A. 
Purpose. The purpose of this chapter is to provide planning and design standards for public and private transportation facilities and utilities. Streets are the most common public spaces, touching virtually every parcel of land. Therefore, one of the primary purposes of this chapter is to provide standards for attractive and safe streets that can accommodate vehicle traffic from planned growth, and provide a range of transportation options, including options for driving, walking, bus transit, and bicycling. This chapter implements portions of the City's Transportation System Plan.
Important Cross-Reference to Other Standards. The City requires that public and private streets provide direct and convenient access, including regular intersections. Chapter 16.120, Access and Circulation, provides standards for intersections and blocks, and requires pedestrian access ways to break up long blocks.
B. 
When Standards Apply. Unless otherwise provided, the standard specifications for construction, reconstruction or repair of transportation facilities (public or private), utilities and other public improvements within the City shall occur in accordance with the standards of this chapter. No development may occur unless the public (or private, in some instances) facilities related to development comply with the public facility requirements established in this chapter.
C. 
Standard Specifications. The City shall establish standard construction specifications consistent with the design standards of this chapter and application of engineering principles. They are incorporated in this Code by reference.
D. 
Conditions of Development Approval. No development may occur unless required public facilities are in place or guaranteed, in conformance with the provisions of this Code. Improvements required as a condition of development approval, when not voluntarily accepted by the applicant, shall be roughly proportional to the impact of development. Findings in the development approval shall indicate how the required improvements are roughly proportional to the impact.
A. 
Development Standards. No development shall occur unless the lot or parcel abuts a public or private street, other than an alley, for at least 25 feet and is in conformance with the provisions of Chapter 16.120, Access and Circulation, and the following standards are met:
1. 
Streets within or adjacent to a development shall be improved in accordance with the Comprehensive Plan, Transportation System Plan, and the provisions of this chapter;
2. 
Development of new streets (public or private), and additional street width or improvements planned as a portion of an existing street, shall be improved in accordance with this section, and public streets shall be dedicated to the applicable City, County or State jurisdiction;
3. 
New streets and drives connected to a City collector or arterial street shall be paved; and
4. 
The City may accept a future improvement guarantee [e.g., owner agrees not to remonstrate (object) against the formation of a local improvement district in the future] in lieu of street improvements if one or more of the following conditions exist:
a. 
A partial improvement may create a potential safety hazard to motorists or pedestrians,
b. 
Due to the developed condition of adjacent properties it is unlikely that street improvements would be extended in the foreseeable future and the improvement associated with the project under review does not, by itself, provide increased street safety or capacity, or improved pedestrian circulation,
c. 
The improvement would be in conflict with an adopted capital improvement plan, or
d. 
The improvement is associated with an approved land partition on property zoned residential and the proposed land partition does not create any new streets.
B. 
Variances. Variances to the transportation design standards in this section may be granted by means of a Class 2 variance, as governed by Chapter 16.272, Variances. A variance may be granted under this provision only if a required improvement is not feasible due to topographic constraints or constraints posed by sensitive lands (see Chapter 16.156).
C. 
Creation of Rights-of-Way for Streets and Related Purposes. Streets shall be created through the approval and recording of a final subdivision or partition plat; except the City may approve the creation of a street by acceptance of a deed, provided that the street is deemed essential by the City Commission for the purpose of implementing the Transportation System Plan, and the deeded right-of-way conforms to the standards of this Code. All deeds of dedication shall be in a form prescribed by the City Attorney and shall name "the public," as grantee.
D. 
Creation of Access Easements. The City may approve an access easement established by deed when the easement is necessary to provide for access and circulation in conformance with Chapter 16.120, Access and Circulation. Access easements shall be created and maintained in accordance with the Uniform Fire Code, as amended.
E. 
Street Location, Width and Grade. Except as noted below, the location, width and grade of all streets shall conform to the Transportation System Plan and Comprehensive Plan, as applicable; and an approved street plan or subdivision plat. Street location, width and grade shall be determined in relation to existing and planned streets, topographic conditions, public convenience and safety, and in appropriate relation to the proposed use of the land to be served by such streets:
1. 
Street grades shall be approved by the City-appointed engineer in accordance with the design standards in subsection N of this section; and
2. 
Where the location of a street is not shown in an existing street plan (see subsection H of this section), the location of streets in a development shall either:
a. 
Provide for the continuation and connection of existing streets in the surrounding areas, conforming to the street standards of this chapter, or
b. 
Conform to a street plan adopted by the City, if it is impractical to connect with existing street patterns because of particular topographical or other existing conditions of the land. Such a plan shall be based on the type of land use to be served, the volume of traffic, the capacity of adjoining streets and the need for public convenience and safety.
F. 
Minimum Rights-of-Way and Street Sections. Street rights-of-way and improvements shall conform to the design standards in Table 16.136.010. A variance shall be required in accordance with Chapter 16.272 of this Code to vary the standards in Table 16.136.010. Where a range of width is indicated, the width shall be determined by the decision-making authority based upon the following factors:
1. 
Street classification in the Transportation System Plan or Comprehensive Plan;
2. 
Anticipated traffic generation;
3. 
On-street parking needs;
4. 
Sidewalk and bikeway requirements based on anticipated level of use;
5. 
Requirements for placement of utilities;
6. 
Street lighting;
7. 
Street tree location, as provided for in Chapter 16.124;
8. 
Protection of significant vegetation and wetland and riparian areas, as provided for in Chapters 16.124 and 16.156;
9. 
Safety and comfort for motorists, bicyclists, and pedestrians;
10. 
Street furnishings (e.g., benches, lighting, bus shelters, etc.), when provided;
11. 
Access needs for emergency vehicles; and
12. 
Transition between different street widths (i.e., existing streets and new streets), as applicable.

Notes:
1
Width if on-street parking is constructed in place of bike lanes. The travel lane width shall function as a shared roadway and accommodate bikes. On-street parking is not permitted where posted speeds are greater than 35 mph.
2
The standard design should be provided where feasible. In constrained areas where providing the standard widths are not practical, alternative minimum design requirements may be applied with approval of the City Engineer.
3
Median/flex lane and planting strips are optional depending on surrounding land use and available right-of-way.
4
Parking on residential neighborhood streets is allowed and may be allowed on one side only in constrained areas or where approved by the City Engineer, resulting in a curb-to-curb width of 28 feet and overall right-of-way width of 48 feet.
5
Shared-use path requires 2 foot gravel shoulder and 10 foot minimum vertical clearance. If a shared-used path is put in place of a sidewalk and bike lane a 1 foot to 2 foot paved shoulder and a 5 foot planter strip is required between the path and the travel lane.
6
Existing streets that require reconstruction or additional improvements such as sidewalks can be built to a 32 foot standard.
REFER TO FIGURES 9 - 14 OF THE TSP FOR CROSS SECTION VIEWS OF ALL STREET TYPES.
G. 
Traffic Signals. Traffic signals shall be required with development when traffic signal warrants are met, in conformance with the Highway Capacity Manual, and Manual of Uniform Traffic Control Devices. The location of traffic signals shall be noted on approved street plans. Where a proposed street intersection will result in an immediate need for a traffic signal, a signal meeting approved specifications shall be installed. The developer's cost and the timing of improvements shall be included as a condition of development approval. Traffic signals on roads under state jurisdiction shall be determined by the Oregon Department of Transportation.
H. 
Future Street Plan and Extension of Streets.
1. 
A future street plan shall be filed by the applicant in conjunction with an application for a subdivision in order to facilitate orderly development of the street system. The plan shall show the pattern of existing and proposed future streets from the boundaries of the proposed land division and shall include other parcels within 500 feet surrounding and adjacent to the proposed land division. The street plan is not binding; rather it is intended to show potential future street extensions with future development.
2. 
Streets shall be extended to the boundary lines of the parcel or tract to be developed, when the Community Development Director or Planning Commission determines that the extension is necessary to give street access to, or permit a satisfactory future division of, adjoining land. The point where the streets temporarily end shall conform to subparagraphs a through c of this paragraph:
a. 
These extended streets or street stubs to adjoining properties are not considered to be cul-de-sacs since they are intended to continue as through streets when the adjoining property is developed.
b. 
A barricade (e.g., fence, bollards, boulders or similar vehicle barrier) shall be constructed at the end of the street by the subdivider and shall not be removed until authorized by the City or other applicable agency with jurisdiction over the street. The cost of the barricade shall be included in the street construction cost.
c. 
Temporary turnarounds (e.g., hammerhead or bulb-shaped configuration) may be constructed for stub streets over 150 feet in length for a time period of up to two years. The developer shall guarantee conversion of the temporary hammerhead into a cul-de-sac that meets the standards of this Code by posting a performance bond that guarantees the required improvement within the time specified.
I. 
Street Alignment and Connections.
1. 
Staggering of streets making "T" intersections at collectors and arterials shall not be designed so that jogs of less than 300 feet on such streets are created, as measured from the centerline of the street.
2. 
Spacing between local street intersections shall have a minimum separation of 125 feet, except where more closely spaced intersections are designed to provide an open space, pocket park, common area or similar neighborhood amenity. This standard applies to four-way and three-way (off-set) intersections.
3. 
All local and collector streets which abut a development site shall be extended within the site to provide through circulation unless prevented by environmental or topographical constraints, existing development patterns or compliance with other standards in this Code. This exception applies when it is not possible to redesign or reconfigure the street pattern to provide required extensions. Land is considered topographically constrained if the slope is greater than 15% for a distance of 250 feet or more. In the case of environmental or topographical constraints, the mere presence of a constraint is not sufficient to show that a street connection is not possible. The applicant must show why the environmental or topographic constraint precludes some reasonable street connection.
4. 
Proposed streets or street extensions shall be located to provide direct access to existing or planned commercial services and other neighborhood facilities, such as schools, shopping areas and parks.
5. 
In order to promote efficient vehicular and pedestrian circulation throughout the City, the design of subdivisions and alignment of new streets shall conform to the following standards in Chapter 16.120, Access and Circulation: The maximum block length shall not exceed 1,000 feet between street corner lines unless it is adjacent to an arterial street or unless the topography or the location of adjoining streets justifies an exception. The maximum length of blocks along an arterial is 1,800 feet. A block shall have sufficient width to provide for two tiers of building sites unless topography or location of adjoining streets justifies an exception.
Exceptions to the above standards may be granted when an accessway is provided at or near mid- block, in conformance with the provisions of Section 16.120.030.
J. 
Sidewalks, Planter Strips, Bicycle Lanes. Sidewalks, planter strips, and bicycle lanes shall be installed in conformance with the standards in Table 16.136.010, applicable provisions of the Transportation System Plan, the Comprehensive Plan, and adopted street plans. Sidewalks are required on both sides of all streets (including streets inside easements), except for alley ways and walking paths. Maintenance of sidewalks, curbs, and planter strips is the continuing obligation of the adjacent property owner.
1. 
Fee in Lieu Option. An applicant may request or the City may require the applicant to pay a fee in lieu of constructing sidewalks and frontage improvements to be approved by the City Public Works Director or designee.
a. 
A fee in lieu may be approved given conditions, including, but not limited to, the following:
i. 
There is no existing or planned sidewalk network in the area.
ii. 
There is a planned sidewalk or multi-use pathway in the vicinity of the site, or an existing multi-use pathway stubbing into the site, that would provide better pedestrian connectivity.
iii. 
When physical improvements are present along an existing or proposed street that would prevent reasonable installation.
iv. 
When sidewalks and other frontage improvements would be located on land with cross slopes greater than nine percent, or other conditions that would create a potential hazard.
v. 
Other situations unique to the site.
b. 
The fee shall be not less than 125% of the cost to perform the work, as determined by the City Public Works Director or designee, based on the applicable City standards in effect at the time of application; or the City Public Works Director or designee may require the applicant's engineer to provide a cost estimate, subject to review and approval by the city, to determine the cost to perform the work. The fee shall be paid prior to plat recording or issuance of a building or development permit.
c. 
All fees paid shall be used for construction of a sidewalk and/or other related frontage improvements or multi-use pathway, or repair and maintenance of an existing sidewalk and/or related frontage improvements or pathway within the City of Warrenton.
K. 
Intersection Angles. Streets shall be laid out so as to intersect at an angle as near to a right angle as practicable, except where topography requires a lesser angle or where a reduced angle is necessary to provide an open space, pocket park, common area or similar neighborhood amenity. In addition, the following standards shall apply:
1. 
Streets shall have at least 25 feet of tangent adjacent to the right-of-way intersection unless topography requires a lesser distance;
2. 
Intersections which are not at right angles shall have a minimum corner radius of 20 feet along the right-of-way lines of the acute angle; and
3. 
Right-of-way lines at intersection with arterial streets shall have a corner radius of not less than 20 feet.
L. 
Existing Rights-of-Way. Whenever existing rights-of-way adjacent to or within a tract are of less than standard width, additional rights-of-way shall be provided at the time of subdivision or development, subject to the provisions of this chapter.
M. 
Cul-de-Sacs. A dead-end street shall be no more than 200 feet long, shall not provide access to greater than 18 dwelling units, and shall only be used when environmental or topographical constraints, existing development patterns, or compliance with other standards in this Code preclude street extension and through circulation.
1. 
All cul-de-sacs shall terminate with a circular turnaround. Circular turnarounds shall have a radius of no less than 40 feet from center to edge of pavement except that turnarounds that contain a landscaped island or parking bay in their center shall have a minimum radius of 45 feet. When an island or parking bay is provided, there shall be a fire apparatus lane of at least 20 feet in width; and
2. 
The length of the cul-de-sac shall be measured along the centerline of the roadway from the near side of the intersecting street to the farthest point of the cul-de-sac.
See Section 16.120.020 for fire access and parking area turnaround requirements based on Uniform Fire Code standards, as amended.
N. 
Grades and Curves. Grades shall not exceed 10% on arterials, 12% on collector streets, or 12% on any other street (except that local or residential access streets may have segments with grades up to 15% for distances of no greater than 250 feet), and:
1. 
Centerline curve radii shall not be less than 700 feet on arterials, 500 feet on major collectors, 350 feet on minor collectors, or 100 feet on other streets; and
2. 
Streets intersecting with a minor collector or greater functional classification street, or streets intended to be posted with a stop sign or signalization, shall provide a landing averaging five percent or less. Landings are that portion of the street within 20 feet of the edge of the intersecting street at full improvement.
O. 
Curbs, Curb Cuts, Ramps, and Driveway Approaches. Concrete curbs, curb cuts, wheelchair, bicycle ramps and driveway approaches shall be constructed in accordance with standards specified in Chapter 16.120, Access and Circulation, and City construction standards.
P. 
Streets Adjacent to Railroad Right-of-Way. Wherever the proposed development contains or is adjacent to a railroad right-of-way, a street approximately parallel to and on each side of such right-of-way at a distance suitable for the appropriate use of the land shall be created. New railroad crossings and modifications to existing crossings are subject to review and approval by Oregon Department of Transportation.
Q. 
Development Adjoining Arterial Streets. Where a development adjoins or is crossed by an existing or proposed arterial street, the development design shall separate residential access and through traffic, and shall minimize traffic conflicts. The design shall include one or more of the following:
1. 
A parallel access street along the arterial with a landscape buffer separating the two streets;
2. 
Deep lots abutting the arterial or major collector to provide adequate buffering with frontage along another street. Double-frontage lots shall conform to the buffering standards in Chapter 16.164;
3. 
Screen planting at the rear or side property line to be contained in a non-access reservation (e.g., public easement or tract) along the arterial; or
4. 
Other treatment suitable to meet the objectives of this subsection;
5. 
If a lot has access to two streets with different classifications, primary access shall be from the lower classification street, in conformance with Section 16.120.020.
R. 
Alleys, Public or Private. Alleys shall conform to the standards in Table 16.136.010. While alley intersections and sharp changes in alignment shall be avoided, the corners of necessary alley intersections shall have a radius of not less than 12 feet.
S. 
Private Streets. Private streets shall not be used to avoid connections with public streets. Gated communities (i.e., where a gate limits access to a development from a public street) are prohibited. Design standards for private streets are the same as design standards for public streets and shall conform to the provisions of Table 16.136.010.
T. 
Street Names. Street naming and numbering in the City of Warrenton (and Hammond) shall follow the uniform system of the City's addressing ordinance (Ord. No. 359-A). Street names, signs and numbers shall conform to the City's addressing ordinance.
U. 
Survey Monuments. Upon completion of a street improvement and prior to acceptance by the City, it shall be the responsibility of the developer's registered professional land surveyor to provide certification to the City that all boundary and interior monuments shall be reestablished and protected.
V. 
Street Signs. The City, county or state with jurisdiction shall install all signs for traffic control and street names. The cost of signs required for new development shall be the responsibility of the developer. Street name signs shall be installed at all street intersections. Stop signs and other signs may be required.
W. 
Mail Boxes. Plans for mail boxes to be used shall be approved by the United States Postal Service.
X. 
Street Light Standards. Street lights shall be installed in accordance with City standards.

(Ord. 1216-A § 1, 2018; Ord. 1225 § 7, 2019; Ord. 1232 § 1, 2019)
A. 
Dedication Requirements.
1. 
Where a proposed park, playground or other public use shown in a plan adopted by the City is located in whole or in part in a subdivision, the City may require the dedication or reservation of this area on the final plat for the subdivision.
2. 
If determined by the Planning Commission to be in the public interest in accordance with adopted Comprehensive Plan policies, and where an adopted plan of the City does not indicate proposed public use areas, the City may require the dedication or reservation of areas within the subdivision of a character, extent and location suitable for the development of parks and other public uses.
3. 
All required dedications of public use areas shall conform to Section 16.136.010(D) (Conditions of Development Approval).
B. 
Acquisition by Public Agency. If the developer is required to reserve land area for a park, playground, or other public use, the land shall be acquired by the appropriate public agency within 12 months following final plat approval, at a price agreed upon prior to approval of the plat, or the reservation shall be released to the property owner.
C. 
System Development Charge Credit. Dedication of land to the City for public use areas shall be eligible as a credit toward any required system development charge for parks.
A. 
Sewers and Water Mains Required. Sanitary sewers and water mains shall be installed to serve each new development and to connect developments to existing mains in accordance with the City's construction specifications and the applicable Comprehensive Plan policies. Where City sanitary sewers are not physically or legally available to service the site, the applicant must demonstrate provisions for a suitable onsite disposal system permitted by DEQ prior to issuance of City permits. All development within a growth management (GM) zone, as identified on the official Warrenton Zoning Map, shall comply with the growth management zone standards of Chapter 16.112.
B. 
Sewer and Water Plan Approval. Development permits for sewer and water improvements shall not be issued until the City-appointed engineer has approved all sanitary sewer and water plans in conformance with City standards.
C. 
Over-sizing. Proposed improvements to the City sewer and water systems shall be sized to accommodate additional development within the area as projected by the Comprehensive Plan, Water System Master Plan, and/or Sanitary Sewer Master Plan. The developer shall be entitled to system development charge credits for the over-sizing.
D. 
Permits Denied. Development permits may be restricted by the City where a deficiency exists in the existing water or sewer system which cannot be rectified by the development and which if not rectified will result in a threat to public health or safety, surcharging of existing mains, or violations of state or federal standards pertaining to operation of domestic water and sewerage treatment systems. Building moratoriums shall conform to the criteria and procedures contained in ORS 197.505.
A. 
General Provisions. The City shall issue a development permit only where adequate provisions for stormwater and floodwater runoff have been made in conformance with Chapter 16.140, Stormwater and Surface Water Management.
B. 
Accommodation of Upstream Drainage. Culverts and other drainage facilities shall be large enough to accommodate potential runoff from the entire upstream drainage area, whether inside or outside the development. Such facilities shall be subject to review and approval by the City-appointed engineer.
C. 
Effect on Downstream Drainage. Where it is anticipated by the City-appointed engineer that the additional runoff resulting from the development will overload an existing drainage facility, the City shall withhold approval of the development until provisions have been made for improvement of the potential condition or until provisions have been made for storage of additional runoff caused by the development in accordance with City standards.
D. 
Easements. Where a development is traversed by a watercourse, wetland, drainage way, channel or stream, the City may require a dedication of a stormwater easement or drainage right-of-way conforming substantially with the lines of such watercourse and such further width as will be adequate for conveyance and maintenance.
A. 
Underground Utilities. All utility lines including, but not limited to, those required for electric, communication, lighting and cable television services and related facilities shall be placed underground, except for surface mounted transformers, surface mounted connection boxes and meter cabinets which may be placed above ground, temporary utility service facilities during construction, and high capacity electric lines operating at 50,000 volts or above. The following additional standards apply to all new land divisions, in order to facilitate underground placement of utilities:
1. 
The developer shall make all necessary arrangements with the serving utility to provide the underground services. Care shall be taken to ensure that all above ground equipment does not obstruct circulation and access aisles or impede vision clearance areas for vehicular traffic (Chapters 16.120 and 16.132);
2. 
The City reserves the right to approve the location of all surface mounted facilities;
3. 
All underground utilities, including sanitary sewers and storm drains installed in streets by the developer, shall be constructed prior to the surfacing of the streets; and
4. 
Stubs for service connections shall be long enough to avoid disturbing the street improvements when service connections are made.
B. 
Easements. Easements shall be provided for all underground utility facilities.
C. 
Exception to Undergrounding Requirement. The standard applies only to proposed land divisions and large-scale developments. An exception to the undergrounding requirement may be granted due to physical constraints, such as steep topography or existing development conditions.
Easements for sewers, storm drainage and water quality facilities, water mains, electric lines or other public utilities shall be dedicated on a final plat, or provided for in the deed restrictions. See also Chapter 16.212, Site Design Review, and Chapter 16.216, Land Divisions and Lot Line Adjustments. The developer or applicant shall make arrangements with the City, the applicable district, and each utility franchise for the provision and dedication of utility easements necessary to provide full services to the development. The City's standard width for public main line utility easements shall be 20 feet unless otherwise specified by the utility company, applicable district, or City-appointed engineer.
No public improvements, including sanitary sewers, storm sewers, streets, sidewalks, curbs, lighting, parks, or other requirements shall be undertaken except after the plans have been approved by the City, permit fee paid, and permit issued. The permit fee is required to defray the cost and expenses incurred by the City for construction and other services in connection with the improvement. The permit fee shall be set by resolution of the City Commission. The City may require the developer or land divider to provide bonding or other performance guarantees to ensure completion of required public improvements. See also Section 16.212.040, Site Design Review, and Chapter 16.216, Land Divisions and Lot Line Adjustments.
A. 
Conformance Required. Improvements installed by the developer either as a requirement of these regulations or at his/her own option, shall conform to the requirements of this chapter, approved construction plans, and to improvement standards and specifications adopted by the City.
B. 
Adopted Installation Standards. The Oregon Standard Specifications for Construction (combined APWA/ODOT standards) shall be a part of the City's adopted installation standard(s); other standards may also be required upon recommendation of the City-appointed engineer.
C. 
Commencement. Work shall not begin until the City has been notified in advance and all required permits have been issued.
D. 
Resumption. If work is discontinued for more than one month, it shall not be resumed until the City is notified.
E. 
City Inspection. Improvements shall be constructed under the inspection and to the satisfaction of the City. The City may require minor changes in typical sections and details if unusual conditions arising during construction warrant such changes in the public interest. Modifications requested by the developer shall be subject to land use review under Chapter 16.228, Modifications to Approved Plans and Conditions of Approval. Any monuments that are disturbed before all improvements are completed by the subdivider shall be replaced prior to final acceptance of the improvements.
F. 
Engineer's Certification and As-Built Plans. A registered civil engineer shall provide written certification in a form required by the City that all improvements, workmanship and materials are in accord with current and standard engineering and construction practices, conform to approved plans and conditions of approval, and are of high grade, prior to City acceptance of the public improvements, or any portion thereof, for operation and maintenance. The developer's engineer shall also provide four set(s) of "as-built" plans, in conformance with the City-appointed engineer's specifications, for permanent filing with the City.
