to withstand the projected
traffic. The City Engineer shall require additional street, alley, sidewalk,
bikeway, and intersection construction and/or improvements beyond those
proposed by the applicant if necessary to meet any of these standards. (Amended
by Ord. No. 4545/4-97.)
4. In
addition to the requirements of paragraphs 3 and 4, if the results of the
traffic impact report required in paragraph 2, above, indicate:
a)
the project or phase of a project will contribute toward the need for
safety improvements at intersections or on the roadway system other than
within or adjacent to the project (known as the "off-site impact area"),
or
b)
The Level of Service Standard for any such impacted intersection or roadway
segment within the off-site impact area will be degraded to or below the
LOS shown in the "Not to Equal or Exceed" column of Table 137.4 as a result
of the project or phase of a project,
then,
the City Engineer shall require the applicant to construct, or contribute
a proportionate financial share towards construction of, any off-site capacity
and/or safety improvements necessary to eliminate the unsafe condition and
return the street/roadway segment and/or intersection to an "Acceptable
Level of Service." Similar off-site improvements identified by the traffic
impact report as affecting the County road and/or State highway system shall
be included in the calculations and made a part of the City's conditions
for project approval, upon written request by the County Engineer or ODOT
Region 1 Engineer, or their designee. (Added
by Ord. No. 4545/4-97.)
5.
The requirements for off-site improvements identified in paragraph 5 shall
be subject to the following provisions:
a)
The maximum required financial contribution from the applicant for necessary
off-site roadway capacity improvements shall not be required to exceed
the estimated amount of Traffic Impact Fees ("TIF") associated with the
project or phase of a project as calculated under the standard method
adopted by the City in Resolution No. 1596 pursuant to Washington County
Ordinance 379 as codified in Chapter 3.17 of the Washington County Code
as, or as may be, amended.
b)
The maximum required financial contribution, TIF Credits notwithstanding,
from the applicant for necessary off-site traffic safety improvements
shall not exceed an amount equal to the engineer's estimate of the proportional
share of the cost (1) of the identified safety improvement
based on the impact of the project or phase of a project as identified
in the Traffic Impact Report. However, if an applicant has not received
TIF credits equal to or greater than the amount of estimated Traffic Impact
Fees to be due before a Building Occupancy Permit is ready for issuance,
the applicant shall use the remainder of the credit to complete or contribute
towards completing the traffic safety improvements. At the request of
the City Engineer, an applicant eligible for TIF Credits shall implement
identified Traffic Safety improvements before applying credits toward
roadway capacity improvements.
c) If
the estimated amount of TIF fees available from the project or phase of
a project together with the required contribution for traffic safety improvements
is insufficient to complete the off-site traffic improvements within the
impact area, the City or the County or both may, but shall not be required
to, complete the off-site capacity improvements as revenues may become
available to their respective TIF Fund or other eligible transportation
fund.
(Added
by Ord. No. 4545/4-97.)
6.
If identified off-site improvements within the impact area are not completed
or guaranteed to be completed by the applicant, or by the City and/or the
County as provided above, or if there remains a traffic safety hazard, or
if the LOS is equal to or greater than shown in the "Not to Equal or Exceed"
column of the Table 137.4 on any street or roadway segment or intersection
within the impact area as a direct result of the project or phase of a project,
the Planning Director or the Planning Commission shall:
a)
deny the application, or
b)
approve the application in part, with a condition stipulating only the
portion or phase(s) of the proposed project which can be constructed without
exceeding the acceptable LOS standard and which does not cause a traffic
safety hazard may be built. In this event, an applicant may reapply for
subsequent portions or phases of the project when traffic and street conditions
have changed to the degree where the remainder of the project or phase
of a project can meet the safety and LOS standards cited above.
(Added
by Ord. No. 4545/4-97.)
7. Notwithstanding
paragraph 7, an applicant, on their own initiative, may offer either alone
or in consortium with others to complete and/or finance the completion of
identified off-site improvements beyond the limits described in paragraph
6 where such improvements mitigate identified traffic safety hazards or
achieve an acceptable level of service. Where such a proposal is made by
the applicant, the Planning Director or Planning Commission, as appropriate,
may approve the application provided the off-site improvements are guaranteed
by methods acceptable to the City Attorney and to the City Engineer and
are completed prior to any occupancy within the project or identified phase
of a project. (Added by Ord. No. 4545/4-97.)
8.
Where development occurs on previously undeveloped land containing 3.7 or
more gross acres, or where development is on a smaller parcel of land where
planned or existing streets and alleys are adjacent, streets and alleys
shall be laid out to create a grid system of through, connecting streets
and, where possible, shall connect or be planned to connect to existing
streets and roadways. The street system shall be reasonably straight and
direct, avoid unnecessary curving and exclude cul-de-sacs unless the street
terminates at a natural resources area or other obstacle where there is
little likelihood of future continuation. Where the development is in the
vicinity of a light rail transit station or a transit trunk route bus stop,
the streets shall be laid out to provide a direct and continuous route to
the transit stop or to such a roadway in an adjacent development. Block
perimeter lengths created by the street and alley pattern shall not exceed
1,600 feet.
9.
In Station Community residential and commercial districts, blocks created
in previously undeveloped areas shall incorporate, where practicable, an
alley system consistent with the proposed street grid and block perimeter
system to facilitate access to garages and accessory dwelling units located
near the rear of lots facing onto a public or private street, and to facilitate
utility and garbage service which might otherwise have to be accommodated
in or beside the public street at the front of the property.
__________________________
(1)
For purposes of this provision, the proportionate cost of a traffic
safety improvement attributable to the applicant shall equal the total cost
of the improvement times the ratio (percentage) of: the number of peak hour
trips through the intersection or roadway segment in question which are ascribe
to the project or phase of a multi-phase project, divided by the number of peak
hour trips at the same location before adding the impact of the project or project
phase.
D.
Alley Improvement Review and Requirements
1.
Development projects within the Downtown SCPA adjacent to any of the existing
or vacated alleys shown on Figure
5 shall dedicate the applicable portion of right-of-way as necessary
to complete a 20 foot ultimate right-of-way width. Alley right-of-way rededications
shall be required where alley right-of-way was previously vacated, upon
redevelopment of the property. Dedication or rededication shall be required
even if the alley right-of-way intersects with only one public street and
does not extend the full depth of the block. (Added by Ord. No. 4930/7-00.)
2.
In addition to dedication of alley right-of-way, development projects within
the D owntown SCPA adjacent to any of the existing or vacated alleys shown
on Figure
5 shall construct alley improvements sixteen (16) feet in width adjacent
to the property within the dedicated right-of-way where the full 20-foot
alley right-of-way width is available. Such alley improvements shall be
required even if the alley right-of-way intersects with only one public
street and does not extend the full depth of the block. Construction of
alley improvements shall be required whether or not the project proposes
to use the alley for access, unless construction is waived by the City Engineer
pursuant to Subsection 5. (Added by Ord. No. 4930/7-00.)
3.
In addition to the existing and vacated alleys shown on Figure
5, where the existing configuration of Tax Lots within a standard city
block (400 feet by 400 feet) has an identifiable east-west axis at mid-block,
alley right-of-way dedication shall be required on all lots abutting the
potential east-west alley, as necessary to establish a 20 foot ultimate
right-of-way width along the mid-block east-west axis. (Added by Ord. No.
4930/7-00.)
4.
Development projects within the Downtown SCPA adjacent to any newly dedicated
alleys created in compliance with Subsection 3 shall construct alley improvements
sixteen (16) feet in width adjacent to the property within the dedicated
right-of-way or perpetual easement, way, where the full 20 - foot alley
right-of-way is available. Such alley improvements shall be required even
if the alley right-of-way intersects with only one public street and does
not extend the full depth of the block. C onstruction of alley improvements
shall be required whether or the project proposes to use the alley for access,
unless construction is waived by the City Engineer pursuant to Subsection
5. (Added by Ord. No. 4930/7-00.)
5.
The City Engineer may waive alley construction requirements adjacent to
a development project if the subject site is an interior lot, without frontage
on a public street, upon determination that alley construction should be
deferred pending alley dedication and construction on intervening properties,
between the development site and the nearest public street. If alley construction
is deferred under these circumstances, the developer shall pay a fee in-lieu
of construction for the alley improvements.
6. In
conjunction with the alley improvements required in subsections 2. and 4.
above, the City Engineer may require an interim improvement, from the prope
r ty line to the nearest intersection with a public street. Such interim
improvement shall be constructed to accommodate emergency vehicle access
standards for weight and width, as approved by the City Engineer and the
Fire Marshal. (Added by Ord. No. 4930/7-00.)
7.
Alley dedication, construction, and use is the standard for development
in the Downtown SCPA outside the SCC-CBD. If a development pro posal is
eligible for alley dedication and construction under subsections 1 through
6 above, but does not include alleys, the developer must demonstrate why
alley construction is not feasible, and the development must comply with
all other applicable standards. Economic hardship is not considered proof
of unfeasibility. (Added by Ord. No. 4930/7-00.)
