This chapter contains standards and procedures for both public transportation facilities and public utilities. Transportation facilities include elements of the public right-of-way such as streets, sidewalks, bicycle lanes, street trees, and benches. Public utilities include water, sewer, and storm infrastructure. Collectively, transportation facilities and public utilities are referred to as "public facilities." Public facilities that are built as a requirement of this chapter shall be designed and constructed in accordance with the Public Works Standards.
The main focus of this chapter is to ensure the provision of safe, convenient, and adequate public transportation facilities consistent with the adopted City of Milwaukie Transportation System Plan (TSP). The TSP outlines the community's vision for transportation facilities, which, among other things, includes a desire for complete streets with a multimodal emphasis. This chapter implements that vision by addressing the need for Transportation facility improvements in a way that is consistent and equitable.
Provisions of this chapter coordinate with Title 12 Streets, Sidewalks, and Public Places, Chapter 13.28 Capital Improvements, Chapter 13.30 Reimbursement Districts, and Chapter 15.36 Public Works Standards. Any conflict between this chapter and another shall be resolved by administrative determination of the Engineering Director and Planning Director, as appropriate. Where the conditions imposed by any provision of this title are less restrictive than comparable conditions imposed by another provision of this title or any other ordinance, resolution, or regulation, the provision which is most restrictive shall govern. Unless specifically defined in Section 19.201, words or phrases used in this chapter are intended to be interpreted with the meaning they have in common usage to give this chapter its most reasonable application.
The purpose of Chapter 19.700 is to ensure that development, including redevelopment, provides public facilities that are safe, convenient, and adequate in rough proportion to their public facility impacts. The purposes of this chapter include the following:
(Ord. 2025 § 2, 2011)

A new dwelling unit.
2. 
Any increase in gross floor area.
3. 
Any projected increase in vehicle trips, as determined by the City Engineer.
Chapter 19.700 applies to single detached and duplex residential expansions as described below. The City has determined that the following requirements are roughly proportional to the impacts resulting from single detached and duplex residential expansions.
A. 
For expansions or conversions that increase the combined gross floor area of all structures (excluding nonhabitable accessory structures and garages) by 1,500 sq ft or more, all of Chapter 19.700 applies.
B. 
For expansions or conversions that increase the combined gross floor area of all structures (excluding nonhabitable accessory structures and garages) by at least 800 sq ft, but not more than 1,499 sq ft, right-of-way dedication may be required pursuant to the street design standards and guidelines contained in Subsection 19.708.2.
C. 
For expansions or conversions that increase the combined gross floor area of all structures (excluding nonhabitable accessory structures and garages) by less than 800 sq ft, none of Chapter 19.700 applies.
D. 
Single detached and duplex residential expansions shall provide adequate public utilities as determined by the City Engineer pursuant to Section 19.709.
E. 
Construction or expansion of garage and carport structures shall comply with the requirements of Chapter 12.16 Access Management. Existing nonconforming accesses may not go further out of conformance and shall be brought closer into conformance to the greatest extent possible.
A. 
Purpose
The purpose of the specific exemptions for some types of development in downtown Milwaukie is to encourage new uses in, and revitalization of, existing structures in downtown and to recognize that the transportation infrastructure in downtown is more complete than in other areas of the city.
B. 
Exemptions
1. 
For expansions or conversions that increase the combined gross floor area of all structures by 1,500 sq ft or less, frontage improvements are exempt, as described in the approval criterion of Subsection 19.703.3.B.
2. 
For changes of use, Chapter 19.700 applies. Frontage improvements for these increases in floor area are exempt, as described in Subsection 19.703.3.B.
C. 
Limitation to Exemptions
No more than one exempt increase in gross floor area, as described in Subsection 19.702.3.B.1, is allowed every 5 years. The 5-year period starts from the date the City issues an occupancy permit or final inspection for the expanded or converted development.
Chapter 19.700 applies to subsequent development that would exceed this limitation as follows.
1. 
Subsequent development is exempt per Subsection 19.702.3.B.1 if the total floor area of the initial development and subsequent development does not exceed 1,500 sq ft.
2. 
Subsequent development is not exempt per Subsection 19.702.3.B.1 if the total floor area of the initial development and subsequent development is greater than 1,500 sq ft. Review per Chapter 19.700 is based on all floor areas that are involved with the Development.
Chapter 19.700 does not apply to the following types of development in all zones:
A. 
Modifications to existing single detached and duplex residential structures that do not result in an increase in gross floor area.
B.

(Ord. 2025 § 2, 2011; Ord. 2051 § 2, 2012; Ord. 2059 § 2, 2013; Ord. 2140 § 2, 2017)
For all proposed development that requires a land use application and is subject to Chapter 19.700 per Section 19.702, the applicant shall schedule a preapplication conference with the City prior to submittal of the land use application. The Engineering Director may waive this requirement for proposals that are not complex.
For all proposed development that is subject to Chapter 19.700 per Section 19.702, one of the following types of applications is required.
A. 
Development Permit Application
If the proposed development does not require a land use application, compliance with Chapter 19.700 will be reviewed as part of the development permit application submittal.
B. 
Transportation Facilities Review (TFR) Land Use Application
If the proposed development triggers a transportation impact study (TIS) per Section 19.704, a TFR land use application shall be required. Compliance with Chapter 19.700 will be reviewed as part of the TFR application submittal and will be subject to a Type II review process as set forth in Section 19.1005. The TFR application shall be consolidated with, and processed concurrently with, any other required land use applications.
If the proposed development does not trigger a TIS per Section 19.704, but does require the submittal of other land use applications, compliance with Chapter 19.700 will be reviewed during the review of the other land use applications.
For all proposed development that is subject to Chapter 19.700 per Section 19.702, the required development permit and/or land use application shall demonstrate compliance with the following approval criteria at the time of submittal.
A. 
Procedures, Requirements, and Standards
Development and related public facility improvements shall comply with procedures, requirements, and standards of Chapter 19.700 and the Public Works Standards.
B. 
Transportation Facility Improvements
Development shall provide transportation improvements and mitigation at the time of development in rough proportion to the potential impacts of the development per Section 19.705 Rough Proportionality, except as allowed by Chapter 13.32 Fee in Lieu of Construction.
Development in downtown zones that is exempt per Subsection 19.702.3.B shall only be required to provide transportation improvements that are identified by a Transportation Impact Study as necessary to mitigate the development's transportation impacts. Such development is not required to provide on-site frontage improvements.
C. 
Safety and Functionality Standards
The City will not issue any development permits unless the proposed development complies with the City's basic safety and functionality standards, the purpose of which is to ensure that development does not occur in areas where the surrounding public facilities are inadequate. Upon submittal of a development permit application, an applicant shall demonstrate that the development property has or will have all of the following:
1. 
Adequate street drainage, as determined by the Engineering Director.
2. 
Safe access and clear vision at intersections, as determined by the Engineering Director.
3. 
Adequate public utilities, as determined by the Engineering Director.
4. 
Access onto a public street with the minimum paved widths as stated in Subsection 19.703.3.C.5 below.
5. 
Adequate frontage improvements as follows:
a. 
For local streets, a minimum paved width of 16 ft along the site's frontage.
b. 
For nonlocal streets, a minimum paved width of 20 ft along the site's frontage.
c. 
For all streets, a minimum horizontal right-of-way clearance of 20 ft along the site's frontage.
6. 
Compliance with Level of Service D for all intersections impacted by the development, except those on Oregon Highway 99E that shall be subject to the following:
a. 
Level of Service F for the first hour of the morning or evening 2-hour peak period.
b. 
Level of Service E for the second hour of the morning or evening 2-hour peak period.
There are 4 key determinations related to transportation facility improvements that occur during the processing of a development permit or land use application. These determinations are described below in the order in which they occur in the review process. They are also shown in Figure 19.703.4. In making these determinations, the City Engineer will take the goals and policies of the TSP into consideration and use the criteria and guidelines in this chapter.
A. 
Impact Evaluation
For development that is subject to Chapter 19.700 per Subsection 19.702.1, the City Engineer will determine whether the proposed development has impacts to the transportation system pursuant to Section 19.704. Pursuant to Subsection 19.704.1, the City Engineer will also determine whether a Transportation Impact Study (TIS) is required, or for smaller developments, if an Access Study or Transportation Memo is sufficient. If a TIS is required, a transportation facilities review land use application shall be submitted pursuant to Subsection 19.703.2.B.
For development that is subject to Chapter 19.700 per Subsection 19.702.2, the City has determined that there could be impacts to the transportation system if the proposed single detached residential expansion/conversion is greater than 800 sq ft.
B. 
Street Design
Given the City's existing development pattern, it is expected that most transportation facility improvements will involve existing streets and/or will serve infill development. To ensure that required improvements are safe and relate to existing street and Development conditions, the City Engineer will determine the most appropriate street design cross section using the standards and guidelines contained in Section 19.708 or in conformance to the Public Works Standards. On-site frontage improvements are not required for downtown development that is exempt per SubSection 19.702.3.B.
C. 
Proportional Improvements
When transportation facility improvements are required pursuant to this chapter, the City Engineer will conduct a proportionality analysis pursuant to Section 19.705 to determine the level of improvements that are roughly proportional to the level of potential impacts from the proposed development. Guidelines for conducting a proportionality analysis are contained in Subsection 19.705.2.
D. 
Fee in Lieu of Construction (FILOC)
If transportation facility improvements are required and determined to be proportional, the City will require construction of the improvements at the time of development. However, the applicant may request to pay a fee in lieu of constructing the required transportation facility improvements. The City Engineer will approve or deny such requests using the criteria for making FILOC determinations found in Chapter 13.32 Fee in Lieu of Construction.

A. 
Variances
Relief from any transportation facility improvement requirement in Section 19.708 may be granted through a variance process, which requires submittal and approval of a Variance land use application. Variance criteria and procedures are located in Section 19.911.
B. 
Appeals
Appeal of a land use decision is subject to the provisions of Chapter 19.1009. Appeal of a rough proportionality determination (Subsection 19.702.2 and Section 19.705) or street design standard determination (Subsection 19.708.2) not associated with a land use decision is subject to the provisions of Section 19.1006 Type III Review.
The Engineering Director will determine whether a proposed development has impacts on the transportation system by using existing transportation data. If the Engineering Director cannot properly evaluate a proposed development's impacts without a more Detailed study, a transportation impact study (TIS) will be required to evaluate the adequacy of the transportation system to serve the proposed development and determine proportionate mitigation of impacts. The TIS determination process and requirements are detailed below.
(Ord. 2025 § 2, 2011; Ord. 2218 § 2 (Exh. B), 2022)
A. 
Based on information provided by the applicant about the proposed development, the Engineering Director will determine when a TIS is required and will consider the following when making that determination.
1. 
Changes in land use designation, zoning designation, or development standard.
2. 
Changes in use or intensity of use.
3. 
Projected increase in trip generation.
4. 
Potential impacts to residential areas and local streets.
5. 
Potential impacts to priority pedestrian and bicycle routes, including, but not limited to, school routes and multimodal street improvements identified in the TSP.
6. 
Potential impacts to intersection level of service (LOS).
B. 
It is the responsibility of the applicant to provide enough detailed information for the Engineering Director to make a TIS determination.
C. 
A TIS determination is not a land use action and may not be appealed.
A. 
All transportation impact studies, including neighborhood through-trip and access studies, shall be prepared and certified by a registered Traffic or Civil Engineer in the State of Oregon.
B. 
Prior to TIS scope preparation and review, the applicant shall pay to the City the fees and deposits associated with TIS scope preparation and review in accordance with the adopted fee schedule. The City's costs associated with TIS scope preparation and review will be charged against the respective deposits. Additional funds may be required if actual costs exceed deposit amounts. Any unused deposit funds will be refunded to the applicant upon final billing.
C. 
The TIS shall be submitted with a transportation facilities review (TFR) land use application pursuant to Subsection 19.703.2.B and associated application materials pursuant to SubSection 19.703.3. The City will not accept a TFR application for processing if it does not include the required TIS. The City will not accept other associated land use applications for processing if they are not accompanied by the required TFR application.
D. 
The Engineering Director may require a TIS review conference with the applicant to discuss the information provided in the TIS. This conference would be in addition to the required preapplication conference pursuant to Subsection 19.703.1. If such a conference is required, the City will not accept the TFR application for processing until the conference has taken place. The applicant shall pay the TIS review conference fee at the time of conference scheduling, in accordance with the adopted fee schedule.
E. 
The City may attach conditions of approval to land use decisions as needed to satisfy the transportation facility requirements of Section 19.708 and to mitigate transportation impacts identified in the TIS.
A. 
TIS Scope
The Engineering Director shall determine the study area, study intersections, trip rates, traffic distribution, and required content of the TIS based on information provided by the applicant about the proposed development.
1. 
The study area will generally comprise an area within a ½-mile radius of the Development site. If the Engineering Director determines that development impacts may extend more than ½ mile from the development site, a larger study area may be required.
2. 
If notice to ODOT or Clackamas County is required pursuant to Section 19.707, the City will coordinate with these agencies to provide a comprehensive TIS scope.
B. 
TIS Content
A project-specific TIS checklist will be provided by the City once the Engineering Director has determined the TIS scope. A TIS shall include all of the following elements, unless waived by the Engineering Director.
1. 
Introduction and Summary
This section should include existing and projected trip generation including vehicular trips and mitigation of approved development not built to date; existing level and proposed level of service standard for City and County streets and volume to capacity for State roads; project build year and average growth in traffic between traffic count year and build year; summary of transportation operations; proposed mitigation(s); and traffic queuing and delays at study area intersections.
2. 
Existing Conditions
This section should include a study area description, including existing study intersection level of service.
3. 
Impacts
This section should include the proposed site plan, evaluation of the proposed site plan, and a project-related trip analysis. A figure showing the assumed future year roadway network (number and type of lanes at each intersection) should also be provided.
4. 
Mitigation
This section should include proposed site and areawide specific mitigation measures. Mitigation measures shall be roughly proportional to potential impacts pursuant to Section 19.705.
5. 
Appendix
This section should include traffic counts, capacity calculations, warrant analysis, and any information necessary to convey a complete understanding of the technical adequacy of the TIS.
C. 
TIS Methodology
The City will include the required TIS methodology with the TIS scope.
D. 
Neighborhood Through-Trip Study
Any nonresidential development projected to add more than 25 through-vehicles per day to an adjacent residential local street or neighborhood route will require assessment and mitigation of residential street impacts. Through-trips are defined as those to and from a proposed development that have neither an origin nor a destination in the neighborhood. The through-trip study shall include all of the following:
1. 
Existing number of through-trips per day on adjacent residential local streets or neighborhood routes.
2. 
Projected number of through-trips per day on adjacent residential local streets or neighborhood routes that will be added by the proposed development.
3. 
Traffic management strategies to mitigate for the impacts of projected through-trips consistent with Section 19.705 Rough Proportionality and Subsection 19.704.4 Mitigation.
A. 
Transportation impacts must be mitigated at the time of development when the TIS identifies an increase in demand for vehicular, pedestrian, bicycle, or transit transportation facilities within the study area. With phased developments, transportation impacts must be mitigated at the time that particular phase of development identified in the TIS creates the need for the improvements to occur.
B. 
The following measures may be used to meet mitigation requirements. Other mitigation measures may be suggested by the applicant or recommended by a state authority (e.g., ODOT) in circumstances where a state facility will be impacted by a proposed development. The City Engineer or other decision-making body, as identified in Chapter 19.1000, shall determine if the proposed mitigation measures are adequate.
1. 
On-and off-site improvements beyond required frontage improvements.
2. 
Development of a transportation demand management program.
3. 
Payment of a fee in lieu of construction.
4. 
Correction of off-site transportation deficiencies within the study area that are not substantially related to development impacts.
5. 
Construction of on-site facilities or facilities located within the right-of-way adjoining the development site that exceed minimum required standards and that have a transportation benefit to the public.
The purpose of this section is to ensure that required transportation facility improvements are roughly proportional to the potential impacts of the proposed development. The rough proportionality requirements of this section apply to both frontage and off-site, or nonfrontage, improvements. A rough proportionality determination may be appealed pursuant to Subsection 19.703.5.
The Engineering Director will conduct a proportionality analysis for any proposed Development that triggers transportation facility improvements per this chapter, with the exception of development subject to Subsection 19.702.2. The Engineering Director may conduct a proportionality analysis for development that triggers transportation facility improvements per Subsection 19.702.2.
When conducting a proportionality analysis for frontage improvements, the Engineering Director will not consider prior use for the portion of the proposed development that involves new construction. The Engineering Director will, however, consider any benefits that are estimated to accrue to the development property as a result of any required transportation facility improvements.
The following general provisions apply whenever a proportionality analysis is conducted.
(Ord. 2025 § 2, 2011)
Mitigation of impacts, due to increased demand for transportation facilities associated with the proposed development, shall be provided in rough proportion to the transportation impacts of the proposed development. When a TIS is required, potential impacts will be determined in accordance with Section 19.704. When no TIS is required, potential impacts will be determined by the Engineering Director.
The following shall be considered when determining proportional improvements:
A. 
Condition and capacity of existing facilities within the impact area in relation to City standards. The impact area is generally defined as the area within a 1/2-mile radius of the proposed Development. If a TIS is required pursuant to Section 19.704, the impact area is the TIS study area.
B. 
Existing vehicle, bicycle, pedestrian, and transit use within the impact area.
C. 
The effect of increased demand associated with the proposed development on transportation facilities and on other approved, but not yet constructed, development projects within the impact area.
D. 
The most recent use when a change in use is proposed that does not involve new Construction.
E. 
Applicable TSP goals, policies, and plans.
F. 
Whether any route affected by increased transportation demand within the impact area is listed in any City program including, but not limited to, school trip safety, neighborhood traffic management, capital improvement, and system development improvement.
G. 
Accident history within the impact area.
H. 
Potential increased safety risks to transportation facility users, including pedestrians and cyclists.
I. 
Potential benefit the development property will receive as a result of the construction of any required transportation facility improvements.
J. 
Other considerations as may be identified in the review process.
(Ord. 2025 § 2, 2011; Ord. 2112 § 2 (Exh. B), 2015)
In addition to the general notice provisions set forth in Chapter 19.1000 for land use applications, the City shall provide notice of applications that are subject to Chapter 19.700 to the following agencies:
A. 
Oregon Department of Transportation (ODOT): If the proposed development generates more than 100 vehicle trips per day, is within 200 ft of a State highway, or is within 1,320 ft of a State highway interchange ramp.
B. 
ODOT Rail Division: If the proposed development is within 300 ft of a public railroad crossing or if a modification is proposed to an existing public railroad crossing. Private crossing improvements are subject to review and licensing by the private rail service provider.
C. 
Metro and Clackamas County: If the proposed development is within 200 ft of a designated arterial or collector roadway, as identified in Figure 8-1 of the TSP.
D. 
Metro: If the proposed development is within 200 ft of a designated regional multiuse trail, as identified in the Regional Transportation Plan.
E. 
TriMet: If the proposed development (excluding single-family development on an existing lot) is within 200 ft of an existing or proposed transit route as identified on the current TriMet service map and Figure 7-3 of the TSP.
The City shall coordinate application review and land use findings and conditions, if any, with the agencies listed above. The City shall include the deadline for review comments in its notice. Agencies shall indicate in their comments if additional public facility permits or approvals are required through their agency separate from City permits and approvals.
This section contains the City's requirements and standards for improvements to public streets, including pedestrian, bicycle, and transit facilities. For ease of reading, the more common term "street" is used more frequently than the more technical terms "public right-of-way" or "right-of-way." As used in this section, however, all three terms have the same meaning.
The City recognizes the importance of balancing the need for improved transportation facilities with the need to ensure that required improvements are fair and proportional. The City also acknowledges the value in providing street design standards that are both objective and flexible. Objective standards allow for consistency of design and provide some measure of certainty for developers and property owners. Flexibility, on the other hand, gives the City the ability to design streets that are safe and that respond to existing street and development conditions in a way that preserves neighborhood character.
The City's street design standards are based on the street classification system described in the TSP. Figure 8-1 of the TSP identifies the functional street classification for every street in the City and Figure 10-1 identifies the type and size of street elements that may be appropriate for any given street based on its classification.
(Ord. 2025 § 2, 2011; Ord. 2051 § 2, 2012; Ord. 2059 § 2, 2013; Ord. 2106 § 2 (Exh. F), 2015; Ord. 2110 § 2 (Exh. G), 2015; Ord. 2112 § 2 (Exh. B), 2015; Ord. 2168 § 2, 2019; Ord. 2218 § 2 (Exh. B), 2022)
A. 
Access Management
All development subject to Chapter 19.700 shall comply with access management standards contained in Chapter 12.16.
B. 
Clear Vision
All development subject to Chapter 19.700 shall comply with clear vision standards contained in Chapter 12.24.
C. 
Development in Downtown Zones
Street design standards and right-of-way dedication for the downtown zones are subject to the requirements of the Milwaukie Public Works Standards, which implement the streetscape design of the Milwaukie Downtown and Riverfront Plan: Public Area Requirements (PAR). Unless specifically stated otherwise, the standards in Section 19.708 do not apply to development located in the downtown zones or on street sections shown in the PAR per Subsection 19.304.6.
D. 
Development in Non-Downtown Zones
Development in a non-downtown zone that has frontage on a street section shown in the PAR is subject to the requirements of the Milwaukie Public Works Standards, which implements the street design standards and right-of-way dedication requirements contained in the PAR for that street frontage. The following general provisions apply only to street frontages that are not shown in the PAR and for Development that is not in any of the downtown zones listed in Subsection 19.708.1.C above:
1. 
Streets shall be designed and improved in accordance with the standards of this chapter and the Public Works Standards. ODOT facilities shall be designed consistent with State and federal standards. County facilities shall be designed consistent with County standards.
2. 
Streets shall be designed according to their functional classification per Figure 8-3b of the TSP.
3. 
Street right-of-way shall be dedicated to the public for street purposes in accordance with Subsection 19.708.2. Right-of-way shall be dedicated at the corners of street Intersections to accommodate the required turning radii and transportation facilities in accordance with Section 19.708 and the Public Works Standards. Additional dedication may be required at intersections for improvements identified by the TSP or a required transportation impact study.
4. 
The City shall not approve any development permits for a proposed development unless it has frontage or approved access to a public street.
5. 
Off-site street improvements shall only be required to ensure adequate access to the proposed development and to mitigate for off-site impacts of the proposed development.
6. 
The following provisions apply to all new public streets and extensions to existing public streets.
a. 
All new streets shall be dedicated and improved in accordance with this chapter.
b. 
Dedication and construction of a half-street is generally not acceptable. However, a half-street may be approved where it is essential to allow reasonable development of a property and when the review authority finds that it will be possible for the property adjoining the half-street to dedicate and improve the remainder of the street when it develops. The minimum paved roadway width for a half-street shall be the minimum width necessary to accommodate 2 travel lanes pursuant to Subsection 19.708.2.
7. 
Traffic calming may be required for existing or new streets. Traffic calming devices shall be designed in accordance with the Public Works Standards or with the approval of the Engineering Director.
8. 
Railroad Crossings
Where anticipated development impacts trigger a need to install or improve a railroad crossing, the cost for such improvements may be a condition of development approval.
9. 
Street Signs
The City shall install all street signs, relative to traffic control and street names, as specified by the Engineering Director. The applicant shall reimburse the City for the cost of all such signs installed by the City.
10. 
Streetlights
The location of streetlights shall be noted on approved development plans. Streetlights shall be installed in accordance with the Public Works Standards or with the approval of the Engineering Director.
E. 
Street Layout and Connectivity
1. 
The length, width, and shape of blocks shall take lot size standards, access and circulation needs, traffic safety, and topographic limitations into consideration.
2. 
The street network shall be generally rectilinear but may vary due to topography or other natural conditions.
3. 
Streets shall be extended to the boundary lines of the developing property where necessary to give access to or allow for future development of adjoining properties.
a. 
Temporary turnarounds shall be constructed for street stubs in excess of 150 ft in length. Drainage facilities shall be constructed to properly manage stormwater runoff from temporary turnarounds.
b. 
Street stubs to adjoining properties shall not be considered turnarounds, unless required and designed as turnarounds, since they are intended to continue as through streets when adjoining properties develop.
c. 
Reserve strips may be required in order to ensure the eventual continuation or completion of a street.
4. 
Permanent turnarounds shall only be provided when no opportunity exists for creating a through street connection.

Table 19.708.2 contains the street design elements and dimensional standards for street cross sections by functional classification. Dimensions are shown as ranges to allow for flexibility in developing the most appropriate cross section for a given street or portion of street based on existing conditions and the surrounding development pattern. The additional street design standards in Subsection 19.708.2.A augment the dimensional standards contained in Table 19.708.2. The Engineering Director will rely on Table 19.708.2 and Subsection 19.708.2.A to determine the full-width cross section for a specific street segment based on functional classification. The full-width cross section is the sum total of the widest dimension of all individual street elements. If the Engineering Director determines that a full-width cross section is appropriate and feasible, a full-width cross Section will be required. If the Engineering Director determines that a full-width cross section is not appropriate or feasible, the Engineering Director will modify the full-width cross section requirement using the guidelines provided in Subsection 19.708.2.B. Standards for design speed, horizontal/vertical curves, grades, and curb return radii are specified in the Public Works Standards.
