ADMINISTRATIVE ORDER NO. 58-23-42
of the
City Engineer
City of Eugene, Oregon
AMENDING THE PUBLIC IMPROVEMENT DESIGN STANDARDS
MANUAL ADOPTED BY ADMINISTRATIVE ORDER NO. 58-16-01.
The City Engineer of the City of Eugene finds that:
A. Provisions in Chapters 6, 7 and 9 of the Eugene Code, 1971, impose requirements
and restrictions with respect to the design, location, and construction of public improvements.
Section 7.085 of the Code explicitly directs me, as City Engineer, to prepare design standards
and standard specifications for construction of public improvements.
B. Consistent with the above authority, on March 2, 2016, Administrative Order No.
58-16-01 was issued adopting an updated version of the Public Improvement Design Standards
Manual ("the PIDS Manual”).
C. The PIDS Manual adopted in 2016 included, as the standard for accessible
pedestrian facilities, the (then) 2011 Proposed Guidelines for Pedestrian Facilities in the Public
Right of Way as had been published by the Architectural and Transportation Barriers
Compliance Board (“U.S. Access Board”). On August 8, 2023, the U.S. Access Board issued its
final rule providing minimum guidelines for accessibility of pedestrian facilities in the public
right-of-way (36 CFR Part 1190) which became effective on October 7, 2023. In the absence of
legally required standards adopted by the US Department of Justice, the City Engineer continues
to consider those federal guidelines to be the best practices for new construction and alteration of
facilities within the public right of way to comply with accessibility requirements and is,
therefore, updating the PIDS Manual to reference the final “Accessibility Guidelines for
Pedestrian Facilities in the Public Right-of-Way” as published in 2023 at 36 CFR Part 1190.
Now, Therefore,
THE CITY ENGINEER OF THE CITY OF EUGENE ORDERS AND DIRECTS
THAT:
Section 1. The lead-in text of Section 2.02 of the PIDS Manual is revised as follows:
2.02 SHARED USE PATHS

Guidelines for Pedestrian Facilities in the Public Right-of-Way as published by the
United States Access Board (located on the internet at www.access-board.gov)
“Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way” as
published in 36 CFR Part 1190. All clear width measurements shall be exclusive of
the curb.
***
All new access ramps shall provide a minimum continuous clear width of 5 feet. A
clear width of 4 feet may be used in retrofit situations where existing infrastructure,
topography, or natural features warrant a reduced clear width. All new landings shall
provide a minimum 5-foot by 5-foot unobstructed area for turning space. A 4-foot by
4-foot landing may be used in retrofit situations where existing infrastructure,
topography, or natural features warrant a reduced area. Landings at corners or areas
with pedestrian signal push buttons shall be located to provide access to the push
buttons per the 2011 Proposed Guidelines for Pedestrian Facilities in the Public
Right-of-Way as published by the United States Access Board (located on the internet
at www.access-board.gov) “Accessibility Guidelines for Pedestrian Facilities in the
Public Right-of-Way” as published in 36 CFR Part 1190.
***
E. Locations
***
The design of the sidewalks shall ensure safe and accessible routes to bus stop
locations. The location of the bus stop shall be coordinated with the Lane Transit
district. Sidewalk design shall provide an accessible path of travel through the bus
stop locations. All bus stops shall be design in accordance with the 2011 Proposed
Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way as
published by the United States Access Board (located on the internet at www.access-
Administrative Order - Page 3 of 5
board.gov) “Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-
Way” as published in 36 CFR Part 1190.
***
Section 3. Section 2.05 of the PIDS Manual is revised as follows:
2.05 STREETS AND ACCESSWAYS

SECTION 1 - GENERAL REQUIREMENTS
1.00 INTRODUCTION
This manual contains the information needed to design public improvement projects for the
City of Eugene. Section 4 of this manual provides specific permitting details related to
privately-engineered public improvement (PEPI) projects.
1.01 DEFINITIONS
The following definitions are not intended to be a comprehensive list of terms associated with
the development of public improvements. Additional definitions may be found in the City
Code and the Standard Specifications and Drawings.
AASHTO: American Association of State Highway and Transportation Officials.
Access Ramp: The sloped area and landing immediately adjacent to the public way that allows
access to the public way by individuals with disabilities under the Americans with Disabilities
Act (ADA). Note: When the terms “access ramp” or “ramp” are used in this manual it shall be
understood to include the curb cut to the access ramp.
Agreement: Engineering and Construction Agreement between the City of Eugene and a
private entity defining the scope of work and that the public improvements shall be privately
engineered, constructed and financed.
City: The City of Eugene.
City’s project manager: City staff assigned to review and approve construction drawings for
the public improvements.
Code or City Code: The Eugene Code, 1971.
Contractor: Any individual or legal entity that has entered into a contract with the
owner/developer to construct the public improvements.
Critical root zone (CRZ): That area surrounding a tree that:
A. Has a radius of 18 inches times the diameter breast height expressed in inches of the
tree trunk or trunks; or
Public Improvement Design Standards Manual, 2023 Page 1-2
B. Encompasses an area determined for an individual tree to be the necessary root area
for the tree’s continued normal growth as demonstrated in a written report by a
certified arborist and based on documented field investigation and non-destructive
physical testing, including, but not limited to non-destructive excavation to delineate
the root system to a minimum depth of 24 inches below grade, and no more than 48
inches below grade.
Diameter breast height (dbh): The diameter of a tree trunk or trunks measured at 4.5 feet
above mean ground level at the base of the trunk or trunks.
Owner/Developer: Any individual or legal entity that has entered into an agreement with the
City for the purpose of constructing public improvements.
Plans: Construction drawings that show the location, type, dimensions, and details of the
work to be performed under the agreement.
Project: The work to be performed under the agreement.
Project Engineer: An Oregon Registered Professional Engineer (per ORS 672.002 to 672.325)
responsible for the engineering design of the public improvements.
Project Manager: An individual tasked with the initiation, planning, coordination, execution,
delivery and closeout of a project. The Project Manager serves as the primary point of contact
for all project related issues.
Shared Use Path: A paved, off-street travel way designed to serve non-motorized travelers
and maintenance vehicles.
Standard Specifications and Drawings (aka Standard Specifications and/or Standard
Drawings): The Oregon Standard Specifications for Construction Volumes 1 and 2, and the
Oregon Standard Drawings, both as revised by the City Amendments adopted by
memorandum of the City Engineer in effect.
Street Grades: Synonymous with curb grade, as the vertical profile of roadways is defined by
the top of curb alignment.
Work: The furnishing of labor, materials, equipment, and other incidentals required to survey
and design public improvements proposed for construction.
Public Improvement Design Standards Manual, 2023 Page 1-3
1.02 PURPOSE
The purpose of this manual is to satisfy the directive in Eugene Code 7.085 by providing design
standards for construction, reconstruction or repair of public improvements to be
constructed within areas under the City’s jurisdiction. This manual includes information for
the design, plan preparation, and related construction requirements for both publicly- and
privately-initiated work. To further facilitate consistency, the bulk of this manual is its
appendices, which consist of related resources and regulations. Naturally, these standards
neither address all situations nor absolve professional competency. As provided in Section
1.03, the City may approve systems not included in this manual for special conditions and/or
environmental constraints.
1.03 PROFESSIONAL ENGINEER LISCENSE REQUIRED - VERIFICATION
An Oregon Registered Professional Engineer shall place their seal on all documents in
accordance with ORS 672.020, OAR 820-010-0620, and OAR 820-010-0621. Licensed
professionals in other disciplines may apply their seal to documents in accordance with OAR
820-010-0623 provided the work is within their education, training, expertise and licensure
as defined by Oregon law. The seal of another professional in no way absolves the Project
Engineer’s responsibility to manage the project in its entirety.
In January of each year, the Computer Aided Drafting (CAD) leads for the City’s project
teams will check the Oregon State Board of Examiners for Engineering and Land Surveying
(OSBEELS) database to determine if the professional engineering licenses for the engineers
on their teams are active prior to the first time the engineer’s stamps are used. For those
licenses scheduled to expire in June, the CAD leads will check the OSBEELS database again
at the end of July to determine whether those mid-year licenses have been renewed and
continue to be active. If licenses are found to be inactive, the CAD leads will immediately
notify the engineers whose license are inactive and the principal engineers. Expiration
dates for the stamps will not be updated in CAD until the OSBEELS database has been
checked to confirm the licenses are active. At no time will expired stamps be placed on
review plans, final plans or as-built sheets.
The City’s PEPI Manager or designee shall check OSBEELS database to determine if the
professional engineering licensees for engineers on PEPI projects are active prior to PEPI
plan approval. PEPI plans must be approved with the seal of an active Professional
Engineer.
1.04 DESIGN EXCEPTIONS AND DEVIATIONS
These standards are not intended to limit innovation or creativity, particularly when such
efforts result in higher quality and/or lower costs. Departure from the required standards
Public Improvement Design Standards Manual, 2023 Page 1-4
shall be determined by the City, as well as the Oregon Department of Transportation (ODOT)
where ODOT right-of-way is involved and the Federal Highway Administration (FHWA) where
federal funding is involved, per the criteria listed below.
A non-standard system may take longer to review, resulting in increased processing costs
incurred by the applicant. This information shall be conveyed to an applicant, who, by filing
an application for a non-standard system for review, acknowledges and agrees to pay the
potentially increased processing costs.
Deviations from any standard in this manual require approval by the City Engineer prior to
completion and approval of plans and specifications. To obtain approval, the designer must
submit a completed “City of Eugene Design Exception Request” form with a cover memo,
which shall include a description of the problem, its proposed solution, and any other
information to justify the exception. When ODOT approval is required, use the “City of
Eugene’s Oregon Department of Transportation Design Exception Request” form.
The City’s decision to grant, deny, or modify the proposed deviation shall be based upon
evidence that the deviation request meets all of the following criteria:
a. The change will achieve the intended result through a comparable or
superior design.
b. The change will not adversely affect safety and/or operation.
c. The change will not adversely affect maintainability.
1.05 DESIGN CALCULATIONS
All design calculations and studies for pavement structures, flood control, water quality, and
wastewater systems shall be submitted in an organized, legible, and professional form for
review. These calculations, bearing the signature and stamp of the Project Engineer, shall also
include a thorough list of assumptions used in making the calculations. Any material of
unacceptable quality and accuracy will be returned to the applicant for correction and
resubmission.
1.06 ERRORS AND OMISSIONS
Any errors or omissions in the approved plans or information used as a basis for the approval
may constitute grounds for approval withdrawal and/or stoppage of any or all of the
permitted work, as determined by the City. It shall be the responsibility of the
Owner/Developer and assigned agents to demonstrate why such work should continue, and
to make changes to the plans as may be required by the City before approval of the plans is
reinstated.
Public Improvement Design Standards Manual, 2023 Page 1-5
1.07 CONSTRUCTION STANDARDS
All design and construction of public improvements shall comply with the current edition of
the City’s Standard Specifications and Drawings. To obtain the current Standard Specifications

Public Improvement Design Standards Manual, 2023 Page 2-1
SECTION 2 – DESIGN STANDARDS
2.00 INTRODUCTION
This section provides design standards for public improvements (e.g., transportation,
wastewater, and stormwater systems), although it does not supersede or account for all
applicable local, state, and federal regulations, which are referenced and provided in the
appendices to the greatest extent practicable.
2.01 GENERAL
A. Construction Site Management
A Construction Site Management Plan (CSMP) is required for all public improvement
projects and shall be included with the set of public improvement project plans submitted
to the City for approval. The CSMP should describe both long- and short-term methods
for preventing a construction activity’s impacts to water quality and on-site and adjacent
natural resources. The CSMP is a protection plan intended to illustrate measures for
shielding and covering specific site features, rather than a construction plan; the CSMP
does not authorize construction or impacts to waterways, trees, and other site features.
See Appendix A for required CSMP Notes and Plan Requirements.
B. Erosion Prevention
An Erosion Prevention Permit is required for all project areas that: (1) disturb one or more
acres; or, (2) disturb 500 square feet or more of land and is located in a “sensitive area”
as defined by the City Code. See Erosion Prevention and Construction Site Management
Practices Administrative Rule R-6.645” attached as Appendix A.
C. Floodplain Development
A Floodplain Development Permit is required prior to any development occurring within
the Special Flood Hazard Area (SFHA). The SFHA includes Zones A, AE, AO and the
Floodway for our community on the adopted Flood Insurance Rate Map (FIRM). The FIRM
was created by the Federal Emergency Management Agency (FEMA) as part of the
National Flood Insurance Program. Development includes any man-made-change (e.g.,
building, filling, excavating, grading, paving, etc.) within the regulatory floodplain.
Floodplain Development Permits can be obtained at the Permit and Information Center.
Public Improvement Design Standards Manual, 2023 Page 2-2
See Appendix B for permit requirements. Special Flood Hazard Areas must be delineated
on the CSMP as noted in Section 3.
D. Geological and Geotechnical Analysis
A geological and geotechnical analysis is required for the construction of a public street
or alley or the construction of public drainage systems or public wastewater sewers. For
investigation methods and required report content, see “Standards for Geological and
Geotechnical Analysis Administrative Rule R-9.6710” attached as Appendix C.
E. Property Owner Notification
The Project Engineer must notify private property owners and obtain Permit of Entry
letters from those private property owners whenever construction activities are
necessary on private properties outside of the public right-of-way.
While Eugene Code 7.350 permits property owners served, or to be served by a utility
within a public utility easement, access to the public utility easement to construct, install,
maintain, and repair private utility services, the City will not approve construction
activities impacting private property or a property owner’s use of their property without
proper notification. Persons needing to work on property owned by someone other than
the developer must give the affected property owner notice of their intent and submit
proof of the notification to the City. The notice shall include a description of the work to
be completed, when the work will be done, how long the activity is expected to occur,
and that the site will be restored to its current condition.
A Permit of Entry letter signed by the affected private property owner acknowledges that
the private property owner has received the notice of intent for construction activities on
their property and they acquiesce to entry for construction. A Permit of Entry letter is also
required to construct a driveway adjustment outside the right-of-way between a new or
reconstructed sidewalk or street section and an existing driveway.
F. Public Infrastructure Placement (Right-of-Way / Easements)
Public infrastructure must be located in right-of-way or public easements; the appropriate
dedication instrument will be determined by the City. In most cases, right-of-way is
preferred over easements; the latter may require additional documentation with the
affected property owner to further clarify operation rights and maintenance
responsibilities.
Public Improvement Design Standards Manual, 2023 Page 2-3
G. Street Cutting Prohibitions
Excavations shall not be permitted when the pavement is less than five years old unless a
street cut prohibition exception has been granted in accordance with the provisions of
Eugene Code 7.295(2) and the “Utility and Right-of-Way Permits, Construction Within and
use of the Public Way” Manual. To obtain the current Utility Manual, contact Public Works
maintenance, 541-682-4800 or the online Public Works Maintenance webpage at:
www.eugene-or.gov. ”
H. Tree Regulations
Trees are identified as either “street trees” or “non-street trees.” Trees are primarily
regulated under Chapter 6 and 7 of the Eugene Code. Provisions regarding street trees
are administered by the Parks and Open Space Urban Forestry Program. Contact Public
Works Maintenance, 541-682-4800 or the online Public Works Maintenance webpage at:
www.eugene-or.gov. Non-street trees are administered by the Land Use Tree Program.
Contact Planning and Development, 541-682-5086 or the online Planning and
Development webpage at: www.eugene-or.gov. If non-street trees are to be removed as
part of land use development, Chapter 9 provisions also apply. Impacts of public
improvement projects on trees will be evaluated according to both Chapters 6 and 7 of
the City Code. See Appendix D for more information on applicable regulations. Tree
protection must be delineated on the CSMP as noted in Section 3.07.
2.02 SHARED USE PATHS
Shared use paths shall be designed in accordance with the City’s Design Standards and
Guidelines for Streets, Sidewalks, Bikeways, and Accessways (provided in Appendix E and on
the internet at www.eugene-or.gov), the Standard Specifications and Drawings, and the
“Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way” as published in
36 CFR Part 1190. Shared use paths shall also be designed to comply with the following:
A. Bollards
Bollards are intended to restrict unauthorized use of the off-street path system by motor
vehicles or to prevent access to load restricted structures by motor vehicles. The location
of and determination to install bollards is subject to City approval. Bollard installations
shall not restrict access to people with disabilities and be easily visible, especially in low
light and poor weather conditions. When installed, bollards shall provide a minimum 4-
foot opening and maximum 5-foot and 6-inch opening. Where multiple bollards are
Public Improvement Design Standards Manual, 2023 Page 2-4
installed, spacing shall be such that when the center bollard is removed, a 10-foot
maintenance or emergency vehicle access width is available. When multiple bollards are
used, a central bollard shall always be placed on the centerline of the facility. Bollards
shall comply with the Manual on Uniform Traffic Control Devices (MUTCD) guidelines and
conform to City Standard Drawing TM820(B) for removable bollards.
B. Clearance
The minimum vertical clearance from obstructions (structures, signs, trees, etc.) above
shared use paths is 9 feet.
C. Cross-Slope
The cross-slope for shared use paths shall not exceed 2 percent.
D. Grade
Longitudinal slope of shared use Paths shall not exceed 5 percent. Where compliance is
not practical due to existing topography, infrastructure, right-of-way availability, a
notable natural feature, or similar existing physical constraints, the Project Engineer may
submit an application for a deviation.
Grade breaks may be used when the grade change at a station is 2 percent or less, except
grade breaks at driveways and access ramps shall meet the design standards for those
facilities. For paths less than 8 feet wide, grade breaks may be up to 5 percent.
E. Intersections
All shared use path intersections shall be designed to accommodate the maintenance
vehicle (type and dimensions to be provided by the City) for all turning movements within
the paved surface. The minimum radius for any corner shall be 15 feet. The shall provide
documentation demonstrating the design vehicle can navigate all turns within the paved
surface using vehicle turning movement modeling software (i.e., Auto-turn or equivalent).
F. Lighting
All new shared use paths shall include LED lighting. The design shall include a lighting
analysis based on an average maintained illuminance level between 0.7 and 1.0
footcandles. The Design Engineer may also layout the luminaries in accordance with the
spacing table provided below. The design shall comply with the Design Standards for
Street Lighting Systems located in Appendix G, the Standard Specifications and Drawings,
and the applicable lighting requirements provided in Section 2.05.

10-12 Feet 25 Feet Type 1 4600 130 Feet
Additional Requirements for path lighting:
• Control the use of light by using only enough light to ensure safety for path users
and by minimizing illumination of areas outside the path.
• In natural areas, use an International Dark-Sky Association approved fixture
featuring long wavelength light with a red or yellow tint to minimize impact to
wildlife.
G. Markings and Signage
Markings and signage may also be required to address safety issues on shared use paths
or to aid in the navigation of the bicycle and pedestrian network.
H. Pavement
All paths shall be surfaced with Portland Cement Concrete (PCC). PCC pavement
structures shall be designed using either the AASHTO-approved rigid pavement or
Portland Cement Association (PCA) approved design specifications. Pavement design for
shared use paths shall factor in the Contractor’s use of the subgrade, base and pavement
structure during construction and/or the use of the path by maintenance equipment and
emergency vehicles following completion of construction. The pavement design shall
consider the use of the path subgrade and base by construction vehicles and equipment
and, as needed due to soil conditions or other factors; include design and construction of
an aggregate base working platform in order to avoid subgrade damage or failure. Prior
to beginning the design analysis the designer shall consult with the City to identify the
appropriate post-construction vehicles (e.g., City, utility company, emergency vehicles
etc.). A narrative discussion of how the vehicle(s) were accommodated in the design must
be included in the analysis report.
Public Improvement Design Standards Manual, 2023 Page 2-6
The minimum 28-day compressive strength for PCC shall be 3300 psi for shared use paths.
No vehicles, including construction equipment, shall be permitted to use the pavement
until it has reached its full design strength. No exception will be given to allow use of PCC
shared use paths prior to reaching design strength.
The minimum pavement thickness shall be determined by the pavement design analysis
but in no case shall be less than 7 inches.
All joints within shared use paths shall be saw cut. Transverse contraction joints shall be
spaced at relatively equal spacing between joints and shall be close to the same spacing
as the longitudinal joints so that the panels are relatively square. Spacing between
transverse joints shall not exceed 15 feet for PCC that is 7 inches or more in thickness.
The length to width ratio for any panel shall be at least 0.75 and shall not exceed 1.25.
Joint reinforcement is not required for shared use paths except as required by the
pavement design.
The minimum aggregate base thickness shall be determined by the pavement design
analyses but not less than 2 inches of compacted 3/4 inch-minus crushed rock shall be
placed before the concrete pavement is poured.
(See Appendix E for Shared use Path Standard Detail)
2.03 SIDEWALKS
Sidewalks shall provide an unobstructed, continuous and safe path for pedestrians and be
designed in accordance with the City’s Design Standards and Guidelines for Streets, Sidewalks,
Bikeways, and Accessways (provided in Appendix E and on the internet at www.eugene-
or.gov), ADA requirements, the Standard Specifications and Drawings, and the following:
A. Access Ramps
Each access ramp and its associated wings, landing and other appurtenances shall be
included in the plans and shall comply with the “Accessibility Guidelines for Pedestrian
Facilities in the Public Right-of-Way” as published in 36 CFR Part 1190. All clear width
measurements shall be exclusive of the curb.
At new intersections, access ramps shall be constructed in the projection of all crosswalks
as defined by the Oregon Vehicle Code. Receiving ramps shall be constructed on the
opposing side of newly established intersections. A design exception, per Section 1.04,
may be authorized in retrofit situation where a crossing is impractical due to
Public Improvement Design Standards Manual, 2023 Page 2-7
topographical or utility challenges. A design exception may also be authorized in a retrofit
situation where an engineering study indicates a crossing is not warranted.
Perpendicular and parallel ramps are allowed as defined by the Proposed Accessibility
Guidelines. Perpendicular ramps are preferred and shall be used where conditions allow.
Parallel ramps may be used in the presence of curb tight sidewalk or in locations where a
perpendicular ramp is impractical due to topographical, right-of-way or utility challenges.
All new access ramps shall provide a minimum continuous clear width of 5 feet. A clear
width of 4 feet may be used in retrofit situations where existing infrastructure,
topography, or natural features warrant a reduced clear width. All new landings shall
provide a minimum 5-foot by 5-foot unobstructed area for turning space. A 4-foot by 4-
foot landing may be used in retrofit situations where existing infrastructure, topography,
or natural features warrant a reduced area. Landings at corners or areas with pedestrian
signal push buttons shall be located to provide access to the push buttons per the
“Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way” as
published in 36 CFR Part 1190.
The design of ramps shall utilize winged (flared) returns to the maximum extent practical.
The use of curbed returns shall be used in areas of right-of-way limitations or
circumstances where vertical curbing is appropriate due to grading or infrastructure
conflicts. In no case shall stand-alone linear curb be utilized. Underexposing wings is
acceptable in retrofit situations in order to maintain maximum wing slope.
Grade breaks shall be perpendicular to the path of travel. The remaining triangle shaped
area between the truncated domes and the gutter line shall be graded to a maximum 5%
counter slope provided it is not part of the turning space or landing.
Access ramps shall be designed for directional orientation of the user. The centerline of
each ramp shall be oriented to line up and coincide with the centerline of the ramp on
the opposite side of the street as closely as practicable. The Design Engineer shall prepare
design detail drawings for each corner with ramps, each mid-block crossing, and every
other ramp location shall be included in the plans at no greater than a 1 inch = 5 feet
scale. Each drawing shall include complete design information such that the
improvements may be constructed without further design calculation by the Surveyor,
Inspector or Contractor.
Access ramp drawings shall include dimensions for all features of the new improvements,
including but not limited to:
Public Improvement Design Standards Manual, 2023 Page 2-8
1. Lengths and widths between all elevation points along grade breaks and sides of all
curb and gutter, ramps, wings, landings and associated concrete walk;
2. Lengths and widths of all sides of the ramps, truncated dome surfacing, landings, and
sidewalk leading into the landings, and lengths of curb and gutter that are not
included in the first bullet; and
3. All other lengths and widths of associated concrete walk improvements needed to
complete the Access ramps as shown on the special detail plans.
Access ramp drawings shall also include design elevations for all features of the new
improvements, including but not limited to:
1. Elevations for the flow line of the gutter and the top of curb:
a. Where each side (when extended past the depressed curb) of the ramps intersect
the gutter;
b. At break points for the wings;
c. At grade break points in the curb and gutter;
d. At match points to existing curb, and at other points as needed for a complete
design.
2. Elevations in the ramps, wings and landings:
a. At all grade break points;
b. At all match points to existing walk, and at other points as needed for a complete
design.
Also see Section 2.05 Intersection standards.
B. Clearance
The minimum vertical clearance from obstructions above sidewalks is as follows:
• 7 feet from the bottom of a sign
• 8 feet from building overhangs
• 7 feet from awnings
• 9 feet from overhanging vegetation, such as tree limbs
C. Grading Type
The standard grading type for sidewalks is setback; alternate designs are subject to the
standards noted below. (See Appendix E for Typical Grading Sections Standard Detail)
Public Improvement Design Standards Manual, 2023 Page 2-9
Sidewalks adjacent to roadside stormwater facilities shall be designed to accommodate
specified maximum facility slopes per the Stormwater Management Manual.
Stormwater quality facilities without a barrier curb shall be separated from the sidewalk
with a 12-inch shoulder graded at 2% or less.
D. Lighting
See Section 2.05 for applicable lighting requirements.
E. Locations
When an exception has been approved allowing sidewalks on only one side of the street,
the sidewalks shall be located within the development on the side of the street where
on-street parking is permitted. In cases where a single sidewalk is allowed due to physical
constraints, such as wetlands or trees, the sidewalk shall be located on the side opposite
from the constraints.
The design of the sidewalks shall ensure safe and accessible routes to bus stop locations.
The location of the bus stop shall be coordinated with the Lane Transit district. Sidewalk
design shall provide an accessible path of travel through the bus stop locations. All bus
stops shall be design in accordance with the “Accessibility Guidelines for Pedestrian
Facilities in the Public Right-of-Way” as published in 36 CFR Part 1190.
F. Sidewalk Bicycle Parking
Short term bicycle parking should be placed on the sidewalks where a minimum clear
distance of 8 feet is provided between the bicycle rack and the back of sidewalk. The
inverted “U” rack shall be used for all on street bike parking. Racks installed on the
sidewalk or furnishing zone shall be a minimum of the 2 feet from the face of curb.
Inverted “U” racks shall be placed a minimum of 4 feet apart when placed horizontally
along the curb. Racks installed on the sidewalks shall be a maximum of 50 feet from main
building entrances and be highly visible from adjacent bicycle routes and pedestrian
traffic.
Public Improvement Design Standards Manual, 2023 Page 2-10
2.04 STORMWATER
Stormwater management facilities required under provisions of Chapter 9 shall be designed
in accordance with the Stormwater Management Manual, City’s Stormwater Basin Master
Plans, Standard Specifications and Drawings, Eugene Code Chapters 6 and 7, and the
following standards.
A. Analysis (Stormwater Study)
A stormwater study shall be submitted for all stormwater systems that carry runoff from
more than one acre of land. The study shall include all of the following elements.
1. A hydrology map containing the following:
a. The entire drainage basin boundary and 100 feet of area beyond the drainage
basin limits.
b. All sub-basins shall be delineated with symbols that are labeled and readable
when electronically scanned.
c. Drainage areas of all sub-basins (in acres).
d. Streets important to the study and street names.
e. Flow path or direction arrows in streets, pipes, streams, and ditches.
f. Contours or spot elevations for verification of direction of overland flow and
pipe cover.
g. Collection points (nodes) at downstream limits of all sub-basins, with node
numbers.
h. Existing and proposed storm drain pipes with material type and sizes included.
i. Future pipes in the system, complete with proposed sizes, slopes, pipe cover,
flow line elevations at manholes.
j. City drainage master plan information such as node numbers, basin names,
and drainage boundaries.
k. Existing and proposed surface water features and drainage systems, including
but not limited to: streams, wetlands, drainage channels, and stormwater
conveyance/treatment systems.
l. Legend details such as north arrow, scale, company name/logo, designer, and
date.
2. Hydrologic calculations to establish runoff flow amounts.
3. Hydraulic calculations to establish pipe size, waterway cross-section, flow
velocity, and hydraulic grade line (HGL).
Public Improvement Design Standards Manual, 2023 Page 2-11
4. The report shall include related charts, graphs, calculations, summary tables and
supporting narrative.
B. Basin Boundaries
Stormwater systems shall be designed to convey the calculated runoff from the entire
upstream drainage area during the applicable design storm event (See Appendix J). Basin
boundaries shall be consistent with the City’s Stormwater Basin Master Plan, unless
otherwise approved by the City based on more current data. Runoff calculations shall be
based on the assumption of a full-build-out basin according to the land use designations
of the most recent Metropolitan Plan.
C. Hydraulic Grade Line (HGL)
The hydraulic grade line at the outfall (downstream discharge point of the drainage area)
shall be based on the most current water surface elevation information identified in the
City’s Stormwater Basin Master Plan or other data as approved. Hydraulic analysis shall
account for energy losses (bend losses, manhole losses, other "minor" losses, friction
losses, etc.) and differences in flow characteristics between surcharged systems and open
channel systems. Minor losses shall be computed using formulas in the Oregon
Department of Transportation hydraulics manual.
Stormwater systems shall include a hydraulic analysis of all existing pipes and waterways
downstream to the point of outfall. The water surface elevation from the City’s
Stormwater Basin Master Plan or a previously-approved storm study may be used as a
starting point for the design. If the ultimate plan is for future construction of pipe between
an existing pipe downstream and the current project, and if the current condition through
this reach is an interim system, the design water surface elevation shall be based on the
hydraulics of the future pipe rather than on the interim system, and shall be labeled
"future HGL".
The HGL for the design storm event shall not be less than 6 inches below the gutter at any
point where water could surcharge into the street (catch basins, manholes, curb inlets).
If the hydraulic analysis of an existing downstream system is not available through the
City’s Stormwater Basin Master Plan, the engineer may choose to extend the XP-SWMM
model using methods and assumptions consistent with the City’s modeling work to
determine the starting HGL for the system.
Public Improvement Design Standards Manual, 2023 Page 2-12
D. Manholes
1. Pipe Grades and Channel Slope
Manholes shall be designed to minimize head loss through the structure. The crown
of the pipes exiting the manhole shall not be higher than the lowest crown of the pipes
entering the manhole, or, 80 percent of the flow depth of the pipe exiting the manhole
shall not be higher than the lowest flow depth of the pipes entering the manhole.
The slope of the channel through a manhole shall be the same as the pipe upstream
from the manhole; any change of pipe grade shall occur at the manhole outlet.
2. Locations
Manholes shall be installed at each of the following locations:
• End of each main line
• Changes in grade, size or alignment (vertical and horizontal)
• Distances not greater than 400 feet for pipes 24 inches and smaller
Manhole spacing for pipes 30 inches and larger shall be as directed by the City to meet
operational considerations at each location. In no case shall the manhole spacing
exceed 800 feet for pipes 30 inches and larger.
Blind connections are allowed for catch basins, area drains and curb inlets where
structures serve roadway drainage and are located at right angles to the storm mains
in the roadway.
Manholes shall be positioned outside normal wheel travel paths (centered in the lane
or between lanes) and outside the center of an intersection where the turning path
of vehicles may place a wheel path over them.
3. Shallow/Flat Top Manhole
A shallow or flat top manhole shall be used when there is less than 5 feet of cover
over a pipe.
4. Size and Diameter
See City Standard Specification for Construction and Standard Drawings for manhole
style, size and material properties.
Public Improvement Design Standards Manual, 2023 Page 2-13
E. Off-Site Flows
Closed or piped drainage systems from lands outside the development site and having
flows through the new stormwater systems shall be "public" systems and constructed to
one or more of the development boundaries. The system shall be sized and located to
accommodate all pre and post development contributing off-site flows in accordance with
the City’s Stormwater Master Plan. Guidelines for the extension of the public stormwater
system can be found in the City’s Stormwater Master Plans.
Construction of public roadways or other improvements that alter historic drainage
patterns shall include the constriction of conveyance facilities to accommodate historic
drainage patterns.
F. Pipes
Pipes shall comply with the following:
1. Cover
A minimum 4 feet of cover shall be provided over the top of the pipe from expected
finish grade. Where pipe cover is proposed to be less than 4 feet or more than 10 feet,
the Design Engineer shall provide documentation and/or design calculations to show
that the pipe is structurally adequate to withstand construction loadings and traffic
loading.
Notwithstanding the above guidance, a CLSM cap shall be required where the top pipe
is within 2 feet of finished grade.
2. Diameter
The minimum pipe diameter shall be 10 inches for all stormwater drainage pipes.
3. Curves, Horizontal and Vertical
Horizontal and vertical curves are not permitted except in steep terrain, and then
only:
a. One horizontal curve is permitted between any 2 manholes provided there
is no vertical curve in that section; or,
b. A maximum of 2 vertical curves is permitted between any 2 manholes.
c. Joint deflection shall be no greater than pipe manufactures’
recommendations.
Public Improvement Design Standards Manual, 2023 Page 2-14
4. Flow Depth
Target for depth of flow in pipes during the flood control design storm shall be 80% of
pipe diameter. A particular design may result in a deeper or shallower flow, but pipes
shall not be designed to flow surcharged unless outfall conditions or other hydraulic
conditions prevent open channel flow.
5. Manning’s Roughness Coefficient (“n” value)
“n” value for PVC pipe shall be 0.010
“n” value for concrete pipe shall be 0.013
“n” value for metal pipe shall be 0.020
6. Materials
Stormwater pipe may be concrete, ductile iron, PVC or metal. See Appendix I for the
Metal Pipe Design Policy.
7. Skewed Pipe Systems
Pipe networks in streets shall be designed parallel to street centerlines whenever
possible; skewed pipe alignments are discouraged.
8. Velocity
Minimum velocity permitted for design flow is 3 feet-per-second (fps). When design
Q causes a pipe to flow surcharged at less than 3 fps, the engineer shall demonstrate
that flow in the pipe will exceed 3 fps during normal low-flow, non-surcharged
conditions.
9. Buoyant Forces
The effect of buoyant forces shall be checked for all pipes and manholes used below
the normal water table. Buoyant forces shall not be greater than the weight of the
pipe, manholes and backfill.
G. Underground Injection Control (UIC) Facilities
New public UIC facilities are prohibited. All existing public drywells are scheduled for
decommissioning. Existing drywells were installed as a temporary solution to
stormwater management. No additional flows shall be directed to existing drywells.
Construction of stormwater conveyance systems in the vicinity of existing drywells
Public Improvement Design Standards Manual, 2023 Page 2-15
shall include facilities and capacity to accommodate the removal of the drywells.
H. Service Laterals
The street gutter is the primary stormwater collection and conveyance system for
individual lot drainage. Lot drainage shall be served by weepholes in the curb where
possible. No new bubbler systems shall be allowed. Bubbler systems may be
approved, at the discretion of the City Engineer, where weepholes or piped
conveyance are unavailable or unfeasible.
Stormwater service laterals shall be allowed where drainage from private lots
cannot be accommodated by weepholes in the curb. Stormwater laterals are
allowed where stormwater conveyance requires a pipe diameter of 8 inches in
diameter or greater to convey the flood control design storm. Laterals may be
connected to the mainline or existing drainage structures (curb inlets and catch
basins) provided the Project Engineer demonstrates conveyance capacity through
hydraulic analysis.
Manholes are required where stormwater laterals connect to the mainline. A blind
connection may be used where the diameter of the mainline is twice the diameter of
the lateral or greater. Blind connections shall be perpendicular to the main line.
Catch basin or curb inlets may serve as points of connection.
Stormwater laterals may be allowed, at the discretion of the City Engineer, for single
family dwellings that cannot be served by weepholes. Laterals may be approved
where protection of property and drainage of standing water warrants piped
conveyance.
2.05 STREETS AND ACCESSWAYS
Streets and accessways are required to comply with the City’s Design Standards and
Guidelines for Eugene Streets, Sidewalks, Bikeways, and Accessways (available in Appendix E
and on the internet at www.eugene-or.gov.). The information below provides greater detail
regarding the standards for construction design review. The following are links to other
transportation publications referenced below:
• American Association of State Highway and Transportation Officials (AASHTO)
publications are available at https://bookstore.transportation.org.
• The Federal Highway Administration (FHWA) Manual on Uniform Traffic Control
Devices (MUTCD) is available at http://mutcd.fhwa.dot.gov.
Public Improvement Design Standards Manual, 2023 Page 2-16
• Oregon Department of Transportation (ODOT) publications are available at
www.oregon.gov/ODOT/HWY.
• The “Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way” as
published in 36 CFR Part 1190 are available at https://www.ecfr.gov/current/title-
36/chapter-XI/part-1190.
A. Access Management / Access Connections
Access connection location and width is regulated by Eugene’s codified access
management standards (see Eugene Code Chapters 7 and 9). Additional requirements
regarding driveway construction are provided below (see Standard Drawings for details).
1. Aprons for Driveways
Aprons shall extend from the gutter to the back of the concrete walk; if no walk exists,
the apron shall be 5 feet deep, measured from the back of the curb (5 feet and 6
inches from gutter). Aprons shall comply with accessibility requirements in the area
of the sidewalk unless no sidewalk is present adjacent to the proposed apron and no
sidewalk is to be built connecting to the apron at the time of development and the
City determines no sidewalk will be built connecting to the apron in the future.
2. Driveway Adjustments
Because grades of existing driveways usually do not match the grade of a newly
constructed street, a portion of the existing driveway must often be removed and
rebuilt to match the new street. In doing so, the following basic design criteria must
be included:
a) Driveway grades for driveway adjustments shall be designed as provided in the
Standard Drawings.
b) Natural drainage (overland surface flows) shall not be impeded (no ponding).
See the Standard Specifications and Drawings for details.
Permission should be obtained from the adjacent property owner prior to any work
outside public right-of-way or easements.
B. Bridges
Design standards for bridge projects in the City of Eugene shall be in compliance with the
Public Improvement Design Standards Manual, 2023 Page 2-17
standards specified in AASHTO’s Bridge Design Specifications and Guide Specifications for
Highway Bridges with related references, as well as the following ODOT manuals: Bridge
Design and Drafting Manual; Geotechnical Design Manual; and Hydraulics Manual. The
City of Eugene will contract plan review and inspections to a qualified independent
engineering firm. The additional cost of plan review and inspection shall be borne by the
applicant.
C. Bus Routes
Pavement testing and pavement rehabilitation/strengthening as necessary is required to
accommodate new bus routes on a street and/or changes in bus usage of a street prior
to the implementation of the new route(s) or change in bus usage. Examples of change in
usage and/or new routes include, but are not limited to: adding a new bus route or
changing an existing bus route to use streets not previously used for bus routes or not
used in the past 5 years for bus routes; removing parking and shifting traffic to allow a
bus only lane in the curbside lane or center lane; or, changing a low volume curbside right
turn lane into a lane that allows through and right turn traffic in which buses then shift to
using the curbside lane.
Prior to a change in usage and/or adding a new route as described above, complete
pavement testing and rehabilitation/strengthening design of the existing pavement in
accordance with the requirements of Section 2.05 R.1. and 2. for AC pavement and 2.05
R.3 for PCC pavement to determine if strengthening or reconstruction of the street is
needed to accommodate the route change/addition. If strengthening or reconstruction
of the existing pavement is recommended by the pavement design, complete the
strengthening or reconstruction prior to the route change or addition.
In addition to the requirements above, lanes planned for usage as bus rapid transit routes
shall be paved with PCC with a 50-year design life prior to establishing a route on the
street. The PCC lanes shall also extend through all intersections crossed by the route. All
bus rapid transit stops located in public rights of way shall be paved with PCC with a 50-
year design life.
D. Centerline
1. Crown
Streets shall be designed with a 2 percent straight grade from centerline to gutter except
when matching existing parabolic streets. The crown on streets extended either laterally
or longitudinally shall be the same as that on the existing street.
Public Improvement Design Standards Manual, 2023 Page 2-18
2. Location
The centerline of a proposed street shall be positioned on the center of the pavement
width.
3. Radii
For all local residential streets, the minimum centerline radius is 100 feet. This standard
is set to keep the design speed consistent, as well as to provide safety. Exceptions may be
allowed for access lanes and low volume streets in the following situations:
1. To facilitate traffic calming,
2. To connect the proposed street to other developments,
3. To protect natural resources,
4. When there are no alternate property configuration designs available (long or
odd-shaped parcels) which would maximize development area by increasing lot
frontage or achieving density goals.
For a centerline radius shorter than 100 feet, traffic calming features such as signing,
striping, and traffic markers may be required. Parking on curves with less than 100-foot
centerline radius is prohibited.
E. Crosswalks
Crosswalk markings indicate to pedestrians the appropriate routes across traffic,
facilitate crossing by the visually impaired, and remind drivers of potential conflicts
with pedestrians. Locating crosswalks shall be as follows (see Section 2.07 Traffic
Control Devices and Standard Drawings for marking details):
1. Crosswalks at signalized intersections shall be marked.
2. Crosswalks at un-signalized intersections may be marked under the following
conditions:
a. At complex intersections to orient pedestrians.
b. At offset intersections to show pedestrians the shortest route across traffic
with the least exposure to vehicular traffic and traffic conflicts.
c. At intersections with visibility constraints to position pedestrians where they
can best be seen by on-coming traffic.
d. At pedestrian crossing islands.
3. Crosswalks on designated school routes shall be the “Continental” type. In
Public Improvement Design Standards Manual, 2023 Page 2-19
addition to providing “Continental” markings, “Rectangular Rapid Flashing
Beacons” may be required to increase the visibility of and call attention to the
crossing.
4. Mid-block crossings shall be marked crosswalks. Mid-block crossing shall be
marked with “continental” style markings where pedestrian refuge islands are
present. In addition to providing crosswalk markings, “Continental” style markings
and/or “Rectangular Rapid Flashing Beacons” and/or hybrid pedestrian signals
may be required to increase the visibility of and call attention to the crossing
provided they are warranted by an engineering study and approved by the City of
Eugene Traffic Engineer. Guidelines for implementing a mid-block crossing are
found in the Design Standards and Guidelines for Streets, Sidewalks, Bikeways, and
Accessways (provided in Appendix E and on the internet at www.eugene-or.gov).
F. Curbs
1. Elevation below 100-Year Flood
Top of curb shall be no more than 2 feet below the Federal Emergency Management
Agency (FEMA) designated 100-year floodway elevation.
2. Height
The standard required curb reveal is 6 inches.
3. Return Radii
Curb return radii shall be 20 feet for street widths equal to or greater than 28 feet, or
30 feet for street widths less than 28 feet; unless other radii is required to
accommodate pedestrians, emergency vehicles, buses, or trucks. Curb return radii
shall be designed to accommodate the largest design vehicle, as designated by the
City likely to use that facility, without driving over the curb and/or access ramps. If the
City grants an exception to this requirement, ramps and sidewalk which could receive
vehicle wheel loading shall be constructed with concrete at least 7 inches thick.
The designer shall demonstrate via modeling software (i.e., AutoTURN® or equivalent)
that the designated design vehicle can navigate all turns within the curbs on local
streets and within the travel lane on arterial and collector streets. The boundaries of
the turning path of the design vehicle when making the turn are established by the
outer trace of the front overhang and the path of the inner rear wheel. Regardless of
the designated design vehicle, the designer shall demonstrate a turning path having
Public Improvement Design Standards Manual, 2023 Page 2-20
at least a 30-foot inside radius and a 50-foot outside radius for emergency vehicle
turning movements between the opposing curbs.
The Owner/Developer shall provide sufficient right-of-way for sidewalk access ramps
and sidewalk using the appropriate curb radius within the scope of their project. See
Section 2.03 for the design requirements for sidewalks and access ramps.
G. Curves, Horizontal and Vertical
Horizontal and Vertical curves shall be of sufficient length to provide safe stopping sight
distances (SSD) based on design speeds and rate of vertical curvature (K) as determined
by the City Traffic Engineer and AASHTO road design standards (use “rounded for design”
values of stopping sight distance). On hillside residential streets, deviations from the
horizontal and vertical AASHTO standards may be allowed by the City Traffic Engineer
when conformance to AASHTO standards is not attainable due to physical conditions and
the Owner/Developer provides and installs MUTCD approved traffic control devices that
provide safe and efficient operation of vehicles for the proposed street design. For crest
vertical curves, the hill shall be signed with appropriate MUTCD warning signs and speed
advisory plates. (See Section 2.07 Traffic Control Devices for more information.)
H. Design Parameters: Speeds, Rates of Vertical Curvature, and Safe Stopping Sight
Distances
Design parameters for classified streets shall be:

Arterials 45 61 79 360
Public Improvement Design Standards Manual, 2023 Page 2-21
I. Future Street Extensions
Tentative grade designs for future extensions of curbs and alleys shall be shown on the
profiles and shall extend far enough to verify the proposed design (200 feet or through
the adjoining intersection).
J. Grades
1. Breaks
With the exception of grade breaks at driveways and access ramps, grade breaks shall
be used when the grade change at a station is:
1. 0.6 percent or less for Arterial streets;
2. 0.8 percent or less for Collector streets;
3. 1.0 percent or less for Local streets;
4. 1.25 percent or less for steep hillside streets; and,
5. 3 percent or less for alleys.
Vertical curves meeting AASHTO K values for the design speed shall be used at all
other times.
2. Curbs
Curb grades shall be established so that the Hydraulic Grade Line for the design storm
event is no less than 6 inches below the gutter at any point where water could
surcharge into the street (catch basins, curb inlets, manholes).
Curb grades across the throat of access ramps shall be designed to accommodate
sidewalk access ramps and shall not exceed 2 percent. (See Section 2.03 for more
information.
Curb grades along short-radius curves, such as curb returns and cul-de-sac bulbs, shall
be 0.5 percent or greater. See Appendix E for Cul-de-Sacs, Hammerheads, and
Emergency Vehicle Turnaround Standard Details.
3. Gutters
The minimum gutter grade shall be 0.40 percent. Grades of 0.30 percent may be
approved by the City to match existing curb grades.
Public Improvement Design Standards Manual, 2023 Page 2-22
4. Streets
The maximum street grade permitted in hillside developments is 15 percent, with the
following exception: grades in excess of 15 percent, but not more than 20 percent,
may be allowed for distances not exceeding 200 feet. Streets grades approaching
intersection pedestrian crossings shall transition using standard vertical curves (see
Section 2.05.L for pedestrian crossing slopes and Section 4.05.H for vertical curves).
5. Valley Gutters
The minimum grade on valley gutters shall be 0.4 percent.
K. Gutter Flow
To limit the width of storm runoff in street gutters to an acceptable value, regardless of
street grade, the maximum length of gutter allowed to carry surface flow is 400 feet or
one block, whichever is shorter. When the maximum length is reached, at least one curb
inlet or catch basin shall be provided to direct gutter flow to an approved stormwater
discharge system. The curb inlet or catch basin shall be located in such a manner that the
gutter flow is intercepted before crossing a pedestrian ramp.
To propose a greater length of gutter flow, the Project Engineer must submit calculations
to substantiate that such a design will achieve the same results. The maximum width of
gutter flow shall be 6 feet for streets equal to or greater than 28 feet wide or 4 feet for all
other streets. Calculate gutter flows using a 1 year 30 minute storm for computing gutter
flow is acceptable. Gutter flow at access ramps shall be a maximum depth of 1 inch. Curb
inlets will be required upstream of the ramps to reduce ponding at the ramp. (See Section
2.03 Access Ramps)
L. Intersections
Intersection design shall meet AASHTO stopping sight distance requirements (SSD) based
on the design speed of the facility. In addition to providing the SSD along each street,
corresponding sight triangles on each approach leg for an intersection must be provided
based on the type of approved intersection control. Local street intersections serving
adjoining residential-related traffic shall be designed to achieve sight triangles for
uncontrolled intersections as defined by AASHTO, i.e., intersections not controlled by
yield signs, stop signs, or traffic signals, unless otherwise approved by the City Engineer.
Traffic control devices shall be installed only when warranted by the MUTCD or the Traffic
Manual. (See Section 2.07 Traffic Control Devices)
Public Improvement Design Standards Manual, 2023 Page 2-23
Pedestrian access ramps at intersections shall be installed for current and future
crossings. If a statutory pedestrian crossing is to be closed deliberately, barriers and
MUTCD signage shall be required at signalized intersections, railroad crossings, and other
hazardous areas. Where access ramps are required, the access ramp and street crossing
area shall meet the requirements of Section 2.03. Intersection pedestrian crossings
between ramps shall not exceed 2 percent cross-slope perpendicular to the direction of
the pedestrian crossing (except the cross slope of crossings without “stop control”, which
shall not exceed 5 percent) for a width of 8 feet, and not exceed 5 percent running slope
in the direction of the pedestrian crossing. For mid-block crossings, the cross-slope of the
pedestrian crossing may match street grade, but the running slope in the direction of the
crossing shall not exceed 5 percent. (See Section 2.03 Access Ramps)
M. Intersection/Road Safety Analysis
An Intersection/Road Safety Analysis is required for public improvements that include
intersections identified as functioning at or near an unsafe level or roadway locations
where pedestrian and/or bicyclist safety is a documented concern by the City. The City
will review the Intersection/Road Safety Analysis and determine the required street width
and mitigation measures to improve pedestrian and/or bicyclist safety. The
Intersection/Road Safety Analysis shall include:
a. Average Daily Trips (ADT) of all legs of the intersection;
b. Street classifications of all intersecting roadways;
c. Presence of on-street parking;
d. Current (within past two years) peak hour (7 to 9 a.m. and 4 to 6 p.m.) turning
movement counts on all approaches to the intersection, and if within an industrial
area the count must break down vehicle classifications as percentages;
e. Delay-based level of service calculations using Synchro or HCM capacity analysis
methodology;
f. Crash history of the past three years (obtained from PWM Traffic Operations
compilation of DMV records); and,
g. Document concerns of pedestrian and/or bicyclist safety (obtained from PWM
Traffic Operations or PWE Transportation Planning).
N. Lighting
All new streets and bike paths shall include lighting. The lighting design shall be in
accordance with AASHTO, Illuminations Engineering Society of North America (IES) and
City of Eugene Standards. Lighting design and construction shall conform to the City
adopted requirement of the NEC. The lighting design shall include a lighting analysis and
shall comply with the Design Standards for Street Lighting provided in Appendix G, the
Public Improvement Design Standards Manual, 2023 Page 2-24
Standard Specifications and Drawings, and the following:
1. All new and retrofit luminaires shall be LED. Desired roadway placement is 3 feet into
the street beyond the curb.
2. Standards design for residential subdivisions shall utilize gray fiberglass poles
anchored in underground sleeves and gray cobra head LED luminaires producing an
IES Type II or Type III cutoff pattern.
3. The Design Engineer shall consult with the City to determine which lighting design is
appropriate for the roadway under design.
4. Standard design for arterial and collector streets shall include the following:
a. Arms and LED luminaires installed on existing utility company poles; or
b. Gray fiberglass poles anchored in underground sleeves and gray cobra head
LED luminaires producing and IES Type II of Type III cutoff pattern; or
c. Steel Hot Dipped galvanized poles with concrete foundations and gray cobra
head LED luminaires producing an IES Type II or Type III cutoff pattern.
5. Standard design for “great streets”, mixed use areas and nodal developments as
identified and defined in adopted planning documents requiring pedestrian scale
lighting shall use the standard predesign scale pole luminaire and concrete foundation
per City standards. The design may include a mixture of pedestrian scale lighting and
standard street lighting.
6. The lighting design analysis for arterial, collector, commercial and industrial streets
shall be in the form of computerized output from an industry-accepted lighting
package that includes calculated IES luminance levels, maximum-to-minimum
uniformity ratio, average-to-minimum uniformity ration, design fixture, input
wattage, light mounting height, light spacing, along with a plan view of the isocandela
lighting distribution. Minimum maintained average luminance levels, maximum-to-
minimum uniformity ratio, and average-to-minimum uniformity ratio shall be per the
following maintained luminance table.

8. Arterial streets shall have at least two lights at each intersection. On all other streets
at least one light is required at each intersection. Street light poles shall be placed to
meet IES lighting requirements or approved spacing table. Poles shall be staggered on
each side of the street and located on the inside of curves to the greatest extent
practicable.
9. Light poles shall be a minimum of 5 feet horizontal from driveway aprons.

fed from a utility power source does not require a formal service with breakers. This
is one light from one power source with no additional load. It is allowed to have two
lights from one power source if they are in separate conduits and they leave the
power company box and go different directions. All single supplied street lights shall
be controlled by photo-electric cell (PEC). Multiple street lights fed from a lighting
circuit shall be controlled by a single master PEC that operates contactors in the

the back side of the sidewalk.
32. Street light poles shall not be permitted in sidewalk areas unless right-of-way
constraints prevent other options and an exception is approved by City staff. If poles
are to be installed in a sidewalk area, they must provide a minimum clearance of 4
feet from either the face of the curb to the front edge of the pole, or from the rear
edge of the sidewalk to the rear edge of the pole.

sections shall be provided at 50-foot intervals where a constant cross slope is not
maintained.
S. Pavement Design
1. Asphalt-Concrete (AC) Pavement
New AC pavement and AC reconstructions (both described below as “new pavement”
or “new streets”) shall be designed as described herein. The design method for new
pavement and for pavement rehabilitation and strengthening of existing streets shall
be as described in the 1993 AASHTO Guide for Design of Pavement Structures (1993
AASHTO Guide) with the 1998 supplement; with the following exception: the City’s
nomographs provided in Appendix F may be used for new and reconstructed streets
classified as local streets or neighborhood collector streets. Software to calculate
pavement depth using the AASHTO-approved methodology is available online at
www.aashtoware.org. The design requirements below apply to new pavement and
pavement rehabilitation/strengthening.
New AC pavement and AC reconstructions may be designed as “full-depth” AC
pavements if recommended by a pavement engineering report and supported by soil
characteristics testing and soil support testing. Full-depth asphalt concrete pavement
is asphalt concrete paved directly on a compacted firm and unyielding subgrade
without a base rock layer other than an optional 2-inch to 4-inch leveling course as
desired.
Full depth AC design is used to minimize subgrade excavation during construction in
areas where AC construction work can be supported by untreated or stabilized
subgrade. Full depth AC design may be proposed for AASHTO subgrade soil types A-1
through A-4. Full depth design may also be proposed for AASHTO soil types A-5
through A-6 provided that soil testing and/or falling weight deflectometer (FWD)
back calculation data proves that the resilient modulus is at least 7,500 psi, or, in
Public Improvement Design Standards Manual, 2023 Page 2-31
areas where the subgrade can be improved during construction through either
scarification and compaction or soil treatment, a geotechnical report provides
recommendations for the scarification-compaction process or the soil amendment
process. Full depth AC may also be proposed with aggregate subbase on
geotechnical fabric instead of soil treatment.
Full depth design shall assume the full-depth AC paving supports the full traffic
loading. Any treated subgrade or aggregate subbase shall be considered a working
platform for construction and not a structural element of the pavement structure in
the pavement design.
Design parameters for the AASHTO-approved method for flexible pavement (SN =
a1D1 + a2D2M2 + anDnMn) are reflected below. The pavement section shall be designed
using the Layered Design Analysis method described in Section 3.1.5 of Part II of the
1993 AASHTO Guide.
Design traffic, ESAL’s, is the expected number of equivalent single axle loads to the
pavement over the design period. For all street classifications the design period for
new streets, portions of new streets, and rehabilitation of existing streets to fully
reconstruct or to remove and replace pavement shall be 30 years, and 20 years for
overlays and “mill and fill” street rehabilitation. Design ESAL’s shall be calculated per
the current ODOT Pavement Design Guide. Annual growth rate shall be 1.5 percent.
Table 1, ESAL Annual Conversion Factors, shall be replaced with the following:
Table 1 – ESAL Annual Conversion Factors

Articulated Bus 1550 775 2320 1160
Serviceability (psi) is the ability of the pavement at the time of observation to serve
high-speed, high volume vehicular traffic. Use the following factors.
Initial psi = 4.2
Terminal psi = 2.5
Public Improvement Design Standards Manual, 2023 Page 2-32
Reliability (R) is the probability that the pavement section designed using the design
method will perform satisfactorily for the traffic and environmental conditions that
actually occur during the design period. Use the following values:
Street Classification Design Reliability
Arterials 90 Percent
Collectors 90 Percent
Neighborhood Collectors and Local streets 95 Percent
Overall standard deviation (S) accounts for the designer’s ability to estimate the
variation in the equivalent axle loads. Use the following value:
S = 0.5 for flexible pavement
Subgrade support (Mr) is measured by the soil resilient modulus, the strength of the
soil. Follow the 1993 AASHTO Guide for correlations of the Mr to other soil properties.
Soil support values shall be determined from soil tests, however, an “R” value of 5 or
a Mr value of 3775 will be accepted for design purposes without verification by soil
testing. Soil support values may also be back calculated from falling weight
deflectometer (FWD) tests.
Drainage coefficient, mi is the effect of moisture in the layer of material. The following
values shall be used:
Crushed rock 1.0
Sand, gravel 0.6
Layer coefficient (a#) is the contribution of the pavement layer to the structural
number per inch of thickness. Use the following coefficients for pavement design.
Subbase coefficient (a3)
Crushed rock 0.08
Lime-treated soil 0.11
Cement-treated soil 0.11
Base coefficient (a2)
Crushed rock 0.10
In-place cement treated base (ICTB)* 0.16
Plant mix cement treated base (CTB) 0.22
Public Improvement Design Standards Manual, 2023 Page 2-33
Bituminous treated base (BTB) 0.22
*Layer coefficient for ICTB may be used where at least 50 percent, by weight, of
the existing material to be treated is granular.
Surface Course coefficient, all lifts (a1)
Plant mix AC 0.42
Minimum Thickness – Should the pavement design result in a thickness less than
shown in the table below, the minimum AC pavement thickness required shall be as
shown below:
Street Classification Minimum Thickness
Local or Neighborhood Collector 6 inches
Local or Neighborhood Collector w/bus route 8 inches
Major Collector 8 inches
Arterial 9 inches
Round pavement thickness calculations up to the nearest half-inch (0.5”). The
minimum AC thickness for Local and Collector streets listed above may be decreased
by up to two inches (as calculated using the layer coefficients above) if ICTB or CTB
(place CTB on subgrade fabric) a minimum of 10 inches thick with a 7 day strength of
between 300-500 psi is constructed as a base layer for the AC.
Treated subgrade, ICTB, or a layer of aggregate subbase or base material or cement
treated base over subgrade geotextile shall be included under the pavement section
in the construction plans as a working platform for construction in the following
situations:
1. Where soils testing has been performed and one or more of the following
conditions apply:
a. The report indicates that the soils are weak; and/or
b. The report states the soils will not be compactable to Standard
Specifications requirements; and/or
c. The report states the soils will be prone to pumping during the
construction period; and/or
d. The subgrade soils do not meet compaction and/or deflection
requirements during construction.
2. Where the designer has not performed soils testing and has assumed soil
strength R=5 (or Mr = 3775) for design purposes.
Public Improvement Design Standards Manual, 2023 Page 2-34
The minimum thickness of the construction working platform layer shall be as shown
below, and shall be thicker if necessary to achieve the minimum specified compaction
and maximum deflection requirements.
If a treated subgrade, an ICTB or CTB is proposed, a full pavement design shall be
performed which also includes a mix design for the treated subgrade, ICTB or CTB to
establish the thickness of treatment, the percent cement, the optimum water
content, and the maximum density of the treated subgrade, ICTB or CTB. The
minimum thickness of the working platform shall be as follows: 12 inches for
aggregate sub base or base; 10 inches for an ICTB or CTB; and 12 inches for treated
subgrade. The purpose of treatment of the subgrade will be to make the material
compactable, so there is no minimum strength requirement, however, the maximum
strength shall not exceed 500 psi. The 7 day design strength for ICTB and CTB shall be
between 300 psi and 500 psi. Construction of the treated subgrade, ICTB or CTB shall
comply with special specifications to be supplied by the City.
Asphalt Concrete Mix Formulas
Select the level of AC mix to be specified for construction based on the design ESAL’s
for the life of the pavement. If design ESAL’s for the street to be paved exceed 10
million, the mix design and criteria for the mix shall be prepared by a licensed
Professional Engineer with specific experience in pavement design.
ESAL’s Mix Criteria
< 10,000 Level 1
10,000 to 1 million Level 2
>1 million, <10 million Level 3
2. Portland Cement Concrete (PCC)

1993 AASHTO Guide for Design of Pavement Structures (1993 AASHTO Guide) or
Portland Cement Association (PCA) approved design specifications. Use the
parameters from the 1998 Supplement design method listed in the following table
with notes on their suggested values and/or documentation of where the values come
from or can be obtained. Design traffic loading shall be calculated as shown above in

2. See page 21 in 2007 ODOT Design Guide.
3. This is rounded from the value of 0.39 that ODOT uses (see page 22 of the 2007 Design Guide)
since the accuracy of estimating the standard deviation doesn’t warrant distinction between
0.39 and 0.40.
4. Based on 600 psi flexural strength requirement in Section 02001.33 of the 2008 ODOT
Specification for Class 4000 paving concrete.
5. Computed from 600 psi flexural strength using formula: Ec = 26454*S’c0.77 from formula
shown in example on page 45 of the 1998 Supplement.
6. Value shown is for aggregate base per 2007 ODOT Design Guide. Mid-range values from Table
14 of the 1998 Supplement would also be acceptable.
7. Derived from Fig. 40 in AASHTO 1998 Supplement for A-4 to A-7 soils at 95% saturation to
approximate the default R value of 5 used for flexible pavement. Exception: If soil testing is
performed to determine the actual k-value, the actual k-value may be used. Submit testing
reports to the City for review.
8. From AASHTO 1998 Supplement.
9. Assumes no slab edge support. Factor varies from 0.92 to 1.00 depending upon degree of
edge support as noted on page 20 of 1998 Supplement.
10. Mean value from Table 14 in 1998 Supplement for aggregate base.
11. Used to compute temperature differential within the slab per Eq 48 of 1998 Supplement for
positive differential and Eq 51 for negative temperature differential. Data is from the National
Public Improvement Design Standards Manual, 2023 Page 2-36
Weather Service Climate Summary for Eugene available at the following link:
http://www.wrh.noaa.gov/pqr/climate/eug_clisummary.php.
12. Value is middle of range given on page 46 of 1998 Supplement for wet climate. Value is used
to compute negative temperature differential for checking tensile stress in top of slab for axle
loading near undoweled transverse joints.
13. Value from NOAA 29-yr average for Eugene Airport. Value used in faulting predication models.
14. Value based on August normal maximum of 81.8 °F and January normal minimum of 35.2 °F.
Value is used in the doweled joints faulting prediction model.
15. Value from National Weather Service Climate Summary for Eugene. Value is used in un-
doweled joints faulting prediction model.
The final step of the design is to estimate the magnitude of joint faulting at the end of the
design period using the predicative models in 1998 Supplement for doweled or
undoweled joints. Analyze joint faulting for a 30 year period. Adjustment to the design is
required if the 30 year predicted faulting magnitude exceeds the critical values given in
Table 28 of the 1998 Supplement. Potential adjustments include use of treated base
material and use of subdrains to improve drainage conditions.
The design life for PCC pavement shall be a minimum of 40 years for local streets,
neighborhood collectors, and major collectors and a minimum of 50 years for arterials.
The design shall assume the PCC carries the full traffic loading. If aggregate base or
cement treated subgrade is used it shall be considered a working platform. Pavement
design for streets shall factor in the Contractor’s use of the pavement structure during
construction. The pavement design shall consider the use of the subgrade and base by
construction vehicles and equipment and include, as needed due to soil conditions or
other factors, design and construction of an aggregate base working platform in order to
avoid subgrade damage or failure. Prior to beginning the design analysis the designer
shall consult with the City to identify the appropriate post-construction design vehicle or
vehicles (e.g., City, utility company, emergency vehicles etc.). A narrative discussion of
how the design vehicle(s) were accommodated in the design must be included in the
analysis report.
The minimum 28 day compressive strength for PCC shall be 4000 psi for all streets,
accessways and alleys. No vehicles, including construction equipment, shall be permitted
to use the pavement until it has reached its full design strength. If the designer intends
for the street or alley pavement to be used prior to achieving its full design strength, the
design report shall include verification that the structural design of the pavement will
accommodate the proposed uses at the strength specified below without damage to the
pavement. In the case of this design verification, the street or alley pavement may be
used after it has achieved at least 70 percent of design strength. When design analysis
yields a design thickness less than shown in the table below the following minimum
Public Improvement Design Standards Manual, 2023 Page 2-37
thicknesses shall be used: Round pavement thickness calculations up to the nearest
1/2inch.
Classification Minimum Thickness
Alleys 7 inches
Accessways 7 inches
Local Streets without Bus Route 7 inches
Local Streets with Bus Route 8 inches
Collector Streets 9 inches
Arterial Streets 10 inches
The designer shall provide a jointing plan for PCC paving of streets in the construction

tie bars and other reinforcement where required. The jointing plan shall also include a
title, legend, engineer’s stamp, general notes, joint details and sawing depths. Joint layout
shall be designed in accordance with American Concrete Pavement Association (ACPA)
recommendations and requirements contained in this section. The designer shall
minimize or eliminate joints that intersect another joint at the pavement edge at an acute
angle. The designer shall avoid angles of less than 60 degrees. No skewed joints shall be
allowed within mainline paving areas. Joints shall be saw cut, except as required by the

inches or more in thickness. The length to width ratio for any panel shall be at least 0.75
and shall not exceed 1.25.
Longitudinal joint spacing shall not exceed two times (2x) the slab thickness in feet up to
a maximum of 15 feet, see below for examples:
PCC Thickness Maximum Joint Spacing
7 inches 14 feet
8 inches or thicker 15 feet
PCC street paving shall either be reinforced pavement or shall be “plain” PCC with dowels
and tie bars to reinforce the joints. Dowel bars shall be placed across the transverse joints
and deformed tie bars shall be placed across longitudinal joints. In intersections, dowel
Public Improvement Design Standards Manual, 2023 Page 2-38
bars shall be placed in all joints. Panels adjacent to concrete curb and gutter or curb shall
be tied to the gutter, or curb in absence of a gutter, with deformed tie bars. Dowel and
tie bar sizes and placement shall be as per the Standard Drawings. Joint reinforcement is
not required for alleys except as required by the pavement design.
If aggregate base is not required as a working platform per the pavement design a leveling
course of a minimum of 2 inches of compacted 3/4 inch-minus crushed rock shall be
placed before the concrete pavement is poured.
Requirements, limitations and provisions for a working platform for construction shall be
as described above in the AC subsection.

depth of 2 feet of topsoil meeting the requirements of the Standard Specifications shall
be placed within the planting strips where compaction, excavation, contamination or
disturbance is expected. An 18” depth of topsoil may be allowed at lateral utility
crossings. The planting strip is the area between the back of curb and the existing or
proposed future sidewalk location. The cross sections shall identify the planting strip
areas and provide callouts directing their protection and/or replacement.
U. Private Streets
Private streets, and related features such as drainage systems and street lighting, shall be
privately maintained and identified as such on the construction drawings. As with other
private construction, a PEPI permit does not authorize construction of private streets nor
its infrastructure. Construction permits for private streets and its infrastructure is through
the Permit and Information Center, Atrium Bldg. 99 West 10th Avenue.

hour (MPH).
2. Taper is preferably placed in a curve.
3. Shorter tapers may be allowed where the taper widens in the direction of
traffic flow.
4. A taper is not needed if a transition includes an intersection, as long as the
driver has to stop before turning or proceeding from a wider street onto a
narrower street.
5. When connecting to an intersection, the taper must end at a point that
provides a minimum of 25 feet from the curb return.

Public Improvement Design Standards Manual, 2023 Page 2-42
D. Signals / Electrical Traffic Control Devices
1. These devices shall meet warrants for installation or have a TIA that indicates that
warrants will be met upon installation.
2. All traffic signals and other electric traffic control devices must meet current National
Electric Code (NEC) and National Electric Safety Code (NESC) requirements.
3. All traffic signals shall be of mast arm support design unless a specific exemption is
granted (e.g., temporary signal installation).
4. All signal poles must be designed within the right-of-way and be placed to keep
sidewalks and ramps clear. Signal poles must be designed for optimum ADA usability.
5. All new or modified actuated traffic signals shall include Audible Pedestrian Devices
(APD) and Countdown Pedestrian Signals. Pedestrian signals shall be designed using
the Standard Specifications and Drawings and the “Accessibility Guidelines for
Pedestrian Facilities in the Public Right-of-Way” as published in 36 CFR Part 1190.
6. All traffic signals shall utilize a 2070E traffic signal controller in a 332 cabinet. It shall
utilize the City of Eugene Voyage software package and shall connect to the City’s
master traffic signal system.
7. Inductive loop design is the preferred method of traffic actuation. Video detection
may be considered when design considerations are optimal or when inductive loop
detection would not function as well as video detection.
8. Minimum size of conduit shall be 1 and ½ inches except that 1 inch will be allowed to
a push button detection post.
9. Maximum conduit fill design shall be 25 percent.
10. Junction box (JB) fill shall not exceed NEC. The maximum number of conduits installed
in any one box will be determined by the cumulative diameter of the conduits, subject
to the following maximums: JB1, 8 inches; JB2, 16 inches; and JB3, 24 inches.
11. The utility service point shall be located in the public right-of-way or in a PUE directly
adjacent to the public right-of-way. A PUE is defined as the standard 7-foot or 10-foot
roadside utility easement. Maximum voltage drop from the utility service point to the
Public Improvement Design Standards Manual, 2023 Page 2-43
service cabinet shall not exceed one (1) percent. Maximum voltage drop from service
cabinet to the furthest point of the system shall not exceed two (2) percent.
12. All wiring for the traffic signal shall be IMSA cable for signals, 3M Opticom wiring for
emergency vehicle preemption, UF for street light conductors, and XHHW for service
wiring.
13. The traffic signal service shall be a 120 volt service with meter socket that includes a
blank cover and jumper clips. Street lighting at the intersection shall be 120 volt and
include a PEC on each fixture.
14. Interconnect cable shall be 22 Gauge PE39 Cable.
15. New installations and modifications require the installation of temporary “Caution
New Intersection Control” signs.
16. Foundations shall be designed pursuant to the criteria on the City of Eugene Standards
Drawings and the ODOT Traffic Structures Manual.
The details for the mast arm foundations are shown on ODOT Standard Drawing
TM653. The depth of the foundation must be designed using site specific
recommendations from a Geotechnical Engineer and the most current AASHTO
Standard Specifications for Structural Supports for Highway Signs, Luminaires, and
Traffic Signals with all interim revisions.
The drilled shaft (or other deep foundation) design must produce a foundation
embedment depth equal to or exceeding the embedment depths resulting from the
use of the Brom’s method as stated in the commentary of Section 13.6.1.1 of the
AASHTO Standard Specifications. The under-capacity factor to use is 0.7, the minimum
overload factor to use is 2, and a 1.33 stress increase factor may be applied. This
results in the working stress reactions, as shown on TM651, to be increased by a
minimum safety factor equal to [(2/0.7) / 1.33] = 2.15. Using the Brom’s method to
design the depth of signal foundations with the overturning moment and shear will
provide adequate resistance for applied torsional loads.
Figures 2-1 through 2-3 in the ODOT Traffic Structures Design Manual provide
foundation depths for the standard types of signal pole mast arms as a function of soil
type (either cohesionless or cohesive) and soil strength. Figure 2-1 shows foundation
depths calculated for a cohesionless soil without any groundwater. Figure 2-2
provides foundation depths for cohesionless soils that are completely under water
Public Improvement Design Standards Manual, 2023 Page 2-44
(totally saturated condition). Figure 2-3 provides a table of foundation embedment
depths calculated for cohesive soils. Those figures may be used in calculating
foundation depths for standard types of signal pole mast arms as a function of soil
type and soil strength, and as indicated in the ODOT Traffic Structures Design Manual.
E. Temporary Traffic Control
Appropriate temporary traffic control is essential for the protection of workers and the
public utilizing the public rights-of-way during construction. Temporary traffic control
devices are required to be in place prior to construction activities on or near the public
way. These devices are required to be shown on a Traffic Control Plan consistent with the
latest editions of the MUTCD, ODOT’s Oregon Temporary Traffic Control Handbook and
Standard Specifications, and the “Accessibility Guidelines for Pedestrian Facilities in the
Public Right-of-Way” as published in 36 CFR Part 1190, subject to City review and
approval.
2.08 WASTEWATER
Public wastewater systems shall be designed and constructed in accordance with the City’s
Wastewater Master Plan, Standard Specifications, Eugene Code Chapters 6 and 7, applicable
appendices of this manual, and the following standards. It is also noted that vertical and
horizontal separation between wastewater lines and water lines shall be maintained in
accordance with DEQ regulations (available at www.deq.state.or.us).
A. Analysis (Wastewater Study)
A wastewater study shall be prepared for all wastewater systems that include pipe sizes
greater than 8 inches or where additional properties may be served by an extension of
the system. The study shall include, but not be limited to, a study map, wastewater flow
calculations, and pipe hydraulic calculations. The wastewater study shall be prepared in
accordance with standards of this manual and in a manner such that the information is
readable when electronically scanned.
The wastewater study map shall include, at a minimum, the following:
1. Streets and street names.
2. Lot lines.
3. Contours or other form of ground surface elevation information.
Public Improvement Design Standards Manual, 2023 Page 2-45
4. Proposed and future pipe system, complete with manholes, pipe slopes, manhole
flow line elevations, pipe sizes.
5. Ultimate service area boundaries (from Wastewater Master Plan and consultation
with the City).
6. Sub-service area boundaries, each individually highlighted in some way.
7. Legend details such as, but not limited to, north arrow and scale.
8. Company name, designer’s name, and date.
9. Demonstration that all buildable areas within the development can be served.
B. Design Approach
Wastewater service shall be extended in conformance with the approved waste water
basin master plans. Public mains shall be extended at minimum slope unless an
engineering study demonstrates the basin can be adequately served by steeper grades or
shallower mains. Wastewater mains shall be extended to the limits of the development
served for the purpose of future extension unless an engineering study demonstrates
service is already available or an alternate service route is more efficient.
The minimum pipe diameter for wastewater mainline is 8 inches. 6-inch pipe may be used
on residential mainlines in the most upstream reach, if the length of the reach is less than
250 feet and if no more than 4 single dwellings are served.
The minimum desirable slope for a 6-inch mainline system is 1 percent and for an 8-inch
mainline system is 0.40 percent. The minimum desirable cover is 5 feet at the extreme
upstream manhole in a service area; additional cover requirements may apply. The
maximum desirable design flow depth is 80 percent full. The minimum design velocity is
2 fps.
Notwithstanding minimum design velocity, the City may approve the following
adjustment: 8-inch pipe slopes may be flatter than 0.40 percent only if necessary to
maintain flow line depths to serve all lots in the service area.
8-inch pipe slopes may be steeper than 0.40 percent where maintaining flow line depth
is not a design control. Where the system is not intended to be extended in the future,
the slope of the last segments should be between 1 percent and 5 percent to achieve
cleansing velocities.
C. Manholes
1. Pipe Grades and Channel Slope
Public Improvement Design Standards Manual, 2023 Page 2-46
Manholes shall be designed to minimize head loss through the structure. The crown
of the pipe existing the manhole shall not be higher than the lowest crown of the pipe
entering the manhole or 80 percent of the flow depth of the pipe exiting the manhole
shall not be higher than the lowest 80 percent flow depth of the pipes entering the
manhole.
A 0.1-foot drop through the manhole shall be provided from upstream inlet and the
manhole outlet (2.9 percent slopes). For steep systems where pipe slopes are greater
than 3 percent the upstream pipe slope shall be carried through the manhole to the
outlet flow line elevation. A maximum drop of 24 inches is allowed through the
manhole.
2. Drop Manholes
Elective use of drop manholes is to be minimized and limited only to situations when
public wastewater is very deep, in areas of known high groundwater, or if dense
rock is encountered. The Project Engineer shall demonstrate the use of a drop
manhole shall not limit extension of gravity service to the wastewater basin.
A drop manhole is required where the drop through the manhole channel is
proposed to exceed 24 inches. External drop manholes are to be used as first
priority. Internal drop manholes may be used in situations where structural, utility or
topographical challenges prohibit the use of an external drop manhole.
3. Locations
Manholes shall be installed at the following locations:
• End of each main line,
• At all changes in grade, size or alignment (vertical and horizontal),
• At distances not greater than 400 feet. Greater spacing may be permitted in
large diameter wastewater lines as approved by the City.
Manholes shall be positioned outside normal wheel travel paths (centered in the lane
or between lanes) and outside the center of an intersection where the turning path
of vehicles may place a wheel path over them.
4. Size and Materials
See the Standard Specifications for Construction and Standards Drawings for
required manhole type, size and material properties.
Public Improvement Design Standards Manual, 2023 Page 2-47
5. Shallow Manholes
A flat top of shallow cone shall be used when there is less than 5 feet of cover over a
pipe.
6. Watertight Manhole Covers
Watertight manhole covers shall be used when the cover is either below the 100-year
flood plain or in a location where overland runoff or gutter flow or other concentrated
flows or water from ponding areas could enter the manhole.
D. Off-Site Flows
When land outside a new development will direct flow to wastewater systems in the new
development, the systems shall be public and constructed to one or more of the
development boundaries. The system shall be sized and located to accommodate all off-
site flows. Guidelines for the extension of the public wastewater system can be found in
the most current version of the City’s Wastewater Master Plan.
E. Pipes
Pipes shall comply with the following:
1. Cover
4 feet of cover shall be provided over the top of the pipe from expected finish grade.
Where pipe cover is proposed to be less than 4 feet or more than 10 feet, the Design
Engineer shall provide documentation and/or design calculations to show that the
pipe is structurally adequate to withstand construction loadings and traffic loading.
Notwithstanding the above guidance, a CLSM cap shall be required where the top pipe
is within 2 feet of finished grade.
2. Curves, Horizontal and Vertical
Horizontal and vertical curves are not permitted except in steep terrain, and then
only:
a. One horizontal curve is permitted between any two manholes provided there
is no vertical curve in that section; or,
b. A maximum of one (1) vertical curve is permitted between any 2 manholes
manhole.
Public Improvement Design Standards Manual, 2023 Page 2-48
c. Joint deflections shall not exceed pipe manufacturer’s recommendations.
3. Manning’s Roughness Coefficient (“n” Value)
“n” value for PVC and HDPE pipe shall be 0.010.
“n” value for concrete pipe shall be 0.013.
“n” value for metal pipe is specified in Appendix I.
4. Materials
Wastewater pipe designed for open channel flow shall be PVC or ductile iron.
Wastewater pipe designed for pressurized flow may be PVC, ductile iron or solid wall
HDPE.
Pipe networks in streets shall be designed parallel to street centerlines whenever
possible. Skewed pipe alignments are discouraged.
5. Buoyant Forces
The effect of buoyant forces shall be checked for all pipes used below the normal
water table. Buoyant forces shall not be greater than the weight of the pipe and
backfill.
F. Pump and Lift Station Design
Public pump and lift stations must be identified in the City’s Wastewater Master Plan or
otherwise deemed appropriate by the City. Pump and lift stations require specialized
planning, engineering and specifications not specifically addressed in detail by this
manual or the Standards and Specifications. Stations shall meet the specific design and
maintenance requirements of the City of Eugene in addition to the basic requirements of
the Department of Environmental Quality (DEQ) pump station design regulations
available at www.deq.state.or.us.
Consultants must be experienced in the design and construction of large (1 MGD +)
sewage lift stations. An interdisciplinary team is expected to address the multiple
disciplines necessary to design and deliver the station. A pre-design report that outlines
the scope of the project from design through construction is required and shall be
approved by the City of Eugene. The pre-design report shall include, but not be limited
to, the following information:
Public Improvement Design Standards Manual, 2023 Page 2-49
• A list of the required engineering disciplines
• Basin Study and design flows
• Wet well calculations

G. Service Lines
Provide independent connections to the public wastewater system to all lots and parcels.
Service lateral pipes within the public rights-of-way shall be a minimum of 6 inches.
Private service lateral pipes located in public easements may be a minimum of 4 inches
and be constructed and extended to the back of the public utility easement (PUE) with
the public construction permit for the public mainline. A 6-inch public service extending
from the mainline to the property line is adequate to serve 3 lots. The extension of the
public wastewater system shall be required when more than 3 residential lots are to be
served by the system.
Service laterals shall:
• Connect into manholes wherever possible.
• Connect directly to the mainline at right angles where blind connections are
allowed.
• Connect into a manhole where the lateral approaches the mainline at greater
than 30 degrees from perpendicular.
• Connect to the mainline with a manhole where the lateral is 8-inch diameter
and greater.
Laterals may:
• Connect to a mainline with a blind connection when the diameter of the
lateral is twice the size of greater than the diameter of the mainline.
• Connect into a manhole where the lateral approaches the mainline at greater
than 30 degrees from perpendicular.
Public Improvement Design Standards Manual, 2023 Page 2-50
All service lines 8 inches and larger shall require the construction of a manhole for
connections to the mainline. 4-inch and 6-inch blind connections are acceptable. 8-inch
and larger blind connections are acceptable where the mainline diameter is twice the
diameter of the service lateral or greater.
A cleanout is required, per Standard Drawing RD-310, when two or more services are
provided on a 6-inch service line. Each 4-inch service outside of the right-of-way shall have
a private easement if crossing an adjoining property. Use of inside drops are to be
minimized, limited only to situations when public wastewater is very deep, in areas of
known high ground water, or if dense rock is encountered.
Tops of service line pipes shall be 4 feet to 6 feet below finished grade at the property
line in accordance with the Standard Drawings.

SECTION 4 - PRIVATE ENGINEERING AND CONSTRUCTION PROCESS
4.00 INTRODUCTION
The City permits public improvements to be privately-engineered and constructed via the
“Privately Engineered Public Improvement (PEPI)” permit process. Such improvements are
typically development-driven, whereas public improvements designed by the City are usually
community-driven. As discussed previously in this manual, design standards for public
improvements are to be implemented consistently between the private and public sector;
however, there are certain procedures specific to the private process (the PEPI permit), which
are outlined in this section. Also refer to Appendix L for standard forms and other resources
specific to the PEPI permit process.
4.01 PRE-APPLICATION CONSIDERATIONS
Prior to submitting PEPI plans for review and approval, applicants are encouraged to meet
with City staff and consult other utility providers to determine potential conflicts in advance
of preparing the detailed design drawings.
A. Staff Consultation
Engineering staff will meet up to 2 hours with applicants and project engineers to discuss
design and project issues. If staff consultation time exceeds 2 hours, an “Engineering and
Construction Agreement” (provided in Appendix L) will be required in advance of
construction plan submittals to recover staff expenses. See Section 4.10 Financial
Responsibilities.
B. Facility Coordination
Proposed facilities must be consistent with the City’s master plans and avoid conflicting
with existing utility locations. The City will review PEPI plans for conflicts with City-owned
street, wastewater, and stormwater infrastructure, and defers to utility companies and
the applicant to resolve conflicts with electric, water, telephone, gas, and television utility
infrastructure and private facilities. In some cases, subject to approval, the applicant may
need to relocate utilities. The cost of relocating utilities shall be borne by the applicant.
As-construct information for City-owned infrastructure is available at the Permit and
Information Center, 99 West 10th Avenue; wastewater and stormwater hydrologic and
hydraulic study information may be available at the City Engineering office, 99 East
Broadway, Suite 400; research and copy fees may apply.
Public Improvement Design Standards Manual, 2023 Page 4-2
Other information should be obtained directly from utility owners (see Appendix L for
contact information). The applicant will be required to resolve any conflicts directly with
the utility owner; additionally, written concurrence from each utility will be required prior
to City approval of the PEPI plans, in accordance with Section 4.08 Concurrences.
4.02 APPLICATION REQUIREMENTS
The following information is required for the City to process the PEPI permit.
A. Engineering and Construction Agreement
The Owner/Developer shall submit a signed "Engineering and Construction Agreement"
(see Appendix L). This agreement defines the scope of work and confirms that the public
improvements will be privately engineered, constructed and financed. This agreement
obligates the Owner/Developer to reimburse the City for costs incurred to complete the
project. See Section 4.05 City Engineering Services and Section 4.10 Financial
Responsibilities for more information.
B. Supporting Analyses
1. Geotechnical Analysis is required of all PEPI projects; refer to Appendix C for
report requirements.
2. Stormwater Analysis is required to demonstrate compliance with the
standards in Appendix J as noted in Section 2.04 of this manual.
3. Wastewater Analysis is required as noted in Section 2.08 of this manual.
4. Pavement Design Calculations are required for all new streets as noted in
Section 2.05.
5. Street Light Analysis is required for all new streets as noted in Section 2.05.
6. Traffic Signal Warrant Analysis is required, when applicable, as noted in
Section 2.07.
7. Pipe-Load Calculations are required as noted in Section 2.08.
8. Critical Root Zone Impact analysis is required with tree preservation. See
Section 3 regarding natural resource area mapping required on Construction
Site Management Plans. For additional information on applicable tree
regulations, refer to Appendix D.
Public Improvement Design Standards Manual, 2023 Page 4-3
9. “No-Rise” Certification is required with a Floodplain Development Permit for
work within a Floodway. See Appendix B for permit requirements.
C. Construction Plans
Construction plans shall be prepared consistent with the drafting standards in Section 3.
Paper review or electronic plan review is provided by the City of Eugene. For paper review,
one paper copy shall be submitted to the City for review along with an electronic version
in a PDF format. For electronic plan review, one set of CAD generated PDF’s shall be
submitted. The Project Engineer shall design and prepare the construction plans for public
improvement(s) in accordance with this manual, and include the following plans.
1. A Construction Site Management Plan (CSMP) is required of all PEPI projects.
The CSMP identifies measures to be implemented during construction to avoid
impacts to water quality and natural resources, such as trees, waterways, and
other natural features. The CMSP does not authorize construction, fill or
removal of features. Other permits may be required, such as: Erosion
Prevention Permit, Floodplain Development Permit, tree removal permit,
wetland fill permit, or land use applications for impacts to local resources. See
Appendix A for applicable regulations and CSMP notes required. Also refer to
Section 3 for drafting standards and other required plan information.
2. Street lights are required of all new street construction, as noted in
Section 2.05. Street light plans shall be submitted consistent with the
drafting standards in Section 3. Approval by EWEB is required before the
City will issue the permit. See Appendix G for standard details.
3. Traffic control devices may be required of street projects, as noted in
Section 2.07. Traffic control devices shall be submitted consistent with the
drafting standards in Section 3. See Appendix H for standard details.
(Traffic control plans for temporary devices used during construction are
addressed below at Section 4.13).
4. Trees to be preserved shall be identified on the construction plans and on the
CSMP as noted in Section 3. Protection measures shall be in place through the
duration of construction, in accordance with adopted City administrative rules
and tree protection guidelines. See Appendix D and the Standard Drawing for
tree protection.
5. Access ramp designs shall be as described in Section 2.
Public Improvement Design Standards Manual, 2023 Page 4-4
4.03 PLAN REVIEW AND APPROVAL
A. Objectives
In addition to reviewing the applicant’s submittal for compliance with applicable
standards, the City Engineer’s comments and requirements are intended to protect the
needs of the following:
1. The Owner/Developer, by requiring good engineering practices and
economical designs.
2. The private design team, by providing clear and early direction concerning City
requirements.
3. The public, by eliminating unsafe elements of the design.
4. Future owners, by requiring compliance with special flood hazard standards
and other applicable development regulations.
5. Adjacent property owners, by ensuring that wastewater service, drainage
facilities, and street access are provided through the project area to adjacent
properties.
6. Public Works Maintenance and Parks and Open Space divisions, by requiring
designs that minimize maintenance costs and provide maintenance access.
7. The City Inspector, by requiring clear, complete, and accurate plans that do
not require the Inspector to make field design decisions.
B. Process
Any needed plan edits will be sent to the Project Engineer generally within three weeks
following receipt of a complete submittal. After making the requested changes, the
Project Engineer will need to resubmit one (1) set of revised plans for a follow-up review.
When the plans have met the approval criteria below and are acceptable to the City
Engineer, the original drawings will be stamped "Approved" by the City. (See Appendix L
for process flow chart.)
C. Approval Criteria
In addition to PEPI plans being prepared in accordance with applicable design and drafting
standards of this manual, construction plan approval is contingent upon compliance with
the following criteria.
Public Improvement Design Standards Manual, 2023 Page 4-5
1. Land Use Decisions
Concurrent planning applications need to be approved as stipulated in Section
4.08 Concurrences.
2. Concurrence from Internal and External Utility Owners
Although the City will help facilitate plan-review coordination and resolution
amongst affected utility owners, the Owner/Developer is ultimately
responsible for obtaining concurrence pursuant to Section 4.08.
3. First Public Notice
Documentation that the first public notice, as required by Section 4.09
Public Notification, has been mailed must be submitted to the City.
4. Payment of City Fees
Prior to plan approval, all project-related fees up-to-date must be paid.
See Section 4.10 Financial Responsibilities.
5. Draft Documents
Submit draft maintenance agreements, right-of-way and public easement
dedications, and all other documents that need to be recorded prior to permit
issuance for City review and comment prior to PEPI plan approval.
Approval of the plans is effective for one year. Thereafter, a new Engineering and
Construction Agreement and Permit Application must be signed and submitted with updated
plans compliant with the Standard Specifications and Drawings.
4.04 CONSTRUCTION PERMIT CONDITIONS
Approved PEPI plans do not authorize construction; construction cannot commence until the
City issues a Public Improvement Permit. The following conditions must be met before the
City will issue the Public Improvement Permit.
A. Application for Public Improvement
The Owner/Developer shall submit a completed Application for Public Improvement
Permit (see two-sided application form in Appendix L). Construction cannot commence
until the City has approved the Public Improvement Permit. No application fee is required;
however, any outstanding invoices for City engineering services must be paid before the
permit is issued. See Section 4.10 Financial Responsibilities.
Public Improvement Design Standards Manual, 2023 Page 4-6
B. PEPI Plans Approved and Copied
The City will return the approved plans to the applicant. The applicant must generate 5
paper copies of the approved plan set and submit these to the City.
C. Land Use Applications Resolved
Approval criteria on all land use applications associated with the public improvements
shall be resolved consistent with Section 4.07.
D. Public Dedications
Public easements and/or rights-of-way must be dedicated over public facilities proposed
for public operations and maintenance. Dedication documents shall be submitted to the
City for review and approval prior to signing and recording. If the property is in the process
of being divided, the land partition or subdivision plat may serve as the dedicating
instrument. If land division is not recorded within a timely manner, separate dedication
documents will be required.
E. Maintenance Agreements
Agreements regarding operations and maintenance of stormwater facilities may be
required. Draft agreements shall be submitted to the City for review and approval prior
to signing and recording.
F. Second Public Notice consistent with Section 4.09
G. Financial Surety of performance and warranty consistent with Section 4.10
H. Contractor and Construction Schedule consistent with Section 4.12

consistent with the Standard Specifications. Refer to Section 2.07 for design standards.
Refer to Section 4.13, below, regarding temporary traffic controls.
J. Engineering Submittals for all other materials used consistent with the Standard
Specifications and Drawings.
K. Other Applicable Permits Obtained consistent with Section 4.11.
Public Improvement Design Standards Manual, 2023 Page 4-7
4.05 CITY ENGINEERING SERVICES
The City will review all construction plans and project documents for compliance with
applicable requirements; provide consultation with, and research for, the applicant, Project
Engineer, Owner and/or Developer; permit approved construction plans; inspect all
construction and perform acceptance testing; and provide other engineering services
necessary to complete the project work defined in the Engineering & Construction
Agreement.
The City will invoice the PEPI applicant (Owner/Developer) monthly for all costs incurred by
the City to complete the proposed public improvement project.
4.06 PRIVATE ENGINEERING SERVICES
In order to comply with applicable requirements, the Project Engineer’s contract with the
Owner/Developer should consider the following services:
1. Surveying sufficient to prepare construction plans, construction staking, and post-
construction monumentation;
2. Preparing construction drawings, specifications, and as-constructs with final field
measures and elevations in accordance with City standards; and,
3. Serving as the project liaison between the Owner/Developer, Contractor, subcontractors,
and the City.
4.07 CONCURRENT PLANNING APPLICATIONS
If the public improvements are associated with a development that has pending land use
application(s), PEPI plan approval and permit issuance are dependent on the following:
• If the land use application is a subdivision or partition, the Engineering and Construction
Agreement and improvement plans will not be accepted until the tentative plan has been
approved. Until the final plat application is submitted, only one review of the
improvement plans will occur. Construction plans will be approved when the construction
plans are compliant with the final plat. A copy of the final site plans must be provided and
attached for informational purposes to the construction drawings. Signed right-of-way
deeds and/or easement deeds may be required by the City in-lieu of the final plat
approval to allow construction during the dry season.
• If the land use application is a Site Review or Conditional Use Permit, concurrence from
the Planning Division is required prior to construction plan approval. Prior to approving
the construction plans, a copy of the approved final site plans must be provided so that
Public Improvement Design Standards Manual, 2023 Page 4-8
the site plans can be included for informational purposes to the construction drawings.
• If the land use application is a PUD, then final PUD approval is required prior to
construction plan approval. An approved site plan drawing must be submitted and
included for informational purposes with the approved construction drawings. However,
some initial, but limited, site preparation work may proceed if specifically authorized by
the Planning Division.
4.08 CONCURRENCES
Although the City will help facilitate plan-review coordination and resolution amongst
affected utility owners and City departments, the PEPI applicant (Owner/Developer) is
ultimately responsible for obtaining concurrence from the following:
A. City Staff
Before approving construction plans, the following City personnel must concur with
design and construction plans relevant to their respective regulations.
1. When the project involves a land division, Land Use Review/Survey staff must
confirm that the platting process is sufficiently advanced such that no unresolved
plat issue could influence the public improvement design.
2. Erosion Prevention staff must review and approve the Construction Site
Management Plan. If an Erosion Prevention permit is required, it must be issued
prior to the PEPI permit issuance.
3. The Urban Forester must review and approve street tree protection measures and
any street tree removals or critical root zone impacts.
4. The Planning Department staff shall confirm that PUD, Site Review, and
Conditional Use approvals have been issued, if applicable.
5. The Fire Marshal must review and approve emergency vehicle access.
6. Traffic Operations staff must review and approve street lights, signs, signals,
striping, and barricades.
B. Utility Companies
The Project Engineer shall route a copy of each plan to all utility companies for review,
concurrence with the design, and scheduling of utility work. The concurrences must
acknowledge review of the PEPI plan set for the following: any conflicts with existing
facilities; existing facilities that will be replaced, adjusted, or repaired with the project;
Public Improvement Design Standards Manual, 2023 Page 4-9
and any new facilities that will be constructed with the project. Copies of the signed
concurrences shall be submitted to the City Engineer prior to approving the
construction plans. The Project Engineer is responsible for resolving any conflicts and
verifying that conditions of concurrence apply to final plans. (See Appendix L for utility
contact information.)
4.09 PUBLIC NOTIFICATION REQUIREMENTS
These standards require two public notices during the PEPI permit process: one before plan
approval and another when the permit is issued. The first public notice informs adjacent
property owners about the project; the second public notice alerts owners and occupants
within 250 feet of the construction zone of the construction schedule and traffic control
measures. Public notification requirements are to be fulfilled by the Project Engineer, subject
to review and approval by the City Engineer.
Both notices shall include the following information:
1. Project description.
2. Vicinity map.
3. Statement about the public improvement project being privately engineered,
funded, and constructed.
4. Project name and number, as assigned by the City.
5. Name and phone numbers of the primary contacts at the City and for the
Developer to receive questions or concerns.
6. Mailing envelopes labeled “Construction Information Enclosed”
The first public notice shall be mailed to property owners abutting the subject property or
the construction zone, whichever is greater. The Project Engineer shall submit to the City a
copy of the letter, map, and mailing list with the second review. PEPI plans cannot be
approved until evidence of the first public notice has been supplied to the City. If all adjacent
lands are under the ownership of the applicant (Owner/Developer), then public notice may
be waived. Concurrent land use application notices may be considered as sufficient
notification for these purposes, depending on the timing and extent of such notice.
The second public notice shall be mailed to property owners and occupants within 250 feet
of the construction zone and shall also include the following:
1. Description of the construction activity
2. Copy of the Traffic Control Plan approved by the City
3. Construction schedule
4. Name of the Contractor, along with the name and phone number of the contact
person(s) for the construction company
Public Improvement Design Standards Manual, 2023 Page 4-10
Evidence of this second notification must be submitted to the City at the preconstruction
meeting.
4.10 FINANCIAL RESPONSIBILITIES
A. Project Billing
The City will invoice the Owner/Developer monthly for engineering services performed
(see Section 4.05 for a listing of City engineering services included in the fee). Professional
service fees are established and adjusted annually by an administrative order of the City
Manager; contact the Engineering Division at 541-682-5291 for a current administrative
order. Billing will continue until the as-construct plans, provided by the Project Engineer,
are accepted by the City. Unless other arrangements are made, invoices for engineering
services shall be fully paid prior to the following:
1. Approval of the construction plans
2. Issuance of a Permit for Public Improvements (Notice to Proceed)
3. Acceptance of completed work and release of the bond
B. Other Fees
1. As-construct and Warranty Inspection Fees
These are flat-fees charged upon issuance of the Public Improvement Permit.
These fees recover the costs of reviewing as-construct drawings and performing
warranty inspections after construction activities have been completed and the
project has been placed on warranty. Refer to the current administrative order for
the fee schedule.
2. Equivalent Assessment
Connection to a public wastewater, stormwater, or street system may require
payment of an equivalent assessment if the subject property was not previously
assessed, in accordance with Eugene Code Chapter 7.
C. Performance and Warranty Financial Guarantee
Pursuant to EC 7.145, before commencing construction of any public improvement, a
bond or financial guarantee is required, ensuring and guaranteeing to the City all of
the following:
1. The improvement shall in all ways comply with the plans and specifications
approved by the City Engineer;
2. The improvement will be installed using first-class material and in a first-class
professional manner under the direction of the City Engineer;
3. The improvement shall be free from defects or need of repair for a period of at
Public Improvement Design Standards Manual, 2023 Page 4-11
least one year from completion of the improvement; and
4. Payment of all fees charged in compliance with EC 7.130 for City engineering and
inspection activities (plan review, inspection, and project administration)
associated with the project.
The financial surety may be either a bond in the amount equal to the estimated cost
of construction or a financial guarantee approved by the City Engineer in the amount
equal to 125% of the estimated cost of improvement to secure the construction
permit and finance the construction of the improvements. If using a financial
guarantee in lieu of a bond, twenty-five percent of the construction cost, or $25,000,
whichever is more, shall be secured by the City prior to establishing the warranty
period and retained in place throughout the warranty permit.
The financial surety may be provided by the landowner, Contractor,
Owner/Developer, or other interested party; however, if the financial surety is
provided by someone other than the Owner/Developer, the surety to submit to the
City written confirmation that the surety understands the risks and responsibilities of
being the surety, i.e., an acknowledgement that the surety understands that that if
the work is not completed, the City may act on the financial guarantee to complete
the improvements.
In determining the value of the financial surety, construction cost shall be based on
either the Owner/Developer's contract for the work or the official Engineer's
Estimate, whichever is larger, and shall include all material and construction costs,
traffic control, mobilization, and erosion prevention costs. To facilitate City
verification of the construction costs, the Project Engineer shall submit either a copy
of the contract between the Owner/Developer and Contractor listing the cost of the
public improvements and a description of the associated work by unit price or lump
sum by infrastructure type, or a formal Engineer’s Estimate in a unit price format.
Construction costs shall be itemized into the following improvement categories:
transportation, wastewater, stormwater, and other. Transportation improvements
include pavement, sub-grade, concrete walks, street lights, curb and gutter, driveway
approach, and related transportation facilities within the right-of-way. Stormwater
improvements include manholes, curb inlets, catch basins, pipes, swales, and closed
or open conveyance and water quality facilities. Wastewater improvements include
pipes, tees, service lines, pump stations and related work. Other costs may include
off-street bike paths and street trees.
(See Appendix L for sample/standard Bond/Escrow Agreement forms)
Public Improvement Design Standards Manual, 2023 Page 4-12
4.11 OTHER PERMITS
The applicant (Owner/Developer) is responsible for obtaining all other permits necessary to
complete the survey, design, and construction work. Depending on the type of work to be
performed and existing conditions, one or more of the following permits may be required:
A. Erosion Prevention Permit
If the Contractor’s work will disturb one acre or more of land, or, regardless of the size of
the area impacted, if the work is located in a “sensitive area” (as defined by Administrative
Rule 6.645 and includes open systems to be constructed), an Erosion Prevention Permit
must be approved before PEPI permit issuance. If the work will disturb one or more acres
but less than five the construction activity will automatically be covered under a National
Pollutant Discharge Elimination System (NPDES) 1200-CN permit. An NPDES 1200-C
permit is required for work disturbing an area larger than five acres in size.
B. Floodplain Development Permit
A Floodplain Development Permit is required prior to any development occurring within
the Special Flood Hazard Area (SFHA). The SFHA includes Zones A, AE, AO and the
Floodway for our community on the adopted Flood Insurance Rate Map (FIRM). The FIRM
was created by the Federal Emergency Management Agency (FEMA) as part of the
National Flood Insurance Program. Development includes any man-made-change (e.g.,
building, filling, excavating, grading, paving, etc.) within the regulatory floodplain.
Floodplain Development Permits are obtained at the Permit and Information Center. See
Appendix B for permit requirements. SFHA must also be shown on the CSMP as noted in
Section 3.
C. Wetland Permit
If wetland indicators are present, such as wetland plants, hydric soils or saturated
conditions, the applicant shall submit a wetland delineation that has received
concurrence from Division of State Lands (DSL). If public improvements are shown within
wetlands, a fill permit is required prior to PEPI permit issuance. A Corps of Engineers
permit is required for disturbance of any jurisdictional wetland. A joint Corps of
Engineers/Division of State Lands #404 permit is required for excavation or embankment
of 50 cubic yards or more of material within "waters of the State." (Refer to DSL for
definition, regulations, and permit requirements at
http://oregonstatelands.us/DSL/WETLAND). Wetlands shall be delineated on the CSMP;
see Section 3 for plan requirements.
Public Improvement Design Standards Manual, 2023 Page 4-13
D. Railroad Permit
Any work crossing (above or below ground) or adjacent to railroad property requires a
permit from the affected railroad company.
E. Fill Permit
A PEPI permit does not authorize grading/fill activity on private property. It is the
applicant’s responsibility to verify and obtain all necessary grading/fill permits through
Building and Permit Services at the Permit Information Center before starting any
construction outside of the public-rights of-way and easements.
F. Tree Removal Permit
A Tree Removal Permit may be required for work near street trees or removal of a tree
on private property. Removal of more than 30 percent of the critical root zone of a street
tree constitutes a felling and requires a permit. Authorization for planned, unavoidable
street tree removal is typically approved through the PEPI permit. Unanticipated technical
fellings or removals requires a separate street tree removal permit and/or may be subject
to penalties as violations of Chapter 6.300. Replacement of a street tree or payment of its
appraised value is required under the PEPI, as determined by the Urban Forester. See
Appendix D for applicable regulations. Trees shall be delineated on the CSMP; refer to
Section 3 for plan requirements.
G. Electric Permit
An Electrical Permit is required from Building Permit Services at the Permit and
Information Center for all traffic signal and street illumination work. The electrical
Contractor is responsible for obtaining the permit after the construction plans are
approved.
4.12 CONTRACTOR AND CONSTRUCTION SCHEDULE
Contractor: The applicant (Owner/Developer) shall submit a copy of their contract with a
qualified Contractor. If the Contractor is not known by the City Engineer pre-qualification
screening may be required.
Construction Schedule in accordance with the Standard Specifications shall be submitted
before the construction permit is issued.
Public Improvement Design Standards Manual, 2023 Page 4-14
4.13 TRAFFIC CONTROL PLAN (TCP)
A. The Project Engineer or Contractor shall submit a TCP showing temporary traffic control
devices to be used during construction for City approval prior to the PEPI permit being issued.
Temporary traffic control devices and signing shall comply with the current edition of
Manual of Uniform Traffic Control Devices (MUTCD), ODOT’s Temporary Traffic Control
Handbook and Standard Specifications, and the “Accessibility Guidelines for Pedestrian
Facilities in the Public Right-of-Way” as published in 36 CFR Part 1190.
B. The TCP shall include a temporary pedestrian access route (TPAR) plan for construction
that requires the closure or detour of pedestrian routes. The TPAR shall comply with the
“Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way” as published in
36 CFR Part 1190 in addition to the publications referenced in section A. (above) for
temporary traffic control. To the extent a provision of any publication listed in section A.
conflicts with the “Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-
Way”, the “Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way” shall
control.
C. Existing traffic controls shall not be visually obstructed, damaged, or tampered with in
any manner unless approved as part of the traffic control plan.
4.14 CONSTRUCTION REQUIREMENTS
A. Pre-Construction Meeting
Following approval of the plans and issuance of the PEPI permit, the applicant shall
schedule a pre-construction meeting with City staff and an on-site inspection with Erosion
Prevention staff prior to beginning any construction activities.
B. Inspection
All work must be inspected by the City. Any work performed on the project without
inspection is considered unauthorized and may be subject to removal and/or replacement
at the Owner/Developer’s expense. The Public Works Inspector (City Inspector) is the
City’s representative on the project during construction of public facilities. The City
Inspector is available from 7:00 a.m. until 3:30 p.m., Monday through Friday, except
holidays, and may be available at other times with prior arrangement. The Developer or
Contractor shall notify the City Engineering Division 24 hours before the services of the
City Inspector will be required on the job. If insufficient notice is given, inspection services
may not be available and the Contractor or Developer will be required to delay work until
an Inspector is available. If the Developer’s Contractor elects to work extended hours,
weekends, or holidays, the Contractor must receive approval from the City Inspector in
advance. Inspection services are not guaranteed outside of normal weekday work hours.
The City will contract for outside inspection services with private or public labs or
Public Improvement Design Standards Manual, 2023 Page 4-15
consultants to provide inspection services not available by City staff, such as sampling, lab
services, and bridge inspection. The Owner/Developer will be charged for all costs
associated with inspection, such as outside services and the City Inspector’s time, which
includes overtime and travel time to and from the job site.
The Owner/Developer’s Contractor is responsible for quality control of materials and
workmanship per the Standard Specifications. The City Inspector is responsible for
verifying that all materials and workmanship comply with the plans and specifications.
The City Inspector will normally attempt to notify the Contractor of any deficiencies the
same day as the inspection is performed or the next business day, depending on when
the information is available, but is not obligated to do so.
The Project Engineer shall provide the Contractor copies of the approved plans and the
Contractor’s crews shall have copies of the approved plans with them at the project site
while they are performing work. It is not the City Inspector’s duty to warn or prevent the
Contractor from performing incorrect work as a result of the Contractor’s crew not
possessing copies of the plans at the project site or through their use of plans that are not
the approved set.
C. Design Changes
The Project Engineer will act as the project coordinator and shall submit any design
change requests to the City Engineer. The Contractor shall not make any change until
written approval is issued by the City Engineer.
D. Construction Staking
The Project Engineer shall stake the project for construction, including, but not limited to,
ADA ramps. Field marking shall include all normal point information, such as cut/fill,
offset, station, etc. A copy of cut/fill notes shall be submitted to the City Inspector.
4.15 POST-CONSTRUCTION REQUIREMENTS
A. Centerline Monumentation
Prior to project final acceptance by the City, the Owner/Developer shall complete street
centerline monumentation in accordance with ORS Chapters 92 and 209, unless a post-
monumentation deposit was previously accepted by the City as part of a subdivision plat.
A summary of minimum requirements are as follows.
1. Monuments must be set by a Licensed Land Surveyor and meet statutory
requirements of ORS Chapter 92 Subdivision and Partitions.
2. Monuments placed on street centerlines shall be per ORS 92 and 209.
Public Improvement Design Standards Manual, 2023 Page 4-16
3. Points required for street centerline monumentation are:
a. All street centerline intersections, and
b. Curve points:
1) Points of intersection of all tangent lines, where possible (P.I.'s),
2) Beginning points of all curves (P.C.),
3) Ends of all curves (P.T.), and
4) Points on semi-tangents of all curves where crossing street intersections
fall within a curve.
When monuments of record have been replaced or reestablished by reference
monumentation, a formal survey shall be filed with the Lane County Surveyor and a copy
provided to the City Surveyor.
B. As-Constructs
Within 30 days after receiving the inspection notes from the City Inspector, the Project
Engineer shall submit both a reproducible copy and an electronic version of the
completed as-construct drawings for the project. Changes noted during construction and
field measurements indicated on the inspection notes shall be included. See Section 5 for
as-construct requirements. Failure to submit as-construct drawings shall suspend review
of other work submitted by the responsible firm for the project until as-construct work is
completed.
C. Project Completion Notice (Beginning of Warranty Period)
When all work shown on the approved plans has been completed and has met the final
inspection criteria outlined in the specifications, the City Engineer shall send a letter to
the Project Engineer, with a copy to the Contractor and Owner/Developer, confirming
completion of public improvements for City maintenance and commencement of the
warranty period.
D. Project Acceptance (Release Performance Financial Surety)
After the City's warranty inspection has been completed, required repairs have been
completed by the Contractor, centerline and right-of-way monumentation has been set
and accepted, as-construct plans have been submitted to the City and accepted, and all
charges have been paid, the City will issue a Final Acceptance Letter. Copies of the Final
Acceptance Letter will be distributed to the Contractor, the Project Engineer, the City
Finance Division, and the owner/Developer's bonding company. At this time, the City
Engineer may authorize release of the financial surety. Service connections will not be
permitted until the public system has been accepted by the City.
Public Improvement Design Standards Manual, 2023 Page 4-17
4.16 FAILURE TO COMPLY WITH CITY STANDARDS AND PROCEDURES
In the event the Project Engineer fails to adhere to requirements and/or schedules listed
herein, the City Engineer may postpone review of other submitted work until the deficiencies
are corrected. Failure to complete as-construct work within the time requirements shall
postpone review of other work.

SECTION 5 – AS-CONSTRUCTS
5.00 INTRODUCTION
As-constructs (aka, as-builts, record-drawings) superimpose the approved design drawings
with what was actually constructed; any divergence between the two must be documented
as described below. As-constructs are required for all public improvement projects and must
adhere to the drafting standards in Section 3 of this manual and the following requirements.
5.01 SUBMITTAL REQUIREMENTS
A. Paper Copy
One reproducible (high-quality images, text and paper) copy of the as-constructs shall be
submitted.
B. Electronic Copy
The City requires Privately Engineered Public Improvement (PEPI) contractors to submit
electronic Computer-Aided Design (CAD) as-construct files with their final drawings. At a
minimum, the electronic CAD drawings must delineate control points, light poles, sewer
and storm system and curb lines. The CAD files must be provided in State Plane
coordinates, the layer naming convention must conform to those used by the City and the
CAD file type must be compatible with the City’s software.
The coordinates of the CAD file map features (e.g., storm lines) must be in Oregon State
Plane Coordinates 83/91 South Zone measured in international feet. The origin of the
coordinates shall be stated. Vertical datum shall be NAVD88 measured in US survey foot.
The benchmark used for the basis of elevations shall be stated. The horizontal and vertical
map features must be accurate to 0.10 foot.
The layer names in the PEPI CAD files must conform to those used by the City. The DVD
provided with the PIDS manual contains an AutoCAD City of Eugene As-Const
Template.dwg drawing file. This file contains all the standard layer names and may be
used as a template. Listed below are the standard City layer names, in parenthesis, for
the minimal delivery.
The electronic as-construct submittals will be on DVD and in AutoCAD DWG format.
Contact the City for information on the acceptable releases of AutoCAD. Other formats
may be considered if they can be imported into AutoCAD or ArcView. All revisions to the
original CAD drawings must be incorporated into the electronic submittal. All CAD files of
as-construct drawings must conform to the layering names provided in the drawing
template provided in the PIDS manual.

5.02 REVISIONS
All plan data shall be verified for accuracy. Revisions to the approved design drawings,
reflecting what was actually constructed, must be mapped accordingly. In some instances,
changes will require additional engineering analysis. More detailed instructions specific to
infrastructure type are provided below, but general expectations are as follows:
A. Strikethrough Requirement
Cross out original language or design (with a single line so it is still readable) and write in
new language. DO NOT ERASE THE OLD/CHANGED INFORMATION.
B. Record Requirements
Record and date all revisions on appropriate sheet(s). List revisions and change orders in
the title block, beginning at the bottom line and continue with subsequent entries
progressing toward the top line (not from top to bottom.) Letter the revision number in
a triangle.
If right-of-way and/or public easement dimensions/locations changed, then verify that
the dedication document was revised/replaced accordingly (i.e., new deed, legal
description, property owner signature, and recording at Lane County).
5.03 TITLE BLOCK ADDITIONS
Add the following information to the title block:
A. Inspector
Date stamp “INSPECTED BY” followed by the project City Inspector’s first initial and last
name (e.g., INSPECTED BY M. CAIRO).
Public Improvement Design Standards Manual, 2023 5 - 3
B. As-Constructor
Date stamp “AS CONSTRUCTED” and letter “FIRST INITIAL” and “LAST NAME” inspector.
C. Engineer
ENGINEER’S STAMP: The engineer who stamped the original drawings must also stamp
the as-construct drawings. In addition to the engineer’s stamp, all private jobs are
required to have been stamped approved by the City’s project manager in charge of
privately constructed projects.
D. Contract Number
Insert the contract number assigned by the City (e.g., 2014-0501).
5.04 STREET VERIFICATIONS
Correct or add data from the inspection notes. Verify the following paving information on the
as-construct drawings:
A. Stationing
Check beginning and ending paving stations for accuracy.
B. Excavation Type
If it changed, cross out old and write in new.
C. Pavement Type
If an alternate paving type was bid, cross out the non-applicable paving type.
D. Paving Width
If changed, cross out old and write in new.
E. Sidewalk Location
If dimensions changed, cross out old and write in new.
F. Curb Radius
If it changed from the design, cross out old curb radius value and write in new.
G. Curb Location
Check location relative to property line and/or centerline. If curb location changed, cross
out old and write in new dimensions.
Public Improvement Design Standards Manual, 2023 5 - 4
H. Curb Elevations
If curb elevations differ from design by more than 0.10 foot, cross out old and write in
new design data on drawings.
5.05 WASTEWATER VERIFICATIONS
Correct or add data from the inspection notes. Verify the following wastewater information
on the as-construct drawings:
A. Structure Numbers
All manholes and “phantoms” (a change in the angle of the pipe) on the plans and in the
profiles must be numbered, except for pipes less than eight inches in diameter or 25 feet
in length. When a manhole is added on an existing line (segment), two new segments are
created. Each segment needs a FROM and TO number. New numbers are provided by the
City’s as-construct monitor. Obtain existing numbers from the City’s wastewater index
maps. Add or cross out manholes and phantom numbers on the plans per the inspection
and final measurements.
B. Main Lines
Show the final measurements of all wastewater lines (from manhole to manhole). When
a segment continues from one drawing to the next, show the total length on both
drawings. Check against the inspection notes and video report and identify the video
report number. If there is more than a five-foot discrepancy, document the reason.
Check and correct the flow lines of all fixtures and ends of pipe in the profile. Cross out
old and write in new lines from final measurements. If the flow line from the final
measurement differs from the design by more than 0.10 foot or if the pipe size changed,
then obtain new wastewater design data from the Design Engineer and cross out old and
write in new design data on the drawings.
If pipe size, slope, or type changes, obtain new design data, cross out the old data and
write in the new. Show the top of the fixture elevation in the profile.
Revise any pipe hydraulic data as appropriate.
C. Service Lines
Show the tee location per the Inspector’s notes and video report. If they differ by more
than 3 feet, document why there is such a discrepancy. If there is no service line to a lot,
indicate why on the drawing. Specifically note if the depth of the service line is either
shallower than 4 feet or deeper than 6 feet.
Dimension service lines and tees using straight-line progression arrows from the nearest
Public Improvement Design Standards Manual, 2023 5 - 5
manhole and show distances. Check and correct the length and/or alignment of service
lines on the drawing. Cross out old footage and write in new from inspection notes.
5.06 STORMWATER VERIFICATIONS
Correct or add data from the inspection notes. Verify the following stormwater information
on the as-construct drawings:
A. Structure Numbers
All manholes, catch basins, taps, end of pipe segments, and phantoms on the plans and
in the profiles must be numbered, except for pipes less than 10 inches in diameter or 25
feet in length. New numbers are provided by the City’s as-construct monitor. Obtain
existing numbers from the City’s stormwater index maps.
Add or cross out manholes, catch basins, taps, end of pipe segments, and phantom
numbers on the plans per the inspection and final measurements. When a manhole is
added on an existing line (segment), two new segments are created. Each segment needs
a FROM and TO number. Use the line break symbol if necessary.
B. Main Lines
Show the final measurements of all stormwater lines (e.g., from manhole to manhole,
manhole to catch basin, and catch basin/manhole to end of pipe). When a segment
continues from one drawing to the next, show the total length on both drawings. Check
against the inspection notes and video report and identify the video report number. If
there is more than a five-foot discrepancy, document the reason.
Check and correct flow lines of all fixtures and ends of pipe in the profile. Cross out old
and write in new from final measurements. If the flow line from final measurement differs
from the design by more than 0.10 foot or if the pipe size changed, then obtain new
stormwater design data from the engineer and cross out old and write in new design data
on the drawings.
Show the elevation of both the top and the bottom of all stormwater structures in the
profile. Check and correct catch basin type (cross out old construction note and write in
new, and change drafting symbol). Revise any pipe hydraulic data as appropriate.
5.07 STREET LIGHTS
Correct or add data from the inspection notes. Verify the following street light information
on the as-construct drawings:
A. Pole Numbers
All street light poles need to be numbered on the street light plans. Numbers can be
Public Improvement Design Standards Manual, 2023 5 - 6
found in the inspection notes.
B. Pole Location
If the location of a pole changes, cross out the old location and write in the new location.
C. Junction Boxes and Conduit
Show final locations of all junction boxes and conduit.
5.08 TRAFFIC CONTROL DEVICES
Correct or add data from the inspection notes. Verify the following traffic control information
on the as-construct drawings:
A. Revisions
Revise plans with all corrections, including accurate location of supports, markings, and
other traffic control devices.
B. Notes
